Description

Pollution prevention device for transition cabin of glove box

Technical Field

The utility model relates to a glove box auxiliary device especially relates to an anti-pollution device of transition cabin for glove box.

Background

At present, the glove box is widely applied to the fields of physical chemistry, materials, lithium ion batteries, super capacitors, nuclear industry, biological medicine and the like. According to different experiments performed by users, various test materials are arranged in the box body, and most of the test materials are toxic substances, so that irritant toxic gas volatilized from the toxic substances is arranged in the box body.

The transition cabin of glove box is used for with external transmission article, and the transition cabin has interior outer door, and conventional glove box is put into transition cabin evacuation tonifying qi (mend the gas of low water low oxygen in the glove box, prevents the influence of external air to the low water low oxygen atmosphere in the box) with article from the outer door and puts into the glove box again the interior door. However, as the irritant and toxic gas in the box body is supplemented, when the outer door of the transition cabin is opened, the irritant and toxic gas can be diffused indoors and inhaled by operators, so that the health of the operators is seriously affected, and the environment is polluted.

SUMMERY OF THE UTILITY MODEL

The utility model provides an anti-pollution device of transition cabin for glove box has solved the glove box and has taken out the problem that has the article of noxious material, its technical scheme as follows:

the utility model provides an anti-pollution device of transition cabin for glove box, includes the transition cabin body, the both ends of the transition cabin body are provided with transition cabin inner door and transition cabin outer door respectively, the side of the transition cabin body is provided with vacuum pump valve and working gas valve, and upper portion is provided with the pressure sensor of control transition cabin body tonifying qi.

The transition cabin body is fixed on the peripheral frame through a glove box body steel plate, the transition cabin body area at the left end of the glove box body steel plate is an inner area of the glove box, and the transition cabin body area at the right end of the glove box body steel plate is an outer area of the glove box.

The transition cabin inner door and the transition cabin outer door are both provided with locking control devices, and only one door is limited to be in an opening state through the locking control devices.

And the vacuum pump valve is connected with a vacuum pump through an air pumping pipeline.

The working gas valve is connected with the gas supplementing device through a gas charging pipeline.

The air supply device is supplemented with inert gas or nitrogen.

The transition cabin anti-pollution device for the glove box realizes a non-toxic treatment mode of the transition cabin by setting a gas replacement function, is simple to operate, is safe and reliable, and is non-toxic in use.

the reference numbers in the figures:

1-a transition cabin inner door; 2-transition cabin outer door; 3-a pressure sensor; 4-steel plate of glove box body; 5-vacuum pump valve; 6-working gas valve.

Detailed Description

As shown in fig. 1, the pollution prevention device for the transition cabin for the glove box comprises a transition cabin body, wherein two ends of the transition cabin body are respectively provided with an inner door 1 and an outer door 2 of the transition cabin, and the transition cabin body can be communicated with the glove box by opening the inner door 1 of the transition cabin body; and opening the outer door 2 of the transition cabin to communicate the transition cabin with the outside.

The transition cabin body is fixed on the peripheral frame through a glove box steel plate 4, the glove box steel plate 4 is used for separation, the area A of the transition cabin body, which is located at the left end of the glove box steel plate 4, is an inner area of the glove box, and the area B of the transition cabin body, which is located at the right end of the glove box steel plate 4, is an outer area of the glove box.

The side of the transition cabin body is provided with a vacuum pump valve 5 and a working gas valve 6, and the transition cabin body is connected with a vacuum pump through the vacuum pump valve 5 and is connected with a gas supplementing device through the working gas valve 6.

The upper portion of the transition cabin body is provided with a pressure sensor 3, and the air supplement function of the transition cabin body is controlled by installing the pressure sensor 3, so that the transition cabin inner door can be opened after the air supplement makes the pressure inside the glove box balanced with the pressure inside the transition cabin, and the vacuum degree of the transition cabin body is controlled by the pressure sensor 3.

Taking out external operation flow of articles in the glove box through the transition cabin: opening the inner door 1 of the transition cabin, putting articles into the transition cabin, and closing the inner door 1 of the transition cabin; carry out the evacuation to the transfer chamber through the vacuum pump, through pressure sensor 3 control evacuation to set pressure, close the valve of connecting the vacuum pump, open the valve of connecting the working gas, mend the pressure of working gas through pressure sensor 3 control transfer chamber, the pressure of working gas is 0.4Mpa generally, glove box internal pressure is 1000pa, makes transfer chamber and glove box internal pressure balanced, closes the valve of connecting the working gas, opens the outer door of transfer chamber, takes out article.

Because the air supplementing link is supplemented with clean working air, the air in the transition cabin can not cause damage and environmental pollution to operators when the outer door of the transition cabin is opened.
