Description

Technical Field

[0001] This utility model belongs to the field of alumina production, specifically, it relates to an aluminum hydroxide slurry decomposition device. Background Technology

[0002] Aluminum hydroxide is a hydroxide of aluminum. Because it exhibits a certain degree of acidity, it can also be called aluminum hydroxide monohydrate. It is classified into industrial grade and pharmaceutical grade according to its use. Aluminum hydroxide is a white, colloidal substance that is almost insoluble in water. It has a slow, long-lasting, and strong anti-acid effect, astringent properties, and mucosal protection, which can lead to constipation. It does not produce carbon dioxide, does not react with acids, and does not cause alkalosis. In the production process of aluminum hydroxide, a decomposition process is required for the aluminum hydroxide seed slurry.

[0003] Most existing aluminum hydroxide seed slurries are decomposed using stirring devices. However, some aluminum hydroxide seed slurries are quite large, and direct stirring affects the decomposition time and efficiency. Furthermore, existing decomposition stirring devices generally have poor stirring effects, long stirring times, and low stirring efficiency. Therefore, this utility model is proposed.

Detailed Implementation

[0027] The present invention will now be described in further detail with reference to the accompanying drawings.

[0028] Please see Figures 1 to 5This utility model provides a technical solution: an aluminum hydroxide slurry decomposition device, including a tank 1, an annular support 10, a grinding disc 11 and a crushing roller 5. The top of the tank 1 is fixed with a machine box 2. A groove for installing a first motor 3 is opened at the bottom of the machine box 2. The bottom of the machine box 2 is provided with two docking nozzles 4 that are inserted into the top of the tank 1. The inside of the machine box 2 is provided with two crushing chambers that communicate with the docking nozzles. Each crushing chamber is symmetrically provided with crushing rollers 5.

[0029] The inside of the casing 2 is fixed to the first motor 3 by the fixing block 6. The output shaft of the first motor 3 is fixed to the top of the stirring rod 8 inside the tank 1 by the coupling. The lower end of the stirring rod 8 is provided with a stirring rod 9. The upper end of the inside of the tank 1 is fixed with an annular support 10. A reserved hole for the stirring rod 8 is opened in the middle of the annular support 10. The upper end of the stirring rod 8 is provided with multiple grinding discs 11. Multiple grinding balls 12 are installed on the lower surface of each grinding disc 11. The grinding balls 12 are in contact with the surface of the annular support 10.

[0030] Both ends of the tank 1 are fixed with transparent covers 13 by screws. A discharge valve 14 is provided at the bottom of the tank 1. Considering that some aluminum hydroxide seed slurry pieces are relatively large, direct stirring will affect its decomposition time and efficiency. Moreover, the existing decomposition stirring devices generally have poor stirring effect, long stirring time, and poor stirring efficiency. This utility model uses the crushing roller 5 inside the crushing chamber and the annular support 10 and grinding balls 12 inside the tank 1, in conjunction with the grinding disc 11, to fully crush the larger pieces in the aluminum hydroxide seed slurry, thereby ensuring the subsequent stirring efficiency. That is, the smaller the pieces, the more conducive it is to subsequent stirring and decomposition. When the aluminum hydroxide seed slurry enters the crushing chamber, it will... Two grinding rollers 5 are used to initially crush the aluminum hydroxide seed slurry. The crushed agglomerated aluminum hydroxide seed slurry then enters the annular support 10. As it descends along the annular support 10 to the stirring area of ​​the tank 1, the rotating grinding disc 11 and the annular support 10 are used for auxiliary grinding to further reduce the particle size. When the rotating grinding disc 11 comes into contact with the annular support 10, the return spring 19 retracts and moves the grinding disc 11 upward inside the relief groove 18. That is, the rod of the fixing bolt 16 moves upward along the relief groove 18. As the stirring rod 8 rotates, the return spring 19 presses the grinding disc 11 down to the surface of the annular support 10, thus completing the re-adhesion with the surface of the annular support 10.

[0031] The grinding disc 11 has a positioning hole in the middle for the stirring rod 8 to pass through. A positioning sleeve 15 is fixed at the upper end of the positioning hole, and the positioning sleeve 15 is connected to the stirring rod 8 through a fixing bolt 16 and a nut 17. The stirring rod 8 has a relief groove 18 in the middle for the fixing bolt 16 to move up and down. A return spring 19 abuts against the opposite surface of the positioning sleeve 15 and the annular support 10, and the return spring 19 is sleeved on the outside of the stirring rod 8. Considering that the grinding disc 11 will cause friction between the grinding disc 11 and the annular support 10 when the grinding disc 11 rotates with the stirring rod 8, the positioning sleeve 15 is designed to prevent this. The surface of the ring support 10 comes into contact with the grinding disc 11. Therefore, in order to ensure that the movement of the grinding disc 11 is not obstructed, a relief groove 18 is designed to cooperate with the return spring 19 to ensure the rotation of the stirring rod 8. That is, when the grinding disc 11 comes into contact with the ring support 10, the grinding disc 11 is subjected to force, the return spring 19 pushes upward, and the rod of the fixing bolt 16 pushes upward along the relief groove 18, thereby causing the grinding disc 11 to move upward, thus making room for rotation. As the rotation returns to the point where the grinding disc 11 comes into contact with the surface of the ring support 10 again, the return spring 19 returns to its original position.

[0032] The lower end of the stirring rod 8 is fixed with a fixing sleeve 20 at equal intervals. The fixing sleeve 20 has a threaded groove for the installation of the stud 21. The stud 21 is fixedly installed on the end of the stirring rod 9. The stud 21 makes it convenient for the user to replace the stirring rod 9 later.

[0033] The first motor 3 is fixed to the groove by means of a fastener 22 and screws. A motor driver 23 connected to the first motor 3 is fixed at the front end of the fastener 22. The first motor 3 drives the stirring rod 8 to rotate.

[0034] In this configuration, the shafts of the two crushing rollers 5 inside each crushing chamber extend to the back of the housing 2 and are fixed to the sprocket 24. The two adjacent sprockets 24 are driven by a chain 25. The back of the housing 2 is fixed with a housing 26 for mounting the second motor 27. The output shaft of the second motor 27 passes through the housing 26 and is fixed to the shaft of one of the crushing rollers 5 via a coupling. The second motor 27, sprocket 24, and chain 25 drive the two crushing rollers 5.

[0035] The upper ends of the two crushing chambers are symmetrically fixed with guide plates 28. Each guide plate 28 has an elastic plate 29 in the middle. The opposite surfaces of the elastic plate 29 and the guide plate 28 are connected by a telescopic cover 30. The elastic plate 29 and the guide plate 28 are connected by a spring 31. Vibration motors 32 are symmetrically fixed at the lower ends of the guide plates 28. The guide plates 28 facilitate the entry of materials into the crushing area between the two crushing rollers 5. In order to help the materials to be fed, the vibration motors 32 will vibrate to drive the elastic plates 29 to vibrate.

[0036] The upper two sides of the casing 2 are fixed with support bases 33. Each support base 33 is hinged with a dust cover 34 through a shaft. Each dust cover 34 has an adsorption block 35 fixed on the contact surface with the middle of the casing 2. The adsorption block 35 is equipped with a magnetic block 7 that is magnetically attracted to the middle of the casing 2. The dust cover 34 also serves to prevent dust from entering the crushing chamber of the device when it is not in use.

Anyone should know that structural changes made under the guidance of this utility model, and any technical solutions that are the same as or similar to this utility model, fall within the protection scope of this utility model. Technical aspects, shapes, and structures not described in detail in this utility model are all publicly known technologies.
