Problems solved by technology
Both the kiln head shell and the kiln head cover are lined with refractory materials, and the fire viewing holes for observation are opened on the front of the kiln head cover, passing through the refractory material lining. If there are no holes, the strength of the lining will be weakened, and the surface of the hole is rough and it is easy to fall off. Therefore, a brick ring device must be provided to protect and fix the refractory lining. During high temperature use, the combustion status can be observed and controlled.
However, the brick retaining ring currently used cannot effectively protect the refractory lining, and the service life of the lining is still not ideal

The invention discloses an observation hole device on a kiln head cover, comprising a kiln head cover casing (2). The inner side of the kiln head cover casing (2) is provided with a lining (1) made of a refractory material, a communicated observation hole is arranged on the kiln head cover casing (2) and a board surface of the lining (1) made of the refractory material, the observation hole is internally provided with a bell-mouthed brick blocking ring (3) made of a high temperature-resistant metal material, the outer surface of the brick blocking ring (3) is provided with an observation hole seat (4), and the observation hole seat (4) is linked with an observation hole cover (5). The observation hole device is installed at a hole position and plays a role in effectively protecting the lining made of the refractory material and prolonging the service life of the same. By adopting the shapes of the brick blocking ring, the observation hole seat and other parts disclosed by the invention, the lining made of the refractory material can not be easily damaged, and an observation operation is facilitated after the observation hole device is installed.
Description
technical field [0001] The invention relates to a fire viewing hole device on a kiln head cover of a carbon rotary kiln. Background technique [0002] Usually the kiln head of the rotary kiln, the production process is carried out at high temperature and in rotation. The burner and the air required for combustion enter the kiln through the kiln head cover. The kiln hood is also the place where the fire watch workers carry out production operations, so the kiln hood is equipped with fire viewing holes and inspection doors. Both the kiln head shell and the kiln head cover are lined with refractory materials, and the fire viewing holes for observation are opened on the front of the kiln head cover, passing through the refractory material lining. If there are no holes, the strength of the lining will be weakened, and the surface of the hole is rough and it is easy to fall off. Therefore, a brick ring device must be provided to protect and fix the refractory lining. During high...
