Description

Technical Field

[0001] This utility model relates to the field of electrochemical technology, specifically providing a device for cleaning the bottom of an electrolytic cell. Background Technology

[0002] In the fields of non-ferrous metal smelting and basic chemical raw material production, electrolytic cells, as core reaction equipment, directly determine product quality, output, and production costs. During electrolysis, electrolyte components undergo electrochemical reactions under the action of direct current, and the target metal or gas is deposited on the electrodes. However, side reactions accompanying the main reaction and physical sedimentation phenomena lead to the continuous accumulation of a large amount of solid precipitate at the bottom of the cell. In the electrolysis of magnesium, the slag accumulated at the bottom of the electrolytic cell is mainly composed of settled magnesium oxide, and its accumulation height directly affects the electrolyte circulation characteristics. When the slag layer exceeds the lower edge of the cathode plate, it significantly alters the current distribution and has a serious negative impact on current efficiency. Similarly, in aluminum electrolytic cells, sediment forms at the bottom of the cell after shutdown.

[0003] Currently, the cleaning of electrolytic cells after use usually involves scraping and cleaning the anode and cathode mud on the side walls of the electrolytic cells. The precipitates that are cleaned off are then rinsed with cleaning fluid and discharged through the mud discharge port at the bottom of the electrolytic cells. However, some stubborn precipitates have accumulated at the bottom of the cells over time and are difficult to clean by washing with water. Utility Model Content

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] The following is combined Figures 1 to 4 The embodiments shown illustrate the technical solution of this utility model: This utility model embodiment provides an electrolytic cell bottom sludge removal device, such as... Figure 1 As shown, in an exemplary embodiment, the system includes: a platform 1, a reciprocating drive 2, a shovel head 3, a collection box 4, and a conveyor 5. A roller 12 is provided on one side of the platform 1; the reciprocating drive 2 is mounted on the other side of the platform 1; the shovel head 3 is disposed at the drive end of the reciprocating drive 2, and the reciprocating drive 2 provides a horizontal reciprocating driving force to the shovel head 3; the collection box 4 is mounted on the platform 1 and located at the end of the platform 1 away from the reciprocating drive 2; the conveyor 5 is disposed between the shovel head 3 and the collection box 4, and the conveyor 5 is inclined along the collection opening of the collection box 4 to the shovel head 3.

[0022] Specifically, the device is moved to the bottom of the electrolytic cell to be cleaned via rollers 12 on one side of the vehicle platform 1. The rollers 12 provide mobility for the device, allowing it to move flexibly around the bottom of the electrolytic cell to adapt to different cleaning needs and improve the device's mobility. The reciprocating drive 2 is activated, providing a horizontal reciprocating driving force to the shovel head 3, causing the shovel head 3 to move horizontally back and forth at the bottom of the cell. The reciprocating drive 2 can continuously shovel stubborn sediment at the bottom of the cell, which can more thoroughly remove stubborn sediment than a single shovel, thus improving cleaning efficiency. The shoveled sediment is transported to the conveyor 5 located between the shovel head 3 and the collection box 4. The conveyor 5 is set at an inclination, and the inclination angle creates a height difference, allowing the sludge at the shovel head 3 to be smoothly transported to the collection box 4, which has a higher opening position, to prevent the sludge from accumulating near the shovel head 3, ensuring the continuity of the cleaning process and realizing mechanized and efficient cleaning operations.

[0023] See Figure 2In an exemplary embodiment, the reciprocating drive component 2 includes: a mounting frame 27, a guide rod 21, a movable sleeve 22, a first connecting rod 23, a servo motor 26, a drive disk 25, and a second connecting rod 24. The mounting frame 27 is disposed on the side of the vehicle plate 1 away from the roller 12 and located at the end of the vehicle plate 1 near the shovel head 3. The guide rod 21 is mounted on the mounting frame 27 and is disposed along the length direction of the vehicle plate 1. The movable sleeve 22 is sleeved on the guide rod 21 and has a sliding degree of freedom along the guide rod 21. One end of the first connecting rod 23 is connected to the movable sleeve 22, and the other end is connected to the shovel head 3. The servo motor 26 is mounted on the vehicle plate 1. The drive disk 25 is disposed at the output end of the servo motor 26. One end of the second connecting rod 24 is rotatably connected to the edge of the drive disk 25, and the other end is rotatably connected to the movable sleeve 22.

[0024] Specifically, the mounting bracket 27 provides stable support for components such as the guide rod 21 and the movable sleeve 22, ensuring the overall stability of the reciprocating drive component 2 and preventing the movable sleeve 22 from shaking or shifting during movement. The guide rod 21 is set along the length of the vehicle plate 1 and cooperates with the movable sleeve 22 sleeved on it to limit the movement trajectory of the movable sleeve 22, so that the movable sleeve 22 can only move along the axial direction of the guide rod 21, thereby ensuring that the shovel head 3 only performs reciprocating motion in the horizontal direction, ensuring accurate shoveling direction and improving the targeting of shoveling. The movable sleeve 22 is sleeved on the guide rod 21 and can slide smoothly along the guide rod 21, converting the power transmitted by the connecting rod 24 into linear motion and transmitting it to the shovel head 3 through the connecting rod 1 23. The connecting rod 1 23 connects the movable sleeve 22 and the shovel head 3, realizing... The power transmission between the two ensures that the movement of the movable sleeve 22 can effectively drive the shovel head 3. The servo motor 26, as a power source, can provide a stable and controllable driving force. By adjusting the output parameters of the servo motor 26, the rotation speed of the drive disc 25 can be controlled, thereby adjusting the reciprocating frequency and amplitude of the shovel head 3 to adapt to different silt conditions. The drive disc 25 rotates under the drive of the servo motor 26, and the circular motion is converted into the linear reciprocating motion of the movable sleeve 22 through the connecting rod 24 on the edge, realizing the conversion of the power transmission form. The structure is simple and the transmission efficiency is high. The two ends of the connecting rod 24 are rotatably connected to the drive disc 25 and the movable sleeve 22 respectively, ensuring that the circular motion of the drive disc 25 can be smoothly converted into the reciprocating sliding of the movable sleeve 22, reducing the jamming in the motion transmission process.

[0025] In an exemplary embodiment, lubricating oil is applied to both the guide rod 21 and the inner circumference of the movable sleeve 22.

[0026] Specifically, after applying lubricating oil to the guide rod 21 and the inner circumference of the movable sleeve 22, when the movable sleeve 22 slides along the guide rod 21, the lubricating oil forms an oil film on the contact surface of the two. The lubricating oil can reduce the coefficient of friction between the guide rod 21 and the movable sleeve 22, reduce the frictional force when the two slide relative to each other, make the sliding of the movable sleeve 22 along the guide rod 21 smoother, reduce the power loss of the servo motor 26, and improve the working efficiency of the reciprocating drive component 2; at the same time, it reduces the wear caused by friction, extends the service life of the guide rod 21 and the movable sleeve 22, and reduces the maintenance frequency and cost of the device; in addition, the lubricating oil can also play a sealing and rust-preventing role, preventing impurities from entering the gap between the two and affecting the sliding, and avoiding the guide rod 21 and the movable sleeve 22 from getting stuck due to corrosion.

[0027] See Figure 3 In an exemplary embodiment, a wedge-shaped strip 51 is provided on the conveying surface of the conveyor 5.

[0028] Specifically, the wedge-shaped strip 51 can increase the friction between the conveying surface of the conveyor 5 and the sludge. When the conveyor 5 is tilted, it can effectively prevent the sludge from sliding down the conveying surface under the action of gravity, ensuring that the sludge can be stably conveyed to the collection box 4, improving the conveying efficiency and conveying volume of the sludge, and reducing the loss of sludge during the conveying process.

[0029] See Figure 3 In an exemplary embodiment, protective plates 52 are provided on both sides of the conveyor 5.

[0030] Specifically, the side guards 52 are located at the edges of the conveying surface. The guards 52 can prevent sludge from falling from both sides of the conveyor 5, avoid sludge loss from the sides during the conveying process, ensure that more sludge is conveyed to the collection box 4, improve the reliability and efficiency of the conveying, and at the same time reduce the secondary pollution of the bottom environment of the electrolytic cell by the falling sludge.

[0031] See Figure 4 In an exemplary embodiment, the system further includes a cleaning component 6, which includes a water tank 61, a water spray component 62, and a cleaning roller 63. The water tank 61 is installed on one side of the collection box 4. The water spray component 62 is connected to the water tank 61 and is located on the side of the collection box 4 away from the reciprocating drive component 2. The cleaning roller 63 is disposed in the water spraying direction of the water spray component 62, and a drive motor is provided at one end of the cleaning roller 63.

[0032] Specifically, the water tank 61 provides a continuous water source for the water spraying component 62, ensuring the continuity of the water spraying operation during the cleaning process. The water sprayed by the water spraying component 62 can moisten and soften the residual sludge at the bottom of the tank, reduce the stickiness and hardness of the sludge, and re-wet the stubborn sediment that was not completely cleaned by the shovel head 3 in the first cleaning. Then, the cleaning roller 63 cleans it. At the same time, the water can also wash away the loose sludge, enhancing the cleaning effect. The cleaning roller 63 rotates under the drive of the drive motor, and scrapes and cleans the sludge that has been moistened by water through mechanical action. It treats the stubborn sludge that was not cleaned by the shovel head 3 and the conveyor 5, making the cleaning of the bottom of the electrolytic cell more thorough and improving the overall cleanliness of the cleaning.

[0033] See Figure 4 In an exemplary embodiment, the water spraying component 62 includes a water pump 623, a connecting pipe 622, and an installation pipe 621. The input end of the water pump 623 is connected to the water tank 61. One end of the connecting pipe 622 is connected to the output end of the water pump 623. The installation pipe 621 is closed at both ends, and the middle part of the installation pipe 621 is connected to the other end of the connecting pipe 622. The installation pipe 621 is provided with a plurality of high-pressure nozzles 624, and each high-pressure nozzle 624 is arranged facing the cleaning roller 63.

[0034] Specifically, the water pump 623 provides power to the water flow, ensuring that the water can be delivered to the installation pipe 621 and form high pressure, thereby enhancing the impact force of the water flow; the connecting pipe 622 connects the water tank 61 and the installation pipe 621 to ensure smooth water delivery; the installation pipe 621 is closed at both ends, which can concentrate the water pressure so that all the water flow is sprayed out from the high-pressure nozzle 624; multiple high-pressure nozzles 624 are set towards the cleaning roller 63, which can make the high-pressure water flow evenly sprayed on the surface of the cleaning roller 63 and the corresponding cleaning area of ​​the cleaning roller 63. On the one hand, the high-pressure water flow can further soften the sludge in the area and enhance the scraping effect of the cleaning roller 63; on the other hand, it can wash away the sludge adhering to the surface of the cleaning roller 63 and improve the cleaning efficiency of the cleaning component 6.

[0035] See Figure 1 In an exemplary embodiment, the vehicle panel 1 is symmetrically provided with a fixing frame 11 along its width direction.

[0036] Specifically, the symmetrically arranged fixing frame 11 can balance the force on both sides of the vehicle plate 1 in the width direction, avoid the vehicle plate 1 from tilting or deforming due to excessive force on one side, enhance the stability and firmness of the overall structure of the device, ensure that the device remains stable during movement and dredging operations, and reduce the adverse effects of structural instability on the dredging effect.

[0037] In an exemplary embodiment, a crane (not shown) is connected to one end of the mounting frame 11 away from the vehicle platform 1, and the crane provides the device with the driving force for movement.

[0038] The overhead crane is a single- or double-girder bridge crane, which is existing technology known to those skilled in the art and will not be described further here.

[0039] Specifically, the overhead crane, as a power source, can drive the device to move over a wide range, including horizontal movement and vertical lifting within the electrolytic cell. This overcomes the limitation that the rollers 12 of the car platform 1 can only move on the bottom plane of the cell, enabling the device to reach different locations within the electrolytic cell for sludge removal and improving the device's range of movement and flexibility. At the same time, the overhead crane can easily lift the device into or out of the electrolytic cell, facilitating the installation and relocation of the device.

[0040] See Figure 4 In an exemplary embodiment, the cleaning roller 63 includes a roller and a plurality of scrapers, wherein the roller is rotatably mounted at the bottom of the collection box 4 and is located in the water spraying direction of the water spraying component 62; the plurality of scrapers are respectively disposed on the outer peripheral surface of the roller and are distributed in an array along the axial direction of the roller.

[0041] In some embodiments, the scraper may also be replaced by bristles, steel brush, etc.

[0042] Specifically, the roller provides a mounting base for the scraper and transmits the power of the drive motor to rotate the scraper. The two-dimensional array of scrapers or bristles increases the contact area and frequency with the sludge. During the rotation of the roller, multiple scrapers or bristles scrape the sludge from different angles and positions, resulting in a more comprehensive coverage and avoiding dead corners. At the same time, it enhances the scraping force on stubborn sludge. Combined with the flushing effect of the water spray component 62, it further improves the cleaning efficiency and thoroughness of the cleaning roller 63.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
