Position relative with inlet point 6 in shell 25 connects hot-blast outlet pipe 26, and the second valve 14 is installed on hot-blast outlet pipe 26, is used for regulating the length of the halt of hot blast in outer chamber 37.As shown in Figure 1, hot blast induction pipe 22 and hot-blast outlet pipe 26 are arranged on respectively the both sides of the length direction of shell 25, and the passage that hot blast is passed through between inner casing 24 and shell 25 passes through the almost whole length of whorl, thereby further increases area of heating.
Except steam pipe 11 is communicated with the inflow point of hot-blast outlet pipe 26 at dust exhaustor 16, dust exhaustor 16 inlet pipes are installed heat indicator 15, for detection of dust exhaustor 16 gasinlet temperatures, the highest temperature that allows lower than dust exhaustor 16 when dust exhaustor 16 gasinlet temperatures in service should be higher than 105 ℃, purpose are to guarantee that moisture content in gas condenses on can the element in dust exhaustor 16 to avoid simultaneously element in high temperature scaling loss dust exhaustor 16.
The outlet pipe of dust exhaustor 16 is connected with the induction pipe of induced draft fan 17, and the effect of induced draft fan 17 is to drawing the gas of the hot blast that is used for heating and material generation.The dirt that captures in dust exhaustor 16 reenters double-helical discharge end, avoids loss of material.
The first stay bearing plate 20 and the second stay bearing plate 27 are horizontal plate, all directly are welded on the bottom of the shell 25 of double helix device, are used for support motor 1, reductor 2, clutch shaft bearing 4 and the second bearing 19.
Fig. 2 is the schematic diagram of two spiral combinations.Two spiral levels are also placed abreast, and the feed end of the first axle 29 and the second axle 32 is installed respectively the gear 28 of same model, 31, two gears 28,31 intermeshing.Coupler 3 and the first axle 29 are connected and rotate with any axle of being connected in axle 32, (as: coupler 3 is connected with the first axle 29 adapter shaft by another root axle rotation of gear driven, coupler 3 rotates and drives the first axle 29 rotations, the first axle 29 rotation driven gears 28 rotate, because thereby the intermeshing driven gear 31 of gear 28 and gear 31 rotates, gear 31 drives again the second axle 32 and rotates).By the rotation of two spirals, thereby realization is to the conveying of material.
In the utility model, the first axle 29 and the second axle 32, gear 28 and gear 31, blade 30 and blade 33 model material both are identical.Blade 30 edges and the second axle 32 shortest distances are 20mm approximately.
Fig. 3 and Fig. 4 are the combination schematic diagrams of inner casing 24, shell 25 and cover plate 7.Inner casing 24 and shell 25 all have the outward flange of level, and outward flange in the vertical direction both is concordant.The outward flange of inner casing 24 and shell 25 is porose, both connect by the bolt that passes the hole and both between have resistant to elevated temperatures packing seal to seal.
The following describes the principle of work of the double helix feeding device with functions/drying of an embodiment of the present utility model.
Moisture not higher than 25% and the bulk APV that is not more than 50 * 50 * 30mm enter double-helical inner cavity chamber 36 by inlet point 6, by the rotation of two screw shafts in inner cavity chamber 36, APV is transported to discharging opening 21.Blade 30 and blade 33 carry out fragmentation to block APV in rotation process, APV is crushed to the material that is not more than 10 * 10 * 5mm.
Motor 1 drives reductor 2 and rotates, and reductor 2 drives coupler 3 and rotates, and coupler 3 drives the first axle 29 or the second axle 32 rotates, thereby therefore band moving blade 30 and blade 33 rotations are delivered to discharging opening 21 to APV from inlet point 6, and APV is carried out fragmentation.Clutch shaft bearing 4,19 pairs of screw shafts of the second bearing rise and support and fixation (avoiding swinging).
Hot blast enters outer chamber 37 from hot blast induction pipe 22 by the 3rd valve 23, conducts heat to the APV of inner cavity chamber's 36 interior conveyings by inner casing 24, and material is added moisture in heat abstraction APV.The hot blast that has heated enters bag dust collector 16 by hot-blast outlet pipe 26 through the second valve 14.The deaeration arm 35 of the moisture that the APV of inner cavity chamber 36 removes by cover plate 7 tops arrives except entering bag dust collector 16 after steam pipe 11 together with hot blast after heating emptying by induced draft fan 17.The hot blast temperature that enters bag dust collector 16 is controlled at 105～130 ℃.
