Description

TECHNICAL FIELD

[0001] The utility model belongs to pellet production equipment technical field, especially relate to a kind of buffer type material scraper for disc pelletizer disc edge. BACKGROUND

[0002] The working principle of disc pelletizer is that motor and speed reducer drive disc to rotate, and the mixture of binder, dust and iron ore concentrate is filled into the disc, the material is rolled into ball core by adding water drop and mist in the disc, the ball core is gradually grown into green ball by rolling in the disc, and the qualified green ball is discharged from the lower left corner of the disc and enters the next process under the action of gravity and centrifugal force.

[0003] Since the binder is added in the mixture, the mixture has certain viscosity, and when the disc pelletizer works, a layer of material will adhere to the surface of the disc edge, and too much material adhering to the disc edge will directly affect the discharge of qualified green ball, and the over-standard ball in the disc pelletizer will hinder the normal discharge of other qualified green ball, causing vicious cycle, and serious material adhering to the disc edge will greatly reduce the green ball output and directly affect the pellet output, and the surface friction of the disc edge after material adhering increases, and part of the green ball is brought down to the equipment and ground with the disc during the discharge of qualified green ball, which not only pollutes the environment, but also increases the cleaning labor intensity of operators.

[0004] In terms of handling the problem of material adhering to the disc edge, some domestic enterprises currently use shovel to clean the material or install a scraping plate on the disc edge. Manual cleaning of the material will cause the shovel to be bounced or stuck when encountering the material, and there is a great safety hazard during cleaning. The scraping plate is installed at a fixed position, and relies on the rotation of the disc to handle the material adhering to the disc edge, but due to the concentricity, ellipticity of the disc and vibration generated during operation, the disc edge swings up and down, so that the scraping plate cannot contact the disc edge for a period of time, causing incomplete cleaning of the material adhering to the disc edge, or the scraping plate wears out quickly. SUMMARY

[0005] The utility model aims at the technical problem of material adhering to the disc edge of disc pelletizer, and provides a buffer type material scraper for disc pelletizer disc edge. The scraper has a buffering effect, and can maintain a fixed distance with the disc edge under the condition of the disc edge swinging up and down, without causing incomplete cleaning of the material adhering to the disc edge or the scraping plate wearing out quickly. The problems existing in cleaning the material adhering to the disc edge of disc pelletizer are reduced, which helps to improve the qualified rate of green ball and the output of pellet, and reduce the labor intensity of operators in cleaning the material.
