Description

Low-pollution closed underwater pelletizer

Technical Field

Background

The underwater pelletizer is similar to an air flow pelletizer and a water spray pelletizer, and the equipment mainly comprises a plastic pelletizer, a single-screw and double-screw plastic extruder, a plastic film blowing machine, a bag making machine, a printing machine, a coating machine, an adhesive tape splitting machine, a splitting machine and a packing machine. In the aspect of the modification formula, alloy materials are taken as main materials, and particularly PET, PC, ABS, (PP and PA) which are continuously growing in the current application area are taken as the main materials; the plastic formula develops the formulas of preservative film, degradable film, PET tackification and toughening and the like. Except that it has a smooth water flow over the die face in direct contact with the die face. The size of the cutting chamber is just enough to allow the cutter to freely rotate across the die face without limiting the water flow temperature. The molten polymer is extruded from a die, a rotating knife cuts the pellets, and the pellets are carried out of the pelletizing chamber by a temperature-controlled water belt into a centrifugal dryer. In the dryer, the water is drained back to the storage tank, cooled and recycled; the pellets were passed through a centrifugal drier to remove water.

The existing closed underwater pelletizer has simple structure and single function, and can not reasonably screen and recover processed granules, thereby causing pollution.

An effective solution to the problems in the related art has not been proposed yet.
