Description

Technical Field

[0001] This invention belongs to the field of wet zinc smelting technology, and in particular relates to a mud removal structure for anode mud in an electrolytic cell. Background Technology

[0002] Anode slime is a sludge-like substance that adheres to the surface of the anode substrate, settles at the bottom of the electrolytic cell, or is suspended in the electrolyte during electrolytic refining. Its components are primarily metals, sulfides, selenium-tellurium compounds, oxides, elemental sulfur, and basic salts. Anode slime is enriched with most or all of the precious metals and certain rare elements from ores, concentrates, or fluxes, thus possessing high comprehensive recovery value.

[0003] In electrolysis, the accumulation of anode sludge can affect product purity. To ensure the normal operation of the electrolysis process, it is generally necessary to periodically brush off the adhering anode sludge, remove the settled anode sludge from the bottom of the tank, and filter the electrolyte to separate the suspended anode sludge. Currently, most solutions involve manually pumping it from the center of the electrode, which is highly dangerous and inefficient.

[0004] A search revealed that publication number CN205223379U, published on May 11, 2016, discloses a sludge removal structure for anode mud in an electrolytic cell. The structure includes: an electrolytic cell body, electrode plates, a motor, and a pneumatic diaphragm pump. The electrode plates are mounted on the electrolytic cell body. The motor is equipped with a winding shaft. A longitudinally sliding scraper is located at the bottom of the electrolytic cell. Pulleys are located at the upper and lower ends of both ends of the electrolytic cell. Two pull wires are located on both sides of the scraper, passing through the pullleys at the bottom and upper ends of the electrolytic cell respectively, and connecting to the winding shaft of the motor. The pneumatic diaphragm pump has a sludge extraction pipe and a sludge conveying pipe, with the other end of the extraction pipe located at both ends of the bottom of the electrolytic cell. By using the reciprocating sliding mechanism of the scraper at the bottom of the electrolytic cell and the pneumatic diaphragm pumps at both ends of the electrolytic cell, the anode mud at the bottom of the electrolytic cell can be extracted more efficiently, while also reducing the operational hazards.

[0005] This patent has the following shortcomings: 1. This sludge removal structure can only clean the sludge at the bottom of the electrolytic cell, and it is difficult to clean the surface of the anode substrate and the sides of the electrolytic cell. The effect of sludge removal and cleaning of the electrolytic cell is not ideal. 2. The sludge extraction location of this sludge extraction structure is fixed, making it difficult to achieve mobile sludge extraction, thus making it difficult to completely remove the sludge from the electrolytic cell.

[0006] Therefore, the existing anode mud extraction structure cannot meet the needs of actual use, so there is an urgent need for improved technology to solve the above problems. Summary of the Invention

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0025] Please see Figure 1 , 3 As shown, the present invention is a mud removal structure for anode mud in an electrolytic cell, including a scraping and mud removal assembly 1. The scraping and mud removal assembly 1 includes a mounting plate 11 and a scraper 12 and a mud removal main pipe 13 disposed at the bottom of the mounting plate 11. The scraper 12 and the mud removal main pipe 13 are arranged in parallel and have similar lengths. The bottom of the mud removal main pipe 13 is provided with a plurality of mud removal branch pipes 15 distributed at equal intervals. The mud removal main pipe 13 is fixed to the bottom of the mounting plate 11 by a pipe clamp 14. The end of the mud removal main pipe 13 is provided with a pipe joint 16, which is connected to an external pipe.

[0026] Among them, such as Figure 1 , 4As shown, the anti-clogging mechanism 2 is located at the bottom of the mounting plate 11 and is used to unclog the sludge pumping branch pipe 15. The anti-clogging mechanism 2 includes a J-shaped rod 21, an L-shaped fixing plate 22, a stop plate 23, a spring 24, a cam 25, a first motor 26, and a fixing platform 27. Multiple J-shaped rods 21 are provided, and each J-shaped rod 21 corresponds to one of the multiple sludge pumping branch pipes 15. The diameter of the J-shaped rod 21 is set to half the inner diameter of the sludge pumping branch pipe 15. The bottom end of the J-shaped rod 21... Inserted into the mud-dredging branch pipe 15, the top end of the J-shaped rod 21 moves through the L-shaped fixing plate 22. The top ends of multiple J-shaped rods 21 are fixed together with a stop plate 23. The stop plate 23 abuts against the cam 25. The cam 25 is fixedly sleeved on the output shaft of the first motor 26. The first motor 26 is fixed on the fixing platform 27. The L-shaped fixing plate 22 and the fixing platform 27 are both fixed to the bottom of the mounting plate 11. The spring 24 is sleeved on the J-shaped rod 21 between the stop plate 23 and the L-shaped fixing plate 22.

[0027] When the anti-clogging mechanism 2 is in use, the first motor 26 drives the cam 25 to rotate, the cam 25 drives the abutment 23 to move, and the abutment 23 drives multiple J-shaped rods 21 to move. Under the action of the spring 24, the abutment 23 always contacts the cam 25. As the cam 25 moves, the J-shaped rods 21 continuously insert or pull out of the mud pumping branch pipe 15, thereby effectively preventing the mud pumping branch pipe 15 from becoming clogged.

[0028] Among them, such as Figure 1 , 5 As shown, it also includes an angle adjustment mechanism 3, which includes a first adjustment component 31 and a second adjustment component 32 disposed on the top of the first adjustment component 31.

The first adjustment component 31 includes a first gear 311, a gear seat 312, a second gear 313, and a second motor 314. The lower end of the first gear 311 is fixedly connected to the top of the mounting plate 11. The first gear 311 is rotatably disposed in the gear seat 312, and the upper end of the first gear 311 meshes with the second gear 313. The second gear 313 is fixedly sleeved on the output shaft of the second motor 314, and the second motor 314 is fixed on the outer surface of the gear seat 312. The second adjustment component 32 includes a third gear 321, a fourth gear 322, and a third motor 323. The third gear 321 is horizontally fixed on the top of the gear seat 312, and the third gear 321 meshes with the fourth gear 322. The fourth gear 322 is fixedly sleeved on the output shaft of the third motor 323.

[0029] In specific use, the angle adjustment mechanism 3 is as follows: the second motor 314 drives the second gear 313 to rotate, the second gear 313 drives the first gear 311 to rotate, and the first gear 311 drives the mounting plate 11 to rotate, thereby adjusting the position of the scraper 12 and the mud-dredging main pipe 13; the third motor 323 drives the fourth gear 322 to rotate, the fourth gear 322 drives the third gear 321 to rotate, and the third gear 321 drives the first adjustment component 31 and the mounting plate 11 to rotate, thereby adjusting the position of the scraper 12 and the mud-dredging main pipe 13.

[0030] Among them, such as Figure 1 , 5 As shown, the lifting mechanism 4 is fixedly connected to the second adjusting component 32; the lifting mechanism 4 includes a lifting plate 41, a multi-section electric push rod 42, and a guide rod 43; the shaft of the third gear 321 is rotatably connected to the bottom of the lifting plate 41, and the third motor 323 is fixed to the top of the lifting plate 41; the lifting plate 41 is fixed to the movable end of the multi-section electric push rod 42, and the multi-section electric push rod 42 is fixed to the top of the moving block 51; four guide rods 43 are provided, which are fixed at the four corners of the top of the lifting plate 41, and their top ends can move through the moving block 51.

[0031] Among them, such as Figure 1 , 2 As shown in Figure 6, the planar moving mechanism 5 includes a moving block 51, a lifting mechanism 4 fixed on the moving block 51, and is located on the top of the support frame 6, which is fixed on the top of the electrolytic cell body 7. The planar moving mechanism 5 is used to drive the lifting mechanism 4 to move in the XY direction. The planar moving mechanism 5 also includes an X-axis moving rod 52 and a Y-axis moving rod 53, which are arranged at right angles and staggered vertically, and both of them move through the moving block 51. X-axis moving rods 54 are fixed at both ends of the X-axis moving rod 52 and are driven by an X-axis moving motor 55. Y-axis moving rods 56 are fixed at both ends of the Y-axis moving rod 53 and are driven by a Y-axis moving motor 57. A walking groove 61 is provided on the top of the support frame 6, and the X-axis moving wheel 54 and the Y-axis moving wheel 56 are both located in their respective walking grooves 61.

[0032] In practical use, the planar moving mechanism 5 drives the X-axis moving wheel 54 to rotate via the X-axis moving motor 55, so that the X-axis moving wheel 54 moves along the moving groove 61. The X-axis moving wheel 54 drives the moving block 51 to move along the Y-axis moving rod 53, and the moving block 51 drives the components on it to move. Similarly, the Y-axis moving wheel 56 is driven to rotate via the Y-axis moving motor 57, which can drive the moving block 51 to move along the X-axis moving rod 52.

[0033] The usage operation of this embodiment is as follows: S1: Based on the sludge scraping position, the orientation of the scraping and sludge extraction assembly 1 is adjusted by the angle adjustment mechanism 3. The sludge scraping position can be the four sides of the electrolytic cell body 7 and the bottom surface or the two sides of the anode plate. For example, when scraping the anode mud attached to the side of the electrolytic cell body 7, the scraping and sludge extraction assembly 1 is adjusted to a horizontal state by the first adjustment assembly 31, and the scraper 12 is placed above the sludge extraction main pipe 13. S2: The scraping and mud-removing assembly 1 is moved to the scraping position by the planar moving mechanism 5; S3: The lifting mechanism 4 drives the scraping and mud-drawing assembly 1 to descend, scrapes off the anode mud through the scraper 12, and extracts the scraped anode mud through the mud-drawing branch pipe 15. S4: During the sludge scraping process, the reciprocating motion of the anti-clogging mechanism 2 ensures that the sludge pumping branch pipe 15 is always in a clear state.

[0034] The above are merely preferred embodiments of the present invention and do not limit the present invention. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present invention.
