Description

Technical Field

[0001] This utility model relates to the field of preheater inner cylinder hanging plate technology, and in particular to a protective device for preheater inner cylinder hanging plates. Background Technology

[0002] The preheater inner cylinder fins are key components of the preheater. They are typically made of high-temperature resistant materials and serve to support and protect the preheater inner cylinder while promoting heat exchange between flue gas and air. These fins operate in high-temperature environments and therefore require excellent heat resistance and corrosion resistance. In cement production, the preheater inner cylinder fins are particularly important for improving thermal efficiency and stability, as they are critical components that withstand thermal shock and corrosion.

[0003] Traditional heat-resistant steel fins cannot effectively dissipate heat under high-temperature conditions, resulting in insufficient stability and susceptibility to high-temperature oxidation and corrosion, leading to performance degradation and shortened service life. Summary of the Invention

[0004] To solve the above-mentioned technical problems, this utility model provides a protective device for the inner cylinder fins of a preheater.

[0005] This utility model is achieved using the following technical solution: a protective device for the inner cylinder hanging plates of a preheater, comprising a working cylinder, a feed inlet at the top of the working cylinder, an air outlet at the front end of the working cylinder, a drive motor at the right end of the working cylinder, a limit plate on the surface of the working cylinder, a protective block inside the working cylinder, a connecting plate one at the front end of the working cylinder, a screw at the front end of the connecting plate one, a fixing plate at the front end of the working cylinder, a drive fan at the rear end of the working cylinder, an air inlet pipe on the surface of the protective block, a connecting plate two on the surface of the working cylinder, and a discharge port at the bottom end of the working cylinder.

[0006] Through the above technical solution, by setting up a working cylinder, these components work together to protect the preheater inner cylinder fins from damage.

[0007] As a further improvement to the above solution, a feed inlet is provided at the top of the working cylinder, and the rear end of the air outlet is fixedly connected to the front end of the working cylinder.

[0008] The above technical solution allows for the discharge of residual hot air from the working cylinder after preheating, which can be released for future use. The air outlet can also be used to discharge preheated materials.

[0009] As a further improvement to the above solution, the left end of the drive motor is fixedly connected to the right end of the working cylinder, and four limiting plates are provided, with one end of the four limiting plates close to each other being fixedly connected to the surface of the working cylinder.

[0010] The above technical solution involves setting a drive motor and a limiting plate. The drive motor is fixedly connected to the right end of the working cylinder through its left end, providing power to rotate the working cylinder. The limiting plate is set on the surface of the working cylinder to limit the rotation range of the working cylinder and ensure that it works within a safe angle.

[0011] As a further improvement to the above solution, the ends of the protective blocks that are far apart from each other are fixedly connected to the ends of the inner wall of the working cylinder that are close to each other.

[0012] The above technical solution involves setting up protective blocks inside the working cylinder. These protective blocks are fixedly connected to the inner wall to prevent the hanging plates from colliding and being damaged when they rotate at high speed.

[0013] As a further improvement to the above solution, a number of screws are provided, and the screws are threadedly connected to the front end of the working cylinder through a connecting plate. Two fixing plates are provided, and the ends of the two fixing plates that are close to each other are fixedly connected to the surface of the working cylinder.

[0014] The above technical solution involves setting up a connecting plate, which is connected to the front end of the working cylinder by screws, ensuring a firm connection. After preheating, it can be removed for heat dissipation.

[0015] As a further improvement to the above solution, the front end of the drive fan is connected to the rear end of the drive motor, the rear end of the air inlet pipe is fixedly connected to the front end of the drive fan, and the front end of the air inlet pipe is fixedly connected to the inner wall of the working cylinder.

[0016] The above technical solution involves setting up a drive fan, which is connected to the rear end of the drive motor via a transmission connection. The drive fan is responsible for drawing in external air and delivering it to the inside of the working cylinder through the air inlet pipe to cool and clean the environment inside the cylinder.

[0017] As a further improvement to the above solution, two connecting plates are provided. The ends of the two connecting plates that are far apart from each other are fixedly connected to the inside of the working cylinder, and the top of the discharge port is fixedly connected to the bottom of the working cylinder.

[0018] By using the above technical solution, and by setting two connecting plates 2, which are fixed inside the working cylinder and connected to the discharge port, the cylinder can be disassembled after the material flows out, and the internal structure can be inspected and repaired, thereby extending the service life of the equipment.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] This utility model can discharge the remaining hot air inside the working cylinder after preheating by setting an air outlet for the next use. The air outlet can also be used to discharge preheated materials. By setting a drive motor and a limiting plate, the drive motor is fixedly connected to the right end of the working cylinder through its left end to provide power to rotate the working cylinder. The limiting plate is set on the surface of the working cylinder to limit the rotation range of the working cylinder and ensure that it works within a safe angle.

[0021] By setting protective blocks, protective blocks are installed inside the working cylinder. These protective blocks are fixedly connected to the inner wall to prevent the hanging plates from colliding with and being damaged when rotating at high speed.

[0022] This utility model provides a connecting plate, which is connected to the front end of the working cylinder by screws, ensuring a firm connection. After preheating, it can be removed for heat dissipation.

[0023] By setting up a drive fan, which is connected to the rear end of the drive motor through a transmission connection, the drive fan is responsible for drawing in external air and delivering it to the inside of the working cylinder through the air inlet pipe to cool and clean the environment inside the cylinder.

[0024] By setting two connecting plates, which are fixed inside the working cylinder and connected to the discharge port, the cylinder can be disassembled after the material flows out, allowing for internal structure maintenance and extending the service life of the equipment.
