Description

Technical Field

[0001] This utility model relates to the field of electrolytic aluminum waste residue recycling technology, and in particular to an electrolytic aluminum waste residue recycling device. Background Technology

[0002] A certain amount of waste slag is generated during the electrolytic aluminum processing, and this waste slag has recycling value. The aluminum slag produced during electrolysis floats on the surface of the molten aluminum in the electrolytic cell. Its main components include unreacted alumina, cryolite, and other raw materials and mixtures, as well as trace impurities produced by the chemical reactions of additives and debris formed from the shedding of anode and cathode materials. To improve the recycling efficiency, the waste slag must first be crushed to optimize collection.

[0003] In actual production, it has been found that when a crusher continuously processes electrolytic aluminum slag for extended periods, the raised structures on the surface of the crushing rollers are prone to wear and flattening. This phenomenon directly leads to an increase in the particle size of the crushed electrolytic aluminum slag, thus affecting the efficiency of subsequent recycling and processing. Moreover, the crusher currently in use adopts an integrated design for its casing. This structure makes it difficult to perform targeted repairs on locally worn crushing rollers, which not only increases equipment maintenance costs but may also affect production efficiency due to equipment downtime. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following solution: This utility model provides an electrolytic aluminum waste slag recycling device, including a shell, a crushing roller, and a driving device. The crushing roller is installed inside the shell. The shell includes a first spliced ​​shell and a second spliced ​​shell, which are detachably connected. After the first spliced ​​shell and the second spliced ​​shell are connected, they form an accommodating space for accommodating the crushing roller. The driving device is connected to the crushing roller and is used to drive the crushing roller to rotate.

[0006] Preferably, the splicing end of the first splicing shell has a protrusion, and the splicing end of the second splicing shell has a groove that matches the protrusion.

[0011] Preferably, it also includes a support leg, which is fixedly connected to the bottom of the housing.

[0012] Preferably, the device further includes a clamping device comprising two clamping members symmetrically mounted on the support leg. Each clamping member includes a U-shaped groove, a sliding plate, a damper, and a clamping plate. The U-shaped groove is fixedly connected to the support leg, and the sliding plate is slidably connected to the U-shaped groove. The sliding plate is fixedly connected to the clamping plate via the damper. The side of the clamping plate away from the damper is an arc-shaped surface. The clamping plates of the two clamping members can clamp and fix the collection frame for collecting crushed waste residue.

[0019] 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.

[0020] The purpose of this invention is to provide an electrolytic aluminum waste slag recycling device to solve the problems existing in the prior art, facilitate the maintenance of worn crushing rollers, ensure the crushing particle size of the waste slag, and improve production efficiency.

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] This utility model provides a device for recycling electrolytic aluminum waste residue, such as... Figures 1-2As shown, the device includes a housing, a crushing roller 3, and a drive unit 4. The crushing roller 3 is installed inside the housing, which comprises a first splicing housing 1 and a second splicing housing 2. The first splicing housing 1 and the second splicing housing 2 are detachably connected. When connected, the first splicing housing 1 and the second splicing housing 2 form a space for accommodating the crushing roller 3. The drive unit 4 is connected to the crushing roller 3 and is used to drive the crushing roller 3 to rotate. The housing adopts a modular split design, consisting of the first splicing housing 1 and the second splicing housing 2 connected by a quick-disassembly structure. When the raised structure on the surface of the crushing roller 3 wears due to long-term operation, the worn crushing roller 3 can be quickly exposed by disassembling the first splicing housing 1 and the second splicing housing 2, facilitating timely maintenance and polishing. After repair, only the two splicing housings need to be reassembled to quickly restore the normal operation of the equipment. This solves the maintenance problems of traditional integrated housing crushers, effectively avoids the problem of increased particle size of electrolytic aluminum waste slag caused by the failure to promptly address the wear on the surface of the crushing roller 3, significantly improves the maintainability of the equipment, and ensures a stable increase in recycling efficiency. Preferably, the top of the housing is provided with a feed inlet 21, and the bottom of the housing is provided with a discharge outlet 22. The drive device 4 is a Y80~315 motor, and there are two crushing rollers 3, which are fixedly connected to two Y80~315 motors respectively. When it is necessary to recycle electrolytic aluminum waste, electrolytic aluminum is poured into the housing space through the feed inlet 21. The Y80~315 motor is started, and the crushing rollers 3 are driven to rotate under the action of the coupling at the output end of the Y80~315 motor, thereby crushing the electrolytic aluminum. The crushed electrolytic aluminum falls out from the discharge outlet 22 for recycling.

[0023] A further preferred embodiment of this utility model is, as follows: Figure 3 As shown, the splicing end of the first splicing housing 1 has a protrusion 5, and the splicing end of the second splicing housing 2 has a groove 6 that matches the protrusion 5. The first splicing housing 1 and the second splicing housing 2 achieve precise positioning and rapid connection through the fitting of the protrusion 5 and the groove 6.

[0024] In a further preferred embodiment of this utility model, the end face of the protrusion 5 away from the first splicing shell 1 is fixedly connected to an iron sheet 7, and the bottom surface of the groove 6 is fixedly connected to a magnetic plate 8. Through the magnetic attraction between the magnetic plate 8 and the iron sheet 7, the problem of laborious disassembly and assembly in traditional purely mechanical connections is solved, while ensuring the structural stability of the assembled shells. This design is suitable for industrial equipment scenarios requiring frequent maintenance.

[0025] In a further preferred embodiment of this invention, a buffer washer is fixedly connected to the end of the groove 6 away from the second splicing housing 2. When the first splicing housing 1 and the second splicing housing 2 are joined, the buffer washer can absorb the assembly impact during the joining process, preventing rigid collisions. While ensuring quick assembly and disassembly, it also improves the equipment's resistance to vibration and impact, extending the service life of the housing connection parts. Preferably, the buffer washer is a silicone washer.

[0026] In a further preferred embodiment of this utility model, a first through hole is provided on one side wall of the groove portion 6, and a threaded hole matching the first through hole is provided on the protrusion portion 5. After the protrusion portion 5 is inserted into the groove portion 6, the bolt 9 can pass through the first through hole and be threadedly connected to the threaded hole. A washer 10 is provided between the bolt 9 and the groove portion 6. The bolt 9 can firmly fix the protrusion portion 5 and the groove portion 6, preventing loosening or relative displacement after assembly, ensuring the connection strength of the overall structure, and resisting external forces such as vibration and impact generated during equipment operation. The washer 10 can prevent the bolt 9 from being overloaded on the surface of the crusher and facilitate the disassembly and installation of the bolt 9. Preferably, the washer 10 is a rubber ring.

[0027] Preferably, one end of the crushing roller 3 is fixedly connected to the second splicing housing 2, and the other end of the crushing roller 3 overlaps the first splicing housing 1. The drive device 4 is installed on the second splicing housing 2. When it is necessary to grind the worn protrusions on the surface of the crushing roller 3, first unscrew the bolt 9, then pull the first housing and the second housing to both sides to pull the protrusion 5 out of the groove 6, thus exposing the crushing roller 3, which facilitates the repair and grinding of the crushing roller 3.

[0028] A further preferred embodiment of this utility model is, as follows: Figure 4As shown, the electrolytic aluminum waste recycling device also includes a support leg 11 and a clamping device 12. The support leg 11 is fixedly connected to the bottom of the shell. The clamping device 12 includes two clamping components symmetrically mounted on the support leg 11. The clamping components include a U-shaped chute 13, a sliding plate 14, a damper 15, and a clamping plate 16. The U-shaped chute 13 is fixedly connected to the support leg 11, and the openings of the two U-shaped chute 13 are opposite to each other. The sliding plate 14 is slidably connected to the U-shaped chute 13. The sliding plate 14 is fixedly connected to the clamping plate 16 through the damper 15. The side of the clamping plate 16 away from the damper 15 is an arc-shaped surface. The clamping plates 16 of the two clamping components can clamp and fix the collection frame that collects the crushed waste residue. The two clamping plates 16 apply a uniform clamping force through the damper 15, so that the collection frame can be firmly fixed below the discharge port 22 of the shell, ensuring that the waste residue falls smoothly into the collection frame. Once the collection box is full, simply pull out the slide plate 14. The slide plate 14 moves the clamping plate 16 along the U-shaped groove 13, easily removing the collection box from the bottom of the housing. This achieves stable fixation and convenient removal of the collection box. The arc-shaped surface design of the clamping plate 16 better matches the shape of the collection box, increasing the contact area, improving clamping stability, and preventing the collection box from shaking or shifting. Preferably, the bottom of the U-shaped groove 13 has a reinforcing plate 19 to enhance the robustness of the U-shaped groove 13.

[0029] In a further preferred embodiment of this invention, a rubber strip 17 is provided on the arc-shaped surface. The rubber strip 17 can increase the friction between the arc-shaped surface and the collecting frame, prevent the collecting frame from sliding, and ensure clamping stability.

[0030] In a further preferred embodiment of this utility model, the clamping device 12 further includes a fixing pin 18. A second through hole is provided on one side wall of the U-shaped slide groove 13, and a slot 20 matching the second through hole is provided on the slide plate 14. After the slide plate 14 is inserted into the U-shaped slide groove 13, the fixing pin 18 can pass through the second through hole and insert into the slot 20. The fixing pin 18 mechanically locks the position of the slide plate 14 in the U-shaped slide groove 13, ensuring that the clamping plate 16 remains stable when clamping the collection frame, preventing the slide plate 14 from moving accidentally due to external force, thus affecting the fixing effect of the collection frame.
