[0028] Embodiment 1
[0029] AsFigures 1-4 As shown in the figure, a reaction kettle for polar molecules and unsaturated polyester resin proposed by the present utility model includes a kettle body 1. A feed inlet is fixedly installed at the top of the kettle body 1 for adding materials. A cover plate is hinged on the feed inlet. A discharge pipe is fixed at the bottom of the kettle body 1, and a valve is installed on the discharge pipe. The valve can be opened to discharge materials. A rotating shaft 3 is rotatably installed in the kettle body 1. A motor 2 is fixedly installed at the top of the kettle body 1. The output shaft of the motor 2 is in transmission connection with the rotating shaft 3. The motor 2 drives the rotating shaft 3 to rotate. A stirrer 4 is fixed on the rotating shaft 3. The rotation of the rotating shaft 3 drives the stirrer 4 to mix the materials.
[0030] Two cross bars 5 are fixed on one side of the rotating shaft 3. A scraping blade 6 in contact with the inner wall of the kettle body 1 is fixed between one ends of the two cross bars 5. During the rotation of the rotating shaft 3, the cross bars 5 are driven to rotate around the axis of the rotating shaft 3, and the scraping blade 6 moves in a circular motion to scrape the materials adhered to the inner wall of the kettle body 1.
[0031] Embodiment 2
[0032] As Figures 1-4 shown, based on Embodiment 1, a conveying mechanism for conveying the materials scraped by the scraping blade 6 to the stirrer 4 is provided on the scraping blade 6. The conveying mechanism includes a vertical shaft 8 rotatably installed between the two cross bars 5. Two rollers 9 in rolling connection with the inner wall of the kettle body 1 are fixed at both ends of the vertical shaft 8. The rotation of the cross bars 5 drives the rollers 9 to roll in the kettle body 1, so that the vertical shaft 8 rotates without additional power drive. A plurality of conveying cylinders 7 are fixed on one side of the scraping blade 6. A conveying auger 11 is rotatably installed in the conveying cylinder 7. The vertical shaft 8 rotates through the conveying cylinder 7 and is in transmission connection with the conveying auger 11. A branch pipe 10 communicating with the inside of the conveying cylinder 7 is fixed on the curved surface of the conveying cylinder 7.
[0033] Among them, one end of the conveying cylinder 7 is open, and the other end is sealed. A partition plate 12 is fixed in the conveying cylinder 7. The conveying auger 11 is located in one end of the conveying cylinder 7, and the vertical shaft 8 is located in the other end of the conveying cylinder 7. The conveying auger 11 and the vertical shaft 8 are located on both sides of the partition plate 12. The connection position of the branch pipe 10 and the conveying cylinder 7 is located on the side of the partition plate 12 away from the vertical shaft 8.
[0034] In addition, a connecting shaft 13 fixed to the conveying auger 11 is rotatably installed on the partition plate 12. A first bevel gear 14 located in the conveying cylinder 7 is fixedly sleeved on the vertical shaft 8. A second bevel gear 15 meshing with the first bevel gear 14 is fixed on the connecting shaft 13. The rollers 9 roll in the kettle body 1, so that the vertical shaft 8 rotates, driving the first bevel gear 14 to rotate. The second bevel gear 15 rotates accordingly, causing the connecting shaft and the conveying auger 11 to rotate to guide the scraped materials to be discharged from the branch pipe 10 through the conveying cylinder 7 and conveyed to the vicinity of the stirrer 4 for stirring, so as to realize the conveying of the scraped materials and make the materials adhered to the inner wall of the kettle body 1 be fully stirred and mixed.
[0035] It should be noted that the inner diameter of the conveying cylinder 7 is larger than that of the branch pipe 10, so that the material flowing into the branch pipe 10 from the conveying cylinder 7 has a greater pressure, enabling the material ejected from the branch pipe 10 to travel farther, thereby ensuring that the material contacts the stirrer 4 and is fully stirred.
[0036] Working principle: The motor 2 drives the rotation of the rotating shaft 3, and the stirrer 4 rotates accordingly to stir and mix the material. During the rotation of the rotating shaft 3, the cross bar 5 is driven to rotate around the axis of the rotating shaft 3, driving the scraping blade 6 to perform a circular motion to scrape the material adhering to the inner wall of the kettle body 1; while the scraping blade 6 performs a circular motion, the roller 9 is driven to roll in the kettle body 1, causing the vertical shaft 8 to rotate, driving the first bevel gear 14 to rotate, and the second bevel gear 15 rotates accordingly to drive the connecting shaft and the conveying auger 11 to rotate, guiding the scraped material to be discharged from the branch pipe 10 through the conveying cylinder 7 and conveyed to the vicinity of the stirrer 4 for stirring, thereby realizing the conveying of the scraped material, enabling the material adhering to the inner wall of the kettle body 1 to be fully stirred and mixed, and improving the reaction efficiency.
[0037] The above specific embodiments are only several optional embodiments of the present invention. Based on the technical solution of the present invention and the relevant revelations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
