Description

Technical Field

[0001] This utility model relates to the field of crystalline aluminum chloride purification technology, specifically a purification device for crystalline aluminum chloride. Background Technology

[0002] Fly ash is a solid waste product from coal combustion. Its enormous quantity and long-term storage occupy vast amounts of land, causing serious environmental pollution. However, fly ash contains abundant valuable components such as alumina, giving it high resource recycling value. The traditional method of producing crystalline aluminum chloride from bauxite is facing challenges of rising costs and resource sustainability due to the increasing scarcity of bauxite resources. Therefore, developing a technology for producing crystalline aluminum chloride from fly ash can not only achieve resource utilization of fly ash and reduce environmental pollution, but also lower the production cost of crystalline aluminum chloride, resulting in significant economic and environmental benefits. Current crystalline aluminum chloride purification mainly involves soaking and rinsing with a reaction solution. The friction between soaking in the reaction solution is low, making it difficult to remove impurities from the surface of crystalline aluminum chloride in a single soaking process. Multiple soaking processes are required to maintain the quality of the crystalline aluminum chloride, resulting in a large demand for reaction solution and potential resource waste.

[0003] Based on this, a purification device for crystalline aluminum chloride is now provided, which can eliminate the drawbacks of existing devices. Summary of the Invention

The discharge port is connected to a receiving trolley. A quantitative feeding mechanism is provided inside the feed seat, and a countercurrent washing structure is provided at the output end of the stirring motor.

[0007] Based on the above technical solutions, this utility model also provides the following optional technical solutions:

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model uses a conveyor plate to move crystalline aluminum chloride towards the outlet, and a drive pump to move the reaction liquid towards the reflux seat. The crystalline aluminum chloride and the reaction liquid move in opposite directions. Countercurrent washing is used for crystalline aluminum chloride to improve the reaction effect, reduce the amount of reaction liquid used, and reduce the loss of aluminum chloride.

[0017] 2. This utility model uses several conveying plates to drive the crystalline aluminum chloride to move.

The rotating block 201 rotates to drive the feeding trough 202 to rotate. During the rotation of the feeding trough 202, a certain amount of crystalline aluminum chloride is transferred into the material seat 101. The feeding trough 202 then inputs a certain amount of crystalline aluminum chloride into the purification box 102 for purification.

[0030] In one embodiment, such as Figure 3 and Figure 4 As shown, the countercurrent washing structure includes a drive roller 301. One end of the drive roller 301 is fixedly connected to the output end of the stirring motor 103, and the other end of the drive roller 301 is rotatably connected to the inner wall of the purification tank 102. The surface of the drive roller 301 is fixedly connected to the conveying plate 302. The conveying plate 302 is uniformly provided with a plurality of first filter holes. The purification tank 102 is provided with an isolation element. The stirring motor 103 drives the drive roller 301 to rotate, and the drive roller 301 drives the plurality of conveying plates 302 to rotate. During the rotation, the conveying plates 302 carry the crystalline aluminum chloride being washed by the reaction liquid. The crystalline aluminum chloride is pushed by the conveying plates 302 towards the discharge port 104 and drains the reaction liquid through the first filter holes provided on the surface of the conveying plate 302.

[0031] In one embodiment, such as Figure 3 and Figure 4 As shown, the isolation element includes an interceptor seat 303. A plurality of interceptor seats 303 are uniformly arranged inside the purification chamber 102. A rotating seat 304 is provided in the middle of the interceptor seat 303. A plurality of second filter holes 305 are uniformly arranged on the surface of the interceptor seat 303. A rinsing unit is provided at the lower end of the purification chamber 102. A purification tank is formed by the plurality of interceptor seats 303 to isolate crystalline aluminum chloride. During the tumbling process, the crystalline aluminum chloride reacts repeatedly with the reaction liquid to increase the reaction efficiency. The second filter holes 305 provided on the surface of the interceptor seat 303 provide conditions for the flow of the reaction liquid.

[0032] In one embodiment, such as Figure 4 and Figure 5As shown, the rinsing unit includes a reflux seat 404, which is located at the lower end of the purification chamber 102. The side of the reflux seat 404 is connected to a circulation element, and the reaction liquid inside the purification chamber 102 is refluxed through the reflux seat 404 to provide conditions for the circulation of the reaction liquid.

[0033] In one embodiment, such as Figure 5 and Figure 6 As shown, the circulation element includes a collection tank 403. The surface of the collection tank 403 is provided with a regulating valve for replacing the reaction solution. A reflux seat 404 is connected to the side of the collection tank 403. The collection tank 403 is connected to one end of the infusion pipeline 402. The surface of the infusion pipeline 402 is provided with a drive pump. The other end of the infusion pipeline 402 is connected to the infusion seat 401. The reaction solution stored inside the collection tank 403 is output through the infusion seat 401. The reaction solution flows through several intercepting seats 303 and then flows back to the collection tank 403 through the reflux seat 404. The movement direction of the crystalline aluminum chloride is opposite to the flow direction of the reaction solution, realizing countercurrent washing of the crystalline aluminum chloride, accelerating the reaction speed, saving reaction solution, and reducing the loss of aluminum chloride. If hydrochloric acid is used as the reaction solution, after the reaction solution washes the aluminum chloride, the impurities increase. After a period of use, the reaction solution in the purification tank 102 can be gradually replaced by regulating valve.

[0034] The above embodiment discloses a purification device for crystalline aluminum chloride. Crystalline aluminum chloride is fed into a purification chamber 102 through a feed seat 101.

The rotation of the rotating block 201 drives the feeding trough 202 to rotate, quantitatively transferring the crystalline aluminum chloride from the feed seat 101 during the rotation of the feeding trough 202. The quantitative crystalline aluminum chloride is then fed into the purification chamber 102 for purification. A stirring motor 103 drives a transmission roller 301 to rotate, which in turn drives several feeding plates 302 to rotate. During the rotation of the feeding plates 302… The crystalline aluminum chloride, washed by the reaction liquid, is propelled by the conveyor plate 302 towards the outlet 104. The reaction liquid is drained through the first filter holes on the surface of the conveyor plate 302. A purification tank is formed by several interceptor seats 303 to isolate the crystalline aluminum chloride. During the tumbling process, the crystalline aluminum chloride reacts repeatedly with the reaction liquid, increasing reaction efficiency.

The reaction liquid is returned to the purification tank 102 through the return seat 404, providing conditions for circulating the reaction liquid. The reaction liquid stored in the collection tank 403 is output through the delivery seat 401. The reaction liquid flows through several interceptor seats 303 and returns to the collection tank 403 through the return seat 404. The movement direction of the crystalline aluminum chloride is opposite to the flow direction of the reaction liquid, achieving countercurrent washing of the crystalline aluminum chloride, accelerating the reaction speed, saving reaction liquid, and reducing aluminum chloride loss.
