Description

Technical Field

[0001] This utility model relates to the field of filtration technology, specifically to a lubricating oil circulation filtration structure. Background Technology

[0002] The lubricating oil circulation filter structure is a core device for ensuring the cleanliness of lubricating oil in mechanical systems and extending equipment life. It removes impurities (such as metal shavings, dust, colloids, etc.) from the oil through continuous circulation filtration and is widely used in industrial equipment, engines, hydraulic systems, gearboxes and other applications that require lubrication and cleaning of oil.

[0003] However, in actual use, the lubricating oil circulation filter structure can only intercept large particles of impurities and is not sufficient to remove some fine contaminants. As a result, the cleanliness of the filtered oil cannot meet the requirements of high-precision equipment. At the same time, the impurities filtered by the lubricating oil circulation filter structure tend to accumulate on the surface of the filter screen, requiring frequent shutdowns for disassembly, cleaning, or replacement of the filter element. This not only increases maintenance costs but also affects the continuous operating efficiency of the equipment. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a lubricating oil circulation filtration structure. This structure solves the problem that, in practical use, lubricating oil circulation filtration structures can only intercept large particulate impurities, and are insufficient in removing some fine contaminants. As a result, the cleanliness of the filtered oil cannot meet the requirements of high-precision equipment. At the same time, the impurities filtered by the lubricating oil circulation filtration structure tend to accumulate on the surface of the filter screen, requiring frequent shutdowns for disassembly, cleaning, or replacement of the filter element. This not only increases maintenance costs but also affects the continuous operating efficiency of the equipment.

[0005] This utility model provides a lubricating oil circulation filtration structure, comprising: a filter cylinder, a filter assembly on the filter cylinder, the filter assembly including two ends of the filter cylinder connected to conveying pipes respectively, one end of one conveying pipe connected to a control valve, the other end of the conveying pipe connected to a circulation pump, the circulation pump and the control valve connected to an oil tank, a filter frame inside the filter cylinder, multiple filter grooves opened on the filter frame and the filter cylinder, a filter frame slidably connected to the inner wall of the filter groove, a coarse filter screen, a fine filter screen and an activated carbon screen sequentially installed inside the filter frame, and auxiliary components on the filter frame and the filter cylinder.

[0006] Optionally, the auxiliary components include a filter frame and a filter cylinder with multiple electrically operated telescopic rods. The filter cylinder has a chip discharge port. One end of each of the electrically operated telescopic rods has a cleaning scraper. One side of the cleaning scraper contacts one side of the coarse filter plate and the fine filter plate. The cleaning scraper is located inside the chip discharge port. Multiple collection slots are provided below the filter cylinder. A collection box is slidably connected inside the collection slot. One side of the collection box engages with one side of the collection slot. This is for cleaning and collecting impurities attached to the coarse and fine filter plates.

[0007] Optionally, a sealing gasket is provided at the edge of the cleaning scraper and the filter frame, and the sealing gasket contacts the inside of the chip discharge port and the filter tank in order to improve the sealing performance between the cleaning scraper, the filter frame and the chip discharge port and the filter tank.

[0008] Optionally, a cooling shroud is provided on the surface of one of the delivery pipes, and multiple semiconductor cooling fins are passed through the cooling shroud to cool the filtered and delivered lubricating oil.

[0009] Optionally, the filter frame is provided with fixing buckles on both sides, and one side of the fixing buckle is connected to one side of the filter cylinder to improve the tightness between the filter frame and the filter cylinder.

[0010] Optionally, a fixing plate is provided on the surface of the conveying pipe, and multiple fixing screws are threaded on the fixing plate to improve the stability of the conveying pipe during operation.

[0011] As can be seen from the above technical solution, the lubricating oil circulation filtration structure provided by this utility model can filter impurities of different sizes and types in the lubricating oil through the filter components set in the filter cylinder. This effectively solves the problem that it can only intercept large particles of impurities and cannot fully remove fine contaminants, thus improving the cleanliness of the filtered oil and enabling it to meet the needs of high-precision equipment. At the same time, the auxiliary components set in the filter frame and filter cylinder can periodically clean the impurities attached to the surface of the coarse and fine filter screens, avoiding the accumulation of impurities that would cause filter screen blockage. This greatly reduces the number and time of frequent downtime maintenance due to impurity accumulation, lowers maintenance costs, and improves the continuous operating efficiency of the equipment. In addition, the cooling cover and semiconductor cooling fins set in the delivery pipe can cool the filtered lubricating oil, preventing oil oxidation and deterioration caused by high temperature.

[0021] Example 1

[0022] like Figures 1-3 As shown, a lubricating oil circulation filtration structure according to an embodiment of the present invention includes: a filter cylinder 1, a container for filtering lubricating oil; a filter assembly 2 on the filter cylinder 1; the filter assembly 2 includes two ends of the filter cylinder 1 connected to conveying pipes 201 for conveying and outputting lubricating oil; one end of one conveying pipe 201 is connected to a control valve 202 for controlling the lubricating oil that needs to be filtered in the oil tank 204; and one end of the other conveying pipe 201 is connected to a circulation pump 203 for circulating and extracting lubricating oil from the oil tank 204. The circulation pump 203 and the control valve 202 are connected to each other. One end of 02 is connected to an oil tank 204 for storing lubricating oil. The filter cylinder 1 is equipped with a filter frame 205. The filter frame 205 and the filter cylinder 1 have three filter slots for installing filter frames 206. The filter frames 206 are slidably connected to the inner walls of the filter slots. The filter frames 206 are sequentially equipped with a coarse filter screen 207, a fine filter screen 208, and an activated carbon screen 209 for filtering impurities in the lubricating oil. The maintenance of the coarse filter screen 207, the fine filter screen 208, and the activated carbon screen 209 is determined according to the actual situation, so it will not be described in detail.

[0023] One of the conveying pipes 201 has a cooling cover 5 on its surface for heat preservation and to reduce the leakage of cooling gas. The cooling cover 5 is made of heat-insulating material and has four semiconductor cooling chips 6 running through it for cooling the filtered lubricating oil. The cooling end of the semiconductor cooling chip 6 is located inside the cooling cover 5, and the heating end of the semiconductor cooling chip 6 is located outside the cooling cover 5. The heating end of the semiconductor cooling chip 6 is equipped with a heat dissipation structure (not shown in the figure) in actual use. The filter frame 206 has fixing buckles 7 on both sides for fixing the filter frame 206. One side of the fixing buckle 7 is connected to one side of the filter cylinder 1. The surface of the conveying pipe 201 has a fixing plate 8 for installing the conveying pipe 201. The fixing plate 8 has two fixing screws 9 threaded on it for installation and fixing.

[0024] Example 2

[0025] like Figures 1-3 , Figure 5 As shown in the figure, according to an embodiment of the present invention, an auxiliary component 3 is provided on the filter frame 205 and the filter cylinder 1. The auxiliary component 3 includes two electric telescopic rods 301 on the filter frame 205 and the filter cylinder 1, which are used to drive the cleaning scraper 303 to clean the coarse filter screen 207 and the fine filter screen 208. The filter cylinder 1 is provided with a chip discharge port 302 for discharging cleaning impurities. One end of the electric telescopic rod 301 is provided with a cleaning scraper 303 for cleaning the impurities attached to the coarse filter screen 207 and the fine filter screen 208. The cleaning scraper 303 is a detachable structure. A sealing gasket 4 is provided at the edge of the cleaning scraper 303 and the filter frame 206 to improve the sealing performance. The sealing gasket 4 is coated with a wear-resistant coating, a corrosion-resistant coating, an anti-oxidation coating, and a high and low temperature resistant coating (not shown in the figure) during actual use.

[0026] The sealing gasket 4 contacts the inside of the chip discharge port 302 and the filter tank. One side of the cleaning scraper 303 contacts one side of the coarse filter plate 207 and the fine filter plate 208. The cleaning scraper 303 is located inside the chip discharge port 302. Two collection slots are opened below the filter cylinder 1 for installing the collection box 304. The collection box 304 is slidably connected inside the collection slot for collecting the cleaned impurities. One side of the collection box 304 is engaged with one side of the inside of the collection slot.

[0027] The electric telescopic pole 301, the semiconductor cooling chip 6, the heat dissipation structure, the circulating pump 203, and the control valve 202 are electrically connected to a controller (not shown in the figure) in actual use. The controller is a PLC (programmable logic controller) or a microcontroller. By writing a suitable control program, the electrically connected electrical components can be precisely controlled. In actual use, the above structure is electrically connected to an external power supply or a battery. The specific method used depends on the actual situation.

[0028] The electric telescopic rod 301, semiconductor cooling chip 6, cooling cover 5, heat dissipation structure, coarse filter plate 207, fine filter plate 208, activated carbon mesh plate 209, circulating pump 203, control valve 202, and conveying pipe 201 are existing technologies and will not be described in detail. The specific model and specifications need to be selected and determined according to the actual specifications of the device.

[0029] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0030] In summary, with the help of the above-mentioned technical solution of this utility model, when in use, the control valve 202 is opened, the circulation pump 203 draws the lubricating oil to be filtered from the oil tank 204, and the lubricating oil is pumped into the oil inlet end of the filter cylinder 1 through the delivery pipe 201. At the same time, the control valve 202 adjusts the output of lubricating oil from the oil tank 204 to ensure stable flow. After the lubricating oil enters the filter cylinder 1, it first flows through the coarse filter screen 207 in the filter frame 206 to intercept larger particles of impurities such as metal shavings. Then it passes through the fine filter screen 208 to further remove fine particles such as dust. Finally, it passes through the activated carbon screen 209 to adsorb soluble pollutants such as colloids and oxides, thus completing deep purification.

[0031] The purified lubricating oil flows out from the oil outlet of the filter cartridge 1 and returns to the oil tank 204 through another conveying pipe 201, forming a closed loop. The surface of the oil conveying pipe 201 is wrapped with a cooling cover 5, and a semiconductor cooling chip 6 is embedded inside. The cold end of the semiconductor cooling chip 6 cools the lubricating oil in the pipe, and the hot end dissipates heat through an external radiator (not shown in the figure) to prevent the oil temperature from getting too high.

[0032] When cleaning is required, the cleaning scraper 303 is driven downward by the electric telescopic rod 301. The cleaning scraper 303 is in close contact with the surface of the coarse filter plate 207 and the fine filter plate 208, scraping the attached impurities into the chip discharge port 302 on the side wall of the filter cylinder 1. The scraped-off impurities fall into the collection box 304 below through the chip discharge port 302. At the same time, the sealing gasket 4 set on the edge of the cleaning scraper 303 ensures that there is no lubricating oil leakage in the chip discharge port 302 during filtration. When cleaning, the collection box 304 is fixed in the collection groove at the bottom of the filter cylinder 1 by sliding snap-fit, which is convenient for regular disassembly and cleaning.

[0033] When the coarse filter plate 207, fine filter plate 208, and activated carbon plate 209 require maintenance, the filter frame 206 can be removed via the locking buckle 7, facilitating the periodic replacement and maintenance of the coarse filter plate 207, fine filter plate 208, and activated carbon plate 209. The sealing gasket 4 provided in the filter frame 206 ensures the airtightness between the filter frame 206 and the filter tank during filtration.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
