Abstract

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a pipe cleaning apparatus for cleaning foreign matter and oil on a surface of a pipe, and more particularly to a pipe cleaning apparatus for vertically rotating both ends of a cleaning chamber accommodating a plurality of pipes, And the cleaning liquid charged in the cleaning chamber moves left and right to remove foreign matter and oil on the inner and outer surfaces of the pipe.

Description

{Apparatus for Cleaning Pipes}

Generally, the tubular pipe is formed by sequentially releasing a steel plate strip (STRIP) wound in a coil shape and supplying it to a tube forming apparatus, shaping the metal pipe into a metal pipe while passing through a molding apparatus, The metal pipe is cut by a cutter to a predetermined length and is passed through a polishing machine to polish the outer circumferential surface. As for a conventional metal pipe manufacturing system, Korean Utility Model Registration No. 187051 entitled " Pipe making device "is known. A pipe having a small diameter may be manufactured by forming a metal plate round and joining the ends, or by drawing through a die.

Foreign matter and oil are deposited on the inner and outer surfaces of the pipe manufactured through the pipe making process and the drawing process. Particularly, since a large amount of drawing oil is used for drawing, drawing oil is applied to the inner surface of the pipe. Therefore, a cleaning process is required to remove foreign matter and oil from the surface of the pipe during the manufacturing process of the pipe.

For example, FIG. 5 shows a cleaning apparatus according to this prior art. As shown in the figure, the cleaning vessel 21 is filled with a predetermined amount of the cleaning liquid 23, and the vibrator 22 is disposed at one portion of the bottom of the cleaning vessel 21. The cleaning liquid 23 is vibrated at a predetermined frequency by the vibrator 22. The cleaning liquid 23 filled in the cleaning container 21 is circulated by the pump 26 through the outflow pipe 25 and the inflow pipe 27. The outflow pipe 25 and the inflow pipe 27 are fixed to a part of the cleaning container 21 and allow the cleaning liquid 23 contained in the cleaning container 21 to flow along the closed circulation flow path. A vortex pipe (31) is installed in the cleaning container (21). The vortex pipe (31) is provided with an outlet (32) through which vortex flows. The kinetic energy generated by the vortex formed in the vortex pipe 31 is transmitted to the cleaning liquid 23 together with the vibration energy generated from the ultrasonic vibrator 22, Action can be performed.

However, the cleaning container 21 according to the related art has a rectangular shape and can not accommodate a long pipe. Since the upper portion of the cleaning container 21 is opened, it is very difficult to insert or discharge the pipe. For example, since a plurality of pipes are rope-bundled and a crane or a lift is used to feed or discharge the pipe to the opening of the cleaning container 21, the operation is inconvenient and takes a long time.

Further, since the conventional cleaning container 21 is fixed on the paper surface, it does not flow into the cleaning liquid in the cleaning container 21, and thus the cleaning efficiency is lowered. In order to solve this problem, there has been a limit in generating vibration or vortex using the vibrator 22 or the outflow pipe 25 but removing the oil contained in the pipe. In addition, the conventional cleaning container 21 is open at its upper portion, and there is a problem that the odor generated in the cleaning liquid leaks to contaminate air circulation around the cleaning container 21.

When the rod of the hydraulic cylinder 82 is extended, the hook 83 is pivoted downward to engage with the engaging step 45. When the rod of the hydraulic cylinder 82 is contracted, And is separated from the engagement protrusion 45. [ Thus, the pallet 40 and the pallet transporting loader 60 can be connected or disconnected by rotating the hook 83 up and down.

Hereinafter, a method of using the automatic pipe cleaning apparatus 1 according to the present invention will be described.

First, a plurality of pipes (2) having foreign matter and oil on the inner and outer surfaces thereof are put on the pallet (40) while passing through the pipe making process or the drawing process. For example, 20 to 50 pipes may be placed on the pallet 40 according to the diameter. At this time, the pallet 40 is placed on the pallet transporting device 70.

When the pipe 2 is loaded on the pallet 40, the pallet transport loader 60 and the pallet 40 are connected. The pallet transporting loader 60 is moved toward the cylindrical chamber 11 in a state where the door 12 of the cylindrical chamber 11 is opened and the pallet 40 is inserted into the cylindrical chamber 11. Then, the door 12 is closed to seal the inner space of the cylindrical chamber 11 completely.

Then, a cleaning liquid is injected through the cleaning liquid injection port 15 to fill the inside of the cylindrical chamber 11 with a cleaning liquid. Chamber actuators 30a and 30b provided at both ends of the cylindrical chamber 11 are sequentially operated so that the cylindrical chamber 11 is installed at the lower center of the cylindrical chamber 11 when the cleaning liquid is filled in the cylindrical chamber 11 at an appropriate height So as to vertically rotate about the chamber supporting portion 20.

For example, as shown in FIG. 8 (a), when the first chamber driving part 30a is raised and lowered and the second chamber driving part 30b is moved down, the cylindrical chamber 11 is supported by the chamber supporting part 20, The left side is raised to the upper side and the right side is lowered. Then, the cleaning liquid in the cylindrical chamber 11 flows to the right and cleans the inner and outer surfaces of the pipe 2. 8 (b), when the second chamber driving part 30b is moved up and down and the first chamber driving orifice 30a is moved up and down, the cylindrical chamber 11 moves to the chamber supporting part 20 The center is raised to the right and the left is lowered. Then, the cleaning liquid in the cylindrical chamber 11 flows to the left to clean the inner and outer surfaces of the pipe 2.

When the cylindrical chamber 11 is rotated up and down as described above, the cleaning liquid in the cylindrical chamber 11 flows left and right while flowing along the inner surface of the pipe 2, The oil is removed. At this time, when a medium made of metal or ceramics is inserted into the cleaning liquid in the cylindrical chamber 11, the medium rubs against the surface of the pipe 2 while moving together with the cleaning liquid, thereby improving the cleaning efficiency.

At this time, when the cylindrical chamber 11 rotates up and down, the fixing roller 33 provided on the driving table 31 serves to support the cylindrical chamber 11, and the compression spring 35, And serves to buffer shock applied to the cylindrical chamber 11 so that seam movement of the cylindrical chamber 11 can be smoothly performed.

In addition, the odor generated in the cleaning liquid in the cylindrical chamber 11 can be discharged to the outside through the odor discharge port 17, and then purified by the unpleasant odor removal facility to prevent the surrounding air from being contaminated.

When the cleaning operation is completed for a predetermined time, the operation of the chamber driving units 30a and 30b is stopped and the cleaning liquid is discharged to the outside through the cleaning liquid discharge port 16. [ Thereafter, the pallet 40 is connected to the pallet transporting loader 60 while the door 12 is opened. Thereafter, the pallet transporting loader 60 is moved to discharge the pallet 40 from the cylindrical chamber 11 Thereby completing the pipe cleaning process according to the present invention.

An embodiment of the present invention described above and shown in the drawings should not be construed as limiting the technical idea of the present invention. The scope of protection of the present invention is limited only by the matters described in the claims, and those skilled in the art will be able to modify the technical idea of the present invention in various forms.
