Abstract

The invention discloses a pre-filter with automatic scraping and blowdown functions. The pre-filter comprises a filter casing, wherein a blowdown port assembly and an outer casing for sealing the blowdown port assembly are arranged at the lower end of the filter casing; the blowdown port assembly is connected with a filter net skeleton which is positioned in the filter casing; the blowdown port assembly comprises a blowdown pipe and a ball valve, and the ball valve is used for blocking or opening the blowdown pipe; the blowdown pipe can be controlled to automatically rotate; the ball valve canbe automatically controlled to open or close. The pre-filter has the advantages that the automatic blowdown and automatic cleaning functions are realized; the convenience in use is realized; in the use process, the automatic cleaning and blowdown functions can be realized by only presetting the automatic blowdown and cleaning intervals, and the use experience is better.

Description

technical field [0001] The invention relates to a pre-filter, in particular to a pre-filter with automatic scraping and sewage discharge functions. Background technique [0002] The existing filters on the market require manual sewage discharge when sewage is discharged, and the operator needs to remember the work of sewage discharge by virtue of memory. Therefore, it is inconvenient to use, and both sewage discharge and scraping require manual manual operation. Processing, waste of time and manpower, and poor user experience. SUMMARY OF THE INVENTION [0003] In view of the above problems, the present invention provides a pre-filter with functions of automatic scraping and cleaning. The filter has the functions of automatic cleaning and automatic cleaning, and is convenient to use. When in use, it only needs to preset the automatic drainage and cleaning. It can realize automatic cleaning and sewage discharge at a time interval, and the use experience is good. [0004] I...
