Problems solved by technology

[0003] There are various methods of preparing metal powder, among which electrolysis is a commonly used metal powder processing method. The negative pole and positive pole are put into the metal salt solution through the electrification, and the positive metal ions will move to the negative pole and generate electrons with the negative pole. reaction, and then get the metal powder and attach it to the negative pole. For some extremely active metals, the metal powder cannot be obtained by electrolysis of the metal salt solution, and most of them will get the hydroxide of the metal. Therefore, for this kind of metal, most of them will use molten salt It is prepared by electrolysis, especially some rare metals such as thorium, niobium, zirconium and tantalum are mostly prepared by molten salt electrolysis. In the powder metallurgy industry, sometimes it is necessary to mix and process various metal powders, which needs to be processed in the subsequent process. In the process of mixing the metal powder again, it takes a lot of manpower and material resources

Abstract

The invention relates to a molten salt electrolysis device for preparing mixed metal powder. The molten salt electrolysis device comprises an electrolysis box and an electrolysis rack; an anode bar and a cathode bar which are connected to a power supply and vertically penetrate into the electrolysis box are arranged at the lower part of the electrolysis rack; the electrolysis box is a cavity without an upper cover or a lower bottom and is arranged in an electrolytic cell seat; a protective sleeve which is inserted into the electrolysis box and is in sealing fit with the electrolysis box is arranged at the inner bottom surface of the electrolytic cell seat; an electric heating block is arranged in the protective sleeve; a hot melting feeding port is formed in the electrolysis rack; the lower part of the electrolysis rack is connected with a hot melt feeding tube; an auger propeller which is in the vertical direction is arranged at the upper part of the hot melting feeding port; the sidepart of the auger propeller is connected with not less than two hot melting devices arranged on the electrolysis rack through hot melting discharge tubes; and a discharge control valve is arranged oneach hot melting discharge tube. The purpose that metal hot molten salts are uniformly mixed proportionally and enter the electrolysis box can be achieved, and the effect that mixing of metal can becompleted when molten salt electrolysis is carried out for preparing the metal powder can be further realized.

Description

technical field [0001] The invention relates to the field of metal powder processing equipment, in particular to a molten salt electrolysis device for preparing mixed metal powder. Background technique [0002] Metal powder refers to a group of metal particles whose size is less than 1 mm. Including single metal powder, alloy powder and some refractory compound powder with metallic properties, it is the main raw material of powder metallurgy. [0003] There are various methods of preparing metal powder, among which electrolysis is a commonly used metal powder processing method. The negative pole and positive pole are put into the metal salt solution through the electrification, and the positive metal ions will move to the negative pole and generate electrons with the negative pole. reaction, and then get the metal powder and attach it to the negative pole. For some extremely active metals, the metal powder cannot be obtained by electrolysis of the metal salt solution, and m...
