[0006] An oil removal system, comprising:

[0007] Wastewater container, hollow inside with an opening at the top;

[0008] The oil-adhesive strip is vertically arranged and joined end to end to form a ring structure. The lower part of the oil-adhesive strip extends into the interior of the wastewater container from the opening of the wastewater container.

[0009] A drive mechanism, connected to the oil-adhesive strip, is used to drive the oil-adhesive strip to rotate.

[0010] Furthermore, the drive mechanism includes:

[0011] support;

[0012] A drive disc is rotatably mounted above the wastewater container and has an annular groove on its side wall.

[0013] A drive motor is mounted on the bracket and connected to the drive disk, used to drive the drive disk to rotate;

[0014] The upper part of the oil-adhesive strip surrounds the drive disc on the inside and abuts against the side wall of the drive disc. When the drive disc rotates, the oil-adhesive strip rotates with the drive disc.

[0015] Furthermore, it also includes a protection mechanism, which includes a first stop and a second stop arranged at intervals, the first stop and the second stop being arranged along the axial direction of the drive disc, the oil-adhesive strip passing between the first stop and the second stop and abutting against the first stop and the second stop.

[0016] Furthermore, it also includes:

[0017] The oil scraping mechanism is mounted on the bracket;

[0018] A portion of the oil-adhesive strip passes through the oil-scraping mechanism. When the oil-adhesive strip rotates, the oil-scraping mechanism separates the oil adhering to the oil-adhesive strip from the oil-adhesive strip.

[0019] Furthermore, the oil scraping mechanism includes:

[0020] An oil collection box, connected to the bracket, has an open top.

[0021] The oil scraper is connected to the oil collection box. One end extends in the direction of the oil-adhesive strip and abuts against or leaves a gap with the oil-adhesive strip, while the other end extends into the interior of the oil collection box.

[0022] Furthermore, the oil collection box is provided with a vertical slot that penetrates the oil collection box, and the portion of the oil-adhesive strip passes through the slot;

[0023] The oil scraping components include a first oil scraping component and a second oil scraping component.

[0051] Example 1

[0052] like Figures 1 to 4As shown, the oil removal system of this utility model includes a wastewater container 1, an oil recovery container 2, and an oil removal device 3. The oil removal device 3 is used to separate the oil in the wastewater inside the wastewater container 1 from the wastewater, and send the separated oil into the oil recovery container 2 for recycling.

[0053] In this embodiment, the wastewater container 1 is a hollow, barrel-shaped structure. The top of the wastewater container 1 has an opening 11 that connects the interior of the wastewater container 1 to the outside air.

[0054] A drain pipe 12 is installed at the bottom of the side wall of the wastewater container 1, and the drain pipe 12 communicates with the interior of the wastewater container 1. The drain pipe 12 is sealed and fixed to the side wall of the wastewater container 1. The drain pipe 12 is used to discharge the water treated by the wastewater container 1.

[0055] An inlet pipe 13 is installed at the top of the side wall of the wastewater container 1. The inlet pipe 13 communicates with the interior of the wastewater container 1 and is sealed and fixed to the side wall of the wastewater container 1. The inlet pipe 13 is used to feed the wastewater to be treated into the interior of the wastewater container 1.

[0056] In this embodiment, the oil recovery container 2 is also a hollow barrel-shaped structure. The top of the oil recovery container 2 is provided with a connecting port 21, which connects the interior of the oil recovery container 2 with the outside air.

[0057] In this embodiment, the oil removal device 3 includes a support 31. The wastewater container 1 and the support 31 can be connected as one unit or be separately arranged. In this embodiment, the wastewater container 1 and the support 31 are separately arranged. A drive disk 32 is provided on the top side of the support 31 facing the direction of the wastewater container 1, and the drive disk 32 is rotatably arranged above the wastewater container 1. The side wall surface of the drive disk 32 has an annular groove.

[0058] In this embodiment, a drive motor 33 is mounted on the top of the bracket 31, and the drive motor 33 is fixed to the bracket 31 by bolts. The output shaft of the drive motor 33 faces the direction of the wastewater container 1. The drive disk 32 is fixed to the output shaft of the drive motor 33. The drive disk 32 and the output shaft of the drive motor 33 are coaxially arranged. When the drive motor 33 starts, the output shaft of the drive motor 33 drives the drive disk 32 to rotate clockwise.

[0059] In this embodiment, an oil-adhesive strip 34 is provided on the drive disc 32. The oil-adhesive strip 34 is made of steel. The ends of the oil-adhesive strip 34 are joined together to form a ring structure. The ring-shaped oil-adhesive strip 34 is vertically oriented. The upper part of the oil-adhesive strip 34 encloses the drive disc 32, and the inner side of the oil-adhesive strip 34 is in contact with the side wall of the drive disc 32. The lower part of the oil-adhesive strip 34 extends into the wastewater container 1 through the opening 11 at the top of the wastewater container 1. When the drive disc 32 rotates clockwise, the oil-adhesive strip 34 also rotates clockwise.

[0060] In this embodiment, the drive disk 32 includes a first disk body 321 and a second disk body 322 coaxially arranged, with a gap between the first disk body 321 and the second disk body 322. A connecting rod 323 is provided between the first disk body 321 and the second disk body 322, with a first end of the connecting rod 323 fixed to the first disk body 321 and a second end of the connecting rod 323 fixed to the second disk body 322.

[0061] Preferably, the first disc 321, the second disc 322, and the connecting rod 323 are coaxially arranged.

[0062] The diameter of the first disc 321 is the same as the diameter of the second disc 322. The diameter of the connecting rod 323 is smaller than the diameters of the first disc 321 and the second disc 322, thereby forming an annular groove between the first disc 321 and the second disc 322.

[0063] When the oil-adhesive tape 34 is connected to the drive disc 32, the first side region of the inner surface of the oil-adhesive tape 34 abuts against the first disc body 321, and the second side region abuts against the second disc body 322. The middle region of the inner surface of the oil-adhesive tape 34 aligns with the groove between the first disc body 321 and the second disc body 322. By aligning the middle region of the inner surface of the oil-adhesive tape 34 with the groove between the first disc body 321 and the second disc body 322, the oil adhering to the middle region of the inner surface of the oil-adhesive tape 34 will not stick to the drive disc 32, ensuring the oil carrying capacity of the inner surface of the oil-adhesive tape 34.

[0064] Preferably, a first rubber ring 3211 is provided on the first disc 321 and fitted onto the outside of the first disc 321. A second rubber ring 3221 is provided on the second disc 322 and fitted onto the outside of the second disc 322. By adding a first rubber ring 3211 to the first disc 321 and a second rubber ring 3221 to the second disc 322, when the oil-adhesive tape 34 is installed on the drive disc 32, the first rubber ring 3211 and the second rubber ring 3221 abut against the oil-adhesive tape 34, increasing the coefficient of friction between the drive disc 32 and the oil-adhesive tape 34. This makes it less likely for slippage to occur between the drive disc 32 and the oil-adhesive tape 34, ensuring that the oil-adhesive tape 34 can rotate with the drive disc 32 when it rotates.

[0065] Preferably, the first rubber ring 3211 is bonded and fixed to the first disc body 321. The second rubber ring 3221 is bonded and fixed to the second disc body 322.

[0066] When removing oil from the wastewater inside wastewater container 1, the lower part of the oil-adhesive strip 34 extends into the interior of the wastewater to be treated. Under the action of gravity, the inner side of the oil-adhesive strip 34 is tightly adhered to the drive disc 32. When the drive disc 32 rotates, the friction between the inner side of the oil-adhesive strip 34 and the side wall of the drive disc 32 causes the oil-adhesive strip 34 to rotate synchronously with the drive disc 32. As the oil-adhesive strip 34 rotates clockwise, the part of the oil-adhesive strip 34 that was originally inside the wastewater rotates out of the wastewater, and the oil floating on the surface of the wastewater adheres to the oil-adhesive strip 34. The part of the oil-adhesive strip 34 that was originally outside the wastewater rotates into the interior of the wastewater. As the oil-adhesive strip 34 continues to rotate, it continuously adheres and removes the oil floating on the surface of the wastewater, thus separating the oil from the wastewater.

[0067] In this embodiment, a protective mechanism 35 is also provided on the bracket 31. The protective mechanism 35 includes a horizontally arranged straight rod 351, the extension direction of which is parallel to the axis of the drive disk 32. The straight rod 351 is located below the drive disk 32. The first end of the straight rod 351 is fixedly connected to the bracket 31, and the second end of the straight rod 351 is a free end. The straight rod 351 is located outside the oil-adhesive strip 34 and is spaced apart from the oil-adhesive strip 34.

[0068] In this embodiment, a first stop 352 and a second stop 353 are provided on the side of the straight rod 351 facing the oil-adhesive strip 34, and the first stop 352 and the second stop 353 are arranged along the extending direction of the straight rod 351. Both the first stop 352 and the second stop 353 are fixedly connected to the straight rod 351. The first stop 352 and the second stop 353 are spaced apart, and the distance between the first stop 352 and the second stop 353 is sufficient to allow the oil-adhesive strip 34 to pass through.

[0069] The space between the first stop 352 and the second stop 353 is opposite to the oil-adhesive strip 34. The oil-adhesive strip 34 passes through the space between the first stop 352 and the second stop 353. The first stop 352 abuts against the side wall of the oil-adhesive strip 34 facing away from the bracket 31, and the second stop 353 abuts against the side wall of the oil-adhesive strip 34 facing the bracket 31.

[0070] When the oil-adhesive strip 34 is located on the drive disc 32, it passes between the first stop 352 and the second stop 353. The first stop 352 and the second stop 353 can restrict the movement direction of the oil-adhesive strip 34, preventing it from moving along the axial direction of the drive disc 32 and avoiding the situation where the oil-adhesive strip 34 detaches from the drive disc 32.

[0071] In this embodiment, an oil scraping mechanism 36 is fixed on the bracket 31. When the drive disc 32 drives the oil-adhesive strip 34 to rotate clockwise, the oil scraping mechanism 36 is located downstream of the drive disc 32, and the height of the oil scraping mechanism 36 is lower than the height of the drive disc 32. The oil scraping mechanism 36 includes an oil collection box 361 fixed on the bracket 31. The top of the oil collection box 361 is open. A groove 3611 recessed in the direction of the bracket 31 is provided on the side of the oil collection box 361 facing away from the bracket 31, and the groove 3611 extends vertically through the oil collection box 361. A portion of the oil-adhesive strip 34 passes vertically through the groove 3611.

[0072] Two oil scrapers, namely a first oil scraper 362 and a second oil scraper 363, are fixed on the oil collection box 361. The first oil scraper 362 and the second oil scraper 363 are located on both sides of the groove 3611. When a portion of the oil-adhesive strip 34 passes through the groove 3611, the first oil scraper 362 and the second oil scraper 363 clamp the oil-adhesive strip 34 in the middle. The width of both the first oil scraper 362 and the second oil scraper 363 is greater than the width of the oil-adhesive strip 34. When the first oil scraper 362 and the second oil scraper 363 are opposite to the oil-adhesive strip 34, both ends of the first oil scraper 362 and the second oil scraper 363 extend to the outer side of the oil-adhesive strip 34.

[0073] Preferably, both the first oil scraper 362 and the second oil scraper 363 are made of plastic. The plastic material of the first oil scraper 362 and the second oil scraper 363 has strong corrosion resistance and is less likely to damage the oil-adhesive strip 34.

[0074] In this embodiment, the first end of the first oil scraper 362 faces the inner side of the oil-adhesive strip 34, and the second end of the first oil scraper 362 extends into the interior of the oil collection box 361. The first oil scraper 362 is fixedly connected to the wall of the oil collection box 361. The height of the first end of the first oil scraper 362 is higher than the height of the second end of the first oil scraper 362, thereby making the first oil scraper 362 generally inclined.

[0075] The first end of the first oil scraper 362 abuts against or has a gap with the inner side of the oil-adhesive strip 34. The gap between the first end of the first oil scraper 362 and the oil-adhesive strip 34 prevents the oil adhering to the inner side of the oil-adhesive strip 34 from passing through. When the oil-adhesive strip 34 rotates clockwise, the first oil scraper 362 can scrape off the oil adhering to the inner side of the oil-adhesive strip 34, and the scraped oil flows along the first oil scraper 362 into the oil collection box 361.

[0076] In this embodiment, the first end of the second oil scraper 363 faces the outer side of the oil-adhesive strip 34, and the second end of the second oil scraper 363 extends into the interior of the oil collection box 361. The second oil scraper 363 is fixedly connected to the wall of the oil collection box 361. The height of the first end of the second oil scraper 363 is higher than the height of the second end of the second oil scraper 363, thereby making the second oil scraper 363 generally inclined.

[0077] The first end of the second oil scraper 363 abuts against or has a gap with the outer side of the oil-adhesive strip 34. The gap between the first end of the second oil scraper 363 and the outer side of the oil-adhesive strip 34 prevents the oil adhering to the outer side of the oil-adhesive strip 34 from passing through. When the oil-adhesive strip 34 rotates clockwise, the second oil scraper 363 can scrape off the oil adhering to the outer side of the oil-adhesive strip 34 and allow the scraped oil to flow along the second oil scraper 363 into the oil collection box 361.

[0078] In this embodiment, the oil recovery container 2 is lower than the oil collection box 361. An oil outlet pipe 4 is provided between the oil collection box 361 and the oil recovery container 2. The first end of the oil outlet pipe 4 penetrates the bottom wall of the oil collection box 361 and is connected to the interior of the oil collection box 361. The second end of the oil outlet pipe 4 extends into the interior of the oil recovery container 2 through the communication port 21 at the top of the oil recovery container 2. The oil outlet pipe 4 and the oil collection box 361 are sealed and fixed together. Oil entering the interior of the oil collection box 361 can flow along the oil outlet pipe 4 into the interior of the oil recovery container 2 for recovery.

[0079] Preferably, a shield 5 is also provided on the top of the bracket 31, which shields the drive disk 32 and the drive motor 33 from below. The shield 5 is fixedly connected to the bracket 31.

[0080] In other embodiments, the degreasing system further includes a timer and a control module, which are electrically connected to the drive motor 33. The timer controls the operating time of the drive motor 33. When the operating time of the drive motor 33 reaches the set time of the timer, the control module controls the drive motor 33 to stop by cutting off power. When the drive motor 33 stops, the oil-adhesive strip 34 also stops rotating.

[0081] After the oil-adhesive belt 34 has been running for a period of time, it is stopped. The oil-adhesive belt 34 ceases to agitate the wastewater inside the wastewater container 1, allowing the wastewater to settle for a period. During this settling process, the wastewater undergoes oil-water stratification, causing the oil to float on the surface. When the oil-adhesive belt 34 restarts, it can better adsorb the floating oil, thus separating the oil from the water.

[0082] Example 2

[0083] Reference Figure 5 as well as Figure 6 Embodiment 2, based on Embodiment 1, further includes a spray mechanism 6 in the oil removal system. The spray mechanism 6 can extract water from the wastewater container 1 and spray it to rinse the oil skimming mechanism 36. The spray mechanism 6 includes a spray head 61 fixed on a bracket 31, located above the oil collection box 361. The water outlet direction of the spray head 61 is towards the oil collection box 361.

[0084] The spraying mechanism 6 also includes a water pumping pipe 62. The first end of the water pumping pipe 62 penetrates the bottom of the side wall of the wastewater container 1, extending into the interior of the wastewater container 1. The second end of the water pumping pipe 62 is connected to the spray head 61. A pump device 63 is installed on the water pumping pipe 62, and the pump device 63 is connected to the interior of the water pumping pipe 62. The pump device 63 pumps wastewater from the wastewater container 1 and sends the wastewater along the water pumping pipe 62 into the spray head 61. The wastewater sent to the spray head 61 is sprayed out through the spray head 61 and sprays the oil collection box, the first oil scraper 362, and the second oil scraper 363.

[0085] Preferably, there are two spray heads 61. One spray head 61 has its water outlet direction facing the first oil scraper 362, and the other spray head 61 has its water outlet direction facing the second oil scraper 363. The second end of the water pumping pipe 62 is provided with two branch pipes 621. One branch pipe 621 is connected to one spray head 61, and the other branch pipe 621 is connected to the other spray head 61.

[0086] Wastewater is sprayed through spray head 61 to rinse the oil collection box 361, the first oil scraper 362, and the second oil scraper 363. After rinsing the oil collection box 361, the first oil scraper 362, and the second oil scraper 363 with wastewater, a small amount of treated water can be used to rinse the oil scraper mechanism 36 to collect the residual oil in the oil outlet pipe 4. This ensures that the treated oil is sent as far as possible into the oil recovery container 2, preventing the residual oil from solidifying in the oil outlet pipe 4 after a period of time and causing blockage.
