The hearth electrode of arc has air-cooled contact pin type, conducting hearth formula, three kinds of forms of water cooling bar type, wherein air-cooled contact pin type and conducting hearth formula
Air blast cooling is carried out using big flow axial flow blower, hearth electrode cooling surface is larger；Water cooling bar type bottom electrode structural is compact, but needs
Water cooling is wanted, the potential safety hazard that there is the blast of furnace bottom bleed-out.
The content of the invention
The purpose of this utility model is to provide a kind of cylinder type air cooled bottom electrode, overcomes defect present in prior art.
The technical scheme that the utility model is used for：
A kind of cylinder type air cooled bottom electrode, it is characterised in that：
Including hearth electrode body, hearth electrode body is conductive drum, conductive plate and cooling chamber from top to bottom.
Cooling chamber is connected with air duct, and air duct end is provided with high pressure whirlpool blower fan, air duct and is connected with

Conductive drum is uniformly provided with multiple holes to be made up of the steel cylinder of single steel cylinder or multiple concentric circles on steel cylinder.
Multiple thermometrics for monitoring hearth electrode cooling effect in real time are evenly equipped with conductive plate and at the steam vent of cooling chamber
Thermocouple.
The measuring instrumentss of the pressure, flow, temperature parameter for measuring pressure-air are provided with air duct.
The utility model has advantages below：
The utility model by hearth electrode body design into top conductive drum, middle part conductive plate, the part of bottom cooling chamber three,
Three parts are welded together using ordinary carbon steel material, the thickness of conductive tube and conductive soleplate inside and outside reasonable selection, it is ensured that bottom
The requirement of electrode current-carrying capacity；The pressure-air with water smoke is blasted to cooling chamber using high pressure whirlpool blower fan, cooling size is less
Conductive soleplate, by heat transfer, further cools down the conductive drum on but top, so as to realize effective cooling to hearth electrode.Should

Embodiment
The utility model is described in detail with reference to embodiment.
A kind of cylinder type air cooled bottom electrode that the utility model is related to, is mainly used in the electric arc heated using direct-current arc
Stove, molten point of stove etc., including hearth electrode body, hearth electrode body is conductive drum 5, conductive plate 6 and cooling chamber 7 from top to bottom.It is cold
But room 7 is connected with air duct 2, and the end of air duct 2 is provided with high pressure whirlpool blower fan 1, air duct 2 and is connected with water smoke pipe
Road 3.Conductive drum 5 is uniformly provided with multiple holes to be made up of the steel cylinder of single steel cylinder or multiple concentric circles on steel cylinder.Rationally choosing
Select the wall thickness of steel cylinder, it is ensured that cylinder pass through the requirement of the current-carrying capacity of electric current.The one side of cooling chamber 7 plays jointed anode bus
With the effect of conduction electric current, on the other hand external high pressure cold air is guided on conductive plate 6, it is cooled down.
Multiple surveys for monitoring hearth electrode cooling effect in real time are evenly equipped with conductive plate 6 and at the steam vent of cooling chamber 7
Warm galvanic couple 8.The measuring instrumentss 4 of the pressure, flow, temperature parameter for measuring pressure-air are provided with air duct 2.
High pressure whirlpool blower fan 1 produces big-flow high-pressure air, and by the water smoke pipeline 3 being connected with air duct 2, high pressure is empty
Gas is mixed into water smoke, and is blown into the cooling chamber 7 of hearth electrode body.Pressure-air with water smoke is in the inside wind distributing disc of cooling chamber 7
In the presence of be blown on conductive plate 6, conductive plate 6 is cooled off, and the hot-air after cooling is through the exhaust on circumference in cooling chamber 7
Diffuse in hole.By welding, conductive plate 6 links together conductive drum 5 and cooling chamber 7, what conductive plate 6 was cooled down by pressure-air
Meanwhile, by heat transfer, the conductive drum 5 for being subjected to furnace high-temperature is also cooled down, and then realizes the cooling of hearth electrode system.
Content of the present utility model is not limited to cited by embodiment, and those of ordinary skill in the art are new by reading this practicality
Type specification and any equivalent conversion taken technical solutions of the utility model, are claim institute of the present utility model
Cover.
