A pipe cleaning and drying device

Abstract

The invention relates to the technical field of pipeline engineering, and discloses a pipeline cleaning and drying device, which includes a left outer cylinder, a right outer cylinder, and an inner cylinder arranged between the left outer cylinder and the right outer cylinder. The inner cylinder can Relative to the rotation of the left outer cylinder and the right outer cylinder, an inlet pipe is arranged in the left outer cylinder, and the inlet pipe communicates with the inner cylinder. The outer wall of the cylinder is provided with a cleaning assembly for cleaning the inner wall of the pipeline. The outer wall of the inner cylinder is provided with at least one first nozzle along the circumference. The cleaning or drying medium is passed into the inner cylinder from the inlet pipe and sprayed out from the first nozzle. Since the central axis of the first nozzle forms an included angle with the diameter of the inner cylinder, and forms an included angle with the central axis of the inner cylinder, the cleaning or drying medium sprayed by the first nozzle has a circumferential and axial direction on the inner cylinder. The thrust drives the inner cylinder to rotate, and the driving device moves along the axial direction of the pipeline. The effect of cleaning or drying is good, and the consumption of medium is saved.

Description

technical field [0001] The invention relates to the technical field of pipeline engineering, in particular to a pipeline cleaning and drying device. Background technique [0002] Industrial pipelines usually undergo pressure testing during the construction process. After the pressure test, the pipelines usually need to be cleaned and dried. The pipelines must be cleaned and dried to meet the requirements of specifications or standards before they can be delivered for use. Pipelines are usually also cleaned after a period of use. The conventional industrial pipeline cleaning and drying method is to continuously pass the cleaning and drying medium into the pipeline. The common cleaning medium is clean water, and the common drying medium is compressed air. This cleaning method consumes a lot of cleaning and drying media, especially for cleaning and drying pipelines with medium and large diameters. There have always been problems such as low cleaning efficiency, high labor inte...
