Description

Technical Field

[0001] The utility model relates to the field of cement kiln clinker burning system, in particular to a novel valve plate device for a high-temperature gate valve of a tertiary air duct in cement clinker production. Background Art

[0002] With the continuous growth of the national economy, the market for building materials such as cement, steel, and stone has shown an oversupply in recent years. Against this background, enterprises are facing huge challenges in their development, especially for energy-intensive enterprises such as cement production, whose operating costs are constantly rising, making energy conservation and consumption reduction the key to the survival and development of enterprises.

[0003] In the cement clinker production process, the supply and utilization of heat are important factors to ensure production efficiency and product quality. Since the heat is mainly concentrated in the kiln head, in order to enable other production systems to reasonably and effectively utilize this heat, the heat is usually transported through hot air ducts. In this process, the high-temperature gate valve plays a key role in regulating the air volume to ensure the reasonable distribution and utilization of heat.

[0004] However, the traditional gate valve disc performs poorly in high temperature environments and its service life is often short. Under high temperature conditions, the valve disc is prone to breakage, which not only makes it impossible to adjust the hot air volume in the production system, thus affecting the normal operation of the system, but may even cause the system to shut down and stop production in severe cases, causing huge economic losses to the company.

[0005] Therefore, in order to solve the problem of easy breakage of the valve plate of the high-temperature gate valve in cement clinker production, the cement industry urgently needs to develop a new valve plate device to improve its high temperature resistance and service life. The new valve plate device not only needs to have good structural strength and stability, but also needs to be easy to install and maintain to ensure the stable and efficient operation of the cement production system.

[0006] Therefore, it is necessary to provide a new type of valve plate device for high-temperature gate valve of tertiary air duct in cement clinker production to solve the above technical problems. Utility Model Content

[0011] Preferably, a lifting ear is provided on each side of the upper part of the main support plate, and the lifting ear is connected to the main support plate through an ear plate vertical plate. The strength of the ear plate vertical plate is reinforced by ear plate ribs on both sides to facilitate the lifting and installation of the valve plate device.

[0012] Preferably, the upper part of the valve plate, the lower part of the valve plate and all related parts are cast, have high strength, and are not easy to break during use, thereby improving the overall durability and reliability of the valve plate device.

[0013] Preferably, the transverse ribs and longitudinal ribs are designed with an optimized layout so that the valve plate body can be evenly distributed when subjected to stress, thereby improving the bearing capacity of the valve plate device and reducing the risk of damage due to stress concentration.

[0014] Preferably, the flange, bolts and nuts are made of high-strength materials and are specially treated to improve their resistance to high temperature and corrosion, ensuring that the valve plate device can operate stably for a long time in a high temperature, high humidity and high corrosion environment.

[0015] Compared with the related art, the new valve plate device for high-temperature gate valve of tertiary air duct in cement clinker production provided by the utility model has the following beneficial effects:

[0016] Firstly, by adopting a unique valve plate structure design, including the combination of the upper and lower parts of the valve plate, and the arrangement of the transverse ribs and longitudinal ribs on the valve plate body, the structural strength and stability of the valve plate device are significantly improved; this design enables the valve plate device to have stronger pressure resistance in a high temperature environment, reduces the risk of damage caused by stress concentration, and thus extends the service life of the valve plate device;

[0017] Secondly, the device further enhances the overall stability and reliability of the valve plate device through the reinforced design of the main support plate, main support plate rib plate, lifting lug, lug plate vertical plate and lug plate rib plate. This design enables the valve plate device to maintain stable working performance when subjected to harsh environments such as high temperature and high pressure, reduces the possibility of failure, and improves the stability and reliability of the production system.

[0018] In addition, the upper valve plate, lower valve plate and all related parts of the new valve plate device are cast, which has high strength and durability. This material selection not only improves the durability of the valve plate device, but also makes the device less likely to deform or break during long-term use, further ensuring the stable operation of the production system.

[0019] Finally, the design of this device also takes into account the convenience of installation and maintenance; by adopting a modular design, the replacement and maintenance of the valve plate device becomes simpler and faster, reducing maintenance costs and time costs and improving production efficiency.
