Abstract
Description
Technical Field
[0001] This utility model belongs to the field of pipeline cleaning technology, and more specifically, it relates to a pipeline cleaning device for chemical engineering. Background Technology
[0002] In chemical production processes, pipeline transportation systems often suffer from internal wall contamination due to raw material adhesion, crystallization deposits, or chemical reaction product residues. Regular cleaning is necessary to ensure production safety and extend equipment lifespan. Chemical pipeline cleaning equipment is an auxiliary device specifically designed for cleaning chemical pipelines after use. Currently, high-pressure water flushing is the most common cleaning method, but it suffers from poor cleaning effectiveness. Simple water flushing is insufficient to effectively remove stubborn deposits from the pipe walls, especially for high-viscosity, easily solidifying chemical raw materials (such as polymers and tar-like substances), resulting in low removal efficiency and potential pipeline blockage or corrosion.

Before the cleaning block 76 enters the pipe, the position of the cleaning block 76 along the radial direction of the cleaning disc 71 is adjusted according to the pipe diameter by the sliding rod 74 and the spring 73, so that the cleaning block 76 abuts against the inner wall of the pipe, allowing the cleaning block 76 to clean pipes of different diameters. The limiting block 75 limits the sliding rod 74 to prevent it from detaching from the cleaning disc 71. The cleaning block 76 is made of polyurethane and does not damage the metal pipe wall.

The outer peripheral wall of the spray head 62 is provided with multiple spray nozzles arranged in a circumferential array.
[0056] In this embodiment, the rack 53 is a thickened rack 53.
