The utility model content
The purpose of this utility model is to overcome the deficiency that prior art exists, and a kind of carbon restoration recovery type heat continuous isothermal spheroidizing annealing furnace that can fully reclaim heat energy is provided.
The purpose of this utility model is achieved through the following technical solutions:
Heat recovery-type carbon restoration continuous isothermy spheroidizing annealing furnace, comprise body of heater and the fire door that is arranged at the body of heater both sides, characteristics are: be provided with the carbon restoration section in the described body of heater, the rear end of described carbon restoration section is disposed with heating zone, fast cold section, isothermal section and slow cooling section, the side of described slow cooling section is connected preheating section, preheating section parallels with the slow cooling section, and is provided with the thermal cycling passage between preheating section and slow cooling section, on the thermal cycling passage heat-exchange fan is installed.
Further, above-mentioned heat recovery-type carbon restoration continuous isothermy spheroidizing annealing furnace wherein, is provided with the transport sector that is used to carry the guide rail of hopper motion and is used to drive the hopper motion in the described body of heater.
Further, above-mentioned heat recovery-type carbon restoration continuous isothermy spheroidizing annealing furnace, wherein, the length of described carbon restoration section is 1.5 meters, and the length of heating zone is 3 meters, and fast cold section length is 1.5 meters, and the length of isothermal section is 3 meters, the length of slow cooling section is 6 meters.
Again further, above-mentioned heat recovery-type carbon restoration continuous isothermy spheroidizing annealing furnace wherein, is provided with e Foerderanlage in the described thermal cycling passage.
The substantive distinguishing features of technical solutions of the utility model and progressive being mainly reflected in:
The utility model is rational in infrastructure, both can utilize carbon restoration to improve the quality of products, and can make full use of high temperature workpiece waste heat again and make preheating usefulness for the workpiece that newly advances stove, the thermo-efficiency height, floor space is little, and is high-quality and efficient, energy-conserving and environment-protective.
Description of drawings
Below in conjunction with accompanying drawing technical solutions of the utility model are described further:

Fig. 2: schematic top plan view of the present utility model;
The B-B cross-sectional schematic of Fig. 3: Fig. 2.
The implication of each Reference numeral sees the following form among the figure:
Embodiment
As shown in Figure 1 and Figure 2, heat recovery-type carbon restoration continuous isothermy spheroidizing annealing furnace, comprise body of heater 1 and the fire door 11 that is arranged at the body of heater both sides, be provided with the transport sector 8 that is used to carry the guide rail 12 of hopper motion and is used to drive the hopper motion in the body of heater, and be provided with the push rod that the promotion hopper moves on guide rail at the body of heater two ends; Be provided with carbon restoration section 2 in the body of heater, the rear end of carbon restoration section 2 is disposed with heating zone 3, fast cold section 4, isothermal section 5 and slow cooling section 6 (heat exchange zone), the length of carbon restoration section 2 is 1.5 meters, the length of heating zone 3 is 3 meters, fast cold section 4 length is 1.5 meters, the length of isothermal section 5 is 3 meters, and the length of slow cooling section 6 is 6 meters; The side of slow cooling section 6 is connected preheating section 7, as shown in Figure 3, preheating section 7 parallels with slow cooling section 6, and is provided with thermal cycling passage 9 between preheating section 7 and slow cooling section 6, heat-exchange fan 10 is installed on the thermal cycling passage 9, is provided with e Foerderanlage in the thermal cycling passage 9.
Side design in the slow cooling section has workpiece preheating combustion flue, promotes hopper preheating one by one by push rod, and preheating finishes the back by the correspondence position that transport sector makes it to enter feeding port is set in the body of heater.
Normal course of operation is as follows: imported into to heating zone 3 heating of annealing by transport sector 8 after carbon restoration section 2 is carried out carbon restorations when newly advancing workpiece.The experience heating insulation afterwards forward of the workpiece of the indoor new dish of then packing into of carbon restoration, workpiece pulsation.Fast cold section 4 enters isothermal section 5 nodularizations after fast cold, comes out of the stove via slow cooling section 6 (heat exchange zone) at last.Go into workpiece and the operation of aforementioned reverse direction with stylish, realize the waste heat heat production, reach temperature about 400 ℃, switch charging and can enter the carbon restoration chamber via carrying through heat exchange zone.Absorbed by when cooling off, putting into furnaceman's part, so the heat energy utilization rate of equipment greatly improves through the waste heat of high temperature workpiece.
In sum, the utility model is rational in infrastructure, can realize carbon restoration, and can make full use of annealing high temperature workpiece waste heat and make preheating usefulness for the workpiece that newly advances stove, the thermo-efficiency height, and the space availability ratio height, floor space is little, and is high-quality and efficient, energy-conserving and environment-protective.
What need understand is: the above only is a preferred implementation of the present utility model; for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
