Specific embodiment
Specific embodiments of the present invention will be further explained with reference to the accompanying drawing:
As shown in Figure 1 and Figure 2, one kind of the present invention can calcine the shaft furnace combined type distribution device of small grain size lime stone,
Including long feed tube 1, dynamic plugging device 2 and the big burden-guiding cone 3 being successively set at shaft furnace top feed mouth from top to bottom；Institute
The lower part for stating long feed tube 1 is equipped with the conical outlet 11 of retracted downward；Big burden-guiding cone 3 is up-small and down-big hollow cone；Dynamically
Plugging device 2 is made of closure disk 21 and pendulous device, block disk 21 can pendulous device drive under horizontal hunting, block disk
1 endpoint of 21 swing paths is located at the surface of big burden-guiding cone 3 and can block big burden-guiding cone is suitable for reading completely, another
Endpoint is located at big burden-guiding cone outside suitable for reading.
11 diameter of conical outlet of the long feed tube 1,21 diameter of closure disk of dynamic plugging device 2, on big burden-guiding cone
Mouth diameter is equal.
Port radius on the big burden-guiding cone, the bevel edge floor projection length of big burden-guiding cone 3, big burden-guiding cone 3 edge to perpendicular
The ratio of distances constant of kiln kiln wall is 1:2:1.
The 2/3 of 1 upper entrance diameter of the conical outlet diameter of the long feed tube 1≤long feed tube.
At a distance from 21 bottom surface of closure disk on the dynamic plugging device 2 and big burden-guiding cone are suitable for reading >=150mm.
Big burden-guiding cone lower port diameter is the 3/4 of kiln thorax internal diameter.
The dynamic plugging device 2 is made of closure disk 21, bracket 22, vertical shaft 23, pivoted arm 24 and linear actuator 25, line
Property actuator 25 be fixed on outside shaft furnace, the power output end of linear actuator 25 drives support by 24 connecting bracket 22 of pivoted arm
Frame 22 horizontally rotates around vertical shaft 23, and it is fixed on the tray 22 to block disk 21.
One kind of the present invention can calcine the shaft furnace combined type distribution device of small grain size lime stone use process is as follows:
Raw material limestone enters shaft furnace inner cavity 4 through too long feed tube 1, and long feed tube 1 has enough length to guarantee lime stone stream side
To being straight down.11 diameter of conical outlet, the dynamic plugging device 2 of long feed tube 1 block 21 diameter of disk and big burden-guiding cone
Back cut diameter is equal, for adjusting the trend of different grain size lime stone.
As shown in Fig. 2, the closure disk 21 in dynamic plugging device 2 is by putting when needing material being arranged in 5 center of charge level
