Novel PE pipe preparation device

Abstract

The invention discloses a novel PE pipe preparation device, which comprises an extruder main body for extruding polyethylene particles into a pipe structure and a base fixedly mounted at the bottom of the extruder main body, the base is used for bearing the extruder main body, a water tank is arranged on the base, and the water tank is used for collecting cooling water for cooling; a rolling mechanism arranged on the periphery of the pipe and used for dragging and assisting the movement of the pipe and cooling the pipe; and supporting mechanisms are symmetrically arranged on the base, and the supporting mechanisms are used for supporting the rolling mechanism on the base. According to the novel PE pipe preparation device provided by the invention, a gap exists between a first rolling wheel and the pipe, the gap is filled with cooling water flowing out of a water outlet, the flow speed of the cooling water is reduced after the cooling water is buffered by the first rolling wheel, and due to the surface tension effect of water, the pipe is comprehensively wrapped, so that the pipe can be very effectively cooled in the pipe output process.

Description

technical field [0001] The invention belongs to the technical field of tower crane foundations, and in particular relates to a preparation device for a novel polyethylene PE pipe. Background technique [0002] Polyethylene is a kind of thermoplastic resin obtained by polymerization of ethylene. Because it is odorless, non-toxic, and feels like wax, it has excellent low temperature resistance, and the lowest use temperature can reach -100 ~ -70 ° C. It has good chemical stability. , resistant to most acid and alkali erosion, insoluble in general solvents at room temperature, low water absorption, excellent electrical insulation, PE resin is polymerized from monomer ethylene, due to different polymerization conditions such as pressure and temperature during polymerization, Resins with different densities can be obtained, so there are high-density polyethylene, medium-density polyethylene and low-density polyethylene. When processing different types of PE pipes, different resin...

Problems solved by technology

[0003] The preparation method of PE pipe generally has the method of extrusion, which can be extruded by an extruder. The extruded pipe still has a certain temperature, and the shape is not stabilized. Afterwards, it needs to be cooled. At the same time, the pipe with a certain temperature In the process of transmission and traction, it is also necessary to keep the shape stable, but the formed pipe with a certain temperature is still in the process of being transported backward and cooled, and it is easy to be unbalanced due to suspension during the traction process, and cooling water impact, causing deformation of the newly formed pipe
