Description

Technical Field

[0001] This utility model relates to the field of brown fused alumina processing, and in particular to an abrasive device for processing brown fused alumina sand. Background Technology

[0002] Brown fused alumina, also known as corundum, is a brownish-red synthetic corundum produced by melting and reducing bauxite, carbon materials, and iron filings in an electric arc furnace, hence its name. Its main chemical component is Al₂O₃, with a content of 95.00%-97.00%, and it also contains small amounts of Fe, Si, Ti, etc. Brown fused alumina is a basic abrasive, widely used due to its good grinding performance, wide applicability, and low price.

A crushing mechanism is arranged on the upper inner side of the main body structure, and a filtering mechanism is arranged in the middle inner side of the main body structure. A driving device is arranged at the left end of the crushing mechanism. This invention uses a motor to drive a first transmission wheel to rotate, which in turn drives a second transmission wheel to rotate, thereby driving a bearing to rotate. The bearing then drives a crushing cylinder to rotate, thus crushing the material through the crushing cylinder. Furthermore, the texture on the crushing cylinder can improve the fineness of the crushing, thereby effectively improving the working efficiency of the device. The connector and the mating plate are fixed by fixing bolts, allowing the operator to disassemble the connector and the mating plate with tools, facilitating the cleaning or replacement of the filter screen, thereby improving the ease of use of the device.

[0004] However, the above-mentioned patent still has some shortcomings when used. When cleaning the raw materials, the above-mentioned device requires the staff to take out the collection box and collect the raw materials. Manual disassembly and collection is time-consuming and labor-intensive. Especially for large equipment, the downtime is too long, which reduces the production capacity and thus reduces the processing efficiency. To this end, we propose an abrasive device for processing brown corundum sand to solve the above problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 In this utility model, an abrasive device for processing brown fused alumina sand includes an abrasive box 1, a cleaning component 6 connected to the outer surface of the abrasive box 1, a hopper 7 connected to the upper surface of the abrasive box 1, two first guide plates 8 connected to the inner wall of the abrasive box 1, a filter screen 9 connected to the inner wall of the abrasive box 1, two second guide plates 10 connected to the inner wall of the abrasive box 1, a first motor 11 connected to the outer surface of the abrasive box 1, a first rotating column 12 connected to the output end of the first motor 11, a first bearing 13 embedded in the inner wall of the abrasive box 1, the inner ring of the first bearing 13 connected to the outer surface of the first rotating column 12, and a spiral blade 14 connected to the outer surface of the first rotating column 12.

[0024] A support assembly 2 is connected to the bottom surface of the abrasive box 1. The support assembly 2 includes multiple support columns 201, and each support column 201 is connected to a base 202 at its bottom end. Through the cooperation of the support columns 201 and the base 202, the device can be effectively supported, preventing the device from shaking during use and increasing the stability of the device. A protective assembly 3 is hinged to the upper surface of the hopper 7. The protective assembly 3 includes a cover plate 301, and a pull rod 302 is connected to the upper surface of the cover plate 301. Through the cooperation of the cover plate 301 and the pull rod 302, the cover plate 301 can effectively prevent raw materials from splashing out of the hopper 7 during the operation of the equipment, avoiding injury to the operator, ensuring the safety of the operation process, and providing a safety guarantee for the stable operation of the equipment.

[0025] The outer surface of the abrasive box 1 is connected to a first crushing component 4. The first crushing component 4 includes a second motor 401 and two sets of second bearings 402. Both sets of second bearings 402 are located on the inner wall of the abrasive box 1. The inner ring of each set of second bearings 402 is connected to a second rotating column 403. One end of one of the second rotating columns 403 is connected to the output end of the second motor 401. The outer surfaces of the two second rotating columns 403 are connected to first crushing rollers 404. The outer surfaces of the two second rotating columns 403 are connected to gears 405. The two gears 405 mesh with each other. The second motor 401 drives one of the second rotating columns 403 to rotate. Because the two gears 405 mesh, the unrotated second rotating column 403 rotates using the rotating second rotating column 403, thereby causing the two first crushing rollers 404 to rotate synchronously to crush the raw materials for the first time. Different raw materials can be crushed into the same size, which is beneficial to the convenience of subsequent processing.

[0026] The outer surface of the abrasive box 1 is connected to a second crushing component 5. The second crushing component 5 includes two third motors 501 and two sets of third bearings 503. Both sets of third bearings 503 are located on the inner wall of the abrasive box 1. The output ends of the two third motors 501 are connected to third rotating columns 502. The inner rings of the two sets of third bearings 503 are connected to the outer surface of the third rotating columns 502. The outer surfaces of the two third rotating columns 502 are connected to second crushing rollers 504. The third motors 501 drive the third rotating columns 502 to rotate using the third bearings 503, thereby causing the second crushing rollers 504 to rotate on the outer surface of the third rotating columns 502. This allows the raw material to be further crushed by the second crushing component 5 after being initially crushed by the first crushing component 4. By using crushing rollers of different specifications and a reasonable power drive structure, the brown fused alumina raw material can be crushed more finely, meeting the requirements of different processing scenarios for the particle size of brown fused alumina sand and improving product quality.

[0027] The cleaning component 6 includes a fourth motor 601, two fourth bearings 603, and a slide rod 605. The two fourth bearings 603 are located on the inner wall of the abrasive box 1, and the slide rod 605 is located inside the abrasive box 1. The output end of the fourth motor 601 is connected to a threaded rod 602. The inner rings of the two fourth bearings 603 are connected to the outer surface of the threaded rod 602. A nut 604 is threaded onto the outer surface of the threaded rod 602. A slider 606 is slidably connected to the outer surface of the slide rod 605. An adjusting plate 607 is connected to the bottom surface of the nut 604 and the bottom surface of the slider 606. A brush 608 is connected to the bottom surface of the filter screen 9. The bottom surface of the brush 608 contacts the upper surface of the filter screen 9. The fourth motor 601 drives the threaded rod 602 to rotate, causing the nut 604 to move on the threaded rod 602. This causes the nut 604 to drive the connected adjusting plate 607 and brush 608 to move in cooperation with the slide rod 605 and the slider 606, thereby realizing automatic cleaning of the filter screen 9, reducing manual intervention, reducing labor intensity, and also cleaning the filter screen 9 in a timely manner during equipment operation, ensuring the stability of the filtration effect and further improving processing efficiency.

[0028] The working principle of this utility model is as follows:

[0029] In use, brown fused alumina raw material is fed into the abrasive box 1 through the hopper 7. After feeding, the protective component 3 is closed to prevent the raw material from splashing during processing. Then, the second motor 401 is started, causing one of the second rotating columns 403 to rotate. The gear 405 on the second rotating column 403 meshes with the gear 405 on the other second rotating column 403, causing the two second rotating columns 403 to rotate synchronously. This drives the first crushing roller 404 to initially crush the fed raw material. The initially crushed raw material slides down the first guide plate 8 to the second crushing component 5 under the action of gravity. Then, the two third motors 501 are started, causing the third rotating column 502 to rotate, which in turn drives the second crushing roller 504 to further crush the initially crushed raw material. The raw material is crushed to make it finer. The crushed material falls onto the filter screen 9. Brown corundum sand that meets the particle size requirements passes through the filter screen 9 and slides down under the guidance of the second guide plate 10. Then, the first motor 11 is started, which makes the first rotating column 12 rotate under the action of the first bearing 13. This causes the spiral blade 14 to rotate on the outer surface of the first rotating column 12, conveying the filtered brown corundum sand to the designated collection position for automatic collection. Finally, the fourth motor 601 is started, which makes the threaded rod 602 rotate under the action of the fourth bearing 603. This causes the nut 604 to drive the adjusting plate 607 and the brush 608 to move under the cooperation of the slider 606 and the slide rod 605, thereby cleaning the filter screen 9.

[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
