Its excellent sealing performance and anti-leakage characteristics ensure the stable operation of the equipment in extreme environments such as high temperature, high pressure and corrosion resistance. Compared with traditional glass plate (tube) level gauges, magnetic flap level gauges not only overcome the defects of insufficient indication clarity and fragility, but also achieve full-process blind spot measurement through its unique design, ensuring the clarity of the display and the accuracy of the measurement, thus covering a wider range of measurements.

[0033] See also Figures 1 to 4 The anti-blocking device of the magnetic flap liquid level gauge comprises a magnetic flap liquid level gauge body 1, a liquid outlet pipe 2 connected to the inner cavity of the magnetic flap liquid level gauge body 1 is fixedly installed on the upper end of the magnetic flap liquid level gauge body 1, a liquid inlet pipe 3 connected to the inner cavity of the magnetic flap liquid level gauge body 1 is fixedly installed on the lower end of the magnetic flap liquid level gauge body 1, and a filtering mechanism 4 is arranged in the inner cavity of the liquid inlet pipe 3.

[0034] The filter mechanism 4 includes a filter component 41, an impurity cleaning component 42 and an impurity collecting component 43. The filter mechanism 4 includes a filter component 41, an impurity cleaning component 42 and an impurity collecting component 43. This design is intended to comprehensively solve the clogging problem of the magnetic flap level gauge when handling liquids containing impurities. The filter component 41 is responsible for preliminary filtering of impurities to ensure the purity of the liquid; the impurity cleaning component 42 regularly cleans the impurities on the filter cylinder to ensure that the filtering effect is sustained and effective; the impurity collecting component 43 is responsible for collecting and processing the cleaned impurities to achieve centralized management of impurities. The three work together to effectively improve the measurement accuracy and operating stability of the magnetic flap level gauge.

[0035] The filter assembly 41 includes a mounting ring 411 fixedly mounted in the inner cavity of the liquid inlet pipe 3, a conical filter screen cylinder 412 is fixedly mounted on the outer side of the mounting ring 411, and a substrate 413 is fixedly mounted on one end of the conical filter screen cylinder 412 away from the mounting ring 411. The filter assembly 41 is fixed in the liquid inlet pipe 3 through the mounting ring 411, and the conical filter screen cylinder 412 on the outer side uses a unique conical design and stainless steel material to effectively block impurities in the liquid and prevent them from entering the magnetic flap level gauge body 1, thereby ensuring measurement accuracy and stable operation. The substrate 413 serves as a support to ensure the stability of the filter assembly structure, and the three work together to complete the initial liquid filtration process.

[0036] Furthermore, the mounting ring 411 is adapted to the liquid inlet pipe 3, wherein the outer diameter of the mounting ring 411 is equal to the inner diameter of the liquid inlet pipe 3. The mounting ring 411 is adapted to the liquid inlet pipe 3, and its outer diameter is equal to the inner diameter of the liquid inlet pipe 3, thereby ensuring that the filter assembly 41 is firmly installed in the liquid inlet pipe 3, with seamless fit to prevent liquid from bypassing, ensuring that the conical filter mesh cylinder 412 can effectively intercept impurities, and maintaining the measurement accuracy and stable operation of the magnetic flap level gauge.

[0037] Furthermore, the conical filter screen cylinder 412 is made of stainless steel mesh, and the main function of the conical filter screen cylinder 412 is to effectively prevent impurities in the liquid from entering the magnetic flap level gauge by utilizing its high strength and corrosion resistance to ensure measurement accuracy. The stainless steel material can withstand liquid erosion for a long time without being easily damaged, maintaining the filtering effect, thereby extending the service life of the magnetic flap level gauge.

[0038] Furthermore, the impurity cleaning component 42 includes a shaft 421 rotatably connected to the base plate 413 and coaxial with the liquid inlet pipe 3, a driven bevel gear 422 is fixedly installed at one end of the shaft 421, a driving bevel gear 423 is meshed with the outer side of the driven bevel gear 422, a rotating rod 424 rotatably connected to the liquid inlet pipe 3 is fixedly installed on the driving bevel gear 423, and a servo motor 425 is fixedly installed at one end of the rotating rod 424 away from the driving bevel gear 423. A motor fixture 426 fixedly connected to a servo motor 425 is fixedly mounted on the outside of the conical filter screen cylinder 412, an inner cleaning scraper 427 is fixedly mounted on one end of the shaft 421 located inside the conical filter screen cylinder 412, and an outer cleaning scraper 428 is fixedly mounted on one end of the shaft 421 located outside the conical filter screen cylinder 412. The impurity cleaning assembly 42 drives the rotating rod 424 through the servo motor 425, driving the active bevel gear 423 to rotate, thereby causing the driven bevel gear 422 and the shaft 421 to rotate synchronously. The inner cleaning scraper 427 and the outer cleaning scraper 428 on the shaft 421 fit tightly against the inner and outer walls of the conical filter screen cylinder 412, scraping and cleaning attached impurities during rotation. This design ensures that the conical filter screen cylinder 412 continues to filter effectively, prevents clogging, and maintains the measurement accuracy and stable operation of the magnetic flap level gauge.

[0039] Furthermore, the motor fixing part 426 is composed of two pipe rings, two right-angle frames and a motor ring. The two pipe rings are fixedly installed on the liquid inlet pipe 3, the right-angle frame is fixedly installed between the pipe ring and the motor ring, and the motor ring is fixedly installed on the servo motor 425. The motor fixing part 426 is composed of a pipe ring, a right-angle frame and a motor ring, and is firmly installed on the outside of the liquid inlet pipe 3. It is fixed to the liquid inlet pipe through the pipe ring. The right-angle frame connects the pipe ring and the motor ring, and the motor ring fixes the servo motor 425, ensuring that the motor runs stably without taking up extra space, thereby improving the practicality and convenience of the anti-blocking device of the magnetic flap liquid level gauge.

[0040] Furthermore, the inner cleaning scraper 427 and the outer cleaning scraper 428 are adapted to the conical filter mesh cylinder 412, wherein the inner cleaning scraper 427 and the outer cleaning scraper 428 are in contact with the conical filter mesh cylinder 412, and the inner cleaning scraper 427 and the outer cleaning scraper 428 are in close contact with and adapted to the conical filter mesh cylinder 412, and are driven to rotate by the servo motor 425 to thoroughly scrape and clean impurities attached to the inner and outer walls of the conical filter mesh cylinder 412, thereby ensuring the continuous and efficient filtering function of the filter, avoiding clogging of the magnetic flap level gauge, and ensuring measurement accuracy and stable operation.

[0041] Furthermore, the impurity collecting component 43 includes an impurity drain pipe 431 fixedly mounted on the liquid inlet pipe 3 and connected to the inner cavity of the liquid inlet pipe 3. The lower end of the impurity drain pipe 431 is threadedly connected to an impurity collecting box 432. The impurity collecting component 43 is connected to the inner cavity of the liquid inlet pipe 3 through the impurity drain pipe 431, ensuring that the scraped impurities are discharged smoothly, and the impurities are centrally collected and processed with the help of the threaded impurity collecting box 432, which not only avoids the problem of filter clogging caused by impurity accumulation, but also facilitates regular cleaning and maintenance, thereby improving the practicability and convenience of the device.

[0042] Furthermore, the impurity discharge pipe 431 is located directly in front of the conical filter mesh cylinder 412, ensuring that the scraped impurities can fall smoothly into the discharge pipe, avoiding the accumulation of impurities around the filter mesh cylinder and causing blockage again, and at the same time facilitating the impurities to enter the impurity collection box 432 through the impurity discharge pipe 431, thereby achieving smooth discharge and centralized collection of impurities, and enhancing the effectiveness and practicality of the anti-blocking device.

[0043] Working principle: When using the magnetic flap level gauge anti-blocking device, first connect it closely to the liquid container to ensure that the connection is stable and the sealing is good. Due to the effect of the communicating vessel principle, the liquid in the liquid container, such as water, will flow smoothly from the liquid inlet pipe 3 at the lower end into the interior of the magnetic flap level gauge body 1.

[0044] Specifically, when the liquid enters the liquid inlet pipe 3, it will first be intercepted by the filter assembly 41. The filter assembly is composed of a mounting ring 411, a conical filter screen cylinder 412 and a base plate 413, which work together to perform preliminary filtering on the liquid. Among them, the conical filter screen cylinder 412, with its unique conical design and stainless steel mesh material, effectively blocks impurities that may exist in the liquid, preventing these impurities from entering the magnetic flap level gauge body 1, thereby ensuring the measurement accuracy and stable operation of the level gauge.

[0045] However, as time goes by, some impurities will inevitably adhere to the conical filter screen cylinder 412, affecting the filtering effect. For this reason, the device is specially equipped with an impurity cleaning component 42. When it is necessary to clean the impurities, it is only necessary to start the servo motor 425 regularly, which drives the active bevel gear 423 to rotate through the rotating rod 424, and then drives the driven bevel gear 422 and the shaft 421 to rotate synchronously. The rotation of the shaft 421 drives the rotation of the inner cleaning scraper 427 and the outer cleaning scraper 428, which are tightly fitted to the inner and outer walls of the conical filter screen cylinder 412, and the impurities attached thereto are thoroughly scraped and cleaned.

[0046] Under the action of gravity and the clever combination of the conical surface design of the conical filter screen cylinder 412, the scraped impurities will gradually settle and fall into the impurity discharge pipe 431 in front. The impurity discharge pipe 431 is a channel for the discharge of impurities, and its position is just in front of the conical filter screen cylinder 412, ensuring that the impurities can be discharged smoothly. Finally, these impurities will fall into the impurity collection box 432, realizing the centralized collection and treatment of impurities.

[0047] The design of the entire anti-blocking device not only takes into account the functionality of filtering and cleaning, but also fully considers practicality and convenience. For example, the ingenious design of the motor fixing member 426 enables the servo motor 425 to be firmly installed on the outside of the liquid inlet pipe 3, which not only ensures the stable operation of the motor, but also avoids occupying additional space. At the same time, the threaded connection design between the impurity collection box 432 and the impurity discharge pipe 431 makes the disassembly and cleaning of the collection box extremely simple and convenient.

[0048] In summary, the magnetic flap level gauge anti-blocking device effectively solves the problem that the magnetic flap level gauge is prone to blockage when handling liquids containing impurities through its unique filtering, cleaning and collection mechanisms, improves the measurement accuracy and operational stability of the level gauge, and provides a strong guarantee for the company's safe production and efficient operation.

[0049] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent replacements or modifications made based on the present invention to solve basically the same technical problems and achieve basically the same technical effects are all included in the protection scope of the present invention.
