The specific embodiment
The utility model will be further described below in conjunction with drawings and Examples.
Fig. 1 is the utility model belt weighing formula feeder corollary apparatus structural representation.
See also Fig. 1, the belt weighing formula feeder corollary apparatus that the utility model provides refers in particular to the coal spout 2 and the belt conveyor 6 of run coal bin 1 and belt weighing formula feeder, described coal spout 2 intersects at feeder 5 entrance with belt conveyor 6, wherein, in the described coal spout 2 a bevelled dividing plate 3 is set.
At big-and-middle-sized thermal powerplant of modern times, the coal of burning usefulness is sent by run coal bin 1, along with coal spout 2 at the bottom of the storehouse, naturally fall in the belt weighing formula feeder 5 that is attached thereto, raw coal is routed to belt conveyor 6 after belt weighing formula feeder entrance is by shaping (making the limit for height limit for width handles) then, be transferred to feeder 5 outlets by the belt conveyor 6 that rotates, carry out the processing of later process again.
Fig. 2 is the utility model belt weighing formula feeder corollary apparatus coal spout sectional area size variation figure.
Please continue referring to Fig. 2, for preventing coal spout 2 meticulous blockage phenomenon, the designer gets coal spout 2 internal diameters greatly mostly as far as possible.If area (vertical projection the area)-abbreviation A area that will form by coal spout 2, and the flow area that feeder inlet is allowed to be carried by belt (drift diameter area that forms by feeder inlet shaping baffle plate and belt)-abbreviation B area, there is very large difference in these two areas as seen from the figure, usually B is much larger than A, according to the latus rectum of the logical direction fwd latus rectum of circulation principle longshore current smaller or equal to the back, it is without hindrance then to circulate, and it is effective to circulate.Present situation is then just in time opposite, the fwd latus rectum is far longer than the latus rectum of back, certainly will cause the raw coal of most B-A to be blocked and to be transferred away like this, can only remain in the original place, the raw coal of these delays is in the belt rotation process, under the effect of pressing in the storehouse with belt generation rubbing effect, result after the long-term use is that belt is not that to be scratched be exactly by wear down, the numerical value of B-A is big more, the resistance that belt is subjected to is also big more, consume does not say that for the energy that overcomes unnecessary resistance and need the probability that belt conveyor damages is just high more, weares and teares soon more in vain.
