Description
Technical field
The present invention relates to a kind of vacuum environment control box, particularly a kind of vacuum environment control box that is used for the nano-fluid preparation.
Background technology
At present, along with the development of nanosecond science and technology, the range of application of nano material also more and more widely.Especially after the notion of nano-fluid proposes, make its research in heat transfer, mass transfer field rise gradually, yet the prerequisite of studying for the nano-fluid heat and mass transfer enhancement is to prepare the stabilized nano fluid that is uniformly dispersed.In the preparation method of nano-fluid, dispersion method be a kind ofly be easy to most to realize, also method the most commonly used, the basic procedure of its preparation is that nano-powder is positioned among the base fluids such as water or ethylene glycol, makes it to be uniformly dispersed in base fluid by external force effects such as magnetic agitation or supersonic oscillations then.Because the nano material size is minimum, specific area is very big, very easily oxidation or sclerosis when being exposed in the air, thereby take out from vacuum packaging bag in nano material and will avoid contacting with air when putting in the base fluid, and the object of the invention makes nano material avoid contacting with air exactly and guarantees that nano material puts into base fluid under the stay-in-grade situation.
Against vacuum environmental operations case, it as the patent No. 02219258.1 vacuum glove box, because attaching parts are more, make the body structure complexity, thereby the probability and the square box that have increased vacuum leak are all uneconomical for the utilization of the manufactured materials and the useful space, and the form of front and back position is in operation and observe and be an impediment to the vision coverage when synchronous.The present invention has effectively solved the problems referred to above, makes to prevent to become simple aspect nano-powder oxidation or the sclerosis when the preparation nano-fluid.
Summary of the invention
The present invention will solve in the nano-fluid preparation to influence the oxidation of nano-fluid performance, the technical problem of sclerosis, and a kind of vacuum environment control box for preparing nano fluid is provided, this body structure is simple, the useful space is big, good airproof performance, operation and observation are comfortable.
Technical scheme of the present invention is: a kind of vacuum environment control box for preparing nano fluid, comprise circular groove shape casing, safety glass cover plate, seal washer, rubber gloves, vacuum meter, gloves compress steel loop, gathering hole seal cover board, vacuum valve, be characterized in: circular groove shape casing top is provided with open slot, seal washer is bonded in the casing upper opening groove, the safety glass cover plate is positioned on the casing upper opening groove, and compress seal washer, the casing middle part has vacuum meter interface, bleeding point, air inlet, and connects pressure vacuum gauge, vacuum valve respectively; Have two gathering holes on the casing, there is one section projection that is used to place rubber gloves gathering hole and casing junction, the projection outer end is welded with flange, rubber gloves is close on the flange, seal washer is covered on rubber gloves and the flange, and is close on the seal washer with steel loop, by six hold-down bolts steel loop is pressed on the flange, one deck seal washer is pasted in the steel loop outside, and two gathering hole seal cover boards compress by four hold-down bolts respectively and are sealed on the gathering hole.
Angle is 100 degree between two gathering holes, and gathering hole and form are and are arranged vertically; The length of projection is 5-7cm.
Beneficial effect of the present invention is: body structure is simple, the valid function space big, good sealing effect, operational observations are comfortable, can play great role to the superperformance of prepared nano-fluid.

Fig. 3 vacuum environment control box for preparing nano fluid gathering hole of the present invention profilograph.
The specific embodiment
The present invention is further illustrated below in conjunction with accompanying drawing and embodiment.
As Fig. 1 vacuum environment control box for preparing nano fluid overall structure figure: this control box is mainly by circular groove shape casing 2, safety glass cover plate 4, seal washer 3, bleeding point 8, air inlet 9, pressure vacuum gauge interface 6, pressure vacuum gauge 5, vacuum valve 7,10, gathering hole 1,11, rubber gloves 14, steel loop 16, gathering hole seal cover board 20, hold-down bolt 17 combine.
Circular groove shape casing 2 upper openings, seal washer 3 is bonded in the casing 2 upper opening grooves, and safety glass cover plate 4 is positioned on the casing upper opening, compresses sealing gasket and encloses sealing process, simultaneously also be used to observe operational circumstances in the casing, as shown in Figure 2 as form.Simultaneously have vacuum meter interface 6, bleeding point 8, air inlet 9 at casing 2 middle parts, the outside connects pressure vacuum gauge 5, vacuum valve 7,10 respectively, as shown in Figure 1.Pressure vacuum gauge 5 be used to show take out, the pressure during air inlet in the casing, the keying with decision extraction valve 7, intake valve 10 guarantees the vacuum in the casing 2.
Have two gathering holes 1,11 on the casing 2, the gathering hole height is decided according to casing and the operating instrument height of putting into casing, general middle and lower part at casing, instrument in the operation casing that can Energy and comfort and take nano material, the gathering hole diameter is according to the rubber gloves diameter and can make things convenient for hand insertion control box to decide, angle is 100 degree between two gathering holes, is two work angles that hand is comparatively suitable.
Gathering hole structure such as accompanying drawing 3: there is one section projection 12 gathering hole 1,11 and casing 2 junctions, and length is advisable with 5-7cm, are used for rubber gloves 14 is positioned over wherein, to prevent that gloves take up room when vacuumizing in casing, to collide instrument or nano material.Projection 12 outer end welded flanges 13, rubber gloves 14 is close on the flange 13, seal washer 15 is covered on rubber gloves 14 and the flange 13, be close on the seal washer 15 with steel loop 16, by six hold-down bolts 17 steel loop 16 is pressed on the flange 13 then, casing 2 internal and external environments are just separated by rubber gloves 14 like this.One deck seal washer 18 is pasted in steel loop 16 outsides, and gathering hole seal cover board 20 compresses by four hold-down bolts 19 and is sealed on the gathering hole, and seal cover board 20 can take down by disassembling hold-down bolt 19.When casing is vacuumized, the " locked in " operation velar plate, can make and bear high vacuum in the casing and do not damage rubber gloves, after injecting desired gas such as a certain amount of nitrogen or inert gas, lay down hold-down bolt, take down the gathering hole cover plate, can carry out operation in the casing by the rubber gloves in the gathering hole.The situation of another gathering hole and aforesaid operations mouth are identical.
Use step during the preparation nano-fluid is: open glass cover-plate, rubber gloves is positioned over the gathering hole raised section, balance, spoon, vacuum-packed nano material, required instrument, the materials such as container that fill base fluid are put into casing, cover glass cover-plate, " locked in " operation velar plate, close intake valve.Opening extraction valve vacuumizes casing with vavuum pump, observe vacuum meter, close extraction valve when meeting the requirements of vacuum, in casing, fill desired gas such as nitrogen, inert gas by intake valve then, observe and close intake valve when the vacuum tabular value reaches near an atmospheric pressure, make in the casing to make the top cover plate be impaction state, to improve sealing effectiveness for a small amount of negative pressure.Lay down the hold-down bolt on the gathering hole, take down the gathering hole cover plate, the nano-powder in the casing is carried out the weighing operation, the nano-powder of measuring is put into the container that fills base fluid by rubber gloves, stirring is sunk in the base fluid nano-powder fully, sealing nano-powder packing sack.Operation is finished, and opens intake valve and makes the pressure in the casing reach an atmospheric pressure, opens glass cover-plate, takes out instrument and material in the casing.
