Abstract
Description
Technical Field
[0001] This utility model relates to the field of centrifugal washing technology, and in particular to an integrated centrifugal washing device using a hydrotalcite-like material. Background Technology
[0002] Hydrotalcite-like materials (TLS) are a class of inorganic materials with a layered crystal structure. Due to their unique interlayer exchangeability, high specific surface area, good thermal stability, and catalytic performance, these materials are widely used in catalyst supports, adsorbents, ion exchangers, flame retardants, and other fields. In the industrial production of TLS, the reaction products need to be washed to remove residual electrolytes, unreacted raw materials, and byproducts to ensure product purity meets application requirements. Centrifugal washing is a key technology for achieving this process. Currently, the equipment used industrially for centrifugal washing of TLS is mainly the three-legged centrifuge. Its core working component is the drum, with densely perforated mesh on its sidewalls. During operation, a drive device rotates the drum at high speed, using centrifugal force to force the liquid in the TLS slurry through the mesh and filter cloth, while solid particles are retained inside the drum, achieving solid-liquid separation and washing. During the washing process, washing water is usually continuously introduced into the drum, and centrifugal force completes the rinsing of solid particles, ultimately yielding a cleaned TLS product.
[0003] However, in practical applications, the hydrotalcite-like particles themselves are nano- to micron-sized and have strong agglomeration characteristics. Under centrifugal force, some fine particles easily embed themselves into the drum mesh during liquid flow. Simultaneously, residual electrolytes, unreacted raw materials, and other impurities in the slurry combine with the particles on the mesh surface to form scale, leading to mesh blockage. Once the mesh is blocked, the liquid filtration channel narrows, the filtration rate drops significantly, and the centrifugal washing cycle is prolonged, reducing production efficiency. Therefore, regular cleaning of the drum mesh is crucial for ensuring stable equipment operation. However, existing three-legged centrifuges often have numerous mesh openings on the sidewalls of the drum to ensure solid-liquid separation efficiency. When a large number of mesh openings become blocked, manually brushing or high-pressure washing to clean each opening is not only cumbersome but also time-consuming. Therefore, this application proposes an integrated hydrotalcite-like centrifugal washing device to solve the above problems. Utility Model Content
[0004] The main purpose of this utility model is to provide a hydrotalcite-based centrifugal washing integrated device that can effectively solve the problems in the background technology.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A hydrotalcite-based centrifugal washing integrated device includes a base, an outer shell fixedly mounted on the upper end of the base, a rotating drum rotatably mounted above the base and inside the outer shell, a mounting frame fixedly mounted on the upper end of the outer shell, the mounting frame consisting of a rectangular frame, a mounting plate, and an internally threaded tube, two of which are symmetrically fixedly mounted on the left and right ends of the rectangular frame, the internally threaded tube being fixedly inserted into the outer wall of the rectangular frame, an adjusting component mounted on the mounting frame, the adjusting component consisting of a moving plate, limiting blocks, a lead screw, and a handle, two of which are symmetrically fixedly mounted on the left and right ends of the moving plate, the lead screw being rotatably mounted on the outer end of the moving plate, and the handle being fixedly mounted on the outer end of the lead screw, a cleaning component movably mounted on the outer shell and the moving plate, the cleaning component consisting of a rotating roller, hard bristles, a rotating shaft, and limiting rings, the hard bristles being fixedly mounted on the outer wall of the rotating roller, the rotating shaft being fixedly mounted on the upper end of the rotating roller, and two limiting rings, both fixedly sleeved on the rotating shaft.
[0006] Preferably, the base is fixedly installed on the bottom bracket, a water outlet pipe is fixedly inserted into the base, and a drive device is also fixedly installed on the base. A first guide rail groove is provided on the upper side wall of the outer shell, and the drum is fixedly connected to the output shaft of the drive device.
[0007] Preferably, the rectangular frame on the mounting bracket is fitted outside the first guide rail through groove, the mounting plate is fixedly installed on the upper end of the outer shell by bolts, two second guide rail through grooves are symmetrically opened on the left and right side walls of the rectangular frame, and through holes are opened on the outer side wall of the rectangular frame, and the internally threaded tube is fixedly inserted into the through holes.
[0008] Preferably, the movable plate on the adjusting member is slidably installed in the rectangular frame, the movable plate has a shaft hole, the inner wall of the shaft hole has an annular anti-detachment groove, the limiting block is slidably installed in the second guide rail through groove, the lead screw is installed in the internal threaded tube, and the handle is located on the outside of the internal threaded tube.
[0009] Preferably, the cleaning component is located outside the drum, and the rotating roller on the cleaning component and the lower limiting ring are both located inside the housing. The rotating shaft passes upward through the first guide rail groove and the shaft hole, and the upper limiting ring is rotatably installed in the annular anti-detachment groove.
[0010] Compared with the prior art, the present invention has the following beneficial effects: A mounting frame consisting of a rectangular frame, a mounting plate, and an internally threaded tube is installed on the outer casing. An adjusting component consisting of a movable plate, a limiting block, a lead screw, and a handle is installed on the mounting frame. A cleaning assembly consisting of a rotating roller, stiff brush bristles, a rotating shaft, and a limiting ring is installed on the adjusting component and the outer casing. Rotating the handle drives the lead screw to rotate within the internally threaded tube, which in turn pushes the movable plate to slide along the second guide rail groove within the rectangular frame. The movable plate then drives the rotating shaft of the cleaning assembly to move along the first guide rail groove, thereby adjusting the distance between the rotating roller and the outer wall of the drum, ensuring the stiff brush bristles are tightly fitted to the drum surface. Then, when the drive device rotates the roller... When the drum rotates, the friction between the drum and the cleaning component causes the cleaning component to rotate on the moving plate. At this time, the hard bristles on the outer wall of the roller can insert into the mesh holes on the side wall of the drum, thereby effectively removing the small hydrotalcite particles embedded in the mesh holes and surface scale. The whole process does not require manual cleaning of the clogged mesh holes one by one, which simplifies the operation process, greatly shortens the cleaning time, and improves cleaning efficiency. Moreover, the position of the cleaning component can be flexibly adjusted. When washing hydrotalcite, it does not need to contact the drum, thereby avoiding the presence of the cleaning component increasing the resistance of the drum rotation, making the cleaning component more practical.

[0013] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0014] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, a hydrotalcite-like centrifugal washing integrated device includes a base 1, a housing 2 fixedly mounted on the upper end of the base 1, a drum 3 rotatably mounted above the base 1 and inside the housing 2, and a mounting frame 4 fixedly mounted on the upper end of the housing 2. The mounting frame 4 consists of a rectangular frame 11, a mounting plate 12, and an internally threaded tube 15. There are two rectangular frames 11, symmetrically fixedly mounted on the left and right ends of the rectangular frame 11. The internally threaded tube 15 is fixedly inserted into the outer wall of the rectangular frame 11. An adjusting component 5 is mounted on the mounting frame 4. The adjusting component 5 consists of a moving plate 16, a limiting block 19, a lead screw 20, and a handle 21. The limiting block 19 has... Two symmetrically fixed components are mounted on the left and right ends of the movable plate 16. A lead screw 20 is rotatably mounted on the outer end of the movable plate 16. A handle 21 is fixedly mounted on the outer end of the lead screw 20. A cleaning assembly 6 is movably mounted on the outer casing 2 and the movable plate 16. The cleaning assembly 6 consists of a rotating roller 22, stiff bristles 23, a rotating shaft 24, and limiting rings 25. The stiff bristles 23 are fixedly mounted on the outer wall of the rotating roller 22. The rotating shaft 24 is fixedly mounted on the upper end of the rotating roller 22. There are two limiting rings 25, both fixedly sleeved on the rotating shaft 24. A mounting bracket 4, consisting of a rectangular frame 11, a mounting plate 12, and an internally threaded tube 15, is provided on the outer casing 2 for installation... The frame 4 is equipped with an adjusting component 5 consisting of a movable plate 16, a limiting block 19, a lead screw 20, and a handle 21. A cleaning assembly 6 consisting of a rotating roller 22, stiff brush bristles 23, a rotating shaft 24, and a limiting ring 25 is mounted on the adjusting component 5 and the outer casing 2. Rotating the handle 21 drives the lead screw 20 to rotate within the internally threaded tube 15, thereby pushing the movable plate 16 to slide along the second guide rail groove 13 within the rectangular frame 11. The movable plate 16 drives the rotating shaft 24 of the cleaning assembly 6 to move along the first guide rail groove 10, thus adjusting the distance between the rotating roller 22 and the outer wall of the drum 3, ensuring that the stiff brush bristles 23 are tightly fitted to the surface of the drum 3. Then, when the driving device 9 drives the rotating roller 22... When drum 3 rotates, the friction between drum 3 and cleaning component 6 will cause cleaning component 6 to rotate on moving plate 16. At this time, the hard bristles 23 on the outer wall of roller 22 can be inserted into the mesh holes on the side wall of drum 3, thereby effectively removing small particles of hydrotalcite embedded in the mesh holes and surface scale. The whole process does not require manual cleaning of the clogged mesh holes one by one, which simplifies the operation process, greatly shortens the cleaning time, and improves cleaning efficiency. Moreover, the position of cleaning component 6 can be flexibly adjusted. When washing hydrotalcite, it does not need to contact drum 3, thereby avoiding the presence of cleaning component 6 increasing the resistance of drum 3 rotation, making cleaning component 6 more practical.
[0015] Specifically, the base 1 is fixedly installed on the bottom support 7, and a water outlet pipe 8 is fixedly inserted into the base 1. A drive device 9 is also fixedly installed on the base 1. A first guide rail groove 10 is provided on the upper side wall of the outer casing 2. The drum 3 is fixedly connected to the output shaft of the drive device 9. During centrifugal washing of the hydrotalcite-like material, a filter cloth is first placed inside the drum 3, then the hydrotalcite-like slurry is added inside the drum 3. The drive device 9 fixedly installed on the base 1 is then started. The output shaft of the drive device 9 drives the drum 3 to rotate at high speed inside the outer casing 2, utilizing centrifugal force. The liquid in the hydrotalcite slurry is passed through the filter cloth and the mesh on the side wall of the drum 3 and thrown into the outer shell 2. The thrown liquid is finally discharged through the water outlet pipe 8 fixedly inserted on the base 1, while the solid hydrotalcite particles are trapped in the drum 3. Then, washing water is continuously introduced into the drum 3. Under the action of centrifugal force, the washing water washes the solid hydrotalcite particles in the drum 3. The above solid-liquid separation and washing process is repeated until the purity of the hydrotalcite product meets the requirements. After the centrifugal washing is completed, the drive device 9 is turned off, the drum 3 is stopped from rotating, and the washed hydrotalcite product is taken out.
[0016] Specifically, the rectangular frame 11 on the mounting bracket 4 is fitted onto the outside of the first guide rail groove 10. The mounting plate 12 is fixedly installed on the upper end of the outer casing 2 by bolts. Two second guide rail grooves 13 are symmetrically opened on the left and right side walls of the rectangular frame 11. A through hole 14 is opened on the outer wall of the rectangular frame 11. The internally threaded tube 15 is fixedly inserted into the through hole 14. The moving plate 16 on the adjusting component 5 is slidably installed in the rectangular frame 11. A shaft hole 17 is opened on the moving plate 16. An annular anti-detachment groove 18 is opened on the inner wall of the shaft hole 17. The limiting block 19 is slidably installed in the second guide rail groove 13. The lead screw 2 0 is installed inside the internal threaded tube 15, with the handle 21 located outside the internal threaded tube 15. The cleaning component 6 is located outside the drum 3. The rotating roller 22 on the cleaning component 6 and the lower limiting ring 25 are both located inside the outer casing 2. The rotating shaft 24 passes upward through the first guide rail groove 10 and the shaft hole 17. The upper limiting ring 25 is rotatably installed in the annular anti-detachment groove 18. During the centrifugal washing of the hydrotalcite, some hydrotalcite and washed impurities will clog the mesh of the drum 3. Thus, the gaps between the centrifugal washing of the hydrotalcite can be used to clean the clogged mesh of the drum 3. At this time, the drive device 9 is maintained. The operation keeps the drum 3 rotating. Then, the operator turns the handle 21 on the adjusting component 5. The handle 21 drives the lead screw 20 to rotate inside the internal thread tube 15. During the rotation of the lead screw 20, it pushes the moving plate 16 to slide inside the rectangular frame 11. The limiting blocks 19, which are symmetrically fixed at the left and right ends of the moving plate 16, slide synchronously along the second guide rail grooves 13 opened on the left and right side walls of the rectangular frame 11. When the moving plate 16 slides, it drives the rotating shaft 24 of the cleaning component 6 to move along the first guide rail groove 10 opened on the upper side wall of the outer shell 2 until the hard bristles 23 on the cleaning component 6 are tightly attached to the outer wall of the drum 3. At this time, the friction generated by the rotation of the drum 3 causes the cleaning component 6 to rotate on the moving plate 16. During the rotation, the stiff bristles 23 insert into the mesh of the side wall of the drum 3 to remove the small particles and impurities of the hydrotalcite embedded in the mesh. The removed impurities can be discharged through the water outlet pipe 8 with the cleaning water introduced during the subsequent washing of the hydrotalcite. After cleaning, the handle 21 is turned in the opposite direction, which drives the lead screw 20 to rotate in the opposite direction, causing the moving plate 16 and the cleaning component 6 to move away from the drum 3, thereby causing the stiff bristles 23 of the cleaning component 6 to separate from the drum 3, completing the mesh cleaning of the drum 3 in preparation for the next centrifugal washing operation.
[0017] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
