Description

Technical Field

[0001] This invention relates to the field of liquid level gauge filter cleaning technology, specifically an automated anti-clogging liquid level gauge. Background Technology

[0002] A float level switch is a common liquid level measuring device, also known as a float level switch. It is commonly used in industrial and commercial applications to monitor the liquid level and control the operation of equipment or issue alarm signals based on the level.

[0003] Currently, when using magnetic floats to monitor liquid levels, solid impurities in the measured medium often enter the liquid level gauge along with the fluid. On the one hand, if solid impurities adhere to the magnetic float or the inner wall of the liquid level gauge tube, they can easily prevent the magnetic float from moving smoothly. Excessive adhesion can even cause blockage, affecting the accuracy of the monitoring results. Although existing technologies can solve this problem by adding a filter screen, after long-term use, solid particles can easily become embedded in the mesh of the filter screen, causing blockage. Generally, the filter screen needs to be removed for cleaning, which is not only cumbersome, but also affects the continuous monitoring of the measured medium. Summary of the Invention

[0004] The purpose of this invention is to provide an automated anti-clogging level gauge to solve the problem mentioned in the background art that when the filter screen is used for a long time, solid particles and impurities are easily embedded inside the mesh, causing blockage. Generally, the filter screen needs to be disassembled for cleaning of the filter holes, which is not only cumbersome, but also affects the continuous monitoring of the measured medium.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an automated anti-clogging level gauge, comprising a measuring cylinder, a guide tube being installed on one side of the bottom of the measuring cylinder, a filter plate being rotatably and sealingly installed inside the guide tube near the measuring cylinder, and a plurality of filter holes being circumferentially and circumferentially through the interior of the filter plate; a filter anti-clogging mechanism, the filter anti-clogging mechanism being located inside the guide tube near the filter plate, the function of the filter anti-clogging mechanism being to automatically clean and remove the clogging impurities inside the filter holes from the inside of the guide tube; and a scraping mechanism, the scraping mechanism being located outside the filter plate on the side away from the measuring cylinder, and a cleaning mechanism being provided on the inner wall of the guide tube near the scraping mechanism.

[0006] Furthermore, the filter anti-clogging mechanism includes a toothed ring, a drive motor, a limiting gear, and an isolation cover. The toothed ring is fixedly wrapped around the edge of the filter plate outside the conduit. The drive motor is fixed to one side of the bottom end of the conduit. The output end of the drive motor is fixed to the limiting gear, and one side of the limiting gear is meshed with one side of the toothed ring. An isolation cover is longitudinally fixed at the middle position of the bottom end of the conduit near the filter plate and away from the measuring cylinder. One side of the opening end of the isolation cover is attached to the outside of the bottom end of the filter plate.

[0007] Furthermore, the filter anti-clogging mechanism also includes a limiting telescopic rod, a clearing head, a compression spring, and a sector-shaped sealing plate. The limiting telescopic rods are fixed at equal intervals on the inner wall of the isolation cover near the filter plate. The limiting telescopic rods are all sleeved and connected to the outside of each limiting telescopic rod. The clearing head is fixed to the end of each limiting telescopic rod near the filter plate. A sector-shaped sealing plate is fixed through one side of the isolation cover, and one side of the sector-shaped sealing plate is in contact with and sealed to one side of the outer surface of the filter plate.

[0008] Furthermore, the filter anti-clogging mechanism also includes a second isolation cover, a second fan-shaped sealing plate, and a roller. The second isolation cover is longitudinally attached to the bottom side of the filter plate away from the first isolation cover, and the second isolation cover is symmetrically arranged with the first isolation cover. The second fan-shaped sealing plate is fixedly attached to one side of the second isolation cover, and one side of the second fan-shaped sealing plate is also attached and sealed to one side of the outer surface of the filter plate. The roller is symmetrically rotated and installed inside the top and bottom of the second isolation cover.

[0009] Furthermore, the filter anti-clogging mechanism also includes a worm gear, a worm, a conveyor belt, and hooks. A worm gear is fixed to the outside of one end of the bottom roller shaft of the isolation cover. A worm is coaxially fixed to the middle of one side of the limiting gear, and one side of the worm meshes with one side of the worm gear. A conveyor belt is sleeved between the two roller shafts, and several hooks are fixed at equal intervals on the outer surface of the conveyor belt.

[0010] Furthermore, the filtering and anti-clogging mechanism also includes an abutment brush plate and a collection box. An abutment brush plate is obliquely fixed on the inner wall of the isolation cover second near the bottom end of the conveyor belt, and the abutment brush plate is attached to the outside of several hooks. A collection box is installed on the outside of the bottom end of the isolation cover second.

[0011] Furthermore, the scraping mechanism includes a scraper plate, a return spring, and a limiting bevel gear. The scraper plate is rotatably and obliquely mounted on one side edge of the first sector-shaped sealing plate via a rotating seat, and one side outer surface of the scraper plate is in contact with one side outer surface of the filter plate. Several return springs are fixedly connected at equal intervals between the other side outer surface of the scraper plate and the outer side of one side of the first sector-shaped sealing plate. A limiting bevel gear is fixed at the center position of one side of the filter plate.

[0012] Furthermore, the scraping mechanism also includes an abutting roller, a bevel gear rod, and an abutting rod. The bevel gear rod is meshed with the limiting bevel gear on the side near the shovel plate. The bevel gear rod is rotatably mounted on the outside of one side of the sector-shaped sealing plate via a bracket. An abutting rod is fixed to the end of the bevel gear rod away from the limiting bevel gear. An abutting roller is rotatably mounted on the outside of one end of the shovel plate near the abutting rod via a bracket.

[0013] Furthermore, the cleaning mechanism includes a strong magnet, a limiting ring, and a sliding groove. The strong magnet is externally embedded on the edge of the filter plate near the limiting bevel gear. The limiting ring is fixed on the inner wall of the guide tube near the shovel plate. The sliding groove is internally embedded in the limiting ring.

[0014] Furthermore, the cleaning mechanism also includes a second strong magnet, ball bearings, and a scraper. The second strong magnet is slidably engaged inside one side of the chute. Several ball bearings are circumferentially embedded and rotatably mounted on the inner wall of the chute at equal angles. A scraper is fixed to the outside of the end of the second strong magnet away from the first strong magnet, and one side of the scraper is in contact with the inner wall of one side of the guide tube. The first strong magnet and the second strong magnet attract each other.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. During use, the drive motor rotates the filter plate. When it rotates to a certain angle, the filter holes on the filter plate align with the unclogging head on one side. The return of the compression spring on one side causes the unclogging head to push against the inside of the filter hole, pulling the impurities blocking the filter hole into the multiple hooks on the side, thus completing the automatic cleaning of the filter hole. At the same time, when the output shaft of the drive motor rotates, it drives the roller shaft inside the second side isolation cover to rotate synchronously, so that the conveyor belt outside the roller shaft and several hooks rotate synchronously and switch to transport the impurities hooked on the hooks to the top of the collection box. Then, the inclined brush plate scrapes the impurities hooked on the hooks into the collection box, so that the whole device can automatically clean the filter holes in the filter plate in an orderly manner and automatically discharge the impurities. The overall performance is good, no manual intervention is required, and it does not affect the continuous monitoring of the measured medium.

[0017] 2. When the filter plate rotates, as it approaches the inclined shovel, the shovel removes impurities from the filter plate surface, preventing them from adhering and clumping. This ensures the filter plate surface remains flat and clean, allowing it to enter the fan-shaped sealing plate smoothly without any clumping of impurities on the filter plate surface coming into contact with and causing wear on the fan-shaped sealing plate, thus affecting its sealing effect. Simultaneously, the rotation of the filter plate drives the limiting bevel gear and bevel gear rod to rotate and engage with the rollers, causing the shovel to descend. When the engagement rod disengages from the engagement rollers, it rebounds with the help of a return spring, allowing the shovel to reciprocate, rotating downwards and rebounding. This vibrates and removes some of the impurities removed from the shovel's surface, achieving an automatic cleaning effect. Overall, the filter plate performs well.

[0018] 3. Through the corresponding attraction between strong magnet one and strong magnet two, and the installation and cooperation of the limiting ring and the sliding groove, the filter plate will drive strong magnet two and the side scraper to stick to the inner wall of the tube when rotating, and rotate and scrape to clean the inner wall of the tube, so as to avoid the impurities from clumping together and affecting the inner diameter of the tube, causing the liquid to flow poorly.

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] Please see Figure 1-12 This invention provides a technical solution: an automated anti-clogging level gauge, comprising a measuring cylinder 1, a guide tube 2 installed on one side of the bottom of the measuring cylinder 1, a filter plate 3 rotatably and sealingly installed inside the guide tube 2 near the measuring cylinder 1, and a plurality of filter holes 4 circumferentially and through the interior of the filter plate 3; a filter anti-clogging mechanism 5, located inside the guide tube 2 near the filter plate 3, the function of which is to automatically clean and remove the blockage impurities inside the filter holes 4 from the inside of the guide tube 2; and a scraping mechanism 6, located outside the filter plate 3 on the side away from the measuring cylinder 1, and a cleaning mechanism 7 provided on the inner wall of the guide tube 2 near the scraping mechanism 6.

[0034] In this embodiment, the automated anti-clogging level gauge mainly includes a measuring cylinder 1, a conduit 2, a filter anti-clogging mechanism 5, a scraping mechanism 6, and a cleaning mechanism 7. In actual use, the automated anti-clogging level gauge provided by this solution first fixes the conduit 2 to the side of the storage tank. Subsequently, the liquid enters the measuring cylinder 1 through the conduit 2. A floating magnetic float is installed inside the measuring cylinder 1. The magnetic float, together with the flip-plate indicator block, monitors the liquid level of the monitored medium. The specific principle of the magnetic flip-plate liquid level monitoring is existing technology and will not be described in detail here.

[0035] When the medium passes through the filter plate 3 in the filter structure, the filter plate 3 and filter holes 4 can filter out impurities mixed in the medium, playing a role in removing impurities from the medium entering the measuring cylinder 1, and preventing impurities from affecting the normal operation of the liquid level monitoring device. During use, the filter anti-clogging mechanism 5 is activated simultaneously. Through the operation of the filter anti-clogging mechanism 5, the filter holes 4 in the filter plate 3 can be automatically cleaned in an orderly manner and impurities can be automatically discharged. The overall use effect is good, no manual intervention is required, and it will not affect the continuous monitoring of the measured medium. During the operation of the filter anti-clogging mechanism 5, the scraping mechanism 6 and the cleaning mechanism 7 will be activated simultaneously. Through the operation of the scraping mechanism 6, the impurities attached to the surface of the filter plate 3 are scraped and cleaned to ensure the flatness and cleanliness of the surface of the filter plate 3. Through the operation of the cleaning mechanism 7, the inner wall of the conduit 2 is automatically rotated and scraped to clean, preventing impurities from accumulating and affecting the inner diameter of the conduit 2, thus preventing the liquid flow from being obstructed.

[0036] In some embodiments, the filter anti-clogging mechanism 5 includes a toothed ring 501, a drive motor 502, a limiting gear 503, and an isolation cover 504. The toothed ring 501 is fixedly wrapped around the edge of the filter plate 3 outside the conduit 2. The drive motor 502 is fixed to one side of the bottom end of the conduit 2. The limiting gear 503 is fixed to the output end of the drive motor 502, and one side of the limiting gear 503 is meshed with one side of the toothed ring 501. An isolation cover 504 is longitudinally fixed at the middle position of the side of the conduit 2 near the bottom end of the filter plate 3 away from the measuring cylinder 1. The open end of the isolation cover 504 is attached to the outside of the bottom end of the filter plate 3. The filter anti-clogging mechanism 5 also includes a limiting telescopic rod 505, a clearing head 506, a compression spring 507, and a sector-shaped sealing plate 508. The limiting telescopic rods 505 (e.g., 505) are fixed at equal intervals on the inner wall of the isolation cover 504 near the filter plate 3. Figure 5 As shown), compression springs 507 are sleeved and connected to the outside of the limiting telescopic rod 505. A cleaning head 506 is fixed to the end of the limiting telescopic rod 505 near the filter plate 3. A fan-shaped sealing plate 508 (as shown) is fixed through one side of the isolation cover 504. Figure 8 As shown), one side of the fan-shaped sealing plate 508 is in contact with and sealed to one side of the outer surface of the filter plate 3.

[0037] Combination Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, during use, the drive motor 502 starts and drives the limit gear 503 to rotate. The limit gear 503 meshes with one side of the gear ring 501, thereby driving the filter plate 3 to rotate. When the filter plate 3 rotates to a certain angle, a set of filter holes 4 on the filter plate 3 aligns with several unclogging heads 506 on one side. At this time, the unclogging heads 506 are no longer resisted by the flat surface of the filter plate 3, causing the compression spring 507 on one side to quickly rebound and drive the unclogging heads 506 to push into the filter holes 4, pushing out the impurities blocking the filter holes 4 and cleaning them, thus completing the automatic contact cleaning of the filter holes 4.

[0038] In some embodiments, the filter anti-clogging mechanism 5 further includes a second isolation cover 509, a second sector-shaped sealing plate 5010, and a roller 5011. The second isolation cover 509 is longitudinally and fitted onto the bottom end of the filter plate 3 away from the first isolation cover 504, and the second isolation cover 509 is symmetrically arranged with the first isolation cover 504. The second sector-shaped sealing plate 5010 is fixedly fixed to one side of the second isolation cover 509, and one side of the second sector-shaped sealing plate 5010 is also fitted and sealed to one side of the outer surface of the filter plate 3. The roller 5011 is symmetrically and rotatably installed inside the top and bottom ends of the second isolation cover 509. The filter anti-clogging mechanism 5 also includes a worm gear 5012, a worm 5013, and a conveyor. The filter anti-clogging mechanism 5 also includes a belt 5014 and hooks 5015. A worm gear 5012 is fixed externally to one end of the bottom roller 5011 of the second isolation cover 509. A worm 5013 is coaxially fixed to the middle of one side of the limiting gear 503, and one side of the worm 5013 meshes with one side of the worm gear 5012. A conveyor belt 5014 is sleeved between the two rollers 5011, and several hooks 5015 are fixed at equal intervals on the outer surface of the conveyor belt 5014. The filter anti-clogging mechanism 5 also includes a contact brush 5016 and a collection box 5017. The contact brush 5016 (e.g., a collection box 5017) is obliquely fixed to the inner wall of the second isolation cover 509 near the bottom of the conveyor belt 5014. Figure 7 As shown), the abutment brush plate 5016 is attached to the outside of several hooks 5015, and the bottom of the isolation cover 2 509 is externally connected to a collection box 5017.

[0039] Combination Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, when the unclogging head 506 engages to remove blockages, it pushes out the impurities blocking the filter hole 4 and engages them with multiple hooks 5015 on the side. The hooks 5015 hook and limit the discharged impurities, ensuring that the unclogging head 506 will not carry impurities back into the filter hole 4 when it resets. At the same time, when the output shaft of the drive motor 502 drives the limit gear 503 to rotate, it will drive the side worm gear 5013 to rotate synchronously. The rotation of the worm gear 5013 will drive the meshing worm wheel 5012 on one side to rotate synchronously, thereby driving the roller shaft 5011 inside the isolation cover 2 509 to rotate synchronously. The roller 5011 rotates, causing the conveyor belt 5014 and several hooks 5015 outside the roller 5011 to rotate synchronously and switch between conveying and transporting. This rotates the impurities hooked on the hooks 5015 to the top of the collection box 5017. Then, the inclined abutment brush plate 5016 scrapes the impurities hooked on the hooks 5015 into the collection box 5017. This allows the device to automatically and orderly clean the filter holes 4 in the filter plate 3 and automatically discharge the impurities. The overall performance is good, no manual intervention is required, and it does not affect the continuous monitoring of the measured medium.

[0040] Simultaneously combined Figure 8 As shown, the symmetrical arrangement of sector-shaped sealing plate 508 and sector-shaped sealing plate 5010 ensures that when half of the filter hole 4 is between sector-shaped sealing plate 508 and sector-shaped sealing plate 5010, the liquid will not enter the interior of the isolation cover 509 as it passes through the filter hole 4. This is because the liquid is blocked by sector-shaped sealing plate 508 and sector-shaped sealing plate 5010, thus ensuring overall sealing and preventing liquid from entering the interior of the isolation cover 509 and causing leakage. The overall performance is good.

[0041] In some embodiments, the scraping mechanism 6 includes a scraper plate 601, a return spring 602, and a limiting bevel gear 603. The scraper plate 601 is rotatably and obliquely mounted on one side edge of the fan-shaped sealing plate 508 via a rotating seat, and one side outer surface of the scraper plate 601 is in contact with one side outer surface of the filter plate 3. A plurality of return springs 602 are fixedly connected at equal intervals between the other side outer surface of the scraper plate 601 and one side outer surface of the fan-shaped sealing plate 508. A limiting bevel gear is fixed at the center position of one side of the filter plate 3. The scraping mechanism 6 also includes an abutting roller 604, a bevel gear rod 605, and an abutting rod 606. The bevel gear rod 605 is meshed with the limiting bevel gear 603 on the side near the shovel plate 601. The bevel gear rod 605 is rotatably mounted on the outside of one side of the sector-shaped sealing plate 508 via a bracket. The abutting rod 606 is fixed to the end of the bevel gear rod 605 away from the limiting bevel gear 603. The abutting roller 604 is rotatably mounted on the outside of one end of the shovel plate 601 near the abutting rod 606 via a bracket.

[0042] Combining 9 and Figure 10As shown, when the filter plate 3 rotates, the inclined scraper 601 on one side of the sector-shaped sealing plate 508 will scrape off impurities from the surface of the filter plate 3, preventing impurities from adhering and clumping, ensuring the flatness and cleanliness of the filter plate 3 surface, and ensuring that the filter plate 3 enters the sector-shaped sealing plate 508 smoothly. This prevents impurities from clumping on the surface of the filter plate 3 from contacting the sector-shaped sealing plate 508 and causing wear, thus affecting the sealing effect of the sector-shaped sealing plate 508. Simultaneously, the rotation of the filter plate 3 will drive the limiting bevel gear 603 to rotate synchronously, thereby driving a... The side-meshing bevel gear rod 605 rotates simultaneously, thereby driving the abutment rod 606 to rotate and the abutment roller 604 to drive the shovel plate 601 to descend. When the abutment rod 606 rotates to a certain angle and disengages from the abutment roller 604, it rebounds and resets in conjunction with the return spring 602. As the abutment rod 606 continues to rotate, the shovel plate 601 can reciprocate to rotate downward and rebound, causing the shovel plate 601 to vibrate and disengage a certain amount of impurities scraped off the surface of the shovel plate 601, achieving the effect of automatic cleaning of the shovel plate 601. The overall performance is good.

[0043] In some embodiments, the cleaning mechanism 7 includes a strong magnet 701, a limiting ring 702, and a groove 703. The strong magnet 701 is externally embedded at the edge of the filter plate 3 near the limiting bevel gear 603. The limiting ring 702 is fixed on the inner wall of the guide tube 2 near the scraper plate 601. The groove 703 is internally embedded in the limiting ring 702. The cleaning mechanism 7 also includes a second strong magnet 704, balls 705, and a scraper 706. The second strong magnet 704 is slidably engaged inside one side of the groove 703. Several balls 705 are rotatably mounted around the inner wall of the groove 703 at equal angles. The scraper 706 is fixed externally at the end of the second strong magnet 704 away from the first strong magnet 701. One side of the scraper 706 is in contact with one side of the inner wall of the guide tube 2. The first strong magnet 701 and the second strong magnet 704 attract each other.

[0044] Combination Figure 11 and Figure 12 As shown, when the filter plate 3 rotates, it drives the first strong magnet 701 to rotate synchronously. Through the corresponding attraction between the first strong magnet 701 and the second strong magnet 704, the rotation of the first strong magnet 701 drives the second strong magnet 704, which is slidably engaged in the sliding groove 703 inside the limiting ring 702 on one side, to rotate synchronously. This causes the scraper 706 on the side of the second strong magnet 704 to adhere to the inner wall of the guide tube 2 and rotate to scrape, cleaning the inner wall of the guide tube 2 and preventing impurities from accumulating and affecting the inner diameter of the guide tube 2, thus causing the liquid to flow unevenly. The setting of the ball bearing 705 makes the second strong magnet 704 rotate more smoothly and reduces friction.

[0045] Meanwhile, by setting a certain mutual attraction and movement distance between the magnets, even when there is a certain distance between the first strong magnet 701 and the second strong magnet 704, the first strong magnet 701 can still drive the second strong magnet 704 to move. This ensures that when the first strong magnet 701 follows the filter plate 3 to rotate into the fan-shaped sealing plate 508, it can still drive the second strong magnet 704 and the scraper 706 to rotate and move normally, ensuring smooth and stable operation. This avoids the filter plate 3 directly driving the scraper 706 to rotate, which would cause it to collide and jam with the fan-shaped sealing plate 508 and the isolation cover 504, resulting in good overall performance.
