Common causes and solutions of coal blocking in coal weighing machine

With the development of coal and mining industry, the weighing coal feeder is widely used. In the daily construction process, the weighing coal feeder often encounters the situation of coal blocking, which can be divided into three situations: import coal bucket coal blocking, shell coal blocking and export coal blocking. How to deal with coal blocking of weighing coal feeder?

Weighing coal feeder shell and outlet coal blocking serious will cause the coal machine shell body full of coal powder, so that the coal feeder belt is easy to deviate, bearing damage, can not operate normally, and even shut down, thus affecting the normal coal supply, increase the labor of the operator.

After the reason is clear, the coal blocking of the weighing coal feeder shall be solved according to the following methods:

1. First, adjust the coal flow to ensure that the belt does not stray and the belt cleaning function;

2. Some weighing coal feeder outlet design is not reasonable, there is a dead Angle, leading to the shell outlet coal blocking. The outlet size of the weighing coal feeder produced by Xuzhou Sanhuai Heavy Industry is designed reasonably to avoid the appearance of dead angles and eliminate the phenomenon of coal blocking at the outlet of the shell;

3. The innovative research and development of the weighing coal feeder produced by our company, compared with the traditional machinery on the market, adjusts the Angle of the boiler inlet coal drop pipe and the weighing coal feeder outlet coal drop pipe to prevent the unblocked coal flow;

4. The coal mouth of the weighing coal feeder is more smooth, and the air pressure and air volume of the sealing air of the body and the coal sowing air are adjusted well.

5. You can choose to install the anti-blocking coal alarm device of weighing coal feeder. When there is coal blocking, the coal blocking alarm signal will be sent in time for timely treatment.
