Description
Technical field
The utility model relates to industrial drying equipment field, in particular to a kind of drum dryer self-locking connecting mechanisms.
Background technique
Drum dryer is the cylinder by rotation, and in a manner of heat exchange, the intracorporal material of rotating cylinder is dried
A kind of continous way industrial drying equipment.It is widely used in concrete bone for the purpose of the moisture content for reducing a variety of materials
The drying of the materials such as material, iron ore.Typical drum dryer includes cylindrical shell, transmission system and drive system.Cylinder exists
It is tilted in horizontal direction, external structure is made of rolling ring and support construction, under motor driven effect, is driven, is passed by tugboat
Pass rolling ring, cylinder driven slowly to rotate, material flowed in roller achieve the effect that it is dry.
Currently, in main drum dryer transmission system, design method that there are mainly two types of.
1. drive rolling ring by the power for being applied to tugboat, rolling ring should in radial direction and circumferential direction with drying
Roller tube is connected.Typical drier rolling ring is made of the medium carbon steel for casting or forging.It is processed into smooth circle
Cylindrical surface, then cure process.Using a variety of radial suspension methods, it is flexible coupling together with drier barrel.If
One driving force needs to carry out by rolling ring, drying drum cylinder and rolling ring must closely coupled radial through connector,
Such mode does not just interfere with the purpose that rolling ring is radially hung.Different scientific research institutions and company all devise in practice
A variety of connection methods, required carrying and the adaptation of live load when meeting roller drying.Moreover, in the same of dry materials
When, the surface temperature of roller can also be risen, so need to allow a degree of thermal expansion when design, support connector in this way
It is also required to that generated thermal deformation under thermal expansion long term can be resisted.This is that a kind of ideal ring cutting mode connects, multiple
It will appear very big problem under miscellaneous operating condition.For example in the case where start and stop and failure stopping suddenly, it may increase to system
Add unnecessary pressure.If rolling ring and roller tube be it is hardwired, do not allow to slip because can therefore generate especially
Big torque, to tear the weld seam between connection support plate and rolling ring, so that weld cracking or even cylinder be caused to misplace.Furthermore
Rolling ring is unsatisfactory with the welding for connecting support plate, because the steel used is usually not easy to weld, the weld seam between different materials
It is easy to generate destruction in the case where alternate stress acts on, the existing residual stress of welding itself, cracking are just more serious in addition.?
In technique, it is also necessary to have correctly welding and processing, welding front and back requires to be heated to certain temperature, prevents welding cold cracking
It generates, and because its is bulky, in actual fabrication engineering, heating is costly, and ease for operation is poor, and safety is not also high.
2. individual gear-type transmission ring is arranged far from one end of burner in drying drum, then gear is connected by engagement
It connects on motor, as individual driving mechanism, and rolling ring supporting plate structure only plays support bearing.It can greatly drop in this way
The failure of low rolling ring support plate rupture, but such a structure increases the complexity of system, design cost is increased, needs to solve
A possibility that transmission problem is more, breaks down also increase accordingly.
