Description

Technical Field

[0001] The utility model relates to the technical field of ball mill maintenance, in particular to a ball mill facilitating the replacement of liners. Background Art

[0002] A ball mill is a device used to crush, mix or stir materials. It usually consists of a rotating container (usually cylindrical) and some spherical abrasives. These abrasives will roll, rotate or vibrate inside the container, thereby grinding or mixing the materials. Ball mills are widely used in various industrial fields, such as mining, metallurgy, chemical industry, building materials, etc., to prepare powdered materials or mix materials with different components.

[0003] Currently, an existing device (such as patent number: CN220405850U) discloses a ball mill liner assembly facilitating replacement. In this device, the fixed frame and the rotating cylinder combination mechanism are fixedly connected. Since the two are fixedly connected, the fixed frame and the cylinder body are integrated. The first liner and the second liner are embedded into the fixed frame, and then the hole positions of the first liner and the second liner communicate with the fixed holes on the cylinder body, achieving the effects of rapid installation and rapid fixation, and facilitating subsequent maintenance.

[0004] However, during the implementation of the above technical solution, it is found that there are at least the following technical problems: When installing the above device, the gap between the liner and the cylinder body needs to be padded with sealing packing. This will cause the gap between the liner and the cylinder body to become smaller, but it will also cause the friction force between the liner and the cylinder body to increase due to the replenishment of the packing, making it difficult for the staff to remove the liner, which is not convenient enough and lacks practicality and needs to be improved. Summary of the Utility Model

[0005] (I) Technical Problems to be Solved

[0006] In view of the deficiencies of the prior art, the utility model provides a ball mill facilitating the replacement of liners, solving the technical problem of insufficient practicality of the existing device.

[0007] (II) Technical Solutions

[0008] To achieve the above objectives, the utility model is realized through the following technical solutions:

[0009] A ball mill facilitating the replacement of liners includes a ball mill cylinder body;

[0010] An ejection mechanism is fixedly installed inside the ball mill cylinder body;

[0011] The ejection mechanism includes an inner ring, on the side wall of which an amplification ring is fixedly installed. The amplification ring is fixedly installed with the ball mill cylinder body. A plurality of chutes are opened inside the amplification ring, and a first circular groove is penetrated inside the inner ring. Each first circular groove communicates with the chute, and a lead screw is rotatably installed inside each chute.

[0012] Preferably, each lead screw is partially exposed outside the amplification ring. A slider is slidably installed inside each chute. Each slider is threadedly installed with the lead screw. A ejector rod is symmetrically and fixedly installed on the side wall of each slider. Each ejector rod is located inside the first circular groove, and each ejector rod is slidably installed with the first circular groove.

[0013] Preferably, each ejector rod is located inside the ball mill cylinder body. A plurality of clamping plates are fixedly installed on the inner wall of the ball mill cylinder body. Each ejection mechanism is located between the clamping plates. A clamping groove is symmetrically penetrated through the inner wall of each clamping plate, and a clamping block is slidably installed inside each clamping groove.

[0014] Preferably, a lining plate body is fixedly installed between every two of the clamping blocks. A second circular groove is opened inside each lining plate body. Each second circular groove is adapted to the ejector rod. Screws are symmetrically threadedly installed between each lining plate body and the ball mill cylinder body.

[0015] (III) Beneficial effects

[0016] First, when it is necessary to take out the clamping block, by rotating the lead screw, a threaded drive occurs between the lead screw and the slider, and then a threaded drive occurs with the slider, so that the slider drives the ejector rod to move away from the side of the amplification ring, and then ejects the lining plate body from the end of the second circular groove, avoiding the problem that it is inconvenient to take out the clamping block due to the large friction between the filler and the clamping block, improving the disassembly portability and increasing the practicability.

[0017] Second, by optimizing the structure and layout of the device, the ejection mechanism in the device can be conveniently installed on the inner wall of the ball mill cylinder body by using a welding process additionally later, which is convenient for additional installation and has strong expandability, and further improves the practicability.

[0026] Embodiment

[0027] As Figures 1 - 5 shown, the technical solution in the embodiment of the present application effectively solves the technical problem of insufficient practicability of the existing device, and the general idea is as follows:

[0028] In view of the problems existing in the prior art, the present utility model provides a ball mill facilitating the replacement of the lining plate, including a cylinder body 11 of the ball mill;

[0029] An ejection mechanism is fixedly installed inside the cylinder body 11 of the ball mill;

[0030] The ejection mechanism includes an inner ring 12. An amplification ring 13 is fixedly installed on the side wall of the inner ring 12. The amplification ring 13 is fixedly installed with the ball mill cylinder 11. A plurality of chutes 14 are opened inside the amplification ring 13. A first circular groove 15 is penetrated and opened inside the inner ring 12. Each first circular groove 15 communicates with the chute 14. A lead screw 16 is rotatably installed inside each chute 14. Each lead screw 16 is partially exposed outside the amplification ring 13. A slider 17 is slidably installed inside each chute 14. Each slider 17 is threadedly installed with the lead screw 16. A ejector rod 18 is symmetrically and fixedly installed on the side wall of each slider 17. Each ejector rod 18 is located inside the first circular groove 15. Each ejector rod 18 is slidably installed with the first circular groove 15. Each ejector rod 18 is located inside the ball mill cylinder 11. A plurality of clamping plates 19 are fixedly installed on the inner wall of the ball mill cylinder 11. When it is necessary to take out the block 22, by rotating the lead screw 16, the lead screw 16 and the slider 17 perform a threaded drive, and then a threaded drive occurs with the slider 17, so that the slider 17 drives the ejector rod 18 to move away from the side of the amplification ring 13, and then the lining body 23 is ejected from the end of the second circular groove 24, avoiding the problem that the block 22 is inconvenient to take out due to the large friction between the filler and the block 22, improving the disassembly portability and increasing the practicality.

[0031] Each ejection mechanism is located between the clamping plates 19. A clamping groove 21 is symmetrically penetrated and opened on the inner wall of each clamping plate 19. A block 22 is slidably installed inside each clamping groove 21. A lining body 23 is fixedly installed between every two blocks 22. A second circular groove 24 is opened inside each lining body 23. Each second circular groove 24 is adapted to the ejector rod 18. A screw 25 is symmetrically and threadedly installed between each lining body 23 and the ball mill cylinder 11. When it is necessary to install the lining body 23, the staff can apply filler on the ball mill cylinder 11 between each group of clamping plates 19. Then the staff can pick up the lining body 23, align the block 22 with the clamping groove 21 of the clamping plate 19 and align the second circular groove 24 with the inside of the ejector rod 18 and slide it in. Then the staff can push the lining body 23 towards the inner ring 12 side, so that the lining body 23 drives the block 22 to slide into the end of the clamping groove 21 and fit with the inner ring 12. At this time, the placement is completed.

[0032] Working principle:

[0033] First step, when it is necessary to install the liner body 23, the staff can apply filler on the ball mill cylinder body 11 between each group of clamping plates 19. Then the staff can pick up the liner body 23, align the clamping block 22 with the clamping groove 21 of the clamping plate 19 and align the second circular groove 24 with the inside of the ejector rod 18 and slide it in. Then the staff can push the liner body 23 towards the inner ring 12 side, so that the liner body 23 drives the clamping block 22 to slide into the end of the clamping groove 21 and fit with the inner ring 12. At this time, the placement is completed. Then the staff can use the screw 25 to connect the liner body 23 with the ball mill cylinder body 11. Then the staff can repeat the above steps to assemble the remaining liner bodies 23;

[0034] Second step, when it is necessary to take out the clamping block 22, the staff can remove the connected screw 25 according to the position of the clamping block 22 to be taken out, and determine the screw rod 16 that needs to be rotated next according to the ejector rod 18 clamped by the clamping block 22 to be taken out. When the screw rod 16 rotates, the screw rod 16 will have a threaded drive with the slider 17, and then have a threaded drive with the slider 17, so that the slider 17 drives the ejector rod 18 to move away from the side driven by the amplification ring 13, and then eject the liner body 23 from the end of the second circular groove 24, avoiding the problem that the clamping block 22 is not convenient to take out due to the large friction between the filler and the clamping block 22.

[0035] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made on the basis of the above description.
