As shown in Figure 6, coal dust anti-arc mixing device 8 comprises that one radially runs through the turning cylinder 81 of hopper 203 bottoms, turning cylinder 81 two ends outside hopper 203 respectively are provided with a T type oil sealing 82, the outside of T type oil sealing oil sealing 82 is by bolted connection one firmware 83, and firmware 83 is connected with turning cylinder 81 by bearing.One end of turning cylinder 81 axially connects a worm reduction gear 84 by flat key, and worm reduction gear 84 connects the mouth (not shown) of an electrical motor.Radially be connected with 85, three broken arch driving lever 85 coplines of three broken arch driving levers, one of a side, two of opposite sides on the turning cylinder 81 in hopper 203 after fastening by nut.
In the foregoing description, the quantity of broken arch driving lever 85 can be determined according to actual conditions, generally be not less than three, and also can adopt along the distribution mode of turning cylinder 81 spaced radial certain angles.
In the foregoing description, coal dust storage tank 1 and 2 outsides, weighing coal feed storehouse are all covered and are wrapped with the warm material (not shown), can make in coal dust storage tank 1 and the weighing coal feed storehouse 2 to keep certain temperature range, prevent that winter, outdoor temperature was crossed phenomenons such as low generation dewfall.
As Fig. 1, shown in Figure 7, pulse-free coal powder supply device 3 is arranged on the discharging opening below in weighing coal feed storehouse 2, and it comprises that a horizontally disposed conveying pipeline 301 and is horizontally set on the airduct 302 of conveying pipeline 301 belows.The closed at both ends of conveying pipeline 301, its upside near an end has an inlet point 303, and the downside of the close other end has a discharging opening 304.Inlet point 303 radially connects the discharging opening in weighing coal feed storehouse 2, and discharging opening 304 radially connects a material blanking tube 305.The first half of material blanking tube 305 is vertical, and the latter half tilts towards conveying pipeline 301 outsides.Be provided with a feed spiral 306 in the conveying pipeline 301, an end of feed spiral 306 close discharging openings 304 connects the mouth of an electrical motor 307, and electrical motor 307 is fixed on the outside of conveying pipeline 1.End near electrical motor 307 on the conveying pipeline 301 radially connects a stable-pressure device 308, and stable-pressure device 308 can make pressure and the external atmosphere pressure in the conveying pipeline 1 keep basically identical, thereby realizes stable material-supplying.
One end of airduct 302 radially connects material blanking tube 305, and the another port connects a blowing engine 309.The latter half of material blanking tube 305 is oblique to be connected in the airduct 302, makes to form an included angle A between the latter half of material blanking tube 305 and the airduct 302, and this included angle A is greater than the slope angle of repose of coal dust, and operated by rotary motion is between 30 °～60 °.Be provided with a Venturi tube structure 310 with material blanking tube 305 junctions in airduct 302, its effect is to make coal dust after passing through Venturi tube structure 310, and it is more even to produce coal.Also be provided with an Electric air valve 311 on the airduct 302, its effect is the wind supply quantity of regulating as required in the airduct 302.
Coal dust storage tank 1 of the present utility model is closed exhausting moisture valve 105 earlier in use, induced draft fan 107 is opened again, and will be delivered in the coal dust storage tank 1 by coal dust feeder sleeve 5 by the close coal dust that transports mutually of tank car then.During this period, in the coal dust storage tank 1 atmospheric pressure state, weary gas (weary gas is the air that coal dust deposition back discharges) is discharged by induced draft fan 107.Simultaneously, fluidization components device 6 pressurized air of jetting in hopper 103 problem that wall built-up, rat hole and conglomeration etc. hinder the coal blankings occurs to prevent the coal dusts in the hopper 103.The boiler automatic monitoring system is by level sensor 109, automatically the material level in the monitoring coal dust storage tank 1 just, when the coal dust in the coal dust storage tank 1 is in low material level (or high charge level), the boiler automatic monitoring system is reported to the police, and operating personal determines whether need to add powder (or stopping to add powder) with tank car in view of the above.Coal dust is imported in the process of coal dust storage tank 1 into, the boiler automatic monitoring system is monitored whether spontaneous combustion of coal dust in the coal dust storage tank 1 automatically by being installed in monitoring sensor (not shown) in the coal dust storage tank 1, when dieseling occurring, start liquid carbon dioxide fire extinguisher 108 and put out a fire.After the deposition of the coal dust in the coal dust storage tank 1 was static, the moisture in the coal dust upper air was discharged by exhausting moisture valve 105.For alleviating the harm that produces when coal dust is because of unexpected combustion explosion in the coal dust storage tank 1, when in a single day blast takes place, the pressed gas that blast produces can flick explosion door 106, plays the effect of release.
Operation along with steam generator system, coal dust anti-arc mixing device 8 starts simultaneously, coal dust in the steam generator system in the coal dust storage tank 1, mouth 206 falls automatically by being flexible coupling, enter in the weighing coal feed storehouse 2, with the weight data in weighing coal feed storehouse 2, conversion is sent to the automatic monitoring system in the steam generator system to LOAD CELLS 204, monitors in real time in real time.When the breeze material position in the weighing coal feed storehouse 2 is in lower bound, open rotovalve 7, start fluidization components device 6 simultaneously, coal dust storage tank 1 continues blanking; It is in limited time high that breeze material position in weighing coal feed storehouse 2 reaches, and then closes rotovalve 7, and coal dust storage tank 1 stops blanking.Air in the weighing coal feed storehouse 2 in the coal dust is discharged by exhaust cap 205, to keep in the weighing coal feed storehouse 2 and extraneous equilibrium of pressure.When three broken arch driving levers 85 of coal dust anti-arc mixing device 8 rotate, can constantly destroy the powder arch that forms in the hopper 203 or avoid occurring the powder doming effect.
Coal dust in the weighing coal feed storehouse 2 is delivered into the conveying pipeline 301 of pulse-free coal powder supply device 3 by the discharging opening of hopper 203.Under the drive of electrical motor 307, feed spirals 306 rotations in the conveying pipeline 301 will be advanced coal dust in the conveying pipeline 301 by 2 inputs of weighing coal feed storehouse, constantly deliver to the end of conveying pipeline 301, and fall in the material blanking tube 305.At this moment, because blowing engine 309 is blown by airduct 302, the coal dust that therefore falls into material blanking tube 305 falls under deadweight on the one hand, the drainage that is subjected to blast simultaneously falls, and enter in the Venturi tube structure 310, in airduct 302, under the wind effect, be delivered in the burning installation of boiler then.
The utility model only describes with the foregoing description; the structure of each parts, the position is set and connects and all can change to some extent; on the basis of technical solutions of the utility model; all improvement and equivalents of individual component being carried out according to the utility model principle all should not got rid of outside protection domain of the present utility model.
