It primarily consists of a pump unit, a manifold or valve assembly, a fuel tank, an electrical box, and other components. Over time, the hydraulic oil in the station accumulates a significant amount of impurities, mostly caused by friction between mechanical components. The accumulation of these impurities within the station can negatively impact the quality of the hydraulic oil.

[0003] Referring to the utility model with announcement number CN213540931U, a filtering device for a hydraulic station is disclosed, including an oil tank; a hydraulic pump arranged on the oil tank, and the input end of the hydraulic pump is plugged into the oil tank; a filtering device is provided on the output end of the hydraulic pump; the filtering device includes a filter cartridge, the filter cartridge is provided with multiple first filter holes, and a filter cotton ring is provided in the filter cartridge.

[0004] During the implementation of this application, it was found that the technology has the following problems: although the filter cotton ring can be used to filter smaller impurities in the hydraulic oil in the above patent documents, during long-term use, the impurities in the hydraulic oil are easily attached to the filter cotton ring, which may cause the filter cotton ring to be blocked and affect the service life; and the structure of the filter cotton ring is relatively complex, with multiple filter layers and pores inside. These structures make it easier for impurities to hide in it, and it is difficult to clean the impurities generated by filtration, resulting in a poor service life.

[0005] For this purpose, an integrated hydraulic station with a filtering device is proposed. Utility Model Content

[0006] The purpose of the utility model is to provide an integrated hydraulic station with a filtering device in order to make it easier to clean impurities generated after filtration, prevent clogging, and increase service life.

[0009] The filter device includes a filter cartridge, which is fixedly connected to the inner wall of the oil tank. The outer surface of the filter cartridge is provided with a plurality of trumpet holes, and the inner diameters of the trumpet holes gradually decrease from the inside to the outside. A filter frame is fixedly connected to the inner wall of one side of the filter cartridge, and an end of the connecting pipe away from the hydraulic pump extends into the interior of the oil tank and is communicated with the internal volume of the filter frame.

[0010] The cleaning mechanism includes a motor, which is fixedly connected to the outer side of the oil tank, and the output end of the motor is fixedly connected to a rotating rod.

[0011] Furthermore, the length of the rotating plate is greater than the outer diameter of the filter frame.

[0012] Furthermore, the filter frame is made of a filter mesh with a specification of 350 meshes.

[0013] Furthermore, a drain pipe is installed on the front side of the oil tank, the internal volume of the drain pipe is connected to the internal volume of the bottom end of the oil tank, and a valve is installed on the outer surface of the drain pipe.

[0014] Furthermore, the inner bottom surface of the oil tank is inclined from all sides toward the inner opening of the drain pipe.
