Description

Technical Field

[0001] This utility model relates to the field of electrolytic aluminum anode residue cleaning technology, specifically an electrolytic aluminum anode residue cleaning device. Background Technology

[0002] In the electrolytic aluminum industry, after use, the surface of the anode residue accumulates a large amount of electrolyte, dust, and other impurities. If these impurities are not cleaned in time, they will not only affect the recycling efficiency of the residue but may also have adverse effects on subsequent production processes.

[0003] In the electrolytic aluminum process, in the design of electrolytic cells using dual anodes, the covering material on the surface of the carbon blocks needs to be cleaned after use. Currently, the industry uses crushing trucks and manual cleaning, manual crushing and shot blasting, and automated cleaning processes using impactors. The latter has higher investment costs, while the former requires manual cleaning of the material blocks on the carbon blocks and blowing away the remaining powder, which increases the intensity of manual labor. Blowing away the powder also affects the health of workers. The high intensity of manual labor in intermediate processes also requires the use of overhead conveyors. Utility Model Content

[0004] The purpose of this invention is to provide an electrolytic aluminum anode residue cleaning device to solve the problems mentioned in the background art.

A first hinge frame is symmetrically fixedly connected to the bottom of the L-plate. A hydraulic rod is hinged to the two first hinge frames. Bearings are symmetrically arranged on the left side of the front and rear sides of the U-shaped frame. A rotating shaft is fixedly connected to the inner ring of the bearing. A residual electrode plate is fixedly connected to the surface of the rotating shaft.

[0012] Compared with the prior art, this utility model provides an electrolytic aluminum anode residue cleaning device, which has the following beneficial effects: 1. In this electrolytic aluminum anode residue cleaning device, the hydraulic rod is hinged between the first and second hinge frames in the tilting mechanism. By extending and retracting the hydraulic rod, the residue plate can be driven to rotate around the pivot to achieve the tilting action. This design allows for flexible adjustment of the tilt angle of the residue plate. The residue plate, after being crushed by the crusher, is hoisted onto the residue plate. After tilting, the material blocks and powder on the residue plate fall onto the conveyor belt due to gravity and are transported away.

[0013] 2. In this electrolytic aluminum anode residual electrode cleaning device, the high-pressure gas generated by the high-pressure air pump is transmitted to the air blowing hood via a first high-pressure air pipe, a telescopic air pipe, and a second high-pressure air pipe, enabling precise cleaning of the residual electrode surface. The telescopic air pipe can adapt to positional changes during the tilting of the residual electrode plate, ensuring the continuity and stability of the air blowing process. The air blowing hood can concentrate the high-pressure gas on a specific area according to the shape of the residual electrode and cleaning requirements, quickly and effectively removing dust from the residual electrode surface.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0018] This utility model provides the following technical solution: Example 1 Please see Figure 1-4 This utility model provides a technical solution: an electrolytic aluminum anode residue cleaning device, including a U-shaped frame 1, with support legs 2 symmetrically fixedly connected to the bottom of the U-shaped frame 1 in the front, back, left and right directions, an inclined mechanism 3 is provided at the bottom of the U-shaped frame 1, and a dust blowing mechanism 4 is provided on the right side of the inclined mechanism 3; The tilting mechanism 3 includes an L-plate 31, which is fixedly connected to the bottom right side of the U-shaped frame 1. The bottom of the L-plate 31 is symmetrically connected to a first hinge frame 32. A hydraulic rod 33 is hinged in the two first hinge frames 32. A bearing 35 is symmetrically arranged on the left side of the front and rear sides of the U-shaped frame 1. A rotating shaft 36 is fixedly connected to the inner ring of the bearing 35. A residual electrode plate 37 is fixedly connected to the surface of the rotating shaft 36. A second hinge frame 34 is symmetrically fixedly connected to the bottom front and rear sides of the residual electrode plate 37 near the right side.

[0019] The inner wall of the U-shaped frame 1 has holes on the front and rear sides near the left side that match the outer ring of the bearing 35, and the outer ring of the bearing 35 passes through and is fixedly connected to the hole.

[0020] The other end of the hydraulic rod 33 is hinged to the second hinge frame 34.

[0021] Example 2 Please see Figure 5-6 Furthermore, based on Example 1, a soot blowing mechanism 4 was obtained.

[0022] The soot blowing mechanism 4 includes a high-pressure air pump 41, which is fixedly connected to the right side of the L plate 31. A first high-pressure air pipe 42 is fixedly connected to the air outlet end of the high-pressure air pump 41. A telescopic air pipe 43 is fixedly connected to the other end of the first high-pressure air pipe 42. A second high-pressure air pipe 44 is fixedly connected to the other end of the telescopic air pipe 43. An air blowing hood 45 is fixedly connected to the second high-pressure air pipe 44. A first fixing plate 46 is fixedly connected to the right side of the L plate 31. A second fixing plate 47 is fixedly connected to the bottom right side of the residual electrode plate 37.

[0023] The top of the first fixing plate 46 has a hole that matches the first high-pressure air pipe 42, and the surface of the first high-pressure air pipe 42 is penetrated and fixedly connected to the hole to support the first high-pressure air pipe 42.

[0024] The second fixing plate 47 has a hole on its right side that matches the second high-pressure air pipe 44, and the surface of the second high-pressure air pipe 44 is penetrated and fixedly connected to the hole to support the second high-pressure air pipe 44.

[0025] In actual operation, after the crusher has finished cleaning the residual electrodes, the device is installed above the grid on the belt conveyor. The residual electrodes crushed by the crusher are hoisted onto the device. Then, the two hydraulic rods 33 are activated, lifting the right end of the residual electrode plate 37 and tilting it. The residual electrode plate 37 can tilt up to 80 degrees through the operation of the two hydraulic rods 33. A larger tilt angle allows the material blocks and powder on the residual electrode plate 37 to fall onto the belt conveyor and be transported away due to gravity. At the same time, the high-pressure air pump 41 is activated, generating high-pressure gas. The high-pressure gas passes through the first high-pressure air pipe 42, the telescopic air pipe 43, and the second high-pressure air pipe 44. The high-pressure gas pipe 44 is finally ejected from the blowing hood 45. The first fixing plate 46 and the second fixing plate 47 respectively support and fix the first high-pressure gas pipe 42 and the second high-pressure gas pipe 44, ensuring the stability of the gas pipe during gas transmission. The telescopic gas pipe 43 can adapt to the positional changes of the residual electrode plate 37 during tilting, ensuring that the gas pipe will not be twisted or broken due to the movement of the residual electrode plate 37, so that the high-pressure gas can be stably and continuously delivered to the blowing hood 45. The high-pressure gas ejected from the blowing hood 45 directly acts on the residual electrode surface on the residual electrode plate 37. The impact force generated by the high-pressure airflow can quickly and effectively blow off the dust, debris and loose electrolyte and other impurities attached to the residual electrode surface.
