In addition, the direct overflow of high-temperature gas will cause the heat in the gas to not be effectively utilized, and the energy utilization efficiency is not very good.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0028] To further illustrate each embodiment, the present invention provides drawings, which are part of the disclosure of the present invention and are mainly used to illustrate the embodiments. They can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, ordinary technicians in the field should be able to understand other possible implementation methods and advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0029] According to an embodiment of the utility model, an environmentally friendly and energy-saving aluminum melting furnace is provided.

[0030] The present invention is now further described in conjunction with the accompanying drawings and specific implementation methods. Figure 1-4 As shown, an environmentally friendly and energy-saving aluminum melting furnace according to an embodiment of the utility model includes a base 1 and a melting furnace body 2, the melting furnace body 2 is fixedly installed at the top position of the base 1, a bracket 9 is arranged at the middle position on the top of the melting furnace body 2, a motor 10 is fixedly installed at the middle position on the top of the bracket 9, one end of the motor 10 passes through one side of the bracket 9 and is connected to a drive shaft 11, a sealing disk 12 is fixedly installed at the bottom position of the drive shaft 11, and the sealing disk 12 is fitted with the melting furnace body 2, a plurality of groups of raw material barrels 4 are installed around the top surface of the sealing disk 12, a plurality of groups of adjusting grooves 5 are opened inside the raw material barrel 4, a sealing plate 6 is slidingly and sealingly connected inside the adjusting groove 5, a fixed plate 8 is welded at the top position of the surface of one side of the raw material barrel 4, a sealing cover 7 is rotatably connected to the top of the fixed plate 8, and the sealing cover 7 is fitted with the top of the raw material barrel 4.

[0031] In one embodiment, a sealing groove 14 is provided on one side of the top of the smelting furnace body 2 .

[0032] In one embodiment, a receiving groove 15 is provided at the bottom of the raw material barrel 4 , a spring 16 is fixedly installed at the top of the receiving groove 15 , and a sealing ring 17 is installed at the bottom of the spring 16 .

[0033] In one embodiment, a furnace chamber 3 is opened on one side of the interior of the smelting furnace body 2, directly below the sealing groove 14, and a heater 13 is installed at the bottom of the furnace chamber 3. The heater 13 and the furnace chamber 3 are basic components of the smelting furnace, so they are not described in detail.

[0034] In one embodiment, the sealing ring 17 is a raised structure, which is provided to match the slope and groove of the sealing groove 14 to ensure the coordination between the structures.

[0035] In one embodiment, the bottom of the sealing cover 7, the outside of the sealing plate 6 and the bottom of the sealing disk 12 are all wrapped with sealing gaskets. The sealing gaskets are made of high-temperature resistant rubber material to ensure the sealing of the connection.

[0036] In one embodiment, the height of the bracket 9 is higher than that of the raw material barrel 4 . The height is set to prevent the rotation of the raw material barrel 4 from being blocked by the bracket 9 , thereby ensuring that the raw material barrel 4 can be adjusted smoothly.

[0037] In one embodiment, the size of the sealing groove 14 is the same as that of the sealing ring 17, and a slope is provided inside the sealing groove 14. The size is set to ensure that the sealing ring 17 can move smoothly into the sealing groove 14 to achieve sealing operation, avoid the hot air inside the furnace chamber 3 from leaking through the gap, reduce heat loss, and prevent burns to personnel. Then the slope is set to facilitate the subsequent removal of the raw material barrel 4 from the sealing groove 14 when the sealing disk 12 rotates. When the sealing disk 12 rotates, the sealing ring 17 will also move synchronously. At this time, the sealing ring 17 will be affected by the slope inside the sealing groove 14 and will move along the slope, thereby compressing the internal spring 16 so that the sealing ring 17 can be retracted into the accommodating groove 15. At this time, the raw material barrel 4 can be removed from the sealing groove 14. When other raw material barrels 4 are subsequently moved to the sealing groove 14 position, the sealing ring 17 can be re-inserted into it by the ejection of the spring 16 to achieve sealing operation.

[0038] Working principle: In actual use, personnel can add the materials to be processed into the raw material barrel 4, and then the operation of the motor 10 can drive the sealing plate 12 to rotate as a whole, so that the raw material barrel 4 loaded with the raw materials can be moved to the position of the sealing groove 14. At this time, the sealing ring 17 at the bottom of the raw material barrel 4 can be popped out and inserted into the sealing groove 14 to achieve a sealed connection between the two. Then, personnel can pull and insert the sealing plate 6 in turn, so that the raw materials can be gradually dropped inside the raw material barrel 4. At the same time, it can avoid the direct fall of the raw materials, which causes the raw material barrel 4 to directly contact the furnace chamber 3, and prevent The high-temperature gas inside the furnace chamber 3 directly overflows and causes burns to personnel, thereby improving the safety of the operation. At the same time, the step-by-step closing operation allows the heat discharged from the furnace chamber 3 to be retained in the raw material tube 4, so that this part of the heat can be used to preheat the raw materials that will be used later, thereby achieving effective utilization of heat, reducing overall consumption, and reducing the energy required for subsequent heating of the raw materials, achieving the purpose of energy saving and environmental protection. After the raw materials are added to the furnace chamber 3, they can be smelted through the heater 13, which is convenient for subsequent processing. The device as a whole has the advantages of high operational safety, utilization of added heat, and prevention of heat dissipation.
