[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Reference Figure 3 - Figure 5The utility model provides an embodiment of an adjustable lubricating oil impurity removal device, comprising a separation barrel 1, a limiting ring 2 is fixedly connected to the lower end of the inner wall of the separation barrel 1, a filter plate 3 is installed on the upper side of the limiting ring 2, and a card slot 19 is fixedly connected to the left and right ends of the inner side of the limiting ring 2. A card block 20 is fixedly connected to the inside of the card slot 19 by bolts, and the top of the card block 20 is fixedly connected to the lower side of the filter plate 3. A scraper 4 is provided on the upper side of the filter plate 3, and a cover plate 5 is fixedly connected to the top of the separation barrel 1. A first electric push rod 6 is fixedly connected to the middle part of the cover plate 5. A piston plate 7 is fixedly connected to the driving end of the first electric push rod 6. The outer side of the piston plate 7 is connected to the separation barrel 1. The inner wall of the barrel 1 fits tightly, and the upper middle side of the filter plate 3 is rotatably connected to a rotating rod 13. The outer wall of the lower end of the rotating rod 13 is fixedly connected to the middle of the scraper 4. A spiral groove 14 is provided at the upper end of the rotating rod 13, and a receiving groove 11 is provided inside the driving end of the first electric push rod 6 and in the middle of the piston plate 7. The receiving groove 11 is sleeved on the upper end of the rotating rod 13, and a movable rod 12 is fixedly connected to the inside of the receiving groove 11 in the middle of the piston plate 7. The outer wall of the movable rod 12 is movably connected to the inside of the spiral groove 14. The left side of the separation barrel 1 is fixedly connected to the feed pipe 8, the middle part of the feed pipe 8 is fixedly connected to the one-way valve 9, and the middle part of the bottom end of the separation barrel 1 is fixedly connected to the discharge port 10.

[0027] The piston plate 7 is arranged in close contact with the inner wall of the separation barrel 1. When the first electric push rod 6 drives the piston plate 7 to move downward, the internal space of the separation barrel 1 is compressed. After the lubricating oil enters the separation barrel 1, it completely covers the filter plate 3. The piston plate 7 descends and compresses the internal space, increasing the pressure, thereby promoting the lubricating oil to pass through the filter plate 3, and improving the efficiency of separating the lubricating oil from impurities. The one-way valve 9 is arranged so that the lubricating oil can only enter the separation barrel 1 through the feed pipe 8, and the lubricating oil and air inside the separation barrel 1 cannot be discharged through the feed pipe 8. Therefore, when the first electric push rod 6 drives the piston plate 7 to rise, a negative pressure is generated inside the separation barrel 1, thereby drawing the lubricating oil into the separation barrel 1 through the feed pipe 8 to separate impurities, so that the device can work continuously, thereby improving the efficiency of the device. The speed at which the piston plate 7 is driven down by the first electric push rod 6 can be controlled The size of the internal pressure, and thus the amount of impurities in the lubricating oil and the type of impurities can be used to adjust the filtering efficiency by the size of the pressure. When the piston plate 7 is lowered, the movable rod 12 is driven to lower. The movable rod 12 can only move vertically up and down, thereby cooperating with the spiral groove 14, and can drive the rotating rod 13 to rotate. The rotating rotating rod 13 can drive the scraper 4 to rotate. The rotating scraper 4 cleans the impurities on the upper side of the filter plate 3 and gathers them on the left and right sides of the scraper 4, thereby preventing impurities from covering the surface of the filter plate 3, causing the lubricating oil to be difficult to pass through the filter plate 3, affecting the separation efficiency. The cover plate 5, the first electric push rod 6 and the piston plate 7 are removed to expose the filter plate 3 inside the separation barrel 1. The hexagonal bolts of the fixed block 20 and the slot 19 are removed by tools, and the filter plate 3 can be replaced and cleaned.

[0028] Reference Figure 1 - Figure 3 The right side of the separation barrel 1 is fixedly connected to an exhaust pipe 15, and the end of the exhaust pipe 15 is threadedly connected to a cap 16. The right side of the separation barrel 1 is fixedly connected to the front of the exhaust pipe 15 corresponding to the right side of the separation barrel 1, and the middle part of the pressure relief pipe 17 is fixedly connected to a pressure valve 18. The bottom outer side of the separation barrel 1 is fixedly connected to a base 23, and a guide plate 24 is provided on the inner side of the base 23. The front and rear sides of the guide plate 24 are fixedly connected to a fixing plate 25, and the ends of the fixing plate 25 are respectively fixedly connected to the front and rear sides of the inner wall of the base 23. The front and rear ends of the upper side of the base 23 are fixedly connected to a second electric push rod 21, and the top of the second electric push rod 21 is fixedly connected to a fixing ear 22, and the ends of the fixing ear 22 are respectively fixedly connected to the outer side of the cover plate 5.

[0029] Starting the second electric push rod 21 can drive the fixed ear 22 to rise, thereby driving the cover plate 5 to rise. The rising cover plate 5 can take the first electric push rod 6 and the piston plate 7 away from the interior of the separation barrel 1, exposing the internal structure of the separation barrel 1, which is convenient for cleaning and replacement of the filter plate 3. The set pressure valve 18 is mainly switched by the size of the pressure. When the piston plate 7 drops, causing the internal pressure of the separation barrel 1 to be too high and exceed the safety value, the pressure valve 18 opens to reduce the internal pressure of the device to avoid danger. When the pressure drops below the safety value, the pressure valve 18 closes.

[0030] Working principle: inject the lubricating oil to be processed into the separation barrel 1 through the provided feed pipe 8, then tighten the cap 16, start the provided first electric push rod 6 to drive the piston plate 7 to descend, the descending piston plate 7 compresses the internal space of the separation barrel 1, increases the pressure, thereby promoting the lubricating oil to pass through the filter plate 3 and promote separation, the descending piston plate 7 drives the movable rod 12 to descend, the descending movable rod 12 cooperates with the spiral groove 14, and can drive the rotating rod 13 to rotate, and the rotating rotating rod 13 can drive the scraper 4 to rotate, thereby cleaning the impurities on the upper side of the filter plate 3, and the lubricating oil passing through the filter plate 3 The oil is discharged from the discharge port 10, and the first electric push rod 6 drives the piston plate 7 to rise. The rising piston plate 7 generates negative pressure in the separation barrel 1, thereby drawing the lubricating oil into the separation barrel 1 through the feed pipe 8 for separation processing. The pressure valve 18 is opened when the pressure in the separation barrel 1 is too high to reduce the pressure in the separation barrel 1 and avoid damage to the internal structure. The cap 16 is opened, and the second electric push rod 21 can drive the first electric push rod 6 and the piston plate 7 to rise through the fixing ear 22 and the cover plate 5, and be exposed from the separation barrel 1, so as to facilitate cleaning of the device and replace the filter plate 3.
