Description

Centrifugal heat pump with toothed disk structure {CENTRIFUGAL HEAT PUMP HAVING SAWTOOTH STRUCTRUE DISK}

The present invention relates to a centrifugal heat pump having a serrated disk structure, and more particularly, to a centrifugal pump structure having a serrated disk structure which can improve water supply efficiency by crushing and colliding the supplied water efficiently to further activate water molecules. It relates to an exothermic pump.

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 the development of technology, while handling is simplified, but the structure is complicated, which requires a high level of technology in the process cost 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 order to solve this problem, various types of energy-saving boilers have been proposed.

However, these energy-saving boilers, like conventional boilers, have to face some limitations in saving energy in a way of heating water by burning fuel such as oil, gas, and coal.

In particular, in the reality that energy consumption resources are depleted and the total amount of energy is imported from abroad, the necessity of alternative energy means to solve such long-term high oil price burden is increasing.

In addition, security of energy resources, such as enactment of national energy conservation laws, is more important than ever due to the entry into force of the climate convention. Therefore, the development of the heating / hot water supply facilities through the use of non-fossil fuel is urgently required.

There is a centrifugal heat pump that does not use such fossil fuel, that is, to make a low-temperature fluid high temperature by using kinetic energy through axial rotational force without heat generation by combustion products.

The centrifugal heat pump rotates a disk at high speed through a shaft in a housing having a constant enclosed space, so that fluid molecules flowing along the inside of the housing collide with each other, so-called cavitation phenomenon (the flow is accelerated in the fluid and the pressure is low. When it occurs, the gas in the water is separated and bubbles are generated), which causes the low-temperature fluid to change into a high-temperature fluid.

However, the conventional centrifugal heat pump has a problem in that the disk structure is formed in a simple disc structure, and thus there is a problem in that the crushing (collision) performance of the water molecules is lowered, so that it is difficult to efficiently increase the hot water efficiency.

The present invention has been made to solve the above problems, to provide a centrifugal heat pump having a toothed disk structure that can improve the hot water efficiency by crushing and colliding the water supplied to further activate the water molecules. The purpose.

According to an embodiment of the present invention for achieving the above object, a motor having a rotating shaft; A housing in which the motor is mounted and in which an inflow path at an upper portion thereof and an outlet passage at a lower portion thereof are formed; A drive shaft coupled coaxially with the rotation shaft to be located inside the housing; A plurality of disks are arranged on the drive shaft at regular intervals, the disk is formed in the circumferential direction, a plurality of disks are formed in a groove of a predetermined depth, the bottom surface is formed in the axial groove is formed, the axial groove A centrifugal groove is formed in the form of a slit having a predetermined width in the centrifugal direction, and the teeth are continuously formed along the outer circumference of the disk, and the teeth are each formed with a wide upper portion and a narrower lower portion between the teeth. The space portion provides a centrifugal heat pump having a serrated disk structure in vertical communication with the centrifugal groove.

In the disk, the fluid is introduced into the axial groove and guided at right angles to the centrifugal groove so as to flow out of the space portion, and the fluid is preferably impinged on the inner wall of the housing.

The distance from the highest point of the teeth of the disk to the inner wall of the housing is 1 mm to 10 mm, and the distance from the lowest point of the teeth where the space is located to the inner wall of the housing is 15 mm to 50 mm.

The inside of the housing may further include a guide plate for guiding the fluid supplied and installed to be close to the disk of the uppermost to the axial groove.

It may further include a ring-type partition member mounted on one side of the disk to seal the side opening surface of the space formed between the teeth.

The interval from the highest point of the partition member to the inner wall of the housing is preferably 0.1mm to 0.5mm.

According to the present invention, the water supply efficiency can be improved by forming a tooth on the outer circumferential surface of the disk and causing water molecules to collide in the space between the teeth. By impinging and crushing the multi-stage fluid supplied through the centrifugal grooves communicated with each other, there is an effect of improving the collision performance of the water molecules to improve the device efficiency.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of a centrifugal heat pump having a serrated disk structure according to an embodiment of the present invention.

As shown in FIG. 1, the centrifugal heat pump of the present invention includes a motor 100, a fixed plate 130, a housing 210, a disk structure 251, and a drive shaft 250.

The motor 100 is installed so that the rotating shaft 110 is positioned below, the motor 100 is coupled to the fixing plate 130 and the rotating shaft 110 is penetrated through the fixing plate 130. The fixing plate 130 may be composed of a first plate 131 integrally formed on one side of the motor 100 and a second plate 132 screwed to the first plate 131. In addition, the second plate 132 may be equipped with a first bearing 120 to facilitate the rotational movement of the front end of the drive shaft 250 (action to reduce friction).

On the other hand, a plurality of support 230 is installed around the fixing plate 130 serves to support this when driving the motor 100 is installed in a standing state. In addition, the inside of the housing 210 is provided with a guide plate 240, the guide plate 240 is installed in close proximity to the inflow path 150 to supply the supply water supplied to the inflow path 150, the uppermost disk structure (251a) To the through hole (H1). In detail, the guide plate 240 is divided into a first plate 241 and a second plate 242, and the disk structure 251 in a state in which the supply water introduced into the housing 210 is not filled in the housing 210. The idle rotation occurs during the rotation of the shaft serves to guide the supply water to the flow path of the uppermost disk structure (251a) to prevent the smooth collision and guidance of the fluid.

 The drive shaft 250 is coaxially connected to the rotation shaft 120 of the motor 100. That is, a spline (or a key groove method) is formed on the rotation shaft 120 and a spline groove is formed on the driving shaft 250 to be directly connected on the coaxial line. In addition, since the tip is fixed through the first bearing 120 mounted on the fixing plate 130, power transmission can be easily performed without a separate coupling. Can be miniaturized.

The disk structure 251 has a structure in which a plurality of disc structures 251 are installed at predetermined intervals. The disk structure 251 is formed with an inlet groove (H3) and the induction hole (H2) vertically communicated in the inlet groove (H3). Accordingly, the fluid introduced into the disk structure 251 forms a flow path discharged to the guide hole (H2) through the inlet groove (H3). Accordingly, the induced fluid is finely pulverized (impacts with water molecules) in the first inlet groove H3, and is secondly pulverized in the induction hole H2 and collided with the inner surface of the housing 210 to be tertiarily pulverized. . In this process, water molecules collide with each other, resulting in a phase change in which the low temperature fluid becomes the high temperature fluid.

In this case, a closing plate 220 for sealing is installed at the end of the housing 210, and the finishing plate 220 may be formed through the outlet passage 160 through which the high temperature fluid is discharged. In addition, the inlet passage 150 is formed at the front end (fixing plate; 130) inside the housing 210 to receive the supply water, thereby causing water molecules to collide through the disk structure 251 inside the housing 210. It has a structure that discharges through the outlet passage 160 of the closing plate 220.

Hereinafter, the disk structure of the centrifugal heat pump of the present invention will be described in detail with reference to FIGS. 2 to 6.

Figure 2 is a plan view showing a disk of the sawtooth disk structure according to an embodiment of the present invention, Figure 3 is a partial detailed view showing a disk of the sawtooth disk structure according to an embodiment of the present invention, Figure 4 Partial perspective view showing a disk of a serrated disk structure according to an embodiment of the present invention, Figure 5 is a detailed view showing the shape of the axial groove and the centrifugal groove of the disk of the toothed disk structure according to an embodiment of the present invention 6 is a side cross-sectional view showing the relationship between the axial groove and the centrifugal groove of the disk of the toothed disk structure according to the embodiment of the present invention.

As shown in FIG. 2, the disk 30 of the present invention is formed such that the teeth 35 are continuous along the outer circumference, and a plurality of axial grooves 31 are formed on the front surface of the disk 30 along the circumferential direction. . In this case, the axial groove 31 refers to the axial direction of the drive shaft 250 on which the disk structure 251 is mounted (consistent with the flow direction of the fluid) in FIG. 1. Specifically, the axial groove 31 is formed in the form of a groove concave to the disk 30 by a predetermined depth in the form of the bottom surface (inside of the disk) as shown in FIG.

Further, the centrifugal groove 32 is formed in the direction perpendicular to the axial groove 31 (ie, the centrifugal direction when the disk is rotated). The centrifugal groove 32 may be formed in the form of a slit as shown in FIG. 4 and is formed between the teeth 35a and the teeth 35b. Specifically, the centrifugal groove 32 is formed on a surface between the teeth 35a and the teeth 35b at a predetermined portion (not formed as a whole but partially so as not to be completely penetrated in the axial direction).

On the other hand, the toothed portion 35 is formed with a predetermined volume of the space portion 33 between the toothed 35a and the toothed 35b. The space 33 is also formed in communication with the centrifugal groove 32. In other words, the open side of the centrifugal groove 32 is exposed to the space 33. More specifically, the tooth part 35 has a distance L1 (see FIG. 5) from the highest point of the tooth to the inner wall of the housing 10 and is 1 mm to 10 mm, and the distance from the lowest point of the tooth to the inner wall of the housing 10. (L2; see Fig. 5) is preferably 15mm ~ 50mm. That is, the highest point of the tooth serves as the disk and the partition wall at the time of rotation at an interval substantially in contact with the inner wall of the housing 10, while water molecules collide against the inner wall of the housing 10 between the teeth formed with the space portion 33 to be broken. It acts as an area to become.

In such a configuration, the fluid (constant) introduced into the inflow path 150 is introduced into the lateral groove 31 of the disk 30 to induce a primary collision. The fluid introduced into the lateral grooves 31 by the centrifugal force of the disk 30 is then led to the centrifugal grooves 32 and the secondary collision occurs in the centrifugal grooves 32.

Subsequently, the fluid discharged by the centrifugal force from the centrifugal groove 32 strikes the inner wall of the housing 10 to cause the third collision. At this time, as the disk 30 continuously rotates, water molecules in the space 33 formed between the teeth collide again and have a process of flowing into the centrifugal groove 32 of the next disk according to the fluid flow. Such a series of processes occur continuously according to the number of individuals of the disk 30, and in this process, water molecules are further activated, thereby making efficient hot water supply.

That is, when the disk 30 rotates, the fluid flows into the axial groove 31 and is guided at right angles to the centrifugal groove 32 so that the fluid flows out into the space 33. To collide with the inner wall.

At this time, the space portion 33 has a wide upper portion (outermost in the diameter direction) and a narrower lower portion to form a fluid flow in a predetermined direction (fluid flow from the inlet to the outlet of the housing) during the rotation of the disk 30. do. Accordingly, while ensuring a smooth flow of oil, it serves to improve the collision performance of water molecules.

7 is a plan view showing the disk structure of the centrifugal heat pump having a sawtooth disk structure according to another embodiment of the present invention, Figure 8 is a disk of the centrifugal heat pump having a sawtooth disk structure according to another embodiment of the present invention Side cross-sectional view of the structure.

As shown in FIGS. 7 and 8, as another embodiment of the present invention, a ring type is mounted on one side of the disk 30 to seal the side opening surface of the space portion 33 formed between the teeth 35. The partition member 40 is provided. At this time, the distance (L3) from the highest point of the partition member 40 to the inner wall of the housing is preferably 0.1mm ~ 0.5mm.

Accordingly, the fluid introduced along the axial groove 31 of the disk 30 flows into the centrifugal groove 32 and is discharged into the space 33, and once again collides with the partition member 40 between the housing and the partition member. It can be moved to the next disk along the gap L3.

That is, the partition member 40 serves to once again pass the fluid from the preceding disk to the immediately adjacent disk. In other words, the water molecules of the fluid introduced into the axial groove 31 during the rotation of the disk 30 cause a first collision and are moved to the centrifugal groove 32 by centrifugal force, and the space portion 33 between the teeth 35 is rotated. In order to cause the secondary collision, the partition member 40 may be installed to fill the space 33 to prevent the fluid from moving to the adjacent disk in accordance with the flow of the fluid.

As a result, the fluid introduced into the space 33 may hit the partition member 40 and move to the adjacent disk through the space between the inner wall of the housing 10. Through the disk 30 structure (the partition member; the reinforcement structure of 40), the fluid flow can be further extended, thereby increasing the collision performance and the coagulation / crushing performance of the water molecules.
