The utility model discloses the structure sealing effect not only obviously but also stable, other if friction sealing device produce the amount of deflection under the high temperature circumstances and produce gap gas leakage because of the rotary furnace carries to foresee easily, the sealed effect of influence, and the utility model discloses flexible construction makes static flange follow -up flange and moves, makes rotary furnace's radial deformation, axial deformation, hoop deformation and amount of deflection deformation all not influence sealed effect.
Description
Technical field
This utility model relates to a kind of rotary furnace sealing device.
Background technology
From the eighties in 20th century, China starts to build Modern sewage treatment plant on a large scale, but ignores the technology in terms of specific resistance to filtration always.Development along with Chinese national economy, industrial wastewater, the discharge capacity of sanitary sewage increase day by day, the sludge quantity produced in sewage disposal process is also increasing, these moisture percentage in sewage sludge are high, content of organics is high, easily rots smelly, if can not get effectively disposing, local environment quality will be had a strong impact on, cause secondary pollution.So the exploitation accelerating to process municipal sewage sludge the research with disposal technology and equipment has become the task of top priority.
At present both at home and abroad the technique of sludge treatment specifically includes that mummification, compost, farmland utilization and Land_use change, burns, fills and other comprehensive utilization (brickmaking, potting grain etc.).Near developed country is progressively carried out along with Environmental capacity, and improving constantly of environmental requirement has formulated higher sludge treatment standard the most about ten years, progressively limits the traditional handicraft such as soil directly application of mud.
Carbonization is one of prevailing technology of specific resistance to filtration instantly, has multiple advantages such as secondary pollution is little, minimizing is obvious.Rotary furnace is the main flow processing equipment of sludge carbonization, and owing to carbonization needs to create anaerobic/anaerobic environment, the sealing property of rotary furnace is the key point realizing technique.
Existing carbonization rotary furnace sealing device generally uses spin friction to seal, and two rubbing surfaces compress or set packing.Such friction sealed device easily produces gap gas leakage because producing amount of deflection under rotary furnace material containing and high-temperature condition, is also easily damaged simultaneously, or need to frequently change encapsulant.Also the rotary furnace having uses noble gas (such as nitrogen) to seal, and this kind of seal structure complex involves great expense, and safeguards frequently simultaneously, and needs uninterrupted nitrogen injection, and operation expense is higher.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, provide a kind of rotary furnace sealing device, flexible structure is added, it is to avoid revolution body of heater produces gap because of radial deformation, axial deformation, circumferential deformation, deflection deformation, breakseal effect by hard sealing.This sealing structure fits tightly with mounting flange by rotating flange and rubs mutually so that in revolution body of heater operation process, sealing is become better and better, and this simple in construction, cheap, remarkably productive, easy to maintenance.
To achieve these goals, this utility model rotary furnace sealing device includes scalable extension spring, rotates flange, mounting flange, stainless steel expansion joint；Described rotation flange fits tightly with mounting flange, and rotation flange is connected with revolution body of heater welded flange by bolt, and revolution body of heater welded flange welds with revolution body of heater comprehensively, to ensure sealing；Mounting flange is connected with the extension spring hanger bracket being located at revolution body of heater discharge end by scalable extension spring, and mounting flange is fixed on discharging casing by stainless steel expansion joint simultaneously；Radial deformation, axial deformation, circumferential deformation and the deflection deformation etc. that produce when turning round body of heater operating all can be absorbed by stainless steel expansion joint and scalable extension spring; fitted tightly with mounting flange by rotation flange again; guarantee to turn round furnace sealing; and along with run in two flanges rub mutually, sealing is become better and better.
Between described mounting flange, stainless steel expansion joint, discharging casing three with bolts；
Described mounting flange is provided with the hanger of several symmetries；
Described revolution body of heater is any kind of rotary furnace；
The described material employing carbon steel rotating flange and mounting flange；
Further, the described hole rotated between flange and mounting flange is marked with high temperature resistant luboil, is used for strengthening sealing effectiveness and playing lubrication.
The beneficial effects of the utility model are:
This utility model sealing structure effect the most substantially but also is stablized, other easily produces gap gas leakage such as friction sealed device because producing amount of deflection under rotary furnace material containing and high-temperature condition, affect sealing effectiveness, and this utility model flexible structure makes the servo-actuated flange of static flange move, the radial deformation of revolution body of heater, axial deformation, circumferential deformation and deflection deformation is made the most not to affect sealing effectiveness；
Being designed by this utility model structure, along with the two continuous friction fit of rubbing surface during rotary furnace running body, sealing is become better and better；
This utility model simple in construction is firm, easy to maintenance, is hardly damaged；Operation expense is cheap, it is not necessary to change accessory.And friction sealed need regularly replace the accessory such as packing or rubbing surface, inert gas seal also needs uninterruptedly to consume noble gas.
