Abstract:
1, double cone vacuum dryer tank inside the filter position is up.2, whether the filter on the process requirements, with industrial filter cloth.
1, double cone vacuum dryer tank inside the filter position is up.
2, whether the filter on the process requirements, with industrial filter cloth.
3, close the feed / discharge hole cover.
4, the feed hole cap on the tube to remove the tube, put the feed to take over (user self).
5, open the vacuum pump, the tank reaches a certain degree of vacuum, the tube into the powder, the use of vacuum inhalation of materials into the tank, the amount of charge shall not exceed 50% of the total volume, and the material shall not have a hard block Things. If the material density or water content is too large, should be appropriate to reduce the amount of feed.
6, pumping finished, the inlet directly connected to the atmosphere, close the vacuum pipe on the valve, remove the feed pipe, loaded the tube cap, and to ensure its sealing.
7, open the vacuum pipe valve, so that the tank to a certain degree of vacuum.
8, open the jacket heating steam (or hot water) inlet valve, the tank material heating and drying, but in the beginning of the drying process should be intermittent rotation to reduce or eliminate the phenomenon of material agglomeration.
9, open the double cone vacuum dryer host start button, so that the container is constantly rotating around the horizontal axis.
10, according to operational experience, the amount of coal recovery, the temperature inside the device, in the confirmation of the tank material drying process has ended, cut off the steam (or hot water) and vacuum pipe valve, and then slowly to the jacket through the cooling Water, and other materials cooled to the appropriate temperature, press the host to stop the button, and use the jog button to allow the tank to the desired angle.
11, close the vacuum pump, open the vacuum pipe valve, open the vacuum system on the vent valve, so that the tank connected to the atmosphere.
12, open the discharge hole cover discharge.
13, cleaning the remaining material in the tank, close the discharge hole cover, to prevent dust into the double cone vacuum dryer tank.
