Description

Technical Field

[0001] The utility model relates to the technical field of ceramic drying, in particular to a dust removal device for ceramic drying. Background Art

[0002] Ceramics is a general term for pottery and porcelain. Common ceramic materials include clay, alumina, kaolin, etc. Ceramic materials are generally hard but have poor plasticity. In the processing of ceramic products, ceramic products are usually dried after initial forming. One reason is to reduce the moisture in the semi-finished products to facilitate subsequent sintering; secondly, preliminary drying can be used to detect the degree of forming of ceramic products and whether there are cracks, so that unqualified products can be removed as soon as possible. In the process of drying ceramic products, as the fractions continue to evaporate, some floating dust will be generated. If it is not cleaned in time, it will adhere to the surface of the ceramic and affect the overall quality. Therefore, it is necessary to use an external dust removal device for dust removal. However, there are still some problems with the existing devices when they are used:

[0003] The dust removal device is easy to clog. When the existing dust removal device filters the air dust in the ceramic drying, it uses a filter-like structure for interception and filtration. However, the dust will clog the mesh of the filter due to long-term filtration, which will greatly reduce the subsequent filtration efficiency after long-term dust removal and filtration, and the internal disassembly and cleaning are cumbersome.
