Abstract
The utility model discloses a smoke sampler fixing device which comprises a flange and a clamping buckle; the flange is designed in a manner of being matched with another flange at a flue sampling opening; one end of the clamping buckle is fixed on the first flange through a pin shaft, and the other end of the clamping buckle is free; the free end is fixed by a screw. The smoke sampler fixing device is characterized in that during sampling, all that is needed is to mount a smoke sampling pipe fixing device at a sampling opening, assemble a smoke sampling pipe and close the clamping buckle, and then sampling can be performed voluntarily, so that the former sampling manner that an operator needs to hold by a hand can be changed, not only is manpower saved, but also the stability of sampling equipment is improved, errors caused by undulating of hand-holding can be reduced effectively, and leakage of smoke at the sampling opening can be controlled effectively. The device has the advantages of unique design, low cost and easiness in popularization.
Description
Technical field
The utility model relates to the atmosphere detection field, especially relates to a kind of smoke dust sampling instrument stationary installation.
Background technology
Thief hatch design on general factory flue is very simple, opening part connects one section steel pipe, and top dress perforate flange and blind flange are opened during sampling after blind flange stretches into soot sampling tube and needed artificial hand-held 30～40min to sample, and contain a large amount of highdensity toxic and harmfuls in flue dust, and as: SO
2, H
2S, CO
2, NOx, HCl, serious harm sample collector healthy, in addition, in flue, the different loci flue gas flow rate is all different, require sampling pipe to keep transfixion at flue while therefore sampling, if adopt manually hand-heldly, inevitably fluctuation can bring larger error, therefore need to improve existing sampling apparatus.
The utility model content
The utility model needs the hand-held error that easily causes for solving present smoke dust sampling, and the healthy problem of harm sample collector, a kind of thief hatch that soot sampling tube can be fixed on is provided, and has not needed hand steered stationary installation.
For reaching above-mentioned effect, design proposal of the present utility model is that design is a kind of firm in structure, with low cost, the smoke dust sampling instrument stationary installation of easy operating, is characterized in that, described flange is fixed on the reservation flange of flue gas sampling mouth, one end of described clip is fixed on flange by bearing pin, described soot sampling tube passes clip and two flanges stretch in flue, with screw, described clip is fixed, and then the fixed sample pipe.
The model size of described flange, the punch position size is consistent with the reservation flange on the flue gas sampling mouth.
It is fixing with bearing pin 2.1 that clip must be arranged to an end, and an end is designed to the expandable survivor of a murder attempt.
The size of described clip mesopore is advisable can step up soot sampling tube after fastening.
Described clip survivor of a murder attempt end arranges screw thread mouth, is used for fixed screw 2.2 and tightens clip.
Described flange, clip, bearing pin are stainless steel.
For better fixed sample pipe, further preferred technical scheme has, and described clip circular arc inwall arranges densely covered lines, increases the friction between clip and sampling pipe.
Although the clip with lines can not slide by the fixed sample pipe in the vertical direction, but in flue, that sampling pipe is not stopped is moving in the impact of high flow rate flue gas, change the thief hatch flow velocity, affect testing result, further preferred technical scheme also has, the design thickness of described clip is at least greater than soot sampling tube external diameter 10mm, to guarantee fixing sampling pipe.
For guaranteeing flange and other structure energy tight closure, reduce the leakage of flue dust, in addition, described flange two sides polishes smooth further preferred technical scheme, the gap after the minimizing closure.
The beneficial effects of the utility model are: the utility model design is ingenious, only need, at thief hatch, a stationary installation is installed, just can effectively prevent overflowing of toxic and harmful, fixed sample pipe well, when reducing sample-grabber's labour intensity, guaranteed the accuracy of sampled data, installation cost is cheap, simple to operate, be easy to promote.
Description of drawings
The utility model will illustrate by example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is the utility model schematic diagram;
One of Fig. 2 the utility model flue dust collector stationary installation detail view;
Two of Fig. 3 the utility model flue dust collector stationary installation detail view.
In figure: 1, flange; 2, clip; 2.1, bearing pin; 2.2, fixed screw; 3, flue gas sampling mouth; 4, reserve flange; 5, soot sampling tube.
Embodiment
Disclosed all features in this instructions, or the step in disclosed all methods or process, except mutually exclusive feature and/or step, all can make up by any way.
Disclosed arbitrary feature in this instructions (comprising any accessory claim, summary and accompanying drawing), unless special narration all can be replaced by other equivalences or the alternative features with similar purpose.That is, unless special narration, each feature is an example in a series of equivalences or similar characteristics.
As shown in Figure 1, flue dust collector stationary installation, comprise flange 1 clip 2, and described flange 1 is fixed on the reservation flange of flue gas sampling mouth, and described clip 2 arranges bearing pin 2.1 and is fixed on flange 1, with described fixed screw 2.2, tightens clip.
Concrete installation process, unload the blind flange of lower flue thief hatch during sampling, described flange is screwed on the reservation flange of flue thief hatch, one end of described clip is connected bearing pin and is connected with flange, described clip other end opening, be survivor of a murder attempt's state, described sampling pipe, for becoming the radius column type, can easily pass through described clip.Described sampling pipe is held with the survivor of a murder attempt of fixed screw clamping clip after entering the flue certain depth by flange hole, tighten until sampling pipe is steadily fixed by clip, during sampling, the workman can leave the thief hatch certain distance and operates, avoiding being subject to overflowing flue dust poisons, a sampled point collection is completed, by unscrewing fixed screw, the penetration depth of mobile sampling pipe, carry out the collection of other sampled point.
For protection sample collector's handling safety, avoid the murder by poisoning of excessive flue gas, whole installation process need be worn respirator.
The utility model designs ingenious, only needs install a flue dust collector stationary installation additional at thief hatch, just can effectively reduce leaking outside of flue gas, stablizes sampling pipe,, without hand held type sampling, increases when detecting degree of accuracy, and saving is artificial, is easy to promote.
The utility model is not limited to aforesaid embodiment.The utility model expands to any new feature or any new combination that discloses in this manual, and the arbitrary new method that discloses or step or any new combination of process.
