Description

Technical Field

[0001] This utility model belongs to the field of stirred tanks, specifically, it relates to an aluminum hydroxide stirred tank. Background Technology

[0002] Aluminum hydroxide is an inorganic compound that can react with both acids and strong bases to form salts and water, making it an amphoteric hydroxide. Because it also exhibits some acidity, it can be called aluminic acid. However, when it actually reacts with a base, it forms tetrahydroxyaluminate, so it is usually considered as monohydrate aluminic acid. It is classified into industrial and pharmaceutical grades according to its applications. During the production of aluminum hydroxide, to ensure thorough mixing of particles of different sizes, prevent agglomeration, and guarantee uniform reaction, stirring is often required, necessitating a stirring tank for mixing.

[0003] Currently, when mixing aluminum hydroxide in a mixing vessel and transporting it to a storage device for further processing, the inner wall of the vessel needs to be cleaned to prevent residual material from adversely affecting the next mixing of aluminum hydroxide. However, existing cleaning equipment for the inside of the mixing vessel can only clean the inner wall by high-pressure spraying of clean water, which is insufficient to ensure that there is no material residue on the inner wall. In order to ensure that there is no material residue on the inner wall of the mixing vessel that could affect the next mixing, this utility model is proposed. Utility Model Content

Detailed Implementation

[0029] The present invention will now be described in further detail with reference to the accompanying drawings.

[0030] Please see Figures 1 to 5 This utility model provides a technical solution: an aluminum hydroxide stirring vessel, including a vessel body 1, a top cover 2, a main stirring rod 3 and a cleaning strip 12. The top cover 2 is installed at the upper end of the vessel body 1. The main stirring rod 3 and the auxiliary stirring rod 4 are rotatably connected in the middle of the top cover 2 through a sealed bearing. A first stirring rod 5 and a second stirring rod 6 are fixed on both sides of the main stirring rod 3 and the auxiliary stirring rod 4, respectively. The first stirring rod 5 has a liquid injection chamber that communicates with the internal cavity of the main stirring rod 3. A one-way high-pressure nozzle 7 is fixed at the end of the first stirring rod 5. A rotary joint 8 is installed at the top of the liquid injection chamber. The upper end of the rotary joint 8 is connected to a liquid injection pipe 9 for the cleaning liquid to enter.

[0031] The inner side of the vessel body 1 is symmetrically fixed with annular rails 11 for the rotation of the transmission rings 10. A cleaning strip 12 is fixed between two adjacent transmission rings 10. Each cleaning strip 12 has a groove on the opposite side of the inner wall of the vessel body 1 for the installation of a scraper 13 and a cleaning brush 14. The cleaning brush 14 and the scraper 13 are both made of corrosion-resistant material. The cleaning brush 14 and the scraper 13 are fixed by a limiting bolt 15 at the front end of the cleaning strip 12.

[0032] Each transmission ring 10 has a rolling element 16 on its outer side that contacts the inner side of the annular rail 11. The inner side of the transmission ring 10 has a snap tooth 18 that meshes with the first drive gear 17. The two first drive gears 17 are fixedly installed on the outside of the same drive rod 19. The bottom of the drive rod 19 is rotatably connected to the inside of the vessel body 1. The top of the drive rod 19 passes through the upper cover 2 and is fixed to the output shaft of the first motor 20 through a coupling.

[0033] A feed valve 21 is connected to the upper side of the vessel body 1 via a pipe, and a pressure gauge 22 is installed on the other side of the upper end of the vessel body 1. A discharge valve 23 is connected to the bottom of the vessel body 1. Considering that existing cleaning equipment for cleaning the inside of the mixing vessel can only clean the inner wall of the mixing vessel by simply spraying clean water under high pressure, it is difficult to ensure that there is no material residue on the inner wall of the mixing vessel. This utility model uses a first motor 20, a drive rod 19, and a transmission ring 10 to drive the cleaning strip 12 to rotate. When the cleaning strip 12 rotates, it will clean the inner surface of the vessel body 1 through the scraper and cleaning brush on its surface. It can also be used in conjunction with the one-way pressurized nozzle of the rotating first stirring rod 5 to spray cleaning liquid, thereby achieving a thorough cleaning of the inner wall of the vessel body 1.

[0034] The upper end of the cover 2 is symmetrically fixed with C-shaped blocks 24. The middle of the two C-shaped blocks 24 is rotatably connected to the transmission gears 25, and the outer sides of the two transmission gears 25 are meshed with driven gears 26. The two driven gears 26 are fixedly sleeved on the outer upper end of the two auxiliary stirring rods 4. The other side of the two transmission gears 25 is meshed with the same second drive gear 27, and the second drive gear 27 is fixedly sleeved on the outer top of the main stirring rod 3. By setting the transmission gears 25, driven gears 26 and drive gears for transmission, when the second motor 28 drives one of the driven gears 26 to rotate, multiple gears are connected by meshing to transmit power, thereby realizing the rotation of the main stirring and auxiliary stirring rods 4.

[0035] One of the auxiliary stirring rods 4 is fixed to the output shaft of the second motor 28 by a coupling. Both the second motor 28 and the first motor 20 are fixed to the top cover by a chassis and an L-shaped bracket. The chassis and L-shaped bracket are used to fix the first motor 20 and the second motor 28.

[0036] The bottoms of the main stirring rod 3 and the auxiliary stirring rod 4 are rotatably connected to the support 29 via bearings, and the support 29 is fixedly installed inside the vessel body 1. By setting the support 29 in conjunction with the bearings, the bottoms of the main stirring rod 3 and the auxiliary stirring rod 4 are supported, that is, without affecting the rotation of the main stirring rod 3 and the auxiliary stirring rod, the support is provided, thus improving the stability during rotation.

[0037] The first stirring rod 5 and the second stirring rod 6 are staggered, and the outer surfaces of the first stirring rod 5 and the second stirring rod are fixed with shearing protrusions 30. The contours of the shearing protrusions 30 of the first stirring rod 5 and the second stirring rod 6 are matched. Considering that material agglomeration is easy to occur during the stirring process, the above structure is designed to break up the agglomerates. That is, when the agglomerates are displaced to the staggered area of ​​the first stirring rod and the second stirring rod, the agglomerates will be crushed by the shearing protrusions 30 on the surface of the first stirring rod 5 and the second stirring rod 6.

[0038] The lower end of the injection pipe 9 is connected to the outlet end of the booster pump 31. The booster pump 31 is fixedly installed on the top of the storage tank 33 on the outside of the vessel body. The negative pressure end of the booster pump 31 passes through the negative pressure pipe 32 into the interior of the storage tank 33 and is fixed to the filter cover 34 by the pipe clamp. By setting the booster pump 31, the cleaning liquid in the storage tank 33 is boosted and pumped, so that it can work with the one-way booster nozzle to spray high pressure liquid to rinse the inner wall of the vessel body 1.

[0039] The storage tank 33 has a filter box 36 fixed inside by an L-shaped block 35. The filter box 36 has an outlet at the top. The inlet pipe of the filter box 36 passes through the side of the storage tank 33 and is connected to the inlet valve 37. The filter box 36 has clips 39 for installing filter plates 38 fixed at equal intervals inside. The front end of the filter box 36 is fixed with a sealing cover 40 by screws. The filter box 36 filters the cleaning fluid that enters through the inlet valve 37, avoiding the blockage of the pipeline caused by particulate matter in the cleaning fluid. That is, in the process of the liquid flowing from the inlet pipe of the filter box 36 through the outlet of the filter box 36, the particulate matter in the liquid will be filtered by multiple filter plates 38.
