Mounting rack can be made to be adjusted to any angle and guarantee that upper quartz ampoule 5 is identical apart from upper color steel plate 1.Upper quartz ampoule 5 is evenly arranged in
On mounting rack 3, upper color steel plate 1 is toasted in fever after energization.
Lower preheating device is made of lower mounting rack 4, lower quartz ampoule 6, lower lifting screw rod 8.Lower mounting rack 4 and lower lifting screw rod
8 are connected by nut-screw rod, are adjustable the distance between lower quartz ampoule 6 and lower color steel plate 2.Lower quartz ampoule 6 is evenly arranged in lower peace
It shelves on 4, lower color steel plate 2 is toasted in fever after energization.
Preheating is closed around room 11 with insulation board.Entire preheating device, upper supporting roller 9, snub pulley 10 are in this envelope
Close space.
Upper color steel plate 1 and lower color steel plate 2 complete preheating by upper supporting roller 9, the conveying of snub pulley 10 respectively.
The shortcomings that preheating device, is as follows:
1, quartz ampoule baking color steel plate enough uniformly, and cannot be not easily controlled steel billet temperature.
2, foaming agent of the pentamethylene as hard polyurethane foams is commonly used in PU insulation board production process.However pentamethylene
Ignition temperature be 361 DEG C, cannot directly be contacted with quartz ampoule.
In order to make color steel plate reach the temperature of production requirement, Chang Xuan 1500w quartz ampoule, 1500w quartz pipe surface after energization
Temperature is 1200 DEG C.
Therefore, there are significant limitations for the preheating apparatus of the prior art.
Summary of the invention
The technical problem to be solved by the utility model is to provide a kind of heated air circulation type steel plate preheating apparatus, solve
Preheating device heats non-uniform problem in the prior art.
The utility model uses following technical scheme to solve above-mentioned technical problem:
A kind of heated air circulation type steel plate preheating apparatus, including the heater box being arranged between upper color steel plate and lower color steel plate
Body, the upper and lower surfaces inside heating compartment are respectively provided with heating tube, and radiation air is arranged in one end between upper color steel plate and lower color steel plate
Machine, in cabinet after heating tube heating, by blower by even heat distribute supreme color steel plate lower surface and lower color steel plate it is upper
Surface.
The heating tube is set as U-shaped, is arranged in the upper and lower surfaces of heating compartment.
Cooling stand is set between upper color steel plate and lower color steel plate, and heating compartment and cooling fan are arranged in the cooling stand
On.
The heating compartment includes at least two.
The bottom of the heating compartment is installed by shifting roller.
Compared with prior art, the utility model has the following beneficial effects:
1, the hot wind of heated air circulation type steel plate preheating apparatus circulation heats color steel plate, homogeneous heating, peace
Entirely, controllability is good.
2, heated air circulation type preheating solves producing line in color steel plate preheating, due to non-uniform temperature, local temperature
The excessively high problem for causing pentamethylene inflammable and explosive.
3, even heat is dissipated into preheating room using blower by heated air circulation type preheating apparatus, and even heat, energy consumption is more
It is low, more meet international industrial standard.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of preheating apparatus in the prior art.
