Pipeline inner wall cleaning machine

Abstract

The invention provides a pipeline inner wall cleaning machine. A wall-breaking spray head is used for carrying out high-pressure spraying along the advancing direction, reversed cleaning spray heads are arranged along the wall-breaking spray head in an annular manner, the wall-breaking spray head and the reversed cleaning spray heads are combined to carry out scale deposit cleaning, and are matched with a slag discharging structure to carry out outer discharge. The machine is characterized in that, the machine comprises a cleaning head, a discharging structure and a water conveying pipe, wherein the cleaning head is arranged on the water conveying pipe and is communicated with the water conveying pipe, a water discharging structure is arranged on the cleaning head, the discharging structure extends towards one side of the water conveying pipe, the water conveying pipe is a hose, the cleaning head is composed of the wall-breaking spray head, lateral flushing spray heads, a spray head assembly and an extension tube, the spray head assembly is of a hollow circular truncated cone structure, the two ends of the circular truncated cone are provided with connected threaded sleeves, one end of the extension tube is in threaded connection with the inside of a threaded sleeve at the large end of the circular truncated cone, the wall-breaking spray head is arranged at the other end of theextension tube, the inner channel of the wall-breaking spray head is of a variable-diameter structure, so that wall-breaking and dredging can be carried out for a thin wall formed by water scale.

Description

technical field [0001] The invention relates to a pipeline inner wall cleaning machine, which relates to a cleaning device for cleaning and discharging scale formed due to the adhesion of calcium precipitates in water in a heat transmission pipeline, and belongs to the field of pipeline engineering. In particular, it relates to a cleaning device that utilizes wall-breaking nozzles for high-pressure jetting along the forward direction and circularly distributed reverse cleaning nozzles along the broken-wall nozzles for combined scale cleaning, and cooperates with a slag discharge structure for external discharge. Background technique [0002] At present, in the process of thermal power generation, waste heat is usually used for heating, and high-pressure steam is used for heat transmission and heating. Due to water quality problems, after long-term and long-distance transmission, the inner wall of the pipe will be deposited and attached to the pipe. On the wall, and gradually...

Problems solved by technology

[0002] At present, in the process of thermal power generation, waste heat is usually used for heating, and high-pressure steam is used for heat transmission and heating. Due to water quality problems, after long-term and long-distance transmission, the inner wall of the pipe will be deposited and attached to the pipe. On the wall, and gradually grow, seriously affecting the flow section of the pipeline, serious blockage and other situations will occur, increasing the transmission resistance of the fluid in the pipeline, greatly reducing the distance of steam transmission, the existing pipeline cleaning is through a single Cleaning is done in a directional cleaning method, and the dirt after cleaning is not discharged in a concentrated manner. The residual amount after cleaning is large, and for the more stubborn scale, it needs to be washed repeatedly from two directions. It is difficult for the existing cleaning device to achieve the washing effect on both sides. , in some mechanical cleaning methods, the pipeline robot enters to clean the scale in the pipeline. Due to the mechanical structure, it is easy to get stuck and wear, which is easy to cause other problems

[0003] Publication number CN106623290A discloses a pipeline cleaning mechanism, which belongs to the technical field of cleaning equipment, and includes a driving mechanism. The output end of the driving mechanism is provided with ...
