The stock guide of adjacent rows row is staggered and the spacing between the stock guide of adjacent ranks is 200-500mm.
Its further technical scheme is：
Projection of the stock guide on spreading plate and the central axial direction of the tremie pipe are arranged in 45 ° of ranks.
The structure that the stock guide of the adjacent ranks is staggered is：Apart from tremie pipe center in the stock guide of a certain ranks
The top of two pieces of nearest symmetrically arranged first stock guides of axis direction is closely packed together, other stock guides of the ranks along this two
The angle direction of the stock guide of block first is intervally arranged；Apart from tremie pipe central axial direction in ranks stock guide adjacent with the ranks
The top of two pieces of nearest symmetrically arranged second stock guides separates, and the top of two piece of second stock guide is along blanking tube hub
The drop point of axis direction overlaps with the tail end of the first stock guide in adjacent ranks stock guide, and other stock guides of ranks edge should
The angle direction of two piece of second stock guide is intervally arranged.
The stock guide rectangular plate structure.
The long 200-500mm of stock guide, wide 5-20mm, high 5-20mm.
Advantageous effects of the present utility model are：The material guide structure is according to certain angle and arrangement side on spreading plate
Formula is provided with some stock guides, using the specific angle of stock guide and distribution mode, can effectively overcome the adhesion between solid material
Power, the material of center concentrated area is set to improve the dispersiveness and uniformity into the material of dore furnace to edge distribution, so as to
Strengthen the mixed heat transfer effect of material and flue gas, further improve the hot property of dore furnace.

Embodiment
In order to better understand technological means of the present utility model, and can be practiced according to the content of specification,
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail, following examples are used
In explanation the utility model, but it is not limited to the scope of the utility model.
A kind of material guide structure in cement decomposing furnace blanking device described in the utility model, including bottom is with spreading
The tremie pipe 1 that hopper 2 connects and the spreading plate 3 being arranged in spreading case 2.Between the characteristics of material guide structure, is on spreading plate 3
Every being installed with some pieces of plate faces and the perpendicular stock guide 4 of spreading plate plate face, the stock guide 4 is prepared by high-abrasive material,
It is preferably rectangular flat plate shape structure in this specific embodiment, size is preferably long 200-500mm, wide 5-20mm, high 5-
50mm.Above-mentioned some stock guides are symmetrical arranged along the central axial direction of tremie pipe, and on the spreading plate of some pieces of stock guides 4
Projection and the central axial direction of the tremie pipe are arranged in 40-60 ° of ranks, and optimal angle is 45 °, is selected in this specific embodiment
With 45 °.In addition, the stock guide of adjacent ranks is staggered, specific setting is simultaneously as described below referring to accompanying drawing 2：A certain ranks
