Abstract
The utility model relates to a material distributor for preheater of cement cylinder, which is arranged in each bowl body of a vertical cylinder preheater. The distributor is a truncated cone formed by that multilayer inclined plates formed to alpha angle with horizontal plane are formed to a circle and are sheathed together; the multilayer inclined plates are integrated into one unit by ribbed slabs, and the unit is vertically arranged in the bowl body by that a hanger plate passes through the necking of each bowl in suspension way. The utility model improves the condition of the gas-liquid heat exchange, increases the production of the kiln, and reduces the heat consumption. The utility model has the advantages of simple structure and easy installation.
Description
The utility model relates to the material diverting device in a kind of cement vertical cylinder preheater, is particularly useful for ZAB shaft preheater and KRUPP shaft preheater.
Quite a few cement rotary kiln tail is equipped with shaft preheater at present, but the advantage of shaft preheater is that strong, simple in structure, easy to operate, the unsuitable skinning of the adaptability of raw material is stopped up self-supporting; Its shortcoming is that the raw material powder can not fully disperse in air-flow, and Shi Youchong expects to take place, and interior back-mixing is serious, thermo-efficiency low (hear rate of unit mass product up to 5,016 thousand Jiao/more than the kilogram grog), the yielding poorly of kiln.According to incompletely statistics, China has more than 200 cement vertical cylinder pre-superheater kiln now, but does not almost have a Delta to design output.
The purpose of this utility model is to improve gas-solid two-phase heat exchange situation in the shaft preheater, overcomes to dash the material phenomenon, thereby improves the thermo-efficiency and the output of the pre-heating kiln of upright tube.
The purpose of this utility model is achieved in that in each alms bowl alms bowl body of shaft preheater and has lifted one by the multilayer tilted plate, the material decollator that a plurality of gussets and boatswain chair are formed.Multilayer tilted plate and horizontal plane have an angle α, and the spacing of each layer tilted plate had both guaranteed that material can not short circuit, can make air-flow unimpeded again.When the cement slurry powder ball strikes on the multilayer tilted plate of bulk cargo device with lumps from a last alms bowl preheater, broken into pieces and be evenly dispersed in immediately in the upstream, carry out effective heat exchange with high temperature gas flow then.
Below in conjunction with accompanying drawing material decollator of the present utility model is described:
Fig. 1 is that material decollator of the present utility model is installed in the intravital synoptic diagram of each alms bowl alms bowl.
Fig. 2 is vertical semisectional view of the utility model material decollator.
Fig. 3 is the vertical view of the material decollator of circle.
Fig. 4 is the vertical view of eight diagram-shaped material decollator.
Material decollator of the present utility model is the frustum that becomes the tilted plate that forms a circle 1 suit at α angle to form with horizontal plane by multilayer, be connected as a body with several gussets 2 between each layer tilted plate 1, with several boatswain chairs 3 the material decollator is lifted in each alms bowl body 4 of shaft preheater, vertically hangs down by each alms bowl reducing place.The inclination alpha of each tilted plate is 40-70 °, and the number of plies of tilted plate 1 can be the 4-20 layer, and the gusset quantity that tilted plate is connected to a frustum is 4-8, and the quantity of boatswain chair adopts 3-8 generally according to the volume size of the frustum that forms.Spacing between each tilted plate 1 will make the raw material powder ball directly pass through.
The multilayer tilted plate 1 of material decollator of the present utility model can adopt the annular plate, and connects cover with gusset 2 and dress up the frustum of a cone.
In addition, material decollator of the present utility model also can adopt by eight diagram-shaped tilted plate 1 suit of multilayer, and connects into anistree frustum with gusset 2.
The advantage of material dispersion device of the present utility model is: by means of this material dispersion device, material can be well-dispersed among the air-flow equably, and gas-solid heat exchange situation is improved, and makes the output increased of kiln, and hear rate descends; Owing to overcome " punching material " phenomenon, system run all right, convenient operation; The movement-less part of this material dispersion device own moves, installs, changes more convenient.
