Description

Technical Field

[0001] This invention relates to the field of vacuum glove box technology, specifically to a vacuum glove box system with inert gas replenishment, suitable for experimental and production scenarios requiring a water-free, oxygen-free, and dust-free environment, such as new material synthesis, precision electronic component processing, and chemical experiments. Background Technology

[0002] In high-end fields such as scientific research and precision manufacturing, sensitive materials, precision devices and special chemical reactions need to be carried out in an ultrapure environment that is free of water, oxygen and dust. As a core control device, the vacuum glove box is widely used in fields such as new energy batteries, semiconductors and biomedicine. It is an essential piece of equipment for high-end industries and scientific research activities. The vacuum glove box, also known as an inert gas protection box, is a fully enclosed environmental control system. Its core function is to remove impurities such as oxygen and moisture from the box through vacuum extraction, inert gas replenishment and filling and circulation purification, so as to maintain an ultrapure operating environment. However, existing publicly available vacuum glove boxes still have some shortcomings in practical applications that need to be improved, such as: 1. The upper chamber and the supporting platform are mostly designed as one piece or fixed connection, which cannot be quickly disassembled. When the inner wall of the chamber is contaminated due to experimental operation, the upper chamber and the platform cannot be separated for thorough cleaning, which can easily leave contaminants and affect the accuracy of subsequent experiments. Moreover, when the upper chamber is damaged or the seal fails, the entire combination structure of the upper chamber and the platform needs to be replaced. This not only makes the replacement process cumbersome, time-consuming and labor-intensive, but also significantly increases the equipment maintenance cost. 2. The glove mounting ring is usually directly assembled to the mounting port of the upper box by welding, bolting or other fixing methods, which cannot be quickly disassembled. When the glove mounting ring is damaged, the sealing ring ages and leaks, or the glove body is damaged and needs to be replaced along with the mounting ring, part of the upper box structure must be disassembled to complete the replacement. This is not only inconvenient to operate, but also makes it impossible to restore the equipment to normal use in a timely manner, thus affecting the experimental progress.

[0003] Therefore, those skilled in the art have provided a vacuum glove box system with inert gas replenishment to solve the problems mentioned in the background art.

[0004] To address the shortcomings of existing technologies, this invention provides a vacuum glove box system with inert gas replenishment, which solves the problems mentioned in the background section.

[0009] As a further technical solution of the present invention, the hand access mechanism includes a mounting ring, on which a glove body is sleeved, and an outer rubber ring is sleeved on the outside of the mounting ring, and the glove body is fixed to the mounting ring by the rubber ring; An inner sealing ring is provided at the outer rear end of the mounting ring, an outer sealing ring is slidably disposed on the mounting ring, and a locking ring is screwed into the outer thread of the mounting ring.

[0010] As a further technical solution of the present invention, the front side of the inner sealing ring is pressed and disposed inside the housing, the outer sealing ring is pressed and disposed on the front side of the housing, and the mounting ring is slidably disposed inside the mounting opening. The inner and outer sealing rings form a double sealing structure, which can effectively improve the sealing performance between the hand access mechanism and the housing and prevent inert gas leakage; the rubber ring is used to fix the glove body, which facilitates the individual replacement of the glove body; in addition, the locking ring is used to press the outer sealing ring to ensure the sealing effect, and at the same time facilitates the disassembly and assembly of the hand access mechanism.

[0011] As a further technical solution of the present invention, the slide rod passes through the operating table and is slidably disposed inside the positioning hole, and the stop block is pressed and disposed on the outside of the operating table to ensure the fixing effect of the positioning mechanism on the insert block and prevent the vacuum glove box mechanism from loosening during use.

[0013] This invention provides a vacuum glove box system with inert gas replenishment, which has the following advantages compared with the prior art: 1. This design presents a vacuum glove box system with inert gas replenishment. The positioning of the support mechanism and the vacuum glove box mechanism is achieved through the insertion and engagement of slots and inserts. The positioning mechanism fixes the inserts into the slots, locking the support mechanism and the vacuum glove box mechanism together. This allows the vacuum glove box mechanism and the support mechanism to be separated, facilitating thorough cleaning of the inner wall of the box and the operating table, preventing contaminant residue, and effectively improving experimental accuracy. Furthermore, in case of damage to the upper box or seal failure, the vacuum glove box mechanism can be replaced separately without replacing the entire device, simplifying the maintenance process and reducing equipment maintenance costs.

[0014] 2. This design provides a vacuum glove box system with inert gas replenishment. A sealing gasket is installed between the insertion block of the vacuum glove box mechanism and the slot of the supporting mechanism. An inner sealing ring and an outer sealing ring are installed between the hand access mechanism and the box body to form a double sealing structure, which effectively avoids inert gas leakage, ensures the stability of the experimental environment, solves the problem of poor sealing performance in the prior art, and reduces the safety hazards caused by gas leakage.

[0015] 3. This design provides a vacuum glove box system with inert gas replenishment. The hand access mechanism adopts a detachable design. The glove body is fixed by a rubber ring, and the locking ring presses the outer sealing ring. When the glove body is damaged or the hand access mechanism leaks, it can be quickly disassembled and replaced without disassembling a large number of parts. Moreover, the vacuum glove box mechanism is detachably connected to the bearing mechanism through a positioning mechanism. Pulling the limit block can release the positioning, and lifting the box can complete the disassembly, which facilitates the cleaning of the operating table and the inner wall of the box, greatly improving the cleaning and maintenance efficiency and solving the problems of cumbersome disassembly and inconvenient cleaning in the existing technology.

[0016] 4. This design provides a vacuum glove box system with inert gas replenishment. The inert gas tank is connected to the box body through an inert gas output pipe and a connector, which can continuously and stably replenish the box body with inert gas, ensuring that the box body always maintains a stable anhydrous and oxygen-free environment, thus ensuring the accuracy of experimental results. It is suitable for scenarios with high requirements for experimental environment. Attached Figure Description
