Technical Field
[0001] This utility model relates to the field of metallurgical equipment technology, and in particular to an isothermal high-efficiency pyrometallurgical equipment. Background Technology
[0002] Metallurgy is an important process that extracts metals or metal compounds from minerals under high-temperature conditions and processes them into metallic materials. High-temperature smelting is the core step in this process; by smelting minerals at high temperatures, impurities can be effectively removed, resulting in high-purity metallic products.
[0003] To achieve high-temperature smelting in pyrometallurgy, sufficient fuel must be supplied to the furnace to ensure a stable heat supply. However, in existing pyrometallurgical equipment, the charging process is often accompanied by a large outflow of heat and heat loss from the furnace. This can not only lead to an increase in the working environment temperature but also pose safety hazards such as burns to operators, thus seriously affecting the smooth progress of the charging operation.
[0004] Therefore, an isothermal high-efficiency pyrometallurgical equipment is proposed to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide an isothermal high-efficiency pyrometallurgical equipment, which solves the aforementioned technical problems.

[0007] Preferably, the surface of the heat insulation column is fixed with a plurality of clips, the feeding column is provided with a slot, the clips are elastically engaged with the inner wall of the slot, and handles are fixedly sleeved at both ends of the heat insulation column.
[0008] Preferably, a transfer pipe is detachably installed at the end of the exhaust pipe, and a water tank is fixedly installed through the end of the transfer pipe away from the exhaust pipe. A heating pipe is fixedly installed inside the water tank, and the heating pipe is connected to the end of the transfer pipe. A valve is opened through the lower end of the water tank.

[0012] Compared with related technologies, the isothermal high-efficiency pyrometallurgical equipment provided by this utility model has the following beneficial effects:
[0013] This utility model provides an isothermal high-efficiency pyrometallurgical equipment. During the smelting process, the materials to be added are fed into the feeding port and then fall into the transfer trough. The heat insulation column is then rotated to change the direction of the transfer trough opening. When the opening of the transfer trough is aligned with the through channel at the bottom, the materials inside the transfer trough fall into the furnace body through the through channel, thus completing the material addition. While ensuring normal feeding, it can prevent the heat inside the furnace from surging out and burning the workers. At the same time, during the feeding process, it does not come into contact with the external environment, thereby maintaining the stability of the internal temperature of the equipment body, avoiding a reduction in smelting quality, and improving smelting efficiency.

The gas generated by combustion inside the main body of the equipment is discharged through the exhaust pipe and introduced into the heating tube through the transfer pipe. The waste heat of the gas is used to heat the water inside the water tank, which can realize the effective utilization of resources and reduce resource waste. The water tank is drained and injected through the valve. Attached Figure Description

Detailed Implementation
[0020] Please see Figures 1-4 This utility model provides a technical solution, including a main body 1, which is composed of a furnace body 11 and a furnace cover 12. A feeding column 13 is fixedly installed through the top of the furnace cover 12. A heat insulation column 18 is rotatably installed through the surface of the feeding column 13. A feeding port 17 is vertically opened through the top of the feeding column 13. A material transfer groove 22 is recessed in the surface of the heat insulation column 18. The feeding port 17 is connected to the inner wall of the material transfer groove 22. A through groove 23 is opened through the bottom of the feeding column 13. The through groove 23 is connected to the inner wall of the feeding port 17. An exhaust pipe 16 is opened through the surface of the furnace cover 12.
[0021] During the smelting process of the main body of the equipment 1, the materials to be added are fed into the feeding port 17 and then fall into the transfer trough 22. Then, the heat insulation column 18 is rotated to change the direction of the opening of the transfer trough 22. When the opening of the transfer trough 22 is rotated to the bottom and aligned with the through trough 23, the materials inside the transfer trough 22 fall into the furnace body 11 through the through trough 23, thus completing the addition of materials. While ensuring normal feeding, it can prevent the heat inside the furnace body 11 from surging out and burning the workers. At the same time, during the feeding process, it does not come into contact with the external environment, thereby maintaining the stability of the internal temperature of the main body of the equipment 1, avoiding the reduction of smelting quality, and improving smelting efficiency.
[0022] Several clips 21 are fixedly provided on the surface of the heat insulation column 18, and the feeding column 13 is provided with a slot 2. The clips 21 are elastically engaged in the inner wall of the slot 2, and handles 19 are fixedly sleeved at both ends of the heat insulation column 18.
[0023] During the process of rotating the heat insulation column 18 by holding the handle 19, the elastic engagement between the clamp head 21 and the clamp slot 2 creates a certain resistance in the heat insulation column 18, which keeps it stable when the transfer trough 22 is stationary, thereby improving the smelting stability of the main body of the equipment 1.
[0024] A transfer pipe 14 is detachably installed at the end of the exhaust pipe 16. A water tank 15 is fixedly installed at the end of the transfer pipe 14 away from the exhaust pipe 16. A heating pipe 25 is fixedly installed inside the water tank 15. The heating pipe 25 is connected to the end of the transfer pipe 14. A valve 3 is opened through the lower end of the water tank 15.
[0025] The gas generated by combustion inside the main body of the equipment 1 is discharged through the exhaust pipe 16 and introduced into the heating pipe 25 through the transfer pipe 14. The waste heat of the gas is used to heat the water inside the water tank 15, which can realize the effective use of resources and reduce resource waste. The valve 3 is used to discharge and inject water into the water tank 15.
[0026] The top of the water tank 15 is sealed with a tank cover 24. A filter plate 28 is detachably installed on the inner wall of the tank cover 24. An exhaust port 29 is opened through the top of the tank cover 24, and a through hole 26 is opened through the bottom of the tank cover 24. The end of the heating tube 25 away from the transfer tube 14 is fixedly sleeved on the inner wall of the through hole 26.
[0027] High-temperature gas is introduced into the box cover 24 through the through hole 26 inside the heating tube 25, and the impurities in the gas are adsorbed on the surface of the filter plate 28 by the filter plate 28, thereby reducing the pollution to the surrounding environment after the gas is discharged.
[0028] The heating element 25 is arranged in an S-shape inside the water tank 15;
[0029] Extending the residence time of high-temperature gas inside water tank 15 further improves resource utilization and reduces heat loss.
[0030] The inner diameters of the inner walls of the feeding port 17, the transfer trough 22, and the through trough 23 are the same.
[0031] This allows the material fed into the transfer trough 22 through the feeding port 17 to be completely transferred into the furnace body 11 through the channel 23.
