Description

Cooling system of double-screw extruder

Technical Field

The utility model relates to a processing equipment, in particular to double screw extruder's cooling system.

Background

Reinforced plastics are thermosetting resins reinforced with glass fibers, commonly known as glass reinforced plastics. The processing equipment made of the composite material is a processing system with a double-screw extruder as main equipment, the double-screw extruder is developed on the basis of a single-screw extruder, and the composite material has the characteristics of good feeding performance, mixing and plasticizing performance, exhaust performance, extrusion stability and the like, so that the composite material is widely applied to the molding processing of extruded products at present. The cooling device comprises a jacket arranged on the outer wall of a cylinder of the double-screw extruder, wherein a water inlet and a water outlet are formed in the jacket, a heat exchange water tank is arranged below the cylinder and is respectively communicated with the heat exchange water tank through a pipeline, the heat exchange water tank is connected with a cooling water tower, and cooling fins are further arranged on the pipeline. As shown in fig. 1, the plastic fiber at the outlet of the twin-screw extruder in the prior art is cooled after passing through the cooling water tank, but after being cooled by the device, the material of the plastic fiber needs to be sent to the cutting machine through a conveying process before entering the cutting device for cutting.
