Introduction

Sucking type self-cleaning filter lefilter

Sucking type self-cleaning filter

Sucking type self-cleaning filter automatically filters raw water, automatically cleans the filter screen and automatically discharges sewage. The whole process is automatic control without manual operation. The cleaning sewage system provides uninterrupted water supply. Sucking type automatic self-cleaning filter control mode can be automatic or manual.

Application Power industry, reverse osmosis pre-stage, petrochemical, chemical, food and beverage, automotive, industrial, metallurgy, papermaking, pharmaceutical, microelectronics, environmental protection water treatment and other industries.
Filter medium Water suspended solids, particulate matter, dirt, bacteria and algae water quality, corrosion, etc

Working principle

First of all, the water passes through the coarse filter screen at the inlet to remove the larger impurities, and then passes through the fine filter screen to remove the smaller impurities. In the filtration process, the fine filter screen gradually accumulates dirt and impurities, forming a impurity layer which is piled up in the inner side of the fine filter screen, then a differential pressure is formed on the inside and outside sides of the fine filter screen.
When the pressure difference of the filter inlet and outlet reaches the preset value or when the preset cleaning time is reached or when the filter is manual preset, the automatic self-cleaning process will begin, and the water supply is not cut off during this self-cleaning process. The whole self-cleaning process consists of two steps: the sewage discharge valve is opened, the water pressure in the cleaning chamber and the sewage suction pipe greatly decreases, and there will be a pressure difference between the filter element and the sewage suction pipe, the suction pipe and the cleaning chamber will produce a suction process through the suction nozzle, forming a sewage suction process. Impurities in the inner wall of the screen are sucked up by the suction scanner and discharged through the drain valve. At the same time, the external bidirectional motor drives the suction scanner to scan spirally. The combination of axial movement and rotary movement of the suction pipe will completely clean the inner surface of the filter screen. The whole process takes only a few seconds. The drain valve closes at the end of cleaning. The filter begins to prepare for the next flush cycle.
Cleaning mode: The filter's back cleaning mode adopts motor driving and suction nozzle sucking. The reducer and motor drive the suction device and suction nozzle to rotate, and suction nozzle sucks impurities on the inner surface of the fine screen to complete the suction. The whole operation process of the self-cleaning filter is controlled by an intelligent control box equipped with it. Control mode is optional (pressure difference, time, manual and PLC control).
