[0002] The molten pool smelting side-blown furnace is a kind of equipment commonly used in metal smelting and refining processes. It is mainly used for smelting metal, removing impurities and adjusting composition. The molten pool smelting side-blown furnace injects oxygen or other gases into the molten pool to produce a high-temperature combustion reaction during the smelting process, heating the metal and oxidizing and removing impurities, thereby achieving metal refining and alloy composition adjustment.

[0003] At present, the smelting furnace converter, which is mainly used to process the antimony-containing slag, bismuth slag and carbide slag, has been gradually phased out. Due to the limited processing capacity of antimony-containing slag, bismuth slag and carbide slag, it is not suitable for large-scale processing applications. In addition, due to the short distance between the feed port and the exhaust pipe of the current side-blown furnace, it is easy for the material to be discharged from the feed port into the furnace and be carried to the exhaust pipe by the flue gas produced by the combustion in the furnace, which causes serious waste of raw materials, makes the combustion in the furnace incomplete, and affects the production quality. Summary of the invention

[0004] The purpose of the embodiments of the present application is to provide an oxygen-enriched molten pool smelting side-blown furnace, which can solve the technical problem of reducing the waste caused by the material being carried out by the flue gas when it is input.

[0029] Reference Figure 1-4 A side-blown furnace for smelting oxygen-enriched molten pool comprises a furnace body 1, a water jacket 2 is arranged outside the furnace body 1, a feed pipe 11 and a smoke exhaust pipe 12 are arranged on the top of the furnace body 1, a separator 3 is arranged between the feed pipe 11 and the smoke exhaust pipe 12, the separator 3 is plugged and arranged on the top of the furnace body 1, and a plurality of fixing components 4 for fixing the separator 3 are also arranged on the top of the furnace body 1. When in use, the separator 3 is plugged into the top of the furnace body 1 to separate the top between the feed pipe 11 and the smoke exhaust pipe 12, so that the material will not be blocked by the smoke generated during the pouring process. And part of it is brought into the smoke exhaust pipe 12 for discharge, which can effectively separate the feed pipe 11 and the smoke exhaust pipe 12, and effectively prevent the newly poured material from being brought out from the smoke exhaust pipe 12, so that the material can be fully burned, the waste of material can be reduced, and the quality of the burned product can be guaranteed. At the same time, by plugging the partition 3 on the furnace body 1 and setting it through the fixing component 4, the replacement of the partition 3 can be effectively facilitated, and the stability of the partition 3 when used can be guaranteed, and the partition 3 can be prevented from loosening and affecting the airtightness of the furnace body 1.

[0030] Reference Figure 2 A contact plate 31 is provided on the partition 3, and a mounting groove 13 is provided on the furnace body 1. The contact plate 31 is embedded in the mounting groove 13. The arrangement of the contact plate 31 and the mounting groove 13 can better fix the partition 3 on the furnace body 1 to prevent the material of the furnace body 1 from colliding with the partition plate during use, causing shaking between the partition 3 and the furnace body 1, resulting in a gap that affects the sealing effect.

[0031] Reference Figure 2 A sealing gasket 131 is also provided in the mounting groove 13 , which can more effectively ensure the airtightness between the furnace body 1 and the partition 3 .

[0032] Reference Figure 2 A scraper 14 is provided inside the furnace body 1, and the scraper 14 abuts against the side wall of the partition 3. Through the setting of the scraper 14, the adhesive on the surface of the partition 3 can be cleaned when the partition 3 that needs to be replaced is taken out, so that the adhesive falls back into the furnace body 1.

[0033] Reference Figure 1-2 A lifting ring 32 is provided on the separator 3, and the setting of the lifting ring 32 can facilitate the lifting of the separator 3.

[0034] Reference Figure 3-4 The fixing assembly 4 includes a clamping plate 41, a mounting frame 42, a telescopic rod 43, a spring 44, a limit plate 45 and a handle 46. The clamping plate 41 is rotatably mounted on the top of the furnace body 1. The top of the clamping plate 41 is fixed to one end of the telescopic rod 43. The other end of the telescopic rod 43 is slidably connected to the mounting frame 42. The limit plate 45 is fixed on the telescopic rod 43. The upper end of the limit plate 45 is provided with card points around it. The upper end of the limit plate 45 is carded with the mounting frame 42. The lower end of the limit plate is carded with the spring. The spring 44 abuts against the clamping plate 41, and the other end of the spring 44 abuts against the clamping plate 41, and the top of the telescopic rod 43 is fixedly connected to the handle 46; when in use, by pressing the handle 46 downward, the upper end of the telescopic rod 43 can be moved downward, so that the limit plate 45 is disengaged from the mounting frame 42, and the handle 46 is rotated to rotate the handle 46, the clamping plate 41, and the limit plate 45, and control whether the clamping plate 41 is pressed against the abutting plate 31 on the partition 3, thereby fixing the partition 3.

[0035] More specifically, the separator 3 is a copper water jacket 2, which is a device for protecting the furnace, and is usually used in high-temperature smelting processes, especially in the field of metal smelting. The main function of the copper water jacket 2 is to reduce the temperature of the furnace wall by flowing cooling water, prevent the furnace from being eroded by high-temperature molten metal, and help maintain the stable working temperature of the furnace. The copper water jacket 2 is generally composed of an inner lining and an outer shell. The inner lining is close to the furnace wall and is made of copper or copper alloy with good thermal conductivity to effectively transfer the cooling effect of cooling water. The outer shell is wrapped around the inner lining to play a protective and supporting role. When the furnace is working, the cooling water circulates through the copper water jacket 2, which can effectively absorb and take away the heat of the furnace wall, ensure that the furnace wall temperature is within a safe range, prevent molten metal from damaging the furnace wall, and extend the service life of the furnace. In general, the copper water jacket 2 plays an important protective role in the high-temperature smelting process, can protect the furnace wall from the erosion of high-temperature molten metal, and ensure the normal operation and safe production of the furnace.

For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
