Description

Technical Field

[0001] This utility model relates to the field of chemical product manufacturing technology, and in particular to a continuous and efficient purification and distillation apparatus for chemical products. Background Technology

[0002] Distillation in chemical production utilizes the differences in boiling points of components in a liquid mixture to separate and purify them. By heating, the lower-boiling-point components are vaporized, and the fraction is collected after condensation. This process can be used to refine ethanol, fractionate petroleum products, etc. Equipment includes a distillation kettle and condenser, and temperature control is necessary to prevent bumping. Distillation is classified as atmospheric or vacuum distillation, depending on the operating pressure. Vacuum distillation lowers the boiling point and is suitable for heat-sensitive substances. This technology is used in the pharmaceutical and chemical industries for purifying or separating mixtures.

[0003] In the chemical production field, distillation is a key process for purifying substances, directly affecting product quality and production efficiency. Currently, traditional methods often lack proper filtration during material feeding, leading to raw materials containing particulate impurities, polymers, or insoluble substances directly entering the distillation system. This not only easily clogs the distillation vessel, pipes, and condenser, reducing equipment stability, but may also cause safety hazards such as localized overheating and bumping during distillation. Furthermore, the presence of impurities interferes with distillation separation, resulting in decreased fraction purity and affecting the final product quality. Therefore, this invention proposes a continuous and efficient purification distillation device for chemicals to solve these problems. Utility Model Content

The filter screen 18 is installed inside the feeding chamber 5. The moving structure includes a moving plate 19, a mounting cavity 20, a second servo motor 21, a threaded rod 22, a threaded sleeve 23, and a limiting structure. The moving plate 19 is installed above the filter screen 18. The mounting cavity 20 is installed above one side of the feeding chamber 5. The second servo motor 21 is installed at one end of the mounting cavity 20, and the threaded rod 22 is installed on one side inside the mounting cavity 20. The output end of the second servo motor 21 is connected to the threaded rod 22. One end of the threaded rod 22 is connected to a threaded sleeve 23 on its outer wall. One end of the threaded sleeve 23 is connected to one end of the moving plate 19. In use, chemicals are poured into the feed chamber 5 through the feed port 16. The moving plate 19 filters the chemicals. At this time, the second servo motor 21 is started to drive the threaded rod 22 to rotate, thus driving the threaded sleeve 23 to move. Under the limit of the limiting rod 24 and the limiting sleeve 25, the limiting sleeve 25 drives the moving plate 19 to move. The moving plate 19 moves the impurities on the filter screen 18 to both sides, so that the filter screen 18 is not easy to clog during use.

In use, the first servo motor 9 is started to drive shaft 10 to rotate, which in turn drives stirring shaft 11 to rotate, stirring the chemicals inside distillation vessel 3. At the same time, shaft 10 drives connecting rod 12 to rotate, which in turn drives side scraper 13 and bottom scraper 14 to rotate, scraping the walls of distillation vessel 3. This makes cleaning distillation vessel 3 more convenient and faster, ensures uniform heating of materials, prevents local overheating and boiling, accelerates component vaporization and separation, improves distillation efficiency, avoids impurity deposition, ensures fraction purity, and reduces equipment scaling and maintenance.

[0023] Working principle: The operator first pours chemicals into the feed chamber 5 through the feed inlet 16. The moving plate 19 filters the chemicals.

Then, limited by the limiting rod 24 and the limiting sleeve 25, the limiting sleeve 25 drives the moving plate 19 to move. The moving plate 19 moves impurities on the filter screen 18 to both sides, preventing clogging during use. Then, the chemicals enter the steam chamber through the feed inlet 17. Inside the distillation vessel 3, chemicals are heated. At this time, the first servo motor 9 is started to drive the rotating shaft 10 to rotate, which in turn drives the stirring shaft 11 to rotate, stirring the chemicals inside the distillation vessel 3. At the same time, the rotating shaft 10 drives the connecting rod 12 to rotate, which in turn drives the side scraper 13 and the bottom scraper 14 to rotate, scraping the walls of the distillation vessel 3, making it easier and faster to clean. Steam enters the inside of the collection pipe 6, is condensed in the condensation chamber 7, and is finally collected in the inside of the collection chamber 8.
