Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0016] Please see Figure 1-4 This utility model provides a technical solution: This utility model proposes an energy-saving device for ceramic kilns, including a feeding hopper 1, a rotary kiln 10, and a discharge section 18. The top of the feeding hopper 1 has an inlet 2, and the bottom of the inlet 2 is connected to an auxiliary preheating section 8 on one side of the feeding hopper 1. The rotary kiln 10 is installed on one side of the auxiliary preheating section 8, and the discharge section 18 is installed at the end of the rotary kiln 10. One side of the discharge section 18 is fixedly installed on a fixing plate 19, and a fan 20 is installed on the other side of the fixing plate 19. A heat recovery pipe 4 is installed on each side of the fan 20. The auxiliary preheating section 8 and the rotary kiln 10 are rotatably connected by a first bearing 9, and the discharge section 18 and the rotary kiln 10 are rotatably connected by a second bearing 17.
[0017] In practical applications, the rotary kiln 10 is started, and the material is fed into the rotary kiln 10 through the feed port 2 on the feeding bin 1 for calcination.
[0018] It should also be noted that a support rod 5 is installed between the fixing plate 19 at the top of the two heat recovery pipes 4 and the feeding bin 1. A support sleeve 7 is fitted on the heat recovery pipe 4 at the bottom of each support rod 5. The support sleeve 7 and the support rod 5 on the same side are fixedly connected by a connecting shaft 6.
[0019] Please see Figure 1 When calcination is carried out and heat energy is recovered and utilized through the heat recovery pipe 4, the heat recovery pipe 4 is supported by the support rod 5 and the support sleeve 7 sleeved on the outside of the heat recovery pipe 4, so that the structure is more stable.
[0020] It should also be noted that heat recovery preheating ports 3 are provided on both sides of the auxiliary preheating section 8 at the ends of the two heat recovery pipes 4, and each heat recovery preheating port 3 is equipped with a stainless steel dustproof net 24. Please see Figure 3 When the material at the auxiliary preheating section 8 is preheated, it facilitates the output of hot air from the heat recovery pipe 4, while preventing impurities from entering the rotary kiln 10 and affecting the quality of the calcined product.
[0021] It should also be noted that a first limiting ring 11 is installed on the outer side of the rotary kiln 10 near the auxiliary preheating section 8, a second limiting ring 12 is installed in the middle of the rotary kiln 10, and a third limiting ring 13 is installed on the outer side of the rotary kiln 10 near the blower 20. A toothed ring 15 is installed between the third limiting ring 13 and the discharge section 18. The first limiting ring 11, the second limiting ring 12, the third limiting ring 13, and the toothed ring 15 are all fixedly installed on the rotary kiln 10. The bottom of the toothed ring 15... A servo motor 16 is installed in the part, and a gear 14 is fixedly installed at the output end of the servo motor 16. The gear 14 meshes with the tooth groove on the outer side of the gear ring 15. The bottom of the first limiting ring 11 is engaged with the first limiting groove 21, the bottom of the second limiting ring 12 is engaged with the second limiting groove 22, and the bottom of the third limiting ring 13 is engaged with the third limiting groove 23. The first limiting ring 11, the second limiting ring 12, and the third limiting ring 13 are respectively located in the transition zone, the firing zone, and the cooling zone inside the rotary kiln 10. Please see Figure 1 , 2 When the kiln body rotates, the servo motor 16 drives the gear 14 to rotate the gear ring 15, so that the rotary kiln 10 can rotate at a constant speed through the first bearing 9 and the second bearing 17. The first limiting ring 11, the second limiting ring 12 and the third limiting ring 13 are respectively engaged in the first limiting groove 21, the second limiting groove 22 and the third limiting groove 23 to ensure the stability of the kiln body in the transition zone, the firing zone and the cooling zone. It should also be noted that a discharge port 25 is provided on one side of the bottom of the discharge section 18, and the discharge port 25 is set at a 25° angle. Please see Figure 4 During the discharge process, the sintered material automatically slides out through the 25° inclined discharge port 25 at the bottom of the discharge section 18. The inclined design reduces material residue and improves discharge efficiency.
[0022] Please see Figures 1 to 4 The rotary kiln 10 is started, and the material is fed into the rotary kiln 10 through the feed port 2 on the feeding hopper 1 for calcination. At the same time, the blower 20 is started to draw the hot airflow from the cooling section at the end of the rotary kiln 10 to the heat recovery pipes 4 on both sides. While achieving rapid cooling, the hot airflow is guided through the end of the heat recovery pipe 4 to the heat recovery preheating port 3 on the auxiliary preheating section 8 to assist in preheating the newly fed material, thereby improving calcination efficiency, recovering waste heat, and saving energy.
