Description

Technical Field

[0001] This utility model relates to the field of heat treatment equipment technology, and specifically discloses a dual heat treatment mechanism for waste non-ferrous metals. Background Technology

[0002] In a narrow sense, non-ferrous metals, also known as non-ferrous metals, are a general term for all metals other than iron, manganese, and chromium. In a broader sense, non-ferrous metals also include non-ferrous alloys. Non-ferrous alloys are alloys composed of one or more other elements as the base metal (usually more than 50%). Heat treatment refers to a metal heat treatment process in which the chemical composition and structure of a metal material are changed on its surface or inside by means of heating, holding, and cooling in a solid state, so as to obtain the desired properties.

[0003] Chinese patent CN218620993U discloses a dual heat treatment mechanism for waste non-ferrous metals, including a housing. A first motor is fixedly connected to the top of the housing, and a rotating column is fixedly connected to the output end of the first motor. The rotating column, located away from the output end of the first motor, extends into the inner cavity of the housing and is movably connected to the bottom of the inner cavity of the housing via a bearing. A shelf is fixedly connected to the surface of the rotating column, and an electric heating plate is fixedly connected to the left side of the inner cavity of the housing. This invention, through the coordinated use of the housing, first motor, rotating column, shelf, electric heating plate, hot air blower, telescopic pipe, air outlet hood, drive box, second motor, turntable, pin shaft, movable frame, shell, spring, limiting plate, and connecting rod, solves the problem that existing dual heat treatment mechanisms for waste non-ferrous metals cannot quickly and evenly heat the workpiece during use, resulting in low processing efficiency, increased processing costs, and thus being unsuitable for practical use.

[0004] The aforementioned document discloses a dual heat treatment mechanism for waste non-ferrous metals. In use, the workpiece is heated by the reciprocating motion of the fan hood. However, the reciprocating motion of the fan hood causes uneven heating of the workpiece on both sides. Therefore, a dual heat treatment mechanism for waste non-ferrous metals is needed to solve this problem. Utility Model Content

[0005] This invention proposes a dual heat treatment mechanism for waste non-ferrous metals, which achieves dual heating through the synergistic action of an electric heating plate and a hot air blower, and is combined with a servo motor-driven turntable and branch pipe counter-rotating mechanism to ensure that the workpiece is heated quickly and evenly.

[0006] This utility model is implemented as follows: a dual heat treatment mechanism for waste non-ferrous metals includes a box body with a door on its outer wall. A heat treatment mechanism is located inside the box body, comprising two vertically distributed first turntables. Sleeves rotatably connected to the box body are fixedly connected to the outer walls of the two back-to-back first turntables. Multiple connecting rods are fixedly connected between the two first turntables. Multiple evenly distributed second turntables are fixedly connected to the outer walls of the multiple connecting rods. Rotating tubes are rotatably connected to the inner walls of the two sleeves. Multiple branch pipes are connected to the outer walls of the rotating tubes. Multiple evenly distributed air holes are opened at the lower ends of the outer walls of the multiple branch pipes. A hot air blower is located below the box body, and the outlet of the hot air blower is rotatably connected to the lower end of the rotating tube via a rotating joint. A driving mechanism is located on the upper surface of the box body.

[0007] In a preferred embodiment of the dual heat treatment mechanism for waste non-ferrous metals according to this utility model, the driving mechanism includes a portal frame fixedly connected to the upper end face of the housing.

The upper end of the sleeve located on the upper side extends to the top of the housing and is fixedly connected to a third bevel gear. Both the second and third bevel gears are meshed with the first bevel gear.

[0008] As a preferred embodiment of the dual heat treatment mechanism for waste non-ferrous metals of this utility model, electric heating plates are provided on both the left and right sides of the inner wall of the box.

[0012] The beneficial effects of this utility model are:

[0013] 1. By combining the electric heating plate and the hot air blower, a dual heating mode combining static radiation heating and dynamic hot air convection is achieved.

Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0022] Please see Figure 1-4A dual heat treatment mechanism for waste non-ferrous metals includes a housing 1, with a door 2 on the outer wall of the housing 1. A heat treatment mechanism is located inside the housing 1, comprising two vertically distributed first turntables 3. Sleeves 4, rotatably connected to the housing 1, are fixedly connected to the outer walls of the two back-to-back first turntables 3. Multiple connecting rods 5 are fixedly connected between the two first turntables 3. Multiple evenly distributed second turntables 6 are fixedly connected to the outer walls of the multiple connecting rods 5. Rotating pipes 8 are rotatably connected to the inner walls of the two sleeves 4. Multiple branch pipes 9 are connected to the outer walls of the rotating pipes 8. Multiple evenly distributed air holes 10 are opened at the lower ends of the outer walls of the multiple branch pipes 9. A hot air blower 11 is located below the housing 1, with its outlet rotatably connected to the lower end of the rotating pipe 8 via a rotating joint 12. A driving mechanism is located on the upper surface of the housing 1.

[0023] In this embodiment: Rotating the sleeve 4 further drives the first turntable 3 to rotate, which in turn drives multiple connecting rods 5 to rotate. The multiple connecting rods 5 further drive multiple second turntables 6 to rotate, which in turn drives the workpieces on the lower first turntable 3 and multiple second turntables 6 to rotate, so that the workpieces are heated evenly. The hot air blower 11 is started, and the hot air blower 11 blows hot air into multiple branch pipes 9 through the rotating pipe 8 and blows it out from multiple air holes 10 to assist in heating the workpieces. Rotating the rotating pipe 8 drives the multiple branch pipes 9 to rotate, so that the hot air is blown evenly onto the workpieces, so that the workpieces are heated quickly and evenly.

[0024] As a technical optimization of this utility model, the drive mechanism includes a gantry frame 13 fixedly connected to the upper end face of the housing 1. A servo motor 14 is installed on the side wall of the gantry frame 13. The output end of the servo motor 14 extends to the inner side of the gantry frame 13 and is fixedly connected to a first bevel gear 15. The upper end of the rotating tube 8 extends to the upper side of the housing 1 and is fixedly connected to a second bevel gear 16. The upper end of the upper sleeve 4 extends to the top of the housing 1 and is fixedly connected to a third bevel gear 17. The second bevel gear 16 and the third bevel gear 17 are both meshed with the first bevel gear 15.

[0025] In this embodiment: the servo motor 14 is started, and the servo motor 14 drives the first bevel gear 15 to rotate, which in turn drives the second bevel gear 16 and the third bevel gear 17 to rotate in the opposite direction. The second bevel gear 16 and the third bevel gear 17 further drive the sleeve 4 and the rotating tube 8 to rotate in the opposite direction, which in turn drives the workpiece in the turntable and the branch pipe 9 to rotate in the opposite direction, so that the hot air comes into uniform contact with the workpiece.

[0026] As a technical optimization of this utility model, electric heating plates 18 are provided on both the left and right sides of the inner wall of the box 1.

[0027] In this embodiment: two symmetrically distributed electric heating plates 18 are used to heat the internal space of the chamber 1, working in conjunction with the hot air blower 11 to ensure that the temperature of the waste non-ferrous metal is stable and uniformly distributed during the dual heat treatment process.

[0028] As a technical optimization of this utility model, multiple second turntables 6 and the upper end face of the first turntable 3 located on the lower side are all fixedly connected with limit rings 7.

[0029] In this embodiment: the limiting ring 7 is used to prevent the waste non-ferrous metal from slipping off when the turntable rotates, ensuring that the material is always within the effective heat treatment area.

[0030] As a technical optimization of this utility model, support legs are provided at the four corners of the lower end face of the box 1.

[0031] In this embodiment, the support legs are used to support the housing 1 and maintain its stability, while facilitating the installation and maintenance of the hot air blower 11 and the pipeline.

[0032] As a technical optimization of this utility model, a controller is provided on the outer wall of the door 2, and the hot air blower 11, servo motor 14 and electric heating plate 18 are all electrically connected to the controller.

[0033] In this embodiment, the controller integrates temperature, speed and other parameter adjustment functions, and the user can automatically control the heat treatment process by setting a program to achieve precise operation.

[0034] The working principle and usage process of this utility model are as follows: First, the workpiece is placed on top of multiple second turntables 6 and the lower first turntable 3. Then, the box door 2 is closed, and the electric heating plate 18 and hot air blower 11 are started. The hot air blower 11 blows hot air through the rotating pipe 8 into multiple branch pipes 9 and out through the air hole 10, acting on the workpiece. The hot air blown out by the electric heating plate 18 and hot air blower 11 provides double heating to the workpiece. Simultaneously, the servo motor 14 is started, driving the first bevel gear 15 to rotate, which in turn drives the second bevel gear 16 and the third bevel gear 17 to rotate in the opposite direction. The second bevel gear 16 and the third bevel gear 17 further drive the sleeve 4 and the rotating pipe 8 to rotate in the opposite direction. When the sleeve 4 rotates, it drives the first turntable 3 to rotate, which in turn drives multiple connecting rods 5 to rotate. The multiple connecting rods 5 further drive multiple second turntables 6 to rotate, which in turn drives the workpieces on the lower first turntable 3 and multiple second turntables 6 to rotate. When the rotating pipe 8 rotates, it drives multiple branch pipes 9 to rotate, facilitating the even blowing of hot air onto the workpiece, allowing the workpiece to be heated quickly and evenly.
