Abstract

The utility model discloses a special dust remover of an electric furnace carbon spraying device, which relates to the technical field of dust removing equipment and comprises a box body with an open bottom, wherein the bottom of the box body is arranged at the top of a storage bin through a flange, and an inner cavity of the box body is communicated with the inner cavity of the storage bin; a fan communicated with the upper chamber is arranged outside the box body, and a nitrogen pipe controlled by a pulse electromagnetic valve is also communicated in the upper chamber. The utility model discloses guaranteed that the unloading is unobstructed when the carbon dust adds, effectively solved the raise dust and the collection problem of dust.

Description

Special dust remover for carbon spraying device of electric furnace

Technical Field

The utility model relates to a dust collecting equipment technical field especially relates to a special dust remover of carbon device is spouted to electric stove.

Background

In the electric furnace smelting process, in order to increase the carbon content in the molten steel, a smelting plant generally adopts a carbon spraying device to add carbon into the electric furnace. Generally, the carbon spraying device is mainly used for adding carbon powder into a storage bin above an electric furnace, then the carbon powder is sprayed into the electric furnace by utilizing negative pressure, the existing storage bin is generally in an exposed state, and bagged carbon powder is poured into a charging hopper at the top of the storage bin through a travelling crane and then enters the storage bin.

This design has the following disadvantages:

1. generate great dust during charging, cause great pollution to surrounding working areas and do not meet the environmental protection standard.

2. During charging, the dust is raised, so that the carbon powder is lost.

3. Unsmooth feeding causes difficult blanking.

4. The dust seriously damages the components of the equipment.

5. The carbon powder falls freely due to the overall open state, which causes unsmooth feeding.

Disclosure of Invention

An object of the utility model is to overcome the not enough of above-mentioned technique, provide a special dust remover of carbon device is spouted to electric stove, solve the raise dust problem that produces when the storage silo adds the carbon dust, can effectively collect the dust, make the carbon dust unloading unobstructed.

The utility model adopts the technical proposal that: a special dust remover for a carbon spraying device of an electric furnace comprises a box body with an opening at the bottom, wherein the bottom of the box body is arranged at the top of a storage bin through a flange, and an inner cavity of the box body is communicated with the inner cavity of the storage bin; a fan communicated with the upper chamber is arranged outside the box body, and a nitrogen pipe controlled by a pulse electromagnetic valve is also communicated in the upper chamber.

In the loading hopper at storage silo top was poured into to the carbon dust in bags, fan work, outside convulsions, made the air current take out to the dust remover in from the storage silo to form the negative pressure in the storage silo, make the carbon dust unloading faster, and the dust is difficult for outwards spilling over. The filter cartridge in the dust collector has air permeability, dust is attached to the outer surface of the filter cartridge, and air is drawn out of the fan through the filter cartridge. And after the feeding is finished, the fan is closed, and then the pulse electromagnetic valve is opened to enable the nitrogen to uninterruptedly spray the filter cylinder, so that the ash on the outer surface of the filter cylinder falls into the storage bin.

Further, the number of the filter cartridges is 4.

Furthermore, two access doors are further arranged at the top of the box body, so that the maintenance and the overhaul are convenient.

The utility model has the advantages that: the device ensures smooth feeding when carbon powder is added, solves the problems of dust raising and collection, purifies the working area, protects the equipment components and parts, and radically cures the environmental pollution of the equipment.
