Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel strip production technology, and in particular to a cleaning oil filtration device for cleaning steel strips. Background Technology
[0002] Steel strip is the raw material for manufacturing steel measuring tapes. Before being made into measuring tapes, the steel strip needs to be cut and ground. During cutting and grinding, cutting oil is often used to improve the cutting and grinding process, leaving the steel strip with oil stains after cutting. This can easily affect subsequent operations such as coloring the steel strip. To address this, cleaning devices have been designed. These devices immerse the steel strip in volatile cleaning oils such as kerosene or diesel oil. The cleaning oil softens and dilutes the oil stains, ensuring the steel strip's cleanliness. During cleaning, residual metal shavings and dust particles on the steel strip are released into the cleaning oil, further cleaning the strip. There is a risk of scratching the steel belt during the cleaning process. Therefore, some steel belt cleaning devices use a circulating pump to send the cleaning oil into the filter device and then back to the cleaning tank. After a period of use, solid particles accumulate on the filter cloth of the existing filter device, which requires regular replacement. The filter cloth of the existing device is mostly fixed inside the filter device, which is not easy to replace. Moreover, the machine needs to be stopped when replacing the filter cloth, which increases the difficulty of operation. Therefore, there is a need for a cleaning oil filtration device for steel belt cleaning. Its filter cloth is wound and set at the lower part of the oil drain pipe, so that workers can easily replace the filter cloth without stopping the machine, thus improving work efficiency. Utility Model Content
[0003] To address the aforementioned problems, this utility model proposes a cleaning oil filtration device for steel belt cleaning, wherein the filter cloth is wound and installed at the lower part of the oil drain pipe, allowing workers to easily replace the filter cloth without stopping the machine, thereby improving work efficiency.
[0004] This utility model is achieved through the following technical solution:
[0005] This utility model proposes a cleaning oil filtration device for cleaning steel belts, comprising: a cleaning tank, a filter tank, an oil storage tank, and a filter cloth roll. The cleaning tank is connected to the ground via a first support frame. The filter tank is located below the cleaning tank and is connected to the cleaning tank via an oil drain pipe. The oil storage tank is located below the filter tank and is connected to the filter tank. The oil storage tank is connected to the cleaning tank via an oil pump and a return oil pipe. A second support frame is provided on one side of the filter tank, and the filter cloth roll is installed on the second support frame. One end of the filter cloth on the filter cloth roll passes under the oil drain pipe and overlaps the other side of the filter tank, with the filter cloth fitting against the bottom surface of the filter tank.
[0006] Furthermore, the lower part of the filter tank is provided with a grid, and the lower part of the filter cloth is supported at the bottom of the filter tank by the grid.
[0007] Furthermore, the grille is arranged in a V-shape at an angle in the filter tank.
[0008] Furthermore, the upper part of the oil drain pipe extends upward from the bottom of the cleaning tank by 10cm to 15cm, the upper part of the oil drain pipe is open, and the upper part of the oil drain pipe is provided with an oil drain port.
[0009] Furthermore, the second support frame is provided with a support rod that passes through the middle of the filter cloth roll, and a limiting block is provided on the support rod.
[0010] Furthermore, the upper part of the return oil pipe is higher than the cleaning tank, and the upper part of the return oil pipe is connected to the cleaning tank through a universal joint.
[0011] The beneficial effects of this utility model are as follows: By setting a filter cloth roll at the bottom of the oil drain pipe, the filter cloth is pulled out and placed between the oil drain pipe and the grid, thereby using the filter cloth to filter out solid particles in the cleaning oil and prevent solid particles from suspending in the cleaning oil and scratching the steel belt. When replacing, you only need to pull out the new filter cloth from the filter cloth roll and cut off the old filter cloth. The whole replacement operation is fast and does not require stopping the machine, thus improving work efficiency. Attached Figure Description

[0021] like Figures 1 to 5 As shown, an embodiment of this utility model provides a cleaning oil filtration device for cleaning steel belts, including: a cleaning tank 1, a filter tank 2, an oil storage tank 3, and a filter cloth roll 7. The cleaning tank 1 is connected to the ground through a first support frame 8. The filter tank 2 is located below the cleaning tank 1 and is connected to the filter tank 2 through an oil drain pipe 4. The oil storage tank 3 is located below the filter tank 2 and is connected to the filter tank 2. The oil storage tank 3 is connected to the cleaning tank 1 through an oil pump 5 and an oil return pipe 6. A second support frame 9 is provided on one side of the filter tank 2. The filter cloth roll 7 is installed on the second support frame 9. One end of the filter cloth 11 on the filter cloth roll 7 passes under the oil drain pipe 4 and overlaps the other side of the filter tank 2, and the filter cloth 11 is cut into the bottom surface of the filter tank 2.
[0022] After the steel belt is cleaned in the cleaning tank 1, the oil and solid particles such as dust and metal shavings carried on the steel belt will enter the cleaning oil. The cleaning oil in the cleaning tank 1 flows into the drain pipe 4 through the drain port on the wall of the drain pipe 4 or the opening at the top of the drain pipe 4, and flows into the filter tank 2 under the action of gravity. At this time, the filter cloth 11 is located below the drain pipe 4, so the solid particles in the cleaning oil are filtered through the filter cloth 11. The filtered cleaning oil flows into the oil storage tank 3 after passing through the grid 10. The oil in the oil storage tank 3 is sent back to the cleaning tank 1 through the oil pump 5 and the return oil pipe 6, realizing the circulation of the cleaning oil and the filtration during the circulation process. After a period of filtration, the solids in the cleaning oil will accumulate on the filter cloth 11. When the filter cloth 11 needs to be replaced, pull one end of the filter cloth 11 to pull the old filter cloth 11 out of the filter tank 2. The new filter cloth is pulled out from the filter cloth roll 7 and laid at the bottom of the filter tank 2 to complete the replacement. The replacement process is simple, easy to operate, and does not require machine shutdown, ensuring continuous production.
[0023] In a specific embodiment, such as Figure 3 As shown, a grid 10 is provided at the lower part of the filter tank 2. The lower part of the filter cloth 11 is supported at the bottom of the filter tank 2 by the grid 10. The grid 10 supports the lower part of the filter cloth 11 to prevent the filter cloth 11 from being damaged or washed into the oil storage tank 3 by the washing oil. The width of the filter cloth 11 is larger than the width of the grid 10, so as to ensure that the washing oil flows into the oil storage tank 3 only after passing through the filter cloth 11, thus ensuring effective filtration.
[0024] Preferably, such as Figure 5 As shown, the grid 10 is set in a V-shape and inclined in the filter tank 2. The filter cloth 11 is soft and can fit the shape of the grid 10 and adhere to the grid 10. This allows the cleaning oil to flow in spontaneously under the action of gravity and collect in the middle of the filter tank 2, preventing the cleaning oil from washing solid particles to the sides of the filter tank 2. After the cleaning oil flows from the oil drain pipe 4 to the upper part of the filter cloth 11, it will penetrate downward from the filter cloth 11 under the action of gravity. In addition, the grid 10 is set in a V-shape and inclined, which can effectively prevent the cleaning oil from flowing horizontally on the filter cloth 11 and prevent the cleaning oil from flowing directly from the grid 10 into the oil storage tank 3.
[0025] Preferably, such as Figure 2 As shown, the upper part of the oil drain pipe 4 extends upward from the bottom of the cleaning tank 1 by 10cm to 15cm. The upper part of the oil drain pipe 4 is open, and the upper part of the pipe wall of the oil drain pipe 4 is provided with an oil drain port. Part of the cleaning oil in the cleaning tank 1 flows into the oil drain pipe 4 from the oil drain port, and the other part overflows into the oil drain pipe 4 through the upper opening of the oil drain pipe 4 because the oil level in the cleaning tank 1 is too high. Thus, the height of the cleaning oil in the cleaning tank 1 is controlled by the oil drain pipe 4, and the cleaning oil is circulated.
[0026] In a preferred embodiment, such as Figure 4 , Figure 5 As shown, the second support frame 9 is provided with a support rod 12, which passes through the middle of the filter cloth roll 7, and a limiting block 13 is provided on the support rod 12. The filter cloth roll 7 can rotate on the support rod 12, which makes it easy to pull out a new filter cloth 11 from the filter cloth roll 7 and facilitate the replacement of the filter cloth 11.
[0027] In a preferred embodiment, the upper part of the return oil pipe 6 is higher than that of the cleaning tank 1, and the upper part of the return oil pipe 6 is connected to the cleaning tank 1 through a universal joint. The universal joint is a commercially available universal joint, which can control the cleaning oil to flow back to the cleaning tank 1 and then spray onto the steel belt, so that the steel belt can fully contact the cleaning oil.
[0028] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
