1 top of a side body of 6 periphery of draught fan impeller offers air inlet 18.
Above-described embodiment in use, is first opened the first motor, the second motor, then will be blocky from feed inlet 2
Graphite raw material is put into, and the screw thread on a pair of of 3 surface of breaker roll is promoted by material extruding in shattering process and along axis, therefore some are big
The friction of roller more than 3 times that can be broken of block raw material crushes, and along with elastic rubber layer is included in breaker roll 3, encounters in graphite raw material and presss from both sides
Miscellaneous stone granules can also carry out flexible deformation, be not only avoided that force to crush the damage to breaker roll 3 in this way, but also can improve broken
Efficiency.And be pressed into powdered graphite and passed through from 4 mesh of sieve, the small blocky graphite of only a few is left on sieve 4, and
Coarse fodder outlet 5 is skidded off with the inclined direction along sieve 4, had not only needed to manually be screened, but also complete graphite powder and be classified
Journey.Again because cross-flow fan impeller 6 is internal in rotation process to form vortex air-flow, graphite powder is entering cross flow fan
By vortex airflow influence after in impeller 6, side swipe repeatedly between marume plate 11, has not only destroyed graphite powder in granulating cylinder 10
The protrusion part of particle surface, gradually forms spherical shape, while grain size further reduces, and is finally formed again by cross-flow fan impeller 6
Air-flow take discharge barrel 17 out of, not only spheroidization effect is good in this way, but also it is convenient to discharge, without manual cleaning.Meanwhile follow block 12
Moved up and down with the rotation of cross-flow fan impeller 6, but when bent axle 7 drive it is described lead be displaced downwardly to minimum point when, the sealing plate
15 lowest edge is contacted with 13 side wall of guide plate to close guide channel, and such follow block 12, guide plate 13, sealing plate 15 are with regard to shape
Into a sealing surface, during follow block 12 moves down, space increases between sealing surface and sieve 4, and air-flow will pour in drive
The graphite powder of 4 mesh of accumulated plugging sieve is deposited on follow block 12, then is slided into guide channel along 12 inclined direction of follow block, when
Bent axle 7 drives when moving to peak on the guide plate 13, and the lowest edge of the sealing plate 15 is separated with 13 side wall of guide plate
To open guide channel, during follow block 12 moves up, space reduces between sealing surface and sieve 4, and air-flow will be blown upwards
Block the graphite powder of sieve 4, at the same guide channel open after the inclined direction of graphite powder along sealing plate 15 slide into and draw flitch 16
On, then slide into cross-flow fan impeller 6 from flitch 16 is drawn, by setting 4 anti-blocking component of sieve, using being connected to cross flow fan
The rotation of bent axle 7 on impeller 6 drives follow block 12 to move up and down, and then the variation for generating the air pressure nearby of sieve 4 is formed across sieve 4
The air-flow of mesh, it is simple in structure and eliminate manual cleaning sieve 4 to dredge 4 mesh of sieve because of graphite powder accumulated plugging
Process.
In another embodiment, hairbrush is provided on the housing 1 side wall opposite with 3 periphery of breaker roll, institute
It states hairbrush to contact with 3 surface of breaker roll, in this way during breaker roll 3 works, hairbrush can just clear up breaker roll 3 automatically
The graphite that surface is stained with not only had avoided the loss of graphite raw material, but also has extended the time interval of manual cleaning breaker roll 3, avoided shutting down
Economic loss caused by maintenance.
In another embodiment, the thread pitch on the breaker roll 3 is 1st/20th of 3 length of breaker roll,
Such pitch is not thin close, and according to the hardness feature of pulverized graphite raw material, what can just be crushed is relatively complete, if pitch is more than
The length is then crushed by the roll-in of breaker roll 3 completely, larger to the pressure of 3 shaft of breaker roll 3 and breaker roll, easy damaged machine
Tool, hardness is not in the gap that very high graphite is easily filled between two adjacent rings screw thread, no if pitch is less than the length
Easily cleaning.
In another embodiment, 1 inner wall of the housing coating polytetrafluoroethylene material, such graphite powder are not easy to adhere to
1 inner wall of housing reduces the loss for causing raw material.
In another embodiment, the thread segment profile on the breaker roll 3 is isosceles trapezoid, accordingly even when there is graphite
Particle, which is stuck between two adjacent rings screw thread, to be also easier to clear up.
In another embodiment, for the mesh number of the sieve 4 more than 200 mesh, the graphite powder selected in this way passes through through-flow wind
Nodularization effect is best after machine impeller 6 is processed.
Although the embodiments of the present invention have been disclosed as above, but its be not restricted in specification and embodiment it is listed
With it can be fully applied to various fields suitable for the present invention, for those skilled in the art, can be easily
Realize other modification, therefore without departing from the general concept defined in the claims and the equivalent scope, it is of the invention and unlimited
