Description

The simple type glove box

Technical field:

The utility model belongs to the chemical industry equipment field, relates to a kind of simple type glove box that need under inert gas or anhydrous dustfree environment, operate various materials.

Background technology:

In chemical industry, electronics, medicine and other fields, run into situation about need under particular surroundings, operate through regular meeting, under inert gas shielding, carrying out the anaerobic waterless operation, prior art is carried out in glove box.But present widely used glove box complex structure is huge, and cost is all very expensive with maintenance, often only is applicable to specialized production; And for the middle-size and small-size user that some often do not use or discontinuity is used, and the user of teaching and laboratory use, just inapplicable; The someone provides the simple type glove box for this reason, and useful flexible material is made the glove box of casing, " the simple type glove box " that provides like ZL200720063134.3; Characteristic is " process casing with overlay, do base with plank, with the two bonding one-tenth one confined space "; The shortcoming of being somebody's turn to do " simple type glove box " is when casing is vacuumized, and easily casing is shriveled, for this reason; Need support with bracing frame, and casing and base are bonded together, use very inconvenient.

Summary of the invention:

The utility model purpose provides a kind of simple type glove box of new construction, can overcome the shortcoming that existing equipment exists effectively.

The utility model is achieved in that as shown in Figure 1, and it includes casing 5, base plate 8 and gloves 4; It is characterized in that casing 5 usefulness hard transparent materials make, do not have the regular hexahedron of bottom surface; On the positive tank wall of casing 5, be shaped on gloves interfaces 3 two pipe shapes, attaching gloves 4, be shaped on upper vent hole 2, and on the pipeline that upper vent hole 2 is connected bilateral valve 1 is installed in the back upper place of the left side wall of casing 5; Be shaped on passage 7 down in the front lower place of the right side wall of casing 5; With on the pipeline that following passage 7 is connected three-way valve 6 is installed, upper vent hole 2 is opened on the diagonal near casing 5 with following passage 7, circular arc is all processed in casing 5 interior edges and corners; All be shaped on groove 9 on the wall thickness face of the bottom of 5 four sidewalls of casing; In the groove 9 sealing strip is housed, the base plate that is connected with casing 5 bottoms 8 is the square planar plate, on base plate 8 upper surfaces, is shaped on the groove 10 that shape with 5 four bases of casing is identical, can embed cooperation.

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

The specific embodiment:

Example 1, to lanthanum, magnesium, nickel micro mist break seal, weighing, mixing, charging, discharging and hydroprocessing

1. at first carry out oxygen free operation

1. calculate the inert gas inflation required time of exhaust

The residual oxygen dividing potential drop p that limits _y=100 handkerchiefs, the volume V of casing 5=60 liter, gas flow q=30 liter/minute, then by following formula

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

2. two valves 1,6 up and down of casing 5 are all opened, will be placed on above the base plate 8 with utensils such as three the vacuum-packed lanthanoid metals of sack, magnesium, nickel micro mist and ethanol, spoon, balance, ball grinder, spanners respectively; Again casing 5 buttons are placed on above the base plate 8; The bottom of four sidewalls embeds in the groove 10, and water filling sealing in groove 10 is because the inert gas argon gas that this example will charge into is heavier than air; So can argon gas be charged into from following passage 7; From upper vent hole 2 exhausts, argon gas, charges in casing 5 with the pressure of 0.15 MPa and 30 liters/minute flow with a little more than atmospheric steady pressure through flowmeter; Inflationtime is 16 minutes, successively closes down passage and upper vent hole then.

3. operating personnel operate in case through gloves 4: purpose will prepare 50 gram hydrogen bearing alloy LaNi ₅-31%Mg; Cut off packaging bags such as lanthanoid metal powder with scissors, weighing 11.1 gram lanthanum powder, 23.4 gram nickel powders and 15.5 gram magnesium powder are all poured in the ball grinder respectively; Add after the small amount of ethanol ball milling potting is tight again, remaining lanthanum, magnesium, nickel micro mist are sealed preservation respectively.

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

2. under hydrogen environment, operate

1. calculate the hydrogen inflation required time of exhaust

The residual air dividing potential drop p that limits _k=1000 handkerchiefs, the volume V of casing 5=60 liter, gas flow q=30 liter/minute, then by following formula

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

2. two valves 1,6 up and down of casing 5 are all opened, utensils such as ball grinder, spanner all are placed on above the base plate 8; With in the groove 10 of casing 5 spiral-locks on base plate 8, in groove 10, inject water-stop again, because the hydrogen lta that will charge into; So hydrogen is charged into from upper vent hole 2, from passage 7 exhausts down, hydrogen through flowmeter with a little more than atmospheric steady pressure; Charge in casing 5 with the pressure of 0.15 MPa and 30 liters/minute flow, inflate after 14 minutes, successively close down passage and upper vent hole; Operating personnel operate through gloves 4 then, promptly in case, dismantle with spanner and are loaded with 50 gram hydrogen storing alloy powder LaNi ₅The ball grinder of-31%Mg charges in the jar hydrogen, and is again that the ball milling potting is tight, takes off casing 5 from base plate 8 then, with the ball grinder that is filled with hydrogen and hydrogen storing alloy powder ball milling on ball mill, 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 that limits _s=100 handkerchiefs, the volume V of casing 5=60 liter, gas flow q=30 liter/minute, then by following formula

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

2. two valves 1,6 up and down of casing 5 are opened, the O RunddichtringO is installed in casing lower edge groove 9; To be placed on above the base plate 8 with utensils such as the chlorination zinc powder of packing through processed, spoon, balance, polybags, and casing 5 buttons will be placed on above the base plate 8 again, the bottom of four sidewalls embeds in the groove 10; Because the dry air that will charge into is lighter than undried air in the casing 5, dry air is charged into from upper vent hole 2, from passage 7 discharges down; Dry air with a little more than atmospheric steady pressure, charges into inflationtime 7 minutes through flowmeter in casing 5 with the pressure of 0.15 MPa and 30 liters/minute flow; Successively close down passage and upper vent hole then, in casing, cut off the packaging bag of dehydration chlorination zinc powder, want the 2% weighing zinc chloride of weight of the aluminium alloy of melting according to preparation through gloves 4; Be encapsulated in the polybag then; It is also packaged to remain dehydration chlorination zinc powder, takes off casing 5 from base plate 8 then, packs up instrument and material.
