Body, fluid and the return tank 17 of spiral flow direction form the effect similar to cyclone separator, make gas solid separation, and gas band dampening is steamed
Steam flow goes out, and powder is fallen in drier internal circulation flow;
The top of return-air tank 12 is provided with muffler 15, and muffler 15 is nested in outside Venturi tube 18, return-air tank 12
Diameter change at cause flowing air pressure change, the effect of similar cyclone separator is formed to fluid with spiral, make gas-solid divide
From more thoroughly, gas flows out with caused vapor after heat exchange, and powder is in drier internal circulation flow;The return-air tank
Vacuum-pumping tube 16 is also equipped with 12;
Above-mentioned return-air tank frustum cone structure and the side of return tank frustum cone structure and the angle of horizontal direction are all higher than drying
The angle of friction of powder, and the side of taper closing in of the tapered side of the sealing piston 7, discharge nozzle and the angle of horizontal direction
Also it is all higher than the angle of friction of dried material.So setting can be such that powder is slided along inclined side, will not rest on powder
The surface of inclined side.
The junction of above-mentioned all ring flanges is equipped with sealing device.
Further characteristic of the invention is that the quantity of the venturi branch pipe 10 is the six roots of sensation, powder can be made to prolong text well
Branch pipe is flowed back in Venturi tube 18 in mound.
Further characteristic of the invention is at the axial line horizontal cross-section of whirlwind escape pipe 14 (referring to Fig. 2), return-air tank
The sectional area formed between 12 and return tank 17 is Formation cross-section accumulates between return tank 17 and air-flow tank epimere 11 three to six times,
Formation cross-section product is that Formation cross-section accumulates between air-flow tank epimere 11 and Venturi tube 18 between return tank 17 and air-flow tank epimere 11
Three to six times;To make fluid, speed constantly reduces in flow process, makes gas solid separation, so that gas is with heat
Caused vapor discharge, powder constantly circulate in drier after exchange.
The Venturi tube of the application is first tapered into the bottom become larger again and formed by the top and diameter of cylinder, on
The length in portion is more than the length of air-flow tank epimere 11, and passes the upper end of air-flow tank epimere 11, and bottom diminishes initial in diameter
Opening position uniformly installs more venturi branch pipes 10, and more venturi branch pipes are big with horizontal plane certain angle, the angle
In the angle of friction of dried material, venturi branch pipe and the mutual UNICOM of Venturi tube, air-flow pass through the initial position that the diameter diminishes
Place, air-flow from the coarse to fine, accelerate gas flow rate, gas is formed in the rear side of Venturi exit (i.e. the lower end of Venturi tube)
One " vacuum " area, absorption affinity can be produced by this " vacuum " area, material is entered the region of no pressure along venturi branch pipe.
The operation principle and workflow of drier of the present invention be:
1) feed
Sealing piston 7 is sealed the lower port of air-flow tank hypomere 19, fed from charge pipe 13, according to the aobvious of weighing device 8
Show, add a certain amount of powder to be dried, be then shut off charge pipe 13.
2) vacuumize
Charge pipe 13 is kept to close, the upper end for closing Venturi tube 18 is the draught damper of air inlet connection, closes muffler
The draught damper of 15 connections, the draught damper that vacuum-pumping tube 16 connects is opened, according to the difference of powder, vacuum is determined, works as vacuum
When reaching certain value, the draught damper that vacuum exhaust pipe 16 connects is closed.Under vacuum, the water in hydrate is easier to separate out, and water
Easily vaporize.Kept for a period of time.
3) powder cyclic drying
The draught damper of the upper end of Venturi tube 18 connection is opened, opens the draught damper that muffler 15 connects.From Venturi tube 18
Upper end starts to be blown into hot nitrogen into drier, after the outflow of the lower end of hot nitrogen flow through venturi 18, into air-flow tank, by air-flow tank
In powder blow floating, fluid in flow process fully carry out heat exchange, the moisture in powder is become water vapour, then
Whirlwind escape pipe 14 of the fluid through air-flow tank epimere 11 is blown out, formed spiral to fluid, and with the frustum cone structure of return tank 17
The effect similar to cyclone separator is formed, makes the flow velocity of fluid reduce, gas solid separation, powder is fallen, into next circulation,
Gas continues to flow with vapor, when fluid enters return-air tank 12, spiral to fluid form similar rotation with return-air tank 12
The effect of wind separator, flow velocity are further reduced, and carry out gas solid separation again, and powder is fallen, into next circulation, gas
Discharged with vapor by muffler 15.
Due to Venturi tube 18 lower diameter change, make pipe attenuate place flow velocity accelerate, pressure reduce, to venturi branch pipe
Attractive effect at 10, the powder in return-air tank 12 is under self gravitation and the suction of Venturi tube 18 through venturi
Branch pipe 10, the inflow stream tank of Venturi tube 18, carry out next circulation.
Further, since each tube layer layer nesting of drier, i.e. return-air tank, return tank, air-flow tank and Venturi tube are from outside to inside
It is nested successively, the fluid heat between each pipe is interacted, accelerate the drying of powder.After hot gas heats each tube wall, each layer pipe
Wall radiations heat energy, it can also accelerate the drying of powder.
4) blanking
When detecting that humidity is up to standard at muffler 15, the draught damper of the upper end of Venturi tube 18 connection is closed, stops drying.
Start the motor of feed screw 2, then move down cylinder 5, drive sealing piston 7 to move down, dry powder warp
Material blanking tube 4, feed screw 2 drop out.
The not described part of the present invention is applied to prior art.
