Description

[Detailed description of the invention] [Industrial application field] This invention is a chemical recovery device for trial and inspection of powder fire extinguishers, that is, useful for initial extinguishing in the event of a fire.
This invention relates to a chemical recovery device for trial use and inspection of a dry powder fire extinguisher that can emit powder chemical using an inert, nonflammable high-pressure gas such as nitrogen or carbon dioxide.

[Conventional technology]

In general, with this type of powder fire extinguisher, it is mandatory to periodically emit extinguishing agent from the fire extinguisher and check its performance and function in order to investigate whether there are any malfunctions due to changes over time. On the other hand, on the user's side, in order to be able to use the fire extinguisher quickly and accurately in the event of a fire, it is recommended that the user actually use the fire extinguisher and become familiar with its handling beforehand. It is desirable to keep 95 of the fire extinguishers currently installed in Japan.
Since more than % are this type of dry powder fire extinguisher,
It goes without saying that it is necessary to have experience in maintaining and using it.

[Problem that the invention attempts to solve]

However, the powder chemical filled in this dry powder fire extinguisher is made up of extremely fluid particles of 177 microns or less. Because the fire extinguisher is configured to emit nonflammable high-pressure gas to the outside, testing the radiation of the dry powder fire extinguisher itself as described above may cause the chemical powder to scatter, causing a nuisance to the surrounding area and causing various problems. There were concerns that this could not be carried out easily in residential areas where houses were densely packed.

[Means for solving problems]

This idea was developed in light of the conventional situation, and it is possible to do a radiation inspection trial of a dry powder fire extinguisher without scattering the emitted powder chemical to the surroundings.
Therefore, it is an object of the present invention to provide a chemical recovery device for trial use and inspection of powder fire extinguishers that can be easily carried out by anyone anywhere without taking up much space, and that is easy to carry and has a simple structure.

The chemical recovery device for trial and inspection of powder fire extinguishers of this invention consists of a bottomed cylindrical recovery device body that can be carried by hand, and a lid that can be tightly and removably fitted into the opening of the recovery device body. a deaeration device having a filter attached to an opening formed in a part of the lid body, a blowing device attached to an opening formed in a part of the lid body, and the blowing device , has a blowing pipe that fits into the nozzle of the fire extinguisher on the outside of the lid, and has a blowing pipe connected to the blowing pipe inside the lid in a communicating state, and has a lower open end closed and is connected to multiple locations around the surrounding area. It is characterized by comprising a blow-off pipe which is housed in the recovery device main body and which has an open blow-off port, and an extinguishing pipe which has an open lower end and surrounds the blow-off pipe at an appropriate interval. .

〔Example〕

Hereinafter, an embodiment of the chemical recovery device for trial use and inspection of a powder fire extinguisher according to this invention will be described in detail with reference to FIGS. 1a and 1b and FIG. 2.

FIGS. 1a and 1b are a plan view and a vertical cross-sectional view showing the general structure of the drug recovery device according to this embodiment, and FIG. 2 is a perspective view of the same in use.

That is, first of all, in FIGS. 1a and 1b, in this embodiment, there is a bottomed cylindrical collector body 1 that is container-shaped and can be carried by human hands, and a collector body 1 that can be tightly and removably fitted into the body 1. The lid body 2 is used. The combination of the recovery device main body 1 and the lid body 2 may be any combination having a sufficient internal container in the form of a so-called plastic bucket, such as a generally commercially available dust container, and both of these can be combined with a latch. It is desirable that the structure is such that it cannot be easily opened due to the

Therefore, a blowing device 4 having a deenergizing section 5 inside is provided in a part of the lid body 2 so as to communicate from the outside to the inside, and a degassing device having a filter inside is provided in another part. 6 is provided so as to communicate from the inside to the outside.

As the blowing device 4, an external bushing 7 is disposed from the outside in a partial opening of the lid body 2, an internal bushing 8 is screwed and fixed to the external bushing 7 from the inside via a holding cylinder 9, and then the external bushing 7 is screwed to the outside. The external bushing 7 forms a communication path to the inside.
A blowing pipe 12 is connected to the pipe via an intermediate connecting pipe 10 and a bent pipe 11 such as an elbow. This blowing pipe 12 is the nozzle 2 of the fire extinguisher 21.
2 are inserted and fitted together, and is made of, for example, a relatively flexible material and molded into a wrapper tube shape. Further, as the deenergizing part 5, a blow-off pipe 13 whose lower open end is closed with a cap 14 and blow-off ports 15 are opened at multiple locations around the inner bushing 8 is fitted, and a blow-off pipe 13 is fitted into the holding cylinder 9 to form a blow-off pipe 13, which has a lower open end closed with a cap 14 and has blow-off ports 15 opened at multiple locations around the inner bushing 8. It is constructed by fitting a de-energizing tube 16 that surrounds the tube 13 at appropriate intervals and has an open lower end. The inner bushing 18 is screwed and fixed to the outer bushing 17 in the same manner as described above to form a communicating path from the inside to the outside, and a filter 19 is provided inside the opening. .
In the figure, reference numeral 20 denotes an internal auxiliary container located inside the collector main body 1 and placed on the opening side of the blowout pipe 13 of the deenergizing section 5.

Therefore, in the case of this embodiment configuration, the powder fire extinguisher 21
To test and inspect the fire extinguisher, as shown in FIG.
2, insert the tip of the blow-out nozzle 22 into the blow-in tube 12 of the blow-in device 4, and if necessary, insert the blow-in tube 12 into the palm of one hand. Keep it inserted and squeeze it together, or just leave it inserted.
The fire extinguisher 21 may be activated by operating the trigger handle 23 of the fire extinguisher 21 with the other hand.

Through this operation, the extinguishing agent powder emitted from the fire extinguisher 21 by inert, nonflammable high-pressure gas such as nitrogen or carbon dioxide is transferred from the inside of the blowing pipe 12 to the blowing pipe 13 whose lower open end is closed with the cap 14. At the same time, it is blown into the de-energizing pipe 16 from each of the blow-off ports 15 opened at a plurality of locations around the blow-off pipe 13, and collides with the inner wall surface of the de-energizing pipe 16. After being sufficiently de-energized by
Only the western part of the extinguishing agent powder is inside the internal auxiliary container 20.
In addition to being stored and deposited within the
From the nonflammable high-pressure gas components, only the extinguishing agent powder component is removed from the deaerator 6 by the internal filter 19 and escapes to the outside, thereby suppressing the increase in pressure within the recovery device body 1.

Here, since the blowing pipe 12 is disposed on the horizontal body via a bent pipe 11 such as an elbow, the tip of the jet nozzle 22 can be inserted from the horizontal direction, and the powder fire extinguisher 21 can be used in the correct posture, and can also be made of rubber or soft synthetic resin, which can maintain the blowing tube 12 in a predetermined shape, for example.
By forming a relatively flexible material into a flat tube shape, it becomes easy to insert the tip of the blowing nozzle 22. By holding it together in your palm, you can prevent radiation from leaking to the surrounding area.

In other words, in this way, the dry powder fire extinguisher 21 can be tested and inspected, and during this operation, harmless, inert, nonflammable high-pressure gas is used for the outside, that is, the surrounding area of the execution place in this case. Although the components escape, the extinguishing agent powder components can be stored and deposited in the internal auxiliary container 20 or at least in the recovery device main body 1 and recovered, and the extinguishing agent powder components cannot be disposed of around the extinguishing agent powder components as in the conventional case. This eliminates the problem caused by radiation.

Furthermore, when the lid 2 is removed, the blowing device 4 and the deaerator 6 attached to the lid 2 are also removed from the collector body 1 at the same time, and the interior of the collector body 1 becomes empty. Therefore, the collected fire extinguishing agent powder can be easily taken out by appropriate means such as turning the collector body 1 over, and the collector body 1 can also be cleaned easily. When the auxiliary container 20 is arranged in the collector main body 1, the auxiliary container 20 can be easily taken out from the collector main body 1 and the drug powder can be easily taken out.

In addition, in the above embodiment, an internal auxiliary container 20 is separately arranged inside the recovery device main body 1, but this internal auxiliary container 20 is not necessarily essential.
Of course, even if only the recovery device main body 1 is used, similar trial use and inspection operations of the powder fire extinguisher 21 can be performed.

[Effect of idea]

The drug collector of this invention is not only convenient because the main body of the drug collector can be carried by hand, but also convenient since the main body of the drug collector can be easily carried anywhere. Since the equipment and deaerator are also removed, the main body of the recovery vessel is not heavy and easy to handle. The combination of the lightness of the recovery device body and the fact that it is cylindrical with a bottom has the effect that the fire extinguishing agent powder can be easily and reliably taken out by turning the recovery device body over.
Furthermore, even if an internal auxiliary container is installed in the collector body, if the lid is removed, the blowing device and deaeration device are also removed along with the lid, so the internal auxiliary container can be easily removed from the collector body. There is an effect.
