Description

The present invention relates to a collection device that is attached to a drainage route and collects foreign matter in the drainage route and foreign matter from wastewater flowing into the drainage route.

As a conventional technique, there is an aircraft drainage system described in Patent Document 1. The waste water from aircraft hand wash basins is collected in a water storage tank and drained into the toilet bowl by a pump.When the water level in the water storage tank becomes high enough to flow back into the washbasin, a valve is used to drain the overflow. It is. When this drainage system is used, the waste water used in the hand wash basin is temporarily stored in the water storage tank, making it possible to use the waste water in the water storage tank for secondary use when flushing the toilet bowl.

Further, as a conventional technology of a structure for collecting foreign matter in waste water from an aircraft hand wash basin, there is one described in Patent Document 2. According to this conventional technology, in hand washing in an aircraft toilet, a filter is provided in the drain port of the hand washing device and in a water storage tank that stores waste water from the hand washing device. According to this configuration, it is possible to collect foreign substances in the waste water generated in the hand wash basin by the inlet of the drainage path (the drain outlet of the hand wash basin) and the filter in the water storage tank.

Special table number 2015-522729

German Published Patent Publication No. 10229799

In the drainage system disclosed in Patent Document 1, the waste water generated in the hand wash basin is stored in a water storage tank and then used for secondary use in flushing the toilet bowl. However, this conventional example does not have a foreign matter collection device, so waste water generated from the hand wash basin is used for secondary use for flushing the toilet bowl. Foreign matter such as dirt and hair was mixed into the wastewater and it was used as toilet flushing water. For this reason, if a foreign object is mixed in the flush water, the user of the toilet can see the foreign object, which increases the discomfort of the user of the toilet. In addition, if a user accidentally drops a ring or other object into the inlet of a hand wash basin, the water will be drained directly into the toilet tank via the water storage tank and toilet bowl, so it is necessary to first drop the foreign object such as a ring into the inlet. It was difficult to get it back.

In the drainage system disclosed in Patent Document 2, wastewater generated in an aircraft hand wash basin is stored in a water storage tank and then used for secondary use in flushing the toilet bowl, but in this conventional example, a filter is configured in the drainage path. Naturally, it is necessary to periodically clean the foreign matter collected by the filter. However, the technique disclosed in Patent Document 2 does not take into account maintenance of the filter.

The present invention was invented in view of the above-mentioned problem, and is capable of trapping foreign matter in a drainage path, making regular maintenance of the drainage path easy by making it possible to easily attach and detach the collection unit from the drainage path. Provide a collection device.

The drainage path collection device of the present invention includes an insertion member 3 equipped with a first collection portion 4 that can be detachably attached to an opening 23 that opens laterally with respect to the pipe axis direction of the drainage path 1. This is a foreign matter collection device for a drainage path, characterized in that an opening and a closing portion 31 are connected in a watertight manner, and further comprising: By rotating and attaching it to the opening, it forms an inclined surface for closing the opening and guiding the insertion member 3 to a proper position, and matches the inclined surface 36 with the drainage path 1 into which the insertion member 3 is inserted. It constitutes the inclined surface 27.
Further, the drainage route 1 may be a route connecting a hand washing basin 5 and a toilet bowl 52 of a vehicle, for example, or the collection rates of the second collection section 6 and the first collection section 4 provided at the inlet 11 may be made different. It is something to do.

According to the present invention as set forth in claim 1, the insertion member 3 includes the first collecting portion 4 that can be detachably attached to the opening 23 that opens laterally with respect to the pipe axis direction of the drainage path 1. Since the opening 23 of the drainage route 1 and the closing part 31 of the insertion member 3 are connected in a watertight manner, even when a large amount of drainage flows in for a short period of time, the drainage route 1 There is no possibility of water leaking between the and the insertion member 3. In addition, since the insertion member 3 is detachable from the side of the drainage path 1, it is possible to remove the insertion member 3 in a narrow space, and the first collection part 4 provided in the insertion member 3 can be cleaned easily. This makes it possible to maintain the first collection section 4 easily.
According to the second aspect of the invention, the closing part 31 is rotatably attached to the first collection part 4, and the opening 23 is closed by rotating and attaching the closing part 31 to the opening 23. By doing so, it becomes possible to remove the insertion member 3 within a narrow space. Further, even if negative pressure or overpressure is applied in the drainage path 1, pressure is applied to the blockage part 31 from the upstream or downstream side, but the blockage part 31 is firmly connected to the opening part 23. Therefore, it will not come off due to fluctuations in air pressure in the drainage path 1.
According to the present invention as set forth in claims 3 and 4, the insertion member 3 is provided with the inclined surface 36 for guiding the insertion member 3 to an appropriate position in the drainage path 1, and the inclined surface is formed in the drainage path 1. 36, the inclined surface 36 of the insertion member 3 comes into close contact with the inclined surface 27 of the drainage path 1, and the horizontal stress is further reduced to the vertical stress. is converted to This allows the packing 39 attached to the inclined surface 36 to be pressed against the inclined surface 27.
According to the present invention as set forth in claims 5 and 6, the path connecting the handwash basin 5 and the toilet bowl 52 is the drainage path 1, and the drainage path 1 is provided with at least one first collection section 4. When the waste water from the handwash basin 5 is used for secondary purposes for cleaning the toilet bowl 52, it becomes possible to collect foreign substances in the waste water, and there is no possibility that foreign substances will be mixed into the waste water when cleaning the toilet bowl 52. .
According to the present invention as set forth in claim 7, the inlet 11 through which wastewater flows into the drainage path 1 is configured with a collection rate different from the collection rate of the first collection part 4, and the inlet 11 has a collection rate different from that of the first collection part 4. Since the second collection part 6 is provided to collect foreign matter in the inflowing wastewater, the second collection part 6 attached to the inlet 11 must be frequently cleaned and maintained. The foreign matter that could not be collected by the second collecting part 6 of the drainage path 1 is collected by the first collecting part 4, which can collect a larger volume than the second collecting part 6, and the first collecting part 4 is replaced by the second collecting part 6. It is possible to perform maintenance without maintenance for a longer period than the maintenance period of the collecting section 6.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A foreign matter collection device for a drainage path according to the present invention will be described below with reference to the drawings. It should be noted that the following description is intended to facilitate understanding of the embodiments, and is not to be understood as limiting the present invention.
Note that the joint member 2 in this embodiment is attached to a drainage path 1 that connects a wash basin 5 and a toilet bowl 52 of a vehicle, as shown in FIG. Note that a vehicle refers to a passenger transportation facility such as an aircraft, a vehicle, a railway, or a ship.
The hand wash basin 5 is a tank body used by a user to wash their hands, and has an inlet 11 at the bottom for discharging wastewater generated on the hand wash basin 5 downstream.
A second collection section 6 is detachably disposed in the inlet 11 and collects foreign matter such as dust and hair mixed in the wastewater flowing into the inlet 11.
The drainage route 1 is composed of pipes 100, 200, and 300, a joint member 2, and a water storage tank 51.
The pipe 100 is a pipe body through which waste water passes, and its upper end is connected to the inlet 11 of the washbasin 5, and its lower end is connected to the upper end of the joint member 2.
The pipe 200 is a pipe body through which waste water passes, and its upper end is connected to the lower end of the joint member 2, and its lower end is connected to the water storage tank 51.
The pipe 300 is a pipe body through which waste water passes, and its upper end is connected to the water storage tank 51, and its lower end is connected to the toilet bowl 52.
The joint member 2 is connected to a pipe 100 on the upstream side of the joint member 2, and a pipe 200 on the downstream side of the joint member 2.
The water storage tank 51 is a tank that temporarily stores the waste water generated from the hand wash basin 5, and the waste water in the water storage tank 51 is used as flush water for the toilet bowl 52 installed downstream. A pipe 200 is connected to the upstream side of the water storage tank 51, and a pipe 300 is connected to the downstream side of the water storage tank 51.
The toilet bowl 52 is a device used for excreting urine and urine, and the waste water from the water storage tank 51 is used as flushing water for the toilet bowl 52. A pipe 300 is connected to the upstream side of the toilet bowl 52, and a sewer pipe is connected to the downstream side of the toilet bowl 52. Note that the sewage pipe downstream of the toilet bowl 52 employs a vacuum toilet piping system that is common as an aircraft toilet drainage system.

As shown in FIGS. 2 and 3, the joint member 2 as the drainage path 1 in the present invention has an upstream opening 21 formed at the upstream end and a downstream opening 22 formed at the downstream end. , has an opening 23 formed laterally with respect to the pipe axis direction of the joint member 2 which is a part of the drainage path 1, and has a first trap described later between the upstream opening 21 and the downstream opening 22. A storage chamber 25 in which the collecting section 4 is arranged is formed. Note that lateral to the pipe axis direction of the drainage route 1 refers to a direction that intersects substantially perpendicularly to the pipe axis direction of the drainage route 1 . Further, the insertion member 3 inserted through the opening 23 is arranged in the storage chamber 25.
The upstream opening 21 is an opening formed at the upper end of the joint member 2, and is connected to a pipe 100 that is a part of the upstream drainage path 1. Further, the downstream opening 22 is an opening formed at the lower end of the joint member 2, and is connected to a pipe 200 that is a part of the downstream drainage path 1.
The opening 23 is an opening formed on the side surface of the joint member 2, and a protrusion 24 that slides within the groove 311 of the insertion member 3 is formed on the inner periphery.
The storage chamber 25 has a storage space in which the insertion member 3 can be placed, and a mounting groove 26 is formed at its upper end and at a position continuous with the lower end of the upstream opening 21. As shown in FIG. 3, the mounting groove 26 is formed so as to bulge outward in the width direction of the joint member 2, and has an inclined surface 27 and a guided portion 28. The inclined surface 27 is the upper surface of the mounting groove 26, is formed at the lower end of the upstream opening 21, and is inclined toward the upstream opening 21 as it goes toward the opening 23. Therefore, the inclined surface 27 is inclined with respect to the axial direction of the opening 23 and the insertion direction of the insertion member 3, which will be described later. Further, the inclined surface 27 comes into contact with the inclined surface 36 of the insertion member 3. The guided portion 28 is the lower surface of the attachment groove 26 facing the inclined surface 27, and when the insertion member 3 is inserted, the first collection portion 4 is guided by coming into contact with the guide portion 37 of the insertion member 3. This prevents it from being separated from the inclined surface 27. In this embodiment, the inclined surface 27 is formed parallel to the insertion direction of the insertion member 3, but may be inclined toward the downstream opening 22 as it goes toward the opening 23.

As shown in FIGS. 3, 4, and 6, the insertion member 3 has a closing part 31, a fixing part 34, and a first collecting part 4.
The closing part 31 has a circular shape whose outer diameter is approximately the same as that of the opening 23, and a groove 311 in which the protrusion 24 slides is threaded on its outer periphery. Furthermore, a handle 32 is formed on the side surface of the closing portion 31 that is exposed from the joint member 2 upon completion of construction, and the closing portion 31 and the fixed portion 34 can be relatively rotated on the side opposite to the handle 32. A circular fitting portion 33 is formed to be connected as shown in FIG.
The fixing part 34 has a claw part 35 that fits into the fitting part 33, an inclined surface 36 and a guide part 37 arranged in the storage chamber 25, and has a position that is continuous with the lower end of the upstream opening 21 when construction is completed. The first collection section 4 is attached to the opening 341 formed in the opening 341 . Further, the fixing part 34 has an annular packing 38 on the outer periphery of the claw part 35 at a position that abuts the inner periphery of the opening 23, and a packing 39 on the inclined surface 36 at a position that abuts the inclined surface 27. have. The inclined surface 36 is formed on the upper surface of the fixing part 34 and is inclined at the same angle as the inclined surface 27 of the storage chamber 25. It comes into close contact with the inclined surface 27. The guide portion 37 is formed on the lower surface of the fixing portion 34 and comes into contact with the guided portion 28 when the insertion member 3 is placed within the joint member 2 . The opening 341 is formed so as to vertically penetrate the fixing portion 3 at a position directly below the upstream opening 21 . A protruding connecting portion 342 is formed on the inner periphery of the opening 341, and the first collecting portion 4 is attached to the connecting portion 342 and a connected portion 41, which will be described later. The diameter of the opening 341 is reduced on the upstream side, and the packing 40 comes into contact with the inner circumferential surface of the reduced diameter portion when the first collection section 4 is attached. Thereby, the opening 341 is watertightly closed. Further, the opening 341 is formed with a flange 343 that projects outward at the lower end.
The first collection section 4 is a collection device detachably attached to the opening 341 of the fixing section 34, and includes a plurality of openings or a net-like body at the bottom thereof. By having a plurality of openings in the first collecting part 4 or by using a net-like body, it becomes possible to collect foreign substances in the waste water passing through the drainage path 1. Note that the collection rate of the first collection section 4 and the collection rate of the second collection section 6 described above are different. Specifically, the collection rate of the second collection section 6 is configured to be higher than that of the first collection section 4. This is a case where the area of one of the plurality of openings in the second collecting section 6 is larger than the area of one of the plurality of openings in the first collecting section 4. Incidentally, the collection rate in the present invention refers to the collection rate of foreign matter in the waste water during drainage through the drainage route 1.
Further, as shown in FIG. 6(b), the first collecting part 4 has a packing 40 attached near the upper end that contacts the inner periphery of the fixing part 34, and the connecting part 342 is attached to the outer periphery of the packing 40. A groove-shaped connected portion 41 that engages is formed.
Furthermore, the first collection part 4 is equipped with a water passage opening made of a mesh-like metal material, and this opening makes it possible to collect foreign matter in the drainage path 1. The opening area of the first collecting section 4 is smaller than the opening area of the second collecting section 6 of the inlet 11. This allows the first collection section 4 to collect foreign matter in the drainage path 1 that could not be collected by the second collection section 6.

The attachment of the pipe 100 and pipe 200 to the joint member 2 will be explained.
First, the pipe 100 is connected to the hand washing basin 5, and the joint member 2 is attached between the pipe 100 and the pipe 200 by adhesive. At this time, the pipe 100 and the pipe 200 communicate with the drainage path 1 via the joint member 2. Further, a water storage tank 51 is connected to the pipe 200, and a pipe 300 is connected downstream of the water storage tank 51. Then, the toilet bowl 52 is connected to the lower end of the pipe 300.
Next, the first collecting part 4 is inserted into the opening 341 of the fixed part 34, and the first collecting part 4 is rotated while the connecting part 342 is pressed against the connected part 41. At this time, the packing 40 comes into contact with the inner circumferential surface of the opening 341, and the opening 341 is watertightly closed, and the protruding connecting portion 342 is disposed within the groove-shaped connected portion 41, so that the fixed portion The first collection part 4 is attached and fixed to 34.
Next, the insertion member 3 is inserted through the opening 23. As shown in FIG. 3, the insertion is performed in a direction substantially horizontal to the guide part 37 and parallel to the axial direction of the guided part 28. Then, after the protrusion 24 of the opening 23 comes into contact with the groove 311 of the closing part 31, the insertion member 3 is placed in the storage chamber 25 by rotating the closing part 31. Note that since the groove portion 311 is formed in a spiral shape, the protrusion 24 slides within the groove portion 311 as the closing portion 31 rotates, and due to the sliding, the rotational movement of the closing portion 31 causes the insertion member 3 to be accommodated. This is converted into a horizontal stress that moves toward the chamber 25 side. As a result, the insertion member 3 moves further to the back of the storage chamber 25. Further, the guide portion 37 of the insertion member 3 comes into contact with the guided portion 28 and moves along the guided portion 28 to the back side of the storage chamber 25, and the inclined surface 27 of the joint member 2 and the insertion member 3 The inclined surface 36 of is pressed into contact with the gasket 39 via the packing 39. At this time, the insertion member 3 approaches the inclined surface 27 and the inclined surface 36 and comes into pressure contact with each other, so that the stress in the horizontal direction is further converted into stress in the vertical direction. As a result, the packing 39 is pressed against the inclined surface 27 and the upstream opening 21 is closed. Note that the converted vertical stress also acts to push down the inclined surface 36 of the insertion member 3, but the guide portion 37 of the insertion member 3 is supported by the guided portion 28 of the joint member 2. Therefore, the inclined surface 27 and the inclined surface 36 are prevented from being separated from each other.
When the insertion member 3 is placed in the storage chamber 25, the packing 39 comes into contact with the inclined surface 27, and the drainage path is closed by the first collection part 4. Further, the opening 23 and the closing portion 31 can be made watertight by the packing 38 attached to the fixed portion 34, thereby preventing fluid such as water inside from leaking to the outside from the opening 23. This makes it possible for the first collection section 4 to collect foreign matter in the drainage water in the drainage path 1 .
Further, even when negative pressure or overpressure is applied in the drainage route 1, pressure is applied to the blockage 31 from the upstream or downstream side, but the blockage 31 comes off due to fluctuations in air pressure in the drainage route 1. There is no need to worry.

When performing maintenance inside the drainage path 1, rotate the blocking part 31 in the opposite direction to the direction in which the insertion member 3 was placed, remove the insertion member 3 from the joint member 2, and remove the insertion member 3 from the side of the drainage path 1. The first collection section 4 attached to the removed and inserted member 3 is maintained. In addition, since the insertion member 3 is made detachable from the side of the drainage path 1, it is possible to take out foreign matter accumulated in the first collection part 4 provided in the insertion member 3, or to remove the inside of the first collection part 4. It becomes possible to clean it, and maintenance becomes easy. In addition, since the collection rate of the first collection section 4 is higher than that of the second collection section 6, the locations where foreign objects can be collected are divided according to the size of the foreign objects in the drainage route. This makes it possible to set the timing of cleaning over a long period of time, especially when used for the drainage route 1 of an aircraft or vehicle. In addition, the second collection section 6 attached to the inlet 11 is frequently cleaned and maintained, and foreign matter that cannot be collected by the second collection section 6 is removed from the second collection section 6 of the drainage route 1. Also, the first collection section 4 having a large capacity can be used to collect the water, so that the first collection section 4 can be maintained without maintenance for a longer period than the maintenance period of the second collection section 6.

In the foreign matter collection device for a drainage path according to the present invention, when installing the insertion member 3, the insertion member 3 can be installed by simply rotating the closing portion 31 after inserting it in the horizontal direction. Therefore, even if the joint member 2 (drainage path 1) is arranged in a narrow space, the insertion member 3 can be easily attached and detached.

The foreign matter collection device for the drainage route according to the first embodiment is as described above, but the shape of the foreign matter collection device for the drainage route of the present invention is not limited to the shape of the above embodiment, and within the scope of the gist of the invention.
