[0020] As Figures 1-5As shown in the embodiment, the lubricating oil filtering device comprises a filtering barrel 1, a cover plate 2 arranged at the top opening of the filtering barrel 1, an oil collecting barrel 3 arranged at the bottom of the filtering barrel 1, a piston block 4 arranged in the filtering barrel 1, a slide bar 5 arranged at the inner wall of the filtering barrel 1, a sliding groove 6 arranged on the side wall of the piston block 4, a first-stage filtering assembly arranged on the surface of the piston block 4, a lead screw 7 arranged in the filtering barrel 1, a first clamping seat 8 arranged at the bottom of the filtering barrel 1, a second clamping seat 9 arranged at the bottom of the cover plate 2, a driving motor 10 arranged on the surface of the cover plate 2, an oil inlet pipe 11 arranged on the cover plate 2, an electromagnetic valve 12 arranged on the oil inlet pipe 11, a second-stage filtering assembly arranged at the bottom of the filtering barrel 1, a supporting leg 13 arranged at the bottom of the oil collecting barrel 3, and an oil outlet pipe 14 arranged at the bottom of the oil collecting barrel 3.

[0021] Optionally, the first-stage filtering assembly comprises a filtering groove 15 arranged on the surface of the piston block 4, an oil passing hole 16 arranged in the piston block 4, a one-way valve 17 arranged in the oil passing hole 16, and a filter screen 18 arranged in the filtering groove 15.

[0022] Optionally, the piston block 4 is provided with a first clamping groove 20 arranged at the bottom of the piston block 4, and a second clamping groove 21 arranged at the bottom of the piston block 4. When the piston block 4 moves up and down, it can be completely closed at the upper and lower ends of the filtering barrel, so as to filter more lubricating oil.

[0023] Optionally, the second-stage filtering assembly comprises a first conduit 22 arranged at the bottom of the filtering barrel 1, a second conduit 23 arranged outside the oil collecting barrel 3, an exhaust pipe 24 arranged on the second conduit 23, an exhaust valve 25 arranged on the exhaust pipe 24, a sealing cover 26 arranged at the lower opening of the second conduit 23, a filtering bag 27 arranged in the second conduit 23, and a connecting rod 28 arranged between the filtering bag 27 and the sealing cover 26.

[0024] Optionally, a plurality of support rods 29 are arranged at intervals on the inner wall of the oil collecting barrel 3 outside the oil discharge pipe 14 and are connected to the filter barrel 3. Through each support rod 29, the stability of the whole device can be improved, and the filter barrel can be more stably supported by the oil collecting barrel 3.

[0025] Before use, the oil inlet pipe 11 on the cover plate 2 needs to be connected to the lubricating oil production device through a pipeline, and the oil discharge pipe 14 needs to be connected to the oil storage tank through a pipeline. During use, the electromagnetic valve 12 is opened by the control device to continuously inject lubricating oil into the filter barrel 1, and at this time the piston block 4 is at the bottom of the filter barrel 1. After filling, the electromagnetic valve 12 is closed and the driving motor 10 is turned on. The output shaft of the driving motor 10 drives the screw rod 7 to rotate, thereby continuously moving the piston block 4 upward which is connected to the screw rod 7 by threads, and the piston block 4 moves vertically upward along the corresponding sliding bar 5 through each sliding groove 6. In the moving process, the lubricating oil enters each primary filter assembly, and the larger impurities in the lubricating oil are preliminarily filtered through each layer of filter screen. The filtered lubricating oil flows into the bottom of the filter barrel 1 through the one-way valve 17 and the oil passage 16. When the piston block 4 moves to the top of the filter barrel 1, the driving motor 10 is reversed to move the piston block 4 downward. In the moving process, since each one-way valve 17 is in a closed state, the lubricating oil is pressed into each secondary filter assembly. The lubricating oil enters the second conduit 23 through the first conduit 22, and is filtered for the second time by the filter bag 27, so as to enter the oil collecting barrel 3. The gas generated in the secondary filter assembly filtering process is discharged outward through the exhaust valve 25 and the exhaust pipe 24. Finally, the filtered lubricating oil flows into the oil storage tank through the oil discharge pipe 14 to be stored. It has a reasonable structure design and is easy to operate. The filtering process of the lubricating oil can be quickly completed in a short time. The impurities are effectively filtered to ensure the quality of the oil product. The filter can be replaced regularly to avoid the mixture of impurities and lubricating oil to form deposits attached to the inner wall of the device, further reducing the probability of affecting the quality of the oil product, and facilitating later cleaning and maintenance, thereby solving the problems in the prior art.
