Multi-station stock solution filtering system

Abstract

The invention discloses a multi-station stock solution filtering system which comprises a screen exchanger main body and is characterized in that a plurality of plunger holes which are through left and right and are distributed up and down are formed in the screen exchanger main body, plungers capable of axially moving are respectively arranged in the plunger holes, and the outer circles of the plungers are in rigid sealing fit with the inner walls of the plunger holes; the right end of the plunger is in transmission connection with a hydraulic cylinder with a displacement sensor, the plunger is provided with a pre-filtering channel, a filtering cavity and a post-filtering channel which are sequentially communicated in the radial direction, and a filtering assembly is arranged in the filtering cavity in a matched mode. A pre-filtering exhaust groove communicated with the pre-filtering channel, a top exhaust groove communicated with the filtering cavity and a post-filtering exhaust groove communicated with the post-filtering channel are further formed in the outer circle of the plunger; an inlet adapter and an outlet adapter are arranged on the front side and the rear side of the screen exchanger body respectively, correspondingly, the screen exchanger body and the inlet adapter are provided with liquid inlet channels which are communicated with the pre-filtering channels in parallel, and the screen exchanger body and the outlet adapter are provided with liquid outlet channels which are communicated with the post-filtering channels in parallel. The method is stable, efficient and good in continuity.

Description

technical field [0001] The invention relates to an improved invention of a raw liquid filtering device, in particular to an improved invention of a multi-station raw liquid filtering system, which is mainly used for filtering the raw liquid of cellulose spinning. Background technique [0002] The existing raw liquid filtration system uses single plunger or double plunger for filtration, so the filtration area is small and the filtration efficiency is low, which makes the material stay in the filtration system for a long time, affecting product quality, and at the same time, it will affect the production line when changing the screen. Normal operation, and there is gas in the plunger filter chamber after the screen has been changed, and the gas is easy to mix into the product, reducing product quality, and the gas will also affect the pressure difference before and after filtration, affect the working stability, and cannot achieve the continuity of filtration. Product disconn...
