Embodiment 1
[0027] like Figure 1-5 As shown, a negative pressure molecular distiller includes: a material liquid barrel 1, a barrel cover 2, an evaporation barrel 3, a heating net 4, a blocking plate 5, a condensation air duct 6, and a material liquid pump 7;
[0028] The material liquid barrel 1 is in the shape of a cylindrical container, the bottom surface of the container is conical, the material liquid flows from the middle to the surrounding in the container, and an annular discharge port 11 is provided around the bottom outer ring of the material liquid barrel 1 , During operation, the material liquid falls from the discharge port 11. Since the bottom of the material liquid barrel 1 is conical, the material liquid in the center of the barrel will be replenished around, and an air duct 12 is arranged in the center of the bottom of the material liquid barrel 1. , the height of the air duct 12 is higher than the height of the material and liquid to prevent the entry of the material an...

The invention relates to the technical field of molecular stills, in particular to a negative-pressure molecular still, which includes: a feed liquid barrel, a barrel cover, an evaporation barrel, a heating net, a barrier plate, a condensing air pipe, and a feed liquid pump. The shape of the liquid barrel is a cylindrical container, and the bottom surface of the container is conical. The feed liquid flows from the middle to the surroundings in the container. There is a ring-shaped discharge port around the bottom outer ring of the feed liquid barrel. There is an air duct in the center of the bottom, the height of the air duct is higher than the height of the material liquid, through the cold air flow into the air duct, it can be condensed to form a liquid in the following steps, the lid is a cylindrical cover, and the upper surface is provided with holes It is convenient to pass through the air duct. The present invention heats the material liquid that continues to fall evenly by flowing the material liquid evenly through the heating net area, so that the evaporation is more uniform, and the material liquid can be fully evaporated when passing through the heating net area. The heating of small-capacity material droplet dispersion solves the problem of solid-phase matter during heating.
Description
technical field [0001] The invention relates to an evaporation device for organic materials, in particular to a negative pressure molecular distiller. Background technique [0002] The current distillation method refers to the method of purifying and separating physical liquid and liquid or solid-liquid purification. It occurs under a certain pressure and is accompanied by heat conversion. When the vaporized liquid encounters low temperature, it will liquefy and reduce to liquid. We call this phenomenon distillation. [0003] The general distiller often produces solid-phase substances during the distillation process. Due to the long heating time or the high heating temperature, solid-phase substances may be generated, and cleaning these solid-phase substances is also a big problem. It is often difficult to remove these solids on precision instruments. A little carelessness or excessive cleaning may even lead to the precision and scrapping of precision instruments. [0004]...
