Silica processing pretreatment device

Abstract

The invention relates to the field of ore, in particular to a silica processing pretreatment device. The technical problem is to provide the silica processing pretreatment device. According to the technical scheme, the silica processing pretreatment device comprises a bottom frame, a supporting frame, a control display screen, a stepping motor, an edge grinding mechanism, a color system sorting mechanism, a film layer removing mechanism and a storage bin, wherein and the bottom frame is welded with the supporting frame. The device has the effects that the edge grinding treatment is carried outon silica with sharp edges and corners in advance, so that the abrasion to a machine during further processing is avoided; and meanwhile, machine chippings are mixed into silica raw materials, and the reddish-brown silica with iron oxide films is sorted out through color discrimination to be washed with acid liquor, so that the waste of a large amount of acid liquor and low treatment effect caused by treatment on all the silica raw materials are avoided, the removal of the iron oxide films is beneficial to further processing on the silica raw materials, and the quality of silica products is improved.

Description

technical field [0001] The invention relates to the ore field, in particular to a silica processing pretreatment device. Background technique [0002] Silica is a general term for vein quartz, quartzite, and quartz sandstone. It is mainly used for acid refractory bricks used in metallurgical industry. Pure silica can be used as quartz glass or refined single crystal silicon. The appearance of crystalline silica is generally milky white, off-white, light yellow and reddish brown. It has bright luster, smooth and continuous section, with sharp edges and corners, and has great hardness and strength. Excellent silica should be in dense block shape, sometimes with shell-like or scaly section, without obvious layered structure, between layers and There are no inclusions between layers and no limestone crust. Its color depends on impurities. Usually, iron compounds make silica reddish brown, while organic impurities make silica gray or black. Contents of the invention [000...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the fact that most of the silica raw materials have sharp edges and corners, it is easy to cause great wear and tear on the machine when the silica is further processed, increasing unnecessary costs, and at the same time, debris generated by machine wear is also easy to mix It is difficult to remove from silica raw materials, and the iron oxide film on the surface of some silica reduces the refractoriness of silica products. At the same time, it wastes a lot of resources to process all silica raw materials, and the processing effect is low, and the ideal effect cannot be achieved.
