Hydraulic driven automatic self-cleaning filter

Abstract

The invention discloses a hydraulic driven automatic self-cleaning filter. A sewage suction pipe comprises a main pipe and a plurality of branch pipes. The main pipe and the branch pipes are communicated with each other. Each branch pipe is provided with a suction nozzle, and each suction nozzle is tightly arranged on the internal wall of a filter core. One end of the main pipe is sealed and is rotatingly arranged on an upper end socket, and the other end of the main pipe is rotatingly arranged on a separation plate, penetrates the separation plate, and stretches into a sewage discharge cavity. The end, which stretches into the sewage discharge cavity, of the main pipe is provided with a hydraulic whirl spraying pipe, which comprises at least one Z-shaped pipe with two opened ends. The Z-shaped pipe is vertical to the rotation axis of a sewage discharge pipe, moreover, the Z-shaped pipe and the sewage discharge pipe are communicated with each other so as to conveniently discharge the sewage in the sewage discharge pipe into the sewage discharge cavity, and the couple moment of opposite force generated by the water discharged from the Z-shaped pipe drives the sewage suction pipe to rotate so as to control the suction nozzles to wash the filter core. The provided filter does not need an external power source; the sewage suction pipe is driven by self hydraulic force to rotate and suck the sewage; the cost is low, the structure is simple, the energy consumption is low, and the efficiency is high.

Description

technical field [0001] The invention relates to a device used in the field of filtration and separation, in particular to a hydraulically driven fully automatic self-cleaning filter. Background technique [0002] As a new type of filtration technology, the screen type self-cleaning filter has the advantages of high degree of automation, small pressure loss, and simple structure, and is widely used in industry, agriculture, municipal, marine and other fields. At present, the water inlet and outlet of common filters are often not on the same line, the pipeline layout is difficult, and the filter cleaning often needs to be driven by a motor, which is costly and consumes a lot of energy. Contents of the invention [0003] The purpose of the present invention is to provide a fully automatic self-cleaning filter driven by water to solve the problems of high cost and high energy consumption that the cleaning device in the prior art needs to be driven by a motor. [0004] The pre...
