Description

Technical Field

[0001] This utility model relates to the technical field of electrolytic aluminum processing equipment, and in particular to a chain hammer cleaning mechanism for electrolyte cleaning. Background Technology

[0002] In the electrolytic aluminum smelting process, a carbon anode connected to the anode rod assembly is typically immersed in an electrolytic cell containing molten electrolyte. Under the influence of the electric field between the carbon anode and the cathode at the bottom of the electrolytic cell, the carbon elements in the carbon anode react with the molten alumina in the electrolyte to generate carbon dioxide, reducing the aluminum ions in the alumina to elemental aluminum, thus completing the preparation of primary aluminum. During this electrolysis process, the carbon anode is continuously consumed, becoming a residual electrode after about 30 days. When the residual electrode returns from the electrolytic cell, the electrolyte covering its surface cools and solidifies, adhering to the surface of the residual electrode and around the steel claws, forming an electrolyte hard shell. This affects the recycling of the residual electrode, therefore, it is necessary to clean the electrolyte from the surface of the residual electrode.

[0003] Current electrolyte cleaning equipment typically includes a chain hammer cleaning mechanism, which uses a high-speed rotating chain to strike and dislodge the electrolyte. For example, patent document CN217774914U discloses a chain-spinning cleaning station and a dual-anode electrolyte cleaning system. This system uses a first and second chain-spinning component to perform a first and second chain-spinning cleaning operation on the dual-anode residual electrode assembly, respectively, to deeply clean the solidified electrolyte on the assembly after the scraping cleaning operation. However, in existing cleaning mechanisms, the installation position of the chain hammer is fixed, thus the cleaning position of the residual electrolyte is also essentially fixed. After automatic electrolyte cleaning, the electrolyte at the bottom of the carbon block often cannot be cleaned due to limitations in the equipment components. Utility Model Content

[0004] The purpose of this invention is to provide a chain hammer cleaning mechanism for electrolyte cleaning in order to solve the above-mentioned problems.

[0012] The beneficial effects are as follows: A second chain hammer mechanism is set at the feed point of the dustproof box. The second chain hammer mechanism includes a horizontal roller chain hammer. When the residual electrode passes over the horizontal roller chain hammer, the horizontal roller chain hammer can clean the electrolyte at the bottom of the residual electrode.

[0024] The present invention will be further described below with reference to the accompanying drawings:

[0025] like Figures 1-6 As shown, a chain hammer cleaning mechanism for electrolyte cleaning includes a dustproof box 1. The top of the dustproof box 1 has a slot 101 for a steel fork to pass through, and the front and rear sides of the dustproof box 1 have openings 102 for the passage of residual electrodes. Multiple first chain hammer mechanisms 2 are arranged inside the dustproof box 1 in a front-rear direction, evenly distributed on both sides of the slot 101. A second chain hammer mechanism 3 is arranged at the front end inside the dustproof box 1. The second chain hammer mechanism 3 includes two symmetrically arranged mounting seats 301, and a horizontal roller chain hammer 302 is rotatably mounted between the two mounting seats 301. The axis of the horizontal roller chain hammer 302 is horizontally arranged. When the residual electrode... When the electrode passes over the top of the horizontal roller chain hammer 302, the horizontal roller chain hammer 302 cleans the electrolyte residue at the bottom of the electrode. A second motor 303 is installed in a mounting base 301. The output end of the second motor 303 is fixedly connected to the horizontal roller chain hammer 302. The second motor 303 is used to drive the horizontal roller chain hammer 302 to rotate at high speed. The second chain hammer mechanism 3 also includes a lifting component for driving the mounting base 301 to move up and down. The height of the horizontal roller chain hammer 302 is adjusted by the lifting component to accommodate electrodes of different thicknesses. An air blowing mechanism 4 is provided at the rear end of the dustproof box 1. A safety door opening and closing mechanism 5 is provided on the rear side of the dustproof box 1.

[0026] The lifting assembly includes a first hydraulic cylinder 304, which is bolted to the bottom of the second chain hammer mechanism 3. A lifting seat 305 is fixedly connected to the top of the output shaft of the first hydraulic cylinder 304, and two mounting seats 301 are fixedly connected to the top of the lifting seat 305. The extension or retraction of the first hydraulic cylinder 304 will drive the lifting seat 305 to move up and down, so that the lifting seat 305 drives the mounting seats 301 and the horizontal roller chain hammer 302 to move up and down, thereby adjusting the height of the horizontal roller chain hammer 302.

[0027] The first chain hammer mechanism 2 includes a first motor 201, which is bolted to the top of the dustproof box 1. The output end of the first motor 201 is fixedly connected to a drive shaft 202, and the bottom end of the drive shaft 202 is fixedly connected to a vertical roller chain hammer 203. The vertical roller chain hammer 203 is located inside the dustproof box 1 and is symmetrically distributed on the left and right. When the residual electrode passes between the vertical roller chain hammers 203 on both sides, the high-speed rotating vertical roller chain hammers 203 clean the electrolyte residue on the other surfaces of the residual electrode.

[0028] The air blowing mechanism 4 includes two symmetrically arranged vertical plates 401, which are fixedly connected inside the dustproof box 1. An air pump 402 is bolted to the opposite sides of the two vertical plates 401. The air outlet of the air pump 402 is connected to an air supply pipe 403. The air pump 402 delivers compressed air into the air supply pipe 403. Multiple air blowing pipes 404 are connected to the air supply pipe 403. The air outlet of the air blowing pipe 404 faces the middle of the two vertical plates 401. By setting multiple air blowing pipes 404, small pieces and powdered electrolytes remaining on the residual electrode can be blown away.

[0029] The safety door opening and closing mechanism 5 includes safety doors 501 symmetrically arranged on both sides. The safety doors 501 prevent the electrolyte that has been cleaned from flying out from the opening 102 at the rear end of the dustproof box 1. The safety doors 501 are hinged to the rear side of the dustproof box 1. A fixed seat 502 is fixedly connected to the rear side of the dustproof box 1. A second hydraulic cylinder 503 is hinged to the fixed seat 502. The output end of the second hydraulic cylinder 503 is hinged to the safety door 501. The safety door opening and closing mechanism 5 also includes a guide rail 504, which is fixedly connected to the rear side of the dustproof box 1. The guide rail 504 is arc-shaped. The safety door 501 slides with the guide rail 504. The guide rail 504 provides a certain degree of support and guidance for the safety door 501, making the rotation of the safety door 501 more stable.

[0030] Working principle: During use, the residual electrode enters the dustproof housing 1 through the front opening 102. The second motor 303 drives the horizontal roller chain hammer 302 to rotate at high speed. The residual electrode passes over the top of the horizontal roller chain hammer 302. The high-speed rotating horizontal roller chain hammer 302 cleans the electrolyte residue at the bottom of the residual electrode. The first hydraulic cylinder 304 drives the lifting seat 305 to rise and fall. The lifting seat 305 drives the mounting seat 301 to rise and fall, and the mounting seat 301 drives the horizontal roller chain hammer 302 to rise and fall, thereby adjusting the height of the horizontal roller chain hammer 302 to accommodate residual electrodes of different thicknesses. After being cleaned by the horizontal roller chain hammer 302, the residual electrode continues to be conveyed backward. The residual electrode passes between the vertical roller chain hammers 203 on both sides. The first motor 201 drives the vertical roller chain hammers 203 to rotate at high speed. The vertical roller chain hammers 203 clean the electrolyte residue on other sides of the residual electrode, thereby achieving a comprehensive cleaning of the residual electrode. Then the residual electrode continues to be conveyed to the space between the two vertical plates 401. The air pump 402 delivers compressed air into the air delivery pipe 403. The compressed air is sprayed out through multiple air blowing pipes 404 to blow away the small pieces and powdery electrolyte on the residual electrode. After that, the second hydraulic cylinder 503 retracts and drives the safety door 501 to rotate and open, sending the cleaned residual electrode out from the rear opening 102, completing the cleaning work.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
