Description

Technical Field

[0001] This utility model relates to the field of chemical production technology, specifically to a high-efficiency stirring device for a leaching tank. Background Technology

[0002] Leaching refers to the process of extracting soluble substances from solids using chemical solvents, also known as leaching. Metal leaching is the process of extracting metals from solids using chemical solvents. Generally, this process requires stirring to ensure a higher metal leaching rate, thus requiring the use of a leaching stirring device.

[0003] Chinese patent CN119771210A discloses a high-efficiency leaching stirring device, including a base plate, a stirring cylinder fixedly installed on the top of the base plate, a cooling chamber inside the stirring cylinder, an electric heating ring embedded inside the stirring cylinder, a temperature sensor and a pressure sensor fixedly installed on the top of the stirring cylinder, a feed inlet and a liquid inlet on the top of the stirring cylinder, two first electromagnetic valves installed on the feed inlet and the liquid inlet, a cooling mechanism and a circulation mechanism on the top of the base plate, and a drive mechanism on the bottom of the stirring cylinder. This high-efficiency leaching stirring device, through the synergistic effect of the cooling mechanism, the electric heating ring, the temperature sensor and the controller, facilitates the control of the temperature inside the stirring cylinder, thereby achieving temperature control during the material processing process. It solves the problem that existing leaching stirring devices are difficult to control the reaction environment, which further limits their application range and the improvement of leaching efficiency.

[0004] However, the following shortcomings still exist:

[0005] In current mixing devices, the material tends to swirl during operation as the mixing components rotate, preventing thorough and uniform mixing. Furthermore, the mixing components come into contact with the material at the bottom of the device, making it difficult to mix evenly. Additionally, after mixing, material tends to adhere to the surface of the mixing components, and this adhered material mixes with the new material during the next mixing cycle, severely impacting the mixing effect. Therefore, those skilled in the art provide a high-efficiency mixing device for leaching tanks to solve the problems mentioned in the background art. Utility Model Content

[0006] The purpose of this invention is to provide a high-efficiency stirring device for a leaching tank, which solves the problems mentioned in the background section of the prior art.

[0007] This utility model provides the following technical solution: a high-efficiency stirring device for a leaching tank, comprising a liquid storage component for storing materials, the liquid storage component including a stirring cylinder, the interior of the liquid storage component being equipped with a stirring component for mixing materials, the stirring component being provided with a stirring shaft, the stirring shaft being located at the center of the inner wall of the stirring cylinder, the inner wall of the stirring cylinder being provided with fan-shaped stirring blades near the stirring shaft, the bottom surface of the stirring cylinder being provided with a stirring ring and stirring blades near the lower end of the stirring shaft, and the upper end of the stirring component being provided with a cleaning component for cleaning the stirring component.

[0008] As a preferred embodiment of the above technical solution, the upper side of the mixing drum is provided with a feed inlet, and the lower center of the mixing drum is provided with a discharge outlet.

[0009] As a preferred embodiment of the above technical solution, a guide tube is fixedly installed on the inner wall of the stirring cylinder, and baffles are evenly distributed in a ring array on the inner diameter of the guide tube, and a plurality of baffles are provided.

[0010] As a preferred embodiment of the above technical solution, the stirring assembly includes a motor, which is located at the upper center of the stirring drum. The output end of the motor is rotatably connected to a stirring shaft, and the outer diameter of the stirring shaft is evenly distributed with a number of stirring blades in a ring shape.

[0011] As a preferred embodiment of the above technical solution, a bottom stirring ring is fixedly connected to the lower end of the stirring shaft, and the bottom stirring ring has bottom stirring blades evenly distributed in a ring array on its outer diameter.

[0012] As a preferred embodiment of the above technical solution, the cleaning assembly includes a water storage tank, which is fixedly installed on one side of the mixing drum. A water pump is provided at the center of the upper end of the water storage tank, and a water supply pipe is fixedly connected to the water supply end of the water pump. The water supply pipe is connected to a diversion pipe located at the upper end of the guide tube through the mixing drum. There are two diversion pipes, and several nozzles are provided at the lower ends of the two diversion pipes. The several nozzles are located at the upper end of the inner wall of the guide tube.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention uses a motor to start the stirring shaft, which drives the stirring blades and the bottom stirring ring to rotate synchronously. The stirring blades rotate at high speed inside the guide tube, generating axial thrust to push the material upwards along the tube. After initial dispersion, the material overflows and diffuses from the tube opening. The bottom stirring ring drives the blades to agitate the material at the bottom, pushing the deposited particles upwards, eliminating dead zones and replenishing the material below the guide tube. The material outside the guide tube is blocked by gravity and the baffle, and after being circumferentially swirled, it flows towards the tube wall and then folds back downwards, returning to the bottom of the guide tube, forming a closed-loop flow of rising inside the tube and falling outside. The blade shearing, circulation convection, and baffle turbulence work together to promote the collision and refinement of material particles and the rapid diffusion of components. After the material is stirred and discharged, a water tank provides clean water, which is pressurized by a water pump and delivered to the inside of the stirring tube through a water pipe. The water flows through the through hole into the distribution pipe at the top of the guide tube and is evenly distributed to multiple nozzles. The high-pressure water flow from the nozzles directly washes the inner wall of the guide tube and the surface of the stirring blades, effectively removing residual material residues, avoiding pollution or blockage, and achieving efficient cleaning of the core area.

Detailed Implementation

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] Please see Figures 1-5As shown, this utility model provides a technical solution: a high-efficiency stirring device for a leaching tank, including a liquid storage component 1 for storing materials, the liquid storage component 1 including a stirring cylinder 101, the inside of the liquid storage component 1 is equipped with a stirring component 2 for mixing materials, the stirring component 2 is provided with a stirring shaft 202, the stirring shaft 202 is located at the center of the inner wall of the stirring cylinder 101, the inner wall of the stirring cylinder 101 near the stirring shaft 202 is provided with a fan-shaped stirring blade 203, the bottom surface of the stirring cylinder 101 near the lower end of the stirring shaft 202 is provided with a stirring ring 204 and a stirring blade 205, and the upper end of the stirring component 2 is provided with a cleaning component 3 for cleaning the stirring component 2.

[0024] As one implementation method in this embodiment, please refer to Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, a feed inlet 102 is provided on one side of the upper end of the mixing drum 101, and a discharge outlet 103 is provided at the center of the lower end of the mixing drum 101. A guide tube 104 is fixedly installed on the inner wall of the mixing drum 101. Baffles 105 are evenly distributed in a ring array on the inner diameter of the guide tube 104. Several baffles 105 are provided. The mixing assembly 2 includes a motor 201. The motor 201 is located at the center of the upper end of the mixing drum 101. The output end of the motor 201 is rotatably connected to a mixing shaft 202. Several mixing blades 203 are evenly distributed in a ring on the outer diameter of the mixing shaft 202. A bottom mixing ring 204 is fixedly connected to the lower end of the mixing shaft 202. Bottom mixing blades 205 are evenly distributed in a ring array on the outer diameter of the bottom mixing ring 204.

[0025] Furthermore, after the material to be stirred enters the mixing drum 101 through the feed inlet 102, it often exhibits stratification, sedimentation, or localized unevenness in its initial state due to density differences or insufficient flowability. At this time, the motor 201 starts, and the rotational torque is precisely transmitted to the mixing blades 203 and the bottom mixing ring 204 through the mixing shaft 202, initiating a high-efficiency mixing cycle. The mixing blades 203 rotate at high speed inside the guide tube 104, generating a strong axial thrust to push the material inside the tube upward along the inside of the guide tube 104. On the other hand, the blade shearing action creates radial turbulence, allowing the material to be initially dispersed inside the guide tube 104 before overflowing from the tube opening and spreading outwards. At the same time, the bottom mixing ring 204 drives the bottom mixing blades 205 to rotate synchronously, specifically stirring the bottom area of ​​the mixing drum 101, pushing the deposited particles or sludge upwards. This effectively eliminates the bottom mixing dead zone and replenishes the material below the guide tube 104, forming an auxiliary circulation from bottom to top, preventing the material from accumulating at the bottom and causing the material to be subjected to weight. The flow field is transformed by the combined action of force and the inner wall baffle 105. The baffle 105 blocks the circumferential swirling motion of the material generated by the impeller, converting the rotational kinetic energy into radial impact and turbulent disturbance. This forces the material to flow towards the cylinder wall and then fold back down along the cylinder wall, eventually flowing back into the bottom of the guide cylinder 104, forming a closed axial circulation flow that rises inside the guide cylinder 104 and falls outside the cylinder. This achieves overall circulation and mixing of the material throughout the cylinder. During this process, the shearing and dispersion of the stirring impeller 203 and the convection of the circulation flow work together, combined with the local turbulence induced by the baffle 105, to promote the full collision and refinement of material particles and the rapid diffusion of components, accelerating the mixing or reaction process. When the material reaches a uniformly mixed state, it is discharged through the discharge port 103 at the lower center to the subsequent process. With the continuous pushing action of the bottom stirring blades 205, the residual amount of material is greatly reduced when discharged, and the uniformly mixed material can stably ensure the quality of subsequent processes. Ultimately, this achieves the efficient mixing, stirring and conveying of materials from input to output.

[0026] As one implementation method in this embodiment, please refer to Figures 2-3 As shown, the cleaning component 3 includes a water storage tank 301, which is fixedly installed on one side of the mixing drum 101. A water pump 302 is provided at the center of the upper end of the water storage tank 301. A water supply pipe 303 is fixedly connected to the water supply end of the water pump 302. The water supply pipe 303 is connected to a diversion pipe 304 provided at the upper end of the guide tube 104 through the mixing drum 101. There are two diversion pipes 304. Several nozzles 305 are provided at the lower end of the two diversion pipes 304. The several nozzles 305 are located at the upper end of the inner wall of the guide tube 104.

[0027] Furthermore, after the mixing device completes the mixing and discharge of a batch of materials, residual material remains in the mixing drum 101 and the guide tube 104. The cleaning assembly 3 needs to be activated for cleaning. At this time, the water storage tank 301 has stored sufficient clean water to provide a water source for cleaning. After the water pump 302 starts, it pressurizes the clean water in the water storage tank 301 and delivers the high-pressure water flow to the inside of the mixing drum 101 through the water pipe 303. The water flow passes through the through hole of the mixing drum 101 and enters the diversion pipe 304 located at the upper end of the guide tube 104. The diversion pipe 304 divides the single water flow into two paths, evenly distributing the water flow to multiple nozzles 305. Since the nozzles 305 are located at the upper end of the inner wall of the guide tube 104 and face inwards, the sprayed high-pressure water flow can directly wash the inner wall of the guide tube 104 and the mixing blades 203. The upper surface and surrounding area of ​​the mixing component are key areas where material residue is easily left during mixing. The high-pressure water spray removes residual material residue from the inner wall of the guide cylinder 104 and the surface of the blades through impact and dissolution. Through directional water supply and spray rinsing, the core area of ​​the mixing component 2 is efficiently cleaned, avoiding material residue contamination or equipment blockage.

[0028] Working principle: After the material to be stirred enters the mixing drum 101 through the feed inlet 102, it is prone to stratification and sedimentation due to density or flowability issues. After the motor 201 starts, it drives the stirring blades 203 and the bottom stirring ring 204 to operate synchronously through the stirring shaft 202. The stirring blades 203 rotate at high speed inside the guide tube 104, pushing the material upward and overflowing from the drum opening. The bottom blades agitate the bottom material, pushing the sedimented particles upward and eliminating dead zones. The material outside the guide tube 104 is blocked by gravity and the baffle 105, flowing towards the drum wall and then returning to the bottom of the guide tube 104, forming an upward circulation inside the drum and a downward circulation outside the drum. The stirring blades 203 shear and circulate convection. The combined action of the baffle 105 and the turbulent flow accelerates the mixing reaction of the materials. The mixed materials are discharged through the outlet 103. The bottom blades reduce residue, achieving efficient mixing, stirring and conveying of materials. After the materials are stirred and discharged, the water tank 301 provides clean water. The water pump 302 pressurizes the water and delivers it to the inside of the mixing drum 101 through the water pipe 303. The water flows through the through hole into the diversion pipe 304 at the top of the guide tube 104 and is evenly distributed to multiple nozzles 305. The high-pressure water flow from the nozzles 305 directly washes the inner wall of the guide tube 104 and the surface of the stirring blades 203, effectively removing residual material residue, avoiding pollution or blockage, and achieving efficient cleaning of the core area.

[0029] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
