Description

Technical Field

[0001] This utility model relates to the field of calcium oxide production technology, and in particular to a fine grinding device for calcium oxide production. Background Technology

[0002] Calcium oxide, as an important industrial raw material, is widely used in many fields such as construction, chemical industry, and environmental protection. In the production process of calcium oxide, obtaining products with uniform particle size and meeting the required fineness is crucial to ensuring its quality and performance.

[0003] In existing technologies, most fine grinding devices for calcium oxide production lack secondary screening, which fails to effectively remove calcium oxide particles that do not meet the particle size requirements. This results in uneven particle size distribution in the product, which makes the performance of calcium oxide unstable during use, such as inconsistent reaction rates in chemical reactions, thus affecting the quality of the final product. Therefore, we propose a fine grinding device for calcium oxide production to solve this problem. Utility Model Content

[0004] The purpose of this invention is to provide a fine grinding device for calcium oxide production, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0013] In this utility model, a fine grinding device for calcium oxide production is provided.

Springs 14 and lifting rods 15 are fixedly installed on the top of each of the four sets of bottom columns 13. Top columns 16 are fixedly installed on the other side of each of the four sets of springs 14 and lifting rods 15. Fixing plates 28 are fixedly installed between two sets of top columns 16 on the same side. Screening plates 11 and 2 are fixedly installed inside the two sets of fixing plates 28. Vibration motors 17 are fixedly installed on one side of each set of fixing plates 28. One side of the material plate 18 is connected to the coarse material outlet 20, and one side of the screening plate 19 is connected to the coarse material outlet 21. Two sets of mounting plates 27 are slidably installed on the top of the bottom plate 1. A fine material collection box 24 is fixedly installed on the top of the two sets of mounting plates 27. A fine material collection box 24 is slidably installed on the top of the bottom plate 1. The same top plate 3 is fixedly installed on the top of the four sets of support columns 2. A rotating shaft 10 is rotatably installed inside the top plate 3. A connecting block 11 is fixedly installed on the outside of the rotating shaft 10. A grinding rod 12 is installed at the bottom of the connecting block 11. The same grinding table 8 is fixedly installed inside the four sets of support columns 2.

[0022] In this embodiment, a mounting bracket 6, a drive motor 4, and a housing 7 are fixedly installed on the top of the top plate 3. A rotating rod 5 is fixedly installed at the output end of the drive motor 4. A worm gear 26 is fixedly installed on the outer side of the rotating rod 5. A worm wheel 9 is fixedly installed on the top of the rotating shaft 10. The worm wheel 9 meshes with the worm gear 26. The rotating rod 5 is rotatably installed inside the mounting bracket 6. The cooperation between the grinding table 8 and the grinding rod 12 can increase the contact area and intensity of grinding, so that calcium oxide can be refined more quickly.

[0023] In this embodiment, the outer side of the rotating rod 5 is rotatably mounted inside the housing 7. The worm wheel 9, the worm 26 and one end of the rotating shaft 10 are all located inside the housing 7. The worm wheel 9 and the worm 26 have a large transmission ratio and self-locking characteristics, which can provide strong torque to the grinding table 8 and the grinding rod 12, ensuring that large resistance can be overcome when grinding calcium oxide.

[0024] In this embodiment, two sets of slide rails are fixedly installed on the top of the top plate 3, and the fine material collection box 24 is slidably installed on the slide rails. A handle 25 is fixedly installed on one side of the fine material collection box 24. The handle 25 makes it easier for the operator to push and pull the fine material collection box 24, reducing manpower consumption.

[0025] In this embodiment, coarse material collection box 22 is located at the bottom of coarse material outlet 20, coarse material collection box 23 is located at the bottom of coarse material outlet 21, and fine material collection box 24 is located at the bottom of screen plate 19. By separating and collecting materials, calcium oxide particles of different sizes can be stored separately, which helps to ensure the particle size uniformity of each batch of products, thereby improving the consistency of product quality.

[0026] In this embodiment, a large sieve hole is provided on the first sieve plate 18, and a small sieve hole is provided on the second sieve plate 19. The outer side of the grinding rod 12 is in contact with the inner wall of the grinding table 8.

[0027] In this embodiment, during use, the raw material is poured into the grinding table 8, and the drive motor 4 is started to drive the rotating rod 5 to rotate, which in turn drives the worm gear 26 to rotate, which in turn drives the worm wheel 9 to rotate, causing the rotating shaft 10 to rotate, which in turn drives the connecting block 11 to rotate. This allows the grinding rod 12 to rotate against the inner wall of the grinding table 8, thereby grinding the raw material. The ground calcium oxide will fall onto the first sieve plate 18. The vibration motor 17 is started to drive the fixed plate 28, the first sieve plate 18, and the second sieve plate 19 to vibrate. By setting the spring 14, the lifting rod 15, the bottom column 13, and the top column 16, the vibration is made more uniform, thereby shaking and screening the calcium oxide on the first sieve plate 18. Calcium oxide that does not meet the requirements will enter the coarse material collection box 22 through the coarse material outlet, while qualified calcium oxide will fall onto the screen plate 19 through shaking. By setting the pore size of the screen plate 19 to be smaller than that of the screen plate 18, secondary filtration of calcium oxide can be achieved to achieve better results. Calcium oxide that does not meet the requirements will fall into the coarse material collection box 23 through the coarse material outlet, which facilitates the collection and secondary grinding of unqualified coarse material and reduces the defect rate. Calcium oxide that meets the requirements will enter the fine material collection box 24 through the screen plate 29. After collection, the fine material collection box 24 can be pulled out from the base plate 1 by pulling the handle 25 to collect the ground calcium oxide.
