Description

Technical Field

[0001] The utility model belongs to the technical field of ceramic material processing, in particular to a grinding device for preparing wear-resistant ceramic materials. Background Art

[0002] With the continuous development and progress of society, the application of ceramic products is becoming more and more extensive. In the process of processing and preparing ceramics, it is often necessary to use a grinding device to grind the ceramic raw materials and grind large pieces of ceramic materials into smaller particles for subsequent further processing.

[0003] At present, most of the existing grinding devices use one or more pairs of grinding rollers to grind ceramic materials. The method is relatively simple, which affects the grinding effect of the ceramic materials. The ceramic materials can only be ground once, and then the ceramic materials after the initial grinding are ground a second time after the grinding. The grinding efficiency is low. At the same time, it is impossible to filter out large particles that are not ground sufficiently during the grinding process, which makes the grinding effect of the ceramic materials poor and affects the grinding quality of the ceramic materials.

[0004] In view of the above problems, we propose a grinding device for preparing wear-resistant ceramic materials. Utility Model Content

A support rod 18 is rotatably arranged at the bottom of the inner side of the grinding box 1, a fixed block 12 is fixed on the lower side of the inside of the grinding box 1, a second grinding block 15 is fixed on the upper end of the support rod 18, and a first grinding block 14 is fixed on the top of the second grinding block 15.

[0027] The grinding roller 2 is used to facilitate the preliminary crushing of the ceramic material to be ground. Combined with the filter plate 4, the ceramic material after preliminary crushing is filtered, so that the large particles of ceramic material that have not been crushed remain on the filter plate 4 and slide to the right along the inclined first guide plate 3. Under the action of the circulation mechanism, the large particles of ceramic material that have not been crushed are sent back to the position of the grinding roller 2 for further crushing, which is convenient for further grinding. The crushed small particles of ceramic material are filtered by the filter plate 4 and fall downward on the fixed block 12, and slide downward along the inner wall of the fixed block 12. Under the action of the support rod 18, the second grinding block 15 is driven to move synchronously with the first grinding block 14. Under the cooperation of the first grinding block 14 and the second grinding block 15 with the inner wall of the fixed block 12, the ceramic material is ground multiple times, which effectively improves the grinding effect of the ceramic material.

[0028] The circulation mechanism includes a return material cylinder 6, a rotating rod 7, a spiral blade 8, a material guide channel 10 and a return material pipe 11. A feed hopper 5 is arranged on the top of the grinding box 1, and the return material cylinder 6 is arranged on the right side of the grinding box 1. The rotating rod 7 rotates with the return material cylinder 6, and the spiral blade 8 is arranged on the rotating rod 7. The spiral blade 8 cooperates with the inner cavity of the return material cylinder 6. The material guide channel 10 is obliquely arranged between the grinding box 1 and the return material cylinder 6, and the two ends of the material guide channel 10 are respectively connected to the grinding box 1 and the inner cavity of the return material cylinder 6. The connecting part of the material guide channel 10 and the grinding box 1 cooperates with the right end of the first guide plate 3. The two ends of the return material pipe 11 are respectively connected to the feed hopper 5 and the return material cylinder 6, and the return material pipe 11 is inclined. The first transmission assembly 9 is arranged between the support rod 18 and the rotating rod 7.

[0029] Through the cooperation between the material guide channel 10 and the first material guide plate 3, it is convenient to guide the filtered large-particle ceramic material into the return barrel 6. Under the action of the first transmission component 9, it is convenient to drive the rotating rod 7 to rotate synchronously, and the rotating rod 7 drives the spiral blade 8 to rotate, thereby transporting the large-particle ceramic material entering the return barrel 6 upward, and sending it back to the feed hopper 5 through the return pipe 11 for further crushing, which effectively facilitates subsequent further grinding.

[0030] The linkage mechanism includes a linkage shaft 19, a first bevel gear 20, a second bevel gear 21, a driving gear 22, a driven gear 23 and a second transmission assembly 24. The linkage shaft 19 is arranged on the rear side of the bottom of the grinding box 1. The first bevel gear 20 and the second bevel gear 21 are respectively arranged on the linkage shaft 19 and the support rod 18, and the first bevel gear 20 is meshed with the second bevel gear 21. Both rotating shafts pass through the rear surface of the grinding box 1. The driving gear 22 and the driven gear 23 are respectively arranged on the left and right rotating shafts, and the driving gear 22 is meshed with the driven gear 23. The second transmission assembly 24 is arranged between the rear end of the linkage shaft 19 and the rotating shaft on the right.

[0031] A second guide plate 13 with an umbrella-shaped structure is fixed on the top of the first grinding block 14. The second guide plate 13 cooperates with the filter plate 4 and the upper opening of the fixed block 12 to guide the ceramic material after preliminary grinding between the first grinding block 14 and the fixed block 12 for further grinding. A third guide plate 25 with an annular structure is fixed obliquely on the lower side of the outer surface of the second grinding block 15 to make the ceramic material after grinding fall downward onto the fourth guide plate 16. The fourth guide plate 16 is fixed obliquely on the lower side of the inside of the grinding box 1. A discharge port is penetrated on the lower side of the left surface of the grinding box 1. The collecting box 17 is connected to the discharge port, and the left end of the fourth guide plate 16 cooperates with the collecting box 17, so as to guide the ceramic materials that have completed the grinding process to the inside of the collecting box 17 for unified processing. The support rod 18 rotates with the fourth guide plate 16, and a supporting frame 26 is fixed to the bottom of the grinding box 1. The support rod 18, the linkage shaft 19 and the rotating rod 7 all rotate with the supporting frame 26. The bottom of the collecting box 17 is fixedly connected to the supporting frame 26, and a movable door is movably provided on one side of the collecting box 17 to facilitate the removal of the ground ceramic materials collected in the collecting box 17.

[0032] A grinding motor 27 is installed on the rear side of the grinding box 1 through a bracket. The output shaft of the grinding motor 27 is connected to the rear end of the rotating shaft on the left side. The first transmission assembly 9 and the second transmission assembly 24 are both composed of pulleys and transmission belts. Two buffer baffles are elastically hinged on the inner wall of the feed hopper 5, which ensures that the ceramic material slowly enters the grinding box 1 and prevents the powder generated during the grinding process from floating outward.

[0033] Example:

[0034] When in use, firstly, the ceramic material to be ground is slowly put into the feed hopper 5, and falls between the two grinding rollers 2 through the feed hopper 5, and at the same time, the grinding motor 27 is started, and the left rotating shaft is driven by the grinding motor 27 to rotate, and under the meshing action of the driving gear 22 and the driven gear 23, the two grinding rollers 2 are driven to rotate synchronously, and the ceramic material falling between the two grinding rollers 2 is preliminarily ground;

[0035] The second transmission assembly 24 drives the linkage shaft 19 to rotate synchronously, and the meshing action of the first bevel gear 20 and the second bevel gear 21 drives the support rod 18 to rotate synchronously, and the second guide plate 13, the first grinding block 14 and the second grinding block 15 are driven to rotate synchronously through the support rod 18;

[0036] The ceramic material that has been preliminarily ground falls down onto the filter plate 4. Under the action of the filter plate 4, large particles of ceramic material are filtered out, and smaller particles of ceramic material pass through the filter plate 4 and fall down onto the second guide plate 13. During the process in which the second guide plate 13 rotates following the support rod 18, the smaller particles of ceramic material that have fallen onto the second guide plate 13 are thrown out under the action of centrifugation, fall onto the inclined surface inside the fixed block 12, and slide downward along the inclined surface inside the fixed block 12.

[0037] At the same time, under the action of the first grinding block 14, the ceramic material after the initial grinding is subjected to secondary grinding, and the ceramic material after the secondary grinding continues to slide down along the inner wall of the fixed block 12, and continues to be ground for the third time under the action of the second grinding block 15, which effectively improves the grinding effect of the ceramic material and solves the problem that the existing grinding device mostly uses one or more pairs of grinding rollers 2 to grind the ceramic material, the method is relatively single, which affects the grinding effect of the ceramic material, and can only grind the ceramic material once, and then grind the ceramic material after the initial grinding for the second time after the grinding, which has a low grinding efficiency;

[0038] The ground ceramic material falls downward onto the third guide plate 25. As the third guide plate 25 rotates with the second grinding block 15, the ground ceramic material is thrown out and falls onto the fourth guide plate 16 at the lower side. The fourth guide plate 16 slides to the left and enters the collection box 17 through the discharge port, so as to facilitate subsequent unified processing.

[0039] The filtered large-particle ceramic material slides to the right through the first guide plate 3, and slides into the return barrel 6 through the guide channel 10. At the same time, under the action of the first transmission component 9, the support rod 18 rotates, which drives the rotating rod 7 to rotate. Combined with the spiral blade 8, the large-particle ceramic material entering the return barrel 6 is transported upward. Under the inclination of the return pipe 11, the ceramic material in the return barrel 6 is transported back to the feed hopper 5, and then returns to between the two grinding rollers 2 for further grinding, which is convenient for subsequent further grinding. It solves the problem that the existing grinding device cannot filter out the large-particle material that is not sufficiently ground during the grinding process, resulting in poor grinding effect of the ceramic material and affecting the grinding quality of the ceramic material.

[0040] It should be further explained that the installation structure, connection method or setting method of each component in the utility model are all common mechanical methods, and they can be implemented as long as they can achieve their beneficial effects. At the same time, the grinding motor 27 in the utility model is purchased on the market, and technical personnel in this field can install and use it according to requirements.
