Description

Technical Field

[0001] This utility model relates to the field of glove box technology, and in particular to a glove box powder cleaning device. Background Technology

[0002] A glove box is a laboratory or industrial production equipment that provides a water-free, oxygen-free, and dust-free environment, and is widely used in fields such as lithium battery research and development and production, materials science, and chemical synthesis. During the use of a glove box, especially when handling powdered materials, the powder easily adheres to the inner wall of the glove box, the surface of the operating gloves, and the surface of the equipment placed inside. Existing powder removal methods mainly rely on manual operation, which is not only inefficient but also makes it difficult to clean hard-to-reach areas (such as corners and gaps between equipment and the box), resulting in powder residue. Furthermore, the cleaning process can easily generate secondary dust, which can not only re-contaminate the clean environment inside the glove box but may also affect the accuracy of subsequent experiments or production processes. Utility Model Content

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0016] Example: Please see Figure 1 - Figure 5 This utility model provides a technical solution: a glove box powder cleaning device, including a printing chamber 1, which is a closed space seamlessly connected to a 3D printer. An airflow distributor is installed inside the printing chamber 1 to ensure the uniformity of inert gas entering the printing chamber 1 and prevent excessive turbulence. An air inlet 11 is located at the top left end of the printing chamber 1, and the output end of the air inlet 11 is connected to the airflow distributor. An air supply port 12 and an air suction port 13 are located at the top left end of the printing chamber 1. A suction hood is fixedly connected to the input end of the air suction port 13, and the suction hood is located inside the printing chamber 1. An exhaust port 18 for discharging inert gas is located at the top right end of the printing chamber 1, and an air inlet 14 is located at the top left end of the printing chamber 1. The top right end is equipped with an air intake 17 and an air supply 19. The printing chamber 1 is equipped with an oxygen concentration monitor 15 and a pressure sensor 16. During operation, inert gas (such as nitrogen or argon) is introduced into the printing chamber 1 to maintain a negative pressure environment and prevent powder oxidation or escape. Both air intake 13 and air intake 17 automatically clean the dust inside the chamber through suction hoods. For trace amounts of residue in complex structures (such as internal holes and hollow areas), the operator can manually handle them by opening the sealed glove interface of the printing chamber 1. During the process of inert gas being discharged into the printing chamber 1, the oxygen concentration monitor 15 and the pressure sensor 16 monitor the internal condition of the printing chamber 1 in real time. If it is higher than the standard value, the air supply 12 and air supply 19 will increase the discharge of inert gas in real time.

[0017] The bottom of the printing chamber 1 is symmetrically provided with toner drop troughs 4. The inner wall of the toner drop trough 4 is fixedly connected with a toner drop baffle 5. The bottom of the printing chamber 1 is fixedly connected with a toner collection cover 10. The toner collection cover 10 is located outside the toner drop trough 4. The toner drop baffle 5 guides the falling powder to collect and prevents the powder that has fallen to the bottom from being thrown up again due to airflow disturbance. The toner collection cover 10 further gathers the powder collected by the two toner drop troughs 4 to the central outlet at the bottom of the chamber, which is convenient for centralized recycling. The left and right side walls of the printing chamber 1 are equipped with side door frames 6, and the inner walls of the side door frames 6 are fixedly connected with side viewing windows 7. The front side wall of the printing chamber 1 is equipped with two front door frames 8, and the inner walls of the two front door frames 8 are fixedly connected with front viewing windows 9. Both the side viewing windows 7 and the front viewing windows 9 are equipped with sealed glove interfaces of standard specifications. Operators can operate the equipment and perform auxiliary operations such as powder cleaning by wearing sealed gloves without disturbing the inert atmosphere inside the chamber. The bottom of the printing chamber 1 has an opening 2, which provides space for the lifting and lowering of the formed workpiece. A connecting plate 3 is fixedly connected to the bottom of the printing chamber 1, and the connecting plate 3 is located outside the opening 2. The connecting plate 3 is sealed to the lower equipment, ensuring the airtightness of the entire system's working cavity.

[0018] In this implementation scheme, after 3D printing is completed, the printing platform is automatically transferred to the printing chamber 1, the chamber door is sealed, and inert gas enters the printing chamber 1 through the air inlet 11 via the airflow distributor to replace the air inside the chamber, ensuring that the metal powder is not oxidized or preventing the diffusion of toxic powder. The oxygen concentration monitor 15 and pressure sensor 16 installed on the printing chamber 1 monitor the oxygen content inside the chamber in real time to ensure that it is always maintained below the safe threshold that prevents the metal powder from oxidizing. The pressure sensor 16 is used to monitor the air pressure inside the chamber and, through linkage with the air intake and exhaust systems, stabilizes the pressure inside the chamber at a positive pressure state slightly higher than the external atmospheric pressure to prevent the infiltration of external air. During powder cleaning, the operator operates with gloves and simultaneously starts the airflow system to introduce inert gas into the printing chamber 1 through the air inlet 11. After being evenly distributed by the airflow distributor, the remaining powder in the printing chamber 1 is blown away. The raised powder falls into the powder collection hood 10 through the powder dropper 4 under the guidance of gravity and airflow. The first suction port 13 and the second suction port 17 can be activated as needed to enhance the local powder suction effect. During this process, oxygen concentration and pressure are continuously monitored to ensure operational safety.

[0019] Working principle: After 3D printing is completed, the printing platform is automatically transferred to the printing chamber 1. Then, inert gas (such as nitrogen or argon) is introduced into the printing chamber 1 to maintain a negative pressure environment to prevent powder oxidation or escape. Both suction vent 13 and suction vent 2 17 automatically clean the dust inside the chamber through suction hoods. For trace residues in complex structures (such as internal holes and hollow areas), the operator can manually handle them by opening the sealed glove interface of the printing chamber 1. During the process of inert gas being discharged into the printing chamber 1, the oxygen concentration monitor 15 and pressure sensor 16 monitor the internal condition of the printing chamber 1 in real time. If it is higher than the standard value, the amount of inert gas discharged will be increased in real time by the replenishment air vent 12 and replenishment air vent 2 19 to ensure that it is always maintained below the safe threshold for preventing metal powder oxidation. Pressure sensor 16 is used to monitor the air pressure inside the chamber and, through linkage with the air intake and exhaust system, stabilizes the pressure inside the chamber at a positive pressure state slightly higher than the external atmospheric pressure to prevent external air from seeping in. During the cleaning process, the operator operates the equipment while simultaneously activating the airflow system. Inert gas is introduced into the printing chamber 1 through the air inlet 11. After being evenly distributed by the airflow distributor, the remaining powder in the printing chamber 1 is swept away. The powder that is lifted falls into the powder collection hood 10 through the powder dropper 4 under the guidance of gravity and airflow, making it easy to collect.
