[0001] The utility model relates to the technical field of three-pass drying machines, in particular to a detachable three-pass drying machine. Background Art

[0002] The three-pass dryer is a highly efficient and energy-saving drying equipment. Its core feature is that it has three layers of thermal insulation and a circulating self-insulating structure. This design effectively improves thermal efficiency and reduces heat loss.

[0003] In the prior art, the driving structure drives the gear ring and the roller ring to rotate, so that the dryer cylinder rotates. The existing gear ring and the roller ring are connected to the dryer cylinder through a support frame, and the support frame is connected to the dryer cylinder by welding. The dryer cylinder will produce a small amplitude vibration when rotating. The support frame is easily deformed under the influence of long-term vibration, which further affects the use effect of the gear ring or the roller ring. Since the support frame is connected to the dryer cylinder by welding, it will make it difficult to replace the deformed support frame later.

[0004] Therefore, in order to solve the above problems, a detachable three-pass drying machine is provided. Utility Model Content

A connecting assembly 503 is arranged, and a support frame 501 is installed on the inner surface of the gear ring 6 and the roller ring 7. The connecting assembly 503 includes a threaded rod 50301, and a mounting block 50302 is arranged on the upper end of the threaded rod 50301. The threaded rod 50301 is installed inside the threaded hole, and a mounting groove 50303 is opened on the upper surface of the mounting block 50302. One end of the mounting groove 50303 extends to the inside of the threaded rod 50301, and a spring 50304 is installed on the inner bottom of the mounting groove 50303. A connecting block 50305 is installed on the other end of the spring 50304, and both ends of the connecting block 50305 are hinged with connecting plates 50306;

[0027] The connection ring 502 and the connection assembly 503 are used in combination to replace the welding method of the support frame 501 and the dryer cylinder 3 in the prior art;

[0028] A guide groove 50307 is formed on the inner surface of the installation groove 50303, and a limit rod 50308 is formed on the outer surface of the connecting plate 50306. The limit rod 50308 is slidably connected to the inside of the guide groove 50307.

[0029] The guide groove 50307 and the limiting rod 50308 are used in conjunction with each other to limit the position of the connecting plate 50306, thereby preventing the connecting plate 50306 from being separated from the inside of the installation groove 50303 during use.

[0030] A telescopic rod 50309 is installed at the inner bottom of the installation groove 50303, a spring 50304 is sleeved on the outer surface of the telescopic rod 50309, and a connecting block 50305 is installed on the upper surface of the telescopic rod 50309;

At the same time, the connecting rod 801 cancels the limit of the connecting block 50305, so that the spring 50304 gradually recovers its elasticity and pushes the connecting block 50305 to move upward in the installation groove 50303, and the telescopic rod 50309 is gradually stretched. At the same time, the limit rod 50308 moves outward along the guide groove 50307, ​​so that the connecting plate 50306 moves outward in the installation groove 50303. Extend it out, then press the connecting plate 50306 with your fingers and rotate the connecting plate 50306, so that the threaded rod 50301 is screwed out from the inside of the threaded hole, thereby canceling the fixed installation of the connecting ring 502 with the dryer cylinder 3, and thus facilitating the removal of the support frame 501 from the dryer cylinder 3 and replacing it. Through the coordinated use of the connecting block 50305, the connecting plate 50306 and the spring 50304, the threaded rod 50301 can be rotated from the threaded hole without the aid of external tools, and it is convenient to disassemble.
