Description

Technical Field

[0001] This utility model relates to the field of red mud treatment technology, specifically to a device for treating red mud. Background Technology

[0002] Red mud treatment involves a series of processes and disposals of red mud generated during aluminum industry production to achieve its resource utilization and reduce environmental pollution and ecological damage. Red mud does indeed need to be stirred and mixed before it can be utilized for resource utilization or further treatment.

[0003] When the existing equipment is in use, it only uses a simple agitator to stir the red mud, which lacks sufficient stirring force and mixing efficiency, resulting in excessively long stirring time, increased energy consumption, and reduced mixing capacity.

[0004] To overcome the aforementioned deficiencies, existing technology (Chinese patent application number: 202321995628.0, application date: July 27, 2023) discloses a treatment device for reducing the sodium oxide content of red mud. This treatment device is connected to multiple stirring shafts through a transmission assembly. A motor drives multiple stirring shafts to revolve around the central axis through the transmission assembly, and at the same time, the motor drives multiple stirring shafts to rotate independently through the transmission assembly. Inside the tank, a guide assembly is provided to drive multiple stirring shafts to continuously move up and down. When the telescopic sleeve revolves, the guide rod moves along the guide groove, which is a wave-shaped groove with up and down undulations. In this way, the telescopic sleeve moves up and down due to the up and down movement of the guide rod. When the stirring shaft rotates and stirs the red mud and lime, it also moves up and down continuously, thus mixing the upper and lower layers of red mud and lime.

[0005] While existing technologies can solve the problem of mixing red mud and lime, the presence of lumps or particles in the red mud can lead to uneven mixing when directly mixed via a stirring shaft, reducing the effectiveness of the mixing. Furthermore, red mud and lime tend to remain or adhere to the inner wall of the device during the mixing process, making them difficult to scrape off, increasing cleaning work, reducing the efficiency of the device, and making it impossible to disassemble and clean the device.

[0006] Therefore, we proposed a device for treating red mud that can effectively solve the above problems. Utility Model Content

[0007] The purpose of this utility model is to provide a device for treating red mud, in order to solve the problems mentioned in the background art. When using the current treatment device, because there are lumps or particles in the red mud, direct mixing by the stirring shaft may lead to uneven mixing, reducing the mixing effect of red mud and lime. In addition, red mud and lime are easy to remain or adhere to the inner wall of the device during the mixing process, which cannot be scraped off, increasing the cleaning work, reducing the efficiency of the device, and making it impossible to disassemble and clean the device.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a device for treating red mud, comprising a treatment tank, feeding pipes fixedly installed on the top of both sides of the treatment tank, a sealing cover detachably connected to the top of the treatment tank, a crushing box provided on the top of the sealing cover, and guide plates fixedly installed on the top of both sides of the crushing box.

[0013] As a preferred technical solution of this application, there are two guide plates, both of which are set as sloping plates. When the red mud to be processed is poured into the crushing box by the workers, the slope of the guide plates guides the red mud, so that the red mud can slide down into the crushing box evenly.

[0014] As a preferred technical solution of this application, the outer wall of the rotating rod is fitted with a first gear behind the sealing cover. The left side of the first gear is meshed with a second gear, and the inside of the second gear is fixedly connected to a fixed rod. The outer wall of the fixed rod is fitted with a second crushing roller. During the rotation of the rotating rod, the first gear is driven to rotate. Through the meshing and rotation of the first gear and the second gear, the second gear drives the second crushing roller connected to the fixed rod to rotate in close proximity to the first crushing roller.

[0015] As a preferred technical solution of this application, the stirring rod is fixedly connected to the stirring blade and the scraper, and the stirring blade is configured with a structure of different lengths, and the scraper is configured with an arc-shaped structure. By configuring several stirring blades with different lengths, the red mud and slurry or water in the treatment tank can be thoroughly stirred to ensure uniform mixing.

[0016] As a preferred technical solution of this application, the slide plate and the fixed cylinder are movably connected, and the slide plate and the locking rod and the telescopic rod are tightly fitted together.

[0031] 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.

[0032] Please see Figures 1-6 The present invention provides the following technical solution:

[0033] Example 1: To address the issues in commercially available treatment devices where the presence of lumps or particles in the red mud can lead to uneven mixing via a stirring shaft, reducing the effectiveness of the red mud and lime mixture, and causing residues or adhesions to the inner walls of the device that are difficult to scrape off, increasing cleaning work and reducing the device's efficiency, please refer to the attached... Figure 1 - Appendix Figure 5 The system includes a processing tank 1, with feed pipes 2 fixedly installed on the top of both sides of the processing tank 1. A sealing cover 3 is detachably connected to the top of the processing tank 1, and a crushing box 4 is installed on the top of the sealing cover 3. Guide plates 5 are fixedly installed on the top of both sides of the crushing box 4. A servo motor body 6 is installed at the rear right side of the crushing box 4. A rotating rod 7 is fixedly installed on the output shaft of the servo motor body 6 through a coupling. A first crushing roller 8 is fixedly installed on the outer wall of the rotating rod 7. A rotating motor body 11 is installed at the bottom of the processing tank 1. A stirring rod 12 is fixedly installed on the output shaft of the rotating motor body 11 through a coupling. Several stirring blades 13 are provided on the outer wall of the stirring rod 12. Three scraper blades 14 are fixedly installed on the outer wall of the stirring rod 12. Slots are provided on the front and rear sides of the processing tank 1. There are two guide plates 5, and both guide plates 5 are set as inclined plates. A first gear is fitted on the outer wall of the rotating rod 7 behind the sealing cover 3. A second gear is meshed with the left side of the first gear, and a fixing rod 10 is fixedly connected inside the second gear. A second crushing roller 9 is fitted and fixedly connected to the outer wall of the fixing rod 10. The stirring rod 12 is fixedly connected to the stirring blade 13 and the scraper 14. The stirring blade 13 is configured with a structure of different lengths, and the scraper 14 is configured with an arc-shaped structure.

[0034] The red mud to be processed is poured into the crushing box 4 by the staff. The slope of the guide plate 5 guides the red mud to flow evenly into the crushing box 4. With the help of the external control board, the servo motor body 6 is started, and the output shaft of the servo motor body 6 drives the rotating rod 7 to rotate. The rotating rod 7 drives the first crushing roller 8. During the rotation of the rotating rod 7, the first gear is driven to rotate. Through the meshing and rotation of the first gear and the second gear, the second gear drives the second crushing roller 9 connected to the fixed rod 10 to rotate close to the first crushing roller 8. Thus, the second crushing roller 9 and the first crushing roller 8 crush the incoming red mud, thereby crushing the red mud and providing uniform particle size for subsequent mixing.

[0035] The crushed red mud falls to the bottom of the crushing box 4 and then enters the processing tank 1 through the connecting pipe. The staff adds the required amount of mud or water into the processing tank 1 through the feed pipe 2. The rotating motor body 11 is started by the external control board, which drives the stirring rod 12 and several stirring blades 13 to rotate. The stirring blades 13 are set with different lengths to thoroughly stir the red mud and mud or water in the processing tank 1, ensuring uniform mixing. During the rotation of the stirring rod 12, the connected scraper 14 is also rotated, which scrapes off the red mud that is left or adhered inside the processing tank 1, reducing cleaning work, improving the efficiency of the device, and realizing efficient mixing and treatment of red mud.

[0036] Example 2: The sealing cap 3 can be disassembled; please refer to the attached document. Figure 1 - Appendix Figure 2 A discharge pipe 15 is fixedly connected to the bottom right side of the treatment tank 1. A connecting pipe 16 is connected to the flange on the right side of the discharge pipe 15. A sludge pump body 17 is installed on the right side of the connecting pipe 16. Mounting plates 18 are fixedly installed on the bottom of the front and rear sides of the treatment tank 1. A fixing cylinder 19 is fixedly installed on the front of the mounting plate 18. A sliding plate 20 is movably connected inside the fixing cylinder 19. A locking rod 21 is fixedly installed on the rear of the sliding plate 20. A telescopic rod 22 is fixedly installed on the front of the sliding plate 20. A spring 23 is sleeved on the outer wall of the telescopic rod 22. The sliding plate 20 and the fixing cylinder 19 are movably connected, and the sliding plate 20, locking rod 21, and telescopic rod 22 are tightly fitted together. The locking rod 21 and the locking groove are detachably connected.

[0037] After the red mud mixing process is completed, the external control board starts the mud pump body 17, which extracts the mixed red mud slurry in the treatment tank 1 through the discharge pipe 15 and the connecting pipe 16. After the device is used, when it is necessary to clean or repair the device, the discharge pipe 15 and the connecting pipe 16 connected by the flange are manually disassembled, so that the mud pump body 17 can be disassembled. Then, the operator manually pulls the two telescopic rods 22 outward, so that the telescopic rods 22 move the sliding plate 20 outward in the corresponding fixed cylinder 19. During the outward movement of the sliding plate 20, the spring 23 is squeezed to increase the stability and elasticity of the sliding plate 20. Thus, the sliding plate 20 drives the locking rod 21 to move outward and disengage from the corresponding locking groove. When the locking rod 21 is completely disengaged from the locking groove, the fixing between the sealing cover 3 and the treatment tank 1 is released. At this time, the operator can manually move the sealing cover 3 upward to disengage it from the treatment tank 1, so as to disassemble the sealing cover 3. This facilitates the operator's cleaning or repair work on the device, improves the maintainability and service life of the device.
