Description

Technical Field

[0001] This invention belongs to the field of glove box structural design technology, specifically relating to an automatic moisture removal device for the transition compartment of a vacuum glove box. 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, inert gas protection box, or sealed box. 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.

[0003] In existing technology, when placing items into a vacuum glove box, the outer door of the transition chamber must first be opened, and then the gas inside the transition chamber must be expelled and replaced with inert gas before the inner door can be opened to retrieve the items using gloves. However, if the surface of the items contains moisture, directly placing them into the glove box will disrupt the internal environment and affect the experiment. Therefore, an automatic moisture removal device for the transition chamber of the vacuum glove box is needed to solve the above-mentioned technical problem. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide an automatic moisture removal device for the transition chamber of a vacuum glove box, thereby solving the above-mentioned technical problems.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An automatic dehumidification device for a vacuum glove box transition compartment includes a transition compartment body, a sealing door on the side of the transition compartment body, and a dehumidification mechanism inside the transition compartment body.

[0007] The dewatering mechanism includes an air inlet pipe fixedly connected to the top of the transition chamber body, a cylinder fixedly connected to the bottom end of the air inlet pipe, a heating grid fixedly connected inside the cylinder, a rotating shaft rotatably connected to the bottom end of the cylinder, a set of fan blades fixedly connected to the top end of the rotating shaft, an air storage plate fixedly connected to the bottom end of the rotating shaft, a rear plate fixedly connected to the rear side inside the transition chamber body, and an acoustic sensor fixedly connected to the front side of the bottom end of the rear plate.

[0008] As a preferred embodiment, the rotating shaft has a T-shaped hole inside, and the air storage plate has an L-shaped hole inside, with the T-shaped hole and the L-shaped hole connected.

[0009] As a preferred embodiment, the bottom end of the L-shaped hole is provided with a set of air outlet holes.

[0010] As a preferred embodiment, the transition chamber body is provided with a sealing mechanism. The sealing mechanism includes a connecting pipe fixedly connected to the bottom end of the air outlet. A sealing plate is rotatably connected inside the connecting pipe. A limiting block is provided on the top of the sealing plate near the air inlet pipe, and the limiting block is fixedly connected to the inner side wall of the connecting pipe.

[0011] As a preferred embodiment, the bottom end of the sealing plate is provided with a stop block on the side away from the air intake pipe, and the stop block is fixedly connected to the inner wall of the connecting pipe.

[0012] As a preferred embodiment, a gravity block is fixedly connected to the side of the sealing plate near the abutment block, and a wind guide plate is fixedly connected to the side of the connecting pipe away from the limiting block.

[0013] As a preferred embodiment, a straight rod is fixedly connected to the bottom of the interior of the transition chamber body, a placement platform is fixedly connected to the top of the straight rod, a number of fixed balls are fixedly connected to the top of the placement platform, and a number of ventilation openings are provided at the top of the placement platform.

[0014] As a preferred embodiment, a mounting block is fixedly connected to the side of the transition chamber body away from the sealing door, and screw holes are fixedly connected to the four corners of the mounting block.

[0015] As a preferred embodiment, an activated carbon mesh is fixedly connected inside the cylinder, and the activated carbon mesh is located on top of the heating mesh.

[0016] As a preferred embodiment, a filter screen is fixedly connected inside the air intake pipe, and the filter screen is located on top of the activated carbon mesh.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] (1) The present invention emits sound waves through a sound wave sensor to sense whether there is moisture on the surface of the item. If there is moisture, the heating grid is controlled to heat, and an external air source starts to input gas into the air inlet pipe. The heating grid heats the gas, and the hot gas is sprayed out through the air outlet. The gas drives the rotating shaft to rotate, and the rotating shaft drives the air storage plate to rotate, which is conducive to the rapid spraying of hot gas onto the surface of the item, improving the speed and efficiency of water removal, and realizing the automatic water removal function, avoiding the impact of moisture on the internal environment of the vacuum glove box.

[0019] (2) Under the action of the air guide plate, the hot air blows the sealing plate to rotate counterclockwise and the sealing plate will not be in a vertical state. After the water removal is completed, the sealing plate rotates clockwise under the action of the gravity block, and under the action of the limit block and the stop block, the sealing plate is in a horizontal state. At this time, the connecting pipe will be sealed to prevent the inert gas that is subsequently filled into the connecting pipe from entering the connecting pipe. Attached Figure Description

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figures 1 to 5As shown, this embodiment of the invention provides an automatic dehumidification device for the transition chamber of a vacuum glove box, specifically including a transition chamber body 1, with a sealing door 2 on the side of the transition chamber body 1. A straight rod 5 is fixedly connected to the bottom of the interior of the transition chamber body 1, and a placement platform 6 is fixedly connected to the top of the straight rod 5. The design of the placement platform 6 facilitates the placement of items on the platform 6 and allows the operator to easily retrieve them using gloves. Several sets of fixing balls 7 are fixedly connected to the top of the placement platform 6, and several sets of ventilation openings 8 are provided at the top of the placement platform 6. Placing items on the fixing balls 7 helps to reduce the contact area, increase the heating area, and accelerate the dehumidification time. The design of the ventilation openings 8 also allows more hot air to rise from the bottom, dehumidifying the bottom of the items. A mounting block 9 is fixedly connected to the side of the transition chamber body 1 away from the sealing door 2. Screw holes 10 are fixedly connected to the four corners of the mounting block 9. The transition chamber body 1 is connected and fixed to the glove box by the cooperation of bolts and screw holes 10.

[0029] Please see Figures 1 to 5 As shown, the interior of the transition chamber body 1 is equipped with a dewatering mechanism 3. The dewatering mechanism 3 includes an air inlet pipe 30 fixedly connected to the top of the transition chamber body 1. A cylinder 31 is fixedly connected to the bottom end of the air inlet pipe 30. A heating mesh 32 is fixedly connected inside the cylinder 31. A rotating shaft 33 is rotatably connected to the bottom end of the cylinder 31. A set of fan blades 34 is fixedly connected to the top end of the rotating shaft 33. An air storage plate 35 is fixedly connected to the bottom end of the rotating shaft 33. A T-shaped hole 36 is opened inside the rotating shaft 33. An L-shaped hole 37 is opened inside the air storage plate 35. The T-shaped hole 36 and the L-shaped hole 37 are connected. A set of air outlet holes 38 is opened at the bottom end of the L-shaped hole 37. A rear plate 390 is fixedly connected to the rear side inside the transition chamber 1. A sound wave sensor 39 is fixedly connected to the front side of the bottom end of the rear plate 390. An activated carbon mesh 11 is fixedly connected inside the cylinder 31, and the activated carbon mesh 11 is located on top of the heating mesh 32. The activated carbon mesh 11 can adsorb pungent odors in the gas. A filter 12 is fixedly connected inside the air inlet pipe 30, and the filter 12 is located on top of the activated carbon mesh 11. The filter 12 can filter and block impurities and dust in the gas, achieving a purification effect.

[0030] During operation, the power supply to the acoustic sensor 39 is turned on, and the air inlet pipe 30 is connected to an external air source. When an item is placed inside the transition chamber 1, the acoustic sensor 39 emits sound waves. The sound waves are weakened when passing through water. When the surface of the item contains moisture, the acoustic sensor 39 senses this and controls the heating grid 32 to turn on, and the external air source to input gas into the air inlet pipe 30. After passing through the heating grid 32, the gas becomes hot gas, which then drives the fan blades 34 to rotate. The fan blades 34 drive the rotating shaft 33 to rotate, and the rotating shaft 33 drives the air storage plate 35 to rotate. The hot gas enters the T-shaped hole 36 and then flows downward through the air outlet 38. When hot air is sprayed out, it will be sprayed onto the surface of the item. As the air storage plate 35 rotates, it will increase the contact area between the hot air and the item. Then, the sound wave sensor 39 of the device will emit sound waves to sense whether there is moisture on the surface of the item. If there is moisture, it will control the heating grid 32 to heat up. An external air source will start to input gas into the air inlet pipe 30. The heating grid 32 will heat the gas, and the hot air will be sprayed out through the air outlet 38. The gas will drive the rotating shaft 33 to rotate, and the rotating shaft 33 will drive the air storage plate 35 to rotate. This will help the hot air to be sprayed onto the surface of the item quickly, improve the speed and efficiency of dehydration, and realize the automatic dehydration function to prevent moisture from affecting the environment inside the vacuum glove box.

[0031] Please see Figure 4 As shown, the transition chamber body 1 is equipped with a sealing mechanism 4. The sealing mechanism 4 includes a connecting pipe 41 fixedly connected to the bottom end of the air outlet 38. A sealing plate 42 is rotatably connected inside the connecting pipe 41. A limiting block 43 is provided on the top of the sealing plate 42 near the air inlet pipe 30, and the limiting block 43 is fixedly connected to the inner wall of the connecting pipe 41. A stop block 44 is provided on the bottom of the sealing plate 42 away from the air inlet pipe 30, and the stop block 44 is fixedly connected to the inner wall of the connecting pipe 41. A gravity block 45 is fixedly connected inside the sealing plate 42 near the stop block 44. A guide plate 46 is fixedly connected inside the connecting pipe 41 away from the limiting block 43. The bottom end of the guide plate 46 is inclined towards the limiting block 43. In order to guide the hot air to the side of the sealing plate 42 near the limiting block 43, it can rotate counterclockwise.

[0032] During operation, gas enters the connecting pipe 41. Under the action of the air guide plate 46, the air guide plate 46 guides the hot gas to the side of the sealing plate 42 near the limiting block 43. At this time, the sealing plate 42 rotates counterclockwise, and under the resistance of the air guide plate 46, the side of the sealing plate 42 near the abutment block 44 contacts the bottom end of the air guide plate 46, so that the sealing plate 42 is not in a vertical state. At this time, the hot gas is sprayed downward from the side of the sealing plate 42 near the limiting block 43. After the dewatering is completed, under the action of the gravity block 45, the sealing plate 42 rotates clockwise, and the side of the sealing plate 42 near the limiting block 43 contacts the bottom end of the air guide plate 46. Under the action of block 44, the sealing plate 42 is in a horizontal state, which seals the connecting pipe 41 and prevents the inert gas to be filled in later from entering the connecting pipe 41. Then, under the action of the air guide plate 46, the hot air blows the sealing plate 42 to rotate counterclockwise, and the sealing plate 42 is not in a vertical state. After the water removal is completed, under the action of gravity block 45, the sealing plate 42 rotates clockwise, and under the action of limit block 43 and stop block 44, the sealing plate 42 is in a horizontal state, which seals the connecting pipe 41 and prevents the inert gas to be filled in later from entering the connecting pipe 41.
