Multilayer continuous pressed-drying filtering machine and filtering method thereof

Abstract

The invention provides a multilayer continuous pressed-drying filtering machine and a filtering method thereof. The filtering machine comprises a filtering machine body, filtering areas formed by filtering assemblies are arranged in the filtering machine, the filtering machine body sequentially comprises an upper layer machine body and a lower layer machine body separated by a bottom cover of theupper machine body from top to bottom, the filtering areas formed by the filtering assemblies are respectively arranged in the upper layer machine body and the lower layer machine body; an upper layerfiltering area and a middle layer filtering area are arranged in the upper layer machine body, a lower layer filtering area is arranged in the lower layer machine body; the bottom part of the upper layer machine body is communicated with the interior of the lower layer machine body through a valve, the bottom part of the lower layer machine body is provided with a filtering machine lower cover, filtered liquid outlets of the upper layer filtering area, the middle layer filtering area and the lower layer filtering area are communicated with a discharge opening through discharging hoses. The multilayer continuous pressure-drying filtering machine has the beneficial effects that the filtering machine is subjected to layered processing, filtering of each machine body layer does not interferewith each other, procedures of continuous filtering and pressed-drying is complete, and the filtering efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of microporous filtration, and in particular relates to a multi-layer continuous pressure-drying filter and a filtering method thereof. Background technique [0002] The application of microporous filtration technology is becoming more and more extensive. The top of the existing microporous filter is provided with a flower plate, and the filter element is vertically arranged on the flower plate, and the material is filtered through the filter element and then passed through the filter in the flower plate. The liquid channel flows out. Existing filters are generally single-tube filters, which are cleaned up after the filter is completed, and then continue to filter the solution in the next round, which cannot complete continuous filtration, and the filter efficiency is not high. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the invention provides a multi-layer cont...
