[0029] The components include: oil tank 100, inlet three-way valve 200, filter 300, main cylinder 310, annular flange 311, short flange 312, filter inner cylinder 320, oil outlet 321, snap-fit ​​part 322, groove 323, elastic element 324, filter element 330, filter cover plate 340, hook block 341, oil pump assembly 400, motor 410, oil pump 420, and outlet three-way valve 500. Detailed Implementation

[0030] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0031] like Figure 1 , 2 As shown in Figure 4, a mobile oil filling and changing device with recyclable purification includes a filtration system and an oil tank 100, wherein the oil tank 100 and the filtration system are installed on a mobile platform.

[0032] The filtration system includes an inlet three-way valve 200, an oil pump assembly 400, a filter assembly, and an outlet three-way valve 500.

[0033] One of the oil inlet ports of the three-way inlet valve 200 is connected to the oil outlet port of the oil tank 100, and the oil outlet port of the three-way inlet valve 200 is connected in sequence to the oil pump assembly 400 and the filter assembly through pipelines.

[0034] The oil outlet of the filter assembly is connected to the oil inlet of the three-way oil outlet valve 500, and one of the outlets of the three-way oil outlet valve 500 is connected to the oil inlet of the oil tank.

[0035] The design incorporates two three-way valves at the oil inlet and outlet, enabling the device to operate in two modes: with and without an oil tank. For equipment with low oil volumes, the device can be integrated with its built-in oil tank (100), allowing for oil filtration for both high and low oil volumes. For high oil volumes, the tank can be omitted, and the equipment can be directly connected to the filtration system for filtering. The addition of an oil tank and two operating modes allow for oil filtration of various equipment models.

[0036] like Figure 3 As shown, the filter assembly includes a filter 300, which includes a filter main cylinder 310, a filter inner cylinder 320, a filter element 330, and a filter cover plate 340.

[0037] The top of the filter main cylinder 310 is open. The middle part of the filter main cylinder 310 is provided with an annular flange 311 protruding towards the center along the inner wall. Above the annular flange 311, there are multiple short flanges 312 located on the same horizontal plane intermittently along the inner wall.

[0038] The filter inner cylinder 320 is fitted inside the filter main cylinder 310. The upper end of the filter inner cylinder 320 is open, and the bottom center is provided with an oil outlet 321.

[0039] The bottom of the filter inner cylinder 320 is provided with a snap-fit ​​part 322, the diameter of which is not greater than the inner diameter of the annular flange 311; the snap-fit ​​part 322 is provided with multiple snap-fit ​​flanges along the outer side wall, and the axial constraint of the filter inner cylinder 320 is completed when the snap-fit ​​flanges are rotated between the short flange 312 and the annular flange 311.

[0040] The filter element 330 is fitted into the inner cylinder 320 of the filter, the filter cover 340 is installed on the upper end of the inner cylinder 320 of the filter, the oil inlet of the filter is installed on the upper side wall of the main cylinder 310 of the filter, the upper side wall of the inner cylinder 320 of the filter has an oil inlet, and the oil outlet of the filter is installed on the lower part of the main cylinder 310 of the filter.

[0041] The filter main body 310, filter inner body 320, and filter element 330 are installed sequentially, and the filter cover 340 is installed by a screw-on method. Compared with the current screw-on method, the filter 300 of this solution is more convenient to replace the filter element. The filter main body 310 of the device is fitted with the snap-fit ​​part 322 through the annular flange 311, which divides the internal space of the filter main body 310 into two. Then, the short flange 312 is staggered with the snap-fit ​​flange to constrain the axial freedom of the filter inner body 320. This assembly method is conducive to the disassembly and maintenance of the device.

[0042] In addition, the top side wall of the filter inner cylinder 320 is provided with a plurality of grooves 323, the grooves 323 including vertical sections and horizontal sections. The vertical sections are opened downward from the upper end of the filter inner cylinder, and the horizontal sections are opened to one side along the inner cylinder after the vertical sections.

[0043] The filter cover plate 340 is provided with a hook block 341 that matches the groove. The hook block 341 includes a vertical part and a horizontal part. The width of the horizontal part is not greater than the width of the vertical section of the groove. The length of the vertical part is similar to the length of the vertical section. The height of the horizontal part is less than the height of the horizontal section of the groove.

[0044] The filter inner cylinder 320 and the filter cover 340 are assembled through the groove 323 and the hook block 341. When installing the filter cover 340, simply place the filter cover 340 over the inner filter inner cylinder 320 and rotate the filter cover 340 so that the horizontal part of the hook block 341 is rotated to the horizontal section of the groove 323. This design also facilitates the later opening of the filter cover 340 for maintenance of the inside of the filter inner cylinder 320.

[0045] In addition, it also includes an elastic element 324, which is installed at the bottom of the filter inner cylinder 320.

[0046] The function of the elastic element 324 is to lift the filter element 330 upwards, making it convenient to remove the filter element 330 during maintenance.

[0047] In addition, the top of the filter cover 340 is provided with an air outlet, and the air outlet is fitted with a plug.

[0048] Because the gap between the filter cover plate 340 and the filter inner cylinder 320 is filled with oil, the air that enters when the filter cover plate 340 is closed cannot be discharged. Therefore, the gas inside the filter cover plate 340 will affect the installation of the filter cover plate 340. Opening the vent hole to make the internal and external atmospheric pressure equal will facilitate the installation of the filter cover plate 340.

[0049] As a supplement to the above technologies, such as Figure 4 As shown, the filter assembly further includes a primary filter 600, which is installed upstream of the oil pump assembly 400, and at least one set of filters is installed downstream of the oil pump assembly 400.

[0050] In addition, the oil pump assembly 400 includes a motor 410 and an oil pump 420. The moving platform is provided with a vertical support frame. The motor 410 is vertically fixed to the support frame. The oil pump 420 is mounted on the support frame. The motor 410 drives the oil pump.

[0051] The support frame is equipped with a motor controller, and the signal acquisition terminal of the motor is connected to the signal output terminal of the motor controller.

[0052] In addition, the mobile platform is equipped with a trolley handle, and the bottom of the mobile platform is equipped with multiple casters.

[0053] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without any inventive effort, and these embodiments will all fall within the scope of protection of this utility model.
