Description

Technical Field

[0001] This utility model relates to the field of precious metal refining technology, specifically to a precious metal impurity removal device. Background Technology

[0002] Precious metal refining is a technical process that extracts high-purity precious metals from ores, waste, or alloys using physical, chemical, or biological methods. Its core purpose is to remove impurities and improve the ductility, stability, and economic value of the metals. Before physical calcination and chemical purification, it is necessary to remove non-metallic and metallic impurity particles from the precious metal raw materials, which is beneficial for subsequent refining.

[0003] When removing non-metallic impurity particles, centrifugation can be used to separate and remove them based on differences in physical density. However, for metallic impurity particles, since the physical density of metallic impurities is not much different from that of precious metals, it is difficult to separate and remove them using traditional centrifugation methods. Therefore, after centrifugation, other methods are needed to remove metallic impurity particles from precious metals, making the precious metal impurity removal process cumbersome and reducing the efficiency of precious metal impurity removal. Utility Model Content

[0004] The purpose of this invention is to address the problem that traditional centrifugation methods can only remove non-metallic impurity particles from precious metals, but have difficulty removing metallic impurity particles, requiring secondary impurity removal and reducing the efficiency of precious metal impurity removal. This invention provides a precious metal impurity removal device.

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0006] A precious metal impurity removal device includes a tank, a support frame fixedly installed at the bottom of the tank, a feeding cylinder fixedly connected to the top of the support frame, a rotating shaft rotatably connected to the center of the inside of the feeding cylinder, a pushing fan blade fixedly installed on the periphery of the center of the rotating shaft, a swirling fan blade rotatably connected to the center of the bottom of the tank, and the center of the top of the swirling fan blade is fixedly installed to the rotating shaft, a motor is fixedly installed at the center of the top of the feeding cylinder, and the motor is drivenly connected to the rotating shaft, a feeding pipe is fixedly connected to one side of the feeding cylinder, and a sorting component is provided at the bottom of the tank.

[0007] Furthermore, the pushing fan blade is located inside the feeding cylinder, and the connection between the feeding pipe and the feeding cylinder is located above the pushing fan blade, so that after feeding, the feeding pipe can be pushed downward by the rotation of the pushing fan blade.

[0008] Furthermore, the sorting component includes an annular groove, an annular groove is provided at the bottom of the tank body, an annular plate is provided at the top of the annular groove, a spring is fixedly connected between the bottom end of the annular plate and the bottom end of the annular groove, and discharge holes are symmetrically provided on both sides of the bottom of the annular groove, the discharge holes penetrating downward through the tank body.

[0009] Furthermore, there are three sets of annular grooves and annular plates, all located on the outer side of the swirl fan blades. A magnetic ring is fixedly installed inside the annular plate located in the middle position, which can attract particles that have moved to the annular plate in the middle position.

[0010] Furthermore, the top of each annular plate is provided with protrusions to increase friction, making it easier for particles to remain on the annular plate.

[0011] Furthermore, the inner side of the top of the annular groove all tapers towards the middle, and the inner and outer sides of the top of the annular plate are provided with bevels. There are gaps between the inner and outer walls of the annular plate and the inner wall of the annular groove, so that in a static state, the annular plate can block the annular groove upward under the action of the spring, and when the annular plate moves downward, the particles remaining above the annular plate can flow into the interior of the annular groove along with the liquid from the gap between the annular plate and the annular groove.

[0012] Furthermore, three sets of discharge pipes are fixedly installed at the bottom of the tank, and the three sets of discharge pipes are respectively connected to the discharge holes at the bottom of the three sets of annular grooves. The discharge pipes are connected to the suction pump through pipes, so that the interior of the three sets of annular grooves can be suctioned respectively.

[0013] The beneficial effects of this utility model are as follows:

[0014] This invention, through the design of the sorting component at the bottom of the tank, utilizes centrifugal force to sort non-metallic impurity particles in precious metal raw materials during the rotation of the driving fan blades and swirl fan blades. Then, through the action of the magnetic ring inside the middle annular plate, metallic impurity particles can also be sorted by magnetic attraction during the centrifugal sorting process. Finally, the sorted particles are extracted and collected by the discharge pipe and the sinking of the annular plate. Therefore, it can remove both non-metallic and metallic impurity particles from precious metal raw materials in one go, improving the impurity removal efficiency of precious metals.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0025] A preferred embodiment of the present invention, a precious metal impurity removal device, will be described in detail below, such as... Figures 1-8 As shown, a precious metal impurity removal device includes a tank 1, a support frame 2 fixedly installed at the bottom of the tank 1, a feeding cylinder 3 fixedly connected to the top of the support frame 2, a rotating shaft 4 rotatably connected to the center of the inside of the feeding cylinder 3, a pushing fan blade 5 fixedly installed on the outer periphery of the middle part of the rotating shaft 4, a swirling fan blade 6 rotatably connected to the center of the bottom inside the tank 1, and the center of the top of the swirling fan blade 6 is fixedly installed to the rotating shaft 4, a motor 7 is fixedly installed at the center of the top of the feeding cylinder 3, and the motor 7 is drivenly connected to the rotating shaft 4, a feeding pipe 8 is fixedly connected to one side of the feeding cylinder 3, the pushing fan blade 5 is located inside the feeding cylinder 3, and the connection between the feeding pipe 8 and the feeding cylinder 3 is located above the pushing fan blade 5, so that after the feeding pipe 8 is filled, it can be pushed downward by the rotation of the pushing fan blade 5.

[0026] A sorting assembly 9 is provided at the bottom of the tank body 1. The sorting assembly 9 includes an annular groove 91. An annular groove 91 is opened at the bottom inside the tank body 1. An annular plate 92 is provided above the annular groove 91. The top of the annular plate 92 is provided with a protrusion to increase the friction force, so that the particles can stay on the annular plate 92. There are three sets of annular grooves 91 and annular plates 92, all of which are located on the outside of the swirl fan blade 6. A magnetic ring 95 is fixedly installed inside the annular plate 92 located in the middle position, so as to attract the particles that move to the annular plate 92 in the middle position.

[0027] A spring 93 is fixedly connected between the bottom end of the annular plate 92 and the bottom end of the annular groove 91. Discharge holes 94 are symmetrically opened on both sides of the bottom of the annular groove 91, and the discharge holes 94 penetrate downward through the tank body 1.

[0028] Furthermore, the inner side of the top of the annular groove 91 all tapers towards the middle, and the inner and outer sides of the top of the annular plate 92 are provided with bevels. There are gaps between the inner and outer walls of the annular plate 92 and the inner wall of the annular groove 91, so that in a static state, the annular plate 92 can block the annular groove 91 upward under the action of the spring 93. When the annular plate 92 moves downward, the particles remaining above the annular plate 92 can flow into the interior of the annular groove 91 along with the liquid from the gap between the annular plate 92 and the annular groove 91.

[0029] Three sets of discharge pipes 10 are fixedly installed at the bottom of the tank body 1, and the three sets of discharge pipes 10 are respectively connected to the discharge holes 94 at the bottom of the three sets of annular grooves 91. The discharge pipes 10 are connected to the suction pump through the pipes, so that the interior of the three sets of annular grooves 91 can be suctioned respectively.

[0030] The working principle of this utility model is as follows:

[0031] During the impurity removal process, the liquid containing precious metal raw materials is added into the inside of the feeding cylinder 3 through the feeding pipe 8, and then enters the inside of the tank 1 through the feeding cylinder 3, until the liquid level of the precious metal raw materials is above the driving fan blade 5.

[0032] Then, start the motor 7 to drive the rotating shaft 4 to rotate. During the rotation of the rotating shaft 4, the bottom swirl fan blade 6 can be driven to rotate at the bottom of the tank 1, thereby driving the precious metal raw material liquid inside the tank 1 to rotate and flow. At the same time, the rotating shaft 4 will also drive the push fan blade 5 to rotate, so that the push fan blade 5 can give the particles in the precious metal raw material liquid a downward thrust, so that the particles can be better deposited at the bottom of the tank 1.

[0033] During the rotation and flow of the precious metal raw material liquid inside the tank 1, the particles deposited at the bottom of the tank 1 can move outward under the action of centrifugal force. According to the difference in physical density, non-metallic impurity particles will stay at the inner ring plate 92 on the outer ring of the swirl fan blade 6 at the bottom of the tank 1, while the metal particles will move outward. Through the action of the magnetic ring 95 inside the middle ring plate 92, the outward moving metal impurity particles will be attracted, causing the metal impurity particles to stay at the middle ring plate 92, while the precious metal particles are not affected by the magnetic force and will continue to move outward to the outer ring plate 92, thereby achieving the separation of non-metallic impurity particles, metal impurity particles and precious metal particles.

[0034] After the sorting is completed, the motor 7 is turned off, and the discharge pipe 10 and the suction pump work together to extract the contents of each annular groove 91. Under the action of negative pressure, the annular plate 92 can be compressed by the spring 93 and moved downward, so that the particles remaining on each annular plate 92 can enter the contents of the annular groove 91 along with the liquid, and finally be extracted and collected by the discharge pipe 10.

[0035] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
