Abstract

The utility model relates to a pipeline ash removal machine which belongs to the technical field of pipeline cleaning equipment and aims at providing a device during the application of which pipelines do not need cutting off and dirt deposited in the pipelines can be quickly cleaned. The utility model adopts the technical scheme that the pipeline ash removal machine is composed of a driving machine, a driven machine, working chains, a steel hook and a scratch board, wherein the driving machine comprises a speed reducer, a transmission shaft and a driving sprocket; one end of the transmission shaft is connected with an output axle hole of the electromechanical speed reducer provided with a bevel wheel, a worm wheel and a worm; the driving sprocket is installed on the other end of the transmission shaft, the driven machine comprises a driven shaft and a driven sprocket, the working chains are installed between the driving sprocket and the driven sprocket, and the steel hook and the scrape board are hung on the working chains. When the pipeline ash removal machine works, coal gas transport pipelines do not need cutting off, the driving machine drives the working chains to clean dirt in the pipelines by the steel hook and the scrape board, examination and repair time and cost can be reduced by more than 90%, and the labor intensity of workers is greatly reduced.

Description

The pipeline dust removing machine

Technical field

The utility model relates to a kind of device of removing the gas piping dust stratification, belongs to the duct cleaning equipment technical field.

Background technology

In smelter, coke-stove gas and blast furnace gas are a kind of important gaseous state energy fuels as the byproduct in producing.The conveying of coal gas mainly relies on pipeline to carry out, though purifying and dedusting equipment is arranged in course of conveying, but still also have a large amount of dust, sulphur, naphthalene, phenols dirt in the coal gas, because coal gas contains moisture, humidity is in saturation state simultaneously, various dirt particles in the coal gas are easy to stick on the gas piping wall, deposition is got off, and causes the effective aperture of gas piping to diminish, and the resistance that coal gas moves in pipeline increases, the gas compressor load increases, and electric energy loss is obviously risen.Therefore, after the dirt of gas piping deposits to a certain degree, must remove operation to the pipeline that is stopped up.At present, the method of removing deposit dirt in the gas pipeline in smelter is that a section is cut open with pipeline, welds behind the tamper of the clean the inside of removing again, and this method need be employed lot of manpower and material resources, engineering time is long, and is very big to the influence of producing.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of pipeline dust removing machine that pipeline need not be cut off, also can remove the dirt that deposits in the pipeline fast.

The technical scheme that solves the problems of the technologies described above is:

A kind of pipeline dust removing machine, it is made up of active machine, driven machine, work chain, steel hook and scraper plate, initiatively machine comprises reductor, power transmission shaft, drive sprocket, one end of power transmission shaft is connected with the output shaft hole of reductor, and drive sprocket is installed in the other end of power transmission shaft, and driven machine comprises driven shaft and driven sprocket, driven sprocket is installed on the driven shaft, the work chain is installed between drive sprocket and the driven sprocket, on steel hook and the scraper plate hook is arranged, and hook is complementary with the perforation hole of work chain.

Above-mentioned pipeline dust removing machine has chain tensioning mechanism on driven sprocket.

The pipeline dust removing machine of this structure, needn't cut off gas pipeline at work, by active machine drive work chain steel hook and scraper plate ducted dirt removal, can all reduce repair time and maintenance disbursement more than 90%, also alleviated working strength of workers greatly, owing to saved the repair time, reduce the off-time simultaneously, significantly improved the economic benefit that enterprise produces.

Description of drawings

Fig. 1 is a mounting structure schematic diagram of the present utility model;

Fig. 2 is the vertical view of Fig. 1.

Mark is as follows among the figure: reductor 1, power transmission shaft 2, drive sprocket 3, work chain 4, driven shaft 5, driven sprocket 6, steel hook 7, scraper plate 8, workbench 9, gas pipeline 10, pipeline working hole 11, deposit dirt 12

The specific embodiment

As we can see from the figure, the pipeline dust removing machine is made up of active machine, driven machine, work chain 4, steel hook 7 and scraper plate 8, initiatively machine comprises electromechanical helical gear worm-gear speed reducer 1, power transmission shaft 2, drive sprocket 3, initiatively the effect of machine part is that drive work chain 4 moves in pipeline, to remove the dirt of deposition.Driven machine comprises driven shaft 5 and driven sprocket 6, and the effect of driven machine part is the rotation direction that support performance chain 4 rotated and changed work chain 4, forms closed rotation loop.On steel hook 7 and the scraper plate 8 hook is arranged, can hang in the perforation hole of work chain 4, also can take at any time.When driven by motor worm-gear speed reducer 1 and power transmission shaft 2 rotations, drive sprocket 3 also rotates thereupon, drive work chain 4 moves forward, and the steel hook 7 and the scraper plate 8 that hang on the work chain 4 can become flexible the deposit dirt in the gas pipeline 10, sweep, and take opening part to and go out clearly.In order to prevent that work chain 4 is lax at work, has chain tensioning mechanism on driven sprocket 6.

The utility model adopts electromechanical helical gear worm-gear speed reducer, has compact conformation, little, the lightweight advantage of volume, and motor is 4 grades of 0.75KW three phase squirrel cages, and output shaft per minute 26 changes tractive force 7900 newton; The steel hook is a ship anchor shape, is convenient to loose tamper; Scraper plate has plurality of specifications, can select for use.

The utility model is when work, need not cut off gas pipeline, (decide as long as below the gas pipeline of preparing cleaning, keep at a certain distance away on field condition, as 30 meters) building platform in advance, pipeline is stopped the supple of gas or steam the qualified back of displacement preceding, the upper and lower of the pipeline of back workbench position is respectively severed one 1 meter long semicircle working hole, before the active machine of pipeline dust removing machine and driven machine directly be erected at respectively, on the back working hole, deliver to another working hole with the defeated pipe device chain of will working from a working hole, be hung on the turning gear of drive sprocket and driven sprocket, just can have begun operation after adjusting the position of work chain and tensity.During operation, forward and backward working hole respectively has 1 operating personnel, the personnel of driven machine one end hang over cleaning devices such as steel hook, scraper plate on the work chain earlier, the operating personnel of notice active machine one end open initiatively machine then, and whenever be spaced a distance (as about 6 meters) stop machine, the cleaning device of seting out a time, such end is hung, the other end is plucked, and constantly circulation repeats, and the most ducted deposit dirt is removed clean.

Adopt this pipeline dust removing machine, can improve the operating rate of removing the deposit dirt in the gas pipeline greatly.With 300 meters long, the gas piping of diameter 500mm is an example: if adopt in the past whole to cut off to hang be discharged on the ground cleaning clean after, the restorable construction method of lifting welding needs 35 people to work 20 days again; And adopt this pipeline dust removing machine, only need 15 people to work 3 days, and, also can not influence road traffic without big machineries such as cranes.Adopt this construction method, operator only need the to set out instrument of removing contamination and adjustment, install machinery at the working hole place, labour intensity greatly reduces.Simultaneously because the engineering time shortens, the staff reduces, without main equipment, so inspection and repair shop costs also and significantly reduces.
