Abstract
Description
Technical Field
[0001] The invention relates to the technical field of glove box equipment, and in particular to an integrated device of a glove box purification column and a valve body pipeline. Background Art
[0002] The glove box is a laboratory equipment that fills a sealed box with high-purity inert gas and circulates to filter out the active substances in it. It is widely used in high-tech research fields and production processes such as medicine, biology, chemistry and chemical engineering, nuclear energy, and lithium batteries. The glove box can not only provide a water-free and oxygen-free experimental environment for various scientific research and production, but also provide safety protection for scientific researchers, such as medical biological bacteria and disease prevention, nuclear energy radiation and leakage prevention, and chemical and chemical protection against toxic gases, etc.
[0003] At present, the glove box mainly includes a box body, a purification system, and a circulation system. The working principle is that after the circulation system is turned on, the gas in the box is driven to continuously flow through the purification system. The purification system continuously removes the oxygen and water that are increased due to leakage from the box body or scientific research and production operations, so that the oxygen and water are controlled within a certain range to meet the requirements of users.
[0004] At present, the purification system of the glove box is composed of a purification column composed of a purification and dehydration unit and a purification and deoxygenation unit. Two KF40 interfaces are opened on the top of the purification column. Two high vacuum flapper valves are installed on the two interfaces respectively. The two high vacuum flapper valves are connected to the air inlet and the air outlet through bellows. The bellows of the air inlet is also connected to the working gas pipeline, and the two KF40 interfaces are also connected to the regeneration pipeline. This makes the internal pipeline of the glove box very complicated and prone to leakage. The glove box also becomes large and bulky, causing a lot of inconvenience in transportation, use and maintenance.
[0005] Therefore, it is necessary to provide a new integrated device of a purification system to solve the above technical problems. Summary of the invention
[0006] The technical problem solved by the present invention is to provide an integrated device of a purification column and a valve body pipeline with a simple pipeline design, low leakage and space saving, which can make the glove box lighter and more convenient to use, transport and maintain.
[0007] In order to solve the above technical problems, the present invention provides an integrated device of a purification column and a valve body pipeline, comprising a purification column, an air inlet high vacuum baffle valve, an air outlet high vacuum baffle valve and an integrated valve group, wherein the air inlet high vacuum baffle valve and the air outlet high vacuum baffle valve are arranged side by side at the top of the purification column, the integrated valve group is arranged behind the air inlet high vacuum baffle valve and the air outlet high vacuum baffle valve, the air inlet high vacuum baffle valve and the air outlet high vacuum baffle valve are sealed and installed with the integrated valve group, and the lower half of the integrated valve body is sealed and connected with the air inlet channel and the air outlet channel inside the purification column respectively. The integrated valve group is connected with a working gas pipeline and a regeneration pipeline.
[0008] When the glove box is working, the gas in the box flows through the high vacuum baffle valve at the air inlet and into the purification column through the integrated valve group. The purification column is filled with molecular sieves and copper catalysts, which can absorb oxygen and moisture in the air. The filtered air then flows back to the glove box through the integrated valve group and the high vacuum baffle valve at the air outlet.
[0009] Furthermore, the air inlet high vacuum baffle valve and the air outlet high vacuum baffle valve are arranged side by side on the upper part of the purification column.
[0010] Furthermore, the working gas pipeline and the regeneration pipeline are connected to the integrated valve group.
[0011] The beneficial effects of the invention are that the pipeline design is simple, not prone to leakage, and saves space, and can make the glove box lighter and more flexible, and more convenient to use, transport and maintain. BRIEF DESCRIPTION OF THE DRAWINGS
