It can be seen from above-mentioned technical proposal, in the method for the cleaning blast furnace gas pipeline that the present invention is provided, high-pressure water pipe
Shower nozzle is driven by motor-driven carrier and is walked in gas piping, meanwhile, high-pressure water pipe spray water under high pressure cleans gas piping, thus may be used
See, the method sweeps the precipitum in gas piping using high pressure water flushing, it is thus possible to effectively prevent gas piping from occurring blocking,
Or the plugging fault of gas piping can be effectively excluded, and, when cleaning blast furnace gas pipeline using the method, due to electricity
Dynamic dolly is walked in gas piping and can reach each section of part of gas piping, so without each section of part to gas piping
Perforate respectively so that cleaning works cost is lower, construction also more facilitates.
Brief description of the drawings
In order to illustrate more clearly about the embodiment of the present invention or technical scheme of the prior art, below will be to embodiment or existing
The accompanying drawing to be used needed for having technology description is briefly described, it should be apparent that, drawings in the following description are only this
Inventive embodiment, for those of ordinary skill in the art, on the premise of not paying creative work, can also basis
The accompanying drawing of offer obtains other accompanying drawings.
Fig. 1 is a kind of schematic diagram of device for cleaning blast furnace gas pipeline provided in an embodiment of the present invention.
Marked in figure：
1st, sweep；2nd, motor；3rd, wheel；4th, axletree.
Specific embodiment
In order to make it easy to understand, the invention will be further described below in conjunction with the accompanying drawings.
It is a kind of schematic diagram of device for cleaning blast furnace gas pipeline provided in an embodiment of the present invention, the device referring to Fig. 1
Including motor-driven carrier and high-pressure water pipe (not shown), wherein, motor-driven carrier is used to be walked in gas piping；High-pressure water pipe
Shower nozzle be fixedly mounted on the front end of motor-driven carrier.
It should be noted that when using, water under high pressure is provided from external water source to high-pressure water pipe, for example, generally clear by high pressure
Washing machine provides water under high pressure.
As shown in figure 1, being provided with motor 2 on the sweep 1 of motor-driven carrier, motor 2 can be 120W deceleration adjustable motors, and
By linked transmission system come axle shaft 4, so that band motor car wheel 3 advances.
In order to store a part of water on motor-driven carrier, water bag can be installed on motor-driven carrier, by one end of water bag with
Shower nozzle is connected, and the other end is connected with high-pressure water pipe.Specifically, water bag can be cylinder, and accumbency is on motor-driven carrier, water bag
Diameter be generally 150mm~160mm, for example, water bag can use a diameter of 159mm pipeline make.
In order to improve sweeping efficiency, shower nozzle can select rotary nozzle.Rotary nozzle can be with 360 degree of rotations, so that coal gas
Any position of inner-walls of duct can be rinsed.
It is the stability for keeping motor-driven carrier to advance, the wheel 3 of motor-driven carrier can select solid rubber wheel, and wheel footpath is general
