Description

Technical Field

[0001] The utility model relates to the field of evaporators, in particular to a variable-spacing short-range molecular evaporator. Background Art

[0002] Short-range molecular distiller is a special liquid-liquid separation device. It is different from traditional distillation, which relies on the separation principle of boiling point difference. Instead, it achieves separation by the difference in the mean free path of the molecular motion of different substances. The molecules of different substances move different distances after escaping from the liquid surface. If a condenser is properly set, the light components will reach the condenser and be condensed and discharged, while the heavy components will not reach the condenser surface and will be discharged in the form of mixed liquid. This device is mainly used for the purification and separation of high-boiling-point and heat-sensitive liquid materials.

[0003] In traditional short-range molecular distillations, the position of the condenser is fixed and difficult to adjust, resulting in a fixed distance between the condenser and the heater. Each distance can only adapt to the separation of one type of substance. If different substances need to be separated, multiple sets of short-range molecular distillations with different distances are required. This is not flexible enough to use and has low practicality.

The heater 4 is a double-layer structure, and the heating medium enters the gap of the double-layer structure of the outer wall of the heater 4 through the heating medium inlet 7 and is discharged through the heating medium outlet 14;

[0026] The heater 4 is fixedly connected to the bottom end of the vertically movable protective cover 2 of the condenser. The bottom end of the heater 4 is connected to a base 3. The heater 4 is internally provided with a condenser 5. According to the properties of the materials to be separated, the optimal spacing and the corresponding lifting height of the condenser 5 are found; the optimal spacing is found to make the separation degree of the materials higher, and the materials that are difficult to separate conventionally are separated. At the same time, the material is heated for a short time, and the distance between the heated liquid surface and the condensing surface is less than the average free path of the light molecules, so the light molecules escaping from the liquid surface reach the condensing surface almost without collision. Therefore, the distillation material is heated for a short time, and the residence time at the distillation temperature is generally between a few seconds and tens of seconds, which reduces the chance of thermal decomposition of the material; the distillation speed is increased, the separation efficiency is improved, and the energy consumption of the heater 4 is reduced;

The fixing seat 62 facilitates the installation and bearing of the driving motor 1. The sliding and interlacing between the guide rod 61 and the top of the vertically movable protective cover 2 of the condenser makes the vertical movement of the condenser 5 more stable. The threaded interlacing between the threaded rod 63 and the condenser 5 cooperates with the interlacing limit of the guide rod 61. Since the driving motor 1 can drive the self-rotation of the threaded rod 63, the self-rotation of the threaded rod 63 can drive the condenser 5 to move vertically up and down inside the vertically movable protective cover 2 of the condenser, so as to provide power for the lifting and lowering movement of the condenser 5.
