Description

Technical Field

[0001] This utility model belongs to the technical field of microbial screening and enrichment devices, and in particular relates to a microbial screening and enrichment device for bio-oxidation gold extraction. Background Technology

[0002] Biological oxidation has advantages such as low cost, environmental friendliness, and strong adaptability to low-grade and difficult-to-process ores, and has gradually become an important research direction in the field of gold extraction. It mainly relies on specific microorganisms to recover valuable metals in the ore in the form of ions or precipitates under suitable environmental conditions, thereby improving the gold recovery rate and resource utilization. In the process of gold extraction, it is necessary to fully stir the microorganisms, ore and solution to ensure thorough mixing and improve the gold extraction efficiency. However, the stirring effect of most current equipment is not ideal. Therefore, a microbial screening and enrichment device for biological oxidation gold extraction is proposed. Utility Model Content

[0003] The purpose of this invention is to provide a microbial screening and enrichment device for bio-oxidation gold extraction. By setting up a stirring assembly, specifically, a motor is started and rotated via a rotating shaft gear one. Simultaneously, the rotation of gear one drives several rotating rods via several gear twos. At this time, several stirring blades inside the stirring leaching chamber, through the rotation of the rotating rods, thoroughly stir the microorganisms, ore, and solution inside the stirring leaching chamber, ensuring that the microorganisms are evenly distributed in the solution. This even distribution allows them to fully contact the gold-bearing ore or material, solving the problem that existing gold extraction processes require thorough stirring of microorganisms, ore, and solution to ensure proper mixing and improve extraction efficiency; however, the stirring effect of most current equipment is not ideal.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0005] This utility model relates to a microbial screening and enrichment device for bio-oxidation gold extraction, comprising a main frame mechanism. The main frame mechanism includes a stirring leaching chamber. A drain port is fixedly connected to the left side of the stirring leaching chamber. A fixing ring is fixedly connected to the top of the outer surface of the stirring leaching chamber. A cover is provided on the top of the stirring leaching chamber, with the bottom of the cover contacting the top of the fixing ring. A stirring assembly is provided inside the stirring leaching chamber, and a filter assembly is provided at the bottom of the stirring assembly. The stirring assembly includes a motor, with the top of the motor fixedly connected to the bottom of the stirring leaching chamber. A cavity is formed at the bottom inside the stirring leaching chamber. A rotating shaft is rotatably connected to the bottom inside the stirring leaching chamber, passing through the cavity and extending into the stirring leaching chamber. A gear is provided inside the cavity, with the inside of the gear fixedly connected to the outer surface of the rotating shaft. The gear is fixedly connected to a plurality of gears two meshing on its outer surface. The stirring leaching chamber contains a plurality of stirring blades. The top output end of the motor is fixedly connected to the bottom of the rotating shaft via a coupling. Rotating rods are fixedly connected inside each of the gears two. These rotating rods penetrate the cavity and extend into the stirring leaching chamber. The outer surfaces of these rotating rods are fixedly connected to the corresponding sides of the stirring blades. When the motor is started, it rotates via the rotating shaft and gear one. Simultaneously, the rotation of gear one drives the rotation of the rotating rods via the gears two. At this time, the stirring blades inside the stirring leaching chamber, through the rotation of the rotating rods, thoroughly stir the microorganisms, ore, and solution inside the chamber, ensuring that the microorganisms are evenly distributed in the solution. This even distribution allows them to fully contact the gold-bearing ore or material.

[0006] Furthermore, a guide plate is provided at the bottom of several of the stirring blades. An electric valve is fixedly connected to the inner ring of the guide plate, and the outer ring of the guide plate is fixedly connected to the inner wall of the stirring leaching chamber. The inside of the guide plate is rotatably connected to the outer surface of several rotating rods. When the stirring blades rotate, they will fully stir the microorganisms, ore and solution inside the stirring leaching chamber, so that the microorganisms and ore can fully contact each other. The metabolism of the microorganisms will be used to oxidize and decompose the gold in the ore to achieve the extraction of gold. After the separation and gold extraction are completed, the staff will open the electric valve to allow the gold-containing solution to flow downward through the guide plate.

[0007] Furthermore, the filtration assembly includes a guide plate, the outer ring of which is fixedly connected to the inner wall of the stirred leaching chamber, the inner ring of which is rotatably connected to the outer surface of the rotating shaft, a filter plate on the top of the guide plate, the outer ring of which is fixedly connected to the inner wall of the stirred leaching chamber, the filter plate and the inner ring of which are rotatably connected to the outer surfaces of several rotating rods, the rotating shaft passing through the filter plate and extending to the top, the top of which contacts a second limiting plate, the inner ring of which is fixedly connected to the outer surface of the rotating shaft. The filter plate prevents impurities in the solution from mixing with gold, and the filtered solution is then guided by the guide plate and discharged from the drain port.

[0008] Furthermore, a spring is fitted on the top of the outer surface of the rotating shaft. The bottom of the spring is fixedly connected to the top of the second limiting plate. The side of the spring away from the second limiting plate is fixedly connected to the first limiting plate. The inner ring of the first limiting plate is fixedly connected to the outer surface of the rotating shaft. When the second limiting plate moves upward, it will compress the spring. The spring will then contract and store force due to the limiting action of the first limiting plate. At the same time, the spring will generate a certain rebound force and drive the second limiting plate to reset. When the second limiting plate resets, it will drive the filter plate to reset. This repetition will cause the filter plate to vibrate, thus preventing the filter plate from clogging while filtering.

[0009] Furthermore, a number of impact blocks are fixedly connected to the bottom of the filter plate, and a limit plate three is provided on the top of the guide plate. The inner ring of the limit plate three is fixedly connected to the outer surface of the rotating shaft, and a number of impact rods are fixedly connected to the top of the limit plate three. The tops of the impact rods are in contact with the bottoms of the impact blocks. When the rotating shaft rotates, it will drive the limit plate three to rotate. When the limit plate three rotates, it will drive the impact rods to move. At this time, the tops of the impact rods will contact the bottoms of the impact blocks, and the impact blocks will be subjected to force, which will drive the filter plate to move upward. When the filter plate moves upward, it will drive the limit plate two to move together.

[0010] The rotating shaft is driven by a motor. The filter plate and the guide plate are both provided with round holes and are sleeved on the rotating rod. The top of the filter plate contacts the second limiting plate, and the inner ring of the second limiting plate is fixedly connected to the rotating shaft.

[0011] This utility model has the following beneficial effects:

[0012] 1. This utility model, by setting up a stirring assembly, specifically, starts a motor to rotate a shaft gear one. While gear one rotates, it drives several rotating rods through several gear twos. At this time, several stirring blades inside the stirring leaching chamber will fully stir the microorganisms, ore and solution inside the stirring leaching chamber through the rotation of the rotating rods, so that the microorganisms are evenly distributed in the solution. Even distribution allows them to fully contact the gold-bearing ore or materials, avoiding local microbial concentrations that are too high or too low, thereby ensuring that the oxidation reaction proceeds efficiently in all parts.

[0013] 2. This utility model, through the setting of a filter assembly, specifically, when the rotating shaft rotates, it drives several impact rods to move through the limiting plate three. At this time, the tops of the several impact rods will contact the bottom of the impact blocks, and the impact blocks will be subjected to force, which will drive the filter plate to move and squeeze the spring. The spring will generate a certain rebound force and drive the limiting plate two to reset, so that the filter plate achieves the effect of vibration. While filtering, the filter plate is prevented from clogging. Filtration can separate these impurities from the solution, improve the purity of gold and the extraction efficiency.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 As shown, this utility model is a microbial screening and enrichment device for bio-oxidation gold extraction, including a main frame mechanism 1. The main frame mechanism 1 includes a stirring leaching chamber 111. A drain port 112 is fixedly connected to the left side of the stirring leaching chamber 111. A fixing ring 113 is fixedly connected to the top of the outer surface of the stirring leaching chamber 111. A cover 114 is provided on the top of the stirring leaching chamber 111, and the bottom of the cover 114 contacts the top of the fixing ring 113. A stirring assembly 2 is provided inside the stirring leaching chamber 111. The bottom of the stirring assembly 2 is provided with... The filter assembly 3 and the stirring assembly 2 include a motor 211. The top of the motor 211 is fixedly connected to the bottom of the stirring leaching chamber 111. A cavity is opened at the bottom inside the stirring leaching chamber 111. A rotating shaft 218 is rotatably connected to the bottom inside the stirring leaching chamber 111. The rotating shaft 218 passes through the cavity and extends into the stirring leaching chamber 111. A gear 216 is installed inside the cavity. The inside of the gear 216 is fixedly connected to the outer surface of the rotating shaft 218. Several teeth are meshed on the outer surface of the gear 216. The stirring leaching chamber 111 is equipped with several stirring blades 212. The top output end of the motor 211 is fixedly connected to the bottom of the rotating shaft 218 via a coupling. Several gears 217 are fixedly connected to rotating rods 213. The rotating rods 213 penetrate the cavity and extend into the stirring leaching chamber 111. The outer surfaces of the rotating rods 213 are fixedly connected to the corresponding side of the stirring blades 212. When the motor 211 is started, it rotates through the first gear 216 of the rotating shaft 218. While the first gear 216 rotates, it drives the rotating rods 213 to rotate through the gears 217. At this time, the stirring blades 212 inside the stirring leaching chamber 111 will fully stir the microorganisms, ore and solution inside the stirring leaching chamber 111 through the rotation of the rotating rods 213. This ensures that the microorganisms are evenly distributed in the solution. Even distribution allows them to fully contact the gold-bearing ore or material, avoiding excessively high or low local microbial concentrations, thereby ensuring that the oxidation reaction proceeds efficiently in all parts.

[0026] A guide plate 214 is provided at the bottom of several stirring blades 212. An electric valve 215 is fixedly connected to the inner ring of the guide plate 214. The outer ring of the guide plate 214 is fixedly connected to the inner wall of the stirring leaching chamber 111. The inside of the guide plate 214 is rotatably connected to the outer surface of several rotating rods 213.

[0027] The filter assembly 3 includes a guide plate 312. The outer ring of the guide plate 312 is fixedly connected to the inner wall of the stirred leaching chamber 111. The interior of the guide plate 312 is rotatably connected to the outer surface of the rotating shaft 218. A filter plate 311 is provided on the top of the guide plate 312. The outer ring of the filter plate 311 is fixedly connected to the inner wall of the stirred leaching chamber 111. The interior of the filter plate 311 and the guide plate 312 is rotatably connected to the outer surfaces of several rotating rods 213. The rotating shaft 218 passes through the filter plate 311 and extends to the top. The top of the filter plate 311 contacts a second limiting plate 315. The inner ring of the second limiting plate 315 is fixedly connected to the outer surface of the rotating shaft 218. When the rotating shaft 218 rotates... When shaft 218 rotates, it drives several impact rods 317 to move through limit plate 318. At this time, the tops of the impact rods 317 will contact the bottom of the impact block 316. The impact block 316 will be subjected to force, which will drive the filter plate 311 to move and compress the spring 314. The spring 314 will generate a certain rebound force and drive limit plate 315 to reset, so that the filter plate 311 will vibrate. While filtering, the filter plate 311 will not be blocked. Filtration can separate these impurities from the solution, improve the purity of gold and the extraction efficiency.

[0028] A spring 314 is fitted on the top of the outer surface of the rotating shaft 218. The bottom of the spring 314 is fixedly connected to the top of the second limiting plate 315. The side of the spring 314 away from the second limiting plate 315 is fixedly connected to the first limiting plate 313. The inner ring of the first limiting plate 313 is fixedly connected to the outer surface of the rotating shaft 218.

[0029] Several impact blocks 316 are fixedly connected to the bottom of the filter plate 311. A limit plate 318 is provided on the top of the guide plate 312. The inner ring of the limit plate 318 is fixedly connected to the outer surface of the rotating shaft 218. Several impact rods 317 are fixedly connected to the top of the limit plate 318. The top of the several impact rods 317 are in contact with the bottom of the several impact blocks 316.

[0030] A specific application of this embodiment is as follows: In use, the operator first separates the cover 114 from the fixing ring 113, then adds the mixture containing microorganisms, ore, and solution into the stirred leaching chamber 111. At this time, the electric valve 215 is in the closed state. Then, the operator places the cover 114 on top of the stirred leaching chamber 111 and secures it to the fixing ring 113. Afterward, the motor 211 is started to drive the rotating shaft 218 to rotate. When the rotating shaft 218 rotates, it drives the gear 216 to rotate. Simultaneously, the gear 216 rotates... The rotation of several gears 217 causes several rotating rods 213 to rotate. Simultaneously, several stirring blades 212 inside the stirring leaching chamber 111 rotate along with the rotating rods 213. This rotation of the stirring blades 212 thoroughly stirs the microorganisms, ore, and solution inside the stirring leaching chamber 111, ensuring full contact between the microorganisms and the ore. The metabolic activity of the microorganisms oxidizes and decomposes the gold in the ore, achieving gold extraction. After the gold extraction is complete, the staff... Opening the electric valve 215 allows the gold-containing solution to flow downwards through the guide plate 214. Simultaneously, when the rotating shaft 218 rotates, it drives the limiting plate 318 to rotate. The rotation of the limiting plate 318 causes several impact rods 317 to move. At this time, the tops of the impact rods 317 contact the bottoms of the impact blocks 316, causing the impact blocks 316 to be subjected to force, which in turn drives the filter plate 311 to move upwards. When the filter plate 311 moves upwards, it drives the limiting plate 315 to move as well. When the limiting plate 315 moves upwards, it... When spring 314 is compressed, it will contract and store force due to the limiting plate 313. At the same time, spring 314 will generate a certain rebound force and drive the limiting plate 315 to reset. When the limiting plate 315 resets, it will drive the filter plate 311 to reset. This reciprocating motion will cause the filter plate 311 to vibrate, which will prevent the filter plate 311 from becoming clogged while filtering. At the same time, the filter plate 311 will prevent impurities in the solution from mixing with the gold. The filtered solution will then be guided by the guide plate 312 and discharged from the drain port 112.
