Impurity removal and purification device for feldspar ceramic raw materials

Abstract

The invention discloses an impurity removal and purification device for feldspar ceramic raw materials. The impurity removal and purification device comprises an outer cylinder and an inner cylinder, the inner cylinder is rotationally arranged in the axis of the outer cylinder, a rotating mechanism is arranged at the outer end of the outer cylinder, a material cavity is formed in the area between the outer wall of the inner cylinder and the inner wall of the outer cylinder, and a feeding port and a discharging port which are communicated with the two ends of the material cavity are formed in the two ends of the side wall of the outer cylinder correspondingly; a material pushing spiral blade is spirally fixed on the outer wall of the inner cylinder, the outer edge of the material pushing spiral blade is in sliding connection with the inner wall of the outer cylinder and divides the material cavity into a spiral channel, a plurality of electromagnets used for adsorbing magnetic impurities in the material cavity are installed on the inner wall of the inner cylinder, and a material turning mechanism used for turning raw materials in the material cavity is arranged between the inner wall of the outer cylinder and the outer wall of the inner cylinder; and the magnetic adsorption process of the raw materials can be effectively improved through the spiral material pushing adsorption magnetic channel, magnetic impurities are removed while the passing ability of the raw materials is guaranteed, the raw materials are fully adsorbed through the material overturning mechanism, and the impurity removal process is rapid and environmentally friendly.

Description

Technical field [0001] The present invention generally relates to a long stone ceramic raw material deduction device, and is specifically a long stone ceramic feedstock to pure means. Background technique [0002] Changshi is a raw material for ceramic products. Although the longshine resources are rich, it is really satisfied that the industrial requirements are limited, and most of them contain harmful elements such as iron and titanium, and the longtestant mohater is generally contain quartz, white clouds. Minerals such as mother, black, and corner, it is also because of the existence of these substances, causing the long stone burning in whiteness to meet industrial requirements, and therefore, these magazines must be removed from the original mine, so that they meet certain indicators, increase ore utilization Value, meet industrial requirements. [0003] Weak magnetic minerals such as iron oxide (browning, hematite), mica, pomegranate stone, etc. in terctorate, the magnetic...

Problems solved by technology

[0002] Feldspar is a raw material for ceramic products. Although feldspar is rich in resources, there are limited high-quality ores that can really meet industrial requirements. Most of them contain harmful elements such as iron and titanium. Feldspar ores generally contain quartz, dolomite, etc. It is also because of the existence of these substances that the whiteness of feldspar does not meet the industrial requirements. Therefore, these impurities must be removed from the raw ore to make it meet certain indicators and increase the utilization of the ore. value, meeting industrial requirements

[0003] Weak magnetic minerals such as iron oxides (limonite, hematite), mica, and garnet in feldspar are generally screened by magnetic means, and feldspar ore is generally made into powder by crushing devices such as ball mills before screening. For granular raw materials, the raw materials are passed into the magnetic separator for magnetic separation. The current magnetic separator is equipped with a fixed electromagnet in the raw material channel to absorb the magnetic impurities in the raw materials when the raw materials pass through. The electromagnet is powered off, and then the impurity is removed by washing with water. Due to a single magnetic separation, the raw material layer is thick or cannot be completely absorbed. The general impurity removal production line will be equipped with multi-stage magnetic machines for screening, or the current more efficient multi-stage Gradient magnetic separators perform gradient sorting, but all have poor single-shot magnetic effects, magnetic impurities in raw materials cannot be fully dispersed, adsorbed and discharged, the overall screening production line layout costs are high, and there are environmental issues such as sewage treatment during the impurity removal process
