Technical Field

[0001] The utility model relates to the field of casting material production, in particular to a feeding device for producing high temperature resistant casting material. Background Art

[0002] Castable, also known as refractory castable, is a granular and powdered material made of refractory materials with a certain amount of binder added. It has high fluidity and is an amorphous refractory material formed by pouring. Compared with other amorphous refractory materials, it has higher binder and moisture content and better fluidity. Therefore, castable has a wide range of applications. The material and binder used can be selected according to the conditions of use. It can be directly cast into a lining for use, or made into prefabricated blocks by pouring or vibrating.

[0003] At present, when the castable is produced, it is necessary to load the castable, and the loading position of the castable is relatively high. In addition, since the castable itself contains dust, adding it directly from a high place can easily cause it to diffuse in the production equipment and then diffuse into the air, which not only causes a waste of raw materials, but also affects the surrounding environment.

[0004] Therefore, it is necessary to invent a feeding device for high temperature resistant castable production to solve the above problems. Utility Model Content

[0010] Technical effects and advantages of the utility model:

[0011] The castable is fed by a spiral feeding pipe and discharged through a discharge pipe. The castable in the discharge pipe enters an inclined particle discharge pipe, and the granular material and powder are screened by a screen at the bottom of the inclined particle discharge pipe. During the rolling of the castable, a dust exhaust fan is used to absorb dust, and the dust generated by the rolling of the castable is sucked into a dust hopper and then discharged through the dust exhaust pipe, thereby collecting the dust in a centralized manner, and the granular material, powder and dust in the castable can be conveniently treated separately, thereby avoiding the problem of easy diffusion of powder and dust.
