Abstract

The utility model provides a PE plastic pipe high-yield screw, which adopts a three-section structure, i.e. a feeding section, a melting section and an extrusion section in sequence, wherein the feeding section adopts a single screw thread structure; the melting section adopts a double screw thread separated type structure; and the extrusion section adopts a mixing type structure. The feeding section adopts the single screw thread structure, thus being favorable for the high-speed and stable delivery of materials; the melting section adopts the double screw thread separated type structure, thus being favorable for the melting and the plasticizing of the materials; and the extrusion section adopts a mixing type structure, thus being favorable for the mixing and the high-yield extrusion of the materials. The yield can reach 350-400kg/h which can be compared with that of oversea first-rate corporations.

Description

A kind of PE plastic pipe high yield extrusion screw rod
Technical field
The utility model belongs to the screw rod field of pipe extruder, particularly relates to a kind of PE plastic pipe high yield extrusion screw rod.
Background technology
Extrude the field at the PE plastic pipe, in the domestic extruder commonly used, output is all lower, can't satisfy the production needs of heavy caliber pipe at present.With Φ 65 single screw extrusion machines is example, and the output of Φ 65 single screw extrusion machines of general manufacturer production is usually at 120～160kg/h, and the output of Φ 65 single screw extrusion machines of better manufacturer production is usually at 200～250kg/h.This output is far below external advanced level.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of extrusion screw rod of high yield is provided.
To achieve these goals, the technical scheme of employing is as follows:
A kind of PE plastic pipe high yield extrusion screw rod adopts three stage structure, is followed successively by feeding section, melt zone, extruding zone, and feeding section adopts the one start screw structure, and melt zone adopts the separation-type structure of double thread, and extruding zone adopts the mixed milling type structure.
In the technique scheme, the length of described melt zone is feeding section or mixing section 1.5～2 times.
The screw thread of described extruding zone adopts gear structure.
The draw ratio of described screw rod is 34.
The utility model is contained on the extruder, cooperates the reinforced lining of fluting, and the PR common screw exceeds 30%～40%.Screw slenderness ratio is bigger, is 34, is divided into three sections of feeding section, melt zone and extruding zones.Feeding section adopts single-threaded structure, and the high speed that helps material is stable carries; Melt zone adopts the separation-type structure of double thread, helps the fusion plastification of material; Extruding zone adopts the structure of mixed milling type, and the mixing and high yield that helps material is extruded, and output can reach 350～400kg/h, can compare with external leading company.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A cutaway view Amplified image of Fig. 1.
The specific embodiment
Structural representation of the present utility model as shown in Figure 1, screw rod is divided into three sections of feeding section 1, melt zone 2 and extruding zones 3 (mixing section).Feeding section 1 adopts single-threaded structure, and the high speed that helps material is stable carries; Melt zone 2 adopts the separation-type structure of double thread, helps the fusion plastification of material; Extruding zone 3 adopts the structure of mixed milling type, is called " mixing section " again, and the mixing and high yield that helps material is extruded.The screw thread of extruding zone 3 adopts gear structure, as shown in Figure 2.
The utility model is contained on the extruder of applicant's production, cooperates the reinforced lining of fluting, and the PR common screw exceeds 30%～40%, can reach 350～400kg/h, can compare with external leading company.
