Description

Disc cleaning device of disc pelletizer

Technical Field

The utility model belongs to the technical field of the pelletizing, concretely relates to disc cleaning device of disc pelletizer.

Background

The disk pelletizer is iron ore concentrate pelletizing equipment widely used in pelletizing plant. During production, iron ore concentrate is fed into a pelletizer, when a pelletizing disc rotates clockwise, the iron ore concentrate is lifted to the highest point and forms a mother ball, the mother ball is blocked by a scraper in the disc and falls, and the mother ball in the falling process adheres to the iron ore concentrate and grows up continuously; when the particle size reaches a certain size, the green ball passes over the edge of the disc and rolls out of the disc. Along with the production time, a part of iron ore concentrate can be gradually adhered to the edge of the disc, and if the iron ore concentrate is not cleaned in time in production, the green pellets can be adhered with some powder when being discharged from the disc. The condition can affect the screening efficiency of the green pellets in the roller type screening machine and the air permeability of the pellet layer during the preheating and roasting operation of the green pellets, and is not beneficial to the stability of pellet quality; meanwhile, the load of the disc pelletizer can be increased under the condition, and the normal operation of the equipment is influenced. At present, the method for treating the iron ore concentrate adhered to the edge of the disc is mainly to arrange a movable scraper or a brush at a certain position of the upper left corner of the edge of the disc. When the scraper is arranged, the contact surface between the edge of the disc and the scraper is frequently abraded, so that the cleaning effect of the scraper is influenced; when the brush is arranged, a power supply and a motor for rotating the brush need to be installed, and the installation cost is increased.

Disclosure of Invention

The utility model aims at providing a disc cleaning device of balling disc need not to arrange drive arrangement, and the clearance is respond well.

The utility model aims at realizing through the following technical scheme:

the utility model discloses a disc cleaning device of a disc pelletizer, which comprises a disc rotating around the vertical axis of a disc core and a fixed knife rest of a central scraper positioned above the disc core, and is characterized by also comprising a horizontal shaft, two frame plates with hinged round holes, two inclined rods, a sector plate, an arc plate, a disc edge steel wire brush and a disc edge steel wire brush;

the horizontal axis rotate and cup joint in the through-hole of stationary knife rest, two frame boards 1 cup joint the both ends at the horizontal axis through the articulated round hole symmetry parallel of its upper end portion, two down tube symmetries lean out the setting, one end respectively with two frame board lower extreme rigid couplings, the other end respectively with two straight flange fixed connection of sector plate, the arc paste perpendicularly and lean on and fix at the outer arc line end of sector plate, be equipped with the dish along the steel brush on sector plate and dish along the surface of leaning on, be equipped with the dish limit steel brush on the surface that arc pasted with the dish limit.

Furthermore, the curvature radius of the outer arc line of the sector plate is more than or equal to that of the outer edge of the disc; the curvature radius of the inner arc line of the sector plate is less than or equal to that of the inner edge of the disc.

Furthermore, the frame plate, the diagonal rods, the sector plates and the arc-shaped plates are all made of aluminum materials.

Compared with the prior art, the utility model has the advantages that:

1) the utility model does not need to arrange driving devices such as a motor, when the disc rotates clockwise, the disc edge steel wire brush of the sector plate is in surface contact with the disc edge, the disc edge steel wire brush of the arc plate is in contact with the outer edge of the disc, thus cleaning the disc edge and the outer edge of the disc simultaneously, when the disc edge steel wire brush is worn, the sector plate is in close contact with the disc edge by self weight, the cleaning effect is ensured, and the service life is prolonged;

2) the utility model discloses processing simple manufacture is easy, and the convenience is changed in the installation maintenance.
