Abstract
The utility model discloses a uniform drying device for a stem fluidized bed. The device comprises a vibrated fluidized bed mesh bottom plate for conveying a stem, wherein the bottom surface of the mesh bottom plate is provided with a hot air nozzle for blowing the stem on the mesh bottom plate, and the mesh bottom plate is in a ladder shape; and the height of the front section of the mesh bottom plate is higher than that of the rear section of the mesh bottom plate in the travelling direction of the stem. The uniform drying device provided by the utility model realizes the effect of re-mixing materials by blowing away the materials through wind power and utilizing the join fall of conveying devices so as to improve the moisture uniformity of the end surface of the dried stem.
Description
Technical field:
The utility model relates to a kind of stem fluid bed uniform dryer.
Background technology:
The stem fluidized bed drying is as thermal source take steam, stem after the heating and moistening processing is formed quick condition because of the effect that is subject to hot blast in vibrated fluidized bed, and fully mix with hot blast and to carry out heat exchange, hot blast provides transpiring moisture required heat to stem in the stem dry run, simultaneously absorb again the water vapour that is evaporated in the stem, make stem be able to rapid dryness finalization.Because of material along continuous straight runs throwing forward in the continuous motion, stem for lighter weight, high in the cell body excited frequency, in the small feed status situation of amplitude, present the slowly forward displacement of stem drying layer integral body, therefore, in stem drying layer dry run, enter from stem that the upper lower floor of formed stem end face remains to dry outlet always behind the dry cell body.Hot blast passes fluid bed and wet stock heat exchange from bottom to top, the difference of material surface, bottom and intermediate layer moisture evaporation rate, it is relatively poor to cause forming water uniformity on the material section, stem fluid bed end face moisture content extreme difference is larger, fluid bed outlet moisture content standard deviation is higher, directly affects stem whole cut rate and filling value.Adopt at present adjustment, the adjustment of Yi Er district temperature, the moisture content of outlet of wind speed and deflector to participate in the methods such as FEEDBACK CONTROL, DeGrain.
Summary of the invention:
For overcoming the defective of prior art, the purpose of this utility model is to provide a kind of stem fluid bed uniform dryer, adopt wind-force to dispel material and utilize the linking drop of conveying equipment to reach the effect that material mixes again, to improve the water uniformity of the dry rear end face of stem.
The utility model technical solution problem adopts following technical scheme:
A kind of stem fluid bed uniform dryer, comprise the vibrated fluidized bed mesh base plate for delivery of stem, being provided with hot-blast spray nozzle at the place, bottom surface of described mesh base plate blows the stem on the mesh base plate, described mesh base plate is set to stepped, on the direct of travel of stem, the height of leading portion mesh base plate is higher than the height of back segment mesh base plate.
In the stepped burst of described mesh base plate, the air outlet of described hot-blast spray nozzle is made as duckbill.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
The tobacco stem shred fluidized bed drying equipment cell body of the utility model is in conveying, dry stem, stem is rolled and dispel, the upper lower floor that reaches former stem end face mixes stack again, the purpose of tumble dry processing makes the dry end face moisture of stem of fluid bed outlet more even again.
Description of drawings:
Fig. 1 is structural representation of the present utility model, and arrow is the blowing direction of hot blast among the figure.
Number in the figure: 1 mesh base plate, 2 hot-blast spray nozzles, 3 bottom drying layers, 4 middle part drying layers, 5 top drying layers, 6 air outlets.
Below pass through the specific embodiment, and the utility model is described in further detail by reference to the accompanying drawings.
The specific embodiment:
Embodiment: in conjunction with Fig. 1, the stem fluid bed uniform dryer of present embodiment, it is more even that purpose is to improve the dry moisture of stem of fluid bed outlet, shown in Figure 1, stem is fed forward by the fluid bed mesh base plate 1 of vibration, the stem that is provided with on 2 pairs of mesh base plates of hot-blast spray nozzle at the place, bottom surface of mesh base plate blows, stem is in traveling process, formed bottom drying layer 3, middle part drying layer 4 and top drying layer 5, the stem uneven drying of upper, middle and lower three parts is even, in order to change this phenomenon, the utility model mesh base plate is set to stepped, namely be on the direct of travel of stem, the height of leading portion mesh base plate is higher than the height of back segment mesh base plate, and the air outlet 6 of the stepped burst of mesh base plate is made as duckbill, stem is in traveling process, when arriving the burst of mesh base plate, because Action of Gravity Field and the effect that dispels hot blast, the stem that each layer degree of drying differs mixes stack again, and mixing repeatedly stack and dry run again, so that limited dryer section is fully utilized, and reach the purpose of stem uniform drying, thereby improve the filling value of stem and the control accuracy of moisture.
Claims (2)
1. stem fluid bed uniform dryer, comprise the vibrated fluidized bed mesh base plate (1) for delivery of stem, being provided with hot-blast spray nozzle (2) at the place, bottom surface of described mesh base plate blows the stem on the mesh base plate, it is characterized in that, described mesh base plate is set to stepped, on the direct of travel of stem, the height of leading portion mesh base plate is higher than the height of back segment mesh base plate.
2. a kind of stem fluid bed uniform dryer according to claim 1 is characterized in that in the stepped burst of described mesh base plate (1), the air outlet of described hot-blast spray nozzle is made as duckbill.
