It provides reliable technical guarantee for the high-temperature processing of various materials. This roasting kiln is often equipped with a cooling system.

[0003] The traditional rotary kiln cooling device usually consists of a rotating cylinder similar to the roasting cylinder, which is designed to rotate and is similar to the main roasting cylinder but usually shorter. This cylinder can be rotated by an axis drive system, and a cooling medium, usually air or gas, is injected into the cooling device. These cooling media are fed into the cylinder by various means, such as through nozzles or pipes, and the cooled material is discharged from the discharge end of the cooling cylinder. Usually, the design of the cylinder or auxiliary devices can ensure that the material is discharged smoothly and enters the next processing stage or transportation link.

[0004] However, the cooling nozzles in the traditional rotary roasting kiln cooling device often adopt an integrated fixed structure. This cooling nozzle has a limited range when cooling the inside of the cooling cylinder and cannot fully cool the inner wall of the cooling cylinder, thereby reducing the cooling effect of this cooling device.

[0007] Furthermore, the discharge assembly includes a discharge bin, and the discharge bin is fixedly connected to the bottom of the cooling cylinder.

[0008] Furthermore, a bin cover is slidably connected inside the discharge bin, and a fixing frame is fixedly connected to a side wall of the discharge bin.

[0009] Furthermore, a cylinder is fixedly connected inside the fixing frame, and a push plate is fixedly connected to an output end of the cylinder.

[0010] Furthermore, two ends of the push plate are fixedly connected with connecting plates, and a plurality of pulleys are rotatably connected inside the connecting plates.

[0011] Furthermore, the pulley is slidably connected inside the fixing frame.

[0012] Furthermore, a plurality of turntables are fixedly connected to the side wall of the bin cover.

[0013] Furthermore, both ends of the side walls of the connection plate are rotatably connected with rotating plates, and one end of each rotating plate is rotatably connected to the inside of the turntable.

[0014] The utility model has the following beneficial effects:

[0015] 1.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Reference Figure 1-Figure 2, the utility model provides an embodiment: a rotary roasting kiln cooling device, including a cooling cylinder 1, the cooling cylinder 1 is fixedly connected with a base 2, the top of the base 2 is fixedly connected with a rotating frame 3, the top of the base 2 is fixedly connected with a motor 4, the output end of the motor 4 is fixedly connected with a cam 5, the cam 5 is rotatably connected to the inside of the rotating frame 3, the top of the base 2 is fixedly connected with a fixed column 6, the fixed column 6 is slidably connected with a sliding column 2 7, the fixed column 6 is fixedly connected with a fixed shaft 8, the fixed column 6 is rotatably connected with a nozzle 11, a double-track slide groove 9 is opened on one side of the outer wall of the nozzle 11, the fixed shaft 8 is slidably connected to the inside of the double-track slide groove 9, a spring 10 is arranged between the sliding column 2 7 and the nozzle 11, and a discharge assembly is arranged at the bottom of the cooling cylinder 1, and the discharge assembly is used to discharge materials.

[0024] Specifically, the motor 4 is started, and the motor 4 drives the cam 5 in the rotating frame 3 to rotate through the cam 5. The rotation of the cam 5 pushes the sliding column 2 7 to slide in the fixed column 6. The movement of the sliding column 2 7 is transmitted to the nozzle 11, so that the tail of the nozzle 11 moves periodically in the fixed column 6. At the same time, the fixed shaft 8 constrains the double-track slide groove 9, so that the nozzle 11 can rotate inside the fixed column 6. This mechanism design effectively expands the coverage of the nozzle 11 on the inner wall of the cooling cylinder 1, ensuring uniform cooling of the entire surface. The setting of the spring 10 ensures that the sliding column 2 7 can be quickly and stably reset, so that after the spraying cycle ends, the nozzle 11 can quickly return to the starting position to prepare for the next round of spraying. This structure and mechanism effectively guarantees the performance of the cooling device, and can quickly and effectively cool high-temperature materials to a safe handling temperature, thereby significantly reducing the risks and safety hazards of the materials in subsequent processing and transportation.

[0025] Reference Figure 3 The discharge assembly includes a discharge bin 12, which is fixedly connected to the bottom of the cooling cylinder 1, and a bin cover 13 is slidably connected inside the discharge bin 12. A fixed frame 14 is fixedly connected to the side wall of the discharge bin 12, and a cylinder 15 is fixedly connected inside the fixed frame 14. A push plate 16 is fixedly connected to the output end of the cylinder 15, and connecting plates 17 are fixedly connected at both ends of the push plate 16. A plurality of pulleys 20 are rotatably connected inside the connecting plate 17, and the pulley 20 is slidably connected inside the fixed frame 14. A plurality of turntables 19 are fixedly connected to the side wall of the bin cover 13, and rotating plates 18 are rotatably connected to both ends of the side wall of the connecting plate 17, and one end of each rotating plate 18 is rotatably connected to the inside of the turntable 19.

[0026] Specifically, the function of the cylinder 15 is to pull the push plate 16 to make it displace vertically, and the connecting plates 17 on both sides of the push plate 16 are pulled accordingly. A plurality of pulleys 20 are installed inside the connecting plate 17. The pulleys 20 enable the connecting plate 17 to slide smoothly inside the fixed frame 14. The sliding of the connecting plate 17 drives the rotating plate 18 on its side wall to displace and rotate on the bearing installed inside the turntable 19. The inclination angle of the rotating plate 18 will change with its rotation on the turntable 19. Through the connection between the turntable 19 and the bin cover 13, the rotating plate 18 can pull the bin cover 13 to slide out of the discharge bin 12. Such a structural design ensures that the cooled material can be smoothly unloaded from the discharge end of the cooling cylinder 1, and the material is smoothly discharged from the discharge bin 12 to enter the next processing stage or transportation link. This discharge mechanism effectively improves the automation and efficiency of the production line and ensures the continuous flow and processing of materials during the production process.

[0027] Working principle: When the cooling cylinder 1 needs to be sprayed with the nozzle 11, the motor 4 is started first. The motor 4 outputs a rotating force to the cam 5, driving the cam 5 to rotate inside the rotating frame 3. The rotation of the cam 5 can periodically push the slide column 2 7, so that the slide column 2 7 slides inside the fixed column 6. The tail of the nozzle 11 can be pushed by the sliding of the slide column 2 7. At this time, the nozzle 11 is constrained by the fixed shaft 8 on the double-line slide groove 9 to make the nozzle 11 rotate periodically inside the fixed column 6. At this time, the spray range of the nozzle 11 on the inner wall of the cooling cylinder 1 can be increased. At the same time, the setting of the spring 10 can ensure that the slide column 2 7 is quickly reset. This structure ensures the cooling effect of this cooling device, effectively cools the high-temperature material quickly, and reduces the material in subsequent processing and Risks and safety hazards during transportation. When the cooled material needs to be discharged, the cylinder 15 is started, and the cylinder 15 pulls the push plate 16 to make the push plate 16 move vertically. At this time, the connecting plates 17 on both sides of the push plate 16 are pulled, and the connecting plates 17 slide inside the fixed frame 14 through the multiple pulleys 20 inside the connecting plates 17. The sliding of the connecting plates 17 drives the rotating plates 18 on the side walls to move and rotate inside the turntable 19. The inclination angle of the rotating plate 18 changes accordingly, and the connection between the turntable 19 and the bin cover 13 pulls the bin cover 13 to make it slide out from the inside of the discharge bin 12. With this structure, the cooled material can be unloaded from the discharge end of the cooling cylinder 1, ensuring that the material is discharged smoothly and enters the next processing stage or transportation link.

[0028] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
