Abstract
The utility model provides a clamping sleeve sealing device for an external heated type rotary furnace. The clamping sleeve sealing device is formed by connecting units with the same structure. Each unit comprises an aligning bolt, a door-shaped frame, a spring, wedge iron, a pressing plate and a graphite sealing block, wherein the wedge iron is fixed on a clamping sleeve flange, the door-shaped frame is installed between two pieces of adjacent wedge iron and is fixed with the wedge iron on the two sides through the spring and the aligning bolt, the graphite sealing block is installed below the wedge iron and the door-shaped frame, the other side of the graphite sealing block is provided with the pressing plate, and the graphite sealing block is fixed between the clamping sleeve flange and the pressing plate. The clamping sleeve sealing device can ensure that an eternal heating clamping sleeve is sealed tightly, safely and reliably, and heating efficiency is improved.
Description
Technical field
The utility model relates to a kind of chuck sealing device of external heat type rotary furnace.
Background technology
In the industries such as chemical industry, metallurgy, building materials, Roarykiln is widely used in the drying, reaction of material, the operation such as cooling.In the drying and course of reaction of rotary furnace, generally need to provide heat by heat-carrying agent.Whether can directly contact with material according to heat-carrying agent, be divided into two kinds of rotary furnaces of internal heat type and external-heat.External heat type rotary furnace is normally at rotary furnace cylindrical shell arranged outside chuck, and conveying high temperature heat-carrying agent provides heat to reaction in furnace or dry run in chuck.In working order, the rotary furnace cylindrical shell is to need rotation, and the external heat chuck connects external pipeline due to needs, normally static fixing, fixing external heat chuck and the chuck sealing device between rotary barrel are vitals on external heat type rotary furnace, how to design a safe and reliable chuck sealing external heat type rotary furnace is played crucial effect.
Summary of the invention
The purpose of this utility model is to provide a kind of chuck sealing device for external heat type rotary furnace, can guarantee that the sealing of external heat chuck is tight, safe and reliable, has improved the efficiency of heating surface.
The technical solution of the utility model is: a kind of chuck sealing device for external heat type rotary furnace, it is characterized in that described chuck sealing device is connected and composed by the same structure unit, each unit comprises adjusting threaded spindle, door type frame, spring, drift, pressing plate, graphite grazing piece; Drift on each unit is fixed on jacket flange, and door type frame is arranged between two adjacent drifts, and is fixed together by the drift on spring and adjusting threaded spindle and both sides; The graphite grazing piece is arranged on the below of drift and door type frame, and the another side of graphite grazing piece arranges pressing plate, and the graphite grazing piece is fixed between jacket flange and pressing plate.
The chuck sealing device that the utility model provides can guarantee that the sealing of external heat chuck is tight, safe and reliable, has improved simultaneously the efficiency of heating surface.
