HDPE multi-rib reinforced winding corrugated pipe and production method and device

Abstract

According to the HDPE multi-rib reinforced winding corrugated pipe disclosed by the invention, through cooperative use of the vertical ribs, the reinforcing ribs and the supporting ribs, when the surface of the winding pipe is subjected to pressure of a soil layer, the umbrella-shaped structures can play a role in supporting the winding pipe, so that the winding pipe is not liable to collapse and has the advantage of high impact resistance, and the ring stiffness of the winding corrugated pipe is effectively improved. According to the production method of the HDPE multi-rib reinforced winding corrugated pipe, the advantage of being easy and convenient to operate is achieved, the quality of the produced HDPE multi-rib reinforced winding corrugated pipe is high, and the percent of pass of products is greatly improved; according to the production device of the HDPE multi-rib reinforced winding corrugated pipe, the gear motor can be used for driving the movable plate, the stirring rod and the inclined rod to move synchronously, and the purposes of saving energy and electricity can be achieved without using a plurality of gear motors for driving; and meanwhile, in the process of screening the raw materials through the screening mechanism, the raw materials can make full contact with heat, and the drying effect is further improved.

Description

technical field [0001] The invention relates to the technical field of helical corrugated pipes, in particular to HDPE multi-rib reinforced winding corrugated pipes and a production method and device. Background technique [0002] Because the spiral corrugated pipe is first heated and drawn into a strip-shaped profile, and then heated and melted PE plastic is injected into the gap between the strip-shaped windings during the pipe making process, the strip-shaped polyethylene plastic is bonded together. , the formation of winding corrugated pipe. [0003] The existing winding corrugated pipe has poor anti-compression effect, and it is easy to be damaged when being squeezed, which affects the use effect of the winding corrugated pipe; secondly, the raw material of the current winding corrugated pipe is extruded through an extruder during the production process. The structure of the hopper of the extruder is simple, the raw materials are directly poured into the hopper, the ra...

AI Technical Summary

Problems solved by technology

[0003] The existing wound corrugated pipes have poor compression resistance and are prone to damage when being squeezed, which affects the use effect of the wound corrugated pipes; secondly, the raw materials of the wound corrugated pipes are extruded through an extruder during the production process, but The hopper of the extruder has a simple structure, and the raw materials are poured directly into the hopper without any treatment on the raw materials. There is a certain amount of moisture in the raw materials, which will cause the raw materials to evaporate during the melt extrusion process and generate air bubbles, resulting in pits on the surface of the winding bellows. The phenomenon occurs; at the same time, when the raw materials enter the extruder, it is not convenient to screen the raw materials, resulting in poor quality of the molten body after the raw materials pass through the extruder, which in turn affects the molding quality of the winding bellows
