[0002] With the upgrading of my country's manufacturing industry and the improvement of automation technology, various chemical production lines have continuously improved their requirements for product quality levels, and thus the requirements for material monitoring accuracy and measurement parameters are also constantly increasing. Against this background, the demand and application scenarios for various advanced instruments and meters in industries such as petrochemicals are constantly increasing. Liquid level measurement technology is one of the core technologies in various chemical productions. Accurately mastering the height of the liquid level in each link of production is equivalent to realizing the real-time monitoring function of materials in chemical reactions, which is extremely important for controlling reaction rates, adjusting material ratios, and ensuring stable production. There are many working conditions that require liquid level measurement in chemical production, and common ones include liquid storage tanks, reactors, and other environments.

[0003] However, in the prior art, when using radar liquid level meter probes to detect the liquid level in the reactor, it was found that the sediment and dirt formed inside the reactor during long-term operation would affect the measurement accuracy of the radar level meter. Some radar liquid level meter probes also use a scraping method to remove the sediment and dirt adsorbed on the probe surface. However, the scraped sediment and dirt are not cleaned in time, resulting in the sediment and dirt to solidify quickly and continue to adsorb on the probe surface.

[0004] Therefore, an anti-fouling radar liquid level meter probe is proposed to solve the above problems. Utility Model Content

[0013] 1. The utility model rotates and tightens the external threaded mounting tube of the anti-fouling radar liquid level meter probe with the internal thread above the reactor, and connects the probe with an external power supply device, which provides power to the radar liquid level meter probe body, the motor and the electric valve. One end of the water main is connected to the water pipe, and the external controller is electrically connected to the radar liquid level meter probe body, the motor and the electric valve. The start and stop of the radar liquid level meter probe body and the motor are controlled by the external controller, and the opening and closing of the electric valve are controlled by the external controller.

When there is no other substance in the reactor, workers can start the motor and open the electric valve regularly through an external controller. The driving gear rotates with the output end of the motor driven by the rotating shaft, so that the driven gear is driven to rotate due to the meshing connection between the driving gear and the driven gear. The scraper block will also rotate around the fluoroplastic lens with the driven gear. The scraper block fits tightly to the surface of the fluoroplastic lens, and the precipitate and dirt adsorbed on the surface of the fluoroplastic lens are scraped during the rotation of the scraper block. This design avoids the precipitate and dirt formed inside the reactor during long-term operation affecting the measurement accuracy of the radar level meter.

[0028] Specifically: the driving gear 204 rotates along with the output end of the motor 206 driven by the rotating shaft 205, so that the driven gear 201 is driven to rotate due to the meshing connection between the driving gear 204 and the driven gear 201, and the scraping block 203 also rotates around the fluoroplastic lens 101 along with the driven gear 201.

The scraping block 203 is tightly fitted with the surface of the fluoroplastic lens 101. During the rotation of the scraping block 203, the sediment and dirt adsorbed on the surface of the fluoroplastic lens 101 are scraped. This design prevents the sediment and dirt formed inside the reactor during long-term operation from affecting the measurement accuracy of the radar level meter. At the same time, the water inside the water pipe passes through the water main pipe 302, the electric valve 303, the water branch pipe 304 and the nozzle 305, and is sprayed from the multiple nozzles 305 to remove the sediment and dirt scraped off the surface of the fluoroplastic lens 101 and the electric valve 303, so as to avoid the sediment and dirt scraped off not being cleaned in time, resulting in the sediment and dirt being quickly solidified and continuing to be adsorbed on the surface of the fluoroplastic lens 101.
