Abstract

The invention discloses a kiln head cover of a rotary kiln, comprising a kiln head sealing device (9) welded with a kiln cylinder (12) into a whole, wherein the other side of the kiln head sealing device (9) is coupled with a kiln head cover body (1), the inner side of the kiln head cover body (1) is provided with a lining (10) made of a refractory material, a rectangular cover gate (2) is arranged on the front side of the kiln head cover body (1), a gate bolt (3) is installed on the cover gate (2), the kiln head cover body (1) and the kiln head sealing device (9) can be mutually disconnected, two sides of the kiln head cover body (1) are respectively provided with a wheel group, and a steel rail (11) is arranged below the wheel groups. Compared with the prior art, the invention ensures that a maintenance worker can enter through the cover gate to perform minor repair on the rotary kiln head, and when major repair is needed, larger maintenance tools and materials can be carried by the maintenance worker and a enough operation space is allowed for the worker to perform maintenance through disconnecting the cover body and the kiln head sealing device and moving the wheel groups by a certain distance on the steel rail.

Description

technical field [0001] The invention relates to a kiln hood of a rotary kiln, which belongs to the technical field of the rotary kiln. Background technique [0002] Generally, the rotary kiln is a thermal equipment for heat treatment of bulk materials, and its 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 the place where fire-watching workers carry out production operations, so the kiln hood is equipped with fire-watching holes and inspection doors. The kiln head cylinder and kiln head cover are lined with refractory materials. Regular inspection and maintenance are required after high-temperature use. Generally, small-scale repairs pass through the inspection door. Due to the limited size of the inspection door opening, if major repairs are required, the inspection door cannot Meet maintenance needs. At this time, a mobile device will be pr...
