Description
Technical field
The present invention relates to wallpaper production equipment technologies, more particularly, to a kind of box type hot air drying unit.
Background technology
Due to traditional wallpaper device drying device, mostly use steam or deep fat heat exchange greatly, by air heat after-blow to
Stock surface is dried.Using the equipment of heat transfer technology, thermal losses is larger in heat transfer process, and efficiency is relatively low；And
Indirect heat exchange equipment usually requires boiler central heating, boiler central heating generally use raw coal or heavy oil as fuel,
It will produce the harmful substances such as sulfur dioxide, flue dust in combustion process, pollute air, environmental protection is not up to standard to be unable to direct emission air
In, and boiler is pressure vessel, there are security risks.It is boiler additionally, due to indirect heat exchange heating plant, is carrying out
The steam or deep fat of whole system need to be carried out being heated to certain temperature when heating, therefore, the heating that when boiler startup needs
Time is long, and most manufacturers have a plurality of production line, boiler central heating, even if only opening a line, it is also desirable to by boiler
Overall startup, when only opening part producing line, thermal loss is huge, and energy utilization rate is relatively low.
Invention content
The purpose of the present invention is exactly in order to solve the deficiency of the prior art, and the one kind provided is improved with cost is reduced
Wallpaper produces the box type hot air drying unit of Drying Rates.
The present invention is to realize above-mentioned purpose using following technical solution：
A kind of box type hot air drying unit, the circulating fan mainly connected with burner and the two by baking oven are constituted, special
Sign is that the baking oven side is connected with waste discharge blower fan and waste discharge air hose, and circulating fan is connect by outlet air connecting tube with baking oven,
Thermocouple is provided in outlet air connecting tube, thermocouple connects the control of the natural gas air intake control system and circulating fan of burner
System, circulating fan air outlet are connect by flange with baking oven；Combustion box, burner connection burning are provided with outside the burner
Collection fire cylinder in case, and keep off fire cover in end set collects fiery cylinder top and is arranged fire resisting shield, structure in the insulating layer of fire resisting shield top
At hot wind babinet.
As a further illustration of the above scheme, the combustion box includes liner and shell, it is insulating layer among two layers, by
High temperature resistant alumina silicate fibre asbestos are constituted.
The combustion box bottom is provided with osculum.
It is provided with return air air hose between the waste discharge air hose and baking oven, is provided with except paper on the waste discharge air hose of return air air hose
Fleece；It is provided with fresh air air hose on the waste discharge air hose, fresh-air volume adjuster is provided on fresh air air hose.
Waste discharge blower fan adjuster is provided in the waste discharge blower fan.
It is additionally provided with combustion chamber partition board under the indoor burner of burning.
The present invention is using the attainable advantageous effect of above-mentioned technical solution institute：
One, box type hot air drying unit of the present invention uses natural gas for fuel, and in combustion box, cold air is directly added
Heat reduces energy loss when heat exchange, improves energy utilization rate.Combustion box is divided into liner and shell, is equipped among two layers resistance to
High temperature alumina silicate fibre asbestos board, has reached insulation effect, reduces the thermal loss of babinet, whole efficiency can reach 97% with
On.
Two, box type hot air drying unit is per color independent heat supply (i.e. per one device of color).Thermoelectricity is housed inside combustion box
It is even, can detection blower fan leaving air temp in real time, for thermocouple by the temperature feedback of detection to control system, system can be according to current work
The gas inlet amount and air inlet amount of burner is adjusted in condition, ensures that the temperature of wind turbine blowout is controlled in working range
Any one interior point, have reached the optimum state of using energy source.
Three, one of an important factor for drying wind speed dried is drying.Baking oven designs the side for using hot wind upper entering and lower leaving
Formula dries up plate surface ink to avoid hot wind, reduces the generation of defect rate.Baking oven designs liner and shell, due to drying
When case designs, hot wind uses upper entering and lower leaving, and therefore, the cross-sectional area of baking oven liner gradually decreases from the top down, to improve hot wind
Wind speed in liner, and liner is designed with tuyere, further increases wind speed when hot wind blows to stock.To improve
Whole Drying Rates.
Four, steam or hot oil type indirect heat exchange, due to having steam or hot oil pipeline, steam or deep fat inevitable in the duct
Heat loss is had, this partial heat loses in vain in steam or hot oil transfer.Box type hot air drying unit, combustion box and baking
Spacing is close, reduces the loss of heat in the duct, improves the utilization rate of the energy, reduce cost；In track
It is applied in equipment so that complete machine speed improves 50% compared with previous generation production lines, and energy cost has dropped 15%.
