[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 This utility model discloses a protective device for a double cone dryer, comprising a base 1, a double cone drying tank 2 on the base 1, a discharge cylinder 3 at the discharge end of the double cone drying tank 2, a transfer cylinder 4 above the discharge cylinder 3, an annular frame 9 rotatably arranged between the discharge cylinder 3 and the transfer cylinder 4, a plurality of scraper plates 11 symmetrically arranged inside the discharge cylinder 3 on the inner ring of the annular frame 9, and the scraper plates 11 contacting the inner wall of the discharge cylinder 3, a toothed ring on the outer ring of the annular frame 9, a motor 7 on one side of the discharge cylinder 3, and a gear 8 meshing with the toothed ring at the output end of the motor 7;

[0023] The upper end of the adapter cylinder 4 is provided with a docking flange 5, and the top of the adapter cylinder 4 is provided with a cover plate 6, which is fixed to the upper end of the docking flange 5 by bolts.

[0024] The motor 7 is a servo motor.

[0025] In this protective device for the double cone dryer, when the double cone dryer 2 needs to discharge material, it is first rotated so that the open end of the discharge cylinder 3 faces downwards. At this time, the operator removes the cover plate 6 on top of the adapter cylinder 4 to allow the material to be discharged smoothly. Next, the motor 7 on one side of the discharge cylinder 3 is started. Since the motor 7 is a servo motor, it can precisely control the speed and rotation angle. The output end of the motor 7 drives the gear 8 to rotate, and the gear 8 meshes with the gear ring on the outer ring of the annular frame 9, thereby causing the annular frame 9 to rotate around the axis between the discharge cylinder 3 and the adapter cylinder 4.

[0026] Multiple scraper blades 11 symmetrically arranged on the inner ring of the annular frame 9 rotate inside the discharge cylinder 3, and the scraper blades 11 always remain in contact with the inner wall of the discharge cylinder 3. During rotation, the scraper blades 11 can scrape off the material adhering to the inner wall of the discharge cylinder 3, ensuring that the material can be discharged smoothly and preventing the material from accumulating on the inner wall of the discharge cylinder 3.

[0027] The adapter cylinder 4 and the discharge cylinder 3 are connected by a support rod 10. The bottom end of the support rod 10 is fixed to the outer wall of the discharge cylinder 3, and the top end of the support rod 10 is fixed to the outer wall of the adapter cylinder 4. The two ends of the support rod 10 are respectively welded to the discharge cylinder 3 and the adapter cylinder 4.

[0028] In terms of structural design, the adapter cylinder 4 and the discharge cylinder 3 are connected by a support rod 10. The two ends of the support rod 10 are welded to the outer walls of the discharge cylinder 3 and the adapter cylinder 4, respectively. This connection method not only makes the assembly of the adapter cylinder 4 more convenient, but also provides stable support for the adapter cylinder 4.

[0029] The lower end of the adapter cylinder 4 and the upper end of the discharge cylinder 3 are both provided with annular grooves 12. The upper and lower ends of the annular frame 9 are both provided with annular protrusions 13 that are inserted into the annular grooves 12 and rotatably connected to the annular grooves 12. A bearing is embedded in the annular groove 12. The outer ring of the bearing is interference-fitted with the inner wall of the annular groove 12, and the inner ring of the bearing is interference-fitted with the outer wall of the annular protrusion 13. This structural design greatly improves the stability of the annular frame 9 when it rotates, ensuring that the scraper 11 can smoothly scrape the material on the inner wall of the discharge cylinder 3.

[0030] Improving equipment operational stability: A servo motor is used as the drive motor, enabling precise control of the rotation speed and angle of the annular frame 9, ensuring the stability and reliability of the scraper plate 11. The annular frame 9, along with the discharge cylinder 3 and the adapter cylinder 4, utilizes annular grooves 12, annular protrusions 13, and bearings to significantly enhance the stability of the annular frame 9 during rotation, preventing the scraper plate 11 from shaking during scraping, ensuring consistent scraping performance, and improving the overall operational stability of the equipment.

[0031] High adaptability: The length of the scraper 11 is not subject to mandatory regulations. The length of the scraper 11 can be flexibly adjusted according to the actual size of the discharge cylinder 3 and the characteristics of the material to meet the scraping requirements under different working conditions, thereby improving the applicability of the protective device.
