Abstract
Description
Technical Field
[0001] The invention relates to the technical field of rare earth smelting, and in particular to a pyrometallurgical smelting device for rare earth smelting. Background Art
[0002] Rare earth is a general term for 17 kinds of metal elements including lanthanide elements, scandium and yttrium in the periodic table. There are 250 kinds of rare earth minerals in nature. Among the rare earth ores mined all over the world, the rare earth oxide content is only a few percent, and some are even lower. In order to meet the production requirements of smelting, rare earth minerals are separated from gangue minerals and other useful minerals through ore dressing before smelting to increase the content of rare earth oxides and obtain rare earth concentrates that can meet the requirements of rare earth metallurgy. After the rare earth concentrate is refined, there are still a lot of minerals inside the rare earth, and its purity is still relatively low, so it needs to be further smelted by smelting equipment.
[0003] There are two methods for rare earth smelting, hydrometallurgy and pyrometallurgy. Among them, pyrometallurgy has a relatively simple process and high productivity. It is the main method of rare earth smelting at present. The main feature of pyrometallurgy is that smelting is carried out under high temperature conditions. In the existing technology, there are relatively more smelting equipment when pyrometallurgical smelting rare earths. Smelting equipment is generally referred to as metallurgical furnaces. According to different heat sources, it can be divided into three categories: fuel furnaces, electric furnaces, and self-heating furnaces. Among them, the medium frequency furnace in the electric furnace is a commonly used equipment for rare earth pyrometallurgy in modern small and medium-sized enterprises due to its small size, light weight, high efficiency, and excellent thermal processing quality. When smelting rare earths, the equipment first places the rare earths and the materials for thermal reduction with them inside the furnace core barrel of the smelting equipment, and then places the furnace core barrel inside the medium frequency furnace to heat it, and extracts the rare earths through high-temperature thermal reduction. Although this equipment has many advantages, it still has the following problems in actual use. When smelting rare earths, the thermal reduction process of rare earths will produce A large amount of smoke and dust is difficult to fully absorb when the smoke is absorbed by purchased smoking and dust collection equipment, which can easily cause pollution to the production workshop and seriously affect the personal health of production personnel. At the same time, the existing medium frequency furnace is not convenient for timely and rapid removal of the furnace core barrel inside the medium frequency furnace after smelting rare earths, and external equipment is required for assistance. After the furnace core barrel is taken out, it is not convenient to quickly smelt other rare earths to be smelted, which wastes a lot of heat energy inside the medium frequency furnace and causes waste of resources. For this reason, we propose a pyrometallurgical smelting equipment for rare earth smelting. When the equipment is used for pyrometallurgical smelting of rare earths, it is not only convenient to fully absorb the smoke generated during the smelting process to ensure the air quality of the workshop, but also convenient to quickly remove the furnace core barrel after smelting the rare earths, and convenient to quickly place the rare earths to be smelted in the smelting equipment, which greatly reduces the loss of heat, and also improves the smelting efficiency, and has high applicability.

At the same time, through the cooperation of the temperature control baffle 22 on the dust collecting cover 21, it is convenient to block and keep the stability of the inside of the smelting equipment body 1 to a certain extent, so as to prevent excessive heat loss inside the smelting equipment body 1;
[0033] It should be further explained that the material taking device includes two groups of material taking mechanisms 203, both of which are arranged on the carrier 4, and both of which are located above the motion bearing mechanism 201 and on both sides of the dust collecting mechanism 202. The material taking mechanism 203 includes a material taking group 103 and a second driving group 104, and the material taking group 103 includes a material taking plate 25, which is slidably mounted on the carrier 4, and an electric cylinder 26 is installed on the material taking plate 25, and the output end of the electric cylinder 26 A material taking frame 27 is fixedly installed on the bottom of the material taking plate 25, and two steel wire ropes 28 are fixedly installed on the material taking frame 27. The other ends of the two steel wire ropes 28 are fixedly installed with hooks 29. The two hooks 29 correspond to the two lifting rings 3 respectively. By starting the electric cylinder 26, the smelting material loading barrel 2 inside the smelting equipment body 1 can be taken out through the hook 29. The second driving group 104 includes a tooth plate 2 30 and a machine base 31. The tooth plate 2 30 is fixedly installed on the bearing frame 4, and the machine base 31 is fixedly connected to the material taking plate 2 5, a driving motor 2 32 is installed on the base 31, a gear 33 is fixedly installed on the output end of the driving motor 2 32, the gear plate 2 30 is meshed with the gear 33, and two protection boxes 36 for protecting the gear plate 2 30 and the gear 3 33 are also provided on the carrier 4, and a conveying through hole 2 is opened on the two protection boxes 36, and the output end of the driving motor 2 32 is located inside the conveying through hole 2.

A certain protection is performed, and at the same time, by starting the driving motor 2 32, the smelting loading barrel 2 is driven to move through the material taking plate 25, and the smelted rare earth is taken out through the material taking mechanism 203 on one side, and then the smelting loading barrel 2 and the rare earth to be smelted are put back into the smelting equipment body 1 through the cooperation between the material taking mechanism 203 on the other side and the motion supporting mechanism 201, and the next wave of smelting can be carried out on it, thereby improving the smelting efficiency and correspondingly reducing the heat loss inside the smelting equipment body 1.
[0034] It is to be noted that the drive motor 10, the drive motor 2 32 and the exhaust fan 19 in the present embodiment are all existing equipment known to those skilled in the art and purchased on the market.

When the position sensor 8 corresponds to the sensor block 9, the smelting equipment body 1 is just located below the dust collecting mechanism 202 and the two material taking mechanisms 203. The dust collecting hood 21, the temperature control baffle 22, and the dust collecting hose 20 are all made of high temperature resistant materials, and through the barrier of the temperature control baffle 22, the temperature of the hot flue gas will drop sharply after passing through the dust collecting hose 20, which is not easy to affect the service life of the exhaust fan 19. According to actual conditions, the distance between the exhaust fan 19 and the dust collecting hood 21 can also be adjusted and installed.
[0035] In summary, when the pyrometallurgical smelting equipment for rare earth smelting performs pyrometallurgical smelting on rare earth, the rare earth to be smelted and the material to be thermally reduced therewith are placed inside the smelting loading barrel 2, and the driving motor 2 32 on one side is started. The positive and reverse rotations corresponding to the driving motor 2 32 are selected according to the position of the one side, so that the output end of the driving motor 2 32 drives the gear 33 to rotate, and the movement of the gear 33 on the tooth plate 2 30 drives the driving motor 2 32 to move, so that the driving motor 2 32 drives the machine base 31 to move, and the machine base 31 drives the material taking plate 25 to move, so that the material taking plate 25 drives the smelting loading barrel 2 below it to move to one side of the carrier 4, and this position is the upper The smelting material loading barrel 2 is hung on the hook 29 of the material taking mechanism 203 through the lifting ring 3 on the external device, and then the driving motor 2 32 is started to drive the rare earth to be smelted and the smelting material loading barrel 2 to move to the material discharging position through the material taking plate 25, and then the driving motor 10 is started. According to the position of the smelting material loading barrel 2, the forward or reverse rotation of the driving motor 10 is selected, so that the output end of the driving motor 10 drives the gear 11 to rotate, and the gear 11 drives the gear 2 14 meshing with it to rotate, and the gear 2 14 drives the driving rod 13 to rotate, and the driving rod 13 drives the gears 2 14 on both sides thereof to rotate, so that the gear The gear 14 moves on the tooth plate 15, and the movement of the gear 14 makes the driving motor 10 move. The movement of the driving motor 10 drives the carrying plate 5 to move. The slides 6 on both sides of the carrying plate 5 move on the corresponding slide bars 7. The movement of the carrying plate 5 can drive the position of the smelting equipment body 1 to move. When the position sensor 8 on the slide 6 coincides with the induction block 9 on one side of the smelting material loading barrel 2, the position sensor 8 transmits the information to the driving motor 10, and the driving motor 10 stops. At this time, the smelting equipment body 1 is located below the discharge position of the material taking mechanism 203, and the electric cylinder 26 is started. The output of the electric cylinder 26 The outlet drives the material taking frame 27 to move, the material taking frame 27 drives the steel wire rope 28 to move, the steel wire rope 28 drives the hook 29 to move, and the smelting material loading bucket 2 is placed inside the smelting equipment body 1 through the hook 29, and then the hook 29 is removed from the lifting ring 3 by manual and external device cooperation, such as a long-handled clip, and then the drive motor 10 is started to drive the smelting equipment body 1 to move to the bottom of the dust collecting mechanism 202. Similarly, through the cooperation between the position sensor 8 and the corresponding sensor block 9, the position sensor 8 transmits information to the drive motor 10 to stop the movement, and the position of the smelting equipment body 1 is accurately located;
[0036] Furthermore, when the smelting equipment body 1 moves to the bottom of the dust collecting mechanism 202, the smelting equipment body 1 is opened to perform pyrometallurgical smelting on the rare earth inside the smelting loading bucket 2, and at the same time, the electric cylinder 24 is started, and the output end of the electric cylinder 24 drives the dust collecting plate 23 to move, and through the extension and contraction of the dust collecting hose 20, one end of the dust collecting cover 21 moves to the inside of the groove on the smelting equipment body 1, and then the exhaust fan 19 is started. The wind force of the exhaust fan 19 can also be adjusted according to the flue gas generated by the smelting of the rare earth by the smelting equipment body 1. When the smelting equipment body 1 is smelting the rare earth, less flue gas is generated in the initial stage of smelting, and a large amount of flue gas and dust will be generated in the middle stage of smelting. After the end of the late stage of smelting, the generation of flue gas will decrease accordingly. The flue gas extracted by the exhaust fan 19 is purified by external equipment and discharged after meeting the national emission standards. After the rare earth is smelted by pyrometallurgy, according to the above-mentioned smelting method, by closing the exhaust fan 19, and then starting the electric cylinder 24 to move the dust hood 21 to the position before smelting, the rare earth will no longer or only produce a small amount of smoke after smelting, and it is not easy to cause harm to the environment of the workshop or the body of the staff. Then, through the cooperation between the motion bearing mechanism 201 and the material taking mechanism 203 on one side, the smelting loading barrel 2 that has been smelted inside the smelting equipment body 1 is taken out, and then the smelting equipment body 1 is moved to the material taking mechanism 203 on the other side, and the next wave of rare earth to be smelted is placed thereon, and then smelting can be resumed. At the same time, the smelted rare earth and the smelting loading barrel 2 are removed by external equipment, and then the next step of purification is carried out to complete the pyrometallurgy. Compared with the existing smelting equipment, the smelting efficiency of the smelting equipment is relatively high and the practicality is high.
