Specific embodiment
The utility model provides a kind of active-feeding formula sludge extrusion pelletizer, to make the purpose of this utility model, technology
Scheme and effect are clearer, clear, and the utility model is further described as follows in conjunction with drawings and embodiments.It should
Understand, specific embodiment described herein only to explain the utility model, is not used to limit the utility model.
The utility model provides a kind of active-feeding formula sludge extrusion pelletizer referring to FIG. 1-2, comprising: feed bin 1, if
Set the feeding mechanism 2 below feed bin 1, the shaping mechanism 3 being arranged in below feeding mechanism 2 and respectively with feeding mechanism 2 and
The driving part 4 that shaping mechanism 3 connects；The feeding mechanism 2 includes first rotating shaft 21, the second shaft 22, is axially disposed within the
3 first feeding rollers 23 in one shaft 21 and 3 second feeding rollers 24 being axially disposed in the second shaft 22, the drive
The output end and first rotating shaft 21 of dynamic component 4 or the second shaft 22 are sequentially connected, and pass between first rotating shaft 21 and the second shaft 22
It is dynamic to be synchronized using mitre gears, 22 rotation, and the center line position of the two opposite to each other of the first rotating shaft 21 and the second shaft
In in same horizontal line, first feeding roller 23 and the second feeding roller 24 are placed equidistant with, and are separately fixed at 21 He of first rotating shaft
It in second shaft 22, and links respectively with first rotating shaft 21 and the second shaft 22, the first feeding roller 23 and the second feeding roller 24 exist
Heterogeneous Permutation in rotary motion trace.
