Description

Technical Field

[0001] This utility model relates to the field of smelting furnace technology, and in particular to a smelting furnace for smelting metal scrap. Background Technology

[0002] In modern industrial production, the effective recycling and reuse of metal waste is of great significance for resource conservation and environmental protection. As a key piece of equipment for achieving this goal, the performance of metal waste smelting furnaces directly affects the efficiency and quality of metal recycling.

[0003] In actual operation, uneven heating inside the smelting furnace is a prominent issue. Due to factors such as heat transfer methods and furnace structure, there are significant temperature differences between the upper and lower layers of the furnace. The upper layer has relatively insufficient heat, resulting in a slow melting rate of the metal scrap and prolonging the entire smelting cycle. While the lower layer can reach higher temperatures, overheating may cause excessive oxidation of the metal and other adverse chemical reactions. In addition, the upper molten slurry is prone to contact with oxygen in the air, resulting in an oxidation reaction. This not only forms a layer of oxide impurities on the surface of the molten slurry, reducing the purity of the metal, but also increases metal loss, affecting the quality and yield of the final product. Utility Model Content

[0004] In order to overcome the problems of existing metal scrap smelting furnaces, which suffer from uneven heating between the upper and lower layers and easy oxidation of the upper molten slurry, resulting in slow metal smelting speed and a large number of oxide impurities, this utility model provides a metal scrap smelting furnace.

[0005] The technical solution is as follows: A smelting furnace for smelting metal scrap includes a rotary smelting furnace assembly, a combustion base assembly, and a flue gas filter tower; the combustion base assembly is located at the lower end of the rotary smelting furnace assembly; a flue gas filter tower is located on one side of the rotary smelting furnace assembly; the rotary smelting furnace assembly includes a smelting furnace; a base is located below the smelting furnace; roller track support frames are located at both the front and rear ends below the smelting furnace, four roller track support frames are provided, and the bearing frames of the roller track support frames are fixedly connected to the base; a material transport vehicle is located at the center of the upper end of the base; gas burners are located on both sides of the material transport vehicle, and the gas burners are fixedly connected to the base.

[0006] Furthermore, the flue gas filtration tower is equipped with multiple layers of flue gas filter elements inside.

[0007] Furthermore, a servo drive motor is provided at one end of the roller track support frame, and the output end of the servo drive motor is connected to the roller drive of the roller track support frame.

[0008] Furthermore, the output end of the smelting furnace is connected to the output gas channel of the flue gas filter tower.

[0009] Furthermore, a protective gas blowing pipe is installed inside one end of the smelting furnace, and the protective gas blowing pipe is fixedly connected to the input end of the flue gas filter tower.

[0010] Furthermore, a high-temperature resistant discharge valve is provided on the lower end face of the smelting furnace, and the high-temperature resistant discharge valve is connected to the interior of the smelting furnace.

[0011] Furthermore, the high-temperature resistant discharge valve is integrally molded with the smelting furnace.

[0012] The beneficial effects are as follows: In the metal smelting process, the smelting furnace provides stable power output through a servo drive motor, which drives the rollers of the roller track support frame to rotate. The rotation of the roller track support frame directly drives the smelting furnace above it to rotate synchronously. The molten metal inside the smelting furnace can continuously roll under the action of rotation, thereby achieving an accelerated stirring effect. This continuous rolling stirring allows the upper and lower layers of the molten metal to mix continuously, effectively preventing the upper layer of the molten metal from being colder than the lower layer due to faster heat dissipation. This fundamentally solves the problem of uneven heating, greatly improves the melting efficiency, and ensures that the molten metal can undergo a melting reaction in a uniform temperature environment. At the same time, the gas burners on both sides below the smelting furnace continuously operate, providing a stable heat source for the smelting furnace through the large amount of heat generated by combustion. This continuous combustion heating method can... It effectively blocks the influence of the external environment on the internal temperature of the smelting furnace, preventing the internal temperature of the smelting furnace from decreasing, thus providing suitable and stable temperature conditions for the smelting of molten metal, further improving the overall smelting speed, and allowing the metal to reach the required state for smelting more quickly. The protective gas blowpipe continuously and evenly blows protective gas into the smelting furnace. After entering, these protective gases form a dense gas protective layer on the surface of the molten metal, thus isolating the air from contacting the surface of the molten metal, thereby preventing the surface of the molten metal from reacting with oxygen in the air at high temperatures and causing oxidation. This process not only improves the purity of the smelted metal and reduces oxides produced by oxidation, but also effectively reduces the interference of oxides on the composition of the molten metal, thereby ensuring the stability of the composition of the smelted metal and ensuring that the final smelted metal can meet the strict requirements of subsequent processing for composition.

[0013] By installing a flue gas filter tower, the flue gas filter tower is used to filter the flue gas inside the smelting furnace, thereby effectively reducing the pollution of metal smelting flue gas to the environment. Attached Figure Description

Detailed Implementation

[0020] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0021] Example 1

[0022] like Figures 1-5 As shown, a smelting furnace for smelting metal scrap includes a rotary smelting furnace assembly 1, a combustion base assembly 2, and a flue gas filter tower 3. The combustion base assembly 2 is located at the lower end of the rotary smelting furnace assembly 1. The flue gas filter tower 3 is located on one side of the rotary smelting furnace assembly 1. The rotary smelting furnace assembly 1 includes a smelting furnace 101. A base 201 is located below the smelting furnace 101. Roller track support frames 204 are provided at both the front and rear ends of the lower part of the smelting furnace 101. Four roller track support frames 204 are provided, and the bearing frames of the roller track support frames 204 are fixedly connected to the base 201. A material transport vehicle 202 is located at the center of the upper end of the base 201. Gas burners 203 are provided on both sides of the material transport vehicle 202, and the gas burners 203 are fixedly connected to the base 201.

[0023] The flue gas filter tower 3 is equipped with multiple layers of flue gas filter elements.

[0024] A servo drive motor 205 is provided at one end of the roller track support frame 204, and the output end of the servo drive motor 205 is connected to the roller drive of the roller track support frame 204.

[0025] The output end of the smelting furnace 101 is connected to the gas channel at the output end of the flue gas filter tower 3.

[0026] A protective gas blow-off pipe 102 is installed inside one end of the smelting furnace 101, and the protective gas blow-off pipe 102 is fixedly connected to the input end of the flue gas filter tower 3.

[0027] During the metal smelting process, the smelting furnace 101 provides stable power output through the servo drive motor 205, which drives the rollers of the roller track support frame 204 to rotate. The rotation of the roller track support frame 204 directly drives the smelting furnace 101 above it to rotate synchronously. The molten metal inside the smelting furnace 101 can continuously roll under the action of rotation, thereby achieving the effect of accelerated stirring. This continuous rolling stirring allows the upper and lower layers of the molten metal to be constantly mixed, thus effectively preventing the upper layer of the molten metal from being colder than the lower layer due to faster heat dissipation. This fundamentally solves the problem of uneven heating, greatly improves the melting efficiency, and ensures that the molten metal can undergo a melting reaction in a uniform temperature environment. At the same time, the gas burners 203 on both sides below the smelting furnace 101 continuously operate, providing a stable heat source for the smelting furnace 101 through the large amount of heat generated by combustion. This continuous combustion heating method... This design effectively blocks the influence of the external environment on the internal temperature of the smelting furnace 101, preventing the internal temperature of the smelting furnace 101 from decreasing. This provides suitable and stable temperature conditions for the smelting of the molten metal, further improving the overall smelting speed and allowing the metal to reach the required state for smelting more quickly. The protective gas blowpipe 102 continuously and evenly blows protective gas into the smelting furnace 101. After entering, these protective gases form a dense gas protective layer on the surface of the molten metal, thus isolating the air from contacting the surface of the molten metal. This prevents the surface of the molten metal from reacting with oxygen in the air at high temperatures and causing oxidation. This process not only improves the purity of the smelted metal and reduces oxides produced by oxidation, but also effectively reduces the interference of oxides on the composition of the molten metal, thereby ensuring the stability of the composition of the smelted metal and ensuring that the final smelted metal meets the strict requirements for composition in subsequent processing.

[0028] Example 2

[0029] Based on Example 1, such as Figures 1-5 As shown, a high-temperature resistant discharge valve 103 is provided on the lower end face of the smelting furnace 101, and the high-temperature resistant discharge valve 103 is connected to the interior of the smelting furnace 101.

[0030] The high-temperature resistant discharge valve 103 is integrally formed with the smelting furnace 101.

[0031] By setting up the flue gas filter tower 3, the flue gas filter tower 3 is used to filter the flue gas inside the smelting furnace 101, thereby effectively reducing the pollution of the environment by the metal smelting flue gas. The high temperature resistant discharge valve 103 is used to directly discharge the molten metal inside the smelting furnace 101 into the material transport vehicle 202, which facilitates the discharge and transfer of materials.
