Abstract
A venturi receives incoming material through an inlet tube and subjects the material to pulverization. The material, as it undergoes pulverization, is further subject to moisture extraction and drying. An airflow generator, coupled to the venturi, generates a high speed airflow to pull the material through the venturi and into an inlet aperture in the airflow generator. The airflow generator directs the received pulverized material to an outlet where the material may be subsequently separated from the air. An acoustic emission sensor receives the resonant frequencies generated by material passing through the airflow generator. The resonant frequencies reflect a material flow rate that is adjusted to avoid an overload situation. An automatic system coupled to an axle rotating the airflow generator to provide balance, improve efficiency, and eliminate cavitation.

Referring to Figure 13, shown the inside vertical view of a flow generator 500 with an independent blade.Shown that independent blade 510 illustrates the specific characteristic of blade 510 synthetic in flow generator 500.Remaining blade is specifically implemented similarly.
Referring to Figure 14 A, shown a more vertical view of detailed icon explanation wedge-like portion 516.The shape of wedge-like portion 516 has influenced throughput, air velocity and has passed through the flow of material of flow generator 500.Wedge-like portion 516 can change to change throughput, air velocity and flow of material at circumference and axial direction.Foundry engieering is convenient to allow to change at three dimension scale, and allows to have in wedge-like portion 516 any amount of circumference and longitudinal profiles.
The thickness of the increase of wedge-like portion 516 has prolonged the life-span of flow generator 500, stands the position of wearing and tearing at most usually because this is a blade 510.The remainder that material that wedge-like portion 516 is used and hardness also can be different from blade.
Referring to Figure 14 B, shown another embodiment of a wedge-like portion 518, this wedge-like portion 518 comprises an interchangeable wear tip 520.Along with flow generator 500 is rotated in a clockwise direction, interchangeable wear tip 520 has stood maximum material contacts.Although thickening strengthens wearability, wedge-like portion 518 has still stood more wearing and tearing than other assembly of flow generator 500, and may damage quickly.By replacing interchangeable wear tip 520, postponed the replacement of whole flow generator 500.By any known fixture, comprise a hold-down nut and bolt assembly 522, interchangeable wear tip 520 is connected to the remainder of wedge-like portion 518.Interchangeable wear tip 520 can be a material harder than the remainder of blade.Interchangeable wear tip 520 also can be had an interchangeable wear tip 520 of different circumference and axial profile and be replaced.In another embodiment, whole wedge-like portion 518 is interchangeable.

Angled position has one and is called the angle of the angle of attack at this, because the air-flow that its allows guide margin 514 incisions to introduce.In Figure 13, the final angle of attack of blade on guide margin 514 is about 25 degree.Can extend across whole blade 510 or its any part from the transition of angled position, a upright position to.Can from a large-scale angle, select the angle of attack based on expection air velocity, flow of material and material.Angled position can have a scope of about 20 to 60 degree.
Selectively, blade 510 can keep vertical along its whole length.Blade 510 also can have an angle of attack along its whole length.Although extend along whole length, when blade 510 from guide margin 512 to lagging edge 514 when extending, the angle of attack may still change.
Referring to Figure 16, shown a profile diagram of guide margin 514.Traditionally, can be more straight and advance on an angle with respect to back plate 506 in an edge.In one embodiment of this invention, guide margin 514 along with a bandy part 528 is advanced, transits to an inside curve 530 from back plate 506 then.Bandy part 528 helps the air of the input hole 504 that catching advances enters flow generator 500.The guide margin 514 of profile can be cut air and improve the efficient of flow generator 500 like this.
Referring to Figure 17, shown the cross section of guide margin 514 along cross section 17-17.Guide margin 514 has a plurality of stepped serrations of the air-flow that helps the incision introducing.
Referring to Figure 18, shown a stereogram of flow generator 500, this flow generator 500 does not have header board 502 to illustrate blade 510.Although the quantity of blade is variable, shown embodiment comprises nine blades 510.Each blade 510 comprises a wedge-like portion 516, is used to strengthen wearability and increases pressure and air-flow.Each blade 510 further transits to an angle of attack from a upright position.The angle of attack tilts to the clockwise orientation that rotates corresponding to the expection of flow generator 500.Flow generator 500 can move along counterclockwise orientation, and this blade 510 should tilt to that direction.
Be in operation, the blade 510 of rotation has produced from 350mph or to a bigger high velocity air, and air and comminution of material are introduced input hole 504.The guide margin 514 incision air and the comminution of material of blade 510, and with air and comminution of material introduce 510 that limits by blade, extend to the header board and the back flow path 532 of the periphery 513 of plate 502,506 from input hole 504.Flow path 532 can have a maximum stream flow for the material that passes through.Wedge-like portion 516 is pushed to the housing outlet 202 that is arranged in shell 200 with air and comminution of material.Although flow generator 500 provides unique feature, one of skill in the art will recognize that and to use any amount of device, and these devices are included in the scope of the present invention.
