Description

Technical Field

[0001] This utility model relates to the field of industrial electrolysis technology, and specifically discloses an electrolytic cell that facilitates the replacement of cell plates. Background Technology

[0002] Currently, metallic aluminum is obtained through cryolite-alumina molten salt electrolysis. Due to the special nature of the production process, a large amount of dust and electrolytic fumes (CO2, HF gas, SO2, etc.) escape from the electrolytic cell during electrolysis, causing pollution to the production workshop and the surrounding environment. In order to reduce pollution and purify the production environment, a cell cover plate (also called a cell plate) is installed on the electrolytic cell to prevent the escape of dust and fumes. The cell cover plate has the functions of preventing pollutants from escaping, maintaining the negative pressure balance of gas collection in the cell, preventing foreign objects from falling into the cell, protecting the safety of personnel in the workplace, and insulating the cell.

[0003] For example, utility model patent CN213866449U discloses an electrolytic cell cover and an electrolytic cell, including: a cell cover plate, slidably laid at the opening of the electrolytic cell; a power mechanism for providing power; and a transmission mechanism connected to the power mechanism and the cell cover plate respectively. When the power mechanism is running, the transmission mechanism drives the cell cover plate to slide along a first direction or a second direction to open or close the opening. This method allows the power mechanism to provide power and drive the cell cover plate to slide on the electrolytic cell body, eliminating the need for workers to remove the cell cover plate and greatly reducing the labor intensity of workers. Furthermore, because the method of opening and closing the cell cover plate is simple and labor-saving, it can also largely avoid the problem of not closing the electrolytic cell opening in time due to worker inertia or physical limitations.

[0004] Existing electrolytic cell equipment only addresses the issue of changing the way the cell cover is opened. However, when the cell cover is deformed, cracked, or damaged due to long-term high temperature and fluoride corrosion and needs to be replaced, it is still necessary to manually remove the cell cover from the transmission mechanism and then replace it with a new one. During the manual replacement process, toxic gases inside the electrolytic cell will escape, which will not only harm the health of the workers but also pollute the surrounding environment. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide an electrolytic cell that facilitates the replacement of the cell plates, so as to solve the technical problem that toxic gas inside the electrolytic cell will escape during the replacement process of the existing cell plate replacement device.

[0006] To achieve the above objectives, this utility model provides the following technical solution: It includes an electrolytic cell, a cell plate, a base, a movable frame, two connecting rods, and a replacement mechanism. The cell plate is mounted on the electrolytic cell, and the base is fixedly connected to the electrolytic cell. A slidable movable frame is provided between the electrolytic cell and the base. Two connecting rods are fixedly connected to the movable frame, and the replacement mechanism is mounted on the two connecting rods. When it is necessary to replace the cell plate on the electrolytic cell, the movable frame is manually pushed to move between the electrolytic cell and the base. The connecting rods connect the replacement mechanism and the movable frame, and the replacement mechanism is moved to the cell plate that needs to be replaced via the movable frame.

[0007] Furthermore, the replacement mechanism includes a first replacement frame, a partition, a moving device, a first hydraulic rod, a connecting frame, a bidirectional hydraulic rod, two fixed plates, a sliding door, and a replacement device. The first replacement frame is fixedly connected to the connecting rod. The first replacement frame has a first replacement cavity and a second replacement cavity. The partition is provided between the first replacement cavity and the second replacement cavity. The first replacement cavity communicates with the second replacement cavity. The moving device is provided on the first replacement frame. The first hydraulic rod is provided on the moving device. The telescopic end of the first hydraulic rod is fixedly connected to the connecting frame. The bidirectional hydraulic rod is provided in the connecting frame. Two fixed plates are fixedly connected to both ends of the bidirectional hydraulic rod. The two fixed plates are slidably mounted on two fixed slots opened in the slotted plate. The sliding door is provided on the first replacement frame. The replacement device is provided on the first replacement frame. When the moving device moves to the slot plate that needs to be replaced, the moving device on the first replacement frame is activated. This moving device drives the first hydraulic rod to move above the slot plate. At this time, the telescopic end of the first hydraulic rod drives the connecting frame towards the slot plate. During this movement, the bidirectional hydraulic rod inside the connecting frame drives the two fixed plates to move, aligning the width of the two fixed plates with the fixed slots on the slot plate. The first hydraulic rod places the two fixed plates into the fixed slots on the slot plate. The bidirectional hydraulic rod then drives the two fixed plates to clamp the fixed slots. After the fixed plates clamp and fix the fixed slots on the slot plate, the first hydraulic rod drives the slot plate to rise. During this rising process, toxic gases from the electrolytic cell will escape. The first replacement frame then provides protection. As the first hydraulic rod drives the slot plate to rise, the replacement device pushes a new slot plate into the first replacement chamber of the first replacement frame. At this time, the damaged slot plate held by the bidirectional hydraulic rod is on the first hydraulic rod. A hydraulic rod drives the damaged cell plate to press against the new cell plate, making the new cell plate fit more tightly against the electrolytic cell. Since the damaged cell plate and the new cell plate have the same area, the mutual pressing of the two cell plates effectively prevents the new cell plate from warping when it enters the first replacement chamber. After the damaged cell plate presses the new cell plate back into place, the moving device moves the cell plate on the first hydraulic rod into the second replacement chamber. At this time, the bidirectional hydraulic rod moves the two fixing plates, ending the fixing of the groove on the damaged cell plate and placing the damaged cell plate into the second replacement chamber. The second damaged cell plate is then fixed by a partition. When the second replacement chamber is full of cell plates, the sliding door is pulled up, and the damaged cell plates in the second replacement chamber can be removed and processed. During the replacement of damaged cell plates, the replacement mechanism can effectively prevent toxic gases from escaping into the workshop and harming the health of workers, while also reducing the pollution of the environment by toxic gases.

[0008] Furthermore, the moving device includes a moving frame, a motor, a threaded rod, and a moving block. The moving frame is fixedly connected to the first replacement frame. The motor is disposed within the moving frame, and the threaded rod is fixedly connected to the power output end of the motor. The threaded rod passes through the moving frame. The moving block, which can slide through the threaded rod, is disposed within the moving frame and is fixedly connected to the first hydraulic rod. When it is necessary to drive the first hydraulic rod to move, the moving device drives the first hydraulic rod to move. When the damaged slotted plate is clamped on the first hydraulic rod, the moving device drives the first hydraulic rod to move into the second replacement chamber and place the damaged slotted plate into the second replacement chamber.

[0009] Furthermore, the replacement device includes a second replacement frame, a cover plate, and a conveyor belt. The second replacement frame is mounted on the first replacement frame, the cover plate is mounted on the second replacement frame, the conveyor belt is disposed inside the second replacement frame, and a replacement slot is formed on the second replacement frame. When a new cell plate needs to be transported to the first replacement chamber to be fitted with the electrolytic cell, the replacement device pushes the new cell plate into the first replacement chamber, and then the first hydraulic rod cooperates to fit it with the electrolytic cell. The replacement device eliminates the need for manual placement of the new cell plate on the electrolytic cell, and also avoids the problem of contact with toxic gases inside the electrolytic cell when manually replacing the new cell plate.

[0010] Furthermore, the replacement device also includes two limiting rods and several springs. The two limiting rods are slidably mounted on both sides of the first replacement frame, and the several springs are respectively disposed between the corresponding limiting rods and the first replacement frame. When the new slot plate is conveyed into the first replacement chamber by the conveyor belt, it will first contact the two limiting rods, which will fix the slot plate in the first replacement chamber. When the new slot plate is completely in the first replacement chamber, the damaged slot plate held by the first hydraulic rod can press against the new slot plate. During the pressing process, the limiting rods will be pushed into the first replacement frame, and the springs will be compressed. After the new slot plate is in contact with the electrolytic cell, the slot plate will stop pressing against the limiting rods. At this time, the limiting rods will be reset by the springs. The mutual pressing of the entire slot plate can effectively prevent the slot plate from warping during the process of entering the first replacement chamber and contacting the electrolytic cell.

[0011] The working principle and beneficial effects of this solution are as follows:

[0012] When the cell plate on the electrolytic cell is damaged and needs to be replaced, the moving frame moves the first replacement frame to the damaged cell plate. At this time, the motor drives the threaded rod to rotate, and the threaded rod drives the moving block to slide within the moving frame. As the moving block moves, it drives the first hydraulic rod to move. After the first hydraulic rod is aligned with the fixed groove on the cell plate, the first hydraulic rod drives the connecting frame to move to the fixed groove on the cell plate. Then, the bidirectional hydraulic rod is activated to clamp and fix the fixed plate to the fixed groove on the cell plate. After fixing, the first hydraulic rod drives the cell plate to move upward. When the cell plate is separated from the electrolytic cell, toxic gases inside the electrolytic cell will escape. At this time, the first and second replacement frames seal the toxic gases, preventing them from escaping and harming the health of workers during the cell plate replacement process, and also reducing environmental pollution.

[0013] After the damaged cell plate is lifted by the first hydraulic rod, the conveyor belt in the second replacement frame can be activated. The conveyor belt pushes the new cell plate through the replacement slot into the first replacement chamber of the first replacement frame. Since the first hydraulic rod holds the previously damaged cell plate, it drives the damaged cell plate to press against the new cell plate. Because the damaged cell plate and the new cell plate are the same size, the force-bearing surface of the new cell plate is more uniform, preventing the new cell plate from warping during the process of attaching to the electrolytic cell. The damaged cell plate held on the first hydraulic rod is moved to the second replacement chamber by the motor. At this time, the damaged cell plate can be placed into the first replacement chamber.

Detailed Implementation

[0019] The following detailed description illustrates the specific implementation method:

[0020] Example

[0021] like Figures 1 to 3 As shown, an electrolytic cell for easy plate replacement is disclosed, comprising an electrolytic cell 1, several plate 2, a base 3, a movable frame 4, two connecting rods 5, and a replacement mechanism. Several plate 2 are disposed on the electrolytic cell 1. The base 3 is fixedly connected to the electrolytic cell 1.

Facing the electrolytic cell 1, the telescopic end of the first hydraulic rod 11 is fixedly connected to a connecting frame 12. The connecting frame 12 extends through both ends, and a bidirectional hydraulic rod 13 is installed inside the connecting frame 12. Two fixing plates 14 are fixedly connected to both ends of the bidirectional hydraulic rod 13. The fixing plates 14 are L-shaped and can respectively engage with two fixing slots 19 opened on the tank plate 2. A sliding door 15 is slidably mounted on the first replacement frame 9 and located near the second replacement chamber 17. A replacement device is fixedly connected to the first replacement frame 9 and located near the first replacement chamber 16. The replacement device is used to transport a new tank plate 2 into the first replacement chamber 16. Figure 2 and Figure 3 As shown.

[0023] The moving device includes a moving frame 20, a motor 21, a threaded rod 22, and a moving block 23. The moving frame 20 is fixedly connected to the first replacement frame 9 and communicates with the first replacement cavity 16 on the first replacement frame 9. The motor 21 is fixedly connected inside the moving frame 20. The threaded rod 22 is fixedly connected to the power output shaft of the motor 21 and rotatably connected to the moving frame 20. A slidable moving block 23 is provided inside the moving frame 20. The moving block 23 is threadedly connected to the threaded rod 22 and fixedly connected to the first hydraulic rod 11. Figure 2 As shown.

[0024] The replacement device includes a second replacement frame 24, a cover plate 25, a conveyor belt 26, two limiting rods 27, and several springs 28. The second replacement frame 24 is fixedly connected to the first replacement frame 9 and can fit against the electrolytic cell 1. The cover plate 25 is clamped onto the second replacement frame 24. A conveyor belt 26 is provided on the inner bottom wall of the second replacement frame 24. The conveyor belt 26 is existing technology. A replacement groove 30 is opened on the side of the second replacement frame 24 near the first replacement frame 9. The width of the replacement groove 30 is greater than the width of the tank plate 2. Two limiting grooves 29 are opened in the first replacement frame 9. Two slidable limiting rods 27 are respectively provided in the two limiting grooves 29. Several springs 28 are arranged between the limiting rods 27 and the limiting grooves 29. The two limiting rods 27 are used to limit the position of the tank plate 2. The side of the two limiting rods 27 near the tank plate 2 has a triangular cross section, such as... Figure 2 As shown.

[0025] In practice

[0026] When the tank plate 2 on the electrolytic cell 1 is deformed, cracked, or damaged due to long-term high temperature and fluoride corrosion and needs to be replaced, the moving frame 4 slides within the first slide rail 7 on the electrolytic cell 1 and the second slide rail 8 on the base 3. Since the first replacement frame 9 is fixed to the moving frame 4 by the connecting rod 5, when the moving frame 4 moves, it will drive the first replacement frame 9 to move. The moving frame 4 drives the first replacement frame 9 to the damaged tank plate 2. At this time, the motor 21 in the moving frame 20 drives the threaded rod 22 to rotate. The threaded rod 22 drives the moving block 23 to slide within the moving frame 20. When the moving block 23 moves, it will drive the first hydraulic rod 11 to move. After the first hydraulic rod 11 is aligned with the fixed groove 19 on the tank plate 2, the first hydraulic rod 11 drives the connecting frame 12 to move. When the connecting frame 12 drives the fixed plate 14 to move to the fixed groove 19 on the tank plate 2, the bidirectional hydraulic rod 13 is activated. The bidirectional hydraulic rod 13 drives the fixed plate 14 to clamp and fix with the fixed groove 19 on the tank plate 2. After fixing, the first hydraulic rod 11 drives the tank plate 2 to move upward. When the tank plate 2 is separated from the electrolytic cell 1, the toxic gas in the electrolytic cell 1 will escape. At this time, the toxic gas can be sealed by the first replacement frame 9 and the second replacement frame 24 to prevent the toxic gas in the electrolytic cell 1 from escaping and harming the health of the workers during the replacement of the tank plate 2.

[0027] After the damaged slot plate 2 is lifted by the first hydraulic rod 11, the conveyor belt 26 in the second replacement frame 24 can be activated. The conveyor belt 26 pushes the new slot plate 2 through the replacement slot into the first replacement chamber 16 of the first replacement frame 9. As the slot plate 2 gradually enters the first replacement chamber 16, the lower end face of the slot plate 2 will contact the limiting rod 27. When the slot plate 2 is completely pushed into the first replacement chamber 16 by the conveyor belt 26, the slot plate 2 is located on the limiting rod 27. At this time, the first hydraulic rod 11 is activated. Since the first hydraulic rod 11 holds the previously damaged slot plate 2, it drives the damaged slot plate 2 to press against the new slot plate 2. Because the limiting rod 27 has a triangular cross-section, when the first hydraulic rod 11 drives the damaged slot plate 2 to press against the new slot plate 2, it will squeeze the limiting rod 27 into the limiting groove 29. When the limiting rod 27 is squeezed into the limiting groove 29, at the same time... The spring 28 in the limiting groove 29 will be squeezed to store elastic potential energy for the subsequent reset of the limiting rod 27. At this time, the new plate 2 will be pressed onto the electrolytic cell 1 by the damaged plate 2. When the first hydraulic rod 11 moves the damaged plate 2 upward, it will also come into contact with the limiting rod 27. When the first hydraulic rod 11 continues to move the damaged plate 2, it will squeeze the limiting rod 27 into the limiting groove 29. The limiting rod 27 prevents the new plate 2 from shifting position when it enters the first replacement chamber 16, so that it cannot be completely attached to the electrolytic cell 1. The process of the damaged plate 2 being squeezed onto the new plate 2 by the first hydraulic rod 11 also prevents the new plate 2 from warping during the process of attaching to the electrolytic cell 1 because the force surface of the new plate 2 is more uniform. After the new plate 2 in the second replacement frame 24 is used up, the cover plate 25 is opened directly, and the new plate 2 is placed into the second replacement frame 24.

[0028] At this time, the motor 21 drives the threaded rod 22 to rotate, and the threaded rod 22 drives the first hydraulic rod 11 on the moving block 23 to move. This moves the damaged slotted plate 2 held by the first hydraulic rod 11 into the second replacement chamber 17. The partition 10 limits the slotted plate 2 placed in the second replacement chamber 17. At this time, the first hydraulic rod 11 descends and places the damaged slotted plate 2 into the second replacement chamber 17. Then, the bidirectional hydraulic rod 13 ends the clamping of the slotted plate 2. At this time, the motor 21 can drive the first hydraulic rod 11 to move back into the first replacement chamber 16 to prepare for the next replacement. When the space in the second replacement chamber 17 is filled with the damaged slotted plate 2, the sliding door 15 is pulled out, and the damaged slotted plates 2 can be taken out and processed.

[0029] The above description is merely an embodiment of this utility model, and common knowledge such as specific structures and characteristics in the solution is not described in detail here. It should be noted that those skilled in the art can make several modifications and improvements without departing from the structure of this utility model, and these should also be considered within the protection scope of this utility model. These modifications and improvements will not affect the effectiveness of the implementation of this utility model or its practicality.
