Description
Technical field
The utility model relates to baking equipment for preparatory treatment of tobacco, particularly relates to a kind of tobacco flue-curing airflow circulating air channel.
Background technology
In the middle of process prepared by tobacco leaf, need the program through overbaking, and the quality of baking will directly determine the quality of pipe tobacco, so the baking program of tobacco leaf just seems of crucial importance, for guaranteeing that the baking quality of tobacco leaf often needs the airflow circulating in tobacco flue-curing place specifically to design, hot blast is distributed more even, the baking of tobacco leaf is also more even.Existing circulation air path is mainly to utilize circulating fan that hot blast is sent into barn bottom or top reaches the object to tobacco flue-curing, this roasting mode is when being applied to large-scale barn, because barn area is limited compared with systemic circulation power of fan, in barn, hot air circulation is inhomogeneous, has baking dead angle.
Summary of the invention
Object for above-mentioned situation the utility model is just to provide the tobacco flue-curing airflow circulating air channel that a kind of hot blast distribution is evenly applicable to large-scale barn.
Its technical scheme is, a kind of tobacco flue-curing airflow circulating air channel, comprise cavity, in cavity, be provided with the dividing plate of vertical installation, dividing plate is by cavity one-tenth heating clamber placed separately and baking vessel, between dividing plate upper surface and cavity top, leave interval, form the structure that heating clamber and baking vessel upper end are communicated with, heater is housed in heating clamber, the top, bottom surface of baking vessel is provided with aerofoil, between the lower surface of aerofoil and the bottom surface of baking vessel, leave interval, form bellows, aerofoil is provided with a plurality of eyes of wind that are communicated with bellows, heating clamber bottom is provided with wind-tunnel, air generation plants is housed in wind-tunnel, the air inlet of wind-tunnel is communicated with heating clamber, the air outlet of wind-tunnel is communicated with bellows, one side of cavity is provided with charging aperture.
The utility model is simple in structure, utilize high temperature air density to be less than Cryogenic air, hot gas automatically floats and forms the principle of hot air convection, make for baking vessel, the dependence of circulating fan to be reduced greatly, baking dead angle is eliminated in each corner that hot blast can be uniformly distributed in to baking vessel for large-scale baking vessel, and the baking quality of tobacco leaf is more easily guaranteed.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of dividing plate.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further details.
As depicted in figs. 1 and 2, a kind of tobacco flue-curing airflow circulating air channel, comprise cavity, in cavity 1, be provided with the dividing plate 2 of vertical installation, dividing plate 2 is by cavity 1 one-tenth heating clamber 3 placed separately and baking vessel 4, between dividing plate 2 upper surfaces and cavity 1 top, leave interval, form the structure that heating clamber 3 and baking vessel 4 upper ends are communicated with, heater 5 is housed in heating clamber 3, the top, bottom surface of baking vessel 4 is provided with aerofoil 6, between the bottom surface of the lower surface of aerofoil 6 and baking vessel 4, leave interval, form bellows 7, aerofoil 6 is provided with a plurality of eyes of wind 8 that are communicated with bellows 7, heating clamber bottom is provided with wind-tunnel 9, air generation plants 10 is housed in wind-tunnel 9, the air inlet of wind-tunnel 9 is communicated with heating clamber, the air outlet of wind-tunnel is communicated with bellows 7, one side of cavity 1 is provided with charging aperture.
Said heater 5 is installed on the sidewall of heating clamber top, and heater comprises air heat energy heater 11 and electric heating tube 12.
Said aerofoil 6 is spliced by rectangular slab of uniform size, the lower surface of aerofoil 6 is connected with bracing frame 13, bracing frame 13 is fixedly installed on the inwall of baking vessel 4, bracing frame 13 is network, the area of each grid equals to form the area of each rectangular slab of aerofoil 6, and each rectangular slab is fixedly mounted on the upper surface of bracing frame 13.
Said wind-tunnel bag 9 is drawn together the air inlet of the rectangular pyramid shape arranging in bottom of heating chamber, and air inlet is communicated with air outlet through columniform passage 14, and air outlet is communicated with bellows 7, and circulating fan 15 is housed on the inwall of passage 14.
When the utility model is used, air in 5 pairs of heating clambers 3 of heater heats, the air that air generation plants 10 is over the interior heating of heating clamber 3 is sent hot blast into bellows 7 through wind-tunnel 9, hot-air density in bellows 7 is less than the density of baking vessel's 4 interior cold airs, the eye of wind 8 floatings of hot blast on aerofoil 6 enter the space in baking vessel 4, product to baking vessel's 4 interior placements toasts, simultaneously because the effect of circulating fan 15 makes air pressure in heating clamber 3 lower than the air pressure of baking vessel's 4 interior air, under the effect of barometric gradient, air in baking vessel 4 flows to heating clamber 3, form the convection circulation of baking vessel 4 and heating clamber 3 interior air, reach the object of even baking.
The utility model is simple in structure, utilize high temperature air density to be less than Cryogenic air, hot gas automatically floats and forms the principle of hot air convection, make for baking vessel, the dependence of circulating fan to be reduced greatly, baking dead angle is eliminated in each corner that hot blast can be uniformly distributed in to baking vessel for large-scale baking vessel, and the baking quality of tobacco leaf is more easily guaranteed.
