Bevel edge is fallen, to prevent the generation of blocking phenomenon, reduces the failure rate of whole equipment.In addition, the utility model includes
Components it is relatively very few, overall construction design is relatively reasonable, effectively reduces volume, reduces occupied area.
Detailed description of the invention
Fig. 1 is a kind of schematic view of the front view of direct thermal desorption waterfall type cloth auger reactor of the utility model.
Specific embodiment
Direct thermal desorption waterfall type cloth auger a kind of to the utility model is anti-with reference to the accompanying drawings and detailed description
Device is answered to be described in further detail:
As shown in Figure 1, in this embodiment, a kind of direct thermal desorption waterfall type cloth auger of the utility model is anti-
Device is answered, including driving motor 20, shell 13 and helical axis 15 and helical blade 14 in 13 inner cavity of shell.
Driving motor 20 is mounted on the end of shell 13 by motor cabinet, belongs to conventional commercial product, those skilled in the art
Member, which can according to need, voluntarily to be selected.One end of helical axis 15 is connect by shaft coupling 19 with the shaft of driving motor 20,
The other end is connect by bearing 10 with shell 13, and bearing 10 primarily serves the effect of support and fixation, it is ensured that helical axis 15
With the concentricity of 20 shaft of driving motor, improve service life.Pacify between 13 inner wall of two ends and shell of helical axis 15
Equipped with sealing device 11,18, sealing device 11,18 plays the role of dynamic sealing, this is commercial product, those skilled in the art
It can voluntarily be selected as needed.Helical blade 14 is mounted on the periphery wall of helical axis 15, and with 15 coaxial line of helical axis,
For being conveyed to material.Shell 13 is cylindrical structure, and the internal perisporium of the periphery wall and shell 13 of helical blade 14 is affixed
