Description

Technical Field

[0001] The invention belongs to the technical field of filters, and in particular relates to a device and method for quickly replacing an oil filter element. Background Art

[0002] The thin oil lubrication system of the bar line of the steel plant uses a filter to filter the lubricating oil. The filter is equipped with a partition, a filter element is plugged on the partition, a pressure plate is installed above the filter element, and a cover is fixed above the filter. After a period of operation, the filter element is blocked and needs to be replaced. The current method of replacing the filter element is to first release the lubricating oil in the filter into a temporary barrel, then remove the cover body and the pressure plate, pull out the filter elements one by one, and install the new filter element and then reinstall it. In this process, the lubricating oil is very easy to spill on the ground, making the ground slippery. The ground needs to be cleaned, otherwise the staff will slip. To release the oil into the temporary barrel, the temporary barrel needs to be cleaned in advance, otherwise it will cause contamination to the oil. The whole process requires multiple laborers, and there are many filters, which is labor-intensive. Summary of the invention

[0033] A plurality of universal wheels 17 are installed at the bottom of the base 1 to drive the base 1 to move. A fixing bolt 18 is threadedly connected to one end of the support rod 4, and the bolt tail of the fixing bolt 18 abuts against the connecting pipe 5. After tightening the fixing bolt 18, the connecting pipe 5 can be fixed, and after loosening the fixing bolt 18, the connecting pipe 5 can rotate on the support rod 4.

[0034] A sleeve 19 is sleeved and bearing-connected on the outer wall of the connecting tube 5. The bottom end of the sleeve 19 penetrates and is welded to the chuck 6. The chuck 6 is rotatably connected to the connecting tube 5 through the sleeve 19. When the sleeve 19 is rotated, the chuck 6 is rotated, and then the spiral wire 7 on the chuck 6 is meshed with the arc groove 10 to drive the slide bar 9 to slide in the slide rail 8. A plurality of gripping rods 20 are welded on the side wall of the sleeve 19. The gripping rods 20 are used for easy gripping. A positioning bolt 16 is threaded on the side wall of the sleeve 19. The positioning bolt 16 penetrates the sleeve 19. The bolt tail of the positioning bolt 16 abuts against the outer wall of the connecting tube 5. When the positioning bolt 16 is tightened, the sleeve 19 is fixed on the connecting tube 5. After the positioning bolt 16 is loosened, the sleeve 19 can rotate on the connecting tube 5.

[0035] The first clamping plate 11 and the second clamping plate 12 are both arc-shaped, and the arc-shaped shapes of the first clamping plate 11 and the second clamping plate 12 respectively match the outer wall and inner wall shapes of the filter element 26 of the filter 2.

A plug plate 24 is inserted into the slot 23.

[0037] A plurality of strip grooves 25 are formed on the side wall of the upper portion of the cylinder 22 . The number and position of the strip grooves 25 correspond to the number and position of the telescopic rods 21 . The output ends of the telescopic rods 21 pass through the corresponding strip grooves 25 .

[0038] Embodiment 2:

[0039] This embodiment provides a method for quickly replacing an oil filter element, and the method steps are implemented based on Embodiment 1.

[0040] A method for quickly replacing an oil filter element comprises the following steps:

[0041] (1) Connect the air intake valve 13 to the compressed air pipeline, connect the return valve 15 to the oil tank, close the oil inlet and outlet ends of the filter 2, open the air intake valve 13 and the return valve 15, return the oil to the oil tank through compressed air, close the air intake valve 13 and the return valve 15 after the return, open the exhaust valve 14, and remove the cover and the pressure plate of the filter 2. The oil in the filter 2 is pushed back into the oil tank by compressed air instead of being released into a temporary bucket, which speeds up the work efficiency and prevents the oil from spilling on the ground when being released.

[0042] (2) Move the base 1 to the vicinity of the filter 2 so that the cylinder 22 is located above the filter 2, pull out the plug plate 24, and align the bottom end of the connecting pipe 5 vertically with the center rod 28 of the filter 2.

[0043] (3) The height is adjusted by the lifting rod 3, and the angle is adjusted by rotating the connecting pipe 5 on the supporting rod 4. After adjustment, the fixing bolt 18 is tightened to insert the center rod 28 into the bottom end of the connecting pipe 5, so as to center the entire device. At this time, the universal wheel 17 can be fixed to prevent sliding. The first clamping plate 11 is located on the outside of the filter element 26 of the filter 2, and the second clamping plate 12 is located on the inside of the filter element 26 of the filter 2, so as to facilitate the clamping of the filter element 26. During the adjustment process, the bottom end of the cylinder 22 abuts against the partition 27 of the filter 2, and the cylinder 22 is held up by the partition 27. The reason for this is that the cylinder 22 is used to hold the filter element 26, and the bottom end of the cylinder 22 is inserted into the plug plate 24 to prevent oil from spilling. Therefore, the position of the plug plate 24 should be below the filter element 26. However, when clamping the filter element 26, the filter element 26 is installed on the partition 27, and the slot 23 at the bottom end of the cylinder 22 is blocked by the partition 27 and cannot be located below the filter element 26. Therefore, the cylinder 22 is designed to be movable. When clamping the filter element 26, the cylinder 22 is held up by the partition 27. When the filter element 26 is lifted, the cylinder 22 falls due to its own weight, so that the slot 23 is located below the filter element 26.

[0044] (4) Turn the gripping rod 20 to rotate the chuck 6, and then the second clamping plate 12 is moved closer to the first clamping plate 11 through the cooperation of the spiral wire 7 and the arc groove 10, so that the filter element 26 is clamped by the first clamping plate 11 and the second clamping plate 12, and the positioning bolt 16 is tightened. When the chuck 6 rotates, it can drive multiple slide bars 9 to slide at the same time, thereby clamping multiple filter elements 26 at the same time, thereby improving work efficiency.

[0045] (5) Lift the lifting rod 3 upwards, pull the filter element 26 out of the partition 27, and raise the filter element 26 to the top of the filter 2. At this time, the cylinder 22 falls due to its own weight, and the plug plate 24 is inserted into the slot 23. Push the base 1 to move to a suitable position, such as near the maintenance table, and rotate the chuck 6 in the opposite direction to make the second clamping plate 12 away from the first clamping plate 11, thereby loosening the filter element 26 and making the filter element 26 fall into the cylinder 22. In this process, the oil remaining on the filter element 26 is caught by the plug plate 24 and stored in the cylinder 22 to prevent the oil from spilling on the ground. The lifting rod 3 is lowered, and the bottom end of the cylinder 22 abuts the maintenance table, and the cylinder 22 is lifted up by the maintenance table. At this time, the telescopic rod 21 is retracted through the strip groove 25 to remove the cylinder 22.

[0046] A new filter element 26 is installed in the filter 2 , and the pressure plate and the cover of the filter 2 are installed, thereby completing the replacement of the filter element 26 .

[0047] The above-described embodiments are merely descriptions of preferred implementations of the present invention, and are not intended to limit the concept and scope of the present invention. Without departing from the design concept of the present invention, various modifications and improvements made by ordinary persons in the art to the technical solution of the present invention should fall within the scope of protection of the present invention.
