Specific embodiment
In order to make the technical problems, technical solutions and advantages to be solved by the utility model clearer, below in conjunction with attached drawing
And specific embodiment is described in detail.
The utility model is directed to existing pulverized coal preparation system raw coal bucket, especially sleet season, and raw coal moisture is bigger, frequently
Chute blockage, the defects of lower coal is unsmooth occurs, seriously affects the economy of the stability of boiler furnace burning, safety and pulverized coal preparation system
The problem of property.Up to 320 DEG C or so, mill exhauster outlet temperature highest needs pulverized coal preparation system hot blast temperature no more than 140 DEG C
Hot and cold wind rational proportion reaches running optimizatin, this results in 320 DEG C of hot wind temperature drop big, causes unnecessary energy loss.
In view of this, the utility model embodiment provides a kind of raw coal bucket coal-blocking-proof device of coal, and specific technical solution is as follows:
As shown in Figure 1, a kind of raw coal bucket coal-blocking-proof device of coal of the utility model embodiment, comprising: raw coal bucket 1, heating cabinet 2,
