Please refer to Fig. 3 and Fig. 4, the structural representation of a kind of smoke dust sampling system that Fig. 3 provides for the utility model; Fig. 4 is that the A-A of the smoke dust sampling system in Fig. 3 is to view.
Herein with 32 pairs of sampling pipes, the every group of sampled point 2 perpendicular to flue dust flow direction is sampled as example and describes, and every group of sampled point 2 of the following stated all refers to the combination of some sampled points 2 of arranging perpendicular to flue dust flow direction; And, the vertical flue dust flow direction layout of sampling pipe 32, its movement vertically can be to 2 samplings of every group of sampled point.
In Fig. 3, filled arrows direction is flue dust flow direction.
As shown in Figure 3 and Figure 4, this smoke dust sampling system comprises motor 31 and sampling pipe 32, and the gear mechanism 33 being driven by motor 31, sampling pipe 32 is provided with rack mechanism 320 towards a side of gear mechanism 33, this rack mechanism 320 is axial arranged along sampling pipe 32, be to be understood that, gear mechanism 33 and rack mechanism 320 are after setting completed, the two can fit engagement, so that gear mechanism 33 is when rotate, rack mechanism 320 moves, and drives sampling pipe 32 along its axial synchronizing moving, and sampled point different in each group 2 is sampled.
Above-mentioned motor 31 and gear mechanism 33 all should be arranged on the pedestal of smoke dust sampling system, and the two is relatively fixing; Can process rack mechanism 320 at sampling pipe 32 outer walls, be that sampling pipe 32 main bodys and rack mechanism 320 are one-body molded, also rack mechanism 320 can be fixed on separately on sampling pipe 32, be sampling pipe 32 main bodys and rack mechanism 320 split settings, as long as can make the relative sampling pipe 32 of rack mechanism 320 fixing.
The type of belt drive that rack-and-pinion coordinates relies on entity structure, i.e. gear teeth and rack tooth engagement power transmission, and it has the following advantages:
First, adopt gear teeth and rack tooth engagement power transmission, between the two, there is larger contact area, during transmission, gear mechanism 33 and rack mechanism 320 are stressed evenly, not only be conducive to protect gear mechanism 33, be also conducive to self of sampling pipe 32 that protection is provided with rack mechanism 320, and make sampling process safer reliable;
The second, rely on entity structure power transmission, avoid larger friction force to act on sampling pipe 32, protection sampling pipe 32 is not frayed, extends its serviceable life.
Further, smoke dust sampling system also comprises angle sheave 34, this angle sheave 34 offers recess along circumference complete cycle, simultaneously, sampling pipe 32 is provided with teat 321 towards a side of angle sheave 34, this teat 321 axially has preliminary dimension along sampling pipe 32, its there is appropriate shape and make its can with above-mentioned recess clamping.
For improving kinetic stability and the sampling accuracy of sampling pipe 32, above-mentioned angle sheave 34 plays guiding and supports the effect of sampling pipe 32, due to recess and teat 321 clampings, when sampling pipe 32 moves, between teat 321 and recess, produce friction force, this friction force drives angle sheave 34 to rotate, sliding friction between pressure roller and sampling pipe 32 in background technology relatively, rolling friction forms of motion in this embodiment had both been enough to provide support the acting force of sampling pipe 32, can reduce contact area again as far as possible, thereby reduce the wearing and tearing to sampling pipe 32, further guarantee its serviceable life.
Should be appreciated that above-mentioned teat 321 has preliminary dimension and refers to, this size is enough to make sampling pipe 32 when one group of sampled point 2 of sampling, and its teat 321 clamps with recess all the time.
Certainly, also guide rail can be set, and make teat 321 be clamped in guide rail, still, the contact area of guide rail and teat 321 is larger, and the forms of motion of sampling pipe 32 relative guide rails is sliding friction, and sampling pipe 32 is subject to compared with galling.
Preferably, the number of above-mentioned angle sheave 34 is two, and gear mechanism 33 in the vertical directions are between angle sheave described in two 34, to be uniformly distributed the stress point of sampling pipe 32, as a in Fig. 3, b, c, wherein, a, b represent the Support Position of 34 pairs of sampling pipes 32 of two angle sheaves, and c represents the Support Position of 33 pairs of sampling pipes 32 of gear mechanism.Obviously, a, b two places are to the force direction of sampling pipe 32 and c place to the force direction of sampling pipe 32 contrary (as shown in the arrow at a, b, c tri-places in figure), and according to the layout of Support Position in present embodiment, the force-bearing situation of sampling pipe 32 is best.
Because angle sheave 34 only plays guiding and supporting role, therefore, its number needn't be too much, but may there is again the unstable situation that supports in single angle sheave 34, therefore, when the number of angle sheave 34 is two, can guarantee guide support effect, save again cost.
Certainly, the number of angle sheave 34 also can be for one or more than two, and the position of gear mechanism 33 also can change to some extent, and still, in order to guarantee support effect, its best position should be that in the vertical direction is between each angle sheave 34.
Please refer to Fig. 5, Fig. 5 is the structural representation of the limiting bracket of the smoke dust sampling system in Fig. 3.
On the basis of above-mentioned embodiment, smoke dust sampling system can also have limiting bracket 35, this limiting bracket 35 sampling pipe 32 axially on angle sheave 34 at a distance of preset distance, it has the spacing hole 350 for sampling pipe 32 plug-in mountings, the size of spacing hole 350 should be adaptive with the shape of sampling pipe 32 periphery walls, so that sampling pipe 32 is plugged in after this spacing hole 350, sampling pipe 32 is limited along the displacement of flue dust flow direction, and sampling pipe 32 can not move up perpendicular to its axial side.
Similar to angle sheave 34, limiting bracket 35 plays guide support effect to sampling pipe 32 equally, arrange after limiting bracket 35, two 34 pairs of angle sheaves sampling pipes 32 provide the first heavy support guide, 35 pairs of angle sheaves 34 of limiting bracket provide the second heavy support guide, and sampling pipe 32 is subject to dual guiding, dual support.
Usually, sampling pipe 32 has longer size vertically, angle sheave 34 and limiting bracket 35 are separated after preset distance (this preset distance should be determined according to the length of sampling pipe 32), can take into account to sampling pipe 32 near and away from the support of two ends of flue 1, so that support effect is more reliable, and the combination of angle sheave 34 and limiting bracket 35 also makes guide effect better.
Further, cushion pad 30 can also be set at the butt of sampling pipe 32, this cushion pad 30 radially has preliminary dimension along sampling pipe 32.So, avoid sampling pipe 32 and gear mechanism 33, angle sheave 34 etc. to collide with.
Further, also comprise the telescopic outrigger 37 of support plate 36 and support support plate 36, motor 31, gear mechanism 33 etc. is installed on support plate 36, level meter 38 is also installed, to indicate the levelness of support plate 36 on support plate 36; Telescopic outrigger 37 has Telescopic, and it is flexible to regulate the levelness of support plate 36.
Sampling should regulate the height of supporting leg before starting, and by the levelness of level meter 38 judgement support plates 36, when support plate 36 is during in horizontality, then starts sampling.So, be conducive to guarantee that smoke dust sampling system correctly installs, further guarantee the accuracy of sampled result.
Can also be between motor 31 and gear mechanism 33 connection reducer 39, the rotating speed of motor 31 is generally higher, even if the minimum speed of motor 31 is also higher than the sample rate of sampling pipe 32, arrange after speed reduction unit 39, the rotation of motor 31 can be matched to gear mechanism 33 well, thereby the stable sampling pipe 32 that drives is sampled.
Introduce the specific works process of this smoke dust sampling system below.
Please refer to Fig. 6 and Fig. 7, Fig. 6 is that the sampled point of smoke dust sampling system is arranged schematic diagram; Fig. 7 is a kind of FB(flow block) of embodiment of the method for sampling of the smoke dust sampling system in Fig. 3.
As shown in Figure 6, at the some sampled points 2 of the interior layout of flue 1 to be sampled, each sampled point 2 is divided into some groups, each group is arranged in juxtaposition along flue dust flow direction, the sampled point 2 away from thieff hatch mouth 10 of giving a definition in each group of take is last sampled point 2, the sampled point 2 in the most close sampling aperture 10 is first sampled point 2, and take the sampling process of single group sampled point 2 is described as example.
In order to realize, the robotization of sampling pipe 32 is controlled, can after the sampling that completes a sampled point 2, automatically start the sampling of next sampled point 2, this smoke dust sampling system can also comprise electric machine controller D1, for controlling the startup of motor 31 or stopping, and further drive sampling pipe 32 to move sampling.
Electric machine controller D1 comprises analysis element and executive component, and smoke dust sampling system is sampled to sampled point 2 according to following step:
S1, analysis element are set and are needed to be sampled the sectional dimension L of flue 1, sampled point 2 number M and the sampling time T of described sampling pipe 32 to sampled point described in each 2 of single group;
S2, analysis element calculate by treating sectional dimension L and described sampled point 2 number N of sampling flue 1, obtain described sampled point 2 position M;
S3, executive component are controlled motor 31 according to sampling time T and sampled point 2 position M, to drive sampling pipe 32 to arrive successively sampled point 2 position M, to stop sampling time T;
S4, sampling finish.
The sectional dimension L of flue 1 refers to the sectional dimension of flue 1 vertical flue dust flow direction, as indicated L in figure, along the axial size of sampling pipe 32, so, in conjunction with sampled point 2 number N (as shown in Figure 6, N is 4), just can calculate by simple mathematical formulae the position M of each sampled point 2.
The position M of above-mentioned each sampled point 2 should calculate according to the related specifications in GB GB/T13931-2002, be specially: the coordinate of first determining the sampling aperture 10 of flue 1, afterwards according to calculating each sampled point 2 apart from the distance in this sampling aperture 10, and obtaining the coordinate of each sampled point 2, M comprises the coordinate information of each sampled point 2 of each group.
And, above-mentioned executive component, analysis element all should have the control program being formed by computer programming, sampled point 2 position M, flue 1 sectional dimension L, sampled point 2 number N, residence time T are all pre-stored in sampling pipe 32 controllers as electric signal, the foundation moving with formation control sampling pipe 32, meanwhile, the sampling process of sampling pipe 32 is realized automatically by computer control.
Further, electric machine controller D1 can also comprise detecting element and warning device, in step S3, sampling pipe 32 moves to after each sampled point 2 successively, detecting element all detects the position of sampling pipe 32 head ends, and analysis element is made comparisons described sampling pipe (32) head-end location and the position of last sampled point 2 of single group:
When sampling pipe 32 head ends exceed last sampled point 2 of single group, analysis element forms excess of stroke signal, now turns to step S5:
S5, warning device receive excess of stroke signal, and report to the police, and sampling finishes.
If analysis element does not form excess of stroke signal, sampling pipe 32 head ends do not exceed last sampled point 2 position of single group, and sampling pipe 32 stops sampling time T, and sampling is normally carried out.
Should be appreciated that above-mentioned sampling pipe 32 head ends exceed single last sampled point 2 of organizing and refer to, sampling pipe 32 moves to each sampled point 2 successively according to sampling routine, in this process, surpasses last sampled point 2 according to the path movement forming.
In smoke dust sampling process, sampling pipe 32 excess of stroke will cause sample error, if do not find in time, and take measures, and will obtain wrong sampled result, even damage the structure of sampling system.Present embodiment avoids above-mentioned phenomenon to occur, and each movement of sampling pipe 32 is all carried out to excess of stroke detection, once sampling can be found and stop to the excess of stroke in time, avoids occurring sampling accident.
Please refer to Fig. 8, Fig. 8 is the FB(flow block) of the second embodiment of the method for sampling of the smoke dust sampling system in Fig. 3.

S20, starter motor 31, drive sampling pipe 32 head ends to move to the sampling aperture 10 of flue 1;
S21, detecting element detect described sampling pipe 32 head-end location;
S22, analysis element be the position of sampling pipe 32 head ends and the position in sampling aperture 10 relatively, and judges whether sampling pipe 32 head ends arrive sampling aperture 10:
To turn to step S221:
S221, send zeroing complete signal to executive component, turn to step S3;
No, turn to step S222:
S222, send the signal that do not return to zero to executive component, turn to step S20
Start, before sampling, first the position of sampling pipe 32 to be adjusted, when sampling pipe 32 head ends arrive sampling aperture 10, sampling is moved in the sampling location that sampling pipe 32 just starts to calculate according to computing element; If sampling pipe 32 head ends do not arrive sampling aperture 10, this smoke dust sampling system will continue zeroing, until sampling pipe 32 head ends arrive sampling aperture 10.
In this embodiment, increase zeroing step, to before 2 samplings of every group of sampled point, all sampling pipe 32 head ends are adjusted to sampling aperture 10, after adjustment, before each group sampled point 2 samplings, sampling system all has identical original state, is conducive to guarantee respectively to organize sampled point 2 samplings accurately; And sampling aperture 10 is generally positioned at flue 1 and extraneous contact position, its positional information more easily obtains, and also easily observation directly perceived, compares compared with other positions, is more suitable for as zeroing benchmark.
Please refer to Fig. 9, Fig. 9 is the FB(flow block) of the third embodiment of the method for sampling of the smoke dust sampling system in Fig. 3.
