Description

Technical Field

[0001] This utility model relates to the technical field of feeding devices, specifically a sealed automatic feeding device. Background Technology

[0002] The feeding device, also known as a glove box, is a laboratory piece of equipment primarily used for various experimental operations in an ultrapure environment free of water, oxygen, and dust. It provides a stable experimental environment by filling the chamber with high-purity inert gas and circulating and filtering out reactive substances such as nitrogen. A glove box is typically a fully enclosed cavity that completely isolates the internal environment from the external environment. One side of the chamber is equipped with a viewing window and operating gloves, allowing operators to handle the products inside the chamber. When handling toxic or hazardous materials, the glove box protects both the operator and the environment.

[0003] Patent document CN218226755U discloses a glove box, which includes: a flexible box body with an inner side forming an operating space; a gas frame connected to the flexible box body; wherein the flexible box body and the gas frame are formed of a flexible material, and in the uninflated state, the flexible material is foldable or compressible; the gas frame expands the flexible box body when inflated. This utility model uses a gas frame to support the flexible box body. The fully flexible design avoids damage to the glove box caused by rigid support components puncturing the flexible material box body, and also solves the problem of rigid support components being difficult to carry.

[0004] However, the glove box in the aforementioned published literature is mainly designed to solve the problem that rigid supports are not easy to carry, making it inconvenient to unload materials and eliminating the need for continuous manual feeding. The original device uses a glove box installed at the reactor mouth, filled with nitrogen for protection, and manual batch feeding is used. This operation method has feeding safety risks, as operators at the reactor mouth are prone to injury when feeding materials during abnormal reactions, and there is also the risk of human error (overfeeding or underfeeding).

[0005] In view of this, it is necessary to develop an automatic feeding mechanism to facilitate the feeding of materials without the need for manual continuous feeding. Utility Model Content

[0006] The purpose of this utility model is to provide a sealing automatic feeding device to solve the technical problem mentioned in the background art of enabling the sealing feeding device to have an automatic feeding function.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a sealed automatic feeding device, comprising: a glove box, wherein the inner wall of the glove box is provided with an automatic feeding mechanism, the automatic feeding mechanism being used to facilitate feeding of materials without the need for manual continuous feeding;

[0008] The automatic feeding mechanism includes a hinge disposed on the outer wall of the glove box. A sealing plate is installed on the outer wall of the hinge. A pneumatic quantitative rotary valve is installed at the bottom of the glove box. A glove body is embedded in the outer wall of the glove box. A two-position five-way manual valve is installed on the outer wall of the pneumatic quantitative rotary valve. A nitrogen pipe is installed on the outer wall of the glove box. An exhaust valve is installed on the outer wall of the glove box. A stainless steel storage funnel is installed on the inner wall of the glove box, and the stainless steel storage funnel is located on top of the pneumatic quantitative rotary valve.

[0009] Preferably, the outer wall of the glove box is provided with a gas detection mechanism, which is used to conveniently control the amount of nitrogen entering the glove box.

[0010] Preferably, the gas detection mechanism includes a control terminal, which is disposed on the outer wall of the glove box. An indicator light and a control button are installed on the outer wall of the control terminal.

[0011] Preferably, the inner wall of the glove box is provided with an air inlet, and an electromagnetic valve is installed on the inner wall of the air inlet.

[0012] Preferably, an air volume box is installed at the bottom of the glove box.

[0013] Preferably, a positioning slide rod is installed on the inner wall of the gas volume box, a trigger plate is installed around the outer wall of the positioning slide rod, a trigger block is installed on the outer wall of the trigger plate, and a trigger button is installed on the inner wall of the gas volume box.

[0014] Preferably, a sleeve is installed on the inner wall of the gas volume box, a sleeve rod is installed on the inner wall of the sleeve, a return spring is installed around the outer wall of the sleeve rod, and one end of the sleeve rod extends to the outer wall of the trigger plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model features an automatic feeding mechanism, facilitating material feeding without requiring continuous manual feeding. Existing devices use a glove box installed at the reactor inlet, filled with nitrogen for protection. Material is manually added in batches and quantities, posing safety risks. Operators at the reactor in case of reaction abnormalities are easily injured during feeding, and there is also the risk of human error (overfeeding or underfeeding). Therefore, this design needs improvement. During production, the sealing plate is opened via a hinge, opening the glove box's feed window. Packaged materials are placed inside the glove box. The feed window is then closed, connecting the nitrogen pipe to an external nitrogen supply device, allowing nitrogen to fill the glove box. Once the glove box is full, the materials are unpacked inside and placed into a stainless steel storage funnel. Material feeding is completed by pulling a two-position five-way manual valve to control a pneumatic quantitative star-shaped feed valve. The nitrogen in the glove box is also released through an exhaust valve connected to the outside.

[0017] 2. This utility model, by installing a gas detection mechanism, facilitates the control of the amount of nitrogen entering the glove box. Since the glove box needs to be filled with nitrogen, workers cannot know when the glove box is full, leading to situations where too much or too little nitrogen is injected. Therefore, this needs to be improved. When injecting nitrogen, the solenoid valve operates, allowing the inlet to flow. Nitrogen gradually flows into the gas tank, pushing the trigger plate to move on the positioning slide rod, and the sleeve rod moves within the sleeve. The return spring is compressed. When the trigger block touches the trigger button, the indicator light illuminates, indicating that the internal nitrogen is full and no further injection is needed. This avoids situations where insufficient nitrogen injection affects the normal operation of the glove box. Attached Figure Description

[0026] Please see Figure 1 and Figure 2An automatic sealing feeding device includes: a glove box 1, with an automatic feeding mechanism on the inner wall of the glove box 1 for convenient material feeding without manual continuous feeding. The automatic feeding mechanism includes a hinge 2, which is disposed on the outer wall of the glove box 1. A sealing plate 3 is installed on the outer wall of the hinge 2. A pneumatic quantitative star-shaped feeding valve 5 is installed at the bottom of the glove box 1. A glove body 4 is embedded in the outer wall of the glove box 1. A two-position five-way manual valve 6 is installed on the outer wall of the pneumatic quantitative star-shaped feeding valve 5. A nitrogen pipe 7 and an exhaust valve 8 are installed on the outer wall of the glove box 1. A stainless steel storage funnel 9 is installed on the inner wall of the glove box 1, and the stainless steel storage funnel 9 is located on top of the pneumatic quantitative star-shaped feeding valve 5. The original device used a glove box 1 installed at the mouth of a reaction vessel, with the glove box 1 filled with nitrogen for protection. The feeding process currently involves manual batching and quantitative addition of materials. This method poses a safety risk, as operators are prone to injury when the reaction is abnormal at the vessel opening and during material feeding. Furthermore, human error (overfeeding or underfeeding) is a concern. Therefore, improvements are needed. During production, the sealing plate 3 is opened via hinge 2, opening the feed window of glove box 1. Packaged materials are placed into the glove body 4, and the feed window of glove box 1 is closed, connecting the nitrogen pipe 7 to an external nitrogen supply device. Nitrogen is then introduced into glove box 1. Once glove box 1 is full of nitrogen, the materials are unpacked inside glove box 1 and placed into the stainless steel storage funnel 9. Material addition is completed by pulling the two-position five-way manual valve 6 to control the pneumatic quantitative star-shaped feed valve 5. The nitrogen in glove box 1 is then released through the exhaust valve 8, connecting it to the outside environment.

[0027] Please see Figure 3 and Figure 4The outer wall of glove box 1 is equipped with a gas detection mechanism for convenient control of the amount of nitrogen entering glove box 1. The gas detection mechanism includes a control terminal 10, which is located on the outer wall of glove box 1. An indicator light 11 and a control button 12 are installed on the outer wall of control terminal 10. The inner wall of glove box 1 is equipped with an air inlet 13, and a solenoid valve 14 is installed on the inner wall of air inlet 13. A gas volume box 15 is installed at the bottom of glove box 1. A positioning slide rod 16 is installed on the inner wall of gas volume box 15. A trigger plate 17 is installed around the outer wall of positioning slide rod 16. A trigger block 19 is installed on the outer wall of trigger plate 17. A trigger button 18 is installed on the inner wall of gas volume box 15. A sleeve 20 is installed on the inner wall of gas volume box 15, and a sleeve rod 21 is installed on the inner wall of sleeve 20. A return spring 22 is installed around the outer wall of the sleeve 21, and one end of the sleeve 21 extends to the outer wall of the trigger plate 17. Since the glove box 1 needs to be filled with nitrogen, the operator cannot know when the nitrogen in the glove box 1 is full, which may result in overfilling or underfilling. Therefore, this needs to be improved. When filling with nitrogen, the solenoid valve 14 works to allow the air inlet 13 to flow, and the nitrogen in the glove box 1 gradually flows into the gas volume box 15. The nitrogen pushes the trigger plate 17 to move on the positioning slide rod 16, and the sleeve 21 moves in the sleeve 20. The return spring 22 is compressed. When the trigger block 19 touches the trigger button 18, the indicator light 11 lights up, indicating that the internal nitrogen is full and no further filling is needed. This avoids the situation where the nitrogen is underfilled and affects the normal operation of the glove box 1.

[0028] Working principle: The original device used a glove box 1 installed at the reactor inlet, filled with nitrogen for protection. Material was manually added in batches and quantities. This method posed safety risks, as operators at the reactor inlet were prone to injury during material feeding in case of reaction abnormalities. Furthermore, human error (over- or under-feeding) was possible. Therefore, an improvement was needed. During production, the sealing plate 3 was opened via hinge 2, opening the feed window of glove box 1. Packaged materials were placed into the glove body 4. The feed window of glove box 1 was then closed, connecting the nitrogen pipe 7 to an external nitrogen supply device, thus filling glove box 1 with nitrogen. Once glove box 1 was full of nitrogen, the material was unpacked inside glove box 1 and placed into the stainless steel storage funnel 9. The pneumatic quantitative star-shaped feed valve 5 was controlled by pulling a two-position five-way manual valve 6. When materials are added, and the nitrogen in glove box 1 is connected to the outside through exhaust valve 8, the nitrogen in glove box 1 is discharged. Since glove box 1 needs to be filled with nitrogen, the staff cannot know when the nitrogen in glove box 1 is full, which may lead to overfilling or underfilling. Therefore, this needs to be improved. When filling with nitrogen, the solenoid valve 14 works to open the air inlet 13, and the nitrogen in glove box 1 is gradually filled into the gas volume box 15. The nitrogen pushes the trigger plate 17 to move on the positioning slide rod 16, and the sleeve rod 21 moves in the sleeve 20. The return spring 22 is compressed. When the trigger block 19 touches the trigger button 18, the indicator light 11 lights up, indicating that the internal nitrogen is full and no further filling is needed. This avoids the situation where the nitrogen is underfilled and affects the normal operation of glove box 1.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
