[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] See also Figure 1-Figure 3 The utility model provides a technical solution: a single-drum rotary dryer, comprising a rotating drum 1, a steel ring 2, a lower hopper 3, a roller 4, a motor 5, a support plate 6, an elevator 1 601, a fixed head 602, a connecting rod 603, a screw 604, a support head 605, an elevator 2 606 and a gear ring 7. The steel ring 2 is installed on the left and right sides of the rotating drum 1, and the lower hopper 3 is provided on the left side of the rotating drum 1. The bottom of the steel ring 2 is connected to the top of the roller 4. The motor 5 is installed in the middle position of the support plate 6, and the gear installed on the rotating shaft of the motor 5 is meshed with the gear ring 7. The elevator 1 601 and the elevator 2 606 are provided on the left and right sides of the motor 5. A connecting rod 603 is installed on one side of the elevator 1 601 and the elevator 2 606. The top of the connecting rod 603 is connected to the bottom of the screw 604. The top of the screw 604 is provided with a supporting head 605, and the bottom of the connecting rod 603 is connected and fixed to the fixed head 602.

[0020] As the first embodiment of the utility model: the top of the elevator 1 601 and the elevator 2 606 is provided with a support head 605 corresponding to the bottom of the drum 1. Through this design, the drum 1 can be raised to a certain height under the action of the elevator 1 601 and the elevator 2 606, which is convenient for the disassembly of the motor 5 and the roller 4, and the top of the support block is provided with a rubber pad. Through this design, it plays an anti-slip role to prevent self-rotation when the drum 1 is raised. The fixed head 602 is welded and fixed on the top of the support plate 6. Through this design, the fixed head 602 is prevented from being separated from the support plate 6 during use. The fixed head 602 is connected and fixed by a limit column corresponding to the limit hole opened on the left side of the bottom of the connecting rod 603. Through this design, the connecting rod 603 can be laid down to prevent affecting the operation of the drum 1. The top of the connecting rod 603 is provided with a thread, and the height of the internal thread is equal to the height of the screw 604. Through this design, the screw 604 can be shortened and elongated, and plays a role in supporting the drum 1 when the drum 1 is raised. The bottom of the support head 605 is connected to the top of the screw 604 by welding, and this design plays a role in fixing the support head 605, and a rubber anti-skid pad is provided inside the support head 605, and this design plays a role in preventing slipping when supporting the drum 1. The bottom of the elevator 1 601 and the elevator 2 606 are fixed to the top of the support plate 6 by bolts, and this design plays a role in fixing the elevator 1 601 and the elevator 2 606 to prevent displacement during use. A limit plate is provided around the inside of the lower hopper 3, and a filter screen is placed on the top of the limit plate, and this design facilitates the removal of the filter screen.

[0021] As a second embodiment of the utility model: in this device, due to the installation of the elevator 1 601 and the elevator 2 606 on the top of the support plate 6, the rotating drum 1 can be raised to a certain height, and the motor 5 and the roller 4 are easy to replace and repair. When the elevator 1 601 and the elevator 2 606 lift the rotating drum 1, a rubber pad is provided inside the support block connected through the top to play an anti-slip role and prevent the rotating drum 1 from rotating. When the elevator 1 601 and the elevator 2 606 raise the rotating drum 1 to a certain height, the screw 604 is extended to a certain length at the top of the connecting rod 603 to support the rotating drum 1. The connecting rod 603 can be laid down on the top of the support plate 6 under the action of the fixed head 602 to prevent the rotating drum 1 from being affected. The elevator 1 601 and the elevator 2 606 lower the drum 1 to a certain distance, and connect with the support head 605 on the top of the screw 604, so that the screw 604 can support the drum 1 under the action of the connecting rod 603. Since the drum 1 applies a downward pressure to the support head 605 installed on the top of the screw 604, the connecting rod 603 will not swing back and forth, which can protect the maintenance personnel when disassembling the motor 5 and the roller 4. This design can raise the drum 1 to a certain height under the action of the elevator 1 601 and the elevator 2 606, and connect the support head 605 installed on the top of the screw 604 to the bottom of the drum 1, so that the maintenance personnel can easily perform maintenance work on the motor 5 and the roller 4.
