[0002] The kiln tail supporting plate is located at the front end of the smoke chamber and extends into the kiln tail seal. The upper surface is built with castable for protecting the supporting plate and reducing the direct impact of the material on the supporting plate. The lower surface is exposed to the high-temperature airflow above 1000 DEG C. The main function of the supporting plate is to feed the raw material from the preheater decomposer outlet pipeline into the rotary kiln for calcination after heat exchange through the pre-decomposition system.

[0003] In the prior art, the kiln tail supporting plate is usually made of heat-resistant steel casting, such as ZG40Cr25Ni20 and the like. These materials have high heat resistance. Due to long-term exposure to high-temperature environment, the service life of the supporting plate is usually short. The kiln tail supporting plate has various forms, among which the bolt-connected supporting plate is more common. This type of supporting plate is connected to the smoke chamber baffle by bolts, and the supporting plates are also connected by bolts. However, it is troublesome to disassemble the bolts when replacing the supporting plate.

[0004] Therefore, we improve it and propose a forced air cooling kiln tail supporting plate. CONTENT OF THE UTILITY MODEL

[0028] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0029] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0030] Example

[0031] Please refer to Figure 1 ,Figure 2 , Figure 3 , Figure 4 and Figure 5 A type of air-cooled kiln tail support plate, comprising a kiln tail support plate 1, an air-cooling component 2, and a connecting component 3. The outer side of the kiln tail support plate 1 is provided with an air-cooling component 2 for reducing the internal temperature of the kiln tail support plate 1, and the lower part of the air-cooling component 2 is provided with a connecting component 3 for easy disassembly and installation.

[0032] The air-cooling assembly 2 includes a first drive motor 201 disposed on the outside of the kiln tail support plate 1. A cooling fan 202 is fixedly connected to the top of the first drive motor 201. An air inlet duct 203 is sleeved on the surface of the cooling fan 202. An adjusting cylinder 204 is rotatably connected inside the air inlet duct 203. A material blocking mesh plate 205 is fixedly connected inside the kiln tail support plate 1 through the adjusting cylinder 204. A rack plate 206 is fixedly connected to the bottom of the air inlet duct 203. A drive gear 207 is meshed with the bottom gear of the rack plate 206. A second drive motor 208 is rotatably connected to the side of the drive gear 207. A material plate 209 is fixedly connected inside the kiln tail support plate 1. Multiple rotating cylinders 210 are rotatably connected inside the material plate. When high-temperature raw material flows into the kiln tail support plate 1, the first drive motor 201 is manually started, causing the first drive motor 201 to drive the cooling fan 202 to rotate, and then the cooling fan 202 is cooled. The cold air generated by the cooling fan 202 flows into the regulating cylinder 204 through the air inlet duct 203, causing the cold air to be blown into the kiln tail support plate 1 from the regulating cylinder 204 to reduce the temperature of the raw material. At the same time, the second drive motor 208 and the third drive motor 6 are started. The second drive motor 208 drives the drive wheel to rotate, and then the drive wheel pushes the rack plate 206 through gear meshing. The rack plate 206 drives the regulating cylinder 204, the cooling fan 202 and the air inlet duct 203 to move into the kiln tail support plate 1, increasing the range of air cooling and rapidly reducing the temperature of the raw material. Meanwhile, the third drive motor 6 drives the rotating rod 5 to rotate, which in turn drives the stirring fan 4 to rotate and stir the raw material in the kiln tail support plate 1, allowing the temperature to dissipate. At the same time, when the raw material is stirred, it will drive the rotating cylinder 210 to rotate on the material plate 209, accelerating the stirring of the raw material, thereby further improving the cooling efficiency and enabling rapid reduction of the raw material temperature.

[0033] Furthermore, such as Figure 1 , Figure 3 and Figure 4As shown, the connecting assembly 3 includes a connecting plate 301 disposed at the bottom of the kiln tail support plate 1. A first connecting rod 302 is rotatably connected to one side of the connecting plate 301, and a second connecting rod 303 is rotatably connected to the other side. A first snap-fit ​​plate 304 is fixedly connected to the bottom end of the first connecting rod 302, and a first threaded hole is provided on the side of the first snap-fit ​​plate 304. A second snap-fit ​​plate 305 is fixedly connected to the bottom end of the second connecting rod 303, and a second threaded hole is provided on the side of the second snap-fit ​​plate 305. When it is necessary to install and fix the kiln tail support plate 1, the first connecting rod 302 is manually rotated. The connecting rod 302 and the second connecting rod 303 cause the first connecting rod 302 and the second connecting rod 303 to rotate the first locking plate 304 and the second locking plate 305 by an angle, thereby forming an angle between the first connecting rod 302 and the second connecting rod 303. Then, the first locking plate 304 and the second locking plate 305 are inserted into the installation position. Then, the locking rod 7 is rotated to drive the locking plate, so that the locking plate is locked in place at the installation position by the protrusion 9. When it is necessary to remove the kiln tail support plate 1, the above operation can be reversed. The fixed kiln tail support plate 1 can be quickly installed and removed, which is convenient to use.

[0034] The usage process of the air-cooled kiln tail support plate 1 provided by this utility model is as follows:

[0035] When the hot raw material flows into the kiln tail support plate 1, the first drive motor 201 is manually started, causing the first drive motor 201 to drive the cooling fan 202 to rotate. Subsequently, the cold air generated by the cooling fan 202 flows into the regulating cylinder 204 through the air inlet duct 203, causing the cold air to be blown into the kiln tail support plate 1 from the regulating cylinder 204 to reduce the temperature of the raw material. At the same time, the second drive motor 208 and the third drive motor 6 are started, causing the second drive motor 208 to drive the drive wheel to rotate. Then, the drive wheel pushes the rack plate 206 through gear meshing, causing the rack plate 206 to move the regulating cylinder 204, the cooling fan 202, and the air inlet duct 203 into the kiln tail support plate 1, increasing the air cooling range and rapidly reducing the temperature of the raw material. Meanwhile, the third drive motor 6 drives the rotating rod 5 to rotate, causing the rotating rod 5 to drive the stirring fan 4 to rotate and stir the kiln tail support plate. The raw material in plate 1 allows for heat dissipation. Simultaneously, when the raw material is agitated, it drives the rotating drum 210 to rotate on the material plate 209, further improving cooling efficiency. This allows for rapid reduction of the raw material temperature and increased cooling efficiency. When it is necessary to install and fix the kiln tail support plate 1, manually rotate the first connecting rod 302 and the second connecting rod 303, causing them to respectively rotate the first locking plate 304 and the second locking plate 305 by an angle. An angle is then formed between the first connecting rod 302 and the second connecting rod 303. The first locking plate 304 and the second locking plate 305 are then inserted into the installation position. Then, rotating the locking rod 7 drives the locking plate, causing it to be locked in place by the protrusion 9. When it is necessary to disassemble the kiln tail support plate 1, the above operation is reversed.
