Bucket 6.The powder granule of discharge is sieved in the setting of material blanking tube 421, can sieve the excessive powder granule of diameter
It removes, since powder granule blanking relies on self gravity, the too small particle of diameter is since its own gravity is smaller, in hot wind and negative pressure
In the environment of will continue to upward ascension and be granulated, until reaching the standard of discharging.
As shown in Fig. 2, powder granule can block material blanking tube due to having little time discharging if the length of material blanking tube 421 is too short
421, influence the normal use of continuous spray granulator；If the length of material blanking tube 421 is too long, understands wasting space and can extend out
Expect the time, reduces production efficiency.Therefore, the length of material blanking tube 421 is set as dust trapping chamber 2, granulating chamber 3, spray chamber 4 and hot wind
For a quarter of the total height of mixing chamber 5 to one third, this unique design can either reduce what material blanking tube 421 was blocked
Possibility, and can be improved the discharging efficiency of powder granule.
As shown in Figure 1, granulating chamber 3 is in reverse frustoconic, the incline of granulating chamber 3 and the angle of axis are 15 ° to 30 °, this
Design advantageously reduces powder granule in the residual of 3 side wall of granulating chamber.
Specific implementation process: go out to be continually fed into hot wind in hot wind inlet 51, wet stock is become small by high-pressure atomization spray head 411
Spray chamber 4 is sprayed into after drop, droplet is with the upward ascension of hot wind, and with quick heat exchange, wet stock, which is realized, to be separated by solid-liquid separation,
Exhaust fan 211 extracts vapor by air outlet 21 out, and dust trapping chamber 2 is made to form negative pressure.
Powder granule be captured cloth bag 72 trapping, by 8 timing of pulse components to trapping cloth bag 72 be blown, make to adhere to
Powder granule on trapping cloth bag 72 sinks.Electromagnetic impulse valve 82 is opened by controller, and the compressed air in gas bag 81 enters
Injection tube 83 traps 72 center of cloth bag by blowing 831 directive of mouth, the powder granule for trapping 72 outer wall of cloth bag is shaken off.
During sinking, gluing is carried out again with wet stock and is granulated, keeps powder granule increasing, until powder
The self weight of particle is greater than upward wind-force, and powder granule drops to material blanking tube 421 under the effect of gravity, then, dry powder
Particle enters discharge bucket 6 by material blanking tube 421.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability
Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but
As long as all by the protection of Patent Law in the scope of the claims of the utility model.
