The spire of diameter drive shaft, but still there is rubbish to be attached to and be deposited in asking in the surface of drive shaft or the screw wing of spire
Topic.That is, because rubbish normally can not be moved and discharged in the state of garbage dewatering device inside is filled up, can cause
The problem of sanitary fill as described above.
In addition structure as shown in Figure 2 because squeeze it is mobile during rubbish Impact direction and squeeze from rubbish
The discharge direction for the squeezing liquid that pressure goes out is identical, so the water content of block is unsatisfactory, and for easily being compressed
Rubbish, because the discharge of squeezing liquid is not smooth and the problem of the water content difference of discharged block can be caused larger.Elm
It is secondary simultaneously because rubbish can not be by normal movement and discharge, if in order to increase in the state of garbage dewatering device inside is filled up
Add the treating capacity of rubbish and increase the rotary speed of spire, in the squeezing liquid that the direction of rotation along spire is squeezed out
Before completion is automatically drained out, because spire moves forward the moisture content in discharged block can be caused to increase, so as to
The dewater treatment of rubbish can not be smoothly completed.
