Corrugated pipe extrusion equipment

Abstract

The invention discloses corrugated pipe extrusion equipment. The corrugated pipe extrusion equipment comprises a first melt pump and a second melt pump which are connected to a die head, wherein the first melt pump communicates with a first flat double extruder, the second melt pump communicates with a second flat double extruder, the first flat double extruder is provided with a first powder feeding machine and a first plastic feeding machine and is connected with a first single-screw extruder through a first screen exchanger, the first single-screw extruder is provided with a third plastic feeding machine, the second flat double extruder is provided with a second powder feeding machine and a second plastic feeding machine and is connected with a second single-screw extruder through a second screen exchanger, and a fourth plastic feeding machine is arranged on the second single-screw extruder. By means of the corrugated pipe extrusion equipment, the situation that filling powder must be granulated by a flat double granulator or an internal mixer before being fed into the single-screw extruders in the traditional technology is reduced, and meanwhile, the process that plastic pipeline crushed materials must be granulated by a plastic granulator in the traditional technology is also reduced.

Description

technical field [0001] The invention relates to the field of corrugated pipe extrusion processing, in particular to a corrugated pipe extrusion equipment. Background technique [0002] Traditional bellows equipment extruders are generally single-screw or conical twin-screw. Before the filling powder is put into the single-screw, it must be granulated by a flat-twin granulator or an internal mixer. A large amount of lubricants, coupling agents and dispersants should be added to form particles and then mixed with plastic pipe crushed material to pass through the plastic granulator made by the granulator or mixed with new plastic granules, and the filled granules and plastic granules can be mixed before being put into single-screw extrusion Machine extrudes the pipe. During the use of this structure, the added amount of lubricant, coupling agent and dispersant is increased, resulting in an increase in cost; moreover, the process is relatively complicated, which easily causes w...
