Detailed description of the invention
For summary of the invention of the present invention, Characteristic can be understood further, hereby exemplify following examples and be described in detail as follows:
Refer to Fig. 1, the present invention includes that supported by multiple column 3, columniform casing 7, the roof of casing 7 is provided with exhaust duct 2 and the feeding port 8 with buckle closure, and exhaust duct 2 is for discharging the moist waste gas in casing 7, and the materials such as vegetables and fruits insert the inner chamber of casing 7 via feeding port 8.
Vertical upper hot air duct 14 is installed the bottom wall central of casing 7 is affixed, is provided with woven wire 5 at the top of upper hot air duct 14 inner chamber.Also comprise the air-heater 4 be fixedly mounted on column 3, be connected with lower end with buckle closure, vertical lower hot air duct 6 at its air outlet, upper hot air duct 14 and lower both hot air ducts 6 vertically align.
Sleeve 12 is arranged with at the middle part of a column 3, the outer wall of sleeve 12 is connected with the flap 13 of level, the plate body of flap 13 is provided with vertical docking pipeline 15, in docking pipeline 15, rotational flow generator is installed, docking pipeline 15 seals and embeds above between hot air duct 14 lower end and lower hot air duct 6 upper end, forms complete hot blast feeding pipeline.It should be noted that: between the lower end of docking pipeline 15 and upper hot air duct 14 and the upper end of lower hot air duct 6, should positiver sealing be carried out, prevent hot blast to run off and cause additional energy, positiver sealing can adopt as inferior mode realizes: arrange sealing rubber ring at the two ends up and down of the upper end of the lower end of upper hot air duct 14 and lower hot air duct 6 and docking pipeline 15, realizes sealing by embedding crimp.
The dry-heat air that air-heater 4 produces imports the inner chamber of lower hot air duct 6, upwards change swirling two-phase flows into through docking pipeline 15 and rotational flow generator afterwards, the inner chamber upwards entering casing 7 through upper hot air duct 14 and woven wire 5 again carries out brute force to material and blows stirring, makes material in casing 7, realize boiling type and stirs dry.The effect arranging woven wire 5 prevents from material from dropping to enter in hot blast feeding pipeline; The effect arranging buckle closure in the lower end of lower hot air duct 6 is by regularly opening this buckle closure, is discharged by the water accumulated in lower hot air duct 6.
In the present embodiment, in order to provide dissimilar boiling effect to dissimilar material, the docking pipeline 15 arranged on flap 13 plate body is into the multiple of fan-shaped distribution, and the flow velocity being arranged on the rotational flow generator in each docking pipeline 15 is different.Like this, for dissimilar material (dividing according to material monomer average weight or average grain diameter), can making specifically to dock pipeline 15 and rotational flow generator access hot blast feeding pipeline by rotating flap 13, ensureing the spiral flow fluidized effect of material.
Also comprise the through discharge pipe 10 being connected to the discharging blower fan 1 in the middle part of casing 7 sidewall and being arranged on casing 7 sidewall of air outlet, discharging blower fan 1 and the centerline collineation both discharge pipe 10, be provided with Electric air valve 9 at the inner chamber of discharge pipe 10.Both horizontally-opposed discharging blower fan 1 and discharge pipe 10 are for blowing discharging to dried material, after Electric air valve 9 is opened, both air-heater 4 and discharging blower fan 1 coordinate, by material upwards boiling type apply horizontal air-flow while blowing afloat, material is laterally blowed and enters discharge pipe 10 and discharge, without the need to manual intervention.
In the present embodiment, for the ease of receiving dried material, being provided with the guide webmaster 11 oliquely downward tilted in the outer end of discharge pipe 10, can be metal material or plastic material etc.Hot blast is entrained with dried material and discharges via discharge pipe 10, and after entering guide webmaster 11, hot blast scatters and disappears via mesh, weaken the encapsulation of material, and the downward sedimentation of material, discharges along guide webmaster 11, arranges splicing basket and receives material.
Also comprise the return air duct 17 with humidity-discharging device 16, its upper end is connected to exhaust duct 2, lower end is connected to the return air inlet be opened on casing 7 diapire, in return air duct 17, be also provided with axial flow blower 18.The moist hot gas sent by exhaust duct 2 enters return air duct 17, and when humidity-discharging device 16, the moisture in hot gas is removed, and again forms dry-heat air.Humidity-discharging device 16 can adopt various structures form, as: comprise the housing through with return air duct 17 and be located in this housing, to be connected with cooling medium cooling coil, being provided with drainpipe in the bottom of housing.Moisture in hot gas meets cooling coil liquefaction, discharges through drainpipe.
