Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fire hose drying apparatus for drying a fire hose wet by water discharge.

[0002]

2. Description of the Related Art Conventionally, there are a method of drying a fire hose wet by discharging water, a method of drying naturally by drying in the sun, and a method of forcibly drying using a special fire hose dryer.

In the drying method using sun drying, a wet fire hose is hung on a fire watch tower or other dedicated towers for drying. In this drying method, the degree of drying depends on the weather. It takes time to dry. The drying becomes uneven. Due to the appearance of high-rise buildings, there is a fire station without a fire tower, and it is not possible to hang a long fire hose, which is about 20m long, to dry it. Due to various problems such as these, recently, a method of forcibly drying using a dedicated fire hose dryer has been adopted.

[0004] A fire hose dryer, which is widely used at present, dehumidifies and dryes the outside of the hose by a low-temperature dehumidification method (refrigerator method), while drying the inner surface of the hose by a blower method. By drying the outside simultaneously by each of the above methods, the wet hose can be dried by 90% or more in about 2-3 hours.

[0005]

However, the above-mentioned conventional fire hose dryer uses both a low-temperature dehumidifying dryer for drying the outer and inner surfaces of the hose at the same time and a blower dryer. There has been a problem that the size and price are increased.

In addition, since the above-mentioned conventional dryer is large and heavy, it is very difficult to secure a passage for carrying in the product, and a considerably large installation space is required for installation. Large winding trolley dedicated for drying fire hoses (for example, 1,200 W x 1,500 L x 1,500 H)
Or a hose carrier (for example, 850W × 1,650L ×
1,755H). It is 6 fire hoses in a mass
Since 10 to 10 tubes are set and dried at the same time, drying and carrying in / out of each hose cannot be performed. After drying, the hoses cannot be stored in the fire hose carrier equipped with the fire truck unless the hoses are refolded one by one. There were various problems.

Therefore, the technical problem of the present invention is that the firefighting hose is dried in a relatively short time because the structure is simple and the price is low, and the product can be easily carried in and installed. It can dry and carry in and out fire hoses one by one without using large and cumbersome take-up trolleys or trolleys. It is an object of the present invention to provide a fire hose drying device devised so that it can be stored in the fire hose.

[0008]

Means taken by the present invention to solve the above-mentioned technical problems are as follows.

[0009] A far-infrared radiation dryer having a combustion gas heat radiating tube installed therein is installed in a drying chamber, and is placed on a drying shelf provided in the drying chamber by the far-infrared radiation heat radiated from the dryer. Or a fire hose drying device configured to dry the suspended fire hose,

(1) A hot air duct for taking in hot air which is heated by the heat radiation tube and ascending by the intake of a circulating fan is connected to an upper portion of the dryer, and the hot air is connected to the hot air duct. A hot-air blowing pipe for blowing hot air sent by the circulation fan toward the fire hose placed on or suspended from the drying shelf is connected to a tip end of the duct. (Claim 1)

(2) The fire hoses are converged into a folded or wound state with a spacer having a substantially corrugated cross section between them, and the converged fire hoses are converged. It shall be configured to be placed on the drying shelf in the drying room and dried. (Claim 2)

(3) The fire hoses are housed in a dedicated drying basket while being folded many times with spacers each having a corrugated cross section between them, and the drying basket is dried in a drying chamber. The fire hose must be placed on a shelf and be configured to dry. (Claim 3)

(4) The entire shape of the drying basket in which the fire hose is stored and dried so that the dried fire hose can be loaded into the fire hose carrier without being refolded. To be formed in a box shape.
(Claim 4)

According to the means according to claim 1 described in the above (1), far-infrared radiation dryer radiates far-infrared radiation heat from the far-infrared radiation dryer to the fire hose suspended or placed on the drying rack. Then, the hot air heated by the heat radiation tube of the dryer is blown out toward the fire hose by a circulation fan, so that the fire hose is dried with both the radiant heat and the hot air. It can be completed in a relatively short time, and it can be assembled simply by combining a far-infrared radiation dryer used for clothes drying and heating equipment, a circulation fan, and ducts. It can be manufactured at extremely low cost, and can easily carry in and install products.

[0015] In addition, according to the means described in the above (1), the wet fire hose is placed on or hung on a drying shelf provided inside the drying chamber without using a winding cart or a trolley. By doing so, the fire hose can be dried with a relatively simple operation, and drying and carrying in and out of each hose can be performed.

According to the means according to claim 2 described in the above (2), since the entire outer surface area of the hose is made the heat transfer area at the time of drying the hose by the interposition of the spacer, the drying time of the wet fire hose is reduced. Drying can be performed in a shorter time (about 2 to 3 hours) of about 1/5 as compared with the case where no spacer is interposed.

According to the means of claim 3 described in the above (3), the wet fire hose is folded and stored in the drying basket several times with the spacer interposed therebetween, and
Since the drying baskets are placed on the drying racks for drying, by stacking the drying baskets on the drying racks, a number of fire hoses can be dried neatly at one time, and the fire hoses can be taken out in units of the drying basket. Since the fire hose can be inserted, handling of the fire hose at the time of carrying in and out can be simplified and labor can be saved.

According to the means according to claim 4 described in the above (4), the fire hose that has been stored and dried in the drying basket can be removed from the fire hose carrier without being refolded by simply removing the spacer. Since it is possible to store the fire hose after drying, it is possible to simplify and save labor of handling the fire hose after drying.

As described above, the above (1) to
By solving the above technical problem by means of (4),
The problem of the conventional technique can be solved.
