Technical field
This utility model is related to a kind of wood powder dose delivery system.
Background technology
At present, for some the wood powder combustors on market, maximum failure all goes out in wood powder conveying, and many enterprises are all
Using conical hopper, it is particularly easy to put up a bridge, does not go under wood powder, wood powder conveying is interrupted, causes combustor cutoff, conical lower portion to hold
Wood powder caking is easily caused, is caused wind to send difficult and furnace puff phenomenon, is often blocked duff pipe, lead to not use.Also
A little enterprises air-introduced machine is inhaled powder and sends into combustor, and this mode easily causes fan blade and is damaged, and increased maintenance rate.Wood powder supply
And powder feeding Boiler pressure control is inaccurate or uncontrollable, the phenomenon of detonation and over-emitting black exhaust is caused.
Utility model content
For drawbacks described above, the purpose of this utility model is to provide a kind of wood powder conveying uniform, is difficult to interrupt, maintenance rate
It is low, long service life, a kind of safe wood powder dose delivery system.
The technical scheme adopted by this this utility model is：
Including storage bin, feeding warehouse, oblique screw rod, separator and venturi, the storage bin is rectangle structure, storage bin
For open, the oblique screw rod is inclined and mounted on storage bin lower end open-mouth for lower end, is connected with and turns over below the high-end place of the oblique screw rod
Plate valve, the separator are arranged on storage bin upper end, and separator is located at the top of oblique screw rod low side, the venturi rear end connection
The air inlet for having aerator, the aerator is connected with feeding warehouse upper end by air-suction duct, and the separator upper end is by row
Smoke pipe is connected with air-suction duct, and the separator sidewall is provided with feed pipe, the other end and feeding warehouse of the feed pipe
Lower end connects, and the oblique screw rod is controlled using frequency conversion motor.
Used as the further improvement of above-mentioned technical proposal, the smoke exhaust pipe is provided with the first air pump, and first air pump is leaned on
Nearly air-suction duct.
Used as the further improvement of above-mentioned technical proposal, the separator lower end is provided with the discharge valve being connected with storage bin.
Used as the further improvement of above-mentioned technical proposal, the lower end of the feeding warehouse is funneling.
Used as the further improvement of above-mentioned technical proposal, the feed pipe is provided with the second air pump, second air pump
Near feeding warehouse lower end.
The utility model has the advantages that：
This utility model simple structure, by adopting oblique screw rod transmission wood powder, and controls oblique screw rod using frequency conversion motor, can
Wood powder conveying capacity is controlled accurately；The wood powder of caking can be smashed by flap valve, reach the uniform purpose of wood powder, be easy to wind-force defeated
Send；Venturi is installed in flap valve lower end, makes powder no longer block delivery pipe, reduces maintenance rate；It is safe.
