Abstract

The utility model discloses an impurities purging and removing device for an internal steel pipe. A steel pipe is disposed on a rotating roller, and one end of the steel pipe is disposed in an anti-splashing bin. A purging gun is sent in the steel pipe at a uniform speed through a gun-delivering dolly. A high pressure air blower disposed on the gun-delivering dolly is connected to the purging gun. A purging gun supporting wheel is fixed on the ground. A steel emery (steel shots) recovery case is disposed at the bottom of the anti-splashing bin. A filtering recovery device is connected to the anti-splashing bin through an air pipe. A dust-collecting box is disposed at the bottom of the filtering recovery device. The impurities purging and removing device is advantageous in that an air supply system of a high pressure air blower is adopted, and an anti-splashing bin and a filtering recovery device are additionally arranged, and thereby steel emery (steel shots) and dust removed during the purging process will not splash or scatter in the air; steel emery (steel shots) will be recovered in the steel emery (steel shots) recovery case; fine dust is filtered through a filtering device, dust is collected in a dust-collecting box, and clean air is discharged; the automatization degree is high, the operation is convenient, the safety is high and environment is protected.

Description

Impurity purges scavenge unit in the steel pipe pipe

Technical field

The utility model relates to a kind of steel pipe inwall impurity purging and goes out equipment clearly, belongs to impurity purging scavenge unit in the steel pipe pipe.

Background technology

The steel pipe inside pipe wall carry out anticorrosion before; Impurity is adhered in the corrosion of needs removing inside pipe wall face etc.; General sandblast or the impeller blasting mode of adopting impacts removing, and adopts high-power retracting device to carry out the recovery of steel sand (ball) and removal of contamination, but because the restriction of reclaimer self; The interior impurity of pipe can't not have safety to be cleaned out, and blow device purges cleaning in the pipe so must adopt.

The interior cleaning plant that purges of present stage pipe mainly adopts compressed air system, and the air outlet of compressor is connected with small-caliber steel pipe through flexible hose, and steel pipe is sent in the pipe through manual work; Start compressed air simultaneously and clear up, or adopt travelling car to send into small-caliber steel pipe in the pipe and clean, the steel pipe other end mouth of pipe or do not adopt any retracting device; Appoint that impurity splashes in the pipe in air, or adopt small-power deduster such as cloth bag, though certain recovering effect is arranged; But also exist partial impurities in air, to splash, and the not process filtration of the gas of retracting device discharge, institute has impurity; Under the effect of blower fan, be diffused into farther distance.So above-mentioned blow device is very serious to the pollution of environment.And the employing compressed air system in the purge, needs high-power compressor, has wasted electric power resource, or because of open circuit purges, has influence on the stable gas pressure of whole air supply system.

Summary of the invention

To the weak point of impurity purging scavenge unit in the existing steel pipe pipe, the purpose of the utility model is to provide impurity purging scavenge unit in a kind of steel pipe pipe.This device is easy to operate, reduces manual work, and is rational in infrastructure, and production efficiency is high, reduces resource consumption, and impurity purges scavenge unit in the steel pipe pipe of environmental protection.

The utility model purpose adopts following technical scheme to realize:

Impurity purges scavenge unit in a kind of steel pipe pipe, mainly by high pressure positive blower, send rifle dolly, support wheel, swing roller, purging rifle, steel pipe, the anti-storehouse of splashing, steel sand, ball collection box, travelling car, filtering retracting device, dirt collection case to form.Steel pipe is placed on the swing roller; The one of which end is inserted the anti-storehouse of splashing, and purges rifle and at the uniform velocity sends into steel duct through sending the rifle dolly, is installed in the high pressure positive blower that send on the rifle dolly and is connected with the purging rifle; Purging rifle support wheel and ground fixes; Steel sand (ball) collection box is installed in the anti-bottom, storehouse of splashing, and the filtering retracting device is connected with the anti-storehouse of splashing through airduct, and the dirt collection case is installed in filtering retracting device bottom.

The utility model and prior art be advantage relatively:

1, adopt the high pressure positive blower supply air system, cancelled traditional compressor air-supply, high pressure positive blower can be installed on the travelling car, has reduced the pipeline laying of compressor assembly, has reduced power consumption, has guaranteed that the blast of compressor supply air system is stable.

2, adopted the filtering retracting device, and be provided with the impurity collection box, improved the organic efficiency of minute impurities and the cleanliness factor of air discharging, thereby reduced environmental pollution.

3, anti-splash storehouse and the steel sand, the ball collection box that adopt not only can prevent splashing of steel sand, ball or dust, and can recycle steel sand, ball, avoid the waste of steel sand, ball material.

Description of drawings

Fig. 1 is the utility model structural representation.

Among the figure: 1-high pressure positive blower, 2-send rifle dolly, 3-support wheel, 4-swing roller, 5-to purge rifle, 6-steel pipe, 7-anti-splash storehouse, 8-steel sand, ball collection box, 9-travelling car, 10-filtering retracting device, 11-dirt collection case.

The specific embodiment

As shown in Figure 1; Impurity purges scavenge unit in a kind of steel pipe pipe, mainly by high pressure positive blower 1, send rifle dolly 2, support wheel 3, swing roller 4, purge rifle 5, steel pipe 6, anti-splash storehouse 7, steel sand, ball collection box 8, travelling car 9, filtering retracting device 10 and dirt collection case 11 form.Steel pipe 6 is placed on the swing roller 4; The one of which end is inserted the anti-storehouse 7 of splashing, and purges the inside of rifle 5 through sending rifle dolly 2 at the uniform velocity to send into steel pipe 6, is installed in the high pressure positive blower 1 that send on the rifle dolly 2 and is connected with purging rifle 5; Purging rifle support wheel 3 fixes with ground; Steel sand, ball collection box 8 are installed in the bottom in the anti-storehouse 7 of splashing, and filtering retracting device 10 is connected with the anti-storehouse 7 of splashing through airduct, and dirt collection case 11 is installed in the bottom of filtering retracting device 10.

Remove the steel pipe 6 of inside pipe wall rusty scale through throwing (spray) ball, be placed on the swing roller 4, start swing roller 4 and make at the uniform velocity spinning of steel pipe 6, start travelling car 9 simultaneously; Make steel pipe 6 one ends insert in the anti-storehouse 7 of splashing, travelling car 9 is out of service, when starting filtering retracting device 10, starts high pressure positive blower 1; Unlatching send rifle dolly 2 to make to purge rifles 5 at the uniform velocity mobile in steel pipe 6, progressively removes in the pipe and leaves over steel sand, ball or dust, stretches into anti-when splashing storehouse 7 when purging rifle 5 rifle heads; Stop to send rifle dolly 2 reaches and mobile backward, purging rifle 5 is at the uniform velocity withdrawed from the steel pipe 6, withdraw from the steel pipe 6 when purging rifle 5; Stop high pressure positive blower 1 running, stop 10 runnings of filtering retracting device simultaneously, start travelling car 9 and withdraw from steel pipe 6 pipe ends; Send rifle dolly 3 and travelling car 9 to get back to original position, stop two trolley travellings, purge and accomplish.After regularly sieving, steel sand, the ball of collecting in steel sand, the ball collection box 8 mix use, dust periodic cleanings in the dirt collection case 11 with former steel sand, ball.
