Description

Technical Field

[0001] The utility model relates to the technical field of silica gel production, and more specifically, it relates to a grinding device for silica gel production. Background Art

[0002] Silica gel has good stability and mechanical strength, so there are a large number of silica gel products on the market. There is a great demand for the production of silica gel products. When producing silica gel products, it is necessary to grind silica gel slurry through grinding equipment for subsequent molding processes such as compression molding and extrusion.

[0003] For common grinding devices for silica gel production, most of them carry out grinding processing through grinding rollers. However, it is difficult to grind all raw materials in place with only one grinding process. There may be particles with a volume larger than the production requirement, and workers need to screen the ground finished products, use screening equipment to screen out unqualified raw materials, and then put them into the grinding equipment for grinding again. This requires a large amount of labor from workers in production, and the production efficiency is not high. Moreover, general grinding devices do not have a separate feeding mechanism, and workers need to manually feed. Workers carry the raw materials above the grinding equipment and pour them in. Workers' manual feeding is carried out in multiple times, and the feeding is not uniform enough, suddenly increasing and decreasing the grinding demand, which is not conducive to the stable operation of the grinding equipment, may cause the grinding equipment to be blocked, and affect the grinding quality, etc. In addition, when the grinding roller grinds the raw materials, a large pressure will be generated between the raw materials and the grinding roller, and some raw materials may adhere to the surface of the grinding roller instead of falling normally. The raw materials adhering to the surface of the grinding roller will affect the contact between the corresponding position of the grinding roller and other raw materials, and affect the subsequent grinding quality.

The ground raw materials fall and come into contact with the screen filter 3. The screen filter 3 screens the ground raw materials. The raw materials with qualified sizes will pass through the screen filter 3 and fall, while the unqualified raw materials will be screened out. Under the guidance of the screen filter 3, they move upward to the feeding pipe 4. Through the operation of the feeding motor 5, the feeding screw conveyor roller 6 is driven to cooperate with the feeding pipe 4 to transport the raw materials upward, so that the raw materials are re-added to the machine shell 1 and ground by the grinding roller 2 again until the production requirements are met.

[0033] More specifically, when feeding, the materials are not directly added to the machine shell 1, but into the feeding hopper 10.

[0047] Specifically, the ground silica gel raw materials are discharged from the discharge pipe 27, and the opening and closing of the discharge pipe 27 are controlled by the switching valve 28.

[0048] In summary, when the overall equipment is in use or operation:

[0049] When using the equipment, connect the equipment to an external power supply device. When feeding materials, instead of directly adding the materials into the machine shell 1, add them into the feeding hopper 10. The feeding hopper 10 is used to load the materials and guide the materials into the feeding pipe 7. Start the stirring motor 20 to work. Supported by the support frame 19, drive the stirring shaft 21 to rotate through the stirring motor 20, and the stirring shaft 21 drives the stirring blades 22 to move, so that the stirring blades 22 stir the raw materials in the feeding hopper 10 to prevent the raw materials from being blocked. The silica gel raw materials fall into the feeding pipe 7. Through the work of the feeding motor 8, drive the feeding screw conveyor roller 9 to rotate. Through the cooperation of the feeding screw conveyor roller 9 and the feeding pipe 7, the raw materials accumulated under the feeding hopper 10 in the feeding pipe 7 are evenly sent out. The raw materials in the feeding hopper 10 will continue to fall into the feeding pipe 7 only after the lower space is emptied, so as to evenly add the silica gel raw materials into the machine shell 1 through the feeding pipe 7.

[0050] When grinding, the raw materials fall into the casing 1 under the action of the feeding pipe 7. The casing 1 provides a grinding space. After the raw materials enter the casing 1, they contact the grinding roller 2. The driving motor 23 provides power for the rotation of the grinding roller 2. When the grinding roller 2 rotates, it drives the transmission shaft 24 to rotate. Through the cooperation of the transmission wheel and the transmission belt 26, the rotation speeds of the two groups of grinding rollers 2 are kept consistent under the transmission of the transmission shaft 24, the transmission wheel and the transmission belt 26. The raw materials are ground by the grinding roller 2. After grinding, the raw materials fall and leave the grinding roller 2, contact the sieve filter 3. The sieve filter 3 screens the ground raw materials. The raw materials with qualified sizes will pass through the sieve filter 3 and fall, while the unqualified raw materials will be screened out. Guided by the sieve filter 3, they move upward to the feeding pipe 4. Through the operation of the feeding motor 5, the feeding screw blade conveying roller 6 cooperates with the feeding pipe 4 to transport the raw material box upward, so that the raw materials are re-added to the casing 1 and ground by the grinding roller 2 again until the production requirements are met. The ground silica gel raw materials are discharged from the discharge pipe 27, and the opening and closing of the discharge pipe 27 are controlled by the on-off valve 28.

[0051] When the grinding roller 2 is working, the cleaning scraper 11 contacts the lower end of the rotating grinding roller 2 and remains stable under the support of the mounting frame 13. The surface of the grinding roller 2 is treated, and the raw materials sticking to the grinding roller 2 are scraped off. Guided by the guiding plate 12, the raw materials fall stably and cooperate with the sieve filter 3. After the processing is completed, the opening and closing door 14 can be conveniently opened through the cooperation block 16 to expose the inside of the casing 1, which is convenient for disassembling the cleaning scraper 11 from the mounting frame 13 to clean the cleaning scraper 11 and recycle the raw materials remaining on the cleaning scraper 11. In addition to the cleaning scraper 11, the sieve filter 3 can also be taken out for cleaning. The sieve filter 3 maintains the overall structure through the mesh frame 17, and the mesh frame 17 is supported by the support frame 18 to keep stable. After the sieve filter 3 is taken out, it can be cleaned or it is convenient to replace the sieve filter 3 with different mesh diameters. After the cleaning is completed, the cleaning scraper 11 and the sieve filter 3 are reinstalled, then the opening and closing door 14 is closed, and the limiting strip 15 is rotated so that the limiting strip 15 cooperates with the cooperation block 16. Under the action of gravity and the restriction of the cooperation block 16 on the limiting strip 15, the movable end of the limiting strip 15 blocks the opening and closing door 14 to limit the opening and closing of the opening and closing door 14.
