Detailed Description
As shown in FIG. 1, the powder may be dried while the powder is being loaded. The vacuum feeding drying device is characterized in that dry hot air is provided by an air energy hot air circulation dryer 1, the dry hot air is sent into a closed powder storage box 2 through a dry hot air supply opening through a hot air pipe 7, a powder output opening of the powder storage box 2 is connected with a vacuum feeding machine 3 through a powder pumping pipe 9, the vacuum feeding machine 3 provides negative pressure for the powder storage box 2, and the powder is pumped out of the powder storage box 2 through pressure difference formed by positive pressure of the dry hot air input into the powder storage box 2. Because the powder storage box 2 is closed, external air can not enter, the extracted powder is mixed with dry hot air, and in the conveying process, moisture in the powder is exchanged with the dry hot air, so that the powder is dried. Air can heated air circulation desiccator 1 is including heating and condensation dehumidification two parts, can adjust output hot-air's temperature, dryness fraction (humidity), amount of wind isoparametric respectively, the control range of temperature: and (4) adjusting the maximum dehumidification rate to 40-80 ℃ according to the requirement of the water content of the powder.
