A new glove box filter device

Abstract

The present invention provides a novel glove box filter device, comprising a glove box body, a filtering mechanism mounted on the glove box body, a supporting mechanism mounted on the glove box body, a collection mechanism mounted on the glove box body, and a sealing mechanism mounted on the collection mechanism. In this embodiment, after dust and pollutants are filtered through the second and first filter screens, the top opening of the collection tube is larger than the opening of the guide tube, allowing for better collection and processing of the dust and pollutants. Because a fixed plate contacts the bottom end of the collection tube, the elastic force of a third spring causes the fixed plate to contact the top end of the collection tube with the guide tube, preventing dust and pollutants from falling. This makes use more convenient. When the collection tube needs to be removed for processing, the collection tube can be removed by means of a handle.

Description

Technical Field

[0001] The invention belongs to the technical field of vacuum glove box filter structure design, and particularly relates to a novel glove box filter device. Background Art

[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 known as a glove box, inert gas protection box, or sealed box. It primarily removes O2, H2O, and organic gases. It is widely used in ultra-pure environments without water, oxygen, or dust, such as for lithium-ion batteries and materials, semiconductors, supercapacitors, specialty lamps, laser welding, and brazing.

[0003] Currently, filters are installed on both the air inlet and exhaust ducts of a glove box. These filters are crucial components for ensuring the proper functioning of the glove box's purification and filtration system. These filters are typically integrated. While stable, these integrated structures make it difficult to replace the filter screens during use. Furthermore, since the filters are installed in both the air inlet and exhaust ducts, filtered pollutants can fall into these ducts, necessitating regular cleaning of the ducts.

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments 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.

[0031] See also Figures 1 to 8 As shown, an embodiment of the present invention provides a novel glove box filter device, specifically comprising a glove box body 1, a filtering mechanism 2 mounted on both the air inlet and exhaust ducts of the glove box body 1, a supporting mechanism 3 and a collecting mechanism 4 mounted on the glove box body 1, and a sealing mechanism 5 mounted on the collecting mechanism 4. The following provides a detailed technical explanation of the specific structures and functions of the filtering mechanism 2, supporting mechanism 3, collecting mechanism 4, and sealing mechanism 5.

[0032] See also Figure 1 、 Figure 3 、 Figure 4 and Figure 5As shown, in this embodiment, the filtering mechanism 2 specifically includes a first filter 203, which is fixedly connected to the glove box body 1. The first filter 203 is fixedly connected to the first filter 203, which is fixedly connected to the mounting rod 201. The mounting rod 201 is fixedly connected to a rotating rod 205. A placement plate 204 is rotatably connected to the rotating rod 205. The placement plate 204 is provided with a first sliding groove 211. The placement plate 204 is slidably connected to a clamping plate 207 located within the first sliding groove 211. The side wall of the clamping plate 207 is fixedly connected to a limit rod 209, which is sleeved with a first spring 210. The placement plate 204 is provided with a placement frame 202, the bottom end of which is fixedly connected to the second filter 206. The bottom end of the placement frame 202 is provided with a clamping groove 208, and the top end of the clamping plate 207 engages with the clamping groove 208. The aperture of the second filter screen 206 is smaller than that of the first filter screen 203. The length of the placement plate 204 is greater than the diameter of the mounting rod 201, and the top of the placement plate 204 extends beyond the top of the mounting rod 201. A second spring 301 is fixedly connected to the first filter screen 203. The top ends of the two second springs 301 are fixedly connected to support plates 302. The bottom ends of the two support plates 302 contact the bottom end of the second filter screen 206.

[0033] In this specific embodiment, when installing, the end of the card plate 207 can be pressed by hand. Since a card slot 208 is provided at the bottom end of the placement frame 202, the top of the card plate 207 is inserted into the card slot 208, and the card plate 207 is released by hand. Under the elastic force of the first spring 210, the card plate 207 will engage with the card slot 208. When the second filter screen 206 is damaged, the card plate 207 can be pressed by hand to quickly replace the second filter screen 206, which is more convenient to use. In this embodiment, a second filter 206 is fixedly connected to the bottom end of the placement frame 202. Since the mesh gaps of the second filter 206 are smaller than the mesh gaps of the first filter 203, dust and pollutants can be filtered out through the second filter 206. Since two second springs 301 are fixedly connected to the first filter 203, the tops of the two second springs 301 are fixedly connected to a support plate 302. The support plate 302 can ensure the stability of the placement of the placement frame 202. Since the placement plate 204 is rotatably connected to the rotating rod 205, one end of the placement frame 202 can be pressed by hand. When the placement frame 202 is pressed, the second spring 301 will expand and contract, and the support plate 302 will always be in conflict with the bottom end of the placement frame 202 to ensure the stability of the placement frame 202.

[0034] See also Figure 1 、 Figure 2 、 Figure 6 and Figure 8As shown, the collection mechanism 4 specifically includes a guide tube 401, which is fixedly connected to the bottom end of the glove box body 1. A collection tube 402 is slidably connected to the guide tube 401. The cross-section of the guide tube 401 is an isosceles trapezoidal structure. The top opening of the collection tube 402 is larger than the bottom opening of the guide tube 401. A handle 403 is fixedly connected to the collection tube 402. A first slide bar 405 is slidably connected to the bottom end of the guide tube 401. The top end of the first slide bar 405 is fixedly connected to a fixing plate 404. A third spring 406 is sleeved on the first slide bar 405, and the top end of the fixing plate 404 contacts the bottom end of the collection tube 402.

[0035] In this specific embodiment, after the debris and dust are filtered through the second filter screen 206 and the first filter screen 203, since the bottom end of the glove box body 1 is fixedly connected to the guide tube 401, and the collection tube 402 is placed on the guide tube 401, the top opening of the collection tube 402 is larger than the opening of the guide tube 401, the dust and pollutants can be better collected and processed. Since the bottom end of the guide tube 401 is slidably connected to the first sliding rod 405, the top end of the first sliding rod 405 is fixedly connected to the fixing plate 404, and the first sliding rod 405 is sleeved with a third spring 406. The top end of the fixing plate 404 conflicts with the bottom end of the collection tube 402. Under the elastic force of the third spring 406, the fixing plate 404 will make the top end of the collection tube 402 conflict with the guide tube 401 to prevent dust and pollutants from falling. When it is necessary to remove the collection tube 402 to process the dust and pollutants, the collection tube 402 can be taken out through the handle 403, which is more convenient to use.

[0036] See also Figure 6 and Figure 7 As shown, the sealing mechanism 5 specifically includes a second slide groove 503, a second slide groove 503 is opened on the guide tube 401, a second slide rod 504 located in the second slide groove 503 is slidably connected to the guide tube 401, a fourth spring 505 is sleeved on the second slide rod 504, the top end of the second slide rod 504 is fixedly connected to the connecting rod 502, the side wall of the connecting rod 502 is fixedly connected to the baffle 501, and the bottom end of the second slide rod 504 is in conflict with the top end of the collecting tube 402. Among them, the cross-section of the baffle 501 is an isosceles trapezoidal structure, the cross-section of the second slide bar 504 is a "T"-shaped structure, and the baffle 501 is slidably connected to the guide tube 401. Since the bottom end of the second slide bar 504 conflicts with the top end of the collection tube 402, when the collection tube 402 is taken out to process dust and pollutants, the bottom end of the second slide bar 504 will be separated from the top end of the collection tube 402. At this time, under the elastic force of the fourth spring 505, the baffle 501 will slide downward. Since the cross-section of the baffle 501 is an isosceles trapezoidal structure, the baffle 501 will block the opening of the guide tube 401, which can prevent the remaining dust and pollutants from falling.
