Abstract

The invention discloses an airflow crushing device of a fluidized bed. The device comprises a supporting base and a body. A grading cavity, a crushing cavity, a raw material feed inlet, a raw material discharging port, a compressed air annular pipe and high-pressure nozzles are arranged on the body. The compressed air annular pipe surrounds the body of the airflow crushing device of the fluidized bed and is connected with the high-pressure nozzles of the airflow crushing device of the fluidized bed through a guide pipe. The airflow crushing device has the advantages of being short in crushing time, simple in structure, low in noise and free of vibration, and is low in energy consumption. Compared with airflow grinding of other types, energy can be saved by one third.

Description

A kind of fluidized bed air flow crushing device
Technical field
The present invention relates to material-pulverizing device, particularly relate to a kind of fluidized bed air flow crushing device.
Background technology
Fluid bed airflow milling realizes the fine equipment of dry type material fining with high velocity air, is widely used in mineral products, chemical industry, electronics, the fields such as agricultural chemicals.
When external high pressure air, by high pressure nozzle to pulverizing chamber jet-stream wind, material reaches pulverizing after being subject to air-flow repeated stock head-on collision, pulverizes fine particle material along with ascending air and enters grading room, and fine particle enters cyclone separator along with air-flow, trap is collected, complete crushing process, corase particles returns pulverizing chamber and continues impact comminution, and the particle that traditional fluidized bed plant obtains exists uneven, and complex structure, inconvenient operation.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of fluidized bed air flow crushing device, can crush efficiency high, can pulverize continuously, and keep pulverizing goods purity.
For solving the problems of the technologies described above, described fluidized bed air flow crushing device comprises supports base and body, body is provided with graded chamber, pulverizes cavity, raw materials mouth, raw material discharging opening, compressed air goes in ring pipe, high pressure nozzle, and described compressed air goes in ring the body of circumference of cannon bone around fluidized bed air flow crushing device, by the high pressure nozzle of tubes connection fluidized bed air flow crusher
A kind of optimal technical scheme, described high pressure nozzle quantity is 4 to 9 nozzles, and nozzle is positioned at pulverizes cavity, operation, and high pressure nozzle is to pulverizing cavity inject high pressure supersonic airstream.
Described raw materials mouth is positioned at pulverizes cavity upper end, and material enters pulverizing cavity by raw materials mouth, and high pressure supersonic airstream sprays intersection repeated stock, and crushing material, pulverized material enters graded chamber along with ascending air,
Graded chamber upper end outer wall is provided with classification drive motors, and grading wheel, grading wheel is High Rotation Speed under drive motors drives, produce centrifugal force, at this time material particle had both been subject to the centrifugal force that grading rotor produces, and was subject to again the centripetal force that air-flow viscous effect produces, when particle be subject to centrifugal force be less than centripetal force when, corase particles returns pulverizing chamber and continues impact comminution, and finished particle can be discharged from raw material discharging opening along with air-flow, enters the devices such as separator.
In order to control compressed-air actuated temperature, air heater can be connected at the compressed air pipe that goes in ring, controlling the temperature of high pressure compressed gas.
A kind of optimal technical scheme, for the ease of detecting the problem of high pressure compressed gas, is provided with temperature-detecting device on compressed air goes in ring pipeline.
The invention has the beneficial effects as follows: it is short that the present invention has grinding time, structure is simple, and operation maintenance is convenient, and floor space is little, low noise and vibrationless advantage, and energy consumption is low, compared with the Gas grinding of other type, and energy energy-conservation 1/3rd.
Accompanying drawing explanation
Fig. 1 is a kind of airflow crushing system of fluidized bed structural representation of the present invention;
In accompanying drawing, the mark of each parts is as follows:
1 is graded chamber, and 2 for pulverizing cavity, and 3 is raw materials mouth, and 4 manage for compressed air goes in ring, and 5 is material outlet, and 6 is high pressure nozzle, and 7 for supporting base, and 8 is classification drive motors, and 9 is grading wheel.

Refer to Fig. 1, the embodiment of the present invention comprises:
Fluidized bed air flow crushing device comprises supports base and body, body is provided with graded chamber, pulverizes cavity, raw materials mouth, raw material discharging opening, compressed air goes in ring and manages, high pressure nozzle, described compressed air goes in ring the body of circumference of cannon bone around fluidized bed air flow crushing device, by the high pressure nozzle of tubes connection fluidized bed air flow crusher, described high pressure nozzle quantity is 4 nozzles, and nozzle is positioned at pulverizes cavity, operation, high pressure nozzle is to pulverizing cavity inject high pressure supersonic airstream.
Described raw materials mouth is positioned at pulverizes cavity upper end, and material enters pulverizing cavity by raw materials mouth, and high pressure supersonic airstream sprays intersection repeated stock, and crushing material, pulverized material enters graded chamber along with ascending air.
Graded chamber upper end outer wall is provided with classification drive motors, and grading wheel, grading wheel is High Rotation Speed under drive motors drives, produce centrifugal force, at this time material particle had both been subject to the centrifugal force that grading rotor produces, and was subject to again the centripetal force that air-flow viscous effect produces, when particle be subject to centrifugal force be less than centripetal force when, corase particles returns pulverizing chamber and continues impact comminution, and finished particle can be discharged from raw material discharging opening along with air-flow, enters the devices such as separator.
In order to control compressed-air actuated temperature, air heater can be connected at the compressed air pipe that goes in ring, controlling the temperature of high pressure compressed gas.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
