Intermittent cleaner

Abstract

The invention discloses an intermittent cleaner for crude oil pipeline cleaning. The intermittent cleaner includes a scrapper, a turbine, an turbine, a power supply, and a power supply control module; the scrapper includes a scrapper core shaft and a plurality of hollow frames sleeving the scrapper core shaft; a plurality of scrapping blades are arranged on outer edges of the hollow frame; the turbine includes a rotor bottom plate and turbine vanes, the rotor bottom plate has a central opening, and a turbine rotor inner ring is inserted into the opening and is fixedly connected to the rotor bottom plate; the electromagnet includes a stator inner ring and an electromagnet outer ring, a tail end of the stator inner ring is fixedly connected to the power supply and the power supply control module; the scrapper core shaft and the turbine rotor are coaxial, and fixedly connected; and the turbine rotor inner ring is in matching connection with the stator inner ring through a bearing. The cleaner can use the impact force of fluid in a pipeline to regularly and automatically scrap wax in the pipeline, and can effectively prevent pipeline blockage.

Description

technical field [0001] The invention belongs to the field of pigs for crude oil pipelines, and in particular relates to an intermittent pig that can avoid jamming caused by wax plugs formed due to severe wax deposition on pipe walls during the pigging process. Background technique [0002] During the operation of waxy crude oil pipelines, wax deposits will inevitably occur, which will reduce the transportation capacity, and may even lead to the stoppage of condensation pipes. The wide application of pigging technology has solved this problem to a certain extent. In order to meet the needs of the industry, there are many different types of pigs, which basically rely on the pressure of the conveying medium to push the pigs forward, and enhance the pigging effect through the sealing of the cup or the ball. In the above-mentioned traditional pigging method, the running speed of the pig is equivalent to the speed of the medium, resulting in too fast pigging speed, and the wax and...

Problems solved by technology

When the above-mentioned pigs are in operation, due to the small and closed flow cross-section, the residual impurities under the washing will easily cause the blockage of the spiral flow channel or the diversion hole, which will affect the normal operation of the pig
