Problems solved by technology

[0002] Although the traditional P-type automatic filter can also use the pressure of the pipeline itself to backwash the filter, it needs to close the water flow guide valve and use the water pressure filtered by the filter on the inlet side to backwash the filter. The filter screen on the water inlet side cannot be backwashed, and it can only be flushed after the water flow guide valve is opened. There is a dead angle for backwashing of the filter screen, and the backwashing is not complete

Abstract

The invention relates to a novel P-typed fully automatic filter, which is an online novel P-typed filter carrying out a filter net backwashing by effectively adopting the self pressure of pipelines. The filter net has the bidirectional opening and is divided into a multi-chamber by a retaining plate; the backwashing of the filter net multi-chamber is carried out one by one; the backwashing is thorough without dead angles and with good effect, and the water supply is continuous when the backwashing is carried out. The novel P-typed fully automatic filter has two types: one that the water inlet and the water outlet are directly communicated and the other one that the water inlet and the water outlet are straight angles. The invention has the advantages of simple structure, sound design, convenient manufacture, low cost, and is the updating regeneration products of the traditional P-typed filters.

Description

【Technical field】 [0001] The invention relates to a new P-type fully automatic filter, in particular to an online new P-type filter which can effectively utilize the pressure of the pipeline itself to backwash the filter screen, and belongs to the field of filters. 【Background technique】 [0002] Although the traditional P-type automatic filter can also use the pressure of the pipeline itself to backwash the filter, it needs to close the water flow guide valve and use the water pressure filtered by the filter on the inlet side to backwash the filter. The filter screen on the water inlet side cannot be backwashed. It can only be flushed after the water flow guide valve is opened. 【Content of invention】 [0003] The purpose of the present invention is to provide a new P-type fully automatic filter with simple structure, reasonable design, convenient manufacture, low cost and better backwashing effect. [0004] In order to achieve the above object, the present invention has ...
