Description

Technical Field

[0001] This utility model relates to the technical field of precious metal reaction devices, specifically a reaction device for the hydrometallurgical refining of precious metals. Background Technology

[0002] Precious metals generally refer to metals that are scarce in the Earth's crust and have high mining and refining costs. They are considered "precious" due to their rarity, corrosion resistance, good electrical and thermal conductivity, and applications in industry and jewelry manufacturing. Precious metals are increasingly widely used in traditional industries and modern high-tech industries. In modern electronics industries such as electronics, communication, aerospace, chemical, medical, automotive exhaust purification, and fiberglass, more and more electronic components can use precious metals as raw materials. Precious metal hydrorefining is a technique that uses chemical solvents (such as acids, alkalis, or compounding agents) to dissolve, separate, and purify precious metals (such as gold, silver, platinum, palladium, etc.).

[0003] Traditional reaction devices have a relatively simple reaction method, making it difficult to achieve uniform mixing of the reaction solution and precious metals, which affects the reaction efficiency and metal recovery rate. After the reaction, additional filtration equipment is required to separate the residue from the solution, increasing the process and cost. Therefore, we propose a reaction device for wet refining of precious metals. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a reaction device for wet refining of precious metals. By utilizing the ultrasonic cavitation effect to enhance the mass transfer process, combined with precise temperature control and corrosion-resistant design, it not only accelerates the dissolution reaction of precious metals, but also realizes the integrated operation of reaction and separation, effectively reducing the loss of precious metals and the amount of chemical reagents used. The reaction device has comprehensive advantages such as high efficiency, energy saving and environmental protection, and is suitable for high-purity refining of precious metals such as gold, silver and platinum. It can effectively solve the problems in the background technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a reaction apparatus for hydrometallurgical refining of precious metals, comprising a tank and an ultrasonic generator;

[0006] Tank body: An inlet shell is connected to the top of the outer side. The top surface of the tank body is fitted with the bottom surface of the tank cover. A base frame is fixed to the bottom surface of the tank body. A first motor is installed on both sides of the bottom surface of the base frame. The output shaft of the first motor is connected to the bottom end of the mixing frame. The mixing frame is located on the bottom surface inside the tank body. An adjustment unit is provided on the bottom surface of the tank cover. A transducer is installed inside the adjustment unit. An ultrasonic generator is installed in the middle of the top surface of the tank cover. A filtration unit is provided inside the tank body.

[0007] The system also includes a controller, which is fixed to the surface of the tank. The input end of the transducer is electrically connected to the output end of the ultrasonic generator. The input ends of the first motor and the ultrasonic generator are electrically connected to the output end of the controller. The input end of the controller is electrically connected to the output end of an external power supply.

[0008] The ultrasonic generator, in conjunction with the transducer, produces high-frequency vibrations, creating a cavitation effect in the liquid. This significantly improves the mass transfer efficiency between the precious metal and the solvent. Simultaneously, the first motor drives the mixing rack to stir, accelerating dissolution and chemical reactions. The generated ultrasonic waves can break up particle agglomerates, reducing precious metal residue and improving the recovery rate.

[0009] Furthermore, the adjustment unit includes a rotating wheel, a screw, a fixed column, an adjustment frame, a mounting base, and bolts. There are two fixed columns, each fixed to one side of the bottom surface of the can lid. There are two rotating wheels, each installed on one side of the top surface of the can lid. The bottom end of the rotating wheel is connected to the top end of the screw. The screw is located inside the fixed column. The adjustment frame is slidably installed inside the fixed column. The screw hole on the surface of the adjustment frame is threadedly connected to the screw. The mounting base is fixed inside the adjustment frame. The mounting base is inserted into the transducer. The screw hole on the surface of the mounting base is threadedly connected to the bolts. Rotating the rotating wheel drives the screw to rotate, thereby adjusting the height of the transducer inside the mounting base to adapt to reaction liquids of different viscosities or densities and optimize the cavitation zone. The bolts also facilitate quick replacement or subsequent maintenance of the transducer.

[0010] Furthermore, the filtration unit includes a second motor, a top frame, a coupling, a threaded conveying rod, a filter box, a filter screen, and a conveying shell. The top frame is fixed to the top surface of the tank cover. Second motors are installed on both sides of the top surface of the top frame. The output shaft of the second motor is connected to the top end of the coupling, and the bottom end of the coupling is connected to the top end of the threaded conveying rod. The conveying shell is fixed to the bottom surface inside the tank. The threaded conveying rod is located inside the conveying shell. The discharge shell at the top of the outer side of the conveying shell is connected to the inlet on the side of the filter box. A filter screen is installed on the bottom surface inside the filter box. The input end of the second motor is electrically connected to the output end of the controller. Starting the second motor drives the threaded conveying rod to rotate, which, in conjunction with the conveying shell, pushes the solution into the filter box. The filter screen separates residue and solution in real time to reduce subsequent processing steps.

[0011] Furthermore, it also includes heating elements, a thermostat, and a temperature sensor. The heating elements are evenly installed at the four corners of the bottom surface of the can lid. The thermostat is fixed to the front side of the can body. The temperature sensor is installed on the surface of the can body. The input end of the heating element is electrically connected to the output end of the thermostat. The output end of the temperature sensor is electrically connected to the input end of the controller. The input end of the thermostat is electrically connected to the output end of the controller. The thermostat can adjust the temperature of the heating element to prevent overheating and decomposition during the refining of precious metals, while the temperature sensor can achieve precise temperature control.

[0012] Furthermore, it also includes a corrosion-resistant coating and a metal reflective layer. The metal reflective layer is disposed on the inner wall of the tank, and the surface of the metal reflective layer is uniformly coated with a corrosion-resistant coating. The metal reflective layer can reflect ultrasonic energy to improve utilization, while the corrosion-resistant coating can prevent the inner wall of the tank from being corroded and reducing its service life.

[0013] Furthermore, it also includes a wireless transmitter, which is fixed to the top surface of the top frame. The output of the wireless transmitter is electrically connected to the input of the controller. The wireless transmitter can remotely monitor reaction parameters (such as temperature and ultrasonic power) to facilitate data recording and process optimization.

[0015] 1. By activating the ultrasonic generator in conjunction with the transducer to generate high-frequency vibrations, a cavitation effect is created in the liquid, which significantly improves the mass transfer efficiency between precious metals and solvents. At the same time, the first motor drives the mixing rack to stir, thereby accelerating dissolution and chemical reactions. The generated ultrasonic waves can break up particle agglomerates, reduce precious metal residues, and improve the recovery rate.

[0016] 2. By starting the second motor, the threaded conveyor rod is rotated, which, together with the conveyor shell, pushes the solution into the filter box. The filter screen separates the residue and solution in real time to reduce subsequent processing steps.
