Abstract
Description
Technical Field
[0001] The present application relates to the technical field of ball mills, and in particular to a partition plate structure of a mill. Background Art
[0002] The partition plates of a mill generally have the functions of separating grinding bodies of different specifications, controlling material flow rate, regulating ventilation volume in the mill and preventing large particles of material from rushing to the discharge end. In the existing mill, during the grinding process, the surface of the partition plates is easily collided, resulting in damage and deformation of the blocking parts on the surface of the partition plates, making it impossible to ensure the screening efficiency. The maintenance and replacement process of the partition plates is complicated, and most of the wind inside the ball mill passes directly through the central ventilation plate, resulting in uneven wind reception of the materials on both sides of the partition plates. If the damaged parts are not replaced in time, the materials are likely to accumulate on the partition plates, resulting in blockage of the grate holes of the partition plates, and the inability of the materials in the coarse grinding bin to enter the fine grinding bin smoothly, resulting in reduced grinding efficiency, affecting the hourly output of the mill and increasing the power consumption of the grinding system. Summary of the invention

The plurality of outer splicing blocks, the plurality of middle splicing blocks and the plurality of inner splicing blocks are all fixedly mounted on the mounting ring via a plurality of locking pieces.
[0006] Furthermore, a first plug-in block is provided on the outer splicing block, and the first plug-in block is plug-matched with the middle splicing block, a second plug-in block is provided on the middle splicing block, and the second plug-in block is plug-matched with the inner splicing block, and a third plug-in block is provided on the inner splicing block, and the third plug-in block is plug-matched with the mounting ring.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0027] The embodiment of the present application discloses a partition plate structure of a grinding mill.
[0028] Reference Figure 1-4 A partition plate structure of a mill comprises a mounting ring 1, on both side walls of the mounting ring 1 are detachably provided with a splicing assembly 2, a mounting groove 11 is provided on the circumference of the mounting ring 1, a screening net 12 is provided in the groove, a through hole 13 is provided in the middle of the mounting ring 1, and a retaining net 14 is fixedly provided between the through holes 13;
[0029] The assembly assembly includes a plurality of outer splicing blocks 21, a plurality of middle splicing blocks 22, a plurality of inner splicing blocks 23 and a plurality of locking members 24. The plurality of outer splicing blocks 21, the plurality of middle splicing blocks 22 and the plurality of inner splicing blocks 23 are all fixedly mounted on the mounting ring 1 through the plurality of locking members 24.
[0030] When the locking member 24 is a screw and a nut, the screw passes through the mounting ring 1 and the assembly component, and then the nuts are tightened at both ends of the screw to relatively fix the assembly component and the mounting ring 1.
[0031] When the locking member 24 is a bolt, the bolt passes through the assembly component, and then the bolt is threadedly connected with the mounting ring 1, so that the assembly component and the mounting ring 1 are relatively fixed;
[0032] When in use, by fixing the assembling component on the outer wall of the mounting ring 1, the damage to the screening mesh 12 caused by the grinding parts in the mill can be effectively reduced, and the service life of the screening mesh 12 can be extended. The assembling component includes multiple outer splicing blocks 21, multiple middle splicing blocks 22, multiple inner splicing blocks 23 and multiple locking parts 24, which can divide the assembling component into multiple parts to protect the screening mesh 12. When damage occurs, it can be replaced locally and quickly to prevent the screening mesh 12 from being blocked, thereby ensuring the production efficiency of the mill.
[0033] Reference Figure 4 The outer splicing block 21 is provided with a first plug-in block 211, and the first plug-in block 211 is plugged and matched with the middle splicing block 22, the middle splicing block 22 is provided with a second plug-in block 221, and the second plug-in block 221 is plugged and matched with the inner splicing block 23, and the inner splicing block 23 is provided with a third plug-in block 231, and the third plug-in block 231 is plugged and matched with the mounting ring 1;
[0034] When in use, first install the third plug-in block 231 of the inner splicing block 23 with the mounting ring 1, then splice the second plug-in block 221 of the middle splicing block 22 with the inner splicing block 23, and finally splice the first plug-in block 211 of the outer splicing block 21 with the middle splicing block 22, which can effectively and quickly perform positioning and assembly.
[0035] More specifically, the outer assembling block 21, the middle assembling block 22, and the inner assembling block 23 are sequentially connected to form a fan-shaped arrangement, and the fan-shaped arrangement can better enable adjacent assembling components to fit better.
[0036] Reference Figure 1, Figure 4 The inner walls of the outer splicing block 21, the middle splicing block 22, and the inner splicing block 23 are all inclined. When in use, the inclined setting can effectively prevent materials from accumulating on the inner walls of the outer splicing block 21, the middle splicing block 22, and the inner splicing block 23 and causing agglomeration, thereby ensuring the screening efficiency of the screening net 12.
[0037] Reference Figure 1-3 A material retaining ring 15 is arranged in the middle of the mounting ring 1. The setting of the material retaining ring 15 can effectively prevent larger materials from entering the through hole 13 of the mounting ring 1 during the falling process, thereby reducing the collision and wear of the larger materials on the retaining net 14.
[0038] More specifically, the mounting ring 1, the outer joint block 21, the middle joint block 22, and the inner joint block 23 are all made of AR400 steel plate material. AR400 is a wear-resistant steel with high hardness and wear resistance. It is suitable for cement partition plates and can better resist the wear of cement particles.
[0039] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
