Abstract
The utility model discloses a kind of fine reduction furnace banking fire mechanisms, include furnace body and material conveying mechanism, the front end of furnace body is equipped with feed inlet, material conveying mechanism extends to the inside of furnace body across feed inlet, the front end of furnace body is installed with fireguard on front side of feed inlet, and gap is respectively provided between the upper and lower end of fireguard and the upper edge of feed inlet and the upper surface of material conveying mechanism.The utility model is simple in structure, in the feed inlet of fine reduction furnace（That is the entrance of burner and hydrogen）Fireguard is increased, has disperseed gas flow, and gas has first carried out transmission of heat by contact before reduction reaction occurs with iron powder with baffle, gas flowing heat transfer rate is accelerated, so that the radiant heat energy in fine reduction furnace is fully utilized, greatly reduce energy consumption.
Description
Technical field
The utility model is related to the fine reduction furnace field for Powder Metallurgy Industry, specifically a kind of fine reduction furnace banking fire machine
Structure.
Background technology
Fine reduction furnace is common one of the equipment of Powder Metallurgy Industry, the feed inlet of existing fine reduction furnace（That is burner, and
Air inlet）Usually opened type structure, the burner due to hydrogen gas nozzle from fine reduction furnace have a certain distance, are blown into hydrogen
When, air velocity cannot control, and cannot efficiently use the radiation energy in furnace body, and heat is unevenly distributed, and can lead to smart reduction
Heat utilization rate in stove reduces, therefore when the iron powder of reduction phase homogenous quantities, and the consumption of hydrogen increases, and wastes the energy.
Utility model content
The purpose of this utility model provides a kind of fine reduction furnace banking fire mechanism, in the feed inlet of fine reduction furnace（That is burner,
It is the entrance of hydrogen）Increase fireguard, can effectively stop air-flow, reduce the consumption of hydrogen, it is energy-saving to achieve the purpose that.
The technical solution of the utility model is as follows：
A kind of fine reduction furnace banking fire mechanism, includes furnace body and material conveying mechanism, and the front end of the furnace body is equipped with charging
Mouthful, the material conveying mechanism extends to the inside of the furnace body across the feed inlet, it is characterised in that：The furnace body
Front end is installed with fireguard, the upper edge of the upper and lower end of the fireguard and the feed inlet on front side of the feed inlet
It is respectively provided with gap between the upper surface of the material conveying mechanism.
The fine reduction furnace banking fire mechanism, it is characterised in that：In the charging in the rack of the material conveying mechanism
The front of mouth is rotatablely equipped with pressure roller.
The fine reduction furnace banking fire mechanism, it is characterised in that：The width of the fireguard is slightly larger than the feed inlet
Width.
The beneficial effects of the utility model：
The utility model is simple in structure, in the feed inlet of fine reduction furnace（That is the entrance of burner and hydrogen）Increase gear
Fiery plate has disperseed gas flow, and gas has first carried out transmission of heat by contact with baffle, added before reduction reaction occurs with iron powder
Fast gas flows heat transfer rate, so that the radiant heat energy in fine reduction furnace is fully utilized, greatly reduces energy consumption.
Description of the drawings
FIG. 1 is a schematic structural view of the utility model.
Specific implementation mode
