Description

Technical Field

[0001] The present invention relates to the technical field of waste oil treatment devices, and particularly relates to a waste oil treatment decolorization device and a decolorization method. Background Art

[0002] Currently, after some oils (lubricating oil, hydraulic oil) are used, since they are in direct contact with mechanical rotating parts (gears, crankshafts) during use, there are metal chips or residues in the used oil, and the used grease is called waste oil in the industry.

[0003] Chinese Patent CN217567826U discloses a flipable waste oil purification, decolorization and filtration device. When replacing the filter material inside the tank body, just turn it over so that the flange at the bottom is horizontally parallel, fix the bottom of the pipe body with an iron rod. At this time, the flange chassis can be opened with tools, take the iron rod away and let the tank body return to the vertical direction. At this time, the useless filter material inside automatically flows out and is discharged outside.

[0004] The above device disassembles the flange at the bottom end of the tank body after turning the tank body into a horizontal state. After that, when the tank body turns into a vertical state, the filter material inside the tank body can be discharged. However, during the process of reloading the filter material, it is still necessary to gradually pour the filter material into the tank body through the top or bottom of the tank body, which is relatively inconvenient in operation. In summary, the above device still has room for improvement.

[0005] Therefore, it is necessary to provide a waste oil treatment decolorization device and a decolorization method to solve the above technical problems. Summary of the Invention

[0006] The purpose of the present invention is to provide a waste oil treatment decolorization device and a decolorization method to solve the problem that the existing device disassembles the flange at the bottom end of the tank body after turning the tank body into a horizontal state. After that, when the tank body turns into a vertical state, the filter material inside the tank body can be discharged. However, during the process of reloading the filter material, it is still necessary to gradually pour the filter material into the tank body through the top or bottom of the tank body, which is relatively inconvenient in operation as mentioned in the above background art.

[0007] Based on the above idea, the present invention provides the following technical solution: A waste oil treatment decolorization device includes a filtration tower and a filtration component disposed in the filtration tower and used for removing impurities from waste oil. The filtration component is filled in a cylinder body. A partition is fixedly arranged in the inner cavity of the filtration tower, and a plurality of through holes are evenly formed in the partition. The cylinder body is located below the partition and is aligned with the through holes. A rotating shaft is arranged below the through hole. A slider is threadedly connected to the rotating shaft. During the process of inserting the cylinder body into the interior of the filter tower, it can be docked with the slider. During the rotation of the rotating shaft, the slider can be driven to move towards the direction close to the through hole, so that the cylinder body at the bottom of the slider can move below the through hole and be aligned with the through hole.

[0008] As a further solution of the present invention: a threaded hole is provided on the bottom surface of the slider, and a connecting rod is arranged at the central position of the cylinder body. The top end of the connecting rod is threadedly connected to the threaded hole.

[0009] As a further solution of the present invention: a guiding cylinder is fixedly arranged at a position in the inner cavity of the filter tower and close to the bottom end. The cylinder body can be inserted into the filter tower through the guiding cylinder. Before the cylinder body moves out of the guiding cylinder, the top end of the connecting rod can move to the threaded hole, so that when the connecting rod rotates, the cylinder body can be promoted to move out of the guiding cylinder.

[0010] As a further solution of the present invention: a plurality of main semi-rings are fixedly arranged at the bottom of the partition plate. The main semi-rings correspond to the through holes one by one and are arranged outside the through holes. At the position of the outer edge of the top of the cylinder body, a sub-semi-ring that cooperates with the main semi-ring is fixedly arranged.

[0011] As a further solution of the present invention: a clamping groove that cooperates with the slider is provided on the bottom surface of the partition plate. A clamping block that is elastically connected to the side close to the partition plate and slidably cooperates with the clamping groove is provided on the slider. One end of the clamping groove close to the through hole is a lead-out port, so that the clamping block can move out from the lead-out port. An inclined block is fixedly arranged on the side wall of the lead-out port. When the clamping block moves along the clamping groove to the inclined block, the clamping block can be received into the slider and move out of the clamping groove through the extrusion of the inclined block on the clamping block.

[0012] As a further solution of the present invention: a convex platform is fixedly arranged on the inner wall of the through hole. When the clamping block moves out of the clamping groove, it can be attached to the convex platform.

[0013] As a further solution of the present invention: a support plate is fixedly sleeved outside the guiding cylinder. When the cylinder body moves out of the guiding cylinder, it can be located between the support plate and the slider.

[0014] As a further solution of the present invention: a support frame is arranged at the filter tower. A base is fixedly arranged at the top of the support frame. A connecting shaft is fixedly arranged on the outer wall of the filter tower. The connecting shaft passes through the base and is rotationally matched with the base through a bearing.

[0015] As a further solution of the present invention: a hydraulic rod is arranged outside the filter tower. The telescopic end of the hydraulic rod is hinged to the filter tower.

[0016] A method for decolorizing waste oil using the above waste oil treatment and decolorization device includes the following steps: introducing the waste oil into the filtration tower so that the waste oil passes through the through holes on the partition plate. When the waste oil passes through the cylinder body, the filtration components inside the cylinder body can filter impurities and decolorize the waste oil.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: Through the threaded connection between the connecting rod and the slider and the cooperation with the limit of the guiding cylinder, the cylinder body can be stably docked below the slider. Thus, the cooperation between the rotating shaft and the slider can drive the cylinder body to move below the through hole, and through the cooperation between the sub-semicircle and the main semi-circle, the space between the cylinder body and the partition plate can be blocked, enabling the waste oil to only flow out through the cylinder body. Therefore, the waste oil can be treated by the filtration components inside the cylinder body, which is more conducive to replacing the filtration components compared with traditional decolorization devices.

[0020] As Figures 1 - 10 shown, a waste oil treatment and decolorization device and decolorization method include a filter tower 1 and a filter component 703 arranged inside the filter tower 1. Through the arranged filter component 703, waste oil can be filtered and decolorized. Flow guide pipes can be installed at both the top and bottom of the filter tower 1, which is beneficial to the import and export of oil. During actual use, the filter component 703 is filled in the cylinder body 7. Refer to Figure 2 described, a partition plate 4 is fixedly arranged inside the filter tower 1. A plurality of through holes 401 are evenly opened on the partition plate 4. The cylinder body 7 is located below the partition plate 4 and is aligned with the through holes 401, so that the waste oil passing through the through holes 401 can flow through the filter component 703, thereby completing the treatment of the waste oil.

[0021] To install the cylinder body 7, a rotating shaft 5 is arranged below the through hole 401 in this solution. The rotating shaft 5 passes through the axis of the through hole 401, and the rotating shaft 5 corresponds to the through hole 401 one by one. A slide block 9 matched with the cylinder body 7 is arranged on the rotating shaft 5. Figure 3 shows the state where one of the slide blocks 9 is matched with the cylinder body 7. Specifically, the cylinder body 7 is inserted into the filter tower 1 through the bottom end of the filter tower 1, so that the cylinder body 7 is connected to the slide block 9. During the rotation of the rotating shaft 5, the slide block 9 can be driven to move towards the direction close to the through hole 401, thereby driving the cylinder body 7 to move below the through hole 401.

[0022] Refer to Figures 3 - 6 、 Figure 9 shown, a threaded hole 901 is opened on the bottom surface of the slide block 9, and a connecting rod 702 is arranged at the central position of the cylinder body 7. The connecting rod 702 penetrates through the cylinder body 7 along the axis direction of the cylinder body 7 and is rotationally matched with the cylinder body 7 through a tapered roller bearing. An external thread is arranged on the outer circumferential wall of the connecting rod 702 and close to the top end, so that the top end of the connecting rod 702 can be threadedly connected to the threaded hole 901. A turntable is fixedly arranged at the bottom end of the connecting rod 702, which is beneficial to driving the connecting rod 702 to rotate.

[0023] A threaded hole that mates with the rotating shaft 5 is provided on the slider 9, such that the rotating shaft 5 passes through the threaded hole and is threadedly connected to the slider 9. With this structure, when the rotating shaft 5 rotates, it can drive the slider 9 to move along the axis direction of the rotating shaft 5, thereby driving the slider 9 and the cylinder 7 threadedly connected to the bottom surface of the slider 9 to move to the through hole 401.

[0024] Refer to Figures 2 - 6 , Figure 11 As shown in the figure, during actual use, a guide cylinder 102 is fixedly arranged at a position near the bottom end inside the filter tower 1. The outer diameter of the above-mentioned cylinder 7 is slightly smaller than the inner diameter of the guide cylinder 102. During the installation process, the cylinder 7 is inserted into the guide cylinder 102 and the cylinder 7 is pushed towards the inside of the filter tower 1. Before the cylinder 7 moves out of the guide cylinder 102, the top end of the connecting rod 702 has moved to the screw hole 901. At this time, during the rotation of the connecting rod 702, it can prompt the connecting rod 702 and the cylinder 7 to continue to move towards the inside of the filter tower 1, so that the cylinder 7 can completely move out of the guide cylinder 102. Through the setting of the guide cylinder 102, the cylinder 7 can be stably docked with the slider 9, thereby improving the convenience of operation. After the slider 9 is docked with the cylinder 7, rotating the rotating shaft 5 can drive the cylinder 7 to move below the through hole 401.

[0025] During actual use, when the slider 9 drives the cylinder 7 to move below the through hole 401, there is a space between the cylinder 7 and the partition plate 4, enabling the waste oil to flow to the outside of the cylinder 7, which is not conducive to the treatment of the waste oil. Based on this, in this solution, a plurality of main semi-rings 8 are fixedly arranged at the bottom of the partition plate 4. The main semi-rings 8 correspond to the through holes 401 one by one and the main semi-rings 8 are arranged outside the through holes 401. Specifically, the main semi-rings 8 are coaxially arranged with the through holes 401, and a sub-semi-ring 701 that mates with the main semi-ring 8 is fixedly arranged at the position of the top of the cylinder 7 and on the outer edge. When the main semi-ring 8 and the sub-semi-ring 701 are in contact with each other, they can form a circular structure.

[0026] During actual use, the cylinder body 7 is passed through the guiding cylinder 102 so that the top end of the connecting rod 702 can be threadedly connected to the screw hole 901. As the connecting rod 702 rotates, the cylinder body 7 can gradually move upward and disengage from the guiding cylinder 102. When the secondary half-ring 701 at the top end of the cylinder body 7 contacts the bottom surface of the partition plate 4, the connecting rod 702 rotates in place. At this time, the staff can drive the slider 9 and the cylinder body 7 threadedly connected to the slider 9 to move towards the direction close to the through hole 401 by rotating the rotating shaft 5. When the cylinder body 7 moves below the through hole 401 and aligns with the through hole 401, the secondary half-ring 701 can fit with the main half-ring 8. At this time, the space between the cylinder body 7 and the partition plate 4 can be sealed through the cooperation of the main half-ring 8 and the secondary half-ring 701, thereby preventing waste oil from flowing out between the partition plate 4 and the cylinder body 7. After one cylinder body 7 is installed, the staff rotates another rotating shaft 5 to move the slider 9 on this rotating shaft 5 to the center of the partition plate 4, and then the next cylinder body 7 can be installed. Repeating the above operations can install multiple cylinder bodies 7 in the filtration tower 1.

[0027] In summary, this device makes the cylinder body 7 stably dock below the slider 9 through the threaded connection between the connecting rod 702 and the slider 9 and the limitation of the guiding cylinder 102. Thus, the cooperation between the rotating shaft 5 and the slider 9 can drive the cylinder body 7 to move below the through hole 401, and the space between the cylinder body 7 and the partition plate 4 can be sealed through the cooperation between the secondary half-ring 701 and the main half-ring 8, so that the waste oil can only flow out through the cylinder body 7. Therefore, the waste oil can be treated by the filtration component 703 in the cylinder body 7, which is more conducive to replacing the filtration component 703 compared with the traditional decolorization device.

[0028] Refer to Figures 1 - 6 As shown in the figure, a support frame 3 is provided at the filtration tower 1. A base 301 is fixedly provided at the top of the support frame 3, and a connecting shaft 101 is fixedly provided on the outer wall of the filtration tower 1. The connecting shaft 101 passes through the base 301 and is rotationally matched with the base 301 through a bearing. A hydraulic rod 2 is also arranged outside the filtration tower 1. Specifically, hinge seats are fixedly provided on both the outer wall of the filtration tower 1 and the ground, so that the hydraulic rod 2 is hinged between the two hinge seats. With this structure, the hydraulic rod 2 can drive the filtration tower 1 to deflect. When the filtration tower 1 deflects to an approximately horizontal state, it is beneficial to insert the cylinder body 7 into the inner cavity of the filtration tower 1.

[0029] Refer to Figures 1 - 5 As shown in the figure, the end of the rotating shaft 5 away from the slider 9 passes through the filtration tower 1 and is rotationally matched with it through a sealed bearing. During actual use, the rotating shaft 5 can be driven to rotate by a power mechanism such as a motor. Of course, a rocker can also be fixed at the end of the rotating shaft 5 passing through the filtration tower 1, and the rotating shaft 5 can be driven to rotate manually.

[0030] In the above structure, one end of the rotating shaft 5 close to the slider 9 is in a suspended state. To improve the stability of the rotating shaft 5, in this solution, a clamping groove 402 matching with the slider 9 is opened on the bottom surface of the partition plate 4. An elastic connecting block 902 that is slidably matched with the clamping groove 402 is connected to one side of the slider 9 close to the partition plate 4. The cross-sections of the clamping groove 402 and the block 902 are both Figure 8 the T-shaped structure shown. One end of the clamping groove 402 close to the through hole 401 is a lead-out port 4021, so that the block 902 can be removed from this lead-out port 4021. Combining Figures 2 - 6 as shown, an inclined block 10 is fixedly arranged on the side wall of the lead-out port 4021. The side of the inclined block 10 away from the through hole 401 is a slope structure. When the block 902 moves along the clamping groove 402 to the inclined block 10, the block 902 can be received into the slider 9 and removed from the clamping groove 402 by the extrusion of the inclined block 10 on the block 902; Further, a boss 6 is fixedly arranged on the inner wall of the through hole 401, and the bottom surface of the boss 6 is parallel to the bottom surface of the partition plate 4. When the block 902 is removed from the clamping groove 402, it can fit with the boss 6, so as to prevent the block 902 from popping out. Through this structure, when the rotating shaft 5 drives the slider 9 away from the through hole 401, the block 902 can return to the clamping groove 402 again; Combining Figure 10 as shown, a support plate 103 can be fixedly sleeved outside the guide cylinder 102. Of course, the support plate 103 can also be fixed between the guide cylinder 102 and the inner wall of the filter tower 1. The support plate 103 is a mesh plate structure, so that the filtered waste oil can pass through the support plate 103; In the initial state, the block 902 is in the clamping groove 402, which can prevent one end of the rotating shaft 5 close to the slider 9 from being in a suspended state, thus being beneficial to maintaining the stability and strength of the rotating shaft 5. When the rotating shaft 5 drives the slider 9 close to the through hole 401, the block 902 can be removed from the lead-out port 4021 and be under the boss 6. When the connecting rod 702 is screwed into the screw hole 901, the cylinder body 7 can be at the bottom of the support plate 103. Therefore, after the block 902 is separated from the clamping groove 402, the cooperation between the cylinder body 7 and the support plate 103 can also play a role in supporting one end of the rotating shaft 5, so as to maintain the stability of the rotating shaft 5 during the whole use process.

[0031] Combining Figures 3 - 8As shown in the figure, a limiting spring 11 is fixedly arranged inside the card slot 402 away from the end face of the through hole 401, and an extrusion spring 12 is fixedly arranged inside the inner side of the main semi-ring 8. The extrusion spring 12 can be sleeved outside the rotating shaft 5. When the rotating shaft 5 rotates forward to drive the cylinder body 7 to move to directly below the through hole 401, the rotating shaft 5 and the slider 9 are disengaged from meshing, and the slider 9 can compress the extrusion spring 12. During the reverse rotation of the rotating shaft 5, due to the pressure of the extrusion spring 12 on the slider 9, the slider 9 can be re-engaged with the rotating shaft 5. As the rotating shaft 5 rotates reversely, the slider 9 can be driven to move to the center position of the partition plate 4, which is beneficial to the replacement of the cylinder body 7. Moreover, when the slider 9 moves to the center position of the partition plate 4, the rotating shaft 5 and the slider 9 are disengaged from meshing, and the slider 9 can compress the limiting spring 11, which is beneficial to the re-engagement of the slider 9 and the rotating shaft 5 in the later stage.

[0032] Combined with Figures 2 - 6 As shown in the figure, during actual use, a through circular hole 704 can be opened on the secondary semi-ring 701. During the process of the secondary semi-ring 701 fitting with the main semi-ring 8, one end of the rotating shaft 5 can be inserted into the circular hole 704, thereby avoiding interference between the secondary semi-ring 701 and the rotating shaft 5. Of course, a rubber ring can be pasted on the inner wall of the circular hole 704 to improve the sealing performance between the rotating shaft 5 and the secondary semi-ring 701. Similarly, rubber strips can be pasted on the top surface and both end faces of the secondary semi-ring 701, so that the secondary semi-ring 701 fits tightly with the partition plate 4 and between the secondary semi-ring 701 and the main semi-ring 8.

[0033] During actual use, a notch 801 adapted to the slider 9 can also be opened on the main semi-ring 8, so that the slider 9 passes through the notch 801 and fits with the inner wall of the notch 801. In this structure, the above-mentioned extrusion spring 12 needs to be fixed on the inner wall of the filtration tower 1. Through the set notch 801, when the slider 9 is relatively long, interference between the slider 9 and the main semi-ring 8 can be avoided.

[0034] Referring to Figures 3 - 7 As shown in the figure, a slot 903 is opened on one side of the slider 9 close to the secondary semi-ring 701, and a plug rod 7011 is fixedly arranged on the inner wall of the secondary semi-ring 701. During the process of inserting the cylinder body 7 into the filtration tower 1, one end of the plug rod 7011 away from the secondary semi-ring 701 can be inserted into the slot 903. Through this structure, the stability of the secondary semi-ring 701 during movement can be maintained, which is beneficial to the fitting between the secondary semi-ring 701 and the main semi-ring 8.

[0035] Referring to Figure 3 、 Figure 9As shown, the filtering component 703 includes materials such as filled activated carbon and decolorizing sand, which is conducive to filtering and removing impurities and decolorizing waste oil. Filter plates 13 are fixedly installed at both ends of the cylinder body 7, and the connecting rod 702 passes through the filter plate 13 and is rotationally matched with it. Of course, the above-mentioned fillers will not leak out from the filter plate 13, and the filter plate 13 can also filter impurities in the waste oil.

[0036] Refer to Figure 1 、 Figures 10 - 12 In [reference], a plurality of diversion holes are evenly formed in the cylinder wall of the guide cylinder 102, which is conducive to guiding waste oil out of the filtration tower 1. A groove slidably matched with the block 902 is formed in the slider 9, and a spring is fixedly arranged between the inner end face of the groove and the block 902. The block 902 can be completely retracted into the groove.
