Description

Technical Field

[0001] This utility model relates to the field of mineral slurry mixing tank technology, and in particular to a mineral slurry mixing tank that is easy to clean. Background Technology

[0002] In the mining and mineral processing process, the slurry mixing tank is a key piece of equipment used for mixing the slurry before flotation operations, so that the slurry and reagents are fully mixed, creating conditions for the flotation operation. It is suitable for various metal ores and is mainly used for mixing before flotation to ensure that the reagents and slurry are fully mixed. It can also be used for mixing other non-metallic minerals.

[0003] However, the slurry is very easy to stick to the inner wall of the mixing tank during the mixing process. If it is not cleaned in time, it will accumulate over time to form a hard scale layer, which will reduce the effective volume of the tank and reduce the mixing efficiency. Although some mixing tanks are equipped with scrapers, the position of the scrapers is usually fixed and cannot be adjusted according to the thickness of the scale, resulting in incomplete cleaning. Therefore, we need to consider how to solve this problem. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a slurry mixing tank that is easy to clean. It is equipped with a sliding ring, a slider, and a scraper, which allows the scraper to switch between being close to or away from the tank wall. This does not interfere with normal mixing, but also allows it to scrape off residues while adhering to the tank wall during cleaning, thus improving the ease of cleaning and the durability of the equipment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A slurry mixing tank that is easy to clean includes a tank body. An annular plate is fixedly connected to the upper end of the tank body. A mounting frame is fixedly connected to the upper end of the annular plate. A motor is mounted on the upper end of the mounting frame. The output shaft of the motor passes through the mounting frame and is fixedly connected to a stirring shaft. Multiple stirring rods are fixedly connected to the outer wall of the stirring shaft. A sliding ring is slidably connected to the outer wall of the stirring shaft. A fixed ring is fixedly connected to the outer wall of the stirring shaft. Fixed plates are fixedly connected to both outer walls of the fixed ring. A sliding groove is formed at the upper end of each of the two fixed plates. The inner walls of the two grooves are slidably connected to sliders. The outer walls of both sides of the sliding ring are rotatably connected to connecting rods. The other ends of the two connecting rods are rotatably connected to the upper ends of the corresponding sliders. The opposite ends of the two sliders are fixedly connected to moving rods. The outer walls of the two moving rods are fitted with springs. The two ends of the two springs are elastically connected to the inner walls of the corresponding grooves and the side walls of the sliders, respectively. The opposite ends of the two moving rods pass through the corresponding fixed plates and are fixedly connected to scrapers. The two scrapers cooperate with the inner walls of the barrel.

[0007] Preferably, a connecting plate is fixedly connected to the upper end of the fixed ring, a movable groove is provided on one side wall of the connecting plate, a threaded rod is rotatably connected between the inner top and inner bottom of the movable groove, and a movable block is threadedly connected to the threaded rod.

[0008] Preferably, one end of the movable block is slidably connected to the inner wall of the movable groove, and the other end of the movable block is fixedly connected to the sliding ring.

[0009] Preferably, the upper end of the threaded rod passes through the connecting plate and is fixedly connected to a worm gear. Two mounting plates are fixedly connected to the upper end of the connecting plate, and a worm is rotatably connected between the two mounting plates. The worm meshes with the worm gear.

[0010] Preferably, one end of the worm gear passes through one of the mounting plates and is fixedly connected to a knob, the outer wall of which is provided with anti-slip texture.

[0011] Preferably, an annular pipe is fixedly connected to the inner wall of the annular plate, a plurality of water outlet pipes are fixedly connected to the lower end of the annular pipe, and a water inlet is opened at the upper end of the annular pipe.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] 1. The structure includes a slider, spring, and scraper. By moving the scraper closer to or away from the barrel wall, the mixing and cleaning functions can be switched. With the help of the elastic force of the spring and the meshing transmission of the worm gear and worm, the scraper can always keep in contact with the barrel wall during cleaning, avoiding cleaning omissions caused by slight deformation or vibration of the barrel wall, thus improving the cleaning effect and the service life of the equipment.

[0014] 2. The structure includes a ring plate, a ring pipe, and water outlet pipes. The ring pipes, in conjunction with multiple water outlet pipes, allow clean water to be sprayed evenly along the circumference of the inner wall of the tank, forming a multi-directional water flow for rinsing. This, combined with the scraper, creates a synergistic cleaning effect of scraping and rinsing, effectively removing any slurry residue scraped off by the scraper, preventing secondary adhesion, and improving cleaning efficiency and thoroughness.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figures 1-8 A slurry mixing tank for easy cleaning includes a tank body 1. An annular plate 2 is fixedly connected to the upper end of the tank body 1. A mounting frame 3 is fixedly connected to the upper end of the annular plate 2. A motor 4, a servo motor, is mounted on the upper end of the mounting frame 3. The output shaft of the motor 4 passes through the mounting frame 3 and is fixedly connected to a stirring shaft 5. Multiple stirring rods 6 are fixedly connected to the outer wall of the stirring shaft 5. A sliding ring 7 is slidably connected to the outer wall of the stirring shaft 5. A fixing ring 8 is fixedly connected to the outer wall of the stirring shaft 5. Fixing plates 9 are fixedly connected to both outer walls of the fixing ring 8. A groove 10 is formed at the upper end of each of the two fixing plates 9. The inner wall is slidably connected to sliders 11, and the outer walls of both sides of the sliding ring 7 are rotatably connected to connecting rods 12. The other ends of the two connecting rods 12 are rotatably connected to the upper ends of the corresponding sliders 11. The opposite ends of the two sliders 11 are fixedly connected to moving rods 13. The outer walls of the two moving rods 13 are fitted with springs 14. The two ends of the two springs 14 are elastically connected to the inner wall of the corresponding slide groove 10 and the side wall of the slider 11, respectively. The elastic force of the springs 14 can ensure that the scraper 15 always keeps in contact with the barrel wall. With the rotation of the stirring shaft 5, the barrel wall is scraped and cleaned, avoiding the problem of difficult cleaning after the slurry has hardened for a long time.

[0026] The two moving rods 13 have opposite ends that pass through corresponding fixed plates 9 and are fixedly connected to scrapers 15. Both scrapers 15 cooperate with the inner wall of the tank 1. Under normal conditions, the equipment can stir the slurry normally. The scrapers 15 can be adjusted to a position away from the tank wall without affecting the flow of the slurry. When cleaning is required, they can be switched to a position that is in contact with the tank wall. The upper end of the fixed ring 8 is fixedly connected to a connecting plate 16. A moving groove 17 is opened on one side wall of the connecting plate 16. The inner top and inner bottom of the moving groove 17 are rotatably connected by threads. The threaded rod 18 is threadedly connected to a movable block 19. One end of the movable block 19 is slidably connected to the inner wall of the movable groove 17, and the other end of the movable block 19 is fixedly connected to the sliding ring 7. The upper end of the threaded rod 18 passes through the connecting plate 16 and is fixedly connected to a worm gear 20. The upper end of the connecting plate 16 is fixedly connected to two mounting plates 21. A worm 22 is rotatably connected between the two mounting plates 21. The worm 22 meshes with the worm gear 20. The transmission between the worm gear 20 and the worm 22 has self-locking properties to ensure stable cleaning effect.

[0027] One end of the worm gear 22 passes through one of the mounting plates 21 and is fixedly connected to a knob 23. The outer wall of the knob 23 is provided with anti-slip texture. When it is necessary to clean the inner wall of the barrel 1, rotating the knob 23 drives the worm gear 22 to rotate. Through the meshing transmission between the worm gear 22 and the worm wheel 20, the threaded rod 18 rotates. The threaded rod 18 drives the moving block 19 to move up and down along the moving groove 17, thereby driving the sliding ring 7 to slide along the stirring shaft 5. The sliding ring 7 pushes the slider 11 to slide in the sliding groove 10 through the connecting rod 12. The movement causes the moving rod 13 to drive the scraper 15 to scrape and clean the inner wall of the barrel 1. The inner side wall of the annular plate 2 is fixedly connected to an annular pipe 24. The lower end of the annular pipe 24 is fixedly connected to multiple water outlet pipes 25. The upper end of the annular pipe 24 is provided with a water inlet 26. The annular pipe 24 is connected to an external water source through the water inlet 26. During cleaning, clean water can be sprayed onto the inner wall of the barrel 1 through multiple water outlet pipes 25. Combined with the scraping action of the scraper 15, a dual cleaning effect of water flushing and scraping is formed, improving cleaning efficiency.

[0028] In this invention, when the inner wall of the barrel 1 needs to be cleaned after stirring, the knob 23 can be turned to rotate the worm 22. Since the worm 22 meshes with the worm wheel 20, the worm 22 will drive the worm wheel 20 to rotate, and the threaded rod 18 will rotate accordingly, causing the moving block 19 to slide along the moving groove 17. The sliding of the moving block 19 will push the sliding ring 7 to move downward along the stirring shaft 5. At this time, the pulling force of the connecting rod 12 on the slider 11 becomes a pushing force, pushing the two sliders 11 to slide in opposite directions in the sliding groove 10. The spring 14 is compressed and generates a reverse elastic force. The slider 11 drives the moving rod 13 to extend away from the stirring shaft 5, so that the two scrapers 15 gradually approach and finally fit tightly against the inner wall of the barrel 1. Since the worm gear 20 and worm 22 transmission have self-locking properties, the threaded rod 18 will not reverse due to the reaction force on the scraper 15, ensuring that the scraper 15 is stably kept in the fitting position. At the same time, the elastic force of the spring 14 can automatically compensate for the gap between the scraper 15 and the barrel wall 1, ensuring a tight fit.

[0029] Subsequently, the motor 4 is started, causing the stirring shaft 5 to drive the fixed ring 8, connecting plate 16 and scraper 15 to rotate as a whole. The rotating scraper 15 will scrape off the slurry residue attached to the inner wall of the tank 1. At the same time, the external water source is connected to the ring pipe 24 through the water inlet 26. The water flows through multiple water outlets 25 at the lower end of the ring pipe 24 and is sprayed onto the inner wall of the tank 1 to rinse off the residue scraped off by the scraper 15. This achieves coordinated cleaning of scraping and water rinsing, ensuring that there is no residue on the tank wall.

[0030] After cleaning is completed, turn the knob 23 in the opposite direction, so that the worm 22 drives the worm wheel 20 and the threaded rod 18 to rotate in the opposite direction, which in turn causes the moving block 19 to move the sliding ring 7 upward. The spring 14 then restores its deformation and pulls the slider 11 back to its original position, while the moving rod 13 drives the scraper 15 to disengage from the inner wall of the tank 1. In this way, the equipment will return to the standby state for stirring operation, waiting for the next stirring or cleaning operation.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
