Abstract
The utility model discloses a kind of neodymium iron boron hydrogen crushing furnace discharging sampler, it comprises the hollow tube running through hydrogen crushing furnace discharge nozzle, hollow tube is both ends open and top is provided with charging aperture, and one end of hollow tube is discharging opening, and the other end is provided with the push rod be placed in hollow tube.The utility model sampling is convenient and swift, can synchronized sampling during discharging, and need not shut down, the time decreased that powder exposes in atmosphere, sampling result is also more accurate.
Description
Technical field
The utility model relates to check sampling device, is specifically related to a kind of neodymium iron boron hydrogen crushing furnace discharging sampler.
Background technology
Utilize Nd in NdFeB alloy
2fe
14b principal phase and the different coarse crushing carrying out alloy of expansion coefficient after the attracting hydrogen of rich neodymium; i.e. quick-fried broken (the Hydrogen Decrepitation of so-called hydrogen; HD); it can make alloy casting piece broken along crystal boundary; so obtained powder major part is single crystal grain; coordinate airflow milling breaking method; the powder that particle mean size, size-grade distribution, powder morphology are excellent can be obtained; and use high purity inert gas to protect in the broken process of hydrogen; place magnetic and contact rear oxidation with air, this is all the necessary condition manufacturing high-performance neodymium-iron-boron magnet.
If but the dehydrogenation of hydrogen flour material is insufficient, there is free hydrogen in magnet, magnet can be caused to there is crackle, fragility increases, and bending strength reduces, and makes magnet not only hard but also crisp, adds the difficulty of subsequent mechanical processing.So, O is carried out to hydrogen flour material, the measurement of H element content just seems particularly important.Also be the Main Basis of improving technique.
Utility model content
For the defect that above-mentioned background technology exists, the utility model provides a kind of neodymium iron boron hydrogen crushing furnace discharging sampler.
For achieving the above object, the technical solution adopted in the utility model is: it comprises the hollow tube running through hydrogen crushing furnace discharge nozzle, hollow tube is both ends open and top is provided with charging aperture, and one end of hollow tube is discharging opening, and the other end is provided with the push rod be placed in hollow tube.
Further, one end of described push rod is provided with handle.
The utility model has following beneficial effect: the utility model sampling is convenient and swift, can synchronized sampling during discharging, and need not shut down, the time decreased that powder exposes in atmosphere, sampling result is also more accurate.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
As shown in Figure 1, the utility model comprises the hollow tube 2 running through hydrogen crushing furnace discharge nozzle 1, and hollow tube 2 is for both ends open and top is provided with charging aperture 4, and one end of hollow tube 2 is discharging opening 5, the other end is provided with the push rod 3 be placed in hollow tube 2, and one end of push rod 3 is provided with handle 6.
When needs feeding, pull-out push rod 3 in hollow tube 2, powder falls in hollow tube 2 from charging aperture 4, and inwardly pushing push rod 3, powder just drops out from discharging opening 5.When not needing feeding, push rod 3 pushes in hollow tube 2, and airtight whole charging aperture 4, can prevent air from entering and powder is oxidized.Convenient to operation like this, do not need to shut down, improve work efficiency.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
