Filter cleaning apparatus

Abstract

A filter cleaning apparatus comprises a filter core, a gap is arranged between the filter core and each of the sidewall of a shell and an intermediate disk, gaps are connected to form a filtrate cavity, the upper portion of the shell is provided with a filtrate outlet, the filtrate outlet is connected with the filtrate cavity, the filter core is fixed on the intermediate disk of a filter, the intermediate disk is sleeved on a main shaft, the main shaft is connected with a drive device, the drive device is arranged at the top of the shell of the filter, the lower portion of the shell is provided with a filtrate inlet, the filtrate inlet is connected with the filter core, a dirt outlet is arranged at the bottom of the shell and is connected with a solenoid valve, a pressure difference controller is arranged in the shell, cleaning brushes connected with supporting skeletons are arranged in the filter core, the supporting skeletons are connected with a telescoping rod, a sliding sleeve is sleeved on the telescoping rod in a sliding manner, and the telescoping rod is connected with the drive device through the main shaft. The telescoping rod is elongated to push the sliding sleeve close to the supporting skeletons, and the supporting skeletons are pushed by the supporting rods and are opened, so the cleaning brushes contact with the inner wall of the filter core of the filter to clean dirt attached to the inside of the filter core, thereby the apparatus has the advantages of time saving, labor saving and high working efficiency.

Description

technical field [0001] The invention relates to a filter, in particular to a filter cleaning device. Background technique [0002] At present, the filter is an indispensable and important link in industrial production and manufacturing. With the continuation of the filtration process, the solid-phase impurities in the liquid are trapped on the surface of the filter element, causing the pressure drop in the filter element to increase, and the filtration resistance to increase. The efficiency drops. At this time, it is generally necessary to interrupt the filtration operation, replace the filter element or take it out for cleaning. The filter element is automatically cleaned. This kind of self-cleaning not only wastes water, but also is not clean, especially the stubborn impurities remaining on the surface of the filter medium cannot be effectively cleaned. Contents of the invention [0003] The invention provides a filter cleaning device, aiming at solving the problems of ...
