Description

TECHNICAL FIELD

[0001] The utility model relates to mixing and stirring equipment technical field especially is related to a scraper holder wear -resisting reinforcing device. BACKGROUND

[0002] The strong mixer is a kind of equipment widely used in industrial production, and its main function is to mix different raw materials with strong force to ensure that the raw materials are fully and uniformly mixed together to meet the requirements of subsequent production process. In the internal structure of the strong mixer, a wall scraper needs to be in close contact with the inner wall of the strong mixer. During the operation of the equipment, as the internal raw materials continuously move and roll, the scraper, supported by the wall scraper holder, will scrape off the raw materials attached to the barrel wall, so that the raw materials continuously participate in the mixing process.

[0003] In actual production, the mixed materials mostly contain water, which makes the materials have strong adhesion and easily form a hard mass at the bottom of the mixing barrel. The bottom of the scraper holder will be subjected to a large impact force from the raw materials with large force, and this frequent and strong impact will cause the scraper holder to be easily mechanically worn. Under the extrusion of the bottom material, the scraper holder will be bent and deformed to tilt away from the barrel wall, and cannot effectively clean the adhered material. Excessive accumulation of materials at the lower end and bottom of the inside of the mixing barrel will affect the operation of the equipment. Moreover, the materials will be extruded by the side scraper for a long time, and the hardened material will be more difficult to clean. In addition, some raw materials contain corrosive substances, and the bottom of the scraper holder is easily corroded. After the bottom of the scraper holder is corroded and worn, the scraper holder needs to be replaced as a whole, which results in a service life of the wall scraper holder made of ordinary manganese steel usually only 3-4 months. This not only increases the equipment maintenance cost and downtime, but also affects the overall production efficiency.
