Embodiment Construction

[0017] see figure 1 , a quartz sand flotation process, is characterized in that: the quartz sand raw material is loaded into the production silo by the loader, and then the quartz sand raw material is sent into the mixing impeller by the electronic belt feeder and the belt conveyor. In the first mixing tank, a permanent magnet is placed outside the first mixing tank. Before the quartz sand raw material is sent into the first mixing tank, the first step of iron removal is carried out by the permanent magnet. The first mixing tank is added with 4 -5%H 2 SO 4 solution or 4-5% H 2 SO 4 and HF solution, adjust the PH value in the first mixing tank to 3, and send the quartz sand raw material to form a quartz sand slurry; then send the quartz sand slurry into the second mixing tank that has been treated with the mixing impeller. At the same time, add the flotation agent to the second mixing tank for stirring, so that the quartz sand slurry and the flotation agent fully react unti...

Abstract

The invention discloses a floatation process of quartz sand, comprising the following steps: feeding the quartz sand into a first conditioning barrel by an electronic belt feeder and a belt conveyor; adding H2SO4 solution or H2SO4 and HF solution after deironing to form quartz sand slurry; feeding the slurry into a second conditioning barrel, adding floatation medicament in the second conditioning barrel for full reaction; placing the slurry into a flotation machine for flotation, sieving the floated fine quartz sand through a polyurethane high-frequency sieve to flow into a fine sand tank; placing the fine quartz sand into an upper-layer desliming bucket through a slurry pump to remove large amount of moisture and placing into a lower-layer desliming bucket to add clean water for cleaning the fine sand, and then placing the fine sand into a dewatering base after deironing again. The floatation process of quartz sand is easy to realize and simple to operate, can rapidly and effectively realize flotation of quartz sand, improves the production efficiency of the quartz sand, greatly reduces the production cost of the quartz sand and reduces the labor intensity of operators as well.

Description

technical field [0001] The invention relates to the field of glass production, in particular to the field of quartz sand flotation technology. Background technique [0002] Ultra-white glass requires Fe in its composition 2 o 3 <0.009%, with high light transmittance, the light transmittance determines the quality of glass, the light transmittance of float glass is 86%, and the light transmittance of ultra-clear glass can reach more than 92%, the glass substrate of solar photovoltaic power generation system You need to use ultra-clear glass. The production of ultra-clear glass has particularly strict requirements on quartz sand, the most used raw material, SiO 2 >99.6%, Fe 2 o 3 <0.0050%±0.0010%, otherwise it cannot be guaranteed that Fe in the composition of ultra-clear glass 2 o 3 <0.009%. With the development of photovoltaic power generation, the demand for ultra-clear glass has increased several times, and the consumption of high-purity low-iron quartz...
