Description

Technical Field

[0001] This utility model relates to the field of metal furnace technology, specifically to an additive dispensing device for metal furnaces. Background Technology

[0002] A metal furnace is a device used to heat metal to a molten state, typically used in metal casting, smelting, and alloy manufacturing processes. It heats the metal above its melting point, transforming it from a solid to a liquid state, facilitating subsequent casting, forming, or chemical processing. Furnaces are widely used in the processing of metals such as steel, non-ferrous metals, and cast iron.

[0003] A metal smelting additive dispensing device (announcement number: CN221192258U) disclosed in the public notice includes a receiving plate and a dispensing box. The upper surface of the receiving plate is equipped with a metering mechanism, which includes a sliding block, a composite spring, an elastic column, a connecting block, and a connecting plate. The bottom of the sliding block is slidably connected to the inner wall of the receiving plate. This metal smelting additive dispensing device dispenses the additive into the feed pipe. After the amount of additive is determined by the scale markings on the outer surface of the feed pipe, the connecting block can be pulled. This causes the connecting plate, which is fixedly mounted on the left side of the connecting block, and the baffle, which is mounted on the left side of the connecting plate, to move away from the inside of the feed pipe. After the baffle moves away from the inside of the feed pipe, the problem of controlling the amount of additive dispensed is effectively solved, achieving convenient dispensing. Furthermore, it allows for dispensing according to actual needs, improving its practical application.

[0004] The aforementioned patent achieves the effect of controlling the amount of material fed through the cooperation of components such as composite springs, elastic columns, and connecting blocks. However, it cannot achieve the effect of automatically dispensing additives. Therefore, we propose an additive dispensing device for metal furnaces. Utility Model Content

[0005] To overcome the above-mentioned defects, this utility model provides an additive dispensing device for metal furnaces, which solves the technical problem that existing technologies cannot better achieve automated additive dispensing.

[0006] According to one aspect, at least one embodiment of the present invention provides an additive dispensing device for a metal furnace, comprising: a furnace, a controller fixedly connected to the side of the furnace, a display panel provided on the side of the controller, control buttons provided on the side of the controller, and an automatic feeding device provided on the side of the furnace. The automatic feeding device includes a housing, one end of which is fixedly connected to the side of the furnace. A motor is fixedly connected to the inner side of the housing, and a spiral extrusion rod is fixedly connected to the output shaft of the motor. A feed inlet is located at the top of the housing, and a connecting pipe is fixedly connected to the top of the feed inlet. A material hopper is fixedly connected to the top of the connecting pipe. An opening is located on the side of the furnace. This automatic feeding device uses a motor-driven spiral extrusion rod to feed material from the material hopper into the furnace, offering advantages such as increased automation, efficiency, precise control, and ease of operation.

[0007] For example, in at least one embodiment of this utility model, an additive dispensing device for a metal furnace further includes: the side of the opening is located on the displacement trajectory of the spiral extruder, and there is a gap between the circumferential surface of the spiral extruder and the inner side of the outer shell. The design of the gap and the opening can optimize the material conveying process, reduce equipment wear, prevent blockages, and improve the stability and efficiency of the overall system.

[0008] The diameter of the connecting pipe is the same as the diameter of the feed inlet, which is located directly above the screw extruder. This design effectively ensures smooth material transport and uniform feeding, while reducing waste and the risk of blockage, thereby improving the efficiency and reliability of the equipment.

[0009] A sieve is fixedly connected to the inner side of the connecting pipe, and a glass observation plate is provided on the side of the material hopper. The design of the sieve and the glass observation plate optimizes material filtration, flow observation, and equipment monitoring, improving system efficiency, equipment reliability, and ensuring operational safety.

[0010] The diameter of the opening is larger than the diameter of the spiral extruder, and the outer shell is located in the upper middle part of the furnace. The design of the larger opening diameter and the upper middle position of the outer shell optimizes the smoothness of material feeding, the uniformity of furnace temperature, and the protection and efficiency of the equipment, thereby improving the stability and economy of the overall production process.

[0011] According to another aspect, at least one embodiment of this utility model also provides an additive dispensing device for a metal furnace, comprising: an anti-clogging device provided on the circumferential surface of the spiral extruder, the anti-clogging device including a rotating sleeve, the inner side of the rotating sleeve being fixedly connected to the circumferential surface of the spiral extruder, a connecting rod being fixedly connected to the circumferential surface of the rotating sleeve, one end of the connecting rod being rotatably connected to a rotating shaft, and a rubber rod being fixedly connected to the circumferential surface of the rotating shaft. This anti-clogging device continuously cleans materials, reduces the risk of clogging, reduces equipment wear, and improves production efficiency, ensuring the stable operation of the spiral extruder system and enhancing the reliability and efficiency of the equipment.

[0012] For example, in at least one embodiment of this utility model, an additive dispensing device for a metal furnace further includes: the bottom of the sieve is located on the displacement trajectory of the rubber rod, and there is a gap between the circumferential surface of the rotating shaft and the inner surface of the connecting pipe. This design, through the cleaning action of the rubber rod, prevents clogging of the sieve, reduces friction and wear, ensures a smooth material screening process, extends the service life of the equipment, and improves overall production efficiency.

[0013] There is a gap between the circumferential surface of the rotating shaft and the inner surface of the housing, and a return torsion spring is fixedly connected to the circumferential surface of the rotating shaft. The design of the gap and the use of the return torsion spring not only help reduce friction and improve the flexibility and stability of the rotating shaft, but also help reduce vibration and noise, ensure the self-recovery capability of the system, and ultimately improve the reliability and service life of the equipment.

[0014] One end of the reset torsion spring is fixedly connected to the side of the connecting rod, and the initial state of the reset torsion spring is a relaxed state. Through its relaxed initial state, the reset torsion spring provides a flexible restoring force, which helps the system maintain a stable state, reduce external interference, achieve self-adjustment, and provide buffering and precise positioning functions, ultimately improving the reliability, lifespan, and operating efficiency of the equipment.

[0015] There is a gap between the circumferential surface of the rotating sleeve and the inner surface of the outer shell, and the width of the rotating sleeve is smaller than the width of the feed inlet. The gap between the rotating sleeve and the outer shell, and the design that the width of the rotating sleeve is smaller than the width of the feed inlet, mainly serve to reduce friction, improve rotational flexibility, prevent jamming, accommodate thermal expansion, optimize material flowability, and at the same time ensure the stability and sealing of the system, ultimately ensuring that the equipment can operate efficiently and smoothly.

[0016] The beneficial effects of the embodiments of this utility model are as follows: 1. In this utility model, the motor, screw extruder, feed inlet, and connecting pipe work together to achieve the following: When the motor is started, it drives the screw extruder to rotate. The additive inside the feed hopper falls into the connecting pipe, passes through a screen, and enters the outer shell through the feed inlet. The rotation of the screw extruder pushes the additive inside the outer shell to the opening, where it falls into the furnace to promote metal melting and achieve a catalytic reaction. This results in improved automation, efficiency, precise control, and ease of operation.

[0017] 2. In this utility model, the motor, rotating sleeve, rubber rod, and rotating shaft work together to achieve the following: When the motor is started, it drives the spiral extruder to rotate. The rotation of the spiral extruder drives the rotating sleeve to rotate, which in turn drives the connecting rod to rotate. The rotating rod then drives the rotating shaft to rotate, which in turn drives the rubber rod to rotate, thus striking the bottom of the screen. This achieves continuous material cleaning, reduces the risk of clogging, lowers equipment wear, improves production efficiency, ensures the stable operation of the spiral extruder system, enhances equipment reliability and efficiency, prevents screen clogging, reduces friction and wear, and ensures a smooth material screening process.

[0022] To keep the drawings concise, only the parts relevant to the utility model are shown schematically in each drawing; these do not represent the actual structure of the product.

[0026] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0027] like Figures 1-5 As shown, it illustrates an additive dispensing device for a metal furnace according to an embodiment of the present invention, including a furnace 1, a controller 2 fixedly connected to the side of the furnace 1, a display panel 3 provided on the side of the controller 2, a control button 4 provided on the side of the controller 2, and an automatic feeding device 5 provided on the side of the furnace 1. The automatic feeding device 5 includes a housing 51, one end of which is fixedly connected to the side of the furnace 1. A motor 52 is fixedly connected to the inner side of the housing 51, and a spiral extrusion rod 53 is fixedly connected to the output shaft of the motor 52. A feed inlet 54 is provided on the top of the housing 51, and a connecting pipe 55 is fixedly connected to the top of the feed inlet 54. A material box 56 is fixedly connected to the top of the connecting pipe 55. An opening 57 is provided on the side of the furnace 1. This automatic feeding device 5 uses the motor 52 to drive the spiral extrusion rod 53 to feed material from the material box 56 into the furnace 1, and has multiple functions such as improving automation, efficiency, precise control, and ease of operation.

[0028] In some examples, the side of the opening 57 lies on the displacement trajectory of the spiral extruder 53, and there is a gap between the circumferential surface of the spiral extruder 53 and the inner surface of the housing 51. The design of the gap and the opening 57 can optimize the material conveying process, reduce equipment wear, prevent blockages, and improve the stability and efficiency of the overall system.

[0029] The diameter of the connecting pipe 55 is the same as the diameter of the feed inlet 54, which is located directly above the screw extruder 53. This design effectively ensures smooth material transport and uniform feeding, and reduces the risk of waste and blockage, thereby improving the efficiency and reliability of the equipment.

[0030] A screen 58 is fixedly connected to the inner side of the connecting pipe 55, and a glass observation plate 59 is provided on the side of the material box 56. The design of the screen 58 and the glass observation plate 59 optimizes the filtration, flow observation and equipment monitoring of materials, improves the system's working efficiency, equipment reliability and ensures operational safety.

[0031] The diameter of the opening 57 is larger than the diameter of the spiral extruder 53, and the outer shell 51 is located in the upper middle part of the furnace 1. The design of the larger diameter of the opening 57 and the upper middle position of the outer shell 51 optimizes the smoothness of material feeding, the uniformity of temperature in the furnace 1, and the protection and efficiency of the equipment, thereby improving the stability and economy of the overall production process.

[0032] For example, such as Figures 1-5 As shown, the motor 52 is started, driving the spiral extruder 53 to rotate. The rotation of the spiral extruder 53 causes the additives inside the feed hopper 56 to gradually fall into the connecting pipe 55. Passing through the screen 58, these additives smoothly enter the outer shell 51 from the feed port 54 and are pushed to the opening 57 of the outer shell 51 by the rotation of the spiral extruder 53. Finally, the additives fall into the furnace 1 from the opening 57, accelerating the metal melting process through their unique catalytic effect, thereby promoting the chemical reaction and physical changes of the metal in the furnace 1, achieving the expected catalytic reaction effect, and ensuring the efficiency and quality of metal melting.

[0033] like Figures 1-5 As shown, this invention illustrates an additive dispensing device for a metal furnace in another embodiment. The device includes an anti-clogging device 6 on the circumferential surface of a spiral extruder 53. The anti-clogging device 6 comprises a rotating sleeve 61, the inner side of which is fixedly connected to the circumferential surface of the spiral extruder 53. A connecting rod 62 is fixedly connected to the circumferential surface of the rotating sleeve 61, and one end of the connecting rod 62 is rotatably connected to a rotating shaft 63. A rubber rod 64 is fixedly connected to the circumferential surface of the rotating shaft 63. This anti-clogging device 6 continuously cleans materials, reduces the risk of clogging, lowers equipment wear, and improves production efficiency, ensuring the stable operation of the spiral extruder 53 system and enhancing the reliability and efficiency of the equipment. In some examples, the bottom of the screen 58 is located on the displacement trajectory of the rubber rod 64, and there is a gap between the circumferential surface of the rotating shaft 63 and the inner surface of the connecting pipe 55. This design, through the cleaning action of the rubber rod 64, prevents the screen 58 from clogging, reduces friction and wear, ensures a smooth material screening process, extends the service life of the equipment, and improves overall production efficiency.

[0034] There is a gap between the circumferential surface of the rotating shaft 63 and the inner surface of the housing 51, and a return torsion spring 65 is fixedly connected to the circumferential surface of the rotating shaft 63. The design of the gap and the use of the return torsion spring 65 not only help to reduce friction and improve the flexibility and stability of the rotating shaft 63, but also help to reduce vibration and noise, ensure the self-recovery capability of the system, and ultimately improve the reliability and service life of the equipment.

[0035] One end of the reset torsion spring 65 is fixedly connected to the side of the connecting rod 62, and the initial state of the reset torsion spring 65 is a relaxed state. Through its relaxed initial state, the reset torsion spring 65 provides a flexible restoring force, which can help the system maintain a stable state, reduce external interference, achieve self-adjustment, and provide buffering and precise positioning functions, ultimately improving the reliability, lifespan and operating efficiency of the equipment.

[0036] There is a gap between the circumferential surface of the rotating sleeve 61 and the inner surface of the outer shell 51, and the width of the rotating sleeve 61 is smaller than the width of the feed inlet 54. The gap between the rotating sleeve 61 and the outer shell 51, and the design that the width of the rotating sleeve 61 is smaller than the width of the feed inlet 54, are mainly used to reduce friction, improve rotational flexibility, prevent jamming, accommodate thermal expansion, optimize material flow, and at the same time ensure the stability and sealing of the system, ultimately ensuring that the equipment can operate efficiently and smoothly.

[0037] For example, such as Figures 1-5As shown, the motor 52 is started, which drives the spiral extrusion rod 53 to rotate. The rotation of the spiral extrusion rod 53 drives the rotating sleeve 61 to rotate, which in turn drives the connecting rod 62 to rotate. The rotation of the connecting rod 62 drives the rotating shaft 63 to rotate, which in turn drives the rubber rod 64 to rotate. The rotation of the rubber rod 64 strikes the bottom of the screen 58. When the rubber rod 64 encounters resistance, it folds through the rotating shaft 63. When the rubber rod 64 loses resistance, the rotating shaft 63 rotates back to its original position through the reset torque of the reset torsion spring 65. The reset of the rotating shaft 63 then resets the rubber rod 64.

[0038] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
