Description

Technical Field

[0001] This invention relates to the field of antifreeze filtration technology, specifically to an antifreeze filtration device. Background Technology

[0002] Antifreeze, or simply antifreeze, effectively prevents coolant from freezing when the car is parked in cold winter, thus avoiding radiator cracking and engine cylinder block or cover damage caused by freezing.

[0003] After prolonged use, antifreeze often accumulates a large amount of impurities. To ensure its normal operation, antifreeze usually needs to be filtered. However, conventional filtration equipment cannot automatically clean the filter screen. Therefore, after filtering for a period of time, a large amount of impurities will accumulate on the surface of the filter screen in the fluid path. These impurities gradually clog the filter screen, causing the fluid path to narrow and thus reducing the filtration effect. Summary of the Invention

The solid waste is guided into the solid impurity storage mechanism by the material guide plate, thereby preventing the waste from accumulating and clogging the filter bucket, ensuring the cleanliness of the filter bucket surface and the smooth flow of liquid.

[0017] 2. This antifreeze filtration device, through the setting of an inner connecting ring, filter funnel, filter residue holes, centrifugal motor, driving gear, driven gear ring and sealing ring, can generate driving force through the centrifugal motor to rotate the inner connecting ring and filter funnel. Utilizing the conical surface of the filter funnel and the centrifugal effect during rotation, it ensures that the solid waste residue isolated on its surface can be guided in the direction of the force axis, and the filter residue holes ensure that the coolant can pass through smoothly to achieve filtration.

[0018] 3. This antifreeze filtration device, through the setting of a liquid sealing cover, liquid guiding cover, material pushing plate, anti-slip strip and material guiding brush, can improve the pushing effect on waste residue when the liquid sealing cover rotates, and restrict the direction of waste residue by the enclosure of the liquid sealing cover and the filter hopper, so as to ensure that more waste residue can enter the centrifugal slag storage cylinder.

[0019] 4. This antifreeze filter device, through the design of a flow guide clip and clip, ensures the secure connection of the centrifugal sludge cylinder, facilitates the disassembly and installation of the centrifugal sludge cylinder, and makes it easy to clean the waste residue from the centrifugal sludge cylinder.

[0020] 5. This antifreeze filtration device, through the setting of a reflux guide cover, a support docking guide cover, a rotating ring, an anti-slip ring, and a reflux groove, can isolate and separate the outer space of the centrifugal slag cylinder from the inside of the sealing cover, so as to avoid large disturbances between the antifreeze entering the sealing cover and the antifreeze returning from the centrifugal slag cylinder.

[0021] 6. This antifreeze filtration device, through the installation of a centrifugal sludge storage cylinder, isolation net, isolation sponge, and snap-fit ​​rubber ring, can temporarily store the filtered waste residue in the centrifugal sludge storage cylinder, thereby ensuring that the waste residue will not accumulate below the filter hopper and affect the smooth flow of antifreeze.

[0022] 7. This antifreeze filtration device, through its upper support frame, connecting column, inner support frame, lower edge column, brush plate, spring plate, and cleaning brush bristles, can effectively remove the waste residue clogging the filter pores during the rotation of the filter hopper by the relative brushing motion between the cleaning brush bristles and the filter hopper, ensuring that the filter pores remain unobstructed.

By using the conical surface of the filter hopper 202 and the centrifugal effect during rotation, the solid waste residue isolated on its surface can be guided to the direction of the far axis. And through the filter residue hole 203, the coolant can pass smoothly to achieve filtration through the filter residue hole 203.

[0039] The centrifugal feeding mechanism includes a sealing cover 301, a feeding cover 302, a feeding plate 303, an anti-slip strip 304, and a feeding brush 305.

Through the arrangement of the return guide cover 401, the support docking guide cover 402, the rotating ring 403, the anti-slip ring 404 and the return groove 405, the outer space of the centrifugal slag cylinder 501 can be isolated and separated from the inside of the liquid cover 301 to a certain extent, so as to avoid large disturbances between the antifreeze entering the liquid cover 301 and the antifreeze returning from the centrifugal slag cylinder 501.

[0042] The solid impurity storage mechanism includes a centrifugal slag storage cylinder 501, an isolation net 502, an isolation sponge 503, and a snap-fit ​​rubber ring 504.

Through the upper support frame 601, connecting column 602, inner support frame 603, lower edge column 604, brush plate 605, spring plate 606 and cleaning bristles 607, the relative brushing between the cleaning bristles 607 and the filter hopper 202 during the rotation of the filter hopper 202 can effectively remove the waste residue blocking the filter residue hole 203, ensuring that the filter residue hole 203 remains unobstructed.

[0044] Among them, a liquid guiding channel is provided between the liquid sealing cover 301 and the filter hopper 202. The free end of the guiding brush 305 is inclined outward, and the surface of the guiding brush 305 is slidably connected to the lower surface of the inner ring 201. In order to realize the unidirectional waste slag channel, the outward inclined guiding brush 305 design ensures that the waste slag can smoothly enter the centrifugal slag storage cylinder 501, while preventing the waste slag from flowing back.

[0045] Working principle: During use, the equipment is installed near the automotive antifreeze storage device via an external bracket 107, connecting the middle section of the antifreeze return pipe to the inlet 104 and outlet 108. During filtration, the pump motor 106 and centrifugal motor 204 are started. The centrifugal motor 204 drives the driven gear ring 206 to rotate via the drive gear 205, which in turn drives the inner ring 201 and filter hopper 202 to rotate. Simultaneously, the pump motor 106 drives the pump fan 109 to rotate, generating thrust during rotation to transport the antifreeze upwards. The antifreeze enters the equipment from the inlet 104, then passes through the return guide cover 401 and the support docking guide cover 402, and enters the interior of the guide cover 302. Finally, the antifreeze reaches the sealing cover 301 and the filter hopper 202. During the process, some antifreeze passes through the filter slag holes 203 for filtration, continues to move upward and is finally discharged from the drain port 108, entering the antifreeze return pipe. The other part of the antifreeze and the trapped impurities remain below the filter hopper 202. Driven by the rotating feed plate 303 and guided by the lower surface of the filter hopper 202, it passes through the guide brush 305 and finally enters the centrifugal slag storage cylinder 501. Since the centrifugal slag storage cylinder 501 is also rotating, the antifreeze and waste residue subjected to centrifugal force continue to be thrown outward. The isolation net 502 and the isolation sponge 503 play the role of blocking the waste residue, which is intercepted inside the centrifugal slag storage cylinder 501. The filtered antifreeze passes through the isolation net 502 and returns to the inside of the support shell 101, and flows back down along the support shell 101. Then it passes through the return groove 405 and merges with the antifreeze that entered the equipment.
