Description

Technical Field

[0001] The utility model relates to the technical field of rolling oil treatment, in particular to a rolling oil backwashing filter device. Background Art

[0002] Rolling oil, commonly referred to as lubricating or cooling oil, is used in rolling operations. During metalworking and rolling, rolling oil reduces friction between the metal and the rolls, thereby reducing energy consumption and extending roll life. It forms a thin lubricating film on the metal surface, making it easier for the metal to pass through the rolling mill.

[0003] The primary purpose of using a backwash filter for rolling oil is to ensure that the oil remains clean and efficient during use, thereby maintaining the stability and quality of the metalworking process. During the rolling process, debris, dust, or other solid particles may be generated on the metal surface. If these impurities are mixed into the rolling oil, they will affect the lubrication effect and processing quality. The backwash filter can effectively capture and remove these impurities, maintaining the cleanliness of the rolling oil.

[0004] However, most of the devices do not have a switching structure during use, which causes contamination of the pipeline during use, so that when the rolling oil is used for filtering next time, cross-contamination occurs, making filtering difficult. Utility Model Content

[0025] Specifically, the rolling oil enters the inner wall of the rolling oil filter tube 1 through the water-oil inlet pipe 23 and flows into the interior of the switching shell 2. When the rolling oil pushes the A-side sealing plate 3 to drive the connecting rod 4 and the B-side sealing plate 5 to move downward, the B-side sealing plate 5 blocks the drain outlet 8 to avoid the effect of cross contamination. The oil enters the interior of the filter tank body 13 and the filter mesh 20 through the oil inlet pipe 6 for filtering. During use, the switching shell 2 does not require power, which is convenient to use and avoids the effect of cross contamination.

[0026] See also Figure 1 and Figure 3The outer wall of the backwash water pipe 11 is fixedly connected to the filter tank body 13, the lower surface of the filter tank body 13 is fixedly connected to the motor 14, and the output end of the motor 14 is fixedly connected to the first gear 15; the outer wall of the first gear 15 is rotatably connected to the inner wall of the filter tank body 13, and the outer wall of the first gear 15 is meshedly connected to the second gear 16; the inner wall of the second gear 16 is fixedly connected to the drive rod 17, and the outer wall of the drive rod 17 is rotatably connected to the filter screen 20;

[0027] Specifically, water flows into the bottom of the filter tank body 13 through the backflushing water pipe 11. During the backflushing cleaning process, the motor 14 drives the first gear 15 and the second gear 16 to rotate, and the second gear 16 drives the driving rod 17 to further clean the filter screen 20. During use, it can better provide a better environment for the next filtration.

[0028] See also Figure 3 The outer wall of the driving rod 17 is fixedly connected to the cleaning support rod 18, and the outer wall of the cleaning support rod 18 is provided with a brush plate 19; the outer wall of the brush plate 19 is slidably connected to the inner wall of the filter screen 20, and the outer wall of the filter screen 20 is rotatably connected to the limit ring 22; the outer wall of the limit ring 22 is fixedly connected to the upper inner wall of the filter tank body 13, and the lower outer wall of the filter screen 20 is fixedly connected to the support block 21, and the outer wall of the support block 21 is fixedly connected to the lower inner wall of the filter tank body 13;

[0029] Specifically, when the cleaning support rod 18 and the brush plate 19 rotate on the inner wall of the filter screen 20, the foreign matter remaining on the inner wall of the filter screen 20 is cleaned by the brush plate 19, and the impurities remaining on the filter screen 20 can be further cleaned. The clean water sent in by the bottom backflushing water pipe 11 can discharge the cleaned impurities to the outside through the sewage outlet 8 to ensure the cleanliness of the interior.

[0030] Working principle: when the device needs to be used, the water valve 12 is closed by opening the oil valve 10, and the rolling oil enters the inner wall of the rolling oil filter tube 1 through the water-oil inlet pipe 23 and flows into the interior of the switching shell 2. During use, the rolling oil pushes the A-side sealing plate 3 to drive the connecting rod 4 and the B-side sealing plate 5 to move downward, and the drain outlet 8 is blocked by the B-side sealing plate 5 during use to avoid the effect of cross contamination. The oil enters the filter tank body 13 and the filter screen 20 through the oil inlet pipe 6 for filtering. After the filtration is completed, clean water is connected to the water-oil inlet pipe 23, and the water valve 12 is opened by closing the oil valve 10. At this time, the water flows into the bottom of the filter tank body 13 through the backwash water pipe 11. During the backwash cleaning process, the motor 14 drives the first gear 15 and the second gear 16 to rotate, and the second gear 16 drives the driving rod 17 to drive the cleaning support rod 18 and the brush plate 19 to rotate on the inner wall of the filter screen 20. The brush plate 19 cleans the foreign matter remaining on the inner wall of the filter screen 20. In order to further clean the impurities remaining on the filter screen 20, the clean water sent in through the backwash water pipe 11 during use cleans the impurities, and the sewage flows into the interior of the switching shell 2 through the sewage outlet 8 in the upper cover 7, and drives the connecting rod 4 and the A surface sealing plate 3 to send the sewage into the sewage pipe 9 by pushing the B surface sealing plate 5. During use, the switching shell 2 has a switching effect, and during use, the effect of cross-contamination of rolling oil caused by the same pipeline can be avoided. During use, the device not only drives the A surface sealing plate 3 to push the B surface sealing plate 5 to block the sewage outlet 8 by the rolling oil, sprays it into the interior of the switching shell 2 through the sewage outlet 8, pushes the B surface sealing plate 5 to block the A surface sealing plate 3 to block the switching shell 2 and the oil inlet pipe 6 from the sewage pipe 9 to the outside, avoiding cross contamination, but also has the effect of further cleaning the impurities intercepted in the filter screen 20 by driving the cleaning support rod 18 and the brush plate 19 through the driving rod 17, which can further increase the backwash cleanliness effect.
