Embodiment Construction
[0014] A method for preparing copper oxide powder, comprising the steps of:
[0015] Step 1. Heat the copper chloride solution and hydrogen gas and input the atomization nozzle to atomize the copper chloride solution droplets at the same time, so that the copper chloride solution is reduced by the hydrogen gas to generate copper powder and hydrochloric acid, and pass it into the circulating alkaline solution ; The heating temperature of copper chloride solution and hydrogen heating is 75-95°C;
[0016] Step 2, placing the copper powder in the circulating water flow, and then injecting heated oxygen-containing gas into the circulating water flow for oxidation to obtain copper oxide powder;
[0017] Step 3: Precipitate or filter to obtain copper oxide powder, dry it, and roast at a temperature above 190° C. to obtain a finished copper oxide powder.
[0018] Wherein, the temperature of the oxygen-containing gas introduced is 80-110°C. The oxygen-containing gas is oxygen or air....

The invention discloses a copper oxide powder manufacturing device which comprises an atomizing nozzle; one side of the atomizing nozzle is communicated with a copper chloride storage box through a solution pipe, and the other end of the atomizing nozzle is communicated with a hydrogen storage tank through a gas pipe; a solution pump and a first heater are mounted on the solution pipe; the gas pipe is provided with a gas pump and a second heating device; the atomizing nozzle is positioned at one end of a cylindrical tank body; one end of the cylindrical tank body is tangentially communicated with a gas inlet pipe; the gas inlet pipe is communicated with a gas pipe; the other end of the cylindrical tank body is communicated with an air outlet pipe along the tangential direction; the air outlet pipe is communicated with a columnar shell; a plurality of aeration holes which tilt outwards from the middle part are formed in the top of the columnar shell; the columnar shell is located in thecylindrical shell and is coaxial with the cylindrical shell; and the columnar shell is also communicated with an oxygen-containing gas inlet pipe. The copper oxide powder is prepared by adopting a two-step method, the problem that copper oxide is condensed into blocks due to the fact that copper oxide is prone to particle aggregation in the manufacturing process is effectively solved, and the manufacturing difficulty and the danger degree of copper oxide are greatly reduced.
Description
Technical field: [0001] The invention relates to the field of powder production, in particular to a production device for copper oxide powder. Background technique: [0002] The production of powder by gas atomization method is to mix and atomize the molten metal with gas to obtain oxide powder. Copper oxide has a wide range of uses. In addition to being used as a raw material for making copper salts, it is also widely used in electronic information products, such as mobile phones, computer-related products and other integrated circuits. The current copper oxide powder is usually mixed with oxygen after melting copper and sprayed through an atomizing nozzle to form copper oxide. However, its disadvantages are that copper needs to be melted at a high temperature above 1400°C, which leads to high energy consumption and high operational risk. Invention content: [0003] The object of the present invention is to provide a production device for copper oxide powder. The presen...
