Described stopple coupon is plugged in airduct road, is used for gathering the ducted air-flow of wind;
Described wind speed compared with control device is used for air-flow velocity in airduct road air-flow velocity of contrast and the stopple coupon, and sends steering order to described air pump;
Described coal dust disconnecting gear is used for coal dust and burbling, collects coal dust simultaneously;
Described air pump is discharged described sampler with air-flow, for the uniflux of air-flow in sampler provides power, regulates self rotating speed by receiving described steering order, makes in the described stopple coupon in air-flow velocity and the airduct road air-flow velocity same.
Further, described stopple coupon is provided with once distinguished and admirable thief hole of going into of one or more confessions.
Further, described coal dust disconnecting gear comprises one-level coal dust disconnecting gear and secondary coal dust disconnecting gear.
Further, described steering order comprises the raising rotating speed, reduces rotating speed.
Further, the connecting line between described wind speed compared with control device and the described coal dust disconnecting gear is flexible pipe, and coal dust disconnecting gear and described air pump are installed on the frame, and described frame is the movable machine frame that the bottom has roller.
The touch formula liquid crystal control operation screen of the described sampler opening and closing of control further, also is installed on the described frame.
Further, be equipped with on the described stopple coupon for the temperature sensor of measuring temperature in airduct road.
Further, separation valve door is installed also before the described coal dust disconnecting gear, close described separation valve door after described stopple coupon can gather once pneumatic pressure and static pressure.
Further, be connected with filtrator between described coal dust disconnecting gear and the described air pump.
A wind isokinetic sample of pulverized coal of the utility model device has overcome can't make the air-flow velocity deficiency consistent with air-flow velocity in the stopple coupon in airduct in traditional sampling equipment; By coal dust disconnecting gear and air pump are arranged on the frame that has roller, it is on-the-spot mobile that whole sampler is convenient to; Can measure static pressure in the wind-warm syndrome in an airduct road, wind static pressure and the stopple coupon when accurately gathering coal dust, it is various to measure data.
Description of drawings
Fig. 1 is the structural representation of a kind of intelligent isokinetic sample of pulverized coal device of the utility model.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is elaborated.
As shown in Figure 1, be a kind of intelligent isokinetic sample of pulverized coal device of the utility model, comprise adjustable air pump 7 and the touch formula liquid crystal control operation screen 6 of stopple coupon 1, wind speed compared with control device 2, coal dust disconnecting gear and rotating speed that is connected by pipeline successively, stopple coupon 1 is plugged in airduct road 14, upwards offer in 1 week of stopple coupon over against a plurality of thief hole (not shown)s of a general mood stream, thief hole can also only arrange a thief hole, and the set-up mode of thief hole is that prior art is not given unnecessary details at this.Air pump 7 is sent into wind speed compared with control device 2 after the air-flow in airduct road 14 is drawn by stopple coupon 1, wind speed compared with control device 2 compares the flow velocity of air-flow in the flow velocity of air-flow in the stopple coupon 1 and the airduct road 14, and send steering order to air pump 7, steering order comprises the raising rotating speed, reduces rotating speed, and steering order can send by wired or wireless mode.Air-flow through wind speed compared with control device 2 feeds coal dust disconnecting gear, makes coal dust and burbling, collects coal dust simultaneously.Coal dust disconnecting gear comprises one-level coal dust disconnecting gear 11 and secondary coal dust disconnecting gear 9, and one-level coal dust disconnecting gear 11 adopts cyclone type to separate with secondary coal dust disconnecting gear 9 in the present embodiment, and coal powder collection is in one-level is removed sample bottle 12 and secondary sampling jar 10.Discharge through air pump 7 by filtrator 8 through the air-flow that two-stage is separated.The pipeline that connects wind speed compared with control device 2 and coal dust disconnecting gear is arranged to flexible pipe 3, and be provided with separation valve door 13 near the coal dust disconnecting gear place, coal dust disconnecting gear, air pump and touching control desk 4 are fixed on the transportable frame 6, frame 6 bottoms have roller 10, and move at the scene of being convenient to equipment.The control operation of touch formula liquid crystal is shielded 4 outsides protective cover 5 is installed.
