Description

Technical Field

[0001] The utility model relates to the technical field of feeding materials for ore dressing agents, in particular to a raw material feeding structure for ore dressing agents. Background Art

[0002] Ore dressing agents mainly refer to collectors, foaming agents, inhibitors, flocculants, regulators, and extractants, matrix improvers for extraction, diluents, etc. used in hydrometallurgy, involving hundreds of inorganic or organic synthetic substances. Among them, there are 24 kinds of ore dressing agents listed in the blacklist of priority controlled pollutants in my country's water, and chemical agents harmful to the environment include cyanide, hydrogen sulfide, phosphine, fluoride, arsenide, dichromate, copper sulfate, zinc sulfate, carbon disulfide, sulfurous acid, various alkyl xanthates, organic phosphorus, fatty alcohols, aniline, pyridine, hydrocarbons, alkenes, ethers, ketones, aldehydes and esters, etc.

[0003] For example, the authorization announcement number "CN219816154U" is named a raw material feeding structure for mineral processing reagents. Although the servo motor drives the rotation of the driving shaft, turntable, chassis and driving column, so as to facilitate the alignment of the lower discharge holes with the upper discharge holes one by one, and thus facilitate the switching, so as to add the raw materials one by one into the mineral processing reagent preparation tank, but the existing raw material feeding structure for mineral processing reagents needs to pour a variety of different mineral processing reagent raw materials into different partitions of the barrel respectively, but the properties of the mineral processing reagent raw materials are quite different, so the mineral processing The raw materials of the reagents have different consistencies and fluidities. Therefore, when the baffle plate below rotates to add materials one by one, the time reserved for the raw materials to flow down through the discharge hole is consistent. As a result, the amount of raw materials with poor fluidity added is much less than that of raw materials with good fluidity. Therefore, the final frequency-adjusted mineral processing reagent mix ratio may not meet the standards. Not only that, the mineral processing reagent materials with higher viscosity will adhere to the inner wall of the barrel, which will be difficult to clean over time and will also cause a slow feeding speed inside the barrel, ultimately affecting the use effect of the raw material feeding structure of the mineral processing reagent.

[0004] At the same time, the existing raw material feeding structure of mineral processing reagents adopts the method of directly adding a variety of mineral processing reagent raw materials into the bottom of the barrel, and directly relying on the fluidity between various reagents for mixing and proportioning, lacking a stirring and mixing structure. Therefore, it is difficult for some reagents to fully react with each other, and raw materials will have residual and excessive slag problems, which not only causes waste of materials, but also reduces the quality of subsequent mixed mineral processing reagents, affecting the working quality of the raw material feeding structure of the mineral processing reagents.
