Microwave equipment capable of continuously smelting metal powder

Abstract

The invention discloses microwave equipment capable of continuously smelting metal powder. A microwave cavity of a microwave furnace is of an odd-number-hedron metal structure with no less than five planes; a microwave generator is installed on each of the side walls of the microwave cavity; the microwave generators are connected with a power source system through controlling units; a smelting crucible is installed in the microwave cavity; a temperature detection device is installed at the top of the microwave cavity; the temperature detection device extends to the smelting crucible and is connected with the controlling units in a signal mode; a conveying pipe communicating with a discharging port of a spiral feeder is installed on the smelting crucible; a feeding port of the spiral feeder communicates with a carrying bin; the carrying bin is of a closed bin capable of being opened and closed and communicates with an air supplying pipe of an atmosphere protection system; an unloading port is formed in the bottom of the smelting crucible and communicates with an overflow channel in the lower portion of the smelting crucible; a pouring trough is formed in the lower portion of the overflow channel, and the edge of the pouring trough is larger than that of the overflow channel; a pouring port is formed in the bottom of the pouring trough; a pouring control valve is installed on the pouring port; and an ingot casting machine is installed at the lower end of the pouring port. The microwave equipment capable of continuously smelting the metal powder has the characteristics that the production efficiency is high, energy consumption is low, the metal recovery rate is low, and the application range is wide.

Description

technical field

[0001] The invention belongs to the technical field of industrial furnaces, and in particular relates to a microwave equipment for continuously melting metal powder with high production efficiency, low energy consumption, high metal recovery rate and wide application range. Background technique

[0002] With the continuous development of science and technology, metal powder and its composite materials have shown extremely important application value in metallurgy, chemical industry, light industry, electronics, national defense, nuclear technology, aerospace and other research fields. The preparation methods of metal powder are increasingly abundant, ranging from ball milling, jet milling in mechanical methods to atomization, reduction and electrodeposition in physical and chemical methods, but there are a large number of methods in these preparation methods. Unqualified products need to be remelted. Taking the production of soldering tin powder by the rotary...
