[0063] An intelligent control method for an electric desalting black water oil-water scum separation device comprises the following steps:

[0064] S1. When separating oil and water, the personnel only need to use the intelligent controller to start the air pump and the reverse osmosis device. The reverse osmosis device will introduce the water source into the L-shaped connecting pipe through the suction pump, and the L-shaped connecting pipe will transmit the water source to the reverse osmosis device. The oil and water can be separated by the reverse osmosis membrane in the reverse osmosis device. The oil will be discharged to the outside through the reverse osmosis device, and the water will provide a discharge hole to enter the electrolyzer again. When the air pump is restarted, the external gas will be introduced into the air pipe, and then the air pipe will be transmitted to the two shunt pipes. The two shunt pipes will divert the gas in the air pipe and transmit it to the bottom inner wall of the electrolyzer, and then cooperate with the rotation of the impeller to make the transmitted gas produce bubbles. The bubbles will float upward in the black water, and the impurities in the black water and oil and water will be taken out during the floating process, so that the impurities float above the oil layer, and then through the two skimming fans in the skimming cleaning mechanism The leaves process the scum, and the skimmed impurities will fall into the L-shaped storage port. The impurities will then enter the first storage box through the L-shaped storage port to achieve final collection. When separating the black water, the personnel use the intelligent controller to start the cathode and anode, and the black water passes through the electrolytic cell. During the electrolysis process, the salt in the black water is decomposed into hydroxide and hydrogen. At the same time, oil, water, scum and other components are also electrolyzed and separated. The conductivity sensor, flow meter and pH sensor are used to monitor the working parameters in the electrolytic cell in real time, such as brine concentration, current, voltage, etc. If the brine concentration is detected to drop, the control system may increase the current or voltage to improve the desalination efficiency. According to the working status and processing requirements of the device, the power supply output voltage, current and other parameters are automatically adjusted to achieve real-time control of the device. The intelligent controller can optimize the operation effect of the device, improve the processing efficiency, reduce energy consumption and simplify the operation;

[0065] S2. When pushing and collecting the decomposed hydroxide, the personnel only need to use the intelligent controller to start the first motor, and the output shaft of the first motor will immediately drive one of the first rotating rods to rotate, and one of the first rotating rods will drive one of the first pulleys and one of the third gears on the surface to rotate, and one of the third gears will drive the first toothed belt on the surface to rotate, so that the first toothed belt transmission drives another third gear to drive the first rotating rod to rotate, so that the two first rotating rods can rotate synchronously, so that the two first rotating rods can drive the two skimming blades on the surface to flip and skim the floating scum on the upper side of the oil layer into the L-shaped receiving port to achieve separation. One of the first pulleys will rotate when it rotates. The first belt on the surface is driven to rotate, and the first belt will drive another first pulley inside to rotate, so that the first pulley drives the first gear to rotate, and the first gear will drive the two second gears on the surface to rotate, and the two second gears will synchronously drive the two screws to rotate, and the rotation of the two screws will drive the four nuts on the surface to approach and move each other, and the nuts will drive the four moving push plates to slide on the lower inner wall of the electrolytic cell while moving, so that the four moving push plates push the hydroxide produced by electrolysis on the lower inner wall of the electrolytic cell until the four moving push plates are close, so that the hydroxide will fall into the square frame through the conical groove, and then the hydroxide and the liquid will be separated again through the cooperation of the components in the screening mechanism;

[0066] S3. Hydroxide will fall into the concave screen in the square frame through the opening and closing of the intelligent valve. Since the concave screen is concave in shape and the inner wall of the concave screen is semicircular in shape, the hydroxide in the concave screen will be cleaned out when the plastic spiral transmission blade rotates, so that the hydroxide enters the first threaded sleeve through the second threaded sleeve to achieve final collection. In order to prevent the hydroxide from clogging the concave screen, the personnel will use the intelligent controller to start the second motor, and the output shaft of the second motor will immediately drive the first mounting block to rotate. When the first mounting block rotates, it will drive one of the second pulleys on the surface to rotate, and then one of the second pulleys will drive the second belt on the surface to rotate, and the second belt will drive another second pulley on the inner wall of the circle to rotate, so that the other second pulley drives the third bevel gear to rotate through the third mounting block, and then the third bevel gear will drive the fourth bevel gear on the circumferential surface to rotate, and the fourth bevel gear will drive the The four rotating rods rotate, and then the fourth rotating rod drives the fifth gear and the two second convex wheels on the surface to rotate, so that the two second convex wheels will lift up the two concave arc blocks during the rotation, so that the two concave arc blocks will move up and down repeatedly, and the movement of the two concave arc blocks will drive the concave screen to move. When the concave screen is downward, the concave screen will squeeze four of the springs at the bottom to shrink it. The springs themselves are elastic. When the second convex wheel does not lift up the concave arc blocks, the elasticity of the springs will be reset. Repeated shaking of the concave screen will screen out the blocked hydroxides, and the screened hydroxides will fall on the top of the vibrating net, and then be discharged into the second storage box through the opening of the square frame to achieve final collection, and the moisture contained in the hydroxide is collected by filter cotton, and personnel are required to replace the filter cotton regularly. The second storage box itself has two collection slots. The top collection slot is used to collect liquids, and the front collection slot is used to collect hydroxides.

[0067] Compared with the prior art, the present invention has the following beneficial effects:

[0068] 1. In the process of preliminary separation of oil and water, the operator starts the air pump and reverse osmosis device through the intelligent controller, so that the oil-water mixture sucked by the suction pump is transmitted to the reverse osmosis device. The reverse osmosis membrane can separate oil and water. Due to the size and polarity of oil molecules, they cannot pass through the membrane, but water molecules can. The oil molecules will be discharged to the threaded interface, and the water molecules will be discharged to the discharge hole through the device, re-enter the separation box, and finally enter the electrolytic cell. At the same time, when the air pump is started, external gas will be introduced and transmitted to the inner wall of the bottom of the electrolytic cell through the shunt pipe. In coordination with the rotation of the impeller, the gas will be broken into bubbles. These bubbles will float up and bring impurities in the liquid to the top of the oil layer to form scum. The components in the skimming and cleaning mechanism will skim the scum and collect it to the L-shaped receiving port, and finally enter the first receiving box. For the separation of black water, the operator uses intelligent The controller starts the cathode and anode, and the black water passes through the electrolytic cell. During the electrolysis process, the salt is decomposed into hydroxide and hydrogen, and the oil, water and scum are also separated by electrolysis. The collection of hydroxide is achieved by starting the first motor. The motor drives the rotating rod and the skimming fan blades to skim the scum to the L-shaped storage port. The skimmed impurities enter the first storage box through the storage port. In order to prevent the hydroxide from clogging the concave screen, the operator starts the second motor. The motor drives the mounting block and the bevel gear to move the concave arc block up and down, thereby driving the screen to move and screen out the blocked hydroxide by shaking. The screened hydroxide falls above the vibrating net and is discharged to the second storage box through the opening of the square frame. The moisture in the hydroxide is collected by filter cotton and needs to be replaced regularly. The second storage box has two collection slots, the top is used to collect liquid, and the front side is used to collect hydroxide.

[0069] 2. Optimization of electrolysis process: The operation status of the device is controlled by the intelligent controller. The conductivity sensor, flow meter and pH sensor can accurately monitor the black water and oil-water in the electrolytic cell, thereby optimizing the electrolysis process and improving the separation efficiency. It is convenient for observation and maintenance: the glass plate is embedded and fixed at the front end of the separation box, so that personnel can directly observe the black water scum of the oil-water layer in the separation box, which is convenient for maintenance and monitoring, and the oil-water separation efficiency is high: the reverse osmosis device is interconnected with the L-shaped connecting pipe, and the oil and water are separated by a reverse osmosis membrane. The oil molecules cannot pass through the membrane, but the water molecules can pass through, achieving efficient separation.

[0070] 3. Centralized cleaning of hydroxides: The intelligent valve installed in the conical tank can discharge the water and hydroxides in the electrolytic cell. The screening mechanism further separates the black water and hydroxides to improve the cleaning efficiency and prevent clogging: Through the vibration and spiral transmission of the plastic spiral transmission leaves, the connection port of the concave screen can be effectively prevented from being blocked, thereby improving the stability and operation efficiency of the system.

[0071] 4. When the third bevel gear rotates, it will synchronously drive the fourth bevel gear through meshing. As the fourth bevel gear rotates, the fourth rotating rod fixedly connected to it will also start to rotate. Subsequently, the rotation of the fourth rotating rod will be transmitted to the two fifth gears and two second cam wheels connected to it. As the two second cam wheels rotate, they will slide in the track formed by the two concave arc blocks. During this sliding process, the second cam wheel will periodically push the two concave arc blocks, thereby driving the vibration net to move upward. At the same time, the four springs use their own elastic characteristics to accumulate energy when the concave screen rises, and under the action of the spring force, the concave screen produces rhythmic shaking. This shaking effectively shakes off the hydroxide particles that may be blocked inside the screen, keeping the screen unobstructed. BRIEF DESCRIPTION OF THE DRAWINGS

[0150] For details, please refer to Figure 1-Figure 9 Two second limiting grooves 603 are provided at the front end of the separation box 1 , and the first storage box 3 is slidably connected in the two second limiting grooves 603 .

[0151] In this embodiment: the second limiting groove 603 matches the first storage box 3, and the two second limiting grooves 603 can limit the first storage box 3, so that the first storage box 3 can stably collect the scum of the oil layer, so that the scum and the oil layer are separated, and it is also more convenient for subsequent personnel to replace and disassemble the first storage box 3.

[0152] The working principle and use process of the present invention are as follows: when the personnel conduct preliminary separation of oil and water, the personnel only need to use the intelligent controller 2 to start the air pump 13 and the reverse osmosis device 602. The oil and water sucked by the suction pump 8 and the black water are transmitted to the reverse osmosis device 602. The reverse osmosis membrane in the reverse osmosis device 602 separates the oil and water. The oil molecules cannot pass through the membrane due to their size and polarity, while the water molecules can pass through the membrane, thereby achieving separation. The oil that cannot be separated will be discharged through the threaded interface of the reverse osmosis device 602, while the water will be discharged through the reverse osmosis device 602 to the discharge hole 7012, so that the black water will re-enter the separation box 1, and the water will provide the discharge hole 7012 to re-enter the electrolytic cell 20. When the air pump 13 is restarted, the external gas will be introduced The gas in the air pipe 12 is then transmitted to the two shunt pipes 701. The two shunt pipes 701 will shunt the gas in the air pipe 12 and transmit it to the bottom inner wall of the electrolytic cell 20. Then, in conjunction with the rotation of the impeller 702, since the two impellers 702 themselves have connection holes, when the fifth rotating rod 7010 rotates, it will drive the impeller 702 to rotate synchronously. Then, the impeller 702 will break up the gas to form bubbles. Then, the bubbles will float upward through the black water and the oil and water, and bring the impurities inside the liquid to the top of the oil layer to form scum. Then, the scum is processed by the two skimming blades 7013 in the skimming cleaning mechanism 7. The skimmed impurities will fall into the L-shaped receiving port 604. The impurities will then enter the first receiving port 604 through the L-shaped receiving port 604. A storage box 3 is used to achieve the final collection. When separating the black water, the personnel use the intelligent controller 2 to start the cathode 707 and the anode 703. The black water passes through the electrolytic cell 20. During the electrolysis process, the salt in the black water is decomposed into hydroxide and hydrogen. At the same time, oil, water, scum and other components are also electrolyzed and separated. When the decomposed hydroxide is pushed and collected, the personnel only need to use the intelligent controller 2 to start the first motor 14. The output shaft of the first motor 14 will immediately drive one of the first rotating rods 405 to rotate, and one of the first rotating rods 405 will drive one of the first pulleys 4011 and one of the third gears 404 on the surface to rotate, and one of the third gears 404 will drive the first toothed belt 403 on the surface to rotate, so that the first toothed belt 4 03 transmission drives another third gear 404 to drive the first rotating rod 405 to rotate, so that the two first rotating rods 405 can rotate synchronously, so that the two first rotating rods 405 can drive the two skimming blades 7013 on the surface to flip and skim the floating scum on the upper side of the oil layer into the L-shaped receiving port 604 to achieve separation, and the skimmed impurities will fall into the L-shaped receiving port 604, and the impurities will enter the first receiving box 3 through the L-shaped receiving port 604 to achieve final collection. When one of the first pulleys 4011 rotates, it will drive the first belt 4012 on the surface to rotate, and the first belt 4012 will drive another first pulley 4011 inside to rotate, so that the first pulley 4011 drives the first gear 401 to rotate.The first gear 401 will drive the two second gears 402 on the surface to rotate, and the two second gears 402 will synchronously drive the two screw rods 709 to rotate. The rotation of the two screw rods 709 will drive the four nuts 708 on the surface to approach each other and move. While moving, the nuts 708 will drive the four moving push plates 705 to slide on the lower inner wall of the electrolytic cell 20, so that the four moving push plates 705 push the hydroxide produced by electrolysis on the lower inner wall of the electrolytic cell 20 until the four moving push plates 705 are close, so that the hydroxide will fall into the square frame 5016 through the conical groove 706, and then the hydroxide and the liquid will be separated again through the cooperation of the components in the screening mechanism 5, and the hydroxide will fall into the square frame 5 through the opening and closing of the intelligent valve 704. 016, because the concave screen 507 is concave, the inner wall of the concave screen 507 is in a semicircular arc shape, when the plastic spiral transmission blade 505 rotates, the hydroxide in the concave screen 507 will be cleaned out, so that the hydroxide enters the first threaded sleeve 502 through the second threaded sleeve 503 to achieve final collection. In order to prevent the hydroxide from clogging the concave screen 507, the personnel use the intelligent controller 2 to start the second motor 15, and the output shaft of the second motor 15 immediately drives the first mounting block 506 to rotate. When the first mounting block 506 rotates, it will drive one of the second pulleys 24 on the surface to rotate, and then one of the second pulleys 24 will drive the second belt 25 on the surface to rotate, and the second belt The belt 25 will drive another second pulley 24 on the inner wall of the circle to rotate, so that another second pulley 24 drives the third bevel gear 22 to rotate through the third mounting block 21, and then the third bevel gear 22 will drive the fourth bevel gear 23 on the circle surface to rotate, and the fourth bevel gear 23 will drive the fourth rotating rod 5015 to rotate, and then the fourth rotating rod 5015 drives the fifth gear 406 and the two second convex wheels 5014 on the surface to rotate, so that the two second convex wheels 5014 will lift up the two concave arc blocks 5013 during the rotation process, so that the two concave arc blocks 5013 move up and down repeatedly, and the concave screen 507 will be driven to move during the movement of the two concave arc blocks 5013, and when the concave screen 507 is downward, the concave screen 507 will move downward. 07 will squeeze the four springs 504 at the bottom to make them contract. The spring 504 itself has elasticity. When the second convex wheel 5014 does not lift the concave arc block 5013, the elasticity of the spring 504 will be reset. Repeated shaking of the concave screen 507 will screen out the blocked hydroxide. The screened hydroxide will fall on the top of the vibration net 5017, and then be discharged into the second storage box 601 through the opening of the square frame 5016 to achieve the final collection. The moisture contained in the hydroxide is collected by the filter sponge 5012. The filter sponge 5012 needs to be replaced regularly. The second storage box 601 itself has two collection slots. The top collection slot is used to collect liquids, and the front collection slot is used to collect hydroxides.
