Inner wall cleaning device for polyethylene composite pipe

Abstract

The invention discloses an inner wall cleaning device for a polyethylene composite pipe. The inner wall cleaning device comprises a fixing shell, wherein the inner side of the fixing shell is fixedlyconnected with one ends of supporting rods which are evenly distributed, the other ends of the multiple supporting rods are fixedly connected with a communicating ring, and an air hole is formed in the inner side of the communicating ring; and uniformly distributed shells are fixedly connected to the outer side of the communicating ring, a sliding plate is slidably connected to the inner side of each shell, one end of a push rod is fixedly connected to the side, away from the communicating ring, of each sliding plate, a supporting block is fixedly connected to the other end of each push rod, and a rotating rod is rotatably connected to the inner side of each supporting block. In conclusion, the inner wall cleaning device can clean pipelines with different diameters, can clean long pipelines, can stably move, can remove cleaned impurities, does not need to be cleaned by workers after cleaning is completed, and is convenient to treat, good in cleaning effect and high in efficiency.

Description

technical field [0001] The invention relates to the technical field of inner wall cleaning, in particular to an inner wall cleaning device for polyethylene composite pipes. Background technique [0002] Polyethylene composite pipe refers to the use of two polyethylene resins with different densities, which are plasticized and melted by two extruders at the same time, and then the molten material is extruded into a mold capable of forming composite pipes at the same time. Ethylene composite pipe, this kind of composite pipe can be extruded and compounded by various plastics. The pipe formed by compounding high-density polyethylene and low-density polyethylene has the characteristics of both materials. Its pressure resistance and corrosion resistance are better than Ordinary polyethylene pipe is fine. In industrial and mining enterprises, this kind of composite pipe can be used instead of steel pipe, and it can be used for conveying pipes of corrosive media such as oil and ga...

AI Technical Summary

Problems solved by technology

[0003] When polyethylene composite pipes are used, due to long-term transportation, impurities will accumulate on the inner wall of the pipe, reducing the efficiency of transportation, and the inner wall of the pipe needs to be cleaned. However, the existing cleaning device has poor cleaning effect. Long, it is difficult to clean long pipes, and the impurities cleaned are not easy to remove, and pipes of different sizes and diameters cannot be cleaned
