Description

Technical Field

[0001] This utility model relates to the field of grinding technology, and in particular to a grinding device for processing silica sand. Background Technology

[0002] Silica sand, as an important non-metallic mineral resource, has wide applications in construction, glass, ceramics, metallurgy, and chemical industries. With the continuous development of these fields, the requirements for silica sand fineness are becoming increasingly stringent. For example, in the construction industry, fine silica sand powder can be used to prepare high-performance concrete and mortar; in the glass industry, high-purity fine silica sand powder is a major raw material for manufacturing high-quality glass. Therefore, the market demand for grinding equipment for silica sand processing is constantly increasing.

[0003] The quality of the silica sand raw material meets the production requirements. Check whether all parts of the grinding device are intact. According to the production requirements, set the grinding fineness, output and other parameters of the grinding device. Start the vibrating feeder or elevator to feed the silica sand raw material into the grinding chamber. According to the production capacity of the grinding device and the characteristics of the raw material, adjust the feed rate of the feeder to ensure the uniform distribution of silica sand in the grinding chamber. Start the grinding components such as grinding rollers and grinding discs to start grinding the silica sand. Observe the grinding of silica sand in the grinding chamber through the monitoring equipment. Start the bag dust collector or cyclone dust collector to collect the dust generated during grinding and grading. Start the conveyor belt or discharge port to discharge the qualified silica sand fine powder. After completing the production task, stop the operation of each part of the grinding device according to the operation sequence.

[0004] Existing silica sand grinding equipment often results in uneven particle size distribution after grinding when the grinding time is insufficient. There are both excessively coarse and excessively fine particles. Furthermore, these devices lack automatic recycling and secondary grinding functions, which means that particles that have not reached the ideal grinding fineness cannot be automatically sent back to the grinding area for further processing. This defect forces operators to re-feed the material, which not only increases operating costs but also prolongs the overall processing time and reduces production efficiency. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a grinding device for silica sand processing, comprising...

[0006] The machine body has a processing cavity inside;

The outer wall of the second driven wheel is fixedly connected to a plurality of evenly distributed second push rods that are fixedly connected to the top of the moving plate.

[0013] Preferably, a plurality of linearly distributed springs are connected between the bottom end of the moving plate and the bottom end of the inner wall of the machine body, and a second motor is fixedly installed at the top end of the conveying pipe.

This realizes the automatic screening and recycling of materials and improves the overall efficiency.

[0017] 2. After the first motor is started, it drives the first push rod and the second push rod to move synchronously, contact the moving plate and compress the spring.

This not only enhances the screening effect and improves the efficiency of particle separation, but also significantly improves the operating speed of the entire process and the overall production efficiency.

Detailed Implementation

[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0027] Example 1

[0028] Reference Figure 1-6 This is the first embodiment of the present invention, which provides a grinding device for processing silica sand, including a body 1. The body 1 has a processing chamber inside. Two grinding wheels 9 are rotatably connected to the inner wall of the processing chamber in a mirror arrangement. A liftable filter plate 10 is slidably connected to the inner wall of the processing chamber. The outer wall of the filter plate 10 has multiple fine through holes. Both ends of the outer wall of the filter plate 10 are fixedly connected to a movable plate 11 that is slidably connected to the inner wall of the body 1. The inner wall of the processing chamber has a discharge pipe 26 for collecting larger particles. The outer wall of the discharge pipe 26 is fixedly connected to and communicates with a conveying pipe 5. The inner wall of the conveying pipe 5 is slidably connected to a spiral pusher plate 25 for pushing larger particles to a feed pipe 16. The inner wall of the conveying pipe 5 has a feed pipe 16 that communicates with the processing chamber.

[0029] A first motor 6 is fixedly installed on the outer wall of the machine body 1. The first motor 6 is used to drive the grinding wheel 9 to rotate and drive the filter plate 10 to move back and forth. The output end of the first motor 6 is fixedly connected to a main shaft that is fixedly connected to the inner wall of the grinding wheel 9. A drive gear 14 is fixedly connected to the outer wall of the main shaft. A driven gear 15 that is fixedly connected to the outer wall of another grinding wheel 9 meshes with the outer wall of the drive gear 14.

[0030] A first drive wheel 18 is fixedly connected to the outer wall of the main shaft. A first transmission belt 19 is slidably connected to the outer wall of the first drive wheel 18. A first driven wheel 20 is slidably connected to the inner wall of the machine body 1. The first driven wheel 20 is used to drive the first push rod 17 to rotate. A plurality of first push rods 17 arranged in a circular array and slidably connected to the top of the moving plate 11 are fixedly connected to the outer wall of the first driven wheel 20. The first push rods 17 are used to push the moving plate 11.

[0031] The outer wall of the grinding wheel 9 is fixedly connected to a second driving wheel 21 that is slidably connected to the inner wall of the machine body 1. The outer wall of the second driving wheel 21 is slidably connected to a second transmission belt 22. The inner wall of the second transmission belt 22 is slidably connected to a second driven wheel 23. The outer wall of the second driven wheel 23 is fixedly connected to a plurality of evenly distributed second push rods 24 that are fixedly connected to the top of the moving plate 11. The second push rods 24 rotate synchronously with the first push rod 17 to push the moving plate 11.

[0032] During use, the first motor 6 is started, which drives the drive gear 14 to rotate through the main shaft. The drive gear 14 drives the grinding wheel 9 to rotate through the driven gear 15. At the same time, the main shaft drives the first drive wheel 18 to rotate. The first drive wheel 18 drives the first driven wheel 20 to rotate through the first transmission belt 19. The first driven wheel 20 drives the first push rod 17 to rotate and press the moving plate 11. At the same time, the grinding wheel 9 drives the second transmission belt 22 to rotate through the second drive wheel 21. The second transmission belt 22 drives the second push rod 24 to rotate through the second driven wheel 23.

[0033] The first push rod 17 and the second push rod 24 simultaneously push the moving plate 11, which compresses the spring 13. When the first push rod 17 and the second push rod 24 disengage from the moving plate 11, the spring 13 is released and drives the filter plate 10 to reset through the moving plate 11. The filter plate 10 moves back and forth, and the top cover 7 is opened to pour in silica sand. After being ground by the grinding wheel 9 and the grinding ball 12, the sand falls into the filter plate 10. The filter plate 10 filters out the finer particles and enters the drawer 3.

[0034] Example 2

[0035] Reference Figure 1 , Figure 2 , Figure 3 and Figure 6 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: a plurality of linearly distributed springs 13 are connected between the bottom end of the moving plate 11 and the bottom end of the inner wall of the machine body 1; a second motor 8 is fixedly installed at the top end of the conveying pipe 5; and the output end of the second motor 8 is fixedly connected to a rotating shaft that is fixedly connected to the inner wall of the spiral push plate 25.

[0036] A drawer 3 is slidably connected to the inner wall of the processing chamber, and a handle 4 is fixedly connected to the outer wall of the drawer 3. An observation window 2 is opened on the outer wall of the machine body 1. A top cover 7 is slidably connected to the top of the machine body 1. Multiple evenly distributed grinding balls 12 are fixedly connected to the outer wall of the grinding wheel 9.

[0037] During use, since the filter plate 10 is inclined, the filter plate 10 screens out coarser particles that flow to the discharge pipe 26. The particles enter the spiral push plate 25 through the discharge pipe 26. The second motor 8 is started and drives the spiral push plate 25 to rotate through the rotating shaft, and the particles are pushed stably until they pass through the feed pipe 16. The coarser particles enter the processing chamber through the feed pipe 16 and are ground again by the grinding wheel 9. The operation is then completed.

[0038] The remaining structure is the same as that in Example 1.

[0039] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
