Description

Technical Field

[0001] The utility model relates to the field of gypsum processing feeding devices, in particular to a spiral propulsion feeding device for gypsum crushing. Background Art

[0002] Gypsum has many uses in the medical field. For example, patients with fractures use plaster to maintain the stability of the fracture, facilitate rapid healing of the fracture, and prevent secondary injuries. Gypsum blocks can also be crushed and ground for recycling after use.

[0003] After searching, it was found that the publication number is CN215507192U, and the name is a spiral propulsion feeding device for gypsum block crushing. The application proposes that most of the existing gypsum block crushers put the gypsum blocks into a mixer, and crush them by rotating the blades of the mixer, which has a relatively low efficiency, and the gypsum blocks after crushing are still large, and the sizes of the gypsum blocks are different. The gypsum blocks are gradually lowered in the inverted conical barrel by the driving force of the inverted conical screw, and in the process of falling, due to the smaller and smaller space, they are squeezed by the inverted conical screw and the inner wall of the inverted conical barrel, and finally the gypsum blocks are crushed under the action of the squeezing force, and the crushing efficiency is high. The gypsum blocks are squeezed by the filter screen at the discharge port and crushed into fine particles. The size of the gypsum blocks after crushing is relatively uniform, which is convenient for further grinding. However, when the application is in use, the screen plate controls the target particle size of the gypsum. If the aperture of the screen plate is small, the risk of clogging is high. The pressure on the screen plate and the inverted conical screw is huge, resulting in serious wear and compression deformation, requiring a higher power motor drive, which not only affects the structural stability and service life, but also is not energy-efficient. At the same time, if the aperture of the screen plate is large, it is difficult to meet the recycling particle size requirements and is difficult to recycle. Further improvements can be made. At the same time, the application is driven by a steel belt. When the rotation resistance of the inverted conical screw becomes larger, the steel belt is prone to slipping, which also affects normal work. When the gypsum powder and spray water fall, they will lubricate the surface of the steel belt, further aggravating the slipping phenomenon. Further improvements can be made.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content
