A heat -preserving jacket for photocatalyst compounding cauldron

The utility model relates to a photocatalyst technical field, in particular to a heat -preserving jacket for photocatalyst compounding cauldron. Heat -preserving jacket fixes the outer wall at the compounding cauldron, by the control of control by temperature change regulating switch, including top layer, fixed heating layer, heat -conducting layer and buffer layer, the fixed heating layer is adopted and is divided the grouped distribution, and every group contains a resistance wire and two springs of coordination, the resistance wire is connected with temperature detect switch, spring of eachcoordination about the resistance wire, the heat -conducting layer is woven wire, evenly distributed anti -skid rubber grain on the buffer layer. The utility model discloses an advantage: the accusetemperature is more accurate, guarantees that the heat of compounding in -process is supplied with, the fixed heating layer possesses the function fixed and heating simultaneously, the heat -conducting layer can pass through t
