Description:
A SHREDDER FOR USE IN THE FLOW LINE

TECHNICAL FIELD

The invention relates to a shredder for enabling the coarse particles in the liquid carried in a flow line to be at least partially shredded and transported, comprising a body connectable to the flow line, a cutting screen having at least one hole in the said body through which the liquid is passed, at least one shredding unit for at least partially scraping the surface of the said cutting screen and shredding the coarse particles and at least one drive element connected by means of at least one transfer unit to at least partially move the said shredding unit.

BACKGROUND

In-line shredders are used to facilitate the transfer of solid materials such as stone, wood, metal, etc., as well as fibrous materials such as oakum, rope, and straw, which are transported with fluid during the discharge or transfer of slurry tank, by shredding them to the minimum required size. Thus, it is ensured that the liquid is transferred smoothly without causing clogging in the pumps and lines. In addition to shredding, in-line shredders also ensure the separation of large and hard pieces that can damage the pump or installation, block the line, and cannot be shredded from the liquid with its stone holder chamber.

Application No. DE202004008476U1 , known in the literature, relates to an embodiment of crushing solids in liquid fertilizer. Accordingly, a rotating blade is positioned adjacent to a plate with flow openings thereon. The invention provides a coupling embodiment in place of the existing pin blade coupling. Thus, it is aimed to eliminate problems caused by the pin connection, such as the inability to maintain the distance between the blade and the plate.

The shredding blades in the in-line shredders known in the present art allow the continuous shredding of waste materials . However, during this process, the blades can become blunt and the distance between them and the cutting screen can increase. This leads to a reduction in the shredding function and the inability to shred as desired. This situation may cause problems up to the blockage of the flow line in the long term. As a result, all the above-mentioned problems have made it necessary to make an innovation in the relevant technical field.

BRIEF DESCRIPTION OF THE INVENTION

The present invention relates to a shredder for eliminating the above-mentioned disadvantages and bringing new advantages to the relevant technical field.

One object of the invention is to provide a shredder for shredding waste in a flow line so that it can be transported in a small form in the flow line.

Another object of the invention is to provide a shredder whose shredding feature is continuous and whose shredding feature is improved.

In order to achieve all the above-mentioned objectives and those that will emerge from the detailed description below, the present invention is a shredder for enabling the coarse particles in the liquid carried in a flow line to be at least partially shredded and transported, comprising a body connectable to the flow line, a cutting screen having at least one hole in the said body through which the liquid is passed, at least one shredding unit for at least partially scraping the surface of the said cutting screen and shredding the coarse particles and at least one drive element connected by means of at least one transfer unit to at least partially move the said shredding unit. Accordingly, its novelty is that it comprises at least one rotation shaft provided on the transfer unit for allowing the shredding unit to continuously apply pressure to the cutting screen, at least one tension element for connecting the said rotation shaft to the shredding unit by tensioning, and at least one bellows configured to contact the shredding unit on the cutting screen. This ensures that the same compressive force is constantly maintained between the shredding unit and the cutting screen.

A possible embodiment of the invention is characterized in that the said bellows is positioned between the body and the drive element. Thus, the shredding unit is in fully contact with the cutting screen.

Another possible embodiment of the invention is characterized in that the bellows is positioned between a flange adapter positioned on the drive element and the body. Thus, the shredding unit is in fully contact with the cutting screen Another possible embodiment of the invention is characterized in that the bellows comprises at least one plate and at least one inflatable element. Thus, a flexible bellows element is obtained.

DETAILED DESCRIPTION OF THE INVENTION

In this detailed description, the subject matter of the invention is explained only by means of examples that will not have any limiting effect for a better understanding of the subject matter.

Figure 1 illustrates a representative exploded view of the shredder (1 ) of the invention. Accordingly, the shredder (1 ) of the invention essentially allows the coarse particles in the liquid containing coarse particles to be at least partially shredded and transported. The shredder (1) is essentially an in-line shredder (1). The shredder (1) is used during the discharge or transfer of slurry tanks to facilitate the transfer of hard materials such as stones, wood, and metal, as well as fibrous materials such as oakum , ropes, straw, etc., which are transported with the fluid, by shredding them to the minimum required size. Thus, it is ensured that the fluid is transferred smoothly without causing clogging in the pumps and lines. The shredder (1) contains various components to perform shredding process and these components work in sync with each other.

The shredder (1) is provided with at least one body (10). The said body (10) allows the shredder (1 ) to be positioned on a flow line. The body (10) is provided with at least one body wall (11). The said body wall (11 ) allows the body to be positioned on the flow line. The body wall (11 ) is essentially cylindrical and has a flow opening (12) in its center. The fluid having the shredded elements is passed through the flow opening (12). The body (10) is provided with at least one leaning wall (13), which is opposite to the body wall (11). The said leaning wall (13) allows the part of the shredder (1) outside the flow opening (12) to be retained on the body (10).

The shredder (1) is provided with at least one cutting screen (20). The cutting screen (20) is the part that separates the pre-shredding and post-shredding sections on the flow line. The elements passing through the cutting screen (20) are passed through in the flow line in a shredded state. The cutting screen (20) is fitted in the flow opening (12) on the body (10). In the preferred embodiment of the invention, the cutting screen (20) is disposed of with the flow opening (12). The cutting screen (20) is provided with at least one hole (21). There is essentially a plurality of said holes (21 ) on the cutting screen (20). Thus, it is ensured that the elements desired to be passed through in the flow opening (12) are transferred with size not larger than the size of the hole (21).

The shredder (1) is provided with at least one shredding unit (30). The said shredding unit (30) is essentially positioned adjacent to the cutting screen (20). The shredding unit (30) ensures that the elements that cannot pass through the cutting screen (20) are scraped from the surface of the cutting screen (20) and at least partially shredded during this scraping. For this purpose, the shredding unit (30) comprises at least one holder (31) and at least one blade (32) connected to the said holder (31). There are three of the said holders (31) provided, extending essentially from the center of the cutting screen (20) towards the outer edges of the cutting screen (20). The holder (31 ) allows the said blade (32) to be moved around the surface of the cutting screen (20). Therefore, the shredder (1) is provided with as many blades (32) as there are holders (31). The said blade (32) is detachably connected to the holder (31). In this way, it is possible to replace the blade (32) in case of blunting. The shredder (1) is provided with at least one drive element (40). The said driving element (40) is connected to the shredding unit (30) by means of at least one transfer unit (50). The drive element (40) is essentially an electric motor enabling electrical energy to be converted into rotational motion energy. The transfer unit (50) allows this rotational movement to be transferred to the shredding unit (30). In this way, depending on the movement taken from the drive element (40), it is ensured that the shredding unit (30) is continuously moved on the surface of the cutting screen (20). There may also be at least one reducer (41) to allow the force transfer between the drive (40) and the transfer unit (50) to be adjusted. In this way, it can be ensured that the drive elements (40) with less power can produce enough power for the system.

The transfer unit (50) on the shredder (1) has a unique structure. The transfer unit (50) allows transferring the movement received from the drive element (40) to the shredding unit (30) as well as adjusting the amount of pressure to be applied by the shredding unit (30) to the cutting screen (20). There is at least one rotation shaft (51) on the transfer unit (50) for this purpose. The said rotation shaft (51 ) extends between the drive element (40) and the holder (31). There may be at least one mounting opening (22) on the cutting screen (20) and the leaning wall (13) so that the rotation shaft (51) can extend between these two parts. The rotation shaft (51) is fixedly connected by the drive element (40) or the reducer (41) while its tension is adjustably connected by the shredding unit (30). For this purpose, at least one tension element (52) is provided on the transfer unit (50). The said tension element (52) is essentially in the form of a shaft and bolt and may be configured in such a way that the amount of pressure that the holder (31) exerts on the cutting screen (20) can be adjusted by rotating the bolt around itself.

Figure 2 illustrates a representative cross-sectional view of the shredder (1 ) of the invention. Accordingly, the shredder (1 ) has a structure wherein the amount of leaning and friction between the cutting screen (20) and the shredding unit (30) remains constant. There is at least one bellows (60) on the shredding unit (30) for this purpose. There is at least one plate (61) on the said bellows (60). Two plates are provided on the bellows (60) so that the said plate (61 ) is opposite each other. At least one inflatable element (62) is provided between the plates (61) on the bellows (60). The said inflatable element (62) may have an expanding volume depending on the filling of the interior with air. The inflatable element (62) is essentially configured to exert continuous pressure on the cutting screen (20) to the shredding unit (30) by inflating. For this purpose, the bellows (60) is positioned between the body (10) and the transfer unit (50). The bellows (60) is essentially positioned between the leaning wall (13) on the body and a flange adapter (42) provided between the rotation shaft (51) and the reducer (41 ). The said flange adapter (42) allows a connection between the rotation shaft (51) and the reducer (41 ). The inflatable element (62) is provided with at least one sensor (not shown in the figures). The said sensor is configured to detect the amount of air pressure on the inflatable element (62). The sensor is essentially a manometer and detects the pressure of the inflatable element (62).

In a possible embodiment of the invention, the assembly and operation scenario of the shredder (1) is as follows;

The cutting screen (20) is placed on the body wall (11 ),

The rotation shaft (51) is passed through the mounting opening (22) on the cutting screen (20),

From one side of the rotation shaft (51), the bellows (60), flange adapter (42), reducer (41) and drive element (40) are mounted respectively,

On the other side of the rotation shaft (51) the shredding unit (30) is mounted, and the tension element (52) is tightened to the rotation shaft (51) using nuts,

The inflatable element (62) on the bellows (60) is inflated by a predetermined amount depending on the contact load to be applied by the shredding unit (30) to the cutting screen (20),

As the elements carried through the flow line pass through the cutting screen (20), they are crushed by the shredding unit (30) and passed through the holes (21),

If there is an element in the flow line that will not pass through the holes (21), With the compressibility of the bellows, the shredding unit moves away from the cutting screen. In this way, possible breakage that may occur in the shredding unit is prevented.

With this whole embodiment, it is ensured that the contact load between the shredding unit (30) and the cutting screen (20) is kept constant. The tension element (52) allows the shredding unit (30) to be continuously contacted on the cutting screen (20). In the event that the blades (32) in the shredding unit (30) are worn, the inflatable element (62) on the bellows (60) contacts the shredding unit (30) to the cutting screen (20) at the same load. For this purpose, the inflatable element (62) is inflated depending on the data received from the sensor. In this way, a continuous friction surface is formed between the cutting screen (20) and the blades (32). Thus, continuous flow is provided through the shredder (1) without blocking the flow line. The protection scope of the invention is specified in the attached claims and cannot be limited to those explained for illustrative purposes in this detailed description. It is evident that those skilled in the art may exhibit similar embodiments in light of the above-mentioned facts without drifting apart from the main theme of the invention.
