Abstract
Description
Technical Field
[0001] This utility model relates to the field of explosives production technology, and in particular to a grinding device for producing emulsion explosive raw materials. Background Technology
[0002] The purpose of grinding emulsion explosive raw materials is to refine the raw materials to a certain particle size and mix them evenly to meet the needs of subsequent processing and use. In explosive manufacturing, the fineness of the raw materials has an important impact on the performance of the explosives. Grinding is usually carried out using equipment such as ball mills, and can be divided into two methods: dry grinding and wet grinding. Dry grinding involves grinding the raw materials directly, while wet grinding involves adding an appropriate amount of liquid, such as alcohol or water, during the grinding process to form a moist slurry, which helps to refine and mix the raw materials.
[0003] Currently, traditional grinding devices cannot directly adjust the spacing between grinding rollers during use. When fineness control is required, the grinding rollers need to be replaced manually, which is very troublesome. After grinding, some raw materials are in powder form and may be adsorbed on the side wall of the discharge pipe of the grinding device, which requires manual collection. Otherwise, they may mix with the raw materials later, causing raw material contamination. Utility Model Content

The rotating shaft 13 and the grinding roller 29 are fixedly connected. The grinding box 3 is equipped with a power structure for controlling the rotation of the rotating shaft 13. The power structure includes a control motor 5 fixedly installed on the side wall of the grinding box 3. A drive shaft 6 is fixedly installed at the output end of the control motor 5. A support plate 7 is fixedly connected to the side wall of the grinding box 3. A rotating shaft 8 is rotatably connected to the side wall of the support plate 7. A bevel gear 9 is fixedly sleeved on the outer side of both the drive shaft 6 and the rotating shaft 8. The grinding box 3 is slidably connected to two connecting plates 10 on its upper side. The side walls of the two connecting plates 10 are rotatably connected to a telescopic shaft 11. The telescopic shaft 11 is composed of multiple shafts and has a telescopic effect. It does not affect its own rotation when telescopically extending or retracting. The telescopic shaft 11 and the outer side of the rotating shaft 8 are both fixedly sleeved with bevel gears 12, and the bevel gears 12 mesh with each other. The side wall of the grinding box 3 is slidably sleeved with two rotating shafts 13.

[0028] In this invention, firstly, the operator opens the grinding box 3 and adds raw materials. By turning on the control motor 5, the motor drives the drive shaft 6 to rotate. The drive shaft 6, through a bevel gear 9, drives the rotating shaft 8 to rotate. The rotating shaft 8, through a bevel gear 12, drives the telescopic shaft 11 to rotate. The telescopic shaft 11, through a bevel gear 14, drives the rotating shaft 13 to rotate. This causes the rotating shaft 13 to rotate the grinding roller 29, thus grinding the raw materials. To control the fineness of the grinding, a sliding rotating shaft 25 is used, causing the locking block 26 on the outside of the rotating shaft 25 to engage with the recess of the rotating shaft 16. This causes the rotating shaft 8 to rotate the rotating shaft 16. The rotating shaft 16, through a spur gear 17, drives the spur racks 18 on both sides to move. The movement of the spur racks 18 causes the rotating shaft 13 to move, which in turn moves the grinding roller 29, thus completing the grinding of the grinding roller 29. The gap adjustment between the 9 rollers allows for easy adjustment of the spacing between the grinding rollers 29 during use, eliminating the need for manual replacement of the grinding rollers 29 to adjust the grinding fineness. After grinding, the hydraulic rod 30 drives the telescopic plate 31 to move, allowing the raw material powder in the grinding box 3 to enter the collection box 27 through the discharge pipe 4. During collection, the drive shaft 6 drives the rotating shaft 19 to rotate through the bevel gear 20. The rotating shaft 19 drives the cleaning rod 23 to rotate through the spur gear 21 and the gear ring 22. The rotation of the cleaning rod 23 drives multiple sets of cleaning brushes 24 on the side wall to clean the side wall of the discharge pipe 4, preventing powdery raw materials from adhering to the side wall of the discharge pipe 4 and affecting the subsequent work process. It also eliminates the need for manual collection of raw material powder from the side wall of the discharge pipe 4.
