Description
Technical field
The present invention relates to delivery heat transfer equipment, more particularly to a kind of spiral heat exchange required to sealing and is set conveyer
The screw conveyor shaft being placed on spiral heat exchange conveyer.
Background technology
It is industrial often to have some reactor operations, it is necessary to which internal environment and external environs, realize internal thing
Material is continuous to be output to external environment condition, and material needs efficiently to realize heat exchange in a short time.Such as returned using external-heat
When rotary kiln does the processing of organic matter continuous pyrolysis, Non-oxygen pyrolytic environment inside rotary kiln and outside aerobic environment will strictly every
Open, material can not be such that extraneous air enters inside rotary kiln after being pyrolyzed during caused carbon slag discharge, the pyrocarbon slag of discharge
Quickly to be cooled down under oxygen-free environment.Existing common way has：
1st, carbon slag is cooled to by normal temperature using conventional drum type lag cooler.It is interior but conventional rollers lag cooler filling rate is small
Portion's airborne dust, easily explosive dust atmosphere is formed, it is necessary to be passed through nitrogen protection；And conventional rollers lag cooler roller frame, charging
Front shroud moves with discharging hood opposing roller, it is difficult to which realization is fully sealed, easy invading air, is rolled from pyrolysis furnace discharge to tradition
Cylinder lag cooler needs to install Star-like unloader or double push-pull valves to prevent extraneous air from invading.And Star-like unloader is in the mistake of rotation
In journey or a certain amount of air can be brought into in stove, double push-pull valves are alternately opening valve, completely cut off the operation of internal and external environment
Journey also has a small amount of air and entered in stove.
2nd, installation is tilted using traditional water jacket heat exchange conveying worm, controls transporting velocity, it is ensured that material is arranged all the time at bottom
Fill up, completely cut off extraneous air, connected with more water jackets heat exchange conveying worms, carbon slag is cooled down.But traditional water jacket spiral transferring
Machine is sent, coolant flows through in outer collet chuck layer and helical axis intervalve, too small with the heat exchange area of material.In addition, traditional water jacket spiral shell
The helical blade of rotation conveyer is directly welded on central shaft, and when temperature is too high, thermal stress is larger, easily produces thermal deformation.
In summary, the low screw conveyor shaft of a kind of heat exchange efficiency height, thermal deformation degree how is provided and including the spiral
Conveying axis and sealing effect it is good spiral heat exchange conveyer, into the technical problem of those skilled in the art's urgent need to resolve.
The content of the invention
In view of this, one of the problem to be solved in the present invention is how to provide that a kind of heat exchange efficiency is high, thermal deformation degree is low
