Referring first to Fig. 1 to Fig. 2, what Fig. 1 to Fig. 2 was disclosed is the first embodiment of waste-heat recovery device, Yi Zhongyu
Heat reclamation device, including the oven 1 equipped with two air inlets 11 and two air outlets 12, the first exhausting for being arranged on outside oven 1
Machine 21, be arranged on the heater 3 after the first exhaust fan 21 and the insufflation unit 4 being arranged in the oven 1, two inlet airs
Mouth 11 is respectively the first air inlet 111 and the second air inlet 112, and two air outlets 12 are respectively the first air outlet 121 and second
Air outlet 122, first exhaust fan 21, heater 3 and oven 1 connect into a circulation loop by pipeline 5, this practicality is new
In type, the second exhaust fan 22 and waste heat recovery part 6 being arranged at the second air outlet 122 on pipeline 5 are further included, the waste heat returns
Addressee 6 is the metal frame that a both ends communicate, specifically, both ends, which communicate, refers to that both ends are penetrating, for from the second air outlet of oven 1
122 hot winds out by, be provided with some independent cold air ducts 60 mutually in metal frame, it is described in the utility model
The making material of cold air duct 60 is metal, the trend and the direction phase of the hot wind in waste heat recovery part 6 of the cold air duct 60
Vertically, in use, the hot wind passed through out of waste heat recovery part 6 heats the cold wind in cold air duct 60 by heat transfer, heat
The hot wind that cold wind and the first air outlet 121 afterwards comes out is delivered back into roasting by the first exhaust fan 21 after being reheated by heater 3
In case 1；, will be extraneous new by waste heat recovery part 6 from the hot wind that the second air outlet 122 in oven 1 comes out in the utility model
Into cold air heating so that the heat of hot wind is fully utilized, is entered back into after cold air heating and profit carried out in oven 1
With moreover, cold wind in follow-up reheating link, due to having already passed through the heating of a waste heat recovery part 6, is heating
Heating at device 3 can faster reach the temperature of requirement, and the service life of heater 3 also can be longer, due to cold air duct 60
It is independent several mutually, therefore, the utilization rate higher of heat, also more economical environmental protection.
In the utility model, it is preferred that as shown in figure 3, the insufflation unit 4 includes upper blowing nozzle 41 and lower blowing nozzle
42, the upper blowing nozzle 41 and lower blowing nozzle 42 shift to install, the advantages of this arrangement are as follows, upper 41 He of blowing nozzle can be utilized
The air blowing support heating material 9 of lower blowing nozzle 42, forms suspension heated condition, not only saves support platform, structure is simpler
It is single, and the contact with support platform has been subtracted, dry effect also can be more preferable；In the utility model, cold wind after heating by
First exhaust fan 21 is respectively via the upper blowing nozzle 41 that the first air inlet 111 and the second air inlet 112 are transported in oven 1 with
Blowing nozzle 42.
In the utility model, it is preferred that in order to improve work efficiency, the quantity of the oven 1 can be two or two
More than, two or more oven 1 shares a waste heat recovery part 6, thus can be at the same time by the heat of multiple ovens 1
When gas uniformly ejects to newly into cold wind heat, firing rate faster, work efficiency higher；As shown in figure 4, i.e.
The quantity of the oven 1 is 4, the hot wind that 4 ovens 1 come out by waste heat recovery part 6 to newly into cold wind heat,
Work efficiency higher.
