Headstock for hanging of rotary filter
Kunorza, Michal ; Mazal, Pavel (referee) ; Brandejs, Jan (advisor)
The purpose of this bachelor thesis is to design headstock for hanging of rotary filter. First part deals about possibilities of hanging drum to supporting frame and choice of suitable transmiting element. Then it was provided experimental measuring of coefficient of sliding friction between flat belt, which is used to hanging of drum, and surface of stainless sheet in case of different rough surfaces and in case of different working conditions. Second part focuses on the design headstock for hanging of rotary filter and economical evaluation of fabrication.
