[0028] Example:
[0029] Please see Figure 1 This invention provides a special oil filtration and reuse life extension device for cleaning oil, including an oil inlet 1, which is connected to an oil storage tank 2 via a pipeline. An electric pump 3 is installed on the pipeline connecting the oil inlet 1 and the oil storage tank 2. An overflow valve 4 is installed on the pipeline between the oil inlet 1 and the oil storage tank 2 at the location of the electric pump 3. A filling port 5 is provided on the outside of the oil storage tank 2, which is connected to the oil storage tank 2 and a vacuum dehydrator 7 via a pipeline. The oil inlet 1, the oil storage tank 2, and the vacuum dehydrator 7 are connected via a pipeline. An air pump 6 is installed on the oil storage tank 2 via a pipeline.

[0030] Specifically, such as Figure 1As shown, a first solenoid valve 14 and a third solenoid valve 16 are installed on the pipeline connecting the filling port 5 to the vacuum dehydrator 7. The third solenoid valve 16 is located on the pipeline connecting the oil inlet 1 to the vacuum dehydrator 7. A second solenoid valve 15 is installed on the pipeline connecting the oil inlet 1 to the oil storage tank 2. A first check valve 17 is installed on the pipeline connecting the oil storage tank 2 to the vacuum dehydrator 7. A flow sensor 25 is installed on the pipeline connecting the oil storage tank 2 and the vacuum dehydrator 7. The flow sensor 25 is located behind the first check valve 17. The pipelines connecting the oil inlet 1, oil storage tank 2, filling port 5, and vacuum dehydrator 7 are connected. The pipes connecting the devices 7 are four-way pipes. A three-way pipe is installed on the pipe connecting the four-way pipe to the vacuum dewatering device 7. The first solenoid valve 14, the second solenoid valve 15, and the third solenoid valve 16 are located on the four-way pipe, and the first check valve 17 is located on the three-way pipe. The vacuum dewatering device 7 is connected to the three-way pipe, as shown in the figure. The first solenoid valve 14, the second solenoid valve 15, the third solenoid valve 16, and the first check valve 17 are all located behind the pipes of the electric pump 3 and the overflow valve 4, which can realize the independent operation of direct filtration cleaning, heated pneumatic filtration cleaning, and filling.
[0031] Specifically, such as Figure 1 As shown, the oil storage tank 2 is equipped with a pressure sensor 18, a temperature sensor 19, a heater 20, a first pressure gauge 21, and an exhaust valve 22. The pressure sensor 18 is used to obtain the pressure inside the oil storage tank 2. When the pressure is too high or too low, the air pump 6 is controlled to stop or start according to the pre-set rules, and an alarm is triggered by a buzzer. The temperature sensor 19 is used to obtain the temperature inside the oil storage tank 2 and to control the heater 20 to turn it on or off, so as to achieve a constant oil temperature. The flow sensor 25 is used to obtain the flow rate of the oil in the pipeline and to display the flow rate and total flow in real time.
[0032] Specifically, such as Figure 1 As shown, a pressure regulating valve 23 and a second check valve 24 are installed on the pipeline between the air pump 6 and the oil storage tank 2.

[0034] Working principle:
[0035] Direct filtration and cleaning: the oil enters through the oil inlet 1, passes through the electric pump 3 to the third solenoid valve 16 on the four-way pipe, then passes through the flow sensor 25 on the three-way pipe to the vacuum dehydrator 7, from the vacuum dehydrator 7 to the coarse filter 8, from the coarse filter 8 to the micro particle amplifier 9, from the micro particle amplifier 9 to the medium filter 10, from the medium filter 10 to the adsorption fine filter 11, from the adsorption fine filter 11 to the nano membrane filter 12, and finally from the nano membrane filter 12 to the oil outlet 13, completing a series of filtration and cleaning processes;
[0036] The heated pneumatic filtration and cleaning process begins by adding the oil to be treated into the oil storage tank 2 via an electric pump 3. The oil in the oil storage tank 2 is then heated to a certain temperature. The air pump 6 is turned on, and high-pressure gas enters the second one-way valve 24 through the pressure regulating valve 23. Under the action of the high-pressure gas, the oil in the oil storage tank 2 passes through the first one-way valve 17 and then through the flow sensor 25 on the three-way pipe into the vacuum dehydrator 7. From the vacuum dehydrator 7, the oil enters the coarse filter 8, then the microparticle amplifier 9, then the microparticle amplifier 9, then the medium filter 10, then the adsorption fine filter 11, then the adsorption fine filter 12, and finally the oil outlet 13, completing a series of filtration and cleaning processes.
[0037] New oil is added through inlet 1 into electric pump 3, then through the second solenoid valve 15 on the four-way pipe into filling port 5, and then injected into the hydraulic equipment.
[0038] The pressure in the oil storage tank 2 is obtained by the pressure sensor 18. When the pressure is too high or too low, the air pump 6 is controlled to stop or start according to the pre-set rules, and an alarm is triggered by the buzzer.
[0039] The temperature inside the oil storage tank 2 is obtained through temperature sensor 19, and the temperature control heater 20 is turned on or off through temperature sensor 19 to achieve constant oil temperature. The flow rate of oil passing through the pipeline is obtained through flow sensor 25, and the flow rate and total flow are displayed in real time.
