Problems solved by technology

At present, some manufacturers in the industry frequently restore and clean products. In addition to the problems of sealing and regeneration of purification materials, there are unreasonable structural design of purification columns, unscientific design of height-to-diameter ratio, and unscientific flow control of reducing gas. Factors such as incomplete restoration and regeneration each time

Embodiment 1

[0039] Example 1, such as Figure 1-3As shown, a glove box with a purification system includes a main box body 1, a transition cabin 2, a glove operating port 3, a purification system 4, and a power system 6. The main box body 1 and the transition cabin 2 are respectively provided with valves connected to Air extraction and inflation interface; the purification system 4 includes a sealing cover 46 and a purification cylinder 47, and the sealing cover 46 and the purification cylinder 47 are connected by bolts 42; the main air passage 41 and the heater 45 are fixed in the purification cylinder 47; the purification cylinder 47 The inner wall is provided with a spiral air passage 43, and the purification cylinder 47 is filled with purification materials.

Embodiment 2

[0040] Embodiment 2, the gap between the spiral air passage 43 in the embodiment 1 and the bottom of the purification cylinder 47 is 30mm, and the spiral air passage rise angle is 15°.

Embodiment 3

[0041] Embodiment 3, a method of using a glove box with a purification system:

[0042] The first step: the purification system 4 is restored;

[0043] Firstly, connect the purified gas source 5, heat the purified material, and the heating time is 100 minutes; feed the reducing gas for 2 minutes, and the gas flow rate is 10 L / min; keep the pressure for 15 minutes and then vacuumize for 15 minutes; then pass the gas flow automatic controller in two stages Reducing gas, the total time is 120min; the first stage is 30min, the gas flow rate is 10L / min; the second stage is 90min, the gas flow rate is 10L / min; the above procedure is repeated 4 times;

[0044] Step 2: Put in materials, experimental instruments or tools;

[0045] Open the outer door of the transition cabin 2, put the materials to be placed on the material platform in the transition cabin 2, then open the inner hatch of the main box 1, add the materials to be placed in the main box 1; close the main box 1, Transition...

Abstract

The invention relates to a glove box with a purification system and usage thereof. The glove box structurally comprises a main box body (1), a transition chamber (2), glove operation openings (3), the purification system (4) and a power system (6); the main box body (1) and the transition chamber (2) are respectively provided with a valve, and are connected with exhaust and charge ports; the glove box is characterized in that the purification system (4) comprises a sealing cover (46) and a purification cartridge (47), and the sealing cover (46) is connected with the purification cartridge (47) through bolts (42); a main air passage (41) and a heater (45) are fixedly arranged in the purification cartridge (47); a helical air passage (43) is arranged on the inner wall of the purification cartridge (47), and purification material fills the purification cartridge (47). The purification and regeneration effect of the glove box is good, and the utilization rate of the purification material is high.

Description

technical field [0001] The invention belongs to the field of glove boxes, in particular to a glove box with a purification system. Background technique [0002] At present, in the field of drying, heating, decompression and freezing are often used to dry solids. The most common methods are ovens, vacuum ovens, etc., and vacuum ovens have better drying effects. The application process of the vacuum oven is to place the dry material in a closed drying room, and heat the material to be dried while vacuuming with a vacuum system, so that the moisture inside the material diffuses to the surface through the pressure difference or concentration difference, and the water molecules in the material The surface obtains sufficient kinetic energy, and after overcoming the mutual attraction between molecules, it escapes to the low-pressure space of the vacuum chamber and is thus sucked away by the vacuum system. During the vacuum drying process, the pressure in the drying chamber is alwa...
