Description

Technical Field

[0001] This utility model belongs to the field of recycling equipment technology, specifically relating to an aluminum fluoride purification and recycling equipment. Background Technology

[0002] Aluminum fluoride has a wide range of industrial applications, such as as a catalyst, intermediate, or raw material in the production of other chemicals. However, it is important to note that aluminum fluoride is a toxic substance and can be harmful to health if inhaled or comes into contact with the skin. Appropriate safety measures should be taken when handling aluminum fluoride. During the production of aluminum fluoride, when using the wet process, the crude aluminum fluoride produced by the reaction has a reaction solution adhering to its surface. After drying, this will affect the purity of the aluminum fluoride. Therefore, the crude aluminum fluoride needs to be cleaned and purified.

[0003] The usual method of using cleaning equipment is to place crude aluminum fluoride into a cleaning tank and then agitate it for cleaning. However, after cleaning, the fine aluminum fluoride particles are difficult to recover, which not only causes the loss of aluminum fluoride but also affects the overall production efficiency of aluminum fluoride.

It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0020] like Figure 1 and 4 As shown, an aluminum fluoride purification and recovery device includes a cleaning tank 1 and a holding assembly 2. The holding assembly 2 is detachably connected to the inside of the cleaning tank 1. The side wall of the cleaning tank 1 is provided with a rinsing structure 3. The holding assembly 2 includes a material container 21. An arc-shaped hopper 24 is provided at the bottom of the material container 21. A second L-shaped connecting plate 25 is fixedly connected between the material container 21 and the arc-shaped hopper 24 and is equidistantly distributed around the axis of the material container 21. The surface of the material container 21 and the surface of the arc-shaped hopper 24 are provided with uniformly distributed through holes 27. A filter screen 28 is provided inside the arc-shaped hopper 24.

[0021] According to the above structure, when rinsing aluminum fluoride, aluminum fluoride is placed inside the holding tank 21, cleaning water is injected into the cleaning tank 1, and then the water is circulated through the rinsing structure 3 to rinse the aluminum fluoride inside the holding tank 21. The through holes 27 provided on the surface of the holding tank 21 facilitate the flow of water inside and outside the holding tank 21, thereby improving the rinsing and purification effect. Fine aluminum fluoride particles are flushed out from inside the holding tank 21 through the through holes 27 during rinsing and fall into the inside of the filter screen 28. During subsequent recycling, they can be directly taken out from inside the cleaning tank 1 to facilitate the recovery of alumina.

[0022] like Figure 2 and 3 As shown, the cleaning tank 1 includes an inner tank 11 and an outer tank 12. The outer tank 12 is fixedly connected inside the inner tank 11. A third partition 16, a second partition 14, and a first partition 13 are fixedly connected between the inner tank 11 and the outer tank 12 from top to bottom. The water inlet chamber 17 is between the third partition 16 and the top of the outer tank 12. The water outlet chamber 15 is between the first partition 13 and the second partition 14. The inner wall of the water inlet chamber 17 is provided with equidistantly distributed water inlet holes 19. The inner wall of the water outlet chamber 15 is provided with equidistantly distributed water outlet holes 18. The flushing structure 3 includes a water pump 31 fixedly connected to the outer wall of the inner tank 11. The water inlet and outlet of the water pump 31 are both fixedly connected to connecting pipes 32. One end of each connecting pipe 32 is fixedly connected to the water outlet chamber 15 and the water inlet chamber 17, respectively.

[0023] According to the above structure, when rinsing alumina, the water pump 31 is started to extract the water inside the water chamber 15 and then pump it into the water inlet chamber 17. The water flows back to the top of the outer tank 12 through the water inlet hole 19, and the water at the bottom of the outer tank 12 flows into the water outlet chamber 15 through the water inlet hole 19, thereby realizing the circulation of water, which facilitates the rinsing and purification of the aluminum fluoride inside the material container 21.

[0024] like Figure 3 and 4 As shown, a ring 22 is provided above the material container 21. The bottom end of the ring 22 is in contact with the top end of the outer tank 12. A uniformly distributed first L-shaped connecting plate 23 is fixedly connected between the bottom end of the ring 22 and the top end of the material container 21. An equally spaced reinforcing plate 26 is fixedly connected to the top end of the arc-shaped hopper 24.

[0025] According to the above structure, the entire container assembly 2 is mounted inside the outer tank 12 by the ring 22. After rinsing, the ring 22 is pulled up to pull the entire container assembly 2 out from inside the outer tank 12, making it easy to remove the aluminum fluoride. The reinforcing plate 26 can improve the strength of the arc-shaped bucket 24 and prevent the arc-shaped bucket 24 from deforming.

[0026] like Figure 3 As shown, a drain pipe 4 is fixedly connected to the bottom end of the outer tank 12. The drain pipe 4 passes through the bottom end of the inner tank 11, and a valve 41 is installed on the drain pipe 4.

[0027] According to the above structure, after rinsing, valve 41 is opened to drain the water inside the outer tank 12.

[0028] The working principle of this utility model is as follows: When rinsing aluminum fluoride, aluminum fluoride is placed inside the holding tank 21, and cleaning water is injected into the cleaning tank 1. Then, the water is circulated through the rinsing structure 3 to rinse the aluminum fluoride inside the holding tank 21. The through holes 27 on the surface of the holding tank 21 facilitate the flow of water inside and outside the holding tank 21, thereby improving the rinsing and purification effect. Fine aluminum fluoride particles are flushed out from inside the holding tank 21 through the through holes 27 during rinsing and fall into the filter screen 28. During subsequent recycling, they can be directly removed from inside the cleaning tank 1 for easy recovery of alumina. When rinsing alumina, the water pump 31 is started to draw water from the water chamber 15. Water is pumped into the inlet chamber 17 and then flows back to the top of the outer tank 12 through the inlet hole 19. Water at the bottom of the outer tank 12 flows into the outlet chamber 15 through the inlet hole 19, thus realizing the circulation of water. This facilitates the rinsing and purification of the aluminum fluoride inside the container 21. The entire container assembly 2 is mounted inside the outer tank 12 by the ring 22. After rinsing, the ring 22 is pulled up to pull the entire container assembly 2 out of the outer tank 12, making it easy to remove the aluminum fluoride. The reinforcing plate 26 can improve the strength of the arc-shaped bucket 24 and prevent the arc-shaped bucket 24 from deforming. After rinsing, the valve 41 is opened to drain the water inside the outer tank 12.

[0029] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
