Beneficial effect of the present invention is mainly reflected in: PLC control system control roll bar type is carried, and is safe and reliable; Good airproof performance in the stove can add protective gas in stove, prevent the oxidation of surface of the work in the stove, thereby saves the workpiece raw material.
Description of drawings
The invention will be further described below in conjunction with accompanying drawing:
Fig. 1 is the schematic diagram of specific embodiments of the invention.
Fig. 2 is the vertical view of Fig. 1.
The specific embodiment
Following with reference to the description of drawings specific embodiments of the invention.
See figures.1.and.2, a kind of energy-conservation stove of two-way recovery type heat continuous isothermal heat treatment up and down of the specific embodiment of the invention comprises body of heater, and double-deck combustion flue 1,2 up and down is set in the body of heater, and every layer of combustion flue sets gradually 6 meters long preheating sections 3,31; Length is 9 meters bringing-up section 4,41; Length is 6 meters cooling section 5,51.The parallel reverse setting of upper and lower layer combustion flue wherein is provided with heat exchange mechanism between the cooling section of the preheating section of one deck and another layer in the upper and lower layer combustion flue, in the upper and lower layer of combustion flue conveying roller rod 7 is set.
Described bringing-up section comprises the thermal treatment zone 8, fast cold-zone 9, isothermal region 10 successively.Closed thermal cycle passage is set between the fast cold-zone of cooling section and bringing-up section.Closed thermal cycle passage comprises cooling air channel, and the pump 12 of the cold wind of cooling section being sent into fast cold-zone is set on the cooling air channel, and cooling air channel passes through fast cold-zone, and communicates with the warm-air pipe 1 that leads to cooling section.The combustion flue inwall is lined with the microwell plate heat insulation layer.Described heat exchange mechanism comprises hot switching path 6, and hot switching path is provided with thermal circulation fan.
In the described upper and lower layer combustion flue separately roller rod transmitting device drive by 11 controls of independent PLC control system and by chain sprocket.Such levels is controlled separately and can be made the stove internal efficiency better, and more energy-conservation, thereby strengthens output.
In addition, the setting of roller rod makes the better tightness of the fire door in the combustion flue, because the roller rod is little more a lot of than the gap of transport tape and fire door with the gap of fire door.Can prevent the loss of heat so well.And the roller rod can make the turnover stove of material speed up, and realizes fast charging and fast discharging, increases work efficiency.
