Description

[0001] PIPE CLEANING APPARATUS [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a pipeline cleaning apparatus, and more particularly, to a pipeline cleaning apparatus that removes foreign matter from various pipes to smooth fluid flow.

In general, there are equipment using piping, ultrasonic waves, ozone and the like as piping cleaning equipments. Among them, cleaning to remove scale inside piping is mainly used by poly-pigs moving by hydraulic pressure.

However, there is a problem in that the cleaning efficiency is low even though the equipment is expensive.

In addition, a cleaning device using a water jet in Patent Registration No. 796820, a cleaning device using steam injection in Patent Publication No. 2009-25556, a cleaning device using cleaning water microparticles obtained by mixing washing water and compressed air in Patent Registration No. 855309 .

It is true that these devices also suffer from poor cleaning efficiency, although they are expensive. This problem is caused by the fact that there is a considerable lack of physical force required to remove the scale of the inner wall of the pipe, that is, a constant frictional force required for proper position. On the other hand, there is also a problem that it is not suitable for cleaning piping of a narrow diameter.

On the other hand, Korean Patent Registration No. 751385 discloses a pipe cleaning screw.

In the prior art, a brush having a large physical effect is attached to a screw, and compressed air is introduced into a pipe to apply a rotational force to the screw, thereby effectively removing the inner wall scale by the rotating brush.

The prior art has advantages over the above devices in that it directly rubs against the inner wall scale using a brush as a cleaning material.

However, when the compressed air is supplied to the pipe for rotating the screw, energy loss is large, and no desired torque or thrust is generated.

It is possible to compensate a little by connecting several screws in series, but in this case, it is inconvenient to assemble and disassemble and there is a problem that it is separated from the middle of the pipe during the work.

Japanese Laid-Open Patent Publication No. 2002-102812 (Apr. 9, 2002), Japanese Laid-Open Patent Publication No. 2006-088002 (2006.04.06.), Japanese Laid-Open Patent Publication No. 2010-253425 (Laid on Nov. 11, 2010) There is a problem that the cleaning force is slightly lowered due to the simple injection propulsion method of the nozzle and the cleaning is performed at a high pressure of 350 bar or more for the rotation of the nozzle and the moving direction of the nozzle for more uniform cleaning There is a risk of wasting energy and cost, as well as damaging the object to be cleaned.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the problems of the prior art described above, and it is an object of the present invention to provide a method and an apparatus for circulating a fluid in a high pressure hose, The sludge and scale of the inside of the pipe can be properly titled and can be directly removed with a certain physical force by discharging the foreign substance out of the process of propelling the rotatable nozzle and eliminating the scales fixed by the proper brush attached to the outer surface of the rotator, And an object of the present invention is to provide a pipeline cleaning apparatus which is capable of cleaning a pipeline.

An object of the present invention is to provide a high-pressure hose for supplying high-pressure compressed air or a liquid-like fluid; A concentric shaft having both ends opened, a passage formed inside, a discharge hole formed in the outer surface, a spiral formed in the rear passage, a tapered outer surface formed at one end, and a one end connected to the high pressure hose; A screw bushing coupled to an outer circumferential surface of the concentric shaft and having a spiral flow path formed on an outer circumferential surface thereof; A rotor enclosure having both ends thereof opened, a passageway formed therein, a step formed at the center of the inner periphery thereof to form a receiving space on both sides thereof, and coupled to the outside of the screw bushing and the concentric shaft; And a tip having a threaded portion formed on one side thereof and a head formed on the other side thereof and having a nozzle hole communicating with the threaded portion and the head.

And a bearing coupled to the inside of the screw bushing and coupled to the outer surface of the concentric shaft.

The screw bushing is characterized in that a thread is formed on the outer circumferential surface to form a spiral flow path to form a rotation and a thrust.

And a discharge hole is formed on the inner surface of the rotor enclosure so that the spiral flow path of the screw bushing passes.

And a rear end screw bushing fitted to the rear of the outer circumferential surface of the concentric shaft and having a spiral flow path formed on the outer circumferential surface thereof.

According to the present invention, since the fluid introduced into the high-pressure hose is discharged to a plurality of screws before and after the rotary nozzle, the object can be efficiently washed with the high efficiency energy and the constant rotation and spraying power.

In addition, it is possible to remove the scale fixed by the cleaning means attached to the outer surface of the rotating body, and the sludge and scale inside the tube can be removed efficiently and with appropriate physical force by discharging the foreign substances out of the process of propelling the rotating type nozzle .
