Device and method for automatically clearing impurities in rotary valve

Abstract

The invention discloses a device and method for automatically clearing impurities in a rotary valve. The device 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, the valve body is rotationally connected to a rotating wheel through a first rotating shaft, a plurality of impurity collecting pipes are annularly arranged in the rotating wheel, at least one impurity collecting pipe is arranged in the water inlet pipe, the impurity collecting pipes enable the water inlet pipe to communicate with a cavity of the valve body, the valve body is further rotationally connected to a driven bevel gear, the driven bevel gear is connected to a driving mechanism, the driven bevel gear is eccentrically provided with a shifting rod, the first rotating shaft is fixedly sleeved with a branch rod, the shifting rod makes contact with the branch rod, the valve body is further connected to a clearing mechanism used for clearing the impurity collecting pipes. The device and method have the advantages of pre-clearing waste water impurities in the pipeline, prolonging the service life of the valve, reducing the manual cleaning frequency, reducing the cleaning difficulty 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...

[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.
