Pressure- relief material returning treatment device and method

Abstract

The invention relates to the technical field of refractory material mixing, in particular to a pressure- relief material returning treatment device and method when refractory materials with various particle sizes are unloaded into a mixing machine. The device comprises an expansion bin, a resistance wire, an anti-blocking device, a bag-type dust collector and an induced draft fan, the expansion bin is arranged above a mixing device, the bottom is connected with a dust removal port of the mixing device, the top is connected with the bag-type dust collector through a dust removal pipeline, and the anti-blocking device is arranged on the outer side of the middle bin wall; the induced draft fan is connected with the bag-type dust collector, and the bottom of the bag-type dust collector is connected with the mixing device through a material returning pipeline; a resistance wire is wound on the outer side of the lower bin wall of the expansion bin and the outer side of the lower part of thereturn pipeline. The refractory material powder can be automatically recycled and returned to the mixing device, so that the recycling of raw materials is realized; meanwhile, the labor intensity of workers is reduced; dust pollution during transferring is avoided, and the working environment of refractory material production is improved; the proportioning precision of all the raw materials in pugis improved, and the structure and performance of the product are improved.

Description

technical field [0001] The invention relates to the technical field of refractory material mixing, in particular to a device and method for processing pressure relief and return materials when refractory materials with various particle sizes are unloaded into a mixer. Background technique [0002] Refractory materials refer to materials whose physical and chemical properties allow them to be used in high-temperature environments. Driven by the rapid development of high-temperature industries such as steel, nonferrous metals, petrochemicals, and building materials, the refractory industry has maintained a good growth trend. China has become the world's refractory industry. A major producer and exporter of materials. However, due to disorderly mining, low level of processing technology, low level of comprehensive utilization of resources, and serious waste, mineral resources, especially high-grade refractory raw material resources, have become less and less. Saving resources a...

Problems solved by technology

However, refractory raw materials are generally expensive and have no waste. Only dust removal will cause waste of raw materials and affect the accuracy of material proportioning. Therefore, the above-mentioned part of the powder should be recycled and reused.
