Buried scraper conveyor in delivering coal Precautions
Currently our factory milling systems use buried scraper conveyor transporting coal to the ball mill, and its advantage is that it has a coal feed rate uniformity, continuity,
adjustability of the amount of coal and job stability. In the coal bucket fitted in the waist position of the oscillator, whose role is to loose coal hopper blockage coal,
pulverized coal gravity fall. But in actual operation use is often ineffective, but to make the pulverized coal hopper vibration the more the more real, not fall, thus giving
the work a great deal of trouble to run, not only increases the workload, but also make the system Powder power consumption increases, the reason is analyzed as follows:industrial belt conveyor
First, we coal be regarded as a substance having fluidity, under normal circumstances, they can be mobile, but relatively moist coal, water increases, too small, or coal, its
viscosity and friction is increased, reduced liquidity, then when a large number of coal, while coal bucket by the throat when it is easy to shed live off the formation of new
coal. In addition, the coal in the straw, wood and other bulky debris child can easily cause a blockage in the coal bucket, affecting the flow of coal, resulting in broken coal.
After breaking coal, coal bucket attendant took advantage of its lower oscillator procure coal, the oscillation, a large coal falls, so when the whereabouts of the pulverized material handling conveyor
coal feeder is greater than the amount of pulverized coal scraper away, in a limited The passage to the coal, coal bucket of coal flow can not be formed, and the formation of
blockage was again broken coal, which makes handling a broken coal recovery takes a long time, or even require more manpower.
According to the case, and can have a way to promote the flow of pulverized coal. Maintain a continuous flow of pulverized coal, so coal bucket will not form a plug, we noted
previously processed when the stoker coal-off speed has not changed, that is, the amount of coal to the coal conveyor size has not changed, even someone will it decrease. This
is not conducive to the flow of coal, but hindered mobility.
In summary, in the future we deal with broken coal can be first coal feeder speed is increased, a large number of coal by shaking whereabouts, through the high speed of coal
feeder away, strengthened pulverized coal passive mobility, so as not to form a plug until after continuous flow (see current) recoverable coal feeder speed to normal.
