Description

Technical Field

[0001] The utility model relates to the technical field of electrolytic aluminum production, in particular to an electrolytic aluminum rotary feeder. Background Art

[0002] Electrolytic aluminum is a common industrial production method for producing high-purity aluminum metal. During production, aluminum oxide powder and auxiliary electrolyte need to be continuously added to the electrolytic cell, so a feeder is needed.

[0003] In application number 2017207251669, the patent name is automatic reset feeder. Two baffle valves are set in this patent. Through the action of the cylinder, when the baffle valve at the lower end is opened, the discharge port at the lower end of the steel cylinder is opened, and at the same time, the baffle valve at the upper end closes the feed port at the upper end of the steel cylinder. At this time, the fluoride salt in the steel cylinder is added to the electrolytic cell from the opened discharge port. When the cylinder contracts, the baffle valve at the lower end closes the discharge port, and the baffle valve at the upper end opens, so that the fluoride salt is added to the steel cylinder from the feed port at the upper end of the steel cylinder.

[0004] However, in the above patent, since the fluoride salt in the steel cylinder is added into the electrolytic cell straight up and down, the fluoride salt will be stacked in the electrolytic cell, resulting in the supplementary fluoride salt not being able to evenly cover the surface of the electrolytic cell. Utility Model Content

[0005] The main purpose of the utility model is to provide a rotary feeder for electrolytic aluminum, which solves the above-mentioned problems.

[0006] In order to achieve the above-mentioned purpose, the utility model provides an electrolytic aluminum rotary feeder, comprising a fixed plate, a rotating assembly, a lifting assembly and a cylinder;

[0008] The lifting assembly is inside the cylinder, and includes a lifting member, a driving cylinder, an upper closing plate and a lower closing plate. The upper closing plate and the lower closing plate are respectively arranged on the driving cylinder, the upper closing plate corresponds to the feed port, and the lower closing plate corresponds to the discharge port.

Fluoride salt is added into the cylinder through the opened feed port. After a certain amount is added, the driving cylinder is moved down, the upper closing plate closes the feed port, and the lower closing plate moves down to open the discharge port. At this time, the fluoride salt in the cylinder continuously falls onto the rotating disk through the discharge port and the feeding channel, and then the rotating shaft is driven to rotate by the driving member to rotate the rotating disk. Through the rotation of the rotating disk, the fluoride salt is thrown into the electrolytic cell, so that the fluoride salt is evenly covered in the electrolytic cell, thereby solving the problem of fluoride salt accumulation in the electrolytic cell.

[0011] A preferred solution is that the lifting member includes a lifting cylinder and a lifting frame, the lifting cylinder is arranged at the upper end of a fixed plate, the telescopic rod of the lifting cylinder passes through the fixed plate and is connected to the lifting frame, and the lower end of the lifting frame drives the upper outer wall of the cylinder to be connected.

[0018] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0019] like Figures 1 to 3 As shown, the utility model provides an electrolytic aluminum rotary feeder, comprising a fixed plate 10, a rotating assembly 20, a lifting assembly 30 and a cylinder 40;

[0020] The cylinder 40 is disposed below the fixed plate 40 , a feed port 41 is disposed at the upper end of the cylinder 40 , a discharge port 42 is disposed at the lower end of the cylinder 40 , and a discharge channel 43 is disposed at the lower end of the discharge port 42 ;

[0021] The lifting assembly 30 is in the cylinder 10, and the lifting assembly 30 includes a lifting member 310, a driving cylinder 31, an upper closing plate 32 and a lower closing plate 33. The upper closing plate 32 and the lower closing plate 33 are respectively arranged on the driving cylinder 31, the upper closing plate 32 corresponds to the feed port 41, and the lower closing plate 33 corresponds to the discharge port 42. The lifting member 310 is used to drive the driving cylinder 31 to rise or fall;

[0022] The rotating assembly 20 includes a driving member 210, a rotating shaft 21, a rotating disk 22 and a bending plate 23. The rotating shaft 21 is arranged through a driving cylinder 31. The driving member 210 is used to drive the rotating shaft 21 to rotate. The rotating disk 22 is arranged at the lower end of the rotating shaft 21, and a plurality of the bending plates 23 are arranged at the upper end of the rotating disk 22.

[0023] During the operation, the lifting member 310 drives the driving cylinder 31 to move up or down. When the driving cylinder 31 moves up, the upper sealing plate 32 moves up to open the feed port 41, and the lower sealing plate 33 closes the discharge port 42. Fluoride salt is added into the cylinder 40 through the opened feed port 41. After a certain amount is added, the driving cylinder 31 moves down, the upper sealing plate 32 closes the feed port 41, and the lower sealing plate 33 moves down to open the discharge port 42. At this time, the fluoride salt in the cylinder 40 continuously falls onto the rotating disk 22 through the discharge port 42 and the feeding channel 43. Then, the driving member 210 drives the rotating shaft 21 to rotate, so that the rotating disk 22 rotates. Through the rotation of the rotating disk 22, the fluoride salt is thrown into the electrolytic cell, so that the fluoride salt is evenly covered in the electrolytic cell, thereby solving the problem of fluoride salt accumulation in the electrolytic cell.

[0024] In addition, the fluoride salt dropped onto the rotating disk 22 is dispersed by the action of the curved plate 23 .

[0025] Preferably, the lifting member 310 includes a lifting cylinder 311 and a lifting frame 312. The lifting cylinder 311 is arranged at the upper end of the fixed plate 10. The telescopic rod of the lifting cylinder 311 passes through the fixed plate 10 and is connected to the lifting frame 312. The lower end of the lifting frame 312 is connected to the upper outer wall of the driving cylinder 31.

[0026] When the lifting cylinder 311 extends, the lifting frame 312 descends, and the lifting frame 312 drives the cylinder 31 to move downward, and the cylinder 31 moves downward along the rotating shaft 21, so that the upper closing plate 32 closes the feed port 41, and the lower closing plate 33 moves downward to open the discharge port 42. When the lifting cylinder 311 contracts, the cylinder 31 moves upward, so that the upper closing plate 32 moves upward, so that the feed port 41 is opened, and the lower closing plate 33 moves upward to close the discharge port 42. When the cylinder 31 moves upward or downward, it moves along the rotating shaft 22.

[0027] Preferably, the driving member 210 includes a U-shaped frame 211, a driving gear 212 and a driven gear 213, the upper end of the U-shaped frame 211 is connected to the fixed plate 10, the driven gear 213 is arranged on the rotating shaft 21, the driving gear 212 is meshed and connected with the driven gear 213, and the driving gear 212 is connected to the motor 214.

[0028] When the discharge port 42 is opened, the fluoride salt in the cylinder 40 continuously falls onto the rotating disk 23 through the discharge channel 43. At this time, the motor 214 drives the driving gear 212 to rotate, and the driven gear 213 drives the rotating shaft 21 to rotate, and the rotating shaft 21 drives the rotating disk 22 to rotate. As the rotating disk 22 rotates, the fluoride salt is evenly scattered into the electrolytic cell.
