Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and advantage clearer, below by drawings and Examples, right
Technical scheme is described in further detail.It should be appreciated that specific embodiment described herein is only used
In the principle of the explanation present invention, it is not intended to limit the present invention.
If Fig. 1 is the tempering furnace structure using tradition stirring temperature equalization system.12 meters of long bodies of heater just need six sets to stir system
System 1, manufacturing cost increases, and fault rate increases, and customer using cost increases；If body of heater the widest point, for from fan farther out
Place is relatively slow due to air velocity, and air heat exchange is uneven, may result in temperature drift or on the low side at this.
If Fig. 2 is the tempering furnace structure using built-in Cycling hot-blast heating.The built-in Cycling hot-blast heating of described net belt type returns
Stove, including hot blast internal circulation system, described hot blast internal circulation system includes the gas being positioned at described hot blast internal circulation system top
The body thermal treatment zone 2, being positioned at the item for disposal thermal treatment zone 3 of described hot blast internal circulation system bottom, spiral case blower fan 4, spiral case blower fan is system
Operating power source, makes this regional gas stream circulate by suction with blowing；Do not interfere with the temperature of other temperature controlled region.Blower fan feature is
Wind Volume, little pressure.In Wind Volume can make the unit interval, realization repeatedly circulates；Little pressure can make fan outlet air velocity
Will not be too fast, so that air-flow fully heats in the thermal treatment zone.It is provided with gas between the gas thermal treatment zone and the item for disposal thermal treatment zone
The thermal treatment zone and item for disposal thermal treatment zone demarcation strip 5；Air-flow accelerator card 6, causes air flow through the structure that region is tapered, accelerates to air-flow,
Allow gas to get at and reach at blower fan suction inlet, it is achieved the interior circulation of air-flow；Gas-flow deflector 7, makes the gas that blower fan is the most heated
Stream becomes opposite direction motion, heats to from lower floor's item for disposal thermal treatment zone described heated air-flow and returns formation circulation；Add
Hot device 8, the gas heating of fan outlet.Net belt type of the present invention built-in Cycling hot-blast heating tempering furnace and heating side thereof
Method makes in-furnace temperature be evenly distributed, outside same section temperature difference is greatly reduced, also have minimizing manufacturing cost, energy-conservation, noise is little, dimension
Protect the advantages such as convenient.As used the tempering furnace structure of built-in Cycling hot-blast heating in Fig. 2,16 meters of long tempering furnaces only employ one
Individual stirring system, two Cycling hot-blast heating systems.The Wind Volume spiral case blower fan used due to blower fan, can make blower fan blow out
Gas is full of whole zone of heating, guides through deflector, blow forward after lower floor's workpiece layer after making gas fully heat, and gives place
Reason product heat.Whole tempering furnace is divided into four districts, temperature control one district, temperature control two district, temperature control three district, temperature control four district.Each temperature controlled region
Between be provided with demarcation strip 9.There is single temperature-controlling system in each district, and air-flow is in each district inner loop, the gas in each district
As heat exchange medium, being heated gas by gas and add hot gas to item for disposal and be heated, whole flow process is constantly followed
Ring, to workpiece heat, both ensure that the gas temperature uniformity of surface of the work, in turn ensure that item for disposal was fully heated.Every two
Being provided with bottom subregion plate 11 between individual temperature controlled region, moves in item for disposal 10 direction to the right along figure, makes the hot air circulation direction can not
Reversely.
Nearly 20 meters of the described whole equipment of tempering furnace structure, foraminous conveyer 12 is wide 1.6 meters, temperature control one district and temperature control two district because
Heater profile is relatively tightr, and every district is comparatively short, and workpiece is in temperature raising period, heater full power operation, so often using
Use structure.Temperature control three district and temperature control four district are in heat preservation zone, are the significant points of tempering furnace, the most long, use hot air circulation
Heating arrangement.
Preferably, the item for disposal of the item for disposal thermal treatment zone arranges the fixing direction of motion, makes the hot air circulation direction can not be reverse.
This Cycling hot-blast heating system item for disposal moves from left to right as shown in Figure 2, and hot air circulation direction can not be reverse, and item for disposal is logical
Although passing through heating zone when crossing this region, but workpiece temperature being likely not to have and reaches design temperature, if airflow direction fortune
Dynamic, then the highest wind of heat can first with cold absorption surface, when arriving this temperature controlled region end, gas flow temperature can reduce, thus
The temperature in the next district of impact.The point for measuring temperature in whole district, at the exit flow return that gas heats, makes the reality that item for disposal heats
Border temperature is the most identical with design temperature, reduces the temperature difference.
Preferably, point for measuring temperature is set at the exit flow return of gas heating.
Preferably, described net belt type built-in Cycling hot-blast heating tempering furnace is splicing structure.
A kind of by hydronic method in described net belt type built-in Cycling hot-blast heating tempering furnace hot blast, utilize spiral case
Blower fan, the gas making a certain region heated fully flows and mixes preheating, then blows to temperature distribution evenness requirement high
Region is to workpiece heat, then by blower fan, this portion gas is sucked, and is again passed to the thermal treatment zone, so that gas forms circulation
Flowing, it is achieved the uniform heating of workpiece.
Preferably, the gas thermal treatment zone and item for disposal thermal treatment zone demarcation strip are used between the gas thermal treatment zone and the item for disposal thermal treatment zone
5, make thermal source separate with item for disposal, prevent heater 8 from causing hot-spot directly to workpiece heat；Make upper and lower two-layer different directions
Air-flow non-interference, air-flow is heated in the gas thermal treatment zone, is then passed to the item for disposal thermal treatment zone.
Preferably, the air-flow using gas-flow deflector to make blower fan the most heated becomes opposite direction motion, at lower floor
The reason product thermal treatment zone is heated to item for disposal and returns formation circulation.
Device of the present invention is splicing structure, and assembly and disassembly is easy to maintenance.
Above-described detailed description of the invention, has been carried out the purpose of the present invention, technical scheme and beneficial effect further
