Description

Technical Field

[0001] The utility model relates to a filtering device, in particular to a working vehicle type hydraulic oil filtering device. Background Art

[0002] Hydraulic oil is the key working medium in the hydraulic system. It transmits energy, lubricates components, cools the system and prevents rust and corrosion.

[0003] Usually, after hydraulic oil has been used for a period of time, impurities will exist in the hydraulic oil, which will affect the service life of the equipment. The impurities in the hydraulic oil can be used again after filtering.

[0004] However, the existing filtering structure is set on a work vehicle, that is, the filtering structure is moved to the side of the equipment by the work vehicle, and then the hydraulic oil is filtered through the filtering structure. When filtering through the filtering structure, it is centralized filtering, that is, the hydraulic oil is added to the filter box for unified filtering, which leads to low filtering efficiency of the hydraulic oil. In addition, centralized filtering will also cause the filtering structure to be easily clogged, affecting the subsequent filtering effect of the hydraulic oil. Utility Model Content

[0005] The main purpose of the utility model is to provide a work vehicle type hydraulic oil filtering device to solve the above-mentioned problems.

[0006] In order to achieve the above purpose, the utility model provides a work vehicle type hydraulic oil filtering device, including a mobile vehicle, a box, a filtering structure and a diversion part.

[0007] The box body is movably arranged on a mobile vehicle through a transverse moving member, the upper end of the box body is provided with an oil inlet, the lower end of the box body is a tapered portion, and the lower end of the tapered portion is provided with an oil outlet;

[0008] The filter structure is arranged in the middle of the box body, and the filter structure has three groups. The three groups of filter structures are arranged in parallel in the box body. The filter structure includes an upper filter frame and a lower filter frame. The upper filter frame is provided with three layers of filter screens. The lower end of the upper filter frame is provided with a conical outlet. The lower filter frame is provided with multiple filter elements. The lower end of the lower filter frame is provided with multiple circular outlets, and the multiple circular outlets correspond to the multiple filter elements.

[0009] The diverter is connected to the lower end of the oil inlet, and is used to add hydraulic oil into the three upper filter frames respectively.

[0010] The above-mentioned beneficial effect is that this equipment is moved to the required position by the action of the mobile vehicle, and through the action of the horizontal moving part, the box is moved horizontally on the mobile vehicle, and the position of this filtering structure is adjusted, and then the hydraulic oil enters the diversion part from the oil inlet, and the hydraulic oil enters the three upper filter frames respectively through the diversion part, and the impurities of different particle sizes in the hydraulic oil are filtered out through the three layers of filter mesh in the upper filter frame, and the filtered hydraulic oil falls into the lower filter frame from the conical outlet. At this time, the multiple filter elements in the lower filter frame finely filter the hydraulic oil again to remove smaller particles and pollutants in the hydraulic oil. Then, the finely filtered hydraulic oil falls from the circular outlet into the conical part and is discharged from the oil outlet. In this way, each filtering structure can play a role independently, and at the same time, it can also share the flow of hydraulic oil, handle a larger flow, and will not interfere with each other, thereby improving the overall filtering efficiency. At the same time, the filtering structure is not easy to be blocked, and the filtering effect will be better.

[0011] A preferred solution is that the mesh openings on the three layers of filter screens are gradually smaller.

[0012] A preferred solution is that two support rods are respectively provided on both sides of the box body.

[0013] A preferred solution is that the three lower filter frames are connected by a fixing plate, and both ends of the fixing plate are connected to the inner wall of the box body.

[0014] A preferred solution is that a control valve is provided on the oil outlet.

[0015] A preferred solution is that the diversion part includes a diversion frame, a first diversion pipe, a second diversion pipe, and a third diversion pipe. The upper ends of the first diversion pipe and the second diversion pipe are respectively connected to the two sides of the diversion frame, the lower end of the oil inlet is connected to the upper end of the diversion frame, and the third diversion pipe is connected to the lower end of the diversion frame. The lower ends of the three diversion pipes are respectively arranged on the upper sides of the three upper filter frames.

[0016] A preferred solution is that the lateral moving parts have two groups, and both groups of the lateral moving parts include a screw rod and a moving block. The screw rod is arranged in a groove at the upper end of the moving vehicle, and the moving block is arranged on the screw rod. The upper end of the moving block is connected to the lower end of the support rod. BRIEF DESCRIPTION OF THE DRAWINGS
