This utility model facilitates the rapid drying of metal powder by grading, and can quickly collect the remaining powder after drying.

[0004] The aforementioned patent uses high-temperature air to raise the temperature inside the tower and thus dry the metal powder. However, the metal powder drying tower cannot perform cyclic drying, resulting in different degrees of drying of the powder in different parts of the tower. This can easily lead to local over-drying or under-drying, affecting the consistency and stability of the powder. Therefore, there is a need for a metal powder drying tower that can perform cyclic drying of metal powder. Utility Model Content

[0022] Preferably, a support ring is fixedly connected to one end of the reinforcing plate.

[0023] The effect achieved by the above components is that the reinforcing plate moves and rotates around the support ring.

[0024] In summary, the beneficial effects of this utility model are as follows:

[0025] In this invention, when the metal powder needs to be circulated and dried, the output end of the servo motor rotates in reverse through the rotating device, so that the metal powder input guide pipe is discharged from the outlet. The rotating device solves the problem that traditional metal powder drying towers cannot perform circulated drying, resulting in different degrees of drying of powder in different parts of the drying tower, which easily leads to local over-drying or local under-drying.

[0026] In this invention, a cleaning device is used to prevent metal powder from adhering to the inner wall of the tower. The rotating rod rotates, causing the ring to rotate, which in turn causes the connecting plate to move the scraper, thus scraping the metal powder off the inner wall of the tower. This cleaning device solves the problem that traditional metal powder drying towers cannot prevent some metal powder from adhering to the inner wall of the drying tower during the drying process.

A servo motor 202 is fixedly connected to one side of the fixed frame 201. A rotating rod 203 is fixedly connected to the output end of the servo motor 202. A conveying blade 204 is fixedly connected to one end of the rotating rod 203. A guide pipe 206 is sleeved on the outside of the conveying blade 204. Three discharge ports 207 are opened on the arc surface of the guide pipe 206. A support frame 205 is fixedly connected to the arc surface of the guide pipe 206. Three ends of the support frame 205 are fixedly connected to the tower body 1. A discharge cover 208 is rotatably connected to the arc surface of the conveying blade 204. One end of the discharge cover 208 is fixedly connected to the tower body 1. A rubber plug 209 is interference-fitted inside the discharge cover 208. This achieves the effect of the servo motor 202 starting output end driving the rotating rod 203 to rotate, thus causing the conveying blade 204 to rotate. A flange bearing 213 is fixedly connected to the arc surface of the rotating rod 203, and the arc surface of the flange bearing 213 is fixedly connected to the tower body 1. This achieves the effect of preventing the rotating rod 203 from deforming during rotation. A fixing plate 212 is fixedly connected to one side of the discharge hood 208, and a ball bearing 211 is fixedly connected to one side of the fixing plate 212. This achieves the effect of fixing the ball bearing 211 to the fixing plate 212, and fixing the fixing plate 212 to the discharge hood 208. A circular block 210 is fixedly connected to the inner side of the ball bearing 211, and one end of the circular block 210 is fixedly connected to the conveying auger 204. This achieves the effect of the conveying auger 204 rotating to drive the circular block 210 to rotate within the ball bearing 211.

[0035] Reference Figure 4As shown in this embodiment: the cleaning device 3 includes a ring 31, the inner side of which is fixedly connected to a rotating rod 203, and a connecting plate 32 is fixedly connected to the arc surface of the ring 31.

[0036] Working principle: When it is necessary to circulate and dry metal powder, the operator first adds the metal powder to be dried into the tower body 1 through the feed inlet 4. The tower body 1 then dries the powder. The servo motor 202 is then started, causing its output to rotate in the reverse direction, which drives the rotating rod 203. The rotating rod 203 drives the conveying auger 204 to rotate, which in turn feeds the metal powder into the guide pipe 206 and then discharges it through the outlet 207, thus completing the circulating drying of the metal powder. After the metal powder is dried, the rubber stopper 209 is pulled to remove the obstruction of the discharge hood 208. The servo motor 202 is then controlled to rotate in the forward direction, causing the metal powder to enter the discharge hood 208 and be discharged from the tower body 1. The rotating device 2 solves the problem of traditional metal powder drying towers, which cannot circulate and dry, resulting in different drying degrees of powder in different parts of the tower, and easily leading to local over-drying or local under-drying.

[0037] By using the cleaning device 3, when it is necessary to prevent metal powder from adhering to the inner wall of the tower body 1, the rotating rod 203 rotates, causing the ring 31 to rotate, which in turn causes the connecting plate 32 to move the scraper 33. During the movement, the scraper 33 scrapes off the metal powder adhering to the inner wall of the tower body 1, thus removing the metal powder from the inner wall of the tower. By using the cleaning device 3, the problem of traditional metal powder drying towers being unable to prevent some metal powder from adhering to the inner wall of the drying tower during the drying process is solved.
