firstly, water enters the filtering shell 11 from the water inlet pipe 12 and impacts on the outer surface of the flow isolating pipe 16, then the water flows downwards from the interlayer between the filtering shell 11 and the flow isolating pipe 16, then the water enters the interlayer between the outer surface of the external threaded pipe 24 and the inner wall of the filtering shell 11, then the water flow gradually decelerates in the interlayer between the outer surface of the external threaded pipe 24 and the inner wall of the filtering shell 11, then particles in the water move downwards relative to the water body under the dual action of inertia force and gravity, the effect of precipitating the particles is realized, then the particles are precipitated and gathered on the bottom surface of the inner cavity of the filtering shell 11, the concentration of the particles in the water is reduced, then the original water in the interlayer between the outer surface of the external threaded pipe 24 and the inner wall of the filtering shell 11 enters the interlayer between the flow isolating pipe 16 and the upper filtering net pipe 15 under the hydraulic action, and then the water passes through meshes on the upper filtering net pipe 15 and enters the interior of the upper filtering net pipe 15, the residual particles in the water are intercepted on the surface of the

lower convex pipe 305, the water through hole 306, the external threaded pipe 24, the water through hole 302, the monitoring corrugated pipe 51, the slope hole 53, the corresponding interception hole 606, the interception conical net 607 and is discharged from the water outlet pipe 14 for drip irrigation until the irrigation is finished, at this time, the water inflow in the filter shell 11 is stopped, then the particles intercepted on the surface of the upper filter screen pipe 15 fall off and gradually sink under the action of gravity, then the particles are deposited on the bottom surface of the inner cavity of the filter shell 11 and are discharged by the slag discharge pipe 13, when the upper filter screen pipe 15 is damaged in the irrigation process, the particles intercepted on the surface of the upper filter screen pipe 15 enter the upper filter screen pipe 15 through the damaged position and move with the water flow, causing the leakage of the particles, intercepting the leaked particles by an intercepting cone net 607, gradually gathering the leaked particles in the intercepting cone net 607, increasing the meshes covered by the particles on the intercepting cone net 607, increasing the thrust force of the intercepting cone net 607 in the water flow, applying a downward thrust force to the liquid discharge block 52 by the intercepting cone net 607 through the inner wall of the intercepting hole 606 and the intercepting plate 603, then moving the liquid discharge block 52 downwards and pulling the monitoring corrugated pipe 51, then
