Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to the technical field of stirring equipment, concretely to a magnetic induction scraper. BACKGROUND
[0002] When mixing a plurality of components of semi-solid or fluid material, a wall scraping stirring device needs to be used. Since the raw liquid of the material is relatively dense, it is easy to stick to the inner surface of the tank wall, so the existing stirring frame will increase a plurality of scrapers at the outermost edge. This stirring form is called wall scraping stirring. During the material stirring process, the scraper rotates closely against the inner surface of the tank wall.
[0003] At present, the scrapers on the market are mostly hinge structures connected by pins or bolts, which leads to the following problems during the rotating stirring process:
[0004] 1. The hinge structure is free to rotate, which may not fully open the scraper, so that the scraper cannot be attached to the tank wall, resulting in unsatisfactory wall scraping stirring effect, uneven mixing of the material in the tank, and poor material mixing effect.
[0005] 2. The scraper of the hinge structure is attached to the tank wall surface by the counter thrust of the material. The counter thrust of the scraper depends on the stirring speed, the area of the scraper, and the viscosity of the material. The counter thrust (5-50KG) of the scraper is the friction force of the scraper on the tank wall. The greater the counter thrust, the greater the friction force, which causes damage to the tank surface by the scraper, affecting the service life of the tank.
[0006] 3. The scraper of the hinge structure is attached to the tank wall surface by the counter thrust of the material. When the material is mixed, the liquid will splash onto the surface of the tank above the liquid surface. The material attached to the surface of the tank without liquid will not be scraped by the scraper, resulting in poor material mixing effect. INVENTION CONTENTS
