For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0036] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] Reference Figure 1-3 A new type of oil filter is proposed, including: an oil filter body 1, a filter cartridge 2 arranged on the oil filter body 1 and at least one filter element 3 arranged in the filter cartridge 2, and the first fixing member 22 is sleeved on the filter element 3 to ensure that the filter element 3 remains stable during operation and prevents the position from shifting.

[0038] During the operation of the oil filter, the solid impurities in the oil will gradually settle to the bottom of the filter cartridge under the action of gravity and the filtration of the filter element. When the oil filtration is completed, the oil discharge is stopped, the slag discharge port is opened, and backwashing is performed through the pressure of the drive device (oil pump) to discharge the accumulated impurities out of the filter cartridge.

[0039] By providing a slag discharge port in the filter cartridge, impurities can be discharged in time without suspending operation, preventing blockage, reducing the need for overall disassembly of the equipment and replacement of internal components, and significantly improving work efficiency.

[0040] The first fixing member in this embodiment is a filter element bracket.

[0041] In this embodiment, through the stable support and fixation of the filter element bracket, the filter element can effectively resist the vibration and pressure changes generated during operation and prevent displacement or loosening, thereby keeping the filter element in the correct position and ensuring the filtering efficiency.

[0042] Preferably, an adjustable clamping mechanism may be used instead of a fixed filter element holder.

[0043] Specifically, the adjustable clamping mechanism allows the user to adjust according to the size and shape of the filter element to accommodate filter elements of different specifications. In addition, a spring-loaded or screw-adjustable clamping method can be introduced to make the installation and removal process more convenient.

[0044] In addition, the filter element 3 used in the utility model provides higher filtration efficiency and longer service life compared with traditional filter elements. Its axial flow design greatly reduces the pressure drop. Compared with the traditional radial flow, the axial flow makes the oil flow along the axial direction of the filter element, effectively reducing the resistance and friction of the fluid inside the filter element. In addition, the axial flow can also ensure that the oil is evenly distributed inside the filter element, avoiding the pressure increase caused by excessive local flow rate, and further reducing the pressure drop.

[0045] The filter element 3 used in the present invention generally has a larger filtering surface area than a traditional filter element. Since it is longer and deeper in shape and has a wider surface area, it can provide more filtering areas.

[0046] Among them, the filter element used in the utility model is in the shape of a long cylinder, and the filter material is evenly arranged along the inner side of the cylinder, and various materials such as fiber, synthetic material or metal mesh can be used;

[0047] This embodiment adopts an axial flow mode different from the traditional filter element, that is, the oil flows in parallel to the direction of the center pipe of the filter element, rather than the traditional radial flow, that is, flowing from the outside to the inside along the radius. This change significantly improves the filtration efficiency, allowing more uniform fluid distribution and longer contact between the fluid and the filter material;

[0048] Preferably, the utility model increases the length of the filter element 3 by 240 mm, further expanding the filtering area, extending the path length of the oil passing through the filter material, and helping to remove more particles and impurities, thereby ensuring a higher degree of cleanliness of the output oil.

[0049] Preferably, the structure of the filter element 3 used in the present invention is:

[0050] Inner layer: Uses fine glass fibers or synthetic fibers to capture tiny particles and pollutants;

[0051] Middle layer: slightly coarser fiber material or metal mesh is used to intercept larger particles and reduce the burden on the inner layer;

[0052] Outer layer: Use a large-mesh metal mesh, which is mainly used to support and protect the inner layer material to prevent physical damage under high traffic.

[0053] In addition, in addition to using the above-mentioned structure, the present invention can also be combined or replaced with other filter elements, including but not limited to: textile fiber filter elements, glass fiber filter elements, stainless steel mesh filter elements, composite material filter elements, activated carbon filter elements, etc.

[0054] Optionally, the filter cartridge 2 is further provided with an oil inlet 24 , and the slag discharge port 25 and the oil inlet 24 are located at the bottom of the filter cartridge 2 .

[0055] In this embodiment, the oil inlet and the residue discharge port are arranged at the bottom of the filter cartridge, so that gravity can be used to assist and naturally promote the flow of oil and residue, thereby simplifying the structure and reducing energy consumption, thereby improving the efficiency of filtering and residue discharge.

[0056] Preferably, the oil inlet and the residue discharge port can be arranged on the top and the side of the filter cartridge, and a forced circulation system can be adopted to optimize the flow of oil and residue. The oil inlet and the residue discharge port can be arranged on the top and the side of the filter cartridge to control the inlet and outlet of oil by an external pump, thereby increasing the adaptability of the system to different working conditions.

[0057] Preferably, the top and side ports can be equipped with automatic closing valves to cope with emergencies and ensure system safety.

[0058] Optionally, a third fixing member 21 is further provided in the filter cartridge 2 , and the third fixing member 21 is used to further strengthen the connection between the filter element 3 and the filter cartridge 2 .

[0059] The third fixing member 22 in this embodiment is a locking bolt.

[0060] The third fixing member of this embodiment enhances the stability of the filter element and ensures that it maintains the correct position inside the filter cartridge, thereby improving the filtering efficiency and reliability of the equipment.

[0061] Preferably, a modular fixing system is used, which allows for quick replacement and adjustment of the filter element position;

[0062] Specifically, the modular fixing system can be designed as an adjustable clamping device or snap-on mechanism, which not only simplifies the maintenance process, but also allows the fixing position of the filter element to be adjusted according to different filtering requirements, thereby increasing the flexibility and adaptability of the equipment.

[0063] Optionally, a second fixing member 11 is further provided on the oil filter main body 1 , and the filter cartridge 2 is connected to the oil filter main body 1 via the second fixing member 11 .

[0064] The second fixing member 11 is a clamp.

[0065] This embodiment uses a clamp as the second fixing member to quickly and firmly fix the filter cartridge to the oil filter machine body, which is convenient for installation and maintenance, while ensuring the reliability and sealing of the connection.

[0066] Preferably, a fixing system of bolts and nuts can be used instead of clamps. Using a fixing system of bolts and nuts instead of clamps can provide higher load-bearing capacity and structural stability, and is particularly suitable for working environments subject to greater vibration and pressure. At the same time, bolt fixing also facilitates adjustment of the tightness to adapt to different installation and operating conditions, thereby improving the overall durability and performance of the equipment.

[0067] Optionally, the number of the filter elements 3 and the number of the filter cartridges 2 are both two.

[0068] This embodiment improves the processing capacity and redundancy of the system by equipping two filter elements and two filter cartridges, ensuring higher filtering efficiency and reliability during continuous operation.

[0069] Preferably, a single large-capacity filter cartridge with a multi-layer filter element design can be considered. The single large-capacity filter cartridge with a multi-layer filter element design can simplify the equipment structure and reduce maintenance costs while maintaining the same filtration area.

[0070] Optionally, the filter cartridge 2 is further provided with a top cover 23 , and an outer surface of the top cover 23 is provided with an oil outlet 231 communicating with the interior of the top cover 23 , and the top cover 23 is detachably connected to the filter cartridge 2 .

[0071] In this embodiment, the design of the top cover enables the oil outlet to be connected with the inside of the top cover, which facilitates the outflow of oil. Secondly, the detachable connection between the top cover and the filter cartridge facilitates cleaning and replacement of the filter element, thereby improving maintenance efficiency and equipment reliability.

[0072] Preferably, an integrated top cover can be used, wherein the top cover and the filter cartridge are connected by welding or a permanent fixing method. The top cover and the filter cartridge are connected by welding or a permanent fixing method to increase the overall strength and pressure resistance of the structure. In addition, a plurality of small oil outlets can be arranged at different positions of the top cover to optimize the flow of oil and improve the filtering efficiency.

[0073] Optionally, both the oil inlet 24 and the slag discharge port 25 are provided with a one-way valve 26 , and the one-way valve 26 is provided with a pipeline 27 , and the oil inlet 24 and the slag discharge port 25 are connected to a three-way valve 28 through the pipeline 27 .

[0074] In this embodiment, the one-way valves respectively configured on the oil inlet and the slag discharge port ensure the flow direction control of the oil and waste slag, prevent backflow, and improve the safety and efficiency of the system. At the same time, the connection with the three-way valve through the pipeline further increases the flexibility of operation and allows the oil flow direction to be quickly adjusted.

[0075] Preferably, an independent control system can be used instead of the combination of the one-way valve and the three-way valve. The independent control system that replaces the combination of the one-way valve and the three-way valve can specifically be an electronically controlled valve, wherein each valve can be remotely controlled to achieve more precise flow regulation.

[0076] Preferably, dedicated filtering and discharge systems can be provided for the oil inlet and the slag discharge port, respectively, which not only simplifies the pipeline layout but also optimizes the efficiency of each link according to different operation requirements.

[0077] Preferably, an automatic backwashing system can be added to regularly clean the inside of the filter cartridge to ensure the cleanliness and effectiveness of the filter material.

[0078] Optionally, a flow regulating device 261 is also provided on the one-way valve 26 .

[0079] In this embodiment, the flow regulating device provided on the one-way valve allows accurate control of the flow of oil or waste residue passing through, thereby improving the adjustment flexibility and operation accuracy of the system.

[0080] Preferably, an automated control system may be used to replace a manual flow regulating device.

[0081] Specifically, the automated control system can integrate sensors and microprocessors to achieve automatic flow adjustment based on real-time data. The automated control system not only improves the accuracy and response speed of flow control, but also reduces operational complexity and human errors. It is particularly suitable for industrial applications that require high precision and high reliability. In addition, the addition of intelligent monitoring functions can remotely monitor and adjust the flow, further improving the convenience and safety of the system.

[0082] Optionally, a filtering device 241 is further provided on the oil inlet 24 for preliminary filtering treatment.

[0083] Among them, the filtering device 241 is a Y-pass filter, and can be replaced by other filters, including but not limited to: a mesh filter, a magnetic filter, an activated carbon filter, a ceramic filter, a cellulose filter, etc.

[0084] In this embodiment, a Y-type filter is used as the primary filtering device at the oil inlet, which can effectively capture larger particles and impurities, protect the main filter system from wear, and improve the overall filtering efficiency and equipment life of the system.

[0085] Preferably, a cyclone separator can be used instead of a conventional Y-type filter. The cyclone separator can efficiently remove smaller particles by utilizing centrifugal force to separate impurities, thereby reducing the burden on the filter element.

[0086] Optionally, the oil filter body 1 is also provided with an electronic control device 4 and a driving device 5, and the driving device 5 is connected to the three-way valve 28 through the pipeline 27. The electronic control device 4 is used to display the working status of the oil filter body and control the driving device 5, and the driving device 5 is used to provide force to push the oil to flow upward.

[0087] The driving device 5 is an oil pump, and can be replaced by other drives, including but not limited to: an electric motor, a hydraulic motor, a pneumatic motor, etc.

[0088] In this embodiment, the combination of the electronic control device 4 and the drive device 5 (oil pump) provides efficient automatic control for the oil filter. At the same time, the electronic control device can display the working status in real time and control the oil pump to ensure the stable upward flow of oil, optimize the operating efficiency and the response speed of the system, reduce manual intervention, and improve the reliability and performance of the overall system.

[0089] In addition, the present embodiment realizes efficient filtration of oil from bottom to top. This filtering method utilizes the power of the driving device (oil pump) to push the oil to the upper part so that it can be filtered through the filter element, thereby ensuring the uniform distribution and full contact of the oil in the entire filtration process, improving the filtration efficiency and quality. Compared with the traditional gravity oil filtration method, this bottom-up filtration method is not affected by gravity, and can achieve stable and efficient oil filtration in a wider range of industrial applications, bringing users a more reliable and durable oil filtration solution.

[0090] Preferably, you can consider replacing the traditional oil pump with a variable frequency driven electric pump. The variable frequency driven electric pump can automatically adjust the flow and pressure according to the needs of the system. The variable frequency drive provides more precise control and can automatically adjust the power output according to load changes. This can not only improve energy efficiency, but also extend the service life of the equipment.

[0091] The working principle of the utility model is roughly as follows:

[0092] When working, the oil first passes through a Y-type filter for preliminary filtration to remove larger impurities, and then flows to the pressure regulating valve to adjust to the appropriate pressure. Then, the oil passes through two precision filters configured in parallel to continue to remove finer particles and impurities, ensuring that the system is not interrupted by the maintenance or replacement of a single filter. The filtered oil is monitored by a flow meter to ensure the normal operation of the system and evaluate the filtering performance. Finally, the final output flow direction is adjusted through the regulating valve. In addition, the slag and impurities accumulated in the system are automatically discharged through the slag discharge port to maintain the cleanliness of the system.

[0093] The above is only used to illustrate the technical solution of the utility model rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
