Description

Technical Field

[0001] This utility model relates to the field of electrolytic aluminum production technology, and in particular to an alumina feeder. Background Technology

[0002] In the production of electrolytic aluminum, the anode residue (carbon block) needs to be crushed and mixed with alumina raw materials in a certain proportion. The main purpose is to recover the alumina component in the residue and reduce raw material waste.

[0003] The traditional method of blending crushed alumina residue with alumina raw materials is as follows: a conveyor belt is set up at the alumina residue cleaning station to transport the crushed alumina residue. A grid plate is set up above the alumina residue belt, and the alumina bag is placed on the grid plate. A hole is manually cut at the bottom of the alumina bag so that the alumina raw materials inside the alumina bag fall onto the alumina residue belt through the grid plate holes under the action of gravity. However, this method has some obvious drawbacks: manually cutting the alumina bales is difficult to control the force applied, resulting in inconsistent opening sizes and uneven mixing. Larger openings lead to faster alumina material discharge, and in cases where the opening is particularly large, a large amount of alumina material falls onto the residual electrode conveyor belt simultaneously, causing difficulties in its operation and potentially leading to an emergency motor shutdown or belt slippage. Smaller openings result in slower alumina material discharge, which, in cases where the alumina material has poor flowability, can easily cause flow interruptions, requiring manual assistance and increasing the workload for employees. Furthermore, the alumina bales are transported using overhead crane hooks, and the bales themselves are heavy, making control difficult. Personnel standing on the grating plate to cut the swaying bales are at risk of falling and sustaining injuries. Utility Model Content

[0004] The purpose of this invention is to provide an alumina feeder to solve the problems existing in the prior art, enabling uniform mixing while effectively reducing manual intervention and lowering the risk of personnel falling.

[0005] To achieve the above objectives, this utility model provides the following solution: This utility model provides an alumina feeder, including a fixed bracket and a bag breaker. The fixed bracket is used to place on a grid plate above the residual electrode belt. The bag breaker is fixed on the fixed bracket and gradually contracts from bottom to top. The top of the bag breaker is a pointed tip, which is used to puncture the alumina bag when it falls onto the pointed tip.

[0006] Preferably, the pack-breaking device has at least three side plates symmetrically distributed about the center line of the pack-breaking device, and the side plates gradually taper from bottom to top.

[0007] Preferably, the side plate is a right-angled triangular plate.

[0008] Preferably, the number of side plates is four.

[0009] Preferably, a feeding hopper is fixedly provided on the fixed bracket, and the bottom end of the bag breaker is fixedly provided in the feeding hopper.

[0010] Preferably, the top of the packing breaker protrudes upwards above the hopper.

[0011] Preferably, a support frame is fixedly provided inside the hopper, and the bottom end of the bag breaker is fixedly provided on the support frame.

[0012] Preferably, the centerline of the packing breaker coincides with the centerline of the hopper.

[0013] Preferably, the hopper has a straight cylindrical section and a conical section from top to bottom, and the conical section gradually tapers inward from top to bottom; a feeding pipe is fixedly provided at the bottom end of the conical section, the top end of the feeding pipe is connected to the internal space of the conical section, and the bottom end of the feeding pipe is used to extend downward to pass through the grid plate.

[0014] Preferably, the inner diameter of the straight cylindrical section is 1.5 meters, the height of the straight cylindrical section is 0.5 meters, the inner diameter of the top of the conical section is 1.5 meters, the height of the conical section is 0.75 meters, and the inner diameter of the feed pipe is 10 centimeters and the height is 20 centimeters.

[0015] The present invention achieves the following technical advantages over the prior art: The alumina feeder provided by this utility model supports a bale breaker by placing a fixed bracket on a grid plate above the residual electrode belt. The bale breaker is designed with a pointed top that gradually tapers upwards, allowing the alumina bale to be punctured when it falls onto the pointed top, replacing manual bale cutting. Because the bale breaker has a fixed structure and each alumina bale has a uniform weight, the punctures made by the pointed top when each bale falls onto the pointed top are consistent, thus achieving uniform blending, improving production efficiency, ensuring stable operation of the electrolytic cell, and effectively reducing manual intervention and the risk of personnel falling.

The fixed bracket 1 is used to place on the grid plate above the residual electrode belt. The bag breaker 2 is fixed on the fixed bracket 1. The bag breaker 2 gradually shrinks from bottom to top. The top of the bag breaker 2 is a pointed tip, which is used to puncture the alumina bag when it falls onto the pointed tip.

[0022] The alumina feeder provided by this utility model supports the bale breaker 2 by placing the fixed bracket 1 on the grid plate above the residual electrode belt. The bale breaker 2 is designed with a pointed top that gradually tapers from bottom to top, so that when the alumina bale falls onto the pointed top, the pointed top can puncture the alumina bale, replacing manual cutting. Since the structure of the bale breaker 2 is fixed and the weight of each alumina bale is consistent, the punctures made by the pointed top when each alumina bale falls onto the pointed top are consistent, thereby achieving uniform mixing, improving production efficiency, ensuring the stable operation of the electrolytic cell, and effectively reducing manual intervention and the risk of personnel falling.

[0023] During production, the alumina bale is lifted and released. As it falls, the alumina bale comes into contact with the bale breaker 2 and is pressed by gravity, thus being punctured by the bale breaker 2.

The bottom of the four right-angled triangular steel plates is welded to the support frame 5. The pack breaker 2 can puncture a square opening with a side length of 0.7 meters on the alumina pack.

[0031] In a preferred embodiment of this utility model, the center line of the packing breaker 2 coincides with the center line of the hopper 4, which facilitates manufacturing and use.

[0032] In a preferred embodiment of this utility model, the hopper 4 has a straight cylindrical part 6 and a conical part 7 arranged sequentially from top to bottom. The conical part 7 gradually tapers inward from top to bottom. A feeding pipe 8 is fixedly provided at the bottom end of the conical part 7. The top end of the feeding pipe 8 is connected to the internal space of the conical part 7. The bottom end of the feeding pipe 8 is used to extend downward to pass through the grid plate. After the alumina raw material enters the hopper 4, it flows along the inner wall of the conical part 7 into the feeding pipe 8, and then directly reaches the residual electrode belt below the grid plate through the feeding pipe 8. The feeding is stable and can avoid dust flying. Finally, the uniform mixing of alumina and crushed residual electrode is achieved, reducing the workload of workers.
