Description

A kind of unslaked lime material sampling thief

Technical field

The utility model relates to power domain, particularly relates to a kind of unslaked lime material sampling thief for calcium lime powder Quality Detection in electric power dry desulfurization device.

Background technology

Sampler can be used for the media for heat exchanges such as the higher liquids and gases of temperature, mostly temperature is higher for water in boiler and therrmodynamic system, and high water temperature is not easy to sampling and measuring chemical examination, so should be cooled in sampling, namely the sample introduction sampling cooler of sampling spot is cooled, during sampling, General Requirements guaranteed flow is when 500-700mL/min, and sample coldly can get less than 30-40 DEG C, meets the standard of power industry DL/T457-91.Such as, coal powder sampler can be used for regular coal dust sampling on unit pulverized-coal system First air pulverized coal channel, with pressurized air be power source can the sampler run of free of discontinuities.

Authorization Notice No. is CN203981428U, the patent No. be 201420185021.0 Chinese patent disclose a kind of sampling thief, comprise interior pipe and outer tube, described interior pipe is arranged on outer tube, interior pipe plugs with outer tube and is connected, described interior pipe and outer tube are equipped with grooving, and the length of described outer tube grooving is 3/4 of outer length of tube; The girth of described outer tube grooving is 3/5 of outer tube girth; The length of described interior pipe grooving is 3/4 of inner tube length; The girth of described interior pipe grooving is 3/5 of interior pipe girth.The problem that this patent pipe mainly solves is, closes to close into a pipe and sample after can rotating 180 ° within the outer tube with outer tube, and structure is simple, easy to operate; Meanwhile, this structure by the impact of moisture content of material, can not sampled by any material, can be improved the accuracy of sampling widely.But this structure clearly only can extract a sample, cannot realize stratified sampling.

This case is innovated according to the feature of prior art and above-mentioned announcement, because existing universal sample device only can extract a sample, cannot carry out stratified sampling to the material in tank car.Therefore, for above aspect, need reasonably to improve prior art.

Utility model content

For above defect, the utility model provides the unslaked lime material sampling thief that a kind of handling safety is convenient, structure simple, can carry out stratified sampling, can improve calcium lime powder material Detection job, to solve many deficiencies of prior art.

For achieving the above object, the utility model is by the following technical solutions:

A kind of unslaked lime material sampling thief, comprise outer sleeve and inner sleeve, the peripheral mounting knob of each sleeve, described outer sleeve outside surface offers some sample window I, inner sleeve outer surface offers some sample window II, and this inner sleeve inserts outer sleeve inside and two the back-to-back directions of sample window keeping the same position of inner sleeve and outer sleeve corresponding;

Interval between every two adjacent sample window I and between every two adjacent sample window II is 200mm, and the window length and width of each sample window respectively is 50mm, 20mm.

Correspondingly, by rotating handles, make inner sleeve rotate 180 ° relative to outer sleeve, the sample window of inner sleeve and outer sleeve overlaps.

After overlapping, material fully enters inner sleeve inside by sample window, and then by rotating handles, makes inner sleeve rotate 180 ° relative to outer sleeve.

The beneficial effect of unslaked lime material sampling thief described in the utility model is:

Change can only singlely sample in the past, can not stratified sampling, sample uneven disadvantage, adopt double-jacket tube multiwindow sampling structure, interior pipe and outer tube can be movable relatively, plug is flexible, and this structure operation safe and convenient, structure be simple, can carry out stratified sampling, can improve calcium lime powder material Detection job.

Accompanying drawing explanation

With reference to the accompanying drawings the utility model is described in further detail below.

Fig. 1 is the outer sleeve structure schematic diagram of unslaked lime material sampling thief described in the utility model embodiment;

Fig. 2 is the inner sleeve structure schematic diagram of unslaked lime material sampling thief described in the utility model embodiment.

In figure:

Embodiment

As shown in Figure 1-2, unslaked lime material sampling thief described in the utility model embodiment, comprise outer sleeve 1 and inner sleeve 2, the peripheral mounting knob 5 of each sleeve, described outer sleeve 1 outside surface offers some sample window I3, inner sleeve 2 outside surface offers some sample window II 4, this inner sleeve 2 inserts outer sleeve 1 inside and two sample windows keeping inner sleeve 2 corresponding with the same position of outer sleeve 1 stagger 180 °, namely two sample windows back-to-back, to guarantee that the granular material thief hatch do not had on sleeve enters inner sleeve 2, then sampling thief is vertically inserted in tank car, then, by rotating handles 5, inner sleeve 2 is made to rotate 180 ° relative to outer sleeve 1, now, inner sleeve 2 overlaps with the sample window of outer sleeve 1, stops and within 5-10 minute, makes material in tank car fully enter inner sleeve 2 inside by sample window, and then by rotating handles 5, make inner sleeve 2 rotate 180 ° relative to outer sleeve 1, sampling thief is taken out by tank car, can sampling work be completed.

Unslaked lime material sampling thief described in above the utility model embodiment, φ 42 stainless-steel tube and φ 34 stainless-steel tube double-jacket tube is used to make, interval between every two adjacent sample window I3 and between every two adjacent sample window II4 is 200mm, the window size of each sample window is 20 × 50mm, and sampling thief length exceeds tank car cloth bag diameter.Principle of work is: first sampling thief is rotated 180 ° before use by close, sampling thief is inserted bottom tank car cloth bag, then sampling thief is rotated 180 ° window is opened, ash collector window is closed after sampling thief being rotated 180 °, then extract ash collector out ash collector is kept flat ground to open, pour out every layer of grey sample.

The above-mentioned description to embodiment can understand and apply this case technology for the ease of those skilled in the art, person skilled in the art obviously can make various amendment to these examples easily, and General Principle described herein is applied in other embodiment and need not through performing creative labour.Therefore, this case is not limited to above embodiment, and those skilled in the art is according to the announcement of this case, and the improvement made for this case and amendment all should in the protection domains of this case.
