[0024] Example:

[0025] like Figure 1-4As shown, in this embodiment, the filtering device 1 is used to be connected to the hydraulic system 2, and the filtering device 1 includes an oil barrel 11 for containing oil and a pipeline assembly, the pipeline assembly is used to connect the hydraulic system 2 and the oil barrel 11 as a whole, and a filtering assembly 12 with a valve port is provided in the pipeline assembly; the valve port is used to allow the oil to circulate between the oil barrel 11 and the filtering assembly 12, or to allow the oil to circulate between the oil barrel 11, the filtering assembly 12 and the hydraulic system 2; the pipeline assembly is also connected to a detector 14, and the detector 14 is used to detect the cleanliness of the filtered oil.

[0026] Specifically, the hydraulic system of this embodiment may refer to a hydraulic system specifically used for filtering. The filtering device 1 of this embodiment can be connected to the hydraulic system 2 to form a circulation pipeline, so that the particulate matter in the oil can be filtered through the filter component 12 in the pipeline to complete the oil cleaning, and the cleaning efficiency is high, and there is no need to replace the oil, which can greatly reduce labor costs and avoid waste of oil resources. Through the optimized use of pipeline layout and valve ports in the pipeline assembly, the filtering device 1 can not only perform self-circulation filtration of the oil inside the equipment, but also communicate with the hydraulic system 2 to clean the hydraulic system 2, which is easy to use. In addition, the present embodiment is also provided with a detector 14, through which it can be judged whether the cleanliness of the oil meets the requirements, so that the working process of the equipment can be controlled more accurately, and the working efficiency of the filtering device 1 and the hydraulic system 2 can be improved. In some specific embodiments, the detector 14 in the circulation pipeline can be set before the filter component 12, or it can be set after the filter component 12, and the detector 14 can also be set in the pipeline before and after the filter component 12, so as to realize the detection of the oil before or after filtration, or the detection of the oil before and after filtration, so as to further judge and process, which is not limited here.

[0027] In this embodiment, an oil pump 13 is installed in the pipeline assembly, and the oil pump 13 is located between the filter assembly 12 and the oil barrel 11. The valve port includes a first multi-way valve 121 and a second multi-way valve 122, and the first multi-way valve 121 is used to make the arriving oil flow to the second multi-way valve 122 or the hydraulic system 2; the outlet of the detector 14 is connected to the oil barrel 11, and the second multi-way valve 122 is used to receive the oil from the first multi-way valve 121 or the hydraulic system 2, and to make the arriving oil flow partially to the oil barrel 11 and partially reach the detector 14.

[0028] Specifically, Figure 2 and 3As shown, the filter assembly 12 also includes a filter 123, which can be a replaceable filter element and can finely filter the oil. The filter 123 can be installed between the oil pump 13 and the first multi-way valve 121. The oil pump 13 can be an oil pump 13 with a safety valve, which can suck the oil in the oil barrel 11 into the filter 123. The oil reaches the first multi-way valve 121 after being filtered by the filter 123; the oil can be transmitted to the hydraulic system 2 or the second multi-way valve 122 by adjusting the steering direction of the multi-way valve, so that the oil can directly reach the second multi-way valve 122 or first work in the hydraulic system 2 with the hydraulic element 21 before reaching the second multi-way valve 122, as shown in FIG. Figure 2 As shown, each output port is respectively provided with a control valve, and the first multi-way valve 121 may include valve 1 and valve 2. After the oil reaches the first multi-way valve 121, if valve 1 is opened, the oil can directly reach the second multi-way valve 122; after the oil reaches the second multi-way valve 122, under the regulation of the second multi-way valve 122, a part of the oil directly flows back to the oil barrel 11, and the other part of the oil is transported to the detector 14, so as to judge whether the cleanliness of the oil meets the relevant requirements through the detector 14; thereby realizing self-circulating filtration of the oil in the oil barrel 11. After the oil reaches the first multi-way valve 121, if the valve 2 is opened, the oil can enter the power unit 3 of the operating bed and the hydraulic system 2 and then reach the second multi-way valve 122. After the oil reaches the second multi-way valve 122, under the regulation of the second multi-way valve 122, part of the oil flows directly back to the oil barrel 11, and the other part of the oil is transported to the detector 14 to determine whether the cleanliness of the oil meets the relevant requirements through the detector 14, thereby achieving filtering of the hydraulic system 2.

[0029] In a specific embodiment, the first multi-way valve 121 is provided with multiple output ports corresponding to multiple hydraulic systems 2 and / or multiple hydraulic elements 21 of a single hydraulic system 2, and each output port is connected to each hydraulic element 21 in a one-to-one correspondence; the second multi-way valve 122 is provided with multiple receiving ports corresponding to multiple hydraulic elements 21, and each receiving port is connected to each hydraulic element 21 in a one-to-one correspondence. Specifically, the hydraulic system 2 may include multiple hydraulic elements 21, so that one output valve port of the multi-way valve is connected to the oil inlet of one hydraulic element 21, and each output port is provided with a control valve; Figure 4 The figure shows the circulating flow path of the oil in the filtering system when the filtering system cleans a single hydraulic component. The oil return port of the hydraulic component 21 is connected to the receiving port of the second multi-way valve 122, so that the single hydraulic component 21 can be circulated and filtered, and whether the cleanliness of the single hydraulic component 21 is up to standard can be checked, which is beneficial to reducing the risk of damage to the hydraulic component 21, extending the service life of the hydraulic component 21 and hydraulic oil, and reducing the cost of use.

[0030] Furthermore, in this embodiment, the second multi-way valve 122 is connected to the oil barrel 11 through a first pipe, and the second multi-way valve 122 is connected to the detector 14 through a second pipe, and the diameter of the first pipe is larger than the diameter of the second pipe. The diameter of the first pipe is relatively large, which can reduce the back pressure of the return flow; the flow rate required for the detector to detect is small, so the second pipe with a relatively small diameter can meet the demand, and the oil can flow back to the oil barrel 11 after the detector 14 completes the detection.

[0031] In this embodiment, the detector 14 can monitor and analyze the particle size, cleanliness and even pollutants of the oil. The detector 14 can directly display the cleanliness level, or can communicate with an external electronic device to display the cleanliness level through the external electronic device. Further, in some specific embodiments, the filter device 1 is also provided with a control box 15, and the filter assembly 12 and the detector 14 can be installed in the control box 15. The control box 15 is also provided with an observation window 151, and the reading of the detector 14 can be viewed through the observation window 151. In this embodiment, a liquid level meter 111 and a refueling port 112 are installed on the oil barrel 11. The change of the oil amount in the oil barrel 11 can be observed through the liquid level meter 111, and the refueling port 112 can be used to add oil.

[0032] In this embodiment, the filter device 1 further includes a base 16, and the oil drum 11, the oil pump 13, the filter assembly 12 and the detector 14 are all fixed on the base 16, that is, the oil drum 11, the oil pump 13 and the control box 15 are all fixed on the base 16, and casters 161 are installed at the bottom of the base 16, so that it is more convenient to move and transport the filter device 1. Furthermore, a handrail 17 is also installed on the base 16 to facilitate the user to push and pull the filter device 1 during the movement.

[0033] In this embodiment, the filtering system includes a hydraulic system 2 filtering device 1, and the hydraulic system 2 is connected to the filtering device 1. The hydraulic system 2 can be the hydraulic system 2 of the operating bed. The hydraulic system 2 includes hydraulic control elements, hydraulic elements 21 and pipelines and other devices, wherein the hydraulic element 21 includes an oil pump, a control element and an actuator. Through the cooperation between these components, the bed state of the operating bed can be controlled and adjusted. The hydraulic system 2 in the filtering system can be set up in one or more, that is, in some specific embodiments, multiple output ports and multiple receiving ports can be configured in the pipeline assembly of the filtering device 1, so that the filtering device 1 can clean multiple operating bed hydraulic systems 2 at the same time, and the working efficiency is high. Of course, in some other embodiments, the hydraulic system 2 can also refer to the hydraulic system on other mechanical equipment, which is not limited here.

[0034] Furthermore, in this embodiment, a power unit 3 is also provided between the hydraulic system 2 and the filtering device 1. The power unit 3 is installed on the operating bed and is used to provide power for the hydraulic system 2. Specifically, the power unit 3 includes structures such as a motor, a power pump, a relief valve, and an oil tank, which can provide power for the control elements and actuators of the hydraulic system 2, so that the oil can flow smoothly from the first multi-way valve 121 to the hydraulic system 2. In this embodiment, the power unit 3 of the operating bed includes an oil tank. When it is necessary to add clean oil to the operating bed equipment, the output port of the first multi-way valve 121 is connected to the oil tank, and the corresponding valve is opened to add clean oil to the operating bed. The operation is simple and convenient.
