Description

Technical Field

[0001] The utility model belongs to the technical field of hydraulic oil tank filtering, and particularly relates to a filtering system with a built-in hydraulic oil tank. Background Art

[0002] The built-in hydraulic oil tank filtering system is a purification device integrated inside the hydraulic system tank, which is designed to continuously remove impurities and contaminants in the oil to ensure the stability and efficiency of the hydraulic system operation. In the prior art, an oil suction port and an oil outlet are usually set at the hydraulic oil tank, and a detachable filter element is set at the oil suction port and the oil outlet to filter the hydraulic oil. However, in this method, a cleaning component for cleaning the filter element is not set in front of the filter element. During the circulation of the hydraulic oil, the filter element will gradually accumulate contaminants. If there is no cleaning component, the filter element is easy to be blocked, affecting the normal flow of the oil and reducing the filtering efficiency. At the same time, frequent maintenance and replacement of the filter element will interrupt the normal production process and affect the execution of the production plan.

[0003] For example, the utility model with announcement number CN221054064U discloses a hydraulic oil tank filtering system and a tractor. In the technical solution of this patent, a mounting frame is provided inside the hydraulic oil tank, and a return oil filter element is detachably provided inside the mounting frame. An oil inlet is provided on the other side of the hydraulic oil tank, and an oil inlet filter element is provided at the oil inlet to filter the hydraulic oil. However, in this method, no cleaning component for cleaning the filter element is provided in front of the filter element, which means that the filter element is directly facing the pollutants in the oil tank, which is prone to quickly accumulate impurities and become clogged, shortening the maintenance cycle and requiring more frequent shutdowns to replace or disassemble and clean the filter element, which not only increases maintenance costs but also may lead to reduced production efficiency. Utility Model Content

[0004] In view of this, the utility model aims at the deficiencies of the prior art and provides a filtering system with a built-in hydraulic oil tank, which can not only filter the hydraulic oil through filter plates one and two to effectively reduce pollutants in the circulating oil, but also through the cleaning component at the left end of filter plate one, when filter plate one is blocked, filter plate one can be cleaned to ensure unimpeded flow of hydraulic oil, thereby improving the overall working efficiency of the hydraulic system.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: a filtering system with a built-in hydraulic oil tank, including a hydraulic oil tank, an oil suction port is opened at the lower left end of the hydraulic oil tank, an oil suction pipe is arranged at the oil suction port, an oil return port is arranged at the right upper end of the hydraulic oil tank, an oil return pipe is arranged at the oil return port, the oil suction pipe and the oil return pipe are both located inside the hydraulic oil tank, grooves are symmetrically arranged inside the oil suction pipe, a filter plate 1 is connected between the two grooves, and a cleaning component for cleaning the filter plate 1 is arranged at the left end of the oil suction pipe.

[0006] As a further improvement of the utility model, the cleaning assembly includes slide grooves symmetrically opened on the side walls of the oil suction pipe, a sliding frame is slidably connected between the two slide grooves, a rotating rod is rotatably connected inside the sliding frame, brush plates are evenly arranged on the rotating rod, the brush plates are in conflict with the left side wall of the filter plate, a driving member 1 for driving the movable frame to move up and down is arranged at the upper end of the oil suction pipe, and a driving member 2 for driving the rotating rod to rotate is arranged on the left side wall of the groove.

[0009] As a further improvement of the utility model, a support base is provided at the lower end of the hydraulic oil tank, and anti-slip stripes are provided on the bottom outer wall of the support base.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows:

Brush plates 204 are evenly arranged on the rotating rod 203, and the brush plates 204 are in conflict with the left side wall of the filter plate 104. A driving member 1 for driving the movable frame to move up and down is arranged on the upper end of the oil suction pipe 102, and a driving member 2 for driving the rotating rod 203 to rotate is arranged on the groove side wall on the left side.

[0023] like Figure 1 , 2 As shown in Figure 3, the driving member 1 includes an installation box 205 arranged at the upper end of the oil suction pipe 102, and a telescopic push rod 206 is fixedly arranged inside the installation box 205.
