Thermal insulation filter for biopharmacy

The utility model relates to a heat preservation filter for biological pharmacy. According to the technical scheme, the filter comprises a filter tank body, a heat preservation shell is arranged on the outer side of the filter tank body, a sealing cover body is hinged to one side of the upper portion of the filter tank body, a liquid inlet and outlet pipe is arranged on one side of the bottom of the heat preservation shell, and the constant-temperature pipeline is arranged on the inner side of the heat preservation shell. The constant-temperature pipeline is used for maintaining the temperature of liquid in the heat preservation shell, and constant-temperature liquid flows in the constant-temperature pipeline. The heat-preservation filter for biopharmacy has the beneficial effects that the heat-preservation shell is matched with the constant-temperature pipeline, so that the temperature of liquid medicine is prevented from being reduced to crystallize, precipitated materials are prevented from blocking the fi
