Description

Dedusting ash cold-pressed pellet production device Technical Field The application relates to a dust-removing pressed pellet recovery technology in ferroalloy production, in particular to a dust-removing cold-pressed pellet production device. Background The ferroalloy can generate a large amount of dust and ash in the production and processing process, and valuable metals such as iron, manganese and the like in the ferroalloy are recovered by pressing the ferroalloy into balls after cleaning and collecting the ferroalloy by using dust removing equipment. The pressed and recovered pellets can replace part of iron ore raw materials, so that the consumption of slag and lime is reduced, and the waste of resources is reduced. In the existing production of the fly ash cold-pressed pellets, the pellets are pressed by a pair of roller ball presses, the pair of roller ball presses consists of a pair of pressing rollers which rotate in opposite directions, hemispherical female dies which can be closed are arranged on the rollers of the pressing rollers, and powdery materials are pressed into pellets by mechanical pressure. In the existing cold-pressed pellet production device, in the long-time mass pellet pressing production, the problem that the pellets are easy to demould and difficult to adhere to the inside of a female die and residual accumulated materials in the female die are easy to occur, so that the yield of the pellets is influenced, the abrasion of the female die is also increased, and the service life of equipment is influenced. Disclosure of utility model The application provides a dedusting ash cold-pressed pellet production device which is used for solving the problems that pellets are easy to remain and accumulate in a female die after being adhered in the conventional cold-pressed pellet production device and difficult to demould. The application provides a dust-removing cold-pressed pellet production device which comprises a pair of pressing rolls rotating in opposite directions, wherein the pressing rolls are rotationally connected with a frame body fixed on the ground, hoppers fixed with the frame body are arranged above the pressing rolls, spraying boxes attached to the pressing rolls are respectively arranged below the two pressing rolls, spraying pipes with upward openings are arranged in the spraying boxes, an atomizer used for atomizing a release agent is arranged at the side ends of the spraying boxes, and mist outlets of the atomizer are respectively communicated with the spraying pipes in the two spraying boxes through pipelines. Optionally, two separate baffle plates are fixed with respectively in the spraying case, separate clearance chamber is separated to the baffle plate with the one side of the spraying case that is close to blanking point, and the clearance intracavity swivelling joint has the round brush that the upper end can stretch into in the die of compression roller, the round brush passes through motor drive. Optionally, a door capable of opening and closing is arranged below the rolling brush.
