Detailed implementation manners

[0020] The technical solutions in the present invention will be clearly and completely described below with reference to the accompanying drawings in the present invention. In addition, the forms of the various structures described in the following embodiments are merely illustrative, and the present invention is not limited to the various structures described in the following embodiments. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0021] Refer to Figures 1-4 , the present invention provides a neutralization kettle for preparing epoxy resin, including an outer shell 3. An inner shell 16 is welded inside the outer shell 3. A heating assembly is arranged between the outer shell 3 and the inner shell 16. The top of the inner shell 16 is rotatably connected to a rotating pipe 10 through a bearing. Sliding grooves 19 are opened on both sides of the rotating pipe 10. A scraping frame 15 is slidably connected in the sliding grooves 19. A plurality of auxiliary rods 13 are fixed in the scraping frame 15 by bolts. A plurality of tension springs 18 are fixed between adjacent scraping frames 15 by bolts. A driving assembly is arranged at the top of the inner shell 16. An extrusion assembly for moving the scraping frame 15 to contact the inner wall of the inner shell 16 is arranged at the top of the inner shell 16. Thus, the driving assembly drives the scraping frame 15 and the auxiliary rods 13 to stir the mixture in the inner shell 16. At this time, there is a gap between the initial position of the scraping frame 15 and the inner wall of the inner shell 16, thereby reducing the friction between the scraping frame 15 and the inner shell 16 during rotation. When discharging, the two scraping frames 15 are moved outward by the extrusion assembly to contact the inner wall of the inner shell 16, thereby scraping the adhered materials on the inner wall of the inner shell 16. It is simple and convenient to use and saves resources. A feed pipe 1 is welded to the top of the inner shell 16. A discharge pipe 7 is welded to the bottom of the inner shell 16, and the bottom end of the discharge pipe 7 passes through the outer shell 3, thereby facilitating feeding and discharging. A plurality of support feet 4 are fixed to the bottom outer wall of the outer shell 3 by bolts, thereby providing auxiliary support for the outer shell 3.

[0022] In the present utility model, the driving assembly includes a first pulley 6, which is key-connected to the circumferential outer wall of the rotating tube 10. A servo motor 12 is fixed to the top of the inner housing 16 by bolts. One end of the output shaft of the servo motor 12 is key-connected to a second pulley 11, and the second pulley 11 is connected to the first pulley 6 by a belt drive. By starting the servo motor 12, the rotation of the servo motor 12 causes the second pulley 11 to drive the first pulley 6 to rotate. The rotation of the first pulley 6 causes the rotating tube 10 to drive the scraping frame 15 to rotate and perform the mixing operation. The belt is a polyurethane synchronous belt, and the tension is adjusted by adjusting the installation position of the servo motor 12.

[0023] In the present utility model, the extrusion assembly includes a pressure rod 9, which is inserted into the rotating tube 10. Grooves that match the conical surface 17 formed at the bottom end of the pressure rod 9 are provided at the ends of the two scraping frames 15. The inclination angle of the conical surface 17 is 15° - 30°, and the depth of the groove is 2 - 5 mm greater than the stroke of the conical surface.

[0024] An installation frame 5 is fixed to the top outer wall of the inner housing 16 by bolts. An electric telescopic rod 8 is fixed to the inside of the installation frame 5 by bolts, and one end of the electric telescopic rod 8 is fixed to the top end of the pressure rod 9. By starting the electric telescopic rod 8, the elongation of the electric telescopic rod 8 drives the pressure rod 9 to move downward along the rotating tube 10 and extrude the grooves provided on the scraping frame 15 through the conical surface 17, so that the scraping frame 15 is forced to move outward along the chute 19 and contact the inner wall of the inner housing 16.

[0025] In the present utility model, the heating assembly includes a heater 14. A heating cavity is formed between the outer housing 3 and the inner housing 16. The heater 14 is fixed to the inside of the outer housing 3 by bolts and inserted into the heating cavity. Water pipes 2 are welded to both sides of the outer housing 3, and the water pipes 2 are communicated with the heating cavity. Water is injected into the heating cavity through the water pipes 2, and then the water is heated by the heater 14, and through heat exchange, the materials inside the inner housing 16 are evenly heated.

[0026] Working principle of the utility model: During use, water is injected into the heating cavity through the water pipe 2, and then the water is heated by the heater 14 and undergoes heat exchange, so that the materials in the inner shell 16 are evenly heated. By starting the servo motor 12, the rotation of the servo motor 12 causes the pulley two 11 to drive the pulley one 6 to rotate. The rotation of the pulley one 6 causes the rotating pipe 10 to drive the scraping frame 15 to rotate and perform the mixing operation. At this time, there is a gap between the initial position of the scraping frame 15 and the inner wall of the inner shell 16, thus reducing the friction between the scraping frame 15 and the inner shell 16 during rotation. When discharging, by starting the electric telescopic rod 8, the elongation of the electric telescopic rod 8 drives the pressing rod 9 to move downward along the rotating pipe 10 and squeeze the groove formed in the scraping frame 15 through the conical surface 17, so that the scraping frame 15 is forced to move outward along the sliding groove 19 and contact the inner wall of the inner shell 16, thereby scraping off the adhering materials on the inner wall of the inner shell 16. It is simple and convenient to use and saves resources.
