In order to achieve the above object, electric heat treating furnace at the bottom of the designed steel pipe energy-saving formula roller of the utility model, it comprises body of heater and is arranged side by side the furnace roller in body of heater lower end, in the upper end of body of heater inside and the lower end of the furnace roller of body of heater inside be all disposed with nichrome wire, at body of heater, with respect to the front end of furnace roller direction of motion, be provided with heat recovery chamber, lower end in heat recovery chamber is provided with furnace roller equally, the height of the furnace roller in heat recovery chamber is less than or equal to the height of the furnace roller in body of heater, at body of heater, with respect to the rear end of furnace roller direction of motion, be provided with preheating chamber, lower end at preheating chamber is provided with furnace roller equally, the height of the furnace roller in preheating chamber is greater than or equal to the height of the furnace roller in body of heater, in heat recovery chamber, be provided with blast pipe, blast pipe is put in heat recovery chamber's inner disk winding, and is connected to preheating chamber inside by pipe connecting, and the port of the pipe connecting in preheating chamber is provided with air outlet.
Technique scheme heats by nichrome wire in body of heater, and heating power more strengthens, and device structure is simplified more, simultaneously and environmental protection more, can not produce the material to environment such as waste gas, simultaneously accurate to heating and temperature control; The setting of heat recovery chamber and preheating chamber simultaneously, heat on steel pipe can be passed to the air in blast pipe in heat recovery chamber, by pipe connecting, warm air is delivered in preheating chamber and before body of heater, just now carries out preheating to entering again, make its temperature can be preheated to 300-400 ℃, thereby reduced the temperature head heating in body of heater, reduced greatly the energy that steel pipe is processed required consumption, energy conservation is obvious, and can shorten heat-up time, improve process for processing efficiency.
As optimization, in the upper end of body of heater inside and the lower end of the furnace roller of body of heater inside be interval with support bar, support bar is identical with furnace roller direction, described nichrome wire winding is on support bar.This structure can make nichrome wire fixing more firm in body of heater, improves its use properties.
As optimization, in the gap of the support bar of the furnace roller below in described body of heater between adjacent two furnace rollers.The circulation transmission of the convenient stove intimate heat of this structure, avoids furnace roller nichrome wire is blocked and cause the heat on nichrome wire to transmit.
Between described heat recovery chamber and body of heater, laminating arranges, and between preheating chamber and body of heater, laminating arranges, and on the port being connected between heat recovery chamber and body of heater and between preheating chamber and body of heater, is provided with the door that can freely swing, and the height of the lower surface of door is higher than the height of furnace roller.The setting of this structure, make whole structure compacter, and can intercept the circulation of the air between body of heater and heat recovery chamber and preheating chamber, avoid by a large amount of freezing airs, being entered in body of heater in conveying steel pipe process, a large amount of warm airs flow out in body of heater, affect heating efficiency, therefore this structure can effectively reduce the loss of energy, improve energy utilization rate, door can freely swing simultaneously, to the conveying of the steel pipe of different diameter, can not impact.
Described air outlet is arranged in the preheating chamber near body of heater one end, and the direction of air outlet is for charging place towards preheating chamber and be tilted to down.The setting of this structure, what make hot blast blows to aligning steel pipe, and from inside to outside, makes the hottest wind on the steel pipe of the most close body of heater, thus the temperature when being conducive to improve steel pipe and entering body of heater improves the use properties of equipment, save energy.
Electric heat treating furnace at the bottom of the resulting steel pipe energy-saving of the utility model formula roller, it adopts electric-heating-wire-heating, can reduce exhaust emission, heat on the steel pipe that simultaneously thermal treatment can be completed fully reclaims, for to entering the preheating of the steel pipe before body of heater, successful, it is poor to the Heating temperature of steel pipe to greatly reduce in body of heater, reduce energy consumption, cost-saving, increase economic efficiency.
On existing equipment, while adopting coal or Sweet natural gas, as raw material, steel pipe is heated to 1100 ℃, it is 500-600 unit that average steel pipe per ton needs cost; And on this equipment, use after electrically heated and heat recuperation, steel pipe per ton is heated to 1100 ℃, required cost is on average between 100-200 unit.
