TECHNICAL FIELD
[0001] The utility model relates to material drying technical field, concretely is a kind of roller scraper dryer. BACKGROUND
[0002] Roller scraper dryer is a kind of equipment with inner heating conduction rotation, which continuously dries the material adhered to the outer wall of the simple body. When the roller scraper dryer is working, the rotating roller passes through the lower chute, adheres to the thick material film, and the heat is transmitted to the inner wall of the roller through the pipeline. The heat is conducted to the outer wall of the roller and further conducted to the material film, so that the water in the material film evaporates and dehumidifies. The material is dried. The dried material is scraped off by the scraper on the surface of the roller, falls into the discharge port and is concentrated and packaged.
[0003] The existing roller scraper dryer usually lacks a cloth film roller. Some dryers with cloth film rollers have a fixed distance between the cloth film roller and the drying cylinder. The material on the outside of the drying cylinder is pressed to a uniform thickness by the cloth film roller. However, the thickness of the material adhered to the cloth film roller varies for different types of material, which limits the use of the existing roller scraper dryer. The existing roller scraper dryer usually has a horizontal scraper or uses a scraper rod to scrape the material. This type of arrangement results in poor scraping effect on the outside of the drying cylinder and incomplete scraping. The horizontal scraper is prone to accumulate scraped material on the scraper, which is time-consuming and troublesome to clean. Therefore, we propose a roller scraper dryer. UTILITY MODEL CONTENTS
