Description

Technical Field

[0001] The invention belongs to the technical field of antimony smelting, and in particular relates to a device for kneading and breaking up antimony particles. Background Art

[0002] After the smelting of metal antimony is completed, the traditional method is to introduce the antimony melt into the ingot casting machine for ingot casting. The disadvantages of this method are: on the one hand, when downstream enterprises carry out deep processing of the produced antimony ingots, they need to melt the antimony ingots with relatively large volume and weight again, which is not conducive to improving production efficiency, nor is it conducive to automation and intelligent control in the production process. On the other hand, during the ingot casting process, due to the strong adhesion of antimony, the metal antimony block after ingot casting is difficult to demold from the ingot mold. Finally, only a movable ejector plate can be installed at the bottom of the ingot mold, and the movable ejector plate can be knocked with a knocking mechanism, so that the metal antimony can be demolded from the ingot mold. During the knocking process, the ingot mold will be subjected to a certain knocking force. Long-term knocking may cause a certain deformation of the ingot mold and affect the molding quality of the antimony ingot (unable to achieve the required shape); in addition, the knocking process will produce relatively large noise pollution.

[0003] At present, there is a method of granulating antimony melt by water extraction. The water extraction method is used to process the antimony melt into antimony particles, which not only improves the production efficiency of antimony material deep processing, but also facilitates the automation and intelligent control of antimony material deep processing. Moreover, the antimony ingot demoulding process is not required during the molding process, which effectively avoids the disadvantages of the antimony ingot demoulding process. However, during the process of granulating antimony melt by water extraction, the antimony particles are easy to stick together and need to be further dispersed. The current dispersion equipment is easy to damage the antimony particles. Summary of the invention

[0005] To achieve the above object, the present invention adopts the following technical solutions:

[0006] A device for kneading and breaking up antimony particles comprises a frame, a breaking up drum, a breaking up screen, a flexible protrusion component and a motor; the breaking up drum is rotatably mounted on the frame, the breaking up screen is mounted below the breaking up drum, the motor is used to drive the breaking up drum to rotate, a plurality of circles of first flexible protrusions are evenly arranged on the outer surface of the breaking up drum, a plurality of groups of second flexible protrusions arranged in an arc shape and facing the breaking up drum are evenly arranged on the surface of the breaking up screen, and the second flexible protrusions arranged in an arc shape are staggered with the first flexible protrusions on the outer surface of the breaking up drum.
