The waste of resource.And in order to prevent unnecessary radiating from also needing to set many Insulations to incubator outer surface, due to
It is very high so as to accelerate the aging of the electric wire of heating tube to be incubated the temperature inside the box, easily burns electric wire.
Utility model content
The utility model provides a kind of efficient energy-saving air heater, it is therefore intended that solves the problems such as heat utilization ratio is low.
The technical scheme that the utility model solves above-mentioned technical problem is as follows：A kind of efficient energy-saving air heater, including
Housing, the housing are cylinder, and air inlet is provided with the bottom surface of housing, gas outlet, the housing are provided with the side of housing
Heat-insulation layer is cased with inwall, housing is equipped with least two built with the electric boiling plate being inserted perpendicularly into from side on heat-insulation layer bottom surface
Block back flow plate, heated air turn back at back flow plate, increase the residence time in preheater.
Further, the electric boiling plate at least two, there are multiple heating plates on each electric boiling plate, heating plate passes through
Supporting plate links together, and heating plate is shaped as arc or concave shape, and the heating plate of arc or concave shape can increase air
Contact area, and change air rectilinear motion route, increase the residence time between electric boiling plate.
Further, the heat-insulation layer is graphite collet, is resistant to very high temperature, has good heat insulation effect, no
Heat is caused to scatter and disappear, and pre-heat effect is more preferable.
Further, the electric boiling plate is fixed on housing by fixed plate.
Further, the electric boiling plate is connected to terminal box, and terminal box is connected to fuse, for protection circuit.
Further, temperature control system is connected with the side of the housing, the air themperature inside preheater can be monitored, temperature
Alarm is provided with control system, when temperature is too high, sends alarm；Thermoregulator is additionally provided with temperature control system, regulation electricity adds
The power output of hot plate.
Further, the opening of the heating plate on each electric boiling plate is collectively aligned or is open reversed arrangement, for extending sky
The gas residence time, improve air themperature.
Further, the opening of the heating plate be collectively aligned electric boiling plate orientation it is identical or on the contrary, for extending
Air residence time, improve air themperature.
Further, the back flow plate is shaped as linear or waveform, and can turn back air, extends air residence time.
The beneficial effects of the utility model are：By setting heat-insulation layer, reduce heat and scatter and disappear, and improve air heating effect
Rate；Fuse and temperature control system ensure that there is the abnormal safety with temperature preheater in the case of too high in circuit；Back flow plate
And electric boiling plate, time of the air in preheater is considerably increased, the quantity of heating plate can be reduced, saves cost, but heat
Effect is more preferable.
