[0002] Composite materials are new materials created by combining different material components using advanced material preparation technologies. During the production of composite materials, vacuum distillation is required to separate and purify the materials. Vacuum distillation is an important method for separating and purifying compounds, especially suitable for separating and purifying high-boiling-point substances and compounds that have already decomposed, oxidized, or polymerized before reaching their boiling point during atmospheric distillation.

[0003] Polyurethane resin is extracted using distillation equipment. During the extraction and processing of vacuum distillation equipment, most distillation equipment only uses a single set of condenser collection mechanisms. After distillation, it is inconvenient to separate the materials according to different condensation temperatures, thus affecting the flexibility and efficiency of the extraction.

[0004] There is an urgent need for a vacuum distillation apparatus for UV-resistant polyurethane resin used in composite materials to address the technical deficiencies mentioned above. Utility Model Content

[0008] As a further technical solution of this utility model, a connecting pipe is installed at the bottom right end of the first condenser tube, and the connecting pipe is connected to the top end of the second condenser tube.

[0009] As a further technical solution of this utility model, the exhaust channel is installed at an angle inside the first condenser tube and the second condenser tube.

[0010] As a further technical solution of this utility model, a pressure monitor is installed on the safety bottle, and a cooling component is installed inside the safety bottle.

The condensed material enters the interior of the first collection box through the discharge pipe of the first condenser. The uncondensed gas enters the interior of the second condenser through the exhaust channel. The condensation temperature of the second condenser can condense and extract the gas.

When the liquid level of the material collected in the first collection box and the second collection box reaches the detection position of the liquid level sensor, the liquid level sensor will give timely feedback, and then the electromagnetic discharge pipe on the first collection box and the second collection box can be opened to discharge the material. This structure realizes the function of convenient timely discharge and collection. Attached Figure Description

The conveying pipe 10 is connected to the input end of the first condenser pipe 11.

The bottom right end of the second condenser pipe 16 is connected to a safety bottle 17 through a pipe. A first collection box 14 is provided below the first condenser pipe 11. A second collection box 20 is provided below the second condenser pipe 16. Both the first collection box 14 and the second collection box 20 are provided with a liquid level sensor 24 inside. Both the first collection box 14 and the second collection box 20 are provided with an electromagnetic discharge pipe 25 on their sides.

[0025] Water inlet pipes 22 are installed at the top of the first condenser pipe 11 and the second condenser pipe 16, and water outlet pipes 23 are installed at the bottom of the first condenser pipe 11 and the second condenser pipe 16. The exhaust channel 21 is installed at an angle inside the first condenser pipe 11 and the second condenser pipe 16. A connecting pipe 15 is installed at the bottom right side of the first condenser pipe 11, and the connecting pipe 15 is connected to the top of the second condenser pipe 16.

[0026] Specifically, such as Figure 1 and Figure 3 As shown, the condensation temperature of the first condenser 11 can condense the material to be extracted into a liquid. The condensed material enters the interior of the first collection box 14 through the discharge pipe 13 of the first condenser 11. The uncondensed gas enters the interior of the second condenser 16 through the exhaust channel 21. The condensation temperature of the second condenser 16 can condense and extract the gas.

[0027] The first collection box 14 is connected to the discharge pipe 13 at the bottom of the first condenser 11, the second collection box 20 is connected to the discharge pipe 13 at the bottom of the second condenser 16, and the liquid level sensor 24 is electrically connected to the electromagnetic discharge pipe 25.

[0028] Specifically, such as Figure 1 and Figure 2As shown, when the liquid level of the material collected inside the first collection box 14 and the second collection box 20 reaches the detection position of the liquid level sensor 24, the liquid level sensor 24 provides timely feedback, and then the electromagnetic discharge pipe 25 on the first collection box 14 and the second collection box 20 can be opened to discharge the material.

[0031] Working Principle: In use, the material to be processed is first poured into the distillation vessel 2, and then the sealing cap 5 is installed on the distillation vessel 2. The distillation vessel 2 then begins to heat and distill the material inside. During distillation, the drive motor 7 drives the stirring shaft 4 and stirring blades 3 to stir the liquid inside the distillation vessel 2. Continuous and gentle stirring during distillation prevents the liquid from boiling over. During stirring, the mechanical seal assembly 6 maintains a sealed environment inside the distillation vessel 2, preventing external air from entering. The condensation temperature of the first condenser 11 condenses the material to be extracted. The liquid, after condensation, enters the first collection box 14 through the discharge pipe 13 of the first condenser 11. The uncondensed gas enters the second condenser 16 through the exhaust channel 21. The condensation temperature of the second condenser 16 can condense and extract the gas.
