No. 161452, Patent Application No. 57-55089 or Patent Application No. 1982
- In No. 177508, etc., we proposed a series of methods and devices related to heat generation or heat generation based on the above-mentioned invention.

The invention of the above application includes a rotating body as a structure for depressurizing or pressurizing a hollow chamber or a cylindrical casing, a rotating region of the rotating body having a minute gap in which the rotating body is disposed, and a rotation area of the rotating body having a minute gap in which the rotating body is disposed. A frictional heat generating part is formed in the area, and the hollow chamber or the cylindrical casing is depressurized or pressurized by the rotation of the rotating body, and the pressure difference between the indoor and outdoor is kept in a constant constant pressure equilibrium state, and In this state, the frictional heat generating section promotes the frictional action to generate frictional heat, thereby drying or generating heat.

The present invention is based on the technical contents of the series of inventions described above, and an object of the present invention is to provide a novel rotary heating device that is even more efficient and can be used for various purposes.

Examples of the present invention will be described in detail below.
1 is a cylindrical casing 2 that constitutes a heat generating unit A.
It is a rotating body disposed inside and is composed of an electric motor 1a and a rotating blade 1b. 3 is rotating body 1
2 shows a frictional heat generating portion formed in the rotation region R of the rotating blade 1b, which can produce an effective frictional heat generating effect in the minute gap g formed between the rotating blade 1b and the cylindrical casing 2. Reference numeral 4 indicates a gas inlet opening on the rotating blade 1b side of the cylindrical casing 2, 5 indicates an opening of a hot air extraction mechanism B connected to this gas inlet 4, and a gas introduction pipe 6 is arranged at the center position. A circular passage 7 is formed on the outer periphery of the tube 6. 8 is a heat storage space formed on the outer periphery of this circular passage 7;
Although it is desirable to fill the inside with a heat storage material 9 (preferably a metal with a high heat storage effect such as aluminum or iron), this heat storage material 9 may be omitted. Reference numeral 10 denotes a warm air discharge section provided along the outer wall of the heat storage space 8, which is formed of a required number of tubes that can be opened and closed and whose air volume can be adjusted.

11 indicates a gas discharge port formed on the electric motor 1a side of the cylindrical casing 2 of the heating unit A;
In the figure, a valve 12 which can be opened and closed and whose opening degree can be adjusted freely is installed so that hot air can be taken out, but it may be closed as a blind structure.

Reference numeral 13 indicates a valve interposed in the gas introduction pipe 6, and its opening/closing and opening degree can be adjusted freely.

The rotating blades 1b of the rotary body have a desired number of biplane structures, a desired inclination angle, and a function of effectively sucking and discharging gas, so long as the blades have a desired number of blades, have a desired inclination angle, and can function to effectively suck and discharge gas. It is not limited to horsepower.

The action will be explained based on the above structure.

When the electric motor 1a is energized to operate the rotating body 1 and rotate the rotating blades 1b, outside air is sucked in from the open end of the gas introduction pipe 6 in the direction of the arrow by the suction action of the rotating blades 1b.

When the gas outlet 11 of the heating unit A is closed or the valve 12 is fully closed, the gas sucked into the electric motor 1a side of the cylindrical casing 2 by the rotary vane 1b cannot flow out. is retained in the cylindrical casing 2 in a pressurized state and subjected to compression action, generating compression heat, but maintains a constant pressure equilibrium state in a pressurized state corresponding to the suction and exhaust capacity of the rotating body 1. .

That is, the suction gas entering the rotation region R of the rotor 1 is forced to stagnate, and the rotor blade 1b
Frictional heat is generated under the rotational agitation action of the frictional heat generating section 3, and a rapid thermal action is generated in the frictional heat generating section 3.

However, due to the rotational action of the rotary blade 1b, the reduced pressure suction gas facing in front of the rotary blade 1b rotates vertically in the same direction as the rotary body 1 due to the viscous resistance of the gas, and the opening of the gas introduction pipe 6 There is a tendency to move from the inner end 6a toward the outer circumferential direction in the direction of the arrow.

This vertically rotating gas component retains the thermal energy generated in the frictional heat generating section 3 of the rotating body 1, enters the heat storage space 8 of the hot air extraction mechanism B via the annular passage 7, stores enough heat, and becomes warm. A necessary amount of hot air can be obtained from the air discharge section 10.

In addition, when adjusting the opening degree of the valve 12 of the heating unit A, the flow of the sucked gas varies depending on the suction and exhaust capacity of the rotating body 1, but any valve opening degree is Even in this case, the pressure of the gas in the heating unit A is reduced on the inflow side and increased on the outflow side, so that the desired constant pressure equilibrium is always achieved, and the frictional heat generating portion of the rotation area R of the rotating body 1 is maintained. 3 is maintained, heat generation is promoted and hot air can be discharged from the gas outlet 11 side rather than from the hot air discharge section 10.

In this case, if the opening degree of the valve 13 of the gas introduction pipe 6 is small or fully closed, the hot air discharge part 10 of the hot air extraction mechanism B
When the hot air discharge section 10 is open, outside air may be sucked in from the warm air discharge section 10.

Next, the embodiment shown in FIG. 2 shows a case where the rotary heat generating device according to the present invention is incorporated into a chamber 14 having a closed structure. This chamber 14 is not only used as a heating pot as a whole, but also has an opening/closing door (not shown) for allowing the material to be dried to enter and exit, in order to use the chamber 14 as a large-capacity structure for purposes such as drying. Alternatively, as shown in the figure, a hot air or an outlet pipe 15 for taking out hot air may be connected as a heat source so that a necessary amount of hot air can be taken out when necessary using a valve 16.

In either case, it is preferable that one end of the gas introduction pipe 6 of the hot air extraction mechanism B be communicated with the outside of the chamber 14 to introduce gas from outside the chamber 14.

The heat-generating action of the rotary heat-generating device within the chamber 14 is the same as in the previous embodiment and there is no difference, so a detailed explanation thereof will be omitted.

Although the two embodiments have been described above, this invention further includes a
―Other rotary plates shown in No. 21185 and JP-A-1988-
The swirling effect of the sucked gas can be increased by adding a vertical rotation mechanism as shown in No. 139271.

In addition, although the rotating body 1 of the heat generating unit A is shown as having one structure in each embodiment, there may be two rotating bodies 1,
Of course, if the required number of blades such as three can be provided in a row in the cylindrical casing 2, the rotary blades 1
A patent application filed in 1983 has a structure in which only the number of blades b is set to a desired number such as two or three, and these rotary blades 1b are installed on one rotating shaft provided on one electric motor 1a.
A rotating body with a multi-stage fan as shown in No. 55089 may also be used.

According to this invention, by the hot air extraction mechanism connected to the heating unit, gas drawn from the outside can be heated and discharged as hot air or hot air by a swirling action, and the hot air can be discharged as hot air. Since the extraction mechanism has a heat storage space, it has the advantage of being able to store sufficient thermal energy.

In addition, the heating unit forms a frictional heat generating part with a small gap in the rotating region of the rotating blades of the rotating body, so the gas accumulated in this part is subjected to the rotational friction stirring action of the rotating blades. Since it generates heat rapidly and effectively and can provide hot air or hot air at the required temperature, it can be used as a heat source for various purposes, not only for space heating and greenhouses, but also for all industrial purposes for drying or heating.
