Description

Technical Field

[0001] The invention relates to the technical field of silicon dioxide, in particular to a recovery and treatment device for quartz sand pickling liquid. Background Art

[0002] The main component of quartz sand is silicon dioxide. During the purification process of quartz sand, it is necessary to remove some acid-soluble metal oxides and some silicate minerals through pickling. Hydrofluoric acid pickling is mainly used for purification. During the pickling process, hydrofluoric acid reacts with quartz sand to generate fluorosilicic acid. If it is not treated, direct discharge will not only cause serious environmental pollution, but also the fluorosilicates formed by fluorosilicic acid can be usually used for wood preservation, ceramic manufacturing, aluminum and magnesium smelting, agricultural pesticides, optical glass manufacturing, mica formation, and production of ceramic industrial glazes, porcelain paints, enamel products, etc. Failure to recycle and reuse them will cause great waste.

[0003] In the prior art, a search of Chinese patent application CN117049552A discloses a method for recovering fluorosilicate from high-purity quartz sand pickling wastewater; the method comprises the following steps: S1, pickling high-purity quartz sand with hydrofluoric acid (ultrapure); S2, filtering the pickling liquid after pickling to obtain fine quartz sand solid and fluorosilicic acid filtrate; S3, stirring, heating and concentrating the fluorosilicic acid filtrate, and continuously adding an inorganic alkali solution for sedimentation, and stopping adding the inorganic alkali solution when the pH value of the mixed solution is 7.2-7.5; and S4, filtering the mixed solution after sedimentation, collecting the filter cake and drying it to obtain fluorosilicate.

[0004] The above scheme is to place the fluorosilicic acid filtrate obtained after acid washing of quartz sand in a sedimentation tank, stir it, and continuously add an inorganic alkali solution to react with the fluorosilicic acid filtrate to continuously precipitate crystals containing fluorosilicate. However, in the process of continuously adding the inorganic alkali solution into the fluorosilicic acid filtrate, crystals containing fluorosilicate will continuously precipitate inside the sedimentation tank, which will easily affect the reaction of the subsequently added inorganic alkali solution with the fluorosilicic acid filtrate, thereby reducing the precipitation rate of the crystals containing fluorosilicate.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] As introduced in the background technology, in order to solve the deficiencies existing in the prior art and the above technical problems, the present application proposes a recycling and processing device for quartz sand pickling liquid.

[0037] When in use, the feeding component 7 is connected to the fluorosilicic acid filtrate and the inorganic alkali solution through pipelines, so as to facilitate the addition of the fluorosilicic acid filtrate and the inorganic alkali solution into the sedimentation tank 1. The fluorosilicic acid filtrate is added into the sedimentation tank 1 in cooperation with the feeding component 7, and then the driving component 3 is started, which can drive the stirring component 2 fixedly installed at its output end to rotate, so that the stirring component 2 can stir the fluorosilicic acid filtrate, and then the inorganic alkali solution is continuously added into the sedimentation tank 1 through the feeding component 7. When the inorganic alkali solution contacts the fluorosilicic acid filtrate, it can cause a reaction and precipitate crystals containing fluorosilicates. Then, the crystals containing fluorosilicates sunk to the bottom of the sedimentation tank 1 can be pushed upward in cooperation with the stirring component 2 and made to fall on the top of the collecting component 5. Since the outer surface of the collecting component 5 It is fixedly mounted on the outer surface of the stirring component 2, and when the stirring component 2 rotates, it can drive the collecting component 5 to push the crystals containing fluorosilicate on its surface to one side of the lifting component 6 and make them enter the interior of the lifting component 6. Since the outer surface of the lifting component 6 is fixedly mounted on the interior of the transmission component 4, and the interior of the transmission component 4 is fixedly mounted on the output end of the driving component 3, when the driving component 3 is started, it can cooperate with the transmission component 4 to drive the lifting component 6 to rotate.

At the same time, the driving component 3 can drive the transmission component 4 fixedly installed at its output end to rotate. When the transmission component 4 rotates, it can drive the lifting component 6 fixedly installed inside it to rotate.
