One end of the first pipes 32a, 32b, 32c, and 32d is connected to the air compressors 10a, 10b, 10c, and 10d, and the other end penetrates the bottom surface 3 of the engine compartment 2 and is below the bottom surface. Extends. The other end of the first pipes 32a, 32b, 32c, and 32d is connected to the second pipe 34.

Accordingly, the drain introduced into the first pipes 32a, 32b, 32c, and 32d is formed to flow into the second pipe 34 through the first pipes 32a, 32b, 32c, and 32d. Although not shown, valves are installed in the first pipes 32a, 32b, 32c, and 32d to open and close the first pipes 32a, 32b, 32c, and 32d.

At this time, according to one embodiment of the present invention, the diameter of the second pipe 34 is formed larger than the diameter of the first pipe (32a, 32b, 32c, 32d). For example, the diameter of the first pipe (32a, 32b, 32c, 32d) is 25A (34mm), the diameter of the second pipe 34 may be 80A (89.1mm), but the first pipe and the second pipe The diameter of is not limited thereto.

The third drain line part 50 is installed. The third drain line part 50 discharges the drain generated while the air from the air compressors 10a, 10b, 10c, and 10d passes through the separators 70a, 70b, 70c, and 70d to the drain tank 80. It is for the configuration.

According to one embodiment of the invention, the transfer lines 12a, 12b have separators 70a, 70b, 70c, 70d to remove the drain contained in the air generated from the air compressors 10a, 10b, 10c, 10d. The oil and water are separated from the separators 70a, 70b, 70c, and 70d, and only pure air is transferred to the air storage tanks 20a and 20b.

At this time, drains of oil and water generated in the separators 70a, 70b, 70c, and 70d are transferred to the second pipe 34 through the third drain line part 50 and then discharged to the drain tank 80. do.

Referring to FIG. 2, the third drain line part 50 includes a fifth pipe 120, a through pipe 100, and a sixth pipe 130.

The tubular body 110 is a tubular member installed through the opening 4 formed in the bottom surface 3 of the engine compartment 2 in which the air compressors 10a, 10b, 10c, and 10d are installed.

Body support plate 112 is one side is connected to the outer peripheral portion of the tubular body 110, the other side is coupled to the upper side of the bottom surface 3, the tubular body 110 is to be fixed position relative to the bottom surface (3) To help. The body support plate 112 may be formed in a disc shape.

Upper and lower flanges 114 and 116 are formed at upper and lower ends of the tubular body 110, respectively, so that the fifth pipe and the sixth pipe may be connected to the upper and lower parts of the tubular body 110.

Holes 118 are formed in the upper and lower flanges 114 and 116 so that the tubular body 110 can be connected by other conduits and coupling members 140 such as bolts 142 and nuts 144.

The fifth pipe 120 is connected to the upper end of the tubular body 110. At this time, the fifth pipe is connected to the through pipe 100 by the connecting member 150.

The connection member 150 includes a flange portion 154 corresponding to the upper flange 114 of the through pipe 100 and a boss portion 152 formed on the flange portion 154.

 The lower end of the connecting member 150 is formed with a flange portion 154 to be connected to the upper flange (114).

In the flange portion 154, a hole 158 is formed at a position corresponding to the hole 118 of the upper flange 114 of the tubular body 110, such that the connecting member 150 is connected to the tubular body by the coupling member 140. It may be connected to 110.

Meanwhile, the fifth pipe 120 may be in the form of a tube formed of copper material.

In addition, valves 72a, 72b, 72c, and 72d may be installed in the fifth pipe 120 to open and close the fifth pipe 120.

In this case, the valves 72a, 72b, 72c, and 72d may be solenoid valves.

At this time, the solenoid valve may be formed so that the valve is automatically opened when the drain filtered by the separator (70a, 70b, 70c, 70d) exceeds a predetermined pressure to discharge the drain.

The sixth pipe 130 is connected to the lower end of the tubular body 110.

In addition, in the case of a drain line formed of a copper tube, the diameter is relatively small, and when the sludge precipitates inside the drain line as time elapses during the operation, the tube is clogged and the drain flows backward.

However, according to the exemplary embodiment of the present invention, the fifth pipe 120 connected to the transfer lines 12a and 12b is formed of a copper material line, but the length of the fifth pipe 120 is reduced, and the bottom surface 3 ) And separately install the through pipe 100 having a larger diameter than the fifth pipe 120 and then connect the upper end of the through pipe 100 and the fifth pipe 120 using the connecting member 150 to drain the line. It is easy to install.

In addition, when the diameter of the through pipe 100 and the diameter of the sixth pipe 130 connected to the downstream of the through pipe are formed to be larger than the fifth pipe 120 made of copper material, the drainage flow may cause a backflow of the drain due to the blockage. Can be minimized.

When the sixth pipe 130 connecting the second pipe 34 to the second pipe 34 from the lower end of the through pipe 100 is formed of a steel material, the diameter of the pipe is improved while the strength of the pipe is increased. It can widen and workability becomes good.

In addition, in the case of connecting the pipes from the transfer lines 12a and 12b to the second pipe 34 by one copper tube, the replacement and repair of the line is not easy, but as in the present embodiment, the fifth pipe ( 120), when the drain drain line is formed by the through pipe 100 and the sixth pipe 130, the pipe replacement and repair work may be easily performed.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
