Description

Technical Field

[0001] This utility model relates to the field of ball mill technology, specifically to a ball mill for aluminum ash slag recycling. Background Technology

[0002] A ball mill is a mineral crushing device, generally consisting of a rotatable cylinder with a feed inlet and a discharge outlet at each end. Driven by a motor, the cylinder contains multiple steel balls. As the cylinder rotates, centrifugal force and friction cause the steel balls to be lifted to a high position, then drop due to reduced friction, impacting the minerals on the bottom wall of the cylinder's inner cavity, continuously crushing the minerals until they reach the desired particle size. In the aluminum ash slag recycling process, the ball mill plays a crucial role, bearing the responsibility of grinding the aluminum ash slag to a suitable particle size, laying a solid foundation for the subsequent separation and extraction of valuable metals.

[0003] Existing ball mills for aluminum ash slag recycling directly feed materials into the equipment, which is not conducive to crushing large pieces of aluminum ash slag into smaller particles for more efficient subsequent separation and purification processes. Furthermore, materials easily become entangled on the crushing shaft during crushing, causing equipment blockage and affecting the continuity and stability of production. Additionally, the lack of an effective support mechanism on the inner wall of the ball mill prevents the grinding steel balls from being effectively lifted and thrown, resulting in insufficient impact and grinding between the grinding steel balls and the aluminum ash slag, leading to low grinding efficiency. Therefore, this utility model provides a ball mill for aluminum ash slag recycling. Utility Model Content

It solves the problems of existing ball mills for aluminum ash slag recycling, where materials are directly fed into the equipment, making it difficult to crush large pieces of aluminum ash slag into smaller particles for more efficient subsequent separation and purification processes. Furthermore, the material easily becomes entangled on the crushing shaft during crushing, causing equipment blockage and affecting the continuity and stability of production. Additionally, the lack of an effective support mechanism on the inner wall of the ball mill prevents the grinding steel balls from being effectively lifted and thrown, resulting in insufficient impact and grinding between the grinding steel balls and the aluminum ash slag, leading to low grinding efficiency.

[0013] Beneficial effects

[0014] This utility model provides a ball mill for aluminum ash slag recycling. Compared with the prior art, it has the following advantages:

[0015] Beneficial effects:

[0016] Firstly, in this invention, aluminum ash slag enters the crushing shell from the feeding shell. The rotation of the crushing shaft drives the crushing teeth to perform preliminary crushing of the aluminum ash slag. The cleaning rod removes material residue between the crushing teeth through a gear-like structure to prevent blockage. Through the combined design of the crushing shaft and the cleaning rod, not only is pre-crushing achieved, but the crushing teeth can also be automatically cleaned to crush the aluminum ash slag, breaking large pieces of aluminum ash slag into smaller particles, reducing the burden on the subsequent ball mill grinding and improving the efficiency of the entire recycling process.

[0017] Secondly, this utility model uses a support plate to support and lift the internal grinding steel balls to the top of the ball mill. When the mill rotates, the grinding steel balls can fall from the top and work with the evenly distributed grinding rods inside for grinding. When the main body of the ball mill rotates, it works together with the fixed grinding rods to impact and grind the aluminum ash slag, achieving efficient crushing and ensuring that the aluminum ash slag is fully ground, thus improving the recycling effect.

[0023] 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.

[0024] Please see Figures 1-4 This utility model provides a technical solution: a ball mill for aluminum ash slag recycling, including a mounting base 1, on which a processing mechanism for the aluminum ash slag recycling ball mill is provided, the processing mechanism including:

[0025] The support assembly includes a ball mill body 2 mounted on the upper end of a mounting base 1, a support plate 201 fixed to the inner wall of the ball mill body 2, and grinding rods 202 fixed to both ends inside the ball mill body 2.

[0026] The crushing assembly includes a section of the ball mill body 2 with a feed pipe 3 fixed on it. The upper end of the feed pipe 3 is provided with a crushing shell 4. The crushing shell 4 is provided with a crushing shaft 402 inside. The inner wall of the crushing shell 4 is fixed with a fixing bracket 403. One end of the fixing bracket 403 is fixed with a cleaning rod 404. The inner side wall of the crushing shell 4 is provided with an adsorption shell 5. The inner wall of the suction port of the adsorption shell 5 is fixed with a filter screen plate 501.

[0027] In a preferred embodiment, the support plate 201 has a V-shaped structure, and six sets of support plates 201 are evenly arranged along the inner wall of the ball mill body 2. The support plates 201 support and lift the grinding steel balls inside to the top of the ball mill. When the mill rotates, the grinding steel balls can fall from the top and work with the evenly distributed grinding rods 202 inside for grinding. When the ball mill body 2 rotates, the V-shaped support plate 201 lifts the grinding steel balls to the top and then lets them fall freely. Together with the fixed grinding rods 202, they impact and grind the aluminum ash slag, achieving efficient crushing and ensuring that the aluminum ash slag is fully ground, thus improving the recycling effect.

[0028] In a preferred embodiment, the cleaning rod 404 has a gear-shaped structure and is located between the crushing teeth on the outer wall of the crushing shaft 402. The upper end of the crushing shell 4 is fixed with a feeding shell 401, which has a conical structure. A spiral shaft 301 is installed inside the feeding pipe 3. Aluminum ash slag enters the crushing shell 4 from the feeding shell 401. The crushing shaft 402 rotates, driving the crushing teeth to perform preliminary crushing of the aluminum ash slag. The cleaning rod 404 removes material residue between the crushing teeth through the gear-shaped structure to prevent blockage. Through the combined design of the crushing shaft 402 and the cleaning rod 404, not only is pre-crushing achieved, but the crushing teeth can also be automatically cleaned to crush the aluminum ash slag, breaking large pieces of aluminum ash slag into smaller particles, reducing the burden on the subsequent ball mill grinding and improving the efficiency of the entire recycling process.

[0029] Among them, aluminum ash slag enters the crushing shell 4 from the feeding shell 401. The feeding shell 401 has a cone-shaped structure, which facilitates the concentrated entry of materials.

[0030] The crushed aluminum ash slag enters the feed pipe 3, and the spiral shaft 301 inside the feed pipe 3 rotates to transport the material into the ball mill body 2.

[0031] In a preferred embodiment, an adsorption shell 5 extends to one end of the outer side of the crushing shell 4 and is fixed to a collection shell 502. A negative pressure pump 503 is installed on the side wall of the collection shell 502. During the crushing process, the negative pressure pump 503 operates, creating a negative pressure inside the adsorption shell 5. The dust generated from the crushing of aluminum ash slag is filtered through the filter screen 501 at the inlet of the adsorption shell 5 and then drawn into the adsorption shell 5 for collection, reducing dust spillage. The filter screen 501 at the inlet of the adsorption shell 5 can filter large particles of impurities, preventing them from entering the adsorption system. The operation of the negative pressure pump 503 creates a negative pressure inside the adsorption shell 5, drawing the dust generated during the crushing process into the collection shell 502 for collection, effectively reducing dust spillage, improving the working environment, and reducing the health hazards of dust to operators. The negative pressure pump is model VCH1028, which is existing technology and will not be described in detail.

[0032] In a preferred embodiment, the outer shell of the ball mill body 2 has a double-layer structure, and sound insulation cotton 6 is provided between the double-layer structure of the ball mill body 2. The double-layer structure of the outer shell of the ball mill body 2 with sound insulation cotton 6 between the layers can effectively reduce the noise generated during the operation of the ball mill, improve the working environment, and reduce the impact on operators.

[0033] In a preferred embodiment, a mounting plate 7 is provided at the edge of the mounting base 1. The mounting plate 7 has bolts 701 inside for locking with the mounting base 1. Annular brackets 702 are evenly distributed on the upper surface of the mounting plate 7. The ball mill body 2 is located inside the annular brackets 702. The ball mill body 2 is placed on the mounting base 1, and the mounting plate 7 is locked to the mounting base 1 using the bolts 701. The ball mill body 2 is located inside the annular brackets 702 to prevent workers from directly contacting the outside of the ball mill, ensuring safety during operation.

[0034] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0035] During operation, when the aluminum ash slag recycling work begins, the material enters the crushing shell 4 through the cone-shaped feed shell 401. The crushing shaft 402 drives the crushing teeth to perform initial crushing, and the gear-shaped cleaning rod 404 simultaneously removes the residual material between the crushing teeth to prevent blockage. During this process, the negative pressure pump 503 creates a negative pressure in the adsorption shell 5, and the dust generated by crushing is filtered by the filter screen plate 501 and then sucked into the collection shell 502.

[0036] The crushed aluminum ash slag enters the feed pipe 3, and the internal spiral shaft 301 rotates to transport the material into the ball mill body 2. When the ball mill body 2 is running, the V-shaped support plate 201 lifts the grinding steel balls to the top and then lets them fall freely. They cooperate with the grinding rods 202 fixed at both ends to impact and grind the aluminum ash slag. At the same time, the sound insulation cotton 6 between the outer shells of the double-layer structure of the ball mill body 2 effectively reduces the operating noise.

[0037] In addition, the main body 2 of the ball mill is locked and fixed to the mounting base 1 by bolts 701 on the mounting plate 7, and the annular bracket 702 ensures the safety of the operators, ultimately achieving efficient recycling and treatment of aluminum ash slag.
