Detailed Implementation

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] like Figure 1-4As shown, a lubricating oil filtration device with backflushing function includes a base plate 1, a filter 2, a main pump body 3, an inlet pipe 4, and an outlet pipe 5. A backflushing mechanism 7 is provided at the upper end of the base plate 1. The backflushing mechanism 7 includes a water storage tank 71 fixedly connected to the upper end of the base plate 1. A connecting pipe 72 is fixedly connected to the rear end of the water storage tank 71. A valve 73 is installed at the upper end of the connecting pipe 72. A secondary pump body 76 is installed at one end of the water storage tank 71. A return flow chamber 77 is installed at one end of the secondary pump body 76. A mounting bracket 78 is fixedly connected to the inner wall of the return flow chamber 77. A filter element 79 is slidably connected to the inner side of the mounting bracket 78. A fixing plate 710 is fixedly connected to the upper end of the filter element 79. A connecting pipe 711 is fixedly connected to one end of the return flow chamber 77.

[0021] In this embodiment, a second valve 75 is installed at the rear end of the connecting pipe 711, a mounting base 74 is fixedly connected to the lower end of the auxiliary pump body 76, the connecting pipe 72 is connected to the water storage tank 71, the lower end of the mounting base 74 is fixedly connected to the upper end of the base plate 1 near the water storage tank 71, the auxiliary pump body 76 is connected to the water storage tank 71, the auxiliary pump body 76 is connected to the return chamber 77, the lower end of the filter element 79 is in contact with the inner bottom of the return chamber 77, the lower end of the fixing plate 710 is in contact with the upper end of the return chamber 77 near the outer side of the filter element 79, the connecting pipe 711 is connected to the return chamber 77, and the lower end of the return chamber 77 is fixedly connected to the upper end of the base plate 1 near the mounting base 74.

[0022] Specifically, if foreign matter accumulates inside filter 2 after prolonged use, the pipe containing lubricating oil should be shut off, and the discharge pipe 5 should be closed. Then, valves 73 and 75 should be opened, and the main pump 3 and auxiliary pump 76 should be started. The main pump 3 will draw the cleaning fluid from the water storage tank 71 through the connecting pipe 72 and discharge it into filter 2, thus cleaning the inner wall of filter 2. The cleaning fluid then flows back into the discharge pipe 5, and through the connecting pipe 711 into the return chamber 77. At this point, the auxiliary pump 76 will draw out the cleaning fluid, and during this process, the cleaning fluid will pass through the filter element 79, filtering out any foreign matter in the cleaning fluid. Simultaneously, the auxiliary pump body 76 discharges the cleaning fluid into the water storage tank 71, which facilitates the next flushing of the filter 2. Then, the fixing plate 710 is pulled, causing the fixing plate 710 to drive the filter element 79 to slide upward within the mounting bracket 78, thus cleaning the filter element 79. By discharging the cleaning fluid from the water storage tank 71 into the filter 2, flushing the filter 2 with the cleaning fluid, and then returning the cleaning fluid to the return tank 77 and filtering it through the filter element 79, the cleaning fluid is discharged back into the water storage tank 71. This facilitates the flushing of the filter 2, thereby preventing excessive foreign matter from adhering to the filter 2 and improving the efficiency of the filter 2 in filtering lubricating oil.

[0023] In this embodiment, the filter 2 is installed on the upper end of the base plate 1 near the rear side of the water storage tank 71, the main pump body 3 is installed at one end of the filter 2, the inlet pipe 4 is installed at one end of the main pump body 3, the outlet pipe 5 is installed at the other end of the base plate 1, the lower end of the base plate 1 is fixedly connected with a caster wheel 6, the upper end of the first valve 73 is installed at the lower end of the inlet pipe 4, and the rear end of the second valve 75 is installed at the front end of the outlet pipe 5.

[0024] Specifically, with valve 73 and valve 75 closed, the pipe containing lubricating oil is connected to the inlet pipe 4, and the main pump body 3 is started. The main pump body 3 draws the lubricating oil out of the inlet pipe 4 and discharges the lubricating oil into the filter 2, whereby the filter 2 filters the lubricating oil, and the filtered lubricating oil is discharged through the outlet pipe 5.

[0025] Working principle:

[0026] In use, first, with valve 73 and valve 75 closed, connect the pipe containing lubricating oil to the inlet pipe 4. Then, start the main pump 3, which draws lubricating oil from the inlet pipe 4 and discharges it into the filter 2. The filter 2 then filters the lubricating oil, and the filtered lubricating oil is discharged through the outlet pipe 5. If foreign matter accumulates in the filter 2 after prolonged use, disconnect the pipe containing lubricating oil, close the outlet pipe 5, and open valves 73 and 75. Then, start the main pump 3 and the auxiliary pump 76. The main pump 3 draws the cleaning fluid from the water storage tank 71 through the connecting pipe 72 and discharges it into the filter 2. This cleans the inner wall of the filter 2, and the cleaning fluid then flows back into the outlet pipe 5, allowing it to flow through the connecting pipe 711 to the return flow. Inside chamber 77, the auxiliary pump 76 then draws out the cleaning fluid. During the drawing process, the cleaning fluid passes through the filter element 79, allowing foreign matter in the cleaning fluid to be filtered out by the filter element 79. At the same time, the auxiliary pump 76 discharges the cleaning fluid into the water storage chamber 71, which facilitates the next flushing of the filter 2. Then, the fixing plate 710 is pulled, causing the fixing plate 710 to slide the filter element 79 upward within the mounting bracket 78, thus cleaning the filter element 79. By discharging the cleaning fluid from the water storage chamber 71 into the filter 2, flushing the filter 2 with the cleaning fluid, and then returning the cleaning fluid to the return chamber 77 and filtering it through the filter element 79 before discharging it back into the water storage chamber 71, the purpose of flushing the filter 2 can be achieved, thereby avoiding excessive foreign matter in the filter 2 and improving the efficiency of the filter 2 in filtering lubricating oil.
