Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Describe, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments wholely.Based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under not making creative work premise
Embodiment, broadly falls into the scope of protection of the invention.
Refer to the front view that Fig. 1, Fig. 1 are the impact type pulverization machines for producing polyurethane that the present invention provides.For
The impact type pulverization machine producing polyurethane includes: hopper 1, cryovial 2, primary comminution portion 3, airduct 4, shock smashing portion 5
And catcher 6.
Hopper 1 upper end open, lower end is provided with valve 11, and valve 11 can be configured to intermittent unlatching and close
Close.
Cryovial 2 includes nitrogen storage tank 21, jet pipe 22 and material blanking tube 23.Material blanking tube 23 is vertically arranged, and upper end connects valve
Door 11, side connects nitrogen storage tank 21 by jet pipe 22.Jet pipe 22 has many, equally spaced is vertically arranged.Nitrogen storage tank
21 can be arranged to intermittent open and close, and frequency is identical with valve 11.
Primary comminution portion 3 is provided with charging aperture (not shown) and discharging opening 31, the lower end of charging aperture connection material blanking tube 23, goes out
Material mouth 31 connects the upper surface of airduct 4.Primary comminution portion 3 can say that raw material is ground into 0.1 millimetre-sized microgranule.
Airduct 4 is horizontally disposed with, upper surface connection discharging opening 31, and airduct 4 one end is provided with an aerator 41, and the other end is even
Connecing shock smashing portion 5, shock smashing portion 5 and discharging opening 31 are positioned at the same side of aerator 41.
Refer to the shock smashing portion that Fig. 2, Fig. 2 are the impact type pulverization machines for producing polyurethane that the present invention provides
Top view.
Clashing into smashing portion 5 be disc, is inside provided with many and pulverizes pipes 51, pulverizes thick one end, pipe 51 one end carefully, internal diameter by
Tapered little.The butt end of all pulverizing pipes 51 is uniformly distributed and the surrounding clashing into smashing portion 5.The taper end of all pulverizing pipes is arranged at hits
Hit the circle centre position of smashing portion 5, and be connected with catcher 6.A diameter of 10 microns of taper end.
Hopper 1, cryovial 2, primary comminution portion 3, airduct 4 number are two, set about clashing into smashing portion 5 symmetry
Put.It is provided with two plate washers 52, it is to avoid the gas with raw materials particles of aerator 41 blowout of both sides in clashing into smashing portion 5
There is convection current in stream.
Catcher 6 connects the taper end of all pulverizing pipes 51, and catcher 5 is provided with multiple steam vent (not shown), aerofluxus
Dust arrester 61 it is provided with at hole.
During production first by raw material storing in hopper 1, start whole machine.The intermittent unlatching of valve 11 is closed
Closing, make a part of raw material drop into cryovial 2 every time, in raw material dropping process, nitrogen storage tank 21 is opened, liquid nitrogen warp
Cross jet pipe 22 to spray in material blanking tube 23, in raw material dropping process, it is cooled down rapidly so that it is fragility increases, it is simple to carry out
Pulverize.
Raw-material dropping in primary comminution portion 3 after being frozen is pulverized, and is ground into 0.1 millimetre-sized
Grain.Later falling in airduct 4, the wind blown out by aerator 41 is pulverized in being blown into shock smashing portion 5 further.When this
A collection of raw material is after primary comminution portion 3 pulverizes, and valve 11 is opened again, makes next group raw material drop into cryovial
In be processed.
Entered into shock smashing portion 5 by the raw material after primary comminution, under the drive of air-flow, enter into pulverizing pipe 51
In, the internal diameter pulverizing pipe 51 progressively reduces, and air velocity is gradually increased so that raw material powder has bigger kinetic energy.Pulverize
Pipe 51 is designed to many kinkings structure, and raw material powder clashes into during pulverizing pipe 51 and is knocked into less granule.If former material
Material powder is stuck in pulverizing pipe 51, and high velocity particle below also can be crashed, finally by the particle size pulverizing pipe 51
Less than 10 microns.
The raw material crushed enters in catcher 6, and unnecessary gas is discharged from steam vent, and dust arrester 61 ensure that
In exhaust process, raw material powder will not be taken out of together.
Implement the embodiment of the present invention, have the advantages that the impact type pulverization for producing polyurethane of the present invention
Raw material effectively can be ground into 10 micron-sized little granules by machine, effectively improves the production quality of polyurethane finished product.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all essences in the present invention
Within god and principle, any modification, equivalent substitution and improvement etc. made, should be included within the scope of the present invention.
