[0022] Please see the appendix Figure 1 - Appendix Figure 5An embodiment of the present invention provides a multi-component composite melting device for low-smoke halogen-free flame-retardant cable materials, comprising a melting tank 1, a large washer 11 fitted onto the melting tank 1, a small washer 26 fitted onto the large washer 11, a cover plate 8 fixedly connected to the small washer 26, a motor 7 fixedly connected to the cover plate 8, a stirring shaft 22 snapped onto one end of the motor 7, a stirring blade 21 fixedly connected to the outer wall of the stirring shaft 22, a bottom plate 18 fixedly connected to one end of the stirring shaft 22, a first partition 16 and a second partition 17 fixedly connected inside the melting tank 1, a reaction chamber 15 provided on the first partition 16, a melting chamber 19 provided between the first partition 16 and the second partition 17, a cooling chamber 20 provided below the second partition 17, a secondary air inlet pipe 4, a feed pipe 5 and a main air inlet pipe 6 fixedly connected to the cover plate 8, and a first mounting hole 9 provided on the cover plate 8. The secondary air inlet pipe 4, the feed pipe 5, and the main air inlet pipe 6 are connected to a reaction chamber 15 at one end. The melting tank 1 is provided with an inner cavity 31, and a heating pipe 23 is fixedly connected to the inner cavity 31. A heating core 24 is provided inside the heating pipe 23. The outer wall of the melting tank 1 is fixedly connected with a discharge pipe 13 and a cooling pipe 14. A sixth mounting hole 30 is opened on the discharge pipe 13, and a fifth mounting hole 29 is opened on the cooling pipe 14. One end of the discharge pipe 13 is connected to a cooling chamber 20, and one end of the cooling pipe 14 is connected to the inner cavity 31. The outer wall of the melting tank 1 is fixedly connected with a main exhaust pipe 3 and a secondary exhaust pipe 10. A third mounting hole 27 is opened on the main exhaust pipe 3, and a second mounting hole 25 is opened on the secondary exhaust pipe 10. The outer wall of the melting tank 1 is fixedly connected with a bracket 12 and a mounting base 2. A fourth mounting hole 28 is opened on the mounting base 2.
[0023] Working principle: When using this invention, the device is first fixed through the mounting base 2 and the fourth mounting hole 28. The bracket 12 can enhance the stability of the melting tank 1. Then, multi-component materials are added through the feed pipe 5. The main air inlet pipe 6 and the secondary air inlet pipe 4 introduce the gas required for production. After starting the motor 7, it will drive the stirring shaft 22 to rotate. The stirring blades 21 on the stirring shaft 22 can fully mix the materials in the reaction chamber 15. At the same time, the heating tube 23 and the heating core 24 in the inner cavity 31 of the melting tank 1 will generate heat, providing a suitable temperature for the reaction chamber 15 and the melting chamber 19 to ensure the reaction and melting effect. After the material completes the reaction in the reaction chamber 15, it enters the melting chamber 19. The material is further melted in the melting chamber 19 and then enters the cooling chamber 20. The cooling pipe 14 introduces a cooling medium into the inner cavity 31 to help cool the material in the cooling chamber 20. The waste gas generated during the process is discharged from the main exhaust pipe 3 and the secondary exhaust pipe 10. The cooled material is finally output from the discharge pipe 13. The cover plate 8 seals the melting tank 1 with the large gasket 11 and the small gasket 26 to reduce heat loss and impurity entry. The first mounting hole 9, the second mounting hole 25, the third mounting hole 27, the fifth mounting hole 29, and the sixth mounting hole 30 facilitate the installation and connection of various components. The bottom plate 18 can prevent the material from accumulating at the bottom of the stirring shaft 22 to ensure smooth stirring and conveying.
