Description

Technical Field

[0001] This utility model relates to the technical field of aluminum electrolysis production equipment, and more specifically, to an automatic feeding device for an aluminum electrolysis overhead crane. Background Technology

[0002] Aluminum electrolysis is the process of obtaining aluminum through electrolysis. Modern industrial aluminum electrolysis production uses the cryolite-alumina molten salt electrolysis method. Molten cryolite is used as the solvent, alumina as the solute, carbonaceous material as the anode, and molten aluminum as the cathode. After a strong direct current is applied, an electrochemical reaction, or electrolysis, occurs at the two electrodes in the electrolytic cell at 950℃-970℃. During the production of electrolytic aluminum, it is necessary to feed materials into the electrolytic cell, and this process can be accomplished by an overhead crane.

[0003] In existing technologies, bucket elevators typically transport materials to a silo for storage. When anode material is needed, electrolysis personnel operate an overhead crane to the silo's discharge port, then operate the control box to open the silo's discharge valve and add the material into the crane's hopper. Finally, the crane pumps the material into the electrolytic cell's anode. However, the overhead crane's feeding device has poor flowability when there is a large amount of powder, leading to blockages and preventing material from being discharged. This requires manual intervention to clear the blockage, resulting in high labor intensity, high risk, and low work efficiency, hindering the anode sealing process in the electrolysis workshop. Furthermore, because the raw materials are added only once, they tend to accumulate in the electrolytic cell, failing to disperse evenly and affecting the electrolyte level. Utility Model Content

[0004] The purpose of this invention is to provide an automatic feeding device for an aluminum electrolysis overhead crane, which can prevent material blockage and allow the material to be evenly dispersed in the electrolysis cell, thereby improving the feeding speed and electrolyte quantity.

[0005] This utility model is achieved through the following technical solution:

[0006] An automatic feeding device for an aluminum electrolysis overhead crane includes a mounting frame on which a storage bin and a discharge bin are mounted. The discharge bin is located below the storage bin. A discharge pipe is provided between the storage bin and the discharge bin. A solenoid valve is provided at the inlet of the discharge pipe. A discharge mechanism is provided at the outlet of the storage bin. A plurality of evenly distributed discharge holes are provided at the bottom of the discharge bin. A rotary opening and closing mechanism is provided at the bottom of each discharge hole.

[0007] Furthermore, the feeding mechanism includes a rotating rod, on which a first stirring plate and a second stirring plate are mounted, and one end of the rotating rod extends out of the storage bin and is connected to a first motor.

[0008] Furthermore, the first and second stirring plates are fixed in a cross-shaped structure.

[0009] Furthermore, the rotating opening and closing mechanism includes a rotating plate, which is connected to the feeding hopper via a rotating shaft. A second motor is connected to the bottom end of the rotating shaft. Multiple connecting plates are evenly distributed around the outer periphery of the rotating plate. A baffle is provided at the end of the connecting plate away from the rotating plate, and the baffle is used to open and close the feeding hole.

[0010] Furthermore, a material deflector is provided inside the material discharge hopper, and the material deflector is fixedly connected to the rotating shaft.

[0011] Furthermore, the material slurry component includes a rotating column, which is fixedly connected to the rotating shaft, and a plurality of material slurries are provided on the rotating column.

[0012] Furthermore, a vibration motor is installed on the outside of the feeding pipe.

[0013] Furthermore, an electromagnetic flow meter is installed at the connection between the feeding pipe and the discharge bucket.

[0014] The technical solution of this utility model has at least the following advantages and beneficial effects:

[0015] This invention utilizes a storage tank, a feeding mechanism, a feeding pipe, and a discharge tank in conjunction. The feeding mechanism clears the material at the outlet of the storage tank, allowing it to flow through the feeding pipe into the discharge tank. This prevents material blockage during feeding, eliminates the need for manual clearing, and increases feeding speed. A solenoid valve controls the opening and closing of the feeding pipe, thereby controlling the amount of material entering the discharge tank and facilitating adjustments to the amount of material added to the electrolytic cell. The feeding hole and rotating opening / closing mechanism work together to allow material in the discharge tank to enter the electrolytic cell through the feeding hole, simultaneously achieving uniform dispersion of the material within the electrolytic cell and increasing electrolyte levels.

[0028] The feeding mechanism clears the material at the outlet of the storage tank 2, allowing it to enter the discharge tank 3 through the feeding pipe 4, thus preventing material blockage during the feeding process, eliminating the need for manual clearing, and increasing the feeding speed. The solenoid valve controls the opening and closing of the feeding pipe 4, thereby controlling the amount of material entering the discharge tank 3, facilitating adjustments to the amount of material added to the electrolytic cell. The rotating opening and closing mechanism allows the material in the discharge tank 3 to enter the electrolytic cell through the feeding hole 9, simultaneously achieving uniform dispersion of the material within the electrolytic cell and increasing the electrolyte content.

[0029] In this embodiment, the feeding mechanism includes a rotating rod 5, on which a first stirring plate 6 and a second stirring plate 7 are mounted. One end of the rotating rod 5 extends out of the storage tank 2 and is connected to a first motor 8.

[0030] In this embodiment, the first stirring plate 6 and the second stirring plate 7 are fixed in a cross structure. The cross structure can accelerate the material flow of the first stirring plate 6 and the second stirring plate 7, further improving the material feeding efficiency.
