Description
Technical field
The utility model relates to coal fines sampling apparatus, particularly relates to a kind of push-in type coal fines sampling apparatus.
Background technology
Push-in type fixes coal fines sampling apparatus, is coal dust sampling specialized equipment on pressurized direct pulverizing coal system First air powder feeding pipes.In coal pulverizer day-to-day operation, the change of the wearing and tearing of coal pulverizer abrasive article, coal, lumpiness, fineness of pulverized coal will produce larger change, directly affect boiler combustion efficiency, increase cost of electricity-generating, therefore regular to fineness of pulverized coal sampling detection, when fineness of pulverized coal exceedes design load, timely adjustment, replacing coal pulverizer abrasive article or adjustment separation vessel are folded to an aperture, reach designing requirement to realize fineness of pulverized coal.
Coal fines sampling apparatus principle is, and to take pressurized air as power aspirate into negative pressure through air ejector by sampling jar and separation vessel, make coal dust from pipeline, be inhaled into stopple coupon to enter cyclone separator and carry out solid and gas separation, coal dust is thrown to wall by swirling eddy because of Action of Gravity Field, then falls into sampling jar by Action of Gravity Field.Gas after separation to rise top along middle of the road, discharges from gas outlet, top, again sends into pulverized coal channel through the suction of emitter air ejector, realizes being separated of coal dust and gas.Only need shake during sampling when stopple coupon is sent into and do not sampled by gearing and exit in pulverized coal channel.Sampling terminates rear closedown sealed valve.
At present, coal fines sampling apparatus has various, has cantilevered, scroll casing type, portable etc., but in real work, more than there is its shortcoming, during use, easily block, thus causing easy damage, the life-span is short, secondly, breeching environment is different, the concrete coal fines sampling apparatus adopted also is different, so duration leaks, then samples imperfect.
Utility model content
Easily block to solve existing coal fines sampling apparatus, the life-span is shorter, and the problems such as leakage, breeching environmental constraints and its singularity, propose a kind of push-in type coal fines sampling apparatus.
The utility model adopts following technical scheme:
Push-in type coal fines sampling apparatus, comprise pulverized coal channel, sampling jar, cyclone separator, emitter air ejector, sample valve, pressure regulator valve, compressed air valve and handwheel, the right side of described pulverized coal channel is connected to and is provided with ball valve and transmission tube, described ball valve is provided with vertical fixed head, and transmission tube is fixedly connected with fixed head by flange, and the right-hand member that transmission tube is logical is handwheel; Be connected at the stopple coupon that passes on left of ball valve right-hand member with blow down valve and sample valve, the right side of blow down valve is connected with emitter air ejector left end, and the right-hand member of emitter air ejector is connected with pressure regulator valve left end, and pressure regulator valve right-hand member is connected with compressed air valve; The lower end of described emitter air ejector is provided with cyclone separator, and cyclone separator left end is connected with sample valve right-hand member, and the below of cyclone separator is provided with sampling jar; Fixed mount is provided with between stopple coupon and transmission tube.
Further, described ball valve is in the centre position of pulverized coal channel.
Further, described pressure regulator valve is provided with tensimeter.
The utility model has following beneficial effect:
1. product sampler adopts stainless steel to make, and outward appearance is neatly small and exquisite, and whole service life is long.
2. structure is simple, and gear train flexible operation, not bite, sample simple and convenient.
3. adopt telescopic, can fix a point or multiple spot, isokinetic sampling, the coal dust sample of taking-up is representative.
4. pressurized air can be adopted to purge stopple coupon, avoid coal dust to block stopple coupon.
5. the packoff sealing be fixedly mounted on pulverized coal channel is tight, and coal dust free leaks, and does not pollute working environment.
6. insert in pulverized coal channel when stopple coupon uses, can exit outside pulverized coal channel when not sampling, avoid washing away of breeze airflow, long service life.
Accompanying drawing explanation
Fig. 1 is push-in type coal fines sampling apparatus structural drawing.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
As described in Figure 1: push-in type coal fines sampling apparatus, comprise pulverized coal channel, sampling jar 10, cyclone separator 11, emitter air ejector 12, sample valve 9, pressure regulator valve 2, compressed air valve 13 and handwheel 1, the right side of described pulverized coal channel is connected to and is provided with ball valve 6 and transmission tube 4, described ball valve 6 is provided with vertical fixed head 5, and transmission tube 4 is fixedly connected with fixed head 5 by flange, and the right-hand member that transmission tube 4 is logical is handwheel 1; Be connected at the stopple coupon 7 that passes on left of ball valve 6 right-hand member with blow down valve 3 and sample valve, the right side of blow down valve 3 is connected with emitter air ejector 12 left end, and the right-hand member of emitter air ejector 12 is connected with pressure regulator valve 2 left end, and pressure regulator valve 2 right-hand member is connected with compressed air valve 13; The lower end of described emitter air ejector 12 is provided with cyclone separator 11, and cyclone separator 11 left end is connected with sample valve right-hand member, and the below of cyclone separator 11 is provided with sampling jar 10; Fixed mount 8 is provided with between stopple coupon 7 and transmission tube 2; Described ball valve 6 is in the centre position of pulverized coal channel; Described pressure regulator valve 2 is provided with tensimeter.
Before sampling, all valves are closed condition, first open sealed valve shake handwheel 1 and are advanced in pulverized coal channel by stopple coupon 7, then open compressed air valve 13; According to tensimeter display adjustment compressed air pressure regulating valve, compressed air pressure is adjusted to required pressure limit (0.05-0.1MPa).Regulate during pressure regulator valve 2 and first the knob on pressure regulator valve will be extracted by twisting clockwise as increasing pressure, otherwise reduce, be transferred to after required pressure at push-turn key.Then sample valve 9 is opened; Stopple coupon 7 is purged, all will once purge after every sub-sampling terminates; Purge time 1-2 minute; Then blow down valve 3 is opened; Shake handwheel 1; By stopple coupon 7, transmission tube 4 simultaneously slowly push in pulverized coal channel; Sampling starts, and is slowly exited outside pulverized coal channel by stopple coupon when stopple coupon 7 pushes and puts in place again.Close seal valve, closes compression air shut-off valve, blow down valve, sample valve; Take off sampling jar 10; Coal dust sample is taken out and replaced by sampling jar and notes the sealing of interface, whole sampling terminates.
