Through the rotating drum, an oil surface is formed inside the drum. The drum needs to rotate at a relatively high speed to make the lubricating oil centrifugate to the upper part of the filter element so that the upper part of the filter element can filter the lubricating oil, resulting in extremely high energy consumption of the filtration equipment. When the drum speed is low, only the middle and lower parts of the filter element are centrifugally filtered, greatly affecting the filtration efficiency.

Specific embodiments

[0037] The following describes the embodiments of the present invention with reference to the attached drawings.

[0038] Embodiment 1

[0039] As Figures 3 - 7 shown, an energy-saving filtering device that can adaptively improve the cleanliness and quality of lubricating oil includes a moving frame 1 and a cylinder body 2; four universal wheels are arranged on the lower side of the moving frame 1; the cylinder body 2 is installed on the moving frame 1; an oil inlet is arranged on the upper side of the cylinder body 2; an oil outlet is arranged on the lower side of the cylinder body 2;

[0040] It further includes a rotary drum 3, a filter paper 4, a guide ring 5, a blade 6, a heating component and a cleaning system; the rotary drum 3 is installed in the cylinder body 2; the filter paper 4 is arranged on the rotary drum 3; a number of circular through holes 3001 are evenly arranged in an array on the rotary drum 3; a number of guide rings 5 are installed on the outer side of the rotary drum 3 from top to bottom; a number of blades 6 are arranged on the inner side of the rotary drum 3; the heating component is installed in the cylinder body 2; the cleaning system is arranged in the cylinder body 2.

[0041] The blade 6 is arc-shaped and the blade 6 is close to the inner wall of the rotary drum 3. When the rotary drum 3 rotates, the stationary blade 6 rotates relatively, lifting the lubricating oil centrifuged to the lower part of the inner wall of the rotary drum 3 to the upper part of the rotary drum 3, ensuring more sufficient filtration of the lubricating oil.

[0042] The inner side of the guide ring 5 is provided with an inclined surface 5001, and the inclined surface 5001 is inclined centripetally at an angle of 45 degrees, and the lowest points of a number of inclined surfaces 5001 are located below the lowest points of adjacent circular through holes 3001; the lubricating oil is guided by the inclined surface 5001 of the guide ring 5 and is sprinkled obliquely upward onto the filter paper 4, making the filter paper 4 filter the lubricating oil more evenly and fully.

[0043] The heating component includes a hollow column 301 and a heating pipe 302; the hollow column 301 is fixedly connected to the middle part inside the cylinder body 2; the heating pipe 302 is arranged inside the hollow column 301; the bottom of the hollow column 301 is fixedly connected to a plurality of blades 6; when the drum 3 rotates centrifugally, the blades 6 rotate relatively, causing the height of the lubricating oil inside the drum 3 to rise, ensuring more thorough filtration of the lubricating oil. At the same time, the heating pipe 302 heats the lubricating oil, making the viscous lubricating oil more fluid, reducing its viscosity, and accelerating the lubricating oil filtration efficiency.

[0044] It further includes a pump 101 and an oil inlet pipe 102; the pump 101 is installed on the right side of the moving frame 1; the oil inlet pipe 102 communicating with the pump 101 can send the lubricating oil into the cylinder body 2; the pump 101 transports the lubricating oil to be filtered into the drum 3 through the oil inlet pipe 102.

[0045] It further includes a first motor 201 and an oil discharge pipe 202; the first motor 201 is installed on the lower side of the cylinder body 2; the output end of the first motor 201 is fixedly connected to the drum 3; the lower side of the cylinder body 2 is communicated with the oil discharge pipe 202 that can discharge the filtered lubricating oil.

[0046] The following is a detailed description of the lubricating oil filtration process: When the lubricating oil filtration starts, the pump 101 transports the lubricating oil to be filtered into the drum 3 through the oil inlet pipe 102, drives the drum 3 to rotate through the first motor 201, the drum 3 drives the filter paper 4 to rotate together, and filters the lubricating oil through the centrifugal force of rotation. At the same time, when the drum 3 rotates centrifugally, the stationary blades 6 rotate relative to the drum 3, centrifugally move the lubricating oil along the rotation direction to the upper part of the drum 3, the lubricating oil passes through the circular through-hole 3001 on the drum 3, and then, the lubricating oil is guided by the inclined surface 5001 on the guide ring 5 and evenly sprinkled obliquely upward onto the filter paper 4, enabling the filter paper 4 to filter the lubricating oil comprehensively, accelerating the lubricating oil filtration efficiency. At the same time, the heating pipe 302 in the hollow column 301 heats the lubricating oil, making the viscous lubricating oil more lubricated, accelerating the filtration efficiency, and discharging the filtered lubricating oil through the oil discharge pipe 202.

[0047] Embodiment 2

[0048] Based on Embodiment 1, as Figures 8 - 11As shown in the figure, the cleaning system includes an electromagnetic frame 402, clamping posts 403, a disc 405, a filter cloth 406, a scraping strip 407, an inner scraping plate 408, a sewage discharge frame 409 and a collection bin 410; an electromagnetic frame 402 is arranged on the upper side of the cylinder body 2; a number of clamping posts 403 are magnetically attracted on the electromagnetic frame 402; a disc 405 is installed at the lower part inside the drum 3; a filter cloth 406 is installed at the lower part inside the drum 3, and the filter cloth 406 is located on the lower surface of the hollow column 301. The impurities in the lubricating oil are filtered through the filter cloth 406 to improve the cleanliness of the lubricating oil; a scraping strip 407 is arranged on the disc 405; an inner scraping plate 408 is installed on the drum 3; a number of return holes 3002 are opened at the lower part of the drum 3; a sewage discharge frame 409 is arranged at the lower part of the drum 3, and the sewage discharge frame 409 is movably connected with the cylinder body 2. The rotation of the drum 3 drives the sewage discharge frame 409 to rotate together, and the metal impurities at the bottom inside the drum 3 are discharged by centrifugal force, accelerating the filtering efficiency of the lubricating oil and improving the cleanliness of the lubricating oil; a collection bin 410 is installed on the lower side of the cylinder body 2.

[0049] It further includes a driving assembly, and the driving assembly includes a first driving member 401 and a second driving member 404; the first driving member 401 is installed on the upper side of the cylinder body 2, and the first driving member 401 is a push rod; the output end of the first driving member 401 is fixedly connected with the electromagnetic frame 402; the second driving member 404 is fixedly connected to the lower part inside the hollow column 301, and the second driving member 404 is a push rod; the output end of the second driving member 404 is fixedly connected with the disc 405.

[0050] The electromagnetic frame 402 is arranged in a triangular structure to improve the stability of the electromagnetic frame 402. The electromagnetic frame 402 magnetically attracts the clamping posts 403 to move and clamp into the drum 3 and the filter paper 4, and then the electromagnetic frame 402 is powered off and moves upward to separate from the clamping posts 403, realizing the fixation of the drum 3 and the filter paper 4. Then the electromagnetic frame 402 is powered on to magnetically attract the clamping posts 403 and move upward to disengage from the drum 3 and the filter paper , realizing the separation of the drum 3 and the filter paper 4, which is convenient for the drum 3 to rotate alone to clean the inside of the filter paper 4.

[0051] The return holes 3002 are arranged obliquely downward towards the center, and the return holes 3002 are slightly below the bottom of the filter paper 4. When the metal impurities mixed with the lubricating oil flow to the bottom between the drum 3 and the filter paper 4, the metal impurities mixed with the lubricating oil flow back into the drum 3 through the return holes 3002, preventing the metal impurities and the lubricating oil from accumulating at the bottom between the drum 3 and the filter paper 4, resulting in the inability to remove the metal impurities and affecting the filtering quality of the lubricating oil.

[0052] The sewage discharge rack 409 is composed of several square through pipes, and the sewage discharge rack 409 is located at the height of a disc 405 from the bottom of the drum 3. When the disc 405 moves downward to the bottom of the drum 3, the sewage outlet of the sewage discharge rack 409 is exactly above the disc 405, facilitating the discharge of metal impurities from the sewage discharge rack 409. When the drum 3 rotates, it drives the sewage discharge rack 409 to rotate, and the metal impurities in the drum 3 are discharged through the sewage discharge rack 409 by using the rotational centrifugal force, avoiding the retention of metal impurities in the drum 3, which may lead to slow lubricating oil filtration efficiency and affect the filtration efficiency.

[0053] The cleaning process is described in detail below: The first driving member 401 drives the electromagnetic rack 402 to move upward. The electromagnetic rack 402 is electrified to magnetically attract the clamping column 403, and the electromagnetic rack 402 drives the clamping column 403 to move upward until the clamping column 403 is separated from the drum 3. At this time, the drum 3 is separated from the filter paper 4. The first motor 201 drives the drum 3 to rotate, and the filter paper 4 remains stationary. The inner scraper 408 on the drum 3 cleans the inner side of the filter paper 4, scraping off the metal impurities attached to the inner side of the filter paper 4. At this time, the second driving member 404 drives the disc 405 to move downward until the return hole 3002 is exposed. The metal impurities mixed with the lubricating oil flow into the drum 3 along the return hole 3002. Then the second driving member 404 drives the disc 405 to move upward to lift the metal impurities and the lubricating oil to the lower surface of the filter cloth 406. When the disc 405 moves to contact the lower surface of the filter cloth 406, the lubricating oil passes through the filter cloth 406, while the metal impurities remain on the lower surface of the filter cloth 406. Then the first motor 201 stops driving the drum 3 to rotate. The first driving member 401 drives the electromagnetic rack 402 to move downward. The clamping column 403 magnetically attracted by the electromagnetic rack 402 is inserted into the drum 3 and the filter paper 4 to fix the drum 3 and the filter paper 4. The electromagnetic rack 402 is powered off and moves upward to separate from the clamping column 403. The first motor 201 drives the drum 3 to rotate, driving the filter paper 4 to rotate together, and the lubricating oil filtered from the filter cloth 406 is re-filtered and thrown out. At the same time, the scraping bar 407 fixed on the disc 405 rotates relative to the drum 3, scraping off the metal impurities attached to the lower surface of the filter cloth 406. At the same time, the second driving member 404 drives the disc 405 to move downward to the bottom of the drum 3. At this time, the sewage discharge rack 409 is exposed, and the metal impurities are centrifugally rotated and thrown out through the sewage discharge rack 409 into the collection bin 410, realizing the cleaning of the filter paper 4 and avoiding excessive metal impurities accumulating on the filter paper 4, which may lead to slow filtration, affecting the filtration efficiency and the cleanliness and quality of the filtered lubricating oil.

[0054] Embodiment 3

[0055] On the basis of Embodiment 1 or 2, such as Figure 1 、 Figure 2 、 Figure 12 、 Figure 13 and Figure 14As shown, it further includes an oil scraping system, and the oil scraping system includes a cleaning block 501; the cleaning block 501 is arranged inside the cylinder body 2.

[0056] The oil scraping system further includes a driving component; the driving component includes a second motor 502, a gear 503 and a pool ring 504; the cleaning block 501 is arranged on the outer side of the middle part of the cylinder body 2; the second motor 502 is installed on the cylinder body 2; the output end of the second motor 502 is fixedly connected with the gear 503; the pool ring 504 is arranged on the inner side of the middle part of the cylinder body 2, and the gear 503 meshes with the pool ring 504; the inner side of the pool ring 504 is fixedly connected with the cleaning block 501; when the lubricating oil filtration is completed, the second motor 502 drives the gear 503 to drive the pool ring 504 to rotate, and then the cleaning block 501 fixedly connected to the pool ring 504 rotates, so as to scrape the residual lubricating oil on the outer side of the filter paper 4, avoiding the lubricating oil staying on the filter paper 4 for a long time, causing the lubricating oil to deteriorate and adhere to the filter paper 4, and affecting the later lubricating oil filtration quality.

[0057] One end of the cleaning block 501 close to the filter paper 4 is Y-shaped, and the cleaning block 501 is made of rubber. When the cleaning block 501 rotates forward, the cleaning block 501 scrapes the lubricating oil on one side of the fold of the filter paper 4. When the cleaning block 501 rotates reversely, the cleaning block 501 scrapes the lubricating oil on the other side of the fold of the filter paper 4, ensuring that all the lubricating oil on the filter paper 4 is scraped off. At the same time, when the cleaning block 501 scrapes the lubricating oil on the filter paper 4, due to the reaction force of the filter paper 4, the cleaning block 501 undergoes a slight deformation, scraping the lubricating oil on the fold of the filter paper 4, avoiding the cleaning block 501 damaging the filter paper 4 when scraping the lubricating oil, resulting in the filter paper 4 being damaged and unable to filter the lubricating oil, and affecting the cleanliness and quality of the filtered lubricating oil.

[0058] The following is a detailed description of the oil scraping process: when the lubricating oil filtration is completed, the second motor 502 drives the gear 503 to drive the pool ring 504 to rotate, and then the cleaning block 501 fixedly connected to the pool ring 504 rotates, so as to scrape the residual lubricating oil on the outer side of the filter paper 4. After the lubricating oil on one side of the fold of the filter paper 4 is scraped off, the second motor 502 drives the gear 503 to rotate reversely, so as to scrape the lubricating oil on the other side of the fold of the filter paper 4, avoiding the lubricating oil staying on the filter paper 4 for a long time, causing the lubricating oil to deteriorate and adhere to the filter paper 4, resulting in slow later filtration efficiency and affecting the later lubricating oil filtration quality.
