[0002] High-calorific-value fly ash typically contains a higher amount of unburned carbon and other combustibles, which is the main reason for its higher calorific value. Generally, ordinary fly ash contains less than 10% carbon, while high-calorific-value fly ash may contain more than 15% carbon, or even higher.

[0003] A large-scale fly ash storage device, with publication number CN214932600U, includes a silo body for facilitating fly ash storage. A feed pipe is fixedly connected to the top of any side wall of the silo body. This invention utilizes a heating plate at the top of the silo body and an embedded insulation layer in the side wall to maintain a stable temperature within the silo body, thereby preventing excessive humidity that could cause fly ash agglomeration and hinder subsequent recycling.

[0004] Regarding the aforementioned technologies, the existing storage devices have the following drawbacks: the accumulation of a large amount of high-calorific-value fly ash makes it difficult for internal heat to dissipate, which can easily create a high-temperature environment that can lead to spontaneous combustion.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] Example 1: Reference Figure 1-6The high-calorific-value fly ash storage device for cement clinker shown includes a frame 1, which serves as the main structure of the entire storage device, accommodating and supporting internal components and providing space for fly ash storage. Multiple placement plates 7 are arranged inside the frame 1 to hold the fly ash. The multiple placement plates 7 increase the storage area and improve storage capacity. Each placement plate 7 has an outer groove 10 to facilitate air circulation, allowing air to be more evenly distributed around the placement plates 7, thus facilitating ventilation of the fly ash. Multiple ventilation holes 9 are also provided on the outer side of the placement plates 7, communicating with the ventilation holes 10. These ventilation holes 9 allow air to pass through the placement plates 7 and into the fly ash placed on them, achieving ventilation of the fly ash. To reduce the possibility of spontaneous combustion, a load-bearing pipe 8 is provided on the outer side of the placement plate 7. The load-bearing pipe 8 is fixedly connected to the inner wall of the frame 1. The load-bearing pipe 8 supports the placement plate 7 and ensures the stability of the placement plate 7 when bearing fly ash. Multiple connecting holes 14 are provided at the bottom of the placement plate 7 and the top of the load-bearing pipe 8. The position and number of the connecting holes 14 of the placement plate 7 and the connecting holes 14 of the load-bearing pipe 8 correspond. The connecting holes 14 allow air passing through the load-bearing pipe 8 to enter the placement plate 7, thereby achieving ventilation of the fly ash on the placement plate 7. A ventilation assembly is provided on the outer side of the frame 1. The ventilation assembly includes multiple centrifugal fans 5 fixedly connected to the outer side of the frame 1. The function of the centrifugal fans 5 is to generate airflow, provide power for the entire ventilation assembly, and enable air to flow within the device. The output ends of the multiple centrifugal fans 5 are fixedly connected to input pipes 6, which are used to deliver the airflow generated by the centrifugal fans 5 to subsequent components. A connecting pipe 3 is provided on the outside of the frame 1. The input pipe 6 is connected to the connecting pipe 3. The connecting pipe 3 serves to collect and distribute the airflow delivered by the multiple input pipes 6. Multiple interconnected air supply pipes 4 are fixedly connected to the outside of the connecting pipe 3. The multiple air supply pipes 4 pass through the frame 1 and introduce the airflow in the connecting pipe 3 into the interior of the frame 1. The air supply pipes 4 are connected to the load-bearing pipe 8, so that the airflow generated by the centrifugal fan 5 can enter the load-bearing pipe 8 through the input pipe 6, the connecting pipe 3, and the air supply pipes 4. Finally, the airflow ventilates the fly ash on the placement plate 7 through the load-bearing pipe 8 and the connecting hole 14 on the placement plate 7, maintaining the fly ash in a good storage condition.

[0025] Example 2: Reference Figure 1-6Based on the same concept as in Embodiment 1 above, this embodiment also proposes that a guide plate 11 is fixedly connected to the outer side of the placement plate 7. The function of the guide plate 11 is to provide precise guidance for the movement of the load-bearing tube 8. A guide groove 15 adapted to the guide plate 11 is opened on the outer side of the load-bearing tube 8. The two work together to ensure that the load-bearing tube 8 slides smoothly in a specific direction, effectively avoiding deviation or shaking of the load-bearing tube 8 during movement, thereby improving the stability and accuracy of the entire device in related operations. A controller 12 is set inside the frame 1. The controller 12 is the control core of the entire device. It is responsible for receiving data from various sensors and issuing control commands to various components of the device according to a preset program to realize the automated operation and precise control of the device. A temperature and humidity sensor 13 is also set inside the frame 1. The temperature and humidity sensor 13 is used to monitor the temperature and humidity environment data inside the frame 1 in real time and transmit the data to the controller 12 so that the controller 12 can make corresponding adjustments according to environmental changes to maintain suitable temperature and humidity conditions inside the frame 1. A baffle 2 is set on the outer side of the frame 1. The baffle 2 is connected to the frame 1 by a torsion spring. The baffle 2 opens and closes automatically under the action of a torsion spring. When it is necessary to operate inside the frame 1, the baffle 2 can be pushed open. After the operation is completed, the baffle 2 automatically closes under the restoring force of the torsion spring, thus protecting the internal components of the frame 1, preventing dust and foreign objects from entering the frame 1, and protecting the internal components of the equipment from the influence of the external environment. The inner wall of the frame 1 is provided with multi-layer solid wood boards, which are made of three or more layers of thin solid wood veneers laminated together with adhesive. The multi-layer solid wood boards have good structural stability and can effectively bear the weight of the items inside the frame 1, preventing the inner wall of the frame 1 from deforming due to the load. At the same time, the solid wood material also has certain heat insulation, cushioning, and moisture-proof properties, which helps to maintain the relative stability of the temperature inside the frame 1 and to a certain extent reduce the impact of vibration and other factors on the internal items.

[0026] In this embodiment, the temperature and humidity inside the frame 1 are monitored by the temperature and humidity sensor 13. If the temperature and humidity inside the frame 1 exceed the standard, the centrifugal fan 5 is controlled by the controller 12 to introduce strong air into the load-bearing pipe 8 through the input pipe 6, connecting pipe 3, and air supply pipe 4, and into the empty groove 10 in the placement plate 7 through the connecting hole 14, and out through the ventilation hole 9. This blows air onto the bagged fly ash and ventilates the inside of the frame 1, reducing the humidity inside the frame 1 and removing heat and volatile combustible gases in time, reducing the risk of spontaneous combustion. The baffle 2 is opened, and the placement plate 7 is dragged to drive the guide plate 11 to slide out along the guide groove 15, placing the bagged fly ash in the placement plate 7 for storage.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
