Equipment for continuously producing scheelite ore concentrate with microwave method

Abstract

The invention provides equipment for continuously producing scheelite ore concentrate with a microwave method. The equipment comprises a furnace body bracket and a furnace body, wherein an air suction opening is formed in the furnace body; the equipment further comprises a microwave emission energy feedback device and a microwave power supply, a microwave energy feedback water cooling device, an inner calcining material heat preservation layer and a fireproof material, a microwave inhibiting shielding device, an automatic rotary discharging mechanism, an automatic material weighing and charging device, an outer circulation roller bed movement system, a longitudinal pneumatic execution material pushing air cylinder, a transverse pneumatic execution material pushing air cylinder, a steering pneumatic execution material pushing air cylinder, a temperature measuring device and an electric control device. According to the equipment for continuously producing the scheelite ore concentrate with the microwave method provided by the invention, microwave energy is directly converted into heat of a product by using a high-frequency-band working property of microwaves, and the heat is uniformly conducted to the outer part from the inner part of the product and is rapidly dispersed, so that the whole temperature of the product is rapidly raised; compared with a traditional electric furnace, the temperature of the treated material is rapidly raised, the temperature gradient is uniform, the energy consumption is small, continuous and stable production is realized, the desulfurization effect is good and the grade is high.

Description

technical field [0001] The invention relates to the technical field of tungsten ore materials, in particular to equipment for continuously producing scheelite concentrate and other tungsten ore by microwave method. Background technique [0002] Scheelite is a kind of ore, white with yellow, tetragonal crystal system is the main raw material for smelting tungsten, the main producing areas are Yaogangxian, Hunan, China, which is a world-famous scheelite ore producing area; other main producing areas in the world are: Saxony, Germany, Conn, UK Wall, Australia, North Korea, the United States, etc. Application: 80% of scheelite mined in the world is used for smelting high-quality steel, 15% is used for producing hard steel, and 5% is used for other purposes. Scheelite can be used to make firearms, nozzles for rocket propulsion, and cut metals. It is a metal with a wide range of uses. The pure metal form and alloy state of scheelite are widely used in modern industry. The most i...
