Abstract

The utility model discloses a PVC (Polyvinyl Chloride) filter plate. The PVC filter plate comprises a filter plate body, wherein the filter plate body is a filter plate made of PVC; the filter plate body has four layers including a grating plate serving as a first layer, a cavity layer serving as a second layer, a sieve plate serving as a third layer; the grating plate is provided with a big through hole; the sieve plate serving as the third layer is provided with a small sieve pore; and a stainless steel filter screen is arranged below the sieve plate layer serving as the third layer. The PVC filter plate provided by the utility model has good corrosion resistance, is good for dispersing filtered solid impurities as big solid impurities are filtered by the grating plate and then solid-liquid mixing is further performed in the middle cavity layer when the PVC filter plate is used; and solid-liquid mixture is filtered by the small sieve pore of the sieve plate and finally further filtered through the filter screen, so that good filtering effects are obtained.

Description

The PVC filter

Technical field

The utility model relates to a kind of plant equipment field, relates in particular to a kind of PVC filter.

Background technology

Filter generally is installed in plant equipment and be used for filters solid impurity, in the prior art sieve plate mainly usefulness be metal material, metal material is wear-resisting and corrosion resistance is poor, needs to change after using a period of time, service life is short.

The utility model content

The utility model purpose: the utility model provides the PVC filter of a kind of good corrosion resistance, good filtration effect in order to solve the deficiencies in the prior art.

Technical scheme: a kind of PVC filter, comprise the filter body, described filter body is the filter that PVC makes, described filter body has four layers, and ground floor is flase floor, and the second layer is cavity layer, the 3rd layer is the sieve plate layer, described flase floor is provided with large through-hole, and described the 3rd layer is provided with little sieve aperture for the sieve plate layer, is provided with the stainless steel screen pack below described the 3rd layer of sieve plate layer.

As optimization, the aperture of described large through-hole is greater than the aperture of described little sieve aperture.

Beneficial effect: the PVC filter good corrosion resistance that the utility model provides, filter large solid impurity from flase floor first when using, then mix at the further solid-liquid of middle cavity layer, help the dispersion of the solid impurity that filters down, and then filter down in the little sieve aperture through the sieve plate layer, further filter good filtration effect finally by crossing screen pack.
