Description

The rotating nozzle type air flow crushing device
Technical field
The utility model relates to a kind of reducing mechanism, specifically a kind of rotating nozzle type air flow crushing device that is applicable to various graininess powder products such as processing carborundum, aluminium oxide.
Background technology
We know that powder products such as carborundum, aluminium oxide have a wide range of applications in various fields such as abrasive material, grinding tool, cutter, iron and steel industry, nonferrous metallurgy, silicate, chemicals.At present, the process equipment of powder product is based on the fluidized bed type airslide disintegrating mill both at home and abroad, and this machine is made up of reducing mechanism, grading plant two large divisions.The operation principle of reducing mechanism is, by nozzle 0.6~0.8MPa compressed air is converted into high velocity air, quickens particle and also makes it to produce mutual collision, thereby reach the purpose that reduces grain graininess.Traditional fluidized bed type airslide disintegrating mill reducing mechanism adopts fixed nozzle formula structure, nozzle and pulverizing chamber are transfixion, pulverize in the process at particle, easily form the part dead band, pile up material, not only reduce crush efficiency, increased energy consumption, and increased the probability that undesirable product is sneaked into finished product.
Summary of the invention
The utility model is for overcoming above-mentioned the deficiencies in the prior art, and providing a kind of can significantly increase effective crushed work zone, reduces the dead band of pulverizing chamber inside, improves the collision probability of particle, improves crush efficiency, the rotating nozzle type air flow crushing device that cuts down the consumption of energy.
The purpose of this utility model is to adopt following technical proposals to realize:
A kind of rotating nozzle type air flow crushing device, comprise pulverizing chamber, nozzle and stationary magazine creel, the pulverizing chamber sidewall is located in the stationary magazine creel by bearing, the pulverizing chamber bottom is connected with the rotating drive shaft that passes the stationary magazine creel bottom, the cylindrical shell circumferencial direction of pulverizing chamber is evenly distributed with at least one pair of nozzle, pulverizing chamber top is connected with the airflow classification device connector, and stationary magazine creel is provided with air inlet.
Bearing between pulverizing chamber outer wall and stationary magazine creel inwall is respectively equipped with sealing device up and down.
Described pulverizing chamber is connected with the grading plant connector by rubber liner.
Between pulverizing chamber bottom and the stationary magazine creel bottom compressed air cell is arranged.
On the airflow classification device connector, be provided with feeding mouth.
Rotating drive shaft is located on the stationary magazine creel by supporting mechanism.
The utility model is on the close sidewall of bottom of tubular pulverizing chamber, along the circumferential direction be evenly distributed with at least one pair of nozzle, driving pulverizing chamber by power set and power transmission shaft rotates with nozzle, form the high velocity air of rotation when making reducing mechanism work, thereby the dead band, flow field in the minimizing pulverizing chamber, increase the collision probability of material, improve crush efficiency, cut down the consumption of energy.

The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Among Fig. 1, pulverizing chamber 7 sidewalls are located in the stationary magazine creel 13 by bearing 6, pulverizing chamber 7 bottoms are connected with the rotating drive shaft 11 that passes stationary magazine creel 13 bottoms, the cylindrical shell circumferencial direction of pulverizing chamber 7 is evenly distributed with at least one pair of nozzle 8, pulverizing chamber 7 tops are connected with airflow classification device connector 1 with screw 4 by rubber liner 3, and stationary magazine creel 13 is provided with compressed air inlet port 12.Bearing 6 between pulverizing chamber 7 outer walls and stationary magazine creel 13 inwalls is respectively equipped with sealing device 5 up and down.Between pulverizing chamber 7 bottoms and stationary magazine creel 13 bottoms compressed air cell 9 is arranged.On airflow classification device connector 1, be provided with feeding mouth 2.Rotating drive shaft 11 is located on the stationary magazine creel 13 by supporting mechanism 10.
During work, the clean compressed air of 0.6~0.8MPa enters into compressed air cell 9 by air inlet 12, by being installed in rotation many to along the equally distributed nozzle 8 of cylindrical shell circumferencial direction on the pulverizing chamber 7, compressed air is converted into high velocity air.Granular material utilizes self gravitation to drop in the rotation pulverizing chamber 7 by feeding mouth 2, near nozzle 8 positions, quickens and produces collision mutually by high velocity air, thereby reach the purpose of particle pulverizing.The particle that has reached granularity requirements sieves by the airflow classification device that links with airflow classification device connector 1, shifts out the working region, and the relative ground of grading plant is inactive state.Power set drive pulverizing chamber 7 and nozzle 8 rotations by rotating drive shaft 11, form the high velocity air of rotation, can effectively reduce the dead band in the pulverizing chamber.5 pairs of compressed air cells 9 of labyrinth-type excluder seal, and do not produce loss with the pressure that guarantees the chamber compressed air, and guarantee that particle can not leak into bearing 6 places.Because there is the pressure about 0.2MPa in pulverizing chamber 7 inside, pulverizing chamber 7 and grading plant are partly located and can be formed sealing by the pressure differential between inside and outside.
