Problems solved by technology

[0005] The above-mentioned experimental operations can all be completed in a glove box. At present, the conventional glove box has a relatively complicated structure or is expensive, and often has a double-layer structure. Generally, it is impossible to handle toxic and harmful gases. For simple operations or only inert As far as the local purification of gas protection is concerned in non-oxidation-reduction environments, it causes a huge excess of technology and waste of resources, and the price of tens of thousands to hundreds of thousands of yuan also greatly restricts its popularization and application.

Embodiment 1

[0034] A simple glove box, such as figure 1 and 2 As shown, it includes a fully transparent box body 1, a glove port 12 for operation, an inert gas source 4 connected to the box body 1 through an intake valve 7, a vacuum pump 5 connected to the box body 1 through an air extraction valve 8, and installed in the The operation door 2 on the left and right sides of the box body 1, the right side of the box body 1 is equipped with at least 4 air inlet nozzles 3 connected to the inert gas source 4, and the box body 1 is connected to the harmful gas through the filter valve 9. Gas filter 6; the edge of the contact surface between the above-mentioned operation door 2 and the box body 1 is provided with a magnetic material and a sealing ring, and the operation door 2 and the box body 1 are locked by a mechanical lock, and the gap between the operation door 2 and the box body 1 Suction by the magnetic material.

Embodiment 2

[0038] like image 3 As shown in (a) and (b), there are four air inlet nozzles 3, which are evenly distributed on the four corners of the right side of the box body 1, and the air inlet nozzles 3 run through the right side of the box body 1 , and all the intake nozzles 3 deflect 45° counterclockwise along the same circle where all the penetration points are located.

[0039] The design of the air intake nozzle 3 of the present invention abandons the traditional direct blowing design of a single air inlet, and the four air intake nozzles 3 cooperate with each other to form a vortex-shaped airflow inside the box body 1 and stir the inside of the box body All gases make the effect of directly using inert gas to replace the air in the box in manual mode and toxic and harmful gas mode better.

Embodiment 3

[0041] The magnetic material is a magnetic bar, and the magnetic bar is installed on the door edge of the operation door 2 and the position corresponding to the door edge on the box body 1, and the magnetic bar magnet between the operation door 2 and the box body 1 The suction force is 0.2MPa.

[0042]The operation door 2 adopts a double-seal structure, which not only has a mechanical lock, but also has a magnetic lock. When the mechanical lock is opened, the pressure in the box 1 can be kept within a certain pressure range, as long as the pressure in the box 1 is greater than the magnetic bar. The magnetic attraction force of the magnetic rod, the operation door 2 will be forced to open to release the pressure, and when the pressure in the casing 1 was less than the magnetic attraction force of the magnetic rod, the operation door 2 will be automatically closed under the magnetic force.

Abstract

The invention discloses a simple glove box and an using method thereof, wherein the glove box is composed of a box body, an operating door with a magnetic attraction lock and a plurality of air inlets, the air inlets are spirally arranged to blow out swirl airflow, while the operating door with the magnetic attraction lock is only used for gas intake, the gas is automatically discharged for pressure reduction when reaching a certain pressure; the simple glove box has the advantages of transparent structure, economy and durability, easy operation, less occupied area and wide application, besides it can be applied to inert gas operating environment and experiment researches of toxic and harmful gases.

Description

technical field [0001] The invention is applied to the operations that need to be carried out under inert gas atmosphere in laboratories and factories, and can be used for the treatment of a small amount of highly toxic and harmful gases produced in experiments and scientific research. Specifically, it is a simple glove box that is transparent, table-top, easy to operate and maintain, and has inert gas atmosphere protection gas and toxic and harmful experimental gas replacement treatment, and its use method. Background technique [0002] Modern laboratories and processing centers often need to use high-purity gases and high-purity materials for more complex modern fine processing and production, such as some large-scale analytical instruments (inductively coupled plasma mass spectrometry, laser ablation technology, inductively coupled plasma emission spectroscopy, etc. ) can achieve ultra-low content (less than 10-9μg / g) element content analysis, and some multi-receiver mass...
