Specific Embodiments

[0027] The embodiments of the technical solution of the present invention will be described in detail below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, so they are only examples and cannot be used to limit the protection scope of the present invention. The specific structure of the present invention is as Figures 1-5 shown in

[0028] Embodiment 1: A caustic soda electrolysis treatment device includes an electrolytic cell 1 fixed on the ground. A top cover 2 is provided on the top of the electrolytic cell 1. Electrode plates 4 are respectively installed on both sides of the ion exchange membrane 3 of the electrolytic cell 1. The tops of the electrode plates 4 are movably and hermetically passed through above the top cover 2. A horizontal displacement mechanism is provided above the electrolytic cell 1. Synchronous support cylinders 5 are respectively installed on both sides of the bottom of the horizontal displacement mechanism. The bottoms of the synchronous support cylinders 5 are all fixed on the ground. Lifting mechanisms 7 are installed on the tops of two sliding seats 6 arranged at intervals and symmetrically in the middle of the horizontal displacement mechanism. The lower ends of the two lifting mechanisms 7 are movably extended below the horizontal displacement mechanism and are connected to the tops of the electric picking components at their corresponding positions.

[0029] In any of the above schemes, it is preferred that the horizontal shift mechanism includes a horizontal frame 8 horizontally arranged above the electrolytic cell 1, a bidirectional lead screw 9 is arranged inside the horizontal frame 8, both ends of the bidirectional lead screw 9 are movably passed through the through holes at the corresponding ends of the horizontal frame 8 through a stepped shaft 10, a motor cavity 11 is arranged on the right side of the horizontal frame 8, a translation control motor 12 is fixedly installed inside the motor cavity 11, the motor shaft of the translation control motor 12 is fixedly connected to the stepped shaft 10 at the corresponding end of the bidirectional lead screw 9, the synchronous support posts are fixed at the bottom of both sides of the horizontal frame 8, the lead screws on the outer walls on both sides of the middle part of the bidirectional lead screw 9 have opposite rotation directions, and a sliding seat 6 is screwed and installed on the outer walls on both sides of the bidirectional lead screw 9, the front and rear ends of each sliding seat 6 are movably connected to the two sides of the horizontal frame 8, and the lifting mechanism 7 is fixedly installed on the top of the sliding seat 6.

[0030] When working, the horizontal shift mechanism relies on the translation control motor 12 as the driving force. When the translation control motor 12 is running, it can drive the bidirectional screw 9 to operate. When the bidirectional screw 9 is running, the two sliding seats 6 matched thereon can achieve relative or opposite translation. In the process of translation of the sliding seat 6, it can drive the lifting mechanism 7 thereon to follow the movement. Finally, after the lifting mechanism 7 moves into place, its piston rod is controlled to extend and retract downward to drive the electric picking component to rise and fall.

[0031] In any of the above schemes, it is preferred that the lifting mechanism 7 includes a portal frame 13 fixedly mounted on the top of the sliding seat 6, and two lifting electric cylinders 14 are arranged inside the portal frame 13 at intervals along the front and rear directions of the sliding seat 6, and the piston rod of each lifting electric cylinder 14 is movable through the through hole arranged at the corresponding position of the sliding seat 6 and extends to the bottom of the horizontal frame 8 and is fixedly connected to a connecting plate 15, and the electric picking component is fixedly installed at the bottom of the connecting plate 15.

[0032] When the lifting mechanism 7 is working, the piston rod of the lifting electric cylinder 14 is extended and retracted to achieve the purpose of controlling the lifting and lowering of the connection plate 15 at the bottom. When the connection plate 15 is lifted or lowered, the electric pickup component connected to the bottom thereof can be driven to lift or lower.

[0033] Embodiment 2: Compared with Embodiment 1, this embodiment is different in that it also includes the following technical features:

[0034] In any of the above schemes, preferably, electrode plate storage boxes 16 are installed on the ground on the left and right sides of the electrolytic cell 1, and a plurality of electrode plates 4 to be used are stored inside the storage cavity of the electrode plate storage boxes 16.

[0035] The electrode plate storage box 16 is used to store new and old electrode plates 4, realizing the temporary storage of new and old electrode plates 4 during the replacement process of the electrode plates 4.

[0036] Preferably, in any of the above solutions, a square hole 17 through which the electrode plate 4 passes is provided at the position of the top cover 2 corresponding to the electrode plate 4, and sealing strips 18 are respectively installed on the circumferential inner side walls of the square hole 17.

[0037] The sealing strip 18 mainly serves to seal the inside of the electrolytic cell 1 in the working state, improving the sealing effect of the internal environment.

[0038] Preferably, in any of the above solutions, electrode fixing mechanisms are respectively installed on both sides of the electrode plate 4 below the top cover 2, and the two electrode fixing mechanisms cooperate to clamp and position the electrode plate 4 at the current position.

[0039] Preferably, in any of the above solutions, the electrode fixing mechanism includes a fixed vertical plate 19 fixedly installed at the bottom of the top cover 2. A clamping cylinder 20 is fixedly installed on the side wall of the fixed vertical plate 19 facing the electrode plate 4. A clamping disc 21 is fixedly installed at the end of the piston rod of the clamping cylinder 20. The clamping disc 21 is used to press against the outer side wall of the upper part of the electrode plate 4 at the current position, and the two clamping discs cooperate to clamp and position the electrode plate 4.

[0040] When the electrode fixing mechanism works, it relies on the expansion and contraction of the piston rod of the clamping cylinder 20 to drive the corresponding clamping disc 21 to approach or move away from the side wall of the current electrode plate 4, thereby realizing the control of clamping and loosening of the electrode plate 4.

[0041] Preferably, in any of the above solutions, the electric picking component includes an electric claw 22. The top of the electric claw 22 is fixed to the bottom of the connection disc 15 at its corresponding position, and the electric claw 22 is used to clamp the top of the electrode plate 4 directly below it.

[0042] Specific working process: When the lifting mechanism 7 drives the connection disc 15 and the electric claw 22 at the bottom to move into place, control the two clamping parts of the electric claw 22 to clamp the electrode plate 4. When the entire electric picking component moves, it can drive the clamped electrode plate 4 to move with it.

[0043] Specific working process: When it is necessary to replace the two electrode plates 4 inside the electrolytic cell 1, the translation control motor 12 of the horizontal displacement mechanism is started through control. Relying on the operation of the translation control motor 12, the bidirectional lead screw 9 is driven to rotate. During the rotation of the bidirectional lead screw 9, the sliding seat 6 and the lifting mechanism 7 and the electric picking component thereon can be driven to shift to directly above the corresponding electrode plate 4. After reaching the position, the lifting mechanism 7 is controlled to drive the electric picking component to move down to the place, and then the electric picking component is controlled to clamp the upper two sides of the electrode plate 4. After clamping, the electrode fixing mechanism inside the electrolytic cell 1 is controlled to loosen the electrode plate 4. At this time, the lifting mechanism 7 is controlled to lift the electrode plate 4 out of the electrolytic cell 1. When the bottom of the electrode plate 4 is separated from the electrolytic cell 1, the electrode plate 4 is controlled to continue to rise a certain distance. After reaching the position, the translation control motor 12 of the horizontal displacement mechanism is controlled to rotate in the reverse direction, and the lifting mechanism 7 and the corresponding electric picking component and the clamped electrode plate 4 are controlled to move to directly above the corresponding electrode plate storage box 16, and then the lifting mechanism 7 is controlled to move down so that the electrode plate 4 is placed inside the storage cavity, and the electric picking component is loosened. At this time, the disassembly and storage of the old electrode plate 4 are completed.

[0044] Continue to control the lifting mechanism 7 to lift, and then control the sliding seat 6 of the horizontal displacement mechanism to translate, cooperate with manual operation to separate the new electrode plate 4, so that the electric picking component moves down and clamps the top of the new electrode plate 4. Finally, the clamping of the new electrode plate 4 is completed. Continue to control the electric picking component to clamp the new electrode plate 4 and operate to the corresponding position above the electrolytic cell 1 in the above-mentioned manner, and control the lifting mechanism 7 to move down to realize that the electric picking component is connected with the electrode plate 4 and moves down and is hermetically passed through the square hole 17 on the top cover 2 and installed in place. After reaching the position, the electrode fixing mechanisms on both sides are controlled to clamp the new electrode plate 4. At this time, just loosen the electric claw 22 of the electric picking component, and control the electric picking component to return to the original position. Finally, the replacement of the old and new electrode plates 4 is completed.

[0045] In summary, it can be seen that by providing a horizontal displacement mechanism, a lifting mechanism 7, and an electric pickup component, the present invention can achieve automatic clamping, displacement, and replacement of the electrode plate 4, without manual operation, reducing labor intensity and improving replacement efficiency. When replacing the electrode plate 4, the horizontal displacement mechanism can drive the lifting mechanism 7 and the electric pickup component to quickly move to the designated position, accurately complete the replacement of the new and old electrode plates 4, and reduce the equipment downtime; the sealing strip 18 installed on the circumferential inner side wall of the square hole 17 of the top cover 2 can effectively improve the sealing effect inside the electrolytic cell 1, prevent the leakage of electrolytic solution and the entry of external impurities, ensure that the electrolytic reaction proceeds in a stable environment, and improve the quality and safety of electrolytic treatment; the electrode fixing mechanism can clamp and position the electrode plate 4 to ensure the stable position of the electrode plate 4 during the electrolysis process, avoid affecting the electrolysis effect due to the shaking of the electrode plate 4, ensure the stability and continuity of the electrolytic reaction, and contribute to improving the efficiency and product quality of caustic soda electrolytic treatment; the electrode storage box 16 is used to store new and old electrode plates 4, providing a temporary storage space for the replacement process of the electrode plate 4, making the management of the electrode plate 4 more orderly, facilitating the operator to access and store the electrode plate 4, and improving work convenience; the design of the bidirectional lead screw 9 and the sliding seat 6 of the horizontal displacement mechanism enables the lifting mechanism 7 and the electric pickup component to achieve relative or opposite translation, flexibly adjust the position, adapt to the replacement requirements of electrode plates 4 at different positions, and improve the applicability and operation flexibility of the device.
