▎ 摘　　要

NOVELTY - The device has a sampling tube component whose sampling inlet end is connected to an aerobic reactor and sampling outlet end is connected to a heat insulation mechanism. A holding mechanism is connected to the sampling tube component and jointed to an outside of an aerobic reactor. A heat insulation mechanism is formed with a graphene layer. An inner part of covering core is made of decompression sealing and coating material and formed with an outermost graphene oxide layer. A toughened ceramic layer is arranged at inside of the graphene oxide layer. USE - High-efficient aerobic sampling tube protecting device. ADVANTAGE - The device is simple in structure and convenient to use, and prevents high temperature or cold granular sludge sampling pipe from blocking phenomenon. DESCRIPTION OF DRAWING(S) - The drawing shows a front view of a high-efficient aerobic sampling tube protecting device.
