Description

Technical Field

[0001] The invention relates to the field of wastewater treatment, and in particular to oil removal equipment for producing epoxidized soybean oil. Background Art

[0002] When the existing epoxidized soybean oil is produced, the industrial wastewater generated by the production is usually discharged directly to a sewage treatment station for treatment. The direct discharge of production wastewater into a sewage pool will increase the oil content of the sewage in the sewage pool. Even if there is an oil skimmer in the sewage pool, the average daily oil recovery of the oil skimmer is small. If the production wastewater stays in the sewage pool for too long, it is easy to cause most of the oil in the sewage pool to gather and sink to the bottom. In the subsequent treatment process of the sewage, the sewage with a high oil content is easy to inhibit the growth of bacteria and destroy the balance of the bacterial flora, thereby reducing the sewage treatment volume and the discharged wastewater failing to meet the relevant industry standards.

[0003] For example, the patent with publication number CN211921082U, published on November 13, 2020, discloses an oil separation treatment device for the production of epoxidized soybean oil, including a base plate, an oil-water separation tank is fixedly connected to the top of one side of the base plate, an oil storage tank is fixedly connected to the top of the other side of the base plate, a motor is fixedly connected to the center of the top of the base plate, a threaded rod is gear-transmission connected to the motor, a movable tube is threadedly connected to the threaded rod, an oil outlet pipe is slidably connected to the center of the movable tube, the other end of the oil outlet pipe is arranged above the oil storage tank, the other end of the movable tube is fixedly connected to an oil guide pipe, a support rod is fixedly connected to the center of the bottom end of the oil guide pipe, a near-infrared detector is fixedly arranged on one side of the bottom end of the support rod, and an oil suction pipe and a near-infrared detector are arranged. Due to the different densities of oil and water, the oil-water boundary can be detected by the near-infrared detector, and then the motor drives the threaded rod to adjust the height of the oil suction pipe to suck the oil into the oil storage tank to complete the oil-water separation.

[0004] In the above-mentioned patent, the industrial wastewater generated by the existing epoxidized soybean oil production is discharged into the oil-water separation tank before being discharged into the sewage treatment station, and then the oil in the oil-water separation tank is extracted through the oil suction pipe to achieve the purpose of oil-water separation. Among them, as the oil in the oil-water separation tank is sucked out by the oil suction pipe, some oil remains on the cylinder wall. The oil suction pipe in the above-mentioned patent cannot suck out the oil remaining on the cylinder wall. Afterwards, a considerable part of the oil on the cylinder wall will be discharged into the sewage pool along with the industrial wastewater, and the bacteria in the sewage pool do not have the ability to treat oil pollution, resulting in incomplete and insufficient sewage treatment, especially the oil pollution floating on the surface of the sewage pool brings extremely poor visual perception. Summary of the invention

[0005] The purpose of the present invention is to provide an oil removal device for producing epoxidized soybean oil to solve the technical problems in the related art.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] An oil removal device for the production of epoxy soybean oil, comprising an oil-water separation tank and an oil storage tank, further comprising an oil absorption assembly. The oil absorption assembly is connected to the oil-water separation tank and the oil storage tank. The oil absorption assembly includes an oil suction pipe, a driving part and a suction part. A wiping part is installed on the side wall of the oil suction pipe, and the wiping part abuts against the wall of the oil-water separation tank. The driving part drives the wiping part to move along the wall of the oil-water separation tank to adsorb the oil stains adhering to the wall of the oil-water separation tank. The suction part performs a vacuum pumping treatment on the wiping part to drive the wiping part to separate from the adsorbed oil liquid.

[0008] As described above, one end of the oil suction pipe is inserted into the oil-water separation tank, and the other end of the oil suction pipe is inserted into the oil storage tank. A linear telescopic part is also connected to the oil suction pipe, and the linear telescopic part drives the oil suction pipe to move along the vertical direction to adjust the height of the end of the oil suction pipe in the oil-water separation tank.

[0009] As described above, one end of the oil suction pipe is inserted into the interior of the oil-water separation tank. The oil suction pipe located in the oil-water separation tank is sequentially divided into a first rigid part, a flexible part and a second rigid part from top to bottom. An adjusting sleeve is also provided outside the oil suction pipe, and the wiping part is slidably installed on the inner wall of the adjusting sleeve along the vertical direction.

[0010] As described above, the adjusting sleeve is sequentially divided into an adjusting section and a sliding section from top to bottom. The adjusting section corresponds to the flexible part, and the sliding section corresponds to the second rigid part. There are the following two states when the wiping part slides along the adjusting sleeve;

[0011] One is: the wiping part is located outside the second rigid part;

[0012] The other is: the wiping part is located outside the flexible part, the wiping part clamps the flexible part, and the connection between the first rigid part and the second rigid part is disconnected.

[0013] As described above, a blocking filter plate is also installed on the inner wall of the adjusting sleeve. The blocking filter plate is located at the connection between the first rigid part and the flexible part, and the blocking filter plate is placed horizontally.

[0014] As described above, the wiping part includes a first barrier member and a second barrier member. Both the first barrier member and the second barrier member are in a U shape. Both the first barrier member and the second barrier member are slidably installed on the inner wall of the adjusting sleeve along the vertical direction. An oil absorption cotton sleeve is jointly installed at the bottom ends of the first barrier member and the second barrier member. The oil absorption cotton sleeve abuts against the wall surface of the oil-water separation tank. The second barrier member is connected to the first barrier member through an elastic member. The inner wall of the adjusting section is inclined inward from bottom to top. The first barrier member and the second barrier member slide upward from bottom to top along the adjusting section, and the first barrier member and the second barrier member approach each other to clamp the flexible part, and the connection state between the first rigid part and the second rigid part changes from a connected state to a disconnected state.

[0015] As mentioned above, two vertical strips are symmetrically installed on the side wall of the sliding section, and sliding grooves are provided on the surfaces of the two strips close to the sliding section. The groove directions of the two sliding grooves are parallel to the axial direction of the sliding section. The two sliding grooves are connected to the inner cavity of the adjusting sleeve. Slide blocks are slidably installed in the two sliding grooves, and deflection baffles are hinged on the two slide blocks. Torsion springs are connected between the two deflection baffles and the slide blocks.

[0016] As mentioned above, the deflection baffle has the following two states:

[0017] One is: the slider is located at the bottom of the long strip, the slider presses the deflection baffle, and the deflection baffle is placed vertically;

[0018] The second is that the slider leaves the bottom of the strip, the deflection baffle loses the pressing force of the slider, and the torsion spring drives the deflection baffle to flip to a horizontal state.

[0019] As mentioned above, the adjusting sleeve is slidably connected with the oil suction pipe, and a trigger part is arranged on the oil suction pipe, and the trigger part is used to drive the adjusting sleeve to move in a vertical direction away from the oil-water separation tank.

[0020] As mentioned above, the triggering part includes two extension blocks, both of which are connected to the side walls of the blocking filter plate, and the two extension blocks correspond to the two long strips one by one. The two extension blocks are respectively inserted into the slide grooves on the two long strips, and an air guide hole is opened on the extension block. The axial direction of the air guide hole is parallel to the axis of the blocking filter plate. Two rotating rings are rotatably installed below the blocking filter plate, and the axes of the two rotating rings are parallel to the axis of the blocking filter plate. Shielding plates are installed on the side walls of the two rotating rings, and the two shielding plates are respectively inserted into the slide grooves of the two long strips. The two rotating rings correspond to the first blocking member and the second blocking member respectively, and a first wedge block is installed below the two rotating rings, and a second wedge block matching the first wedge block is installed above the first blocking member and the second blocking member.

[0021] The beneficial effect of the present invention lies in that: in the above technical scheme, the wiping part provided by the present invention, after the oil in the oil-water separation tank is extracted, the driving part drives the wiping part to move along the tank wall of the oil-water separation tank, and the oil on the tank wall of the oil-water separation tank is adsorbed by the wiping part, and then the suction part performs a vacuum treatment on the wiping part, driving the wiping part to separate from the oil absorbed by it, thereby completing the collection and treatment of the oil on the tank wall of the oil-water separation tank, reducing the oil on the tank wall of the oil-water separation tank being discharged into the sewage pool along with the industrial wastewater, resulting in an increase in the amount of oil in the sewage pool, which is easy to affect the treatment effect of the bacteria on the sewage, resulting in a decrease in the sewage treatment efficiency.

[0033] In order to enable those skilled in the art to better understand the technical solution of the present invention, Figure 1 - Attachment Figure 8 , the present invention is further introduced in detail.

[0034] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "degree", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0035] An oil removal device for producing epoxidized soybean oil provided in an embodiment of the present invention comprises an oil-water separation tank 1 and an oil storage tank 2. The oil storage tank 2 is in a circular shape and is sleeved on the outer side of the oil-water separation tank 1. It also comprises an oil suction assembly 3. The oil suction assembly 3 comprises an oil suction pipe 31 and a driving unit 32. One end of the oil suction pipe 31 is inserted into the oil-water separation tank 1, and the other end of the oil suction pipe 31 is inserted into the oil storage tank 2. An erasing unit 34 is installed on the side wall of the oil suction pipe 31 at one end of the oil-water separation tank 1. The erasing unit 34 is preferably oil absorbing paper or oil absorbing cotton. In this embodiment, the erasing unit 34 is specifically an oil absorbing unit. The surface of the oil-absorbing cotton as the wiping part 34 is against the tank wall of the oil-water separation tank 1. The driving part 32 includes a frame and a driving motor. The driving motor is installed on the frame. A linear telescopic part 35 is also installed on the frame. The linear telescopic part 35 is installed on the frame so as to revolve around the axis of the driving motor (preferably, an annular track is installed on the frame, the annular track is coaxially arranged with the driving motor, and the linear telescopic part 35 is slidably installed in the annular track). The telescopic end of the linear telescopic part 35 is connected to the oil suction pipe 31, and the linear telescopic part 35 drives the oil suction pipe 31 to move along the vertical direction. The oil suction pipe 31 is moved in the direction of rotation to adjust the height of the end of the oil suction pipe 31 in the oil-water separation tank 1, wherein the axial direction of the output shaft of the driving motor is coaxially arranged with the oil-water separation tank 1, and a horizontally arranged connecting rod is installed on the output shaft of the driving motor, and the other end of the connecting rod is fixedly connected to the linear telescopic part 35, so that as the driving motor works, the driving motor drives the connecting rod to revolve, and the revolution of the connecting rod drives the linear telescopic part 35 and the oil suction pipe 31, and the oil suction pipe 31 drives the erasing part 34 to move synchronously, so that the driving motor drives the erasing part 34 to rotate with the axis of the oil-water separation tank 1 as the center. That is, the revolution drives the wiping part 34 and the oil suction pipe 31 to move along the tank wall of the oil-water separation tank 1, and the oil-absorbing cotton of the wiping part 34 absorbs the oil stains adhered to the tank wall of the oil-water separation tank 1, wherein the oil-water separation tank 1 is also connected to a conveying module, and the conveying module is used to convey the industrial wastewater generated during the production of epoxidized soybean oil into the oil-water separation tank 1. The conveying module specifically includes a wastewater tank for storing the industrial wastewater and a conveying pipeline for conveying the industrial wastewater. One end of the conveying pipeline is connected to the wastewater tank, and the other end of the conveying pipeline is connected to the bottom end of the oil-water separation tank 1. This is the prior art and will not be repeated.

[0036] Specifically, the conveying pipeline conveys the industrial wastewater generated during the production of epoxidized soybean oil in the wastewater tank to the inside of the oil-water separation tank 1. When the industrial wastewater in the oil-water separation tank 1 reaches the set water level, the conveying pipeline stops conveying the industrial wastewater to the inside of the oil-water separation tank 1, and the industrial wastewater stands still in the oil-water separation tank 1. After the standing still, the industrial wastewater is separated into oil and water layers in the oil-water separation tank 1. Because the main component of the oil is vegetable oil extracted from soybeans as raw materials, the density of the oil is less than the density of water, so the epoxidized soybean oil will float on the water surface, that is, the industrial wastewater in the oil-water separation tank 1 will form an oil layer and a water layer after standing still. Then, according to the height of the oil layer in the oil-water separation tank 1, the linear telescopic part 35 starts to work, and the linear telescopic part 35 drives the oil suction pipe 31 to adjust the up and down position in the vertical direction, so that the oil suction pipe 31 inserted into the oil-water separation tank 1 1 moves along the axial direction of the collar to the position of the oil-water dividing line, and then the oil suction pipe 31 extracts the oil above the water surface. When the oil extraction process is performed, the driving motor starts to work, and the driving shaft of the driving motor drives the connecting rod to rotate, and the connecting rod drives the linear telescopic part 35 and the oil suction pipe 31 to revolve as a whole. At this time, the oil suction pipe 31 rotates with the axis of the oil-water separation tank 1 as the center of the circle, driving the oil-absorbing cotton as the wiping part 34 to move along the tank wall of the oil-water separation tank 1. The oil-absorbing cotton as the wiping part 34 absorbs the oil stains adhered to the tank wall of the oil-water separation tank 1, and completes the collection and treatment of the oil on the tank wall of the oil-water separation tank 1, so as to prevent the oil on the tank wall of the oil-water separation tank 1 from finally slowly sliding down and being discharged into the sewage pool along with the industrial wastewater, resulting in an increase in the amount of oil in the sewage pool, which is easy to affect the treatment effect of the bacteria on the sewage, resulting in a decrease in the sewage treatment efficiency.

[0037] It should be noted that in order to facilitate the observation of the boundary height between the water layer and the oil layer inside the oil-water separation tank 1, preferably, the oil-water separation tank 1 should be provided with a notch for observation, which is vertical and even and interconnected with the inner cavity of the oil-water separation tank 1, wherein the notch is sealed by transparent glass, and the exact boundary height between the water layer and the oil layer inside the oil-water separation tank 1 is determined by the transparent glass, and then the height of the oil suction pipe 31 inside the oil-water separation tank 1 is accurately adjusted by the linear telescopic part 35. Obviously, automatic identification and control based on color differences can also be achieved through sensors and other mechanisms. This is a prior art and will not be elaborated.

[0038] In addition, after a long period of use, the oil-absorbing cotton serving as the wiping part 34 will absorb a large amount of oil. When the oil absorption of the oil-absorbing cotton reaches saturation, the oil-absorbing cotton cannot continue to absorb oil. At this time, it is necessary to manually or automatically replace the oil-absorbing cotton that has reached the saturated adsorption state to ensure that the oil-absorbing cotton continues to absorb the oil stains on the inner wall of the oil-water separation tank 1. In this regard, in another embodiment of the present invention, a suction part 33 is also installed on the oil suction pipe 31, and the suction part 33 is used to vacuum the oil-absorbing cotton serving as the wiping part 34, so as to drive the oil-absorbing cotton to separate from the oil absorbed by it, so as to increase the service life of the oil-absorbing cotton serving as the wiping part 34 and ensure that the oil-absorbing cotton can continuously absorb the oil stains on the inner wall of the oil-water separation tank 1.

[0039] Among them, the oil suction pipe 31 located in the oil-water separation tank 1 is successively divided into a first rigid part 311, a flexible part 312 and a second rigid part 313 from top to bottom. Among them, the flexible part 312 is equivalent to a connecting channel to connect the first rigid part 311 and the second rigid part 313. The second rigid part 313 is inserted into the oil layer in the oil-water separation tank 1. An adjusting sleeve 36 is further arranged outside the oil suction pipe 31. In this embodiment, the cross-section of the adjusting sleeve 36 presents a regular polygon. Preferably, the cross-section of the adjusting sleeve 36 is rectangular. The connection part between the top of the adjusting sleeve 36 and the oil suction pipe 31 is located on the first rigid part 311. At the same time, the adjusting sleeve 36 is sleeved on the tops of the flexible part 312 and the second rigid part 313. A plurality of communication ports 314 are opened on the side wall of the first rigid part 311. The communication ports 314 connect the inner cavity of the adjusting sleeve 36 with the inner cavity of the first rigid part 311. The plurality of communication ports 314 are arranged at intervals along the circumferential direction of the first rigid part 311. The suction part 33 includes a suction pump, and the suction pump is communicated with the oil suction pipe 31. In this embodiment, the suction pump includes two working gears of low power and high power. The wiping part 34 is slidably installed on the inner wall of the adjusting sleeve 36 in the vertical direction. The adjusting sleeve 36 is successively divided into an adjusting section 361 and a sliding section 362 from top to bottom. The adjusting section 361 corresponds to the flexible part 312, and the sliding section 362 corresponds to the second rigid part 313. The wiping part 34 includes a first barrier 341 and a second barrier 343. Both the first barrier 341 and the second barrier 343 are in a U shape. The ends of the two are relatively sleeved to form a square shape to fit the adjusting sleeve 36 with a rectangular cross-section. A plurality of oil discharge holes 346 are evenly opened on the first barrier 341 and the second barrier 343. Both the first barrier 341 and the second barrier 343 are slidably installed in the space between the adjusting sleeve 36 and the second rigid part 313 in the vertical direction. That is, when the first barrier 341 and the second barrier 343 slide along the inner wall of the adjusting sleeve 36, the first barrier 341 and the second barrier 343 move away from or close to the oil layer inside the oil-water separation tank 1 in the vertical direction. An oil-absorbing cotton sleeve 342 is jointly installed at the bottom ends of the first barrier 341 and the second barrier 343. The oil-absorbing cotton sleeve 342 abuts against the wall surface of the oil-water separation tank 1. Among them, the U-shaped first barrier 341 includes a main body section and two pin sections. The two pin sections are respectively arranged at both ends of the main body section. The two pin sections are fixedly connected to the main body section. The first barrier 341 and the second barrier 343 have basically the same shape, and the shape of the second barrier 343 will not be described here. The size of the pin section of the first barrier 341 is larger than the size of the pin section of the second barrier 343. Relief notches 344 are opened on the end faces of the two pin sections of the first barrier 341 away from the main body section. The two relief notches 344 correspond to the two pin sections on the second barrier 343. The two pin sections on the second barrier 343 are inserted into the relief notches 344 on the first barrier 341.The pin section of the second blocking member 343 is connected to the first blocking member 341 via a traction spring 345, wherein the first blocking member 341 and the second blocking member 343 main body section away from the pin section are inclined from top to bottom toward the outside, the inner wall of the adjustment section 361 is inclined from bottom to top toward the inside, and the inclination of the main body section on the first blocking member 341 and the second blocking member 343 is consistent with the inclination of the inner wall of the adjustment section 361, and the first blocking member 341 and the second blocking member 343 are inclined from bottom to top along the adjustment section 361. When the first blocking member 341 and the second blocking member 343 pass through the adjusting section 361, the first blocking member 341 and the second blocking member 343 approach each other to clamp the flexible portion 312, so that the flexible portion 312 as the connecting channel between the first hard portion 311 and the second hard portion 313 is closed or substantially closed, and a limit block is provided at the bottom end of the sliding section 362, and the limit block is used to limit the first blocking member 341 and the second blocking member 343 from being separated from the adjusting sleeve 36. In the initial state, the erasing portion 34 is located in the sliding section 362. The bottom end of the first barrier 341 and the second barrier 343 is at the bottom end, at this time, the traction spring 345 connecting the first barrier 341 and the second barrier 343 is in a stretched state, and the combined first barrier 341 and the second barrier 343 just block the gap between the second hard portion 313 and the adjustment sleeve 36 (the gap here is the area between the outer wall of the second hard portion 313 and the inner wall of the adjustment sleeve 36). When the first barrier 341 and the second barrier 343 are located at the flexible portion 312, the traction spring 345 returns to its original state, pulling the first barrier 341 and the second barrier 343 to close the gap between the second hard portion 313 and the adjustment sleeve 36. The first and second blocking members 343 are close to each other, clamping the flexible portion 312, driving the first hard portion 311 and the second hard portion 313 from the connected state to the disconnected state. When the suction pump is working in a low-power state, the suction force of the suction pump is small, and the first blocking member 341 and the second blocking member 343 cannot enter the position of the flexible portion 312. When the suction pump is working in a high-power state, the suction force of the suction pump is large, and the first blocking member 341 and the second blocking member 343 can smoothly enter the position of the flexible portion 312.

[0040] Specifically, before the oil suction pipe 31 needs to collect and process the oil inside the oil-water separation tank 1, the first blocking member 341 and the second blocking member 343 are located at the bottom of the second hard portion 313, because the combined first blocking member 341 and the second blocking member 343 just block the gap between the second hard portion 313 and the adjusting sleeve 36, and then the suction pump starts to work in a low-power mode. Under the suction of the suction pump in the low-power mode, the first blocking member 341 and the second blocking member 343 slide upward along the inner wall of the adjusting sleeve 36, and the first blocking member 341 and the second blocking member 343 move upward synchronously with the oil absorption cotton sleeve 342. At this time, the oil absorption cotton sleeve 342 gradually moves away from the bottom of the second hard portion 313, so that the oil absorption cotton sleeve 34 The bottom end of the second rigid part 313 is spaced apart from the bottom end of the oil-absorbing cotton sleeve 342, that is, there is a height difference between the bottom end of the oil-absorbing cotton sleeve 342 and the bottom end of the second rigid part 313. Subsequently, the linear telescopic part 35 drives the oil-absorbing pipe 31 to adjust the vertical position, so that the bottom end of the second rigid part 313 moves down to the boundary between the oil layer and the water layer inside the oil-water separation tank 1 (because there is a height difference between the bottom end of the oil-absorbing cotton sleeve 342 and the bottom end of the second rigid part 313, it is possible to prevent the oil-absorbing cotton sleeve 342 from contacting the oil layer inside the oil-water separation tank 1 in advance, and thus the oil-absorbing cotton sleeve 342 will not absorb the oil stains in the oil layer inside the oil-water separation tank 1 in advance, causing the oil-absorbing cotton sleeve 342 to reach a saturated state in advance, which is convenient for the oil-absorbing cotton sleeve 342 to absorb the oil on the inner wall of the oil-water separation tank 1 in the future). The suction pump then continues to operate in low power mode, and absorbs the oil above the oil-water separation tank 1. The absorbed oil enters the oil storage tank 2 through the oil suction pipe 31. At this time, residual oil is still adhered to the inner wall of the oil-water separation tank 1. The suction pump then stops working, and stops sucking the first blocking member 341 and the second blocking member 343. The suction pump then starts backwashing, and pushes the first blocking member 341 and the second blocking member 343 to slide along the inner wall of the adjusting sleeve 36 toward the water layer of the oil-water separation tank 1 through the airflow, until the first blocking member 341 and the second blocking member 343 move to the position of the limit block. At this time, the limit block blocks the first blocking member 341 and the second blocking member 343 to prevent the first blocking member 341 and the second blocking member 343 from being blocked. 1 and the second blocking member 343 are separated from the adjusting sleeve 36. Driven by the first blocking member 341 and the second blocking member 343, the oil absorbing cotton sleeve 342 is re-mounted on the outside of the second hard part 313 of the oil suction pipe 31. At this time, the bottom surface of the oil absorbing cotton sleeve 342 is flush with the bottom surface of the second hard part 313. After that, the driving shaft of the driving motor drives the connecting rod to rotate, and the connecting rod drives the linear telescopic part 35 and the oil suction pipe 31 to revolve as a whole. At this time, the oil suction pipe 31 rotates with the axis of the oil-water separation tank 1 as the center of the circle, driving the oil absorbing cotton sleeve 342 to move along the tank wall of the oil-water separation tank 1. The oil absorbing cotton sleeve 342 absorbs the oil stains adhered to the tank wall of the oil-water separation tank 1, and completes the collection and processing of the oil on the tank wall of the oil-water separation tank 1. Then the driving motor is temporarily stopped again.The suction pump works in a high-power state. Under the strong suction of the suction pump, the first blocking member 341 and the second blocking member 343 enter the adjusting section 361 along the sliding section 362 of the adjusting sleeve 36. When the first blocking member 341 and the second blocking member 343 slide along the adjusting section 361, because the inner wall of the adjusting section 361 tilts inward from bottom to top, as the first blocking member 341 and the second blocking member 343 slide from bottom to top on the adjusting section 361, the first blocking member 341 and the second blocking member 343 approach each other. At this time, the traction spring 345 connecting the first blocking member 341 and the second blocking member 343 is compressed, and the first blocking member 341 and the second blocking member 343 clamp the flexible portion 312 of the oil suction pipe 31, driving the first hard portion 311 and the second hard portion 312 to move. The flexible part 312 of the connecting channel between the first and second blocking parts 313 is closed, and then the high-power suction pump continues to work. Under the suction of the high-power suction pump, the oil-absorbing cotton sleeve 342 is tightly attached to the bottom surface of the first blocking part 341 and the second blocking part 343 under the suction of the suction pump. As the suction pump continues to suck, the oil absorbed by the oil-absorbing cotton sleeve 342 is pressed out by air pressure, and the pressed oil enters the inner cavity of the regulating sleeve 36 through the oil discharge holes 346 on the first blocking part 341 and the second blocking part 343, and enters the interior of the first hard part 311 along the connecting port 314 on the first hard part 311. The oil entering the interior of the first hard part 311 is transported into the oil storage tank 2 through the oil suction pipe 31, completing the removal of the oil inside the oil-water separation tank 1.

[0041] It should be noted that, in the present embodiment, the suction pump has two working modes, low power and high power, which is the prior art and will not be elaborated here.

[0042] In the above-mentioned embodiment, the oil stains absorbed by the oil-absorbing cotton sleeve 342 are completely extracted by wind pressure suction. In order to improve the oil extraction effect of the oil-absorbing cotton sleeve 342, in another embodiment of the present invention, a blocking filter plate 363 is also installed on the inner wall of the adjusting sleeve 36. The blocking filter plate 363 is located at the connection between the first hard portion 311 and the flexible portion 312. The blocking filter plate 363 is placed horizontally, and two vertical strips 364 are symmetrically installed on the side wall of the sliding section 362, wherein the strips 364 extend all the way to the position of the adjusting section 361 of the adjusting sleeve 36, wherein the two vertical strips 364 are both away from the inner wall of the oil-water separation tank 1, that is, as the oil suction pipe 31 rotates with the axis of the oil-water separation tank 1 as the center, the two strips 364 will not come into contact with the oil The inner wall of the water separation tank 1 is in contact, and the surfaces of the two long strips 364 close to the sliding section 362 are provided with sliding grooves 365, and the groove directions of the two sliding grooves 365 are parallel to the axial direction of the sliding section 362, and the two sliding grooves 365 are connected to the inner cavity of the adjusting sleeve 36, and sliders 366 are slidably installed in the two sliding grooves 365, and deflection baffles 367 are hinged on the two sliders 366, and torsion springs are connected between the two deflection baffles 367 and the sliders 366. It should be noted that when the torsion spring is not subjected to force and is in a natural state, the deflection baffle 367 is in a horizontal state; however, in the initial state, the slider 366 is located at the bottom of the long strip 364, and at this time, the slider 366 squeezes the deflection baffle 367, and the deformation of the torsion spring accumulates elastic potential energy, and at this time, the deflection baffle 367 is in a vertical state;As the slider 366 leaves the bottom of the strip 364 and moves upward, the deflection baffle 367 loses the squeeze of the slider 366, and the torsion spring releases the accumulated elastic potential energy, and the torsion spring drives the deflection baffle 367 to flip from the vertical state in the initial state to the horizontal state. At this time, the two deflection baffles 367 block the gap between the outer wall of the first hard part 311 and the inner wall of the adjusting sleeve 36, and the adjusting sleeve 36 is slidably connected to the oil suction pipe 31. The oil suction pipe 31 is provided with a trigger part 37, which is used to drive the adjusting sleeve 36 to move in the vertical direction away from the oil-water separation tank 1. The trigger part 37 includes two extension blocks 371, and the two extension blocks 371 are connected to the side walls of the blocking filter plate 363. The two extension blocks 371 correspond to the two strips 364 one by one. 1 are respectively inserted into the inside of the slide grooves 365 on the two long strips 364, and an air guide hole 372 is opened on the extension block 371. The axial direction of the air guide hole 372 is parallel to the axis of the blocking filter plate 363. Two rotating rings 373 are rotatably installed below the blocking filter plate 363. The axes of the two rotating rings 373 are parallel to the axis of the blocking filter plate 363. Shielding plates 374 are installed on the side walls of the two rotating rings 373. The two shielding plates 374 are respectively inserted into the slide grooves 365 of the two long strips 364. The two rotating rings 373 correspond to the first blocking member 341 and the second blocking member 343 respectively. A first wedge block 375 is installed below the two rotating rings 373, and a second wedge block 376 matching the first wedge block 375 is installed above the first blocking member 341 and the second blocking member 343. ;

[0043] Specifically, when the oil-absorbing cotton sleeve 342 has absorbed the oil stains on the inner wall of the oil-water separation tank 1, the suction pump works at a high power state, and the first blocking member 341 and the second blocking member 343 enter the adjustment section 361 along the sliding section 362 of the adjustment sleeve 36 under the strong suction of the suction pump. When the first blocking member 341 and the second blocking member 343 leave the bottom of the long strip 364 and move upward, the deflection baffle 367 loses the squeeze of the slider 366, and the torsion spring begins to release the accumulated elastic potential energy. The torsion spring drives the deflection baffle 367 to flip from the vertical state in the initial state to the horizontal state. At this time, the two deflection baffles 367 block the gap between the outer wall of the first hard part 311 and the inner wall of the adjustment sleeve 36, and the first blocking member 341 sliding upward The first and second blocking members 343 slide along the sliding section 362 of the adjusting sleeve 36 to the adjusting section 361 until the first and second blocking members 341 and 343 are blocked by the blocking filter plate 363. Since the inner wall of the adjusting section 361 is inclined inward from bottom to top, and since the inclination of the main sections on the first and second blocking members 341 and 343 is consistent with the inclination of the inner wall of the adjusting section 361, as the first and second blocking members 341 and 343 slide from bottom to top along the adjusting section 361, the first and second blocking members 341 and 343 approach each other. At this time, the traction spring 345 connecting the first and second blocking members 341 and 343 is compressed, and the first and second blocking members 341 and 343 make the flexibility of the oil suction pipe 31 The oil-absorbing cotton sleeve 342 is clamped by the part 312, driving the flexible part 312 serving as the connecting channel between the first hard part 311 and the second hard part 313 to close. When the oil-absorbing cotton sleeve 342 is tightly attached to the bottom surfaces of the first blocking member 341 and the second blocking member 343 under the suction of the suction pump, as the suction pump continues to suck, the oil absorbed by the oil-absorbing cotton sleeve 342 is pressed out by the air pressure, and the pressed oil enters the inner cavity of the regulating sleeve 36 through the oil discharge holes 346 on the first blocking member 341 and the second blocking member 343, and enters the interior of the first hard part 311 along the connecting port 314 on the first hard part 311, and when the first blocking member 341 and the second blocking member 343 gradually contact with the blocking filter plate 363, the first blocking member 341 The second wedge block 376 on the second blocking member 343 and the first wedge block 375 on the rotating ring 373 are squeezed against each other, driving the first wedge block 375 to drive the rotating ring 373 to rotate, and the rotating ring 373 moves away from the air guide hole 372 with the baffle plate 374, and the air guide hole 372 on the extension block 371 is opened. As the suction pump sucks at high power, the air flow attracts the slider 366 and the deflection baffle 367 through the air guide hole 372 on the extension block 371, so that the slider 366 moves along the slide groove 365 toward the first blocking member 341 and the second blocking member 343 until the deflection baffle 367 squeezes the oil-absorbing cotton sleeve 342 at the bottom of the first blocking member 341 and the second blocking member 343, and presses out the oil absorbed by the oil-absorbing cotton sleeve 342.Further improve the oil discharge efficiency of the oil absorbing cotton sleeve 342.

It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
