Description

Technical Field

[0001] The present invention relates to the technical field of electrochemical water treatment, and particularly relates to a cleaning device for an electrolytic cell used in electrochemical water treatment. Background Art

[0002] Electrochemical water treatment is a technology that degrades or transforms pollutants in water through chemical reactions, electrochemical processes or physical processes by means of electrodes or an externally applied electric field in an electrochemical reactor. Its core is to regulate electron transfer to directly or indirectly cause redox reactions of pollutants to achieve water purification. Currently, with the development of technology, during the operation of an alkaline electrolytic cell, bipolar plates are produced using laser cutting, welding and new composite plating surface treatment processes, resulting in characteristics such as high precision of bipolar plates, dense and void-free coatings, high coating adhesion strength and uniform coating thickness, and achieving corrosion resistance and high flatness, which is more suitable for mass production. However, in the actual production process, especially during the electrochemical water treatment process, certain impurities will accumulate on the surfaces of the electrolytic cell and bipolar plates. These impurities adsorbed on the surfaces of the electrolytic cell and bipolar plates will not only affect the circulation of the electrolyte inside the electrolytic cell, but also greatly reduce the working efficiency of the bipolar plates. Moreover, if these impurities are not cleaned for a long time, the service life of the bipolar plates will be greatly reduced. Therefore, a cleaning device is installed in the electrolytic cell. Traditional cleaning devices mainly consist of a cleaning ring, a servo motor, etc. Starting the servo motor to drive the cleaning ring to move can complete the cleaning work of the inner wall of the electrolytic cell. The structure is simple. However, in the actual working process, traditional cleaning devices do not clean the electrode plates, which will greatly reduce the working efficiency and service life of the bipolar plates. Moreover, during the cleaning process, if the impurities on the inner wall of the electrolytic cell have solidified into blocks, manual knocking is still required, which is time-consuming and laborious. Also, during the cleaning process, cleaning liquid needs to be added manually, and it cannot adjust the amount of cleaning liquid according to the actual working conditions, resulting in certain waste. Therefore, a cleaning device for an electrolytic cell used in electrochemical water treatment is provided. Summary of the Invention

[0003] The purpose of the present invention is to solve the deficiencies existing in the prior art and propose a cleaning device for an electrolytic cell used in electrochemical water treatment.

The rotating cylinder is rotatably connected to two connecting rings. The connecting rings are respectively fixedly connected to the arc-shaped cleaning frames through second connecting rods. The rotating cylinder is fixedly connected to a connecting plate. The connecting plate is annularly slidably connected to the connecting ring, and a first spring is fixedly connected between the connecting plate and the connecting ring. A control component for controlling the rotation of the connecting ring is installed in the deep groove.

[0005] Preferably, the control component includes two fixed rings fixedly installed on the outer side of the rotating cylinder. Torsion springs are fixedly connected between the two fixed rings and the clamping plates. A swing plate is swingably connected in the electrolytic cell. A third spring is fixedly connected between the swing plate and the electrolytic cell. A rotating plate is fixedly connected to the outer side of the reciprocating lead screw. An auxiliary plate is fixedly connected to the outer side of the swing plate. A clamping groove is formed in the swing plate. Two rotating plates are rotatably connected in the rotating cylinder. First connecting rods are fixedly connected to the outer sides of the two rotating plates. Sleeves are slidably connected to the outer sides of the first connecting rods. A return spring is fixedly connected between the sleeve and the first connecting rod. A clamping block is fixedly connected to the lower side of the sleeve. A limiting rod is fixedly connected to the side wall of the rotating plate. An intermediate plate is fixedly connected in the rotating cylinder. Connecting springs are fixedly connected to both sides of the intermediate plate. The other ends of the connecting springs are fixedly connected to a sliding plate. The sliding plate is slidably connected to the rotating cylinder. A plurality of limiting plates are fixedly connected to the circumferential direction of the side wall of the sliding plate.

[0006] Preferably, a limiting component is installed in the deep groove. The limiting component includes a plurality of trapezoidal plates fixedly installed at the bottom of the deep groove. Two moving rods are slidably connected to the reciprocating block up and down. Moving plates are fixedly connected to the upper sides of the two moving rods. Two triangular plates are fixedly connected to the moving plates together. Two trapezoidal rings are slidably connected to the outer side of the rotating cylinder. The two trapezoidal rings are respectively fixedly connected to the sliding plate through third connecting rods.

[0007] Preferably, a knocking component is installed in the arc-shaped cleaning frame. The knocking component includes an arc-shaped plate slidably installed in the arc-shaped cleaning frame. A square plate is fixedly connected to the side wall of the arc-shaped plate. The square plate slidably penetrates through the arc-shaped cleaning frame. A positioning plate is fixedly connected to the outer side of the square plate. A second spring is fixedly connected between the positioning plate and the arc-shaped cleaning frame. An intermediate ring is fixedly connected to the outer side of the rotating cylinder.

Moreover, during the cleaning process, when the clamping block enters the card slot, it will cause one arc-shaped cleaning frame to abut against the inner wall of the electrolytic cell and the other arc-shaped cleaning frame to abut against the side wall of the bipolar plate. Therefore, not only the inner wall of the electrolytic cell but also the side wall of the bipolar plate can be cleaned, and the cleaning effect is good; 3. Furthermore, during the cleaning process, when the rotation direction of the servo motor changes, the movement of the arc-shaped cleaning frame also changes, thereby reducing the generation of cleaning dead corners and having a wider cleaning range; 4. At the same time, the arc-shaped cleaning frame that always abuts against the inner wall of the electrolytic cell will form a knocking effect on the inner wall of the electrolytic cell, improving the cleaning effect of the arc-shaped cleaning frame on the inner wall of the electrolytic cell; 5. Finally, during the cleaning process, the flow rate of the opening will be automatically adjusted according to the amount of substances that need to be cleaned on the bipolar plate, with a high degree of automation and intelligence.

Detailed implementation manners

[0014] Refer to Figures 1 - 12 , a cleaning device for an electrolytic cell used in electrochemical water treatment, includes an electrolytic cell 1 and two arc-shaped cleaning frames 3. A plurality of pipes are fixedly connected circumferentially on the outer side of the electrolytic cell 1. Electrode plates are fixedly connected to both sides inside the electrolytic cell 1. A plurality of bipolar plates are fixedly connected inside the electrolytic cell 1, and the plurality of bipolar plates are located between the two electrode plates; When electrolysis operation is required, an appropriate amount of electrolyte (i.e., wastewater) is introduced into the electrolytic cell 1 through the lower pipeline. Then, the electrode plates and bipolar plates on both sides are energized. After energization, an oxidation reaction occurs at the anode under the action of an external electric field, and a reduction reaction occurs at the cathode. The anode loses electrons and undergoes an oxidation reaction, while the cathode gains electrons and undergoes a reduction reaction. Harmful substances are removed separately on the anode and cathode. In addition, during the electrolysis process, the pH value of the wastewater changes, and precipitates are generated to further purify the wastewater. The above are all prior arts and will not be elaborated further; As Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , a deep groove 2 is opened at the bottom inside the electrolytic cell 1. A servo motor 4 is fixedly installed inside the deep groove 2. The output end of the servo motor 4 is fixedly connected to a reciprocating lead screw 5. A reciprocating block 6 is threadedly connected to the outside of the reciprocating lead screw 5. The reciprocating block 6 is slidably connected to the deep groove 2. Two clamping plates 10 are symmetrically and fixedly connected to the upper side of the reciprocating block 6. A rotating cylinder 9 is rotatably connected between the two clamping plates 10. Two connecting rings 19 are rotatably connected to the outside of the rotating cylinder 9. The two connecting rings 19 are respectively fixedly connected to an arc-shaped cleaning frame 3 through second connecting rods 18. Two connecting plates 32 are fixedly connected to the outside of the rotating cylinder 9. The two connecting plates 32 and the connecting rings 19 are slidably connected annularly, and a first spring 33 is fixedly connected between the connecting plates 32 and the connecting rings 19. From Figure 8 it can be seen that there are two first springs 33, and the two first springs 33 are symmetrically arranged on both sides of the connecting plate 32. A control component for controlling the rotation of the connecting ring 19 is installed inside the deep groove 2. The control component includes two fixed rings 24 fixedly installed on the outside of the rotating cylinder 9. Torsion springs 23 are fixedly connected between the two fixed rings 24 and the clamping plates 10. A swing plate 40 is swingably connected inside the electrolytic cell 1. A third spring 43 is fixedly connected between the swing plate 40 and the electrolytic cell 1. A rotating plate 41 is fixedly connected to the outside of the reciprocating lead screw 5. An auxiliary plate 42 is fixedly connected to the outside of the swing plate 40. A clamping groove 8 is opened on the swing plate 40. Two rotating plates 11 are rotatably connected inside the rotating cylinder 9. First connecting rods 12 are fixedly connected to the outside of the two rotating plates 11. A sleeve 13 is slidably connected to the outside of the first connecting rod 12. A return spring is fixedly connected between the sleeve 13 and the first connecting rod 12. A clamping block 14 is fixedly connected to the lower side of the sleeve 13. A limiting rod 20 is fixedly connected to the side wall of the rotating plate 11. An intermediate plate 25 is fixedly connected inside the rotating cylinder 9. Connecting springs 26 are fixedly connected to both sides of the intermediate plate 25. The other ends of the connecting springs 26 are fixedly connected to a sliding plate 27. The sliding plate 27 is slidably connected to the rotating cylinder 9. A plurality of limiting plates 29 are fixedly connected to the circumferential side wall of the sliding plate 27; First, in the initial state, the limiting rod 20 is located between two of the limiting plates 29. That is, when the limiting rod 20 swings, it can drive the limiting plates 29 and the sliding plate 27 to rotate. From Figure 7 it can be seen that the trapezoidal ring 22 is located outside the rotating cylinder 9 and is slidably connected to the left and right sides of the rotating cylinder 9. The third connecting rod 28 passes through the side wall of the rotating cylinder 9 and is slidably connected to the left and right sides of the side wall of the rotating cylinder 9. The sliding plate 27 is located inside the rotating cylinder 9 and is slidably connected to the left and right sides of the rotating cylinder 9. From Figure 12 it can be seen that the number of the rotating plates 41 is two. Secondly, from Figure 6 it can be seen that the first connecting rod 12 and the rotating plate 11 are concentrically arranged, but the limiting rod 20 is not at the center of the rotating plate 11. That is, the limiting rod 20 and the rotating plate 11 are eccentrically connected. From Figure 4 it can be seen that the swinging plate 40 passes through the reciprocating block 6. In the initial state, the two arc-shaped cleaning frames 3 are located between the electrolytic cell 1 and the bipolar plate, and the two arc-shaped cleaning frames 3 are in contact with the inner wall of the electrolytic cell 1. When it is necessary to clean the inner wall of the electrolytic cell 1, the servo motor 4 is started. The servo motor 4 drives the reciprocating lead screw 5 to rotate. Since the reciprocating block 6 is slidably connected to the deep groove 2, the rotating reciprocating lead screw 5 will drive the reciprocating block 6 to move back and forth. The reciprocating block 6 drives the rotating cylinder 9 to move through the clamping plate 10. The rotating cylinder 9 drives the connecting ring 19 to move. The connecting ring 19 drives the arc-shaped cleaning frame 3 to move through the second connecting rod 18. Since the arc-shaped cleaning frame 3 is in contact with the inner wall of the electrolytic cell 1, a friction cleaning effect on the inner wall of the electrolytic cell 1 will be formed; Moreover, the two clamping blocks 14 on both sides are not symmetrically arranged. That is, although the shapes of the two clamping blocks 14 are the same, the lower side of the clamping block 14 is a shape similar to a trapezoid. Among them, based on the Figure 6 direction, the front side of the left clamping block 14 is an inclined surface, and the rear side of the right clamping block 14 is an inclined surface. The directions of the two clamping blocks 14 on both sides are not the same. In the initial state, the lower ends of the two clamping blocks 14 are both located in the clamping grooves 8. That is, when the reciprocating lead screw 5 rotates clockwise, based on the Figure 5 and Figure 12From the perspective of [description missing in the original], the reciprocating lead screw 5 drives the rotating plate 41 to rotate clockwise. When the rotating plate 41 abuts against the auxiliary plate 42, it will drive the auxiliary plate 42 and the swing plate 40 to swing counterclockwise. The swing plate 40 will cause the third springs 43 on both sides to deform. In the initial state, the latch blocks 14 on both sides are located in the card slots 8. When the swing plate 40 swings counterclockwise, the side wall of the left latch block 14 abuts against the card slot 8, causing the latch block 14 to rotate counterclockwise around the rotating cylinder 9. And although the side wall of the right latch block 14 abuts against the card slot 8, under the action of the counterclockwise swinging swing plate 40, it will not drive the right latch block 14 to rotate (the above structure is similar to the ratchet structure in real life). The left latch block 14, under the action of the sleeve 13 and the rotating plate 11, drives the left limiting rod 20 to rotate counterclockwise. When the left limiting rod 20 abuts against the limiting plate 29, it will drive the left sliding plate 27 to rotate counterclockwise. Since the sliding plate 27 is slidably connected to the rotating cylinder 9, finally the rotating cylinder 9 will rotate counterclockwise. The rotating cylinder 9 will drive the two connecting rings 19 to rotate counterclockwise through the connecting plate 32 and the first spring 33. During this process, the front arc-shaped cleaning frame 3 will disconnect from the inner wall of the electrolytic cell 1. The arc-shaped cleaning frame 3 can abut against the inner wall of the bipolar plate (during the operation of the bipolar plate, certain precipitates and impurities will accumulate on the surface of the bipolar plate, resulting in the thickening of the bipolar plate. During the swinging process of the arc-shaped cleaning frame 3, when the arc-shaped cleaning frame 3 abuts against the thickened bipolar plate, it will clean the surface of the bipolar plate) until the rotating plate 41 disconnects from the auxiliary plate 42. During the above working process, the rear arc-shaped cleaning frame 3 always abuts against the inner wall of the electrolytic cell 1. Therefore, this arc-shaped cleaning frame 3 cannot rotate, and the corresponding first connecting plate 32 will compress the corresponding first spring 33. When the servo motor 4 changes the rotation direction, that is, when the reciprocating lead screw 5 swings counterclockwise, it will cause the rear arc-shaped cleaning frame 3 to disconnect from the inner wall of the electrolytic cell 1. The front arc-shaped cleaning frame 3 always abuts against the inner wall of the electrolytic cell 1, and the rear arc-shaped cleaning frame 3 abuts against the bipolar plate, forming a friction cleaning effect on the bipolar plate; As Figure 5 , a limiting component is installed in the deep groove 2. The limiting component includes a plurality of trapezoidal plates 7 fixedly installed at the bottom of the deep groove 2. Two moving rods 16 are slidably connected to the reciprocating block 6. Moving plates 15 are fixedly connected to the upper sides of the two moving rods 16. The moving plates 15 are commonly fixedly connected with two triangular plates 17. Two trapezoidal rings 22 are slidably connected to the outer side of the rotating cylinder 9. The two trapezoidal rings 22 are both fixedly connected to the sliding plate 27 through the third connecting rods 28; First, the trapezoidal plate 7 is located directly below the bipolar plate and is opposite to the bipolar plate in position. During the movement of the reciprocating block 6, when the reciprocating block 6 is about to move to the directly lower side of the bipolar plate, the moving rod 16 abuts against the trapezoidal plate 7. Under the action of the trapezoidal plate 7, the moving rod 16 will drive the moving plate 15 to move upward, and the moving plate 15 will drive the triangular plate 17 to move upward. When the triangular plate 17 abuts against the trapezoidal ring 22, the trapezoidal ring 22 will move towards the middle plate 25. The trapezoidal ring 22 drives the sliding plate 27 to move through the third connecting rod 28. While the sliding plate 27 compresses the connecting spring 26, it will drive the limiting plate 29 to move, and then the limiting rod 20 and the limiting plate 29 will be disconnected. That is, at this time, the rotating clamping block 14 will not drive the rotating cylinder 9 to rotate, and the arc-shaped cleaning frames 3 on both sides will return to their original positions, that is, both arc-shaped cleaning frames 3 abut against the inner wall of the electrolytic cell 1 until the moving rod 16 is disconnected from the trapezoidal plate 7, which will again cause two different situations to alternate: one arc-shaped cleaning frame 3 abuts against the inner wall of the electrolytic cell 1, the other arc-shaped cleaning frame 3 abuts against the side wall of the bipolar plate, or both arc-shaped cleaning frames 3 abut against the inner wall of the electrolytic cell 1; Therefore, in this case, by controlling the servo motor 4 to drive the reciprocating screw rod 5 to rotate periodically back and forth, two different situations will occur: one arc-shaped cleaning frame 3 abuts against the inner wall of the electrolytic cell 1, the other arc-shaped cleaning frame 3 abuts against the side wall of the bipolar plate, or both arc-shaped cleaning frames 3 abut against the inner wall of the electrolytic cell 1. Therefore, not only the inner wall of the electrolytic cell 1 but also the side wall of the bipolar plate can be cleaned, and the cleaning effect is good.

[0015] Such as Figure 9 、 Figure 10 、 Figure 11 In the arc-shaped cleaning frame 3, a knocking component is installed. The knocking component includes an arc-shaped plate 34 slidably installed in the arc-shaped cleaning frame 3. A square plate 36 is fixedly connected to the side wall of the arc-shaped plate 34. The square plate 36 slidably penetrates through the arc-shaped cleaning frame 3. A positioning plate 38 is fixedly connected to the outside of the square plate 36. A second spring 39 is fixedly connected between the positioning plate 38 and the arc-shaped cleaning frame 3. An intermediate ring 30 is fixedly connected to the outside of the rotating cylinder 9. A plurality of fixing blocks 31 are fixedly connected to the outside of the intermediate ring 30 in the circumferential direction. A plurality of protrusions are fixedly connected to the outside of the arc-shaped plate 34 in the circumferential direction. The side walls of the plurality of fixing blocks 31 and the square plate 36 are both set as smooth arcs; First, when one side of the arc-shaped cleaning frame 3 rotates, Figure 4Taking the rotation of the arc-shaped cleaning frame 3 on the left as an example based on the direction, the arc-shaped cleaning frame 3 on the right always abuts against the inner wall of the electrolytic cell 1. At this time, since the rotating cylinder 9 is in a rotating state, the rotating rotating cylinder 9 will drive the middle ring 30 and the fixed block 31 to rotate. When the fixed block 31 abuts against the square plate 36 on the right, it will drive the square plate 36 on the right to move relative to the arc-shaped cleaning frame 3 on the right. The arc-shaped plate 34 abuts against the inner wall of the electrolytic cell 1, which will form a knocking on the inner wall of the electrolytic cell 1, improving the cleaning work of the arc-shaped cleaning frame 3 on the inner wall of the electrolytic cell 1.

[0016] A plurality of pressure sensors 21 are fixedly connected between the arc-shaped cleaning frame 3 and the arc-shaped plate 34. A cavity is opened in the arc-shaped cleaning frame 3. Two openings 35 are opened on the side wall of the cavity. An electromagnetic control valve is fixedly installed in one of the openings 35, and an electromagnetic control valve is not installed in the other opening 35. Two control buttons 37 are symmetrically and fixedly connected to the upper side of the reciprocating block 6; First of all, the pressure sensor 21 is a device that can sense pressure and convert the pressure into an electrical signal and transmit it. Then, a fixed power supply is installed in the arc-shaped cleaning frame 3; the fixed power supply, the electromagnetic control valve, the control button 37, and the pressure sensor 21 form a closed circuit through wires. Among them, the electromagnetic control valve is a basic automation component for controlling fluids. Before working, first pour an appropriate amount of cleaning liquid into the cavity inside the arc-shaped cleaning frame 3. In the initial state, the opening 35 equipped with the electromagnetic control valve is in a closed state, and the opening 35 not equipped with the electromagnetic control valve is in an open state. The cleaning liquid in the cavity will flow out through the opening 35 not equipped with the electromagnetic control valve. When the arc-shaped cleaning frame 3 abuts against the inner wall of the electrolytic cell 1, the square plate 36 is located above the control button 37 and abuts against the control button 37, that is, the control button 37 is in a closed state. When the square plate 36 is disconnected from the control button 37, that is, the circuit inside the rotating arc-shaped cleaning frame 3 is in a closed state. During this process, if a large amount of substances accumulate on the outer side of the bipolar plate, when the arc-shaped cleaning frame 3 following the rotation of the rotating cylinder 9 abuts against the inner wall of the bipolar plate, under the obstruction of the substances on the outer side of the bipolar plate, it will cause relative rotation between the rotating arc-shaped cleaning frame 3 and the rotating cylinder 9. During this process, when the square plate 36 on the outer side of the rotating arc-shaped cleaning frame 3 abuts against the fixed block 31, under the obstruction of the fixed block 31, it will cause the square plate 36 to move relative to the arc-shaped cleaning frame 3. Since the square plate 36 and the arc-shaped plate 34 are fixedly connected, it will cause relative displacement between the arc-shaped plate 34 inside the rotating arc-shaped cleaning frame 3 and the arc-shaped cleaning frame 3, and then cause the pressure sensor 21 inside the rotating arc-shaped cleaning frame 3 to emit a corresponding electrical signal. The opening 35 equipped with the electromagnetic control valve is opened, and the greater the electrical signal emitted by the pressure sensor 21, the greater the flow rate at the opening 35 equipped with the electromagnetic control valve, and finally the outflow rate of the cleaning liquid can be automatically adjusted.

[0017] In the present invention, when electrolysis operation is required, an appropriate amount of electrolyte (i.e., wastewater) is introduced into the electrolytic cell 1 through the lower pipeline, and then the electrode plates and bipolar plates on both sides are energized. After energization, an oxidation reaction occurs at the anode under the action of an external electric field, and a reduction reaction occurs at the cathode. The anode loses electrons and undergoes an oxidation reaction, while the cathode gains electrons and undergoes a reduction reaction. Harmful substances are removed on the anode and cathode respectively. In addition, during the electrolysis process, the pH value of the wastewater changes, forming precipitates to further purify the wastewater. The above are all prior arts and will not be elaborated further; In the initial state, two arc-shaped cleaning frames 3 are located between the electrolytic cell 1 and the bipolar plate, and the two arc-shaped cleaning frames 3 are in contact with the inner wall of the electrolytic cell 1. When the inner wall of the electrolytic cell 1 needs to be cleaned, the servo motor 4 is started. The servo motor 4 drives the reciprocating lead screw 5 to rotate. Since the reciprocating block 6 is slidably connected to the deep groove 2 on the left and right, the rotating reciprocating lead screw 5 will drive the reciprocating block 6 to move back and forth. The reciprocating block 6 drives the rotating cylinder 9 to move through the clamping plate 10. The rotating cylinder 9 drives the connecting ring 19 to move. The connecting ring 19 drives the arc-shaped cleaning frame 3 to move through the second connecting rod 18. Since the arc-shaped cleaning frame 3 is in contact with the inner wall of the electrolytic cell 1, a friction cleaning effect on the inner wall of the electrolytic cell 1 will be formed; When the reciprocating lead screw 5 rotates clockwise, Figure 5 and Figure 12From the perspective of [description missing in the original Chinese], the reciprocating screw rod 5 drives the rotating plate 41 to rotate clockwise. When the rotating plate 41 abuts against the auxiliary plate 42, it will drive the auxiliary plate 42 and the swing plate 40 to swing counterclockwise. The swing plate 40 will cause the third springs 43 on both sides to deform. In the initial state, the clamping blocks 14 on both sides are located in the clamping grooves 8. When the swing plate 40 swings counterclockwise, the side wall of the left clamping block 14 abuts against the clamping groove 8, which will cause the clamping block 14 to rotate counterclockwise around the rotating cylinder 9. And although the side wall of the right clamping block 14 abuts against the clamping groove 8, under the action of the swing plate 40 swinging counterclockwise, it will not drive the right clamping block 14 to rotate (the above structure is similar to the ratchet structure in real life). The clamping block 14 drives the left limiting rod 20 to rotate counterclockwise under the action of the sleeve 13 and the rotating plate 11. When the left limiting rod 20 abuts against the limiting plate 29, it will drive the left sliding plate 27 to rotate counterclockwise. Since the sliding plate 27 is slidably connected to the rotating cylinder 9, finally the rotating cylinder 9 will rotate counterclockwise. The rotating cylinder 9 will drive the two connecting rings 19 to rotate counterclockwise through the connecting plate 32 and the first spring 33. During this process, the front arc-shaped cleaning frame 3 will be disconnected from the inner wall of the electrolytic cell 1, and the arc-shaped cleaning frame 3 can abut against the inner wall of the bipolar plate (during the operation of the bipolar plate, certain precipitates and impurities will accumulate on the surface of the bipolar plate, which will cause the bipolar plate to thicken. During the swinging process of the arc-shaped cleaning frame 3, when the arc-shaped cleaning frame 3 abuts against the thickened bipolar plate, it will clean the surface of the bipolar plate) until the rotating plate 41 is disconnected from the auxiliary plate 42. During the above working process, the rear arc-shaped cleaning frame 3 always abuts against the inner wall of the electrolytic cell 1. Therefore, this arc-shaped cleaning frame 3 cannot rotate, and it will cause the corresponding first connecting plate 32 to compress the corresponding first spring 33. When the servo motor 4 changes the rotation direction, that is, when the reciprocating screw rod 5 swings counterclockwise, it will cause the rear arc-shaped cleaning frame 3 to be disconnected from the inner wall of the electrolytic cell 1, the front arc-shaped cleaning frame 3 always abuts against the inner wall of the electrolytic cell 1, and the rear arc-shaped cleaning frame 3 abuts against the bipolar plate, forming a friction cleaning effect on the bipolar plate; During the movement of the reciprocating block 6, when the reciprocating block 6 is about to move to the directly lower side of the bipolar plate, the moving rod 16 abuts against the trapezoidal plate 7. Under the action of the trapezoidal plate 7, the moving rod 16 will drive the moving plate 15 to move upward, the moving plate 15 will drive the triangular plate 17 to move upward, the triangular plate 17 abuts against the trapezoidal ring 22, which will cause the trapezoidal ring 22 to move towards the middle plate 25. The trapezoidal ring 22 drives the sliding plate 27 to move through the third connecting rod 28. While the sliding plate 27 compresses the connecting spring 26, it will drive the limiting plate 29 to move, thereby causing the limiting rod 20 and the limiting plate 29 to disconnect. That is, at this time, the rotating clamping block 14 will not drive the rotating cylinder 9 to rotate, and the arc-shaped cleaning frames 3 on both sides return to their original positions, that is, both arc-shaped cleaning frames 3 abut against the inner wall of the electrolytic cell 1 until the moving rod 16 and the trapezoidal plate 7 are disconnected, which will again cause two different situations to alternate: one arc-shaped cleaning frame 3 abuts against the inner wall of the electrolytic cell 1, the other arc-shaped cleaning frame 3 abuts against the side wall of the bipolar plate, or both arc-shaped cleaning frames 3 abut against the inner wall of the electrolytic cell 1; When the arc-shaped cleaning frame 3 on one side rotates, taking Figure 4 the direction as the basis, taking the rotation of the left arc-shaped cleaning frame 3 as an example for illustration, the right arc-shaped cleaning frame 3 always abuts against the inner wall of the electrolytic cell 1. At this time, since the rotating cylinder 9 is in a rotating state, the rotating rotating cylinder 9 will drive the middle ring 30 and the fixed block 31 to rotate. When the fixed block 31 abuts against the right square plate 36, it will drive the right square plate 36 to move relative to the right arc-shaped cleaning frame 3. The arc-shaped plate 34 abuts against the inner wall of the electrolytic cell 1, which will form a knock on the inner wall of the electrolytic cell 1 and improve the cleaning work of the arc-shaped cleaning frame 3 on the inner wall of the electrolytic cell 1; Secondly, two openings 35 are provided on the side wall of the cavity. An electromagnetic control valve is fixedly installed in one of the openings 35, denoted as the opening 35 equipped with the electromagnetic control valve, and no electromagnetic control valve is installed in the other opening 35, denoted as the opening 35 without the electromagnetic control valve. Then, a fixed power source is installed inside the arc-shaped cleaning frame 3; the fixed power source, the electromagnetic control valve, the control button 37, and the pressure sensor 21 form a closed circuit through wires. Among them, the electromagnetic control valve is a basic automation component for controlling fluids. Before working, an appropriate amount of cleaning liquid is poured into the cavity inside the arc-shaped cleaning frame 3. In the initial state, the opening 35 equipped with the electromagnetic control valve is in a closed state, and the opening 35 without the electromagnetic control valve is in an open state. The cleaning liquid in the cavity will flow out through the opening 35 without the electromagnetic control valve. When the arc-shaped cleaning frame 3 abuts against the inner wall of the electrolytic cell 1, the square plate 36 is located above the control button 37 and abuts against the control button 37, that is, the control button 37 is in a closed state. When the square plate 36 is disconnected from the control button 37, that is, the circuit inside the rotating arc-shaped cleaning frame 3 is in a closed state. During this process, if a large amount of substances accumulate on the outer side of the bipolar plate, when the arc-shaped cleaning frame 3 following the rotating cylinder 9 abuts against the inner wall of the bipolar plate, due to the obstruction of the substances on the outer side of the bipolar plate, relative rotation will occur between the rotating arc-shaped cleaning frame 3 and the rotating cylinder 9. During this process, when the square plate 36 on the outer side of the rotating arc-shaped cleaning frame 3 abuts against the fixed block 31, due to the obstruction of the fixed block 31, the square plate 36 will move relative to the arc-shaped cleaning frame 3. Since the square plate 36 and the arc-shaped plate 34 are fixedly connected, relative displacement will occur between the arc-shaped plate 34 inside the rotating arc-shaped cleaning frame 3 and the arc-shaped cleaning frame 3, and then the pressure sensor 21 inside the rotating arc-shaped cleaning frame 3 will emit a corresponding electrical signal. The opening 35 equipped with the electromagnetic control valve is opened, and the greater the electrical signal emitted by the pressure sensor 21, the greater the flow rate at the opening 35 equipped with the electromagnetic control valve, and finally the outflow speed of the cleaning liquid can be automatically adjusted.
