Abstract
Description
Technical Field
[0001] This utility model relates to the field of smelting furnace technology, and in particular to a smelting furnace with an automatic feeding system. Background Technology
[0002] A smelting furnace is an important piece of equipment in industrial production used to transform metals or other materials from a solid state to a liquid state. It is widely used in steel, non-ferrous metal smelting, casting, and other fields. In early industrial production, the charging process of smelting furnaces mainly relied on manual operation.
[0003] This method has many drawbacks. The handling and addition of metal materials relies entirely on manual labor. Workers must first move the heavy metal materials from the storage area to the smelting furnace. Because the materials are usually quite heavy, this process is extremely physically demanding. Moreover, the amount of material moved each time is limited, requiring workers to make multiple trips between the storage area and the smelting furnace to pour the material into the furnace one by one. This makes the feeding speed very slow. With the advancement of large-scale industrial production, the demand for metal products has increased dramatically, and the drawbacks of the traditional manual feeding method have become increasingly apparent. The large amount of manpower required means high production costs, and with limited manpower, it seriously affects production efficiency. In addition, the furnace temperature is extremely high when the smelting furnace is operating, and there are certain safety risks associated with manually approaching the furnace to add materials. To address these problems, the existing technology urgently needs improvement. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a smelting furnace with an automatic feeding system.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a smelting furnace with an automatic feeding system, including a support frame, and further comprising:
[0006] The furnace body of the smelting furnace is provided with a furnace body discharge port;
[0007] A tilting system includes a first electric cylinder, which is fixed on the support frame. A transverse frame is fixedly connected to the piston rod end of the first electric cylinder. The transverse frame is laterally slidably disposed on the support frame. A transverse shaft is symmetrically rotatably connected to the transverse frame. The ends of the two transverse shafts are fixedly connected to the surface of the furnace body. A drive motor is fixedly installed at the bottom of the transverse frame. A worm gear is connected to the output end of the drive motor. A worm wheel that meshes with the worm gear is fixedly connected to the surface of the transverse shaft near the worm gear.
[0008] An automatic feeding system is installed on top of the support frame and is used to feed material into the feed inlet at the top of the smelting furnace body.
[0009] Furthermore, the automatic feeding system includes a collection bin and a second electric cylinder. The collection bin is fixedly installed above the support frame. A material guide channel is fixedly connected to the lower part of the collection bin. A feeding hopper is fixedly connected to the outlet end of the material guide channel. The outlet end of the feeding hopper corresponds to the feed inlet at the top of the smelting furnace. The second electric cylinder is hinged to the side wall of the collection bin. A baffle plate is hinged to the telescopic end of the second electric cylinder. The baffle plate is rotatably connected to the collection bin to block or open the outlet at the lower part of the collection bin. A vibration motor is installed on the side wall of the material guide channel.
[0010] Furthermore, the transverse frame is a frame structure, and the ends of the two transverse axes are rotatably connected to both sides of the inner wall of the transverse frame.
[0011] Furthermore, the support frame is equipped with guide rails for guiding the transverse frame to slide laterally.
[0012] Furthermore, the silo has a funnel-shaped structure that is wider at the top and narrower at the bottom.
[0013] Furthermore, the material guide channel has an inclined trough-shaped structure.
[0014] Furthermore, the rotation point of the baffle is located above the lower outlet of the collection bin.
[0015] Furthermore, both the first electric cylinder and the second electric cylinder are linear electric push rods.
[0016] Compared with the prior art, the present invention has the following beneficial effects:
[0017] By incorporating an automatic feeding system and a tilting system, this invention effectively solves the technical problems of low efficiency, high labor intensity, and the impact of high temperatures during furnace tilting on the feeding system in existing technologies. Specifically, the automatic feeding system enables automatic material addition, eliminating the need for manual handling and tilting, significantly improving feeding efficiency and reducing labor intensity and costs. The first electric cylinder in the tilting system drives a transverse movement frame, causing the furnace body to move laterally and offset from the automatic feeding system. This prevents the high temperatures generated during smelting from directly affecting the automatic feeding system, protecting it from heat damage and improving system safety and reliability. Simultaneously, the drive motor, through a worm gear and worm wheel, drives the furnace body to rotate and tilt, achieving automatic pouring of molten liquid and further enhancing the level of automation. Therefore, this invention integrates automatic feeding, furnace body transverse movement for obstacle avoidance, and automatic tilting, significantly improving the operating efficiency, automation level, and safety of the smelting furnace, and possesses significant practical value.

[0023] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.
[0024] Smelting furnace technology plays a crucial role in industrial production, used to convert solid materials into liquids, and is widely used in metal smelting, casting, and other fields. Traditional smelting furnaces typically rely on manual labor for feeding, requiring workers to carry heavy materials to the furnace side and add them in batches. This method is not only labor-intensive and inefficient, making it difficult to meet the demands of modern large-scale production, but also poses significant safety hazards when manually feeding materials under the high-temperature operating conditions of the smelting furnace. To address these limitations of existing technologies, this invention proposes a smelting furnace with an automatic feeding system.
[0025] like Figures 1 to 4 The smelting furnace shown includes a support frame 1, and further includes:
[0026] The furnace body 2 of the smelting furnace is provided with a furnace body discharge port 21;
[0027] The tilting system includes a first electric cylinder 402, which is fixed on the support frame 1. The piston rod end of the first electric cylinder 402 is fixedly connected to a transverse frame 401. The transverse frame 401 is laterally slidably mounted on the support frame 1. A transverse shaft 3 is symmetrically rotatably connected to the transverse frame 401. The ends of the two transverse shafts 3 are fixedly connected to the surface of the furnace body 2 of the smelting furnace. A drive motor 403 is fixedly installed at the bottom of the transverse frame 401. A worm gear 404 is connected to the output end of the drive motor 403. A worm wheel 405 that meshes with the worm gear 404 is fixedly connected to the surface of the transverse shaft 3 near the worm gear 404.
[0028] Automatic feeding system 5 is installed on top of support frame 1 and is used to feed material into the feed port at the top of furnace body 2 of smelting furnace.
[0029] The automatic feeding system 5 includes a collection bin 501 and a second electric cylinder 504. The collection bin 501 is fixedly installed above the support frame 1. The lower part of the collection bin 501 is fixedly connected to a guide channel 502. The outlet end of the guide channel 502 is fixedly connected to a feeding hopper 503. The outlet end of the feeding hopper 503 corresponds to the feed inlet at the top of the furnace body 2. The second electric cylinder 504 is hinged to the side wall of the collection bin 501. The telescopic end of the second electric cylinder 504 is hinged to a baffle plate 505. The baffle plate 505 is rotatably connected to the collection bin 501 to block or open the outlet at the lower part of the collection bin 501. A vibration motor 6 is installed on the side wall of the guide channel 502.
[0030] During operation, the metal material to be melted is first conveyed to the collection bin 501 of the automatic feeding system 5 via an external conveying device. The outlet end of the feeding hopper 503 is always aligned with the feed inlet at the top of the furnace body 2. When material needs to be fed into the furnace body 2, the second electric cylinder 504, hinged to the side wall of the collection bin 501, is activated. The telescopic end of the second electric cylinder 504 retracts, causing the baffle plate 505 hinged to it to rotate upwards around the rotational connection point with the collection bin 501, no longer blocking the outlet at the bottom of the collection bin 501. At this time, the material in the collection bin 501 slides downwards along the guide channel 502 under its own gravity. Simultaneously, the vibrating motor 6 installed on the side wall of the material guide channel 502 is activated. The vibration generated by the vibrating motor 6 accelerates the sliding speed of the material within the material guide channel 502 until the material passes through the material guide channel 502 and enters the feeding hopper 503. Finally, the material enters the furnace body 2 through the feeding hopper 503, thus realizing the automatic addition of metal material into the furnace body 2. When it is no longer necessary to add material, the second electric cylinder 504 is activated, extending its telescopic end and causing the baffle plate 505 to flip downward, re-sealing the outlet of the collection bin 501 and stopping the material feeding, thereby controlling the amount of material added.
[0031] Before or after smelting operations in the furnace body 2, if a tilting operation is required, or to prevent the high temperatures during smelting from affecting the automatic feeding system 5, the tilting system can be activated. Activating the first electric cylinder 402 in the tilting system extends its telescopic end, pushing the transverse frame 401, which is fixedly connected to it, to slide laterally on the support frame 1. The movement of the transverse frame 401, via two transverse shafts 3, causes the furnace body 2 to move laterally until it is offset from the feeding hopper 503. In this way, during smelting, the feed inlet at the top of the furnace body 2 is no longer directly facing the feeding hopper 503, preventing direct radiation or convection of high temperatures to the feeding hopper 503 and the automatic feeding system 5, thus protecting the components of the feeding system. When it is necessary to pour out the molten liquid from the furnace body 2, the drive motor 403 on the side wall of the transverse frame 401 is activated. The drive motor 403 drives the worm 404 to rotate. The worm 404 meshes with the worm wheel 405 fixed on the surface of the horizontal shaft 3, driving the worm wheel 405 to rotate. This in turn drives the horizontal shaft 3 to rotate the furnace body 2 around the horizontal shaft 3, causing a tilting action. This causes the furnace body outlet 21 of the furnace body 2 to move downward, pouring out the molten liquid inside the furnace body 2.
[0032] As one embodiment of this utility model, the transverse frame 401 is a frame structure, and the ends of the two transverse shafts 3 are respectively rotatably connected to the inner walls of the transverse frame 401 frame.
[0033] As one embodiment of this utility model, the support frame 1 is provided with a guide rail for guiding the transverse sliding frame 401 to slide laterally.
[0034] As one embodiment of this utility model, the material collection bin 501 has a funnel-shaped structure that is larger at the top and smaller at the bottom.
[0035] During operation, the function of the material collection bin 501 is further optimized by defining it as a funnel-shaped structure that is wider at the top and narrower at the bottom. The funnel-shaped bin 501 can more effectively guide the stored material to the lower guide channel 502, reducing the possibility of material forming "dead zones" or "bridging" within the bin, thereby improving the smoothness and reliability of material descent. This optimization is crucial for ensuring the stable operation of the automatic feeding system, especially when handling materials with poor flowability, significantly reducing the risk of blockage and ensuring a continuous and stable supply of material to the smelting furnace body 2.
[0036] As one embodiment of this utility model, the material guide channel 502 has an inclined groove-shaped structure.
[0037] During operation, the material conveying process is further optimized by defining the guide channel 502 as an inclined trough structure. The inclined trough structure can fully utilize gravity as the main driving force for material falling, reducing friction and resistance within the channel and improving the efficiency and reliability of material conveying. Compared with horizontal or non-trough channels, this structural design can guide material flow more effectively, reducing the possibility of material accumulation or blockage within the channel. Especially when used in conjunction with the funnel-shaped collection bin above, it can form a smooth material conveying path, ensuring that material can enter the feeding hopper stably and continuously.
[0038] In one embodiment of this utility model, the rotation point of the baffle plate 505 is located above the lower outlet of the collection bin 501.
[0039] Specifically, "the rotation point is set above the lower outlet of the collection bin" means that the shaft or hinge connecting the baffle plate 505 to the collection bin 501 and allowing it to rotate is located above the bottom outlet of the collection bin 501. This arrangement determines the rotation trajectory of the baffle plate 505. When the second electric cylinder 504 drives the baffle plate 505 to rotate upward, the baffle plate 505 flips upward, and its lower edge moves upward, thus fully opening the lower outlet of the collection bin 501, allowing the material to flow out smoothly. When the second electric cylinder 504 drives the baffle plate 505 to rotate downward, the baffle plate 505 covers the lower outlet of the collection bin 501 downward, blocking it and preventing the material from flowing out. Setting the rotation point above the outlet ensures that the baffle plate 505 will not obstruct the falling material when open, and can tightly fit the edge of the outlet when closed, achieving a reliable seal.
[0040] In one embodiment of this utility model, both the first electric cylinder 402 and the second electric cylinder 504 are linear electric push rods.
[0041] Working principle of this utility model:
[0042] In operation, the metal material to be melted is conveyed to the collection bin 501 of the automatic feeding system 5 via an external conveyor belt. The outlet end of the feeding hopper 503 corresponds to the feed inlet at the top of the furnace body 2. When material needs to be fed into the furnace body 2, the second electric cylinder 504, hinged to the side wall of the collection bin 501, is activated. The telescopic end of the second electric cylinder 504 retracts, causing the baffle plate 505 to rotate along the rotation point rotatably connected to the collection bin 501, thereby causing the lower part of the baffle plate 505 to flip upwards and no longer affect the collection bin. The outlet at the bottom of the hopper 501 is blocked. The material in the hopper 501 slides down the guide channel 502 under its own gravity. At the same time, the vibration motor 6 installed on the side wall of the guide channel 502 is started. The vibration of the vibration motor 6 accelerates the downward sliding of the material in the guide channel 502 until the material enters the feeding hopper 503 through the guide channel 502. Finally, the material enters the furnace body 2 through the feeding hopper 503, realizing the automatic addition of metal materials into the furnace body 2 and improving the efficiency of material addition.
[0043] When it is not necessary to add material into the furnace body 2 of the smelting furnace, the second electric cylinder 504 is activated. The telescopic end of the second electric cylinder 504 extends and drives the second electric cylinder 504 to rotate and block the outlet of the collection bin 501, so that the material in the collection bin 501 no longer enters the material guide channel 502, thereby stopping the addition of material into the furnace body 2 of the smelting furnace and thus controlling the amount of material added.
[0044] The first electric cylinder 402 of the tilting system is activated. The first electric cylinder 402 is fixedly connected to the support frame 1. The extension end of the first electric cylinder 402 pushes the transverse frame 401 to slide laterally on the support frame 1. The movement of the transverse frame 401, via two transverse shafts 3, moves the furnace body 2 until it is offset from the feeding hopper 503 by a certain distance. This ensures that the high temperature during melting will not affect the feeding hopper 503 through the feed inlet at the top of the furnace body 2, and will not interfere with subsequent operations of the furnace body 2. The furnace body 2 is tilted and then started to melt the incoming metal material. When it is necessary to pour out the molten liquid in the furnace body 2, the drive motor 403 on the side wall of the transverse frame 401 is started. The drive motor 403 drives the worm 404 to rotate. The worm 404 drives the worm wheel 405 fixed on the surface of the transverse shaft 3 to rotate. The worm wheel 405 drives the transverse shaft 3 to rotate the furnace body 2 and produce a tilting action, so that the furnace body outlet 21 of the furnace body 2 moves downward to pour out the molten liquid in the furnace body 2.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope. All such changes and modifications fall within the scope of protection claimed by this utility model, which is defined by the appended claims and their equivalents.
