FIRE HOSE DRYING METHOD AND APPARATUS

This invention relates to a fire hose test pressure method according to the preamble of claim 1 and to a device according to the method.

In known fire hose drying apparatuses, where the hose can be dried by blowing warm air into the hose, the hoses are pulled straight.

The downside to the fire hose dryers currently in use is that they require a lot of space because they have straight hoses, so the space requirement is at least the length of the hose. Generally, old fire stations do not have large facilities available, so they cannot purchase new drying equipment at all. Em. as a result, the hoses may, in the worst case, not be dried, which will significantly shorten their service life.

It is an object of the invention to provide a method for drying a fire hose and a device according to the method by which the drying of a fire hose can be carried out in a substantially smaller space.

The foregoing disadvantages can be overcome and the object described above is achieved by a fire hose drying method according to the invention and a device according to the method, characterized in what is defined in the characterizing parts of the claims.

One of the main advantages of the invention is that the invented fire hose drying method and apparatus provide a small space for drying the fire hose. As a result, the equipment can also be * 113346 2 located in old, narrow fires. That is, all firing plants are allowed to dry the hoses and thus their service life is increased. It will be obvious to a person skilled in the art that the method of drying the fire hose according to the invention and the device according to the method achieve overall economic savings.

The invention will now be described in detail with reference to the accompanying figure.

Figure 1 is a top plan view of an apparatus for drying a fire hose according to the invention.

The figure shows the following parts of the system. Fire Hose 1, Connector 2, Drying Point 3, Center 4, Hose End 5, Protective Cover 6, Blower 7, Duct 8, and Deaeration Unit 9.

In the apparatus shown in the figure, one or more drying hoses 1 are wound onto the apparatus. Air is blown through the central portion 4 of the roller to the drying hose (s) 4 located in the drying locations 3. One or more drying locations 3 of the hoses 1 of the device are preferably rotatably rotatable. The figure shows that one or more drying locations 3 consist of a plane to which the fire hose 1 is rotatable. Further, the figure shows that the drying areas 3 are inside a protective housing with an opening and closing protective cover 6. Thanks to the protective housing, the drying process is fast and moisture does not spread to other areas of the fire station.

In order to reach the hose 1 to be dried, at least one end of the fire hose 1 is attached by a connector 2 to the central part 4 to direct the drying air to the fire hose 1. The damp air 111146 3 exits the open end of the fire hose 1 and

In the figure, air is blown into the central part 4 of the fire hose through a duct 8 by a fan 7, the duct 8 being preferably located in connection with the bearing of the drying places 3, i.e. in the center of rotation.

In the figure, the humidified air outlet member 9 is also located in the center of rotation of the imaging locations 3.

The humidified air outlet means 9 can, if desired, suck up the moist air by means of a fan, thereby accelerating the air circulation.

The apparatus may also be provided so that the drying points 3 can be rotated in both directions by a rotating member such as, for example, an electric motor, a pneumatic motor, a hydraulic motor or the like.

All parts of the apparatus can be made from known raw materials by known methods.

The drying takes place as follows: the end of the hose 1 is connected to the air blowing connector 2 and the hose 1 is rolled into the drying place 3 around its central part 4. When the hose 1 has been rolled to the device, a stopper plug, which restricts the flow of air through the hose, is attached to the end of the hose 5, thereby providing a so-called hose with the resulting overpressure. bulging, where drying is most effective. One or more hoses 1 may be wound into the device. The closed drying space is obtained by closing the protective cover 6. The air 7 is blown by the fan 7 through the duct 8 into the central part 4, from which it enters the hoses 4 113546 through the air blowing fittings 2. If desired, air can also be blown into the lower part of the drying space of the hoses, thereby accelerating, e.g. drying of the hoses. The air passing through the hoses 1 and blown into the drying space is discharged through one or more deaeration means 9. In the figures, the deaeration member 9 consists of a tube, but can be replaced, for example, by openings made at appropriate points, provided that the drying environment is such as to allow moisture to enter the environment. If necessary, the blown air is preheated. After drying, the protective cover 6 is opened and the hoses 1 are pulled out of the drying points 3 in the figures from the circular flange-shaped planes. When pulled, the drying points 3 rotate so that the hose easily leaves. When the hose is pulled out of the drying position, the end of the hose is disconnected from the air blow connector 2 and the dried hose is completed.

It will be apparent to one skilled in the art that the invention is not limited to the above alternatives, but that many modifications are possible within the scope of the inventive concept defined in the appended claims.
