Description

DETAILED DESCRIPTION OF THE INVENTION (a) Industrial Application Field The present invention relates to a reduced pressure heating and heat generation device that can be used as a heat source and drying source for drying plants, grains, animals, human bodies, granules, etc., indoor heating, etc. Regarding the method.

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

On the other hand, the present inventors have
No. 7-19583, JP-A No. 57-55378 and 7
In a series of subsequent inventions, such as Kokai No. 55379/1983 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. While maintaining this equilibrium state, the rotating action of the rotating body is continued to promote the frictional action with the air to generate frictional heat, and this frictional heat heats the inside of the hollow chamber. This is a heating method that uses the rotating action of a rotating body to forcibly suck the air inside a sealed hollow chamber and exhaust it to the outside, reducing the pressure in the room and keeping the pressure difference between the inside and outside at a constant equilibrium state. At the same time, while maintaining this equilibrium state, the rotating action of the rotating body is continued to promote frictional action with the air and generate frictional heat.

This is a reduced-pressure balanced heating method that uses this frictional heat to heat the inside of the hollow chamber, and then feeds outside air into the hollow chamber manually or automatically, and consumes less energy such as electricity than conventional heating methods. have an effect.

In addition, the present inventor proposed a pressurized equilibrium heating method in JP-A No. 57-127779, and found that if an exhaust port is provided that is lower than the exhaust capacity of the rotating body, the intake gas will be forced to be discharged to the outside. It has also been found 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 disclosed in Japanese Patent Application No. 58-126256 ``Hot Air Method and Apparatus'' that a rotating device has a gas inlet and a gas outlet and rotates with a gas suction capacity greater than the gas suction leg of the gas inlet. A hollow body with an airtight structure,
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. The hollow bodies are connected in sequence by connecting the gas outlet and gas inlet of each hollow body,
A method to create hot air was proposed.

(c) Problems to be solved by the invention The inventor discovered that when multiple hollow bodies are connected in a hermetically sealed manner, even though the spaces between the hollow bodies or the walls of the hollow bodies become high temperature, For example, the temperature of the wall inside a sealed storage (hollow room) that is warmed by the gas exhausted from the mouth will not increase, and the temperature will not rise, and the temperature will be highest near the exhaust port of each hollow body. I found out.

However, drying and heating generally do not require very high temperatures.

Furthermore, the inventor found that after reaching a reduced pressure equilibrium state, there is no difference in heat generation effect even if the gas inlet of the hollow body has a smaller diameter, and that by making the gas inlet smaller, the supplied current can be reduced. It was found that similar heat generation occurred even when This invention is based on these findings, which are assumed to be due to the influence of gas flow and gas density under reduced pressure equilibrium conditions.

B) Means for Solving Problems This invention has a gas inlet and a gas outlet, and rotates with a gas suction capacity greater than the gas suction capacity of the gas inlet, and rotates a rotating body while maintaining a constant pressure equilibrium state. In a swirling convection heat generating device consisting of a hollow body having a rotating body that generates heat by rotational action in a region, a straightening plate having an opening smaller in diameter than the gas inlet of the hollow body is detachably attached to the gas inlet. A reduced pressure heating heat generating device, which has a gas inlet and a gas outlet, rotates at a large capacity for gas Φ, which is larger than the gas suction capacity of the gas inlet, and maintains a constant pressure equilibrium state in the rotating region of the rotating body. A reduced-pressure heating and heat-generating device in which a plurality of airtight hollow bodies each having a rotating body that generates heat through rotational action are provided, and the gas outlet and gas inlet of adjacent hollow bodies are connected via a box having a gas outlet. 4, a reduced pressure heating heat generating device, a gas inlet and a gas exhaust, characterized in that a [j; A rotating body that has an outlet, rotates with a gas suction and discharge capacity greater than the gas suction capacity of the gas inlet and the gas discharge capacity of the gas outlet, and generates heat by rotational action in the rotation area of the rotor while maintaining a constant pressure equilibrium state. In a reduced pressure heating heat generating apparatus af-, a plurality of hollow bodies having an airtight structure are provided, and the gas outlet and gas inlet of adjacent hollow bodies are connected via a gas outlet having a gas outlet. The present invention relates to a reduced pressure heating and heat generation device characterized in that an adjusting plate having an opening smaller in diameter than the gas inlet is removably attached to the gas inlet.

(E) When the electric motor is driven with the action adjusting plate in the released state, gas flows into the hollow body.

At this time, the opening area of the gas inlet is set to be less than the gas suction capacity of the rotating body installed in the corresponding hollow body, or the opening area of the gas inlet is also limited to be smaller than the opening area of the gas outlet, so the rotating body The amount of gas sucked in is smaller than the gas discharged by the hollow body, and the pressure in the rotation region R of the rotating body 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 gradually increases, but at the point when the pressure difference reaches this pressure difference, it is almost balanced in relation to the gas flowing into the vicinity of the rotational region R. condition is reached and this constant pressure condition is maintained. The pressure difference between the inside and outside of the rotating 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, the size of the minute gap g, etc. This equilibrium and constant pressure state is maintained as long as the rotation of the rotating body continues. In this equilibrium state, air stagnation occurs in the rotating region R of the rotating body, and a frictional effect occurs between the rotating body and the accumulated gas. As the friction continues, 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 reason is that the gas sucked into the hollow body (6) a will be forcibly discharged to the outside. , it exhibits a kind of pressurizing effect at the gas outlet, and is accompanied by the generation of rice heat, making it possible to further increase the exhaust temperature.

When hollow bodies are connected, the same effect will occur with other hollow bodies. When a box is provided between the hollow bodies, a part of the gas discharged from the hollow body is discharged into the box and further discharged from the gas outlet of the swirl box to the outside of the swirl box, thereby heating and drying the room outside the hollow body. Therefore, the exhaust side of each hollow body does not overheat. When the hollow body reaches a reduced pressure equilibrium state, the adjusting plate is brought into contact with the gas suction port, and even if the gas suction port is made smaller in diameter, heat generation occurs in the same way. Even if the supplied current is further reduced in this state, heat generation will occur in the same way.

This will be explained according to FIG. 4.

The capacity decreases from the intake port side to the exhaust port side. That is, in this embodiment, the adjacent electric motors G11a, (11)b, and αυC that rotate each rotating body are controlled so as to take a smaller load current on the exhaust side than on the intake side. When hollow bodies are connected in series and the rotating bodies installed in each hollow body are rotated by motors connected in parallel, even if the exhaust side electric motor is controlled to take a smaller load current than the intake side electric motor, This is because it was found that the same heat generation drying efficiency was obtained when controlling to take the same load and current. As a control means, between adjacent electric motors,
A means to make the capacity of the electric motor on the exhaust side smaller than that on the intake side,

When each electric motor is driven with b, Q3)c removed from each gas inlet (2), gas such as air flows from the inlet (2) to the intake path (

At this time, the gas inlet ( 7) The opening area of A is the rotating body (10) installed in the corresponding hollow body (6) a. Since the opening area of the rotating body GOI is limited to be smaller than the opening area of The pressure is reduced compared to , and the pressure of the hollow body as a whole is also reduced. When the difference is reached, an approximately equilibrium state is reached in relation to the gas flowing into the vicinity of the rotating head R, and this constant pressure state is maintained. The pressure difference between the inside and outside is determined by the magnitude of the rotational suction and exhaust force of the rotating body (11), the size of the opening area of the gas inlet (7) a, the size of the gap g, etc. The constant pressure state is maintained as long as the rotating action of the rotating body fJ (ea continues).In this equilibrium state, the rotating body fi

13) Discharge from a to the outside of the hollow body. Gas outlet (8)
If the opening area of a is set to a smaller exhaust capacity than the exhaust capacity of the rotating body θ1a, the gas sucked into the hollow body (6) a will be strongly discharged to the outside. The outlet 18) a exerts a four-fold pressurizing action, and generates compression heat, making it possible to further raise the exhaust gas temperature. The same effect is performed for the other hollow bodies (6)b and (6)C. A part of the gas discharged from the hollow bodies 16)a, (6)b is discharged to the swirling boxes (9)a, (9)b, and then to the gas outlet f121a, 0'' of the swirling box.
3b, (121c, (13d) is discharged into the room, circulated inside the room, heated and dried, so the exhaust side of each hollow body does not overheat (, the time to raise the hollow chamber (11 to about 600, for example, is shortened) When the hollow body reaches a reduced pressure equilibrium state, the adjustment plates (13a, (13)b, (13)

Let C be the small diameter. Even if the supplied current is reduced at the same time, heat generation continues in the same way. This seems to be because even in a reduced pressure equilibrium state, inhaling through the gas inlet with the same diameter as before causes a loss.

Gas that is not discharged into the hollow chamber (1) passes through the exhaust passage (5), exchanges heat with the intake gas on the way, and is then exhausted from the exhaust port (3). The exhaust port may collect exhaust gas from two or more hollow bodies.The material to be dried I is dried at a low temperature by heating and reducing the pressure in one chamber.

(G) Effects of the Invention Therefore, according to the present invention, it becomes possible to generate heat and heat drying more efficiently. Therefore, it is possible to efficiently dry animals and plants, such as grains, dry treatments for the human body, and dry granular materials.
