[0052] 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.

[0053] Example 1:

[0054] like Figures 1 to 7 As shown, this utility model provides a dryer cover structure, including: a granulation dryer 1 and a sealing cover 2 movably installed on the granulation dryer 1 for sealing the material inlet of the granulation dryer 1.

[0055] In order to improve the sealing performance between the granulator dryer 1 and the sealing cover plate 2 and prevent material or gas leakage during the operation of the granulator dryer 1, a sealing structure for increasing the sealing performance between the sealing cover plate 2 and the granulator dryer 1 is arranged on the sealing cover plate 2, and an installation structure for installing the sealing cover plate 2 on the granulator dryer 1 is arranged on the granulator dryer 1 and the sealing cover plate 2.

[0056] The sealing structure includes a connecting ring 3 movably mounted on the inner wall of the sealing cover plate 2, a threaded ring 301 threaded inside the sealing cover plate 2, threads adapted to the threaded ring 301 on the inner wall of the sealing cover plate 2, the threaded ring 301 on the outer surface of the connecting ring 3, and a U-shaped sealing ring 302 movably mounted on the granulation dryer 1. The U-shaped sealing ring 302 is fitted onto the connecting ring 3 and is a reinforcing component arranged on the connecting ring 3 to improve the stability of the connecting ring 3. When the sealing cover plate 2 is lowered, it can press the U-shaped sealing ring 302 tightly onto the opening of the granulation dryer 1. The U-shaped sealing ring 302 adopts a U-shaped design, which can wrap around the opening of the granulation dryer 1, thereby improving the sealing performance.

[0057] Specifically, the reinforcing components include a positioning ring 303 arranged on one side of the connecting ring 3, a limiting bolt 304 movably installed on the inner wall of the positioning ring 303, and a threaded groove 305 opened on the inner wall of the sealing cover plate 2. One end of the limiting bolt 304 is threaded into the threaded groove 305. By using a screwdriver to rotate the limiting bolt 304 and unscrew it from the threaded groove 305, the limiting bolt 304 is simultaneously pulled out from the positioning ring 303, thus releasing the restriction on the positioning ring 303. Then, the connecting ring 3 is rotated to unscrew it from the inner wall of the sealing cover plate 2, so that the connecting ring 3 drives the U-shaped sealing ring 302 to move out of the sealing cover plate 2, thereby achieving quick disassembly of the U-shaped sealing ring 302.

[0058] The installation structure includes a threaded mounting ring 4 fitted onto the granulator dryer 1 and a threaded ring 401 arranged on the inner wall of the sealing cover plate 2. The threaded ring 401 is threaded onto the threaded mounting ring 4. After aligning the threaded ring 401 with the threaded mounting ring 4, the sealing cover plate 2 drives the threaded ring 401 to be screwed onto the threaded mounting ring 4. During the process, the sealing cover plate 2 can be lowered and the U-shaped sealing ring 302 can be pressed against the opening of the granulator dryer 1.

[0059] Example 2:

[0060] Based on Example 1, in order to make the sealing structure fit more tightly with the granulation dryer 1 and further improve the sealing effect of the granulation dryer 1, a bonding structure for making the sealing structure fit tightly with the granulation dryer 1 is arranged on the inner wall of the sealing cover plate 2. The bonding structure includes a compression structure for compressing the sealing structure and an adjustment structure for adjusting the compression force of the compression structure.

[0061] The extrusion structure includes a rubber abutment ring 5 arranged on the U-shaped sealing ring 302, a sliding ring 501 vertically slidably installed on the inner wall of the sealing cover plate 2, and an extrusion protrusion ring 502 arranged on the inner wall of the sliding ring 501. The extrusion protrusion ring 502 corresponds to the rubber abutment ring 5. During the movement of the sliding ring 501, it can drive the extrusion protrusion ring 502 to press against the rubber abutment ring 5. The rubber abutment ring 5, when compressed, will press the U-shaped sealing ring 302 onto the outer surface of the granulation dryer 1.

[0062] The adjustment structure includes an adjusting screw 503 threaded onto the inner wall of the sealing cover plate 2, an adjusting gear 504 arranged at one end of the adjusting screw 503, a linkage gear ring 505 rotatably mounted above the sealing cover plate 2 for transmission, the linkage gear ring 505 meshing with the adjusting gear 504, and a limiting component arranged on the linkage gear ring 505 to limit the rotation position of the linkage gear ring 505. One end of the adjusting screw 503 is rotatably mounted on a sliding ring 501. The rotating linkage gear ring 505 can drive the adjusting screw 503 to rotate by meshing with the adjusting gear 504. While the adjusting screw 503 rotates, it can move vertically by threaded engagement with the inner wall of the sealing cover plate 2.

[0063] Specifically, the limiting assembly includes a limiting ring 506 rotatably mounted on the inner wall of the linkage gear ring 505, and a limiting shaft 507 rotatably mounted on the inner wall of the adjusting screw 503. The limiting ring 506 is arranged above the sealing cover plate 2, and the limiting shaft 507 is arranged on the sliding ring 501. The rotating linkage gear ring 505 will rotate on the limiting ring 506, thereby preventing the linkage gear ring 505 from shifting or loosening. The rotating adjusting screw 503 can rotate on the limiting shaft 507.

[0064] Working principle:

[0065] When sealing the granulator dryer 1, the sealing cover plate 2 is placed on the granulator dryer 1 and the U-shaped sealing ring 302 is placed on the opening of the granulator dryer 1. Simultaneously, the threaded ring 401 is aligned with the threaded mounting ring 4 and rotated, causing the sealing cover plate 2 to screw the threaded ring 401 onto the threaded mounting ring 4. During this process, the sealing cover plate 2 descends and presses the U-shaped sealing ring 302 tightly onto the opening of the granulator dryer 1. The U-shaped sealing ring 302, with its U-shaped design, can wrap around the opening of the granulator dryer 1, thereby improving the sealing performance. After fixing the position of the threaded mounting ring 4, the linkage gear ring 505 can be rotated. The rotating linkage gear ring 505 will... The limiting ring 506 rotates, thus preventing the linkage ring 505 from shifting or loosening. The continuously rotating linkage ring 505 can drive the adjusting screw 503 to rotate through meshing with the adjusting gear 504. The rotating adjusting screw 503 can then rotate on the limiting shaft 507. While rotating, the adjusting screw 503 can move vertically through the threaded engagement with the inner wall of the sealing cover plate 2. When the adjusting screw 503 moves vertically, it will drive the adjusting gear 504 to move vertically. During this process, the adjusting gear 504 will not disengage from the linkage ring 505, thus not affecting the normal movement of the adjusting screw 503, thereby enabling the vertical movement of the adjusting screw. The screw 503, through its cooperation with the limiting shaft 507, drives the sliding ring 501 to slide on the inner wall of the sealing cover plate 2. This causes the sliding ring 501 to drive the extrusion protrusion ring 502 to press against the rubber abutment ring 5. The rubber abutment ring 5, under pressure, presses the U-shaped sealing ring 302 against the outer surface of the granulator dryer 1, making the U-shaped sealing ring 302 fit more tightly against the granulator dryer 1, thereby improving the sealing effect. If the sealing effect of the U-shaped sealing ring 302 decreases, the sealing cover plate 2 can be removed, and then the limiting bolt 304 can be rotated with a screwdriver to unscrew the limiting bolt 304 from the threaded groove 305, and at the same time, the limiting bolt 304 can be removed from the positioning ring 303. Pull it out, and the restriction on the positioning ring 303 will be released. Then rotate the connecting ring 3. The connecting ring 3 can drive the positioning ring 303 to rotate. At the same time, the connecting ring 3 can drive the threaded ring 301 to be unscrewed from the inner wall of the sealing cover plate 2, so that the connecting ring 3 can drive the U-shaped sealing ring 302 to be removed from the sealing cover plate 2, realizing the quick disassembly of the U-shaped sealing ring 302. During installation, the connecting ring 3 with the U-shaped sealing ring 302 is screwed back into the sealing cover plate 2 for fixation. Then, the limit bolt 304 is passed through the positioning ring 303 and screwed into the corresponding threaded groove 305, which can prevent the connecting ring 3 from rotating and loosening from the positioning ring 303, and improve the stability of the connecting ring 3.
