Abstract

The invention relates to a pipeline cleaning device, in particular to a cleaning device for cleaning the inner wall of a vertical oil pipe, which includes a cavitation jet and an ejection sleeve for ejecting the cavitation jet. Inside, the ejection sleeve includes a snap-in guide sleeve and an ejection switch that can be triggered. The ejection switch is installed at the bottom of the snap-in guide sleeve. The top of the ejection switch is connected to the connecting rod. Connection, the connecting rod at the bottom end of the blocking plate is covered with a compressed ejection spring, and the bottom end of the ejection switch is connected with the ejector rod; the ejection switch includes a cylinder, a steel ball and a spring, the steel ball is located in the circular cavity of the cylinder, and a spring is provided at one end of the steel ball. The device can put the cavitation ejector into the bottom of the well through the ejection sleeve and eject it into the oil pipe, and then push the cavitation ejector from the bottom of the well through the backwash high-pressure fluid to realize the cavitation of the inner wall of the opposite oil pipe Jet cleaning and descaling, good descaling effect.

Description

technical field [0001] The invention relates to a pipeline cleaning device, in particular to a cleaning device for cleaning the inner wall of a vertical oil pipe. Background technique [0002] Oil pipes used for a long time have serious fouling, and if they are not cleaned and descaled, production efficiency will be affected. At present, the method of cleaning the inner wall of the vertical oil pipe mainly adopts chemical cleaning and descaling. Chemical cleaning can easily cause damage to the pipe wall of the oil pipe, reduce the service life of the oil pipe, increase the maintenance cost, and the cleaning effect is poor. However, the existing physical cleaning method can only clean and descale the horizontal pipeline. The commonly used physical cleaning and descaling method mainly uses a cavitation jet for cleaning and descaling. Ejectors and other injectors that utilize the principle of cavitation, the above-mentioned various cavitation jets have good cleaning and descal...
