Description
Technical Field
[0001] The present application relates to the technical field of metal powder drying, and in particular to a metal powder drying device. Background Art
[0002] Powder metallurgy is a process technology that produces metal powder or uses metal powder as raw material, and then forms and sinters it to manufacture metal materials, composite materials and various types of products. Metal powder often needs to be dried before production and processing to ensure that the metal powder can affect the quality of the finished product during subsequent processing.
[0003] Currently, gold powder is often dried by directly placing it in a drying oven. To improve the drying efficiency of the gold powder, the prior art often uses stirring to evenly dry the powder in the drying oven. However, the stirring blades only have a limited stirring effect on the gold powder in the drying oven, making it difficult to fully dry the gold powder. Utility Model Content
[0004] In view of the technical problems existing in the background technology, the present application provides a metal powder drying device, which can more fully interfere with the polygonatum powder.
[0005] The present invention provides a metal powder drying device, comprising:

[0009] The rotating plate is rotatably arranged on the top of the lifting device, and the rotating plate is in contact with the top of the lifting device.
[0010] In the technical solution of the embodiment of the present application, the metal powder in the storage chamber is heated by a heating device, and then the metal powder is dried. During the process of the heating device heating the metal powder in the storage chamber, the lifting device transports the metal powder at the bottom of the drying box to the top of the drying box. During the rotation process, the rotating plate arranged on the top of the lifting device evenly disperses the metal powder transported to the top of the lifting device around the lifting device, so that the heating device can fully heat and dry the metal powder in the storage chamber.
[0011] In some embodiments, the lifting device comprises:
[0012] A lifting cylinder is placed in the storage chamber, one end of the lifting cylinder is fixedly connected to the bottom end of the drying box, and the other end extends toward the top end of the drying box.

[0014] A rotating shaft, the rotating shaft being placed in the lifting cylinder, one end of the rotating shaft passing through the drying box and connected to the driving motor;
[0015] A spiral blade is arranged on the rotating shaft.
[0016] In this embodiment, the metal powder enters the lifting cylinder through the opening at the bottom end of the lifting cylinder, and the driving motor drives the spiral blade to rotate through the rotating shaft, thereby being able to lift the metal powder at the bottom end of the lifting cylinder to the top end of the lifting cylinder.
[0017] In some embodiments, the rotating plate is disposed on a rotating shaft, and the driving motor drives the rotating plate to rotate via the rotating shaft.
[0018] In this embodiment, the rotating plate is driven to rotate by the rotating shaft, which greatly reduces the complexity of the device and further reduces the production cost of the drying device.
[0019] In some embodiments, a stirring device is further included, wherein the stirring device is disposed on the rotating shaft and is used to stir the metal powder in the storage chamber.
[0020] In this embodiment, by driving the stirring device to rotate and stir the metal powder in the storage chamber, not only can the metal powder in the storage chamber be driven to move in the storage chamber, helping the metal powder preheating device to fully contact and dry the metal powder more evenly; but also during the rotation of the stirring device, the moisture in the metal powder can be caused to dissipate, thereby improving the drying rate and efficiency of the metal powder.
[0021] In some embodiments, the stirring device includes a U-shaped frame and a stirring blade, the stirring blade is provided at both ends of the U-shaped frame, and the stirring blade is connected to the rotating shaft through the U-shaped frame.
[0022] In this embodiment, the driving motor drives the spiral blades to rotate through the rotating shaft and simultaneously drives the U-shaped frame to rotate, which greatly reduces the complexity of the device and further reduces the production cost of the drying device.

[0024] In this embodiment, the metal powder adhering to the side wall of the lifting cylinder can be scraped off by the U-shaped frame, thereby fully heating and drying the metal powder in the storage chamber.
[0025] In some embodiments, flexible scraping teeth are further provided at both ends of the U-shaped frame, and the flexible scraping teeth can extend into the opening.
[0026] In this embodiment, the flexible scrapers at both ends of the U-shaped frame can extend into the opening, which can effectively prevent the opening from being blocked by metal powder.
[0027] In some embodiments, the bottom end of the drying cylinder is in a "funnel" shape.
[0028] In this embodiment, the drying cylinder with a "funnel"-shaped bottom structure can help the metal powder in the storage chamber flow to the opening at the bottom of the lifting cylinder, greatly improving the transfer efficiency of the metal powder.
[0029] In some embodiments, a discharge port is further included, which is disposed at the bottom end of the drying box and is connected to the storage cavity.
[0030] In this embodiment, the metal powder heated and dried in the drying box can be taken out more conveniently through the discharge port provided at the bottom end of the drying box.

[0050] Powder metallurgy is a process technology that produces metal powder or uses metal powder as raw material, and then forms and sinters it to manufacture metal materials, composite materials and various types of products. Metal powder often needs to be dried before production and processing to ensure that the metal powder can affect the quality of the finished product during subsequent processing.
[0051] Currently, when drying gold powder, the gold powder is often placed directly in a drying oven for drying. During the drying process, in order to improve the drying efficiency of the gold powder, the prior art often stirs the powder to ensure uniform drying of the powder in the drying oven. However, the stirring blades have a limited stirring effect on the gold powder in the drying oven 1 and cannot fully dry the gold powder.
[0052] In order to solve the technical problem in the prior art that the stirring blades have a single stirring effect on the gold powder in the drying box and cannot fully dry the gold powder, the present application provides a metal powder drying device, wherein the metal powder at the bottom of the drying box is transported to the upper end of the drying box by a lifting device, and the metal powder at the top of the lifting device is evenly dispersed around the lifting device by a rotating plate, thereby achieving the purpose of improving the drying effect of the heating device on the metal powder.

[0054] Specifically, during use, the metal powder is stored in the storage chamber in the drying box 1, the heating device 3 is started, and the metal powder in the storage chamber is heated by the heating device 3, thereby drying the metal powder. While the heating device 3 is heating the metal powder in the storage chamber, the lifting device 2 transports the metal powder at the bottom of the drying box 1 to the top of the drying box 1, and the rotating plate 4 provided on the top of the lifting device 2 rotates, and the metal powder transported to the top of the lifting device 2 by the lifting device 2 is evenly dispersed around the lifting device 2, so that the heating device 3 can fully heat and dry the metal powder in the storage chamber.
[0055] Furthermore, in the embodiment of the present application, the lifting device 2 includes a lifting cylinder 21, a drive motor 22, a rotating shaft 23, and a spiral blade 24.

[0060] Further, in the embodiments of this application, please refer to Figure 3 Flexible scraping teeth 53 are also provided at both ends of the U-shaped frame 51, and the flexible scraping teeth 53 can extend into the opening. When the driving motor 22 drives the U-shaped frame 51 to rotate through the rotating shaft 23, the flexible scraping teeth 53 at both ends of the U-shaped frame 51 can extend into the opening, which can effectively prevent metal powder from clogging the opening.
[0061] Furthermore, in the embodiment of the present application, the bottom end of the drying cylinder is in a "funnel" shape. The "funnel"-shaped drying cylinder with a bottom structure can help the metal powder in the storage chamber flow to the opening at the bottom of the lifting cylinder 21, thereby greatly improving the transfer efficiency of the metal powder.
[0062] Furthermore, in the embodiment of the present application, a discharge port 6 is also included. The discharge port 6 is arranged at the bottom end of the drying box 1 and is connected to the storage cavity.
