Continuous production equipment for ion exchange membrane for vanadium battery

Abstract

This application discloses a continuous production equipment for ion exchange membranes used in vanadium batteries, relating to the field of ion exchange membranes. It includes an operating table and a clamping mechanism at the top of the operating table for holding the ion exchange membrane. A motor is provided on one side of the clamping mechanism to provide driving force. Inside the clamping mechanism is a cutting mechanism for cutting the ion exchange membrane while it is being held. This application achieves intermittent stable clamping by driving the clamping block to close, which is fixed in two directions. This is linked to the rotation of a reciprocating screw, and with the assistance of a sensor, the water jet nozzle performs non-contact cutting of the ion exchange membrane, eliminating edge burrs from mechanical blades and dimensional deviations caused by tool wear. Since the cutting is performed while the ion exchange membrane is completely clamped and fixed, vibration or displacement during cutting is avoided, ensuring cutting dimensional accuracy and improving the production efficiency of the ion exchange membrane.

[0015] Preferably, a timing pulley is fixed at one end of the rotating shaft two between the spur gear three and the baffle one, and a timing pulley two is fixed at one end of the rotating shaft one near the baffle one. A toothed belt is fitted on the outer side of the timing pulley one and the timing pulley two.

[0016] By adopting the above technical solution, synchronous pulley one and synchronous pulley two are connected by a toothed belt drive to realize synchronous linkage and power transmission between rotating shaft one and rotating shaft two.

[0017] Preferably, the lubrication mechanism includes an air bladder disposed at the top of the first clamping block and a pressing block movably disposed on one side of the air bladder. A fixing plate fixed to the top of the first clamping block is fixed on one side of the air bladder. The bottom end of the pressing block is fixed to the top of the second clamping block. An oil delivery pipe is fixedly disposed through the bottom end of the air bladder and communicates with one side of the top of the first clamping block.

[0018] By adopting the above technical solution, the lubrication mechanism consists of an air bladder fixed to the top of the clamping block one on a fixed plate, a pressing block that moves with the clamping block two, and an oil supply pipe connecting the air bladder and the inside of the clamping block one.

Motor two drives one of the conveyor rollers two to rotate, and the two conveyor rollers two rotate in opposite directions through the meshing spur gear one at their ends, so that the conveyed ion exchange membrane passes through the feeding roller and then passes around conveyor roller one and conveyor roller two to be conveyed to the clamping mechanism.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. By starting the motor, the turntable is driven to rotate, causing the slider to slide within the irregular groove. This, in turn, causes the rotating block to rotate around the fixed shaft, which in turn drives the connecting rod and transmission plate to move. This drives the clamping block to close, achieving intermittent and stable clamping. Simultaneously, the rotating shaft drives the reciprocating screw to rotate synchronously through the synchronous pulley, toothed belt, and synchronous pulley. With the help of a sensor, the water jet nozzle cuts the clamped ion exchange membrane. This device uses water jets for non-contact cutting, eliminating edge burrs and dimensional deviations caused by tool wear from mechanical blades. Furthermore, since the cutting is performed while the ion exchange membrane is completely clamped and fixed, vibration or displacement during cutting is avoided, ensuring cutting dimensional accuracy and improving the production efficiency of ion exchange membranes.

[0026] 2. The intermittent closing action of the clamping mechanism drives the pressing block to squeeze the air bladder, so that the lubricating oil can be automatically delivered to the surface of the reciprocating screw in a timely and quantitative manner, realizing the self-lubrication of the equipment and reducing maintenance requirements. During the cutting process, the rectangular groove on the clamping block and the sewage discharge groove form a closed cutting area, so that the generated sewage is collected and flows into the filter box through the sewage discharge hole and sewage discharge pipe for efficient filtration. After being pumped back by the high-pressure pump, it is recycled. This device facilitates the cleaning of the cutting environment and the maintenance of the equipment, reduces production costs, and is conducive to the needs of green and sustainable modern production.

The clamping mechanism 2 is equipped with a cutting mechanism 3 inside, which is used to cut the ion exchange membrane when the clamping mechanism 2 clamps the ion exchange membrane. A motor 5 is provided on one side of the clamping mechanism 2 to provide driving force for the clamping mechanism 2. A lubrication mechanism 4 is provided at the top of the clamping mechanism 2 to lubricate the cutting mechanism 3. A baffle 8 and a baffle 9 are fixed on both sides of the top of the operating table 1, respectively. A feeding roller 18 and a conveying roller 19 are rotatably arranged on one end of the opposite side of the baffle 8 and the baffle 9. The conveying roller 19 is located at an oblique position above the feeding roller 18.

[0032] A conveyor roller 20 is symmetrically and rotatably installed on opposite sides of baffle 1 8 and baffle 2 9. The ends of the two conveyor rollers 20 near baffle 1 8 pass through the upper side of baffle 1 8. A spur gear 24 is fixedly sleeved on the outer side of the two conveyor rollers 20. The teeth on the surfaces of the two spur gears 24 mesh, so that when one conveyor roller 20 rotates, it drives the other conveyor roller 20 to rotate in the opposite direction. A motor 2 6 is fixedly installed on one of the conveyor rollers 20 of baffle 1 8. The drive end of the motor 2 6 is fixed to the outer side of the one conveyor roller 20 of baffle 1 8. The motor 5 is fixed in the middle of baffle 1 8. The ion exchange membrane passes sequentially around the feeding roller 18, the conveyor roller 1 9 and the two conveyor rollers 20 and inside the clamping mechanism 2.

[0033] Before use, the device needs to be embedded as a whole into the vanadium battery ion exchange membrane production line, located between the end of production and the packaging process; fix the operating table 1 to the ground, connect the feeding roller 18 to the production line unwinding device, fix the second conveyor roller 20 to the output end of the second motor 6, install the clamping mechanism 2 between the first baffle 8 and the second baffle 9, install the cutting mechanism 3 inside the clamping mechanism 2, fix the lubrication mechanism 4 on the clamping mechanism 2 and connect it to the cutting mechanism 3, fix the high pressure pump 7 to the top of the clamping mechanism 2 and connect it to the filter box 13 through the water pumping pipe 15.

[0034] Two conveyor belts 10 are installed on one side of the top of the operating platform 1, near the first baffle 8 and the second baffle 9. Both ends of the conveyor belts 10 are fixed with the third baffle 17. The bottom end of the third baffle 17 is fixed to the top of the operating platform 1. The top of the operating platform 1 has a discharge port 11 on the side of the conveyor belts 10 away from the first baffle 8 and the second baffle 9. The bottom of the operating platform 1 has a collection box 12 and a filter box 13. The collection box 12 is located directly below the discharge port 11. The collection box 12 is used to collect the ion exchange membrane after cutting. The filter box 13 is equipped with a Pentair RO+EDI system. This system supports customized flow rates from 0.25 to 50 T / h and adopts "RO+EDI+polishing mixed bed" technology. The resistivity of the effluent can reach 18.25 MΩ·cm, which meets the ASTM D1193 ultrapure water standard. It is suitable for waterjet cutting, electronic chip cleaning and other scenarios, and is used for recycling and filtering used pure water.

[0035] In use, the ion exchange membrane is introduced from the feeding roller 18, passes through the first conveyor roller 19 and enters between the two second conveyor rollers 20. The second motor 6 drives the second conveyor rollers 20 to intermittently transport the ion exchange membrane to the clamping mechanism 2. The first motor 5 drives the clamping mechanism 2 to clamp the ion exchange membrane. At the same time, the sensor 21 triggers a signal to start the high-pressure pump 7 to transport the pure water in the filter box 13 to the cutting mechanism 3 through the water supply pipe 14. The clamping mechanism 2 operates in conjunction with the cutting mechanism 3 to complete reciprocating cutting. The wastewater generated during cutting flows into the filter box 13 through the sewage pipe 23. After being filtered by the filter box 13, it is recycled. The cut ion exchange membrane is transported to the discharge port 11 by the conveyor belt 10 and enters the collection box 12 to complete continuous production.

The end of slider 202 near turntable 201 slides in irregular groove 209. A rotating shaft 212 is fixedly installed through the middle of circular hole 217. One end of rotating shaft 212 passes through the upper end of baffle 8. The end of rotating shaft 212 away from baffle 8 is fixed to the upper end of baffle 9. The end of rotating shaft 212 located outside baffle 8 is fixed to the output end of motor 5. A rotating block 203 is rotatably fitted on the end of slider 202 away from turntable 201. The rotating block 203 consists of two mirrored rectangles and a circular shaft. The shape of rotating block 203 (as shown) Figure 8 (As shown).

[0037] The rotating block 203 has two circular holes, 218 and 220, respectively, at its two ends. A circular hole 219 is located in the middle of the rotating block 203. The rotating block 203 is rotatably mounted on the end of the slider 202 away from the turntable 201 via the circular hole 218. A fixed shaft 213 is movably inserted through the circular hole 219. Both ends of the fixed shaft 213 are fixed to the opposite sides of the baffle 8 and baffle 9, respectively. The fixed shaft 213 is located diagonally below the rotating shaft 212. Rotating block 203 rotates around fixed shaft 213. A connecting rod 204 is rotatably provided at the end of rotating block 203 away from slider 202. Circular holes 221 are opened at both ends of connecting rod 204. A rotating rod 214 is rotatably provided through the circular hole 221 at the end of connecting rod 204 near rotating block 203. The end of rotating rod 214 away from connecting rod 204 is rotatably provided through circular hole 220. A transmission plate 205 is rotatably provided at the end of connecting rod 204 away from rotating block 203.

[0038] A circular hole 223 is provided in the middle of the transmission plate 205, and circular holes 222 are provided at both ends of the transmission plate 205. A rotating rod 215 is rotatably inserted through the circular hole 221 at the end of the connecting rod 204 away from the rotating block 203. The end of the rotating rod 215 away from the connecting rod 204 is rotatably inserted through the circular hole 223. A transmission rod 206 is fixedly inserted through the interior of the circular hole 222. A clamping block 208 is fixedly fitted at the end of the transmission rod 206 away from the transmission plate 205. The two ends of 08 are provided with circular holes 10 228. The end of the transmission rod 206 away from the transmission plate 205 is fixedly inserted through the circular hole 10 228. The middle part of the transmission rod 206 is movably fitted with a limiting block 210. The middle part of the limiting block 210 is provided with a circular hole 8 224. The middle part of the transmission rod 206 is movably inserted through the circular hole 8 224. The end of the transmission rod 206 near the clamping block 208 is movably fitted with a clamping block 1 207. The top of the clamping block 1 207 near the side of the baffle 1 8 is provided with a leakage hole 211.

[0039] When in use, the device drives the rotating shaft 212 to rotate by turning on the motor 5, which in turn drives the turntable 201 to rotate synchronously with the rotating shaft 212. This causes the slider 202 to slide in the irregular groove 209 of the turntable 201, which in turn causes the rotating block 203 to rotate around the fixed shaft 213. This causes the rotating rod 214 to push the connecting rod 204 to move, which in turn drives the rotating rod 215 to drive the transmission plate 205 to move along the axis of the transmission rod 206. This causes the clamping block 208 to move toward the clamping block 207, and at the same time, it causes the clamping plate 226 to move toward the clamping block 207, thus stably clamping the ion exchange membrane. At this time, the spring 227 is in a compressed state.

[0040] One side of clamping block 207 is fixed to the side of baffle 29 facing baffle 8. Both ends of clamping block 207 are provided with circular holes 9 225. The end of transmission rod 206 near clamping block 208 is movably inserted through circular hole 9 225. Clamping block 207 is located between circular hole 8 224 and clamping block 208.

A sewage hole 231 is provided in the middle of the inner bottom surface of sewage trough 230. Sewage trough 230 and sewage hole 231 are used to collect sewage generated during cutting. A rectangular groove 229 is provided in the middle of the side of clamping block 207 opposite to rectangular groove 1 216. A clamping plate 226 is slidably arranged inside the side of clamping block 208 near clamping block 207. The shape of clamping plate 226 is adapted to the internal shape of clamping block 208.

[0041] When the slider 202 slides to a certain position in the irregular groove 209 of the turntable 201, it drives the rotating block 203 to rotate in the opposite direction around the fixed shaft 213, which in turn drives the connecting rod 204 and the transmission rod 206 to move in the opposite direction, thereby causing the clamping block 208 to separate from the clamping block 207. At this time, the spring 227 rebounds and drives the clamping plate 226 to reset, preparing for the next clamping.

[0042] Multiple springs 227 are fixed on the side of clamping plate 226 near clamping block 208 (the formula for calculating the elastic force of spring 227 is F=kx, where F represents the elastic force of spring 227, k represents the spring constant, and x represents the compression of spring 227). The two ends of spring 227 are fixed to the inner wall of clamping block 208 and the side of clamping plate 226 facing clamping block 208, respectively. A baffle 4 22 is fixed on the side of clamping block 1 207 near baffle 1 8. The side of clamping block 1 207 near baffle 4 22 is fixed to the surface of baffle 4 22. The bottom end of baffle 4 22 is fixed to the top end of operating table 1. Baffle 4 22 is located between baffle 1 8 and baffle 2 9. The opposite sides of the two limiting blocks 210 are fixed to the opposite sides of baffle 2 9 and baffle 4 22, respectively.

[0043] The closing action of clamping block 1 207 and clamping block 208 forms a closed cutting area between rectangular groove 1 216 and sewage discharge groove 230. After the cutting mechanism 3 completes the cutting, the sewage flows into the filter box 13 through the sewage discharge hole 231 and sewage discharge pipe 23, and is recycled through the Pentair RO+EDI system of the filter box 13.

[0044] Reference Figure 12 The cutting mechanism 3 includes a reciprocating screw 301 that rotatably passes through both sides of the clamping block 207 and a water jet nozzle 303 threaded onto the surface of the reciprocating screw 301. One end of the reciprocating screw 301 rotatably passes through the baffle 22 and one side of the clamping block 207. The two ends of the reciprocating screw 301 are respectively rotatably disposed on the inner wall of the clamping block 207 and the side of the baffle 8 facing the baffle 9. A shaped block 302 is sleeved on the surface of the reciprocating screw 301. The upper end of the shaped block 302 has an opening that is connected to the reciprocating screw 301. The reciprocating screw 301 is adapted to the threaded groove, and the reciprocating screw 301 passes through the threaded groove. The irregular block 302 is located inside the rectangular groove 216 and diagonally above the sewage tank 230, and does not affect the sewage tank 230 from collecting sewage. The shape of the irregular block 302 is adapted to the shape of the rectangular groove 216. The irregular block 302 slides inside the rectangular groove 216. The water jet nozzle 303 is fixedly installed through the lower end of the irregular block 302. The water jet nozzle 303 is used to cut the ion exchange membrane.

[0045] A spur gear 2 304 is fixedly sleeved at one end of the reciprocating screw 301 located outside the baffle 4 22. A spur gear 305 is provided on one side of the spur gear 2 304. The teeth on the surface of the spur gear 305 mesh with the teeth on the surface of the spur gear 2 304. The center points of the spur gear 2 304 and the spur gear 305 are on the same horizontal line. The number of teeth on the surface of the spur gear 305 is four times the number of teeth on the surface of the spur gear 2 304. This allows the spur gear 305 to rotate one revolution, which in turn drives the spur gear 2 304 to rotate four revolutions. A rotating shaft 2 309 is fixedly installed through the middle of the spur gear 305. The two ends of the rotating shaft 2 309 are respectively rotatably installed on the opposite side of the baffle 4 22 and the baffle 1 8. A transmission component is sleeved at the end of the rotating shaft 2 309 located between the spur gear 305 and the baffle 1 8.

[0046] The transmission assembly includes a first synchronous pulley 306, a second synchronous pulley 307, and a toothed belt 308. The first synchronous pulley 306 is fixedly sleeved on one end of the second rotating shaft 309 located between the third spur gear 305 and the first baffle 8. The middle part of the second synchronous pulley 307 is fixedly sleeved on one end of the first rotating shaft 212 near the first baffle 8, and the first synchronous pulley 306 and the second synchronous pulley 307 are on the same plane. The toothed belt 308 passes around the outer sides of the first synchronous pulley 306 and the second synchronous pulley 307 in sequence. The teeth of the toothed belt 308 mesh with the tooth grooves on the surfaces of the first synchronous pulley 306 and the second synchronous pulley 307, thereby causing the second rotating shaft 309 to rotate synchronously when the first rotating shaft 212 rotates.

[0047] In use, by turning on motor 5 to drive rotating shaft 212 to rotate, synchronous pulley 307 rotates synchronously with rotating shaft 212, driving toothed belt 308 to drive synchronous pulley 306 to rotate, thereby causing rotating shaft 309 to be linked with spur gear 305. Through the 4:1 gear ratio of spur gear 305 to spur gear 304, the reciprocating screw 301 obtains a speed four times that of rotating shaft 212, driving the irregular block 302 to slide along the threaded groove in rectangular groove 216, thereby causing water jet nozzle 303 to move back and forth along a set path to cut the ion exchange membrane in the clamped state.

[0048] Reference Figure 13 The lubrication mechanism 4 includes an airbag 401 disposed at the top of clamping block 207 and a pressing block 402 movably disposed on one side of the airbag 401. The airbag 401 is made of food-grade silicone and has elastic recovery properties, ensuring that the pressing block 402 automatically returns to its original position after being squeezed, maintaining the continuous supply of lubricating oil. A fixing plate 403 is fixedly disposed on the side of the airbag 401 away from the pressing block 402. The bottom end of the fixing plate 403 is fixed to the top end of clamping block 207, and the bottom end of the pressing block 402 is fixed to the top end of clamping block 208 near the baffle 8. The shape of the pressing block 402 is as follows (e.g., Figure 13 As shown), the pressing block 402 is used to squeeze the airbag 401 when the clamping block 208 is close to the clamping block 207. An oil supply pipe 404 is fixedly provided in the middle of the bottom end of the airbag 401. The end of the oil supply pipe 404 away from the airbag 401 is fixedly connected to the leakage hole 211, so that the lubricating oil inside the airbag 401 is transmitted to the surface of the reciprocating screw 301 to lubricate the reciprocating screw 301.

[0049] By opening the clamping mechanism 2, the clamping block 208 closes to the clamping block 207, which drives the pressing block 402 to squeeze the air bag 401. The lubricating oil inside the air bag 401 is then transported to the leakage hole 211 through the oil supply pipe 404, and the lubricating oil continues to flow to the surface of the reciprocating screw 301 to form an oil film. After being squeezed, the air bag 401 automatically recovers due to its own elasticity, maintaining the continuous oil supply capacity.

[0050] Reference Figures 1-5 A high-pressure pump 7 is fixedly installed at the top of the clamping block 207 to pump water from the inside of the filter box 13 to the water jet nozzle 303. The high-pressure pump 7 is a DC30 series micro DC pump from Shenzhen Zhongke Century Technology Co., Ltd. The inlet of the high-pressure pump 7 is fixedly connected to a water pumping pipe 15. The end of the water pumping pipe 15 away from the high-pressure pump 7 is fixedly connected to the lower end of the filter box 13. Multiple fixing blocks 16 are fixedly installed on one side of the filter box 13, the operating table 1, and the baffle 3 17. The fixing blocks 16 are used to fix the water pumping pipe 15. The outlet of the high-pressure pump 7 is fixedly connected to a water delivery pipe 14. The end of the water delivery pipe 14 away from the high-pressure pump 7 is fixedly connected to the water jet nozzle 303.

[0051] A sensor 21 is installed at the top center of clamp 207 near the high-pressure pump 7. The sensor 21 is an LT18 series clamp position sensor manufactured by Shanghai Lanbao Sensor Technology Co., Ltd., model LT18SN02DPOA-E2. It has anti-magnetic interference function, short circuit and overload protection, and a detection distance of 2mm. It is suitable for accurate detection of clamp position. The sensor 21 is connected to the high-pressure pump 7 and PLC control module through a signal line. It is used to detect whether the clamp is closed in place and to feed back to the control system, triggering the high-pressure pump 7 and the water jet nozzle 303 to spray water, ensuring cutting accuracy and equipment safety. A drain pipe 23 is fixedly installed at the bottom center of clamp 207 at the drain hole 231. The end of the drain pipe 23 away from clamp 207 is fixed to the top of the filter box 13. It is used to guide sewage into the filter box 13 for filtration, which is convenient for secondary use.

[0052] The clamping block 208 closes and triggers the sensor 21 to detect the clamping position signal, and sends a command to the high-pressure pump 7. The high-pressure pump 7 is turned on so that the water pumping pipe 15 draws pure water from the filter box 13 and delivers it to the water jet nozzle 303 through the water delivery pipe 14 to form a high-pressure water flow. The water jet nozzle 303 is driven by the reciprocating screw 301 to move back and forth along the rectangular groove 216 to perform cutting. The wastewater generated by cutting flows into the drain pipe 23 through the drain hole 231, and then enters the filter box 13 for internal circulation and filtration.

[0053] The implementation principle of the continuous production equipment for vanadium battery ion exchange membranes in this application embodiment is as follows: The device introduces the ion exchange membrane through the feeding roller 18, which then enters between two conveyor rollers 20 via the first conveyor roller 19. The second motor 6 drives the second conveyor roller 20 to intermittently transport the ion exchange membrane to the clamping mechanism 2. The first motor 5 drives the turntable 201 to rotate, causing the slider 202 to slide within the irregular groove 209, making the rotating block 203 rotate around the fixed shaft 213. The connecting rod 204 drives the transmission plate 205 to drive the transmission rod 20. 6. Move the clamping block 208 to close the clamping block 207. The clamping plate 226 stably clamps the ion exchange membrane under the action of the spring 227. At the same time, the sensor 21 triggers a signal to make the high-pressure pump 7 draw pure water from the filter box 13 and deliver it to the water jet nozzle 303 through the water delivery pipe 14. The water jet nozzle 303 is driven by the reciprocating screw 301 to reciprocate cutting along the rectangular groove 216. The sewage flows into the filter box 13 for circulation and purification through the drain hole 231 and the drain pipe 23. After cutting, the ion exchange membrane is sent to the discharge port 11 by the conveyor belt 10 and enters the collection box 12.
