Abstract

The invention belongs to the technical field of derusting and cleaning conducted before anti-corrosion coating is conducted the inner wall of a steel pipe and particularly relates to a wire brush derusting method. According to the wire brush derusting method, the purposes of derusting and generation of anchor patterns are achieved by knocking the inner wall of the steel pipe with a steel wire of a wire brush. The wire brush derusting method specifically comprises the steps that the wire brush which rotates around the axis of the wire brush is adopted, elastic deformation happens to the steel wire of the wire brush through impediment of a wire brush blocking shaft, after the steel wire subjected to elastic deformation overcomes the impediment of the wire brush, the inner wall of a pipeline to be derusted is knocked by the steel wire rapidly so that rust can be stripped, and anchor patterns are generated on the inner wall of the steel pipeline through knocking at the same time. A derusting device is moved along the axis of the steel pipeline, the wire brush makes superimposed linear movement around the circumference of the axis of the steel pipeline, and then rust on the inner wall of the whole pipeline is removed.

Description

A kind of Novel wire brush derusting method

Technical field

The invention belongs to the rust cleaning Removal Technology field before steel pipe inner wall anticorrosive coating, be specifically related to a kind of brush cleaning method.

Technical background

Current steel conduit inwall rust cleaning has two kinds of techniques and one to be adopt ball blast (sand) to impact steel conduit inner surface, and another kind adopts wire brush to carry out brushing method to steel conduit inner surface.Not only adopt the process of ball blast (sand) that steel pipe internal-surface can be made to eliminate rust but also anchor line can be impacted and adopt the process of wire brush can only remove steel pipe inner wall corrosion can not to obtain anchor line.And its inner surface can be brushed brighter and brighter.Do not have the steel pipe inner wall of anchor line can be beneficial to the bonding of steel pipe anticorrosion paint.The inner surface of light more affects the anticorrosion bond effect of coating.The invention provides a kind of new derusting method, ball blast can not be adopted to impact steel tube surface and adopt wire brush impact steel tube surface result from the same rust cleaning effect of ball blast (sand) and impact out the anchor line being conducive to anticorrosive paint bonding.Adopt the rust cleaning of wire brush impact steel duct to simplify technique without shot (sand), especially for adopt traditional impeller blasting technique to process small-bore pipeline rust cleaning, there is significantly outstanding advantage.

Summary of the invention

For the problems referred to above, the invention provides a kind of Novel wire brush derusting method, reach rust cleaning by the steel wire impact steel pipe inner wall of wire brush and produce anchor line dual purpose.

The present invention is achieved in that a kind of Novel wire brush derusting method, it is characterized in that comprising the following steps:

1) provide treat rust cleaning pipeline (1), steel conduit to be eliminated rust is fixed, carrying out rust cleaning prepare;

2) rust removalling equipment to be inserted in pipeline and to make wire brush (2) be adjacent to pipeline (1) inwall;

3) wire brush (2) rotates around its axis, and wire brush gear shaft (5) hinders wire brush to rotate, and makes the steel wire (3) of wire brush (2) produce elastic deformation;

4) after the steel wire (3) of generation elastic deformation overcomes the obstruction of wire brush gear shaft (5), elastic potential energy is released, steel wire (3) flying hit waits pipeline (1) inwall that eliminates rust, this flying hit makes corrosion be peeled off, on steel conduit inwall, impact out the tiny pit being conducive to anticorrosive paint bonding, i.e. anchor line simultaneously;

5) steel wire (3) successively rotated continuously impacts steel conduit (1) inwall, eliminates rust to steel conduit inwall;

6) axis of wire brush (2) around the line shaft (7) concentric with steel conduit (1) under wire brush pivoted arm (4) drives moves in a circle, and removes the corrosion of steel conduit (1) circumferential band scope;

7) move rust removalling equipment along steel conduit (1) axis, wire brush (2), around steel conduit circumference motion superposition Linear-moving, removes the corrosion of whole inner-walls of duct.

A kind of Novel wire brush derusting method of the present invention, is characterized in that wire brush rotating shaft (5) is linked together by fixed head (6) and wire brush pivoted arm (4).

Detailed description of the invention

Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples for illustration of invention, but are not used for limiting the scope of the invention.

As Figure 1-3, a kind of Novel wire brush derusting method, comprises the following steps:

1) provide wait eliminate rust pipeline 1, steel conduit to be eliminated rust is fixed, carrying out rust cleaning prepare;

2) rust removalling equipment to be inserted in pipeline and to make wire brush 2 be adjacent to pipeline 1 inwall;

3) wire brush 2 rotates around its axis, and wire brush gear shaft 5 hinders wire brush to rotate, and makes the steel wire 3 of wire brush 2 produce elastic deformation;

4) after the steel wire 3 of generation elastic deformation overcomes the obstruction of wire brush gear shaft 5, elastic potential energy is released, steel wire 3 flying hit treats rust cleaning pipeline 1 inwall, this flying hit makes corrosion be peeled off, on steel conduit inwall, impact out the tiny pit being conducive to anticorrosive paint bonding, i.e. anchor line simultaneously;

5) steel wire 3 successively rotated continuously impacts steel conduit 1 inwall, eliminates rust to steel conduit inwall;

6) axis of wire brush 2 around the line shaft 7 concentric with steel conduit 1 under wire brush pivoted arm 4 drives moves in a circle, and removes the corrosion of steel conduit 1 circumferential band scope;

7) move rust removalling equipment along steel conduit 1 axis, wire brush 2, around steel conduit circumference motion superposition Linear-moving, removes the corrosion of whole inner-walls of duct.

A kind of Novel wire brush derusting method of the present invention, wherein wire brush rotating shaft 5 is fixed together by fixed head 6 and wire brush pivoted arm 4, moves together with wire brush pivoted arm 5.
