Mixing device

Abstract

The embodiment of the invention discloses a mixing device. The mixing device comprises a shell, a mixing part and a screening part, wherein a cavity is formed in the shell, the mixing part and the screening part are sequentially arranged in the cavity in the feeding direction, and the mixing part communicates with a feeding inlet; the mixing part at least comprises an extrusion ring and a stirringstructure, wherein the extrusion ring is arranged in the mode of being protruded from the inner side wall of the shell, and at least part of the stirring structure is located in a mixing cavity defined by the extrusion ring; and the screening part at least comprises an extruding block arranged in the cavity, part of the upper surface of the extruding block and part of the lower surface of the extrusion ring are matched to form an overflowing channel, wherein one end of the overflowing channel communicates with the mixing cavity, and the other end of the overflowing channel communicates with adischarging outlet. The extruding block and the extrusion ring are matched to form the overflowing channel, thus mixed raw materials can be further screened through the overflowing channel to stop passage of the bulk raw materials, the stability of the mixed raw materials is improved, and the problem of chipping halt is avoided.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of material mixing, and in particular to a material mixing device. Background technique [0002] The mixer is a very important production equipment in the gypsum board production line. As the source of the entire production line, its stability in operation will directly affect the stability of the entire production line. [0003] However, in the actual use process, due to the physical and chemical properties of the raw materials of gypsum board or the influence of storage conditions, the raw materials are likely to appear blocky, and the blocky raw materials (especially large blocks) are easy to mix during the mixing process. There are problems such as block falling, and if there are many block falling times in the mixing equipment, it will cause the entire production line to stop many times in the continuous production process, which will bring great losses to the production proces...

[0003] However, in the actual use process, due to the physical and chemical properties of the raw materials of gypsum board or the influence of storage conditions, the raw materials are likely to appear blocky, and the blocky raw materials (especially large blocks) are easy to mix during the mixing process. There are problems such as block falling, and if there are many block falling times in the mixing equipment, it will cause the entire production line to stop many times in the continuous production process, which will bring great losses to the production process and also cause product damage. quality instability
