At the same time, the connecting rod 10 drives the blade 9 to rotate, so that the NdFeB permanent magnet electroplating products inside the filter drum 8 are dried evenly. Multiple rubber blocks 14 installed on the outside of the blade 9 prevent the NdFeB permanent magnet electroplating products from contacting the inner wall of the filter drum 8 during the drying process.

[0024] like Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, the interior of the connecting rod 10 is hollow, and a plurality of small holes are opened on the outside of the connecting rod 10;

[0025] The blade 9 is cross-shaped, and the interior of the blade 9 is hollowed out, and a plurality of spray holes are opened on the outer surface of the blade 9;

[0026] The interior of the connecting rod 10 is communicated with the interior of the blade 9 , and the exterior of the blade 9 is in contact with the inner side of the filter cartridge 8 .

[0027] The above scheme is adopted: by placing the NdFeB permanent magnet electroplating finished product into the filter cylinder 8, starting the motor 5 to drive the connecting rod 10 and the drying cylinder liner 7 to rotate, and drying the NdFeB permanent magnet electroplating finished product. When the hot air blower 4 is started, the hot air enters the first connecting ring 11 and the second connecting ring 12 along the connecting pipe 6, and at the same time enters the connecting rod 10 through the circular hole 13.

[0029] The inner diameter of the spin-drying drum liner 7 is equal to the outer diameter of the filter drum 8, and one end of the connecting rod 10 passes through the bottom of the spin-drying drum liner 7 and the filter drum 8;

[0030] The fixing assembly 15 also includes a round block 1507 installed at the bottom of the filter cartridge 8, a second connecting rod 1503 fixedly connected to the top surface of the round block 1507, a spring 1505 arranged on the outside of the second connecting rod 1503, a fixing plate 1502 sleeved on the outside of the second connecting rod 1503, a first connecting rod 1501 installed on the top surface of the fixing plate 1502, a long block 1504 fixed to the top of the second connecting rod 1503, a fixing block 1508 is provided on the outside of the round block 1507, and a circular groove is opened inside the fixing block 1508.

The motor 5 drives the connecting rod 10 to rotate, and at the same time, the connecting rod 10 drives the filter barrel 8 to rotate along the inner wall of the spin-drying barrel liner 7. The rotation of the filter barrel 8 throws out the moisture on the surface of the NdFeB permanent magnet electroplating product, so that the water flows into the spin-drying barrel shell 1 along the filter hole outside the filter barrel 8 and is discharged through the drain port 3. At the same time, the hot air blower 4 is started. The hot air blower 4 injects hot air into the interior of the connecting tube 6, and is connected to the outside of the first connecting ring 11 and the second connecting ring 12 through the connecting tube 6, so that the hot air enters the second connecting ring 12 and the first connecting ring 11 and enters the connecting rod 10 along the circular hole 13. At the same time, the hot air moves along the interior of the connecting rod 10 to the drying drum shell 1, and is connected to the interior of the blade 9 through the interior of the connecting rod 10, so that the hot air flows out along the nozzle opened on the outer surface of the blade 9, and the NdFeB permanent magnet electroplated products inside the filter drum 8 are quickly dried. At the same time, the connecting rod 10 drives the blade 9 to rotate, so that the NdFeB permanent magnet electroplated products inside the filter drum 8 are dried evenly. Multiple rubber blocks 14 installed on the outside of the blade 9 prevent the NdFeB permanent magnet electroplated products from contacting the inner wall of the filter drum 8 during the drying process.
