Cleaning device of silt-blocked pipeline

Abstract

The invention relates to a cleaning device of a silt-blocked pipeline, and belongs to the technical field of municipal engineering sewers. The cleaning device is characterized in that a spraying head shell is conical, a scraper and a high-pressure water spray hole are axially arranged on the outside surface of the spraying head shell, and a connection hole is formed in the center of a closing plate at the bottom of the spraying head shell; one end of a scarfer is provided with an outward convex step, the outside diameter of the outward convex step is larger than the inside diameter of the connection hole in the center of the closing plate, and the outward convex step is of a tee pipe shape; and one end, provided with the outward convex step, of the scarfer is placed in the inner cavity of the spraying head shell, and the other end of the scarfer is connected with a high-pressure water hose arranged outside the spraying head shell by a connection hole. The cleaning device has the benefits that the structure is simple, parts and components are few, and the use is convenient; the exposed part of the scarfer in the connection hole of the closing plate is connected and fastened with the high-pressure water hose; and because the spray hole direction has an alpha angle with the radial line direction of the spraying head, and inclines toward the rear part of the spraying head, the spraying head rotates and drills forwards simultaneously by virtue of reactive thrust of the high-pressure water spraying, the inner wall of the pipeline is cleaned through scraping and brushing due to the rotation of the scraper, and the pipeline is dredged by the forward drilling of the spraying head.

Description

technical field [0001] The invention belongs to the technical field of municipal engineering sewers, and relates to a cleaning device and a cleaning method for clogged pipelines, which are suitable for non-pressure, full-flow or half-flow pipelines in municipal facilities such as sewers, sewage pipes, and canal pipes for rural irrigation. Unclog and wash. Background technique [0002] In municipal facilities, sewers, sewage pipes, and agricultural irrigation canal pipes, etc., often have mud and dirt sticking and silting on the inner wall of the pipes after long-term use, making the passage of the pipes gradually smaller or even blocked. It is very laborious to clean these pipes . At present, there are various types of cleaning tools used for pipeline cleaning, including mechanical pressure cleaning, pipeline rotation cleaning, cleaning climbing car, robot cleaning and other devices, and the combination of wheel brush and scraper with strong cleaning ability Pipeline clean...
