From coal pulverizer material particles out under the drive of air-flow, by after one section of pipeline more long, dynamic being ground from coal
The feeding mouth of powder concentrator bottom enters in coal mill Dynamic Separation machine, and the less material particles for meeting use requirement of granularity are in gas
Under the drive of stream, outflow is exported from the fines of powder concentrator；The larger material for not meeting use requirement still of granularity is by with blade
Rotor banding turn, be thrown under the influence of centrifugal force coal mill Dynamic Separation machine inwall on, then under gravity via
Tapping channel is exported from coarse fodder and flowed out；Drying hammer mill is still transported to again by sieving remaining large granular materials
In crusher chamber, the broken of next round is carried out.
The problem that existing processing mode is deposited is：Remaining thick material is carried out after needing to being sieved through dynamic coal milling powder-selecting machine
Collect, transport, thick material is sent back in the crusher chamber of disintegrating machine again, waste the working time, operating efficiency is relatively low.

The beneficial effects of the utility model are：The discharging opening of dynamic coal milling powder-selecting machine is broken with drying hammer crushing seperator
Broken chamber is connected, and the larger material particles of remaining volume are under gravity along selecting powder after dynamic coal milling powder-selecting machine screening
The tapping channel of machine is come back in crusher chamber, reduces the intermediate transportation time of material, improves operating efficiency.
Brief description of the drawings
Fig. 1 is the structural representation of the embodiment 1 of drying hammer crushing seperator of the present utility model.
Specific embodiment
Implementation method of the present utility model is described further below in conjunction with the accompanying drawings.
The embodiment 1 of drying hammer crushing seperator of the present utility model, as shown in figure 1, including casing 1,1 in casing in
Be provided with the broken rotor of hammer, the left side at the top of casing 1 is feeding mouth, be provided with impeller discharge valve 2 at feeding mouth, the right side of feeding mouth be into
Air port；The right side at the top of casing 1 is the first discharging opening, and the first discharge outlet is provided with dynamic coal milling powder-selecting machine 4.
Vane rotor is provided with dynamic coal milling powder-selecting machine 4, vane rotor is by drivers such as frequency control motor and reductors
Structure drives, and is provided with the grid cylinder of tubular structure in dynamic coal milling powder-selecting machine 4 on the outside of vane rotor, is provided with below vane rotor
Cone 6, the lower section of cone 6 is connected to discharge nozzle 7, and cone 6 and discharge nozzle 7 form tapping channel.
Operationally, from air inlet 3 to hot blast is passed through in casing 1, on the one hand hot blast takes away the water of material to embodiment 1
Point, material is dried；On the other hand, motion of the flowing of hot blast to material particles in casing provides power；Coal cinder from
Impeller discharge valve 2 enters casing 1, and is collided with the broken rotor of hammer.In the presence of the broken rotor of hammer, coal cinder is dispersed as particle
The material particles of shape, material particles enter dynamic coal milling powder-selecting machine 4 under the drive of hot blast via the discharging opening of the left end of casing 1
It is interior.
After material particles enter dynamic coal milling powder-selecting machine 4, material particles are first in the outside of grid cylinder, by grid 9 pairs of things of cylinder
Material particle carries out the screening of first time, and the larger material of volume is isolated in grid cylinder outside, and the material of small volume enters grid cylinder
9.The quality of the smaller small material particles of volume in grid cylinder 9 is smaller, and influence of the air-flow to small material particles running orbit is larger,
Small material particles directly flow out with air-flow via tapping channel 5；In order to prevent blast, explosion-protection equipment is set on tapping channel 5
8；The quality of the larger big material particles of volume in grid cylinder 9 is larger, influence of the air-flow to the running orbit of big material particles compared with
Small, big material particles collide with vane rotor, and vane rotor drives big material particles to rotate, and big material particles are in centrifugal force
In the presence of be thrown on the inwall of dynamic coal milling powder-selecting machine 4, then under gravity, via dynamic coal milling powder-selecting machine 4
The material channel of bottom is come back in the crusher chamber of casing 1, and carry out next time is broken.
It should be noted that：The size of the material particles obtained after being screened through dynamic coal milling powder-selecting machine 4, on the one hand grinds with coal
The rotating speed of the vane rotor in dynamic powder concentrator 4 is relevant, i.e. the material particles that the bigger screening of rotating speed of vane rotor is obtained are thicker；
On the other hand, the size of material particles can also be influenceed by factors such as crusher chamber temperature, humidity, the blast in casing 1, therefore
The present apparatus carries out preliminary operation, it is necessary to pass through to change above-mentioned influence factor in use, until discharging-material size meets actual requirement.
In the other embodiment of embodiment 1, casing 1 can also be provided separately with dynamic coal milling powder-selecting machine 4, will use pipe
With the crusher chamber of casing 1 be connected the tapping channel of dynamic coal milling powder-selecting machine 4 by road.
