[0001] The utility model relates to the technical field of crushing devices, in particular to a raw material crushing device for the production of high-purity barium carbonate. Background Technique

[0002] Barium carbonate is a highly toxic chemical. It is in the form of hexagonal fine crystals or white powder. Barium carbonate is insoluble in water and soluble in acids. Barium carbonate has a wide range of uses. It is mainly used in the electronics, instrumentation, and metallurgical industries, for preparing fireworks, making signal flares, ceramic coatings, as an auxiliary material for making optical glass, and also used as a rodenticide, water clarifier, and filler.

[0003] At present, during the processing of raw materials for barium carbonate production, when processing raw materials with a relatively large volume, the raw materials cannot be crushed hierarchically, which is not convenient for raw material crushing, and the working efficiency is low. Moreover, the traditional crushing device is not convenient for cleaning and maintaining the inside of the crushing device after being used for a period of time. Therefore, a raw material crushing device for the production of high-purity barium carbonate is proposed to solve the above problems. Content of the Utility Model

[0031] During use, by sliding the sliding plate 6 outwards to one side inside the chute groove 5, the inside of the first crushing box 1 can be cleaned. Then, the latch 21 is flipped upwards so that one end of it is disengaged from the clamping seat 20. Then, the moving frame 14 is pushed to one side. Since the universal wheels 15 are arranged at the bottom of the moving frame 14, the transmission cylinder 3, the feeding hopper 12 and the hatch 19 can be driven to move to one side. While the hatch 19 is flipped to one side, one end of the L-shaped connecting rod 18 is driven to rotate on the surface of the connecting frame 17, and then the second crushing box 2 can be opened, avoiding the problem of inconvenient cleaning and maintenance of the inside of the crushing device.

[0032] Please refer to Figure 2 , a crushing roller 7 is arranged inside the first crushing box 1. There are multiple groups of crushing rollers 7. One end of a group of crushing rollers 7 is connected to a transmission wheel 10. The transmission wheel 10 is arranged outside the first crushing box 1.

Through the rotation of the transmission wheel 10 and the driven wheel 8, two groups of crushing rollers 7 are driven to rotate towards each other, and then the raw materials inside the first crushing box 1 are preliminarily crushed.

[0033] Please refer to Figure 6, inside the second crushing box 2, there is a crushing cylinder 24. Multiple feeding holes 25 are arranged on the surface at the lower end of the crushing cylinder 24. The arranged crushing cylinder 24 facilitates the crushing of raw materials.

[0034] Please refer to Figure 3 , 6 , a second rotating motor 11 is installed at the rear end of the second crushing box 2. The output end of the second rotating motor 11 is connected to a rotating shaft 23. The rotating shaft 23 passes through the second crushing box 2 and extends into its interior. Multiple extrusion plates 22 are connected to the surface of the rotating shaft 23. By arranging the second rotating motor 11 to drive the rotation of the rotating shaft 23, the rotation of the rotating shaft 23 drives the rotation of multiple extrusion plates 22. Through the rotation of the extrusion plates 22, the raw materials are extruded and rubbed on the feeding holes 25 for secondary crushing.

[0035] Please refer to Figure 3 , 4 , one end of the transmission cylinder 3 is connected to the center of the hatch 19. A auger 16 is arranged inside the transmission cylinder 3.

By arranging the servo motor 13 to drive the rotation of the auger 16, the raw materials in the transmission cylinder 3 can be conveyed into the second crushing box 2.

[0036] Please refer to Figure 6 , a discharge port 26 is arranged at the bottom of the second crushing box 2. The discharge port 26 penetrates the inner side of the second crushing box 2. Through the arranged discharge port 26, it is convenient to discharge the crushed raw materials.

[0037] Please refer to Figure 1 , 3 , a feeding hopper 12 is arranged at the lower end of the first crushing box 1. The lower end of the feeding hopper 12 is fixedly installed on the surface at the upper end of the transmission cylinder 3. Through the arranged feeding hopper 12, it is convenient for the preliminarily crushed raw materials to fall into the transmission cylinder 3 for transmission.

[0038] Please refer to Figure 1 , a support frame 4 is arranged between the upper ends of the second crushing box 2 and the feeding hopper 12. One end of the support frame 4 is fixedly installed on the upper surface of the second crushing box 2. A through groove is arranged on the surface of the first crushing box 1, and the first crushing box 1 is fixedly installed inside the through groove. Through the arranged support frame 4, it plays a role in supporting the first crushing box 1.

[0039] Working principle: The utility model is a raw material crushing device for the production of high-purity barium carbonate. First, the raw materials are put into the first crushing box 1, and then the slide plate 6 is pushed to slide in the chute 5, so that the first crushing box 1 can be covered to prevent the raw materials from splashing out during crushing. Then, the first rotating motor 9 is started to drive the driving wheel 10 to rotate. The rotation of the driving wheel 10 drives the engaged driven wheel 8 to rotate. The rotation of the driving wheel 10 and the driven wheel 8 drives the two groups of crushing rollers 7 to rotate towards each other, thereby initially crushing the raw materials in the first crushing box 1. The crushed raw materials fall into the transmission cylinder 3 through the feed hopper 12. Then, the servo motor 13 is started to drive the auger 16 to rotate, and the initially crushed raw materials are transported into the crushing cylinder 24. Then, the second rotating motor 11 is started to drive the rotating shaft 23 to rotate. The rotation of the rotating shaft 23 drives the multiple groups of pressing plates 22 to rotate. The rotation of the pressing plates 22 enables them to press and rub the raw materials on the feed holes 25 for secondary crushing. The crushed raw materials are discharged through the feed holes 25 and the discharge port 26.

[0040] When it is necessary to clean and maintain the crushing device, by sliding the slide plate 6 outwards on one side in the chute 5, the inside of the first crushing box 1 can be cleaned. Then, the latch 21 is flipped upwards so that one end of it disengages from the socket 20. Then, the moving frame 14 is pushed to one side. Since the universal wheels 15 are provided at the bottom of the moving frame 14, the transmission cylinder 3, the feed hopper 12 and the hatch 19 can be driven to move to one side. While the hatch 19 flips to one side, one end of the L-shaped connecting rod 18 is driven to rotate on the surface of the connecting frame 17, and thus the second crushing box 2 can be opened to facilitate the cleaning of its inside.
