Description

Technical Field

[0001] This utility model relates to the field of papermaking machine technology, and in particular to a papermaking machine recycle thin oil dehydration device. Background Technology

[0002] In the traditional method, lubricating thin oil or hydraulic oil is directly returned to the oil station for recycling after the work is completed. However, since papermaking machines require a large amount of water during the papermaking process, some water will inevitably enter the lubricating thin oil or hydraulic oil. Water seepage into the oil will cause emulsification, which will lead to lubrication failure or affect the performance. Therefore, a water removal device is used to remove the water from the recycled oil to ensure that the recycled oil can work normally.

[0003] The existing paper machine's recycled thin oil dehydration device lacks an auxiliary lifting structure for the water-absorbing filter cartridge. After the filter cartridge becomes saturated, it absorbs a large amount of water, resulting in a significant increase in weight. This requires considerable physical effort from the operator during the pulling process, making the operation very strenuous. The filter cartridge is also prone to jamming, further increasing the difficulty of replacement and reducing work efficiency.

[0004] Therefore, in view of the existing paper machine recycling thin oil dewatering device, which lacks an auxiliary lifting structure for the water-absorbing filter element during use, and whose filter element is heavy after saturation, making it difficult for workers to pull out the filter element and inconvenient to replace it quickly, there is an urgent need to design a new type of paper machine recycling thin oil dewatering device. Utility Model Content

[0005] To overcome the problem that existing paper machine recycle thin oil dewatering devices lack an auxiliary lifting structure for the water-absorbing filter cartridge during use, and that the water-absorbing filter cartridge is heavy after saturation, making it difficult for workers to pull out the water-absorbing filter cartridge and inconvenient for quick replacement.

[0006] The technical solution of this utility model is as follows: a papermaking machine recycled thin oil dewatering device, comprising a dewatering container body, a mounting frame, a drive motor, a lead screw, a movable seat, a sleeve, and a telescopic rod. A top cover is provided at the top center of the dewatering container body, and an oil inlet is connected to the top left side of the top cover. A mounting seat is provided at the top center of the top cover, and a positioning seat is provided inside the mounting seat. A water-absorbing filter element is engaged inside the positioning seat. A mounting frame is provided on the top right side of the top cover, and a drive motor is installed on the top of the mounting frame. The output end of the drive motor passes through the top of the mounting frame and is connected to one end of the lead screw. The other end of the lead screw is rotatably connected to the inner bottom end of the mounting frame. A movable seat is threaded through the outer surface of the lead screw. A sleeve is installed on the left side of the movable seat, and a telescopic rod is inserted into the left end of the sleeve.

[0007] Preferably, by setting a drive motor, its output end can drive the lead screw to rotate during operation. When the lead screw rotates, it can drive the moving seat that is threaded with it to move up and down. When the operator lifts the water-absorbing filter element, he first lowers the moving seat to the bottom, then pulls out the telescopic rod so that the telescopic rod passes through the handle of the water-absorbing filter element. Then, the drive motor is started to control the lead screw to rotate and drive the moving seat to move up, so that the telescopic rod can assist in lifting. This allows the operator to pull out the water-absorbing filter element for replacement more easily. This solves the problem that the existing paper machine recycling thin oil dewatering device lacks an auxiliary lifting structure for the water-absorbing filter element. The water-absorbing filter element is heavy when saturated, which makes it difficult for the operator to pull out the water-absorbing filter element and is not convenient for quick replacement.

[0008] Preferably, the bottom of the top cover is fitted with the A chamber container body, and the bottom of the mounting base is fitted with the C chamber container body. Both the A chamber container body and the C chamber container body have several holes around their perimeter.

[0009] Preferably, an inclined plate is provided at the lower part of the interior of the water removal container body, and a drain interface is installed at the lower left part of the outer surface of the water removal container body.

[0010] Preferably, an oil outlet is installed on the upper right side of the outer surface of the water removal container body, and a connecting flange is installed on the end of both the oil inlet and the oil outlet away from the water removal container body.

[0011] Preferably, the left side of the main body of the water removal container is connected to two symmetrically arranged connecting pipes, and a transparent pipe connects the two connecting pipes.

[0012] Preferably, a circular groove is provided on the inner side of the positioning seat, and placement grooves are provided on both the left and right ends of the top of the positioning seat, with the bottom of the placement grooves communicating with the top of the circular grooves.

[0013] Preferably, sliders are installed on both the front and rear sides of the telescopic rod, and the telescopic rod is slidably connected to the sleeve through the sliders.

[0014] The beneficial effects of this utility model are:

[0015] 1. By setting up a drive motor, the moving seat drives the telescopic rod to move up and down with the help of the lead screw transmission structure. The telescopic rod can extend and retract through the handle of the water-absorbing filter element, so that it can assist in lifting the water-absorbing filter element when it rises. This allows the staff to pull out the water-absorbing filter element for replacement more easily and efficiently. After the water-absorbing filter element is saturated, the traction force provided by the telescopic rod can pull out the water-absorbing filter element. This not only reduces labor intensity but also improves maintenance efficiency and ensures that the replacement process is more convenient and safe. Attached Figure Description

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please see Figures 1-6This utility model provides an embodiment: a paper machine recycled thin oil dewatering device, including a dewatering container body 1, a mounting frame 7, a drive motor 8, a lead screw 9, a movable seat 10, a sleeve 11, and a telescopic rod 12. A top cover 2 is located at the top center of the dewatering container body 1. An oil inlet 3 is connected to the top left side of the top cover 2. A mounting seat 4 is located at the top center of the top cover 2. A positioning seat 5 is located inside the mounting seat 4, and a water-absorbing filter element 6 is engaged inside the positioning seat 5. The mounting frame 7 is located at the top right side of the top cover 2. The drive motor 8 is mounted on the top of the mounting frame 7. The output end of the drive motor 8 passes through the top of the mounting frame 7 and is connected to one end of the lead screw 9. The other end of the lead screw 9 is rotatably connected to the inner bottom end of the mounting frame 7. The outer surface of the lead screw 9 is threadedly connected to the movable seat 10. A sleeve 11 is installed on the left side, and a telescopic rod 12 is inserted into the left end of the sleeve 11. The screw 9 is driven to rotate by the drive motor 8. The screw 9 and the moving seat 10 form a threaded transmission, thereby converting the rotational motion into the linear lifting motion of the moving seat 10. When the operator needs to replace the water-absorbing filter element 6, he first lowers the moving seat 10 to the lowest working position, and then manually pulls the telescopic rod 12 to pass through the handle structure of the water-absorbing filter element 6. After starting the drive motor 8, the screw 9 rotates under the drive of the drive motor 8, which drives the moving seat 10 that is engaged with it to rise vertically. During this process, the telescopic rod 12 fixed on the moving seat 10 is raised synchronously. The handle applies a vertical upward traction force to the water-absorbing filter element 6, thereby significantly reducing the operation intensity required for manually lifting the water-absorbing filter element 6 and realizing the safe and efficient replacement of the water-absorbing filter element 6.

[0025] Please see Figures 1-4 In this embodiment, the bottom of the top cover 2 is equipped with the A chamber container body 14, and the bottom of the mounting base 4 is equipped with the C chamber container body 15. The A chamber container body 14 and the C chamber container body 15 are provided with several holes. By setting the A chamber container body 14 and the C chamber container body 15, the A chamber container body 14 and the water removal container body 1 are combined to form the B chamber. The three chambers are lubricated with oil for water removal and filtration. The lower part of the interior of the water removal container body 1 is provided with an inclined plate 16. The lower left side of the outer surface of the water removal container body 1 is provided with a drain port 17. By setting the inclined plate 16, after the lubricating oil in the B chamber settles and stratifies, the water is in the lower layer and can be discharged through the drain port 17. The upper right side of the outer surface of the water removal container body 1 is provided with an oil outlet 18. The oil inlet 3 and the oil outlet 18 are both provided with a connecting flange 19 at the end away from the water removal container body 1. By setting the oil outlet 18, the lubricating oil at the top of the B chamber can be pumped back into the hydraulic station for circulation by the circulation pump.

[0026] Please see Figures 1-6In this embodiment, two symmetrically connected pipes 20 are connected to the left side of the main body of the water removal container 1. A transparent pipe 21 connects the two connected pipes 20. By setting the connected pipes 20 and the transparent pipe 21, the pressure inside the transparent pipe 21 is the same as that inside the main body of the water removal container 1. The lubricating oil level inside the transparent pipe 21 is the same as the lubricating oil level inside the main body of the water removal container 1, which makes it easy for the staff to observe the liquid level. A circular groove 22 is opened on the inner side of the positioning seat 5, and placement grooves 23 are opened on both the left and right ends of the top of the positioning seat 5. The bottom of the placement groove 23 is connected to the top of the circular groove 22. By setting the placement groove 23 and the circular groove 22, when installing the water-absorbing filter element 6, the locking blocks at both ends of the top of the water-absorbing filter element 6 can be aligned with the placement groove 23 and inserted, and then rotated 90 degrees to achieve the positioning of the water-absorbing filter element 6. The front and rear sides of the telescopic rod 12 are equipped with sliders 13. The telescopic rod 12 is slidably connected to the sleeve 11 through the sliders 13. By setting the sliders 13, the movement direction of the telescopic rod 12 can be restricted, and the stability of the movement of the telescopic rod 12 can be improved.

[0027] During operation, the recycled circulating oil enters chamber A through inlet 3. After automatic separation of oil and water, the oil forms an upper layer and water a lower layer based on their physical properties. Both chamber A (container body 14) and chamber C (container body 15) are equipped with filters. The separated water passes through small holes in the wall of chamber C (container body 15) and then through the filter in chamber A into chamber C, where it is completely absorbed by the water-absorbing filter element 6. The completely water-absorbed circulating oil then passes through chamber A from chamber C into chamber B, and from chamber B through outlet 18 into the oil station. During the working cycle, the water that is not absorbed by the bottom water-absorbing filter element 6 is discharged into the corresponding water recovery device through the drain interface 17. The water-absorbing filter element 6 is composed of ion exchange resin, ion water-absorbing factor, water-locking particles, metal particles, stainless steel filter screen and skeleton. It can effectively remove water from the oil outlet and filter out suspended particles such as mud, rust, iron filings, and colloids. As the amount of water removed by filtration increases, the water-absorbing filter element 6 gradually becomes ineffective and needs to be replaced regularly. It can be assisted by lifting with the screw 9 transmission structure and the telescopic rod 12, making replacement more labor-saving and convenient.

[0028] Through the above steps, by using a drive motor 8 to drive a lead screw 9, the rotation of the lead screw 9 drives the threaded moving seat 10 to move up and down, thereby achieving mechanically assisted replacement of the water-absorbing filter element 6. During operation, the operator first controls the drive motor 8 to reverse so that the moving seat 10 is lowered to the lowest position. Then, the operator manually pulls the telescopic rod 12 to pass through the filter element handle. After starting the drive motor 8 to rotate forward, the lead screw 9 drives the moving seat 10 to rise smoothly, driving the telescopic rod 12 to lift the filter element vertically. This significantly reduces the manual lifting effort. Utilizing the smoothness and precise positioning advantages of the lead screw 9 transmission, combined with the operational flexibility of the telescopic rod 12, it is particularly suitable for the safe and efficient replacement of the water-absorbing filter element 6. This solves the problem that existing paper machine recycling thin oil dewatering devices lack an auxiliary lifting structure for the water-absorbing filter element 6 during use. The water-absorbing filter element 6 is quite heavy after saturation, making it difficult for operators to pull it out and hindering quick replacement.
