Abstract

The invention discloses a rotary kiln sealing device which is arranged between a rotating barrel body of the rotary kiln and a still kiln-head hood of the rotary kiln. The rotary kiln sealing device comprises a sealing hood, a plurality of fish scale pieces, a tensioning steel-wire-rope, a plurality of steel-wire-rope positioning hooks and two balance weights. The sealing hood comprises a fixed plate and a sealing plate which is fixedly connected with the fixed plate, and the central portion of the sealing plate is provided with a circular-truncated-cone-shaped through-hole coinciding with the axis of the sealing plate. The portion, in contact with an end mouth of the barrel body, of the sealing plate is provided with an annular groove, and the annular groove is internally provided with a first sealing pad. First ends of the fish scale pieces are fixedly connected with the circumferential face of the sealing plate, and the lower surfaces of second ends of the fish scale pieces are in contact with the outer surface of the rotary kiln barrel body. According to the rotary kiln sealing device, a sealing platform is designed as a circular-truncated-cone-shaped structure, the fish scale pieces are convenient to install and are fixed in the width directions, and the fish scale pieces are made to be in close fit with the sealing hood, the resistance is reduced, and the good sealing effect of the sealing device is guaranteed.

Description

technical field [0001] The invention relates to rotary kiln technology. More specifically, the present invention relates to a sealing device for a rotary kiln. Background technique [0002] Rotary kiln refers to rotary calcining kiln (commonly known as rotary kiln), which belongs to the category of building materials equipment. Rotary kiln can be divided into cement kiln, metallurgical chemical kiln and lime kiln according to different materials. Cement kilns are mainly used for calcining cement clinker, which can be divided into two categories: dry production cement kiln and wet production cement kiln. There is inevitably a gap between the rotating cylinder of the rotary kiln and the cover of the kiln head and kiln tail. In order to prevent the outside air from being sucked into the rotary equipment or the gas carrying materials in the rotary equipment from leaking out, the cylinder of the rotary kiln There must be a sealing device between the cover and the cover. The se...
