Problems solved by technology

[0004] The phase change material and conventional spinning masterbatch are mixed through a twin-screw extruder for granulation, while the die head of a traditional granulator is generally only in a single shape. After long-term use, local pressure unevenness will appear, making the masterbatch The quality of the masterbatch is not high, and it will cause the surface of the masterbatch to be rough and irregular in shape

Abstract

The invention discloses a double-screw extruder die head for phase-change temperature-regulating master batch. The die head comprises a transition plate, a flow stabilizing plate communicating with the transition plate, a forming plate communicating with the flow stabilizing plate and an opening die plate communicating with the forming plate, wherein the transition plate is internally provided with a flow channel a, the flow channel a is a sector-shaped flow channel connected with a barrel of an extruder, the flow stabilizing plate is internally provided with a flow channel b, the flow channelb is a wavy flow channel, and the upper flow channel is parallel to the lower flow channel; a porous plate is arranged between the transition plate and the flow stabilizing plate; the forming plate is also connected with the flow stabilizing plate through mounting bolts, the forming plate is internally provided with a flow channel c, the flow channel c is a right-angle trapezoid flow channel, anda thermocouple is further arranged on the outer side of the flow channel c; and the opening die plate is in a cuboid shape, and a plurality of die holes communicating with the flow channel c are formed in the opening die plate. According to the double-screw extruder die head for the phase-change temperature-regulating master batch, the die head is provided with a flow-stabilizing section, elasticpotential energy in melts can be released conveniently, and meanwhile, the local pressure of the discharge opening die plate can be adjusted.

Description

technical field [0001] The invention relates to the technical field of spinning masterbatch production equipment, in particular to a twin-screw extruder die head for phase-change temperature-regulating masterbatch. Background technique [0002] Phase change energy storage material is a material that absorbs or releases a large amount of latent heat by changing its own phase state when the ambient temperature changes, so that its temperature is basically maintained at a constant value. As an energy storage medium, based on their high energy storage density, phase change energy storage materials have been widely used in various thermal energy-saving applications in recent years. Phase-change energy storage materials include inorganic phase-change materials, such as hydrated salts and metal alloys; organic phase-change materials, such as paraffin, fatty acids, and polyols. [0003] Among the known phase change materials, hydrated salts and metal alloys usually have a high late...
