When uniform high-temperature molten material enters a cutting grinding disc flow channel from the tail end of upstream equipment (a reaction kettle/a screw extruder/a melt pump and the like), the material is cut into drops by a granulator blade rotating at high speed and enters processing water when the material just leaves a die hole of a die, so that the particles need to be dehydrated in the subsequent use process.

Traditional particle dewatering device discloses vertical circulation hydroextractor like chinese patent CN201621209909.9, and it includes main platform, centrifugal dehydrator and circulation tank, circulation tank installs on the main platform, centrifugal dehydrator sets up through a hydroextractor mounting bracket on the main platform, the hydroextractor mounting bracket is located circulation tank one side, this hydroextractor can have following problem at the in-process of in-service use:

1. the dehydration effect is poor, and moisture exists in the particles after dehydration treatment, especially in some particles with strong water-absorbing property.

2. The first water filter is provided with the block blocking net but is not provided with the partition plate, so that the situation that partial water-containing particles are sputtered out of a catching block port after contacting the block blocking net can occur, or large particles can block the block blocking net under the situation of long-term use, and the filtering effect of the particles entering the dehydrator can be influenced.

To this end, we propose a particle dehydrator.
