Multi-layer composite ceramic filter plate with double water channels and preparation method of multi-layer composite ceramic filter plate

Abstract

The invention relates to a multi-layer composite ceramic filter plate with double water channels and a preparation method of the multi-layer composite ceramic filter plate, and belongs to the technical field of ceramic filter plates. The multi-layer composite ceramic filter plate comprises a base plate and drain pipes, two positioning seats are arranged on end portions of the base plate, epoxy sealant layers are arranged on sides of the base plate and the positioning seats, the base plate comprises seven layers of structures including a filtering layer A, a filtering layer B, a water channel layer, a filtering layer C, another water channel layer, another filtering layer B and another filtering layer A, the seven layers of structures are laminated successively and are shaped by pressure sintering in one step, each of the water channels comprises a plurality of support units, a gap allowing flowing of water is formed between every two adjacent support unit, the water channel layers arecommunicated with the filtering layers C and the filtering layers B, and orifices of the drain pipes are communicated with the filtering layers C and the water channel layers at the same time. The multi-layer composite ceramic filter plate with the double water channels has the advantages that strength is guaranteed while water channel spaces are enlarged, apparent porosity is increased, blockingprobability is decreased, cleaning is simple, filtering efficiency and filtering effect are improved, and service life is prolonged.

AI Technical Summary

Benefits of technology

This new design uses three different types of filters - called 7-layers or simply five layers – arranged between an upper part made up from multiple small parts like metal plates and supporting elements such as ceramics. These filters help prevent clogging caused by particles entering through certain openings inside them. They also increase their lifespan because they use less material than regular ones for every other component within the system. Overall this innovative technology enhances filtering performance without increasing pressure drop across these components overcomes issues associated with traditional methods involving large amounts of solid wastes generated during manufacturing processes.

Problems solved by technology

This patented technical problem addressed in this patents relates to finding ways to improve the performance and lifespan (lifetime) of ceramsite filter plugs made from conventional methods without compromising their properties like durability.
