DETAILED DESCRIPTION

[0033] like Figures 1-10 As shown, a waste oil treatment and decolorization device and decolorization method includes a filter tower 1 and a filter assembly 703 arranged inside the filter tower 1. The filter assembly 703 can filter and decolorize the waste oil. The top and bottom ends of the filter tower 1 can be equipped with guide pipes to facilitate the introduction and export of oil. When actually used, the filter assembly 703 is filled in the cylinder 7. Figure 2 As described, a partition 4 is fixedly installed inside the filter tower 1, and a plurality of through holes 401 are evenly opened on the partition 4. The cylinder 7 is located below the partition 4 and aligned with the through holes 401, so that the waste oil passing through the through holes 401 can flow through the filter assembly 703, thereby completing the treatment of the waste oil.

[0034] In order to install the cylinder 7, a rotating shaft 5 is provided below the through hole 401. The rotating shaft 5 passes through the axis of the through hole 401. The rotating shaft 5 corresponds to the through hole 401 one by one. A slider 9 is provided on the rotating shaft 5 to match the cylinder 7. Figure 3 The figure shows the state in which one of the sliders 9 cooperates with the cylinder 7. Specifically, the cylinder 7 is inserted into the filter tower 1 through the bottom end of the filter tower 1, so that the cylinder 7 is connected to the slider 9. During the rotation of the rotating shaft 5, the slider 9 can be driven to move toward the direction close to the through hole 401, thereby driving the cylinder 7 to move to the bottom of the through hole 401.

[0035] Reference Figure 3-Figure 6 、 Figure 9As shown, a screw hole 901 is provided on the bottom surface of the slider 9, and a connecting rod 702 is provided at the center position of the cylinder 7. The connecting rod 702 passes through the cylinder 7 along the axial direction of the cylinder 7 and rotates with the cylinder 7 through a tapered roller bearing. An external thread is provided on the outer peripheral wall of the connecting rod 702 near the top, so that the top of the connecting rod 702 can be threadedly connected to the screw hole 901. A turntable is fixed at the bottom end of the connecting rod 702, which is conducive to driving the connecting rod 702 to rotate.

[0036] The slider 9 is provided with a threaded hole that matches the rotating shaft 5, so that the rotating shaft 5 passes through the threaded hole and is threadedly connected to the slider 9. Through this structure, when the rotating shaft 5 rotates, it can drive the slider 9 to move along the axial 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.

[0037] Reference Figure 2-Figure 6 、 Figure 11 As shown, in actual use, a guide cylinder 102 is fixedly provided in the inner cavity of the filter tower 1 and near the bottom end. 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 pushed toward the inner cavity 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, the process of rotating the connecting rod 702 can prompt the connecting rod 702 and the cylinder 7 to continue to move toward the inside of the filter tower 1, so that the cylinder 7 can be completely moved 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, the rotating shaft 5 can drive the cylinder 7 to move to the bottom of the through hole 401.

[0038] During actual use, when the slider 9 drives the cylinder 7 to move to the bottom of the through hole 401, space is left between the cylinder 7 and the partition 4, so that the waste oil can flow to the outside of the cylinder 7, which is not conducive to the treatment of the waste oil. Based on this, this solution is fixed with multiple main semi-rings 8 at the bottom of the partition 4. The main semi-rings 8 correspond one-to-one to the through hole 401 and the main semi-rings 8 are arranged on the outside of the through hole 401. Specifically, the main semi-rings 8 are coaxially arranged with the through hole 401, and a secondary semi-ring 701 that cooperates with the main semi-ring 8 is fixed at the top of the cylinder 7 and at the outer edge. When the main semi-ring 8 and the secondary semi-ring 701 are in contact, they can form a circular structure.

[0039] In actual use, the cylinder 7 is passed through the guide cylinder 102 so that the top of the connecting rod 702 can be threadedly connected to the screw hole 901. As the connecting rod 702 rotates, the cylinder 7 can gradually move upward and disengage from the guide cylinder 102. When the secondary semi-ring 701 at the top of the cylinder 7 contacts the bottom surface of the partition 4, the connecting rod 702 rotates into place. At this time, the staff can drive the slider 9 and the cylinder 7 threadedly connected to the slider 9 to move toward the direction close to the through hole 401 by rotating the rotating shaft 5. When the cylinder 7 moves to the through hole 40 1 and aligned with the through hole 401, the secondary half ring 701 can fit with the main half ring 8. At this time, the cooperation between the main half ring 8 and the secondary half ring 701 can block the space between the cylinder 7 and the partition 4, thereby preventing waste oil from flowing out from between the partition 4 and the cylinder 7. After one of the cylinders 7 is installed, the staff rotates the other rotating shaft 5 so that the slider 9 on the rotating shaft 5 moves to the center of the partition 4 to install the next cylinder 7. Repeating the above operation can install multiple cylinders 7 in the filter tower 1.

[0040] To sum up, this device is threadedly connected to the slider 9 through the connecting rod 702 and cooperates with the limit of the guide cylinder 102, so that the cylinder 7 can be stably docked under the slider 9, so that the cooperation between the rotating shaft 5 and the slider 9 can drive the cylinder 7 to move to the bottom of the through hole 401, and the cooperation between the secondary half ring 701 and the main half ring 8 can seal the space between the cylinder 7 and the partition 4, so that the waste oil can only flow out through the cylinder 7, so that the waste oil can be processed through the filter component 703 in the cylinder 7, which is more conducive to replacing the filter component 703 than the traditional decolorization device.

[0041] Reference Figures 1-6 As shown, a support frame 3 is provided at the filter tower 1, and a base 301 is fixedly provided on the top of the support frame 3, and a connecting shaft 101 is fixedly provided on the outer wall of the filter tower 1. The connecting shaft 101 passes through the base 301 and rotates with the base 301 through a bearing. A hydraulic rod 2 is also arranged on the outside of the filter tower 1. Specifically, hinge seats are fixedly provided on the outer wall of the filter tower 1 and the ground, so that the hydraulic rod 2 is hinged between the two hinge seats. Through this structure, the hydraulic rod 2 can drive the filter tower 1 to deflect. When the filter tower 1 deflects to an approximately horizontal state, it is convenient to insert the cylinder 7 into the inner cavity of the filter tower 1.

[0042] Reference Figure 1-Figure 5 As shown, the end of the rotating shaft 5 away from the slider 9 passes through the filter tower 1 and rotates with it through a sealed bearing. In 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 filter tower 1 to drive the rotating shaft 5 to rotate manually.

[0043] In the above structure, the end of the shaft 5 close to the slider 9 is in a suspended state. In order to improve the stability of the shaft 5, a slot 402 that matches the slider 9 is provided on the bottom surface of the partition 4. The side of the slider 9 close to the partition 4 is elastically connected to a block 902 that slides with the slot 402. The cross sections of the slot 402 and the block 902 are both Figure 8 The T-shaped structure shown in FIG. 4 has a guide port 4021 at one end of the slot 402 close to the through hole 401, so that the block 902 can be removed from the guide port 4021. Figure 2-Figure 6 As shown, a slanted block 10 is fixedly provided on the side wall of the guide outlet 4021. The side of the slanted block 10 away from the through hole 401 is a slanted structure. When the clamping block 902 moves along the clamping slot 402 to the slanted block 10, the slanted block 10 squeezes the clamping block 902 so that the clamping block 902 can be accommodated in the slider 9 and moved out of the clamping slot 402.

[0044] Furthermore, a boss 6 is fixedly provided 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 4. When the block 902 moves out of the slot 402, it can fit with the boss 6, thereby preventing the block 902 from popping out. Through this structure, when the shaft 5 drives the slider 9 away from the through hole 401, the block 902 can return to the slot 402; combined with Figure 10 As shown, a support plate 103 can be fixedly mounted on the outside of 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.

[0045] In the initial state, the block 902 is in the slot 402, which can prevent the end of the rotating shaft 5 close to the slider 9 from being in a suspended state, thereby helping to maintain the stability and strength of the rotating shaft 5. In the process of the rotating shaft 5 driving the slider 9 close to the through hole 401, the block 902 can be moved out from the guide outlet 4021 and be located under the boss 6. After the connecting rod 702 is screwed into the screw hole 901, the cylinder 7 can be located at the bottom of the support plate 103. Therefore, after the block 902 is separated from the slot 402, the cooperation between the cylinder 7 and the support plate 103 can also support one end of the rotating shaft 5, thereby maintaining the stability of the rotating shaft 5 during the entire use process.

[0046] Combine Figure 3-Figure 8As shown, a limit spring 11 is fixedly provided inside the slot 402 at a position away from the end face of the through hole 401, and an extrusion spring 12 is fixedly provided on the inner side of the main half ring 8. The extrusion spring 12 can be sleeved on the outside of the rotating shaft 5. When the rotating shaft 5 rotates forward and drives the cylinder 7 to move to the bottom of the through hole 401, the rotating shaft 5 and the slider 9 are disengaged and the slider 9 can compress the extrusion spring 12. During the reverse rotation of the rotating shaft 5, the pressure of the extrusion spring 12 on the slider 9 enables the slider 9 to re-engage with the rotating shaft 5. As the rotating shaft 5 rotates in the opposite direction, the slider 9 can be driven to move to the center position of the partition 4, which is conducive to the replacement of the cylinder 7. Moreover, when the slider 9 moves to the center position of the partition 4, the rotating shaft 5 and the slider 9 are disengaged and the slider 9 can compress the limit spring 11, which is conducive to the re-engagement of the slider 9 with the rotating shaft 5 in the later stage.

[0047] Combine Figure 2-Figure 6 As shown, in actual use, a through circular hole 704 can be opened on the secondary semi-ring 701. During the process of fitting the secondary semi-ring 701 and 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 surfaces of the secondary semi-ring 701, so that the secondary semi-ring 701 and the partition 4, as well as the secondary semi-ring 701 and the main semi-ring 8, fit tightly.

[0048] In actual use, a slot 801 compatible with the slider 9 can be opened on the main half ring 8, so that the slider 9 passes through the slot 801 and fits against the inner wall of the slot 801. In this structure, the above-mentioned extrusion spring 12 needs to be fixed to the inner wall of the filter tower 1. By setting the slot 801, when the slider 9 is longer, interference between the slider 9 and the main half ring 8 can be avoided.

[0049] Reference Figure 3-Figure 7 As shown, the slider 9 is provided with a slot 903 on the side close to the secondary half ring 701, and a rod 7011 is fixedly provided on the inner wall of the secondary half ring 701. During the process of inserting the cylinder 7 into the interior of the filter tower 1, the end of the rod 7011 away from the secondary half ring 701 can be inserted into the slot 903. This structure can maintain the stability of the secondary half ring 701 during movement, thereby facilitating the fit between the secondary half ring 701 and the main half ring 8.

[0050] Reference Figure 3 、 Figure 9As shown, the filter assembly 703 includes filled activated carbon and decolorizing sand and other materials, which is conducive to filtering, removing impurities and decolorizing the waste oil. The filter plates 13 are fixedly installed at both ends of the cylinder 7, and the connecting rod 702 passes through the filter plate 13 and rotates with it. Of course, the above-mentioned filler will not leak from the filter plate 13, and impurities in the waste oil can also be filtered through the filter plate 13.

[0051] Reference Figure 1 、 Figure 10-12 In the figure, a plurality of guide holes are evenly provided on the wall of the guide cylinder 102, which is conducive to guiding the waste oil out of the filter tower 1. The slider 9 is provided with a groove that slides with the block 902. A spring is fixed between the inner end surface of the groove and the block 902, and the block 902 can be completely retracted into the groove.
