The second vertical cloth wind through hole.The first cloth wind through hole tilts obliquely from the inside to the outside, the inner surface pair of the side wall of outer shell
Answer the first cloth wind through hole that some wind deflectors are set.The incline direction of the wind deflector and the first cloth wind through hole are on the contrary, and wind deflector
Size become larger from the bottom to top.The top surface of the shell sets safety valve.
Preferably, the top surface of the heating chamber is in funnel-form, and lowest part is located at the center of heating chamber top surface.
Preferably, the inner housing inner is additionally provided with some horizontal laminates, and the laminate is network structure.
Compared with prior art, air is blasted into heating chamber by air blower, and air added by electric heat source
Heat, high temperature air constantly rise after entering convection channel by air outlet.It is located at due to electric heat source in the heating chamber of bottom, mainly
Heated by way of cross-ventilation heat transfer, rather than heated using traditional heat transfer, solve local temperature difference
The problem of big so that the distribution of temperature is more balanced, stably.High temperature air is folded to during rising by wind deflector
Heating firing is carried out to moulded pottery not yet put in a kiln to bake from the first cloth wind through hole into inner housing inner afterwards.Because the size of wind deflector progressively becomes from the bottom to top
Greatly, so as to ensureing that enough high temperature airs can be folded to inner housing inner by each wind deflector from the bottom to top.Led to by the first cloth wind
Hole, the second cloth wind through hole, wind deflector cooperate so that the distribution of high temperature air is more uniform, so that inner housing inner
Heat it is more balanced.Remaining high temperature air can also enter inner casing by the way that the second cloth vent hole is descending at the top of convection channel
In so that heat is fully utilized.High temperature air reenters in heating chamber after exchanging heat with moulded pottery not yet put in a kiln to bake, and from return air inlet
Row heating, hence into next circulation, thus the waste heat of air after heat exchange is fully played, there is fabulous heat utilization
Rate.
Brief description of the drawings
Fig. 1 is internal structure schematic diagram of the present utility model；
Fig. 2 is A portions enlarged drawing in Fig. 1.
Embodiment
A kind of electrical kiln convection heat transfer' heat-transfer by convection device with reference to shown in Fig. 1 and 2, including convection cell 1 and adding positioned at the bottom of convection cell 1
Hot cell 2.The convection cell 1 includes inner casing 3 and shell 4, and convection channel 5 is formed between the inner casing 3 and shell 4.The heating
