Background technology
In ore dressing processing industry, need a large amount of abrasion-proof steel balls, one of master operation of abrasion-proof steel ball processing is timeliness thermal treatment.Prior art is to adopt car type furnace to realize the timeliness thermal treatment of abrasion-proof steel ball.After steel ball quenching water outlet, proceed in material frame, manually with driving, the material frame of filling steel ball is hung on to car type furnace furnace bottom, push in car type furnace, closed furnace door, by electrically heated ageing treatment; Control for Kiln Temperature at 260 ℃ after a few hours process, blowing out, blow-on, and material frame is hung out together.Adopt existing this chassis aging oven to have a lot of shortcomings, for example: whole process all needs artificial long-term stay-at-home operation; Heating equipment is set separately, consumes the energy; Distributing mode limitation is large, and stockpile internal and external temperature is inhomogeneous, causes unstable product quality; Batch production, causes the heating and cooling cycle to grow, yield poorly, equipment life is short; After discharging, do not weigh and cannot realize automatization with packaging facilities.
Summary of the invention
Object of the present invention is exactly the ageing treatment mode complex operation that will overcome existing abrasion-proof steel ball, and production efficiency is low, and energy consumption is large, unstable product quality, and the problem such as equipment life is short, provides a kind of for the heat treated track type aging oven of abrasion-proof steel ball.
Concrete scheme of the present invention is: a kind of for the heat treated track type aging oven of abrasion-proof steel ball, include hotblast stove and cool wind stove, two stoves are a word arranges, and it is characterized in that: track type conveyor chain is all housed in two stoves, two conveyor chains dock mutually, at the furnace roof of cool wind stove, some cold blast engines are housed; The some groups of heating ducts of arranging to equidistant intervals along long are housed at the furnace roof of hotblast stove, every group of heating duct is communicated with heat supply supervisor by an arm, heat supply supervisor is by the external process furnace of induced draft fan, and fork-join has an aid distributing pipe on every arm, all aid distributing pipes connect cold wind supervisor, cold wind supervisor is outer is furnished with gas blower, and at the two-port place of hotblast stove, front and rear row fan housing is installed, and two exhaust hoods connect outer smoke evacuation chimney by exhaust duct.
In the present invention, near every group of heating duct, a stirring blower fan is installed in air heating furnace roof portion, stirs the main shaft of blower fan and put in agitating vane is installed in stove.
Described in the present invention, every group of heating duct includes two airducts, and two airducts are arranged near the two side in hotblast stove respectively.
In the present invention, in the bottom of hotblast stove, some recovery tube are installed and collect connection induced draft fan by return main.
In the present invention, on every arm and each air distribution pipeline, regulated valve is installed.
A weighing device is equipped with in exit end docking at hotblast stove track type conveyor chain in the present invention.
In the present invention, in hotblast stove, be fitted with thermopair, external computer control system realizes temperature detection, control.
Principle of work of the present invention is: lift rises to stokehold by abrasion-proof steel ball and transmits crawler belt from the cylinder that quenches, first entering cool wind stove is cooled to steel ball below 70 ℃, be provided with axial cooling air machine straight but steel ball of blast-cold downwards at this section of top, then stokehold crawler belt is sent to steel ball on hotblast stove crawler belt, and enter thereupon and in hotblast stove, carry out timeliness thermal treatment, hotblast stove does not arrange combustion unit, realize but utilize the hot flue gas of process furnace and air proportioning to introduce in stove, (be responsible for by induced draft fan suction heat supply by the hot flue gas of process furnace, blast cold wind with gas blower simultaneously, mix by suitable proportion with the hot blast of each hot blast manifold, obtain the temperature required mixture heat gas of technique), pass in hearth of hot-blast stove by furnace roof heating duct again, steel ball is heated and is incubated, air heating furnace roof is provided with and stirs blower fan and thermopair, stir blower fan and strengthen the recycle system velocity of flow of hot blast in burner hearth, thermopair is measured the temperature of hot gas flow in stove in real time, and by computer control system collect and feedback signal to the performer on each region hot blast manifold and cold wind arm, realize automatically and regulating, stablize furnace temperature, the each temperature control of hotblast stove region bottom arranges hot air reflux pipeline, is connected in parallel on return main road, mixes with the hot flue gas of process furnace, enters high temperature draught fan, enters in stove after mixing cold wind, carries out waste heat recovery, reduces energy consumption, in stove, hot gas is extracted out by the exhaust hood at hotblast stove two ends, guarantee hotblast stove internal pressure stabilises, when the discharging of stove tail, steel ball falls into weighing unit, on weighing unit, place in advance packing bag, while arriving predetermined weight, hang away weighing device automatic clear, computer automatic control system record accumulative total gross weight by finished product packing.
The present invention adopts track type body of heater, and steel ball end inlet side goes out, and has realized continous way production, and output is large, and production efficiency is high, and in stove, temperature is evenly controlled, constant product quality, and energy consumption is low, and service life of equipment is long.
