[0005] In the embodiment of the present application, the flow guide device comprises a flow guide plate and a heating device; The flow guide plate and the heating device are arranged between the box body and the gas inlet.

[0006] In the embodiment of the present application, the inert gas glove box further comprises a cooling device, the electrode dust collection device comprises a face array substrate and a metal tip, and the metal tip is connected with the face array substrate; The cooling device is used to cool the face array substrate.

[0007] In the embodiment of the present application, the metal tips are arranged on the face array substrate in an array manner.

[0008] In this embodiment of the application, the inert gas glove box further includes a first valve, which is disposed between the gas inlet and the discharge box; The first valve is used to control the flow between the gas inlet and the discharge box.

[0009] In this embodiment of the application, the inert gas glove box further includes a second valve, which is disposed between the discharge box and the gas outlet; The second valve is used to control the flow between the discharge box and the gas outlet.

[0010] In this embodiment of the application, the inert gas glove box further includes a third valve, which is disposed between the discharge box and the dust collection device; The third valve is used to control the flow between the discharge box and the dust collection device.

[0020] Combination Figure 1This application describes an inert gas glove box provided in an embodiment, comprising a box body 1, a dust removal pipe 2, a flow guiding device 3, an electrode dust collection device 4, and a dust collection device 5. The dust removal pipe 2 includes a gas inlet 21, a discharge box 22, and a gas outlet 23, which are respectively connected to the box body 1. The flow guiding device 3 is used to guide the gas in the box body 1 to the gas inlet 21, so that the airflow flows sequentially through the discharge box 22 and the gas outlet 23. The electrode dust collection device 4 is disposed inside the discharge box 22, and the charge carried by the electrode dust collection device 4 is opposite to the discharge charge of the discharge box 22. The dust collection device 5 is disposed below the discharge box 22 and the gas outlet 23, and is connected to the dust removal pipe 2.

[0021] In a specific embodiment of this application, the housing 1 contains inert gas; the inert gas can be used for dust removal after flowing through the dust removal pipe 2; specifically, the inert gas flows into the dust removal pipe 2 from the gas inlet 21 under the guidance of the flow guiding device 3, and then flows to the discharge box 22. The discharge box 22 continuously discharges, so that the dust in the gas becomes charged, and the dust is adsorbed onto the electrode dust collection device 4 by utilizing the principle of opposite charges attracting each other. As the dust is adsorbed and accumulated, the dust falls into the dust collection device 5 under the action of gravity, thereby realizing the dust removal of the inert gas.

[0022] In a specific embodiment of this application, the discharge box 22 is connected to a DC high-voltage power supply to form a high-intensity electric field around the electrode dust collection device 4. Under the action of the strong electric field, the small amount of free ions in the air gain energy and accelerate, colliding with neutral atoms, causing the neutral atoms to decompose into positive and negative ions, and then continuously charging to form a corona region.

[0023] In a specific embodiment of this application, the voltage value of the DC high-voltage power supply is selected based on actual needs; preferably, the voltage value of the DC high-voltage power supply is 20 kV.

[0024] In a specific embodiment of this application, the electrode dust collection device 4 is grounded as the positive electrode.

[0025] In specific embodiments of this application, the inert gas glove box is also referred to as an inert gas operating box and a vacuum glove box, etc.

[0026] In one specific embodiment of this application, the dust collection device 5 can be detachably connected to the dust removal pipe 2, and a sealing structure is provided at the connection between the dust collection device 5 and the dust removal pipe 2 to ensure the airtightness of the inert gas glove box; specifically, during the cleaning process of the inert gas glove box, only the dust collection device 5 can be disassembled for cleaning.

[0027] In one specific embodiment of this application, the dust collection device 5 may also be integrated with the dust removal pipe 2.

[0028] In this embodiment, by setting up a flow guiding device 3, a dust removal pipe 2 including a discharge box 22, and an electrode dust collection device 4, the dust in the gas flows through the dust removal pipe 2 in the box 1. The dust in the gas carries a charge in the surge area of ​​the discharge box 22 and is attracted to the electrode dust collection device 4 with the opposite charge, adhering to the electrode dust collection device 4. As the amount of dust attached increases, the dust falls into the dust collection device 5 under the influence of gravity, thereby removing dust from the gas. This dust removal process keeps the operating surface inside the glove box in a high-clean state, improving experimental accuracy and production quality. At the same time, it can maintain dust removal work for a longer period of time, reducing equipment maintenance costs. It can also adsorb smaller dust particles and improve dust removal efficiency.

[0031] In a specific embodiment of this application, when the heating device 32 is working, the inert gas forms an airflow due to the temperature difference and then flows into the dust removal pipe 2.

[0032] In this embodiment, the inert gas is guided by a heating device 32 and a guide plate 31. The principle of temperature difference is used to guide the flow, which reduces the dust retention of dust flowing through the guide device 3, thereby improving the dust removal accuracy, experimental accuracy and production quality. At the same time, the absence of worn moving parts increases the service life of the inert gas glove box.

[0033] In a specific embodiment of this application, the inert gas is guided by a heating device 32 and a guide plate 31. The guiding principle is based on temperature difference. The gas flow rate is small, which helps to maintain the stability of the gas pressure and the uniform gas flow in the glove box. It can be easily used in conjunction with oxygen adsorbers, water adsorbers, etc., to maintain the high purity of the environment inside the box.

[0034] In another specific embodiment of this application, the flow guiding device 3 may further include an airflow driving device to drive the airflow into the dust removal pipe 2.

[0036] In a specific embodiment of this application, when the gas heated by the heating device 32 comes into contact with the cooled array substrate 41, it forms a downward airflow, which flows into the housing 1 from the gas outlet 23.

[0037] In a specific embodiment of this application, the area array substrate 41 is cooled by the cooling device 6, thereby using the principle of temperature difference to guide the flow, thus forming a circulating airflow in conjunction with the heating device 32, thereby realizing the cyclic removal of dust from the inert gas, improving the dust removal accuracy, and improving experimental accuracy and production quality.

[0038] In a specific embodiment of this application, the area array substrate 41 is cooled by the cooling device 6, thereby using the principle of temperature difference to guide the airflow. The airflow is small, which helps to maintain the stability of the air pressure and the uniform gas flow in the glove box. It can be easily used in conjunction with oxygen adsorbers, water adsorbers, etc., to jointly maintain the high purity of the environment inside the box.

[0039] In this embodiment, metal tips 42 are arranged in an array on the area array substrate 41.

[0040] In this embodiment, by arranging the metal tips 42 in an array on the area array substrate 41, the contact surface with dust in the gas is increased, the dust capacity is increased, and the dust collection efficiency is improved, thereby improving experimental accuracy and production quality.

[0045] In this embodiment, by setting the first valve 7, the internal environment of the glove box is avoided from being affected during the dust cleaning process, thereby improving the environment inside the glove box to always maintain a high level of purification, thus improving experimental accuracy and production quality.

[0046] In this embodiment of the application, the inert gas glove box further includes a second valve 8, which is disposed between the discharge box 22 and the gas outlet 23; the second valve 8 is used to control the flow state between the discharge box 22 and the gas outlet 23.

[0047] In a specific embodiment of this application, the second valve 8 is normally open during the operation of the inert gas glove box, and is closed when cleaning and replacing the dust collection device 5, so as to prevent the external environment from affecting the environment inside the glove box.

[0048] In a specific embodiment of this application, the second valve 8 is a high-vacuum sealed valve.

[0049] In this embodiment, by setting a second valve 8, the internal environment of the glove box is avoided from being affected during the dust cleaning process, thereby improving the environment inside the glove box to always maintain a high level of purification, thus improving experimental accuracy and production quality.

[0050] In this embodiment, the inert gas glove box further includes a third valve 9, which is disposed between the discharge box 22 and the dust collection device 5; the third valve 9 is used to control the flow state between the discharge box 22 and the dust collection device 5.
