After the lubricating oil has been used for a certain period of time, in order to ensure the operation of the machinery, it is necessary to change the oil regularly, which generates a large amount of waste lubricating oil. In order to reduce the waste of lubricating oil, distillation technology is usually used to regenerate the waste oil to reduce the consumption of lubricating oil resources.

By opening the valve, the lubricating oil can enter the observation box and the inspection box, so that the distillation device can perform sample detection. The detection component 5 is a prior art and will not be described in detail in this article.

[0034] Reference Figure 1 The discharge assembly 6 is specifically fixedly connected to the front side of the collecting box 4, and the container 7 is specifically fixedly connected to the end of the discharge assembly 6 away from the collecting box 4. The discharge assembly 6 is composed of an oil pump and an oil outlet pipe. By driving the oil pump, the oil outlet pipe can deliver the lubricating oil into the interior of the container 7. At the same time, the container 7 can be removed, and the discharge assembly 6 is a prior art and will not be described in detail in this article. Two filter plates 23 are slidably connected to the middle of the collecting box 4.

[0035] Reference Figure 1-3 A U-shaped block 8 is fixedly connected to the front side of the distillation tank 1, and two pulleys 9 are rotatably connected inside the U-shaped block 8. A belt 10 is provided on the outer periphery of the two pulleys 9, and a threaded rod 11 is fixedly connected to the top of the belt 10. A nut sleeve 12 is threadedly connected to the outer periphery of the threaded rod 11, and a storage box 13 is fixedly connected between the two nut sleeves 12. A hose 14 is fixedly connected to the side of the storage box 13 close to the distillation tank 1, and a connecting pipe 15 is fixedly connected to the other end of the hose 14. When one of the pulleys 9 rotates, the two pulleys 9 can drive the two threaded rods 11 to rotate at the same time under the action of the belt 10. When the threaded rod 11 rotates, the nut sleeve 12 can drive the storage box 13 to move upward, and at the same time, the lubricating oil can flow out of the storage box 13 under the action of the hose 14 and the connecting pipe 15.

[0036] Reference Figure 1-3A compression spring 17 is fixedly connected to the inside of the U-shaped block 8, and the other end of the compression spring 17 is fixedly connected to the rack plate 16. A circular gear 18 is rotatably connected to the middle of the storage box 13, and a half gear 19 is rotatably connected to the inside of the storage box 13. The two sides of the circular gear 18 are respectively meshed with the rack plate 16 and the half gear 19. A groove 29 is opened in the middle of the U-shaped block 8, and the side of the circular gear 18 away from the half gear 19 is slidably connected to the middle of the groove 29.

[0037] Reference Figure 1-3 When the storage box 13 moves upward, the circular gear 18 will contact the rack plate 16, and the circular gear 18 can be rotated. When the circular gear 18 rotates, the half gear 19 can drive the baffle 21 to move downward, thereby releasing the restriction on the connecting pipe 15 and turning the connecting pipe 15 toward the distillation tank 1, so that the lubricating oil inside the storage box 13 can flow into the distillation tank 1. At the same time, when the pulley 9 rotates in the opposite direction, the threaded rod 11 and the nut sleeve 12 can drive the storage box 13 to move downward. During the movement, the rack plate 16 can rotate the circular gear 18 in the opposite direction. When the circular gear 18 rotates, the half gear 19 can drive the baffle 21 to move upward. When the baffle 21 moves, it will contact the hose 14 and the connecting pipe 15, so that the connecting pipe 15 can be collected in the middle of the storage box 13 and restricted, thereby preventing the lubricating oil from flowing out.

[0038] Reference Figure 2 A driving assembly is fixedly connected to the inside of the U-shaped block 8, and the driving assembly includes a motor 22. The motor 22 is fixedly connected to the inside of the U-shaped block 8, and the bottom of one of the pulleys 9 is fixedly connected to the output end of the motor 22. The driving motor 22 can drive the pulley 9 to rotate forward or reverse. There is no need for employees to manually pour the waste lubricating oil into the distillation tank 1, thereby reducing the danger of the waste lubricating oil distillation work and reducing the labor intensity of employees.

[0039] Reference Figure 1 , Figure 4 and Figure 5 The front and rear sides of the filter plate 23 are fixedly connected with positioning blocks 30, which are plugged into the collection box 4. The middle of the collection box 4 is provided with two positioning grooves 31 on both sides. The positioning blocks 30 are specifically plugged into the positioning grooves 31. Under the action of the positioning grooves 31, the filter plate 23 can quickly enter the middle of the collection box 4, and the installation plate 24 can quickly align with the collection box 4 and enter the interior of the collection box 4, thereby improving the installation speed of the filter plate 23.

[0040] Reference Figure 4-6A mounting plate 24 is fixedly connected to the right side of the two filter plates 23, and a spring 25 is fixedly connected inside the mounting plate 24. A block 26 is fixedly connected to the other end of the spring 25. A slot 27 is provided in the middle of the collecting box 4, and the block 26 and the slot 27 are plugged together. When the mounting plate 24 enters the collecting box 4, the collecting box 4 will contact the block 26 and squeeze the block 26 to move the block 26. When the block 26 moves, the spring 25 will be compressed, so that the filter plate 23 can completely enter the middle of the collecting box 4. At this time, the block 26 and the slot 27 are in parallel positions and the block 26 is not squeezed by external force. Under the action of the spring 25, the block 26 can be bounced into the slot 27, so that the mounting plate 24 and the filter plate 23 can be quickly fixed. A disassembly component is slidably connected to the middle of the mounting plate 24.

[0041] Reference Figure 4-6 The disassembly assembly includes a pull rod 28, which is slidably connected to the middle part of the mounting plate 24. A slide groove 20 is provided in the middle part of the mounting plate 24. The pull rod 28 is specifically slidably connected to the middle part of the slide groove 20. The slide groove 20 can limit the pull rod 28 to prevent the pull rod 28 from tilting, so that the pull rod 28 can only move in parallel. The side of the pull rod 28 close to the mounting plate 24 is fixedly connected to the side of the block 26 close to the spring 25. The block 26 can be pulled out of the slot 27 by pulling the pull rod 28, and then the mounting plate 24 can be disassembled. At the same time, the filter plate 23 can be quickly disassembled, which can increase the disassembly speed of the filter plate 23. A sealing gasket 32 ​​is fixedly connected to the outer side of the mounting plate 24, and a sealing groove 33 is provided on the right side of the collection box 4. The sealing gasket 32 ​​and the sealing groove 33 are plugged in and matched. Under the action of the sealing gasket 32 ​​and the sealing groove 33, the sealing between the mounting plate 24 and the collection box 4 can be improved, and air and oil leakage can be prevented.

[0042] Working principle: When in use, the two pulleys 9 can drive the two threaded rods 11 to rotate by driving the motor 22 and under the action of the belt 10, so that the storage box 13 can move upward. At the same time, when the storage box 13 moves, the circular gear 18 will mesh with the rack plate 16, so that the circular gear 18 can rotate. When the circular gear 18 rotates, the half gear 19 can drive the baffle 21 to rotate downward, so as to release the restriction on the connecting pipe 15. At this time, the connecting pipe 15 falls on the top of the distillation tank 1, so that the waste lubricating oil inside the storage box 13 can enter the distillation tank 1, and the storage box 13 can be moved downward by driving the motor 22 to drive the two threaded rods 11 to rotate in the opposite direction. When the storage box 13 moves downward and under the action of the rack plate 16, the circular gear 18 can rotate in the opposite direction, so that the half gear 19 can drive the baffle 21 to move upward, so as to squeeze the connecting pipe 15, so that the hose 14 can be bent and the connecting pipe 15 can be retracted to the middle of the storage box 13.

[0043] Among them, when the filter plate 23 needs to be cleaned, the block 26 and the slot 27 can be separated by pulling the pull rod 28, and the restriction on the mounting plate 24 can be released. At this time, the filter plate 23 can be taken out by pulling the mounting plate 24, and the positioning block 30 is inserted into the middle of the collection box 4. When entering, the collection box 4 will contact and squeeze the block 26. When the block 26 is squeezed, the spring 25 will be compressed, and the filter plate 23 can be completely entered into the collection box 4. When the slot 27 moves to the original position of the block 26, the block 26 can be bounced into the slot 27 under the action of the spring 25, and the filter plate 23 can be fixed.
