Abstract

The present invention is improved filter plate for solid-liquid separating drier. The improved filter plate is hydrophilic microporous plastic plate with average pore size of 0.2-1.5 microns, and forms the sucking filter element walls. It is superior to available ceramic plate, and has pore opening rate of about 60 %, 20-30 % higher production capacity, high toughness, high impact resistance, and acid and base resistance.

Description

technical field

[0001] The invention is an improvement to a filter plate used in a solid-liquid separation suction drying device, in particular to a hollow suction microporous filter element made of plastic. Background technique

[0002] The hollow suction microporous filter element is a high-efficiency solid-liquid separation element that applies the capillary principle. Under the water-wet state, the capillary effect allows water to pass through, but gas and particles cannot pass through, especially for solid-liquid separation in concentrate dehydration and drying. There are many applications. Since the invention of the filter element, ceramic hollow filter plates with micropores (such as 0.5-3.0 μm) on the filter wall have been used. Although there have been many inventions and improvements during the period, none of them has been separated from the ceramic material. Microporous ceramics have actually become concentrates. The only filter element for hollow suction dehydr...
