Description

Technical Field

[0001] The utility model relates to the field of lead-zinc ore processing, in particular to an environment-friendly flotation device for lead-zinc ore. Background Technique

[0002] In the process of processing and smelting lead-zinc ore, a large amount of zinc scum will be produced in hydrometallurgical zinc smelting. To ensure that the zinc scum can meet environmental protection standards, a flotation device is usually used to float the lead sulfate in the zinc scum. To ensure the flotation capture effect, benzohydroxamic acid will be added during flotation. Because benzohydroxamic acid has a strong collecting ability for lead oxide ores such as lead sulfate, the potentiometric and infrared spectroscopy can be used to analyze and study its action mechanism. It can be proved that the reaction between benzohydroxamic acid and lead sulfate has undergone chemical adsorption. Because the lead ions on the surface of lead sulfate react with benzohydroxamic acid to form a stable chelate, the phenyl group is hydrophobic and plays a collecting role.

[0003] Chinese Patent with publication number CN215429619U discloses an environment-friendly flotation device for lead-zinc ore. Through the arranged connecting pipe and dispersion ring pipe, the air in the driving pipe can be dispersed and quickly distributed in the pulp under the rotation of the driving pipe, changing the original phenomenon that the air is introduced into the pulp in a concentrated manner, resulting in an extended time for the air to be fully distributed in the pulp and thus affecting the flotation efficiency. In this way, its flotation efficiency is improved. At the same time, under the action of the shovel plate, the slag deposited at the bottom of the barrel can be scraped up to float in the water, so as to avoid the phenomenon that the flotation quality decreases due to slag precipitation, and thus improve its flotation quality. And under the action of the pressing part, the shovel plate can always be in contact with the bottom of the barrel. However, during the process of stirring and scraping the slag by using the stirring blade and the shovel plate in the flotation device of this patent, a large amount of slag impurities are easily adhered to the stirring frame and the bottom scraper. The stirring mechanism in the patent is relatively fixedly connected to the device body and is not convenient for disassembly and cleaning. When cleaning is required, it is more troublesome for the staff to enter the inside of the body. At the same time, when the existing technology passes air into the slag, there is no filtration, resulting in some other substances in the air mixing into the slag and affecting the flotation result.

[0004] Therefore, the utility model provides an environment-friendly flotation device for lead-zinc ore to solve the above problems. Content of the Utility Model

[0034] The present invention provides an environmentally friendly flotation device for lead-zinc ore, as Figures 1-4As shown in the figure, the environmental protection flotation device for lead-zinc ore includes a material cylinder 1, a bracket 11 fixedly arranged at the bottom of the material cylinder 1, a foam discharge pipe 12 fixedly arranged at a position near the top on the side of the material cylinder 1, a slurry discharge pipe 13 communicated with the side of the material cylinder 1, and a foam scraping plate 121 hinged to the inner wall of the material cylinder 1 on the side close to the foam discharge pipe 12. It also includes a stirring mechanism 2 axially moving in the material cylinder 1 and a first driving mechanism 3 located on one side of the material cylinder 1 for driving the stirring mechanism 2 to move.

Among them, the rotating shaft 22 includes a driving shaft 221 rotatably installed on the support frame 21, a stirring shaft 222 fixedly installed on the support ring 23, and a connecting structure 223 for fixing the stirring shaft 222 on the driving shaft 221.

[0035] During use, by injecting water containing benzohydroxamic acid into the material cylinder 1 and putting slag into the material cylinder 1, the user uses the second driving mechanism 24 to drive the rotating shaft 22 to rotate, thereby driving the driving shaft 221 and the bottom stirring shaft 222 to stir the water and slag. At the same time, the support ring 23 at the bottom of the stirring shaft 222 scrapes up the slag at the bottom of the material cylinder 1, and the stirring rods 231 make the internal substances more fully stirred, then a large amount of foam is generated. The generated foam is scraped off by the foam scraping plate 121 and discharged through the foam discharge pipe 12 to complete flotation. After flotation, the water flow in the material cylinder 1 is discharged along the slurry discharge pipe 13, thus completing the whole use. During the flotation process, in order to avoid the problem that a large amount of slag impurities are easily adhered to the support ring 23 during the process of using the rotating shaft 22 to stir and scrape the slag, which is not convenient for disassembly and cleaning, the whole rotating shaft 22 can be lifted upward by using the first driving mechanism 3, and then the bottom stirring shaft 222 can be disassembled by using the connecting structure 223 to achieve the effect of convenient cleaning.

When disassembly and cleaning are required, the rotating block 2235 can be manually rotated to a position where it coincides with the fixing rod 2234. At this time, due to the influence of automatic gravity, it is convenient to remove the entire fixing rod 2234 and the second mounting ring 2232, which is convenient for splitting the first mounting ring 2231 and the second mounting ring 2232, and then completing the splitting of the stirring shaft 222 for easy removal and cleaning. After cleaning, it is reinstalled, the first mounting ring 2231 and the second mounting ring 2232 are spliced, and then the fixing rod 2234 is inserted along the bottom fixing slot 2233.
