Description
Technical field
The utility model relates to roasting apparatus fields, more particularly to a kind of anti-sticking wall cylinder roaster.
Background technique
Roaster is widely used in the roasting to various materials, and the pattern of roaster is also varied, there is cartridge type, case
Material to be roasted when using cylinder roaster, is usually first placed in the furnace tube of cylinder roaster, by right by formula, tubular type etc.
Burner hearth heating, while the furnace tube of roaster is rotated, to achieve the purpose that heat furnace tube roasting material.
When roasting some materials, material is heated reach certain temperature after be easy to stick on the furnace wall of furnace tube, glue
Wall phenomenon glues the material of wall because heated close to furnace tube wall, roasts first complete at the appointed time, and continuing to roast can be burned, and
Because heat is obstructed product standard is not achieved, therefore not only affect product quality in the material of not viscous wall at the appointed time, and
And cause the waste of material and heat resource.
Currently, mainly prevent viscous wall by manually beaing furnace tube outer wall, manually beaing must be close to roaster and makees in real time
Industry, it is uneven because manually beaing, still remain wall sticking phenomenon, it is often necessary to shut down cleaning, extend firing cycle, and high temperature
Operation has damage human body.Other field has the setting on the cylinder outer wall of dryer to hang hammer or the column hammer with sliding rail, iron hammer
Or column hammer rotates with roller and is driven rise, then falls or glides by self gravity, the impingement position of iron hammer or column hammer
It can be only positioned at as on side wall, viscous wall material is not easy to glue wall by abate or again；Meanwhile extension hammer or column are hammered into shape because space is limited,
The kinetic energy for being by self gravity potential energy is just small, causes the dynamics of beaing inadequate, still remains wall sticking phenomenon；There are also use three
Angle sliding rail jacks up column hammer, so that column hammer is fallen and beat furnace tube wall, but because triangular guide rail production height is by furnace tube and cooperation furnace tube
The spacing of the transmission device of rotation limits, and causing column hammer to beat, dynamics is inadequate, and material is not easily to fall off；All there is iron hammer in above-mentioned design
Or the position of beaing of column hammer is certain or a few places on furnace wall, beats that position is uneven, beats the inadequate defect of dynamics, glues wall
Material is not easy to be shaken to fall, and anti-sticking wall effect is bad.
