Description

Centrifugal separation mist spraying device {Mist spray machine}

The present invention is a technical idea related to a mist spraying device capable of temporarily lowering the surrounding temperature while the water sprayed in the form of mist vaporizes, and more specifically, a water supply structure, a mist generating structure, a mist spraying structure, etc. By actively improving the overall structure of the injection device to the structure of the centrifugal separation method, various problems were accompanied by noise caused by the operation of the high-pressure piston pump to transfer water and dust clogging in the fine nozzle hole installed to spray high-pressure water. It is a centrifugal separation type mist spraying device that actively reduces operating costs through a series of operations such as water supply, mist generation, and mist spraying by simply operating a single motor and operating a single motor. .

In general, refrigerators and air conditioners have been developed using the principle that the surrounding temperature temporarily decreases as water vaporizes. In recent years, as environmental pollution becomes severe, the temperature of the atmosphere gradually increases to reduce this temperature. A device called a pole (mist spraying device) was developed.

The mist spraying device has a structure in which a pole is installed on the ground to receive water from a water supply pipe, and water is sprayed in the form of a mist from a plurality of fine nozzles installed at the top of the pole.

The mist spraying device is a high-pressure piston pump that divides the branch pipe from the water supply pipe and transfers water through a filtration filter, and creates a water pressure of about 70 bar so that the transferred water can be sprayed through a discharge port of about 0.1 to 0.2 mm of the nozzle. Is provided separately.

The high-pressure piston pump has a problem in that it consumes a lot of power and has a severe operating noise, but it has to endure very inconvenient conditions to be used as a driving means of a mist spraying device installed in a city park or street.

For example, as an example of the technology examples of the mist spraying device, Korean Patent Publication No. 1-2017-0098706 "Cooling mist spraying system" is published, and the technology is installed on the upper side of a structure and water is transferred to the structure in the form of cooling mist. It consists of a cooling mist nozzle that sprays around, and a pump that is installed on one side of the structure and connected to the cooling mist nozzle through a pipe, and supplies the water stored in the water tank to the cooling mist nozzle through the pipe.

As in the above case, the mist spraying device must have a pump for supplying water from the tap water or a separate water tank to the nozzle, as well as the spray nozzle composed of a discharge port of about 0.1 to 0.2 mm due to the fine discharge port. Frequent clogging occurred.

The present invention is a technical idea related to a mist spraying device capable of temporarily lowering the surrounding temperature while vaporizing water sprayed in the form of a mist.

Above all, the present invention actively improves the overall structure of the mist spraying device, such as the water supply structure, the mist generating structure, and the mist spraying structure, to a structure of a centrifugal separation method, thereby reducing noise and high pressure due to the operation of a high pressure piston pump for transporting water.

Fix it. The standing stand 100 is preferably configured to have a length of about 3 to 4m that does not touch a person's head, and although not shown in the drawing, it is preferable to configure the height to be adjusted according to the surrounding environment using an antenna method. .

The stand 100 is a power cable for driving a water discharge pipe (not shown) or a motor 400 for draining water exceeding the water level other than the water supply line 110 using a cable clip, or for operating an LED lamp It serves as a guide for the installation of the back.

2 to 3 are perspective views of a mist body configured according to a preferred embodiment of the present invention and an exploded perspective view showing a coupling relationship between the bodies.

As shown in Figure 2, the body 200 is provided with a water tank 210 for desalting water therein, and the water tank 210 is connected to the water supply line 110 to receive water to receive the cover body 300. ) And the motor 400 to provide a space for generating mist by the interaction.

In the water supply line 110, a floating valve 111 is further installed at an end from which water is discharged, and the water supply amount is automatically controlled as the water depth in the tank is detected in real time by a buoy provided in the floating valve 111.

On the other hand, the water supply line 110 is configured to be selectively shut off or discharged in each winter season due to a rapid decrease in temperature by installing a drain valve (not shown) at another end thereof.

As shown in FIG. 3, the body 200 includes a water tank 210 for desalting supplied water; and a water injection pump 220 for sucking water rotating by a motor 400 at one side of the water tank; Wow, a fluid transfer pipe 230 extending from the water injection pump to the coupling area between the cover body 300 and the motor 400 to transport the sucked water; and, installed at the end of the fluid transfer pipe and transported by valve operation It consists of; flow control valve 240 for controlling the discharge amount of water.

The body 200 having the above-described coupling structure first stores water provided by the water supply line 110 in the water tank 210 by a set water level. At this time, when the user drives the motor 400, the shaft of the motor and the cover body 300 coupled with the motor rotate at high speed to form a vortex in the freshwater water in the water tank. Water is pushed to the edge of the water tank by the centrifugal force of the vortex, and at this time, water is gradually sucked into the water spray pump 220 installed on one side of the water tank, and the cover body 300 and the motor 400 are combined through the fluid transfer pipe 230 It is discharged to the area.

The water discharged from the fluid transfer pipe 230 is discharged in drop units by the flow control valve 240, and the discharged water droplets are centrifuged by a rotating wind force generated by the cover body 300 and the motor 400 rotating at high speed. .

Meanwhile, the water tank 210 includes a plurality of protrusions 211 arranged at a set interval along the circumference at the top. The protrusion 211 serves to induce uniform discharge of the generated mist by centrifuging the water discharged from the flow control valve 240 by the rotational force of the cover body 300 and the motor 400.

In detail, the mist formed by centrifugation is scattered in all directions by the rotating cover body 300 or is moved to the edge of the body 200 due to centrifugal force, at this time, the protrusion 211 formed along the circumference of the water tank 210 ), it is discharged with repetitive gas oil into each interspace, inducing a natural expression such as fog, and uniform spraying.

The cover body 300 is disposed on the upper end of the body 200 and shields the inside of the water tank 210 to prevent various foreign substances from penetrating into the water tank so that a clean mist can be generated at all times, and the cover body ( 300) combines with the shaft of the motor 400 and simultaneously rotates by driving the motor, thereby simultaneously performing various roles such as generating eddy currents, inducing water supply, and generating mist in the freshwater water in the tank.

The cover body 300 performing the above role is made of a diameter corresponding to the inner diameter of the tank so as to shield the front surface of the tank 210, and the center has a shape of a disc that is convex upward to promote vortex generation. At the same time, it prevents water from splashing due to eddy currents, and furthermore, rotational wind power generated by rotation of the cover body 300 and the motor 400 is collected on the center line, thereby providing a space for improving centrifugal separation.

The motor 400 is fixedly installed on any one side of the bottom surface of the body 200, and the shaft of the motor penetrates the bottom surface of the body and is exposed to the inner space of the water tank, so that the cover body 300 and the screw seated on the top of the body It is concluded.

The motor 400 uses a motor capable of high-speed rotation, and preferably adjusts the spray direction of the mist according to the situation by using a bidirectional DC motor having a free rotation direction.

The motor 400 is connected to a power cable extending from the stand 100 to receive power and operates, and as described above, a vortex is generated in the water tank 210 by rotating the cover body 300 in one direction at high speed. , With the principle of capillary tube by vortex, it is the cornerstone of the power to collectively perform the roles of supplying water from the water supply line 110, inhaling water to the water injection pump, and converting the water droplets discharged through the flow control valve into mist. do.

4 is a diagram showing an internal assembly state of a body constructed according to a preferred embodiment of the present invention.

As shown in FIG. 4, the mist spraying device of the present invention receives water through the water supply line 110 buried in the ground, converts it into mist, and discharges it to a set area. The method of pulling up the water buried in the ground is to generate a vortex in the water stored in the water tank 210 as the motor 400 is driven and the cover body 300 rotates, and a vacuum state is formed in the center of the vortex to the water supply line. This is the principle that water is pulled up by generating suction.

The water supplied through the water supply line 110 starts to gradually fill the water tank 210 of the body 200, and when the water exceeds the appropriate water level of the water tank, a buoy of the floating valve 111 installed at the end of the water supply line The water supply is stopped as the valve is automatically shut off by.

On the other hand, the water in the tank is pushed to the edge by the rotation of the cover body 300. At this time, water continuously enters the water spray pump 220 installed on one side of the tank, and into a tube having a smaller diameter than the water spray pump. The water transferred to the formed fluid transfer tube 230 through the principle of a capillary tube is discharged to the coupling area between the cover body 300 and the motor 400.

The fluid transfer pipe 230 is further provided with a flow control valve 240 at an end thereof, and the amount of mist generated is controlled by controlling the discharge amount of water by operating the flow control valve.

The generated mist is again scattered in all directions by rotational wind power generated while the cover body 300 rotates at high speed, or moves to the edge of the body 200 by centrifugal force, and finally through the gap between the water tank 210 and the cover body. It is discharged to the outside.

At this time, the mist is uniformly discharged through repetitive passages into the space between the protrusions 211 arranged at a set interval along the circumference of the water tank 210, and is discharged by being separated by the intervals of the protrusions, thereby creating a natural expression such as fog. To induce.

On the other hand, between the mounting surface of the standing stand 100 and the body 200, a safety cover body 500 that is made of an enlarged diameter compared to the body to prevent dropping of water droplets due to condensation; is further installed.

A plurality of LED lamps 510 are further installed along the periphery of the safety cover body 500 to reflect LED lights to the spraying mist to give colors, thereby performing various directions as well as a street lamp.

On the other hand, the mist spraying device of the present invention provides a mist with sterilization and fine dust removal functions by generating a mist by attaching it to water after generating complex oxidized water.

To this end, the present invention adopts a structure capable of generating complex oxidized water by electrolyzing an aqueous solution containing a small amount of diluted hydrochloric acid (HCl) and other electrolytes (KCl, NaCl, etc.) and generating microbubbles in the body 200. Thus, while mixing water and complex oxidized water, the molecular structure of water and complex oxidized water can be pulverized and converted into microparticle size.

The present invention further includes a chemical tank 600 for generating complex oxidized water, and a small amount of dilute hydrochloric acid (HCl) and other electrolytes (KCl, NaCl, etc.) are freshly watered in the chemical tank. In addition, by supplying a DC voltage and current to the chemical tank 600, hydrogen (H₂) is generated at the cathode and gases such as chlorine (Cl₂) and oxygen (0₂) are generated at the anode due to the catalytic reaction of the electrode. These gases are partially dissolved or mixed in water. At this time, since the hydrogen ion concentration (pH) decreases during the electrolysis process, the pH of the electrolyzed electrolyzed water rises, and the pH of the complex oxidized water produced by mixing with the raw water finally has a weak acidity between 5.5 and 6.5. .

The complex oxidized water obtained by the catalytic reaction of the electrode as described above is introduced into the body 200 connected to the chemical tank 600, and mixed with water while a eddy current is generated by the rotational wind power of the cover body 300 and the motor 400. .

At this time, the body 200 has a spiral wing 250 further formed along the inner wall of the tank 210 so that the water of the tank and the complex oxidized water continuously rotate along the wing, generating a more powerful eddy current and elaborately mixed.

The body 200 is further provided with a gas discharge pipe 260 for injecting air supplied from the outside into the water tank within a range in which the motor 400 does not interfere with the center line of the water tank 210, and is combined with rotating water. By continuously injecting air into the oxidized water, it causes a cavitation to form microbubbles.

Since the microbubbles have excellent cleaning ability, they clean the inside of the body 200 by themselves while rotating in the water tank 210, and clean the surrounding environment by decomposing bacteria and fine dust in the surrounding air with appropriate oxidizing power. To improve.

The mist spraying device of the present invention having the above configuration deviates from the conventional method of incurring facility and maintenance costs due to frequent damage by embedding a high-pressure fluid transfer pipe in the ground to transfer high-pressure fluid. Since the capillary phenomenon occurs due to the eddy current action by rotation and the water from the tap water is supplied by the suction force of the capillary phenomenon, water can be supplied without burying a separate high-pressure fluid pipe, and construction and management are easy with a simple structure.

In addition, the high-pressure piston pump required to supply water or spray the water to the nozzle replaces water supply and mist injection by vortexing and centrifugal separation by rotation of the motor and cover body. It is possible to actively reduce the facility management cost or maintenance cost for power consumption to operate.

In addition, without a nozzle that generates and sprays mist, mist is generated by centrifugal separation by rotation of the cover body and the motor, completely solving the existing nozzle clogging problem, and the generated mist naturally goes into the space between the body and the cover body. It flows out and reflects light through a separate LED lamp, creating a fog of various colors.

The present invention described above has been described with reference to an embodiment shown in the drawings, but this is only exemplary, and various modifications and other equivalent embodiments are possible from those of ordinary skill in the art. Should be clarified. Accordingly, the true technical protection scope of the present invention should be interpreted by the appended claims, and all technical ideas within the scope equivalent thereto should be construed as being included in the scope of the present invention.
