Description

Simple glove box

Technical field:

The invention belongs to chemical industry equipment field, relate to a kind of Simple glove box that need to operate various materials under inert gas or anhydrous dustfree environment.

Background technology:

In chemical industry, electronics, medicine and other fields, often can run into the situation that need to operate under particular surroundings, for carry out anaerobic waterless operation under inert gas shielding, prior art is carried out in glove box.But now widely used glove box complex structure is huge, cost and maintenance are all very expensive, often be only applicable to specialized production, and for some middle-size and small-size users that often use or discontinuity are not used, and the user of teaching and laboratory use, just inapplicable, someone provides Simple glove box for this reason, useful flexible material is made the glove box of casing, " Simple glove box " providing as ZL200720063134.3, feature is " to make casing with overlay, do base with plank, by the two bonding one-tenth one confined space ", the shortcoming of being somebody's turn to do " Simple glove box " is in the time that casing is vacuumized, easily casing is shriveled, for this reason, need to be supported with bracing frame, and casing and base are bonded together, use very inconvenient.

Summary of the invention:

The object of the invention is to provide a kind of Simple glove box of new construction, can effectively overcome the shortcoming that existing equipment exists.

The present invention realizes like this, as shown in Figure 1, it includes casing 5, base plate 8 and gloves 4, it is characterized in that casing 5 use hard transparent materials making, there is no the regular hexahedron of bottom surface, on the tank wall in casing 5 fronts, be shaped with two circular tube shapeds, the gloves interface 3 of attaching gloves 4, be shaped with upper vent hole 2 in the back upper place of the left side wall of casing 5, on the pipeline being connected with upper vent hole 2, two-way valve 1 is installed, front lower place at the right side wall of casing 5 is shaped with lower passage 7, on the pipeline being connected with lower passage 7, three-way valve 6 is installed, upper vent hole 2 is opened on the diagonal that approaches casing 5 with lower passage 7, circular arc is all made in edges and corners in casing 5, on the wall thickness face of the bottom of 5 four sidewalls of casing, be all shaped with groove 9, in groove 9, sealing strip is housed, the base plate 8 being connected with casing 5 bottoms is square planar plate, on base plate 8 upper surfaces, be shaped with identical with the shape on 5 four bases of casing, can embed the groove 10 of cooperation.

Advantage of the present invention and good effect have: be 1. all made up of hard transparent material, transparency is high, need to lighting device be set at box house.2. fillet is all made in edges and corners, makes gas flow smooth and easy, does not stay dead angle.3. be shaped with respectively groove 9 and groove 10 in the bottom of box body wall with above base plate, can adopt as required sealing strip or water-stop, not only easy but also reliable.4. two passages are set, an inflation, an exhaust, does not need to vacuumize.5. small volume, weight is lighter, can arbitrarily move, in laboratory, workshop, factory building and indoor and outdoor can use.6. be convenient to clean, not fragile, cheap.Therefore the present invention is very suitable for teaching, research and is interrupted the user who uses.

The specific embodiment:

Example 1, to lanthanum, magnesium, nickel micro mist break seal, weigh, mix, charging, discharging and hydroprocessing

1. first carry out oxygen free operation

1. calculate the inert gas inflation required time of exhaust

The residual oxygen dividing potential drop p limiting _y=100 handkerchiefs, volume V=60 liter of casing 5, gas flow q=30 liter/min, by following formula

p = \frac{1}{5} \times 10^{5} \times {(\frac{1}{2})}^{\frac{30 t}{60}} < p_{y} = 100

Handkerchief

Can calculate the required time t > of inflation exhaust 15.3 minutes, get t=16 minute.

2. by two valves 1 up and down of casing 5, 6 open, will be respectively with three vacuum-packed lanthanoid metals of sack, magnesium, nickel micro mist and ethanol, spoon, balance, ball grinder, the utensils such as spanner are placed on above base plate 8, again casing 5 buttons are placed on above base plate 8, the bottom of four sidewalls embeds in groove 10, to the interior water filling sealing of groove 10, the inert gas argon gas that will be filled with due to this example is heavier than air, therefore argon gas can be filled with from lower passage 7, from upper vent hole 2 exhausts, argon gas by flowmeter with a little more than atmospheric steady pressure, be filled with in casing 5 with the pressure of 0.15 MPa and the flow of 30 liters/min, inflationtime is 16 minutes, then successively close lower passage and upper vent hole.

3. operating personnel operate in case by gloves 4: object will be prepared 50 grams of hydrogen bearing alloy LaNi ₅-31%Mg, cut off the packaging bags such as lanthanoid metal powder with scissors, weigh respectively 11.1 grams of lanthanum powder, 23.4 grams of nickel powders and 15.5 grams of magnesium powder, all pour in ball grinder, after adding again a small amount of ethanol, ball grinder is tamping, remaining lanthanum, magnesium, nickel micro mist are sealed respectively to preservation.

4. casing 5 is taken off from base plate 8, the ball grinder that mixed metal powder is housed is arranged on and on ball mill, carries out ball milling.

2. under hydrogen environment, operate

1. calculate the hydrogen inflation required time of exhaust

The residual air dividing potential drop p limiting _k=1000 handkerchiefs, volume V=60 liter of casing 5, gas flow q=30 liter/min, by following formula

p = 10^{5} \times {(\frac{1}{2})}^{\frac{30 t}{60}} < p_{k} = 1000

Handkerchief

Can calculate the required time t > 13.3 of inflation exhaust, get t=14 minute.

2. by two valves 1 up and down of casing 5, 6 open, by ball grinder, the utensils such as spanner are all placed on above base plate 8, again by casing 5 spiral-locks in the groove 10 on base plate 8, to the interior injected water sealing of groove 10, due to the hydrogen lta that will be filled with, therefore hydrogen is filled with from upper vent hole 2, from lower passage 7 exhausts, hydrogen by flowmeter with a little more than atmospheric steady pressure, be filled with in casing 5 with the pressure of 0.15 MPa and the flow of 30 liters/min, inflate after 14 minutes, successively close lower passage and upper vent hole, then operating personnel operate by gloves 4, in case, dismantle and be loaded with 50 grams of hydrogen storing alloy powder LaNi with spanner ₅the ball grinder of-31%Mg, is filled with in tank hydrogen, then ball grinder is tamping, and then casing 5 is taken off from base plate 8, will be filled with ball grinder ball milling on ball mill of hydrogen and hydrogen storing alloy powder, makes hydrogen storing alloy powder inhale hydrogen hydrogenation.

Example 2, to aluminum refining agent chlorination zinc powder break seal, weighing and encapsulation operation

1. calculate the dry air inflation required time of exhaust

The residual water vapor dividing potential drop p limiting _s=100 handkerchiefs, volume V=60 liter of casing 5, gas flow q=30 liter/min, by following formula

p = 10^{3} \times {(\frac{1}{2})}^{\frac{30 t}{60}} < p_{s} = 100

Handkerchief

Calculate the required time t > 6.3 of inflation exhaust, get t=7 minute.

2. by two valves 1 up and down of casing 5, 6 open, mounting O-shaped sealing ring in casing lower edge groove 9, the chlorination zinc powder of packing through processed will be used, spoon, balance, the utensils such as polybag are placed on above base plate 8, again casing 5 buttons are placed on above base plate 8, the bottom of four sidewalls embeds in groove 10, because the dry air that will be filled with is lighter than the interior undried air of casing 5, dry air is filled with from upper vent hole 2, discharge from lower passage 7, dry air by flowmeter with a little more than atmospheric steady pressure, be filled with in casing 5 with the pressure of 0.15 MPa and the flow of 30 liters/min, inflationtime 7 minutes, then successively close lower passage and upper vent hole, in casing, cut off dehydration chlorination Zincum powder packing bag by gloves 4, want 2% weighing zinc chloride of the weight of the aluminium alloy of melting according to preparation, then be encapsulated in polybag, to remain dehydration chlorination zinc powder also packaged, then casing 5 is taken off from base plate 8, instrument and material are packed up.
