Such as Fig. 1, Fig. 2, shown in Figure 3: a kind of construction parameter adjustable blade formula throws device, and it comprises paddle shaft 1, throws impeller 2, circle throws shell 3, discharging straight tube 4 and deflection bend pipe 5; Paddle shaft 1 and throw impeller 2 and all be installed on circle and throw in the shell 3; Discharging straight tube 4 is installed on circle and throws shell 3 tops; Deflection bend pipe 5 is installed on the top of discharging straight tube 4; Throw impeller 2 and comprise that throwing frame plate 7 and four throws blade 8; Throwing blade 8 is fixed in by bolt and throws on the frame plate 7; The lower end, the place ahead that circle throws shell also has spout 6;
Throwing blade 8 is four;
Discharging straight tube 4 throws between the shell 3 with circle and is connected by annular iron plate;
Be connected by annular iron plate between deflection bend pipe 5 and the discharging straight tube 4;
The external arc radius of curvature R 1 of deflection bend pipe 5 is greater than the external diameter that throws impeller 2.
The inclination angle of anteversion and retroversion blade namely throws blade 8 stagger angles, refers to recede or turn forward with respect to throwing the identical radial vane of impeller 2 external diameters; Backward still forward for impeller turns to, as shown in Figure 4.The blade that throws of the present utility model can be radial vane (such as Fig. 4 c) and anteversion and retroversion blade, and the inclination angle of anteversion and retroversion blade can leaned forward 25 °, 20 °, 15 °, 10 °, 5 ° (such as Fig. 4 a); Adjust in the hypsokinesis 25 °, 20 °, 15 °, 10 °, 5 ° (such as Fig. 4 b).Mainly make up as shown in Figure 5 in twos by the different holes that throw on the frame plate 7.Among the accompanying drawing 5a radial vane can be installed; With angle radially be that the anteversion and retroversion blade of 5 ° of hypsokinesis can be installed in 41 ° two holes, with respect to axisymmetric two holes of level 5 ° the anteversion and retroversion blade of leaning forward can be installed with it; It is after 57 ° two holes can be installed with angle radially in like manner or 10 ° the anteversion and retroversion blade of leaning forward.Among the accompanying drawing 5b, with angle radially be after 49 °, 67 °, 88 ° two holes can be installed respectively or 15 °, 20 °, 25 ° the anteversion and retroversion blade of leaning forward.
Can be divided into three phases when the utility model throws material: F/s is that the impeller 2 that throws of High Rotation Speed is tossed the material stage.In this stage since the suffered centnifugal force of material greater than the suffered centnifugal force of air-flow, so air-flow is less to the effect of material, material mainly tosses to obtain energy by the blade 8 that throws of High Rotation Speed.Subordinate phase is that material leaves and flows through 4 stages of discharging straight tube after throwing blade 8.High Rotation Speed throw blade 8 in the material of tossing, also make air-flow obtain energy and assist convey materials 4 sections of discharging straight tubes.The phase III material leaves behind the discharging straight tube 4 and the collision of deflection bend pipe 5 outer arc walls, then under centrifugal action with burbling, along the outer arc wall slip up to leaving the utility model.
The blade 8 that throws of present embodiment is four, to the utility model research experiment as can be known, adopts quaterfoil more to be conducive to material throwing than three blades and five blades, and for the impeller of High Rotation Speed, quaterfoil more is conducive to kinetic balance, and therefore, it is four that present embodiment is selected the number of blade.
Blade dimensions of the present utility model is capable of regulating also, just with to throw two pitch-rows that frame plate 7 is bolted constant, adapting to different impeller outer diameters and width requirement, mates with agricultural fibrous materials results and the processing equipment of different model size.
What the circular housing outlet that throws device of prior art and discharging straight tube 4 junctions had is transition arc (transition arc radius varies), and what have is wedge angle.By material movement law is carried out numerical modelling and high-speed camera experimental investigation as can be known, adopt wedge angle and excessive transition arc radius all to be unfavorable for material throwing.Adopt wedge angle that the resistance of material and air-flow is increased, result in blockage easily; Adopt excessive transition arc radius that gas is circulated in the enclosure.Therefore present embodiment adopts shell transition arc radius r=20mm, as shown in Figure 6.
