Fixing coal fines sampling apparatus is for coal dust sampling special equipment on wind powder feeding pipes of pressurized direct pulverizing coal system. In the variation of the wearing and tearing of coal pulverizer abrasive article, coal, lumpiness, the fineness of coal dust will produce larger variation, and this will directly affect the efficiency of combustion of boiler, increases the cost of generating, and therefore regularly the sampling of fineness of pulverized coal being detected is a very important job. And detect by the sampling of fineness of pulverized coal, can learn in time whether fineness of pulverized coal exceedes design load, be folded to an aperture so that adjust in time, change coal pulverizer abrasive article or adjust separator, reach designing requirement to realize fineness of pulverized coal. And traditional coal powder sampler, because location, probe tube position is inaccurate, the sample taking out is not representative; Probe tube improper use causes that to block even the life-span short, has additionally increased operation cost, and cyclone separator is directly connected with sampling bottle, and sealing not exclusively, easily causes leakage powder in the time of sampling, pollutes working environment, and the Long-term Effect staff's is healthy.
Utility model content
The poorly sealed reality that the utility model exists for prior art easily causes Lou powder, porous probe tube location inaccuracy, makes the not representative problem of sample, proposes following technical scheme:
Hidden arm-type coal fines sampling apparatus, comprise: compressed air adapter, compressed air valve, pressure regulator valve, the air ejector of emanating, blow down valve, porous probe tube, sampling operation bar, shell body, sample valve, sampling bottle, cyclone separator, the air ejector one end of emanating is connected with pressure regulator valve by articulation, the other end is connected with shell body by blow down valve, bend pipe, cyclone separator one end is connected with the air ejector of emanating is vertical by articulation, and the other end is connected with shell body by sample valve, pipeline; It is characterized in that: described sampling bottle and cyclone separator junction are provided with sealing ring, described sampling operation bar and shell body junction are provided with positioning disk, described positioning disk is gear disk, described positioning disk is provided with locating clip, described locating clip comprises fixation kit and movable component, the fixation kit of described locating clip is connected with positioning disk by rotating shaft, the gear phase embedding complementation on movable component end and positioning disk, and described shell body is vertically mounted on pulverized coal channel by set bolt and welded flange.
Further, in order to strengthen the sealing of sampling bottle device, prevent the pollution of the working environment that the leakage of coal dust causes, described sampling bottle and cyclone separator junction are provided with sealing ring, and its material is rubber.
The utlity model has following beneficial effect:
The utility model is in operating process, and the leakage of coal dust has effectively been avoided in the sealing by rubber ring to sampling bottle and cyclone separator in sampling process, has protected working environment, reduces unnecessary workload; The utilization of positioning disk, not only make porous probe tube accurately sample, the coal dust taking out is representative, allow staff in time according to the variation adjustment of fineness of pulverized coal, replacing coal pulverizer abrasive article, thereby reduce unnecessary wearing and tearing and reduced the fault rate of installing, and simple to operate, locating effect is accurate, can the judgement to pulverized coal particle because of the cause influence staff of sampling result, when greatly having improved the efficiency of boiler combustion, alleviate staff's workload, and then increase work efficiency.

Fig. 2 is the structural representation of hidden arm-type coal dust device positioning disk.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further:
As shown in Figure 1 and Figure 2, hidden arm-type coal fines sampling apparatus, comprise: compressed air adapter 1, compressed air valve 2, pressure regulator valve 3, the air ejector 5 of emanating, blow down valve 6, porous probe tube 7, sampling operation bar 8, shell body 9, sample valve 10, sampling bottle 11, cyclone separator 12, air ejector 5 one end of emanating are connected with pressure regulator valve 3 by articulation 4, the other end is connected with shell body 9 by blow down valve 6, bend pipe, cyclone separator 12 one end by articulation 4 with emanate that air ejector 5 is vertical to be connected, the other end is connected with shell body 9 by sample valve 10, pipeline; It is characterized in that: described sampling bottle 11 is provided with sealing ring 15 with cyclone separator junction, described sampling operation bar 8 is provided with positioning disk 13 with shell body 9 junctions, described positioning disk 13 is gear disk, described positioning disk 13 is provided with locating clip 14, described locating clip 14 comprises fixation kit and movable component, the fixation kit of described locating clip 14 is connected with positioning disk 13 by rotating shaft, gear phase embedding complementation on movable component end and positioning disk 13, described shell body 9 is vertically mounted on pulverized coal channel by set bolt and welded flange.
In order to strengthen the sealing of sampling bottle device, prevent the pollution of the working environment that the leakage of coal dust causes, described sampling bottle and cyclone separator junction are provided with sealing ring 15 and strengthen sealing, and its material is rubber.
Hidden arm-type coal fines sampling apparatus utilizes negative pressure axle to absorb differentiation mixture to be pumped out from pulverized coal channel and carry out solid and gas with cyclonic separation principle and separates and succeed in developing. in sampling process, probe tube 7 gos deep in pulverized coal channel for launching, all valves are opening, when compressed air passes through from outlet pipe the air ejector 5 of emanating, its jet action must cause cyclone separator 12, probe tube 7, sampling bottle 11 parts such as grade produce negative pressure, impel the primary mixture in pulverized coal channel to enter sampler along probe tube 7, primary mixture carries out solid and gas separation in cyclone separator 12, isolated coal dust falls into the sampling bottle 11 below cyclone separator, gas compressed air aspirates from newly sending as pulverized coal channel, whole operating process does not produce pollution to workplace, before sampling, compressed air regulating valve is adjusted, can realize isokinetic sampling, make the coal dust sample of taking-up representative.
When sampling, open compressed air control valve 2, according to the manometer on pressure regulator valve 3, compressed air pressure is adjusted to required pressure limit; Pull sampling operation bar 8, porous probe tube 7 is deployed in pulverized coal channel and makes thief hole just to coal dust traffic direction, regulate the locating clip on positioning disk, it is imbedded mutually and the position of fixing porous probe tube 7 with the gear on gear disk, reach accurate location, make the sample of taking-up representative, open blow down valve 6, sample valve 10, sampling starts, 2 to 4 minutes time, closes compression air shut-off valve 2, blow down valve 6, sample valve 10; Pull action bars 8, porous probe tube 7 is hidden in shell body 9, take off sampling bottle 11, coal dust sample is taken out and sampling bottle is replaced and noted the sealing of interface sealing ring. In order to prevent the obstruction of probe tube 7, need to purge it. When purging, open compressed air control valve 2, shut-down purge valve 6, opens sample valve 10, and compressed air will purge probe tube by sample valve 10, thereby ensures that probe tube 7 samples the unobstructed of work, avoids stopping up; While sampling, pull sampling operation bar 8, porous probe tube is hidden in shell body 9, extend the service life of porous probe tube.
The above; it is only detailed description of the invention of the present utility model; but the protection domain of utility model is not limited to this; in the technical scope that any those of ordinary skill in the art disclose at the utility model; the variation that can expect easily or replacement, within all should being encompassed in the protection domain of utility model.
