In general, a boiler is widely used as a supply device for heating or hot water. These boilers heat water for a period of time and supply it to the water supply or heating facility through piping. Here, as a means for heating the water, it is common to provide a separate combustion chamber to heat the water.

In recent years, boilers have improved performance due to advances in technology, and handling has been simplified. However, complicated boilers have a disadvantage of requiring advanced technology in terms of construction costs and maintenance. In addition, the burden on the supply and demand of fuel according to the cost and high costs associated with boiler handling is increasing.

In particular, in recent years, electric boilers have been developed to reduce fuel prices for high oil prices at low electricity rates through midnight electricity.However, even low-priced electricity rates have been changed at high prices due to the increase in power consumption due to cold weather, making it difficult to use electric boilers. There was this.

In order to solve this problem, various types of energy saving boilers for reducing fuel loss have been proposed.

As an example of an energy saving boiler, a centrifugal heating pump has been developed that allows a low temperature fluid to be made high by using kinetic energy in which a disk rotates without heat generated by a combustion product (fossil fuel or electricity).

The present invention has been proposed to improve the above problems in the prior art, by providing a backflow prevention structure for preventing the warm water warmed up from flowing back to the central axis upper bearing side problems caused by the corrosion of the bearing It is intended to be solved.

The centrifugal heat pump of the present invention for achieving the above object, the inlet for the water is introduced, the outlet for discharging the hot water heated therein is formed, respectively, the main body housing is configured to be inserted into the drive center axis; A drive motor connected to one side of the main body housing to transmit power to the drive central shaft; A plurality of heating disks coupled to the driving central shaft at regular intervals and having friction grooves formed along an outer edge thereof; A flange cover body coupled to one side of the main body housing to support one end of the driving central shaft; A central shaft upper support bearing for rotatably supporting a driving central shaft in the flange cover body; One side of the drive central shaft is formed to form a water flow in the radial direction of the shaft to form a configuration comprising a water flow groove for preventing the water in the body housing to flow into the central shaft upper bearing side.

The centrifugal heat pump of the present invention prevents backflow by forming a water flow that blocks water from flowing into the upper bearing side of the central shaft supporting the driving central shaft in the process of pumping, thereby preventing a backflow phenomenon and causing a failure of the device such as bearing corrosion.

In particular, as shown in FIGS. 4 and 5, the upper portion of the driving central shaft 20 of the present invention forms water flow in the radial direction of the shaft so that the water in the main housing 10 moves upward and flows into the upper bearing 60 side of the central shaft. A water flow groove 21 for blocking the water is formed, and the flange cover body 50 is provided with an auxiliary water outlet 52 through which air is introduced from the outside when the water flow is generated while discharging the water moved upward.

In addition, it is preferable that a water flow guide groove 51 is formed on an inner wall surface of the flange cover body 50 corresponding to the water flow groove 21 so as to secure a space in which the water flow by the water flow groove 21 can be formed. .

On the other hand, a lower support ball 70 for supporting the rotation of the drive center axis 20 is configured at the lower end of the drive center axis 20, the lower support ball 70 is excellent in wear resistance And it is preferable that a cemented carbide material having excellent thermal conductivity is used, and the ball support 15 is formed in the center of the bottom surface of the main body housing 10 so that the lower support ball 70 can be seated.

The ball pedestal 15 is also preferably formed of cemented carbide material.

In addition, a lower portion of the driving central shaft 20 is provided with a central shaft lower bearing 16 for holding the center of rotation of the driving central shaft 20.

In addition, the ball pedestal 15 is configured to be fixed to the ball pedestal housing 17, the ball pedestal height adjustment bolt 18 for adjusting the height of the ball pedestal housing 17 is fastened to the lower ball pedestal housing 17 When the ball support 15 is worn by friction with the lower support ball 70, the ball support housing 17 is gradually raised by turning the ball support height adjusting bolt 18 to increase the height of the ball support 15 little by little. By giving it semi-permanent use.

Reference numeral 13 indicates a waste outlet.

In addition, an upper portion of the main body housing 10 is provided with an inlet 11 through which water is introduced from the outside, and a lower portion is provided with an outlet 12 for discharging hot water heated inside.

The heating disc 40 has a plurality of through-holes 42 are formed so that the water can be distributed, a plurality of friction grooves 41 so that friction heat with the water particles due to the high-speed rotation along the outer edge can be generated It can be seen through Figure 7 that the formed at regular intervals.

Meanwhile, the centrifugal force disk 80 having a predetermined thickness is coupled to the driving central shaft 20 in a symmetrical form at the top and the bottom thereof so as to increase the rotational centrifugal force. The distribution hole 81 is formed.

In particular, as shown in FIG. 8, the centrifugal force disk 80 is preferably formed of a steel centrifugal force body 82 along the circumference of the disc so that a stronger centrifugal force can be applied.

In the figure, reference numeral 53 is a sealing agent for auxiliary blocking of water inflow into the central axis upper bearing 60, and 54 represents a coupling.

The effect of the operation of the vertical centrifugal heat pump of the present invention constituting such a configuration will be described.

First, when the driving motor 30 is driven while water is introduced into the main body housing 10 through the inlet 11, the driving center shaft 20 that receives the rotational force is rotated at a high speed while the inside is driven. The water filled in will generate heat.

That is, at this time, the friction grooves 41 formed in the plurality of heating disks 40 that are rotated at a high speed collide with the water molecules, thereby generating heat, and as a result, the low temperature water is gradually heated, thereby changing to hot water. You lose.

In particular, the centrifugal force disk 80 having a predetermined thickness is coupled to the upper and lower portions of the drive central shaft 20. The centrifugal force weight body 82 made of steel is formed along the periphery of the centrifugal force disk 80. By maximizing the centrifugal effect it is possible to increase the amount of heat generated while the heating disk 40 is rotated at a higher speed.

On the other hand, during the rotation of the driving center shaft 20, the lower support ball 70 of the cemented carbide material formed in the lower end of the shaft is heated while the friction with the ball support 15 is generated to heat the water to a higher temperature In addition, it is possible to shorten the heating time, which is an advantage of improving the energy efficiency.

That is, the center axis lower bearing 16 and the drive center axis which perform a function of holding only the center deviation of the drive center axis 20 by the rotation support means at the bottom with the state in which the drive center axis 20 is vertically established. By configuring the lower support ball 70 of the cemented carbide material to support the load of the 20, the heat is generated during the rotation process, the heat operation by the lower support ball 70 is generated by the heating disc 40 Combined with the heating operation will have the effect of further increasing the temperature of the hot water.

In particular, since the lower support ball 70 is rotated in the water it can exhibit the advantage of minimizing the temperature rise and utilizing the heat of friction in hot water heat generation.

Then, the hot water heated by the internal heating drive is supplied to the place of use through the outlet 12 of the lower portion.

On the other hand, in the heat pump operation process, the water is raised to the flange cover body 50 side along the drive central axis 20 by the internal pressure of the main body housing 10, this rise is the drive center shaft 20 By being blocked by the force of the water flow generated by the water flow groove 21 in the water can be prevented from entering the central shaft upper bearing (60).

That is, as the driving center shaft 20 is rotated at a high speed, water flow is formed in a radial direction around the water by the water flow groove 21 formed on the upper sidewall surface, thereby preventing the rise of water.

In particular, since the water flow guide groove 51 is formed inside the flange cover body 50 facing the water flow groove 21, it can be seen that the space for generating the water flow can be secured to generate a stronger water flow force. have.

At this time, by the inflow of the external air through the auxiliary outlet port 52 by the generated water flow force can further maximize the effect of preventing the rise of water.

In addition, when the inflow of water through the water inlet 11 is continuously performed while the driving of the driving central shaft 20 is stopped, water flow does not occur, so that the synergy of water may be achieved. The silver is prevented from rising by the sealant 53 and can be naturally discharged through the auxiliary outlet port 52, thereby preventing the central shaft upper bearing 60 from contacting with water.

Therefore, the centrifugal heat pump of the present invention can prevent the water flow back by the internal pressure generated during the driving of the pump flows into the upper bearing side of the central axis through the configuration of the water flow generated by the water flow groove and the configuration of the auxiliary outlet port. Therefore, it can be seen that the failure of the product can be prevented.

In addition, although specific embodiments of the present invention have been described and illustrated above, it is obvious that the centrifugal heat pump structure of the present invention may be variously modified and implemented by those skilled in the art.

However, such modified embodiments should not be understood individually from the spirit or scope of the present invention, such modified embodiments will be included within the claims of the present invention.
