Novel ceramic material filtering device

Abstract

The invention relates to a ceramic filtering device. The ceramic filtering device comprises a side wall and a bottom wall, the side wall comprises an inner layer, an outer layer and a middle layer located between the inner layer and the outer layer, the materials of the inner layer and the outer layer are the same, the middle layer is a foamed ceramic, the bottom wall is formed by extending the middle layer downwards, and the thickness of the bottom wall is 1 / 3-1 / 10 of the thickness of the middle layer. As the middle layer made of the foamed ceramic is arranged directly between the inner layerand the outer layer to form a heat insulation layer, a to-be-filtered material is effectively prevented from being affected by the outside environment in the filtering process. Meanwhile, the bottomwall used for filtering is formed by extending the middle layer and forms an integrated structure with the middle layer, so that part of the material is effectively prevented from leaking out from a crack formed by the bottom wall and the side wall in the long-term use process to affect the filtering effect. The inner layer and the outer layer use the same materials to effectively prevent the influence of different stresses on the middle layer in the sintering process. The thickness of the bottom wall is 1 / 3-1 / 10 of the thickness of the middle layer, so that the middle layer has an excellent heat insulation effect, and meanwhile, the filtering efficiency of the bottom wall is higher.

Description

technical field [0001] The invention relates to the technical field of ceramics, in particular to a ceramic filter device. Background technique [0002] Porous ceramic composites can be used, for example, in filtration technology, and ceramic multilayer filters can be used, for example, to separate oil-water emulsions in chip removal production, to clarify beer, to purify gases, to separate gases or to separate liquid-solid mixtures. [0003] In the prior art, the sintered and sintered container is usually re-sintered with the filterable bottom wall. Since multiple sinterings are required, the production efficiency is low. At the same time, since the sintered side wall has only a single-layer structure, the filterable The heat preservation effect of the material in the ceramic filter device is poor. For products with a large temperature influence, it may affect the product, such as taste. Contents of the invention [0004] The invention provides a ceramic filtering device...
