It is added inside to mixing drum 200, is conducive to subsequent different material mixing uniformity, improve mixing efficiency；
In suction material mechanism, according to Venturi tube principle, i.e., when air-flow passes through obstacle, in the backside gas of obstacle
Press it is lower, formed negative pressure, can generate gas flowing and suction-operated；When air enters powder suction tube 21 from main gas flow pipe 13
When, gap surrounding between main gas flow pipe 13 and powder suction tube 21 forms negative pressure so that the powder particles in tube for feed 100 from
Powder suction inlet 171 is inhaled into powder aspiration chamber 11, in addition, simultaneously, fluidisation gas-guide tube 15 is passed through into fluidisation air guide chamber 12
Partial fluidised air-flow, this partial fluidised air-flow are entered in powder aspiration chamber 11 by the second breather cloth 16, powder particles are blown afloat,
So that powder particles are in the suspended state of flowing, the ground powder particles that suspend form certain mixing ratio with air, can not
Disconnected to enter in powder suction tube 21, as air-flow enters inside adsorption mechanism 5 under the action of negative pressure, reasonable structural arrangement is inhaled
That expects is more efficient, and more energy saving, the ability for conveying powder particles is more preferable；21 outer cover of powder suction tube is equipped with powder gas cylinder
22, the bottom of powder gas cylinder 22 corresponds to powder suction inlet 171 and is extended with wide-mouth air scoop 222, extraneous during suction
Gas will necessarily be flowed by powder gas cylinder 22 into powder suction inlet 171, be further compensate for because suction generate low gas
Pressure, by the water conservancy diversion of wide-mouth air scoop 222, the material that air-flow will drive periphery is flowed into powder aspiration chamber 11, so that deep layer
The absorption of material is more smooth, avoids deep layer material excessively secret room and forms vacuum chamber, the extraction efficiency of powder is avoided to drop significantly
It is low.
