DETAILED DESCRIPTION

[0017] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0018] See also Figure 1-3The utility model provides a technical solution: a portable oil filter machine, including a frame 3, a filter 1 and an oil suction pump 2. The oil suction pump 2 is tiltedly arranged on the frame 3. The tilted structural design of the oil suction pump 2 can reduce the size of the equipment, save space, and be easy to carry. The equipment is powered by the oil suction pump 2 to extract the medium to be filtered and enter the filter 1 to achieve the filtering purpose. The filter 1 is fixed on the left side of the frame 3. The filter 1 can select different precisions according to the use requirements. The filter 1 is equipped with a transmitter. When the transmitter sends a signal, the filter element should be replaced in time to ensure the precision to avoid damage to the system. The outlet of the oil suction pump 2 is connected to a three-way ball valve 8, and the oil circuit can be switched through the three-way ball valve 8. The oil filter has two functions, namely filtering the oil circuit and not filtering the oil circuit, to meet people's usage needs. The inlet of the oil suction pump 2 is connected to the oil suction filter element 5 through the connecting pipe 2 15. When the pollutant particles in the oil medium are large and the pollution degree is serious, the oil suction filter element 5 can be used for primary filtration, which protects the subsequent system components, prolongs the service life and reduces the economic cost. One of the interfaces of the three-way ball valve 8 is connected to the inlet on one side of the filter 1 through the connecting pipe 1 9, and the other side of the filter 1 is set to the outlet 2 11, and the other interface of the three-way ball valve 8 is set to the outlet 1 4. When it is necessary to fill without filtering, the medium can be discharged directly from the outlet 1 4 without passing through the filter 1 by switching the three-way ball valve 8.

[0019] The frame 3 is welded by steel plates. The frame 3 is set as a hollow structure. The oil suction pump 2 is fixed to the frame 3 by bolts. While ensuring the strength, the weight is light, and a reinforcing plate 10 is set on the frame 3.

[0020] A bracket 7 is connected to the frame 3 by screws, and a handle 6 is fixed to the bracket 7. The handle 6 is a foldable handle, and the handle 6 can be held and moved, making the operation convenient and applicable to different scenes.

[0021] A lug plate 12 is provided on the left side of the frame 3 , and the filter 1 is fixed on the lug plate 12 by screws.

[0022] Long holes 13 are respectively provided on both sides of the frame 3. While ensuring the structural strength, the overall weight of the device is reduced by the long holes 13. A grounding device 16 is provided at the lower part of the frame 3. When the liquid passes through the glass fiber filter material in the filter 1, static electricity is generated. The grounding device 16 plays an anti-static role, so that the device can be used in special anti-static places.

[0023] Working principle: outlet 2 11 is the outlet of oil when filtering is required. At this time, the oil is filtered through filter 1. The filtered oil circuit: oil suction filter element 5-oil suction pump 2-three-way ball valve 8-connecting pipe 19-filter 1-outlet 2 11. Outlet 14 is a separate filling and pumping interface that does not require filtering. The unfiltered oil circuit: oil suction filter element 5-oil suction pump 2-three-way ball valve 8-outlet 14. When only filling is required without filtering, the three-way ball valve 8 can be switched to prevent the medium from passing through filter 1 and being discharged directly from outlet 14.

[0024] The basic principles, main features and advantages of the present invention are shown and described above. Without departing from the spirit and scope of the present invention, the present invention may also be subject to various changes and improvements, which are all within the scope of the present invention to be protected.
