Metallurgical auxiliary material screening type anti-blocking discharging device

Abstract

The invention discloses a metallurgical auxiliary material screening type anti-blocking discharging device. The metallurgical auxiliary material screening type anti-blocking discharging device comprises a discharging barrel and an anti-blocking device, wherein a feeding hopper is arranged at the top end of the discharging barrel; a cylindrical discharging outlet is formed in the bottom end of the discharging barrel and located above a ball press machine. The anti-blocking device comprises a motor, a transmission shaft, a screen and an anti-blocking paddle, wherein the motor is located at the top end of the discharging barrel; the transmission shaft is located inside the discharging barrel and connected with the motor; the screen is in a circular ring shape and fixed to the upper portion of the transmission shaft; the outer diameter of the screen is smaller than the inner diameter of the discharging barrel; the anti-blocking paddle is in a spirally ascending shape and fixed to the lower end of the transmission shaft; the lower end of the transmission shaft extends into the discharging outlet. By means of the scheme, the motor, the transmission shaft, the screen and the anti-blocking paddle can effectively prevent metallurgical auxiliary materials from being blocked, caking, forming a hole and the like in the discharging device, continuous and even discharging of the metallurgical auxiliary materials can be ensured, and the harmful effects on the quality and productivity of metallurgical auxiliary material balling due to uneven and untimely discharging are eliminated.

Description

technical field [0001] The invention relates to the field of metallurgy, in particular to a screening type anti-blocking feeder for metallurgical auxiliary materials. Background technique [0002] As an auxiliary product in steelmaking, metallurgical auxiliary materials are indispensable additives in the steelmaking process of the metallurgical industry, which have a greater impact on the final smelting effect. At different stages of the ironmaking and steelmaking production process, different metallurgical auxiliary materials need to be added to ensure the smelting effect. Before the metallurgical auxiliary materials are used in the furnace, they usually need to be pressed into balls with a ball press machine, so as to facilitate smelting and calcination in the furnace. [0003] In the prior art, usually the powder for metallurgical auxiliary materials is proportioned according to the requirements, then enters the feeder through the feeder inlet of the feeder, and uses the...

Problems solved by technology

However, in the process of storing the materials after proportioning, there will often be a small amount of lumps. After the materials enter the feeder, the lumpy materials will easily form a "bridge" phenomenon at the discharge port and block the discharge port.

Moreover, due to the poor fluidity of the powdery material, there is friction between the materials, which can easily cause the materials to block each other, forming a lower "cavity" inside the material, and the upper material cannot go down, resulting in uneven and untimely feeding.
