The invention relates to a foreign matter isolating device and particularly relates to a foreign matter isolating device for an alumina storage bin of a large or super large diameter of 18 meters. In the foreign matter isolating device for the alumina storage bin, a frame beam is arranged under a discharge hole at the top of the storage bin; steel I-beams are arranged in the frame beam, two ends of each steel I-beam are fixed on the frame beam, and a steel barrier is arranged between each two adjacent steel I-beams. The foreign matter isolating device can keep foreign matters such as refractory brick blocks, concrete fragments, package bags and PVC thin films which are mixed in alumina powder during production above the barrier, ensure the normal use of the alumina powder in super dense phase conveyance, chute scales and volume fixing devices and reduce overhaul workload.
Description
technical field [0001] The present invention relates to a foreign matter isolation device, in particular to a large diameter or super large diameter aluminum oxide silo foreign matter isolation device with a diameter greater than 18m, a device for separating and isolating various foreign matters mixed with alumina powder in the alumina production process . Background technique [0002] In the production process of electrolytic aluminum, the aluminum oxide powder is often mixed with refractory bricks, concrete fragments, packaging paper bags, PVC film fragments, metal wires, wire balls and other sundries, which will cause the blockage of the ultra-dense phase chute, affecting the measurement scale, The normal operation of the fixed container may even affect the product grade of the molten aluminum. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention provides a foreign matter isolation device for alumina silos, ...
