Two sets of fixing rings 302 are fixedly sleeved on the surface of the transmission rod 303 in the inner cavity 101, and a plurality of connecting plates 301 are fixedly connected to the surfaces of the two sets of fixing rings 302. A scraper 300 is fixedly installed at one end of the two sets of connecting plates 301 in the same horizontal line. A feed pipe 103 is connected to the top of the drying cylinder 101, and a baffle 105 is slidably connected to the discharge port 109 of the drying cylinder 101. A handle 106 is fixedly installed on the surface of the baffle 105, and a storage component for storing metal powder is installed in the inner cavity of the base 100.

[0027] The drive motor 102 is started to drive the transmission rod 303 to rotate, and then drives the scraper 300 to continuously rotate along the inner wall of the drying cylinder 101. During the rotation, the scraper 300 continuously lifts the metal powder upward, so that the metal powder is fully mixed with the heat medium in the drying cylinder 101, so that the metal powder is dried by the heat medium. In the process of the scraper 300 continuously lifting the metal powder, the scraper 300 continuously beats the metal powder to prevent the metal powder from becoming compacted.

[0028] See attached Figure 3 , 4 As shown, the storage assembly includes a collection box 405 arranged in the inner cavity of the base 100, one side of the collection box 405 slides through the surface of the base 100, and a handle 406 is fixedly installed on one side surface of the collection box 405. When the baffle 105 is pulled outward, the metal powder directly falls into the collection box 405, so that the metal powder can be collected.

[0029] A winding rod 401 is rotatably connected between the inner walls on both sides of the collecting box 405, and a high-temperature resistant cloth layer 403 is wound on the surface of the winding rod 401. The high-temperature resistant cloth layer 403 is one or a combination of Teflon-coated glass fiber cloth, glass fiber cloth, and polytetrafluoroethylene cloth. One end of the high-temperature resistant cloth layer 403 is fixedly connected to a pull rod 402, and the pull rod 402 is slidably connected to the inner cavity of the collecting box 405. One end of the winding rod 401 penetrates the collecting box 405 and extends to the outside of the collecting box 405. The dried metal powder falls into the collecting box 405, and the two sets of pull rods 402 are pulled inward at the same time. While pulling, the high-temperature cloth layer 403 moves with the pull rod 402, thereby covering the mouth of the collecting box 405 to prevent the metal powder from escaping during transportation.

[0030] A sliding groove 400 is provided on the inner wall of one side of the collection box 405, and a strip-shaped opening 407 is provided on the surface of one side of the collection box 405. A sliding block 404 is fixedly installed on one end of the pull rod 402, and the sliding block 404 is slidably connected to the inner cavity of the sliding groove 400. The other end of the pull rod 402 passes through the strip-shaped opening 407 and extends to the outside of the collection box 405. The arrangement that one end of the pull rod 402 passes through the strip-shaped opening 407 and extends to the outside of the collection box 405 makes it convenient to hold one end of the pull rod 402 from the outside, so as to unfold the high-temperature resistant cloth layer 403.

[0031] Slide grooves 107 are provided on the inner walls of both sides of the discharge port 109 of the drying cylinder 101 . Slide blocks 108 are slidably connected to the inner cavity of the slide grooves 107 . Two groups of slide blocks 108 are fixedly installed on the corresponding side surfaces of the baffle 105 to limit the movement range of the baffle 105 .

[0032] A fixing plate 202 is fixedly installed on the surface of one side of the baffle 105, a fixing block 201 is fixedly installed on the surface of the drying cylinder 101, an insertion rod 200 is inserted on the surface of the fixing block 201, one end of the insertion rod 200 passes through the fixing block 201 and the fixing plate 202 in sequence, to fix the baffle 105, to prevent the scraper 300 from sliding to one side due to the force generated by the rotation of the scraper 300 during the use of the equipment, and to avoid the metal powder from flowing out of the inner cavity of the drying cylinder 101.

[0033] When the embodiment of the utility model is used, the dryer 104 is started to increase the temperature in the drying cylinder 101, and then metal powder is added to the drying cylinder 101 through the feed pipe 103. When the addition is completed, the drive motor 102 is started, and the drive motor 102 drives the transmission rod 303 to rotate, thereby driving the scraper 300 to rotate continuously along the inner wall of the drying cylinder 101. During the rotation, the scraper 300 continuously lifts the metal powder upward, so that the metal powder is fully mixed with the heat medium in the drying cylinder 101, and the metal powder is dried by the heat medium. In the process of the scraper 300 continuously lifting the metal powder, the scraper 300 continuously beats the metal powder, thereby preventing the metal powder from becoming compacted.

[0034] When the metal powder is dried, the drive motor 102 is controlled to stop rotating, and the dryer 104 is turned off. The plug-in rod is pulled out from the surface of the fixed block 201 and the fixed plate 202 to release the restriction on the baffle 105. At this time, the handle 106 is pulled to one side, and the baffle 105 is pulled outward, so that the dried metal powder falls into the collection box 405. At the same time, the two sets of pull rods 402 are pulled inward at the same time. While pulling, the high-temperature resistant cloth layer 403 moves with the pull rods 402 to cover the mouth of the collection box 405. At this time, the metal powder is transported to the next process, and the winding rod 401 is rotated at the preset position to wind up the high-temperature resistant cloth layer 403.

The above are only preferred embodiments of the present invention and are not intended to limit the present invention. The above embodiments and descriptions in the specification are only intended to illustrate the principles of the present invention. Without departing from the scope of the present invention, any modifications, equivalent substitutions and improvements made within the spirit and scope of the present invention should be included in the protection scope of the present invention.
