Heat preservation powder negative pressure recycling system in production of refractory material by using fusion casting method

Abstract

The invention relates to the technical field of refractory material production, and in particular relates to a heat preservation powder recycling system in production of a refractory material by using a fusion casting method. The system comprises a material purification system, a negative pressure vacuum system and a material recycling system, wherein a suction nozzle (1) and a soft connecting tube (2) are positioned inside a material tank (3) in the material purification system; the suction nozzle (1) is connected with a dust collector (5) through the soft connecting tube (2) and a transmission pipeline (4) in sequence; a vacuum pump (7) is connected with the dust collector (5) through a draft tube (6) in the negative pressure vacuum system; in the material recycling system, the upper part of a middle material cabin (10) is connected with the dust collector (5), and the lower part of the middle material cabin is connected with a material warehouse (11); a conveyer (12) is arranged at the bottom of the material warehouse (11) and is used for conveying a material to a material tank (13). The heat preservation powder negative pressure recycling system provided by the invention is thorough in heat preservation powder recycling, high in efficiency and free of dust pollution and simple and convenient to operate, and has good economic and environment-friendly benefits.

Description

technical field [0001] The invention belongs to the technical field of refractory material production, and in particular relates to a thermal insulation powder recovery system in the process of producing refractory material by melting and casting. Background technique [0002] Refractory materials, especially in the process of producing refractory materials by melting and casting methods, such as the insulation powder used in the production process of melting and casting corundum bricks, due to the fine particle size, the particle size is about 60 microns, and it is easy to generate a lot of dust in the process of recycling and purification. It will cause great harm to the health of the operating workers, and it will also easily cause environmental pollution, and a large amount of thermal insulation powder will be lost additionally. And still lack comparatively effective thermal insulation powder recovery system in the prior art. Contents of the invention [0003] The p...
