Title:
CENTRIFUGE
Document Type and Number:
WIPO Patent Application WO/2017/043247
Kind Code:
A1
Abstract:
Provided is a centrifuge for which manufacturing cost increases can be suppressed by efficiently combining reinforcing fibers with a flexible structure and a protective tube with a rigid structure. A band-shaped nonmetallic fabric 10 woven of high density fibers or the like is wound two to several times on a cooling pipe 5 disposed on the outside of a bowl 4. A cylindrical protector 8 formed from a steel tube is disposed on the outer peripheral side and an insulating layer 6 is formed by filling insulating material with foaming properties from a chemical reaction of polyurethane in a space between the bowl 4 and the cylindrical protector. Here, the width W of the fabric is made smaller than the height Hi of the insulating layer so that the fabric is made to be completely accommodated in the insulating material, with the cooling pipe and fabric made not to come in contact with outside air. Thus, the cylindrical protector can be made thinner because of the reinforcing effect of the fabric.
