The scheme of the technical problem that the utility model solves is: the air force stove fast cooling device that is adopted; Comprise body of heater and power set; Deflector, deflector are set in body of heater to be arranged in parallel with body of heater roof, right side wall, left side wall and rear wall respectively; On the gap of deflector and tweer constitutes, left and right, after the wall chamber passage that communicates, deflector also communicates with the body of heater inner chamber in the front portion of body of heater, the rear portion communicates with inner chamber through impeller; Power set are made up of variable-frequency motor and impeller; Its special feature is: offer the inlet scoop at the body of heater roof to the middle section position between the fire door; Offer exhaust outlet in body of heater roof rear end near the position of impeller; Device is controlled air draft air door mechanism, the air draught air door mechanism that two air ports open and close respectively on exhaust outlet and inlet scoop, and described air draft air door mechanism, air draught air door mechanism are made up of cylinder, valve casing and valve plate, and valve plate top is insulation material.
Said exhaust outlet and inlet scoop make air draught and air draft not at same confined space through pipeline isolation.
The principle of the utility model: the fast cooling scheme of employing and the heating principle of air force stove adapt.Cooling method is opened the inlet scoop for the cooling of self-priming self arrangement in stage casing, body of heater top, introduces fresh cold air; Offer exhaust outlet at the impeller cavity top, discharge hot-air.Form scavenge duct, reach the purpose of cooling.This scavenging period is followed in mobile the carrying out of inner furnace temperature control gas circulation, reaches the cycle down temp effect.The air draft air door mechanism is set and the air draught air door mechanism is controlled at the air port opening and closing, air door mechanism is closed two air ports when body of heater will heat; Air door mechanism is opened two air ports when body of heater is lowered the temperature.Reduce the pneumatics blower system through this programme, and the cooling ability is significantly improved, improved the temperature field uniformity in the temperature-fall period simultaneously.
The beneficial effect of the utility model is:
Adopt the heating principle of fast cooling scheme and air force stove to adapt; Due to the resulting from of air force stove heat energy changed based on impeller, furnace wall and windage heating and air flow stream speed, pressure, because the circulating of air, heating in stove and hot air circulation were carried out simultaneously; Help realizing the high homogeneity in temperature field in the body of heater; Can omit simultaneously heating element heaters such as electrothermal tube, reduce the parts that keep warm field uniformity, significantly reduce localized hyperthermia's point, body of heater thermal capacitance and body of heater heat bridge; Thereby reduced energy consumption, reached energy-saving effect.The fast cooling method is under the situation of not extra increase power set; Through on body of heater, increasing exhaust outlet and inlet scoop, make the heating cooling of air force stove accomplish by power set, its structure is significantly simplified; It is integrated to reach the heating cooling, reaches the effect of forced cooling.Realize dispersion through the circulated air of air force stove simultaneously, the uniformity of temperature field when reaching cooling to cryogenic gas.(the temperature field uniformity is ± 3).

The specific embodiment
Below in conjunction with above-mentioned accompanying drawing, the enforcement of the utility model is elaborated.
As shown in Figure 1, the general structure of the utility model comprises body of heater 6 and power set 1.Establish deflector 7 in the body of heater 6, deflector 7 is arranged in parallel with inboard wall of furnace body respectively, on the gap of deflector and tweer constitutes, left and right, after the wall chamber passage that communicates, and communicate with the body of heater inner chamber in the front portion of body of heater.Power set are made up of variable-frequency motor 1 and impeller 4, and under power set drove, high-speed air circulated in furnace body wall chamber passage and body of heater inner chamber, accomplish wind energy to heat energy conversion, constitute the body of heater with the air force heating.
In the application of air force stove utilization rate or some the special process requirement that improves the air force stove; Need carry out fast cooling to body of heater; The utility model has designed the fast cooling device for the air force heating furnace; Offer inlet scoop 8A at the middle section position of body of heater roof, offer exhaust outlet 8B near the position of impeller 4, device cooling air door mechanism 3 and 5 controls, two air ports keying respectively on exhaust outlet and inlet scoop in body of heater roof rear end.The air duct 2 of air draft air door mechanism 3 communicates with fresh cold air.Cooling air door mechanism 3 and 5 is made up of cylinder 9, valve casing 10 and valve plate 11, on valve plate 11 tops the insulation material (see figure 2) is housed.Air draft air door mechanism 3, air draught air door mechanism 5 are closed two air ports when body of heater heats; Air draft air door mechanism 3, air draught air door mechanism 5 are opened two air ports when body of heater is lowered the temperature.
