Abstract:
Provided is an anti-clogging raw water drinking machine for removing heavy metal, which comprises a cylinder body (1), a piston rod (4), a piston (41), a first stage purification unit and a second stage purification unit. The first stage purification unit comprises a filter core (6) provided at the bottom of the cylinder body (1). The inner space of the filter core (6) forms a first channel (5) for the water passing therethrough. The second stage purification unit located above the first stage purification unit comprises an inner core (9) made from an adsorbent material, a macromolecule adsorption membrane (10) surrounding the periphery of the inner core (9), and an ultrafiltration membrane (11) surrounding the periphery of the macromolecule adsorption membrane (10). The inner space of the inner core (9) forms a second channel (8) for the water passing therethrough, which is communicated with the first channel (5). The lower end part of the piston rod (4) is located in the second channel (8). The two stage purification units are used for removing pollutants in the water, for example, heavy metal etc., so as to obtain the potable water which meets the potable water standard. Moreover, the raw water drinking machine has backwashing function. The piston type water pumping device provided can use the machine in the absence of power supply.
