Steep Belt Conveyor to Transport Crushed Building Rubble
Koiš, Jiří ; Kašpárek, Jaroslav (referee) ; Škopán, Miroslav (advisor)
The objective of this bachelor is the design of construction debris steep conveyor belt. The work deals with the solution concepts proposal and individual components design that are motivated by functional device calculation. Furthermore, the design of a belt tensioning mechanism and control calculation of the exposed parts is proposed. The work is accompanied by the supporting frame structure design. Moreover the conveyor installation and operation conditions are suggested. Summary and author comments are enclosed at the end. The conveyor assembly drawing and tensioning mechanism subassembly drawing is attached.

Computational Model of KWH Boiler
Koiš, Jiří ; Skála, Zdeněk (referee) ; Lisý, Martin (advisor)
The subject of this thesis is the computational model of existing KWH boiler. There is a short research in the introduction, which deals with combustion heat of considered boiler. The stoichiometric and balance calculations of gasification chamber ZKG are performed first. The Balance calculations are based on the boiler thermal loss calculations, the losses were determined experimentally. The entire calculation is processed in a computational program for purposses of debugging and manipulation with partial calculations. The computational model that is proposed in this thesis provide better boiler proces understandig. The real boiler measurement is performed for evaluation. The next point is the result analyses, that shows potential boiler efficiency improvements.

Design of the extruder for additive manufacturing of highly-filled thermoplastics
Kočař, Jiří ; Koiš, Jiří (referee) ; Škaroupka, David (advisor)
The diploma thesis is concerned in design and realization of an experimental extruder for high-filled thermoplastic (Polybet) extrusion, which is a part of an assembly attached to the robotic arm. The result of the work is a device, that is be able to additively and continuously apply layers of Polybet. The s worm threaded extruder with modified parameters is designed with the ability to extrude the thermoplastic melt with additional fillers (sand, glass). The dimensions and weight of the extruder were minimized within limits of the robotic arm carrying capacity. The design of this thesis is an extruder which is able of large-scale additive printing of Polybet with binders (PET or PP). Another result is a mathematical model of material flow and power consumption, adjusted by results of experiments. The thesis is a research of a new part of additive production, where two types of waste material are used for the construction industry. The thesis examines the influence of fillers on power and flow rate through the extruder.
