[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Example 1

[0028] Reference Figure 1-12 The present invention is a residue separation device for waste oil recovery, comprising a main tank body 1, a separation tank 2 is rotatably connected in the main tank body 1, a driving member for driving the separation tank 2 to rotate is fixedly connected to the main tank body 1; a residue outlet assembly is fixedly connected to the separation tank 2, and the residue outlet assembly includes a transmission mechanism, a plurality of U-shaped clamps 17 are staggered and fixedly connected to the transmission mechanism, a separation sleeve 18 is slidably connected in the U-shaped clamp 17, an interception filter cloth 21 is fixedly connected in the separation sleeve 18, a guide rod 19 is fixedly connected to the side of the separation sleeve 18, a plurality of special-shaped guide rails 22 are fixedly connected to the separation tank 2, the guide rod 19 is slidably matched with the special-shaped guide rail 22, the special-shaped guide rail 22 is divided into a smooth portion and a raised portion, and the raised portion is located outside the separation tank 2; The transmission mechanism includes a connecting frame 3, the connecting frame 3 is fixedly connected to the separation tank 2, a rotating shaft 4 is rotatably connected in the connecting frame 3, a second transmission roller 14 is fixedly connected to the side of the rotating shaft 4, a plurality of first transmission rollers 15 are rotatably connected in the separation tank 2, a guide belt 16 is transmission-connected between the first transmission roller 15 and the second transmission roller 14, a servo motor is fixedly connected to the side of the connecting frame 3, an output end of the servo motor is fixedly connected to the rotating shaft 4, and a U-shaped clamping plate 17 is fixedly connected to the guide belt 16; The cylindrical opening shell on the side of the separation tank 2 is the separation part, and the rest of the separation tank 2 is the oil storage part. Each group of connecting frames 3 corresponds to each separation part one by one. The driving part includes a cover top 23, and a driving motor 24 is fixedly connected to the surface of the cover top 23. A rotating sleeve 25 is rotatably connected to the bottom surface of the cover top 23. A liquid inlet pipe 27 is connected to the axial position of the separation tank 2, and a cross clamping rod 26 is fixedly connected to the end of the liquid inlet pipe 27. The rotating sleeve 25 is plugged into the cross clamping rod 26, and a cross clamping groove matched with the cross clamping rod 26 is provided in the rotating sleeve 25. A splash plate 20 is fixedly connected to the bottom surface of the separation sleeve 18.

[0029] The operation process of this embodiment is as follows: the waste oil to be recycled is input into the liquid inlet pipe 27, the waste oil enters the interior of the separation tank 2 through the liquid inlet pipe 27, the driving motor 24 drives the rotating sleeve 25 to rotate, and since the cross-cage slot provided in the rotating sleeve 25 is adapted to the cross-cage rod 26, the rotating sleeve 25 rotates to drive the liquid inlet pipe 27 to rotate, and the separation tank 2 rotates with the rotation of the liquid inlet pipe 27. The centrifugal force generated by the rotation of the separation tank 2 throws the solid particles in the waste oil in the oil storage part into the separation part, and the outer side of the separation part is an arc surface, that is, the separation tank 2 completes the solid-liquid separation at this time, and the residue is enriched at the separation part, so that the residue in the waste oil can be moved into the separation part to complete the solid-liquid separation, and the residue is enriched in the separation part, which is convenient for the user to remove the residue; The servo motor drives the rotating shaft 4 to rotate counterclockwise, and the rotating shaft 4 drives the second transmission roller 14 to rotate. The second transmission roller 14 cooperates with the first transmission roller 15 and the guide belt 16 to make the U-shaped clamping plate 17 on the guide belt 16 move continuously. The U-shaped clamping plate 17 and the separation sleeve 18 slide together, that is, as the rotating shaft 4 rotates continuously counterclockwise, the separation sleeve 18 on the U-shaped clamping plate 17 continuously picks up the residue in the separation part. The guide rod 19 on the separation sleeve 18 is slidably matched with the special-shaped guide rail 22. During the slag scooping process, the separation sleeve 18 is always in close contact with the U-shaped clamping plate 17 under the limitation of the special-shaped guide rail 22. After the separation sleeve 18 salvages the residue in the separation part, it continues to move following the movement of the guide belt 16. When the guide rod 19 on the separation sleeve 18 moves from the smooth part in the special-shaped guide rail 22 to the raised part, the separation sleeve 18 completes the flipping and moves out of the U-shaped clamping plate 17 at the raised part. At this time, the filter cloth is intercepted. 21 is located directly below the knocking rod 13 and away from the opening position of the separation part. After sticking and adsorbing the residue, the filter cloth can be turned over and away from the separation part, so that the residue in the separation tank 2 can be salvaged and separated from the oil and fall through the raised part of the special-shaped guide rail 22. The residue does not enter the separation tank 2, thereby improving the finished product quality of the recovered oil. The splash plate 20 is located on the outside of the separation sleeve 18, which can prevent part of the residue from being thrown out of the separation sleeve 18 when the separation sleeve 18 is turned over. Example 2

[0030] Although the shaped guide rail 22 can separate the residue in the separation tank 2 and make it fall out of the separation tank 2, in actual use, some residues will stick to the interception filter cloth 21 and it is difficult to fall off. Long-term use will cause the interception filter cloth 21 to be blocked. For this reason, please refer to Figure 8-11 On the basis of the specific embodiment 1, an oil residue separator is fixedly connected to the side of the separation tank 2, and the oil residue separator includes an L-shaped sleeve 6, the L-shaped sleeve 6 is fixedly connected to the separation tank 2, an extension plate 7 is fixedly connected to the side of the L-shaped sleeve 6, a linkage gear 8 is rotatably connected to the extension plate 7, a missing gear 5 is fixedly connected to the end of the rotating shaft 4, the linkage gear 8 and the missing gear 5 are meshed with each other, a slide rod 9 is slidably connected to the L-shaped sleeve 6, a baffle 10 is fixedly connected to the end of the slide rod 9, a spring 11 is fixedly connected between the baffle 10 and the L-shaped sleeve 6, a rack 12 is fixedly connected to the side of the baffle 10, the rack 12 is meshed with the linkage gear 8, and a knocking rod 13 is fixedly connected to the end of the rack 12, and the knocking rod 13 is used to knock off the sticky oil residue on the interception filter cloth 21.

[0031] The operation process of this embodiment is as follows: the residue of the separation part is continuously scooped up by multiple filter cloths. When the filter cloth removes the residue, the residue will adhere to the surface of the filter cloth and is difficult to remove. By rotating the rotating shaft 4 counterclockwise, the rotating shaft 4 drives the missing gear 5 to rotate counterclockwise. When the missing gear 5 is meshed with the linkage gear 8, it drives the linkage gear 8 to rotate clockwise. The linkage gear 8 rotates clockwise to drive the rack 12 to move upward. The rack 12 moves to pull the baffle 10 to move upward, and the spring 11 is stretched. The slide bar 9 moves upward in the L-shaped sleeve 6, and the stability of the movement of the rack 12 is improved. At this time, as the rack 12 gradually moves, the knocking rod 13 can be energy stored. As the missing gear 5 continues to rotate, when the teeth on the missing gear 5 are disengaged from the teeth on the linkage gear 8, the linkage gear 8 loses the limit of the missing gear 5, and the stretched spring 11 rebounds at this time, pulling the rack 12 to move downward quickly, knocking the filter cloth, knocking out the sticky residue on the filter cloth, and the knocked-out filter cloth re-enters the separation tank 2 to continue to salvage the residue. In the process of separating the residue from the oil, the filter cloth with the residue can be continuously knocked and cleaned, thereby preventing the residue on the filter cloth from gathering more and more during the solid-liquid separation process, and the separation effect of the residue in the waste oil is gradually weakened; When the rotating shaft 4 drives the guide belt 16 to move, the intercepting filter cloth 21 moves along the special-shaped guide rail 22, and the gear 5 also rotates with the rotation of the rotating shaft 4. Figure 8As shown, each time the interception filter screen is located at the top of the raised portion in the special-shaped guide rail 22, the teeth on the missing gear 5 just disengage from the teeth on the linkage gear 8, so that when the interception filter cloth 21 moves and passes through the top position of the raised portion of the special-shaped guide rail 22, the knocking rod 13 just completes one energy storage and knocks down the residue on the interception filter cloth 21. As the rotating shaft 4 continues to rotate, multiple groups of interception filter cloths 21 continue to salvage the residue at the separation position of the separation tank 2, and each time the interception filter screen flips over and passes through the raised portion of the special-shaped guide rail 22, the knocking rod 13 can knock down the residue sticking to its surface, thereby preventing the residue on the interception filter screen from gathering more and more and affecting the quality of the recovered oil product. Example 3

[0032] After the waste residue on the interception filter cloth 21 is knocked down, the residue is removed from the separation tank 2 and falls into the main tank body 1, which is not convenient for subsequent cleaning. Figure 1-12 On the basis of the specific embodiment 1, a plurality of liquid inlets 28 are provided on the side of the liquid inlet pipe 27, a connecting sleeve 29 is fixedly connected to the main tank body 1, the connecting sleeve 29 is rotatably matched with the liquid inlet pipe 27, and the opening of the connecting sleeve 29 is aligned with the liquid inlet 28; A cross stirring plate 30 is fixedly connected to the inner bottom surface of the separation tank 2, and an outlet 31 is opened at the axial position of the bottom of the cross stirring plate 30. A receiving plate 32 is fixedly connected to the surface of the separation tank 2, and a plurality of serpentine guide plates 33 are fixedly connected to the surface of the receiving plate 32. The serpentine guide plates 33 are arranged parallel to the separation sleeve 18. A knocking plate 36 is fixedly connected to the end of the knocking rod 13, and a plurality of knocking blocks 37 are evenly fixedly connected to the knocking plate 36. A support frame 34 is fixedly connected to the side surface of the main tank body 1, and a base 35 is fixedly connected to the side surface of the support frame 34.

[0033] The operation process of this embodiment is as follows: the knocking rod 13 knocks the intercepting filter downward after accumulating energy, the knocking rod 13 moves to drive the knocking plate 36 to move, and the knocking plate 36 moves to drive the multiple knocking blocks 37 to knock the residue sticking on the intercepting filter, which can improve the cleaning ability of the residue on the intercepting filter, and the main tank body 1 is supported by the support frame 34 and the base 35, thereby improving the stability of the device; When the residue particles fall from the interception filter, they just fall into the top of the serpentine guide plate 33, and the residue slides along the serpentine guide plate 33 into the receiving plate 32, which can facilitate the subsequent user to handle the residue. When the residue in the oil storage part is centrifuged to the separation part, the liquid inlet pipe 27 always keeps a rotating state. When adding waste oil to the separation tank 2, the oil is input into the connecting sleeve 29, and the oil enters the separation tank 2 through the connecting sleeve 29 and the liquid inlet 28, completing the addition of the oil; The cross stirring plate 30 can rotate along with the rotation of the separation tank 2, thereby enabling the oil in the separation tank 2 to rotate, thereby increasing the centrifugal force in the oil and accelerating the enrichment of the residue. After the residue in the oil is cleaned, the valve on the recovery pipe at the bottom of the separation tank 2 is opened, and the recovered oil can be discharged from the recovery pipe through the opening at the bottom of the cross stirring plate.

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, and they should be covered by the protection scope of the present invention.
