Problems solved by technology

The average service life of the traditional three-stage air valve can only be used for about 6 months. The specific problems are: 1. The skeleton is deformed and stuck, 2. The castable is peeled off in large pieces, 3. The external material is burst
When the valve plate is deformed and damaged, the air volume of the tertiary air cannot be adjusted, and the operation and adjustment of the system are inconvenient, which seriously affects the output and quality of the kiln system

Abstract

The invention relates to a novel tertiary air gate valve plate of a dry process cement rotary kiln. The novel tertiary air gate valve plate comprises a valve plate body with the cross section being composed of four edges, wherein the three edges are straight lines, and the other one edge is an arc. The straight line opposite to the arc is provided with lifting lugs. The valve body is made of corundum mullite castable. The novel tertiary air gate valve plate is not prone to being peeled off, abrasion resistant and scouring resistant.

Description

technical field [0001] The invention relates to a valve plate, in particular to a novel dry-process cement rotary kiln damper valve plate. Background technique [0002] In the new dry process cement kiln, the tertiary air valve mainly adjusts the opening of the tertiary air valve, which can not only ensure the oxygen content required for the combustion of calciner coal, but also ensure sufficient ventilation in the rotary kiln, so that the two can be kept at a reasonable level. matching key equipment. The average service life of the traditional three-stage air valve can only be used for about 6 months. The specific problems are: 1. The skeleton is deformed and stuck, 2. The castable is peeled off in large pieces, and 3. The external material is burst. When the valve plate is deformed and damaged, the air volume of the tertiary air cannot be adjusted, and the operation and adjustment of the system is inconvenient, which seriously affects the output and quality of the kiln sy...
