Description

Technical Field

[0001] This utility model relates to the field of filtration technology, and more specifically, to a vacuum oil collecting tower with a filtration structure. Background Technology

[0002] In existing vacuum oil collection tower technology, the filtration structure, as the core component of oil purification, plays an important role in removing solid impurities, colloidal substances and other contaminants from the oil. However, in actual operation, the timeliness of the discharge of filtered oil affects the equipment performance and operational stability.

[0003] After the filtration system completes the oil purification process, if the cleaned oil cannot be discharged from the filter structure and enter the next process step in time, oil accumulation will occur in the filter chamber and related pipelines. This will cause the internal pressure of the system to gradually increase and exceed the design operating range. This abnormal state of excessive pressure will not only cause mechanical stress damage to the filter structure itself, but may also lead to malfunctions such as filter media breakage, seal failure, and leakage at connection points, directly affecting the filtration effect and equipment lifespan. At the same time, excessive system pressure will also affect the normal operation of the vacuum pump, reduce the efficiency and stability of vacuum establishment, and thus affect the working performance of the entire oil collection tower. Secondly, excessive pressure may also cause a series of chain problems such as oil backflow, decreased filtration accuracy, increased energy consumption, and safety risks, which not only affect the quality and efficiency of oil processing, but also increase equipment maintenance costs and operational risks. Utility Model Content

[0004] (a) Technical problems to be solved In view of the problems existing in the prior art, this utility model provides a vacuum oil collecting tower with a filtration structure to solve the technical problems mentioned in the background art.

[0005] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a vacuum oil collecting tower with a filtration structure, comprising a support frame, wherein two sets of support frames are provided, and filter barrels are provided on the support frames, with an oil inlet pipe and an oil outlet pipe connecting the two sets of filter barrels; it also includes a pressure relief mechanism, wherein the pressure relief mechanism includes a pressure relief pipe, the pressure relief pipe is fixedly connected to the lower end face of the filter barrel, and a threaded pipe is threadedly connected to the bottom of the pressure relief pipe, and multiple sets of oil discharge holes are opened on the surface of the threaded pipe.

[0006] Preferably, the filter barrel is equipped with a filter screen inside, which enables the effective interception and separation of solid particles, colloidal substances and other impurities in the original oil.

[0007] Preferably, the pressure relief pipe is provided with a limiting sleeve, and a sampling tube is slidably connected inside the limiting sleeve. The sampling tube is provided with multiple sets of limiting plates. The setting of multiple sets of limiting plates ensures the precise positioning and smooth movement of the push rod inside the sampling tube, effectively preventing deviation and jamming during sampling operations, and improving the accuracy and reliability of sampling operations.

[0008] Preferably, a push rod is slidably connected inside the sampling tube. The push rod is slidably connected between multiple sets of limiting plates. One end of the push rod is provided with a sealing block, the diameter of which is the same as the inner wall diameter of the sampling tube. The other end of the push rod is connected to a push plate, and the upper surface of the push plate is provided with a compression spring. The other end of the compression spring is fixedly connected to the outer surface of the sampling tube. The sliding connection between the push rod and the limiting plate realizes precise control and smooth execution of the sampling action. The perfect match between the sealing block and the inner wall of the sampling tube ensures reliable sealing and leakage prevention of the sampling channel. The elastic restoring force of the compression spring provides the push rod system with an automatic reset function and continuous sealing pressure, making the sampling operation simple and quick and the sealing effect durable and reliable.

[0009] Preferably, the inner wall of the pressure relief pipe is provided with a partition, the lower end face of the partition is provided with a sealing groove, the outer wall of the push rod is slidably connected with a sealing disc, the sealing disc is located below the partition and is adapted to the sealing groove, the lower end face of the limiting sleeve is provided with a tension spring, the other end of the tension spring is connected to the upper end face of the sealing disc, and the adaptation design of the sealing disc and the sealing groove ensures that the pressure relief channel is completely closed under normal conditions and accurately opened when the pressure is abnormal.

[0010] Preferably, the threaded tube is provided with a push spring, the other end of which is connected to the lower end face of the sealing disc. The upward pushing force of the push spring and the upward pulling force of the tension spring form a dual elastic support mechanism, providing the sealing disc with a more stable balance and adjustable starting pressure.

[0011] Preferably, the pressure relief pipe has an oil outlet on its side wall, and the oil outlet corresponds to the oil drain hole on the surface of the threaded pipe. The corresponding arrangement of the oil outlet and the oil drain hole ensures that the cleaning oil can be discharged smoothly under any adjustment state, avoiding the flow channel blockage problem that may be caused during the movement of the threaded pipe.

[0012] (III) Beneficial Effects Compared with the prior art, this utility model provides a vacuum oil collecting tower with a filtration structure, which has the following advantages: This vacuum oil collecting tower with a filtration structure solves the problem of excessive pressure caused by untimely discharge of filtered oil in traditional oil collecting towers through the organic integration of a pressure relief mechanism and a sampling and detection system.

[0013] This device employs a precise fit design between the sealing disc and the sealing groove. Through a bidirectional elastic balance mechanism of push and pull springs, it ensures reliable sealing of the pressure relief system under normal operating conditions and automatic activation in case of abnormal pressure. When the pressure inside the filter tank exceeds the set threshold, the sealing disc automatically overcomes spring resistance, moves downward, and releases the seal, allowing the cleaning oil to be discharged promptly through the pressure relief channel. This effectively prevents damage to the filter structure and vacuum system caused by system pressure overload. The adjustable design of the threaded pipe, combined with the arrangement of multiple sets of oil drain holes on the surface, not only allows for adjustment of the pressure relief start-up pressure but also ensures unobstructed flow of the cleaning oil during adjustment, avoiding potential flow blockage problems. The built-in push rod and sealing block system in the sampling tube, driven by the elasticity of the compression spring and guided by multiple sets of limiting plates, realizes convenient operation and reliable sealing of oil sampling. The staff only needs to push the push plate to complete the quantitative sampling and quality testing of clean oil. After sampling, the system automatically resets and restores the sealing state, which not only ensures the timeliness and accuracy of oil quality monitoring, but also avoids the risk of oil leakage and contamination that may be caused by traditional sampling methods. The integrated design of the entire pressure relief mechanism and the filtration system ensures the timely discharge of filtered clean oil and stable control of system pressure, improves the operational stability, operation convenience and maintenance efficiency of the oil collection tower, and effectively extends the service life of the equipment.

[0019] Please see Figures 1 to 5 A vacuum oil collecting tower with a filtration structure includes a support frame 11, which has two sets. A filter barrel 12 is mounted on the support frame 11, and an oil inlet pipe 13 and an oil outlet pipe 14 connect the two sets of filter barrels 12. A filter screen 15 is installed inside the filter barrel 12. The tower also includes a pressure relief mechanism, which includes a pressure relief pipe 21 fixedly connected to the lower end face of the filter barrel 12. A threaded pipe 22 is threadedly connected to the bottom of the pressure relief pipe 21. Multiple sets of oil discharge holes 23 are formed on the surface of the threaded pipe 22. A limiting sleeve 24 is provided inside the pressure relief pipe 21. A sampling pipe 25 is slidably connected inside the limiting sleeve 24. Multiple sets of limiting plates 26 are provided inside the sampling pipe 25. A push rod 27 is slidably connected inside the sampling pipe 25, slidingly connected between the multiple sets of limiting plates 26. A sealing block 28 is provided at one end of the push rod 27. The diameter of the 8 is the same as the inner diameter of the sampling tube 25. The other end of the push rod 27 is connected to the push plate 29. The upper end of the push plate 29 is provided with a compression spring 210. The other end of the compression spring 210 is fixedly connected to the outer surface of the sampling tube 25. The inner side wall of the pressure relief pipe 21 is provided with a partition 211. The lower end of the partition 211 is provided with a sealing groove 212. The outer side wall of the push rod 27 is slidably connected with a sealing disc 213. The sealing disc 213 is located below the partition 211 and is adapted to the sealing groove 212. The lower end of the limiting sleeve 24 is provided with a tension spring 214. The other end of the tension spring 214 is connected to the upper end of the sealing disc 213. The threaded tube 22 is provided with a push spring 215. The other end of the push spring 215 is connected to the lower end of the sealing disc 213. The side wall of the pressure relief pipe 21 is provided with an oil outlet 216. The position of the oil outlet 216 corresponds to the position of the oil drain hole 23 opened on the surface of the threaded tube 22.

[0020] This device is installed on the oil collecting tower. Oil flows into the filter tanks 12 on both sides through the inlet pipe 13, is filtered by the filter screen 15, and flows down into the bottom of the filter tank 12. The filtered clean oil is discharged through the outlet pipe 14. When the clean oil is not discharged in time, a large pressure will be generated in the filter tank 12, requiring pressure relief. The clean oil flows into the pressure relief pipe 21. Due to excessive pressure, the sealing disc 213 moves down against the thrust of the push spring 215 and the tension of the tension spring 214, releasing the seal connection with the sealing groove 212. The clean oil flows into the bottom of the pressure relief pipe 21 through the gap between the sealing disc 213 and the partition plate 211, and then is discharged into the external oil storage tank through the outlet 216, achieving the pressure relief effect. When the sealing disc 213 and the sealing groove 212 are in a sealed state, the thrust of the push spring 215 and the tension of the tension spring 214 make the seal more stable. When it is necessary to adjust the thrust of the push spring 215 on the bottom of the sealing disc 213, the threaded pipe 22 is manually rotated. The threaded tube 22 moves up and down within the pressure relief tube 21, causing the push spring 215 to move up and down. This allows adjustment of the push force of the push spring 215 on the sealing disc 213. When the threaded tube 22 moves upward, it obstructs the discharge of the cleaning oil. At this time, the cleaning oil can be discharged through the drain hole 23 on the surface of the threaded tube 22 and then through the oil outlet 216. The design of the drain hole 23 reduces this obstruction. When it is necessary to test whether the filtered cleaning oil meets the standards, the push plate 29 can be manually pushed upward. The push plate 29 drives the push rod 27 to move upward simultaneously, compressing the compression spring 210. The push rod 27 pushes the top sealing block 28 upward, releasing the seal between the sealing block 28 and the sampling tube 25. The cleaning oil can then flow out along the sampling tube 25 to achieve sampling. After sampling, the push plate 29 is released, and the compression spring 210 rebounds, pushing the push plate 29, along with the push rod 27 and the sealing block 28, back to the initial position, thus re-sealing the sealing block 28 and the sampling tube 25.
