The thin material liquid is passed from the feed pipe 3 into the tower body 1 through the sprayer and is separated into mist. The water is dropped and dispersed in the hot air flow, so that the water evaporates quickly to obtain a solid product. When the inner wall of the tower body 1 needs to be cleaned, the first motor 56 can be started, and the output shaft of the first motor 56 drives the threaded rod 54 to rotate. Since the cleaning brush 51 is threadedly connected with the threaded rod 54, and the cleaning brush 51 slides on the round rod 53, the rotation of the threaded rod 54 will drive the cleaning brush 51 to slide, and then the inner wall of the tower body 1 is cleaned, thereby avoiding the situation that manual cleaning not only increases the work intensity, but also takes a long time for manual cleaning, which will affect the production process. A cavity is provided inside the cleaning brush 51, and a plurality of water spray holes 57 are provided on the cleaning brush 51. A water inlet pipe 513 is provided on the tower body 1, and one end of the water inlet pipe 513 is fixedly connected to the cleaning brush 51 The water inlet pipe 513 is connected to the cavity of the cleaning brush 51. The water inlet pipe 513 is a hose. The water inlet pipe 513 has a suitable length in the tower body 1. When the cleaning brush 51 cleans the inner wall of the tower body 1, the water inlet pipe 513 can be connected to the water source, and the water is passed into the cavity of the cleaning brush 51 through the water inlet pipe 513, and then sprayed on the inner wall of the tower body 1 through the water spray hole 57 to enhance the cleaning effect. A slide groove 58 is provided on the lower surface of the cleaning brush 51. A slide rod 59 is slidably connected in the slide groove 58. A scraper 510 is fixedly connected to the slide rod 59. One side of the scraper 510 contacts the inner wall of the tower body 1.

[0030] Working principle: the thin liquid is introduced into the tower body 1 from the feed pipe 3 through the sprayer, and is separated into droplets, which are dispersed in the hot air flow, so that the water evaporates quickly to obtain a solid product. When the inner wall of the tower body 1 needs to be cleaned, the first motor 56 can be started, and the output shaft of the first motor 56 drives the threaded rod 54 to rotate. Since the cleaning brush 51 is threadedly connected with the threaded rod 54, and the cleaning brush 51 slides on the round rod 53, the rotation of the threaded rod 54 will drive the cleaning brush 51 to slide, thereby cleaning the inner wall of the tower body 1. The cleaning is performed to avoid the situation that manual cleaning not only increases the work intensity, but also takes a long time, which will affect the production process. When the cleaning brush 51 cleans the inner wall of the tower body 1, the water inlet pipe 513 can be connected to the water source, and the water is passed into the cavity of the cleaning brush 51 through the water inlet pipe 513, and then sprayed on the inner wall of the tower body 1 through the water spray hole 57, so as to enhance the cleaning effect. The sliding rod 59 can be used to make the scraper 510 move in a circle along the cleaning brush 51 to clean the tower body 1. The fixed materials attached to the inner wall are scraped off, and the cleaning brush 51 cleans the scraped area again to enhance the cleaning effect. The sliding rod 59 can be driven to slide in the sliding groove 58 by rotating the telescopic rod 511, and the connecting plate 514 is located at the lower end of the telescopic rod 511. Therefore, when the cleaning brush 51 drives the scraper 510 to move up and down, the telescopic rod 511 can be extended and retracted, and the first motor 56 is started. The output shaft of the first motor 56 can drive the telescopic rod 511 to rotate under the action of the belt 512. Energy can be saved. The debris scraped off by the scraper 510 will fall into the collecting bucket 62, and the fine powder will be filtered out by the filter plate 63. The larger lumps will remain on the filter plate 63. Then the second motor 65 will be started. The output shaft of the second motor 65 will drive the pressure roller 64 to rotate, and the larger lumps will be crushed. Several crushing plates 66 can enhance the crushing effect of the pressure roller 64 on the lumps. The guide plate 67 can guide the debris scraped off by the scraper 510 to prevent the debris from falling to the place where the pressure roller 64 cannot crush.
