Description

Technical Field

[0001] The utility model belongs to the technical field of experimental equipment, in particular to an inert gas glove operating box. Background Art

[0002] Inert gas glove boxes are frequently used in scientific research and laboratory work. For example, during the chemical synthesis of small nucleic acids and their specific chemical modification, strict control of oxygen and moisture levels is required to prevent disruption of the synthesis reaction or degradation of the nucleic acids. An inert gas glove box provides a stable, oxygen- and water-free environment, ensuring smooth synthesis and modification.

[0003] The invention discloses an inert gas glove operation box disclosed in the utility model patent with the authorized patent announcement number CN209850977U, which includes a closed box body, a glove hole, a rectangular swing door, a rectangular sliding door, a vacuum valve, an inflation valve, a vacuum pressure gauge and a power socket. The vacuum valve and the inflation valve are arranged at the upper left corner of the top of the box body; the rectangular swing door is located on the right side of the top of the box body, which is convenient for placing larger items into the box body; the rectangular sliding door is arranged at the lower left corner of the box body. However, if experimental materials are to be taken out and placed in this type of operation box during the experiment, the inert gas environment inside the box body will be destroyed when the swing door or the sliding door is opened. At the same time, some experimental materials need to be temporarily stored in the inert gas, and the space inside the box is large, so more inert gas is required, which is easy to cause waste. Therefore, an inert gas glove operation box is needed that can not destroy the experimental operation environment during the experimental operation and can facilitate the temporary storage of experimental materials. Utility Model Content

[0004] In response to the above problems, the present invention proposes an inert gas glove operation box, which effectively solves the problems in the prior art that taking and placing experimental materials during the experiment easily destroys the inert gas environment and the inconvenience of the inert gas operation box for temporary storage of experimental materials.

[0005] In order to achieve the above-mentioned objectives, the technical solution adopted by the present invention is as follows: an inert gas glove operation box, comprising an operation chamber and a transition chamber, wherein a first closed door that can be opened and closed is sealed between the operation chamber and the transition chamber, and a second closed door that can be opened and closed is sealed on the side of the transition chamber, an air intake pipe is connected to the transition chamber, an air intake switch is provided on the air intake pipe, a connecting pipe connected to the operation chamber is provided on the transition chamber, a connecting switch is provided on the connecting pipe, an exhaust pipe is provided on the operation chamber, and an exhaust switch is provided on the exhaust pipe.

[0006] Furthermore, the operation chamber and the transition chamber are boxes formed by gluing and sealing transparent acrylic plates, and the transparent acrylic plates facilitate observation of the drugs in the operation chamber for experimental operations.

[0007] Furthermore, a window panel is provided at the connection between the front side and the upper side of the operating compartment. The window panel is tilted to provide a good observation field of view and avoid the joint affecting the line of sight.

[0008] Furthermore, the operating chamber includes a chamber body and a rubber glove connected to the front side of the chamber body. The rubber glove is located inside the chamber body and the inside of the rubber glove is connected to the outside of the chamber body. Experiments are performed in the operating chamber through the set rubber gloves to ensure the experimental environment in the operating chamber.

[0009] Furthermore, a closed door three is provided on the side of the warehouse body, and the closed door three is provided to facilitate the entry or removal of larger experimental equipment.

[0010] Furthermore, the connecting pipe is close to the lower side of the transition chamber, and the exhaust pipe is close to the lower side of the operation chamber. Helium is generally used as the experimental atmosphere gas in the laboratory. Since the density of helium is lower than that of air, the lower-set connecting pipe and exhaust pipe help to fill the operation chamber and the transition chamber with inert gas.

[0011] Furthermore, the transition chamber is located inside the operating chamber, the second closed door is located on the side of the operating chamber, the air intake duct is connected to the outside of the operating chamber, the air intake switch is arranged on the air intake duct outside the operating chamber, and the transition chamber is arranged inside the operating chamber. Although a part of the operating chamber space is reduced, the overall size of the equipment is reduced, and at the same time, the transition chamber is prevented from being hit and causing damage to the seal at the connection between the transition chamber and the operating chamber.

[0012] Furthermore, an air pressure relief valve is installed on the operating chamber, and the operating chamber is stabilized in a slightly positive pressure environment through the air pressure relief valve.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] The utility model can take out or put in medicines or experimental instruments through the provided transition chamber, thereby avoiding damaging the experimental environment in the operation chamber and reducing the waste of inert gas. At the same time, the provided transition chamber can be used to temporarily store medicines or experimental materials, so the required inert gas is correspondingly less, saving the use of inert gas.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] Example 1:

[0020] like Figure 1 As shown, an inert gas glove operation box includes an operation chamber 1 and a transition chamber 2. The left side of the transition chamber 2 is attached to the right side of the operation chamber 1 and fixedly connected by glue. The side of the transition chamber 2 attached to the operation chamber 1 is provided with a passage connecting the operation chamber 1 and the transition chamber 2. The inner side of the operation chamber 1 is provided with a closed door 3 located at one part of the passage. The closed door 3 is connected to the operation chamber 1 by a hinge. At this time, the closed door 3 can be rotated to the inside of the operation chamber 1 to open. The side of the closed door 3 attached to the inner wall of the operation chamber 1 is provided with a sealing ring. The side of the closed door 3 away from the hinge is provided with a switch lock. The switch lock can be a hasp, a press switch or the like. When the closed door 3 fits against the inner wall of the operating chamber 1, the sealing ring is squeezed to form a seal. At this time, the switch lock locks and keeps the closed door 3 in a closed state. The right side of the transition chamber 2 is also equipped with a closed door 4 that can be rotatably opened and closed by setting hinges, sealing rings and switch locks. The transition chamber 2 is connected to an air intake pipe 5, and an air intake switch 6 is set on the air intake pipe 5. The transition chamber 2 is provided with a connecting pipe 7 connected to the operating chamber 1, and a connecting switch 8 is set on the connecting pipe 7. The operating chamber 1 is provided with an exhaust pipe 9, and an exhaust switch 10 is set on the exhaust pipe 9. The air intake switch 6, the connecting switch 8 and the exhaust switch 10 all use ball valve switches.

[0021] In this embodiment, the operation chamber 1 and the transition chamber 2 are boxes formed by gluing and sealing transparent acrylic plates.

[0022] In this embodiment, a window panel 101 is provided at the connection between the front side and the upper side of the operating compartment 1 , and the window panel 101 is tilted.

[0023] In this embodiment, the operation warehouse 1 includes a warehouse body 102, and two operation holes are opened on the front side of the warehouse body 102. A rubber glove 103 is set inside the warehouse body 102 at the operation holes. The cuffs of the rubber glove 103 are sealed with the operation holes by glue. At this time, the rubber glove 103 is located inside the warehouse body 102 and the inside of the rubber glove 103 is connected with the outside of the warehouse body 102.

[0024] In this embodiment, a closed door 3 11 is provided on the side of the warehouse body 102 . The closed door 3 11 is provided in the same manner as the closed door 1 3 and the closed door 2 4 , and is not described in detail here.

[0025] In this embodiment, the communication pipe 7 is close to the lower side of the transition chamber 2 , and the exhaust pipe 9 is close to the lower side of the operation chamber 1 .

[0026] In this embodiment, an air pressure relief valve 12 is installed on the operating compartment 1 .

[0027] Example 2:

[0028] like Figure 2 As shown, the difference between this embodiment and embodiment 1 is that the transition chamber 2 is located in the operating chamber 1, the transition chamber 2 is located at the corner of the operating chamber 1, the closed door 2 4 is located on the side of the operating chamber 1, the air intake duct 5 is connected to the outside of the operating chamber 1, and the air intake switch 6 is arranged on the air intake duct 5 outside the operating chamber 1.

[0029] When the present invention is in use, if it is necessary to temporarily store experimental materials, the experimental materials can be placed in the transition chamber 2, the air inlet switch 6 and the connecting switch 8 are opened, and the transition chamber 2 is filled with inert gas, and then the air inlet switch 6 and the connecting switch 8 are closed to keep the transition chamber 2 sealed for temporary storage of experimental materials. At the same time, when it is necessary to use the operating chamber 1 to perform experimental operations and convey inert gas to the operating chamber 1, the transition chamber 2 can still maintain a good inert gas environment. After the operating chamber 1 is filled with inert gas, the closed door 103 in the operating chamber 1 can be used to open the closed door 3, and the experimental materials in the transition chamber 2 can be taken out and placed in the operating chamber 1. If it is necessary to take out the experimental materials in the operating chamber 1, first place the experimental materials in the transition chamber 2 through the closed door 3, then close the closed door 103, and at the same time close the air inlet switch 6 and the connecting switch 8. At this time, the closed door 24 can be opened to take out the experimental materials, and the inert gas environment in the operating chamber 1 can be maintained as much as possible so as to continue the experiment.
