The embodiment to the present invention is described further below in conjunction with the accompanying drawings：
See Fig. 1, be the structural representation of the present invention, a kind of discharge device for continuous dry furnace of the invention, including
Housing 1, rotating shaft 19, coke discharging roller 2, supporting arrangement 5,10 and drive device 7, the coke discharging roller 2 pass through rotating shaft 19 and driving
Device 7 is connected, and supporting arrangement 5,10 is separately fixed at the two ends of housing 1 and supports rotating shaft 19 and rotates；The outside of coke discharging roller 2 sets housing
1, the top of housing 1 is provided with the feeding mouth 12 adaptable with destructive distillation room bottom discharge mouthful size, and the bottom of housing 1 sets out material mouth 17；Enter
The side plate of material mouth 12 is provided with temperature-detecting device 3 and pressure test device 4, and the side plate of discharging opening 17 sprays mouth 9 provided with cooling water.
Gap 18 between housing 1 and coke discharging roller 2 outer wall is less than the particle mean size of handled material.
The side plate of feeding mouth 12 is respectively arranged on the both sides of feeding mouth 12 and the vertically hang plate of elongated setting for 2 pieces, its
Latus inframedium 1 is located at front end during coke discharging 2 return of roller, and side plate 2 13 is located at rear end during coke discharging 2 return of roller；Side plate one
The distance of 11 lower ends and vertical axis is less than the distance of the lower end of side plate 2 13 and vertical axis；Side plate 2 13 is provided with temperature detection
Device 3, pressure test device 4 and manhole 14.
The temperature-detecting device 3 is temperature sensor, and pressure test device 4 is baroceptor, temperature sensing device 3
Control system is connected respectively with air pressure sensing device 4.
At least one peripherally disposed elongated feed bin 16 of the coke discharging roller 2, when feed bin number is more than 1, adjacent material
The centerlines in storehouse 16 are more than the opening angle of feed bin 16.
Cooling water sprinkling mouth 9 is multiple, on the side plate that the both sides of discharging opening 17 are uniformly arranged on vertically, and respectively with
Cooling water pipeline is connected.
As Figure 1-Figure 2, discharge device of the present invention by housing 1, rotating shaft 19, coke discharging roller 2, supporting arrangement 1,
Supporting arrangement 2 10 and drive device 7 are constituted；Supporting arrangement 2 10 and supporting arrangement 1 connect with the left and right ends of housing 1 respectively
Connect, the two ends of rotating shaft 19 are supported by supporting arrangement 1 and supporting arrangement 2 10 respectively；Drive device 7 passes through shaft coupling 6 with rotating shaft 19
Connection, is coupled with housing 1 by connection seat 8；Discharge roller 2 is provided with feed bin 16.
As shown in figure 3, the feeding mouth 12 of the discharge device is located at the top of housing 1, connected by flange and destructive distillation room bottom
Connect, the hole size of its flange hole size and destructive distillation room bottom discharging opening is adapted, when drive device 7 passes through the band of shaft coupling 6
Dynamic coke discharging roller 2 is when direction is rotated as shown in Figure 3, and the clinker of destructive distillation room bottom falls to filling up coke discharging rolling automatically under gravity
The feed bin 16 of cylinder 2, to ensure the uniformity of destructive distillation room bottom material discharge along its length.It is located on the both sides side plate of feeding mouth 12
Temperature and pressure situation when can clinker be discharged of temperature-detecting device 3 and pressure test device 4 get forwarded to control system.
The gap 18 of coke discharging roller 2 and housing 1 is less than the particle mean size of handled material, and so most of material would not
Into this gap 18, the arc surface being spaced additionally, due to feed bin 16 is sealed together with being formd between housing 1, granular material and
Material less than material particle mean size is also difficult to by gap because of the effect of frictional force between material and arc surface and housing 1,
It ensure that the controllability of discharge.When temperature-detecting device 3 detects temperature of charge higher than setting value, cooling water sprinkling mouth 9 is just
Cooling water can be sprayed automatically, and the water cooling for making material be ejected during discharging opening 17 is fallen on from feed bin 16 plays supplement
The effect of cooling.
