Description

Technical Field

[0001] This utility model relates to the field of oil cooler technology, and in particular to an oil cooler with an anti-clogging structure. Background Technology

[0002] An oil cooler is a machine used to cool lubricating oil. It is commonly used in main oil tank coolers for waste heat power generation, engines and hydraulic systems in mining and light industry. During its operation, external circulating water enters the pipes inside the oil cooler to remove the heat from the hot lubricating oil entering the cooler, and then the cooled lubricating oil is discharged, thus achieving the cooling of the lubricating oil. This type of oil cooler has the characteristics of high cooling efficiency and strong corrosion resistance.

[0003] In traditional oil coolers, the circulating water often contains impurities. As the cooling time increases, these impurities tend to adhere to the inner walls of the pipes, causing blockages and affecting the normal operation of the oil cooler. Therefore, we propose an oil cooler with an anti-clogging structure to address these issues. Utility Model Content

[0004] In order to solve the technical problem of oil cooler clogging in the prior art, this utility model provides an oil cooler with an anti-clogging structure.

[0005] The present invention provides an oil cooler with an anti-clogging structure, which adopts the following technical solution:

[0006] An oil cooler with an anti-clogging structure includes a cylindrical body, with a first cover and a second cover mounted on both sides of the cylindrical body via flanges. A water inlet is mounted on the top of the first cover, and a filter assembly for filtering circulating water is installed on the water inlet. The cylinder also includes a water outlet at the bottom of the first cover. An inner cavity is provided inside the cylindrical body. An oil outlet communicating with the inner cavity is installed on the outer wall of one end of the cylindrical body, and an oil inlet communicating with the inner cavity is installed on the outer wall of the other end of the cylindrical body. A scraping assembly for scraping off lubricating oil adhering to the inner wall of the inner cavity is located inside the inner cavity. A heating assembly is provided on the water outlet to prevent lubricating oil from clogging the outlet.

[0007] By adopting the above technical solutions: the filter component enables the inlet water to be filtered, preventing impurities from entering the interior of the oil cooler and causing blockage; the scraping component enables the scraping of the inner wall of the oil cooler, preventing oil from sticking to the inner wall of the cooler and causing waste; and the heating component enables the oil outlet to be heated, preventing oil from solidifying at the oil outlet and affecting the normal flow of oil.

[0008] Furthermore, the filter assembly includes a filter frame and an activated carbon cylinder disposed at the bottom of the filter frame.

[0009] By adopting the above technical solution, the circulating water is filtered in two ways using a filter screen and an activated carbon cartridge, thereby improving the filtration effect of the circulating water.

[0010] Furthermore, an installation groove is provided at the top of the inlet, and an installation block is engaged inside the installation groove. A filter screen frame is installed on the inner side wall of the installation block, and an installation base is installed at the bottom of the filter screen frame. An activated carbon cylinder is screwed to the bottom of the installation base.

[0011] By adopting the above technical solution, it is easy to disassemble and clean the filter frame and activated carbon cylinder.

[0012] Furthermore, a pipe is installed inside the cavity, and the two ends of the pipe are connected to the inlet and outlet of the water, respectively.

[0013] By adopting the above technical solution, circulating water is added into the pipeline to cool the lubricating oil inside the cavity.

[0014] Furthermore, the scraping assembly includes an annular scraper blade for scraping off the lubricating oil adhering to the inner wall of the cavity and a servo motor for driving the annular scraper blade to move, wherein the outer wall of the annular scraper blade is in contact with the inner wall of the cavity.

[0015] By adopting the above technical solution, a servo motor drives an annular scraper to move, scraping off the lubricating oil adhering to the inner wall of the cavity, thus avoiding adhesion and waste.

[0016] Furthermore, the servo motor is mounted on the outer wall of the second cover end. A threaded rod is mounted on one side of the servo motor. After the threaded rod extends into the inner cavity, a connecting block is provided at its end. The connecting block is connected to the inner wall of the first cover end. A stop block is fixedly installed on the outer wall of the threaded rod near the connecting block. A movable seat is screwed onto the outer wall of the threaded rod. A movable ring is fixedly provided on the outer wall of the movable seat. The movable ring is fixedly connected to the annular scraper. A guide block is fixed at the top of the annular scraper. A guide groove is provided at the top of the inner cavity. The guide block and the guide groove are connected in cooperation.

[0017] By adopting the above technical solution: the moving direction of the annular scraper is guided by the guide block and the guide groove, so that the annular scraper can move smoothly in a straight line inside the cavity, and the maximum distance of the annular scraper is limited by the stop block to avoid hitting the vertical pipe position on one side of the pipeline.

[0018] Furthermore, the heating assembly includes a heating base and an electric heating tube disposed on the outer wall of the water outlet.

[0019] By adopting the above technical solution, the lubricating oil solidified on the inner wall of the water outlet can be melted by the heating base and electric heating tube, thus avoiding blockage of the water outlet.

[0020] Furthermore, the heating base has a groove inside, and an electric heating tube is installed inside the groove. The electric heating tube has a spiral structure that is evenly wound around the outer wall of the water outlet.

[0021] By adopting the above technical solution, the heating of the water outlet is made more uniform during heating.

[0022] In summary, the beneficial effects of this utility model are as follows:

[0023] 1. This oil cooler is equipped with a filter assembly, which includes an activated carbon cartridge and a filter screen. When circulating water enters the pipe inside the inner cavity through the inlet, the filter screen filters out impurities in the circulating water. Then, the activated carbon cartridge adsorbs the impurities in the circulating water, making the water entering the pipe cleaner and free of impurities. This prevents impurities from adhering to the inner wall of the pipe and causing subsequent blockage.

[0024] 2. By setting up a scraping assembly, which includes an annular scraper blade for scraping off the lubricating oil adhering to the inner wall of the cavity and a servo motor for driving the annular scraper blade to move, the inner wall of the water cooler will accumulate a certain amount of oil as the usage time increases. Through the coordinated operation of the above components, the annular scraper blade moves within a certain range on the inner wall of the cavity to scrape the inner wall of the cavity, causing the oil adhering to the inner wall of the cavity to fall off and be discharged through the oil outlet, thus avoiding accumulation and waste.

[0025] 3. By installing a heating element on the oil outlet, the cooled oil will be discharged through the water outlet. However, the cooled oil is prone to sticking to the inner wall of the water outlet, affecting the oil intake size and the smooth flow of oil. The oil outlet is heated by the electric heating tube in the heating element, which melts the oil sticking to the inner wall of the water outlet and keeps the water outlet unobstructed.

[0026] In summary, this utility model not only achieves the function of inlet filtration, preventing impurities from entering the interior of the oil cooler and causing blockage, but also achieves scraping of the inner wall of the oil cooler, preventing oil from sticking to the inner wall of the cooler and causing waste. Furthermore, it achieves the function of heating the oil outlet, preventing oil from solidifying at the oil outlet and affecting the normal flow of oil. Attached Figure Description

[0032] The present invention will be further described below with reference to specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention, but are not intended to limit the present invention.

[0033] Example 1: Please refer to Figures 1-4 As shown, an oil cooler with an anti-clogging structure includes a cylindrical body 1. A first cover 4 and a second cover 7 are respectively installed on both sides of the cylindrical body 1 via flanges 6. A water inlet 5 is installed at the top of the first cover 4, and a filter assembly for filtering circulating water is provided on the water inlet 5. Preferably, the filter assembly includes a filter screen frame 19 and an activated carbon cylinder 15 disposed at the bottom of the filter screen frame 19. An installation groove 18 is provided at the top inside the water inlet 5, and an installation block 17 is engaged inside the installation groove 18. The filter screen frame 19 is installed on the inner side wall of the installation block 17, and an installation seat 16 is installed at the bottom of the filter screen frame 19. The activated carbon cylinder 15 is installed at the bottom of the installation seat 16. The circulating water is subjected to dual filtration through the filter screen frame 19 and the activated carbon cylinder 15, thereby improving the filtration effect of the circulating water.

[0034] It also includes a water outlet 3 located at the bottom of the first cover 4. The cylinder 1 has an inner cavity 11. An oil outlet 2 communicating with the inner cavity 11 is installed on the outer wall of one end of the cylinder 1, and an oil inlet 9 communicating with the inner cavity 11 is installed on the outer wall of the other end of the cylinder 1. A pipe 14 is installed inside the inner cavity 11, and the two ends of the pipe 14 are respectively connected to the water inlet 5 and the water outlet 3. The lubricating oil in the inner cavity 11 is cooled by adding circulating water into the pipe 14.

[0035] Specifically, refer to Figure 2As shown, two sets of mounting blocks 17 are provided, and the two sets of mounting blocks 17 form a snap-fit ​​structure with the mounting groove 18. The snap-fit ​​structure design facilitates the disassembly and maintenance of the filter screen frame 19. The inner wall of the mounting base 16 is provided with external threads, and the mounting base 16 forms a threaded connection with the activated carbon cylinder 15. This structural design facilitates the disassembly and maintenance of the activated carbon cylinder 15. The pipe 14 has a serpentine design, and the pipe 14 is evenly arranged inside the inner cavity 11, so that the cooling of the lubricating oil by the pipe 14 is more uniform.

[0036] In use, after impurities in the circulating water are filtered out by the filter screen 19, the circulating water can also be purified and adsorbed by the activated carbon cylinder 15, making the circulating water cleaner before entering the interior of the pipe 14. Then, pull the filter screen 19 upward to move the mounting block 17 out of the mounting groove 18, so that the filter screen 19 can be taken out for cleaning. Then rotate the activated carbon cylinder 15 to separate it from the mounting base 16, so that the filter screen 19 and the activated carbon cylinder 15 can be separated for cleaning.

[0037] Example 2: Refer to Figure 1 and Figure 4 As shown, a scraping assembly for scraping off lubricating oil adhering to the inner wall of the inner cavity 11 is provided inside the inner cavity 11. The scraping assembly includes an annular scraper blade 24 for scraping off the lubricating oil adhering to the inner wall of the inner cavity 11 and a servo motor 8 for driving the annular scraper blade 24 to move. The outer wall of the annular scraper blade 24 is in contact with the inner wall of the inner cavity 11. Preferably, the servo motor 8 is mounted on the outer wall of the end of the second cover 7. A threaded rod 13 is mounted on one side of the servo motor 8. After the threaded rod 13 extends into the inner cavity 11, a connecting block 20 is provided at its end. The connecting block 20 is connected to the inner wall of the end of the first cover 4. A stop block 12 is fixedly installed on the outer wall of the threaded rod 13 near the connecting block 20. The stop block 12 limits the maximum distance that the annular scraper 24 can move. A movable seat 25 is screwed onto the outer wall of the threaded rod 13. A movable ring 10 is fixedly provided on the outer wall of the movable seat 25. The movable ring 10 is fixedly connected to the annular scraper 24. A guide block is fixed at the top of the annular scraper 24. A guide groove is provided at the top of the inner cavity 11. The guide block and the guide groove are connected to guide the movement of the annular scraper 24, so that the annular scraper 24 can move smoothly in a straight line inside the inner cavity 11.

[0038] When in use, the servo motor 8 is started to drive the threaded rod 13 to rotate. The threaded rod 13 drives the guide block to slide in the guide groove, so that the moving seat 25 drives the annular scraper 24 to scrape against the inner wall of the inner cavity 11, scraping off the lubricating oil adhering to the inner wall of the inner cavity 11 and discharging it through the oil outlet 2. The stop block 12 is used to limit the movement range of the annular scraper 24 to prevent it from hitting the vertical pipe position on one side of the pipe 14.

[0039] Example 3: As Figure 4 As shown, the outlet 3 is equipped with a heating component to prevent the lubricating oil inside the outlet 3 from clogging. The heating component includes a heating base 21 and an electric heating tube 22 disposed on the outer wall of the outlet 3. The heating base 21 has a groove 23 inside, and the electric heating tube 22 is installed inside the groove 23. The electric heating tube 22 has a spiral structure that is evenly wound on the outer wall of the outlet 3, so that the heating of the outlet 3 is more uniform during heating.

[0040] When in use, the electric heating tube 22 in the inner tank 23 of the heating seat 21 is activated to heat the water outlet 3, which can melt the lubricating oil solidified on the inner wall of the water outlet 3 and prevent the water outlet 3 from being blocked.

[0041] Working Principle: In use, the lubricating oil requiring cooling enters the inner cavity 11 of the cylinder 1 through the oil inlet 9. The circulating water for cooling enters the pipe 14 through the water inlet 5, carrying away the heat from the lubricating oil before exiting through the water outlet 3. As the circulating water enters the pipe 14 through the water inlet 5, the filter screen 19 inside the water inlet 5 filters out impurities. The water then passes through the activated carbon cylinder 15 for further adsorption and purification, allowing the clean circulating water to enter the pipe 14 and cool the lubricating oil. After cooling... The lubricating oil is discharged through the outlet 3. After the lubricating oil is discharged, the servo motor 8 is started to drive the threaded rod 13 to rotate. The rotation of the threaded rod 13 drives the annular scraper 24 to move from one side of the inner wall of the inner cavity 11 to the other side under the guidance of the guide block and the guide groove. This scrapes off the lubricating oil adhering to the inner wall of the inner cavity 11 to avoid adhesion and waste. When the amount of cooled lubricating oil flowing through the oil outlet 2 increases with the increase of the usage time, causing adhesion, the electric heating tube 22 can be started to heat the outlet 3, so that the lubricating oil solidified on the inner wall of the outlet 3 melts and keeps the outlet 3 unobstructed.

[0042] This oil cooler incorporates a filtration assembly, which includes an activated carbon cartridge 15 and a filter screen 19. When circulating water enters the pipe 14 inside the inner cavity 11 through the inlet 5, the filter screen 19 filters out impurities in the circulating water. Then, the activated carbon cartridge 19 adsorbs the impurities in the circulating water, making the water entering the pipe cleaner and free of impurities. This prevents impurities from adhering to the inner wall of the pipe 14 and causing subsequent blockages.

[0043] By setting up a scraping assembly, which includes an annular scraper 24 for scraping off the lubricating oil adhering to the inner wall of the inner cavity 11 and a servo motor 8 for driving the annular scraper 24 to move, the inner wall of the water cooler will accumulate a certain amount of oil as the usage time increases. Through the cooperation of the above components, the annular scraper 24 moves within a certain range of the inner wall of the inner cavity 11 to scrape the inner wall of the inner cavity 11, allowing the oil adhering to the inner wall of the inner cavity 11 to fall off and be discharged through the oil outlet 2, thus avoiding adhesion and waste.

[0044] By installing a heating element on the oil outlet 2, the cooled oil body will be discharged through the water outlet 3. However, the cooled oil body is prone to sticking to the inner wall of the water outlet 3, affecting the oil inlet size and the smooth flow of the oil body. The oil outlet 2 is heated by the electric heating tube 22 in the heating element, so that the oil body sticking to the inner wall of the water outlet 3 melts and keeps the water outlet 3 unobstructed.

[0045] This invention not only achieves the function of filtering water at the inlet to prevent impurities from entering the interior of the oil cooler and causing blockage, but also scrapes the inner wall of the oil cooler to prevent oil from sticking to the inner wall of the cooler and causing waste. In addition, it enables the oil outlet to have a heating function to prevent oil from solidifying at the oil outlet and affecting the normal flow of oil.

[0046] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. The various components mentioned in this utility model are common technologies in the existing field. 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.
