Embodiment 1

[0034] Such as Figure 1~3 As shown, the invention discloses a quartz sand pickling device. In a specific embodiment of the invention, it includes a pickling bed 1 with a cavity 2 for placing quartz sand, and the upper end of the pickling bed 1 is detachable. A sealing cover 3 that can seal the cavity 2 is connected; one side of the pickling bed 1 is provided with a pickling device for delivering acid liquid from the bottom of the cavity 2 to the bottom of the quartz sand and a device for delivering compressed air into the cavity 2 The gas supply device is used to supply gas from the upper or lower end of the pickling bed 1 to the cavity 2; it also includes a water supply device used to deliver pure water to the bottom of the quartz sand.

[0035] In the present invention, the acid solution adopts mixed acid, and the components of the mixed acid are: 1-10% hydrofluoric acid, 1-15% hydrochloric acid, 1-15% nitric acid, and the reaction between hydrofluoric acid and quartz sand ...

Embodiment 2

[0048] Such as Figure 4 and Figure 5 As shown, the difference between this embodiment and the above embodiment is that in this embodiment, a gas dispersion device 15 is provided at the bottom of the cavity 2 of the pickling bed 1, and the gas dispersion device 15 is connected to the second gas supply pipe 12, the gas dispersing device 15 includes a horizontal plate 151 horizontally arranged in the pickling bed 1 and several evenly arranged partition columns 152 arranged at the bottom of the cavity 2 of the pickling bed 1. The upper and lower sides of each partition column 152 The ends are fixedly connected with the horizontal plate 151 and the bottom wall of the pickling bed 1 respectively. The distance between the partition columns 152 is equal and an exhaust channel 153 is formed between the partition columns 152. The upper ends of the horizontal plates 151 are provided with exhaust channels at intervals. Plate 154, the exhaust plate 154 is fixed in the pickling bed 1, an...

Abstract

The invention discloses a quartz sand pickling method and device. According to the technical scheme of the quartz sand pickling method and device, the quartz sand pickling device comprises a picklingbed with a cavity used for containing quartz sand, and a sealing cover capable of sealing the cavity is detachably connected to the upper end of the pickling bed; a pickling unit for conveying acid liquor to the bottom of the quartz sand from the lower part of the cavity and an air supply device for conveying compressed air into the cavity are arranged on one side of the pickling bed; the air supply device is used for supplying air into the cavity from the upper end or the lower end of the pickling bed; and the quartz sand pickling device also includes a water supply device used for conveyingpure water to the bottom of the quartz sand. The invention has the beneficial effects that acid liquor and quartz sand are fully mixed, the pickling effect is good, less cleaning water is used, the cleaning time is short, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of quartz sand purification, in particular to a quartz sand pickling method and device. Background technique [0002] Quartz sand is a very important non-metallic mineral raw material, which is widely used in industries such as glass, ceramics, cement and refractory materials; the grade and value of quartz sand mainly depend on the content of metal impurities in the quartz sand itself, especially The content of metal minerals represented by impurity iron determines the value and use value of quartz sand. [0003] Pickling of quartz sand is mainly to improve the purity of quartz sand, the mixed acid reacts with metal impurities in quartz sand, washes them off, and reduces the content of metal impurities in quartz sand; at present, the method of soaking is mainly used, and the pickling reaction is slow and takes a long time. It is because pickling is not sufficient, and the ideal effect cannot be achieved; at...
