Description
Technical field
The utility model relates to a kind of layered sampler used when trichlorosilane raw materials for production (metallic silicon power) incoming inspection, belongs to detection technique field.
Background technology
Trichlorosilane is the important source material of producing polysilicon, along with polysilicon is in the widespread use in the fields such as modern science and technology, national defence, industry, the production of trichlorosilane have also been obtained fast development, improves the quality of products, reduces production cost, expanding production capacity becomes the target that each manufacturer competitively chases.
Find in actual production process, the raw materials for production of trichlorosilane, namely the serviceable life impact of quality on the output of trichlorosilane and trichlorosilane synthetic furnace of metallic silicon power is very large.If silica flour is off quality, not only can affect the reaction velocity of synthetic furnace, reduce trichlorosilane output, but also synthetic furnace overtemperature can be caused to damage, production can not be carried out smoothly, thus add the production cost of product.Therefore, the incoming test of the necessary reinforcement metal silica flour of manufacturing enterprise, prevents defective silica flour from flowing into production line.Comprehensively, the quality of metallic silicon power is analyzed exactly, need to carry out stratified sampling to the silica flour of bag inside, and can not mix mutually between each layer silica flour, but existing sampler can only realize single-point sampling, want to realize stratified tests, just repeatedly must sample, which adds the complexity of operation, reduce the incoming test efficiency of silica flour.
Utility model content
The purpose of this utility model is the drawback for prior art, provides a kind of silica flour sampler that can realize stratified sampling, to improve the incoming test efficiency of silica flour.
Problem described in the utility model realizes with following technical proposals:
A kind of silica flour sampler, formation comprises outer tube and inner sleeve, the front end of described outer tube is taper, its tube wall side is provided with the multiple charging holes arranged along its axis direction, described inner sleeve coaxial package is in outer tube, its rear end is positioned at outer tube outside, and the tube wall of inner sleeve is provided with multiple with the multiple charging holes charging aperture one to one on outer tube, and the inside of each charging aperture is equipped with independently sample chamber.
Above-mentioned silica flour sampler, the rear end of described inner sleeve is provided with operating grip.
Above-mentioned silica flour sampler, each sample chamber is surrounded with the two pieces of dividing plates perpendicular to inner sleeve axis being installed on inner sleeve inside jointly by the tube wall of inner sleeve.
Above-mentioned silica flour sampler, the outer wall of described outer tube and inner sleeve is provided with mutually corresponding centering graticule.
Above-mentioned silica flour sampler, described inner sleeve and outer tube clearance fit.
The utility model utilizes the multiple charging holes on outer tube to sample simultaneously, and is left in respectively by sample in the multiple sample chambers in inner sleeve, greatly reduces the complexity of multilayer sampling operation, improves silica flour incoming test efficiency.In addition, the utility model also has the advantages such as structure is simple, with low cost, easy to use, durable in use.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structure after removing outer tube.
In figure, mark is as follows: 1, outer tube, and 2, charging hole, 3, centering graticule, 4, inner sleeve, 5, operating grip, 6, sample chamber, 7, dividing plate.
Embodiment
Referring to Fig. 1, the utility model mainly comprises outer tube 1, inner sleeve 4, operating grip 5 and dividing plate 7.Be clearance fit between internal and external casing, can relatively rotate.The front end (namely inserting one end of silica flour) of outer tube 1 is taper, be convenient to insert silicon powder layer, outer tube 1 side is uniform-distribution with several charging holes 2, sample chamber 6 one_to_one corresponding of charging hole 2 and equal number on inner sleeve 4, sample chamber is storage bin, can store a certain amount of silica flour, silica flour can enter sample chamber by charging hole 2, analyzes for laboratory.By rotating the operating grip 5 on inner sleeve 4, feed bin can be opened or closed.The length of this device and the number of charging hole and pitch-row can be selected as required.
Before sampling, first rotating operating handle 5, inner sleeve 4 is rotated in outer tube 1, sample chamber 6 on inner sleeve 4 is closed (namely charging hole 2 is not relative with the charging aperture on inner sleeve 4), then insert in silica flour by sampler, after reaching designated depth, rotating operating handle 5 opens sample chamber 6(and charging hole 2 is relative with the charging aperture on inner sleeve 4), wait a moment, to enter behind sample chamber 6 rotating operating handle 5 again until silica flour and close sample chamber 6, finally sampler is extracted and namely complete sampling process.Behind laboratory, horizontal positioned sampler also makes charging aperture on inner sleeve 4 upward, and slowly extracted by sampler inner sleeve 4, will see in each sample chamber 6 having a certain amount of silica flour, that is exactly the sample acquired by Different Silicon bisque.
After sampler inserts silica flour, the charging hole 2 that operator will can't see on outer tube 1, correctly judge that in order to help operator whether the charging hole 2 on outer tube 1 is relative with the charging aperture on inner sleeve 4, outer tube 1 and inner sleeve 4 are provided with centering graticule 3, when the centering graticule 3 of the two aligns, charging hole 2 on outer tube 1 is just relative with the charging aperture on inner sleeve 4, and sample chamber 6 is in open mode.
