[0021] By using the first supporting bevel 12 and the second supporting bevel 15, sodium antimonate enters the interior of the drying box 11 through the feed hopper 14. When it falls to the surface of the first ceramic heating plate 13 on the top of the first supporting bevel 12, the sodium antimonate is heated and dried by the first ceramic heating plate 13 and the second ceramic heating plate 16, respectively, so that the sodium antimonate is gradually dried in the process of sliding. At the same time, it slides from the first ceramic heating plate 13 to the surface of the second ceramic heating plate 16, so that the sodium antimonate is heated more evenly, thereby improving the drying efficiency of the sodium antimonate.

[0022] The hot air blower 17 disposed at the bottom of the drying box 11 is used to avoid direct air drying of the sodium antimonate, which would cause dust to be raised. At the same time, the airflow generated by the hot air blower 17 discharges the water vapor through the dehumidification device 3.

[0023] Among them, the dehumidification device 3 includes a condensation hood 31, which is fixedly installed on the side of the top of the drying box body 11 away from the feed hopper 14, a material guide groove 34 is provided at one end of the bottom of the condensation hood 31, and the material guide groove 34 is an inclined surface, an exhaust port 32 is provided at the top of the condensation hood 31, the material guide groove 34 is connected with the exhaust port 32, a semiconductor refrigeration plate 33 is fixedly connected to one side of the interior of the condensation hood 31 at the bottom of the exhaust port 32, a guide groove 35 is provided on the side of the interior of the condensation hood 31 away from the material guide groove 34, a drain pipe 36 is fixedly connected to one side of the guide groove 35, and a surface of the guide groove 35 is provided with an inclined surface opposite to the material guide groove 34, water vapor passes through the material guide groove 34, is discharged from the exhaust port 32, and is actively condensed by the semiconductor refrigeration plate 33, the condensed dew falls due to the influence of gravity, flows into the interior of the drain pipe 36 through the inclined surface of the guide groove 35, and the condensed water is discharged by connecting a water pipe to one end of the drain pipe 36.

[0025] The outer surface of the crushing roller 49 is provided with protrusions 410 , and the filter screen 41 is made of elastic material, and the crushing roller 49 is rollingly installed on the top of the filter screen 41 .

[0026] Taking advantage of the elastic material of the filter 41, when the crushing roller 49 moves on the surface of the filter 41, the sodium antimonate powder that has condensed into blocks is squeezed between the filter 41 and the crushing roller 49, and the crushing effect of the sodium antimonate powder is improved by the protrusions 410 on the surface of the crushing roller 49. At the same time, the crushing roller 49 will cause the filter 41 to vibrate during the rolling process of the crushing roller 49 on the surface of the filter 41, thereby improving the filtration efficiency of the sodium antimonate powder on the surface of the filter 41.

[0027] The working process of the utility model is as follows:

[0028] When in use, the sodium antimonate powder enters the interior of the drying box 11 from the feed hopper 14 through the external feeding device, and when it falls to the surface of the first ceramic heating plate 13 at the top of the first supporting inclined block 12, the sodium antimonate is heated and dried by the first ceramic heating plate 13 and the second ceramic heating plate 16, respectively, so that the sodium antimonate is gradually dried during the sliding process, and the hot air blower 17 provided at the bottom of the drying box 11 is cooperated with. The hot air generated by the hot air blower 17 passes through the surface of the second ceramic heating plate 16 and the top of the first ceramic heating plate 13, and while drying the sodium antimonate, the airflow generated by the hot air blower 17 discharges water vapor through the dehumidification device 3;

[0029] The water vapor passes through the guide groove 34 and is discharged from the exhaust port 32. At the same time, it is actively condensed by the semiconductor cooling sheet 33. The condensed dew falls due to gravity and flows into the inside of the drain pipe 36 through the inclined surface of the guide groove 35.

[0030] When the sodium antimonate on the surface of the first ceramic heating plate 13 slides into the surface of the filter 41, the driving motor 43 controls the driving gear 44 to rotate clockwise and then counterclockwise. The driving gear 44 is engaged with the fixed rack 46 to control the movable rod 45 to reciprocate inside the drying box 11, so that when the crushing roller 49 moves on the surface of the filter 41, it is squeezed between the filter 41 and the crushing roller 49, so that the sodium antimonate powder that has condensed into blocks is crushed. While the convex points 410 on the surface of the crushing roller 49 improve the crushing effect of the sodium antimonate powder, the crushing roller 49 rolls on the surface of the filter 41, which causes the filter 41 to vibrate. The sodium antimonate powder falls onto the surface of the second ceramic heating plate 16, and falls to the conveyor belt 2 through the guide nozzle 18, and is transmitted to other processes through the conveyor belt 2.
