Vacuum ceramic filter plate and manufacture method thereof

Abstract

The invention relates to a vacuum ceramic filter plate and a manufacture method thereof. The vacuum ceramic filter plate is structurally characterized in that a film hole is formed on the film surface of the vacuum ceramic filter plate, the film hole is in a step shape and is in the reverse conical shape, and the thickness of the film surface is between 0.2 and 0.7 mm. The manufacture method comprises the following steps: base plate bonding agent preparation; material mixing, forming and drying; primary sintering, grinding processing and soaking flushing; staged film spraying process; secondary drying; secondary sintering and gluing; assembly hole manufacture and installation; edge sealing and painting; and checking and storage. The invention has the advantages that the procurement cost of users is saved, the frequency and times for replacing the filter plate are reduced, the shutdown time loss caused by unexpected plate bursting in the production is reduced, the production efficiency is improved, the generation of solid waste materials is reduced, and the invention has good environment protection valve and good social economic benefits. The integral structural intensity (in a wet state) reaches the effect that the plate bursting does not occur in the 0.6 MPa air compression test, and the abrasion resistance intensity is more than one time higher than that of a conventional film surface. The rejection rate of the filter plate is reduced by more than 50 percent, and the generation of solid waste materials is reduced.

Description

technical field [0001] The invention relates to a vacuum ceramic filter plate for a ceramic filter and a manufacturing method thereof, belonging to the technical field of ceramic filter accessories. Background technique [0002] The filter is a device that uses a porous filter medium to intercept solid particles in a mixture of liquid and solid particles to achieve solid-liquid separation. Filters are widely used in chemical industry, petroleum, pharmaceutical, light industry, food, mineral processing, coal and water treatment and other departments. The filter plate is the core component of the ceramic filter. The inorganic membrane hole firing process is adopted, and the capillary principle is used to form a vacuum in the plate, which can effectively separate and extract the water in the slurry, and trap the solid matter in the slurry on the filter plate, and then scrape it off with a scraper. At present, there are no international standards and national industry standard...

AI Technical Summary

Problems solved by technology

At present, there are no international standards and national industry standards for filter plates. There are only industry standards for filter machines in China to regulate the quality of filter plates.

However, the theoretical research on the design and development of the filter plate is relatively lagging behind, making it difficult for the performance and actual use effect of the filter plate to meet the increasingly high requirements of customers, such as: the use effect and service life of the filter plate

In the past mine beneficiation process, multi-type filtration process was mostly used. Due to the high energy consumption, low output, large loss of water resources, large tailings moisture, and large area occupation, this process has caused hidden safety hazards in storage.
