Abstract

The invention relates to a pipeline cleaning device, in particular to a cleaning device for cleaning the inner wall of a vertical oil tube. The cleaning device comprises a hole ejector and an ejectionsleeve, wherein the ejection sleeve is used for ejecting the hole ejector, the hole ejector is located in the ejection sleeve, the ejection sleeve comprises a clamping guide sleeve and an ejection switch which can be triggered, the ejection switch is installed at the bottom of the clamping guide sleeve, the top end of the ejection switch is connected with a connecting rod, a blocking piece on thetop end of the connecting rod is connected with a connecting shaft of the hole ejector, a compressed ejection spring sleeves the connecting rod on the bottom end of the blocking piece, the bottom endof the ejection switch is connected with an ejector rod, the ejection switch comprises a cylinder, a steel ball and a spring, the steel ball is located in a round cavity of the cylinder, and the spring is arranged on one end of the steel ball. According to the device, the hole ejector can be put at the bottom of a well by virtue of the ejection sleeve and is ejected into the oil tube, and then the hole ejector is pushed out from the bottom of the well by backwashing high-pressure liquid, so that the hole ejection cleaning and descaling of the inner wall of the vertical oil tube are realized,and the descaling effect is good.

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...
