The utility model has the beneficial effects that：
A kind of powder delivery system of the utility model is shared a motor and is passed by more roots blower arranged in series
Dynamic, after the pressurization of excessive platform roots blower, the gas pressure intensity in conveyance conduit is equal to the pressure that more roots blowers are respectively increased
Summation, thus it is constant in conveyance conduit caliber and layout determination, and flow is constant to achieve the effect that supercharging, realizes very-long-range
Convey purpose.Since only with a motor drive, energy consumption is relatively low, can save conveying cost.
The preferred embodiment and advantage of the utility model, will be in conjunction with specific implementation mode further specifically
It is bright.
Description of the drawings
Attached drawing is to be used to provide a further understanding of the present invention, an and part for constitution instruction, and following
Specific implementation mode is used to explain the utility model together, but should not constitute limitations of the present invention.In the accompanying drawings,
Fig. 1：The structural schematic diagram of the utility model embodiment one of which powder delivery system.
The names of the parts and its label
1, motor；2, roots blower；3, conveyance conduit；4, non-return valve；5, belt transmission.
Specific implementation mode
Specific embodiment of the present utility model is described in detail below in conjunction with attached drawing.It should be understood that herein
Described specific implementation mode is only used for describing and explaining the present invention, and is not intended to limit the utility model.
It please refers to shown in Fig. 1, the embodiments of the present invention disclose a kind of powder delivery system, including 1 He of motor
More roots blowers are connected in series with by conveyance conduit 3 between the more roots blowers 2, and every roots blower 2
The conveyance conduit 3 of rear end is equipped with passes through one with 2 one-to-one non-return valve 4 of the roots blower, a motor 1
Set belt transmission 4 drives the more roots blowers 2 to operate.
Specifically, the present embodiment is to use two roots blowers 2 as the one of which specific embodiment party of the utility model
Formula is further described.A kind of powder delivery system of the present embodiment shares one by two 2 arranged in series of roots blower
Motor 1 is driven, and after two roots blowers 2 pressurize, constant in 3 caliber of conveyance conduit and layout determination, flow is not
Change achievees the effect that supercharging, realizes that very-long-range conveys purpose.Wherein, separate unit roots blower 2 provides the pressure of 0.09~0.1MPa,
Two series connection of roots blower 2 make pressure in conveyance conduit 3 reach 0.18~0.2Mpa or so.
Further include powder storehouse, batcher and screw conveyor, the powder storehouse connects the batcher, and the batcher connects
The screw conveyor is connect, the screw conveyor connects the conveyance conduit 3.Powder material, institute are housed in the powder storehouse
It can be coal dust or other powder body materials to state powder material, and the batcher is rigid impeller feeding machine.Powder passes through in powder storehouse
Cross rigid impeller feeding machine and screw conveyor discharging, powder strength after the abundant fluidization of screw conveyor discharge port with air-flow
It is pumped into conveyance conduit 3, completes very-long-range conveying.
The conveyance conduit 3 is set as tapered pipeline structure, and the reducing mode of the conveyance conduit 3 is：Backward from front end
Diameter is held to increase.Specifically, the conveyance conduit 3 divides for main pipeline, secondary pipeline, subtube etc., different tube diameters are respectively adopted, manage
Feed end gradually increases to discharge end without leave.If being used for pulverized coal conveying, the conveyance conduit for pulverized coal conveying is using thick
The caliber of wall seamless steel pipe, the conveyance conduit 3 can be determined according to coal dust conveying capacity, air velocity and material-gas ratio.Pulverized coal conveying
Pipe thickness can be determined according to the erosion to tube wall of the pressure and transported material material born, for being conveyed when coal dust material
The wall thickness of pipeline can use 4-8mm.Using tapered pipeline structure, power consumption and pipe wear can be not only reduced in this way, but also prevent from blocking up
Plug.
Further, the conveyance conduit 3 includes straight pipe and elbow section, the circular arc half where the axis of the elbow section
Diameter is equal to 10-15 times of the caliber of the straight pipe.The quantity that the elbow section should be reduced when specific design to the greatest extent, can both be reduced
The pressure loss and transducer wall's abrasion, and transmission failure caused by elbow blockage can be reduced.Since the total crushing of air-transport system is
It is made of 3 loss of total pressure of conveyance conduit, pipe outlet resistance, coal injection pipe resistance and pneumatic transport equipment resistance.Conveyance conduit 3
Loss of total pressure promotes resistance by horizontal straight tube section frictional resistance, vertical straight pipe frictional resistance and elbow section again and forms.For
Equigranular material, as elbow section R/D=6, equivalent length takes 8-10m；When elbow section R/D=10, equivalent length takes
10--16m；When elbow section R/D=20, equivalent length takes 12--20m.
Further include inert gas air supply system, the inert gas air supply system be the more roots blowers 2 provide into
Gas.In the case where fed distance is long, (>=200 meters) powder (coal dust) frictional impact between tube wall and coal dust and coal dust generates
Thermal energy, which reaches burning point, can lead to coal dust firing, therefore, use inert gas air supply system make the conveying gas in conveyance conduit 3 for
Inert gas and non-air can avoid the appearance of combustion phenomena.
In wherein another embodiment, spraying device is equipped in the conveyance conduit 3.Spraying device is to conveyance conduit
The interior temperature for spraying water mist for the powder for the conveyance conduit 3 that cools down and conveying gas reaches 3 inside temperature of cooling conveyance conduit
The purpose of degree can equally prevent the appearance of combustion phenomena in conveyance conduit 3.
Oil removal filter is equipped at the air outlet that the more roots blowers 2 are connect with the conveyance conduit 3.The oil removing
Filter filters remove tar or other greases contained in powder (coal dust), and preventing it from entering in conveyance conduit 3 influences
Laser propagation effect in powder.
In conclusion a kind of powder delivery system of the utility model is shared by more 2 arranged in series of roots blower
One motor 1 is driven, and after the pressurization of excessive platform roots blower 2, the gas pressure intensity in conveyance conduit 3 is equal to more roots blowers 2
The pressure summation being respectively increased, thus it is constant in 3 caliber of conveyance conduit and layout determination, and flow is constant to reach supercharging
Effect realizes that very-long-range conveys purpose.Due to being only driven with a motor 1, energy consumption is relatively low, can save conveying cost.
