Technical Field

[0001] The utility model belongs to the technical field of rare earth preparation equipment, and in particular relates to a crushing machine for rare earth electrolysis molten salt waste slag. Background Art

[0002] At present, the main methods of rare earth metal smelting are metal thermal reduction and molten salt electrolysis. The total yield of molten salt electrolysis is about 92%. The waste molten salt produced in the molten salt electrolysis process is about 5% or more. The rare earth content of these waste molten salts is about 20%-70%. If these rare earth molten salt wastes are fully recycled, the rare earth loss rate can be significantly reduced, production costs can be reduced, and economic benefits can be improved.

[0003] At present, in the conventional rare earth molten salt waste recycling process, the rare earth is separated from other substances by washing, filtering and extraction after roasting in order to improve the purity. However, the alkali melt after conventional roasting is dense and hard and not easy to crush. In order to ensure the separation of rare earth and other substances at the back end, the crushing particle size is required to be high, and high-energy consumption crushing treatment is required. The existing conventional crushing equipment cannot ensure the consistency of the crushed particle size, and will also compact the material. When crushing larger particles, the particle alkali melt and torque cannot be evenly distributed, which affects the motor performance and even causes equipment damage. Utility Model Content

[0004] In order to solve the above-mentioned technical problems, the purpose of the utility model is to provide a rare earth electrolytic molten salt waste slag crushing machine to solve the technical defects of the existing conventional crushing equipment that cannot ensure the consistency of particle size during the crushing process, and at the same time, the uneven particle matter and torque when crushing larger particles affect the motor performance and damage the equipment.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a rare earth electrolysis molten salt waste slag crushing machine, comprising a leg frame, a mounting ring is fixedly installed on the upper surface of the leg frame, a rare earth grinding cylinder is detachably installed in the mounting ring, a connecting frame is fixedly installed on the outer surface of the mounting ring, a mounting plate is fixedly installed on the other end of the connecting frame, a rare earth electrolysis molten salt waste slag crushing assembly is fixedly installed on the upper surface of the mounting plate, and the rare earth electrolysis molten salt waste slag crushing assembly is rotatably installed in the rare earth grinding cylinder.

[0006] As a preferred solution of the utility model, a plug-in block is fixedly installed on the outer surface of the rare earth grinding cylinder, and the plug-in block is plugged into the plug-in groove. The plug-in groove is opened in the inner ring of the mounting ring, and the bolt thread passes through the mounting ring and the plug-in block.

[0007] As a preferred embodiment of the utility model, the rare earth electrolysis molten salt waste slag crushing assembly includes a motor, which is fixedly mounted on the upper surface of the mounting plate. The motor output shaft passes through the lower surface of the mounting plate, and a connecting column is fixedly mounted on the end. A docking column is removably mounted on the lower surface of the connecting column, and a crushing cone is fixedly mounted on the lower surface of the docking column.

[0008] As a further preferred embodiment of the present invention, the rolling cone and the rare earth grinding cylinder are both in a stepped tapered shape.

[0009] As a preferred solution of the utility model, the rolling cone is rotatably installed in the rare earth grinding cylinder, and each step of the rare earth grinding cylinder has a different spacing, and the spacing between each step is gradually reduced.

[0010] As a preferred solution of the utility model, each step portion of the rolling cone and the rare earth grinding cylinder is fixedly mounted with grinding teeth.

[0011] Compared with the prior art, the rare earth electrolysis molten salt waste slag crushing machine provided by the utility model has the following advantages:

[0012] Beneficial effects:

[0013] 1. When the rare earth electrolysis molten salt waste slag is crushed, the rare earth electrolysis molten salt waste slag can be poured into the rare earth grinding cylinder, and the rare earth electrolysis molten salt waste slag crushing and crushing assembly is started to rotate in the rare earth grinding cylinder. The rare earth electrolysis molten salt waste slag is crushed into multiple pieces by the rotation force of the rare earth electrolysis molten salt waste slag crushing and crushing assembly, and the rare earth electrolysis molten salt waste slag is distributed to other parts of the rare earth grinding cylinder through the rotation force, so as to ensure that the torque is evenly distributed everywhere during the rare earth crushing process, thereby reducing the burden on the motor.

[0014] The continuously rotating rare earth electrolysis molten salt waste slag crushing and crushing assembly will drive the rare earth electrolysis molten salt waste slag to continuously rotate and crush in the rare earth grinding cylinder until its particle size can pass through the current spacing and enter the step layer with a smaller spacing to continue crushing. After the rare earth electrolysis molten salt waste slag is crushed to the standard particle size, it falls out from the lower surface of the rare earth grinding cylinder, making the crushed rare earth electrolysis molten salt waste slag particle size uniform, making it more sufficient to wash, filter and separate at the rear end, thereby increasing work efficiency.

[0015] 2. After pouring the rare earth electrolytic molten salt waste slag into the rare earth grinding cylinder, the motor can be started to drive the rolling cone to rotate in the rare earth grinding cylinder. The grinding teeth are arranged on the surface of the rolling cone and the inner surface of the rare earth grinding cylinder. The continuously rotating rolling cone will drive the rare earth to be continuously rolled by the grinding teeth between the rare earth grinding cylinder and the rolling cone to the standard particle size, and then it will fall out from the lower surface of the rare earth grinding cylinder. The rare earth electrolytic molten salt waste slag can be rolled in multiple steps by the stepped rare earth grinding cylinder and the rolling cone. BRIEF DESCRIPTION OF THE DRAWINGS
