Description

Technical Field

[0001] The utility model relates to the technical field of air duct cooling, in particular to a 180-degree adjustable air duct cooling device for a twin-screw extruder granulator. Background Art

[0002] Granulation is a dispersion in which solid powder and liquid coexist and the solid phase is the main phase. The self-adhesiveness of the dispersion is used to force the basic particles of solid powder to adhere to each other and increase in size, forming a certain shape and uniform particle size. The concentrated particle group is called a granulator, and the commonly used one is a twin-screw extruder granulator.

[0003] The twin-screw extruder granulator is equipped with an air duct to dry the granulated particles. The existing air duct can adjust the wind direction by 180° at the outlet end to increase the blowing range. However, the air duct will be very hot if the high-temperature gas passes through it for a long time. If the air duct is in a high-temperature state for a long time, it will easily cause the air duct to be damaged. A cooling mechanism will be set on the air duct, which is basically a sleeve on the air duct, and the heat is taken away by the coolant in the sleeve. The existing sleeve has a certain length, which will take up more space when carrying and installing. If it is short, it will not have a good cooling effect.

[0004] In view of this, we propose a 180-degree adjustable air duct cooling device for the twin-screw extruder granulator. Utility Model Content
