Description

Technical Field

[0001] This utility model relates to the field of conveying mechanism technology, and in particular to an aluminum fluoride conveying mechanism. Background Technology

[0002] Aluminum fluoride is a colorless or white crystal and an important additive in the aluminum electrolysis production process. It can lower the melting point and viscosity of the electrolyte and improve its conductivity, thereby reducing energy consumption in the electrolysis process and improving the production efficiency and quality of aluminum. In the existing dry process of aluminum fluoride production, the aluminum fluoride produced by the fluidized bed reactor needs to be cooled down before storage.

[0003] An adjustable conveying pipe for aluminum fluoride, with authorized publication number CN217463252U, includes a bushing, an upper fixing clamp, and a conveying pipe body. The conveying pipe body is mounted on the bottom of the bushing, and a set of upper fixing clamps is mounted on the outer wall of the conveying pipe body. A transmission chamber is mounted on the top of the bushing, and a first through hole is formed on the outer wall of the transmission chamber. This invention utilizes an annular control valve, a valve stem, and a valve plate. Rotating the annular control valve drives a first gear to rotate, which in turn drives a second gear to rotate. The second gear then drives the valve stem, which in turn drives the valve plate and a sealing gasket to rotate. Through the arrangement of the valve plate and sealing gasket, the rotation of the valve plate allows for adjustment of the conveying flow rate of the conveying pipe body, thus improving the practicality of the conveying pipe body.

[0004] Regarding the aforementioned technologies, the existing conveying devices have the following drawbacks: after aluminum fluoride is generated, it is only cooled by air cooling, which has poor heat dissipation effect. When hot aluminum fluoride enters the storage equipment through the conveying device, it will cause uneven heating in some areas of the storage equipment, generating thermal stress. Over time, this will accelerate the aging and damage of the equipment and shorten its service life. Therefore, this utility model provides an aluminum fluoride conveying mechanism.

The first circulating cooling pump 6 forms a circulation loop for the condensate. The first return pipe 7 passes through the conveying cylinder 1 and is connected to the other end of the rotating pipe 3. Both the first delivery pipe 5 and the first return pipe 7 are rotatably connected to the inner wall of the rotating pipe 3. This rotatable connection ensures the delivery of condensate without hindering the rotation of the rotating pipe 3. Cooling holes 15 are provided on the inner side of the conveying cylinder 1. The cooling holes 15 are threaded, which increases the flow path and time of the condensate in the conveying cylinder 1, enabling more thorough cooling of the conveying cylinder 1 and the aluminum fluoride material inside. A second circulating cooling pump is fixedly connected to the outer side of the conveying cylinder 1. 11. The second circulating cooling pump 11 provides power for the circulation of condensate in the cooling hole 15, so that the condensate flows continuously in the cooling hole 15.

A gear ring 4 that meshes with the gear 10 is fixedly connected to the outer side of the rotating tube 3. Through the meshing transmission of gear 10 and gear ring 4, the power of motor 9 is transmitted to rotating tube 3, enabling rotating tube 3 to rotate inside conveying cylinder 1, thereby assisting in the conveying of materials inside conveying cylinder 1; a connected feed pipe 2 is fixedly connected to the outside of conveying cylinder 1, which is the inlet for materials to enter conveying cylinder 1, facilitating the input of materials; a connected output pipe 13 is fixedly connected to the outside of conveying cylinder 1, which is the channel for materials to be output from conveying cylinder 1; a solenoid valve 14 is installed on the outside of output pipe 13, which can control the opening and closing of output pipe 13, realizing precise control of material output.

[0024] The working principle of this utility model is as follows: Raw materials are introduced into the conveying cylinder 1 through the feed pipe 2. The motor 9 drives the gear 10 to rotate, which in turn drives the rotating pipe 3 and the auger blades 17 to rotate through the gear ring 4, thus conveying the raw materials. The first circulating cooling pump 6 is controlled to introduce condensate into the rotating pipe 3 and the auger blades 17 through the first liquid delivery pipe 5, thereby achieving internal cooling of the raw materials during the material conveying process. The condensate flows back to the first circulating cooling pump 6 through the first return pipe 7.
