Description

Technical Field

[0001] This utility model relates to the technical field of mineral smelting material preparation equipment, and more specifically, to a preparation equipment for sodium hydroxamate. Background Technology

[0002] Sodium hydroxamate, as an important mineral smelting material, is widely used in the field of mineral processing, especially in the collection of metal oxides, where it exhibits excellent performance. The preparation method of sodium hydroxamate usually involves the hydroxamication reaction of salicylates and hydroxylamine sulfate under specific conditions, followed by solid-liquid separation to obtain the target product.

[0003] The preparation of sodium hydroxamate is usually carried out in a corresponding preparation equipment. There are many types of sodium hydroxamate preparation equipment on the market. Most of these preparation equipment first transports the material to the corresponding mixing equipment through corresponding pipelines or conveying components, and then the raw materials are mixed by the rotation of the stirring blades to achieve the effect of mixing and preparation reaction.

[0004] However, when using this type of equipment, it takes time to add a certain amount of material to the preparation equipment. When multiple materials are added sequentially to their respective devices and then mixed, a considerable amount of time is required. Furthermore, to ensure thorough and uniform mixing, a prolonged mixing time is necessary. This design lacks the ability to pre-mix multiple raw materials during material transport, which to some extent limits the reaction rate and may lead to uneven mixing, affecting the preparation effect. Therefore, we propose a preparation device for sodium hydroxamic acid. Utility Model Content
