A device and method for automatically cleaning impurities in a rotary valve

Abstract

The invention discloses a device and method for automatically cleaning impurities in a rotary valve, which comprises a valve body, one end of the valve body is a water inlet pipe, the other end of the valve body is a water outlet pipe, and the valve body is connected with a runner through a first rotating shaft. There are several impurity collection pipes ring-shaped in the wheel, at least one impurity collection pipe is set in the water inlet pipe, and the impurity collection pipe connects the water inlet pipe with the cavity of the valve body; the valve body is also rotatably connected with a passive bevel gear, and the passive bevel gear is connected There is a driving mechanism, the passive bevel gear is eccentrically provided with a driving rod, the first rotating shaft fixed sleeve is provided with a bifurcated rod, and the driving rod is in contact with the bifurcated rod; the valve body is also connected with a cleaning mechanism for cleaning the impurity collection pipe. The device of the invention has the advantages of pre-cleaning sewage impurities in the pipeline, prolonging the service time of the valve, reducing the number of times of manual cleaning, reducing the difficulty of cleaning, and improving the use efficiency.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to an automatic cleaning device and cleaning method for impurities in a rotary valve. Background technique [0002] Sewage treatment and water recycling are important components in the field of environmental protection. With the rapid development of the domestic economy and the improvement of residents' living standards, the annual discharge of industrial sewage and domestic sewage is also increasing. Sewage treatment needs to be carried out through drainage valves. However, after using the existing drainage valve for a period of time, the valve will be clogged due to the dirt wrapped around the surface of the valve core. It is necessary to pre-clean the impurities in the pipeline to prolong the service life of the valve and reduce the number of cleanings. Contents of the invention [0003] In order to solve the above-mentioned problems in the prior art, an automatic cleaning devic...

Problems solved by technology

[0002] Sewage treatment and water recycling are important components in the field of environmental protection. With the rapid development of the domestic economy and the improvement of residents' living standards, the annual discharge of industrial sewage and domestic sewage is also increasing. Sewage treatment needs to be carried out through drainage valves. However, after using the existing drainage valve for a period of time, the valve will be blocked due to the dirt winding on the surface of the valve core. A method is needed to pre-clean the impurities in the pipeline, prolong the service life of the valve, and reduce the number of cleaning times.
