Abstract
The utility model relates to a device for preparing metal nanometer metal alloy ultramicron catalyst with two metals whose melting points have a large difference from each other. A vacuum chamber is provided with an upper Mo boat crucible and a lower Mo boat crucible, one side of the vacuum chamber is provided with an air duct, and the other side of the vacuum chamber is provided with a vibrating feeder which can respectively feed in the two crucibles simultaneously. Two power supplies are adopted to separately control the heating of the two Mo boat crucibles. The upper part of the inside of the vacuum chamber is provided with a cold trap, and prepared nanometer Cu Zn alloy is deposited on the cold trap. The utility model has the advantages of novel and simple structure, convenient use and easy control.
Description
The utility model relates to the device that a kind of preparation fusing point of being made up of parts such as vacuum chamber, cold-trap, Mo boat crucible and vibrating feeder (conveyer)s differs bigger two kinds of metal nano alloy ultro-micro partical catalyst.
At present, the research of nano material and preparation still are in China to be explored and advanced development, especially also do not forming unified pattern and specification aspect the apparatus of preparation nano material, apparatus for the alloy nano catalyst for preparing two kinds of materials with high melting point (as Cu or Zn) is all the more so, existing apparatus is pieced together according to principle basically, so its complex structure and disunity, process conditions are wayward, experimentation instability, result are also not ideal enough.
Goal of the invention of the present utility model is to overcome shortcoming and the difficulty that exists in the prior art, seeks that design and manufacture is a kind of to be used to prepare the device that fusing point differs Nanoalloy (as Cu and the Zn) ultrafine particle catalyst more than 500 ℃.
In order to realize the foregoing invention purpose, the utility model adopts stainless steel material through being processed into round boxlike vacuum chamber housing, the space forms vacuum chamber in the housing, its bottom is shaped on the chassis, the vacuum chamber internal upper part is shaped on cold-trap, be shaped on last Mo boat crucible and following Mo boat crucible below the cold-trap at a distance of certain distance, two Mo boat crucibles respectively with two outer power supply electric connections of vacuum chamber, to guarantee the heating of two Mo boats of bio-occlusion crucible, be shaped on wireway two Mo boat crucible one sides, its gas outlet horizontal direction faces Mo boat crucible, intersect vertically with the atom that evaporates in the gas that guarantee to feed and the crucible, two Mo boat crucible opposite sides are shaped on the vibrating feeder (conveyer) that contains two Feeding boxs, respectively vibration charging in two Mo boat crucibles.
It is simple that the utility model compared with prior art has a novel structure, uses easy to operately, is easy to advantages such as control.
Fig. 1 is the theory structure schematic diagram of the utility model.
The device of implementing corresponding preparation nanometer CuZn alloy ultro-micro partical catalyst of the present utility model, the interior space of the round cassette shell 1 that the employing stainless steel material is processed into forms can bear 10
-5The vacuum chamber 10 of the vacuum that τ is above, its bottom is shaped on chassis 9, vacuum chamber 10 internal upper parts are shaped on cold-trap 6, be shaped on last Mo boat crucible 5 and following Mo boat crucible 4 below it respectively at a distance of certain distance, and respectively with heating power supply 8 and 7 electric connections, be shaped on the wireway 2 that can feed argon gas two Mo boat one sides, its gas outlet horizontal direction faces crucible, when evaporation atom in the crucible rises, the gas that feeds with wireway 2 intersects vertically, so that cause the hot plasma arc, and two kinds of metals (Cu and Zn) atom that two Mo boat crucibles are evaporated mixes mutually and runs foul of each other, to form the CuZn alloy ultro-micro partical, two Mo boat opposite sides are shaped on the vibrating feeder (conveyer) 3 that contains two Feeding boxs 11, respectively vibration charging in two Mo boat crucibles.
During use, vacuum chamber 10 is evacuated to 10
-5The vacuum of τ, last Mo boat crucible 5 is used to adorn copper, and following Mo boat crucible 4 is used to adorn zinc, connects power supply 8 earlier, when making the copper heating evaporation treat the Cu fusing, connects power supply 7 again and makes the zinc heat fused.In heating simultaneously, connect wireway 2 and charge into argon gas, just can cause heat etc., form the CuZn alloy ultro-micro partical and be deposited on the cold-trap from the roman arc.
Claims (2)
1, a kind of nanometer CuZn alloy ultro-micro partical catalyst equipment device of forming by vacuum chamber, cold-trap, Mo boat and vibrating feeder (conveyer) etc., it is characterized in that the space forms vacuum chamber in the circle cassette shell, its bottom is shaped on the chassis, the vacuum chamber internal upper part is shaped on cold-trap, be shaped on upper and lower two Mo boat crucibles below the cold-trap at a distance of certain distance, and respectively with two power supply electric connections, two Mo boat crucible one sides are shaped on wireway, its gas outlet horizontal direction faces crucible, and two Mo boat crucible opposite sides are shaped on the vibrating feeder (conveyer) that contains two Feeding boxs.
2, nanometer CuZn alloy ultro-micro partical Preparation of Catalyst device according to claim 1, the vacuum that it is characterized in that vacuum chamber is 10
