A filtering device is installed inside the filter chamber 3, and the filtering device includes a plurality of filter screens 5 from top to bottom. In this embodiment, three filter screens 5 are used, and the meshes of the three filter screens 5 decrease from top to bottom. By setting a plurality of filter screens 5, the lubricating oil is filtered multiple times to improve the filtering effect. An oil delivery pipe 302 is provided at the bottom of the side wall of the filter chamber 3, which is used to deliver the filtered lubricating oil to the storage chamber 4 for storage.

[0032] The side wall of the filter chamber 3 is provided with three openings, and one end of the three filter screens 5 passes through an opening and is installed inside the filter chamber 3. Two opposite inner walls of the filter chamber 3 are provided with slide grooves, and both sides of the filter screens 5 are slidably connected in the slide grooves. Figure 3 As shown, a sealing plate 6 is provided at one end of the filter screen plate 5, and the sealing plate 6 is located outside the filter chamber 3. The filter screen plate 5 is fixedly installed in the middle position of the sealing plate 6. Bolts 601 are respectively provided on the four corners of the sealing plate 6, and the sealing plate 6 is fixed to the outer wall of the filter chamber 3 through the bolts 601. A plurality of plug blocks 602 are provided on the side wall of the sealing plate 6 close to the filter screen plate 5, and a slot opposite to the plug block 602 is provided on the outer wall of the filter chamber 3, and the plug block 602 is inserted into the slot.

A mounting plate 202 is fixed to the upper part of the side wall of the storage chamber 4, and a vacuum assembly 8 is fixed to the mounting plate 202, which is used to extract the air inside the storage chamber 4 and extend the storage time of the lubricating oil. The vacuum assembly 8 can be a vacuum pump sold on the market.

[0036] An oil filling pipe 403 is provided at the top of the storage chamber 4, and a sealing cover 404 is provided at the oil filling pipe 403. When the lubricating oil in the storage chamber 4 is used up and there is no lubricating oil to be filtered, lubricating oil can be directly added to the storage chamber 4 through the oil filling pipe 403, so that it can be used as a storage container. A plurality of temperature sensors 405 are provided on the inner wall of the storage chamber 4 for detecting the temperature of the stored lubricating oil.

[0037] Independently controlled electric heating elements 9 are respectively provided inside the side walls of the filter chamber 3 and the storage chamber 4.

[0038] The method of using the lubricating oil storage and treatment system provided in this embodiment is as follows: the lubricating oil to be filtered is added into the filter chamber 3 through the oil inlet pipe 301. After the lubricating oil passes through multiple filter screens 5 to filter out impurities, the vacuum assembly 8 is turned on to extract the air inside the storage chamber 4, and then the air is transported to the inside of the storage chamber 4 through the oil pipe 302 and the oil pump 7. When the lubricating oil inside the storage chamber 4 needs to be taken, a container is placed at the oil extraction branch pipe 402, and the valve on the oil extraction branch pipe 402 is opened.

[0039] Example 2

[0040] A lubricating oil storage and treatment system, such as Figure 4 As shown, the technical solution in this embodiment is basically the same as that in Embodiment 1, except that: a first stirring device is provided inside the filter chamber 3 in this embodiment, and a second stirring device is provided inside the storage chamber 4.

[0041] A first stirring device is arranged above each filter screen plate 5 of the filter chamber 3, and the first stirring device comprises a first stirring shaft 11 arranged horizontally, and a plurality of first stirring blades 1101 are arranged on the first stirring shaft 11, and a mounting plate is fixed to the outside of the side wall of the filter chamber 3 opposite to the partition plate 201, and a first drive motor 10 is fixed to the mounting plate, and the output shaft of the first drive motor 10 passes through the side wall of the filter chamber 3 and is connected to the first stirring shaft 11. The lubricating oil is stirred by the first stirring device, so that impurities are more easily separated from the lubricating oil, and the filtering speed is improved.

[0042] The second stirring device includes a second stirring shaft 13 arranged vertically, and a plurality of second stirring blades 1301 are arranged on the second stirring shaft 13. A second driving motor 12 is installed on the top of the storage chamber 4, and the output shaft of the second driving motor 12 passes through the top wall of the storage chamber 4 and is fixed to the top of the second stirring shaft 13.

[0043] Example 3

[0044] A lubricating oil storage and processing system, the technical solution in this embodiment is basically the same as that in embodiment 2, except that: the connection method between the oil filling pipe 403 and the sealing cover 404 is different.

[0045] like Figure 5 As shown, the sealing cover 404 in this embodiment includes a disc 4041, a protrusion 4042 is fixed at the bottom of the disc 4041, the diameter of the protrusion 4042 is consistent with the inner diameter of the oil filling tube 403, and the protrusion 4042 is inserted into the oil filling tube 403; a vertical cavity 4031 is provided inside the side wall of the oil filling tube 403, a slider 4032 is slidably connected in the cavity 4031, the slider 4032 can slide up and down, and a connecting shaft 4033 is rotatably connected to the slider 4032, and the top end of the connecting shaft 4033 passes through the top wall of the cavity 4031 and is fixed to the bottom of the disc 4041. Figure 6 As shown, when in use, the disc 4041 is pulled upward, and the disc 4041 drives the slider 4032 to move upward through the connecting shaft 4033. When the protrusion 4042 moves to the top of the oil filling pipe 403, the disc 4041 is rotated to rotate the protrusion 4042 to the side of the oil filling pipe 403, and then the disc 4041 is pressed downward to make the slider 4032 drop to the lowest point, so that the oil filling pipe 403 is opened, and lubricating oil can be added to the inside of the storage chamber 4 through the oil filling pipe 403. The connection method of the sealing cover 404 and the oil filling pipe 403 provided in this embodiment can prevent the sealing cover 404 from being lost.

[0046] The lubricating oil storage and processing system provided by the present invention divides a box into a filter chamber and a storage chamber. The lubricating oil is directly stored after filtering and will not come into contact with air during the transfer process, thereby avoiding lubricating oil contamination. The storage chamber is provided with a vacuum pumping component, which can extend the storage time of the lubricating oil. The structure is simple and the operation is convenient, which helps to greatly improve the utilization rate of the recyclable lubricating oil.
