Description

Technical Field

[0001] This invention relates to the field of electrolytic cell technology, specifically to an electrolytic cell for nickel electrolytic production. Background Technology

[0002] In existing nickel electrolysis diaphragm electrolysis processes, wooden wedges are typically driven into the gap between the diaphragm frame and the inner wall of the electrolytic cell for fixation. This method has several drawbacks: First, wooden wedges are consumables, numerous in number, and discarded after each disassembly, increasing material costs and making the operation cumbersome. Second, relying solely on manual hammering of wooden wedges makes it difficult to achieve precise and consistent positioning, which can easily cause the diaphragm frame to shift during electrolysis, affecting the stable separation of the cathode and anode areas within the electrolytic cell and ultimately damaging the quality of the electrolytic nickel product.

[0003] Furthermore, wooden wedges exert continuous radial compressive force on the sidewalls of the electrolytic cell during long-term, repeated use, easily causing irreversible "bulging" plastic deformation of the cell and significantly shortening its service life. Simultaneously, installing, tightening, and removing numerous wooden wedges is a heavy manual task, significantly increasing the labor intensity of employees and becoming a bottleneck restricting production efficiency and economic benefits. Therefore, there is an urgent need for a diaphragm frame fixing device that can achieve precise positioning, does not damage the cell, and is easy to operate. Summary of the Invention

[0004] The purpose of this invention is to provide an electrolytic cell for nickel electrolysis production to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: An electrolytic cell for nickel electrolysis production includes an electrolytic cell body. Several sets of diaphragm frames are placed along the length of the electrolytic cell body, and the diaphragm frames are arranged along the width of the electrolytic cell body. Several pairs of locking strips are correspondingly provided between adjacent sets of diaphragm frames and between the outermost diaphragm frame and the inner wall of the electrolytic cell body. The locking strips are integrally formed with the inner wall of the electrolytic cell body and are located on the upper part of the inner wall. The two ends of each pair of locking strips are used to lock two adjacent diaphragm frames. A rotating mechanism is provided on the outside of the electrolytic cell body, and a reinforcing mechanism is provided on one side of the rotating mechanism; The reinforcement mechanism includes a support box, which is disposed on the top of the rotating mechanism. A threaded rod is rotatably connected to the inner wall of the support box, and a threaded block is threadedly connected to the outer wall of the threaded rod. A fixed shaft is fixedly connected to the outer side of the threaded block, and a clamping arm is fixedly connected to the end of the fixed shaft away from the threaded block.

[0006] The support box has a slot on its outer side, and the fixed shaft passes through the slot and moves, so that the fixed shaft can move through the slot.

[0007] The threaded rod is divided into four sections, each of which has external threads with opposite directions of rotation at both ends.

[0008] The threaded block is slidably connected to the inner wall of the support box, the threaded rod passes through the left side of the support box and rotates, and a handwheel is fixedly connected to the left end of the threaded rod, so that the threaded rod can be rotated by the handwheel.

[0009] One side of the clamping arm is in close contact with the outside of the diaphragm frame, so that the clamping arm can clamp and position the diaphragm frame.

[0010] The diaphragm frame is a plate-like structure, and all diaphragm frames are the same size and arranged parallel to each other.

[0011] The positioning strip is vertically arranged along the inner wall of the electrolytic cell, and a space is reserved between its bottom and the bottom of the cell for the flow of anode mud.

[0012] The number of diaphragm frames is four, and the number of locking strips is five pairs.

[0013] The rotating mechanism includes a support plate, which is fixedly connected to the outside of the electrolytic cell. A T-shaped shaft is rotatably connected to the inner wall of the support plate. A knob is threadedly connected to the outer wall of the T-shaped shaft. A support arm is fixedly connected to the outer wall of the T-shaped shaft. The rotating support box can be rotated to facilitate the disassembly, assembly, inspection and maintenance of the internal components of the electrolytic cell.

[0014] One side of the knob is in contact with the outer side of the support plate, and the support arm is fixedly connected to the bottom of the support box to ensure the stability of the support arm's position.

[0015] Compared with the prior art, the present invention provides an electrolytic cell for nickel electrolysis production, which has the following beneficial effects: 1. This invention integrates the positioning strip with the inner wall of the electrolytic cell to create a precise positioning slot, which solves the problem of bulging and deformation of the cell caused by wooden wedges, thereby extending the service life of the main structure of the electrolytic cell. At the same time, the integrated positioning strip ensures that all diaphragm frames are arranged in parallel and at equal intervals, thereby achieving the precision and stability of the diaphragm bag separation area, effectively improving current efficiency and product quality of electrolytic nickel. Its operation method is also simple enough, requiring only hoisting to complete the installation and positioning of the diaphragm frame, significantly reducing the labor intensity and operation time of workers. 2. The reinforcement and rotation mechanisms added in this invention further enhance the stability and maintainability of the equipment. Specifically, by driving the clamping arm with a thread, a controllable auxiliary clamping force can be applied to the diaphragm frame from the top, forming a double fixation with the bottom locking strip. This effectively prevents the diaphragm frame from micro-movements caused by electrolyte flow or production disturbances, ensuring absolute stability during long-term operation. The rotation support structure allows the entire reinforcement mechanism to rotate outward, leaving a spacious and unobstructed maintenance space inside the electrolytic cell, facilitating the inspection, cleaning, and replacement of internal components.

[0018] 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.

[0019] This invention provides the following technical solutions: Example 1 Combination Figures 1 to 6 An electrolytic cell for nickel electrolysis production includes an electrolytic cell body 1. Several sets of diaphragm frames 2 are placed inside the electrolytic cell body 1 along its length direction, and the diaphragm frames 2 are arranged along the width direction of the electrolytic cell body 1. Several pairs of locking strips 3 are provided between two adjacent sets of diaphragm frames 2 and between the outermost diaphragm frame 2 and the inner wall of the electrolytic cell body 1. The locking strips 3 are integrally formed with the inner wall of the electrolytic cell body 1 and are located on the upper part of the inner wall. The two ends of each pair of locking strips 3 are used to lock two adjacent diaphragm frames 2 respectively. A rotating mechanism 5 is provided on the outside of the electrolytic cell body 1, and a reinforcing mechanism 4 is provided on one side of the rotating mechanism 5; The reinforcement mechanism 4 includes a support box 41, which is located on the top of the rotating mechanism 5. A threaded rod 42 is rotatably connected to the inner wall of the support box 41, and a threaded block 43 is threadedly connected to the outer wall of the threaded rod 42. A fixed shaft 44 is fixedly connected to the outer side of the threaded block 43, and a clamping arm 45 is fixedly connected to the end of the fixed shaft 44 away from the threaded block 43.

[0020] The support box 41 has a slot on the outside, and the fixed shaft 44 passes through the slot and moves, so that the fixed shaft 44 can move through the slot.

[0021] The threaded rod 42 is divided into four segments, each of which has external threads with opposite directions of rotation at both ends.

[0022] The threaded block 43 is slidably connected to the inner wall of the support box 41. The threaded rod 42 passes through the left side of the support box 41 and rotates. A handwheel is fixedly connected to the left end of the threaded rod 42, which facilitates the rotation of the threaded rod 42 by the handwheel.

[0023] One side of the clamping arm 45 is in contact with the outer side of the diaphragm frame 2, so that the clamping arm 45 can clamp and position the diaphragm frame 2.

[0024] The diaphragm frame 2 is a plate-like structure, and all diaphragm frames 2 are the same size and arranged in parallel to each other.

[0025] The positioning strip 3 is vertically installed along the inner wall of the electrolytic cell 1, and a space is reserved between its bottom and the bottom of the cell for the flow of anode mud.

[0026] Specifically, in this embodiment, there are four sets of diaphragm frames 2 and five pairs of locking strips 3.

[0027] Example 2 See Figures 1 to 6 Furthermore, based on Embodiment 1, the rotating mechanism 5 includes a support plate 51, which is fixedly connected to the outside of the electrolytic cell 1. A T-shaped shaft 52 is rotatably connected to the inner wall of the support plate 51, a knob 53 is threadedly connected to the outer wall of the T-shaped shaft 52, and a support arm 54 is fixedly connected to the outer wall of the T-shaped shaft 52. The rotating support box 41 can be rotated, which facilitates the disassembly, assembly, inspection and maintenance of the internal components of the electrolytic cell 1.

[0028] The knob 53 is in contact with the outer side of the support plate 51, and the support arm 54 is fixedly connected to the bottom of the support box 41 to ensure the stability of the support arm 54.

[0029] In actual operation, when this device is used, several pairs of vertical locking strips 3 are pre-cast on the upper part of the inner wall of the electrolytic cell 1 during its manufacturing process. During production, the operator only needs to use a crane to place the diaphragm frame 2 from top to bottom into the fixed slots formed by the corresponding pair of locking strips 3. The bottom of the diaphragm frame 2 naturally rests on the bottom plate of the electrolytic cell 1 to bear the main weight, while its upper sides are firmly restricted by the locking strips 3, thereby achieving precise positioning and zero movement in the horizontal direction. This structure ensures that all diaphragm frames 2 are arranged in parallel and equidistantly, guaranteeing the stable separation of the cathode and anode areas.

[0030] On the other hand, the space reserved at the bottom of the positioning strip 3 ensures that the anode mud generated by electrolysis can settle without obstruction and flow freely at the bottom of the tank without affecting the normal process; the entire device thus achieves rapid and accurate installation and fixation of the diaphragm frame, thereby eliminating the various drawbacks of using wooden wedges.

[0031] Rotate knob 53 so that knob 53 no longer presses against support plate 51. At this time, support box 41 can be rotated around the axis of T-shaped shaft 52, so that clamping arm 45 can be moved out of the electrolytic cell 1, which facilitates further disassembly, assembly, inspection and maintenance of internal parts of electrolytic cell 1. Similarly, support box 41 can also be reinforced.

[0032] The handwheel is turned to rotate the threaded rod 42. The threaded block 43 can slide and limit its movement on the inner wall of the support box 41. The threaded rod 42 and the threaded block 43 are threadedly connected, so that the rotational motion of the threaded rod 42 is converted into the linear motion of the threaded block 43. The threaded block 43 can drive the clamping arm 45 to move through the fixed shaft 44, so that the clamping arm 45 can clamp the diaphragm frame 2, thereby ensuring the stability of the diaphragm frame 2 during use.
