In terms of working principle, the device is provided with a stirring mechanism, oil-water is added into the feed pipe through the feed hopper and is guided to be discharged into the centrifugal screen cylinder inside the treatment tank, the third motor is started to drive the rotating shaft to drive the dispersion mesh plate and the stirring auger to rotate, and the inside of the treatment tank is stirred; at the same time, the air pump is started, air is sent to the aeration pipe through the connecting pipe and the annular pipe and is sprayed out, the air flotation treatment effect is generated, the dispersion mesh plate rotates to assist the dispersion of bubbles, the stirring auger promotes the stirring of the sewage, and a better air flotation oil removal separation function is realized. In addition, the first air cylinder and the decontamination mechanism are matched, after the air flotation dispersion is completed, the first air cylinder drives the first motor to move up and down, the stirring mechanism is pulled out of the treatment tank, and then the decontamination mechanism is moved to the top of the treatment tank to absorb and collect oil stains.

[0003] The above-mentioned device has obvious defects in actual application.

DETAILED DESCRIPTION

[0032] In order to further understand the features, technical means and specific purposes and functions achieved by the present application, the present application will be described in further detail below in combination with the drawings and specific embodiments.

[0033] Referring to Figures 1 to 13 As shown in the drawings, the high-efficiency closed-type cyclone oil removal combined device comprises a flow guide hopper 2, which is rotatably installed on the top of a treatment tank 1. The gap between the outer wall of the flow guide hopper 2 and the inner wall of the treatment tank 1 forms an oil collection space, which is used to converge the oil layer. The axial position of the flow guide hopper 2 is provided with a limiting shaft sleeve 21, which is sleeved on a stirring mechanism 11 inside the treatment tank 1. A transmission controller 22 is installed between the limiting shaft sleeve 21 and the driving end of the stirring mechanism 11. The inside of the flow guide hopper 2 is also provided with a liquid level detection device 3, which is used to detect the interface position of oil and water in the oil collection space. The outer wall of the flow guide hopper 2 is slidably provided with a filter adsorption device 4, which is used to suck oil. The bottom of the filter adsorption device 4 is rotatably provided with a lifting closing plate 5, which is used to close and control the area of the oil collection space. The device also comprises a secondary detection separation device 6 installed on the outside of the treatment tank 1, which is in communication with the output end of the filter adsorption device 4.

[0034] After the oil and water enter the inside of the treatment tank 1, the existing stirring mechanism 11 and aeration pipe 12 and other devices in the treatment tank 1 are started to perform rotational aeration treatment on the oil and water. During the rotational aeration process, the oil-water mixture is subjected to centrifugal force and bubble action, and the oil droplets rapidly float upwards, pass through the movable lifting closing plate 5 located on the outer wall of the flow guide hopper 2, and enter the oil collection space formed between the outer wall of the flow guide hopper 2 and the inner wall of the treatment tank 1. When a certain amount of oil and water is injected into the inside of the treatment tank 1, the injection of oil and water is stopped, and at this time, the oil is concentrated and stays in the oil collection space.

[0035] When oil-water separation operation is needed, the lifting closure plate 5 first performs the closing action to isolate the oil collection space from other areas in the treatment tank 1, so that the oil and water in the oil collection space remain relatively flat, avoiding the influence of violent shaking of oil and water on the separation effect in subsequent operations. Subsequently, the liquid level detection device 3 installed inside the flow guide bucket 2 is started to identify and detect the oil-water interface in the oil collection space, accurately determine the oil-water interface position, and provide data support for subsequent oil-water separation.

[0036] After the liquid level detection device 3 determines the oil-water interface position, the lifting closure plate 5 is opened and then moves up to the oil-water interface position and is closed again. In this process, the lifting closure plate 5 drives the filter adsorption device 4 to move up synchronously, so that the filter adsorption device 4 accurately stays in the oil layer area and prepares for the subsequent oil pumping operation.

[0037] After the filter adsorption device 4 reaches the oil layer area, it starts to perform the oil pumping operation on the separated oil and transports the pumped oil to the secondary detection and separation device 6 installed outside the treatment tank 1 and connected with the output end of the filter adsorption device 4. During the oil pumping process, the transmission controller 22 is started to drive the stirring mechanism 11 to rotate synchronously with the flow guide bucket 2. Since the filter adsorption device 4 is installed on the flow guide bucket 2, the rotation of the flow guide bucket 2 drives the filter adsorption device 4 to rotate synchronously. This synchronous rotation effectively improves the uniformity of the oil adsorption of the filter adsorption device 4, and by constantly changing the position of the suction end of the filter adsorption device 4, the accumulation of impurities in the suction end is avoided, thereby effectively improving the stability of the pumping process.

[0038] After the oil pumping is completed, the lifting closure plate 5 is opened and lowered to the initial position. Subsequently, the treatment tank 1 discharges the water after oil removal, preparing for the next oil-water treatment. At the same time, the secondary detection and separation device 6 performs sedimentation treatment on the incoming oil, and after a period of sedimentation, it detects again whether the pumped oil contains water. If water is detected, the water is discharged, and then the oil with the required purity is transported to the treatment area.

[0039] Referring to Figures 3 to 5 As shown in the figure, the transmission controller 22 includes a conical transmission wheel 221 fixedly installed on the driving end of the stirring mechanism 11, and a transmission contact wheel 222 slidably installed on the limiting shaft sleeve 21, the shaft center position of the transmission contact wheel 222 is provided with a conical butt joint groove 2221 matched with the conical transmission wheel 221, the outer side of the transmission contact wheel 222 is provided with a lifting bracket 223, the lifting bracket 223 is slidably connected with the flow guide bucket 2, the upper side of the lifting bracket 223 is provided with a first linear actuator 224, the driving end of the first linear actuator 224 extends downward through the lifting bracket 223, and the first spring 225 is installed between the driving end of the first linear actuator 224 and the lifting bracket 223.

[0040] When the stirring mechanism 11 needs to drive the diversion bucket 2 to rotate synchronously to improve the uniformity of oil adsorption and the stability of suction by the filter adsorption device 4, the first linear actuator 224 of the transmission controller 22 is activated. After receiving the start signal, the output end of the first linear actuator 224 begins to contract, compressing the first spring 225. After being compressed, the first spring 225 undergoes elastic deformation, generating an upward elastic force that pushes the lifting bracket 223 upward.

[0041] During the ascent of the lifting bracket 223, the transmission abutment wheel 222 mounted on it slides upward along the limiting bushing 21. As the transmission abutment wheel 222 rises, the conical docking groove 2221 at the axial center gradually approaches and eventually engages with the conical transmission wheel 221 fixed on the drive end of the stirring mechanism 11. Because the docking area between the conical transmission wheel 221 and the conical docking groove 2221 is provided with an anti-slip layer, a stable transmission connection can be achieved through the interaction of the anti-slip layer after they are engaged. At this time, the rotation of the drive end of the stirring mechanism 11 drives the conical transmission wheel 221 to rotate, and the conical transmission wheel 221 transmits the rotational power to the transmission abutment wheel 222 through the conical docking groove 2221.

[0042] After receiving rotational power, the transmission contact wheel 222 begins to rotate, and the rotation of the transmission contact wheel 222 directly drives the diversion bucket 2 to rotate synchronously. When the diversion bucket 2 rotates, the filter adsorption device 4 installed on the outer wall of the diversion bucket 2 also rotates synchronously, thereby realizing the synchronous rotation of the diversion bucket 2 and the filter adsorption device 4 through the rotation of the stirring mechanism 11, achieving the purpose of improving the adsorption uniformity and suction stability of the filter adsorption device 4.

[0043] See Figure 3 and Figure 4 As shown, the liquid level detection device 3 includes a limiting lifting plate 31 that is slidably mounted on the limiting bushing 21. Multiple first ultrasonic liquid level detectors 32 are distributed on the limiting lifting plate 31. The first ultrasonic liquid level detectors 32 are used to detect the interface position of oil and water in the oil collecting space. A lifting adjustment screw 33 is installed between the limiting lifting plate 31 and the diversion bucket 2.

[0044] The lifting adjustment screw 33 is driven by the first rotary driver 34.

[0045] When the oil-water separation operation is needed, the lifting closure plate 5 completes the closing action to keep the oil and water in the oil collection space relatively flat, and then the first rotary driver 34 is started. Since the lifting adjusting screw rod 33 is connected with the output shaft of the first rotary driver 34, the rotation of the first rotary driver 34 will drive the lifting adjusting screw rod 33 to rotate synchronously. The lifting adjusting screw rod 33 is threadedly connected with the limiting lifting plate 31, and when the lifting adjusting screw rod 33 rotates, the limiting lifting plate 31 will move up and down along the limiting shaft sleeve 21 under the action of the thread. The limiting shaft sleeve 21 provides a guiding action for the movement of the limiting lifting plate 31, ensuring the linearity and stability of the movement.

[0046] When the limiting lifting plate 31 moves up and down, the plurality of first ultrasonic liquid level detectors 32 installed on the limiting lifting plate 31 also move up and down synchronously. The first ultrasonic liquid level detector 32 detects the liquid level by using the propagation characteristics of ultrasonic waves. With the movement of the limiting lifting plate 31, the plurality of first ultrasonic liquid level detectors 32 continuously emit and receive ultrasonic waves at different height positions in the oil collection space, and real-time liquid level information at different positions is obtained. Through comprehensive analysis and processing of the data of multiple detection points, the position of the oil-water interface in the oil collection space can be accurately determined.

[0047] Referring to Figures 3 to 11 As shown in the figure, the filter adsorption device 4 includes a rotary mounting ring 41 slidingly mounted on the side of the drainage hopper 2. The outer side of the rotary mounting ring 41 is provided with a plurality of suction heads 413. Each suction head 413 is provided with a clamping mounting groove 411 on the disc side. Each clamping mounting groove 411 is provided with an anti-blocking protection mechanism 45 and an elastic buckle 412. The elastic buckle 412 is used for clamping and fixing the anti-blocking protection mechanism 45. The top of the rotary mounting ring 41 is rotatably provided with a suction rail 42. The inside of the suction rail 42 is in communication with the suction head 413. The top of the suction rail 42 is provided with a limiting guide column 43 which is slidingly connected with the treatment tank 1. The axis position of the limiting guide column 43 is provided with a suction hole. The filter adsorption device 4 further includes a suction pump 44. The input end of the suction pump 44 is in communication with the suction hole, and the output end of the suction pump 44 is in communication with the secondary detection separation device 6.

[0048] The suction pump 44 is started, and under the negative pressure of the pump, the oil in the oil collection space enters the suction pump 44 in sequence through the plurality of suction heads 413, the suction track 42 and the suction hole. The specific process is as follows: the negative pressure generated by the suction pump 44 is transmitted to the suction hole, and since the suction hole is in communication with the inside of the suction track 42, the negative pressure is further transmitted to the suction track 42, and the suction track 42 is connected with each suction head 413, so that the negative pressure finally acts on the suction head 413, so that the oil around the suction head 413 is sucked into the inside of the suction head 413, and enters the suction pump 44 along the path of the suction head 413, the suction track 42 and the suction hole, realizing the oil suction operation, and the suction pump 44 delivers the sucked oil to the secondary detection and separation device 6.

[0049] During the oil pumping process, the transmission controller 22 of the drainage hopper 2 is started, so that the drainage hopper 2 rotates synchronously with the stirring mechanism 11. Since the rotating installation ring 41 of the filter adsorption device 4 is slidingly installed on the side of the drainage hopper 2, the rotation of the drainage hopper 2 drives the rotating installation ring 41 to rotate synchronously. When the rotating installation ring 41 rotates, the suction track 42 rotatingly installed on the top thereof is slidingly connected with the treatment tank 1 through the limiting guide column 43, and under the sliding constraint of the treatment tank 1, the limiting guide column 43 ensures that the suction track 42 remains relatively stable during the rotation of the rotating installation ring 41, and does not shake or displace due to the rotation of the rotating installation ring 41, thereby ensuring the stability of the suction system.

[0050] The rotating installation ring 41 rotates synchronously with the plurality of suction heads 413 and the anti-blocking protection mechanism 45 installed on the outside. This synchronous rotation mode enables the suction heads 413 to continuously move and suck in the oil layer area, changes the traditional fixed-position suction mode, effectively expands the suction range, improves the uniformity of suction, and avoids the problem of low suction efficiency caused by local over-suction or insufficient suction. At the same time, by continuously changing the position of the suction end of the suction head 413, the impurities in the oil are not easy to accumulate at the suction end, thereby effectively improving the stability of the suction process.

[0051] The disc side of each suction head 413 is provided with a clamping installation groove 411, and the anti-blocking protection mechanism 45 is installed on the clamping installation groove 411 and is clamped and fixed by the elastic buckle 412. The anti-blocking protection mechanism 45 can effectively filter the impurities in the oil and prevent the impurities from entering the inside of the suction head 413 to cause blockage. During the suction process, when the oil passes through the anti-blocking protection mechanism 45, the impurities are intercepted on the surface of the anti-blocking protection mechanism 45, and the clean oil passes through the anti-blocking protection mechanism 45 to enter the suction head 413, ensuring smooth operation of the suction process.

[0052] The elastic buckle 412 cooperates with the clamping installation groove 411, making the installation and disassembly of the anti-blocking protection mechanism 45 more convenient and fast. When the anti-blocking protection mechanism 45 is blocked due to long-term use or needs to be cleaned and replaced, the operator can press the elastic buckle 412 to separate it from the clamping installation groove 411, so that the anti-blocking protection mechanism 45 can be easily removed for cleaning or replacement.

[0053] Referring to Figures 6 to 11 As shown, the anti-blocking protection mechanism 45 includes a clamping bracket 451 installed on the clamping installation groove 411, and a rotating filter cover 452 and a cleaning brush 453 are installed on the clamping bracket 451. The rotating filter cover 452 is sleeved on the outside of the suction head 413, and the clamping bracket 451 is also rotatably installed with a friction roller 454, which is in transmission connection with the rotating filter cover 452. The anti-blocking protection mechanism 45 includes a friction tooth rail 455 installed on the lifting sealing plate 5, which is in contact with the friction roller 454.

[0054] The clamping bracket 451 of the anti-blocking protection mechanism 45 is docked with the clamping installation groove 411 on the disc side of the suction head 413, and the clamping bracket 451 is accurately positioned and firmly installed in the specified position through the clamping and fixing action of the elastic buckle 412. At this time, the rotating filter cover 452 sleeved on the clamping bracket 451 is sleeved on the outside of the suction head 413, forming a surrounding protection structure for the suction head 413, and preparing for the subsequent filtering operation. At the same time, the friction tooth rail 455 installed on the lifting sealing plate 5 is in contact with the friction roller 454 rotatably installed on the clamping bracket 451.

[0055] When the suction pump 44 is started and the oil is sucked by the suction head 413, the rotating filter cover 452 starts to play a filtering function. The impurities in the oil are intercepted on the surface when passing through the rotating filter cover 452, and the clean oil can smoothly pass through the rotating filter cover 452 into the inside of the suction head 413, thereby realizing effective filtering of impurities in the oil and preventing impurities from entering the suction head 413 to cause blockage, ensuring the initial smoothness of the suction process.

[0056] In the oil pumping process, the guide hopper 2 drives the rotary mounting ring 41 to rotate, and the rotary mounting ring 41 drives the plurality of suction heads 413 and the clamping bracket 451 mounted on the outer side to rotate synchronously. The clamping bracket 451 drives the friction roller 454 to rotate during rotation. Since the friction roller 454 is in contact with the friction tooth rail 455 mounted on the lifting sealing plate 5, under the action of friction, the friction roller 454 rotates while moving along the friction tooth rail 455. When the friction roller 454 rotates, it drives the rotating filter cover 452 to rotate synchronously through the transmission connection. At the same time, the cleaning brush 453 mounted on the clamping bracket 451 is in contact with the surface of the rotating filter cover 452. During the rotation of the rotating filter cover 452, the cleaning brush 453 and the surface of the rotating filter cover 452 are relatively rubbed, which can effectively remove the impurities intercepted on the surface of the rotating filter cover 452. Through this continuous cleaning effect, it prevents impurities from accumulating on the surface of the rotating filter cover 452 to form blockage, ensures that the filter aperture of the rotating filter cover 452 always remains unobstructed, improves the flow of suction, and ensures that the suction process can be continuously and stably carried out. The device realizes effective filtering and cleaning of impurities in oil, effectively avoids the blockage problem of the suction head 413, and improves the working efficiency and reliability of the filter adsorption device 4.

[0057] Referring to Figures 3 to 10 As shown, the lifting sealing plate 5 includes a limiting mounting plate 51 rotatably mounted at the bottom of the filter adsorption device 4, a plurality of first flow-through holes 511 are arranged on the limiting mounting plate 51, a rotating sealing plate 52 is rotatably mounted in the limiting mounting plate 51, a plurality of second flow-through holes 521 corresponding to the first flow-through holes 511 are arranged on the rotating sealing plate 52, a plurality of second springs 53 are mounted between the rotating sealing plate 52 and the limiting mounting plate 51, an installation guide column 54 is further mounted on the limiting mounting plate 51, an installation hole is arranged at the axial position of the installation guide column 54, a second linear actuator 56 is mounted on the installation guide column 54, the output end of the second linear actuator 56 extends into the installation hole, and a pull rope 55 is arranged between the output end of the second linear actuator 56 and the rotating sealing plate 52. The lifting sealing plate 5 further includes a third linear actuator 57 for driving the limiting mounting plate 51 to move up and down.

[0058] The limiting installation plate 51 of the lifting closing plate 5 is rotationally installed at the bottom of the filter adsorption device 4, and provides a basic installation position for the whole lifting closing plate 5. The limiting installation plate 51 is provided with a plurality of first flow-through holes 511 for normal flow of oil and water. The rotationally installed rotating closing plate 52 is provided with a plurality of second flow-through holes 521 corresponding to the first flow-through holes 511. In the initial state, the two are in a relative position to realize the flow of oil and water. A plurality of second springs 53 are installed between the rotating closing plate 52 and the limiting installation plate 51, and provide elastic force for subsequent reset action. The installation guide column 54 on the limiting installation plate 51, the installation hole at the shaft center position, and the second linear driver 56 installed on the installation guide column 54 provide structural support for the installation and action of the pull rope 55. The third linear driver 57 is fixedly installed at the top of the treatment tank 1, and the output end of the third linear driver 57 is connected with the limiting installation plate 51, thereby providing power for the lifting movement of the limiting installation plate 51.

[0059] When oil-water separation operation is needed, the closing action is first performed to isolate the oil collection space from other areas in the treatment tank 1. The third linear driver 57 is started to drive the limiting installation plate 51 to move downward, so that the lifting closing plate 5 as a whole reaches the specified closing position. At this time, in order to ensure that oil and water cannot pass through the first flow-through holes 511 of the limiting installation plate 51, the second linear driver 56 is started to pull the pull rope 55. When the pull rope 55 is subjected to the pulling force, the rotating closing plate 52 is rotated relative to the limiting installation plate 51. With the rotation of the rotating closing plate 52, the second flow-through holes 521 and the first flow-through holes 511 on the limiting installation plate 51 are gradually misaligned with each other. When the misalignment reaches a certain degree, the first flow-through holes 511 are blocked, and oil and water cannot flow through the first flow-through holes 511, thereby realizing the closing of the oil collection space. In this process, the rotating closing plate 52 is rotated due to the pulling force of the pull rope 55, so that the second spring 53 is compressed to store elastic potential energy.

[0060] After the oil-water interface position is determined by the liquid level detection device 3, the lifting sealing plate 5 needs to be opened and moved up to the oil-water interface position to be sealed again, so that the filter adsorption device 4 can be accurately stopped in the oil layer area. At this time, the second linear actuator 56 releases the pull rope 55, and the pulling force of the pull rope 55 on the rotating sealing plate 52 disappears. Under the elastic force of the second spring 53 which is compressed before, the second spring 53 releases energy and drives the rotating sealing plate 52 to reset and rotate. With the resetting of the rotating sealing plate 52, the first flow-through hole 511 and the second flow-through hole 521 correspond to each other again, and the oil and water can flow through the first flow-through hole 511 again, that is, the lifting sealing plate 5 is opened. At the same time, the third linear actuator 57 continues to act, driving the limiting mounting plate 51 to move up, and the lifting sealing plate 5 as a whole and the filter adsorption device move up synchronously until reaching the oil-water interface position. After reaching the specified position, the third linear actuator 57 stops acting, and the lifting sealing plate 5 seals the oil collecting space again, preparing for the subsequent oil pumping operation.

[0061] Referring to Figure 9 As shown, the bottom of the lifting sealing plate 5 is also provided with a plurality of outer wall scraping mechanisms. The outer wall scraping mechanism comprises a mounting bracket 582 fixedly installed at the bottom of the limiting mounting plate 51, an arc-shaped scraper 581 slidingly installed on the mounting bracket 582, and a third spring 583 installed between the arc-shaped scraper 581 and the mounting bracket 582.

[0062] When the device is in a normal working state and the lifting sealing plate 5 does not move up and down, the third spring 583 pushes the arc-shaped scraper 581 to move along the mounting bracket 582 to the outside of the drainage hopper 2 under the elastic force of the third spring 583, until the arc-shaped scraper 581 is in real-time abutted against the outside of the drainage hopper 2. At this time, the arc-shaped scraper 581 is in close contact with the outside of the drainage hopper 2, preparing for the subsequent dirt scraping.

[0063] When the lifting sealing plate 5 moves up and down under the driving of the third linear actuator 57, the outer wall scraping mechanism moves synchronously. Since the arc-shaped scraper 581 is always abutted against the outside of the drainage hopper 2 under the action of the third spring 583, the arc-shaped scraper 581 will slide along the outer surface of the drainage hopper 2 during the lifting or lowering of the lifting sealing plate 5. This relative sliding enables the arc-shaped scraper 581 to scrape the dirt attached to the outer surface of the drainage hopper 2, and peel off the dirt from the outside of the drainage hopper 2. With the continuous lifting and lowering of the lifting sealing plate 5, the arc-shaped scraper 581 will scrape the outside of the drainage hopper 2 multiple times to ensure the cleanliness of the outside of the drainage hopper 2.

[0064] If the dirt outside the drainage hopper 2 is not cleaned in time, it may interfere with the detection accuracy of the oil-water interface position by the liquid level detection device 3. The outer wall scraping mechanism continuously scrapes and cleans the outside of the drainage hopper 2, effectively removing the dirt attached to the outside of the drainage hopper 2, reducing the interference of the dirt on the detection signal of the liquid level detection device 3. Thus, the liquid level detection device 3 can accurately determine the oil-water interface position, provide reliable data support for subsequent oil-water accurate separation, and improve the oil-water separation effect and operation stability.

[0065] Referring to Figures 1 to 13 As shown, the secondary detection and separation device 6 includes a liquid storage barrel 61 installed outside the treatment tank 1, the liquid storage barrel 61 is connected with the output end of the filter and adsorption device 4, the outer side of the liquid storage barrel 61 is provided with a movable end of a lifting lead screw sliding table 62, the second ultrasonic liquid level detector 63 is installed on the movable end of the lifting lead screw sliding table 62, and the bottom of the liquid storage barrel 61 is provided with a drain pipe 64 and an oil discharge pipe 65.

[0066] The drain pipe 64 and the oil discharge pipe 65 are each provided with a control valve.

[0067] After the filter and adsorption device 4 completes the oil suction operation in the oil collection space, the sucked oil is transported to the liquid storage barrel 61 installed outside the treatment tank 1 through the output end. Since a certain amount of water may be mixed in the oil during the suction process, when the oil enters the liquid storage barrel 61, the oil-water mixture begins to naturally precipitate under the action of gravity. Since the density of water is greater than that of oil, the water will gradually sink to the bottom of the liquid storage barrel 61, while the oil will float on the upper layer, forming an obvious oil-water stratification phenomenon.

[0068] After the oil-water in the liquid storage barrel 61 completes the preliminary precipitation and reaches a relatively stable state, the lifting lead screw sliding table 62 installed outside the liquid storage barrel 61 is started. The lifting lead screw sliding table 62 drives the second ultrasonic liquid level detector 63 to move in the vertical direction along the outer wall of the liquid storage barrel 61 through the movable end, so that the second ultrasonic liquid level detector 63 reaches the appropriate working position to accurately detect the oil layer inside the liquid storage barrel 61. The second ultrasonic liquid level detector 63 can accurately identify the interface position of the oil layer and the water layer by using the characteristics of ultrasonic wave propagation in the oil layer, and provide accurate data support for the subsequent oil-water separation operation.

[0069] After the second ultrasonic level detector 63 completes its detection, if the result indicates that the oil contains water, the system will control the control valve installed on the drain pipe 64 to open based on the detected oil interface position information. At this time, the water that has settled at the bottom of the storage tank 61 will be discharged into the treatment area through the drain pipe 64 under the action of gravity. During the drainage process, the drainage situation will be monitored in real time to ensure that the water is completely discharged while preventing oil from being discharged with the water. After the water is discharged, the control valve installed on the oil drain pipe 65 will open. The higher purity oil in the upper layer of the storage tank 61 will be transported to the treatment area through the oil drain pipe 65 under the action of gravity, completing the entire oil-water separation process.

[0070] See Figure 12 and Figure 13 As shown, the cleaning mechanism 66 includes a cleaning fluid nozzle 661 installed inside the liquid storage tank 61. The cleaning mechanism 66 also includes a rotating frame 662 installed inside the liquid storage tank 61. A scraper 663 is installed on the rotating frame 662 and contacts the inner wall of the liquid storage tank 61.

[0071] The rotating frame 662 is driven by the second rotary driver 664.

[0072] After repeated oil-water separation operations, dirt gradually accumulates on the inner wall of the storage tank 61. This dirt may consist of impurities in the oil, minerals in the precipitated water, and other residues generated during the processing. The adhesion of dirt alters the smoothness and optical properties of the inner wall of the storage tank 61, thereby affecting the accurate detection of the oil-water interface by the second ultrasonic level detector 63 installed on the outside of the storage tank 61. When the system detects that the dirt accumulation has reached a certain level or according to the preset cleaning cycle, the cleaning mechanism 66 initiates the cleaning program.

[0073] After the cleaning process is initiated, the cleaning fluid nozzle 661 installed inside the storage tank 61 connects to the external rinsing equipment. The rinsing equipment pressurizes the cleaning fluid, which has the ability to clean and dissolve dirt, and delivers it to the cleaning fluid nozzle 661. The cleaning fluid nozzle 661 sprays the cleaning fluid evenly onto the inner wall of the storage tank 61 according to a preset spray pattern. After the cleaning fluid comes into contact with the dirt, through chemical dissolution and physical wetting, the dirt gradually loosens and separates from the inner wall of the storage tank 61.

[0074] At the same time, the second rotary driver 664 installed inside the liquid storage barrel 61 is started. The second rotary driver 664 outputs torque to drive the rotating frame 662 connected thereto to rotate. The rotating frame 662 is provided with a scraping strip 663 in close contact with the inner wall of the liquid storage barrel 61. With the rotation of the rotating frame 662, the scraping strip 663 moves along the inner wall of the liquid storage barrel 61 in a circular motion. The scraping strip 663 is made of a material with certain hardness and toughness, and during rotation, the scraping strip 663 exerts appropriate pressure on the inner wall of the liquid storage barrel 61 to scrape off the dirt that has loosened but not completely fallen off from the inner wall. The scraping action of the scraping strip 663 cooperates with the chemical action of the cleaning liquid to more effectively remove dirt from the inner wall of the liquid storage barrel 61.

[0075] The dirt scraped off by the scraping strip 663 mixes with the cleaning liquid and deposits at the bottom of the liquid storage barrel 61 under the action of gravity. During cleaning, the drain pipe 64 at the bottom of the liquid storage barrel 61 can be temporarily opened as needed to discharge the cleaning liquid containing dirt to a designated waste liquid treatment area. After the cleaning operations such as spraying of the cleaning liquid and scraping by the scraping strip 663 are completed, the drain pipe 64 control valve is closed to stop the spraying of the cleaning liquid and the operation of the second rotary driver 664. At this time, the cleaning mechanism 66 completes a cleaning cycle, the inner wall of the liquid storage barrel 61 is restored to a clean state, ensuring that the second ultrasonic liquid level detector 63 can accurately detect the position of the oil-water interface, and ensuring the normal operation of the secondary detection and separation device 6 and the accuracy of oil-water separation.

[0076] Specific working principle:

[0077] After the oil and water enter the inside of the treatment tank 1, the existing stirring mechanism 11 and aeration pipe 12 and other devices in the treatment tank 1 are started to perform rotary aeration treatment on the oil and water. During the rotary aeration process, the oil-water mixture is subjected to centrifugal force and bubble action, and the oil droplets rapidly float up and pass through the movable lifting closure plate 5 located on the outer wall of the flow guide hopper 2 to enter the oil collection space formed between the outer wall of the flow guide hopper 2 and the inner wall of the treatment tank 1. When a certain amount of oil-water is injected into the treatment tank 1, the oil-water injection is stopped, and at this time the oil is concentrated and stays in the oil collection space.

[0078] When oil-water separation operation is needed, the lifting closure plate 5 first performs a closing action to isolate the oil collection space from other areas in the treatment tank 1, so that the oil and water in the oil collection space remain relatively calm, avoiding the influence of violent shaking of the oil and water on the separation effect in subsequent operations. Subsequently, the liquid level detection device 3 installed inside the flow guide hopper 2 is started to identify and detect the oil and water in the oil collection space, accurately determine the oil-water interface position, and provide data support for subsequent accurate separation of oil and water.

[0079] After the oil-water interface position is determined by the liquid level detection device 3, the lifting sealing plate 5 is opened, and then is moved upward to the oil-water interface position and is sealed again. In this process, the lifting sealing plate 5 drives the filter adsorption device 4 to move upward synchronously, so that the filter adsorption device 4 is accurately stopped in the oil layer region, and the subsequent oil pumping operation is prepared.

[0080] After the filter adsorption device 4 reaches the oil layer region, the pumping operation is started, the pumped oil is transported to the secondary detection and separation device 6 installed outside the treatment tank 1 and communicated with the output end of the filter adsorption device 4. In the oil pumping process, the transmission controller 22 is started, so that the stirring mechanism 11 drives the flow guide hopper 2 to rotate synchronously. Since the filter adsorption device 4 is installed on the flow guide hopper 2, the rotation of the flow guide hopper 2 drives the filter adsorption device 4 to rotate synchronously. This synchronous rotation mode effectively improves the uniformity of the oil adsorption of the filter adsorption device 4, and at the same time, by constantly changing the position of the pumping end of the filter adsorption device 4, the accumulation of impurities in the pumping end is avoided, thereby effectively improving the stability of the pumping process.

[0081] After the oil pumping is completed, the lifting sealing plate 5 is opened and lowered to the initial position. Subsequently, the treatment tank 1 discharges the water after oil removal, and prepares for the next oil-water treatment. At the same time, the secondary detection and separation device 6 performs sedimentation treatment on the entering oil, and after a period of sedimentation, it is detected again whether the pumped oil contains water. If water is detected, the water is discharged, and then the oil with the required purity is transported to the treatment area.

[0082] The device realizes efficient and convenient oil removal operation, and at the same time, the inside of the treatment tank 1 is relatively sealed from the outside during the whole process, avoiding the leakage of contaminated gas, effectively protecting the working environment, and meeting the requirements of modern industrial production on efficient and environmentally friendly equipment.

It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are within the protection scope of the present application.
