Description

Technical Field

[0001] The utility model relates to the field of vacuum glove box structure design, in particular to a split type vacuum purification glove box. Background Art

[0002] According to a split-type vacuum glove box structure disclosed on the patent website (authorization publication number: CN221021079U), "a transition chamber is fixedly connected to one side of the glove box body, and a purge box is fixedly connected to the other side of the glove box body. The purge box is connected to the separation box via a first pipe. Three storage mechanisms are arranged in sequence from top to bottom within the separation box. The three storage mechanisms store molecular sieves, copper catalysts, and activated carbon in sequence from top to bottom. An exhaust mechanism is arranged between the separation box and the purge box, and the exhaust mechanism is connected to the purge box and the glove box body."

[0003] In view of the above description, the applicant believes that the following problems exist:

[0004] During use of the utility model, since three storage mechanisms are arranged in sequence from top to bottom in the separation box; the three storage mechanisms store molecular sieves, copper catalysts and activated carbon in sequence from top to bottom, the applicant can infer from this paragraph and the drawings in the specification that the storage mechanisms are arranged vertically in the separation box. This arrangement requires manual movement of the storage mechanisms to an appropriate height of the separation box when the storage mechanisms need to be replaced. When the storage mechanisms are moved to the highest position of the separation box, the human body will have a higher center of gravity and be prone to the risk of falling. At the same time, the structure disclosed in the utility model lacks the ability to absorb vacuum. Therefore, it is necessary to improve a split vacuum purification glove box to solve the above problems. Utility Model Content

[0005] In order to overcome the problem that when the storage mechanism needs to be replaced, the storage mechanism needs to be manually moved to an appropriate height of the separation box. When the storage mechanism is moved to the highest position of the separation box, the human body will have a high center of gravity and is prone to falling.

[0006] The technical solution of the present utility model is: a split vacuum purification glove box, comprising a base, a glove box arranged above the base and an exhaust mechanism arranged on the side of the base, a purification component is provided inside the base, the purification component comprises a fixed plate, movable plates distributed on both sides of the fixed plate, a screw vertically inserted into the movable plate, one end of the screw is provided with a forward-rotating screw thread, and the other end is provided with a reverse-rotating screw thread, and a purification box can be placed between the fixed plate and the movable plate.

[0007] Preferably, the air in the glove box is purified by a purification component arranged in the base, and the purification box is clamped between the fixed plate and the movable plate by a movable movable plate. The reason why the movable plate can move is that a screw can be inserted into the movable plate, and a screw is inserted into the forward and reverse screw threads of the screw. When the screw is turned, the movable plates at both ends can approach or move away from each other. When the two movable plates approach each other, they can clamp the purification box. When the two movable plates move away from each other, the purification box is released, which makes it convenient to replace the purification box.

[0008] Preferably, there is a nut fixing seat at the bottom of the movable plate, moving blocks are provided on both sides of the nut fixing seat, and rollers are provided at the bottom of the moving block. Specifically, the nut fixing seat under the movable plate cooperates with the screw. In order to ensure that the movable plate can run smoothly, there are moving blocks on both sides of the nut fixing seat, and the rollers at the bottom of the moving block can allow the movable plate to move smoothly.

[0009] Preferably, the length direction of the movable plate is perpendicular to the width direction of the movable block, and the width of the movable plate is smaller than the length of the movable block. An "L"-shaped bracket 1 can be formed between the movable plate and the movable block, and the fixed plate is provided with brackets 2 on both sides that are mirror images of the "L"-shaped bracket 1. The purification box is placed between the brackets 1 and 2, and the brackets 1 and 2 can support the purification box to prevent it from falling onto the base. At the same time, when taking or placing the purification box, the purification box slides on the brackets 1 and 2, eliminating the trouble of carrying the purification box.

[0010] Preferably, the movable plate is provided with a through hole, through which the purification component can be connected to achieve circulation between the purification component and the glove box.

[0011] Preferably, the movable plate on the right side of the fixed plate is connected to a hose 1, and the hose 1 can also be connected to the right side of the glove box. A one-way valve is provided in the hose 1, and the airflow in the glove box can only enter the purification component from the glove box through the hose 1. The purification component is connected to the glove box through the hose 1. A one-way valve is provided in the hose 1. When the airflow in the glove box can only enter the purification component through the hose 1, the backflow of the airflow in the glove box can be effectively prevented.

[0012] Preferably, the movable plate on the left side of the fixed plate is connected to hose 2, and the hose 2 can also be connected to the exhaust mechanism, and the exhaust mechanism is also connected to hose 3, and the hose 3 is connected to the left side of the glove box. A one-way valve is provided in the hose 2, and the airflow in the purification box can only enter the exhaust mechanism through hose 2. A one-way valve is provided in the hose 3, and the airflow extracted by the exhaust mechanism can only enter the glove box through hose 3. The exhaust mechanism can provide power for the circulation between the glove box and the purification component. At the same time, hose 2 and hose 3 are both provided with one-way valves, which can effectively prevent the airflow from flowing back. At the same time, the one-way valve at hose 3 can also prevent the airflow from entering the glove box.

[0013] Preferably, the exhaust mechanism is also connected to a hose four, through which the exhaust mechanism can directly discharge the gas purified by the purification component to form a vacuum environment in the glove box. After the vacuum environment in the glove box is formed, a nitrogen gas pipe is installed at the port of the hose four away from the exhaust mechanism to fill the glove box with nitrogen.

[0014] Beneficial effects of the utility model:

[0015] 1. The air in the glove box is purified by a purification component arranged in the base. The purification box is clamped between the fixed plate and the movable plate through a movable movable plate. When the two movable plates are close to each other, the purification box can be clamped. When the two movable plates are away from each other, the purification box is released, which makes it easy to replace the purification box.

[0016] 2. When the glove box needs to be filled with high-concentration inert gas, a vacuum mechanism is used to evacuate the glove box. After the vacuum is evacuated, the glove box can be filled with inert gas through the vacuum mechanism. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] See also Figures 1-6 The utility model provides an embodiment: a split vacuum purification glove box, comprising a base 1, a glove box 2 arranged above the base 1 and an exhaust mechanism 3 arranged on the side of the base 1, a purification component 4 is provided inside the base 1, and the purification component 4 includes a fixed plate 41, movable plates 42 distributed on both sides of the fixed plate 41, and a screw 43 vertically inserted into the movable plate 42, one end of the screw 43 is provided with a forward-rotating screw thread 431, and the other end is provided with a reverse-rotating screw thread 432, and a purification box 44 can be placed between the fixed plate 41 and the movable plate 42. The air in the glove box 2 is purified by the purification component 4 arranged in the base 1, and the purification box 44 is clamped between the fixed plate 41 and the movable plate 42 through the movable movable plate 42. The reason why the movable plate 42 can move is that the movable plate 42 can be inserted with a screw 43, and the screw 43 is inserted at the forward thread 431 and the reverse thread 432 of the screw 43. When the screw 43 is turned, the movable plates 42 at both ends can approach or move away from each other. When the two movable plates 42 approach each other, they can clamp the purification box 44. When the two movable plates 42 move away from each other, the purification box 44 is released, which makes it convenient to replace the purification box 44.

[0026] See also Figure 2-Figure 3In this embodiment, the bottom of the movable plate 42 has a nut fixing seat 421, and movable blocks 422 are provided on both sides of the nut fixing seat 421. The bottom of the movable block 422 has a roller 4221. Specifically, the nut fixing seat 421 below the movable plate 42 cooperates with the screw 43. To ensure the smooth operation of the movable plate 42, movable blocks 422 are provided on both sides of the nut fixing seat 421. The rollers 4221 at the bottom of the movable block 422 allow the movable plate 42 to move smoothly. The length of the movable plate 42 is perpendicular to the width of the movable block 422. The width of the movable plate 42 is less than the length of the movable block 422. An "L"-shaped bracket 1 4222 is formed between the movable plate 42 and the movable block 422. The fixed plate 41 is provided with a second bracket 4223 on both sides, which is a mirror image of the "L"-shaped bracket 1 4222. The purification box 44 is placed between the first bracket 4222 and the second bracket 4223. The purification box 44 can be supported by the bracket 1 4222 and the bracket 2 4223 to prevent the purification box 44 from falling on the base 1. At the same time, when taking or placing the purification box 44, the purification box 44 slides on the bracket 1 4222 and the bracket 2 4223, eliminating the trouble of carrying the purification box 44.

[0027] See also Figure 3-Figure 4In this embodiment, the movable plate 42 is provided with a through-hole 423. Through the through-hole 423, the purification assembly 4 is connected, enabling circulation between the purification assembly 4 and the glove box 2. A hose 51 is connected to the movable plate 42 on the right side of the fixed plate 41. The hose 51 can also be connected to the right side of the glove box 2. A one-way valve 6 is installed in the hose 51. Airflow from the glove box 2 can only enter the purification assembly 4 from the glove box 2 through the hose 51. The hose 51 connects the purification assembly 4 to the glove box 2. The one-way valve 6 is installed in the hose 51. When the airflow from the glove box 2 can only enter the purification assembly 4 through the hose 51, the backflow of air from the glove box 2 is effectively prevented. The movable plate 42 on the left side of the fixed plate 41 is connected to a second hose 52. This hose 52 can also be connected to the exhaust mechanism 3. This exhaust mechanism 3 is also connected to a third hose 53, which is connected to the left side of the glove box 2. A one-way valve 6 is installed within this hose 52, allowing air from the purge box 44 to enter the exhaust mechanism 3 only through this hose 52. A one-way valve 6 is installed within this hose 53, allowing air extracted by the exhaust mechanism 3 to enter the glove box 2 only through this hose 53. The exhaust mechanism 3 provides power for circulation between the glove box 2 and the purification assembly 4. Both the second and third hoses 52, 53 are equipped with one-way valves 6, effectively preventing backflow. The one-way valve 6 on hose 3, 53, also prevents air from entering the glove box 2. The exhaust mechanism 3 is also connected to a fourth hose 54. Through hose four 54, the exhaust mechanism 3 can directly discharge the gas purified by the purification component 4 to form a vacuum environment in the glove box 2. After the vacuum environment in the glove box 2 is formed, a nitrogen gas pipe is installed at the port of hose four 54 away from the exhaust mechanism 3 to fill nitrogen into the glove box 2.

[0028] During work, after the operator places the required products in the glove box 2, the switch of the exhaust mechanism 3 can be turned on to allow the air flow to flow from the glove box 2 through the hose 1 51 into the purification component 4, and then enter the hose 2 52 after purification and filtration by the purification component 4, and then enter the exhaust mechanism 3 from the hose 2 52. Then the exhaust mechanism 3 sprays the air flow toward the hose 3 53, and finally the air flow through the hose 3 53 returns to the glove box 2. When the glove box 2 needs to be vacuumed, the interface end of hose three 53 is blocked and the air in the glove box 2 is extracted at hose two 52. The air will be extracted from the glove box 2 through hose one 51, purification component 4, hose two 52, and then discharged from hose four 54. The air here has been purified by the purification component 4 and can be discharged directly from hose four 54 without the need for further collection, filtration, and non-toxic and harmless treatment. Usually, after the glove box 2 is vacuumed, it is also necessary to fill the glove box 2 with inert gas in order to maintain the air pressure difference in the glove box 2. The operator can connect a nitrogen gas pipe at hose four 54 to transmit the nitrogen from hose four 54 to the exhaust mechanism 3, and then discharge it from the exhaust mechanism 3 through hose three 53 into the glove box 2. When the purification box 44 in the purification component 4 is dirty, the operator needs to turn the screw 43 to move the movable plates 42 on the left and right sides of the fixed plate 41 away from the fixed plate 41. The final movement effect can be referred to Figure 5 In the middle I state, the operator then moves the small flatbed cart to the device and drags out the dirty purification box 44 until the dirty purification box 44 is dragged onto the small flatbed cart. The new purification box 44 is then transported to the side of the equipment by the small flatbed cart and the new purification box 44 is pushed from the small flatbed cart to the bracket 1 4222 and the bracket 2 4223. The operator then turns the screw 43 in the opposite direction to move the movable plates 42 on the left and right sides of the fixed plate 41 toward the fixed plate 41. The fixed plate 41 and the movable plate 42 can then clamp the purification box 44. At the same time, there is a rubber ring at the inlet end face and the outlet end face of the purification box 44 to provide a seal for the purification component 4 to prevent the gas in the glove box 2 from leaking out. The reason why the two moving plates 42 can move toward and away from each other is that one end of the screw 43 has a forward-spinning screw thread 431 and the other end has a reverse-spinning screw thread 432. When the screw 43 is turned, the moving plate 42 on the forward-spinning screw thread 431 and the moving plate 42 on the reverse-spinning screw thread 432 can move away from or toward each other. For a specific diagram, please refer to Figure 6 .

[0029] After the completion, the operator turns the screw 43 in the opposite direction to move the movable plates 42 on the left and right sides of the fixed plate 41 toward the fixed plate 41, so that the fixed plate 41 and the movable plates 42 can clamp the purification box 44 to solve the problem of manually moving the storage mechanism to the appropriate height of the separation box. When the storage mechanism is moved to the highest position of the separation box, the human body will have a higher center of gravity and is prone to falling.
