Description

Technical Field

[0001] The utility model belongs to the technical field of pellet production equipment, in particular to a disc pelletizing machine anti-disc edge hanging device. Background Art

[0002] The disc pelletizing machine is a widely used pelletizing equipment for sintered ore. Its working principle is that a motor and reducer drive the disc to rotate. A mixture of binder, dust removal ash, iron ore concentrate, and other materials is filled into the disc. The materials are then rolled into ball cores by the addition of dripping or mist water. The ball cores gradually grow and form green balls as they roll inside the disc. Qualified green balls are discharged from the lower left corner of the disc under the action of gravity and centrifugal force and enter the next process.

[0003] Since binders are added to the mixture, the mixture has a certain viscosity. When the disc pelletizer is working, a layer of material will adhere to the surface of the disc edge of the pelletizer. Too much material hanging on the disc edge will directly affect the discharge of qualified raw balls. These raw balls continue to roll in the disc pelletizer until they are discharged and become substandard balls. Moreover, the substandard balls in the pelletizer will also hinder the normal discharge of other qualified raw balls, causing a vicious circle. Serious material hanging on the disc edge will greatly reduce the raw ball output and directly affect the output of pelletized ore. After the material is hung on the disc edge, the surface friction increases. When the qualified raw balls are discharged, some of the raw balls are brought down to the equipment and the ground as the pelletizer rotates, which not only pollutes the environment, but also increases the cleaning labor intensity of the operator. In addition, the gap on the upper edge of the disc lining is easy for materials to enter, causing the disc lining to deform and affecting production.

[0004] To address the problem of material hanging on the edge of the pelletizing machine disc, domestic companies currently mostly use manual shovels to clean the material or install scrapers on the disc edge. Manually cleaning the material hanging can cause the shovel to bounce or get stuck when encountering the material hanging, posing a significant safety hazard during cleaning. Scrapers are installed in a fixed position and rely on the rotation of the pelletizing disc to remove the material hanging on the disc edge. However, due to various factors such as the concentricity and ellipticity of the pelletizing disc and the vibration generated during operation, the disc edge can swing up and down, causing the scraper to lose contact with the disc edge for a period of time. This results in incomplete cleaning of the material hanging and rapid wear of the scraper and disc edge. Summary of the Invention

[0005] The purpose of this utility model is to solve the problem of material hanging on the disc edge of the existing pelletizing machine and provide a device to prevent material hanging on the disc edge of the disc pelletizing machine. The utility model can reduce material hanging on the disc edge of the disc pelletizing machine, improve the qualified rate of raw balls and the output of pellets, and reduce the labor intensity of operators cleaning bulk materials.
