Description

Technical Field

[0001] The utility model relates to the technical field of quartz sand processing equipment, in particular to a device for recycling pickling waste liquid for high-purity quartz sand processing. Background Art

[0002] Quartz sand pickling liquid is a treatment liquid used for wet pickling of quartz sand, mainly containing hydrochloric acid, sulfuric acid, oxalic acid or hydrofluoric acid. The main purpose of this pickling process is to remove undesirable components such as iron oxides, other oxides and acid-soluble impurities on the surface of quartz sand. Specifically, impurities such as iron oxide can be removed by chemical reaction with acid, thereby improving the purity of quartz sand. If the quartz sand pickling liquid is directly discharged after one treatment, it will cause a large amount of pickling liquid waste, and cause a certain degree of pollution to the environment, greatly increasing the production cost.

[0003] The prior art also has the following defects during use:

[0004] 1. The treatment of pickling waste liquid in the prior art is relatively simple, but the simple treatment cannot effectively remove some impurities in the pickling liquid. If the impurities in the pickling liquid cannot be effectively removed and the pickling liquid is directly recycled, it will cause certain adverse effects on the pickling treatment of quartz sand, affecting the overall work efficiency;

[0005] 2. In the prior art, the treatment of pickling waste liquid may require zoning treatment. A device that can divert the pickling waste liquid between different areas is required for treatment and transportation. If diversion is not performed, when faced with a large amount of pickling waste liquid, it may cause accumulation and other problems, resulting in the treatment of the pickling waste liquid failing to achieve the expected goal.

[0006] In view of this, we propose a high-purity quartz sand processing pickling waste liquid recycling device to solve the existing problems. Utility Model Content
