It is preferable that a guide member 190 is provided to impart orientation to the heat medium oil supplied by 180. The impeller 180 is fixed to the inner circumferential surfaces of the hollow parts of the first and second rotation shafts 120 and 130, and rotates together with the first and second rotation shafts 120 and 130, and then through the fluid inlet holes 121 and 131. The pressure at the center of the first and second rotary fans 140 and 150 is a function of feeding the heat medium oil flowing into the second rotary shafts 120 and 130 toward the center of the first and second rotary fans 140 and 150. This increases the ability to heat the heat medium oil. The impeller 180 may have a form similar to a conventional axial fan, or may have a screw shape in which one or a plurality of wings are spirally wound along an axial direction.

In addition, the guide member 190 imparts a straightness to the heat medium oil flowing into the center of the first and second rotary fans 140 and 150 by the impeller 180, thereby providing a central portion of the first and second rotary fans 140 and 150. It will act to further increase the pressure (P1) at.

Here, the guide member 190 is formed in a circular ring shape rim (191) (rim) fixed to the inner circumferential surface of the first and second rotary shafts (120, 130), and formed radially inside the rim (191) It may be composed of a plurality of guide wings 192 to guide the flow of the heat medium oil.

Referring back to FIG. 2, the first rotating fan 140 has a disc-shaped base 141 having a central portion fixed to the first rotating shaft 120 and spaced apart from the base 141 at regular intervals along a radial direction. It is arranged so that the plurality of orifice holes 143 through which the heat medium oil passes through is formed of a plurality of cylindrical blades 142.

In addition, the second rotary fan 150 is a disk-shaped base 151, the center of which is fixed to the second rotation shaft 130, and the base 151 is spaced apart at regular intervals along the radial direction and the heat medium oil is A plurality of orifice holes 153 passing through are formed to be formed through a plurality of cylindrical blades 152 disposed between the blades 142 of the first rotating fan 140.

As described above, the first rotating fan 140 and the second rotating fan 150 have a structure in which blades 142 and 152 having a plurality of orifice holes 143 and 153 are alternately disposed along the radial direction.

The first and second driving units are wound on the first and second driving motors 161 and 163, the shafts of the first and second driving motors 161 and 163, and the first and second rotating shafts 120 and 130, respectively. The first and second power transmission belts 162 and 164 transmit power of the second driving motors 161 and 163 to the first and second rotation shafts 120 and 130. The first and second driving units simultaneously rotate the first and second rotation shafts 120 and 130 in opposite directions.

Meanwhile, referring to FIGS. 4 and 5, the orifice holes 143 formed in the blade 142 of the first rotating fan 140 are formed to be inclined in a direction opposite to the rotation direction of the first rotating fan 140. It is preferable that the inner portion is formed in a cone shape in which the cross-sectional area increases from the outer portion. In addition, the central axes of the orifice hole 143 is preferably located eccentrically a certain distance from the rotation center of the first rotary fan 140.

In addition, the plurality of orifice holes 153 formed in the blade 152 of the second rotating fan 150 may also be formed to be inclined in a direction opposite to the rotation direction of the second rotating fan 150. That is, the orifice holes 143 of the first rotating fan 140 and the orifice holes 153 of the second rotating fan 150 are preferably inclined in opposite directions. As such, the orifice holes 143 of the first rotating fan 140 and the orifice holes 153 of the second rotating fan 150 are formed to be inclined in opposite directions to each other so that the heat medium passes through the orifice holes 143 and 153.

The orifice holes 143 and 153 are preferably formed in such a manner that the cross-sectional area increases from the inner side to the outer side.

Referring back to FIG. 2, a discharge port 201 for discharging the heat medium oil, which is heat-exchanged to a low temperature state, is installed at a lower part of the fluid tank 200 of the heating maintenance device, and a boiler (above) is provided at the upper part of the fluid tank 200. An inflow port 202 through which the high temperature heat medium oil supplied from 100 is introduced is installed. The discharge port 201 is connected to the supply pump 400. In addition, the inlet port 202 is connected to the outlet 113 of the boiler 100 through the fluid discharge pipe 910.

The fluid tank 200 is provided with a pressure gauge 210 for measuring the pressure in the fluid tank 200, and a temperature sensor 220 for measuring the temperature inside the fluid tank 200.

The first pressure side 710 and the second pressure side 720 are respectively installed in one side of the heating chamber C2 and the inlet port 202 of the boiler 100, and the flow of fluid in only one direction Permissible one-way valve.

The auxiliary fluid tank 600 has one side connected to the first and second pressure sides 710 and 720, and the other side connected to the fluid tank 200, so that the boiler 100 or the fluid tank 200 When the pressure reaches a predetermined pressure or more and the gas and the heat medium oil are discharged through the first and second pressure sides 710 and 720, the discharged gas and the heat medium oil are supplied, and the supplied heat medium oil is again supplied to the fluid tank 200. Supplying it inside prevents the phenomenon that heat medium oil runs out.

The heat exchanger 300 may be formed in the form of a coil in which a pipe in which the heating fluid circulated by the heating circulation pump 510 flows spirally in the fluid tank 200.

The heating heat storage tank 500 is composed of a large-capacity tank capable of storing a large amount of heating fluid (water in this embodiment), it is possible to send a lot of heating fluid to the place where heating is needed.

The boiler 100 and the heating maintaining apparatus of the present invention configured as described above operate as follows.

The heat medium oil is supplied from the fluid tank 200 to the boiler 100 by the supply pump 400, and the supplied heat medium oil is inflow chambers at both sides through the first and second inlets 111 and 112 of the boiler housing 110. Flows into (C1).

In this state, when power is applied to the first and second driving motors 161 and 163 from a controller (not shown) controlling the first and second driving units, the first and second driving motors 161 and 163 operate. The first and second rotation shafts 120 and 130 rotate at high speeds in opposite directions. At this time, the impeller 180 inside the first and second rotary shafts 120 and 130 is also rotated together, and the heat medium oil filled in the inflow chamber C1 is the fluid inlet hole 121 of the first and second rotary shafts 120 and 130. , 131 flows into the hollow portion of the first and second rotary shafts 120 and 130, and then is forcibly pushed by the impeller 180 to be formed through the inner ends of the first and second rotary shafts 120 and 130. It is discharged to the center of the first and second rotating fans (140, 150). In this process, the heat medium oil flowing into the first and second rotary fans 140 and 150 by the impeller 180 is guided by the guide blade 192 of the guide member 190 to flow while being provided with straightness. By the action of the impeller 180 and the guide member 190, the pressure at the center of the first and second rotating fans 140 and 150 is further increased.

Meanwhile, as described above, when the first and second rotating fans 140 and 150 rotate in opposite directions at high speeds, the rotation speed between the innermost blades 142 and 152 and the outermost blades 142 and 152 is increased. Due to this difference, a sudden pressure difference occurs. That is, the pressure outside the first rotary fan 140 rapidly decreases to form a vacuum, whereby the heat medium oil in the center of the orifice holes 143 and 153 and the second rotation of the first rotary fan 140 are rotated. The temperature is increased by receiving the expansion pressure while flowing outward through the orifice holes 143 and 153 of the fan 150.

4 and 5, when the first and second rotating fans 140 and 150 rotate at high speeds in opposite directions, the first and second rotating fans may be as shown in Equation 1 below. A difference occurs in the rotational angular velocity between the inner blades 142 and 152 of the 140 and 150 and the outer blades 142 and 152 of the first and second rotating fans 140 and 150.

Where ω = 2π × n.

And the velocity (V ₁ , V ₂ ) that the heat medium oil comes out as shown in Equation 2 below,

.

For example, the rotation speed of the second rotary fan 150 is 3500 rpm, the radius r ₁ of the innermost blades 142 and 152 is 150 mm, and the radius r ₂ of the blades 142 and 152 outside thereof. ) Is 300 mm,

V ₁ = V _k1 × cosθ ₁ = 2 × π × 0.15 × 3500

V ₂ = V _k2 × cosθ ₂ = 2 × π × 0.30 × 3500

V ₂ = 2 × V ₁

Therefore, the speed V ₁ through which the heat medium oil escapes through the inner blades 142 and 152 and the speed V ₂ through which the heat medium oil escapes through the outer blades 142 and 152 are twice as different, and the inner blade ( The pressure P2 at the outer blades 142, 152 is significantly lower than the pressure P1 at the portions 142, 152.

5, the orifice holes 143 and 153 of the first and second rotary fans 140 and 150 are formed obliquely in opposite directions with respect to the rotational direction, so that the heat medium oil toward the outside is formed. Cut and friction by the first and second rotating fans 140 and 150 rotating at high speed while continuously passing through the orifice holes 143 and 153, and thus mechanical energy is converted into thermal energy and thus The effect of a faster temperature rise can be obtained. In addition, since the orifice holes 143 and 153 are wider than the inner part, the orifice holes 143 and 153 may increase the expansion pressure of the heat medium oil discharged through the orifice holes 143 and 153 to increase the temperature more rapidly. This action is further doubled by the first rotary fan 140 and the second rotary fan 150 to rotate in the opposite direction.

As described above, in the boiler 100 of the present invention, the first and second rotary fans 140 and 150 rotate at high speeds in opposite directions to generate rapid pressure differences between the inner and outer parts, respectively. The mechanical oil is converted into thermal energy while cutting and rubbing the thermal oil toward the outside through the first and second rotating fans 140 and 150 rotating at a high speed, thereby rapidly increasing the temperature of the thermal oil flowing to the outside. You get an effect.

In addition, since the inner space of the boiler housing 110 is separated into the inlet chamber C1 on both sides and the heating chamber C2 in the center by the first and second compartment plates 115 and 116, the volume of the boiler housing 110 is reduced. It can increase, and thus can significantly increase the amount of heat medium oil that can be heated in the boiler 100 than the conventional can provide excellent performance.

The heat medium oil heated by the boiler 100 may be up to 300 ° C. to 400 ° C., depending on the type of heat medium oil.

The heating medium oil heated to a high temperature by rotating in the opposite directions of the first and second rotary fans 140 and 150 in the heating chamber C2 of the boiler 100 is discharged through the discharge port 113 and then the fluid discharge pipe Flow along the 910 is supplied into the fluid tank 200 through the inlet port 202 of the fluid tank 200.

By the action of the boiler 100, the inside of the fluid tank 200 is filled with a high temperature heat medium oil to increase the temperature and pressure.

At this time, the heating fluid (water in this embodiment) by the heating circulation pump 510 flows through the heat exchanger (300). The water passing through the heat exchanger 300 is heat-exchanged with the heat medium oil in the fluid tank 200, the temperature is raised, then stored in the heat storage tank 500 for heating and sent to a place requiring heating to perform the heating It is returned to the heat exchanger 300 again.

Meanwhile, as described above, the heating medium oil is heated in the boiler 100 to be supplied to the fluid tank 200, and the heating fluid is heated by the heat exchanger 300 in the fluid tank 200 to perform heating. Temperature and pressure inside the 100 and the fluid tank 200 are gradually increased. When the pressure inside the boiler 100 or the fluid tank 200 is higher than the designed pressure, there is a risk of damage or damage to the boiler housing 110 or the fluid tank 200, or a malfunction.

Therefore, when the pressure inside the boiler 100 or the fluid tank 200 reaches a predetermined pressure or more, the first pressure valve 710 or the second pressure valve 720 is opened while the gas and the heat medium oil are discharged to support the auxiliary fluid tank. Supplied to 600. The heat medium oil supplied to the auxiliary fluid tank 600 is supplied into the fluid tank 200 to replenish the heat medium oil lost from the fluid tank 200.

The embodiment of the above-described heating maintenance device heats the heating fluid (water) through heat exchange in the fluid tank 200 without performing heating by sending the heat medium oil heated in the boiler 100 to a place for direct heating, and By sending the heated heating fluid to a place requiring heating, a large area of heating can be heated using a large amount of heating fluid.

However, otherwise, if you want to heat a small area, the heating medium oil heated in the boiler 100 may be sent directly to a heating place to heat and then circulated inside the boiler 100.
