Water scale cleaning device for hot water pipeline

Abstract

The invention discloses a water scale cleaning device for a hot water pipeline. The device comprises a power remote control car, a driving mounting box body and a connecting telescopic pipe. The outer end of a fixed inner barrel is sleeved with a rotating outer barrel, a bend cleaning mechanism is arranged on a reciprocating sliding block, a first scraping mechanism is arranged on a rotating connecting shaft located at the front end, a second scraping mechanism is arranged on the rotating connecting shaft located at the rear end, and a water scale collecting mechanism is arranged at the lower end of the driving mounting box body located at the rear end. According to the water scale cleaning device for the hot water pipeline, the first scraping mechanism and the second scraping mechanism are used in cooperation so that water scale in a straight channel end of the heat distribution pipeline can be removed, water scale in bent segments of the heat distribution pipeline can be removed through the arranged bend cleaning mechanism, and the water scale cleaning efficiency is further improved; and because the water scale collecting mechanism used in cooperation to collect scraped water scale, it is avoided that the scraped water scale is accumulated again to cause pipeline blockage.

Description

technical field [0001] The invention relates to the technical field of thermal pipelines, in particular to a scale cleaning device for hot water pipelines. Background technique [0002] Heat pipe network, also known as heat pipe, starts from the boiler room, direct-fired machine room, heating center, etc., and leads from the heat source to the heat supply pipe of the building's heat entrance. Multiple heat supply pipes form a pipe network, and the design of the heating water medium The pressure is less than or equal to 2.5MPa, the design temperature is less than or equal to 200°C; the design pressure of the heating steam medium is less than or equal to 1.6MPa, and the design temperature is less than or equal to 350°C. In the design of the following heating networks, after a long period of heating, the heat pipes will Since the heating circulating water contains a large amount of scale, the scale will accumulate on the inner wall of the heating pipe to form a layer of scale, ...

AI Technical Summary

Problems solved by technology

[0003] The main purpose of the present invention is to provide a scale cleaning device for hot water pipelines, which can effectively solve the problems in the background technology: the existing thermal pipelines are not all straight channels and most of them are designed with curved sections. The pipeline scale cleaning device can only clean the straight pipeline, and cannot clean the scale inside the curved section of the thermal pipeline well. Moreover, some of the existing curved section cleaning devices are fixed on each fixed curved section. Most of the pipe network is arranged with long pipelines and many curved sections. It is necessary to install a cleaning device in each curved section, which is labor-intensive, increases cleaning costs, and is not convenient for scale cleaning of thermal pipelines.
