Description

[Detailed Description of the Invention] (a) Field of Industrial Application This invention provides a heat generating system using reduced pressure heating that can be used as a heat source for drying plants, grains, animals, human bodies, granular coatings, indoor heating, etc., and as a drying source. Apparatus and method.

(b) Prior Art As conventional methods for heating devices and drying devices, devices using burners using gas or petroleum as raw materials and electric resistance as a heat source are known.

On the other hand, the present inventor has
No. 57-19583, JP-A No. 57-55378, and JP-A No. 57-57
In a series of subsequent inventions such as No. 55379 and Japanese Patent Publication No. 58-21185, a reduced pressure equilibrium heating method and a drying method or apparatus using the method were proposed.

The basic technology is that the air inside a sealed hollow chamber is forcibly sucked in by the rotation of a rotating body and exhausted to the outside, reducing the pressure inside the room and keeping the pressure difference between the inside and outside at an approximately constant equilibrium state. and maintaining this equilibrium state, the rotating action of the rotating body is continued to promote frictional action with the air to generate frictional heat, and this frictional heat heats the inside of the hollow chamber. This method further includes forcibly suctioning the air in a sealed hollow chamber by the rotation of a rotating body and exhausting it to the outside, reducing the pressure in the chamber and keeping the pressure difference between the inside and outside in a substantially constant equilibrium state. While maintaining this equilibrium state, the rotating action of the rotating body is continued to promote frictional action with the air to generate frictional heat, and this frictional heat heats the inside of the hollow chamber, and further, manually or automatically operates the inside of the hollow chamber. This is a reduced-pressure equilibrium heating method in which outside air is supplied through the air, and has the effect of consuming less energy such as electric power than conventional heating methods.

The present inventor also proposed a pressurized equilibrium heating method in JP-A No. 57-127779, and found that if an exhaust port with a capacity lower than the exhaust capacity of the rotating body is provided for exhaust, the intake gas will be forced to be discharged to the outside. It was also discovered that the compressor exhibits a kind of pressurizing effect, and therefore generates heat of compression, increasing the temperature more effectively and producing warm air.

The inventor further submitted the patent application No. 58-126256 (Japanese Patent Application No.
No. 60-20059) "Hot air method and apparatus", a hollow body with an airtight structure having a gas inlet and a gas outlet, and a rotating body that rotates with a gas suction capacity greater than the gas suction amount of the gas inlet. We proposed a method to create multiple hot air streams in succession by sequentially connecting the gas outlet and gas inlet of each hollow body.
Further, in the same application, a plurality of rotating bodies having a gas intake and discharge capacity larger than the gas intake capacity of the gas intake port and/or the gas discharge capacity of the gas discharge port are included in a hollow body of an airtight structure having a gas intake port and a gas discharge port. We proposed a method to create hot air by connecting hollow bodies in series by sequentially connecting the gas outlet and gas inlet of each hollow body.

(c) Problems to be solved by the invention The inventor discovered that when hollow bodies are connected in a sealed manner in multiple stages, even though the spaces between the hollow bodies or the walls of the hollow bodies become high temperature, For example, the temperature inside a sealed storage (hollow chamber) that is heated by gas exhausted from the mouth does not rise as the temperature of the hollow body wall increases, and in each hollow body, the temperature near the exhaust port of each hollow body It was found that the temperature was the highest.

The inventor has also found that when a higher temperature is desired using a reduced pressure heating heat generating device, some electric motors may lack heat resistance, which may be an impediment to obtaining a higher temperature.

The inventor further discovered that it is not necessary to rotate all the rotating bodies as the temperature rises or after the temperature rises, and that this can reduce the energy used.

The purpose of this invention is to further improve the efficiency of the technical contents already proposed by the present inventor.

(d) Means for Solving the Problems These inventions have a gas inlet and a gas outlet, and rotate with a gas suction capacity greater than the gas suction capacity of the gas inlet, and maintain a constant pressure equilibrium state while rotating the rotating body. A reduced-pressure heating and heat-generating device characterized in that a plurality of airtight hollow bodies each having a rotating body that generates heat due to rotational action in a rotating region is provided, and each rotating body is driven by the same power. and a rotating body that has a gas inlet and a gas outlet, rotates with a gas suction capacity greater than the gas suction capacity of the gas inlet, and generates heat by rotational action in the rotating region of the rotor while maintaining a constant pressure equilibrium state. A plurality of hollow bodies with an airtight structure are provided, each rotating body is driven by the same power, and the gas discharged from the gas outlet of the hollow body is introduced into the gas outlet and gas inlet of the adjacent hollow body, A reduced pressure heating heat generating device characterized in that the device is connected via a box having a gas outlet for discharging a portion of gas to the outside.
It has a gas inlet and a gas outlet, and rotates with a gas inlet and outlet capacity greater than the gas intake capacity of the gas inlet and the gas discharge capacity of the gas outlet, and operates in the rotating region of the rotating body while maintaining a constant pressure equilibrium state. A reduced-pressure heating and heat-generating device characterized in that a plurality of airtight hollow bodies each having a rotating body that generates heat due to rotational action are provided, and each rotating body is driven by the same power. and,
It has a gas inlet and a gas outlet, and rotates in the rotating region of the rotating body while maintaining a constant pressure equilibrium state by rotating with a gas inlet and outlet capacity that is greater than the gas inlet capacity of the gas inlet and the gas outlet capacity of the gas outlet. A plurality of airtight hollow bodies each having a rotating body that generates heat due to its action is provided, each rotating body is driven by the same power, and the gas discharge port and gas inlet port of the adjacent hollow body are discharged from the gas discharge port of the hollow body. To provide a reduced-pressure heating and heat-generating device, which is characterized in that it is connected via a box having a gas outlet for introducing a gas and discharging a part of the gas to the outside.

(e) Effect When the power is driven, gas flows into the hollow body on the side closest to the intake port.

At this time, the opening area of the gas suction port should be less than or equal to the gas suction capacity of the rotating body installed in the corresponding hollow body.
Alternatively, since the opening area of the gas inlet is also limited to be smaller than the opening area of the gas outlet, the amount of gas inhaled is smaller than the gas discharged by the rotating body, and in the rotation area R of the rotating body. The pressure is reduced compared to other parts, and the pressure of the hollow body as a whole is also reduced. The pressure difference between the rotation region R and other parts and the pressure difference with the outside air inside the hollow body gradually increases, but when a certain pressure difference is reached, the difference in pressure between the rotation region R and the other parts and the outside air inside the hollow body gradually increases. An equilibrium state is reached and this constant pressure state is maintained. The pressure difference between the inside and outside of the rotation region R in this equilibrium state and constant pressure state is determined by the magnitude of the rotational suction and exhaust force of the rotating body, the size of the opening area of the gas inlet,
Although determined by the size of the minute gap g, etc., this equilibrium and constant pressure state is maintained as long as the rotating action of the rotating body continues. In this equilibrium state, a stagnation phenomenon of air occurs in the rotation region R of the rotating body, and the frictional action continues repeatedly between the rotating body and the stagnant gas, so that frictional heat is generated and the temperature gradually rises. The warm air heated by this frictional heat passes through a small gap g and is discharged from the gas outlet to the outside of the hollow body.If the opening area of the gas outlet is set to a smaller exhaust capacity than the exhaust capacity of the rotating body, the hollow body Since the gas sucked into the compressor is forcibly discharged to the outside, a kind of pressurizing effect occurs at the gas outlet, and heat of compression is generated.
It is possible to further increase the exhaust temperature. Similar effects occur with other hollow bodies. A part of the gas discharged from the hollow body is discharged into the box and further discharged outside the box from the gas discharge port of the box, thereby heating and drying the interior of the room outside the hollow body. Therefore, the exhaust side of each hollow body is not overheated, and the time for heating and drying the outside of the hollow body is shortened.

When it is not necessary to drive all the rotating bodies, only a specific rotating body is rotated.

(F) Embodiment The following is a first section showing a front cross section of an embodiment of the present invention.
The explanation will be given with reference to the drawings, FIG. 2 showing a partial cross-section of the right side, and FIG. 3 showing a partially enlarged front view of another embodiment.

1 is a hollow chamber serving as a drying chamber. The hollow chamber 1 consists of a sealable box. 2 is an intake port, and 3 is an exhaust port. Both the intake port 2 and the exhaust port 3 open into the hollow chamber 1. 4 is an intake path, and 5 is an exhaust path, which are continuous from the intake port 2 and the exhaust port 3, respectively. The intake passage 4 and the exhaust passage 5 form a heat exchange mechanism in the middle. 6a and 6b are hollow bodies having an airtight structure. Each hollow body has two openings: a gas inlet 7a, 7b and a gas outlet 8a, 8b having a larger opening area than the gas inlet 7a, 7b. The gas inlet 7a of the hollow body 6a on the intake side is connected to the intake passage 4, and the hollow body 6b on the exhaust side is connected to the air intake passage 4.
The gas outlet 8b of the hollow body 6a on the intake side is connected to the exhaust passage 5, and the gas outlet 8a of the hollow body 6a on the intake side is connected to the hollow body 6 on the exhaust side.
It is connected to the gas inlet 7b of b through the box 9a. Two hollow bodies may be connected as shown in FIG. 1, but as shown in FIG.
Three groups or four or more groups may be connected via b.

Reference numerals 10a, 10b, and 10c are rotating bodies, each of which is composed of rotating blades such as a propeller fan or a Shirotsuko fan. The rotating bodies 10a, 10b, 10c have a hollow chamber 1
Shaft 12 connected to electric motor 11 installed outside
It is possible to rotate in a direction in which gas can be sucked in from the gas intake ports 7a, 7b, and 7c and gas can be discharged from the gas discharge port. Other power instead of the electric motor 11,
For example, an internal combustion engine such as a gasoline engine or an external combustion engine may be used. The power may be driven directly or via a transmission means such as a V-belt. Clutches 13a and 13b are capable of connecting and disconnecting the shaft. clutch 13a,
The installation position of 13b is not particularly limited. A transmission may be attached to the clutches 13a, 13b so that the rotational speed of each rotating body can be adjusted.

g is the inner wall of the hollow bodies 6a, 6b, 6c and the rotating body 1
A minute gap formed by 0a, 10b, 10c,
R is the rotation area of the rotating body. The rotating body 10a installed in the corresponding hollow body,
The gas suction ports 7a, 7b,
It is necessary to set the opening area of 7c.

In this embodiment, the rotating bodies 10a, 10b installed in the corresponding hollow bodies,
The opening area of the gas exhaust port 10 is set so that the gas exhaust capacity of the gas exhaust port 10c during normal rotation is greater.

The boxes 9a, 9b each have hollow bodies 6a, 6b,
Gas outlet 1 which is provided with an airtight structure between the gas outlet and the gas inlet of 6c and whose opening area can be adjusted.
4a, 14b, 14c, and 14d are opened. The total opening area of the gas discharge ports of each rotating box is formed to be smaller than the gas discharge capacity of each hollow body.

Therefore, when the objects to be dried 15 such as plants, grains, animals, human bodies, granules, painted objects, etc. are installed in the hollow body and each electric motor is driven, gases such as air pass through the air intake path 4 from the intake port 2 to the hollow chamber 1 on the way. The gas inside is mixed and flows into the hollow body 6a on the nearest intake port side through the gas intake port 7a.

At this time, the opening area of the gas inlet 7a is limited to less than the gas suction capacity of the rotating body 10a installed in the corresponding hollow body 6a, and the opening area of the gas inlet 7a is limited to smaller than the opening area of the gas outlet 8a. Because there are
Compared to the gas discharged by the rotating body 10a, the amount of gas taken in is small, and the pressure in the rotation region R of the rotating body 10a is reduced compared to other parts, and the pressure in the hollow body as a whole is also reduced. The pressure difference between the rotational region R and other parts, and the pressure difference between the hollow interior and the outside air will gradually increase, but once a certain pressure difference is reached, the pressure difference will approximately decrease due to the relationship with the gas flowing into the vicinity of the rotational region R. An equilibrium state is reached and this constant pressure state is maintained. The pressure difference between the inside and outside of the rotating region R in this equilibrium state and constant pressure state depends on the magnitude of the rotational suction and exhaust force of the rotating body 10a, the size of the opening area of the gas suction port 7a, the size of the minute gap g, etc. However, this equilibrium
The constant pressure state is maintained as long as the rotating action of the rotating body 10a continues. In this equilibrium state, the rotating body 10
Air stagnation phenomenon occurs in the rotational region R of a, and the rotating body 1
Since the frictional action continues repeatedly between Oa and the accumulated gas, frictional heat is generated and the temperature gradually rises. The warm air heated by this frictional heat passes through a small gap g and is discharged from the gas discharge port 8a to the outside of the hollow body. If the opening area of the gas outlet 8a is set to a smaller exhaust capacity than the exhaust capacity of the rotating body 10a, the gas sucked into the hollow body 6a will be forcibly discharged to the outside. 8a exhibits a kind of pressurizing effect and generates compression heat, making it possible to further increase the exhaust temperature. Other hollow bodies 6
A similar effect is performed in b and 6c. hollow body 6
A part of the gas discharged from a, 6b is discharged to the boxes 9a, 9b, and further to the gas discharge ports 14a, 14b, 14c, 14d, 14e, 1 of the boxes.
It is discharged indoors from the 4th floor, circulated indoors, heated, and dried.

Gas exhaust ports 14a, 14b, 14c, 14d,
14e and 14f may be closed depending on temperature conditions, etc.
Gas does not need to be discharged. When temperature conditions do not require driving all rotating bodies, clutch 13
By cutting a and 13b, the rotating body to be driven is selected.

The gas that is not discharged into the hollow chamber 1 passes through the exhaust passage 5 and exchanges heat with the intake gas on the way, and then is exhausted from the exhaust port 3. The exhaust port may combine exhaust from two or more hollow bodies. The material to be dried 13 is dried by heating and reducing the pressure in the room.

(g) Effects of the invention Therefore, with this invention, less electric current is required, and it becomes possible to efficiently generate heat and perform heating drying. Therefore, plants and animals, such as drying of grains,
It is possible to efficiently perform dry treatment for the human body, drying granular materials, drying painted materials, etc. Since each rotating body is driven by the same motor, it is possible to install the motor outside the hollow chamber, and the heat resistance of the motor can be improved. There is no need to consider this, and it is possible to obtain higher temperatures. Furthermore, this invention can be used to produce remarkable effects when used to grow fungi, mushrooms, bulbous plants, and other plants under heating. That is, for example, under reduced pressure heating under appropriate temperature and humidity conditions,
By placing shiitake mushroom spore-bearing wood in a hollow chamber, it is possible to obtain about 5 to 10 times the yield compared to the conventional method. It is boiled in winter with the cap wrapped inside. It is also possible to have a remarkable effect on growing other mushrooms, fungi, daikon radish, bean sprouts, and other plants. These effects on growth are thought to be due not only to heating but also to the rarefied air condition obtained through reduced pressure conditions, and hollow chambers with these conditions can be used as a kind of field. .
