Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drain pot and a drain trap device used when draining drainage from pressurized air used in factories and the like.

[0002]

2. Description of the Related Art In various factories, a large amount of compressed air is used for motive power, instruments, etc. However, the inclusion of drains shortens the life of pipes and ensures proper operation of instruments. It will interfere with the operation, so I always try to pull out the drain.

Conventionally, drainage is carried out by providing a drain trap in the drainage pipe branching from the pressure air pipe.
Since it contains iron rust and other foreign matter mixed in from the air compressor, piping, etc., the foreign matter is likely to clog the drain trap. Therefore, it is necessary to disassemble and clean the drain trap regularly, but such disassembly and cleaning work are troublesome, and the large factory has hundreds to thousands of installations, which results in high maintenance costs. Therefore, improvement is desired.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned requirements, and an object thereof is to easily remove iron rust and other foreign matter contained in the drain. Whether the drain pot and maintenance such as disassembly and cleaning are not required, or the period can be greatly extended, not only can the operator be freed from the trouble of maintenance, but also the maintenance cost can be greatly reduced. It is to provide a drain trap device capable of

[0005]

In order to achieve the above object, the present invention provides a casing, a strainer for dividing the inside of the casing into a front chamber and a rear chamber, and a drain inlet provided in the upper portion of the front chamber. And a drain discharge port provided in the lower portion of the front chamber and a drain discharge port provided in the rear chamber.

Further, according to the present invention, in the drain pipe, a casing, a strainer for dividing the inside of the casing into a front chamber and a rear chamber, a drain inlet provided in an upper portion of the front chamber, and a lower portion of the front chamber. A drain trap having a foreign matter discharge port provided in the drainage chamber and a drain discharge port provided in the rear chamber at its drain inlet port, and a drain trap connected to the drain discharge port. I will provide a.

The drain pot of the present invention will be described in detail based on one embodiment thereof. In FIG. 1, the drain pot has a casing 1. A strainer 2 extending in the vertical direction is provided in the casing 1, and the strainer 2 divides the interior of the casing 1 into a front chamber 3 and a rear chamber 4. The strainer 2 has a lower part configured as a perforated plate having a large number of drain passage holes 5 having a diameter of several millimeters, and an upper part connecting the front chamber 3 and the rear chamber 4 and also having a diameter of several millimeters. Or several pressure equalizing holes 6 are provided.

At the upper part of the front chamber 3, a drain inlet 7 connected to a drain pipe branching from the pressure air pipe is provided, and at the lower part, a foreign matter discharge port 9 having a valve 8 is provided. . A pressure equalizing port 10 connected to a drain trap, which will be described later, is provided in the upper portion of the rear chamber 4, and a drain discharge port 11 is provided below the pressure equalizing port 10.

Now, it flows in from the drain inlet 7.
Drain containing iron rust and other foreign matter is guided to the front chamber 3, but does not flow into the rear chamber 4 at a stretch because of the strainer 2, and a slow flow is formed through the drain passage hole 5 to prevent foreign matter. Precipitation occurs in the front chamber 3 before the strainer 2. The settled foreign matter is appropriately discharged from the foreign matter discharge port 9 to the outside of the drain pot by opening the valve 8. On the other hand, the drain is guided to the rear chamber 4 through the drain passage hole 5 of the strainer 2 and is discharged from the drain discharge port 11 as so-called clean drain.

The drain pot shown in FIG. 1 can be used to construct the drain trap device shown in FIG.
That is, a well-known drain trap 14 of, for example, a bucket type or a float type is connected to the drain drain pipe 13 having a valve 17 and branched from the pressure air pipe 12. Then, on the upstream side of the drain trap 14, the drain pot 15 shown in FIG. 1 is connected to the drain discharge pipe 13 at the drain inlet 7 (FIG. 1), and the drain outlet 11 (FIG. 1) is connected to the pipe 18. Through the drain trap 14
Connect to. At this time, it is preferable to connect the drain trap 14 and the pressure equalizing port 10 (FIG. 1) of the drain pot 15 with a pressure equalizing pipe 16. With this configuration, the drain pot 15
Since the so-called clean drain after the iron rust and other foreign substances have been removed is guided to the drain trap 14, clogging can be prevented.

[0011]

The drain pot of the present invention comprises a strainer that divides the interior of the casing into a front chamber and a rear chamber, a drain inlet provided in the upper portion of the front chamber, and a foreign matter discharge outlet provided in the lower portion of the front chamber. And the drain outlet provided in the rear chamber, it is possible to easily remove iron rust and other foreign matter contained in the drain in the front chamber. Further, the drain trap device of the present invention, while connecting the drain trap to the drain pipe, is connected to the drain pot described above on the upstream side, the drain after removing iron rust, other foreign matter in the drain pot. Is guided to the drain trap, it becomes possible to prevent clogging of the drain trap, and maintenance such as disassembling and cleaning is not necessary, or the cycle can be greatly extended, and maintenance is troublesome. Not only can people be released, but maintenance costs can be greatly reduced.
