Description
Technical Field
[0001] This utility model belongs to the technical field of lithium metal production equipment, and in particular relates to a door device for the transition compartment of a lithium metal glove box. Background Technology
[0002] Lithium metal is a highly reactive metal, readily reacting with oxygen and water in the air to form oxides or hydroxides on its surface. This not only affects its purity but can also pose safety hazards. Therefore, in its production and further processing, to obtain lithium metal with lower impurity content and higher purity, casting is carried out in a glove box. The glove box provides an anhydrous and oxygen-free environment to ensure the safety and stability of the lithium metal. During the processing of lithium metal, the entry and exit of materials within the glove box are all completed inside its transition chamber. To prevent lithium metal from reacting with water vapor and oxygen, the air inside the transition chamber needs to be replaced with argon gas when materials enter and exit. Due to the frequent entry and exit of materials into the transition chamber, its sealing requirements are high. If the seal is not tight, it will not only increase the consumption of argon gas, affecting the production cost, but also may allow air to enter, thus affecting product quality.
[0003] The transition compartment's doors include a transition door connected to the glove box and an outer hatch connecting to the outside. Traditionally, the transition compartment uses a combination of counterweights and hydraulic latches to seal the transition door. However, due to the significant swaying of the transition compartment during operation, the hydraulic latches inside the transition door are prone to incomplete sealing due to the swaying, thus affecting its airtightness and consequently impacting the overall sealing performance of the equipment. Furthermore, if the hydraulic pressure of the hydraulic latches is too high, it can easily cause damage to the oil seals. This not only affects the sealing performance of the transition door but also easily leads to contamination of the glove box and the transition compartment, causing inconvenience for lithium metal processing. The frequent replacement of hydraulic latches after oil seal damage further increases the production cost of lithium metal processing. Traditionally, outer hatches are sealed using bolt clips. If the outer hatch is not properly sealed, bolts are often added to the outside to adjust the seal. However, due to the frequent entry and exit of the transition compartment, this sealing method not only greatly increases the labor intensity of disassembling the bolt clips when opening and closing the outer hatch, thus increasing the workload of the user, but also increases the time required to open and close the outer hatch, which in turn increases the time required for materials to enter and exit the transition compartment, affecting the overall processing efficiency.

[0020] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of a lithium metal glove box transition compartment door device.
[0021] like Figure 1-4 As shown, the door device of the transition compartment 3 of the lithium metal glove box 4 of this utility model includes a transition door 1 and an outer door 2, which are respectively located at both ends of the transition compartment 3. In this embodiment, the transition compartment 3 is located on the front side of the glove box 4, with a rear end opening corresponding to and communicating with the glove box 4, and a front end opening communicating with the outside. The transition door 1 is located at the rear end opening of the transition compartment 3, between the transition compartment 3 and the glove box 4. The transition compartment 3 is sealed to the glove box 4 through the transition door 1. The outer door 2 is located at the front end opening of the transition compartment 3, and the transition compartment 3 is sealed to the outside through the outer door 2.
[0022] The front opening of the transition compartment 3 is provided with a corresponding front door flange 31, which is connected to the outer door 2. The outer door 2 includes a sliding assembly, a first sealing body, and an outer door body 21. The outer door body 21 is located in front of the front door flange 31 and corresponds to it. A pair of corresponding sliding assemblies are provided on the upper and lower sides of the front end of the transition compartment 3. The upper and lower ends of the outer door body 21 are respectively connected to the corresponding sliding assemblies by corresponding guide blocks 22. The outer door body 21 is slidably connected to the two sliding assemblies. In this embodiment, two pairs of corresponding guide blocks 22 are provided on the upper and lower sides of the outer door body 21. The two pairs of guide blocks 22 are mirror images of each other along the centerline of the outer door body 21. Taking the two guide blocks 22 above the outer door body 21 as an example, the bottom ends of the two guide blocks 22 are fixedly connected to the left and right sides of the front sidewall of the outer door body 21, and their top ends are slidably connected to the sliding assembly above the outer door body 21. On the upper side of the transition compartment 3, a first driving device is provided above the sliding assembly, which is connected to the guide block 22 of the outer door 21. The sliding assembly and the first driving device are both fixedly connected to the outer wall of the transition compartment 3 through the support frame 7. The outer door 21 can move left and right along the sliding assembly on the front side of the transition compartment 3 under the power of the first driving device, thereby opening and closing the front opening of the transition compartment 3. During this process, the sliding assembly provides guidance, support and limiting function for the outer door 21. The front side of the front door flange 31 of the outer ring of the front opening of the transition compartment 3 is provided with a concave annular first sealing groove. The radial dimension of the first sealing groove is smaller than that of the outer door 21. The first sealing body is installed in the first sealing groove. When the outer door 2 is in the closed state, the first sealing body is located between the front door flange 31 and the outer door 21, filling the gap between the two, thereby sealing the front opening of the transition compartment 3.
[0023] Two sliding components are mirror images of each other along the centerline of the front opening of the transition compartment 3. Taking the upper sliding component as an example, it includes a sliding shaft 23, which is horizontally positioned above the transition compartment 3 and perpendicular to its axis. The upper end of the guide block 22 on the upper side of the outer door 2 is slidably connected to the upper end of the sliding shaft 23. When the outer door 2 is opened and closed, it slides left and right along the sliding shaft 23 under the action of the guide block 22. The sliding shaft 23 provides guidance for the outer door body 21. A pair of corresponding limit blocks 24 are provided at the left and right ends of the sliding shaft 23. Both limit blocks 24 are fixedly connected to the corresponding ends of the sliding shaft 23, which limit the sliding of the guide block 22 on the sliding shaft 23 to prevent it from falling off and causing danger. Below the sliding shaft 23, there is a guide rod 25 with a length corresponding to the front door flange 31 of the transition compartment 3. The top end of the guide rod 25 is fixedly connected to the bottom surface of the sliding shaft 23. A corresponding support frame 7 is provided on the rear side of the guide rod 25. The guide rod 25 is fixedly connected to the side wall of the transition chamber 3 via the corresponding support frame 7. It is positioned between the outer door body 21 and the sliding shaft 23, with its bottom surface higher than the top of the first sealing body. The bottom surface of the guide rod 25 has a groove 26 parallel to the sliding shaft 23, and the groove 26 corresponds to the side of the outer door body 21. In this embodiment, the side cross-section of the outer door body 21 is a V-shape with a thicker inner side and a thinner outer side. The groove 26 of the guide rod 25 is set to a corresponding V-shape. The outer door body 21 gradually... As it gradually moves to the front of the front door flange 31, its upper and lower ends are inserted into the corresponding sliding grooves 26, and the two are slidably connected. When the outer door body 21 moves to the front opening of the transition compartment 3, it stops moving forward under the obstruction of the left limit block 24 of the sliding shaft 23. At this time, the axial projections of the outer door body 21 and the front door flange 31 coincide, and the outer door 2 is in the closed state. The guide rod 25 provides guidance and support for the outer door body 21, and also provides axial limit for the outer door body 21.
[0024] Furthermore, the first sealing body includes a first sealing ring 5 correspondingly installed in the first sealing groove. The first sealing ring 5 is an annular inflatable sealing ring. A first through hole is provided on the side wall of the front door flange 31 above the transition chamber 3, and the front and rear ends of the first through hole are respectively connected to the rear side of the first sealing groove and the rear side of the front door flange 31. A first pipe 51 communicating with the first sealing ring 5 is provided in the first through hole. The first sealing ring 5 is connected to an external inflation pipe through the first pipe 51. A first pressure transmitter 53, a first valve 52, and a first pressure gauge 54 are installed on the first pipe 51. The first valve 52 is located at the other end of the first pipe 51 opposite to the first sealing ring 5, and it controls the gas flow in the first pipe 51. The force transmitter 53 and the first pressure gauge 54 are located between the first sealing ring 5 and the first valve 52. During operation, an external gas filling pipeline can inject inert gas into the first sealing ring 5 through the first pipeline 51. The first sealing ring 5 begins to expand under the filling of inert gas and gradually fills the gap between the outer door body 21 and the front door flange 31 to achieve a sealing effect. In this embodiment, argon gas is used as the filling inert gas. The first pressure gauge 54 can display the gas pressure in the first pipeline 51 in real time. The first pressure transmitter 53 is connected to the control system of the glove box 4, which can transmit the gas pressure value in the first pipeline 51 to the control system of the glove box 4 in real time so that the staff can monitor the gas condition in the first pipeline 51 in real time.
[0025] The first driving device includes a first hydraulic cylinder 27 and a first telescopic rod 28. The first hydraulic cylinder 27 is located above the sliding shaft 23 on the right side of the transition chamber 3, parallel to the sliding shaft 23. It is fixedly connected to the outer wall of the transition chamber 3 through a corresponding support frame 7. The first telescopic rod 28 is located at its left top end and is also parallel to the sliding shaft 23. Its right end is connected to the first hydraulic cylinder 27, and its left end is connected to the guide block 22 on the left side of the outer door 21 through a corresponding connecting block. The first telescopic rod 28 can extend and retract left and right under the action of the first hydraulic cylinder 27, thereby driving the outer door 21 to slide left and right on the sliding shaft 23 through the guide block 22.
[0026] The rear end of the transition chamber 3 extends into the glove box 4, and its rear opening is provided with a corresponding rear door flange 32. The transition chamber 32 is connected to the transition door 1. The transition door 1 includes a guide plate 12, a second sealing body, and an inner door body 11. The inner door body 11 corresponds to the rear door flange 32 and is located on the rear side of the rear door flange 32. The guide plates 12 are vertically arranged in pairs on the left and right sides of the rear end of the rear door flange 32. Each guide plate 12 has a guide groove 13 corresponding to the inner door body 11. The guide groove 13 is located on the side of the guide plate 12 corresponding to the inner door body 11. The left and right sides of the inner door body 11 are respectively inserted into the guide grooves 13 on their left and right sides, and the two are slidably connected. The upper part of the inner door body 11 is provided with... There is a corresponding second driving device, which can slide up and down along the guide groove 13 under the action of the second driving device, thereby realizing the opening and closing of the transition door 1. The guide groove 13 provides a guiding function. The rear side of the rear door flange 32 on the outer ring of the rear opening of the transition chamber 3 is provided with a concave annular second sealing groove. The radial dimension of the second sealing groove is smaller than that of the inner door body 11. The second sealing body is installed in the second sealing groove. When the inner door body 11 moves to the bottom of the guide groove 13, it coincides with the axial projection of the rear door flange 32. At this time, the transition door 1 is in the closed state. The second sealing body is located between the rear door flange 32 and the inner door body 11, filling the gap between the two, thereby playing the role of sealing the rear opening of the transition chamber 3.
[0027] The second sealing body includes a second sealing ring 6 installed in the second sealing groove. The second sealing ring 6 is an annular inflatable sealing ring. A second through hole is provided on the side wall of the rear door flange 32 above the transition chamber 3. The front and rear ends of the second through hole are respectively connected to the front side of the second sealing groove and the front side of the rear door flange 32. A second pipe 61 connected to the second sealing ring 6 is provided in the second through hole. The second sealing ring 6 is connected to an external inflation pipe through the second pipe 61. A second pressure transmitter 63, a second pressure gauge 64, and a second valve 62 are installed on the second pipe 61. The second valve 62 is located at the other end of the second pipe 61 opposite to the second sealing ring 6, and it controls the gas flow in the second pipe 61. The transmitter 63 and the second pressure gauge 64 are located between the second sealing ring 6 and the second valve 62. During operation, an external gas filling pipeline can inject inert gas into the second sealing ring 6 through the second pipeline 61. The second sealing ring 6 begins to expand under the filling of inert gas and gradually fills the gap between the inner door body 11 and the rear door flange 32 to achieve a sealing effect. In this embodiment, argon is used as the filling inert gas. The second pressure gauge 64 can display the gas pressure in the second pipeline 61 in real time. The second pressure transmitter 63 is connected to the control system of the glove box 4, which can transmit the gas pressure value in the second pipeline 61 to the control system of the glove box 4 in real time so that the staff can monitor the gas status in the second pipeline 61 in real time.
[0028] The second driving device includes a second hydraulic cylinder 14 and a second telescopic rod 15. The second hydraulic cylinder 14 is fixedly installed on the top wall of the glove box 4 above the inner door body 11. The second telescopic rod 15 is located below it. The top end of the second telescopic rod 15 is connected to the bottom of the second hydraulic cylinder 14, and its bottom end passes through the top wall of the glove box 4 and is connected to the top end of the inner door body 11. It is slidably sealed to the side wall of the glove box 4. The second telescopic rod 15 can extend and retract up and down under the action of the second hydraulic cylinder 14, thereby driving the inner door body 11 to slide up and down along the guide groove 13.
[0029] Under normal conditions, both the transition door 1 and the outer hatch 2 are closed, and they cannot be opened simultaneously during use. When materials need to be fed into the glove box 4 through the transition chamber 3, firstly, the gas in the first sealing ring 5 is discharged through the first pipeline 51. Then, the outer door 21 is slid to the right side of the front door flange 31 by the first drive device. At this time, the outer hatch 2 is in the open state, and materials can be placed into the inner cavity of the transition chamber 3. Next, after the outer door 21 is slid to the front side of the front door flange 31 by the first drive device, argon gas is injected into the first sealing ring 5 through the first pipeline 51 until it fills the gap between the outer door 21 and the front door flange 31. At this time, the outer hatch 2 is in the sealed closed state. Thus, one opening and closing of the outer hatch 2 is completed. At this time, the air exchange and filtration system of the transition chamber 3 can be used to replace the air inside with argon gas and filter out the moisture in the gas inside, making its inner cavity as dry as possible. After filtration, the transition door 1 can be opened to transfer the material into the glove box 4. Specifically: First, the gas in the second sealing ring 6 is discharged through the second pipeline 61. Then, the inner door 11 is slid to the upper side of the rear door flange 32 through the second drive device. At this time, the transition door 1 is in the open state, and the material can be transferred into the glove box 4. Next, after the inner door 11 is slid to the rear side of the rear door flange 32 through the second drive device, argon gas is injected into the second sealing ring 6 through the second pipeline 61 until it fills the gap between the inner door 11 and the rear door flange 32. At this time, the transition door 1 returns to the sealed closed state. One opening and closing of the transition door 1 is completed, and one material input of the glove box 4 is completed. When it is necessary to transfer material from the glove box 4 to the outside, the above operation is repeated in reverse: first, open the transition door 1 to transfer the material into the transition chamber 3, then close the transition door 1, open the outer door 2, take out the material, and then close the outer door 2.
[0030] The outer hatch 2 of this utility model, which is a door device for a lithium metal glove box 4 and a transition chamber 3, adopts a combination of a first driving device and a sliding device. Its structure is simpler and easier to operate, reducing the labor intensity and time consumption of users during operation, and saving more time and effort. The transition door 1 adopts a combination of a second driving device and a guide plate 12, which reduces the impact of the swing of the transition chamber 3 on it, reduces the probability of damage to the second driving device, and thus reduces the probability of contamination of the glove box 4 and the transition chamber 3. Moreover, both the first sealing ring 5 and the second sealing ring 6 are inflatable sealing rings, which improves the airtightness of the outer hatch 2 and the transition door 1, reduces the consumption of argon gas, and reduces the overall production cost. Furthermore, the use of the door device for the transition chamber 3 of this utility model reduces the time required for materials to enter and exit the transition chamber 3, making the overall processing efficiency faster.
