DETAILED DESCRIPTION

[0027] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0028] like Figure 1 As shown, the utility model provides a copper oxide preparation device, including a reaction tank body 1, a feeding mechanism 2, and a circulating gas delivery mechanism 6. The feeding mechanism 2 is connected to the reaction tank body 1. The reaction tank body 1 is a place where copper oxide is generated by reaction. The feeding mechanism 2 is a supplementary mechanism for metal copper powder, which is used to add metal copper powder to the reaction tank body 1. The circulating gas delivery mechanism 6 is used to input oxygen into the reaction tank body 1, so that the oxygen reacts with the copper powder to generate copper oxide.

[0029] like Figure 2 , Figure 3As shown, in this embodiment, the feeding mechanism 2 includes a copper powder feeding bin 21, and the copper powder feeding bin 21 is connected to the reaction tank body 1 through a feeding pipe 22, and a discharge port is provided at the bottom of the reaction tank body 1, and the discharge port is connected to the copper dissolving tank 3, that is, the copper powder feeding bin 21 can be connected to the top opening of the tank body through the feeding pipe 22, and the discharge port at the bottom of the tank body can be directly connected to the copper dissolving tank 3, so that the copper oxide produced by the reaction is transported to the copper dissolving tank 3. In addition, a stirring blade (not shown in the figure) is provided at the connection between the feeding pipe 22 and the top of the reaction tank body 1, and the stirring blade can evenly disperse the metal copper powder or copper oxide powder transported to the tank body.

[0030] like Figure 2 , Figure 3 As shown, in this embodiment, a valve core 4 is provided at the discharge port of the reaction tank body 1, and a valve stem 5 is provided at the bottom of the valve core 4. The valve core 4 is connected to a driving assembly (not shown in the figure) through the valve stem 5. The driving assembly drives the valve core 4 to move up and down along the axial direction of the discharge port, thereby closing or opening the discharge port, that is, the valve core 4, the valve stem 5 and the driving assembly constitute a discharge valve to control the amount of copper oxide powder entering the copper dissolving tank 3, thereby controlling the reaction rate. In addition, the driving assembly can be designed as an external (external) hydraulic cylinder or cylinder. Of course, in actual design, the structure of the driving assembly can be designed according to actual needs.

[0031] like Figure 2 , Figure 3 As shown, in this embodiment, the circulating gas delivery mechanism 6 includes a circulating pump 61, an injection pipe 62 and a return pipe 63. The circulating pump 61 is arranged at the top of the reaction tank body 1, one end of the injection pipe 62 is connected to the circulating pump 61, and the other end of the injection pipe 62 extends into the bottom of the reaction tank body 1, one end of the return pipe 63 is connected to the circulating pump 61, and the other end of the return pipe 63 extends into the reaction tank body 1. The circulating gas delivery mechanism 6 can blow away the copper powder, increase the contact area between oxygen and copper powder, and is conducive to the reaction generation of copper oxide. The circulating gas delivery mechanism 6 can delay the descending speed of the copper powder, increase the reaction time of oxygen and copper powder, and improve the reaction probability of the copper powder in a single falling process. At the same time, the circulating gas delivery mechanism 6 can also play a role in drying the copper powder or oxidizing the copper powder.

[0032] Specifically, the circulation pump 61 is arranged at the top of the reaction tank body 1, and its main function is to provide power, drive the gas to circulate between the injection pipe 62 and the return pipe 63, which not only helps the uniformity of the gas distribution in the reaction tank body 1, but also enhances the contact area between the gas and the copper powder, thereby promoting the occurrence of the oxidation reaction. Secondly, the circulation pump 61 can pump the gas from the top to the bottom of the reaction tank body 1, and spray it out at a certain speed and pressure through the injection pipe 62, which can fully stir and suspend the copper powder at the bottom, so that the copper powder and the gas are more fully mixed and contacted, and the reaction efficiency is further improved. In addition, the effect of the return pipe 63 is to recycle the gas at the top of the reaction tank body 1, and send it to the circulation pump 61 for circulation again, which can not only realize the recycling of gas, reduce the waste of gas, but also maintain the stability of the gas concentration in the reaction tank body 1, which is conducive to the continuous progress of the reaction. In addition, the end of the return pipe 63 extending into the reaction tank body 1 is provided with a filter block, which is only for air or oxygen to pass through, and the filter block can filter copper oxide or unreacted copper powder.

[0033] In an optional embodiment, the portion of the injection tube 62 extending into the reaction tank body 1 is evenly distributed along the circumference of the reaction tank body 1, and the gas can be injected into the reaction tank body 1 from multiple directions at the same time, avoiding the situation where the local gas concentration is too high or too low, so that the contact between the gas and the copper powder is more uniform. Secondly, the evenly distributed injection tube 62 can increase the contact area between the gas and the copper powder, and can ensure that the copper powder is fully stirred and suspended in the reaction tank body 1, thereby increasing the contact opportunity between the gas and the copper powder and improving the reaction efficiency. In addition, this design also helps to reduce the dead angles and blind spots in the reaction tank body 1. Dead angles and blind spots are areas in the reaction tank body 1 that are difficult for the gas and copper powder to reach, which can easily lead to incomplete reactions or produce uneven products, and the injection tube 62 is evenly distributed along the circumference to ensure that the gas can cover the entire reaction tank body 1, reduce the existence of dead angles and blind spots, and thus improve the uniformity and completeness of the reaction.

[0034] like Figure 2 , Figure 3 As shown, in this embodiment, a conical section 11 is provided at the bottom of the reaction tank body 1, and the diameter of the conical section 11 is gradually reduced from top to bottom, so that the copper powder or copper oxide powder can be gathered at the discharge port. In addition, an air cavity 12 is provided below the conical section 11, and a plurality of reinforcing ribs (not shown in the figure) are provided between the air cavity 12 and the conical section 11. The reinforcing ribs divide the air cavity 12 into a plurality of spaces, two of which are respectively connected to the two injection pipes 62, and the two spaces are provided with openings on one side facing the discharge port, so as to facilitate the circulation of air or oxygen, and such a setting can enhance the impact force of the gas injected into the tank body by the injection pipe 62, and can further enhance the contact reaction efficiency of oxygen and copper powder.

[0035] like Figure 2 , Figure 3As shown, in this embodiment, the valve core 4 includes a conical guide section 41 and a clamping portion 42 located at the bottom of the conical guide section 41. The conical guide section 41 is located inside the reaction tank body 1, and the clamping portion 42 is used to clamp with the discharge port of the reaction tank body 1, so as to close or open the discharge port. In addition, the bottom surface of the opening of the air cavity 12 is a straight section, and the straight section is smoothly connected with the conical guide section 41 at the top of the valve core 4. When the valve core 4 and the discharge port of the reaction tank body 1 are in a closed state, the conical guide section 41 can guide the gas ejected from the opening of the air cavity 12 upward. At the same time, the special shape of the reaction tank body 1, which is small at the top and large at the bottom, is also conducive to the distribution and rolling of copper powder or copper oxide powder along the set direction, which is not only conducive to the complete reaction of copper powder and oxygen, but also can avoid the agglomeration of copper powder, so that the copper powder remains dry, improves the utilization rate of copper powder, and avoids the accumulation of copper powder or copper oxide powder at the discharge port, thereby preventing the reduction of copper oxide generation efficiency.

[0036] The copper oxide preparation device of the utility model has a simple structure and can reduce production costs. The copper powder feeding bin 21 is connected to the reaction tank body 1 through the feed pipe 22. The driving component drives the valve core 4 to move up and down along the axial direction of the discharge port of the reaction tank body 1 to close or open the discharge port. That is, the utility model can generate and supply copper oxide in a timely manner according to the requirements of the copper dissolving system at any time, has high flexibility, and reduces the pressure of copper oxide powder logistics and storage.
