1. Single impeller leaching agitation tank Designed by China Nonferrous Metals Institute, the single impeller leaching agitation tank, also known as axial flow leaching agitation tank, is suitable for large relative density, high viscosity, fast settling speed, ore fineness -200 head more than 85%, gold leaching, adsorption and other mixing pulp density of less than 45% of the mixing work.
The working principle of the agitation tank is shown in Fig. 1. When the impeller rotates clockwise (from the top to the bottom), the blades immersed in the slurry exert a pushing and squeezing effect on the slurry, so that the slurry flows into the blade from the upper part of the circulation cylinder. The guide vanes flow downward along the circulation cylinder. When the slurry passes through the circulation cylinder, it flows laterally, then flows upward along the outer wall of the circulation cylinder, and then returns to the upper part of the circulation cylinder to form a closed loop. As the new slurry continues to be fed into the tank, the qualified slurry which is thoroughly mixed with the agent and air is continuously discharged from the discharge port (overflow port), thereby completing the leaching operation of the tank.
The characteristics of the single impeller leaching agitation tank are as follows: 1 small power consumption, large axial velocity, small radial velocity, large stirring intensity, good mixing effect; 2 impeller is above the “slurry sedimentation zoneâ€, the boot is light, so the starting power is small. The working strength of the operator is greatly reduced; 3 the inflatable device has a simple structure, uniform inflation, sufficient mixing of air and slurry; 4 large effective volume, small footprint; 5 low impeller circumferential speed and long service life; 6 impeller blade mounting angle Variable, can meet the requirements of different production processes.
The technical parameters of the single impeller leaching agitation tank are listed in Table 1.
The single impeller leaching agitation tank produced by various mines is also called cyanide agitation tank, which is used for cyanidation and agitating pulp. At present, it mainly produces a specification (Φ3500×3500) cyanide stirred tank. The main technical parameters are listed in Table 2. The external dimensions are shown in Figure 2.
2. dual impeller stirred tank leaching of gold processing plant in the 1970s before the main single impeller stirred tank leaching, with the rapid development of China's gold mining industry, the Chinese colored homes and other units reference equipment imported from abroad and learn The production practice experience of domestic leaching agitation tank has successfully developed SJ type double impeller leaching agitation tank and other equipment, which has been widely used in production and has good effect. In the past 10 years, the specifications of the double impeller leaching agitation tank have been gradually expanded, from 5m in diameter and 5.6m in height to 8m in diameter and 8.5m in height. The maximum diameter has reached 10m and the maximum height is 10.5m. At the same time, its structure and performance are constantly increasing. Improve.
SJ type double impeller leaching agitation tank is mainly produced by Xinhai Mining Machinery, Jilin Province Prospecting Machinery Factory (hereinafter referred to as Jilin Prospecting), Inner Machinery and Shandong Rushan Gold Machinery Factory (hereinafter referred to as milk machine). The model specifications are the same, the equipment size The same, that is, all made with the same drawings.
The series of agitation tanks are used for mixing leaching and carbon adsorption of gold cyanide plant with a fineness of -200 mesh of more than 900.6 and a concentration of less than 45%. It can also be used for mixing and leaching operations under the corresponding conditions of metallurgy, chemical industry and light industry. .
The working principle is (Fig. 3): the slurry flows from the top to the bottom in the center under the push and agitation of the double impeller, and then diffuses through the peripheral damper plate, and air is fed at the lower end of the shaft (air is given by the hollow shaft) In) mixed with the slurry and circulated upward to form a homogeneous suspension mixture.
The characteristics of the SJ double impeller leaching agitation tank are as follows: 1 the ore flow is stable, the slurry is evenly mixed, and the power consumption is low; 2 the air enters the tank through the hollow shaft of the transmission, and the air is evenly dispersed by the impeller; 3 compact structure and convenient maintenance; 4 impeller lining rubber, low peripheral speed, long service life; 5 reducer has three forms: flat envelope worm drive, ordinary worm drive, needle pendulum reducer, available for users to choose.
The technical parameters of the SJ type double impeller leaching agitation tank produced by various mines, internal machines and milk machines are listed in Table 3. The outline and installation dimensions are shown in Fig. 4 and Table 4.
Qunying produces QC type double impeller leaching agitation tank. There are two kinds of specifications. The main technical parameters are listed in Table 5. The external dimensions are shown in Figures 5 and 6. The equipment is mainly used for cyanide leaching operation and slurry mixing operation under the condition that the slurry concentration is not more than 45% and the ore particles are not more than 0.5 mm.
The structure, working principle and external dimensions of the double impeller leaching agitation tank produced by Zhaoyuan Huangji General Factory are basically the same as those of the SJ type double impeller leaching agitation tank. The specifications and technical parameters are listed in Table 6.
The JC type leaching tank produced by Liaozhong and its technical parameters are listed in Table 7.
The double impeller high-efficiency leaching agitation tank produced by Xinhai Mining Machine can also be used as adsorption agitation tank. It is characterized by reasonable structure, compact structure and high transmission efficiency. It adopts two new impellers with large impeller diameter, low rotation speed and low stirring power consumption. The wear of the carbon can be reduced, the hollow shaft is ventilated to the bottom end, the air is uniformly dispersed, and the air bubbles are small. The mixing intensity is moderate, and the slurry concentration and fineness distribution in the tank are basically the same, which can increase the leaching rate of cyanide and the adsorption rate of carbon. The company has improved the aeration system and transmission system of the leaching (adsorption) tank.
The technical performance of the double impeller high-efficiency leaching (adsorption) stirred tank produced by the company is shown in Table 8.
The double impeller leaching tank produced by Dahua Heavy Machinery is mostly used for cyanide leaching and cyanide plant wastewater treatment in gold production. It is suitable for pulp with a specific gravity of about 1.4, a fineness of about 200 mesh, and a concentration of less than 45%. It is also suitable for mixing and mixing operations under the corresponding conditions of metallurgy, chemical industry and light industry. The machine has the characteristics of high efficiency, energy saving, uniform mixing, simple structure and convenient maintenance. The technical parameters are shown in Table 9.
JJCA series energy efficient leaching tank. The JJCA series high-efficiency energy-saving leaching tank for Jilin prospecting production is mostly used for cyanide leaching and cyanide plant sewage treatment in gold mine production. It is suitable for specific gravity of 1.4, fineness of -200 mesh for more than 90%, and concentration of less than 45%. Mineral pulp.
