Nozzle and cleaning device

Abstract

The invention relates to a nozzle and a cleaning device. The nozzle comprises a sleeve, a spindle, a nozzle body, a direct jetting nozzle and an inclined jetting nozzle. The sleeve is provided with a first opening and a second opening, and the first opening can be used for inputting cleaner fluid. One end of the spindle extends into the sleeve, and the other end is exposed from the second opening; the spindle is provided with a channel communicated with the first opening, and the channel allows the cleaner fluid to pass. The rear end of the nozzle body is connected to one end of the spindle outside the second opening. The direct jetting nozzle is mounted on the nozzle body and is communicated with the channel; the direct jetting nozzle can jet the cleaner fluid out to form a jet flow towards the front of the nozzle body. The inclined jetting nozzle is mounted on the nozzle body and is communicated with the channel; the inclined jetting nozzle can jet the cleaner fluid out to form a jet flow towards the inner wall of the pipeline so as to push the nozzle body to move forward and drive the nozzle body to rotate around the spindle. The nozzle has the advantages that the nozzle of the cleaning device can move in the pipeline automatically and can clean the inner wall of the pipeline overall evenly, and pipeline cleaning quality is improved.

Description

technical field [0001] The invention relates to a spray head and a cleaning device. Background technique [0002] At present, in the oil pipe repair process, the oil pipe is mostly cleaned by chemical cleaning. In this method, the oil pipe is firstly washed with alkali, then pickled, and then the oil pipe is neutralized. For the blocked oil pipe, it must be pretreated with drill pipe first, so as to ensure that the cleaning operation is carried out normally. The chemical cleaning method is simple in process, but its cleaning quality is easily affected by the dirt on the inner and outer walls of the oil pipe, human and environmental factors. [0003] Another cleaning solution is high-pressure water jet cleaning. Its main features are easy operation and high efficiency. Ultra-high pressure water jet can remove hard and difficult scale. Compared with chemical cleaning, it does not pollute the environment, does not corrode the cleaning object, and has high cleaning efficiency. ...

AI Technical Summary

Problems solved by technology

[0004] However, the current high-pressure water jet cleaning solution also has certain problems, that is, it is difficult for the high-pressure nozzle to clean the inner wall of the pipeline uniformly, resulting in some areas not being cleaned or the cleaning effect is poor

[0005] It can be seen that the above-mentioned existing high-pressure water jet solution obviously still has inconvenience and defects in structure and use, and needs to be further improved urgently.
