The concrete structure of mould preheating device 1 according to embodiments of the present invention is described below with reference to Fig. 1-Fig. 2.
As Figure 1-Figure 2, mould preheating device 1 according to embodiments of the present invention includes housing 100 and backplate 300.Shell
Combustion chamber 110 is limited in body 100, gas access 120 and the flame export 130 of combustion chamber 110 are communicated with housing 100.
Backplate 300 is connected to the side with flame export 130 of housing 100, and backplate 300 is towards close to the direction of flame export 130
Tilt.
It is understood that mould of embodiment of the present invention preheating device 1 is in use, mould preheating device 1 is put
It is placed in below mould, then input compressed air and fuel gas in combustion chamber 110, are produced after igniting at flame export 130
Light a fire flame, it is possible thereby to realize the pre- hot function to mould.Because the side with flame export 130 of housing 100 is provided with
Towards the inclined backplate 300 in the direction of flame export 130, backplate 300 can play the effect gathered to the flame of flame export 130,
Enhance pre-heat effect.In summary, the structure very simple of mould preheating device 1 of the embodiment of the present invention, production cost is relatively low,
Very easy to use, and mould can be directly heated, preheating area is larger, and heat transfer efficiency is higher, can be compared with
Moisture on good evaporation mould.
Mould preheating device 1 according to embodiments of the present invention, due to limiting combustion chamber 110, and housing in housing 100
It is provided with finding inclined backplate 300 close to flame export 130 on 100 side with flame export 130, simplifies mould
Have the structure of preheating device 1, reduce the production cost of mould preheating device 1, and gather flame because backplate 300 has
Effect, improves heat transfer efficiency, enhances pre-heat effect.
Additional description is needed, can be by the mould of the embodiment of the present invention when there is multiple moulds to need to be preheated
Preheating device 1 is fixed on an ad-hoc location, and multiple moulds are being sequentially transmitted into mould preheating device 1 just using transport mechanism
Top is preheated.Thus, it is possible to be continuously fully warmed-up to multiple moulds using a mould preheating device 1, shorten
Preheating time, reduce preheating cost.
In certain embodiments, housing 100 is formed as cuboid.Certainly, housing 100 may be formed as square, and half
The other shapes such as spheroid.It should be noted that foregoing description is only the example description to the profile of housing 100, it is not to housing
The specific restriction of 100 profiles, the shape of housing 100 can be designed according to the size and shape of mould in actual production process
And size.
In certain embodiments, as shown in figure 1, mould preheating device 1 also includes gas inlet pipe 200, gas inlet pipe
200 are connected with gas access 120.Thus, fuel gas and compressed air can be passed through combustion chamber by gas inlet pipe 200
In 110, the probability that fuel gas leaks is reduced, is avoided because security incident caused by combustible gas leakage occurs.
Alternatively, fuel gas is natural gas.Certainly, fuel gas can also arbitrarily combustible gas.
Specifically, gas inlet pipe 200 includes the first branch pipe 210 and the second branch pipe 220, the first branch pipe 210 and second
At least one in pipe 220 is directly connected with gas access 120.It is understood that compressed air and fuel gas can be distinguished
Combustion chamber 110 is passed through from the first branch pipe 210 and the second branch pipe 220, thereby ensures that the fuel gas before combustion chamber 110 is passed through
It will not be mixed with compressed air, improve combustion safety.
In some optional embodiments, as shown in figure 1, the first branch pipe 210 is connected with gas access 120, the second branch pipe
220 are connected to the middle part of the first branch pipe 210.It is understood that the second branch pipe 220 is connected to the middle part of the first branch pipe 210, can
To realize fuel gas and compressed air before combustion chamber 110 is passed through, in the first branch pipe 210 and the junction of the second branch pipe 220
Due to two strands of air-flows liquidate effect fuel gas and compressed air can be sufficiently mixed, compared to two kinds gases are into combustion chamber
Situation about being remixed after 110, such hybrid mode is more uniformly distributed with causing two kinds of gas mixings, so as to improve fuel gas
Efficiency of combustion.Certainly, two gas accesses 120, the first branch pipe 210 and a gas access 120 can also be provided with housing 100
It is connected, the second branch pipe 220 is connected with another gas access 120.
Specifically, the angle between the axis of the axis of the first branch pipe 210 and the second branch pipe 220 is 90 °.It can so make
It is vertical to obtain the flow direction of two strands of air-flows, improves the effect of liquidating of two strands of gas, further improves the mixing of two kinds of gas
The uniformity afterwards.
In certain embodiments, the first branch pipe 210 is provided with the first on-off valve (not shown) and/or the second branch pipe 220
It is provided with the second on-off valve (not shown).Specifically, in the embodiment having, it is logical that only the first branch pipe 210 is provided with first
Disconnected valve；In the embodiment having, only the second branch pipe 220 is provided with the second on-off valve；In the embodiment having, the first branch pipe 210
The first on-off valve is provided with, the second branch pipe 220 is provided with the second on-off valve.It is understood that this has on-off valve on branch pipe
The ratio of the fuel gas for being passed through combustion chamber 110 and compressed air can be adjusted, fuel gas can fully burn, avoid by
Pernicious gas is produced in fuel gas burn incompletely, the phenomenon for improving potential safety hazard occurs.
In some optional embodiments, gas inlet pipe 200 is welded to connect in the side wall of housing 100.Thus, it is possible to
Ensure gas inlet pipe 200 and the obturation effect of the junction of housing 100, reduce the risk of combustible gas leakage.Certainly, gas
Access tube 200 can also use other connected modes such as bonding to be connected in the side wall of housing 100.
In certain embodiments, as Figure 1-Figure 2, backplate 300 is two, and two backplates 300 are respectively provided at housing 100
Relative two side wall on, and two backplates 300 towards close to mutual direction extend.Specifically, backplate 300 prolongs
The angle for stretching direction and the upper surface of housing 100 is 60 °.It should be noted that the bearing of trend of backplate 300 and housing 100
The angle of upper surface is excessive, then the gather effect of backplate 300 can be caused bad, it is impossible to collect Flame well；Angle is too small, shield
Plate 300 serves suppression to flame so that the height of flame is relatively low, reduces heat transfer efficiency.It is demonstrated experimentally that work as,
When the bearing of trend of backplate 300 and the angle of the upper surface of housing 100 are 60 °, flame height is both can guarantee that, fire can be ensured again
Flame gather effect.Certainly, the angle of the convenient upper surface with housing 100 of extension of backplate 300 is not limited to 60 °.
Specifically, backplate 300 is integrally formed on housing 100.Certain backplate 300 can also use the other modes such as welding
