[0004] The above scheme can achieve the purpose of fast and simple material feeding and discharging. However, the above scheme has certain shortcomings in actual use. Although the powder is fed through the inner cavity of the hopper, the powder passes through the inner cavity of the drop column and falls into the barrel cavity, completing simple feeding and feeding, the powder itself may be seriously damp. The damp powder is easy to adhere to the inner wall of the drop column during the process of falling through the drop column. As time goes by, this adhesion phenomenon accumulates, resulting in the gradual reduction of the effective passing diameter inside the drop column, which seriously affects the smooth flow of materials. This blockage phenomenon not only reduces the drying efficiency, but also may cause equipment failure, increase maintenance costs, and threaten the continuous and stable operation of the production line.

[0019] like Figures 1 to 4 As shown, a stainless steel powder material drying device includes a drying box 1, and a feeding assembly 2 is arranged above the drying box 1.

[0020] The feeding assembly 2 includes a drop tube 201, and the bottom of the drop tube 201 is fixedly connected to the interior of the drying box 1, and the top of the drop tube 201 is fixedly connected to a guide hopper 202.

[0021] By correctly connecting the positive and negative electrodes of the battery to the two ends of the second heating wire 204, the second heating wire 204 can be operated to generate heat.

[0022] The stainless steel powder material to be dried is put into the guide hopper 202, and the material will slide into the inner side of the drop tube 201. The second heating wire 204 heats the second heating chamber 203, so that the inner wall of the drop tube 201 can dry a small amount of wet powder material adhering to the inner wall of the drop tube 201, thereby preventing the wet material from adhering to and accumulating on the inner wall of the drop tube 201 and causing blockage.

[0023] A conveying mechanism 3 is provided above the drying box 1 .

[0024] The conveying mechanism 3 includes a support plate 301 , and the outer surface of the support plate 301 is fixedly connected to the top of the drying box 1 , and a first motor 302 is fixedly mounted on the upper surface of the support plate 301 .

The outer surface of the first rotating shaft 303 is fixedly connected to the spiral blade 304 , and the outer surface of the spiral blade 304 contacts the inner wall of the blanking tube 201 .

[0026] By turning on the first motor 302, the first rotating shaft 303 can be driven to rotate, and then the first rotating shaft 303 will drive the spiral blade 304 to rotate along, and the rotating spiral blade 304 will drive the material on the inner side of the drop tube 201 to be transported downward, and then the material can be transported into the drying box 1. At the same time, the second heating chamber 203 is heated by the second heating wire 204, so that the inner wall of the drop tube 201 can dry a small amount of moist powder material adhering to the inner wall of the drop tube 201, and then the spiral blade 304 can scrape the dried material on the inner wall of the drop tube 201.

[0027] A stirring mechanism 4 is provided inside the drying box 1 .

[0028] The stirring mechanism 4 includes a second motor 401, and the second motor 401 is fixedly installed on the top of the drying box 1. The output end of the second motor 401 is fixedly connected to a second rotating shaft 402, and the second rotating shaft 402 rotates with the drying box 1. The outer surface of the second rotating shaft 402 is fixedly connected to a stirring rod 403.

[0029] A cleaning scraper 404 is fixedly connected to the outer surface of the second rotating shaft 402 , and the bottom surface of the cleaning scraper 404 is in contact with the inner bottom wall of the drying box 1 .

[0030] By turning on the second motor 401, the second rotating shaft 402 can be driven to rotate, and then the second rotating shaft 402 will drive the stirring rod 403 and the cleaning scraper 404 to rotate accordingly. At this time, the stirring rod 403 can evenly stir the powder material inside the drying box 1, so that the material can contact the inner wall of the drying box 1, and then the powder material can be dried. During the rotation process, the cleaning scraper 404 can hang the small amount of material remaining at the bottom of the drying box 1 into the discharge hopper 5, so that the material can be quickly discharged.

[0031] A discharge hopper 5 is provided at the bottom of the drying box 1 .

[0032] A control valve is installed on the discharge hopper 5, which can facilitate the control of the discharge operation of the dried material.

[0033] A first heating chamber 6 is provided inside the drying box 1 , and a first heating wire 7 is installed inside the first heating chamber 6 .

[0034] By correctly connecting the positive and negative electrodes of the battery to the two ends of the first heating wire 7, the first heating wire 7 can be operated to generate heat.

[0035] Two groups of supporting legs 8 are fixedly connected to the bottom surface of the drying box 1 .

[0036] Working principle: When the utility model is in use, it is first necessary to turn on the external power supply to energize the second heating wire 204 and the first heating wire 7. After the temperature in the second heating chamber 203 and the first heating chamber 6 reaches the specified temperature, the first motor 302 and the second motor 401 can be turned on by the external controller, and then the stainless steel powder material to be dried is put into the guide hopper 202, and the material will slide into the inner side of the drop tube 201. At this time, the first motor 302 is turned on to drive the first rotating shaft 303 to rotate, and then the first rotating shaft 303 will drive the spiral blade 304 to rotate with it. The rotating spiral blade 304 will drive the material inside the drop tube 201 to be transported downward, and then the material can be transported into the interior of the drying box 1. At the same time, the second heating wire 204 heats the second heating chamber 203, so that the inner wall of the drop tube 201 can dry a small amount of moist powder material adhering to the inner wall of the drop tube 201, and then the spiral blade 304 can scrape the dried material on the inner wall of the drop tube 201. The scraped material is then transported into the interior of the drying box 1 to avoid clogging of the drop pipe 201. The feeding assembly 2 and the conveying mechanism 3 cooperate with each other to ensure smooth flow of the material, thereby ensuring the subsequent drying efficiency of the powder material. At the same time, the first heating chamber 6 will have a certain temperature due to the heating of the first heating wire 7, which will make the inner wall of the drying box 1 have a certain temperature. By turning on the second motor 401, the second rotating shaft 402 can be driven to rotate, and then the second rotating shaft 402 will drive the stirring rod 403 and the cleaning scraper 404 to rotate accordingly. At this time, the stirring rod 403 can evenly stir the powder material inside the drying box 1, so that the material can contact the inner wall of the drying box 1, and then the powder material can be dried. The discharge hopper 5 is opened to discharge the dried material inside the drying box 1. At the same time, the cleaning scraper 404 during the rotation process can hang the small amount of material remaining at the bottom of the drying box 1 into the discharge hopper 5, so that the material can be quickly discharged.
