Description
Technical field
The utility model relates to conveyer, especially a kind of continuously pre-heating conveyer of waste steel for electric furnace smelting.
Background technique
Currently, the feed way used when waste steel for electric furnace smelting, big mostly use expect that basket charging or disresonance type steel scrap are continuous
Conveyer charging is preheated, the material of addition is mostly the waste material of cold burden or preheating temperature not high (only 300-400 °), primary to be added greatly
Cold burden or the not high waste material of preheating temperature are measured, the duration of heat is long, and production efficiency is low, and the performance of enterprises is poor.
Summary of the invention
It is high that the purpose of the utility model is to provide a kind of charging preheating temperatures, can effectively improve production efficiency, increases economical
The waste steel for electric furnace continuously pre-heating conveyer of benefit.
The technical solution of the utility model is completed as follows, it includes a disresonance type steel scrap continuously pre-heating
Conveyer, it is characterised in that: be to be equipped with a reciprocating vibration excitor in the rear end of delivery chute, vibration excitor and delivery chute are hung
On support base, feeding section is reserved in delivery chute rear end, insulation cover is installed in top, water-cooling cover is installed before insulation cover,
Uniformly distributed heating burner and flue-gas temperature detection device are installed in insulation cover two sides or top into delivery chute, in exhanst gas outlet
Before combustion air heat exchanger is installed, water cooled seal system is installed between insulation cover and delivery chute, behind each burner point
Not She You flame detecting device and pressure transmitter, mobile transport trolley is installed between delivery chute and electric furnace, in delivery chute
Material pressing device and dynamic sealing means are installed at upper feed opening.Platform and ladder are equipped on the delivery chute of insulation cover two sides.
The utility model is greatly improved the preheating temperature of scrap smelting, the work for energy efficiency of shortening the heat, play
With.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
Embodiment is described in detail in conjunction with attached drawing, it includes a disresonance type steel scrap continuously pre-heating conveyer, main to improve
Place is to be equipped with a reciprocating vibration excitor 1 in the rear end of delivery chute 2, and vibration excitor and delivery chute are suspended on support base 3,
Feeding section is reserved in delivery chute rear end, insulation cover 6 is installed in top, water-cooling cover 7 is installed before insulation cover, in insulation cover
Two sides or top are equipped with uniformly distributed heating burner 8 and flue-gas temperature detection device 9 into delivery chute, pacify before exhanst gas outlet 16
Equipped with combustion air heat exchanger 10, water cooled seal system 11 is installed between insulation cover and delivery chute, divides behind each burner
Not She You flame detecting device 12 and pressure transmitter 13, mobile transport trolley 5 is installed between delivery chute and electric furnace 4,
Material pressing device 15 and dynamic sealing means 14 are installed at feed opening on delivery chute.
Platform and ladder are equipped on the delivery chute of insulation cover two sides.
The utility model does reciprocal horizontal anharmonic by the reciprocal vibration excitor driving delivery chute of tail portion when work through above-mentioned improvement
Raw scrap material is sent into insulation cover the preheating section conveying for being evenly equipped with heating burner by vibration through material pressing device and dynamic sealing means
In slot, fuel value is can be improved after preheating by heat exchanger in the coal gas and combustion air of each burner combustion, is played energy-saving effect, is being protected
Water cooled seal system is set between temperature cover and preheating section delivery chute, it is ensured that flue gas is not excessive, and flame is arranged behind burner and examines
Device and pressure transmitter are surveyed, can detecte the size of flame；Dynamic sealing means and material pressing device are set at material inlet,
Certifiable cool exterior air does not enter in insulation cover and delivery chute, and the material of high blow tank is forced down convenient for conveying；In addition exist
Platform and ladder are set on the delivery chute on insulation cover both sides, maintenance can be facilitated.The utility model can make to enter the original before electric furnace
The coal gas that material preheating temperature reaches 700-800 °, and burnt is mostly the coal gas generated in enterprise production process, has section
The benefit of energy emission reduction, shortens smelting cycle, improves production efficiency and economic benefit.
