Embodiment
Below in conjunction with the accompanying drawings and specific embodiment the present invention is further illustrated.
Fig. 1 is that double-layer flap valve blanking system Double layer turning plate closes schematic diagram, including emission of baiting chute (1), Double layer turning plate (2),
The stomata (5) of circumference uniform distribution in the middle part of cylinder (3), lever (4), and elephant trunk；Double layer turning plate (2) rotary shaft is respectively fixed with
Rod member (6), rod member (7) is finally hinged with rod member (4), and cylinder (3) control Double layer turning plate (2) is closed.
Fig. 2 is that double-layer flap valve blanking system Double layer turning plate opens schematic diagram, including emission of baiting chute (1), Double layer turning plate (2),
The stomata (5) of circumference uniform distribution in the middle part of cylinder (3), lever (4), and elephant trunk；Double layer turning plate (2) rotary shaft is respectively fixed with
Rod member (6), rod member (7) is finally hinged with rod member (4), and cylinder (3) control Double layer turning plate (2) is in open mode.
Embodiment：As shown in Figure 1, 2, double-layer flap valve blanking system feed intake process Double layer turning plate (2) close, open two kinds
State, stop valve (9）、(10）, (11) control gas flow into.With reference to process for making process blowing blanking, blowing not blanking,
Do not blow Three models, by PLC control stop valve (9), (10), (11) switch, Double layer turning plate (2) overturn, realize with
The sealing means that Three models are consistent.With reference to Fig. 3 double-layer flap valve blanking system PLC control flow charts, illustrate Three models
The course of work.
In the blowing blanking stage, system sends blanking signal, and PLC control stop valves (9) are opened, stop valve (10) is closed, cut-out
Valve (11) is closed, and Double layer turning plate (2) is opened, ability blanking after postponing several seconds, and purpose ensures to fall on before Double layer turning plate under raw material,
Double-layer flap valve has already turned on, and reduces damage of the raw material to Double layer turning plate.Converting process produces high-temperature flue gas, emission of baiting chute aggregation
Substantial amounts of high-temperature flue gas, even flare, to prevent from lighting the raw material even equipment of scaling loss feed bin along the flare that elephant trunk is up altered,
Particularly in high-temperature flue gas safety in production is had a strong impact on containing a large amount of poisonous coal gas.Therefore, what stop valve (9) was passed through is high
Pressure, the nitrogen of big flow, and with rising opposite direction to flue gas, being intersected at a point with emission of baiting chute (1) axis on compacting flue gas
Rise, it is ensured that high-temperature flue gas will not be escaped, it is ensured that blanking process is safely and smoothly carried out.
Terminate in blanking, but still in the blowing stage, PLC control stop valves (9) are closed, stop valve (10) is opened, stop valve (11)
Close, Double layer turning plate (2) is closed.Although the stage emission of baiting chute still assembles substantial amounts of high-temperature flue gas, even flare, now
Double layer turning plate (2) is closed, and only a small amount of high-temperature flue gas is up escaped from turnover panel gap.What stop valve (10) was passed through be high pressure,
The nitrogen of low discharge, and with rising opposite direction to flue gas, being intersected at a point with emission of baiting chute (1) axis and suppress the flue gas of effusion
Rise, it is ensured that high-temperature flue gas will not be escaped, it is ensured that converting process is safely and smoothly carried out.
After finishing blowing, PLC control stop valves (9) are closed, stop valve (10) is closed, and stop valve (11) is opened, Double layer turning plate
(2) close.The a small amount of flue gas of the stage emission of baiting chute still populated with, now Double layer turning plate (2) close, flue gas is from turnover panel
Gap is up escaped.What stop valve (11) was passed through is the compressed air of low discharge, and with rising opposite direction, with to flue gas
Material elephant trunk (1) axis, which intersects at a point, suppresses the flue gas rising of effusion, it is ensured that flue gas will not be escaped, it is ensured that non-converting process safety
Smoothly carry out.
The blowing blanking stage is passed through the nitrogen of big flow, but the blanking time is shorter, and the total consumption of nitrogen is not high；Blow the not blanking stage
The nitrogen of low discharge is passed through, nitrogen use level is small；The stage of blowing is not passed through the compressed air of low discharge, and compressed air consumption is small, and
Compressed air price is cheap compared with nitrogen.On the whole, total nitrogen use level is reduced, and part nitrogen is replaced with compressed air, total
Cost is reduced.Meanwhile, converting process reduces nitrogen amount, reduces nitrogen and is reclaimed with high-temperature flue gas by gas recovering device, is improved
Gas concentration, improves coal-gas recovering amount.
