Elastic cleaning ball, cleaning device, cleaning method and pressure test device and method

Abstract

The invention discloses an elastic cleaning ball, a cleaning device and a cleaning method and a pressure test device and a pressure test method for a pipeline. The elastic cleaning ball comprises an elastic solid core, an elastic reinforcing plate arranged on the rear surface of the elastic solid core and an elastic coating which wraps the elastic solid core and the elastic reinforcing plate. The cleaning device comprises a ball serving device and a ball receiving device which are connected to both ends of the pipeline, and at least one elastic cleaning ball. The elastic cleaning ball is compactly contacted with the inner wall of the pipeline in the cleaning process. According to the cleaning device and cleaning method provided by the invention, the pipeline for conveying ore pulp is efficiently cleaned. The pressure test device comprises a first end water injection device, a water injection pump and a rear end emptying device which are connected to both ends of the pipeline as well as the elastic cleaning ball for emptying air in the pipeline. According to the pressure test device and method provided by the invention, the efficient pressure test efficiency is realized, and air in the pipeline can be completely emptied.

Description

technical field [0001] The invention relates to the application field of pipeline installation and cleaning, more specifically, the invention relates to an elastic cleaning ball for long-distance pulp pipelines, a cleaning device and method using the elastic cleaning ball, and a pressure testing device and method. Background technique [0002] In the field of pipeline installation and application, before the next round of pipeline operations, cleaning and pressure testing operations are usually required to remove residual rust residues or materials and other debris in the pipeline, and the strength and sealing performance of the pipeline need to be checked. test. [0003] At present, there is no effective device for cleaning and pressure testing long-distance pipelines for transporting ore slurry in complex areas with large elevation differences in mountainous and high-altitude areas.

AI Technical Summary

Problems solved by technology

[0003] At present, there is no effective device for cleaning and pressure testing the long-distance pipelines used to transport ore slurry in complex areas with large elevation differences in mountainous and high-altitude areas.

On the one hand, because the ore slurry transported by the pipeline contains more impurities, such as large-sized crushed stones, ores, etc.; on the other hand, the pipeline has a large drop, a large length, and many bends, which are generally wavy. shape, which brings great difficulties to cleaning and pressure testing, and often requires multiple cleanings or multiple pressure tests, and the effect of cleaning and pressure testing is not ideal, and the efficiency is low

At the same time, due to the long pipeline, if an exhaust valve is installed in the pipeline during the pressure test, the air will be greatly compressed, resulting in unsatisfactory emptying effect, and even invalid pressure test
