[0026] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.
[0027] like Figures 1 to 4 As shown, the copper oxide reduction auxiliary device in one embodiment of the utility model comprises a bottle body 1 and a bottle cap 2, and the bottle cap 2 covers the upper end of the bottle body 1. The upper end of the bottle body 1 is fixedly connected with a bottle mouth 13, and the bottle cap 2 is fixedly connected with a cap brim 22 matching the bottle mouth 13, and the inner wall of the bottle mouth 13 and the outer wall of the cap brim 22 are tightly fitted. The bottle mouth 13 and the cap brim 22 are both made of frosted material, which can greatly improve the sealing of the reduction auxiliary device and prevent the gas in the bottle body 1 from leaking from the connection between the bottle body 1 and the bottle cap 2 as much as possible.
[0028] like Figures 1 to 4 As shown, the bottle body 1 is provided with an exhaust port 11 and a liquid discharge port 12, the exhaust port 11 is used to discharge the gas generated by reducing copper oxide, and the liquid discharge port 12 is used to discharge the liquid generated by reducing copper oxide. The exhaust port 11 is located at the upper end of the liquid discharge port 12, and a valve 4 is fixedly connected to the liquid discharge port 12. When liquid discharge is required, the valve 4 can be opened to discharge liquid. When liquid discharge is not required, the liquid is temporarily stored in the bottle body 1 and is not discharged.
[0029] During actual use, the exhaust port 11 will be connected to a rubber tube, and an exhaust device such as an exhaust fan will be installed at the end of the rubber tube away from the exhaust port 11. The hydrogen used to reduce the copper oxide in the bottle body 1 will be discharged through the rubber tube and the exhaust fan, and the hydrogen will be led to a safe location to avoid damage to the human body caused by hydrogen leakage as much as possible.
[0030] Specifically, Figures 1 to 4As shown in the figure, a connection port 21 is fixedly connected to the upper end of the bottle cap 2, and a conduit 3 matching the connection port 21 is installed on the bottle cap 2. The connection port 21 is connected to the exhaust pipe of the reduction device. The water and hydrogen generated by the reduction device are transported to the connection port 21 through the exhaust pipe, then transported from the connection port 21 into the conduit 3, and finally transported into the bottle body 1. After cooling, the water vapor condenses into water, thereby realizing gas-liquid separation.
[0031] Preferably, in the initial state, a part of water is filled inside the bottle body 1 so that the liquid level of the water is not lower than the lower end surface of the conduit 3, that is, the output end of the conduit 3 is located in the water. When the gas, water vapor, and water in the conduit 3 are output, they directly enter the water inside the bottle body 1 and can exchange heat. Since hydrogen is insoluble in water, the hydrogen bubbles upward in the form of bubbles. That is, the hydrogen is always above the water, and the hydrogen can be discharged from the bottle body 1 through the exhaust port 11. When there is too much water in the bottle body 1, the valve 4 can be opened to discharge a part of the water. During the process of discharging water, it should be noted that the liquid level of the water is not lower than the lower end surface of the conduit 3.
[0032] The reduction auxiliary device is generally used after the sample test is completed. It is necessary to take out the copper oxide and place it in the reduction device, connect the reduction device and the reduction auxiliary device, and confirm that the valve 4 is in the closed state. Connect the exhaust port 11 to the exhaust pipe, and the end of the exhaust pipe away from the exhaust port 11 is connected to the exhaust fan. The reduction device performs the reduction step, and hydrogen, water vapor, and water are slowly transported from the reduction device to the reduction auxiliary device and flow into the bottle body 1 through the conduit 3. The gas-liquid separation of hydrogen, water vapor, and water is realized in the bottle body 1. After the problem of the copper oxide is reduced to a certain extent, the connection between the reduction device and the reduction auxiliary device is disconnected, and the copper is taken out for standby.
[0033] In this embodiment, by setting the bottle body 1 and the bottle cap 2, the sealed storage of hydrogen, water vapor, and water can be realized, so that hydrogen, water vapor, and water can be cooled inside the bottle body 1, and the separation of hydrogen and water can be realized. By setting the exhaust port 11 and the liquid discharge port 12, hydrogen and liquid can be discharged from the bottle body 1 respectively to realize gas-liquid separation, and by connecting the exhaust pipe to the bottle body 1, the hydrogen can be discharged to a safe position, and the situation that hydrogen is exposed to the air and causes harm to the human body can be avoided as much as possible. And the structure of the reduction auxiliary device is simple and the operation is convenient.
[0034] In another embodiment, when copper oxide reacts with oxygen and copper under a high-temperature environment using hydrogen to generate hydrogen, water vapor, and water, after hydrogen, water vapor, and water enter the bottle body 1, the temperature inside the bottle body 1 will be high, causing the water inside the bottle body 1 to evaporate and reducing the efficiency of gas-liquid separation. To solve the above problems, as Figures 5 to 6As shown in the figure, a base 5 is installed at the lower end of the bottle body 1, and the base 5 can improve the stability of the bottle body 1 when placed on the table. The base 5 has a cavity 53, and an air inlet 51 and an air outlet 52 are also installed on the base 5. The air inlet 51 is arranged at one end of the base 5 away from the air outlet 52. A connecting pipe 6 is installed between the exhaust port 11 and the air inlet 51, and an exhaust pipe and an exhaust fan are arranged on the air outlet 52.
[0035] Specifically, hydrogen is discharged through the exhaust port 11, the connecting pipe 6, the base 5 and the exhaust pipe. During the discharge of hydrogen, heat exchange occurs between the bottle body 1 and the base 5. When hydrogen passes through the cavity 53, a part of the heat will be carried away, thereby reducing the temperature of the liquid in the bottle body 1 and improving the efficiency of gas-liquid separation.
[0036] As Figure 6 shown in the figure, a storage groove 54 for storing the connecting pipe 6 is also provided on the base 5. When the connecting pipe 6 is not needed, the connecting pipe 6 can be placed in the storage groove 54 to realize the storage of the connecting pipe 6.
[0037] When the bottle body 1 urgently needs to be cooled down, a cooling pad 7 can be placed between the bottom wall of the bottle body 1 and the base 5. The cooling pad 7 can improve the cooling efficiency of the gas-liquid in the bottle body 1, thereby improving the efficiency of gas-liquid separation.
[0038] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model.
