Abstract

The invention discloses a film evaporator, and relates to the field of solution concentration equipment. The film evaporator comprises an evaporation cylinder body with a material inlet and a materialoutlet, a pushing screw with a rotating frame arranged in the evaporation cylinder body, a drive component used for driving the pushing screw to rotate, and a heating device used for heating the evaporation cylinder body, wherein the pushing screw is at least provided with two pushing helixes, and each pushing helix is provided with a liquid guide groove. The invention provides the film evaporator, the operation is convenient, the film formation is stable, fewer bubbles are produced, an organic solvent is fully separated, and the product quality is favorably improved.

Description

technical field [0001] The invention relates to the field of solution concentration equipment, in particular to a thin film evaporator. Background technique [0002] Thin film evaporator is a type of evaporator, its characteristic is that the material liquid flows along the wall of the heating tube in a film shape to conduct heat transfer and evaporation, the advantages are high heat transfer efficiency, fast evaporation speed, and short material residence time, so it is especially suitable for Evaporation of heat-sensitive substances, suitable for concentration of dilute solutions in pharmaceutical, food and chemical industries. [0003] The utility model patent with the existing patent notification number CN205182213U discloses a thin film evaporator, which includes a motor connected to a reducer, an evaporation cylinder is arranged under the reducer, a rotating shaft is arranged in the evaporation cylinder, and a spiral distribution is arranged on the rotating shaft. The...
