Description

Vacuum glove box

Technical field

The utility model vacuum glove box relates to is that a kind of various types of materials and some midget plants are placed on charges into the casing that uses and operate in the environment of unreactable gas after vacuumizing.

Background technology

Existing glove box adopts the wind circulation purification style to come the purifying box internal milieu, price height, palpus 24 continuous throughout the twenty-four hour24s, later stage use, maintenance cost height.In view of many experiments being arranged in domestic many universities and colleges, R﹠D institution and the industrial and mining enterprises and producing and must finish in vacuum environment, because the glove box price height of circulating system, factors such as later stage use, maintenance cost height can not be extensive use of.Be badly in need of at present providing a kind of simplicity of design, price is low, the later stage expense is also low vacuum glove box, to solve user's practical problems.

Summary of the invention

The utility model provides a kind of vacuum glove box at above-mentioned weak point, this vacuum glove box adopts whole box body is vacuumized, charge into high-purity inert gas then, under atmosphere of inert gases, use and operate, and vacuum glove box has a prime chamber, and the use of whole box body is played a significantly greater role.When object will pass in and out casing, as long as independent extraction prime chamber, must the extraction whole box body, reduced work-hours, reduced use cost.

Vacuum glove box takes following scheme to realize: the vacuum glove box structure is made of main box, prime chamber.Main box comprises casing, form, gloves interface, vacuum indicator, vaccum electric apparatus socket, vacuum valve.The prime chamber comprises chamber body, glove box door, vacuum indicator, vacuum valve, plate.Device has the vacuum seal pad between main box and the prime chamber, assembles by attaching parts.The prime chamber can be contained in arbitrary of the main box left and right sides according to customer requirements.Before and after the main box casing form and gloves interface can be arranged all, form is divided into preceding form, rear view window, can many people use simultaneously; Be furnished with several vacuum valves on the main box, water nozzle all is housed inside and outside the valve, can use any one valve to provide cooling water expansion tank to inflation in the casing or to other equipment in the casing.Can vacuumize it separately by the vacuum valve on the prime chamber.Glove box door comprises inside door, external door, is contained in two ends, prime chamber respectively.Glove box door is being made up of handle, push rod, depression bar, balance block, and it is convenient that inside and outside door is opened, and twitches active plugboard the interior article of casing are picked and placeed freely.

The advantage of vacuum glove box:

1, simple in structure, good airproof performance.Be the angle, garden around the casing, be convenient to cleaning.

2, casing adopts corrosion-resistant stainless steel, and is applied widely, and preceding form (adopting organism glass or case hardened glass) area is big, has a wide sphere of vision.

3, low price, easy to use, the later stage expense is low.

4, guaranteeing under the main box environment unmodified prerequisite energy continuous feeding and discharging, continuous handling, test.

The specific embodiment

With reference to accompanying

drawing

1,2,3,4, the vacuum glove box structure is made of main box, prime chamber.Main box comprises casing 1, form, gloves interface 9, vacuum indicator 7, vaccum electric apparatus socket 8, vacuum valve 6.Be provided with form 2 before the casing 1, after be provided with form 12, all gloves interface 9 can be arranged before and after the main box, the gloves interface is outside equipped with gloves flap 3, and a vacuum indicator 7, several vacuum valves 6 are housed on the main box 1.Several vaccum electric apparatus sockets 8 are housed on the main box 1.Water nozzle all is housed inside and outside the vacuum valve 6, can or provides water inflation in the casing.The prime chamber comprises chamber body 4, glove box door, vacuum indicator 13, vacuum valve 14, plate.Glove box door comprises inside door 11, external door 15, and glove box inside door 11 is contained between chamber, prime chamber body 4 and the main box 1, and the outer door gear of glove box is at the front end of chamber, prime chamber body 4, and plate 17 devices are in body 4 bottoms, chamber, prime chamber, and the bottom has guide track.Glove box door 15 devices have door knob 5, door knob 5 is made up of handle 5-1, push rod 5-2, depression bar 5-3, balance block 5-4, handle 5-1 links to each other with push rod 5-2, depression bar 5-3 is sleeved on push rod 5-2 and goes up and be fixed on end, prime chamber, chamber door is fixed on the push rod 5-2 by set screw, and the inside and outside door of glove box chamber door doorknob structure is identical.Vacuum indicator 13 devices are on body 4 tops, chamber, prime chamber, and vacuum valve 14 devices are in the side of chamber, prime chamber body 4.Device has vacuum seal pad 18 between main box and the prime chamber, assembles by tie bolt 10.Gloves flap 3 is communicated with vacuum valve 14 by vacuum rubber pipe 16, is in vacuum state to keep gloves interface 9.

Principle of work: during vacuum glove box work, promote chamber door and open glove box door to 5, required article are put into glove box, shut the glove box external door, adopt vacuum rubber pipe 16 to connect all gloves interfaces of glove box (see figure 3), make it to link to each other with main box by vacuum valve, utilize the vacuum valve 6 on the casing to vacuumize, degree of vacuum in the whole box body is reached-0.1MP (seeing vacuum indicator 7), then can be by any one vacuum valve 6 filling with inert gas in casing on the casing, vacuum indicator 7 is got back to≤0MP, closed the valve that gloves link to each other with casing, open gloves flap 3 and just can operate.The operational circumstances that can be clear that in the casing by front and back form 2,12.Put or take out article into casing as needing this moment, as long as the prime interior door is shut, opens prime exterior door 15.As put into or take out article, and then shut external door 15, the prime chamber is vacuumized and filling with inert gas, open inside door 11 again.So both shorten the time that vacuumizes, also reduced the consumption of unreactable gas.Two vaccum electric apparatus sockets 8 have been installed on the main box, can have been connected suitable equipment in the casing.

Use connection diagram with reference to Fig. 3 vacuum glove box, when glove box vacuumized, the method shown at first will going up by figure linked to each other gloves interface 9 with any valve on the casing, and opens valve.

With reference to Fig. 4 vacuum glove box doorknob structure scheme drawing, when handle 5-1 upwards pushed away, handle drove push rod 5-2, and door is opened.Simple in structure, it is convenient to open.There have balance block 5-4 to make that the casing inside door operates on the depression bar 5-3 to be more free and relaxed.
