Description

Technical Field

[0001] The utility model relates to the technical field of rare earth production, in particular to a fluorination furnace heating device for rare earth metal processing. Background Art

[0002] Anhydrous rare earth fluoride is an essential raw material for extracting rare earth metals. Its preparation methods are generally divided into two types: wet conversion and pyro conversion. Pyro conversion usually uses hydrogen fluoride (HF) gas to fluorinate rare earth oxide at high temperature. Since hydrogen fluoride gas is highly corrosive at high temperatures, a heating element cannot be set inside the closed inner wall of the fluorination furnace for direct heating. Instead, a silicon carbon rod or a resistance alloy (such as iron-chromium-aluminum alloy) is set between the inner wall of the fluorination furnace and the insulation layer as a heating element to indirectly heat the rare earth material in the furnace.

[0003] After searching, the Chinese patent publication number CN217083316U discloses a fluorination furnace heating device for rare earth metal processing, including an upper circular plate and a lower circular plate, a plurality of heating rods are evenly distributed on the circumference of the opposing surfaces of the upper circular plate and the lower circular plate, a plurality of electric connectors electrically connected to the heating rods are provided at the bottom of the lower circular plate, a heating cavity is left between the insulation layer and the inner wall of the fluorination furnace body, a socket corresponding to the electric connector and an electric socket are provided inside the bottom wall of the fluorination furnace body, the upper circular plate and the lower circular plate are inserted into the heating cavity, and the electric connector passes through the socket and is inserted into the electric socket, an air inlet pipe is provided at the top of one side of the heating cavity, an air outlet pipe is provided at the bottom of the other side of the heating cavity, valves are provided on the air inlet pipe and the air outlet pipe, and a hot and cold blower is connected to the air inlet pipe, a sealing mechanism is provided between the upper circular plate and the fluorination furnace body, and a fixing mechanism is provided between the sealing mechanism and the fluorination furnace body. The above patent has the following shortcomings: although the patent can heat the rare earth inside the furnace through the heating rod set inside the furnace body and perform a fluorination reaction on the rare earth by heating, it is impossible to sample and observe the rare earth in the furnace body during the heating process, so it is impossible to detect the processing progress of the rare earth in real time. In view of this, we propose a fluorination furnace heating device for rare earth metal processing. Utility Model Content
