Description
Technical field
A kind of high thermal efficiency hot-blast stove is the utility model is related to, belongs to the energy-saving apparatus field of thermal kiln furnace.
Background technology
In ceramics and refractory material production field, some refractory products or special ceramics product need to use temperature some higher
Hot blast be dried, such as with the hot blast for being more than 300 DEG C of even more high some temperature.And produced by our usual kiln productions
Hot blast temperature, the either remaining waste heat air themperature got off of exhaust gas temperature or kiln itself is not very high, mostly
250 DEG C of little Yu, it is even lower.Cannot meet if obviously drying some particular products using kiln waste heat in itself will
Ask, this requires other thermal source to meet this requirement.In conventional produce reality, we are generally with increase by one
Platform small-sized air heating furnace meets the requirement in this production, but our conventionally used this small-sized air heating furnaces, is all often
The structure type of a subsidiary large-scale burner, the disadvantage of this structure type is that energy consumption is higher, and hot blast temperature is bad
Control, can not realize temperature automatically controlled by product drying temperature curve requirement, and kiln external skin temperatures are higher, service life of equipment
It is severely impacted, and later period maintenance is costly.
Utility model content
The purpose of this utility model is to propose a kind of high thermal efficiency hot-blast stove, the high thermal efficiency hot-blast stove economy and reality
With, it is compact-sized, occupy little space, hot blast temperature can be realized and automatically controlled, and disclosure satisfy that different product drying process requirements, and
And can protection equipment, extend the service life of equipment.
High thermal efficiency hot-blast stove described in the utility model, including kiln body skeleton, burner and hot-air system is taken out, kiln body bone
Hollow cavity is provided with inside frame, and the side wall of kiln body skeleton one embeds and is provided with burner, and hot-air system is taken out in opposite side connection；It is provided with
The side kiln body skeleton wall of burner is provided with an air inlet, and secondary air is provided between hot-air system and kiln body skeleton taking out
Mouthful；Taking out hot-air system includes temperature controller and blower fan, and secondary air inlet is between kiln body skeleton and blower fan, temperature controller
Between secondary air inlet and blower fan, temperature controller connection control unit, control unit connection power supply；Kiln body skeleton hot blast
Exit is provided with thermo detector, thermo detector connection control unit.
In use, burner combustion, pressure difference caused by the flame injection of burner makes the air of an air inlet automatic
Introduce in the hollow cavity of kiln body skeleton, once uniformly mixing, the burning for reaching flame and air are abundant；Then the heat after burning
General mood body is extracted out by the hot-blast outlet of kiln body skeleton, and drop is mixed after the air of secondary air inlet is mixed into during extraction hot blast
Low-heat general mood temperature, according to needs are dried, take out hot-air system and automatically adjust the hot blast gas temperature being extracted.The one of hot-blast stove
Secondary air inlet can both play combustion-supporting effect, can moderately reduce flame temperature again.Hot blast gas meeting before into blower fan
Temperature controller thermometric is first passed through, when temperature is too high, signal can be transmitted to control unit by temperature controller, and control unit will be controlled
Secondary air inlet processed increases air inflow, reduces extracted out hot blast gas temperature, meets dried product technological requirement.From kiln body
The hot blast gas that skeleton is extracted out is sampled thermometric in time, is advantageous to adjust the intake of secondary air inlet, is adjusted hot blast in time and is gone out
Mouth temperature, the defects of preventing from causing dried product to ftracture.
Preferably, barricade is set in the hollow cavity of described kiln body skeleton, hollow cavity is divided into two by barricade, and
Barricade lower part is provided with some logical fire holes, prevents from floaing on flame, and prevent flame to be sucked away in hot-blast outlet.
Preferably, the cavity close to an air inlet separated by barricade accounts for the 1/2-4/5 of whole hollow cavity.
Preferably, the hollow cavity of described kiln body skeletal internal scribbles refractory material.
Possessed beneficial effect is the utility model compared with prior art：
The utility model is reasonable in design, economical and practical, compact-sized, occupies little space, and taking out hot-air system can examine
Calorimetric general mood temperature, and the temperature of hot blast gas can be extracted out by the size adjustment of secondary air inlet intake in time,
So as to ensure that drying system is stable, dried product qualification rate is improved, reduces cost of equipment maintenance and production cost.

Embodiment
The utility model is described further below in conjunction with the accompanying drawings：
Such as Fig. 1, high thermal efficiency hot-blast stove described in the utility model, including kiln body skeleton 3, burner 1 and hot blast system is taken out
System, the inside of kiln body skeleton 3 is provided with hollow cavity 11, and the side wall of kiln body skeleton 3 one embeds and is provided with burner 1, opposite side connection
Take out hot-air system；The wall of side kiln body skeleton 3 provided with burner 1 is provided with an air inlet 2, is taking out hot-air system and kiln body skeleton
Secondary air inlet 7 is provided between 3.In combustion process, one time air inlet 2 can both play combustion-supporting effect, can moderately drop again
Low flame temperature.
In the present embodiment：Taking out hot-air system includes temperature controller 9 and blower fan 10, and secondary air inlet 7 is located at kiln body skeleton
Between 3 and blower fan 10, temperature controller 9 is located between secondary air inlet 7 and blower fan 10, and temperature controller 9 connects control unit,
Control unit connect power supply, into blower fan 10 before hot blast gas can first pass through the thermometric of temperature controller 9, when temperature is too high
When, signal can be transmitted to control unit by temperature controller 9, and control unit will control secondary air inlet 7 to increase air inflow, make to be taken out
The hot blast gas temperature gone out reduces, and meets dried product technological requirement；Barricade 4, gear are set in the hollow cavity 11 of kiln body skeleton 3
Hollow cavity 11 is divided into two by wall 4, and the lower part of barricade 4 is provided with some logical fire holes 5, prevents from floaing on flame, and prevent
Flame is sucked away in hot-blast outlet 6, and the cavity close to an air inlet 2 separated by barricade 4 accounts for whole hollow cavity 11
2/3；Thermo detector 8 is provided with the hot-blast outlet 6 of kiln body skeleton 3, thermo detector 8 connects control unit, is extracted out from kiln body skeleton 3
