Description

Technical Field

[0001] This utility model relates to the field of processing technology for neodecanoic acid glycidyl ester, specifically a stirring device for preparing neodecanoic acid glycidyl ester. Background Technology

[0002] Neodecanoic acid glycidyl ester is produced by the reaction of neodecanoic acid and glycidyl ester. It has a wide range of applications, including as an epoxy resin reactive diluent, for adjusting the acid value of alkyd resins, as a coil coating, for low-temperature baking paint, and for preparing high-solids acrylic resins and paints. A stirring device is used to mix the liquid raw materials during the preparation of neodecanoic acid glycidyl ester.

[0003] However, to prevent the raw materials from sticking to the inside of the mixing device during the mixing process, there is a patent document with publication number CN218590534U, which uses a mixing plate that can rotate and scrape the material after the motor is started, thereby further preventing the glycerides from solidifying on the inner wall of the mixing vessel.

[0004] Based on the above-disclosed technical content, theoretically, the implementation of the relevant technical structure is beneficial for preventing the raw materials inside the stirring device from adhering to the wall. The preparation of glycidyl decanoate also requires mixing by a stirring device. However, the raw materials for preparing glycidyl decanoate will produce certain particulate matter after stirring. When the prepared glycidyl decanoate is discharged from the inside of the stirring device, the particulate matter inside the stirring device will be discharged from the inside of the stirring device along with the glycidyl decanoate. The presence of this particulate matter will affect the preparation quality of glycidyl decanoate. Utility Model Content

[0030] Working principle: In use, firstly, the raw material for preparing glycidyl decanoate is added into the tank 1 through the feed pipe 2. Then, the power to the rotary motor 21 is turned on. After the rotary motor 21 is turned on, it drives the installation rod 18 to rotate through the connection between the rotating shaft 20 and the upright rod 19. Simultaneously, the rotation of the installation rod 18 drives the scraper 3 to rotate through the fastening bolt 17, ensuring thorough mixing of the raw material for preparing glycidyl decanoate. The resulting particles fall from the discharge pipe 30 into the connecting pipe 4. The particles inside the connecting pipe 4 fall onto the filter plate 5. Then, after the preparation of glycidyl decanoate is complete, the control valve of the liquid outlet pipe 6 is opened, discharging the filtered liquid from the connecting pipe 4 through the liquid outlet pipe 6. The particles fall onto the filter plate 5, and the impurities on the filter plate 5 are cleaned regularly. Due to the threaded connection between the nut 10 and the threaded rod 9, the nut 10 can be rotatably removed from the threaded rod 9. Then, the threaded rod 9 is pulled out from the inside of the upper end plate 14, which separates the discharge pipe 30 from the connecting pipe 4, allowing the particles on the filter plate 5 to be poured out. Due to the threaded connection between the cover 7 and the connecting pipe 4, the cover 7 can be rotatably removed from the lower end of the connecting pipe 4, allowing the inside of the connecting pipe 4 to be cleaned. Finally, when it is necessary to clean the inside of the tank 1, the power of the electric push rod 29 is turned on, and the extension of the output shaft inside the electric push rod 29 is used to separate the tank cover 12 from the tank 1, so that the inside of the tank 1 can be cleaned.
