Description

Technical Field

[0001] This utility model relates to the field of centrifugal sprayer technology, and in particular to a scraping device for a centrifugal sprayer. Background Technology

[0002] Centrifugal spray dryers are equipped with centrifugal atomizers. Centrifugal spray dryers are one of the most widely used dryers in industrial production. The liquid feed is fed into the centrifugal atomizer, where it is swirled into droplets by centrifugal force. High-temperature gas is then introduced into the dryer to rapidly dehydrate the droplets, thus achieving the drying of the liquid feed within the dryer.

[0003] Extensive research revealed that existing technologies, such as the centrifugal spray dryer with application number CN202123029034.8, while preventing material adhesion on the inner wall of the centrifugal spray dryer and facilitating full contact between hot air and material to improve drying efficiency, still suffer from some material adhering to the outlet horizontal pipe during actual operation, potentially causing blockage of the outlet. Therefore, further improvements are needed.

[0004] Therefore, it is necessary to provide a scraping device for centrifugal sprayers to solve the above-mentioned technical problems. Utility Model Content

The device features a clearance hole. Through the coordinated use of a distribution box, heating wire, fan, and air outlet, it facilitates maximum contact between the material and hot air during drying, improving efficiency. During operation, the fan, heating wire, and centrifugal atomizer are activated, allowing the material to enter the device body through the atomizer. Then, heated gas from inside the distribution box is blown into the device body through the air outlet by the fan, contacting the splashed material inside for drying. This method is simple to operate; throughout the process, the material only contacts the inner wall of the device body and not the gaseous material, thus improving drying efficiency.

By setting the drive motor, cleaning rod, side scraper, and upper scraper to work together, when the device body is working, the drive motor is started, and then the drive motor drives the cleaning rod to rotate through the main shaft. Then the cleaning rod drives the side scraper and the upper scraper to rotate, so that the side scraper scrapes the material adsorbed on the inner wall of the device body, and the upper scraper scrapes the material adsorbed on the top of the interior of the device body, thus preventing the material from clogging the air outlet.

[0012] Compared with related technologies, the scraping device for a centrifugal sprayer provided by this utility model has the following beneficial effects:

[0013] Compared with existing technologies, this centrifugal sprayer uses a scraping device that, through the coordinated use of a distribution box, heating wire, fan, and air outlet, facilitates the simultaneous drying of objects and maximizes contact between the object and hot air, thus improving its working efficiency. During operation, the fan, heating wire, and centrifugal atomizer are activated, allowing the material to enter the device body through the centrifugal atomizer. Then, heated gas inside the distribution box, driven by the fan, is blown into the device body through the air outlet to contact the splashed material inside, thus drying it. The operation is simple. During the entire working process, the material only comes into contact with the inner wall of the device and does not come into contact with gaseous objects, thereby improving the drying efficiency of the material.

[0026] This type of centrifugal sprayer uses a scraping device. During operation, the fan 10, heating wire 19, and centrifugal atomizer 11 are activated, allowing the material to enter the device body 1 through the centrifugal atomizer 11. Then, heated gas inside the distribution box 9 is blown into the device body 1 through the outlet 18 by the fan 10, contacting the splashed material inside the device body 1 for drying.

To improve the drying efficiency of materials, the drive motor 6, cleaning rod 12, side scraper 16, and upper scraper 15 are used in combination. When the device body 1 is working, the drive motor 6 is started, and then the drive motor 6 drives the cleaning rod 12 to rotate through the main shaft 14. After that, the cleaning rod 12 drives the side scraper 16 and the upper scraper 15 to rotate, so that the side scraper 16 scrapes the material adsorbed on the inner wall of the device body 1, and the upper scraper 15 scrapes the material adsorbed on the top of the inside of the device body 1, thus preventing the material from clogging the air outlet 18.
