[0027] Embodiment 1:

[0028] A drainage structure for a compressed air dryer, comprising a drainage tank 1 and a water inlet pipe 2. The water inlet pipe 2 is connected to the top of the drainage tank 1, and a filtering mechanism and a crushing mechanism are arranged inside the drainage tank 1.

[0029] The filtering mechanism includes a processing unit and a vibration unit. Both the processing unit and the vibration unit are arranged inside the drainage tank 1. The vibration units are symmetrically distributed on both sides of the filter net 302, thereby improving the vibration efficiency of the device for the filter net 302.

[0030] The vibration unit includes a fixing plate 303, a limiting rod 304, a compression spring 305, a reduction motor 306, a fixing bolt 307, a connecting roller 308 and a pressing member 309. The fixing plate 303 is installed on the inner wall of the drainage tank 1, the limiting rod 304 is installed inside the fixing plate 303, the compression spring 305 is connected to the inside of the fixing plate 303, the reduction motor 306 is arranged on the top of the drainage tank 1, and the reduction motor 306 is fixed to the top of the drainage tank 1 through the fixing bolt 307, which facilitates the disassembly and assembly of the reduction motor 306 and makes its fixation more firm. The fixing bolt 307 is connected to the fixed end of the reduction motor 306, the connecting roller 308 is connected to the rotating end of the reduction motor 306, the pressing member 309 is installed on the outer wall of the connecting roller 308, and the outer end of the pressing member 309 abuts against the side of the filter net 302. Thus, the filter net 302 can be continuously vibrated by the rotation of the pressing member 309, and the material of the pressing member 309 is an elastic material, and the elastic material can effectively protect the filter net 302.

[0031] Embodiment 2:

[0032] Based on Embodiment 1: The processing unit includes a supporting seat 301 and a filter net 302. The supporting seat 301 is installed inside the drainage tank 1, and the filter net 302 is arranged inside the drainage tank 1.

[0033] The crushing mechanism includes a driving motor 401, a mounting roller 402, a rotating gear 403, a partition plate 404, a rotating rod 405, a transmission gear 406 and a cutter head 407. The driving motor 401 is installed on the top of the drainage tank 1, the mounting roller 402 is connected to the rotating end of the driving motor 401, the rotating gear 403 is installed on the outer wall of the mounting roller 402, and the rotating gear 403 meshes with the transmission gear 406. Through the rotation of the rotating gear 403 and the connection of the transmission gear 406, the rotating rod 405 can rotate synchronously. The partition plate 404 is installed inside the drainage tank 1, the rotating rod 405 is connected to the inside of the partition plate 404, and the rotating rod 405 is rotatably connected to the inside of the partition plate 404. Furthermore, the cutter head 407 can be driven to rotate rapidly, thereby being able to crush sundries and improving the collection and treatment efficiency of the liquid. The transmission gear 406 is installed on the outer wall of the rotating rod 405, and the cutter head 407 is installed on the outer wall of the rotating rod 405.

[0034] Embodiment 3: The filter screen 302 passes through the limit rod 304 and is connected to one end of the compression spring 305, thereby limiting the filter screen 302 to make the filtration of impurities more stable. The abutment 301 is distributed directly below the water inlet pipe 2. The abutment 301 can reduce the pressure generated by the falling of the collected liquid and plays a certain protective role.

[0035] During use, the liquid is discharged into the drainage tank 1 through the water inlet pipe 2. The abutment 301 can reduce the pressure generated by the falling of the liquid. The liquid can be preliminarily filtered through the filter screen 302. After long-term use, the operation of the reduction motor 306 drives the connecting roller 308 to rotate, thereby driving the abutting member 309 to continuously strike and vibrate the filter screen 302. Under the limitation of the limit rod 304 and the compression spring 305, it can prevent the sundries in the liquid from blocking the filter holes and improve the filtration efficiency. The operation of the driving motor 401 makes the mounting roller 402 rotate, and then drives the rotating gear 403 to rotate. Since the rotating gear 403 meshes with the transmission gear 406, the rotation of the rotating gear 403, under the connection of the transmission gear 406, enables the rotating rod 405 to rotate synchronously, and then can drive the cutter head 407 to rotate rapidly, thereby being able to crush the sundries and improving the collection and treatment efficiency of the liquid.
