[0046] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0047] Example 1, as Figure 1-13 As shown, the present invention provides a waste mineral oil collection and filtering device, including a bottom frame 1, a filter cartridge 2 is fixedly mounted on the upper surface of the bottom frame 1, an oil pipe 3 is connected to the surface of the bottom frame 1, a filtering structure 4 is provided on the surface of the filter cartridge 2, a replacement structure 5 is provided on the surface of the bottom frame 1, and a winding structure 6 is provided on the surface of the bottom frame 1.

[0048] The specific settings and functions of the filtering structure 4, the replacement structure 5 and the winding structure 6 are described in detail below.

[0049] like Figure 1 - Figure 6 As shown, the filter structure 4 includes a filter element 41 having a filtering function and a limiting mechanism 42 that facilitates the flexible use of the filter element 41. The provision of the filter structure 4 facilitates the user to filter impurities in the waste mineral oil raw material, reduces the indiscriminate discharge of waste mineral oil, which not only pollutes the environment but also wastes resources, and maximizes the utilization rate of the waste mineral oil raw material.

[0050] The limiting mechanism 42 includes a fixed rod 421, which is fixedly connected to the side wall of the filter cartridge 2. The upper end of the fixed rod 421 is rotatably mounted with a rotating bar 422, and the side wall of the rotating bar 422 is fixedly mounted with a fixed frame 424. The inner wall of the fixed frame 424 is fixedly mounted with a hydraulic cylinder 423, and a hydraulic rod 425 is slidably mounted inside the hydraulic cylinder 423. The lower end of the hydraulic rod 425 is fixedly mounted with a rotating block 427, and the side wall of the rotating block 427 is rotatably mounted with a rotating pin rack 428. The surface of the rotating pin rack 428 is rotatably mounted with a fixed rack 426. The lower side of the fixed rack 426 is fixedly connected to the filter element 41. The filter element 41 includes an arc frame 412 with a semicircular ring structure in cross section and a filter plate 411. The filter plate 411 has a truncated cone structure. The waste mineral oil residue will slide along the slope of the filter plate 411 of the frustum structure to the inner wall of the arc frame 412, which facilitates the collection of filtered impurities and reduces the accumulation of filtered impurities on the filter plate 411 that affects the filtering efficiency. When the hydraulic cylinder 423 is started, the hydraulic rod 425 will drive the filter plate 411 to be removed from the inner wall of the filter cartridge 2, thereby realizing the flipping of the filter plate 411 and rotating the rotating bar 422 out from the upper side of the filter cartridge 2, which facilitates the regular dumping of impurities.

[0051] An acceleration mechanism 43 is provided on the lower surface of the filter plate 411. The acceleration mechanism 43 includes an acceleration mechanism 43 and a connecting frame 433 of the acceleration mechanism 43. The connecting frame 433 is fixedly connected to the lower surface of the filter plate 411. A servo motor 431 is fixedly mounted on the inner wall of the connecting frame 433. Two drive bars 432 are fixedly connected to the side wall of the output end of the servo motor 431. The drive bars 432 are parallel to the filter plate 411. When the servo motor 431 is started and waste mineral oil raw material is added to the filter cartridge 2, the servo motor 431 is started, and the servo motor 431 drives the drive bars 432 to rotate. The drive bars 432 and the waste mineral oil raw material on the filter plate 411 move relative to each other, thereby improving the efficiency of filtering the waste mineral oil raw material. Two rows of through-hole members 44 are fixedly mounted on the surface of the drive bar 432. These through-hole members 44 include coarse bristles 441, which are fixedly connected to the lower surface of the drive bar 432. The bristles 441 are arranged in pairs, forming an inverted "eight" configuration on the side away from the drive bar 432. Ball blocks 442 are fixedly connected to the ends of the bristles 441, and a number of barbs 443 are evenly fixedly connected to the sidewalls of the bristles 441. When the servo motor 431 is activated, the bristles 441 move relative to the inner walls of the filter holes on the filter plate 411, facilitating the removal of clogged filter holes. The curved ends of the bristles 441 facilitate insertion into the filter holes. The barbs 443 on the bristles 441 increase friction between the sidewalls of the bristles 441 and the filter holes, further improving the cleaning efficiency of the filter holes on the filter plate 411.

[0052] A locking mechanism 45 is provided on the surface of the fixing frame 426. The locking mechanism 45 includes a socket 453 provided on the surface of the fixing frame 426. A clamping bracket 451 is slidably mounted on the side wall of the rotating pin frame 428. The size of the clamping bracket 451 matches the size of the socket 453. A first spring 452 is fixedly mounted on the side where the clamping bracket 451 and the rotating pin frame 428 are adjacent to each other. When the clamping bracket 451 is released, the first spring 452 on the rotating pin frame 428 acts on the inner wall of the socket 453 to fasten the clamping bracket 451, thereby facilitating the quick locking of the filter plate 411 after rotation.

[0053] like Figure 1 and Figure 2 as well as Figure 7 - Figure 11As shown, the replacement structure 5 includes two limit frames 52, and the two limit frames 52 are fixedly installed on the side walls of the bottom frame 1. The interiors of the two limit frames 52 are threaded with screws 57, and the side walls of the two screws 57 are fixedly installed with baffles 58. The surfaces of the two screws 57 are covered with oil-water separation mesh rolls 51, and the inner wall of the bottom frame 1 is provided with two limit members 53, which include a rectangular plate 531. The rectangular plate 531 is fixedly connected to the inner wall of the bottom frame 1, and the side wall of the rectangular plate 531 is provided with a groove with a "Y"-shaped cross-section. The oil-water separation net provided on the inner wall of the bottom frame 1 can separate the oil and water in the filtered waste mineral oil, further improving the extraction purity of the waste mineral oil. When the oil-water separation net becomes damaged or clogged after long-term use, it needs to be replaced. The oil-water separation net roll 51 is placed between the two limiting frames 52, and the second bolt 65 is rotated and inserted into the inner wall of the oil-water separation net roll 51 to limit the oil-water separation net roll 51. The provision of the baffle 58 improves the precision of the limit of the oil-water separation net roll 51. Two sets of seals 55 are provided on the inner wall of the bottom frame 1. The seals 55 include two folding strips 552. The cross-section of the folding strips 552 is a wavy line structure. The seals 55 are glued to the sides of the two folding strips 552 that are close to each other, and the two seals 55 are in an open structure. The oil-water separation net is placed between the two sealing members 55. The provision of the folding strip 552 enhances the elastic effect of the sealing strip 551, further improving the sealing performance of the connection between the oil-water separation net. The open structure between the two sealing strips 551 facilitates the insertion of the oil-water separation net between the two sealing strips 551.

[0054] The side wall of the bottom frame 1 is provided with an anti-slip part 54, and the anti-slip part 54 includes an anti-slip frame 541. The anti-slip frame 541 is fixedly connected to the side wall of the bottom frame 1, and the side wall of the anti-slip frame 541 is evenly and fixedly connected with a number of arc-shaped thorns 542. The surface of the limit frame 52 is provided with a support member 56, and the support member 56 includes two limit grooves 561. The two limit grooves 561 are respectively opened on the surfaces of the two limit frames 52, and an inflection point is provided on the upper side of the limit groove 561. The inner walls of the two limit grooves 561 are slidably connected with a support bar 562, and both ends of the support bar 562 are fixedly installed with a stop pin 563. The oil-water separation net is sleeved on the inner wall of the reserved groove 532 on the two rectangular plates 531 to improve the stability of the oil-water separation net installed on the inner wall of the bottom frame 1. The oil-water separation net is sleeved on the surface of the arc-shaped thorns 542 on the anti-slip frame 541 to achieve the fixing of the oil-water separation net in a single-sided position. The support bar 562 is stuck on the upper side of the limit groove 561. The support bar 562 will achieve temporary support for the oil-water separation net, which facilitates the normal pulling of the oil-water separation net.

[0055] like Figure 1 、 Figure 2 and Figure 12 as well as Figure 13As shown, the winding structure 6 includes a positioning block 64, which is fixedly connected to the side wall of the bottom frame 1. A circular rod 67 is slidably mounted inside the positioning block 64, and a movable frame 66 is fixedly mounted on the upper end of the circular rod 67. A rotating shaft 63 is rotatably mounted inside the movable frame 66. A driving frame 62 is slidably mounted inside the movable frame 66. A second spring 68 is fixedly mounted on the side where the driving frame 62 and the movable frame 66 are close to each other. A first bolt 612 is threaded through the internal thread of the positioning block 64, and the first bolt 612 is rotatably connected to the internal structure of the movable frame 66. The other side of the oil-water separation net is wound around the rotating shaft 63, and the rotating shaft 63 is rotated to achieve the winding of the old and discarded oil-water separation net. At this time, the second bolt 65 is rotated, and the second bolt 65 will drive the wound oil-water separation net to move downward as a whole, facilitating the tightening of the oil-water separation net located on the inner wall of the bottom frame 1 and improving the use effect of the replaced oil-water separation net.

[0056] The interior of the drive frame 62 is provided with an anti-slip structure 61. The anti-slip structure 61 includes a limiting rod 613, which is slidably connected to the interior of the drive frame 62. An anti-slip plate 611 is fixedly mounted on the side of the limiting rod 613 away from the drive frame 62. The anti-slip plate 611 has a V-shaped cross-section, and two rows of arc-shaped spikes 614 are evenly fixedly mounted on the inner wall of the anti-slip plate 611. The spikes 614 are of an arc-shaped structure. The anti-slip plate 611 is pressed against the surface of the reeled exhaust gas oil-water separator net by the elastic force of a second spring 68 between the drive frame 62 and the movable frame 66. The provision of the arc-shaped spikes 542 reduces the possibility of the oil-water separator net slipping, thereby temporarily securing the reeled oil-water separator net. By rotating the first bolt 612, the distance between the drive frame 62 and the anti-slip plate 611 can be adjusted, thereby facilitating the positioning of oil-water separator nets of different reeling thicknesses.

[0057] Its overall working principle is as follows: when it is necessary to filter the waste mineral oil, the filter element 41 is sleeved on the inner wall of the filter cartridge 2, the servo motor 431 is started, the waste mineral oil raw material is put into the filter cartridge 2 and the servo motor 431 is started. The servo motor 431 will drive the driving bar 432 to rotate, and the driving bar 432 and the waste mineral oil raw material on the filter plate 411 will move relative to each other, thereby improving the efficiency of filtering the waste mineral oil raw material. The oil residue of the waste mineral oil raw material will slide along the slope of the filter plate 411 of the frustum structure to the inner wall of the arc frame 412, which is convenient for collecting filtered impurities and reducing the accumulation of filtered impurities on the filter plate 411 affecting the filtering efficiency. In the process of starting the servo motor 431, the coarse bristles 441 will move relative to the inner wall of the filter hole on the filter plate 411, which is convenient for through-hole cleaning of the filter hole at the blocked position, and the coarse bristles 441 are set to a structure with a bent end side, which is convenient for cleaning the coarse bristles 441 in the filter hole. The purlin 452 of the filter element 421 is pulled out of the filter housing 2 and the filter 411 is pulled out of the filter housing 2. The purlin 452 of the filter element 421 is pulled out of the filter housing 2 and the filter 411 is pulled out of the filter housing 2.

[0058] Arranging an oil-water separation net on the inner wall of the bottom frame 1 can realize the separation of oil and water in the waste mineral oil after filtration, further improving the extraction purity of the waste mineral oil. When the oil-water separation net is damaged or blocked after long-term use, it is necessary to replace the oil-water separation net. The oil-water separation net roll 51 is sleeved between the two limit frames 52, and the second bolt 65 is rotated and inserted into the inner wall of the oil-water separation net roll 51 to realize the limiting work of the oil-water separation net roll 51. The setting of the baffle 58 improves the accuracy of the limiting of the oil-water separation net roll 51. When the oil-water separation net needs to be replaced, the oil-water separation net on the oil-water separation net roll 51 is pulled and the oil-water separation net is sleeved between the two sealing members 55. The setting of the folding strip 552 enhances the elastic effect of the sealing strip 551, further improving the oil-water separation. The sealing of the mesh connection and the open structure between the two sealing strips 551 facilitate the insertion of the oil-water separation mesh between the two sealing strips 551. The oil-water separation mesh is inserted into the inner wall of the reserved groove 532 on the two rectangular plates 531 to improve the stability of the oil-water separation mesh installed on the inner wall of the bottom frame 1. The oil-water separation mesh is inserted into the surface of the arc-shaped thorns 542 on the anti-slip frame 541 to fix the oil-water separation mesh in a single-sided position. The support bar 562 is stuck on the upper side of the limiting groove 561. The support bar 562 will realize temporary support for the oil-water separation mesh, which facilitates the normal pulling of the oil-water separation mesh. By setting the replacement structure 5 and regularly replacing the oil-water separation mesh on the oil-water separation mesh roll 51, the efficiency of oil-water separation in waste mineral oil is improved to a certain extent, and the filtering effect of waste mineral oil is further improved.

[0059] The second bolt 65 is rotated at this time, and the second bolt 65 will drive the rolled oil-water separation net to move downward as a whole, facilitating the tightening of the oil-water separation net on the inner wall of the bottom frame 1, thereby improving the use effect of the replaced oil-water separation net. By setting the winding structure 6, the regular winding of the exhaust gas oil-water separation net is facilitated, and the replacement efficiency of the oil-water separation net is further improved.
