Abstract
Description
Technical Field
[0001] This utility model relates to the field of dry grinding mill technology, and in particular to a dry grinding mill with a wear-resistant sealing structure. Background Technology
[0002] A dry grinding mill is an industrial device mainly used for grinding various materials. It uses high-speed rotating grinding parts to contact the material being ground, and uses friction and impact to grind or polish the material. It does not require the use of liquid as a grinding medium and is commonly used in metal processing, ceramic manufacturing and powder preparation. It can effectively improve the precision, surface quality and processing efficiency of materials. Because it does not produce a large amount of waste liquid during operation, it is relatively environmentally friendly and easy to handle in subsequent processes.
[0003] Dry grinding mills with wear-resistant sealing structures are upgrades from ordinary dry grinding mills. They are primarily used for dry grinding of various materials. Their wear-resistant structure is evident in the grinding parts and areas frequently in contact with materials, constructed from high-manganese steel, ceramics, and wear-resistant alloys. This allows them to withstand the intense impacts and friction during grinding, reducing wear and extending service life. The sealing structure is designed to prevent dust leakage, ensuring a clean working environment and avoiding material spillage. Common sealing methods include labyrinth seals, mechanical seals, and packing seals, which can be used individually or in combination. In industries such as cement, refractory materials, non-ferrous metal ore beneficiation, and glass ceramics, these dry grinding mills, with their wear-resistant and sealing properties, operate efficiently and stably, improving production efficiency and reducing maintenance costs. While protecting costs and meeting the environmental and production needs of enterprises, excessively high material moisture content can still affect grinding efficiency and sealing performance. Excessive moisture causes material to clump during grinding, impacting uniformity and efficiency. Existing technologies employ mechanical dehydration equipment, such as centrifuges and filter presses, to pre-dehydrate materials. Centrifugal force or pressure separates most of the moisture from the material, reducing its moisture content to a suitable range before it enters the dry grinding mill. This effectively improves grinding efficiency and equipment stability. However, direct collection can lead to some large, insufficiently ground particles being mixed into the collected product, resulting in uneven particle size and affecting subsequent processing and performance. Utility Model Content

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0031] Reference Figure 1 , Figure 2 and Figure 4 This utility model provides an embodiment of a dry grinding mill with a wear-resistant sealing structure, including a mounting platform 1. A body 3 is mounted on the top of the mounting platform 1. A discharge pipe 4 is connected to the rear side of the body 3. A collection box 5 is mounted on the bottom rear side of the mounting platform 1. A second motor 6 is mounted in the middle of the rear side of the collection box 5. A driving bevel gear 15 is fixedly connected to the output end of the second motor 6. Power is supplied to subsequent processes through the installation of the second motor 6. A connecting plate 18 is fixedly connected to the top rear side of the inner side of the mounting platform 1. A bidirectional threaded rod 17 is rotatably connected to the bottom of the connecting plate 18. A driven bevel gear 16 is fixedly connected to the middle of the bidirectional threaded rod 17. The bottom of the driven bevel gear 16 meshes with the top of the driving bevel gear 15. The upper and lower outer ends of the bidirectional threaded rod 17 are... A filter plate 14 is threadedly connected, and a limit rod 19 is slidably connected to the middle of the front side of the filter plate 14. A rotating cylinder 21 is fixedly connected to the bottom of the bidirectional threaded rod 17. A connecting rope 22 is fixedly connected to the left and right ends of the bottom of the rotating cylinder 21. A push plate 20 is fixedly connected to the front side of the connecting rope 22. The bottom of the push plate 20 is slidably connected to the inner bottom wall of the collection box 5. A heat dissipation mechanism 2 is installed on the top front side of the installation platform 1. The heat dissipation mechanism 2 is used for heat dissipation of the machine body 3. Support columns 11 are fixedly connected to the four corners of the bottom of the installation platform 1. A support plate 7 is fixedly connected to the lower middle part of the rear side of the collection box 5. A fixed circular plate 23 is fixedly connected to the upper and lower ends of the limit rod 19. A discharge chute 8 is opened at the bottom of the rear side of the collection box 5. The opening of the discharge chute 8 facilitates the collection of materials.
[0032] Specifically, after the material is ground by the machine body 3, it flows into the collection box 5 through the discharge pipe 4 connected to the rear of the machine body 3. At this time, the second motor 6 is started. The output end of the second motor 6 drives the active bevel gear 15 to rotate. The active bevel gear 15 meshes with the driven bevel gear 16, which in turn causes the bidirectional threaded rod 17 to rotate. This causes the two filter plates 14 to slide linearly along the bidirectional threaded rod 17 under the constraint of the limiting rod 19, thereby achieving the filtration of the material. At the same time, the rotating cylinder 21 rotates accordingly. Through the installation of the connecting rope 22, the push plate 20 is pulled, causing the push plate 20 to slide on the inner bottom wall of the collection box 5, and the material filtered by the filter plates 14 in the collection box 5 is collected in a concentrated manner.
[0033] Reference Figure 1 , Figure 3 and Figure 5 The heat dissipation mechanism 2 includes a slide rail 204, which is fixedly connected to the top front side of the mounting platform 1. A first motor 201 is installed at the top center of the mounting platform 1. A rotating short column 202 is fixedly connected to the output end of the first motor 201. A connecting rod 203 is fixedly connected to the front side of the rotating short column 202. A mounting block 206 is fixedly connected to the front side of the connecting rod 203. Sliding wheels 207 are fixedly connected to the bottom left and right ends of the mounting block 206. The bottom of the sliding wheels 207 is slidably connected to the top of the mounting platform 1. A fan 205 is installed in the middle of the mounting block 206. Support columns 11 are fixedly connected to the four corners of the bottom of the mounting platform 1. The installation of the support columns 11 ensures that the device can be installed stably.
[0034] Specifically, after the first motor 201 is started, its output end drives the rotating short column 202 to rotate, which in turn drives the connecting rod 203 to move. This causes the mounting block 206 to slide on the top of the mounting platform 1 via two sliding wheels 207. At the same time, restricted by the slide rail 204, the mounting block 206 moves along a predetermined trajectory, causing the fan 205 to move synchronously with the mounting block 206. During the movement, the fan 205 continues to run, generating airflow to dissipate heat from the machine body 3, ensuring the stable operation of the dry grinder and extending its service life.
[0035] Reference Figure 1 , Figure 2 and Figure 3 A sliding box 9 is fixedly connected to the middle right side of the collection box 5. Multiple hooks 10 are equidistantly slidably connected inside the sliding box 9. A slot plate 13 is fixedly connected to the right side of the installation platform 1. A notice board 12 is set inside the slot plate 13.
[0036] Specifically, the installation of hooks 10 facilitates the storage and use of parts, while the installation of notice boards 12 facilitates reminders to staff.
[0037] Working principle: After the material is ground by the machine body 3, it enters the collection box 5 through the discharge pipe 4 connected to the rear of the machine body 3. At this time, the second motor 6 is started. The output end of the second motor 6 drives the active bevel gear 15 to rotate. The active bevel gear 15 meshes with the driven bevel gear 16, thereby causing the bidirectional threaded rod 17 to rotate. This causes the two filter plates 14 to slide linearly along the bidirectional threaded rod 17 under the restriction of the limiting rod 19, thereby filtering the material. At the same time, the rotating cylinder 21 rotates with it. Through the installation of the connecting rope 22, it can pull the push plate 20, causing the push plate 20 to slide on the inner bottom wall of the collection box 5, thus collecting the material filtered by the filter plates 14 in the collection box 5.
[0038] When the first motor 201 is started, its output drives the rotating short column 202 to rotate, causing the connecting rod 203 to move accordingly. This causes the mounting block 206 to slide on the top of the mounting platform 1 via two sliding wheels 207. Simultaneously, it is limited by the slide rail 204, causing the mounting block 206 to move along a certain trajectory. Consequently, the fan 205 moves synchronously with the mounting block 206, continuously operating during the movement to generate airflow, thereby dissipating heat from the machine body 3, ensuring stable operation of the dry grinder, and extending its service life.
[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
