Description

A kind of entirety based on many drain separators is weighed storage bin
Technical field
The present invention relates to field of thermal power, weighed storing in particular to a kind of entirety based on many drain separators Storehouse.
Background technology
The run coal bin that current power plant uses is important dress storage link in the pulverized coal preparation system of thermal power plant, its operation it is continuous Property direct relation burner hearth combustion conditions, influence unit safe operation.In current thermal power plant, in order to increase the stream of material Dynamic property, run coal bin lower section is generally back taper shape or hyperbolic conical.In addition limited by the entrance of belt feeder of weighing, raw coal Storehouse outlet size is smaller, and coal-fired to be wriggled downwards by deadweight, exit easily blocks, especially in the feelings that overcast and rainy and temperature is relatively low Under condition, chute blockage phenomenon will be more serious.Therefore for traditional run coal bin, chute blockage phenomenon is current domestic thermal power plant Generally existing, and with general character and problem demanding prompt solution.And for the measurement of the amount of delivering coal, what is used in the prior art is generally Belt feeder of weighing is measured.Due to weigh belt feeder need measurement flowing conveying coal amount, belong to dynamic measurement, its precision compared with Low, general precision is 0.5%, and measurement error is big, it is impossible to accomplish that accurate quantification is delivered coal.
Center feeder is the equipment of run coal bin material dosing output, and discharging is generally to be unloaded by the gravity type of material itself Material, which is easily caused the generation of chute blockage phenomenon.Be typically employed in the prior art run coal bin outer surface install vibrator or The devices such as air bubble, when there is chute blockage, mobility of the material in run coal bin are improved by vibrator or air bubble.But Using both approaches, not only efficiency is low, while can also there is cleaning dead angle, so that time effect more long will be more unobvious.Adopt With drain separator mode prevent blocking exist material fall after, be easily deposited in the lower section of drain separator, when run into it is larger or compared with During hard material, after the long period is run, easily there is the phenomenon for upwarping, anti-clogging after drain separator is upwarped in drain separator Effect will be substantially reduced, and colleague easily makes relevant device cause to damage, and causes production cost to increase.
