Description

TECHNICAL FIELD

[0001] The present application relates to the field of cement production, in particular to a new type of high-temperature wear-resistant valve plate for the tertiary air pipe. BACKGROUND

[0002] The new type of high-temperature wear-resistant valve plate for the tertiary air pipe is a key component specially designed for the tertiary air pipe system in industrial environments such as cement production. It can work stably for a long time in high-temperature environments and has excellent wear resistance, which can effectively resist the erosion of dust-containing air flow. In the cement production process, the main function of the tertiary air pipe is to transport hot air from the cooler to the decomposing furnace to provide the required oxygen for fuel combustion. By changing its opening degree, the new type of high-temperature wear-resistant valve plate for the tertiary air pipe can accurately adjust the air volume entering the decomposing furnace.

[0003] In high-temperature environments (usually the temperature in the tertiary air pipe can reach 800-1000℃ or even higher), even high-temperature resistant materials can undergo oxidation reactions. The metal material on the surface of the valve plate combines with oxygen in the air to form an oxide layer. If the oxide layer is loose, it will continuously peel off, causing the loss of the valve plate body material. Moreover, in the cement production process, the gas composition in the tertiary air pipe is complex and may contain corrosive substances such as sulfur oxides, which can accelerate the corrosion of the valve plate material and reduce the overall service life of the valve plate, affecting the control of air circulation in the tertiary air pipe.

[0004] In view of the above-mentioned related technology, the inventors believe that the raft is affected by gas corrosion during use, therefore, a new type of high-temperature wear-resistant valve plate for the tertiary air pipe is proposed to solve the above problems. CONTENT OF THE INVENTION

[0008] Preferably, the limiting mechanism comprises a fixed slot symmetrically opened on the upper and lower end portions of the back surface of the valve plate body, a limiting plug symmetrically movably installed inside the fixed slot, and an outer connecting block welded outside the limiting plug extended to the outside of the fixed slot, and a spring installed inside the fixed slot between the two outer connecting blocks.

[0009] Preferably, the limiting plug is extended to the limiting block inside the limiting slot through the fixed slot, and the limiting hole and the limiting plug are mutually clamped.
