Description

Technical Field

[0001] This utility model relates to the field of oil filter equipment, and in particular to a high-efficiency oil filter. Background Technology

[0002] A high-efficiency oil filter is a device used to filter impurities, moisture, and other contaminants from oil, thereby improving the cleanliness and quality of the oil. It typically consists of a housing, filter element, inlet and outlet pipes, and seals, and features high filtration accuracy, large oil flow capacity, large dirt holding capacity, and long service life. With the continuous development of modern industry, various mechanical equipment is evolving towards higher precision, higher speed, and higher reliability. In these devices, oil not only plays a lubricating role but also participates in multiple functions such as hydraulic transmission and cooling.

[0003] Replacing filter plates or cleaning filter elements may require disassembling multiple screws or connectors using tools, a tedious process that consumes significant time and effort. For large equipment or systems requiring frequent maintenance, specialized tools may be needed, further increasing the difficulty and cost of maintenance. Inexperienced operators may also damage other filter components during disassembly, leading to prolonged downtime, impacting production efficiency, system stability and reliability, and increasing labor costs. As impurities accumulate within the filter, the oil contamination level gradually worsens, and the accumulated impurities increase the pressure on the filter. When the pressure exceeds the filter's tolerance limit, it may cause filter element rupture, housing deformation, or leaks at seals, affecting normal equipment operation and even causing equipment failure and downtime. This severely impacts production and usage, leading to increased maintenance frequency and costs. Utility Model Content

[0004] The main purpose of this utility model is to provide a high-efficiency oil filter that can effectively solve the problems of long downtime, reduced production efficiency, reduced system stability and reliability, increased labor costs, and disruption to normal equipment operation, even causing equipment failure and downtime, which seriously affect production and use, leading to increased equipment maintenance frequency and costs.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency oil filter, comprising a support plate, a cylinder fixedly connected to the left side of the support plate, a top cover provided on the top of the cylinder, a first support ring fixedly connected to the inner top wall of the cylinder, connecting blocks fixedly connected to the top left and right sides of the first support ring, locking blocks fixedly connected to the top of each of the two connecting blocks, a fixing ring provided on the top of the first support ring, a filter plate fixedly connected inside the fixing ring, two outer shells fixedly connected to the left and right sides of the fixing ring, two slots opened inside each outer shell, and a support rod slidably connected to the front and rear sides of each outer shell.

[0006] Furthermore, four springs are fixedly connected to the other side of each of the support rods, and the other ends of every eight springs are fixedly connected to the front and rear sides of the interior of a slot. Two placement slots are provided at the bottom of each support rod.

[0007] Furthermore, the outer side of each card block corresponds to the interior of each placement slot, and the hole slot of each card block corresponds to the bottom of the support rod.

[0008] Furthermore, a second support ring is fixedly connected inside the cylinder, and a fixing block is fixedly connected to the inner side wall of the second support ring. A guide ring is fixedly connected to the other side of the four fixing blocks, and a flow guide block is fixedly connected to the top of each fixing block.

[0009] Furthermore, a filter cylinder is fixedly connected inside the guide ring, a flow guide shroud is fixedly connected to the bottom of the filter cylinder, an oil drain pipe is connected through the bottom of the flow guide shroud, the bottom end of the oil drain pipe is connected through the bottom end of the cylinder, and a first control valve is provided on the outside of the bottom end of the oil drain pipe.

[0010] Furthermore, each of the support plates is fixedly connected to a support leg at its bottom, an oil inlet pipe is connected through the top front side of the cylinder, a guide plate is fixedly connected to the bottom inner wall of the cylinder, and a waste discharge pipe is connected through the bottom right side wall of the cylinder.

[0011] Furthermore, a collection cylinder is connected through the inside of the right side of the support plate, and a pump is provided on the upper side wall of the support plate. The input end of the pump is fixedly connected to a connecting pipe, and the left end of the connecting pipe is connected to the right end of the waste discharge pipe.

[0012] Furthermore, the output end of the pump is fixedly connected to a delivery pipe, the front end of which is connected through to the rear side wall of the collection cylinder, and the bottom of the collection cylinder is connected through to a drain pipe, with a second valve provided on the outer side of the bottom end of the drain pipe.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This utility model, through its first support ring, locking block, filter plate, support rod, spring, and placement groove, solves the problems of long downtime, reduced production efficiency, compromised system stability and reliability, and increased labor costs. When the filter plate needs replacement or cleaning, pressing the support rod inside the outer casing on both sides of the fixing ring overcomes the spring force, causing the placement groove at the bottom of the support rod to disengage from the locking block at the top of the connecting block. At this point, the fixing ring and filter plate can be removed upwards. After maintenance, the fixing ring is aligned with the locking block on the first support ring and lowered. The support rod is released, the spring pushes the support rod back to its original position, and the placement groove re-locks the locking block, quickly completing the installation. This effectively reduces alignment and tightening time during installation, significantly shortens equipment downtime, and improves equipment utilization.

[0015] 2. By incorporating a baffle plate, discharge pipe, collection cylinder, pump, delivery pipe, and second valve, the system effectively addresses issues that hinder normal equipment operation, potentially causing malfunctions and shutdowns, severely impacting production and usage, and leading to increased maintenance frequency and costs. Impurities intercepted by the filter plates and cylinder gradually accumulate at the bottom of the cylinder, gathering towards the discharge pipe under the guidance of the baffle plate. When cleaning is required, the pump is activated, drawing impurities from the discharge pipe via a connecting pipe and delivering them to the collection cylinder through the delivery pipe. Impurities in the collection cylinder are then discharged through a drain pipe, with the drain operation controlled by the second valve. This effectively prevents excessive accumulation of impurities on and inside the filter element, improving equipment reliability and stability, and ensuring the system's normal operation.

[0016] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0030] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0031] like Figure 1 - Figure 6 As shown: A high-efficiency oil filter includes a support plate 1. A cylinder 2 is fixedly connected to the inside of the left side of the support plate 1, and the support plate 1 supports the bottom end of the cylinder 2. A top cover 3 is provided on the top of the cylinder 2, which allows the top of the cylinder 2 to be opened for easy disassembly and cleaning of the internal components.

[0032] A first support ring 4 is fixedly connected to the inner top wall of the cylinder 2. Connecting blocks 5 are fixedly connected to the inner left and right sides of the top of the first support ring 4. Locking blocks 6 are fixedly connected to the top of each connecting block 5. A fixing ring 7 is provided at the top of the first support ring 4. The first support ring 4 provides bottom support for the fixing ring 7, thus stably installing the fixing ring 7 inside the cylinder 2. The connecting blocks 5 and locking blocks 6 on the left and right sides of the first support ring 4 connect the devices on the left and right sides of the fixing ring 7.

[0033] A filter plate 8 is fixedly connected inside the fixed ring 7. The filter plate 8 is used to perform preliminary filtration on the oil that just enters the cylinder 2, so as to filter out larger impurities in the oil. Two outer shells 9 are fixedly connected to the inside of the left and right sides of the fixing ring 7. Two slots 11 are opened inside each outer shell 9. Support rods 10 are slidably connected to the front and rear sides of each outer shell 9. Four springs 12 are fixedly connected to the other side of each support rod 10. The other end of each set of eight springs 12 is fixedly connected to the front and rear sides inside a slot 11. Two placement slots 13 are provided at the bottom of each support rod 10. The outer side of each locking block 6 corresponds to the inside of each placement slot 13. The slot of each locking block 6 corresponds to the bottom of the support rod 10. When installing the fixing ring 7 and the filter plate 8, the fixing ring 7 is set on top of the first support ring 4. The locking blocks 6 on the left and right sides of the first support ring 4 will be inserted into the placement slots 13 opened inside the outer shell 9. When the locking blocks 6 are inserted into the placement slots 13, the top of the locking blocks 6 will first contact the bottom of the support rod 10 to push the support rod 10 to slide outward inside the outer shell 9 and the slots 11, and squeeze the springs 12.

[0034] Once the locking block 6 is fully inserted into the placement slot 13, the spring 12 will release pressure, causing the support rod 10 to spring back, so that the bottom of the support rod 10 is inserted into the hole slot of the locking block 6, thus fixing the fixing ring 7 to the top of the first support ring 4.

[0035] When cleaning and disassembling the filter plate 8, first press the support rod 10 to make it slide inside the outer casing 9 and the slot 11, and squeeze the spring 12. While pressing, the bottom of the support rod 10 will slide out of the slot of the locking block 6. After sliding out, the operator presses the outer casing 9 and pulls it upward to remove the fixing ring 7 and the filter plate 8 from the top of the first support ring 4.

[0036] like Figure 1 - Figure 8As shown, a second support ring 14 is fixedly connected inside the cylinder 2. Fixing blocks 15 are fixedly connected to the inner walls of the second support ring 14. Guide rings 16 are fixedly connected to the other side of the four fixing blocks 15. A flow guide block 17 is fixedly connected to the top of each fixing block 15. A filter cylinder 18 is fixedly connected inside the guide ring 16. The second support ring 14 fixed inside the cylinder 2 is connected to the guide ring 16 through the fixing blocks 15 on its inner wall, and is connected to the filter cylinder 18 through the guide ring 16, thereby supporting the filter cylinder 18. After the oil is initially filtered by the filter plate 8 and reaches the height of the filter cylinder 18, the oil will enter the interior of the filter cylinder 18 through the pores of the filter cylinder 18. The smaller impurities in the oil are separated through the pores of the filter cylinder 18, preventing these impurities from entering the interior of the filter cylinder 18.

[0037] The separated particles flow downward through the gap between the fixed block 15 and the guide ring 16, and are guided by the guide block 17 and the guide ring 16 to prevent impurities from remaining on the outside of the filter cartridge 18.

[0038] A flow guide shroud 19 is fixedly connected to the bottom of the filter cartridge 18. An oil drain pipe 20 is connected through the bottom of the flow guide shroud 19. The bottom end of the oil drain pipe 20 is connected through the bottom end of the cylinder 2. A first control valve 21 is provided on the outside of the bottom end of the oil drain pipe 20. After the oil enters the interior of the filter cartridge 18, the oil will fall into the interior of the flow guide shroud 19. The flow guide shroud 19 guides the oil to enter the oil drain pipe 20. The oil drain pipe 20 is connected to external pipes to discharge the filtered oil into the interior of the cylinder 2.

[0039] like Figure 1 - Figure 11 As shown, each support plate 1 has a fixed support leg 22 at its bottom, which supports the bottom of the entire device. The top front of the cylinder 2 is connected to an oil inlet pipe 23, which connects to external pipes to transport oil into the cylinder 2 for processing.

[0040] A guide plate 24 is fixedly connected to the bottom wall of the inner wall of the cylinder 2, and a discharge pipe 25 is connected through the bottom of the right side wall of the cylinder 2. The guide plate 24 is used to guide the impurities at the bottom and the oil that cannot enter the filter cylinder 18, so that the oil and impurities are discharged into the cylinder 2 through the discharge pipe 25.

[0041] A collection cylinder 26 is connected through the inside of the right side of the support plate 1. A pump 27 is installed on the upper side wall of the support plate 1. A connecting pipe 28 is fixedly connected to the input end of the pump 27. The left end of the connecting pipe 28 is connected to the right end of the discharge pipe 25. A conveying pipe 29 is fixedly connected to the output end of the pump 27. The front end of the conveying pipe 29 is connected through the rear side wall of the collection cylinder 26. A drain pipe 30 is connected through the bottom of the collection cylinder 26. A second valve 31 is installed on the outer side of the bottom end of the drain pipe 30. The pump 27 is connected to the discharge pipe 25 through the connecting pipe 28 at the input end of the pump 27. When the pump 27 is started, the suction force generated is used to extract impurities and oil from inside the cylinder 2. These impurities and oil are transported to the inside of the collection cylinder 26 through the conveying pipe 29 at the output end of the pump 27 for storage and sedimentation. The impurities inside the collection cylinder 26 will precipitate in the oil.

[0042] After sedimentation, the oil inside the collection cylinder 26 is extracted through an external pipe, and the impurities inside will enter the drain pipe 30. The impurities are then discharged from the collection cylinder 26 by opening the second valve 31.

[0043] It should be noted that this utility model is a high-efficiency oil filter. First, when the oil enters the cylinder 2 through the oil inlet pipe 23, it will flow directly downwards to the filter plate 8 under the action of gravity and the oil's own pressure. The filter plate 8 performs preliminary filtration, intercepting larger particles of impurities in the oil, such as metal shavings and dust, thus achieving preliminary filtration. The preliminarily purified oil then passes through the filter plate 8 and continues downwards.

[0044] When the filter plate 8 needs to be replaced or cleaned, press the support rod 10 inside the outer casing 9 on both sides of the retaining ring 7 to overcome the elastic force of the spring 12, causing the placement groove 13 at the bottom of the support rod 10 to disengage from the locking block 6 at the top of the connecting block 5. At this time, the retaining ring 7 and the filter plate 8 can be removed upwards. After maintenance is completed, align the retaining ring 7 with the locking block 6 on the first support ring 4 and lower it. Release the support rod 10, the spring 12 pushes the support rod 10 back to its original position, and the placement groove 13 re-locks the locking block 6, quickly completing the installation.

[0045] The initially filtered oil continues to flow downwards, passing through the second support ring 14. The guide block 17 at the top of the fixing block 15 on the inner wall of the second support ring 14 guides the oil, directing it evenly through the guide ring 16 and into the filter cylinder 18. The filter cylinder 18 performs secondary fine filtration, separating smaller impurities. The oil after secondary filtration is collected through the guide shroud 19 and then discharged through the oil drain pipe 20. The oil drain pipe 20 extends through the bottom of the cylinder 2, and the discharge speed and flow rate of the filtered oil can be adjusted by controlling the first control valve 21.

[0046] Impurities intercepted by filter plate 8 and filter cylinder 18 gradually deposit at the bottom of cylinder 2 and gather towards discharge pipe 25 under the guidance of guide plate 24. When it is necessary to clean the impurities, pump 27 is started. Pump 27 extracts the impurities in discharge pipe 25 through connecting pipe 28 and sends them into collection cylinder 26 through conveying pipe 29. Impurities in collection cylinder 26 can be discharged through drain pipe 30, and the drain operation is controlled by second valve 31.

[0047] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
