Self-flushing water-saving irrigation water filter

Abstract

The invention discloses a self-flushing water-saving irrigation water filter. The self-flushing water-saving irrigation water filter comprises a sand settling device; the top of the sand settling device is provided with a separation cylinder; the top of the separation cylinder is provided with a fixed cylinder; a filter sieve cylinder is movably arranged in the fixed cylinder; the back end of the left side of the separation cylinder is communicated with a water inlet pipe; the top of the right side of the fixed cylinder is communicated with a water outlet pipe; and the top of the fixed cylinder is fixedly connected with a motor. According to the self-flushing water-saving irrigation water filter, a motor is adopted to drive a rotating rod to rotate, the rotating rod is used for driving a pair of cleaning brushes to clean the internal wall of the filter sieve cylinder through a concave plate, so that effective cleaning on the filter sieve cylinder is realized, and problems in the prior art that in using of a conventional self-flushing filter, only rotating water flow is adopted for flushing of a sieve cylinder, no cleaning mechanism is adopted, a part of impurities are left in the sieve pores of the sieve cylinder, and self cleaning effect of the self-flushing filter is reduced are solved, and it is convenient for using by people.

Description

technical field [0001] The invention relates to the technical field of irrigation water filters, in particular to a self-flushing water-saving irrigation water filter. Background technique [0002] The filter is an indispensable device on the conveying medium pipeline. It is usually installed at the inlet end of the pressure reducing valve, pressure relief valve, fixed water level valve, and other equipment of the Fanggong filter. The filter is composed of a cylinder, a stainless steel screen, It is composed of sewage discharge part, transmission device and electrical control part. [0003] The self-rinsing filter is a common irrigation filter, but the existing self-rinsing filter only washes the screen drum through the rotating water flow, and does not have a certain cleaning mechanism, resulting in some impurities still remaining in the screen drum. The inside of the sieve reduces the self-cleaning effect of the self-flushing filter, which is not convenient for people to ...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a self-flushing water-saving irrigation water filter, which has the advantage of being able to effectively clean the screen cylinder, and solves the problem that the existing self-flushing filter only passes the rotating water flow to the screen. There is no certain cleaning mechanism, which results in some impurities still remaining inside the sieve holes of the screen drum, which reduces the self-cleaning effect of the self-rinsing filter.
