Description

Technical Field

[0001] This utility model relates to the field of lithium slag powder production technology, and in particular to a grinding mill used in the production of lithium slag powder. Background Technology

[0002] Lithium slag powder is a byproduct of lithium carbonate production via the sulfuric acid process. After drying and grinding, it becomes a powder with amorphous silica and aluminum oxide as its main components, reaching a certain fineness. Lithium slag possesses positive and beneficial biochemical properties, improving the storage life of fruits and vegetables and potentially enhancing the disease resistance of certain crops. Preliminary field experiments have shown that applying a certain amount of lithium slag to the soil can prevent rice lodging and increase rice yield per acre. When it is necessary to grind lithium slag powder, a grinding mill is usually used. The current grinding mill has a fixed structure and a relatively simple function. During the grinding process, the lithium slag powder splashed and adheres to the inner wall of the grinding mill and cannot be cleaned in time. Furthermore, the lithium slag powder adhering to the inner wall of the grinding mill cannot be ground again, which affects the efficiency of use and causes waste. There is room for optimization.

[0003] Therefore, it is necessary to provide a grinding mill for the production of lithium slag powder to solve the above-mentioned technical problems. Utility Model Content

[0020] The following describes in detail a novel grinding mill for lithium slag powder production, with reference to specific embodiments.

[0021] refer to Figures 1 to 4 This utility model provides a grinding mill for lithium slag powder production, comprising: a grinding cylinder 1, wherein the grinding cylinder 1 is provided with a plurality of grinding rollers 12 driven by a driving device, the grinding cylinder 1 is provided with a grinding ring 16 inside, a plurality of cleaning brushes 17 are installed on the outer surface of the grinding ring 16, and an installation groove 18 is provided on the outer surface of the grinding ring 16 on one side of the cleaning brushes 17. The installation groove 18 is rotatably connected to a second grinding roller 19 through a rotating shaft. The top of the grinding ring 16 is connected to the outer surface of a moving cylinder 21 through a plurality of connecting rods 20. The top of the moving cylinder 21 is connected to the bottom of an electric telescopic rod 6. The top of the electric telescopic rod 6 is connected to the driving end of a rotary motor 15. The top of the rotary motor 15 is connected to the bottom of the lateral end of an L-shaped bracket 8.

[0022] It should be noted that: by setting up the electric telescopic rod 6, the grinding ring 16 can be moved up and down inside the grinding cylinder 1 by the extension and retraction of the electric telescopic rod 6. By setting up the rotary motor 15, the rotation of the rotary motor 15 drives the grinding ring 16 to rotate, thereby causing the cleaning brush 17 on the grinding ring 16 and the second grinding roller 19 to rotate accordingly, cleaning the lithium slag powder on the inner wall of the grinding cylinder 1. For the lithium slag powder that cannot be cleaned, it can be ground a second time by the second grinding roller 19, thereby improving the grinding efficiency.

[0023] In the embodiments of this utility model, reference is made to Figure 1 As shown, a rotating ring 9 is sleeved on the outer surface of the electric telescopic rod 6, and the rotating ring 9 is rotatably connected to the rotating groove 13, which is set on the inner surface of the grinding cylinder 1.

[0024] It should be noted that by setting the rotating groove 13, the stability of the rotating ring 9 during rotation can be improved by limiting the rotation of the rotating groove 13, thereby improving the stability of the electric telescopic rod 6 during rotation.

[0025] In the embodiments of this utility model, reference is made to Figure 1 As shown, the top of the grinding cylinder 1 is movably connected to the cylinder cover 2, and the top of the cylinder cover 2 is provided with a rotating hole 5 for rotating the electric telescopic rod 6.

[0026] It should be noted that by setting a cylinder cover 2 with a rotating hole 5, the electric telescopic rod 6 can be rotated without affecting the sealing of the grinding cylinder 1, thus enabling better cleaning of the inner wall of the grinding cylinder 1.

[0027] In the embodiments of this utility model, reference is made to Figure 1 , Figure 2 As shown, the top of the grinding cylinder 1 is provided with a connecting groove 4, and the bottom of the cylinder cover 2 is provided with a connecting ring 3 that cooperates with the connecting groove 4.

[0028] It should be noted that by setting the connecting groove 4 and the connecting ring 3, the sealing performance at the connection point can be improved when the cylinder cover 2 is connected to the grinding cylinder 1 through the connection of the connecting ring 3 and the connecting groove 4.

[0029] In the embodiments of this utility model, reference is made to Figure 1 As shown, the side of the cylinder cover 2 is provided with a slider 10, which is slidably connected to an electric slide rail 11, which is opposite to the bracket 8.

[0030] In the embodiments of this utility model, reference is made to Figure 1 As shown, the outer surface of the upper end of the electric telescopic rod 6 is provided with a retaining ring 14, and the outer diameter of the retaining ring 14 is larger than the inner diameter of the rotating hole 5.

[0031] It should be noted that by setting up the electric slide rail 11, the cylinder cover 2 can be moved up and down automatically. The retaining ring 14 can limit the movement of the cylinder cover 2, preventing it from moving up too much and causing damage to the rotary motor 15, which would affect subsequent use.

[0032] In the embodiments of this utility model, reference is made to Figure 1 As shown, the rotary motor 15 is installed inside the motor box 7, and the top of the motor box 7 is connected to the bottom of the horizontal end of the bracket 8.

[0033] It should be noted that by setting up the motor box 7, the rotary motor 15 can be protected to prevent damage to the motor caused by external forces during use, which would affect subsequent drive operations.

[0034] The working principle of the grinding mill for lithium slag powder production provided by this utility model is as follows: By setting up an electric telescopic rod 6, the grinding ring 16 can be moved up and down inside the grinding cylinder 1 through the extension and retraction of the electric telescopic rod 6. By setting up a rotary motor 15, the rotation of the rotary motor 15 drives the grinding ring 16 to rotate, thereby causing the cleaning brush 17 on the grinding ring 16 and the second grinding roller 19 to rotate accordingly, cleaning the lithium slag powder on the inner wall of the grinding cylinder 1. For lithium slag powder that cannot be cleaned, it can be ground a second time by the second grinding roller 19, thereby improving the grinding efficiency.

[0035] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0036] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
