Double-tensioning rotary kiln graphite sealing device

Abstract

The invention discloses a double-tensioning rotary kiln graphite sealing device which comprises a sealing frame. The sealing frame comprises a support barrel and an installation barrel; a main body ofthe installation barrel is arranged to be two parallel circular ring shapes; lugs are arranged on corresponding positions on two sides of the two parallel circular ring shapes; a fixed pulley is arranged between each two opposite lugs; wedge blocks are uniformly and fixedly arranged on the circumferences in the middles of the two parallel circular ring shapes of the sealing frame at intervals; acircular arc-shaped graphite block is arranged between each two wedge blocks; a guiding box is arranged on the outer side of each wedge block; a pressing box is arranged between each two guiding boxes; each pressing box presses against the outer side of the corresponding graphite block; a small fixed pulley is arranged on the outer side surface of each pressing box; a steel wire rope winds on eachsmall fixed pulley on the outer side surface of each pressing box; two ends of the steel wire rope wind on the fixed pulleys of the sealing frame; and balancing weight blocks are connected to two ends of the steel wire rope. The double-tensioning rotary kiln graphite sealing device provided by the invention is good in overall structure sealing effect, and the service life of the graphite blocks is long.

Description

technical field [0001] The invention relates to the technical field of sealing devices for mechanical equipment, in particular to a graphite sealing device for a double tension rotary kiln. Background technique [0002] With the improvement of waste incineration system technology, the types of waste incineration are also widening. After burning, various toxic and harmful particles, dust, etc. will leak out along with the sealing device at the kiln head and kiln tail, causing harm to the human body. Relevant industries have higher and higher requirements for the reliability of the sealing structure, so it is necessary to address this According to this market demand trend, design a sealing device with the characteristics of small air leakage coefficient and high reliability. Contents of the invention [0003] The object of the present invention is to provide a double tension rotary kiln graphite sealing device with small air leakage coefficient and high reliability.
