Description

Technical Field

[0001] The utility model relates to the technical field of gas circulation in glove boxes, and specifically relates to a glove box compartment. Background Art

[0002] A glove box is a sealed container, and the compartment in the glove box usually refers to an independent compartment inside the glove box, which is used for specific experiments or operations. The compartment plays an important role in the glove box. Researchers often complete some specific experimental operations through the specific environment in the compartment. Therefore, the requirement for the gas purity in the compartment is higher.

[0003] First of all, the position of the compartment is relatively low, and it is almost impossible for the convection of the gas in the box to make the gas in the compartment fully convect with the gas in the box, and the outer door cannot guarantee its sealing effect. Whether water and oxygen will continue to leak is unknown. In this way, it is difficult to judge whether the local operating environment of the compartment meets the standards, and the gas circulation between the inside of the compartment and the box body becomes extremely important.

[0004] Secondly, the commonly used circulating adsorption system in glove boxes refers to circulating the gas inside the box and adsorbing the possible water and oxygen. However, when the gas in the box circulates, the gas exchange with the inside of the glove box compartment is not considered, which makes it difficult for the gas inside the compartment to circulate, and is extremely unfavorable to the stability of the gas composition inside it.

[0005] Finally, since the compartment is at the bottom of the glove box and is less affected by the box body circulation, and the internal structure of the compartment is complex, it is more difficult for the gas to flow between the inside of the compartment and the box body under the influence of a series of operating devices. Therefore, solving the problem of poor gas fluidity in the compartment is particularly important for the overall glove box. Content of the Utility Model

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. Embodiment

[0030] Please refer to Figures 1 - 6 , a glove square bin, comprising a glove box 1, a control mechanism, a gas exchange mechanism and a sealing mechanism, characterized in that the control mechanism includes an inner door 2, a proximity switch 3, a moving guide rail 4, a fixing bracket 5 and a screw handle 6, the inner door 2 is arranged inside the glove box 1 and is detachably connected to the glove box 1, the moving guide rail 4 is fixedly installed inside the glove box 1 and is located on both sides of the inner door 2, the proximity switch 3 is fixedly installed on the glove box 1, the fixing bracket 5 is installed on the moving guide rail 4 and is slidably connected to the moving guide rail 4, the screw handle 6 is installed on the fixing bracket 5 and is threadedly connected to the fixing bracket 5, and one end of the screw handle 6 passes through the fixing bracket 5 and is rotatably connected to the inner door 2; the gas exchange mechanism includes a square bin 7, a rotary angle valve 8, a circulation fan 9 and a connecting pipeline, the square bin 7 is arranged at the bottom end of the glove box 1, the rotary angle valve 8 is installed on the KF25 interface 10 and is detachably connected to the KF25 interface, the rotary angle valve 8 is fixedly connected to the connecting pipeline, and the circulation fan 9 is arranged at the bottom of the glove box 1 and is detachably connected to the connecting pipeline.

[0031] In this embodiment, the control mechanism includes an inner door 2, a proximity switch 3, a moving guide rail 4, a fixing bracket 5, and a screw handle 6. The inner door 2 is linked to the rotary angle valve 8 through the proximity switch 3. When the inner door 2 is closed, the rotary angle valve 8 is in the closed state. When the inner door 2 is opened, the rotary angle valve 8 is opened. During use, both hands pass through the glove ports 19 of the observation openings on the glove box 1 and start turning the screw handle 6. The screw handle 6 rotates on the fixing bracket 5. Due to the threaded connection between the screw handle 6 and the fixing bracket 5, the screw handle 6 slowly rises on the fixing bracket 5. The inner door 2 threaded to the screw handle 6 slowly rises under the rotation of the screw handle 6 and finally separates from the glove box 1. At this time, the connection switch installed on the moving guide rail 4 sends a command to the rotary angle valve 8 after sensing the rise of the inner door 2, thereby opening the rotary angle valve 8. At this time, move the fixing bracket 5 located on the moving guide rail 4 and start the next step of processing the object. After the processing is completed, move back through the moving fixing bracket 5, align the inner door 2 with the glove box 1, and then turn the screw handle 6 again. The inner door 2 is placed into the glove box 1. At this time, the connection switch detects that the inner door 2 is closed and then sends a command to close the rotary angle valve 8, thus completing the task of the operation of the control mechanism.

[0032] In this embodiment, the gas exchange mechanism includes a square bin 7, a rotary angle valve 8, a circulation fan 9, and a connecting pipeline. The connecting pipeline includes a first pipeline 12 and a second pipeline 13. During use, according to the operation of the above control mechanism, the rotary angle valve 8 is opened. On this basis, the rotary angle valve 8 is linked to the circulation fan 9. When the rotary angle valve 8 is opened, the circulation fan 9 is started synchronously. The first pipeline 12 detachably connected to the rotary angle valve 8 is affected by the circulation fan 9 and extracts the gas inside the square bin 7, and then transports the gas to the circulation fan 9. When the circulation fan 9 receives the gas from the square bin 7, it starts purification and adsorption, and then discharges the gas meeting the environmental standards into the second pipeline 13. The gas enters the glove box 1 through the second pipeline 13, thereby completing the process of gas exchange.

[0033] In this embodiment, the sealing mechanism includes a KF25 interface 10 and a KF40 interface 11. The KF25 is fixedly installed on one side of the square bin 7. The rotary angle valve 8 is detachably connected to the square bin 7 through the KF25 interface 10, and the rotary angle valve 8 is fixedly connected to the first pipeline 12. The KF40 interface 11 is fixedly installed on the side of the glove box 1 and is detachably connected to the second pipeline 13. An air inlet 14 and an air outlet 15 are provided at the top of the circulation fan 9. During use, the KF25 interface 10 clamps the rotary angle valve 8, so that the rotary angle valve 8 is fixedly connected to the first pipeline 12. At the same time, the other end of the first pipeline 12 is fixedly connected to the air inlet 14 on the circulation fan 9, and the air outlet 15 on the circulation fan 9 is fixedly connected to one end of the second pipeline 13. The other end of the second pipeline 13 is detachably connected to the KF40 interface 11 fixedly installed outside the glove box 1, thus completing the sealing of the pipeline, so as to ensure that gas will not leak when the above mechanism operates.

[0034] In this embodiment, the glove box 1 is provided with a control panel 16, an air circulation pipeline 17, an observation window 18 and glove ports 19. During use, the staff can operate the gas exchange mechanism and control the operation of the control mechanism through the control panel 16, and observe the change of gas composition and gas convection inside the glove box 1 through the control panel 16. The air circulation pipeline 17 circulates the gas inside the glove box 1, and the direction of the circulating gas inside the glove box 1 is opposite to the connection direction between the square bin 7, the first pipeline 12, the second pipeline 13 and the glove box 1. When the gas environment inside the glove box 1 is stable, the staff can put both hands into the glove ports 19 on the observation window 18 of the glove box 1, so as to start operating the object to be processed or treated. Embodiment

[0035] In summary, during use, we can first make sealed and fixed connections among various connecting pipelines, the glove box 1, the circulation fan 9, and the rotary angle valve 8. During use, the KF25 interface 10 clamps the rotary angle valve 8 to achieve a detachable connection between the rotary angle valve 8 and the KF25 interface 10. One end of the first pipeline 12 is fixedly connected to the rotary angle valve 8, and at the same time, the other end of the first pipeline 12 is fixedly connected to the air inlet 14 on the circulation fan 9. The air outlet 15 on the circulation fan 9 is fixedly connected to one end of the second pipeline 13, and the other end of the second pipeline 13 is detachably connected to the KF40 interface 11 fixedly installed outside the glove box 1. Thus, the sealing of the pipeline is completed, ensuring that gas will not leak during the operation of the rest of the mechanism. When the sealing is confirmed, the object to be processed is started to be processed. At this time, the object is placed inside the square bin 7. When the square bin 7 is opened, external gas enters, affecting the air composition inside the square bin 7. At this time, the gas exchange mechanism starts to operate, and the rotary angle valve 8 is linked with the circulation fan 9. When the rotary angle valve 8 is opened, the circulation fan 9 starts synchronously. The first pipeline 12 fixedly connected to the rotary angle valve 8 is affected by the circulation fan 9, extracting the gas inside the square bin 7 and then transporting the gas to the circulation fan 9. When the circulation fan 9 receives the gas from the square bin 7, it starts purification and adsorption, and then discharges the gas meeting the processing work standard into the second pipeline 13. The gas enters the glove box 1 through the second pipeline 13, thus completing the gas exchange process. On this basis, by observing the gas composition analysis on the control panel 16, one can process or process the object by putting both hands through the glove ports 19 on the observation window 18. At this time, both hands pass through the glove ports 19 at the observation opening on the glove box 1, and start to turn the screw handle 6. The screw handle 6 rotates on the fixed frame 5. Due to the threaded connection between the screw handle 6 and the fixed frame 5, the screw handle 6 slowly rises on the fixed frame 5, and the inner door 2 rotationally connected to the screw handle 6 slowly rises under the rotation of the screw handle 6 and finally separates from the glove box 1. At this time, the connection switch installed on the moving guide rail 4 will send a command to the rotary angle valve 8 after sensing the rise of the inner door 2, thus opening the rotary angle valve 8. At this time, move the fixed frame 5 located on the moving guide rail 4 to start the next step of processing the object. When the processing is completed, move back the fixed frame 5 through the movement, align the inner door 2 with the glove box 1, and then turn the screw handle 6 again to put the inner door 2 into the glove box 1. At this time, the connection switch detects that the inner door 2 is closed, and then sends a command to close the rotary angle valve 8, thus cooperating with the above gas exchange mechanism to complete the entire gas circulation process inside the glove box 1. In addition, when the glove box 1 is working, the air circulation pipeline 17 circulates the gas inside the glove box 1, and the direction of the circulating gas inside the glove box 1 is opposite to the connection direction among the square bin 7, the first pipeline 12, the second pipeline 13, and the glove box 1, thus ensuring the stable convection of the gas in the glove box 1.

[0036] Among all the solutions mentioned above, for those involving the connection between two components, welding, connection with bolts and nuts, connection with bolts or screws, or other well-known connection methods can be selected according to the actual situation, which will not be elaborated one by one here. For those involving fixed connection mentioned above, welding is preferably considered. Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
