Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for heating air inside an air membrane structure such as an air tent, air beam tent, or air wrap tent.

The air membrane structure that is the subject of this invention is an air tent, etc. that can be expanded in an inflated state by continuously replenishing fresh air forcibly from a duct leading into the structure from the outside using a blower. It is.

Therefore, when storing grains or the like in such an air membrane structure, more favorable results can be obtained by heating the inside to maintain the dry state.

Conventionally, several methods have been considered to heat the inside of an air membrane structure, but the simplest of these is
A suitable heating device was placed inside the membrane structure.

However, in these membrane structures that continuously introduce fresh air, it is extremely dangerous to use fire inside them, so they have almost never been put to practical use.

As an alternative, a heating device may be placed outside the membrane structure and the heated air emitted from the heating device may flow into the side of a duct that continues to replenish the interior of the membrane structure. There were two methods: one method was to join the air being sent inside and supply it to the inside of the membrane structure, and the other method was to directly flow heated air from the outside of the membrane structure into the inside through the side wall of the structure without going through the duct. .

However, in the former case, a relatively small amount of heated air is sucked into the large amount of air flowing through the duct, which causes the heating device to rapidly overheat in a short period of time, causing failure or breakdown. In addition, the latter requires heated air to flow in at a pressure higher than the air pressure inside the membrane structure, which requires a special blower and the like, making the entire system complicated and unsuitable. Ta.

The present invention replaces the conventional technology which had such drawbacks.
The heating device is a duct which has both ends open on the side wall of the air membrane structure, is anchored to the outside of the side wall, and is introduced into the air from one end by a rotary body containing air inside the structure and led out from the other end into the structure. , and a heater built into the duct to heat the introduced air, and the heating device is provided in the structure at a distance from the air inlet through which the air is introduced. The air inside the structure can be introduced into the duct and heated by adjusting the flow rate as necessary, and then led out into the structure again.

When this heating device is used, the installation location is outside the structure, so there is no disadvantage of reducing the space inside the structure, and it is safe in terms of fire protection. It can be selected so as not to interfere with the work by taking into account the place where products come in and out, etc., and is installed away from the air inlet of the duct that brings air from the outside, so it can flow in a large amount of air at a relatively high speed. It has many advantages, such as not being affected by overheating of the heater.

The present invention will be described below based on embodiments with reference to the drawings.

FIG. 1 is a schematic plan view of an air tent, which is a type of air membrane structure to which the present invention is applied.

The structure 1 is expanded and expanded into a generally hemispherical shape.

Reference numeral 2 represents an air inlet for introducing air from the outside, and 3 represents an entrance having a parant store 3a and a truck entrance 3b.

4 shows a heating device which is a characteristic part of the present invention.

The heating device 4 includes a duct 5 and a rotating body 6 built in the duct.
and a heater 7.

The duct 5 is attached to the outside of the side wall of the structure 1 with both ends 5a and 5b open, and air inside the structure is introduced from one end 5a (arrow 8a) and led out from the other end 5b (
Arrow 8b).

The rotating body 6 introduces air at an appropriate flow rate and flow rate into the duct, and also guides it out of the duct.

Further, the heater 7 heats the introduced air to an appropriate temperature.

The rotational speed of the rotating body 6 and the temperature of the heater 7 can be freely adjusted inside or outside the structure, and the rise and fall of the air inside the structure can be controlled.

Next, it is necessary that the air inlet 2 and the heating device 4 be separated from each other so as not to be affected by an air flow from the outside introduced through the air inlet 2.

FIG. 2 is a schematic perspective view of an air beam tent, which is a type of air membrane structure, and has a roof body 11 formed by connecting tubular inflatable bodies with a circular cross section. It will be delivered and installed.

The present invention is also applicable to this structure, and a duct 13 that is attached to the side wall with both ends open and a heater 14 built into the duct are provided.

Furthermore, although not shown, the heating device according to the present invention can be similarly provided in an air wrap tent at a position separated from the air inlet.

In these tents, the interior of the tent is heated by heated air within the roof body.

In addition, when it snows, it has a remarkable effect on preventing snow from accumulating on the upper part of the roof.

Since the present invention is based on the above configuration, the temperature inside the structure can be freely adjusted almost independently of the air flow from the outside, and overheating does not occur.
Since the heating device is installed outside the structure, there is no reduction in effective space, and since the heater is outside the structure, there is a high degree of safety against fires. It is an extremely useful heating device for air membrane structures, having many advantages such as being able to arbitrarily control the speed of the air flow introduced and extracted and the internal temperature of the structure.
