Embodiment Construction

[0018] Refer to attached figure 1 , 2 , The polystyrene extruded foam insulation pipe production equipment consists of a feeding part, a foaming agent injection part, a No. 1 single-screw extruder 1, a No. 2 single-screw extruder 6 and a double-roller tractor 26. The feeding part is composed of a mixer and a feeding machine. The mixing machine is a commercially available blade type mixer, and the feeding machine is a commercially available screw feeder. The polystyrene raw material passes through the mixing machine and the feeding part The feeder enters the hopper 2 of the No. 1 single-screw extruder 1; the foaming agent injection part includes a foaming agent storage tank and a metering pump. The foaming agent is a carbon dioxide mixed foaming agent or Freon foaming agent. The point is located at the middle end of No. 1 single-screw extruder 1, and the foaming agent is injected through a metering pump, and the metering pump adopts a commercially available metering pump; No. ...

Abstract

The invention relates to equipment and a method for producing polystyrene extruded plastic foam insulated pipes, and belongs to the technical field of polystyrene plastic extrusion foam production. The production equipment consists of a material loading part, a foaming agent filling part, a first single screw extrusion machine, a second single screw extrusion machine, a static mixer, a die head, an extrusion die, a shaping sleeve, and a double-roll tractor. Polystyrene raw material enters the extrusion machine from the material loading part; the foaming agent filling part comprises a foaming agent tank and a metering pump, and the foaming agent is filled by the metering pump; the first single screw extrusion machine and the second single screw extrusion machine are sequentially and serially connected to form an extrusion machine for producing the polystyrene extruded plastic foam insulated pipes; and meanwhile, the barrels of the first single screw extrusion machine and the second single screw extrusion machine are divided into 13 temperature control regions, and an electric heating plate and a temperature sensor are arranged in each temperature control region, wherein the barrel I of the first single screw extrusion machine is divided into 7 temperature control regions and the barrel II of the second single screw extrusion machine is divided into 6 temperature control regions.

Description

technical field [0001] The invention relates to a polystyrene extruded foam insulation pipe production equipment and a production method thereof, which belong to the technical field of polystyrene plastic extrusion foam production, and are mainly used for air pipes, water pipes and oil transportation with a medium temperature below 70 degrees Pipe insulation pipe production. Background technique [0002] In the prior art, polyurethane foam plastics are generally used as pipe insulation, and the production method usually adopts discontinuous extrusion, composite foaming, and single-piece production processes, resulting in low production efficiency, low compressive strength, and relatively high prices. Therefore, the cost of the polyurethane foam insulation pipe is relatively high, and the production process is complicated. Contents of the invention [0003] The purpose of the present invention is to overcome the above disadvantages, a polystyrene extruded foam insulation p...
