Description

Technical Field

[0001] This utility model relates to the field of aluminum ash slag screening technology, specifically a screening device for aluminum ash slag reprocessing. Background Technology

[0002] Aluminum, as a widely used metal, plays a crucial role in many fields such as aerospace, automobile manufacturing, and building decoration. During the production, processing, and recycling of aluminum, a large amount of aluminum ash is inevitably generated. Aluminum ash contains not only a certain amount of aluminum but also alumina, aluminum nitride, salts, and other impurities. If aluminum ash is not properly treated and recycled, it will not only cause a serious waste of aluminum resources but also pose numerous environmental hazards.

[0003] In the reprocessing of aluminum ash slag, crushing is a crucial preliminary step. Its purpose is to break large pieces of aluminum ash slag into smaller particles for more efficient subsequent screening and metal recovery. However, due to the complex composition and uneven texture of aluminum ash slag, some fine particles and impurities are easily stuck between the crushing teeth during the crushing process, affecting the normal movement of the crushing teeth and reducing the crushing effect. In addition, aluminum ash slag generates a large amount of dust during crushing and screening. Most existing aluminum ash slag processing equipment lacks effective dust collection and treatment devices, causing dust to spread rampantly in the production workshop. Therefore, this utility model provides a screening device for aluminum ash slag reprocessing. Utility Model Content

This device solves the problem that, due to the complex composition and uneven texture of aluminum ash slag, some fine particles and impurities are easily stuck between the crushing teeth during the crushing process, affecting the normal movement of the crushing teeth and reducing the crushing effect. Furthermore, aluminum ash slag generates a large amount of dust during the crushing and screening process, and most existing aluminum ash slag processing equipment lacks effective dust collection and treatment devices, leading to the problem of dust spreading wantonly in the production workshop.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a screening device for the reprocessing of aluminum ash slag, comprising a support frame, wherein a screening mechanism for the reprocessing of aluminum ash slag is provided on the support frame, the screening mechanism comprising:

[0006] The crushing assembly includes a screening shell fixed to the upper end of a support frame, a conveying shell at one end of the screening shell, a crushing shell fixed to the upper end of the conveying shell, a crushing shaft inside the crushing shell, a fixing rod fixed to the inner wall of the crushing shell, and cleaning rods evenly distributed on the surface of the fixing rod.

[0013] Beneficial effects

[0014] This invention provides a screening device for the reprocessing of aluminum ash slag. Compared with the prior art, it has the following advantages:

[0015] Firstly, this invention features a pair of crushing shafts that rotate under motor drive. The crushing teeth evenly distributed on their outer walls move in an interlacing motion. Under the squeezing and shearing action of the crushing teeth, the aluminum ash slag is gradually crushed into smaller particles, enabling the aluminum ash slag to be crushed into suitable particle sizes more quickly and thoroughly, providing a better material basis for subsequent screening. During the crushing process, since aluminum ash slag may get stuck between the crushing teeth and affect the crushing effect, the cleaning rods fixed on the inner wall of the crushing shell play a role. The cleaning rods are distributed between the crushing teeth. As the crushing shaft rotates, the cleaning rods continuously clean the crushing teeth, preventing aluminum ash slag from sticking and accumulating on the crushing teeth. This ensures that the crushing teeth can always efficiently crush the aluminum ash slag, reducing downtime caused by cleaning the crushing teeth, improving the overall operating efficiency of the equipment, and also extending the service life of the crushing shaft and crushing teeth.

[0016] Secondly, after the dust pump of this utility model is started, a negative pressure environment is formed in the dust collection shell, the third conduit, the first conduit, and the second conduit. The dust collection component effectively solves the dust pollution problem generated during the aluminum ash slag crushing process. By collecting dust in a timely manner, the working environment is improved, the health and safety of operators are protected, the spread of dust in the production workshop is prevented, and the pollution to other equipment is reduced. At the same time, the filter plate ensures that the dust collection pipe will not be blocked by sucking in large particles, thus ensuring the continuous and stable operation of the dust collection component.

[0022] 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.

[0023] Please see Figure 1-4 This utility model provides a technical solution: a screening device for the reprocessing of aluminum ash slag, including a support frame 1, on which a screening mechanism for the reprocessing of aluminum ash slag is provided, the screening mechanism including:

[0024] The crushing assembly includes a screening shell 2 fixed at the upper end of a support frame 1, a conveying shell 201 at one end of the screening shell 2, a crushing shell 202 fixed at the upper end of the conveying shell 201, a crushing shaft 3 inside the crushing shell 202, a fixing rod 301 fixed on the inner wall of the crushing shell 202, and cleaning rods 302 evenly distributed on the surface of the fixing rod 301.

[0025] The dust collection assembly includes a pipe assembly for dust collection between the crushing shell 202 and the screening shell 2. The conveying shell 201 has a spiral conveying shaft 4 inside, and an output shaft 5 is provided at one end of the conveying shaft 4. A flap 501 is fixed to the outer wall of the output shaft 5.

[0026] In a preferred embodiment, the crushing shafts 3 are configured as a pair, with crushing teeth evenly distributed on their outer walls. Cleaning rods 302 are distributed between the crushing teeth. The pair of crushing shafts 3 rotate under the drive of a motor, and the crushing teeth evenly distributed on their outer walls move in an interlacing motion. Under the squeezing and shearing action of the crushing teeth, the aluminum ash slag is gradually crushed into smaller particles, enabling the aluminum ash slag to be crushed into suitable particle size more quickly and thoroughly, providing a better material basis for subsequent screening. During the crushing process, since aluminum ash slag may get stuck between the crushing teeth and affect the crushing effect, the cleaning rods 302 fixed on the inner wall of the crushing shell 202 play a role. The cleaning rods 302 are distributed between the crushing teeth. As the crushing shafts 3 rotate, the cleaning rods 302 continuously clean the crushing teeth, preventing aluminum ash slag from sticking and accumulating on the crushing teeth, ensuring that the crushing teeth can always efficiently crush the aluminum ash slag, reducing downtime caused by cleaning the crushing teeth, improving the overall operating efficiency of the equipment, and also extending the service life of the crushing shafts 3 and the crushing teeth.

[0027] In a preferred embodiment, a feeding shell 203 is fixed to the upper end of the crushing shell 202. The feeding shell 203 has a conical structure and the upper diameter of the feeding shell 203 is smaller than the lower diameter. Aluminum ash slag enters the crushing shell 202 through the feeding shell 203. The conical structure of the feeding shell 203 and the fact that the upper diameter of the feeding shell 203 is smaller than the lower diameter allows the material to fall into the crushing area more concentratedly.

[0028] One pair of crushing shafts 3 is driven by a motor and two sets of gears, as detailed in [reference needed]. Figure 2 As shown.

[0029] In a preferred embodiment, the pipeline assembly includes a first conduit 7 disposed at the upper end of the screening shell 2, a second conduit 701 penetrating through the side wall of the crushing shell 202, and a filter plate 7011 fixed at one end of the second conduit 701 inside the crushing shell 202 at the dust suction port. The second conduit 701 and the first conduit 7 are fixedly connected, and a third conduit 703 is fixed at the connection between the second conduit 701 and the first conduit 7. A dust suction shell 702 is fixed to one side wall of the crushing shell 202, and a dust suction pump 704 is disposed on one side of the dust suction shell 702. The other end of the third conduit 703 is in flow connection with the dust suction shell 702. After the dust suction pump 704 is started, a negative pressure environment is formed in the dust suction shell 702, the third conduit 703, the first conduit 7, and the second conduit 701. Inside the crushing shell 202, the dust generated during the crushing of aluminum ash slag passes through the second conduit 701 under the action of negative pressure. The filter plate 7011 located at one end of the dust suction port inside the crushing shell 202 enters the second conduit 701. The filter plate 7011 prevents larger particles from being sucked into the dust suction pipe, avoiding pipe blockage. The dust sucked into the second conduit 701 enters the third conduit 703 fixed at the connection between the second conduit 701 and the first conduit 701 through the first conduit 701, and is then transported to the dust suction shell 702 through the third conduit 703. The dust suction component effectively solves the dust pollution problem generated during the aluminum ash slag crushing process. By collecting dust in a timely manner, the working environment is improved, the health and safety of operators are protected, the spread of dust in the production workshop is prevented, and pollution to other equipment is reduced. At the same time, the filter plate 7011 ensures that the dust suction pipe will not be blocked by sucking in larger particles, ensuring the continuous and stable operation of the dust suction component.

[0030] In a preferred embodiment, a filter cylinder 6 is horizontally fixed inside the screening housing 2. The output shaft 5 and the flap 501 are located inside the filter cylinder 6, with the flap 501 slidingly connected to the inner wall of the filter cylinder 6. The conveying shaft 4 feeds the crushed material into the filter cylinder 6. A discharge housing 602 for filtering and discharging material from the filter cylinder 6 is provided at the lower end of the screening housing 2. A discharge pipe 601 is provided at the other end of the screening housing 2. An opening and closing housing 8 is rotatably connected to the outer wall surface of the screening housing 2 via a rotating shaft. One end of the opening and closing housing 8 is detachably connected to the screening housing 2 via bolts. The conveying shaft 4... The crushed aluminum ash slag is fed into the filter cylinder 6. The output shaft 5 drives the flap 501 to rotate inside the filter cylinder 6. The flap 501 slides against the inner wall of the filter cylinder 6. Under the tumbling action of the flap 501, smaller particles of the aluminum ash slag fall through the filter screen of the filter cylinder 6 into the discharge shell 602 below, while larger particles move along the inner wall of the filter cylinder 6 and are finally discharged through the discharge pipe 601. The cooperation between the filter cylinder 6 and the flap 501 achieves effective screening of the aluminum ash slag. The tumbling action of the flap 501 causes the aluminum ash slag to tumble continuously inside the filter cylinder 6, increasing the contact opportunity between the material and the filter screen, and improving screening efficiency and accuracy.

[0031] When it is necessary to clean, maintain or repair the inside of the screening shell 2, loosen the bolts connecting one end of the opening and closing shell 8 to the screening shell 2, rotate the opening and closing shell 8 by rotating the shaft to expose the inside of the screening shell 2, so that the operator can carry out relevant operations. After the operation is completed, rotate the opening and closing shell 8 back to its original position and fix it with bolts.

[0032] Additional notes: The aforementioned conveyor shaft 4 is driven by a motor; please refer to [link / reference needed] for details. Figure 2 As shown.

[0033] The motors mentioned above are servo motors with the model number EDSMT-2T110-020A, and the dust pumps are models HG010-12AD1. Both are existing technologies and will not be discussed in detail.

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

[0035] During operation, aluminum ash enters the crushing shell 202 through a cone-shaped feed shell 203 with an upper diameter smaller than the lower diameter. Inside the crushing shell 202, a pair of crushing shafts 3 rotate under the drive of a motor and two sets of gears. The crushing teeth evenly distributed on the outer wall of the shafts move in an interlacing motion. Under the squeezing and shearing action of the crushing teeth, the aluminum ash is gradually crushed into smaller particles. At the same time, the cleaning rods 302, which are fixed on the fixing rods 301 on the inner wall of the crushing shell 202, are distributed between the crushing teeth. As the crushing shafts 3 rotate, they continuously clean the crushing teeth to prevent the aluminum ash from sticking and accumulating.

[0036] The crushed aluminum ash falls into the conveying shell 201, and the spiral conveying shaft 4 inside conveys it to the horizontally fixed filter cylinder 6 inside the screening shell 2. The output shaft 5 at one end of the conveying shaft 4 drives the flap 501 to rotate inside the filter cylinder 6. The flap 501 slides against the inner wall of the filter cylinder 6, causing the aluminum ash to tumble continuously. Smaller particles fall through the filter screen of the filter cylinder 6 into the discharge shell 602 below, while larger particles move along the inner wall of the filter cylinder 6 and are discharged through the discharge pipe 601.

[0037] Throughout the process, after the dust pump 704 starts, a negative pressure is formed in the dust collection housing 702, the third conduit 703, the first conduit 7, and the second conduit 701. The dust generated by the crushing is filtered by the filter plate 7011 at the dust collection port of the second conduit 701, and then enters the dust collection housing 702 for collection in sequence through the second conduit 701, the first conduit 7, and the third conduit 703. When it is necessary to clean, maintain, or repair the inside of the screening housing 2, loosen the bolt connecting one end of the opening and closing housing 8 to the screening housing 2, and rotate the opening and closing housing 8 by rotating the rotating shaft to expose the inside. After the operation is completed, return it to its original position and fix it with bolts.
