Description

Technical Field

[0001] This invention belongs to the field of landfill leachate treatment technology, and more specifically, relates to a device for efficient oil-water separation in landfill leachate treatment. Background Technology

[0002] Oily substances can hinder subsequent treatment of leachate, such as clogging filtration equipment or interfering with the biodegradation process, thus reducing treatment efficiency. Moreover, oil contains a large number of toxic and harmful substances, and direct discharge will seriously pollute soil and water bodies, damaging the ecological environment. Furthermore, some oil resources can be recovered after oil-water separation, realizing waste reuse, which is in line with the concept of circular economy.

[0003] The oil-water separators currently in use still have the following problems:

[0004] 1. Generally, there is a lack of movable oil collection structure, which makes it inconvenient to quickly separate oil from different locations in the landfill leachate pond; and the inner wall of the oil collection structure is prone to the adhesion of sediment and impurities, which is not conducive to the simultaneous discharge of sediment and impurities with the separated oil.

[0005] 2. When the oil inlet is large, debris on top of the landfill leachate can easily enter along with the oil; when the oil inlet is small, it is prone to blockage after long-term use, reducing the oil separation effect.

[0006] 3. The separated oil cannot be automatically connected to the external oil suction pump, which increases the processing time of the collected oil and is not conducive to efficient oil-water separation. Summary of the Invention

[0007] This disclosure relates to an efficient oil-water separation device for landfill leachate treatment, comprising a connection drive, an elastic suction section, an oil-water separation section, a multi-functional section, and an activity control section. When the multi-functional frame moves inward, it automatically scrapes the bottom inner wall of the plastic collection box, facilitating the simultaneous discharge of precipitated impurities along with the oil. The narrow rectangular oil inlet hole blocks debris from the top of the landfill leachate, improving the oil separation effect. Only when the L-shaped suction tube is accurately inserted into the plastic collection box will the oil in the plastic collection box enter the L-shaped suction tube. This solves the problems of precipitated impurities not being discharged simultaneously with the separated oil, debris from the top of the landfill leachate easily entering the oil along with it, and the inability of the separated oil to automatically connect with an external oil pump.

[0013] In at least some embodiments, the oil-water separation unit includes: an electric telescopic rod and a plastic collection box; the electric telescopic rod is fixedly installed at the bottom of the movable mounting base, and the electric telescopic rod is also electrically connected to the control panel; the plastic collection box is fixedly installed on the output shaft of the electric telescopic rod, and circular oil drain holes are respectively opened on the left and right sides of the plastic collection box, and four rectangular oil inlet holes are also opened on the plastic collection box.

[0014] In at least some embodiments, the oil-water separation unit further includes: a circular stabilizing rod and a powerful magnet A; there are two circular stabilizing rods, which are fixedly installed on the top of the plastic collection box, and the two circular stabilizing rods are also slidably connected to the movable mounting base; there are four powerful magnets A, which are fixedly installed on the plastic collection box.

[0015] In at least some embodiments, the multifunctional part includes: a circular mounting rod, a multifunctional frame, and a helical spring B; the circular mounting rod is fixedly installed inside the plastic collection box; there are two multifunctional frames, which are slidably installed outside the circular mounting rod, and the outer sides of the two multifunctional frames are in contact with the inner wall of the plastic collection box; the helical spring B is sleeved on the outside of the circular mounting rod, and the helical spring B is located between the two multifunctional frames.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. When the servo motor is working, the movable mounting base drives the electric telescopic rod and the plastic collection box to move left and right, which facilitates the treatment of oil in different positions in the landfill leachate; when the output shaft of the electric telescopic rod extends, the plastic collection box is slowly inserted into the landfill leachate containing oil. When the bottom rectangular oil inlet hole is lower than the oil at the top of the landfill leachate, the oil at the top of the landfill leachate can enter the plastic collection box through the bottom rectangular oil inlet hole, realizing automatic oil-water separation.

[0020] In addition, the two multi-functional racks seal the two circular oil drain holes, preventing the separated oil from flowing back into the landfill leachate through the two circular oil drain holes. When one of the L-shaped suction tubes is inserted into the plastic collection box, the corresponding multi-functional rack can move inward. On the one hand, the oil in the plastic collection box can enter the L-shaped suction tube through a circular arc suction groove, realizing the automatic discharge of the oil in the plastic collection box. On the other hand, when the multi-functional rack moves inward, it can automatically scrape the bottom of the inner wall of the plastic collection box, which is conducive to the discharge of impurities deposited in the plastic collection box along with the oil.

[0021] 2. In this invention, when the rectangular oil inlet is lower than the top of the plastic control cover, the plastic control cover can automatically seal the corresponding rectangular oil inlet, allowing the oil in the landfill leachate to enter the plastic collection box through the rectangular oil inlets at different heights, thus preventing the rectangular oil inlets from becoming clogged after prolonged use. At the same time, the narrower rectangular oil inlet blocks debris on top of the landfill leachate, improving the separation effect of the oil in the landfill leachate. When the output shaft of the electric telescopic rod is fully extended, the four strong magnets A and four strong magnets B come into contact, which limits the plastic control cover and ensures that the collected oil will not overflow through the rectangular oil inlet below.

[0022] In addition, when the oil in the plastic collection box is drained, the staff can fully retract the output shaft of the electric telescopic rod. At this time, the plastic collection box can also move upward a certain distance. When the output shaft of the electric telescopic rod is fully retracted, the two circular reset rods can push the plastic control cover downward, causing the four strong magnets A and four strong magnets B to separate. The plastic control cover will automatically slide downward under the action of gravity, realizing the automatic reset of the plastic control cover.

[0023] 3. When the L-shaped suction tube and the circular oil drain hole are not concentric, the plastic collection box can push the L-shaped suction tube outward. When the plastic collection box pushes the L-shaped suction tube outward, the connecting track can automatically press the control button. At this time, the control panel controls the servo motor to stop working. On the one hand, this avoids deformation of the L-shaped suction tube and the plastic collection box, ensuring their normal service life. On the other hand, it prevents the oil in the plastic collection box from flowing into the landfill leachate, ensuring that the oil in the plastic collection box enters the L-shaped suction tube only when the L-shaped suction tube is accurately inserted into the plastic collection box.

[0047] The oil-water separation unit 400 includes: an electric telescopic rod 401 and a plastic collection box 402; the electric telescopic rod 401 is fixedly installed at the bottom of the movable mounting base 102, and the electric telescopic rod 401 is also electrically connected to the control panel 200; the plastic collection box 402 is fixedly installed on the output shaft of the electric telescopic rod 401, and circular oil drain holes 4021 are respectively opened on the left and right sides of the plastic collection box 402, and four rectangular oil inlet holes 4022 are also opened on the plastic collection box 402; the oil-water separation unit 400 also includes: a circular stabilizing rod 403 and a powerful magnet A404; there are two circular stabilizing rods 403, and the two circular stabilizing rods 403 are fixedly installed on the top of the plastic collection box 402, and the two circular stabilizing rods 403 are also slidably connected to the movable mounting base 102; there are four powerful magnets A404, and the four powerful magnets A404 are fixedly installed on the plastic collection box 402;

[0048] The multi-functional unit 500 includes: a circular mounting rod 501, a multi-functional frame 502, and a helical spring B503; the circular mounting rod 501 is fixedly installed inside the plastic collection box 402; there are two multi-functional frames 502, and the two multi-functional frames 502 are slidably installed outside the circular mounting rod 501, and the outer sides of the two multi-functional frames 502 are in contact with the inner wall of the plastic collection box 402; the helical spring B503 is sleeved on the outside of the circular mounting rod 501, and the helical spring B503 is located between the two multi-functional frames 502;

[0049] Its specific function is as follows: Because the movable mounting base 102 is slidably mounted on the connecting rail 101, and the drive screw 104 is fixedly connected to the output shaft of the servo motor 103, and the drive screw 104 is also threadedly connected to the movable mounting base 102, when the servo motor 103 is working, the movable mounting base 102 drives the electric telescopic rod 401 and the plastic collection box 402 to move left and right, facilitating the handling of oil in different locations in the landfill leachate; wherein, when the servo motor 103 is working, the output shaft of the electric telescopic rod 401 needs to extend continuously and slowly; and because the plastic collection box 402 is fixedly mounted on... The output shaft of the electric telescopic rod 401 is fixedly mounted on the top of the plastic collection box 402, and the two circular stabilizing rods 403 are also slidably connected to the movable mounting base 102. When the output shaft of the electric telescopic rod 401 extends, the plastic collection box 402 is slowly inserted into the landfill leachate containing oil. When the bottom rectangular oil inlet hole 4022 is lower than the oil at the top of the landfill leachate, the oil at the top of the landfill leachate can enter the plastic collection box 402 through the bottom rectangular oil inlet hole 4022, thus realizing automatic oil-water separation.

[0050] Furthermore, since the two multi-functional racks 502 are slidably installed on the outside of the circular mounting rod 501, and the outer sides of the two multi-functional racks 502 are in contact with the inner wall of the plastic collection box 402, and the helical spring B503 is located between the two multi-functional racks 502, it plays a sealing role for the two circular oil drain holes 4021, preventing the separated oil from flowing back into the landfill leachate through the two circular oil drain holes 4021; when one of the L-shaped suction tubes 304 is inserted into the plastic collection box 402, the corresponding multi-functional rack 502 can move inward. On the one hand, the oil in the plastic collection box 402 can enter the L-shaped suction tube 304 through a ring of arc-shaped suction groove 3041, realizing the automatic discharge of the oil in the plastic collection box 402. On the other hand, when the multi-functional rack 502 moves inward, it can automatically scrape the bottom side of the inner wall of the plastic collection box 402, which is conducive to the discharge of the precipitated impurities in the plastic collection box 402 along with the oil.

[0051] In this embodiment of the disclosure, such as Figure 9 and Figure 10As shown, the activity control unit 600 includes: a U-shaped frame 601, a plastic control cover 602, and steel wire ropes 603; two U-shaped frames 601 are provided, and the two U-shaped frames 601 are fixedly installed on the left and right sides of the movable mounting base 102; the plastic control cover 602 is slidably installed on the outer wall of the plastic collection box 402; four steel wire ropes 603 are provided, and the four steel wire ropes 603 are fixedly installed on the two U-shaped frames 601 and the plastic control cover 602; the activity control unit 600 also includes: a strong magnet B604 and a circular reset rod 605; four strong magnets B604 are provided, and the four strong magnets B604 are fixedly installed on the plastic control cover 602; two circular reset rods 605 are provided, and the two circular reset rods 605 are fixedly installed on the bottom of the two U-shaped frames 601;

[0052] Its specific function is as follows: Since the two U-shaped frames 601 are fixedly installed on the left and right sides of the movable mounting base 102, and the plastic control cover 602 is slidably installed on the outer wall of the plastic collection box 402, and four steel wire ropes 603 are fixedly installed on the two U-shaped frames 601 and the plastic control cover 602, when the rectangular oil inlet 4022 is lower than the top of the plastic control cover 602, the plastic control cover 602 can automatically seal the corresponding rectangular oil inlet 4022, so that the oil in the landfill leachate can enter the plastic collection box 402 through the rectangular oil inlet 4022 at different heights, avoiding the rectangular oil inlet 4022 from being sealed for a long time. After use, blockage occurs. At the same time, the narrow rectangular oil inlet 4022 blocks the debris on the top of the landfill leachate, improving the separation effect of oil in the landfill leachate. Also, because four strong magnets A404 are fixedly installed on the plastic collection box 402 and four strong magnets B604 are fixedly installed on the plastic control cover 602, when the output shaft of the electric telescopic rod 401 is fully extended, the four strong magnets A404 and four strong magnets B604 just come into contact, which limits the plastic control cover 602 and ensures that the collected oil will not overflow through the rectangular oil inlet 4022 below.

[0053] Furthermore, since the two circular reset rods 605 are fixedly installed at the bottom of the two U-shaped frames 601, when the oil in the plastic collection box 402 is discharged, the operator can fully retract the output shaft of the electric telescopic rod 401. At this time, the plastic collection box 402 can also move upward a certain distance. When the output shaft of the electric telescopic rod 401 is fully retracted, the two circular reset rods 605 can push the plastic control cover 602 downward, causing the four powerful magnets A404 to separate from the four powerful magnets B604. Under the action of gravity, the plastic control cover 602 automatically slides downward, realizing the automatic reset of the plastic control cover 602.

[0054] In this embodiment of the disclosure, such as Figure 3 and Figure 5As shown, the elastic suction unit 300 includes: a circular mounting shaft 301, a movable mounting bracket 302, and a positioning retaining ring 303; two circular mounting shafts 301 are provided, and the two circular mounting shafts 301 are fixedly mounted on the connecting rail 101; the movable mounting bracket 302 is slidably mounted on the outside of the two circular mounting shafts 301; two positioning retaining rings 303 are provided, and the two positioning retaining rings 303 are fixedly mounted on the inner ends of the two circular mounting shafts 301; the elastic suction unit 300 also includes: an L-shaped suction tube 304, a helical spring A305, and a control button 306; the L-shaped... The suction tube 304 is fixedly installed on the movable mounting bracket 302, and an arc-shaped suction groove 3041 is opened at the inner end of the L-shaped suction tube 304. The L-shaped suction tube 304 is connected to the external oil pump. There are two helical springs A305, and the two helical springs A305 are sleeved on the outside of the two circular mounting shafts 301. The two helical springs A305 are located between the connecting rail 101 and the movable mounting bracket 302. The control button 306 is fixedly installed on the outside of the movable mounting bracket 302, and the control button 306 is also electrically connected to the control panel 200.

[0055] Its specific function is as follows: Because the movable mounting bracket 302 is slidably mounted on the outside of the two circular mounting shafts 301, and the two helical springs A305 are sleeved on the outside of the two circular mounting shafts 301, and the two helical springs A305 are located between the connecting rail 101 and the movable mounting bracket 302, when the L-shaped suction tube 304 is not concentric with the circular oil drain hole 4021, the plastic collection box 402 can push the L-shaped suction tube 304 to move outward; and because the control button 306 is fixedly mounted on the outside of the movable mounting bracket 302, and the control button 306 is also electrically connected to the control panel 200, when the plastic collection box 402... 2. When the L-shaped suction tube 304 is pushed outward, the connecting rail 101 can automatically press the control button 306. At this time, the control panel 200 controls the servo motor 103 to stop working. On the one hand, this avoids deformation of the L-shaped suction tube 304 and the plastic collection box 402, ensuring their normal service life. On the other hand, it prevents the oil in the plastic collection box 402 from flowing into the landfill leachate. Only when the L-shaped suction tube 304 is accurately inserted into the plastic collection box 402 will the oil in the plastic collection box 402 enter the L-shaped suction tube 304.

[0056] The specific usage and function of this embodiment are as follows:

[0057] In use, the operator first connects the connecting rail 101 to the landfill leachate tank using bolts. Then, the two L-shaped suction pipes 304 are connected to an external oil pump via hoses. Next, the control panel 200 is connected to an external power source. To separate the oil and water in the landfill leachate, the electric telescopic rod 401 is activated, causing the plastic collection box 402 to slowly insert into the oil-containing landfill leachate. When the bottom rectangular oil inlet hole 4022 is lower than the oil at the top of the landfill leachate, the oil at the top of the leachate can enter the plastic collection box 402 through the bottom rectangular oil inlet hole 4022, achieving automatic oil-water separation. Then, the servo motor 103 is activated. The two multi-functional brackets 502 seal the two circular oil drain holes 4021, preventing the separated oil from flowing back into the landfill leachate through the two circular oil drain holes 4021. When the servo motor 103 is working, the movable bracket... The mounting base 102 drives the electric telescopic rod 401 and the plastic collection box 402 to move left and right, facilitating the processing of oil in different locations in the landfill leachate. When the rectangular oil inlet 4022 is lower than the top of the plastic control cover 602, the plastic control cover 602 can automatically seal the corresponding rectangular oil inlet 4022, allowing the oil in the landfill leachate to enter the plastic collection box 402 through the rectangular oil inlet 4022 at different heights, preventing the rectangular oil inlet 4022 from becoming clogged after long-term use. At the same time, the narrower rectangular oil inlet 4022 blocks debris on the top of the landfill leachate, improving the separation effect of oil in the landfill leachate. When the output shaft of the electric telescopic rod 401 is fully extended, the four strong magnets A404 and B604 come into contact, which limits the plastic control cover 602, ensuring that the collected oil will not overflow through the rectangular oil inlet 4022 below.

[0058] When the L-shaped suction tube 304 is not concentric with the circular oil drain hole 4021, the plastic collection box 402 can push the L-shaped suction tube 304 outward. When the plastic collection box 402 pushes the L-shaped suction tube 304 outward, the connecting rail 101 can automatically press the control button 306. At this time, the control panel 200 controls the servo motor 103 to stop working. On the one hand, this avoids deformation of the L-shaped suction tube 304 and the plastic collection box 402, ensuring their normal service life. On the other hand, it prevents the oil in the plastic collection box 402 from flowing into the landfill leachate. Only when the L-shaped suction tube 304 is accurately inserted into the plastic collection box 402 will the oil in the plastic collection box 402 enter the L-shaped suction tube 304. In the L-shaped suction tube 304, when the L-shaped suction tube 304 is inserted into the plastic collection box 402, the external oil suction pump is activated; when one of the L-shaped suction tubes 304 is inserted into the plastic collection box 402, the corresponding multi-functional frame 502 can move inward. On the one hand, the oil in the plastic collection box 402 can enter the L-shaped suction tube 304 through a circular arc suction groove 3041, realizing the automatic discharge of the oil in the plastic collection box 402. On the other hand, when the multi-functional frame 502 moves inward, it can automatically scrape the bottom of the inner wall of the plastic collection box 402, which is conducive to the discharge of impurities deposited in the plastic collection box 402 along with the oil; after the oil in the plastic collection box 402 is discharged, the L-shaped suction tube 304 is separated from the plastic collection box 402.

[0059] When the output shaft of the electric telescopic rod 401 is fully retracted, the plastic collection box 402 can still move upward a certain distance. When the output shaft of the electric telescopic rod 401 is fully retracted, the two circular reset rods 605 can push the plastic control cover 602 downward, causing the four powerful magnets A404 to separate from the four powerful magnets B604. Under the action of gravity, the plastic control cover 602 automatically slides downward, realizing the automatic reset of the plastic control cover 602.
