in order to realize the effect of carrying out specified temperature heat preservation on the pouring environment in the pouring container body, the pouring container body is provided with a heat preservation structure;
the specific form of the heat insulation structure can be as follows:
the perfusion container body consists of a perfusion container inner frame body 120 and a perfusion container outer frame body 110;
an insulating layer is arranged between the inner frame body and the outer frame body of the pouring container;
this mode that heat preservation was realized to heat preservation can be for burying mode such as heater strip underground in the heat preservation and realizing the bulk heating of heat preservation, also can be for the structure as shown in the figure:
namely, the upper part of the filling container body is provided with a heat preservation liquid outlet 111 which can run through the outer frame body of the filling container;
