Description

Technical Field

[0001] This invention relates to the field of hydrometallurgical technology, specifically to a lead-zinc smelting leaching reaction apparatus. Background Technology

[0002] Hydrometallurgy is a method in which ores, mineral concentrates, or other raw materials are contacted with aqueous solutions or other liquid phases. Through chemical reactions, the useful metals contained in the raw materials are transferred into the liquid phase. The various useful metals in the liquid phase are then separated and concentrated, and finally recovered as metals or other compounds. It mainly includes unit operations such as leaching, liquid-solid separation, solution purification, metal extraction from the solution, and wastewater treatment.

[0003] Bottom-blown furnace flue dust in lead smelting is rich in various recyclable metals. It can usually be extracted efficiently using wet leaching processes to extract valuable metals such as lead and zinc. However, conventional stirring equipment is mostly limited to transverse stirring mode and lacks effective flow field disturbance and breaking function, making it difficult to achieve effective dissociation and dispersion of clumps. In the process of mixing flue dust with leaching solution, flue dust agglomeration is prone to occur, which will cause the flue dust inside the clumps to not fully contact the solution, thereby reducing the metal recovery rate.

[0033] Working principle: Connect the feed inlet 303 to the external feeding pipe, connect the discharge connector 308 to the external discharge pipe, and connect the inlet pipe 215 to the external water pipe. In use, the mixing motor 310 is started, which drives the converter transmission cylinder 305 to rotate. The converter transmission cylinder 305 drives the transmission guide hollow shaft 101, causing the stirring rod 106, eccentric wheel 103, circulating centrifugal fan blade 102, and dissociation cutting wheel 104 to rotate. Then, the material and solution are fed in through the feed port 303. After the material is injected, most of the material mixes with the solution, and some agglomerated material clumps are intercepted on the surface of the dissociation screen 204. Due to the rotation of the circulating centrifugal fan blade 102, the centrifugal force generated by the rotation of the circulating centrifugal fan blade 102 propels the solution to flow outward, causing the solution above to continuously flow through the inlet hole 206 into the circulating centrifugal fan blade 102, and then flow upward along the circulation tank 202. After the solution flowing along the circulation tank 202 reaches the guide bend 210, it is guided by the guide plate 209 to flow towards the center. The liquid continuously washes against the dissociation screen 204, causing clumps on the surface of the screen to be cut into smaller clumps by the mesh openings. These clumps then move downwards along the solution through the screen 204 and are cut by the rotating dissociation cutting wheel 104. The clumps are then broken up after passing through the cutting groove 109. The solution is then pumped downwards by the circulating centrifugal fan 102 and re-enters the circulation tank 202, where residual clumps are cut by the dissociation screen 203. The circulating flow of the solution further breaks down the clumps until they are completely dispersed. When the eccentric wheel 103 rotates, its center of gravity shifts, causing radial vibration, which in turn causes the stirring rod 106 to vibrate. This vibration continuously strikes and breaks down the passing clumps as the stirring rod 106 rotates and mixes the material. During discharge, the negative pressure pump on the external discharge pipe is started, which generates negative pressure at one end of the discharge connector 308. Due to the attraction of the negative pressure and the pressure of the solution, the flow channel 406 slides upward and the bottom of the flow channel 406 opens. After being attracted by the negative pressure, the material passes through the wall-mounted guide membrane 402 and enters the interior of the flow channel 406. Then, it enters the converter drive cylinder 305 along the drive guide hollow shaft 101, and then passes through the discharge hole 306 and enters the external pipe 307. Finally, it is discharged from the discharge connector 308. When the remaining material is discharged, since the wall-mounted guide membrane 402 is attached to the bottom of the mixing tank 301, the remaining material can be completely sucked out relatively cleanly. During cleaning, the external water pipe can be opened. After the external water pipe is opened, water is guided into the flow loop 211 through the inlet pipe 215. The water flow enters the flow loop 211 and is distributed into each branch channel 212. Then the water flow is sprayed out from the nozzle 214, thereby focusing on rinsing the inside of the circulation tank 202. Then the mixing motor 310 is started, and clean water is introduced through the tank cover 302. Through the vibration generated by the eccentric wheel 103 and the pumping of the circulating centrifugal fan blade 102, the water flow continuously circulates and rinses inside the mixing tank 301.
