Description

Technical Field

[0001] The present application relates to the technical field of smelting converters, and in particular to a feed converter for smelting lead. Background Art

[0002] In the past, the world has widely adopted the molten pool smelting technology to process lead sulfide concentrate. Its characteristic is that it uses oxygen-enriched or pure oxygen to strengthen the smelting. Due to the reduction of flue gas volume, the concentration of sulfur dioxide in the flue gas is greatly increased. Compared with the traditional smelting method, the environmental pollution problem has been basically solved, and the clean production of lead has become a reality.

[0003] At present, when the proportion of raw materials entering the furnace is adjusted, because other high-rich materials are matched, the particle size of the ball material 8-10mm needs to reach more than 80% during the granulation process. Therefore, the moisture content of the ball material is strictly monitored during the operation, and it is immediately processed if it does not meet the requirements. However, in the process of adding water, the operation process is complicated, and it is easy to make the moisture content of the raw materials in the converter uneven, resulting in poor granulation effect. In addition, because the raw materials are in a wet state and are turned over in the furnace, it is difficult to discharge the raw materials from the furnace, which directly affects the vertical yield. Summary of the invention

[0027] The embodiment of the present application discloses a feed converter for smelting lead.

[0028] Reference Figure 1-3 A feed converter for smelting lead comprises a base 1, on which a driving assembly 2, a furnace body 3, a feed rack 4 and a discharge rack 5 are arranged, the driving assembly 2 drives the furnace body 3 to rotate, the feed rack 4 is sleeved at the feed end of the furnace body 3, and the feed rack 4 is connected to a feed pipe 41, the discharge rack 5 is sleeved at the discharge end of the furnace body 3, and a discharge port 51 is arranged at the lower end of the discharge rack 5;

[0029] The diameter of the furnace body 3 increases from the feeding end to the discharging end, and a spray assembly 6 is arranged in the furnace body 3, and the spray assembly 6 is fixedly arranged on the discharging frame 5;

[0030] When in use, the furnace body 3 is rotated and arranged between the feed rack 4 and the discharge rack 5, and the raw materials are discharged into the furnace body 3 from the feed pipe 41. The driving component 2 drives the furnace body 3 to rotate, so that the raw materials are mixed in the furnace body 3. At the same time, the spray component 6 in the furnace body 3 replenishes water for the raw materials in time. After the raw materials rotate in the furnace body 3 for a certain period of time, they are discharged through the discharge port 51. The spray component 6 is arranged in the furnace body 3, so that the raw materials can be replenished with water in time and effectively, and the uniformity of the water replenishment can be guaranteed. In addition, the diameter of the tube from the feed end to the discharge end of the furnace body 3 is gradually increased, which can effectively prevent the raw materials from being unable to be discharged normally from the furnace body 3 due to wetting.

[0031] Reference Figure 2-3 The spray assembly 6 includes a water pump 61, a water injection pipe 62 and a plurality of spray nozzles 63. The water pump 61 is fixedly arranged on the discharge rack 5, the water injection pipe 62 is fixedly arranged on the discharge rack 5, and the water injection pipe 62 extends into the furnace body 3. A plurality of spray nozzles 63 are connected and arranged at the lower end of the water injection pipe 62. When in use, the water intake is controlled by the water pump 61, so that the spray nozzles 63 on the water injection pipe 62 can evenly replenish water in the furnace body 3.

[0032] Reference Figure 2-3 The discharge rack 5 is also provided with an exhaust port 52 and an observation door 53. The exhaust port 52 is communicated with the furnace body 3, and the observation door 53 is rotatably installed under the discharge rack 5. When in use, the exhaust port 52 can appropriately reduce the air pressure in the furnace body 3, and the observation door 53 can effectively facilitate the staff to observe the situation in the furnace.

[0033] Reference Figure 2-3 A shaking motor 511 is fixedly arranged below the discharge port 51, which can effectively prevent the discharge port 51 from being blocked by materials, and effectively shake off the materials on the discharge port 51 through vibration.

[0034] Reference Figure 1The driving assembly 2 includes an external gear 21, a driving gear 22 and a servo motor 23. The servo motor 23 is fixedly arranged on the base 1. The servo motor 23 drives the driving gear 22 to rotate. The external gear 21 is fixed to the outer wall of the furnace body 3. The external gear 21 is meshed with the driving gear 22. When in use, the servo motor 23 drives the driving gear 22 to rotate. The rotation of the driving gear 22 drives the external gear 21 to rotate, so that the furnace body 3 rotates.

[0035] Reference Figure 1 The base 1 is also provided with a plurality of rotating wheels 11 abutting against the furnace body 3. The setting of the rotating wheels 11 can effectively reduce the support of the feed rack 4 and the discharge rack 5 on the furnace body 3, and effectively prevent the furnace body 3 from deflecting during the rotation process.

[0036] Reference Figure 3 A scraper 31 is also fixed between the feed rack 4 and the discharge rack 5. The scraper 31 contacts the top of the inner wall of the furnace body 3. When in use, the scraper 31 is used to scrape off the raw materials on the top of the inner wall of the furnace body 3, which can effectively prevent the raw materials from adhering to the inner wall of the furnace body 3 and being unable to be discharged.
