DETAILED DESCRIPTION

[0019] like Figure 1 As shown, a medium frequency induction heating oil-water separation control system includes a separation box 1, a confluence groove 11 is fixedly connected to the upper part of the inner box wall on one side of the separation box 1, and the confluence groove 11 extends out of the separation box 1. A fixed block 5 is also fixedly connected to the bottom of the separation box 1. A groove is provided on the surface of the fixed block 5, and a slider 6 is embedded in the groove. The slider 6 can slide up and down in the groove on the surface of the fixed block 5. An induction coil 2 is also provided on the outer surface of the separation box 1.

[0020] A deviation sensor 8 and an auxiliary roller 9 are provided on one side of the slider 6. The deviation sensor 8 and the auxiliary roller 9 are fixed to the surface of one side of the slider 6 through a connecting rod. Teeth are evenly distributed on the surface of the other side of the slider 6. A steel belt is mounted on the surface of the auxiliary roller 9. The steel belt is annular. The deviation sensor 8 is concave. One side of the annular steel belt passes through the middle depression. The relative side arm of the deviation sensor 8 is magnetic. When the steel belt passes through it, the induced current generated in the deviation sensor 8 is a certain value. When the steel belt deviates inside it, the area of ​​the steel belt in the deviation sensor 8 will change, and the induced current generated in the deviation sensor 8 will also increase or decrease. The control system will determine whether the steel belt is tilted toward the inside of the deviation sensor 8 or the outside of the deviation sensor 8 according to the changing induced current in the deviation sensor 8. A lifting component 7 is also provided on the other side of the slider 6.

[0021] like Figure 2 and Figure 3 As shown, the lifting assembly 7 includes an upper rotating shaft 25 and a lower rotating shaft 26, and the upper rotating shaft 25 and the lower rotating shaft 26 are fixedly installed on the inner box wall on one side of the separation box 1 through a cross bar. A torsion spring is arranged in the upper rotating shaft 25, and a check plate 28 is arranged on the surface of the upper rotating shaft 25, and a paddle 27 is arranged on the surface of the lower rotating shaft 26. A notch is opened on the lower surface of the end of the check plate 28, and a lifting column 29 is also fixedly connected to the side of the check plate 28. A support column 39 is also arranged between the upper rotating shaft 25 and the lower rotating shaft 26, and the support column 39 is fixedly connected to the inner box wall on one side of the separation box 1, and a turntable motor 32 is fixedly connected to the end of the support column 39. The end of the driving shaft of the turntable motor 32 is also fixedly connected to the turntable 30, and a driving block 33 is also fixedly connected above the turntable 30. The surfaces on both sides of the driving block 33 are sloped. A connecting column 38 is also fixedly connected to the center of the surface of the turntable 30. A lifting gear 31 is provided on the surface of the connecting column 38, and a bearing 37 is provided between the two. A first rotating shaft 34 is also provided on one side of the surface of the turntable 30. A connecting rod is connected between the first rotating shaft 34 and the lower rotating shaft 26, and a second rotating shaft 35 is also provided on the connecting rod. The notch of the check plate 28 is just located in a tooth of the lifting gear 31, and the lifting gear 31 is also meshed with the slider 6 through teeth.

[0022] like Figure 1As shown, the separation box 1 is also fixedly connected to a column 13 at the bottom, and a cylinder 14 is provided on the surface of the column 13. The cylinder 14 is hollow and can move up and down on the surface of the column 13. A floating body is fixedly connected to the upper end of the cylinder 14, and an ultrasonic liquid level sensor 40 is also fixedly connected to the surface of the floating body. By utilizing the different densities of water and oil, the floating body can float in the water and sink in the oil. The oil layer is located above the ultrasonic liquid level sensor 40. A feed port 4 is also provided above the separation box 1. The feed port 4 is in the shape of a trumpet and has a filter screen inside. An ultrasonic generator 3 is also fixedly connected to the bottom of the separation box 1.

[0023] like Figure 1 and Figure 4 As shown, a scraping assembly 10 is also provided between the deviation sensor 8 and the auxiliary roller 9. The scraping assembly 10 includes a scraper 36. The scraper 36 is placed at an angle. There is a group of scrapers 36 that are relatively distributed on the inner and outer surfaces of the steel belt. One end of a transfer groove 12 is fixedly connected under the scraper 36, and the other end of the transfer groove 12 is connected to the confluence groove 11.

[0024] When the oil-water mixture enters the separation box 1 through the feed port 4 and the ultrasonic liquid level sensor 40 detects the height of the water level, the turntable motor 32 starts and rotates one circle in a certain direction, driving the turntable 30 to rotate one circle, and through the connecting rod between the lower rotating shaft 26, the first rotating shaft 34 and the second rotating shaft 35, driving the paddle 27 to rotate one circle. When the paddle 27 passes through the upper lifting gear 31, it will extend into an adjacent tooth between the lifting gears 31. At this time, the jacking column 29 is just on the surface of the driving block 33. The jacking column 29 and the check plate 28 are jacked up to a certain height, so that the teeth above the lifting gear 31 are separated from the notch of the check plate 28. Therefore, the paddle 27 will drive the lifting gear 31 to rotate a distance of one tooth in a specific direction. When the driving block 33 leaves the jacking column 29, the check plate 28 Under the action of the torsion spring in the upper rotating shaft 25, the notch of the check plate 28 falls back into a tooth above the lifting gear 31, fixing the lifting gear 31 to prevent the lifting gear 31 from reversing or rotating by inertia. Similarly, when the turntable motor 32 rotates in the opposite direction, it will drive the lifting gear 31 to rotate in the opposite direction. The rotation of the lifting gear 31 will cause the slider 6 with meshing teeth to move up and down in the groove of the fixed block 5. The up and down movement of the slider 6 will drive the deviation sensor 8 and the auxiliary roller 9 fixed to its side to move up and down, thereby driving the steel belt on the surface of the auxiliary roller 9 to move up and down in the separation box 1. The control system will control the start and stop of the turntable motor 32 according to the water level detected by the ultrasonic liquid level sensor 40, so that the steel belt is just immersed in the oil and can better adhere to the oil.

[0025] like Figure 1 and Figure 5As shown, a driving roller 19 is provided below the transfer groove 12, and the driving roller 19 is located on both sides of the steel belt surface between the transfer groove 12 and the deviation sensor 8. The ends of the driving roller 19 are connected to a connector 16, and the driving roller 19 can rotate on the surface of the connector 16. A rotating gear 18 is also provided between the two, and the rotating gears 18 are meshed with teeth. A rotating motor 17 is also fixedly connected to the end of one of the driving rollers 19, and the rotating motor 17 is located in the connector 16. Correction bodies 15 are also fixedly connected at both ends of the connector 16, and correction grooves 20 are also opened in the correction body 15. The correction grooves 20 are arc-shaped and symmetrically distributed, and the two are on the same arc line. A correction rotating shaft 21 is provided in the correction groove 20, and the correction rotating shaft 21 is fixedly installed on the inner box wall of the separation box 1 through a cross bar.

[0026] The connecting body 16 is also provided with a deflection rotation axis 22 relative to the surface of the driving roller 19, and a cylinder rotation axis 23 is also provided obliquely below the deflection rotation axis 22. The cylinder rotation axis 23 is fixedly installed on the inner box wall of the separation box 1 through a cross bar, and a deflection cylinder 24 is also provided on the surface of the cylinder rotation axis 23. The deflection cylinder 24 and the deflection rotation axis 22 are connected by a connecting rod. When the deflection cylinder 24 is extended, the driving connecting body 16 is deflected upward along the correcting groove 20, thereby driving the driving roller 19 on the other side of the connecting body 16 to tilt downward. When the deflection cylinder 24 is retracted, the driving connecting body 16 is deflected downward along the correcting groove 20, thereby driving the driving roller 19 on the other side of the connecting body 16 to tilt upward.

[0027] When the steel belt is adjusted to a suitable position according to the water level detected by the ultrasonic liquid level sensor 40, the rotating motor 17 starts to rotate, and the driving roller 19 and the steel belt therebetween are driven to rotate through the meshing between the rotating gears 18. When the bottom steel belt carries oil stains through the scraper 36, it is scraped off by the scraper 36 and flows into the adapter groove 12, and flows out of the separation box 1 through the confluence groove 11. When the deviation sensor 8 detects that the steel belt is deflected, the deflection cylinder 24 will extend or retract to the appropriate position, and adjust the steel belt in time to return it to a normal state to prevent the bottom steel belt from being immersed in water and affecting the effect of the steel belt carrying oil stains. At the same time, the induction coil 2 and the ultrasonic generator 3 are started, and the induction coil 2 is fed with a medium-frequency induced current to heat the oil-water mixture in the separation box 1. The ultrasonic generator 3 emits ultrasonic waves into the separation box 1, and uses the vibration piercing effect of heating and ultrasonic waves to accelerate the rupture of tiny bubbles mixed in the oil and water.

[0028] like Figure 6As shown, a medium frequency induction heating oil-water separation control system also includes a central controller, which is connected to an input part and an output part. The central controller is used to receive data detected by the input part and send operating instructions to the output part to realize the automatic operation of various parts in the medium frequency induction heating oil-water separation control system. The central controller is also connected to a display screen, which is used to display the operating status and parameters of various parts in the medium frequency induction heating oil-water separation control system.

[0029] The input part includes a deviation sensor and an ultrasonic liquid level sensor, and the input part is used to monitor the operating data in the medium frequency induction heating oil-water separation control system. The output part includes an induction coil, an ultrasonic generator, a rotating motor, a deflection cylinder and a turntable motor.
