Technical Field
[0001] This utility model relates to the field of chemical separation equipment technology, and more specifically, to a rotary scraped membrane molecular distillation separation device. Background Technology
[0002] Molecular distillation is a non-equilibrium continuous distillation technique performed under high vacuum conditions. Its principle is based on the difference in the free path of molecular motion between different substances, achieving efficient separation at temperatures far below the boiling point under normal pressure. This technique has advantages such as low operating temperature, short heating time, and high separation efficiency, and is widely used in the purification of heat-sensitive substances in the food, pharmaceutical, and cosmetic industries.

Furthermore, traditional equipment has poor adaptability to high-viscosity materials and struggles to achieve continuous and stable operation. Therefore, in view of this, the inventors have researched and improved upon existing structures to provide a rotary scraped-film molecular distillation separation device, aiming to achieve greater practical value.

[0026] Example:
[0027] Please see Figure 1-4 A rotary scraper molecular distillation separation device includes a tank body 1 and a heating cylinder 10. The heating cylinder 10 is installed inside the tank body 1.

An anti-collision pad 8 is fixed on the outside of the protective sleeve 2. A handle 9 is provided on the top of the protective sleeve 2. A motor 11 is installed at the middle position of the bottom of the tank body 1. A rotating shaft 12 is driven to the upper output end of the motor 11. An installation sleeve 13 is fixed on the outside of the rotating shaft 12. An installation frame 14 is fixed on one side of the installation sleeve 13. An arc-shaped scraper 15 is bolted to one side of the installation frame 14.
[0028] See Figure 1 and Figure 3 A controller is installed on the back of the tank body 1, and a discharge port is installed at the bottom of the tank body 1. A lock 101 is fixed on the outside of the tank body 1. The tank body 1 is a sealed container. The outer surface of the heating cylinder 10 is mirror polished and serves as the material evaporation surface.
[0029] See Figure 1 and Figure 3 The outer side of the can lid 3 is bolted with a buckle 31, which is matched with the latch 101. The buckle 31 and the latch 101 are used to ensure that the can lid 3 is reliably sealed.
[0030] See Figure 3 and Figure 4The arc-shaped scraper 15 is symmetrically arranged on the outside of the mounting sleeve 13, and the arc-shaped scraper 15 is made of high temperature resistant silicone rubber material. The arc-shaped scraper 15 is made of high temperature resistant silicone rubber and rotates with the motor 11 to scrape the material into a thin film evenly.
[0031] See Figure 1 and Figure 2 The anti-collision pads 8 are provided in four sets, which are distributed in a ring around the outside of the protective sleeve 2, and both the anti-collision pads 8 and the protective sleeve 2 are made of rubber material.
[0032] See Figure 1 and Figure 3 An insulation layer is provided between the heating cylinder 10 and the tank body 1, and a feed inlet 7 is installed on the upper part of the tank cover 3. The insulation layer is used to increase the insulation effect of the heating cylinder 10.
[0033] See Figure 1 and Figure 2 The water tank 4 has a heat-conducting pipe 16 installed inside in a ring shape.

At this time, the motor 11 drives the rotating shaft 12 to drive the arc-shaped scraper 15 to rotate at high speed, so as to evenly coat the material into a thin film. Under vacuum and heating conditions, the light components evaporate and rise rapidly, and are introduced into the heat-conducting pipe 16 through the gas supply pipe 6. After being condensed through the heat-conducting pipe 16, they are discharged through the exhaust pipe. The heavy components flow down along the inner wall of the heating cylinder 10 and are discharged from the discharge port, thus completing the efficient separation. The device has a reasonable structure, stable operation, and high separation efficiency. It is especially suitable for the high-quality purification of high-boiling-point and heat-sensitive materials.
