Embodiment
The total design of the utility model is stock chamber and the ventilating duct of erectting side by side in the framework of cuboid, carries out grain drying operation.Introduce five kinds of embodiment around this design below.
The first embodiment: as shown in Figure 1, 2, the main body of this vertical air channel air curing cabin for food is the cuboid framework 1 forming with metal rod, framework 1 is four coated screen clothes 2 in side all around, framework 1 below is provided with grain unloading mouth 6 that can switch, height >=the length of framework 1, length: width=3-5: 1.Visible in conjunction with Fig. 3: the sieve 3 that multiple settings are housed in framework 1, sieve 3 is also the flat components being supported by screen cloth and four frames, each sieve 3 is divided into along the length direction of framework 1 space that multiple width does not wait the space in framework, wherein wider space is the stock chamber 4 of splendid attire grain, and narrower space is the ventilating duct 5 of not loading food.Stock chamber 4 upper and lower openings, circulation up and down, until nethermost grain unloading mouth 6.Visible in conjunction with Fig. 4 Fig. 5 Fig. 6: ventilating duct 5 at least upper end need to be airtight, can be airtight with screen cloth, also can be airtight with lath, preferably adopt the structure of Fig. 4, section is pointed shape.Stock chamber 4 setting alternate with ventilating duct 5, the width in stock chamber 4 and volume are ventilating duct 5 width and volume 2-4 times.
In experiment, select a kind of specification of optimization: the long 2800-3200mm of framework, wide 740-800mm, high 4000-5000mm.Conventional long 3000mm, wide 750mm, the high 4600mm of being of a size of at present.Its inner space is divided into upper and lower 4-6 layer by the trombone slide 7 of horizontal, every layer is separated into multiple stock chamber 4 and ventilating duct 5 by sieve 3, and the volume in stock chamber 4 is 2 times of ventilating duct 5, generally with the stock wide 100mm in chamber, the wide 50mm of ventilating duct is advisable, and the ventilating duct 5 of each layer is relative up and down.
When use, grain packs into from above, dirty successively, is full of stock chamber 4, and the natural wind circulating by ventilating duct 5 is dried.Because ventilating duct 5 is to be divided into by the plane sieve of erectting with stock chamber 4, ventilating duct 5 volumes are larger, are difficult for stopping up, and do not bear the pressure of vertical direction, and not fragile, the speed of drying grain is fast, and quality is good, is not prone to mouldy dead angle.
The second embodiment: as shown in Figure 7, it is basic identical that this vertical air channel air curing cabin for food and the first embodiment introduce, and difference is that the ventilating duct 5 of adjacent two layers staggers mutually.This structure is conducive to stirring and the upset of grain, and grain constantly changes the order between particle in flowing from the top down, makes drying condition more balanced, and dry mass significantly improves.
The third embodiment: as shown in Figure 8, the framework outside of this vertical air channel air curing cabin for food is provided with upwardly extending airduct 8, and airduct 8 upper ends are provided with booster 9.Visible in conjunction with Fig. 9 Figure 10: booster 9 is provided with deep bead 10, the upper end of deep bead 10 is higher than airduct 8, and deep bead 10 is rotationally connected by pivoted housing 11 and airduct 8 upper ends, and the rear end of pivoted housing 11 is provided with guide vane 12.Booster 9 can rotate with the wind under the effect of guide vane 12, makes the outside of deep bead 10 always relative with wind direction, and a side suitable for reading of blocking airduct 8, so that the discharge of airduct 8 interior air-flows.Visible in conjunction with Figure 11: airduct 8 communicates with each trombone slide 7 of framework 1, and trombone slide 7 is provided with wind hole 13.Because airduct 8 is very high, generally can reach 15-20m, the wind-force of upper end is larger, can make the interior formation negative pressure of airduct 8, the air-flow in framework 1 is drawn onto in airduct 8 by wind hole 13, then discharge from upper end, thereby the flow of air-flow in increasing air curing cabin for food, the dewatering efficiency of raising grain.
The 4th kind of embodiment: as shown in figure 12, the framework outside of this vertical air channel air curing cabin for food is provided with upwardly extending airduct 8, and wind-collecting cover 14 is equipped with in the upper end of airduct 8.Visible in conjunction with Figure 13 Figure 14, wind-collecting cover 14 is the little cone-shaped hoods in the large rear end of a kind of opening, rear end bending is downwards pegged graft with the rotation suitable for reading of airduct 8, guide vane 12 is equipped with in the rear end of wind-collecting cover 14, the opening of wind-collecting cover 14 is erect all the time windward, airduct 8 communicates with the trombone slide 7 of framework 1, and trombone slide 7 is provided with wind hole 13.This device makes the air-flow in high-altitude enter airduct 8 by wind-collecting cover 14, then goes out from the wind hole 13 of each trombone slide 7, in the middle of grain, pass through, thus the intensity of air-flow in increasing air curing cabin for food, the dewatering efficiency of raising grain.
The 5th kind of embodiment: as shown in figure 15, framework 1 outside of this air curing cabin for food is provided with upwardly extending airduct 8, wind wheel 15 is equipped with in the upper end of airduct 8, guide vane 12 is equipped with in wind wheel 15 rear ends, the rotating shaft 17 of wind wheel 15 drives air pump 16 by crank connecting link 19, the gas outlet of air pump 16 is connected with airduct 8, and airduct 8 communicates with the trombone slide 7 of framework 1, and trombone slide 7 is provided with wind hole 13.The kind of air pump 16 is a lot, can adopt the air pump of inflation, also can adopt air-breathing air pump, and its effect is all to make the interior generation air-flow of airduct 8, strengthens the circulation of air in air curing cabin for food, strengthens drying efficiency.Figure 16 has exemplified a kind of air pump 16 to airduct 8 interior inflations, as seen from the figure: the rotating shaft 17 of wind wheel 15 is arranged on support 18, crank connecting link 19 is installed in the rear end of rotating shaft 17, and crank connecting link 19 drives piston cylinder 20 to move up and down in airduct 8, and the end opening of piston cylinder 20 is provided with check valve 21.In the time that piston cylinder 20 upwards moves, check valve 21 is opened by gravity, and the air in airduct 8 moves on not understanding, and airduct 8 air suitable for reading also can enter airduct 8.In the time that piston cylinder 20 is descending, check valve 21 is closed, and the gas in airduct 8 is forced to press down, go out by the wind hole 13 of the trombone slide 7 in air curing cabin for food, thus the intensity of air-flow in increasing air curing cabin for food, the dewatering efficiency of raising grain.
