Background
Lines or pipes connected to pumps, valves or control systems, etc., may be used to transport liquids, gases or powdered solids. After the pipeline is used for years, scales are easily remained in the pipeline or the pipeline, so that the inner pipe diameter is reduced, the conveying efficiency is influenced, and the pipeline or the pipeline needs to be cleaned regularly.
The prior scale cleaning device mainly comprises a cutter head and a blade, and is driven by high-pressure water to rotate in a pipeline or a pipeline so as to clean the scale on the inner wall of the pipeline or the pipeline. In order to ensure the cleaning effect, the outer diameter formed by the blades in the scale cleaning device is slightly smaller than the inner wall of the pipe body. Because the situation that partial dirt is difficult to clean can occur in the pipeline or the pipeline, the dirt cleaning device is blocked, the dirt cleaning device cannot be automatically taken out, the operation of taking out the dirt cleaning device is particularly complex, and the practicability is poor.
For example, chinese patent No. CN207430834U discloses a high-pressure rotary pipeline scale cleaner, which comprises a hemispherical large cutter head and a hemispherical small cutter head; the large cutter head and the small cutter head are oppositely arranged, and the diameter of the opening of the large cutter head is larger than that of the opening of the small cutter head; the centers of the ends of the large cutter disc and the small cutter disc are respectively in rotating connection with bearings at two ends of the main shaft; a large impeller is arranged on the inner side of the large cutter disc, and a small impeller is arranged on the inner side of the small cutter disc; the middle parts of the large impeller and the large cutter head are in rotary connection with a first bearing through a large bolt, and the first bearing is fixed at one end of the main shaft; the small impeller and the middle part of the small cutter head are in rotating connection with a second bearing through a small bolt, and the second bearing is fixedly connected with the other end of the main shaft; the working process is as follows: after the high-pressure rotary scale remover for the pipeline is placed in the pipeline, when the scale remover moves forwards for removing scales, water flows through the periphery of the rear end blade due to the small diameter of the rear end blade and acts on the front end blade, so that the front end blade performs high-pressure rotary motion to scrape the scales, the rear end feather wings perform the functions of removing the scales and removing dirt, and when the scale remover is in resistance and needs to be knocked backwards, the rear end blade is large in bending amplitude and large in stress surface, and the rear end blade can be transported out of the pipeline under pressure. Because the scale cleaner adopts the bearing connection, can realize the rotatory operation of high pressure in the pipeline, simultaneously the small impeller of scale cleaner rear end installation has the stress point, meets when hindering when the scale cleaner, can realize the function of moving in reverse.
Above-mentioned cleaner is in the in-service use in-process, still have following shortcoming, because the condition that partial dirt is difficult to the clearance can appear probably, can make cleaner card dead this moment to lead to its function of going backwards to be unable to realize, consequently cleaner exists thoroughly with the dead possibility of pipeline shutoff, especially block up when the pipeline interlude, can't take out smoothly this moment, need detect specific jam position, then take out after cutting off the pipeline and reconnect, the operation is particularly loaded down with trivial details, probably lead to the pipeline to scrap when serious, certain risk exists during the use, the practicality is relatively poor.
