Technical field
It the utility model is related to a kind of dry method material fining crushing and classification equipment, especially a kind of fluid bed airflow milling point
Level machine.
Background technology
The principle of fluidized bed jet mill grader is that lower part is that the nozzle being oppositely arranged makes for discharging supersonic airstream
Material is opposite to be collided, and material is in fluidized state in the cavity, while the adjustable high speed of speed rotates grading wheel, produces centrifugal force
, when the Dual-Phrase Distribution of Gas olid after guiding crushing is moved by grading wheel impeller clearance ecto-entad, particle is forced in centrifugal force
Do in and rotate at a high speed, larger particle is thrown toward shell under the action of powerful centrifugal force, and under the effect of gravity, is deposited to
Crushing chamber continues to crush, and smaller particle then under the action of gas drag, moves to internal rotor with air-flow, becomes qualified products
Cyclone collector is entered by pipeline.The characteristics of its effectiveness of classification is higher, and host can be isolated in time by reaching the particle of fineness,
But the most efficiency of fluidized bed airflow pulverizer that uses at present is low, high energy consumption, crosses that crushing phenomenon is more serious, and main cause is
Finished product after crushing cannot collect in time, it is uneven etc. to feed.
In order to solve the above-mentioned technical problem, applicants have invented a kind of fluidized bed jet mill grader, including crushing chamber,

Fast nozzle；The crushing chamber bottom is provided with the taper collection hopper extended into distribution of air flow room；The collection hopper bottom is set
There is the communicating pipe for extending gas distribution chamber；The communicating pipe lower end is provided with clout collection port.
As an improvement overfiren air port is provided with above superonic flow nozzzle on the crushing chamber side wall.To crushing
Intracavitary provides Secondary Air, and the qualified material that can make to be mixed in unqualified material is blown to grader, so as to be sucked out, is avoided
Qualified material drops back into crushing chamber and crosses crushing again, pulverizer is improved crush efficiency and yield, while reduce energy consumption.
As an improvement it is provided with silencer on the high-pressure suction fan.Make an uproar for eliminate that high-pressure suction fan brings
Sound, more healthy working environment is provided for operator.
As a preferred embodiment, the deduster is chamber off-line ash cleaning and dust removing device.Its performance is passed better than cyclone separator etc.
System deduster.
As an improvement Hand-operated butterfly valve is installed in the clout collection port.For opening and closing clout collection port.
As a preferred embodiment, the superonic flow nozzzle be along crushing chamber even circumferential distribution several so that Suo Youchao
The jet stream that sonic nozzle ejects is zero in the sum of velocity of convergence center point.
Automatically adjusted as an improvement the feed spiral device is carried out with grader current fluctuation.If classification is electromechanical
Stream is high, and feed spiral device is just automatic to reduce inlet amount, if grader electric current is less than specified standards, feed spiral device is with regard to automatic
Inlet amount is increased, automated control inlet amount remains an equilibrium state.
The utility model is beneficial in that：Fluidized bed jet mill grader with said structure, its crushing chamber
The collection hopper of bottom extends into gas distribution chamber so that its clout collection port extends to gas distribution chamber bottom through gas distribution chamber
Portion.The more convenient arrangement other equipment of operator is allowed to be used to collect clout.In addition above-mentioned setting make it that equipment is compacter easily
Dismounting, while bottom material is convenient for changing, and gas pressure loss reduces.
