Description

Technical Field

[0002] The hydraulic station is a hydraulic source device or a hydraulic device including a control valve, which is composed of a hydraulic pump, a driving motor, an oil tank, a directional valve, a throttle valve, a relief valve, etc. The oil is supplied according to the flow direction, pressure and flow required by the driving device. It is suitable for various machines where the driving device is separated from the hydraulic station. The hydraulic station is connected to the driving device (cylinder or motor) with an oil pipe, and the hydraulic system can achieve various prescribed actions. Before repairing the hydraulic station, the hydraulic oil inside the hydraulic station needs to be extracted and then purified and filtered, so a hydraulic oil extraction and purification device is needed to filter and purify the hydraulic oil.

[0003] Most of the existing hydraulic oil extraction and purification devices use an internal fixed hydraulic oil filter. When impurities clog the filter, the cover needs to be removed for replacement or cleaning, which is very troublesome and can only filter impurities with a single effect. It is difficult to achieve oil-water separation for the hydraulic oil that has entered the water. Utility Model Content

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in the field of hydraulic oil purification without creative work are within the scope of protection of the utility model.

[0026] like Figure 1 and 2 As shown, the utility model provides a hydraulic oil extraction and purification device, including a device body 1: a mobile vehicle 4 is fixedly provided at the lower end of the device body 1, a first hydraulic pump 6 is fixedly provided at the upper end of one side of the device body 1, a pressure gauge 8 is fixedly provided at the upper end of the first hydraulic pump 6, a second hydraulic pump 7 is fixedly provided at the lower end of one side of the device body 1, a cover plate 5 is fixedly provided at the upper end of the device body 1 by screws, and a rubber frame 11 is movably provided inside the device body 1;

[0027] In order to be able to disassemble the rubber frame 11, a filter disassembly device 2 capable of disassembling the rubber frame 11 is provided on one side of the device body 1, which is used to seal and push the rubber frame 11 and disassemble it conveniently;

[0028] like Figure 3 and 4As shown, the filter screen removal device 2 includes a spring limit frame 24, which is fixedly arranged on one side of the device body 1, and a spring 25 is movably arranged inside the spring limit frame 24. A slide groove 21 is opened on the inner wall of the device body 1, and the rubber frame 11 is located inside the slide groove 21. A stainless steel porous mesh 22 is fixed inside the rubber frame 11. A connecting seat 23 is fixed on one side of the rubber frame 11. The connecting seat 23 is movably inserted into the groove of the spring limit frame 24. A rotating threaded bolt 26 is movably arranged in the groove of the connecting seat 23. The rotating threaded bolt 26 is threadedly connected to the thread groove on one side of the device body 1, and the rubber frame 11 and the slide groove are connected to each other. 21, when the rubber frame 11 slides into the slide groove 21, the sealing effect can be achieved by squeezing, because the connecting seat 23 on one side of the rubber frame 11 slides into the spring limit frame 24, thereby inserting the rotating threaded bolt 26, and the connecting seat 23 can be squeezed by rotating the rotating threaded bolt 26, thereby driving the rubber frame 11 to squeeze and seal. When the stainless steel porous mesh 22 needs to be replaced, wait for the hydraulic oil on the stainless steel porous mesh 22 to penetrate completely, and rotate the rotating threaded bolt 26 in the opposite direction to remove the rotating threaded bolt 26, so that the rubber frame 11 and the stainless steel porous mesh 22 can be pulled for replacement and cleaning.

[0029] Furthermore, in order to heat the hydraulic oil, an oil-water separation device 3 capable of heating the hydraulic oil is provided at the lower end of the inner wall of the device body 1, which is used to heat the hydraulic oil and evaporate the water in the hydraulic oil;

[0030] like Figure 5 As shown, the oil-water separation device 3 includes a heater 31, which is fixedly arranged on one side of the device body 1, and the output end of the heater 31 is fixedly passed through one side of the device body 1. A heating pipe 32 is fixedly arranged at the output end of the heater 31, and a fixed sleeve 33 is fixedly arranged on the outer surface of the heating pipe 32. The lower end of the fixed sleeve 33 is fixedly connected to the lower end of the inner wall of the device body 1, and an exhaust fan 34 is fixedly arranged on one side of the device body 1. The heating pipe 32 is heated by the heater 31, thereby heating the hydraulic oil at the lower end of the device body 1, so that the water evaporates and is discharged by the exhaust fan 34, thereby achieving the effect of oil-water separation.

[0031] The working principle is as follows: When the utility model is in use, the hydraulic oil that needs to be purified is extracted by the first hydraulic pump 6, and then drawn into the device body 1. The filter disassembly device 2 fixes the rubber frame 11 and the stainless steel porous mesh 22, so as to penetrate and filter the hydraulic oil. When the stainless steel porous mesh 22 is blocked, the first hydraulic pump 6 will have a pressure increase effect, thereby penetrating the pressure gauge 8. When the pressure of the pressure gauge 8 is too high, the first hydraulic pump 6 is stopped, so that the hydraulic oil remaining on the upper end of the stainless steel porous mesh 22 is infiltrated, and then the filter disassembly device 2 is used to disassemble and replace it. After the hydraulic oil is filtered, it flows into the hydraulic oil filter 10 for secondary filtration. After the filtration is completed, the oil-water separation device 3 performs oil-water separation. After the separation is completed, it is extracted by the second hydraulic pump 7.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
