Title:
FOREIGN MATTER REMOVAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/248331
Kind Code:
A1
Abstract:
In a foreign matter removal device (1) that removes foreign matter contained in fluid in piping by using a swirling flow generated within a trap section (2), the fluid is caused to flow into the trap section (2) and separated into an inner fluid flowing inside and an outer fluid flowing outside a separation section (5). First foreign matter, which has a specific gravity higher than the fluid contained in the outer fluid, is captured in the gap between the inner wall of the trap section (2) and the separation section (5), and second foreign matter, which has a specific gravity lower than the fluid contained in the inner fluid, is discharged to the outside from a foreign matter discharging means (8) through a foreign matter discharging means connection part (9) in the center of the ceiling of the trap section (2) by reducing the swirling flow with a flow-regulating plate (10).
