In figure: 1. long 11. conical outlet of feed tube, 2. dynamic plugging devices 21. block 22. bracket of disk, 23. vertical shaft 24. big 4. shaft furnace inner cavity of burden-guiding cone, 5. charge level of 25. linear actuator of pivoted arm 3.
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 Dynamic device drives the non-block-up position (position I in Fig. 2) for being in big burden-guiding cone outside suitable for reading, and at this moment material is through on big burden-guiding cone Mouth falls directly on the center of shaft furnace circular cross-section.When needing material being arranged in 5 edge of charge level, dynamic plugging device 2 In block disk 21 by pendulous device drive be in big burden-guiding cone surface suitable for reading block-up position (the position II in Fig. 2), greatly Granule materials are scattered from 21 edge of disk is blocked, and glide through big 3 conical section of burden-guiding cone, fall in shaft furnace circular cross-section side along its edge Edge position.
Port radius on big burden-guiding cone, the bevel edge floor projection of big burden-guiding cone 3, big burden-guiding cone 3 edge to shaft furnace kiln wall Than being about 1:2:1, this can guarantee to form waveform charge level distance.When closure disk 21 turns to non-block-up position, dynamic plugging There cannot be any part to stop big burden-guiding cone suitable for reading in device 2, in order to avoid influence cloth.
11 diameter of conical outlet of long feed tube 1 will be much smaller than the diameter of long feed tube 1, make long 1 lower part Ke Dui of feed tube The certain lime stone of product, plays the purpose of guide, makes stream direction vertically downward.
The bottom surface for blocking disk 21 is greater than 150mm apart from big burden-guiding cone distance suitable for reading, and two equipment when material impact is avoided to bump against.
Big burden-guiding cone lower port diameter is the 3/4 of kiln thorax internal diameter, it is ensured that certain granule materials is deployed to kiln thorax edge.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto, Anyone skilled in the art in the technical scope disclosed by the present invention, according to the technique and scheme of the present invention and its Inventive concept is subject to equivalent substitution or change, should be covered by the protection scope of the present invention.
