Description

Efficient cleaning process for large-scale conveying pipeline

Technical Field

The invention relates to the technical field of conveying pipeline processing, in particular to an efficient cleaning process for a large-scale conveying pipeline.

Background

The conveying pipeline is a pipeline specially used for conveying liquid and gas materials, is called pipeline transportation by adopting a pipeline conveying material method, is a special transportation mode for conveying petroleum, coal and chemical products to the market from a production place, is a special component part for trunk line transportation in a uniform transportation network, is a pipeline made of materials suitable for different use occasions, is widely applied to a process pipeline of a metallurgical mine, a tailing conveying pipeline, a coal washing and coal dressing plant process pipeline, a coal gangue discharge conveying pipeline and the conveying of remote finished coal slurry, the large-scale conveying pipeline is widely used, a multi-pipeline finished product is required to be cleaned in the production process of the large-scale conveying pipeline, the original cleaning mode is that the pipeline is directly washed through a flushing pipe or is intensively lifted to a cleaning pool through a crane to be soaked and cleaned, and the cleaning method is complicated.

Referring to chinese patent publication No. CN111468483A, a push-type large-scale pipe internal cleaning device is disclosed as reference patent 1, the whole vehicle frame can be driven to move by pushing the push handle, the vehicle frame drives the first magnet to move for a moment through the connecting rod and the mounting frame, the second magnet can drive the cleaning roller to move, the cleaning roller can clean the inside of the pipeline in the moving process, the operation is simple, the cleaning efficiency is high, the moving wheel can rotate along the inner side wall of the large pipeline by the movement of the cleaning mechanism to drive the cleaning roller to move to rotate to clean the pipeline, the cam can drive the installation rod to move left and right through the connecting ball, the installation rod can drive the cleaning roller to move left and right through the connecting block, the cleaning roller can move left and right at intervals when rotating, the same position inside the pipeline can be cleaned for many times, the cleaning is more thorough, and the cleaning effect is better.

Refer to chinese patent publication CN 107537833A's a large-scale pipeline belt cleaning device, mark as reference patent 2, this patent passes through the motor belt and drives the folding rod, and the folding rod is folding to drive the rotation type cleaning brush and is the downstream, and the rotation axis motion of rotation type cleaning brush central part drives the pivot circumferential direction of both sides, and installs first scrubbing portion and the second scrubbing portion in the pivot and can use the pivot to realize the rotation as the rotation center to can realize the cleanness to the pipeline inner wall.

A comprehensive analysis of the above referenced patents can yield the following drawbacks:

1) refer to patent 1 and refer to patent 2 and only can wash the inside of single pipeline, wash still not thoroughly, can not realize wasing large-scale pipeline's inside and outside simultaneously, accomplish the back to the inside washing of pipeline, still need wash the outside of pipeline in addition, increased cleaning personnel's work burden, can't reach the purpose of going on simultaneously together with the inside and outside washing of pipeline is concentrated to the washing work of giving cleaning personnel brings very big inconvenience.

2) Refer to patent 1 and refer to patent 2 and can not realize large batch automatic washing, once wash the completion back to referring to patent 1, need the cleaning personnel to promote whole cleaning equipment to carry out the washing of next pipeline, waste time and energy and the pipe diameter of pipeline is not of uniform size, refer to patent 1's application range and comparatively limit, be unfavorable for using widely, refer to patent 2 and wash a pipeline after, need stand next pipeline, the process of making the pipeline stand itself is just very loaded down with trivial details, especially to the great steel material pipeline of pipe diameter, and is large in size, the quality is heavy, it is very hard to stand the pipeline, consequently, two patents of referring to can not realize automatic washing, can't reach not only fast but also the efficient and carry out abluent mesh to large-scale pipeline.

3) Refer to patent 1's washing structure comparatively complicated, realize wasing the characteristic structure at pipeline inside motion through adopting a large amount of transmission structures, and insert the pipeline with a large amount of transmission structures, high in production cost, very be unfavorable for using widely, and refer to patent 2 and adopt simple washing structure to wash the pipeline, nevertheless have certain use restriction, when the length of highly surpassing the washing structure of pipeline, obviously can not carry out the inside whole washing of pipeline, and refer to patent 2's washing structure and need follow in down inserting the pipeline, when the pipeline height is higher, need be equipped with the great elevating system of high stroke and just can normal use, therefore such cleaning equipment is bulky, it is higher to require the washing place.
