Abstract
The invention discloses air exhaust type sand collecting system. It includes shell, inner sampling pipe. The shell is set sand bed face plate. The sampling pipe is superposed by twenty rectangular tubes. And its two sides are glued metal screen. And the metal screen and the shell are form flow path. The top of the shell is set ventilator. The ventilator is connected to induced-draft fan. Volume damper is set between them. The bottom of the shell is set sand storing storehouse. The inlet of the sampling pipe is set many pressure taking ports with equidistance. The pressure taking ports are connected to incline type liquid column differential draft gauge. The invention can make all sampling pipes close to equal power air exhaust state by adjusting grass bleed air flow, meanwhile gain many sampling data. It has simple structure, convenient adjusting, strict demand for flow type, and strong adaptability.
Description
Technical field
The present invention relates to the gathering-device of in a kind of gas-solid particle diphasic flow solid particle accurately being sampled, particularly a kind of gas exhausting type vertical sand collecting system, sampling when this system is particularly useful in the husky wind-tunnel differing heights place grains of sand.
Background technology
The vertical sand collecting instrument is placed in the air-flow as a kind of direct surveying instrument, and the air-flow that enters sand-taped instrument is had the stagnation effect, also can produce interference near the flow field it, and receiving husky efficient will descend.In order farthest to avoid the influence of instrument to flowing, a kind of power sand-taped instrument that waits is devised, and this is a kind of sand-taped instrument that has extract system, is also referred to as active sand-taped instrument.The bleeder sand-taped instrument has very high collection efficiency on principle, but present existing bleeder sand-taped instrument has only single hose and the independent bleeder of multitube.The bleeder sand-taped instrument of single hose can only be measured a bit at synchronization, and multibarrel bleeder sand-taped instrument is to the independent bleeding regulating of every pipe owing to adopting, its adjustment process complexity, and the time is long, and having limited the pipe number can only be in several scope.
Summary of the invention
For the convenience of taking into account Measurement Resolution (being number of sampling) and regulating, the objective of the invention is to propose a kind of gas exhausting type vertical sand collecting system, this sand collecting system can in height have higher resolution, can make the rate of air sucked in required in all stopple coupons can both approachingly wait dynamic regime by simple adjusting again, to realize quick and to measure accurately.
In order to realize above-mentioned task, the technical solution that the present invention takes is: this bleeder sand collecting system comprises a shell and inner stopple coupon, shell is arranged on the husky bed surface, it is characterized in that, described stopple coupon is that many square tubes are laminated, two sides of stopple coupon are posted between this metal screen of metal screen of efficient low-resistance and the shell and are left distance, form flow channel; The top of shell is useful on the ventilating opening that connects induced draft fan, between ventilating opening and the induced draft fan volume damper is arranged, and the bottommost in the shell leaves sand storehouse; Equidistantly in the porch of stopple coupon be provided with a plurality of pressure tappings, this pressure tappings is connected with tilting fluid column differential manometer.
Gas exhausting type vertical sand collecting system of the present invention, can be by regulating stopple coupons that a total rate of air sucked in required makes all height all near power such as the grade state of bleeding, obtain the sampled data of a plurality of height simultaneously, simple in structure, easy to adjust, employed principle is not strict with liquid form, and adaptability is strong.

Fig. 1 is the structure diagram of gas exhausting type vertical sand collecting device, and wherein (a) is front view, (b) is the vertical view of (a).
Fig. 2 is the system construction drawing of gas exhausting type vertical sand collecting device.
Label among the figure is respectively: 1, husky bed surface, 2, stopple coupon, 3, metal screen, 4, ventilating opening, 5, shell, 6, sand storehouse, 7, pressure tappings, 8, volume damper, 9, induced draft fan, 10, tilting fluid column differential manometer.
The present invention is further described below in conjunction with accompanying drawing.
Embodiment
Referring to Fig. 1~2, gas formula vertical sand collecting system of the present invention comprises a shell 5, there is stopple coupon 2 shell 5 inside, shell 5 is arranged on the husky bed surface 1, stopple coupon 2 is that 20 square tubes are laminated (certainly according to the actual conditions setting more or be less than 20 square tube), the metal screen 3 of efficient low-resistance is posted in two sides of stopple coupon, leaves distance between this metal screen 3 and the shell 5, forms flow channel; The top of shell 5 is useful on the ventilating opening 4 that connects induced draft fan 9, between ventilating opening 4 and the induced draft fan 9 volume damper 8 is arranged, and the bottommost in the shell 5 leaves sand storehouse 6; Be provided with a plurality of pressure tappings 7 in that the inlet of stopple coupon 2 is equidistant, this pressure tappings 7 is connected with tilting fluid column differential manometer 10.
Wide * height * the wall thickness of stopple coupon 2 employings is that the thin-wall stainless steel of 20mm * 10mm * 0.6mm is made, 20 stacked being arranged in the shell 5 of square tube, the ratio of the area of the filter screen 3 of stopple coupon 2 both sides and the inlet area of stopple coupon 2 is greater than 20, to reduce the resistance that air-flow passes filter screen, to bleed simultaneously is arranged in the top of sand-taped instrument, all is tending towards waiting dynamic regime with the rate of air sucked in required of the inhomogeneous promotion differing heights that utilizes pressure distribution.
The principle of work of its system is, during use with (outlet) shutoff of stopple coupon 2, after containing husky air-flow and entering stopple coupon 2, air passes filter screen 3 and enters the formed passage in gap between filter screen 3 and the shell 5, ventilating opening 4, volume damper 8 through the top are entered atmosphere by induced draft fan 9 extractions, and the grains of sand are trapped in the stopple coupon 2.Adjust volume damper 8 and can adjust the exhausting amount of all stopple coupons 2.
In Fig. 2, the pressure tappings 7 of the porch of stopple coupon 2 and the static pressure in the wind-tunnel are removed and are connected respectively to the two ends of a tilting fluid column differential manometer 10, the angle of inclination of differential manometer is 5 degree, rate of air sucked in required by one can fine adjusting volume damper 8 control.When the bleeding regulating amount made the static pressure at sand-taped instrument device portal place identical with static pressure in the wind-tunnel, then all stopple coupons 2 all were tending towards waiting the power collection status, can collect all data of 20 square tubes simultaneously.
