The invention discloses a rotary kiln head and kiln tail sealing device which comprises a rotary kiln body. A kiln head feeding port is formed in one side of the rotary kiln body, sealing mechanisms are arranged at the kiln head and the kiln tail of the rotary kiln body, each sealing mechanism comprises a clamped connection mechanism, each sealing mechanism comprises a top end sealing plate, a front end sealing piece and a front end fixing plate, and one side of each top end sealing plate is fixedly connected with one side of the corresponding front end fixing plate through a first fixing bolt. The invention relates to the technical field of rotary kilns. According to the rotary kiln head and kiln tail sealing device, the sealing mechanisms are arranged, movement of two movable side sealing pieces, a fixed side sealing piece and a fixed base of each sealing mechanism is used in cooperation with the corresponding top end sealing plate, the corresponding front end sealing piece, a sealing triangular plate, a top end fixing plate and a sealing gas connector, and therefore the kiln head and kiln tail sealing device is better, the structure is simple and reliable, leakage of materials and smoke can be effectively prevented and controlled, the ecological environment is greatly protected, and meanwhile consumed resources are saved.
Description
technical field [0001] The invention relates to the technical field of rotary kilns, in particular to a rotary kiln head and kiln tail sealing device. Background technique [0002] The rotary kiln is composed of gas flow, fuel combustion, heat transfer and material movement. The rotary kiln is how the fuel can be fully burned, the heat of fuel combustion can be effectively transferred to the material, and a series of processes will occur after the material receives the heat. Physical and chemical changes, and finally form the finished clinker. The metallurgical chemical kiln is mainly used for the magnetization roasting of lean iron ore in the iron and steel plant of the metallurgical industry; the oxidation roasting of chromium and nickel-iron ore; Alumina; chemical plants roast chromium ore and chrome ore powder and other minerals; lime kiln (that is, active lime kiln) is used to roast active lime and lightly burned dolomite for steel plants and ferroalloy plants.
