Detailed description of the invention
In order to deepen the understanding of the present invention, be described in further detail the present invention below in conjunction with drawings and Examples, this embodiment, only for explaining the present invention, not forming protection scope of the present invention and limiting.
Shown in Fig. 1, the present invention is a kind of elbow internal wall derusting device, described derusting device comprises the chassis 1 placing the movement on guide rail of several bend pipes 3, be placed on chassis by needing the bend pipe carrying out inwall rust cleaning, chassis controls mobile by PLC, the time of motion and speed, described chassis 1 is provided with the fixture that array fixes described bend pipe 3, often organizing described fixture comprises for the fixing pressure ring 2 of bend pipe insertion, the clasp 4 of fixing described bend pipe is provided with in the centre of every two described pressure ring 2 sides, when placing bend pipe, the two-port of bend pipe is inserted in pressure ring, and then by clasp 4 by fixed for the bottom of bend pipe, avoid in the process of rust cleaning because the extraneous factors such as impulsive force cause bend pipe to move, the thing that dropping etc. affects bending quality occurs, the sand-blasting gun that triangle support frame 5 supports is provided with in the side of described chassis 1, metal tube 7 is arranged with outside the rifle mouth 6 of described sand-blasting gun, one end of described sand-blasting gun is connected with the abrasive blast equipment 8 placing river sand, river sand that abrasive blast equipment 8 is placed is through that abundant bake drying crosses, and river sand is crossed after 4-10 eye mesh screen filters and just can be used, if river water-containing rate is high, the effect then eliminated rust does not reach, still rusty stain can be there is in some position, through experiment repeatedly, river sand is carried out air-dry drying, sand is tiny, adopt the operating procedure of rotoblast again, can be thoroughly clean by inner wall cleaning, described rifle mouth 6 is 300-500mm with the distance of bend pipe 3 mouth of pipe, ensure that the nozzle position of bend pipe also can eliminate rust, sandblasting dead angle can not be there is, sandblasting is effective, the diameter that described rifle mouth 6 exports is 8-10mm, original rifle mouth is changed, be applicable to the discharging of river sand, described triangle support frame 5 is provided with and drives rifle mouth 6 to do clockwise or the motor be rotated counterclockwise, motor sets program, rifle mouth 6 is driven to carry out turning clockwise or being rotated counterclockwise or a rotation mode combined along an anti-phase, baffle plate 9 is also provided with in the side of described chassis 1, the effect of baffle plate avoids meeting accident, inclination flitch 10 is provided with between the below and described chassis 1 of described baffle plate 9, the hopper 11 borrowing material is had at the envisaged underneath of described inclination flitch 10, to be entered in hopper 11 by inclination flitch 10 from the mouth of pipe of bend pipe sand out and dust and recycle, free from environmental pollution, ensure the health of working environment.
The method for cleaning of the bend pipe derusting device of apparatus of the present invention comprises the steps:
(1) dried up by the water residual through water pressure test elbow internal wall, bend pipe needs to carry out hydraulic pressure test to the pressure of pipeline at rust cleaning money, therefore must dry up by the water residual to elbow internal wall before elbow internal wall cleaning, ensures the aridity of elbow internal wall;
(2) bend pipe after above-mentioned oven dry is placed on chassis fixes, keep the mouth of pipe direction of all bend pipes consistent, and chassis is driven into relatively airtight space, the height of chassis is probably in the effect of 0.5-0.9 rice, such height is applicable to operation, and pipeline rust cleaning is carried out in relatively airtight space, sand can be avoided like this to fly out pipeline and meeting accident, ensure safety;
(3) metal sleeve is set in the outside of the rifle mouth of the sand-blasting gun that the abrasive blast equipment of putting into river sand with one is connected, the diameter of described rifle mouth is 8-10mm, change the size of original rifle mouth, make it the injection of applicable river sand, abrasive blast equipment compressed air input pressure is 1-2MPa, through debugging repeatedly, the pressure of the compressed air input of adjustment needed for sandblasting, this pressure range achieves desirable rust cleaning effect, and sand-blasting gun is placed on a triangle support frame, be fully dry river sand in abrasive blast equipment, and described river sand uses after crossing 4-10 eye mesh screen, in the process selecting river sand, if the aridity of river sand is inadequate, the effect of rust cleaning is general, still rusty stain can be there is in some position, and after air-dry drying and to cross the river sand of 4-10 eye mesh screen tiny, by the operating procedure of rotoblast, can be thoroughly clean by inner wall cleaning, during sandblasting, described rifle mouth does counterclockwise or clockwise rotation, sand-blasting gun is placed on one and cries on light triangle support frame, the rotary motion of rifle mouth can by driven by motor that A-frame is arranged clockwise or be rotated counterclockwise,
(4) from one end of bend pipe, river sand blasting is entered in bend pipe, blast time 1.5-1 minute, the distance of the mouth of pipe of described rifle mouth distance bend pipe is 300-500mm, retain a segment distance, the rusty stain of bend pipe nozzle position also can be removed, sandblasting is effective, has placement sand to spray the baffle plate of hurting sb.'s feelings at the port of export of bend pipe, places sand and causes unexpected injury from one end ejection of bend pipe;
(5) after sandblasting completes, the residual river sand of sponge cleaning and dust are blown to elbow internal wall, moved by PLC programme-control chassis, after sandblasting completes, chassis moves forward, and then rests on the position of blowing sponge, blows sponge to bend pipe, two ports of every root bend pipe blow sponge respectively once respectively, and cleaning remains in fool and the dust of elbow internal wall;
(6) by endoscopy inner surface of tube, check whether rusty stain is removed clean completely.
Through production practices, the technique of this cleaning elbow internal wall rusty stain can complete the rust cleaning of product smoothly, and through inspection, inside pipe wall quality meets the technical standards requirement.
