In the better embodiment of this practicality, the insulating layer is cellucotton, and the cellucotton wraps up sample crucible.

In another better embodiment of this practicality, the insulating layer is tapetum fibrosum, and the tapetum fibrosum is by sample crucible Package.

In the better embodiment of this practicality, the fiberboard is to push down sample crucible lid；

In another better embodiment of this practicality, the cylinder aoxidizes aluminium material by corundum, mullite or high alumina etc. It is made.

Using above scheme, a kind of microwave Muffle furnace antispray insulation barrel disclosed by the utility model has following technology Effect：

1, crucible cover is pushed down by the weight of antispray insulation barrel staving itself, prevented because of gas pressure liter in sample crucible High open-top crucible cover causes gas leakage excessive, influences experimental result, or even cause sample splash；

2, antispray insulation barrel can be adjusted according to sample crucible outer diameter and embeds alumina fibre cotton or alumina fibre blanket Thickness, minimize the wasted space inside antispray insulation barrel, it is so effective that improve heat insulation effect；

3, antispray insulation barrel can be placed in other attemperators and further increases heat insulation effect, protect original heat preservation Device；

4, the embedded alumina fibre plate of antispray insulation barrel and alumina fibre cotton or alumina fibre blanket can also be square Just replacement, it is simple to operate；

5, the oxidation such as corundum, mullite or high alumina aluminium material cylinder will not be worn in use, and insulation barrel staving uses Long lifespan.

The technique effect of the design of the utility model, concrete structure and generation is made furtherly below with reference to attached drawing It is bright, to be fully understood from the purpose of this utility model, feature and effect.
