Quartz sand mining area tailings recovery treatment device

Abstract

The invention belongs to the technical field of quartz sand recovery, and particularly relates to a quartz sand mining area tailings recovery treatment device. The device comprises a U-shaped pipe, afeeding hopper, a receiving hopper, a water spraying pipe, water passing holes and a flushing pipe; the receiving hopper is arranged at one end of the U-shaped pipe; the feeding hopper is arranged above the receiving hopper; a water spraying hole is formed in a discharging hole in the bottom of the receiving hopper; the diameter of the discharging hole is larger than that of the water spraying hole; the water spraying hole communicates with a water source through the water spraying pipe and a water pump; the bottom of the U-shaped pipe is positioned in the concentric square-shaped flushing pipe; circulating water flows in the flushing pipe; and a group of the water passing holes are formed in the part, located inside the flushing pipe, of the U-shaped pipe. According to the device, soil adhered to quartz sand is flushed through water flow sprayed by the water spraying hole; and when suspension liquid formed by the soil, the quartz sand and water flows through the bottom of the U-shapedpipe, and the circulating water in the flushing pipe flows through the water passing holes to take away slurry containing the soil so as to well separate the soil from the quartz sand.

Description

technical field [0001] The invention belongs to the technical field of quartz sand recovery, in particular to a recovery treatment device for tailings in quartz sand mining areas. Background technique [0002] Quartz sand, also known as silica sand, is a common non-metallic mineral raw material with a wide range of applications. Quartz sand is mainly used in the construction industry, glass manufacturing, ceramic industry and foundry industry, which have a great demand for quartz sand. [0003] Domestically, high-purity quartz sand is mostly made of high-quality raw materials such as crystal and vein quartz ore. However, with the gradual depletion of high-quality mineral resources, the cost of high-purity quartz sand is high. At the same time, every ton of high-purity quartz sand is usually produced. It needs to consume 2.5 tons of quartz raw materials, resulting in 1.5 tons of tailings. At present, these tailings are generally discarded directly. This treatment method not ...

AI Technical Summary

Problems solved by technology

[0004] In order to make up for the deficiencies of the existing technology, to solve the waste of quartz sand resources when the quartz sand tailings are directly discarded, occupy a large amount of land, and also endanger the atmosphere through volatilization and dust, causing serious environmental pollution; there are more mud in the quartz sand tailings, And the quartz sand is wrapped with more iron oxide, which is not conducive to the problem of recycling. The invention proposes a tailings recovery and treatment device in the quartz sand mine area.
