However, in existing decolorization filter devices, the mixing mechanism used for stirring after adding the decolorizing agent is prone to damage after prolonged use, and the overall replacement and maintenance operation is quite troublesome. There is a lack of suitable individual replacement stirring rod mechanisms, and the opening and closing of the cover plate during the disassembly and assembly of the stirring rod mechanism is also quite troublesome. There is also a lack of suitable quick maintenance mechanisms. In addition, the discharge filter screen is prone to clogging after prolonged use, affecting the discharge effect, and the disassembly and cleaning of the filter screen is quite troublesome.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, the present invention provides a lubricating oil decolorization and filtration device, which has the following beneficial effects:

[0015] 1. Through the design of the mounting shell, this device achieves quick assembly and disassembly of the mounting shell and the rotating shaft via an innovative locking structure (groove, locking rod, locking ring). This design allows the stirring component to be disassembled as a single module, greatly facilitating users to individually inspect or replace the severely worn mounting shell with its own stirring rod. This avoids the hassle of complex operations requiring downtime or even replacement of the entire stirring shaft when replacing traditional welded or bolt-fixed stirring blades, significantly reducing maintenance costs and time.

[0016] 2. The inspection plate is designed with a hinged structure and a locking mechanism consisting of a locking rod, an adjusting plate, and a threaded adjusting rod. This structure makes it easy and quick to open the inspection plate for internal tank maintenance, while when closing, the locking rod can be firmly inserted into the locking hole by rotating the adjusting rod, thus ensuring that the inspection plate is tightly closed with the tank body, facilitating quick opening and closing and convenient internal maintenance operations.

[0017] 3. Through the design of the filter screen, the filter screen in the filtration mechanism is fixed in place by the cooperation of the mounting plate and the mounting groove with bolts. This design makes the filter screen an independent, quick-removable module. When the filter screen becomes clogged with impurities due to prolonged use and needs cleaning or replacement, the operator only needs to loosen a few bolts to remove the entire filter screen from the filter box for cleaning, greatly simplifying the maintenance process, reducing equipment downtime for cleaning, and ensuring filtration efficiency and production continuity.

[0028] Please see Figures 1-4 A lubricating oil decolorization and filtration device includes a tank body 1. Support legs 2 are provided on the lower end face of the tank body 1, with multiple support legs 2 arranged circumferentially relative to the tank body 1. A feed funnel 3 penetrates the front side of the upper end face of the tank body 1. A rotating shaft 4 is rotatably mounted on the tank body 1, with a stirring motor 5 connected to the bottom end of the rotating shaft 4. A guide pipe 6 penetrates the right side of the lower end face of the tank body 1, with a valve 7 mounted on the guide pipe 6. A filter mechanism is connected to the outer end of the guide pipe 6. Inspection plates 8 are hinged to both the left and right sides of the upper end face of the tank body 1. A mounting plate is detachably mounted on the rotating shaft 4. There are two symmetrically arranged housings 9. The inner walls of the two housings 9 are symmetrically provided with mounting blocks 10. The rotating shaft 4 is provided with grooves 11 corresponding to the two mounting blocks 10. The upper end face of the rotating shaft 4 is provided with through holes 12. The through holes 12 on the same side are connected to the two grooves 11. The locking rods 13 can be detachably installed inside the two through holes 12. The multiple mounting blocks 10 are provided with locking holes 14 corresponding to the locking rods 13. The upper ends of the two locking rods 13 are connected with locking rings 15. The locking rings 15 and the rotating shaft 4 are detachably installed.

[0029] In this embodiment, after prolonged use, the stirring rod on the mounting shell 9 is severely worn. The mounting shell 9 with the stirring rod is disassembled and replaced separately. After opening the hinged inspection plate 8, the locking ring 15 and locking rod 13 are removed from the rotating shaft 4. The mounting shells 9 on both sides are taken out from the positions of the opened inspection plates 8 on both sides. The new mounting shell 9 is inserted into the tank 1. The mounting block 10 is inserted into the groove 11 for positioning. The locking ring 15 and locking rod 13 are installed in accordance with the rotating shaft 4. The locking rod 13 is inserted into the through hole 12 and the locking hole 14 to lock the installation, which is convenient for individual disassembly and replacement.

[0030] More specifically, the lubricating oil to be decolorized and filtered is added into the tank 1 through the feed funnel 3. An appropriate amount of decolorizing agent is added into the tank through the feed funnel 3. The control device has its own control system and starts the stirring motor 5. The stirring motor 5 is fixedly installed at the bottom of the tank 1 by its own L-shaped plate. The stirring motor 5 drives the rotating shaft 4 to rotate, so that the mounting shell 9 with the stirring rod rotates and stirs as a whole, achieving efficient internal stirring and improving the decolorization efficiency. After the decolorization is completed, the valve 7 of the feed pipe 6 is opened to send the lubricating oil into the filtration mechanism for filtration and discharge.

[0031] Please see Figure 1 and Figure 2 As one implementation of the rotating shaft 4: the rotating shaft 4 is provided with sealed bearings 16 at both the upper and lower ends of the tank body 1.

[0032] Specifically, the sealed bearing 16 provides rotational sealing protection at the mating position of the rotating shaft 4 and the tank body 1.

[0033] Please see Figures 1-3 As one embodiment of the installation of the locking ring 15: the locking ring 15 is provided with a first connecting hole 17, and the top end of the rotating shaft 4 is provided with a second connecting hole 18 corresponding to the first connecting hole 17. The first connecting hole 17 and the second connecting hole 18 are connected by bolts.

[0034] Specifically, after the locking rod 13 is inserted to the bottom, the bolt passes through the first connecting hole 17 on the locking ring 15 and the second connecting hole 18 on the rotating shaft 4 and is tightened and fixed.

[0035] Please see Figure 1 and Figure 6 As one embodiment of material filtration: the filtration mechanism includes a filter box 19, a filter screen 20, and a discharge pipe 21. The filter box 19 and the guide pipe 6 are connected. The filter screen 20 is detachably installed inside the filter box 19. The upper end face of the filter screen 20 is provided with a mounting plate 22. The upper end face of the filter box 19 is provided with a mounting groove 23 corresponding to the mounting plate 22. The discharge pipe 21 is provided through the right end of the filter box 19. The mounting plate 22 is symmetrically provided with first mounting holes 24. The inner wall of the mounting groove 23 is provided with second mounting holes 25 corresponding to the two first mounting holes 24. The first mounting holes 24 and the second mounting holes 25 are connected by bolts.

[0036] Specifically, after the valve 7 of the feed pipe 6 is opened, the lubricating oil that has undergone internal decolorization is filtered through the filter screen 20 inside the filter box 19 and discharged out through the discharge pipe 21. After long-term use, the bolts between the first mounting hole 24 and the second mounting hole 25 are removed, and the filter screen 20 with the mounting plate 22 is disassembled. After the filter screen 20 is disassembled and cleaned, the filter screen 20 with the mounting plate 22 is installed in the mounting groove 23 of the filter box 19, the first mounting hole 24 and the second mounting hole 25 are aligned, and the bolts are passed through and tightened to fix it.

[0037] Please see Figure 1 , Figure 2 and Figure 5 As one implementation of the inspection plate 8: two inspection plates 8 are symmetrically provided with locking rods 26, and the tank body 1 is provided with locking holes 27 corresponding to multiple locking rods 26. The outer ends of the two locking rods 26 in the same group are connected to adjusting plates 28. Two inspection plates 8 are rotatably provided with adjusting rods 29, and the adjusting plates 28 are provided with adjusting holes 30 corresponding to the adjusting rods 29. The adjusting rods 29 and the adjusting holes 30 are threadedly connected.

[0038] Specifically, when internal maintenance is required, rotating the adjusting rod 29 causes the adjusting rod 29 and the adjusting hole 30 to engage with each other, allowing the adjusting plate 28 and the locking rod 26 to be pulled outwards as a whole. After the locking rod 26 is pulled out from the locking hole 27, it hinges open the inspection plate 8 for internal maintenance. After the maintenance operation is completed, the inspection plate 8 is hinged closed, and rotating the adjusting rod 29 in the opposite direction causes the locking rod 26 to slide back to its original position and be inserted into the corresponding locking hole 27 to achieve closure and locking.

[0039] In summary, the overall equipment is in use:

[0040] When the inspection plate 8 is in the open / closed state, rotating the adjusting rod 29 causes the adjusting rod 29 and the adjusting hole 30 of the adjusting plate 28 to engage with each other, allowing the adjusting plate 28 and the locking rod 26 to be pulled out as a whole. The locking rod 26 is then pulled out from the locking hole 27, allowing the inspection plate 8 to be hinged open for easy internal maintenance and replacement. After maintenance is completed, the inspection plate 8 is hinged closed, and rotating the adjusting rod 29 in the opposite direction causes the locking rod 26 and the adjusting plate 28 to slide back to their original positions. The locking rod 26 is then inserted into the corresponding locking hole 27 to achieve closure and locking.

[0041] When the mounting shell 9 is being replaced, the mounting shell 9 with the stirring rod is severely worn after long-term use. The mounting shell 9 is disassembled, the bolts between the first connecting hole 17 and the second connecting hole 18 are removed, and the locking ring 15 and locking rod 13 are taken out as a whole. The two mounting shells 9 are taken out from the positions of the access plates 8 on both sides. After the new mounting shell 9 is inserted into the interior, it is installed in accordance with the rotating shaft 4. The mounting block 10 is inserted into the groove 11. The locking ring 15 and locking rod 13 are installed in accordance with the rotating shaft 4. The locking rod 13 is inserted into the through hole 12 and the locking hole 14 to achieve initial installation limit. The bolts are passed through the first connecting hole 17 and the second connecting hole 18 and tightened to achieve stable locking.

[0042] When the filter screen 20 is being replaced, after a long period of use, a large amount of impurities accumulate on the filter screen 20. The filter screen 20 is then disassembled and cleaned. The bolts between the first mounting hole 24 and the second mounting hole 25 are removed. The filter screen 20 and the mounting plate 22 are then disassembled and cleaned. After cleaning, the mounting plate 22 is installed in the mounting groove 23, and the bolts are passed through the first mounting hole 24 and the second mounting hole 25 and tightened to fix it.

[0043] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred.
