Description

Technical Field

[0001] This utility model relates to the field of ceramsite production and processing technology, specifically a multi-stage cooling device for shale ceramsite. Background Technology

[0002] The cooling process also has a significant impact on the quality of expanded clay aggregate. Generally, a reasonable cooling regime for expanded clay aggregate is considered to be as follows: after the calcined expanded clay aggregate passes through the highest temperature, it should be rapidly cooled to 700℃. When the expanded clay aggregate cools from 700℃ to 400℃, it is best to allow it to cool slowly. This is because rapid cooling causes strong thermal shrinkage stress inside and on the surface of the expanded clay aggregate, resulting in a network of micro-cracks on its surface and reducing the particle strength. However, rapid cooling can be carried out below 400℃. Currently, there is no dedicated cooling and molding device for expanded clay aggregate. Workers need to transfer the expanded clay aggregate multiple times to meet the above cooling requirements, which is a cumbersome and inefficient process. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a multi-stage cooling device for shale ceramsite, which solves the problems of cumbersome procedures and low efficiency in the current ceramsite processing and cooling process.

[0004] This utility model discloses a multi-stage cooling device for shale ceramsite, comprising an electric conveyor and a material basket. A primary cooling structure and a secondary cooling structure are fixedly connected to both sides of the upper surface of the electric conveyor. The primary cooling structure includes a processing box with door openings on both sides. An exhaust structure is provided on the upper surface of the processing box. The secondary cooling device includes a top plate, with support columns fixedly connected to the four corners of the lower surface of the top plate. The bottom ends of the support columns are fixedly connected to the upper surface of the electric conveyor. Inclined plates are fixedly connected to both the front and back of the top plate. Cooling structures are fixedly connected to the upper surfaces of both the top plate and the inclined plates.

[0005] As a further improvement of this utility model, a box door is rotatably connected inside the doorway, and a gap is left between the edge of the box door and the inner wall of the doorway.

[0006] As a further improvement of this utility model, ear plates are fixedly connected to the front and back sides of the inner wall of the door opening near the top, and rotating shafts are fixedly connected to the front and back sides of the box door near the top, with the rotating shafts rotatably connected inside the ear plates.

[0007] As a further improvement of this utility model, the exhaust structure includes a first chassis, an exhaust fan is installed at the bottom of the inner wall of the first chassis, and an exhaust hole is provided on the upper surface of the processing box at a position corresponding to the first chassis.

[0008] As a further improvement of this utility model, the cooling structure includes a second chassis, and a cooling fan is installed on the top of the inner wall of the second chassis.

[0009] As a further improvement of this utility model, both the surface of the top plate and the surface of the inclined plate are provided with through grooves, and the position of the cooling structure corresponds to the position of the through grooves.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model utilizes an electric conveyor to automatically move the material basket after it is placed on the conveyor belt. The material basket is then automatically moved by the electric conveyor, allowing it to sequentially enter the first and second cooling structures. This eliminates the need for manual transfer of shale ceramsite. The first cooling structure on the electric conveyor allows the shale ceramsite to be slowly cooled from 700°C to 400°C. The second cooling structure allows for rapid cooling of the shale ceramsite below 400°C, meeting the cooling requirements of shale ceramsite, significantly simplifying the workflow and improving work efficiency.

[0014] 2. This utility model, through door openings on both sides of the processing box and the door connected to the box by lugs inside the door openings, along with a push rod on one side of the processing box, allows the box door to be automatically pushed open when the material basket moves in and out of the processing box, and the box door to be automatically closed after the material basket enters the processing box, which plays a certain role in heat preservation and prevents the temperature inside the processing box from dropping too quickly. Through the first chassis and exhaust fan set on the top of the processing box, along with the exhaust holes opened on the upper surface of the processing box, the exhaust fan can carry the heat in the processing box to the outside after it is turned on, so that the shale ceramsite can be slowly cooled. Through the cooling fans set on the top plate and the inclined plate, the shale ceramsite in the material basket can be cooled by air from multiple angles, so that the shale ceramsite can be cooled quickly.

[0025] Please see Figure 1-4This utility model discloses a multi-stage cooling device for shale ceramsite, comprising an electric conveyor 1 and a material basket 2. Ventilation holes are provided around the material basket 2. A push rod 3 is fixedly connected to one side of the material basket 2. A primary cooling structure and a secondary cooling structure are fixedly connected to both sides of the upper surface of the electric conveyor 1, respectively. The primary cooling structure includes a processing box 4. A temperature display 401 is fixedly connected to the front of the processing box 4 to display the real-time temperature inside the processing box 4. Door openings 5 ​​are provided on both sides of the processing box 4. An exhaust structure is provided on the upper surface of the processing box 4. The secondary cooling device includes a top plate 12. Support columns 13 are fixedly connected to the four corners of the lower surface of the top plate 12. The bottom ends of the support columns 13 are fixedly connected to the upper surface of the electric conveyor 1. Inclined plates 14 are fixedly connected to the front and back of the top plate 12. Cooling structures are fixedly connected to the upper surfaces of the top plate 12 and the inclined plates 14.

[0026] A box door 7 is rotatably connected inside the doorway 5. There is a gap between the edge of the box door 7 and the inner wall of the doorway 5. Ear plates 6 are fixedly connected to the front and back of the inner wall of the doorway 5 near the top. A pivot 8 is fixedly connected to the front and back of the box door 7 near the top. The pivot 8 is rotatably connected to the inside of the ear plates 6.

[0027] By rotating the box door 7 connected at the doorway 5, the material basket 2 will automatically push the box door 7 open and enter as the electric conveyor 1 moves toward the processing box 4. When the material basket 2 enters the middle position of the processing box 4, the box door 7 will automatically reset and block the doorway 5 without manual intervention.

[0028] In this embodiment, the exhaust structure includes a first housing 10, an exhaust fan 11 is installed at the bottom of the inner wall of the first housing 10, and an exhaust hole 9 is provided on the upper surface of the processing box 4 at a position corresponding to the first housing 10.

[0029] It should be noted that when the exhaust fan 11 is working, it blows air upwards to remove heat from the processing box 4, and does not directly direct the airflow towards the shale ceramsite in the material basket 2, thereby achieving the purpose of slow cooling.

[0030] In this embodiment, the cooling structure includes a second chassis 16, a cooling fan 17 is installed on the top of the inner wall of the second chassis 16, and through slots 15 are opened on the surface of the top plate 12 and the surface of the inclined plate 14. The position of the cooling structure corresponds to the position of the through slots 15.

[0031] Once the temperature of the shale ceramsite drops below 400℃, the electric conveyor 1 brings the material basket 2 directly below the top plate 12. At this time, the cooling fan 17 on the top plate 12 and the cooling fan 17 on the inclined plate 14 simultaneously cool the shale particles in the material basket 2. By cooling from multiple angles, the temperature of the shale ceramsite can be quickly reduced, achieving the purpose of rapid cooling.

[0032] In summary, when using this device to cool shale ceramsite, the shale ceramsite is first loaded into the material basket 2, and then the electric conveyor 1 is started to move the material basket 2 towards the primary cooling structure. During this process, the push rod 3 on the material basket 2 will push open the box door 7 in the doorway 5 and enter the processing box 4. After that, the box door 7 will automatically close, and at the same time, the exhaust fan 11 will be started to remove the heat from the processing box 4. The cooling speed can be adjusted by controlling the power of the exhaust fan 11, and the operator can observe the temperature in the processing box 4 through the temperature display 401.

[0033] Once the temperature drops below 400℃, the electric conveyor 1 is restarted to send the material basket 2 to the secondary cooling structure. The cooling fan 17 is then turned on, and the cooling fan 17 cools the shale ceramsite in the material basket 2 from multiple angles, allowing it to cool down quickly.

[0034] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
