Description

Technical Field

[0001] This utility model relates to the field of circulation equipment, specifically a device for recycling stretching oil. Background Technology

[0002] In stamping and drawing manufacturing, stamping dies generate heat due to friction. To reduce friction, stamping dies are generally equipped with oil circuit boards to provide lubricating oil during the stamping process. The lubricating oil sprays out from the oil circuit board and flows down the worktable. The traditional method is to set up an oil basin at the bottom of the worktable for collection. Later, it is collected manually and then processed for reuse. However, during collection, it is not possible to quickly filter impurities in the oil.

[0003] According to the patent document CN216828289U, a stretching oil recycling device includes a collection device, an oil receiving pool, and an oil collection tank. The bottom of the oil receiving pool is inclined, and one side of it is open at the bottom, which is connected to the oil collection tank. A filter screen is installed on the opening to perform preliminary filtration of large particulate impurities. In use, after collection and filtration, the oil is lifted back to the worktable and then pumped into the stamping die, realizing the recycling of lubricating oil and reducing the production cost of enterprises. However, although the above-mentioned technical solution realizes recycling, it cannot actively apply pressure to speed up the filtration process during lubricating oil filtration, which is inconvenient in use. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a device for recycling stretching oil, thereby solving the problems mentioned in the background section. This invention features a novel structure. During use, lubricating oil is sprayed onto the inner wall of a rotating drum through a spray pipe. The rotating drum generates centrifugal force as it rotates, causing the lubricating oil to be thrown outwards for rapid filtration.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a stretching oil recycling device, comprising a housing, a drive motor and an oil inlet pipe fixedly mounted on the top of the housing, a cavity inside the housing, a rotating drum rotatably mounted inside the cavity, a fixed seat movably mounted on the top of the rotating drum, the fixed seat being fixedly mounted at one end of the oil inlet pipe, a rotating column mounted on the drive motor, a connecting hole on the fixed seat, and the rotating column being movably mounted inside the rotating drum through the connecting hole.

[0006] Furthermore, a slot is formed on the inner wall of the cavity, and an oil drain pipe is fixed to the side of the box body, with one end of the oil drain pipe connected to the slot.

[0007] Furthermore, the rotating barrel has an opening on its side, a filter plate is fixed on the inner wall of the opening, and a fixing column is fixed on the rotating column, with one end of the fixing column fixed to the inner wall of the rotating barrel.

[0008] Furthermore, a discharge port is provided at the bottom of the box, and a fixing block is fixed on the inner wall of the discharge port, and a lifting mechanism is fixedly installed on the fixing block.

[0009] Furthermore, a conical seat is fixed on the lifting mechanism, and the conical seat has a mounting hole. The conical seat is slidably mounted on the rotating column through the mounting hole.

[0010] Furthermore, a ring seat is rotatably mounted on the rotating column, a connecting column is welded onto the ring seat, a cleaning column is fixed to one end of the connecting column, and the cleaning column moves in contact with the inner wall of the rotating barrel.

[0011] Furthermore, a ring pipe is fixed to the bottom of the fixed base, and a spray pipe is fixed to the bottom of the ring pipe, with one end of the spray pipe engaging with the inner wall of the rotating barrel.

[0012] Furthermore, an air intake pipe is fixed to the side of the drive motor, and one end of the air intake pipe is connected to the cavity.

[0013] The beneficial effects of this utility model are:

[0014] 1. In use, the lubricating oil is sprayed onto the inner wall of the rotating drum through the spray pipe. The rotating drum generates centrifugal force as it rotates, and the lubricating oil is thrown outward for rapid filtration under the action of centrifugal force. The spray pipe makes the lubricating oil evenly enter the inner wall of the rotating drum and slide down, which facilitates rapid filtration in the later stage.

[0015] 2. In this utility model, after the conical seat moves downward, it enters the interior of the discharge port. The diameter of the discharge port is larger than the diameter of the conical seat. Impurities on the surface of the conical seat and the surface of the rotating barrel are discharged downward from the discharge port. After the conical seat moves upward, it squeezes the bottom of the cleaning column. After the cleaning column is squeezed, it scrapes against the inner wall of the filter plate. The scraping facilitates the removal of impurities. Attached Figure Description

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] Please see Figures 1 to 6 This utility model provides a technical solution: a stretching oil recycling device, including a housing 1. A drive motor 2 and an oil inlet pipe 3 are fixedly installed on the top of the housing 1. A cavity 6 is opened inside the housing 1. A rotating barrel 7 is rotatably installed inside the cavity 6. A fixed seat 9 is movably installed on the top of the rotating barrel 7. The fixed seat 9 is fixedly installed at one end of the oil inlet pipe 3. A rotating column 10 is installed on the drive motor 2. A connecting hole 22 is opened on the fixed seat 9. The rotating column 10 is movably installed inside the rotating barrel 7 through the connecting hole 22. A slot 11 is opened on the inner wall of the cavity 6. An oil drain pipe 5 is fixed on the side of the housing 1. One end of the oil drain pipe 5 is connected to the slot 11. The oil filtered by centrifugation enters the slot 11 and is discharged from the inside of the oil drain pipe 5.

[0025] In this embodiment, the rotating barrel 7 has an opening 8 on its side, and a filter plate is fixed on the inner wall of the opening 8. A fixing column 12 is fixed on the rotating column 10, and one end of the fixing column 12 is fixed on the inner wall of the rotating barrel 7. A discharge port 14 is opened at the bottom of the box 1, and a fixing block is fixed on the inner wall of the discharge port 14. A lifting mechanism 16 is fixedly installed on the fixing block, and a conical seat 15 is fixed on the lifting mechanism 16. The conical seat 15 has an installation hole 19, and the conical seat 15 is slidably installed on the rotating column 10 through the installation hole 19. The lifting mechanism 16 is a linear reciprocating electric push rod. The lifting mechanism 16 pushes the conical seat 15 to move up and down at the bottom of the rotating barrel 7. When the conical seat 15 moves upward inside the rotating barrel 7, it completes the squeezing and fixing of the cleaning column 13.

[0026] In this embodiment, a ring seat 17 is rotatably mounted on the rotating column 10, and a connecting column 18 is welded onto the ring seat 17. A cleaning column 13 is fixed to one end of the connecting column 18, and the cleaning column 13 moves in contact with the inner wall of the rotating barrel 7. A ring pipe 20 is fixed to the bottom of the fixed seat 9, and a spray pipe 21 is fixed to the bottom of the ring pipe 20. One end of the spray pipe 21 is engaged with the inner wall of the rotating barrel 7. An air inlet pipe 4 is fixed to the side of the drive motor 2, and one end of the air inlet pipe 4 is connected to the cavity 6. The spray pipes 21 are distributed at multiple points on the top of the rotating barrel 7, and the spray pipes 21 will evenly spray oil into the interior of the rotating barrel 7.

[0027] Working principle: External stretching oil enters the annular pipe 20 through the oil inlet pipe 3. Under pressure inside the annular pipe 20, the oil is sprayed out from the spray pipe 21. The oil sprayed from the spray pipe 21 enters the inner wall of the rotating drum 7, where a filter plate is fixed. The drive motor 2 is started to rotate the rotating column 10 and the rotating drum 7. The rotation of the rotating drum 7 causes the oil to be flung and filtered through the filter plate into the slot 11. The oil inside the slot 11 is discharged from the oil outlet pipe 5. While the rotating drum 7 rotates, the conical seat 15 moves to the bottom of the rotating drum 7. After centrifugal filtration in the rotating drum 7, the lifting mechanism 13 is activated to push the conical seat 15 upwards. The conical seat 15 is installed at one end of the lifting mechanism 13 via a bearing seat. As the conical seat 15 moves upward, one end of the cleaning column 13 contacts the side of the conical seat 15, and the conical seat 15 achieves frictional limiting of the cleaning column 13. Later, the drive motor 2 drives the rotating barrel 7 to rotate. When the rotating barrel 7 rotates, the cleaning column 13 remains stationary. The filter plate on the inner wall of the rotating barrel 7 rubs against the cleaning column 13 to scrape and clean the impurities on the surface. After scraping and cleaning, the conical seat 15 moves downward and enters the interior of the discharge port 14. The diameter of the discharge port 14 is larger than the diameter of the conical seat 15. The impurities on the surface of the conical seat 15 and the surface of the rotating barrel 7 are discharged downward from the discharge port 14.
