Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to bottom scraper blade technical field, concretely relates to a new bottom scraper blade of strong mixer. BACKGROUND
[0002] In modern industrial production, the strong mixer is widely used in many fields, such as the production of concrete, dry powder mortar and the like in the building material industry, the mixing of various chemical raw materials in the chemical industry, and the uniform stirring of different ingredients in the food processing industry. The efficient operation of the strong mixer depends on the performance of its key component, the rake blade. The rake blade of the strong mixer on the market has exposed many problems in actual use. From the perspective of wear, a large amount of hard materials such as sand and stone will produce intense friction on the rake blade during the production of building materials. Taking the production of concrete as an example, during each batch of stirring process, sand and stone particles continuously contact and scrape the surface of the rake blade, which will cause obvious wear marks in a short time. With the passage of time, the shape of the rake is gradually destroyed, and the edge of the blade becomes blunt, which directly leads to the fact that the materials cannot be fully turned over and mixed during the stirring process, resulting in uneven mixing, which seriously affects the product quality.
[0003] Therefore, in the chemical industry, when mixing some raw materials with high hardness and large particles, these raw materials will hit the rake blade at high speed during the stirring process, which not only reduces the service life of the equipment, but also frequently causes production interruption, increases maintenance cost and production cycle.
[0004] In some scenes involving chemical synthesis or mixing of corrosive materials, such as the production of electroplating liquid additives, the chemicals therein will chemically react with the metal material of the rake blade, gradually corroding the rake and the blade, weakening the structural strength, and causing the rake blade to fail prematurely.
