A powder dust removal and iron removal device

Abstract

The invention discloses a dust-iron removing device for powder which comprises a pulverizer, a dust remover, a cone-shaped buffer device, an electric magnetic iron remover and a semi-finished product trough, wherein the dust remover comprises filter cylinders and a dust remover box body; an air blower is arranged on the outer side of the dust remover box body; the filter cylinders are fixedly mounted at the inner part of the dust remover box body; a bracket is arranged at the lower part of the dust remover; the cone-shaped buffer device is arranged in the bracket; a discharging valve is arranged at the lower part of the cone-shaped buffer device; the electric magnetic iron remover is positioned at the lower part of the discharging valve; and a powdering passage and an iron discharging passage are arranged at the upper part of the semi-finished product trough. The dust-iron removing device for powder can remove dust, can also slow down the impulsive force during the feeding process, and can remove iron for the powder; the dust remover and the electric magnetic iron remover are in the same powdering passage; no other side road exists; all powder passes through the electric magnetic iron remover to remove iron after passing through the dust remover; the iron content of the powder is reduced; the quality of the product is improved; the fault point of the whole device is reduced; and the energy consumption is reduced.

Description

technical field [0001] The invention relates to the field of powder processing, in particular to a powder dust and iron removal device. Background technique [0002] Most of the powder is fine granular material. When the powder crushed by the pulverizer is transported to the powder silo, the fine powder output from the outlet of the pulverizer is light in weight and not easy to feed. The dust in the air is easy to float into the surrounding air, forming suspended particles, and the flying of dust is extremely serious, causing air pollution. The powder falls freely to the powder silo. Due to the height drop, the impact force is large, and the discharge is not smooth, which affects the quality of the entire product. In addition, the current powder dust collector and iron remover are divided into two parallel branches. In this way, the fine powder in the branch of the dust collector enters the semi-finished product trough without the electromagnetic iron remover, and the final...

AI Technical Summary

Problems solved by technology

[0002] Most of the powder is fine granular material. When the powder crushed by the pulverizer is transported to the powder silo, the fine powder output from the outlet of the pulverizer is light in weight and not easy to feed. Medium-sized dust is easy to float into the surrounding air, forming suspended particles, and the flying of dust is extremely serious, causing air pollution

The powder falls freely to the powder silo. Due to the height drop, the impact force is large, and the discharge is not smooth, which affects the quality of the entire product.

In addition, the current powder dust collector and iron remover are divided into two parallel branches. In this way, the fine powder in the branch of the dust collector enters the semi-finished product trough without the electromagnetic iron remover, and the final product has high iron content and high product quality. Low, and the energy consumption of the dust collector is large

At the same time, since there are two branches of the dust collector and the iron remover, two unloading valves need to be used, which increases the energy consumption, more branches, and more fault points.
