[0024] The stirring and cleaning assembly 8 includes a fan blade disk 84, the bottom end of the fan blade disk 84 is assembled and connected to the output end of the rotating motor 6, a stirring rod 81 is vertically arranged in the middle of the fan blade disk 84, a plurality of stirring mechanisms 82 are arranged on the stirring rod 81, and a cleaning mechanism 83 is symmetrically arranged on the upper part of the stirring rod 81 above the stirring mechanism 82.

[0025] Among them, the stirring mechanism 82 includes a connecting rod 821, one end of the connecting rod 821 is fixedly connected to the stirring rod 81, and the other end of the connecting rod 821 away from the stirring rod 81 is provided with a stirring blade 822, and the other side surface of the stirring blade 822 away from the connecting rod 821 is in contact with the inner wall of the drying chamber of the drying tower 1. The stirring blade 822 cooperates with the rotation of the stirring rod 81 to break up and stir the materials blown up by the wind. At the same time, the stirring blade 822 contacts the inner wall of the air supply area, and can hang down the materials stuck on its inner wall when rotating, thereby realizing the effect of self-cleaning.

[0026] In addition, the cleaning mechanism 83 includes a connecting plate 831, which is symmetrically fixed on the top of the rod body of the stirring rod 81. A scraper 832 is arranged on the surface of one side of the connecting plate 831 close to the inner wall of the drying chamber of the drying tower 1. The scraper 832 is made of a rubber material, and the scraper 832 is in contact with the inner wall of the drying chamber of the drying tower 1. The connecting plate 831 can also play a certain stirring and breaking role in conjunction with the rotation of the stirring rod 81. The scraper 832 contacts the inner wall of the drying tower 1. When rotating, the scraper 832 can hang down most of the materials stuck to the inner wall.

[0027] Moreover, an air supply component 3 is connected to the other end of the air supply duct 2 away from the air inlet of the drying tower 1. The air supply component 3 can generate hot air and send it into the drying tower 1 for drying. The other end of the feeding duct 5 away from the feeding port of the drying tower 1 is connected to a screw feeder 4. The screw feeder 4 can send the wet material into the drying tower 1 for drying. The screw feeder 4 and the air supply component 3 are both current technologies and are technical means well known to people in the field of flash dryers. There is no need to elaborate on their structure and operation.

[0028] In the present embodiment, when the flash dryer is drying the wet material, the wet material is fed into the drying chamber of the drying tower 1 by the screw feeder 4 in cooperation with the feeding pipe 5, and then the air supply component 3 cooperates with the air supply pipe 2 to feed the hot air into the drying chamber of the drying tower 1, and then after the rotating motor 6 is driven, the output end of the rotating motor 6 drives the fan disc 84 to rotate, thereby driving the stirring rod 81 to rotate.

[0029] When the stirring rod 81 rotates, the multiple stirring mechanisms 82 on the rod body will break up and stir the materials fed in, and the stirring blades 822 on one side can not only stir and break up the materials, but also scrape off the materials stuck on the inner wall to perform self-cleaning of the inner wall.

[0030] When the stirring rod 81 rotates, the cleaning mechanism 83 at the top, and its longer connecting plate 831, can cause the scraper 832 to scrape off most of the material adhering to the inner wall, thereby preventing the material from adhering to the inner wall, so that the material can be sent to the discharge pipe 7 to be extracted. The scraper 832 is made of a material including but not limited to nitrile rubber, so that the scraper 832 has better wear resistance and flexibility.

[0031] In the utility model, by setting up the stirring and cleaning component 8, when the drying tower 1 dries the material, the rotating motor 6 drives the stirring rod 81 to rotate, so that the stirring blade 822 of the stirring mechanism 82 can not only stir and break up the material, but also scrape off the material stuck to the inner wall to perform self-cleaning of the inner wall, and the scraper 832 of the cleaning mechanism 83 above can also hang down most of the material on the inner wall, so that the drying tower 1 does not need to be cleaned frequently, and the stirring and cleaning component 8 achieves the effect that the inner wall of the drying tower 1 can be self-cleaned, thereby improving the cleaning efficiency.
