Abstract

The invention relates to the field of filtration separation equipment with a closed container filled with a filtration material, in particular to a self-cleaning spiral extrusion filter and a use method thereof. The self-cleaning spiral extrusion filter comprises a vertical cylinder (1) vertically arranged. The self-cleaning spiral extrusion filter is characterized by further comprising a vertical shaft (21), vertical spiral blades (22), a filter net (23) and a motor (3), wherein the vertical shaft (21) is vertically arranged in the vertical cylinder (1), and an output shaft of the motor (3) is connected with the vertical shaft (21) through a driving mechanism; the vertical spiral blades (22) are fixed to the vertical shaft (21), and the filter net (23) in a cylindrical shape is arranged outside the vertical spiral blades (22) in a sleeving mode. The use method of the self-cleaning spiral extrusion filter is characterized by comprising the following steps of a, start and b, filtration. The self-cleaning spiral extrusion filter and the use method have the advantages of being high in filtration efficiency, little in material loss, long in service life, low in production cost and friendly to the environment.

Description

technical field [0001] The invention relates to the field of filtration and separation equipment equipped with filter materials in a closed container, in particular to a self-cleaning screw extrusion filter and its application method. Background technique [0002] Liquid material such as emulsion is a kind of dispersion system, which is widely used in production. The particle size of the dispersoid in the emulsion is larger than that of the solution and colloid. During the preparation process of the emulsion, impurities with large particles are easily mixed in the dispersant, which will affect the use of the emulsion, and must be filtered in time and thoroughly. But at present, there is no high-efficiency filtration method for liquid materials, especially high-viscosity liquid materials. At present, the filter of liquid materials mostly adopts bag filter, so that the liquid material passes through the bag filter, and the large particles of impurities are separated from the...
