Raw material preparation device for production of refractory material

Abstract

The invention relates to a raw material preparation device for production of a refractory material. The device comprises a pretreatment box, the bottom of the pretreatment box is provided with a support, the lower part of an inner cavity of the pretreatment box is provided with a discharge hopper, the narrow opening end of the discharge hopper is connected with a discharge inclined pipe, and the lower part of the inner cavity of the pretreatment box is provided with a multifunctional stirring rod; a stirring motor is arranged on the support, and the bottom end of the multifunctional stirring rod penetrates the bottom wall of the discharge inclined pipe to be connected to the output shaft end of the stirring motor; and the top end of the pretreatment box is provided with a feed hopper, theupper part of the inner cavity of the pretreatment box is provided with a crushing mechanism, and an inclined filter net is arranged at the lower side of the crushing mechanism. According to the device, through the technical means that a material return mechanism, the multifunctional stirring rod and a vibration discharge mechanism are arranged, the problems that material blockage easily occur because raw materials that are not sufficiently crushed cannot directly return to a crushing roller for secondary crushing, and multiple crushed raw materials cannot be fully mixed in the prior art are solved.

Description

technical field [0001] The invention relates to the technical field of refractory material production, in particular to a raw material preparation device for refractory material production. Background technique [0002] A class of inorganic non-metallic materials with a refractoriness not lower than 1580°C. Refractoriness refers to the Celsius temperature at which a refractory conical sample can resist high temperature without softening and melting without load. However, it is not possible to fully describe refractory materials only by the definition of refractoriness, and 1580°C is not absolute. It is now defined as a material whose physical and chemical properties allow it to be used in a high temperature environment is called a refractory material. Refractory materials are widely used in metallurgy, chemical industry, petroleum, machinery manufacturing, silicate, power and other industrial fields, and are used in the largest amount in the metallurgical industry, account...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the deficiencies of the prior art by means of technical means such as the return mechanism, the multifunctional stirring rod and the vibrating feeding mechanism, etc. It cannot be directly returned between the crushing rollers for secondary crushing. It needs manual feeding and returning of materials to achieve secondary crushing, which consumes a lot of manpower and material resources. Secondly, this structure cannot fully mix the various crushed raw materials in and out. The raw material processing effect is poor, and finally, the device is very prone to the problem of feeding blockage, and the technical problem of "refractory materials affecting production efficiency"
