Embodiment

[0052] Embodiment: A kind of 10KA level rare earth electrolyzer structure, its construction technology comprises the following steps:

[0053] Step 1. Take the pretreated tank shell 1, lay a layer of aluminum silicate fiber felt (fiber insulation layer 2) with a thickness of 2-4cm on the inner wall of the tank shell 1, and then use diatom mud insulation bricks (Refer to specification 230×115×65mm) Insulation layer 3 with a bottom thickness of 30-35cm and a side wall thickness of 20-25cm requires staggered gaps between each layer of bricks;

[0054] Step 2. Spread a layer of heat insulation layer 4 with a thickness of 6.5cm on the end face of the insulation layer 3 with clay refractory bricks (reference specification 230×115×65mm). Lay and compact a layer of magnesia material with a thickness of 5-10cm on the layer 4 to form the first refractory layer 5. There is a φ25mm PVC pipe (i.e. exhaust pipe), and then the first steel sleeve (i.e. the first metal sleeve 6) is placed on ...

Abstract

The invention discloses a construction technology of a 10KA-level rare earth electrolysis cell. The technology comprises following steps: step 1, a thermal insulating layer is laid on the inner wall of a cell casing; step 2, a first refractory layer is laid above the thermal insulating layer, and a first metal sleeve is arranged above the first refractory layer; step 3, a second metal sleeve is arranged in the first metal sleeve; step 4, an electrolysis cell is put in the second metal sleeve; step 5, a corundum gasket is laid at an opening of the electrolysis cell; step 6, a furnace table board is mounted at the top of the electrolysis cell, and an anode is fixedly mounted on the furnace table board; step 7, a crucible is mounted at the bottom of the electrolysis cell. According to the construction technology of the electrolysis cell, the electrolysis cell is tighter and firmer in structure, good in thermal-insulating and anti-seep effect and high in structural stability and has the characteristics of high output, low energy consumption, long service life, low unit consumption of raw materials, high yield and the like, current of the electrolysis cell is 10KA or higher, and the problems of a conventional electrolysis cell are solved.

Description

technical field [0001] The invention relates to the field of rare earth electrolytic cell structure, in particular to a construction technique of a 10KA level rare earth electrolytic cell. Background technique [0002] Rare earth elements are known as "industrial vitamins" and are widely used in petroleum, chemical, metallurgy, textile, ceramics, glass, permanent magnet materials and other fields. With the advancement of science and technology and the continuous breakthrough of application technology, the value of rare earth and its related products will increase. [0003] With the continuous advancement of rare earth metal smelting technology and the continuous development and expansion of the industry, the technology of preparing rare earth metals and alloys by molten salt electrolysis has also made great progress. Before the 1980s, it was mostly a chloride molten salt electrolysis process. The scale of the electrolytic cell was usually 2000-3000A, the yield was less than...
