Description

Technical Field

[0001] This utility model relates to the field of maintenance and cleaning devices, and in particular to a cleaning device for maintaining an electrolytic cell. Background Technology

[0002] With the development of industries such as chemical engineering and metallurgy, the application of large-scale electrolytic cells is becoming increasingly widespread. During electrolysis, the electrolyte inside the electrolytic cell comes into contact with air at high temperatures, forming a hard crust on its surface. This crust has a Mohs hardness of 3 to 4, similar to marble, and is usually quite thick. If not cleaned in time, it will thicken further. This crust not only hinders the introduction of anolyte current, affecting electrolysis efficiency, but may also trigger an anolyte effect, leading to a sudden voltage surge and reaction stagnation.

[0003] Currently, electric hammers are commonly used in the industry to break up hard crusts inside electrolytic cells. However, this method has significant drawbacks. In addition, electric hammer work is physically demanding, and long-term use can easily lead to occupational injuries such as lumbar muscle strain and arm vibration syndrome for operators. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a cleaning device for maintaining electrolytic cells, which has the advantages of being suitable for large electrolytic cells, highly efficient and safe, and reducing labor intensity, thus solving some of the problems mentioned in the background technology.

[0005] This utility model provides the following technical solution: a cleaning device for maintaining an electrolytic cell, comprising a frame and a roller assembly. A hydraulic cylinder is fixedly installed on the frame near the middle of the left side. The output end of the hydraulic cylinder passes through the frame and is fixedly installed with a splitting wedge. A sleeve is slidably connected to the output end of the hydraulic cylinder on the lower side of the frame. Two sets of symmetrical side wedges are fixedly connected to the lower end of the sleeve. The side wedges are adapted to the conical surfaces of the splitting wedges. A balance plate is fixedly sleeved on the outer side of the sleeve near the lower end. Sliding sleeves are slidably sleeved on the right support legs of the frame. A lifting plate is fixedly installed between the sliding sleeves. A reduction motor is fixedly installed at the middle of the upper end of the lifting plate. A drilling head is fixedly installed on the lower output shaft of the reduction motor through a coupling.

[0006] Furthermore, each of the four upper corners of the balance plate is fixedly connected to a sliding cylinder, and each sliding cylinder is slidably connected to a sliding rod. The upper ends of the sliding rods are fixedly connected to the frame. The sliding cylinders, sliding rods, and lifting springs provide support and fixation for the sleeve and balance plate, while also allowing for lifting and lowering.

[0007] Furthermore, a lifting spring is installed between the inner bottom of the sleeve and the output end of the hydraulic cylinder. The lifting spring is located on the outside of the splitting wedge. That is, when the splitting wedge is lifted by the hydraulic cylinder after the splitting is completed, the lifting spring can be used to reset the balance plate and other structures.

[0008] Furthermore, a threaded screw is rotatably mounted on the frame near the middle of the right side. The threaded screw passes through and is threadedly connected to the lifting plate. A handwheel is fixedly mounted on the upper end of the threaded screw. Rotating the handwheel facilitates operation, reduces structural costs, and makes it easier for workers to control the drilling depth, making it more flexible.

[0009] Furthermore, the roller assembly has two sets, located at the left and right ends of the base of the frame, respectively. Adjusting components are rotatably sleeved on the connecting rod of the roller assembly near the front and rear sides. Adjusting bolts are threaded through and threaded to both ends of the adjusting components. The lower end of the adjusting bolts is threaded to the base of the frame, ensuring the rationality of the device structure, while also being simple and low in cost.

[0010] The advantages of this utility model are as follows:

[0011] 1. This cleaning device drills evenly distributed matching holes in the crust of the electrolytic cell using a drilling head. Combined with the action of splitting wedges and side wedges, it can achieve array-style splitting. The coverage area of ​​a single operation is significantly larger than that of point-by-point crushing by an electric pick. At the same time, the hydraulically driven splitting mechanism can efficiently transmit force to the inside of the crust, quickly completing the splitting and avoiding the ineffective work of frequent displacement of the electric pick. This greatly improves the crushing efficiency and effectively shortens the cleaning time of the crust of large electrolytic cells.

[0012] 2. Compared to the high-frequency vibration and debris flying risks of electric picks, this device adopts the static splitting principle, which can effectively reduce the impact damage of vibration to the electrolytic cell and avoid the safety hazards caused by the flying debris of the crust. In addition, workers do not need to carry heavy tools for high-intensity work. They only need to operate the device to complete the drilling and splitting operations, which greatly reduces the labor intensity and reduces the risk of occupational injuries such as lumbar muscle strain and arm vibration disease. Moreover, less dust is generated during the operation, which protects the respiratory health of the workers. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-4A cleaning device for maintaining an electrolytic cell includes a frame 1 and a roller assembly 16. A hydraulic cylinder 2 is fixedly installed on the frame 1 near the middle of the left side. The output end of the hydraulic cylinder 2 passes through the frame 1 and is fixedly installed with a splitting wedge 3. A sleeve 4 is slidably connected to the output end of the hydraulic cylinder 2 on the lower side of the frame 1. Two sets of symmetrical side wedges 5 are fixedly connected to the lower end of the sleeve 4. The side wedges 5 are adapted to the conical surfaces of the splitting wedges 3. A balance plate 6 is fixedly sleeved on the outer side of the sleeve 4 near the lower end. The right support leg of the frame 1 is equipped with... A sliding sleeve 10 is slidably connected, and a lifting plate 11 is fixedly installed between the sliding sleeves 10. A reduction motor 12 is fixedly installed at the middle of the upper end of the lifting plate 11. A drilling head 13 is fixedly installed on the lower output shaft of the reduction motor 12 through a coupling. After drilling evenly distributed holes in the crust in the electrolytic cell, the splitting wedge 3 and the side wedge 5 are aligned with the holes. It is worth mentioning that the diameter of the holes drilled by the drilling head 13 is matched with the maximum diameter of the splitting wedge 3 and the side wedge 5 in the initial state. Then, the hydraulic cylinder 2 is opened to make it... The output end drives the splitting wedge 3 to descend, while the lifting spring 9 is compressed. The reaction force of the lifting spring 9 causes the sleeve 4 to descend. When the splitting wedge 3 and the side wedge 5 descend into the hole, the lower end of the sleeve 4 and the balance plate 6 abut against the crust, that is, the side wedge 5 is limited to the current height. When the splitting wedge 3 continues to descend, it will push the side wedge 5 to both sides, thereby transmitting the force to the inside of the crust to achieve the splitting effect. Compared with the traditional method of using an electric pick, this device has a larger single-operation coverage area. At the same time, the electric pick requires the operator to frequently move the position to break the crust point by point, while this device can achieve array-style splitting through preset hole positions, reducing ineffective labor, reducing the workload of workers, and greatly improving the crushing efficiency. This makes it convenient for workers to quickly clean up the broken crust material. In addition, compared with the electric pick, this device can effectively reduce vibration, avoid impact damage to the electrolytic cell, and avoid the splashing of crust fragments, making it safer. It also avoids the dust generated during operation, which facilitates subsequent cleaning and protects the respiratory health of the operators.

[0020] Please see Figures 2-3 Each of the four corners of the upper end of the balance plate 6 is fixedly connected to a slide cylinder 7. Each slide cylinder 7 is slidably connected to a slide rod 8. The upper end of each slide rod 8 is fixedly connected to the frame 1. A lifting spring 9 is installed between the inner bottom of the sleeve 4 and the output end of the hydraulic cylinder 2. The lifting spring 9 is located on the outside of the splitting wedge block 3. The slide cylinder 7 and the slide rod 8 can simultaneously improve the structural strength of the sleeve 4 and the balance plate 6. When splitting the shell, the limiting and reaction force of the balance plate 6 can improve the stability of the device.

[0021] Please see Figures 1-2A threaded screw 14 is rotatably mounted on the frame 1 near the middle of the right side. The threaded screw 14 passes through and is threadedly connected to the lifting plate 11. A handwheel 15 is fixedly mounted on the upper end of the threaded screw 14. When the device is moved into the electrolytic cell, the reduction motor 12 is turned on to drive the drilling head 13 to rotate. By turning the handwheel 15, the threaded screw 14 is driven to rotate. The rotation of the threaded screw 14 can drive the lifting plate 11 to rise and fall. By lowering the lifting plate 11, the drilling head 13 is lowered, thereby drilling holes in the crust in the electrolytic cell.

[0022] Please see Figure 1 There are two sets of roller assemblies 16, located at the left and right ends of the base of the frame 1, respectively. Adjusting parts 17 are rotatably sleeved on the connecting rod of the roller assembly 16 near the front and rear sides. Adjusting bolts 18 are threaded through and threaded to both ends of the adjusting parts 17. The lower end of the adjusting bolts 18 is threaded to the base of the frame 1. By turning the adjusting bolts 18, the roller assembly 16 can be raised and lowered, so that the device is not only easy to move, but also allows the base of the frame 1 to directly contact the shell during operation, thus improving stability.

[0023] Working principle: Move this device into the electrolytic cell, turn on the reduction motor 12 to drive the drilling head 13 to rotate, turn the handwheel 15 to drive the threaded screw 14 to rotate, the threaded screw 14 can drive the lifting plate 11 to rise and fall, the lifting plate 11 drives the drilling head 13 to fall, thus the drilling head 13 drills holes in the crust in the electrolytic cell. After drilling evenly distributed holes in the crust in the electrolytic cell, align the splitting wedge 3 and the side wedge 5 with the holes, then turn on the hydraulic cylinder 2 to drive the splitting wedge 3 to fall. At the same time, the lifting spring 9 is compressed by force, the sleeve 4 falls by the reaction force of the lifting spring 9. When the splitting wedge 3 and the side wedge 5 fall into the hole, the lower end of the sleeve 4 and the balance plate 6 abut against the crust, that is, the side wedge 5 will be limited to the current height. When the splitting wedge 3 continues to fall, it will push the side wedge 5 to both sides, thus transmitting the force to the inside of the crust to achieve the splitting effect.
