Efficient raw material mixing device for production of heat-insulating refractory bricks

Abstract

The invention relates to the technical field of refractory brick production, and discloses an efficient raw material mixing device for heat-insulating refractory brick production, a feeding mechanism is fixedly connected to the upper part of a mixing box body, and a mixing pipeline is fixedly connected to the top end of the inner side of the mixing box body; a transmission main shaft is rotationally connected to the position, located in the middle, of the inner side of the material mixing pipeline, a material mixing paddle is fixed to the outer side of the transmission main shaft, and spiral conveying paddles are symmetrically connected to the positions, located at the bottom end, of the inner side of the material mixing box body. By means of the feeding mechanism capable of automatically sealing the end opening of the feeding pipe, the feeding opening of the mixing device can be sealed, then the situation that dust is scattered outwards in the mixing process of refractory brick raw materials is avoided, in the mixing process, the refractory brick raw materials are preliminarily stirred and mixed through a mixing paddle, and the mixing efficiency is improved. And under the secondary spiral conveying and stirring of the spiral conveying paddle, the refractory brick raw materials can be efficiently mixed.

Description

technical field [0001] The invention relates to the technical field of refractory brick production, in particular to an efficient mixing device for raw materials for the production of heat-insulating refractory bricks. Background technique [0002] Refractory bricks are refractory materials with a certain shape and size. According to the preparation process, refractory bricks can be divided into fired bricks, non-fired bricks, fused bricks (fused cast bricks), and refractory insulation bricks, which can be divided according to shape and size. For standard bricks, ordinary bricks, special bricks, etc., they can be used as high-temperature building materials and structural materials for building kilns and various thermal equipment, and can withstand various physical and chemical changes and mechanical effects at high temperatures. During the production and processing of refractory bricks, the raw materials of refractory bricks need to be mixed. [0003] However, there are som...

Problems solved by technology

[0003] However, there are some shortcomings in the raw material mixing device for refractory brick production in the market. The traditional mixing device has a single structure, and the mixing production efficiency is relatively low. In the process of mixing raw materials, the dust generated by mixing is extremely Easy to disperse, affecting the working environment of the staff
