Summary of the invention
The object of this invention is to provide that a kind of crush efficiency significantly improves, simple to operate, long service life, do not cause the deep cooling type of secondary pollution to grind gaseous blast to environment.Its technical scheme is:
Comprise air compressor, air freezing drier, pulverizing chamber, vibrating feeder (conveyer), cyclone separator, material collecting barrel, bagroom, air-introduced machine, it is characterized in that: also comprise liquid nitrogen container, cooling water tank, water circulating pump, high temperature resistance furnace, temperature sensor, wherein pulverizing chamber housing adopts hollow structure, by outer wall, inwall and the middle cavity composition be evenly communicated with, outer wall there are cooling water inlet and coolant outlet, 1 is provided with to relative high speed nozzle in pulverizing chamber housing, high speed nozzle is connected with low temperature air inlet pipeline and high temperature air-inlet pipe road respectively, low temperature air inlet pipeline and high temperature air-inlet pipe road are respectively equipped with pressure regulator valve, Pressure gauge, and temperature sensor, low temperature air inlet pipeline is connected with liquid nitrogen container, high temperature air-inlet pipe road is by inner tube, heat-insulation layer, outer tube forms, high temperature air-inlet pipe road is connected with high temperature resistance furnace, the discharging opening of pulverizing chamber is connected with the charging aperture of cyclone separator.
Described deep cooling type grinds gaseous blast, and heat-insulation layer adopts ceramic fibre or asbestos fibre.
its operation principle is:air compressor produces gases at high pressure, gases at high pressure are dewatered by air freezing drier, oil removing, dedusting, cooling, purification source of the gas, then gases at high pressure enter pulverizing chamber respectively by high temperature air-inlet pipe road and low temperature air inlet pipeline, and gases at high pressure are heated to about 500 DEG C by high temperature air-inlet pipe road by high temperature resistance furnace and form high-temperature gas, gases at high pressure are made temperature form ultralow temperature gas at-80 DEG C ~-60 DEG C by low temperature air inlet pipeline by liquid nitrogen container cooling, material is fed in raw material by high temperature tracheae, high-temperature gas and cryogenic gas are accelerated into ultrasonic air-flow by superonic flow nozzzle, inject inlet zone, fluidization of material, material particles is accelerated under the effect of the huge kinetic energy of high velocity air, a pair nozzle is utilized relatively to spray, material is made mutually to carry out impacting and colliding from both direction each other, material particles is heated by high temperature gas flow simultaneously, when running into ultralow temperature airflow collision, there is deep cooling, granule interior stress is concentrated and produces micro-crack, even burst, and be easy to pulverize.Particle after pulverizing is collected by cyclone separator, guides air-flow to enter bagroom, carry out dedusting by bagroom to Exhaust Gas by air-introduced machine.
compared with prior art, tool has the following advantages in the present invention.
1, high-temperature gas about 500 DEG C, ultralow temperature gas is at-80 DEG C ~-60 DEG C, and particle is sharply lowered the temperature by higher temperature, and internal stress is concentrated, and make pulverizing easier, crushing efficiency is high, and the grain diameter after fragmentation is little.
2, hot high pressure air-flow can reach 500
dEG C, can improve air-flow spouting velocity further, material high-speed directly clashes, and impact strength is large, and capacity usage ratio is high.
