Description

Technical Field

[0001] This utility model belongs to the field of kiln head cover technology, and specifically relates to a device for preventing material accumulation in the kiln head cover. Background Technology

[0002] In industrial production processes such as cement and ceramics, the kiln hood is a key piece of equipment. Material accumulation often occurs inside due to poor material flow or changes in operating conditions. This accumulation not only reduces production efficiency and increases energy consumption but can also damage the kiln hood shell, and in severe cases, even affect the stable operation of the entire production line. Traditional methods of cleaning accumulated material rely heavily on manual labor, which is not only labor-intensive and inefficient but also makes it difficult to address the accumulation problem in a timely and effective manner. This is especially true at the steep slopes of the kiln hood, where material flow characteristics exacerbate the accumulation problem. When there is a significant amount of accumulated material, it can easily lead to material overflow, increasing the workload of employees and posing significant risks to equipment and personal safety.

[0003] To address the aforementioned issues, air cannons are commonly used as efficient cleaning tools in existing technologies. They are widely applied to cleaning accumulated material in kiln hoods. Air cannons effectively disperse and remove accumulated material and restore material flow through the impact force generated by the instantaneous release of high-pressure gas. However, using air cannons alone still presents some problems, such as incomplete cleaning, especially at the steep slopes of the kiln hood where the cleaning effect is often unsatisfactory due to space constraints and material accumulation characteristics. Another issue is untimely cleaning. Traditional methods of detecting accumulated material rely heavily on manual observation and experience-based judgment. This method is not only highly subjective but also makes it difficult to detect accumulated material problems in a timely and accurate manner, thereby increasing the risk of material overflowing at the steep slopes of the kiln hood. Utility Model Content

[0004] To address the above problems, the purpose of this utility model is to provide a device for preventing material accumulation in the kiln hood, thereby solving the problems of incomplete cleaning of material accumulation on the inner wall of the kiln hood, low automation, and untimely monitoring mentioned in the background art.

[0005] This utility model provides a device for preventing material accumulation in a kiln hood, including a kiln hood shell and an air cannon installed on the kiln hood shell for cleaning material accumulation on the inner wall of the kiln hood. It also includes a material accumulation sensor and a controller. The output end of the material accumulation sensor is connected to the signal input end of the controller to provide the controller with a signal of material accumulation on the inner wall of the kiln hood. The signal output end of the controller is used to output a control signal, which is used to control the operation of the air cannon. The number of air cannons is multiple.

[0006] Preferably, multiple air cannons are arranged alternately on the kiln head cover shell.

[0007] Preferably, the material accumulation sensor can be a sound sensor and a temperature sensor.

[0008] Preferably, there may be multiple sound sensors, and the installation locations of the multiple sound sensors include inside or outside the kiln head cover but near the opening.

[0009] Preferably, the number of temperature sensors is the same as the number of air cannons, and multiple temperature sensors are located on the kiln head cover at the positions where corresponding air cannons are installed.

[0010] Preferably, the nozzle of the air cannon includes, but is not limited to, an arc-shaped or fan-shaped nozzle.

[0011] The beneficial effects of this utility model are: by setting multiple staggered air cannons, the comprehensiveness of material cleaning can be ensured, and the probability of material collapse on the inner wall of the large slope of the kiln head hood shell can be reduced.

[0012] Based on the above, a material accumulation sensor and controller are added. The material accumulation sensor can realize intelligent monitoring of material accumulation on the inner wall of the kiln head hood. When a large amount of material accumulates, the controller controls the air cannon to operate, which improves the automation and efficiency of material cleaning. Attached Figure Description

[0018] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.

[0019] like Figure 1-4As shown, a device for preventing material accumulation in a kiln hood includes a kiln hood shell 1 and an air cannon 2 installed on the kiln hood shell 1 for cleaning material accumulation on the inner wall of the kiln hood. It also includes a material accumulation sensor 3 and a controller 4. The output of the material accumulation sensor 3 is connected to the signal input of the controller 4, providing a signal of material accumulation on the inner wall of the kiln hood. The signal output of the controller 4 outputs a control signal to control the operation of the air cannon 2. Multiple air cannons 2 are used; by arranging multiple air cannons 2 in a staggered manner, the comprehensiveness of material cleaning is ensured, reducing the probability of material collapse on the steep inner wall of the kiln hood shell 1. Furthermore, the addition of the material accumulation sensor 3 and controller 4 enables intelligent monitoring of material accumulation on the inner wall of the kiln hood. When a large amount of material accumulates, the controller 4 controls the air cannon 2 to operate, improving the automation and efficiency of material cleaning.

[0020] Furthermore, such as Figure 1-4 As shown, multiple air cannons 2 are arranged in a staggered pattern on the kiln head hood shell 1. This staggered arrangement of air cannons 2 can more effectively cover all corners of the inner wall of the kiln head hood, reducing dead zones for material accumulation and improving cleaning efficiency. Figure 2 As shown, there are five air cannons 2. Three air cannons 2 are on one side of the kiln head hood shell 1, and two air cannons 2 are on the other side of the kiln head hood shell 1. In actual application, the number of air cannons 2 can be increased or decreased according to the length and model of the kiln head hood shell 1, and the distance between two adjacent air cannons 2 can be reasonably set. The duration of the air cannons 2 should be adjusted and set according to the actual situation to ensure that the accumulated material can be effectively cleaned, while avoiding damage to the kiln head hood and equipment.

[0021] Furthermore, such as Figure 1 As shown, the material accumulation sensor 3 can be a sound sensor 5 and a temperature sensor 6. A high-sensitivity, wide-frequency response range sound sensor 5 can be selected to ensure accurate capture of the sound changes of material flow inside the kiln head hood. A sound threshold is set, which corresponds to the sound level of material flow when there is no material accumulation in the kiln head hood. When the sound signal detected by the sound sensor 5 is lower than the threshold, it is determined that there may be material accumulation on the inner wall of the kiln head hood. The temperature sensor 6 can be used to detect the temperature inside the kiln head hood shell 1. Correspondingly, a temperature threshold is preset, which corresponds to the temperature level when there is no material accumulation in the kiln head hood. When the temperature signal detected by the temperature sensor 6 is higher than the threshold, combined with the sound signal detected by the sound sensor 5 that is higher than the sound threshold, it is determined that there is material accumulation on the inner wall of the kiln head hood. The material accumulation signal is transmitted to the controller 4. The controller 4 controls the valve 8 of the air cannon 2 to open, releasing high-pressure gas to clean the material accumulation on the inner wall of the kiln head hood. The controller 4 can also be equipped with a clock module to preset the opening time of the air cannon 2 according to the actual situation. After the preset cleaning time is reached, the controller 4 controls the valve 8 of the air cannon 2 to close.

[0022] Furthermore, such as Figure 3 As shown, there can be multiple sound sensors 5. The installation positions of multiple sound sensors 5 include the inside or outside of the kiln head hood but near the opening. The sound sensors 5 can only detect local temperature changes inside the kiln head hood. By setting multiple sound sensors 5, the sound signals inside the kiln head hood can be captured more comprehensively, improving the sensitivity of material accumulation detection. At the same time, the reasonable installation position ensures that the sound sensors 5 can accurately capture the sound generated when the material accumulates.

[0023] Furthermore, such as Figure 3 As shown, the number of temperature sensors 6 is the same as the number of air cannons 2, and multiple temperature sensors 6 are respectively located on the kiln head hood shell 1 at positions corresponding to the air cannons 2. The air cannons 2 are evenly distributed on both sides of the kiln head hood shell 1. The one-to-one correspondence between the temperature sensors 6 and the air cannons 2 is as follows: Figure 3 As shown, the temperature sensor 6 is installed below the nozzle 7 of the air cannon 2, so that the cleaning area of ​​each air cannon 2 can be monitored in real time. This helps to detect and deal with the local temperature rise caused by material accumulation in a timely manner, and prevent the material accumulation from damaging the kiln head hood.

[0024] Furthermore, such as Figure 3 As shown, the nozzle 7 of the air cannon 2 includes, but is not limited to, arc-shaped or fan-shaped nozzles. The nozzle 7 of the air cannon 2 is installed on the large slope of the kiln head cover shell 1. At the same time, the slope of the kiln head cover is improved, and the angle of the upper 5 meters of the large slope is changed to 25 degrees to eliminate the possibility of material accumulation on the upper part of the large slope. The arc-shaped or fan-shaped design can expand the spray angle and coverage of the air cannon 2, so that the air cannon 2 can more effectively clean the material accumulation on the inner wall of the kiln head cover, improve the efficiency and effect of material accumulation cleaning, and also help to reduce energy consumption and noise.
