Sensor is also electrically connected the feedback controller.
It is preferably located at and alters the connection pipe outer wall top of side on gas and be fixedly connected and alter side institute in regulating gas
State the air pressure regulator of connection intraductal atmospheric pressure.
Preferably, filter device is provided on the air pressure regulator.
Preferably, the angle between the connection inside pipe wall and the deflector is 45 degree.
Preferably, the middle part of the gas powder demarcation plate is arranged in the impulse sensor.
The utility model has the following advantages that due to taking above technical scheme：1, the utility model is due to connecting
It is provided with gas powder demarcation plate in pipe, connecting tube is divided on gas and alters two separate spaces in side and powder thrown wall, it is significantly slow
Interference of the upper gas blowby body to powder flowing is solved, structure is simple, easy to operate and cost of manufacture is cheap.2, the utility model is even
It is provided with deflector in adapter tube, is collided when powder falls through deflector and gas powder demarcation plate, is capable of forming continuous side wall stream, foot
To resist interference of the upper gas blowby body to the flowing of powder whereabouts.3, the utility model is due to being provided with impulse sensor and feedback control
Device can be realized the quantitative to powder of device, while also for powder is stable, quantitatively conveying provides the foundation of automatic control.4, this reality
With novel due to being provided with air pressure regulator, when altering that the gas flow accumulated in side is excessive, air pressure is excessively high on the gas of connecting tube,
Gas can be discharged by opening air pressure regulator, improve the stability of powder conveying, can be widely applied to the energy, change
In the technical fields such as work and building materials.
Detailed description of the invention
Fig. 1 be in the prior art double back rotary valve structure to the structural schematic diagram of powder device；
Fig. 2 is the quantitative structural schematic diagram to powder device of the utility model.
Specific embodiment
Come to carry out detailed description to the utility model below in conjunction with attached drawing.It should be appreciated, however, that attached drawing is provided only
More fully understand the utility model, they should not be interpreted as limitations of the present invention.
As shown in Fig. 2, quantifying to powder device based on double back rotary valve structure provided by the utility model includes last time rotary valve
1, lower revolving valve 2, connecting tube 3, gas powder demarcation plate 4, deflector 5, air pressure regulator 6, impulse sensor 7 and feedback controller
(not shown), wherein be provided with filter device on air pressure regulator 6.
The outlet at bottom of last time rotary valve 1 connects the top inlet of lower revolving valve 2 by connecting tube 3, axially inserts in connecting tube 3
