Technical Field
[0001] This utility model relates to the field of laboratory equipment technology, and in particular to a glove box with a purification system. Background Technology
[0002] A glove box is a laboratory device that fills the chamber with high-purity inert gas and circulates and filters out active substances. It is also called an inert gas protection box or dry box. It is widely used in ultrapure environments that are free of water, oxygen, and dust, such as lithium-ion batteries and materials, semiconductors, supercapacitors, special lamps, laser welding, and brazing. This product is an ideal device for scientific experiments in universities, research institutions, and enterprise laboratories, and is widely used in biochemistry, metallurgy, electronics, chemical industry, geology, mining, and medicine.
[0003] Traditional purification systems' glove boxes require a relatively long time to transfer items in the transition chamber. Each entry and exit requires vacuuming, gas introduction, and pressure rebalancing, making the process complex and affecting the work efficiency of staff. Furthermore, traditional purification systems' glove boxes require an ultra-low water and oxygen environment during use, which is also relatively cumbersome and can easily affect the equipment's working efficiency.
[0004] Therefore, those skilled in the art have provided a glove box with a purification system to solve the problems mentioned in the background art. Summary of the Invention
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a glove box with a purification system. A fixed column moves the cover plate, and rotating a knob moves the cover plate to completely seal the transition box. A second air pump is activated to expel air from the transition box, and then a first air pump is activated to release inert gas from an inert gas tank into the transition box. A sliding chute then moves, activating a first motor that drives a first threaded rod to rotate, moving the clamped item into the operating box. This mechanism ensures that no impurities or unknown gases enter the operating box when items are placed inside, effectively creating and controlling an isolated operating environment.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] A glove box with a purification system includes an operating box, a transition box on one side of the operating box, and a box body fixedly connected to one side of the operating box. A first partition is slidably connected inside the box body. A first connector is fixedly connected to the center of the lower surface of the first partition. A first threaded rod is rotatably connected inside the first connector. A first motor is fixedly connected to the end of the first threaded rod away from the operating box. A first air pump is fixedly connected to the front end of the outer wall of one side of the operating box. A second air supply pipe is fixedly connected to the input end of the first air pump. An inert gas cylinder is fixedly connected to the lower surface of the second air supply pipe. A first air supply pipe is fixedly connected to the rear end of the outer wall of the first air pump. A second air pump is fixedly connected to the rear end of the outer wall of one side of the operating box. An exhaust pipe is fixedly connected to the outer wall of one side of the second air pump. A third air supply pipe is fixedly connected to the front end of the outer wall of the second air pump.
[0008] A second motor is fixedly connected to one side of the upper surface of the first partition plate. A bidirectional lead screw is fixedly connected to the output end of the second motor. A retainer is threaded to both the front end and the rear end of the bidirectional lead screw. A connecting rod is fixedly connected to the outer wall of the retainer. A fixing clamp is fixedly connected to the side of the connecting rod away from the retainer.
[0009] The above technical solution uses a second motor to drive a clamping clamp to hold the item to be placed. After clamping, a first motor drives a first threaded rod to rotate, moving the clamped item into the operating box. Then, a second air pump discharges the air from the transition box, and a first air pump discharges the inert gas from the inert gas tank into the transition box. This mechanism can effectively place items into the operating box while ensuring an ultra-low water and oxygen environment.
[0010] Furthermore, a purification mechanism is provided on the lower outer wall of the operation box. The purification mechanism includes a first outer shell fixedly connected to the lower surface of the operation box, a fan fixedly connected to the inner wall of the first outer shell, a first air inlet pipe fixedly connected to the input end of the fan, and a second air inlet pipe fixedly connected to the output end of the fan.
[0011] The above technical solution allows the gas to be extracted from the control box and introduced into the purification unit.
[0012] Furthermore, the end of the second air inlet pipe away from the fan is sequentially and fixedly connected to a first air baffle valve, a purification column, a second air baffle valve, a third air inlet pipe, a third air baffle valve, a solvent column, a fourth air baffle valve, and a fourth air inlet pipe. The end of the fourth air inlet pipe away from the solvent column is fixedly connected to an operation box.
[0013] Through the above technical solution, the gas in the operating chamber can be discharged into the purification column and solvent column for gas purification, effectively ensuring the circulation of low water and oxygen environment gas in the operating chamber.
[0014] Furthermore, table legs are fixedly connected to the four corners of the lower surface of the control box, and plastic gloves are fixedly connected to the middle of the front outer wall of the control box. A second outer shell is fitted around the bidirectional lead screw, and the second outer shell is fixedly connected to the upper surface of the first partition.
[0015] The above technical solution provides support for the control box through the table legs and protection for the bidirectional lead screw through the second outer shell.
[0016] Furthermore, a control box is fixedly connected to one side of the lower end of the outer wall of the front end of the operation box, the lower surface of the first motor is fixedly connected to the box body, and fixed columns are fixedly connected to the front and rear ends of the outer wall of the box body away from the operation box. A positioning plate is rotatably connected to the outer wall of the fixed column, and a second threaded rod is rotatably connected to the middle of one side of the outer wall of the positioning plate. A knob is fixedly connected to one side of the outer wall of the second threaded rod, and a cover plate is fixedly connected to the end of the second threaded rod away from the knob.
[0017] Through the above technical solution, the control box can control the complete operation of the equipment, the cover plate can provide a sealed environment for the transition box, the positioning plate can restrict the movement of the cover plate, and the mechanism can effectively discharge and draw in gas.
[0018] Furthermore, the outer wall of the bidirectional lead screw is rotatably connected to two second connectors. The lower surface of one second connector is fixedly connected to the rear end of the upper surface of the first partition plate, and the lower surface of the other second connector is fixedly connected to the middle part of one side of the upper surface of the first partition plate.
[0019] The above technical solution allows for the restriction of the movement of the bidirectional lead screw through this mechanism.
[0020] Furthermore, a sliding groove is fixedly connected to the inner wall of the operating box near the transition box, and a second partition is slidably connected to the upper surface of the sliding groove. A limiting plate is fixedly connected to one outer wall of the cover plate, and the limiting plate is rotatably connected to the second threaded rod.
[0021] The above technical solution restricts the movement of the second threaded rod by means of a limiting plate, and the mechanism provides a sealing function when the gas in the transition box is discharged.
[0022] Furthermore, a sealing gasket is fixedly connected to the outer wall of the cover plate on the side away from the knob;
[0023] The above technical solution and the mechanism can improve the sealing performance of the transition box.
[0024] This utility model has the following beneficial effects:
[0025] 1. This utility model proposes a glove box with a purification system. A fixed column drives the cover plate to move, and then rotating the knob moves the cover plate to completely seal the transition box. The second air pump is started to exhaust the air in the transition box, and then the first air pump is started to discharge the inert gas in the inert gas tank into the transition box. Then the slide is moved and the first motor is started. The first motor drives the first threaded rod to rotate and move the clamped item into the operating box. This mechanism can ensure that no impurities or unknown gases enter the operating box when items are put into it, and can effectively create and control an isolated operating environment.
[0026] 2. The glove box with a purification system proposed in this utility model uses a second motor to drive a bidirectional lead screw to rotate. The bidirectional lead screw drives the fixing device to move towards the center, and at the same time drives the fixing clamp to move towards the center to clamp the items. This mechanism can effectively prevent the items from shifting during the movement when they are put into the operating box. Attached Figure Description
