Description

Birotor beater disintegrating machine
Technical field
The utility model relates to a kind of mechanical device that material is pulverized, and specifically, the utility model relates to a kind of birotor beater disintegrating machine.
Background technology
In prior art, for the beater disintegrating machine of comminuting matter, it mainly includes housing, and housing top offers charging aperture, is provided with rotor in housing, and rotor periphery is surrounded and is provided with sieve, forms pulverizing chamber, and sieve top is connected with the transition of charging aperture downside.
When existing this device work, material enters in pulverizing chamber from the charging aperture on sieve top, and rotor high-speed rotates, and material is repeatedly hit pulverizing by hammer leaf.Material is made high speed circular motion in pulverizing chamber, forms a material fluid layer along compass screen surface rotation, and this material fluid layer is called circulation layer.Under the effect of centrifugal force, the bulky grain in material can accumulate in circulation layer periphery, and short grained material accumulates in circulation layer inner side.Oarse-grained material stops that short grained material, through sieve, makes pulverizer Efficiency Decreasing; Meanwhile, because short grained material can not pass sieve aperture, cause its in pulverizing chamber by hammer leaf multiple impact, temperature raises, and brings the potential safety hazard of fire.In addition, high grease, multifilament, glutinous viscosity, water content comminuting matter high or dampness can cause stifled sieve and stick with paste sieve phenomenon, and then cause the low problem of pulverizer crush efficiency.
The patent No. is that the Chinese invention patent description of ZL200610025617.4 discloses a kind of pulverizer and breaking method thereof, this pulverizer has two charging apertures and two pulverizing chamber, in two pulverizing chamber, respectively there is rotor with hammer leaf at High Rotation Speed, and between two rotors, be provided with the guiding device that material is played to guiding and shunting action.When entering the second pulverizing chamber through pulverizing the not qualified material that goes out to sieve under guiding device effect in the first pulverizing chamber, clashed into by the hammer leaf in the second pulverizing chamber and pulverize, in the second pulverizing chamber, under guiding device effect, enter the first pulverizing chamber through pulverizing the qualified material that goes out to sieve in end simultaneously, clashed into and pulverize by the hammer leaf in the first pulverizing chamber.Not qualified go out the Matter Transfer of sieve pulverize until after qualified, then the screen cloth arranging by pulverizing chamber bottom goes out sieve.
In foregoing invention patent, between the rotor of two of disclosed pulverizer pulverizing chamber, be provided with guiding device, but this guiding device is mainly that material is played to guiding and shunting action, material is mutually clashed into hammer leaf in the situation that having component motion, and the direction of motion relatively or substantially relative.But this structure decrease the mutual shock between material flow, easily make material in pulverizing chamber separately, form logistics ring along with rotor rotates, may reduce so on the contrary the probability that material is clashed into by hammer leaf, cause material cannot be crushed at short notice the granularity of setting, increase grinding time, reduced crush efficiency.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of birotor beater disintegrating machine, can thoroughly break crushing material time in pulverizing chamber along with rotor rotates the logistics ring forming, material is pulverized rapidly within the shortest time.
For solving the problems of the technologies described above, the utility model provides a kind of birotor beater disintegrating machine, comprises base and frame housing is thereon set, and described frame housing top offers one or two charging aperture; In described frame housing, be provided with two sieves, each described sieve presents a major arc shape, and the opening of described sieve is connected with described charging aperture; In each described sieve, be provided with a rotor, on the excircle of each described rotor, be provided with multiple hammer leaves, described rotor and described sieve form two relatively independent pulverizing chamber altogether, and described rotor rotates around main shaft separately in its described pulverizing chamber separately together with the described hammer leaf on it; Between two described rotors, be provided with and clash into rod, two spaces between described rotor are separated hermetically by non-.
Alternatively, the quantity that described shock is excellent is two or three, is horizontal placement, along vertical array.
Alternatively, described clash into spacing each other of rod with and and described rotor between spacing be all adjustable.
Alternatively, the cross section that described shock is excellent is positive circular, oval, regular polygon or irregularly shaped.
Alternatively, the cross section that multiple described shocks are excellent is identical or different thickness and/or shapes each other.
Alternatively, the major arc that described sieve presents is just round major arc or oval major arc.
Compared with prior art, the utlity model has following advantage:
Birotor beater disintegrating machine of the present utility model, have two pulverizing chamber that are connected, by the shock rod of some is set between two rotors, two spaces between rotor are separated hermetically by non-, form multiple area of space that are communicated with, thereby make:
1) in the time that pulverizer is worked, crushed material is impacted to strike by hammer leaf and clashes into rod above, and then in bounce-back and pulverizing chamber, other crushed material clashes into, and formation is the sinuous flow of shock mutually, and mobile crushed material is upset;
2) in the time that pulverizer is worked, in two pulverizing chamber, mutually clash into bounce-back with the mobile comminuting matter of rotor by the space of clashing into rod and clash between rod, mobile material is upset;
3), in the time that pulverizer is worked, the crushed material in two pulverizing chamber clashes into mutually by the space of clashing between rod and pulverizer, upsets the comminuting matter of circulation.
By above 3 points, comminuting matter has experienced multiple mutual shock and has clashed into bounce-back, so between rotor and rotor, be knocked in this panel region that rod separates, crushed material has formed mixed and disorderly unordered phenomenon, rotates thereby thoroughly broken pulverizer material in the time of work the logistics ring forming with rotor.The utility model makes material under the strike of hammer leaf, be pulverized out rapidly pulverizing chamber within the shortest time, has reduced grinding time, has avoided the inefficient operation of pulverizer, has from then on significantly improved crush efficiency, has saved energy consumption, has increased output.
