Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing.
As shown in Figure 1, a kind of powder transport device of the utility model comprising one is used to collect, keeps in powder
Aggregate bin 1, the top import of aggregate bin 1 are equipped with the first electric butterfly valve 2 that control aggregate bin is opened, and the bottom end outlet of aggregate bin is set
The second electric butterfly valve 3 for having control aggregate bin to close, the bottom end outlet of aggregate bin are connected to the powder of storage bin 11 through conveying pipeline
Entrance, conveying pipeline are equipped with one or more (such as 2 or 3) air knife valve (9,10) to push powder Forward, air knife valve
The air inlet of (9,10) and one end of appendix connect, and the other end of appendix is through being connected to gas source pipe after impulse electromagnetic valve 5
Road (B), each air knife valve are equipped with what an air-flow for controlling the air knife valve entered on the appendix of its airintake direction
Ball valve (7,8), the outlet at bottom of storage bin are equipped with the Hand-operated butterfly valve 13 that control powder is released.
Aggregate bin lower end is connect with one end of loose metal tracheae 6, and the other end of loose metal tracheae 6 is passed through for controlling gas disengaging collection
Gas source pipe is connected to after the loose metal solenoid valve 4 of hopper.
At least two (such as 2 or 3 or 4) air knife valves are preferably provided on conveying pipeline, each air knife valve is individually matched
Have an appendix and a ball valve, between each ball valve by appendix it is parallel with one another after summarize and be connected to impulse electromagnetic valve, passages through which vital energy circulates
It rushes solenoid valve and gas source pipe is connected.
As shown in Fig. 2, the air knife valve is stainless steel material, consisting of bilayer sleeve, inner tube is circular pipe, inner tube
It is seamlessly connected with conveying pipeline, the outer surface of outer tube and inner tube forms confined space, and appendix and outer tube are seamlessly connected, are located at closed
Around the equally distributed round gas hole 15 of setting on inner pipe wall in space.
The round gas hole 15 of air knife valve inner pipe wall is distributed as 1-10 row/column, every row/column 1-15, preferably 1-5
Row/column, every row/column 1-10, the inclination angle that gas hole is biased to powder transporting direction is 40-75 ° of angle, preferably 50-70 ° of angle.
Storage bin top export is equipped with the filter 12 being filtered to fuel gas and dust unsegregated after conveying.
Storage bin is located on bracket 14.
Aggregate bin 1 is closed rustless steel container, and shape is middle circle tubular, both sides taper, and storage bin shape is top
Cylinder-shaped, lower section back taper.
In one embodiment, using two air knife valves, two ball valves are corresponded to, the circle of air knife valve inner pipe wall is blown
Gas cell distribution is 5 rows/column, and every row/column 10, the inclination angle that gas hole is biased to powder transporting direction is 65 ° of angles.It is practical using this
Novel device carries out the process of powder transport are as follows:
As shown in Figure 1, firstly, open the first electric butterfly valve 2, and by the second electric butterfly valve close 3, then again by powder thing
Material is launched from A point to be entered in aggregate bin, until closing the first electric butterfly valve 2, while again making the second electric butterfly valve after certain amount
3 are opened, material starts to move downward under the effect of gravity and enters conveying pipeline at this time；
Then, open loose metal solenoid valve 4, conveying inert gas (generally nitrogen) through loose metal solenoid valve 4, loose metal pipe 6 into
Enter 1 inside of aggregate bin and increase the pressure in aggregate bin, powder in aggregate bin 1 is further pressed downward into feeding pipe and gas
In knife valve 9, air knife valve 10, further due to the presence of loose metal pipe 6, the pressure inside aggregate bin 1 can be effectively balanced, is prevented
Only negative pressure influences and causes to get stuck, meanwhile, conveying gas is entered below aggregate bin 1 by loose metal pipe 6, moreover it is possible to play bulk material
Effect；
Again, impulse electromagnetic valve 5 and ball valve 7, ball valve 8 are opened, air pulse is allowed to respectively enter air knife through ball valve 7, ball valve 8
In valve 9 and air knife valve 10, two air knife valves are started to work, and it is circular pipe that due to air knife valve, it is internal, are surrounded in pipeline
The round gas hole of multiple inclinations angle (tilt angle is 65 °), air pulse, can be effective by being blown into inclined gas hole note
Powder material is pushed to move to direction initialization, in which: after migrating forward with the powder in air knife valve 9, sky is released in valve
Between, pressure becomes smaller, and the material in rear aggregate bin 1 is moved forward successively by the effect of pressure and the dual power of gravity and fills up air knife valve
In 9；Likewise, being transported to the powder in air knife valve 10, equally continued to move ahead by 10 air pulse thrust of air knife valve, until will
Powder conveying is final to realize being continuously conveyed for powder into storage bin 11；
Finally, by gravity major part sedimentation separation, unsegregated fuel gas and dust is by mistake after powder is sent into storage bin 11
Filter 12 filters, and filtered gas is discharged from feed bin and recycles (arrow C in figure), and the powder being collected by filtration then falls into storage bin
In 11, when discharging, the outer wall of mallet rapping storage bin 11 can be used, storehouse inner wall and surrounding powder is made to fall into orlop, opens hand adjustment
13 blowing of valve carries out follow-up work (D in figure).
The utility model also has the function of preventing powder from blocking simultaneously, and powder generally in gentle conveying section and rises conveying
Section is easy to happen blocking, and multiple air knife valves, which are arranged, can increase powder carry power, prevents powder from rising transport section blocking；And
If the gentle blocking between two adjacent air knife valves occurs for powder blocking, at this point, need to only close the latter air knife valve
To increase the air-blowing quantity of previous air knife valve to wash the powder of blocking open.
