[0033] The existing rotary furnace structure requires oxygen guns, fuel guns, etc. to extend from the furnace mouth into the furnace cavity, so that the furnace mouth is generally open. During the smelting process, waste gas overflows from the furnace mouth, causing air pollution and a poor smelting environment.

[0034] In view of this, the present invention proposes a multifunctional refining furnace, please refer to Figures 1 to 4 , is an embodiment of the multifunctional refining furnace proposed in this application, and the multifunctional refining furnace will be described in detail below with reference to specific drawings.

[0035] See also Figures 1 to 4 The multifunctional refining furnace 100 comprises a base 1, a rotating bracket 2, a heating furnace assembly 3 and a cover 4, wherein the base 1 has a first end and a second end in a first horizontal direction; the rotating bracket 2 can be rotatably mounted on the base 1 around a second horizontal direction, and during the rotation process from the first end to the second end, a loading position, a working position and a discharging position are sequentially provided; the heating furnace assembly 3 comprises a furnace body 31 mounted on the rotating bracket 2 and a driving assembly 32, wherein the furnace body 31 can be rotatably mounted on the rotating bracket 2, and the driving assembly 32 is used to drive the furnace body 3 1 rotates on the rotating bracket 2, and in the loading position and the working position, the furnace mouth of the furnace body 31 is arranged upward, and in the unloading position, the furnace mouth of the furnace body 31 is arranged downward; the cover body 4 is movably arranged on one side of the furnace body 31, and has a covering position at the furnace mouth of the furnace body 31 at the working position and a avoiding position away from the furnace body 31 in its movable stroke, and a heating component and a smoke exhaust device are arranged on the cover body 4, the heating end of the heating component is extended into the furnace body 31, and the smoke exhaust pipe 43 of the smoke exhaust device is extended outward.

[0036] In the technical solution of the present invention, the multifunctional refining furnace 100 mainly includes the rotating bracket 2 rotatably installed on the base 1, and the heating furnace assembly 3 is installed on the rotating bracket 2, so that during the rotation of the rotating bracket 2, the furnace body 31 in the heating furnace assembly 3 can be driven to rotate and switch between the loading position, the working position and the unloading position. At the same time, the heating furnace assembly 3 includes the furnace body 31 and the driving assembly 32. The driving assembly 32 is used to drive the furnace to rotate around its own axis on the rotating bracket 2, so that when the furnace body 31 is working, it can be driven to rotate, so that the internal mixing is more sufficient, the heating is more uniform, and the smelting quality is improved. On this basis, the nozzle of the furnace body 31 is used for loading and unloading materials and extends into the heating component during operation to heat the materials in the furnace body 31. In this state, the nozzle of the furnace body 31 is open, and there is a problem of smoke overflow and environmental pollution. Therefore, the present application is provided with a movable cover body 4 on one side of the base 1. By covering the cover body 4 at the nozzle of the furnace body 31 and arranging the smoke exhaust device on the cover body 4, on the one hand, the cover body 4 covers the nozzle of the furnace body 31 to reduce the open area of ​​the nozzle of the furnace body 31, and on the other hand, the smoke is discharged by the smoke exhaust device, which further reduces the smoke overflow and meets the functional requirements. At the same time, the heating component is also installed on the cover 4 to extend into the furnace body 31 to heat the furnace body 31. Combined with the cover 4 covering the furnace nozzle, a nearly closed structure is formed in the furnace body 31, so that the furnace body 31 can be heated to a higher temperature to meet the refining requirements with higher temperature requirements, so as to adapt to a variety of refining scenarios, meet the use characteristics of multi-functional scenarios, and improve its applicability. At this time, according to the maximum temperature that can be reached in the furnace body 31, the material of the furnace body 31 is selected as an adapted high-temperature resistant material to meet the high-temperature resistance requirements. The cover 4 can be movably arranged so that the cover 4 can drive the heating component and the smoke exhaust device to avoid the rotation of the furnace body 31 to meet the requirements of rotating loading and unloading of the furnace body 31. In addition, after the cover 4 is provided, the cover 4 also plays a role in preventing splashing, so as to prevent the refined materials in the furnace body 31 from being sprayed out through the furnace nozzle of the furnace body 31 after heating reaction, and has a certain protective effect.

[0037] It can be understood that the furnace body 31 needs to rotate around its axis during operation to mix the internal materials evenly, which has been described above. On this basis, the cover body 4 covering the furnace nozzle of the furnace body 31 can be rotated synchronously with the furnace body 31, but the heating component and the smoke exhaust device are also provided on the cover body 4, which are not convenient to rotate. Therefore, in some embodiments, a rotatable ring can be provided on the outer edge of the cover body 4 so that the ring covers the furnace nozzle of the furnace body 31, and the ring rotates with the furnace body 31, while the main body of the cover body 4 does not rotate, so as to meet the structural setting of the heating component and the smoke exhaust device. Although this setting method ensures that the cover body 4 and the furnace body 3 1 to reduce smoke overflow, but the structural design is obviously complex and costly, so in this embodiment, it is directly set that the cover body 4 and the furnace nozzle of the furnace body 31 are spaced apart so that there is no fit between the cover body 4 and the furnace body 31. When the furnace body 31 rotates, the cover body 4 can remain in a static state normally to meet the structural and functional requirements. The gap size between the cover body 4 and the furnace body 31, on the one hand, needs to avoid being too large to cause more smoke overflow, and on the other hand, needs to avoid being too small to cause the cover body 4 to contact with the furnace body 31. In this embodiment, the spacing between the cover body 4 and the furnace nozzle of the furnace body 31 is set to between 10 mm and 20 mm to meet the above requirements.

[0038] In addition, the specific installation method of the cover body 4 is not limited in the present application. It can be hoisted on the top of the furnace body 31 through a hoisting structure, or it can be installed on the side of the furnace body 31 through a telescopic structure, so that the cover body 4 can be moved between the covering position and the avoidance position, and it is convenient to install the heating component and the smoke exhaust device. In this embodiment, a support seat 5 is provided on one side of the base 1, and a support arm 51 is rotatably provided on the support seat 5. The cover body 4 is installed on the free end of the support arm 51, and the support arm 51 rotates to drive the cover body 4 to move between the covering position and the avoidance position. The cover body 4 is supported by the support seat 5, so that the movement of the cover body 4 is more stable, and the main body of the heating component and the smoke exhaust device can be directly set on the support surface, connected to the cover body 4 by a connecting structure, which is convenient for the installation of the heating component and the smoke exhaust device.

[0039] Specifically, the heating assembly includes a fuel pipe 41, an oxygen pipe 42 and a burner. The burner is installed on the side of the cover body 4 facing the furnace body 31 and extends into the furnace body 31. The fuel pipe 41 and the oxygen pipe 42 are located on the side of the cover body 4 away from the furnace body 31 to connect the burner. The specific structural arrangement of the heating assembly is not limited, and it is sufficient to heat the furnace body 31 and the temperature can reach the required smelting temperature. For example, it can be a fuel gun and an oxygen gun that are independently arranged from the cover body 4 and extend into the furnace body 31 through the cover body 4. In this embodiment, a burner installed on the cover body 4 is mainly provided, which is connected by the fuel pipe 41 and the oxygen pipe 42, so that the burner can move with the cover body 4 and extend into the furnace body 31, without the need for an additional actuating mechanism, thereby simplifying the operation.

[0040] In addition, it can be understood that the multifunctional refining furnace 100 is used to smelt different materials, and the required temperatures may be different, so that the fuel transported in the fuel pipe 41 and the oxygen content transported in the oxygen pipe 42 are also different. For different fuels, the oxygen mixing ratio required for their full combustion is different, so that the channel size ratios corresponding to the fuel pipe 41 and the oxygen pipe 42 on the burner are different. In view of this, this embodiment also proposes to detachably install the burner on the cover body 4, so as to facilitate the replacement of different burners for different smelting scenarios. It should be noted here that, based on the structural feature that the cover body 4 covers the furnace nozzle of the furnace body 31 to almost close the furnace body 31, the fuel transported in the fuel pipe 41 can be natural gas, so that the temperature in the furnace body 31 can be heated to a higher level, up to 3000 degrees Celsius, to meet the high-temperature refining requirements and the multifunctional use nature of the multifunctional refining furnace 100. Similarly, in order to meet the high temperature resistance requirements, the material of the burner extending into the furnace body 31 should also be selected to be suitable for the highest temperature that can be reached in the furnace body 31.

[0041] In addition, an exhaust device 6 is provided at the exhaust end of the smoke exhaust pipe 43. Based on the arrangement of the smoke exhaust pipe 43 on the cover body 4, the smoke can be gathered by the smoke exhaust pipe 43 and guided to its exhaust end for discharge. In this embodiment, the exhaust device 6 is also provided at the exhaust end of the smoke exhaust pipe 43 to further improve the smoke exhaust performance, avoid smoke overflow, and meet the structural and functional requirements.

[0042] See also Figure 1The present invention further proposes a multifunctional refining system 1000, which includes a loading device 200, a receiving vessel 300 and the multifunctional refining furnace 100. The specific structure of the multifunctional refining furnace 100 refers to the above embodiment. Since the multifunctional refining system 1000 adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which are not repeated here one by one; the loading device 200 is arranged at the first end of the base 1, and when the rotating bracket 2 is located at the loading position, the furnace nozzle of the furnace body 31 is arranged corresponding to the discharge end of the loading device 200; the receiving vessel 300 is arranged at the second end of the base 1, and when the rotating bracket 2 is located at the unloading position, the furnace nozzle of the furnace body 31 is arranged corresponding to the receiving vessel 300.

[0043] Specifically, according to the structural and functional requirements, the receiving vessel 300 can be set as a diversion structure, that is, to receive the material after smelting and guide it to the next processing station. In this embodiment, the receiving vessel 300 is set as an independent holding device, so the receiving vessel 300 needs to be set to be movable along the first horizontal direction to replace the receiving vessel 300 to meet the use requirements. In addition, the loading device 200 needs to be close to the furnace body 31 to complete the loading operation, but when the distance between it and the furnace body 31 is close, it may affect the rotation and smelting of the furnace body 31. Therefore, in this embodiment, the loading device 200 is also set to be movable along the first horizontal direction to meet the structural and functional requirements.

[0044] Further, the feeding device 200 includes a feeding guide groove extending in the first horizontal direction, and the feeding end of the feeding guide groove is located on one side of the base 1 in the first horizontal direction, and the discharging end of the feeding guide groove is arranged corresponding to the furnace body 31. The feeding device 200 can be arranged in various forms, and can be adapted according to the material form, site restrictions, etc. In this embodiment, the feeding device 200 is arranged as the feeding guide groove, so that the material can be loaded on the side of the furnace body 31, away from the high temperature area, extending the service life of the equipment and having a higher safety factor.

[0045] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention.
