Abstract

The invention discloses a PVA dry-method vertical melting granulator which comprises a storage box, a microcontroller, a granulator shell, a cooling chamber and a granulation cutter. The storage box is arranged at the top of the granulator shell. The microcontroller is arranged on the left side of an electric heater. Screws and a temperature induction type secondary heater are arranged in the granulator shell. The cooling chamber is arranged at the bottom of the granulator shell. A turbo type fan is arranged on the left outer wall of the cooling chamber. The granulation cutter is arranged at the bottom end in the cooling chamber. The manner of a traditional horizontal granulator is broken through, a vertical structure is adopted, and therefore the occupied area is greatly decreased; the three screws are meshed and connected with gradual type spiral tooth cutters on the inner wall of the temperature induction type secondary heater, so that the overall structure of the granulator shell is more compact; and by means of the more compact structure, the mixing efficiency of starch in polyethylene is higher, the overall production cost is reduced, and the production efficiency is high.
