Description

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

(B) Prior Art As conventional methods for heating devices and drying devices, devices using gas, gas, oil, and electrical resistance as a heat source are known.

On the other hand, the present inventor has disclosed Japanese Patent Application Laid-Open No. 57-19582, Japanese Patent Application Laid-open No. 57-19583, '? ? JP-A-57-55378 and JP-A-57-55379,! (♀Proposed a drying method or device, etc.)

The basic technology is that the air inside a sealed hollow chamber is forcibly sucked in by the rotating action of the rotor and evacuated to the outside, and the inside of the room is pressurized to keep the pressure difference between the inside and outside at a constant level. Depressurization is maintained in an equilibrium state, and 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. This is an equilibrium heating method, and the air in the sealed hollow chamber is forcibly sucked in by the rotation of a rotating body and exhausted to the outside, reducing the pressure in the room and bringing the pressure difference between the inside and outside to a nearly 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. This is a reduced pressure balanced heating method that automatically supplies outside air, and has the effect of consuming less energy such as electric power than conventional heating methods.

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. The inventor also found that the compressor exhibits a kind of pressurizing action, and therefore generates compression heat, increasing the temperature more effectively and producing hot air. [Method and device], a hollow body having an airtight structure has a gas inlet and a gas outlet, and has a rotating body that rotates with a gas suction capacity larger 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.

In addition, in the same application, a plurality of rotating bodies having a gas inlet and a gas discharge port having a gas suction capacity and/or a gas discharge capacity greater than the gas discharge capacity of the gas discharge port are included in a hollow body of an airtight structure having a gas inlet and a gas discharge cap. 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.

(／→ Problems to be Solved by the Invention) The inventor discovered that when hollow bodies are connected in a hermetically 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 the temperature near the exhaust port of each hollow body is the highest. However, drying and heating generally do not require very high temperatures.

The inventor also found that when hollow bodies are arranged in tandem in multiple stages and the rotary bodies installed in each hollow body are rotated by electric motors connected in parallel, the municipal stage on the exhaust side has an intake II! Small fish F from l city 1 moving beach? Even if the current is controlled, the same heat generation and drying effect as when the same load current is controlled.
I found out that the rate is taken.

It is assumed that this is because the load on the rotating body decreases in relation to the gas flow and gas density under reduced pressure equilibrium conditions.

It has also been found that even if a portion of the exhaust air from each hollow body is discharged from between consecutive hollow bodies, the same effect still remains, albeit to a different degree.

As a method to dissect a small load current,
Possible methods include reducing the current and reducing the motor capacity.

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

(b) Means for Solving the Problems This invention has a gas suction port and a gas discharge port, rotates with a gas suction capacity greater than the gas suction capacity of the gas suction port, and maintains a constant pressure equilibrium state. PB is a hollow body with an airtight structure that has a rotating body that generates heat due to rotational action in the rotating region.
A reduced pressure heating heat generating device is provided, which connects a gas outlet and a gas inlet of an adjacent hollow body through a box having a gas outlet, and a gas inlet having a gas inlet and a gas outlet. A number of hollow bodies with an airtight structure are provided, each having a rotating body that rotates with a gas suction capacity greater than the suction capacity and generates heat due to rotational action in the rotation area of the rotary body while maintaining a constant pressure equilibrium state, and the gas in the adjacent hollow body is Connecting the outlet and the gas inlet via a box having the gas outlet,
A reduced pressure heating heat generation method characterized in that the electric motor that rotates each rotating body is controlled so that a smaller load current is taken on the exhaust side than on the intake side. 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 plurality of airtight hollow bodies each having a rotating body that generates heat due to rotational action are provided.
A vacuum heating device that connects a gas outlet and a gas inlet of adjacent hollow bodies through a box having a gas outlet. and 1 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 maintains a constant pressure equilibrium state in the rotation area of the rotating body. A plurality of airtight hollow bodies each having a rotating body that generates heat through rotation are provided, and the gas outlet and gas inlet of adjacent hollow bodies are connected via a box having a gas outlet, and each rotating body is rotated. The electric motor according to the present invention relates to a reduced pressure heating heat generation method characterized in that the exhaust gas 111+1 is controlled so as to take a smaller load current than the intake air 1[1,n.

(E) Action When the motor is pivoted, gas flows into the hollow body closest to the intake port.

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 rotation region R and other parts, and the pressure difference between the hollow interior and the outside air will gradually increase, but when they reach the pressure difference, they will be approximately balanced in relation to the gas flowing into the vicinity of the rotation region R. The pressure difference between the inside and outside of the rotating region R in this equilibrium state and constant pressure state, in which the state is reached and this constant pressure state is maintained, 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 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 discharge port (8) a to the outside of the hollow body.When the opening area of the gas discharge port is set to a smaller exhaust capacity than the exhaust capacity of the rotating body. Since the gas sucked into the hollow body (6)a is forcibly discharged to the outside, a kind of pressurizing effect is produced at the gas outlet, which generates compression heat and further reduces the exhaust temperature. It is Noh that raises the level. A similar action is performed on other hollow bodies. A part of the gas discharged from the hollow body is discharged into the box and then discharged to the outside from the KS Lux gas discharge port, 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.

Even if the exhaust side of the adjacent electric motor is controlled for 1 hour to take a smaller load lIt flow, heating and drying will be performed in the same way.

That is, in this embodiment, the adjacent tH motors II)a, IDb, 01)e that rotate each rotating body are controlled so that a smaller load current is taken on the exhaust side than on the intake side. As a control means, in adjacent electric intersperses, the capacity of the electric motor on the exhaust side is smaller than that on the intake side, or if the electric motors in contact with H have the same capacity, the capacity of the electric motor on the exhaust side is smaller than that on the intake side. In embodiments in which there is a means to reduce the supplied current, each electric motor (10a, IDb, fll

Open d. The total opening area of the gas discharge ports of each rotating ZETX is formed to be smaller than the gas discharge capacity of each hollow body.
Therefore, when dry matter such as plants, grains, animals, human bodies, granular materials, etc. is installed in the hollow body and each electric motor is driven, the air and other gases pass from the intake port (2) to the intake path (4). The gas in the hollow chamber (1) is mixed into the hollow body (6) a on the side of the air intake port.
Then, the gas flows through the gas inlet (7)a.

At this time, the opening area of the gas inlet (force a) is less than the gas suction capacity of the rotating body (1 (+1) a) installed in the corresponding hollow body (6) a, and the opening area of the gas inlet (7) a is Since the opening area of the exhaust port (8) a is limited to be smaller than the opening area of the rotating body θαa, the amount of gas inhaled is smaller than the gas discharged by the rotating body θαa. The pressure is reduced compared to other parts.

The entire hollow body is also depressurized. The pressure difference between the rotation region R and other parts, and the pressure difference between the hollow interior and the outside air are:
When the pressure difference gradually increases, a nearly equilibrium state is reached in relation to the gas flowing into the vicinity of the rotation region R.
Maintain this constant pressure state. 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 illa, the size of the opening area of the gas inlet (71A), the size of minute gaps, etc. However, this equilibrium and constant pressure state will be maintained as long as the rotating action of the rotating body tlola continues.In this equilibrium state, air stagnation occurs in the rotation region R of the rotating body nGa, and the rotating body 1
As the frictional action continues between the 1PL 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 then discharged from the gas outlet (
8) If the opening area of the gas exhaust port (8) a, which is discharged from a to the outside of the hollow body, is set to a smaller exhaust capacity than the exhaust capacity of the rotating body α1m, the gas sucked into the hollow body (6) a Since the gas is forcibly discharged to the outside, a part of the pressurizing effect is exerted at the gas outlet +8) a, and it is possible to further raise the exhaust temperature with the generation of compressed heat. 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 (6)a, (6)b is discharged to the boxes (9)a, (91b, and then to the gas discharge ports (t3a, (121b, +13c,
(It is discharged indoors from 121d, circulated indoors, heated and dried. Therefore, the exhaust side of each hollow body does not overheat, and the time to raise the temperature of hollow chamber +11 to, for example, about 60° C. is shortened.
