[0025] To explain the technical content and structural features of this utility model in detail, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0026] Please see Figure 1 , Figure 2 and Figure 4 This utility model's chemical synthesis glove box 100 is applied in the new energy industry and can meet the needs of conducting chemical experiments under anhydrous and oxygen-free conditions. The chemical synthesis glove box 100 includes a frame 10, a box body 20, a transition chamber 30, a chemical synthesis device 40, a filter 50, and a water and oxygen analyzer 60, a gas purification system 70, and a vacuum system 80 located outside the box body 20; optionally, it can be combined with... Figure 1 and Figure 2 As an example, the rack 10 is a square frame. Obviously, depending on the actual needs, the rack 10 can also be other shapes well known in the art, so it is not specified. Figure 1 and Figure 2 The above is the limit.

[0027] The housing 20 is mounted on the frame 10, and the frame 10 provides support for the housing 20; alternatively, it can be combined with... Figure 1 and Figure 2 As an example, the housing 20 is located directly above the frame 10. In addition, the housing 20 is square. Obviously, depending on the actual needs, the housing 20 can also be other shapes known in the art.

[0028] The transition chamber 30 is connected to the housing 20 to facilitate the loading and unloading of items, as well as the purging operation of inert gases (such as, but not limited to, high-purity nitrogen); alternatively, in Figure 1 In this example, one end of the transition compartment 30 is fixedly connected to the side wall 21 of the housing 20 via a flange 90 to facilitate the assembly of the transition compartment 30 with the side wall 20 of the housing 20. Obviously, depending on actual needs, the assembly method of the transition compartment 30 with the side wall 20 of the housing 20 can also be other methods well known in the art, therefore, it is not considered... Figure 1 The above is for reference only. Additionally, a viewing panel 22 and operating gloves 23 are provided on the side wall 21 of the enclosure 20 to facilitate quick operation and observation by the operator; optionally, [the following is also provided]. Figure 1 As an example, the viewing panel 22 is a glass panel, preferably a tempered glass panel, to avoid injury to the operator if the viewing panel 22 breaks; in addition, the operating glove 23 is an elastic glove so that the operator can perform chemical experiments on the chemical synthesis equipment 40 inside the housing 20 through the operating glove 23; obviously, depending on actual needs, the viewing panel 22 and the operating glove 23 can also be other structures known in the art.

[0029] The chemical synthesis equipment 40 and the filter 50 are located inside the housing 20 to meet the need for the chemical synthesis equipment 40 to perform chemical experiments under anhydrous and oxygen-free conditions; alternatively, as an example, the filter 50 is a glass frit filter to more effectively filter out particles, etc.

[0030] The inlet 71 of the gas purification system 70 is connected to the filter 50, and the outlet 72 of the gas purification system 70 is connected to the housing 20; optionally, at... Figure 2 In this example, the gas purification system 70 is located below the housing 20 and mounted on the frame 10. The frame 10 provides support for the gas purification system 70 and also makes the arrangement of the gas purification system 70 on the frame 10 more reasonable and compact. Obviously, the installation position of the gas purification system 70 can be other than that required, so it is not specified here. Figure 2 The above is the limit. Also, at... Figure 4As an example, the gas purification system 70 includes a deoxygenation unit 70a, a water removal unit 70b, an impurity removal unit 70c, and a circulating fan 70d that sequentially sends the gas filtered by the filter 50 into the deoxygenation unit 70a, the water removal unit 70b, and the impurity removal unit 70c to meet the needs of the gas purification system 70 to circulate and purify the gas in the housing 20.

[0031] Vacuum system 80 and water-oxygen analyzer 60 are respectively connected to chamber 20. Vacuum system 80 is configured to evacuate chamber 20, and water-oxygen analyzer 60 is configured to analyze the water-oxygen content inside chamber 20; optionally, combined with Figure 1 and Figure 2 As an example, the vacuum system 80 is located below the housing 20 and mounted on the frame 10. The water and oxygen analyzer 60 is mounted and connected to the side wall 21 of the housing 20, and the side wall 21 of the housing 20 where the water and oxygen analyzer 60 is located is adjacent to the side wall 21 of the housing 20 where the viewing panel 22 is located. For example, in Figure 1 In this configuration, the side wall 21 of the enclosure 20 containing the visual panel 22 is the front side wall, and the side wall 21 of the enclosure 20 containing the water and oxygen analyzer 60 is the right side wall, to facilitate operation. Obviously, depending on actual needs, the side walls 21 of the enclosure 20 containing the visual panel 22 and the water and oxygen analyzer 60 can also be side walls in other directions of the enclosure 20; therefore, they are not considered as such. Figure 1 The above is a limited description. More specifically, as follows:

[0032] like Figure 1 and Figure 2 As shown, as an example, the transition chamber 30 is equipped with a pressure gauge 31, a movable shelf 32, and an operating handwheel 33. The operating handwheel 33 is configured to open and close the door 34 of the transition chamber 30 to facilitate the entry and exit of goods and the replacement of inert gas. Specifically, in Figure 1 As an example, the transition compartment 30 is also equipped with a hydraulic cylinder 35 for hydraulically fastening the compartment door 34 to improve the reliability of the compartment door 34 when it is closed.

[0033] For example Figure 1 and Figure 2As shown, as an example, the housing 20 is connected to an inert gas delivery pipe 24, a pressure balancing pipe 25, a cooling water inlet pipe 26, and a cooling water outlet pipe 27. A valve body 241 is provided on the inert gas delivery pipe 24, a valve body 251 on the pressure balancing pipe 25, a valve body 261 on the cooling water inlet pipe 26, and a valve body 271 on the cooling water outlet pipe 27. Therefore, the inert gas delivery pipe 24 is used to meet the need for inputting inert gas into the housing 20; the pressure balancing pipe 25 is used to ensure pressure balance within the housing 20. Furthermore, the valve bodies 241, 251, 261, and 271 are used to correspondingly close or open the inert gas delivery pipe 24, the pressure balancing pipe 25, the cooling water inlet pipe 26, and the cooling water outlet pipe 27.

[0034] like Figure 3 As shown, as an example, the water and oxygen analyzer 60 includes a touch screen 61 and an oxygen sensor 62 and a moisture sensor 63 electrically connected to the touch screen 61. Therefore, the oxygen sensor 62 is used to detect the oxygen content inside the chamber 20 in real time; the moisture sensor 63 is used to detect the moisture content inside the chamber 20 in real time; and the touch screen 61 is used to process the detection information fed back by the oxygen sensor 62 and the moisture sensor 63, and to display the processed water and oxygen content. Since the specific structure and working principle of the water and oxygen analyzer 60 are well known in the art, they will not be described in detail here.

[0035] like Figure 1 As shown, as an example, the chemical synthesis apparatus 40 includes an electronic scale 41, a thermometer 42, an operating table 43, a stirrer 44, a condenser 45, a flask 46, and a heating pan 47 to meet the needs of operators conducting various chemical experiments. Specifically, in Figure 1 In this example, the operating table 43 is an iron stand, the stirrer 44 is an electric stirrer, the condenser 45 is a spherical glass condenser, the flask 46 is a three-necked flask, and the heating pot 47 is an electric heating electromagnetic oil bath; correspondingly, silicone oil is added to the heating pot 47; in addition, an L-shaped shelf 28 is also provided inside the cabinet 20, and the L-shaped shelf 28 is located on the side wall 21 of the cabinet 20 opposite to the visible panel 22.

[0036] like Figure 5 As shown, as an example, the deoxygenation unit 70a is a reduced iron powder packing processor to effectively improve deoxygenation capacity; alternatively, in Figure 5As an example, the reduced iron powder packing processor includes porous packing balls 70a1, a cloth bag 70a2 filled within the porous packing balls 70a1, and reduced iron powder 70a3 filled within the cloth bag 70a2. This design effectively increases the packing adsorption area and porosity of the deoxygenation unit 70a, thereby more effectively improving the deoxygenation capacity. For example, the porous packing balls 70a1 are made of plastic, and the cloth bag 70a2 is made of non-woven fabric, but this is not a limitation.

[0037] like Figure 6 As shown, as an example, the dewatering unit 70b is a flake caustic soda packing processor to effectively improve dewatering capacity; alternatively, in Figure 6 As an example, the caustic soda flake packing processor includes porous packing balls 70b1 and sodium hydroxide flakes 70b2 filled within the porous packing balls 70b1. Therefore, the porous packing balls 70b1 are used to more effectively increase the packing adsorption area and porosity of the dewatering unit 70b; and the sodium hydroxide flakes 70b2 are used to further improve the water removal capacity. For example, the porous packing balls 70b1 of the dewatering unit 70b are made of plastic, but this is not a limitation.

[0038] Combination Figure 7 and Figure 8 As an example, the impurity removal unit 70c includes activated carbon packing processor 70c1 and molecular sieve packing processor 70c2 arranged in series to more effectively improve the impurity removal capability. Specifically, in Figure 7 As an example, the activated carbon packing processor 70c1 includes porous packing balls 73, which are filled with activated carbon particles 731. The porous packing balls 73 effectively increase the adsorption area and porosity of the activated carbon packing processor 70c1; the activated carbon particles 731 further enhance the purification capacity. Additionally, in... Figure 8 As an example, the molecular sieve packing processor 70c2 includes porous packing balls 74, which are filled with molecular sieve particles 741. Therefore, the porous packing balls 74 effectively increase the adsorption area and porosity of the molecular sieve packing processor 70c2, while the molecular sieve particles 741 further enhance the purification capacity. For example, the porous packing balls 73 of the activated carbon packing processor 70c1 and the porous packing balls 74 of the molecular sieve packing processor 70c2 are both made of plastic, but this is not a limitation.

[0039] Compared with existing technologies, the vacuum system 80 ensures that the chamber 20 is in a vacuum state before an inert gas (such as, but not limited to, high-purity nitrogen) is introduced into it. The design of the gas purification system 70, which includes a deoxygenation unit 70a, a water removal unit 70b, an impurity removal unit 70c, and a circulating fan 70d that sequentially sends the gas filtered by the filter 50 into the deoxygenation unit 70a, the water removal unit 70b, and the impurity removal unit 70c, allows for rapid and convenient treatment of moisture, oxygen, and impurities introduced into the chamber 20. The water and oxygen content in the chamber 20 is monitored in real time by the water and oxygen analyzer 60, ensuring that the chemical synthesis equipment 40 within the chamber 20 can conduct experiments when the water and oxygen content meets controllable parameters. Therefore, the glove box 100 for chemical synthesis of this invention has the advantages of rapid and convenient water and oxygen analysis and control. Furthermore, the chemical synthesis equipment 40 located within the chamber 20 allows for various anhydrous and oxygen-free chemical synthesis experiments, meeting the high-quality requirements of new energy materials.

[0040] It should be noted that the aforementioned vacuum system 80 can be a vacuum pump; furthermore, in conjunction with... Figure 1 and Figure 2 As an example, the vacuum pump is connected to the housing 20 via the vacuum tube 81. In addition, to facilitate the wiring and operation of the glove box 100 for chemical synthesis of this invention, an electrical control box 11 is mounted on the frame 10.

[0041] The above-disclosed examples are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall fall within the scope of the present utility model.
