Description
Technical field
The present invention relates to a kind of automatic raw coal sampling device and coal storage system.
Background technology
During station boiler thermal test, raw coal sampling is an important step, after taking coal accurately to sample and could be
Continuous property indices, which calculate, provides real coal data.When carrying out boiler performance test, national standard GB10184-2015
Requirement to sampled fuels is：" it should be sampled from the solid matter streams of flowing, should be each if material inlet more than one
Material inlet constant duration is separately sampled." current raw coal sampling position mainly has upper coal belt and feeder to take two kinds of coal.Most
It is good to take coal position at feeder coal breakage bucket, as shown in figure 1, present takes coal measuring point very simple and crude, often directly in coal breakage
Opening at bucket, coal output pipe of burn-oning, then switch is used as using ring flange or ball valve.
In actual sampling process, present measuring point there are problems that it is following some：
One for the measuring point of flangeseal, ring flange need to be dismantled during coal by taking, but due to being malleation at this, once tear open
Fall ring flange raw coal and just spray to emit more than, be not only difficult to seal up again, and the raw coal that spray emits has a strong impact on periphery sanitary conditions.
Second, taking coal measuring point for what is closed with ball valve, because raw coal particle is larger, easily there is plugging problem, often go out
Now take situation about not producing coal.
Third, constant duration is sampled as manual control, it is difficult to through whole experiment process, or to take larger manpower
To run through whole experiment all the time.
