[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figures 1-4 This utility model provides a drying box for oil seal processing, including a box body 1. A negative pressure machine 2 is fixedly connected to one side of the top of the box body 1. A conveying pipe 3 connected to the negative pressure machine 2 is fixedly connected to one side of the box body 1 near the top. A connecting pipe 4 is fixedly connected to one side of the negative pressure machine 2. A drying tank 5 connected to the connecting pipe 4 is arranged in the middle of the top of the box body 1. A filter box 7 is fixedly connected to the other side of the top of the box body 1. A connecting pipe 6 connected to the filter box 7 is arranged on the outer contour of the drying tank 5 near the bottom. An exhaust pipe 8 connected to the filter box 7 is fixedly connected to the other side of the box body 1 near the top. An exhaust gas treatment mechanism is arranged inside the filter box 7.

[0024] By opening the door on chamber 1, the oil seals to be dried are placed into the working chamber on chamber 1 for drying. During the drying operation, the operator turns on the negative pressure machine 2. The negative pressure machine 2, conveying pipe 3, and connecting pipe 4 are used to transport the humid waste heat air generated during drying to the drying tank 5. The drying tank 5 dries the humid waste heat air. Then, the dried waste heat air is sent to the filter box 7 through the connecting pipe 6. The waste heat air is deodorized and sterilized by the waste gas treatment mechanism in the filter box 7. The dried and purified hot air is then sent back into chamber 1 through the exhaust pipe 8, so that the hot air can be reused to heat the oil seals, thereby improving the practicality of the equipment.

[0025] The exhaust gas treatment mechanism includes a deodorizing filter 71 snapped into one side of the inner cavity of the filter box 7, an activated carbon filter 72 snapped into the side of the inner cavity of the filter box 7 near the deodorizing filter 71, a photocatalytic filter 73 snapped into the side of the inner cavity of the filter box 7 near the activated carbon filter 72, a fixed lamp cover 74 fixedly connected to the other side of the inner cavity of the filter box 7, a UV sterilization lamp 75 installed at the bottom of the fixed lamp cover 74, a placement groove 19 opened at the top of the filter box 7, a sealing plate 20 snapped into the inner wall of the placement groove 19, threaded grooves 21 penetrating through the four corners of the inner wall of the placement groove 19 and the four corners of the top of the sealing plate 20, bolts 22 threadedly connected to the inner cavity of the threaded grooves 21, sliding grooves 23 fixedly connected to both sides of the deodorizing filter 71, the activated carbon filter 72 and the photocatalytic filter 73, and a sliding rod 24 adapted to them opened on the inner wall of the filter box 7.

[0026] After the dried waste heat air enters the filter box 7, the deodorizing filter 71, activated carbon filter 72, and photocatalytic filter 73 filter out toxic substances in the waste heat air. Then, the waste heat air is disinfected by the UV sterilization lamp 75 at the bottom of the fixed lamp cover 74. The purified hot air is then sent into the box 1. When the deodorizing filter 71, activated carbon filter 72, and photocatalytic filter 73 are damaged after long-term use, the operator can remove the bolt 22 in the threaded groove 21, then remove the sealing plate 20 from the placement groove 19, and then pull the damaged filter upward to move the sliding groove 23 upward from the sliding rod 24 opened in the inner wall of the filter box 7 for removal. Finally, the damaged filter can be replaced. This also makes it convenient for the operator to disassemble and replace the UV sterilization lamp 75 that is clipped to the bottom of the fixed lamp cover 74.

[0027] A snap-fit ​​plate 9 is fixedly connected to the middle of the box body 1 near the top. The top of the snap-fit ​​plate 9 has a snap-fit ​​groove 10 for the drying tank 5 to snap into. A snap-fit ​​component is provided on the outer contour of the snap-fit ​​plate 9. The snap-fit ​​component includes a sleeve 11 fixedly connected to the outer contour of the snap-fit ​​plate 9. A threaded plate 12 is threadedly connected to the inner wall of the sleeve 11 away from the snap-fit ​​plate 9. A hexagonal snap-fit ​​rod 13 is provided through the inner wall of the threaded plate 12. A connecting plate 14 is fixedly connected to the outer contour of the hexagonal snap-fit ​​rod 13. A return spring 16 is provided on the connecting plate 14 and sleeved with the hexagonal snap-fit ​​rod 13. An adjusting block 15 is fixedly connected to the end of the hexagonal snap-fit ​​rod 13 away from the snap-fit ​​plate 9. A snap-fit ​​groove 18 is provided through the outer contour of the snap-fit ​​plate 9 and the outer contour of the drying tank 5 near the bottom. An anti-slip sleeve 17 is sleeved on the outer contour of the adjusting block 15. An anti-slip groove is provided on the outer surface of the anti-slip sleeve 17.

[0028] After the drying tank 5 is damaged, the operator pulls the adjusting block 15 outward, causing the adjusting block 15 to move the hexagonal locking rod 13 outward from the slot 18 on the drying tank 5 and the locking plate 9. This causes the hexagonal locking rod 13 to push the connecting plate 14 against the return spring 16, thus preventing the hexagonal locking rod 13 from locking the drying tank 5. The drying tank 5 is then removed from the slot 10 on the locking plate 9, and a new drying tank 5 is replaced and locked into the slot 10. Next, the slot 18 on the drying tank 5 is aligned with the slot 18 on the locking plate 9. At this point, the adjusting block 15 is released, allowing the connecting plate 14 to... The return spring 16 is no longer compressed. The elasticity generated by the return spring 16 drives the hexagonal locking rod 13 to return to its original position, allowing the hexagonal locking rod 13 to enter the locking groove 18, thereby locking and limiting the drying tank 5. When the return spring 16 suffers metal fatigue damage, the operator pulls the adjusting block 15 outward to drive the hexagonal locking rod 13, so that the hexagonal locking rod 13 is fully inserted into the sleeve 11. Then, the adjusting block 15 is rotated to drive the hexagonal locking rod 13 to rotate. The rotating hexagonal locking rod 13 drives the threaded plate 12 to rotate, causing the threaded plate 12, which is threaded to the inner wall of the sleeve 11, to separate. Then, the return spring 16 can be replaced.

[0029] Working principle: By opening the door on the chamber 1, the oil seal to be dried is placed into the working chamber on the chamber 1 for drying. When the equipment is drying, the operator turns on the negative pressure machine 2. The negative pressure machine 2, the conveying pipe 3 and the connecting pipe 4 are used to transport the humid waste heat air generated during drying to the drying tank 5. The drying tank 5 dries the humid waste heat air. After the dried waste heat air enters the filter box 7, the deodorizing filter 71, the activated carbon filter 72 and the photocatalytic filter 73 are used to filter the toxic substances in the waste heat air. Then, the waste heat air is disinfected by the UV sterilization lamp 75 at the bottom of the fixed lamp cover 74. Finally, the purified hot air is sent into the chamber 1.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
