[0002] Hydraulic oil filtration devices primarily utilize filtration technology to remove impurities and contaminants from hydraulic fluids. These impurities can originate from various sources, including mechanical wear within the hydraulic system, oil oxidation and deterioration, and external contamination. The filtration device separates solid particles, moisture, gases, and other contaminants from the oil through various mechanisms such as physical interception, adsorption, and coagulation, thereby maintaining the cleanliness of the oil.

[0003] Hydraulic oil filtration devices typically use multiple filter elements for simultaneous filtration. When a filter element malfunctions, it's difficult to immediately pinpoint which one or more elements are faulty. The system must be shut down, all filter elements removed for individual testing, maintenance, and replacement, wasting time, manpower, and resources, reducing the device's efficiency, and hindering normal operation. To address these issues, existing technologies employ auxiliary mechanisms to test the filter elements and determine the specific faulty element. However, accurately locating the faulty filter element still requires multiple testing steps, consuming considerable time and time, such as group testing and data comparison, thus impacting processing efficiency.

[0025] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] Example 1: A visual filter element troubleshooting mechanism for a hydraulic oil filtration device, please refer to... Figures 1-3 The system includes a filter tank 1, which contains a filter element. The bottom of the filter tank 1 is connected to an oil outlet branch pipe 2 that communicates with and corresponds to the filter element. An observation cup 3 is provided on the oil outlet branch pipe 2. The observation cup 3 includes a transparent channel component 31 and end caps 32 connected to both ends of the transparent channel component 31. The transparent channel component 31 communicates with the oil outlet branch pipe 2 and is used to observe the color and flow rate of the oil in the oil outlet branch pipe 2. The two end caps 32 are connected by bolts 33 to fix the transparent channel component 31 to the middle of the observation cup 3. The end caps 32 are connected to the observation cup connecting flanges 34, which are connected to the oil outlet branch pipe 2.

[0027] Based on the visual filter troubleshooting mechanism of this embodiment, without any operation of the equipment, the operator can directly observe the color and flow rate of the oil filtered by the filter element in the oil outlet branch pipe 2 through the transparent channel component 31 of the viewing cup 3, thereby determining whether the filtration function of the corresponding filter element has malfunctioned. Compared with the prior art, this mechanism eliminates the need to test the filtration function of the filter element or to group and gradually locate the faulty filter element, greatly saving the time required for troubleshooting. When an abnormality is observed, the outlet of the corresponding filter element can be immediately closed, while other filter elements continue to work normally, ensuring the working efficiency of the equipment.

[0028] As a preferred embodiment, the transparent channel component 31 of this utility model can be made of glass, plexiglass, or transparent plastic.

[0029] The overall size of the observation cup 3 of this utility model is designed to fit snugly at the bottom of the filter tank 1. It can be set to a shorter length to effectively control the height of the filter tank 1. The length of the transparent channel component 31 needs to be sufficient for staff to clearly observe the color and flow of the fluid inside.

[0030] Example 2: This example is based on Example 1. In this example, the end cap 32 has a mounting groove for installing the transparent channel component 31, and a sealing gasket connects the transparent channel component 31 and the end cap 32. By providing a mounting groove on the end cap 32 and pressing and sealing it with the sealing gasket, the function of the observation cup 3 can be satisfied, while also facilitating the replacement of the sealing gasket when it reaches the end of its service life and ages. This facilitates the maintenance of the mechanism during long-term use.

[0031] Example 3: This example is based on Example 1. In this example, the end cap 32 has threads for installing the transparent channel component 31, and the transparent channel component 31 has threads that mate with the threads of the end cap 32. A sealant layer is provided between the end cap 32 and the transparent channel component 31. This example improves the sealing performance of the viewing cup 3 by using the threaded engagement of the threads of the end cap 32 and the transparent channel component, combined with the sealant, to ensure that the mechanism will not leak during long-term use.

[0032] Example 4: This example is based on Example 1. Please refer to Example 1. Figures 1-3 In this embodiment, a branch pipe connecting flange is provided on the oil outlet branch pipe 2, which is used to cooperate with the sight glass connecting flange 34. A sight glass clamp 4 is provided around the outside of the branch pipe connecting flange and the sight glass connecting flange 34, and a clamp adjusting screw 5 is connected to the sight glass clamp 4. The two ends of the sight glass 3 are fixedly connected by the sight glass connecting flange 34 and the branch pipe connecting flange, and a flange gasket can be provided at the connection point for sealing. The sight glass clamp 4 can be locked at the connection point between the sight glass connecting flange 34 and the branch pipe connecting flange by the clamp adjusting screw 5, which can ensure the sealing performance, improve the stability of the pipeline connection, and facilitate the disassembly of the pipeline for maintenance by adjusting the clamp adjusting screw 5, thereby improving maintenance efficiency.

[0033] Example 5: This example is based on Example 1. Please refer to Example 1. Figures 1-3In this embodiment, the oil outlet branch pipe 2 is connected to the main oil outlet pipe 6, and a switch valve 7 is installed on the oil outlet branch pipe 2. As a preferred embodiment, multiple filter elements and oil outlet branch pipes 2 are evenly distributed inside the filter tank 1 and at the bottom of the filter tank 1. The positions of the multiple filter elements correspond one-to-one with the positions of the multiple oil outlet branch pipes 2, and each oil outlet branch pipe 2 is equipped with a switch valve 7. The switch valve 7 can directly control the opening and closing of the oil outlet branch pipes 2. When an abnormality is observed in the filtered oil in one of the observation cups 3, the first operation is to close the switch valve 7 of the corresponding oil outlet branch pipe 2, stopping the oil discharge from the filter element corresponding to that oil outlet branch pipe 2. The switch valves 7 of the other oil outlet branch pipes 2 remain open, thereby avoiding affecting the quality of the filtered oil from other filter elements. After the batch of hydraulic oil filtration is completed and the abnormal filter element is repaired, its corresponding switch valve 7 is reopened, and normal operation resumes.

[0034] To ensure the filtration effect within the filter tank 1, the filter elements are rationally distributed, and corresponding oil outlet branch pipes 2 and filter element clearance mechanisms are installed to complement the filter elements. Oil outlet branch pipes 2, located on both sides of the main oil outlet pipe 6 and at the end of the main oil outlet pipe 6 furthest from the outlet, are connected to the main oil outlet pipe 6 via bends 8. Oil outlet branch pipes 2 located above the main oil outlet pipe 6 are directly connected to the main oil outlet pipe 6. This pipe structure allows for a more rational arrangement of the filter elements and their corresponding oil outlet branch pipes 2 within the filter tank 1, enabling the filter tank 1 to accommodate more filter elements. Simultaneously, the surrounding distribution structure facilitates easier observation of the status within each observation cup 3 by the staff.

[0035] Example 6: This example is a hydraulic oil filtration device. Please refer to... Figure 4 The device has a visual filter element troubleshooting mechanism for hydraulic oil filtration device according to any of the above embodiments. The hydraulic oil filtration device can be equipped with corresponding oil inlet pipe, sewage outlet pipe and related drive oil pump and pressure detection mechanism, and is equipped with waste oil collection box to collect and store waste oil. This makes it convenient to suck out the waste oil and collect and store it when cleaning the waste oil container after the filtration device has filtered the waste oil.

[0036] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
