Equipment for tensioning of mesh on the disc filter segments
Baňoch, Ondřej ; Maňas, Pavel (referee) ; Brandejs, Jan (advisor)
The master thesis deals with mechanical design of device used for stretching and fixing filtration fabric on plastics frames segments for disc filtration device. The thesis was solved in cooperation with IN-EKO Team company that deals with development and manufacturing of filter units. Solution is connected to already ended project FR-T13/699 (end of the year 2013). At the beginning is described the field of filtration devices in broader context with description of the overall functionality these devices and description of used elements in final design. Opening text is followed by concretization of task list and descriptions of concepts variants which are based on FEM analysis of behavior of stretched filtration fabric. The best concept is processed in detail as mechanical design along with pneumatic and PLC control design. Critical part of the design is stretching clamp which was experimentally verified by using experimental clamp in combination with testing machine. The whole design is developed for mass production of disc segments for disc filter which is projected in to the level of the automation.

Measurement of Deflection of Filtration Fabric
Baňoch, Ondřej ; Gajdoš, Petr (referee) ; Brandejs, Jan (advisor)
This bachelor thesis deals with measurements of deflection of filter fabrics of rotating disc filters segment. The main goal is established dependence of deflection of filter fabrics of the pressure at different preload. First part reviews different types of filter devices and their functions. Main focus is on rotation filter discs and their rotation parts. In the next part different filter fabrics are described, different ways of their production and examination of some of their characteristics. The measurements of deflection of fabrics are documented as well as used methodology. In the final part the data obtained from the measurements are evaluated and possible application in manufacture is discussed.
