Description

Technical Field

[0001] This utility model belongs to the field of glove box structure design technology, specifically relating to a glove box filter and the glove box thereof. Background Technology

[0002] A vacuum glove box is a laboratory device that fills the chamber with high-purity inert gas and circulates it to filter out active substances. It is also called a glove box or inert gas protection chamber. It is primarily used for the removal of O2, H2O, and organic gases. It is widely used in ultra-pure environments that are anhydrous, oxygen-free, and dust-free, such as those used in lithium-ion batteries and materials, semiconductors, supercapacitors, special lamps, laser welding, and brazing. Furthermore, the glove box is an ideal device for scientific experiments in universities, research institutions, and corporate laboratories, and is widely used in biochemistry, metallurgy, electronics, chemical engineering, geology, mining, and pharmaceutical industries.

[0003] When using a glove box for certain chemical experiments or production, if a large amount of organic solvent is used inside the glove box, organic solvent gas will evaporate inside the glove box. If the organic solvent gas is not dealt with in time, it will not only damage the water and oxygen probe and vacuum pump, but may even leak from the glove box into the room.

[0004] Currently, existing glove boxes mainly use activated carbon mesh to adsorb organic solvent gases. Once the mesh is saturated with organic solvent, the activated carbon loses its adsorption efficiency, requiring timely replacement. However, replacing activated carbon in existing technologies is inconvenient and cannot meet the needs of glove box operation. Our company's R&D team has designed a glove box filter to solve these technical problems. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1:

[0027] Please see Figures 1 to 4As shown, this utility model embodiment provides a glove box filter, specifically including a stainless steel shell 1, one end of which is fixedly connected to a connecting pipe 2, which is connected to an external circulation pump for air suction. Inside the shell 1, near the connecting pipe 2, there is a filter element 3, which can filter activated carbon dust and the like. Inside the shell 1, there is a replacement mechanism 4.

[0028] Please see Figure 2 and Figure 3 As shown, the replacement mechanism 4 includes sliding grooves 41 formed at the top and bottom of the inner shell 1. Springs 42 are fixedly connected to the side of each sliding groove 41 near the connecting pipe 2, and first sliders 43 are fixedly connected to the ends of the springs 42. An activated carbon mesh 44 is provided on the side of the outer shell 1 away from the connecting pipe 2. Connecting blocks 45 are fixedly connected to the top and bottom of the activated carbon mesh 44 near the connecting pipe 2, and wedge-shaped blocks 46 are fixedly connected to the ends of the connecting blocks 45. A pull ball 47 is fixedly connected to the side of the activated carbon mesh 44 away from the outer shell 1. A stop block 6 is fixedly connected to the side of each sliding groove 41 that is far apart from the outer shell 1. The side of the stop block 6 near the activated carbon mesh 44 is in contact with the first slider 43. The design of the stop block 6 allows the activated carbon mesh 44 to be disassembled quickly without excessive inward pressure.

[0029] Please see Figure 2 and Figure 3 As shown, slide rails 7 are provided at both the top and bottom of the outer casing 1 on the side away from the connecting pipe 2. Second sliders 8 are fixedly connected to both the top and bottom of the activated carbon mesh 44, and are located within the slide rails 7. The design of the slide rails 7 and second sliders 8 ensures that when the horizontal end of the wedge block 46 is precisely aligned with the end of the first slider 43, the second slider 8 slides to the innermost side of the slide rail 7. This indicates that the horizontal end of the wedge block 46 is precisely aligned with the end of the first slider 43, allowing the activated carbon mesh 44 to be pulled outwards directly. This avoids excessive compression of the wedge block 46, which could cause it to move to the side of the first slider 43 closer to the spring 42. Positioning holes 9 are provided on the sides of the two wedge blocks 46 that are far apart. L-shaped positioning rods 10 are fixedly connected to both the top and bottom of the outer casing 1. The design of the positioning holes 9 and L-shaped positioning rods 10 achieves a positioning effect, facilitating installation.

[0030] In this embodiment, two wedge-shaped blocks 46 are pressed tightly against the inner wall of the outer shell 1, and then pressed inward with force. Under the action of the inclined surface of the wedge-shaped blocks 46, the two wedge-shaped blocks 46 move closer to each other, the connecting block 45 bends and deforms, and then the wedge-shaped blocks 46 enter the outer shell 1 and remain tightly against the inner wall of the outer shell 1. Then, the activated carbon mesh 44 is placed at the port of the outer shell 1. When the wedge-shaped blocks 46 contact the first slider 43, the wedge-shaped blocks 46 press against it, and the spring 42 is compressed. Then, when the wedge-shaped blocks 46 reach the slide groove 41, the connecting block 45 returns to its original shape, and the wedge-shaped blocks 46 are inserted into the slide groove 41. The tension of the spring 42 causes the first slider 43 to press and fix the wedge-shaped blocks 46. At this time, the activated carbon mesh 44 is installed and fixed. When disassembling, the activated carbon mesh 44 is pressed inward again. The activated carbon mesh 44 is pushed inward by the wedge block 46 driven by the connecting block 45. The wedge block 46 continues to push the first slider 43. When the spring 42 can no longer be compressed, the position of the first slider 43 is fixed and continues to push the activated carbon mesh 44. Under the action of the inclined surface of the wedge block 46, the connecting block 45 deforms again. Then the horizontal end of the wedge block 46 fits with the end of the first slider 43. At this time, under the action of the restoring force of the connecting block 45, a compression is formed between the wedge block 46 and the first slider 43. Then the activated carbon mesh 44 is released. Under the action of the spring 42, the activated carbon mesh 44 pops outward. Then the horizontal end of the wedge block 46 is flush with the inner side wall of the outer shell 1. At this time, the activated carbon mesh 44 can be disassembled by pulling the ball 47 outward.

[0031] In this embodiment, pressing the activated carbon mesh 44 causes the connecting block 45 to deform, and the wedge block 46 is inserted into the sliding groove 41, thereby achieving the installation and fixation of the activated carbon mesh 44. When the activated carbon mesh 44 is saturated with organic solvent gas, pressing the activated carbon mesh 44 causes the connecting block 45 to deform again, and the end of the wedge block 46 is tightly attached to the end of the first slider 43. Then, the activated carbon mesh 44 is pulled outward, realizing the quick replacement of the activated carbon mesh 44. This can avoid damage to the water and oxygen probe and vacuum pump by organic solvent gas and prevent odor leakage.

[0032] Please see Figure 4As shown, in this embodiment, the outer shell 1 has a circulation mechanism 5 inside. The circulation mechanism 5 includes a connecting rod 51 fixedly connected to the activated carbon mesh 44 on the side away from the pull ball 47. A frame 52 is fixedly connected inside the outer shell 1. A connecting plate 53 is fixedly connected to the end of the connecting rod 51. An activated carbon frame 54 is provided inside the frame 52, and the activated carbon frame 54 is fixedly connected to the connecting plate 53. Guide plates 55 are fixedly connected to the top and bottom of the outer shell 1. A set of double-sided tape 11 is fixedly connected to the top of the activated carbon frame 54. Oil paper 12 is provided on both sides of the top of the double-sided tape 11, and the oil paper 12 is fixedly connected to the top of the activated carbon frame 54. The design of the double-sided tape 11 can adsorb dust and impurities in the gas. The design of the oil paper 12 can prevent the double-sided tape 11 from sticking to the activated carbon frame 54 under the blowing of wind. The distance between adjacent double-sided tapes 11 is greater than the length of the double-sided tape 11, and the distance between the double-sided tape 11 and the inner rear side of the activated carbon frame 54 is greater than the length of the double-sided tape 11, so as to prevent two adjacent double-sided tapes 11 from sticking together under the influence of wind.

[0033] During operation, the connecting pipe 2 connects to the circulation pump for suction, and the organic solvent gas enters the outer casing 1. Under the action of the guide plate 55, the guide plate 55 is guided into the frame 52, and then contacts the activated carbon frame 54 for secondary purification. After that, it is blown towards the filter element 3, which is conducive to the secondary treatment of organic solvent gas, avoids the presence of any untreated organic solvent gas, and ensures that the organic solvent gas is fully purified.

[0034] Example 2:

[0035] This utility model embodiment provides a glove box, including a glove box body, a transition compartment fixedly connected to one side of the glove box body, and a glove box filter, which is fixedly installed inside the glove box body. Typically, the filter is installed at the air inlet and air outlet of the air inlet and outlet ducts.
