Self-cleaning filter

Abstract

The invention belongs to the technical field of water treatment equipment, and specifically relates to a self-cleaning filter, which comprises a filter cylinder and a filtering core cylinder insertedinto the filter cylinder, wherein end covers are arranged at the two ends of the filtering core cylinder, a to-be-filtered liquid storage area is defined by the inner wall of the filter cylinder, theouter wall of the filtering core cylinder and the end covers at the two ends, a filtrate storage area is defined by the end covers at the two ends and the inner wall of the filtering core cylinder, adriving impeller is arranged at the end, close to a cleaning liquid input pipe, of the filtering core cylinder, and a cleaning liquid sprayed out of the cleaning liquid input pipe drives the driving impeller to rotate and drives the filtering core cylinder to rotate. According to the invention, the cleaning liquid is pumped into the filter through the additionally-arranged pipeline, so that the unpowered self-cleaning of the filter is realized; and the flow path of the cleaning liquid is opposite to the flow path during normal filtration, and the self-rotation of the filtering core cylinder iscombined, so that the self-cleaning efficiency can be improved, and a good self-cleaning effect is achieved.

Description

technical field [0001] The invention belongs to the technical field of water treatment equipment, and in particular relates to a self-cleaning filter. Background technique [0002] The filter is an indispensable device on the pipeline of the conveying medium. It usually consists of a cylinder, a filter screen and other parts. After the liquid to be used passes through the filter screen of the filter, the impurities contained in it are blocked. After a period of use , the filter screen of the filter must be blocked by a large amount of impurities, which will affect the filtering effect of the filter. Therefore, the filter often needs to be cleaned regularly. The traditional method is to disassemble the filter, take out the filter screen, and wait until the cleaning is completed. Reloading, this method is time-consuming and laborious, and the disassembly and assembly of the filter is relatively loaded down with trivial details; Therefore, more filters with self-cleaning functi...

Problems solved by technology

However, the water flow direction of this self-cleaning filter in the specific cleaning process is consistent with the water flow direction of the filter when it is in use, causing the magazines on the filter element to be not easily removed, and the cleaning efficiency is low, and the cleaning effect is poor.
