At this time, one or more partition plates having a flat plate shape are installed in the transverse direction of the body portion 10 inside the body portion 10 to partition the inside of the body portion 10 into a plurality of spaces. Through this, it is possible to increase the utilization of space inside the body portion 10 and realize miniaturization of the portable surface treatment device.

Preferably, one partition plate is installed inside the body portion 10 to partition the inner space of the body portion 10 into upper and lower portions.

In addition, a grippable handle is formed at the outer upper end of the main body 10, and a wheel 12 is installed at the lower end to freely move the portable surface treatment device in the forward and backward directions or in the left and right directions.

Next, the first storage unit 20 and the second storage unit 30 are hollow structures sealed on all sides and installed in the inner lower space of the main body unit 10. The first storage unit 20 stores medium gas, and the second storage unit 30 stores combustion gas.

Here, as the medium gas, any gas that can be mixed with the surface treatment liquid may be used without limitation. For example, air, nitrogen, helium, neon, argon, krypton, xenon, or a mixture thereof may be used, but preferably air may be used as the medium gas.

At this time, the combustion gas serves to help the combustion of medium gas, and specific examples of the combustion gas include oxygen, hydrogen, hydrogen sulfide, carbon monoxide, methane, acetylene, ethane, ethylene, propane, propylene, isobutane, butane, isopentane, pentane, dimethyl ether, hexane, heptane, octane, benzene, or a mixture thereof, preferably liquefied petroleum gas (LPG) Available.

On the other hand, the vaporization unit 40 is provided in the upper space inside the main body unit 10, and serves to vaporize by heating the liquid chemical for surface treatment.

More specifically, the flame spraying unit 50 burns the medium gas and the combustion gas supplied from the first storage unit 20 and the second storage unit 30, the chemical solution for surface treatment in a vaporized state supplied from the vaporization unit 40, the medium gas, and the combustion gas to inject internal flame, and burns the medium gas and the combustion gas supplied from the first storage unit 20 and the second storage unit 30 to surround the internal flame. Spray external salt.

Meanwhile, the supply line 60 connects the first storage unit 20, the second storage unit 30, the vaporizing unit 40, and the flame spraying unit 50 to provide a flow path for supplying the medium gas, the combustion gas, and the vaporized liquid for surface treatment from the first storage unit 20, the second storage unit 30, and the vaporizing unit 40 to the flame jetting unit 50.

Specifically, the supply line 60 includes a first medium gas supply line 61 connected from the first storage unit 20 to the flame injection unit 50, a second medium gas supply line 62 branched from one side of the first medium gas supply line 61 and connected to the vaporization unit 40, a vaporized chemical liquid supply line 63 connected to the flame injection unit 50 from the vaporization unit 40, and the second storage A first combustion gas supply line 64 connected to the first medium gas supply line 61 from the unit 30, and branched from one side of the first combustion gas supply line 64 to the vaporized chemical liquid supply line 63.

As is well known, a vortex tube is a device that separates and outputs the flow of compressed air supplied without the need for electricity or separate power into hot air and cold air, and is widely used for local cooling or heating in industrial sites or laboratories due to this energy separation effect.

Therefore, since the vortex tube (not shown) forms a part of the second medium gas supply line 62, the medium gas passing through the vortex tube (not shown) is supplied to the vaporizer 40 in a preheated state, thereby improving the vaporization efficiency of the vaporizer 40.

On the other hand, an FRL unit (Filter-Regulator-Lubricator unit, 71) is additionally installed on the first medium gas supply line 61 connected from the first storage unit 20 to filter moisture and foreign substances contained in the medium gas flowing through the medium gas supply line, and at the same time to control the flow pressure.

4 is a cross-sectional view showing a vaporizing unit of a portable surface treatment device according to a preferred embodiment of the present invention.

As shown in FIG. 4 , the vaporizing unit 40 includes a housing 41, a turbulence generating unit 42, a chemical storage unit 43, a heating and mixing unit 44, and a heating means (not shown).

The housing 41 is a structure forming the exterior of the vaporizing unit 40, and the turbulence generating unit 42, the chemical storage unit 43, and the heating and mixing unit 44 are installed inside.

The turbulence generating unit 42 includes a medium gas inlet pipe 42-2, one end of which is connected to the second medium gas supply line 62 through the medium gas inlet 42-1 and the other end connected to the chemical storage unit 43 through the medium gas outlet 42-3.

In addition, the heating means (not shown) for heating the medium gas is installed on one side of the turbulence generating unit 42 .

Here, the medium gas flowing into the vaporizing unit 40 is used to promote the vaporization of the liquid chemical for surface treatment. In order for the medium gas to fully play its role, the medium gas inlet pipe 42-2 may be formed in a multi-bent shape.

The gaseous medium gas passing through the medium gas inlet pipe 42-2 collides with the bent portion of the medium gas inlet pipe 42-2 to form a turbulent flow, and when the medium gas flowing in turbulent flow is supplied to the liquid chemical storage unit 43, the vaporization efficiency of the vaporizing unit 40 can be increased because the heat diffusion effect is greater than that of the medium gas flowing in a laminar flow.

On the other hand, the chemical storage unit 43 is a kind of chamber structure in which a chemical storage space for surface treatment is stored, and a chemical solution inlet 43-1 into which the chemical solution for surface treatment is introduced from the outside is formed on one side, and a chemical outlet 43-2 for discharging the chemical solution for surface treatment to the outside is formed on one side, and the heating means (not shown) installed on one side serves to heat and vaporize the chemical solution for surface treatment to a predetermined temperature. do

Next, the heated mixing unit 44 has one end connected to the chemical storage unit 43 through the vaporized chemical liquid inlet 44-1 and the other end connected to the vaporized chemical liquid supply line 63 through the vaporized chemical liquid outlet 44-3. A vaporized chemical liquid discharge pipe 44-2 is provided, and the chemical liquid for surface treatment in a vaporized state of the chemical liquid storage unit 43 and the first storage tank 2 The medium gas supplied from 0) passes through the vaporized chemical liquid discharge pipe 44-2, is heated and mixed, and is discharged.

At this time, the vaporized chemical liquid discharge pipe 44-2 is formed in a multi-bent shape, and the chemical liquid for surface treatment and the medium gas in a vaporized state flowing along the vaporized chemical liquid discharge pipe 44-2 collide with the bent portion of the vaporized chemical liquid discharge pipe 44-2 to form turbulent flow, thereby increasing the residence time in the vaporized chemical liquid discharge pipe 44-2 to increase the mixing ratio.

In addition, the heating means (not shown) is installed on one side of the heating and mixing unit 44 to prevent re-liquefaction of the chemical solution for surface treatment in a vaporized state passing through the vaporized chemical solution discharge pipe 44-2.

The heating means (not shown) heats the inside of the heating and mixing unit 44 and the chemical storage unit 43 to a predetermined temperature so that the surface treatment liquid is smoothly vaporized, and may be formed of various known heating means including a separate device such as a mantle heater.

On the other hand, the vaporizing unit 40 may further include a spray nozzle 43-3 installed on one side of the chemical storage unit 43 to spray the chemical solution for surface treatment into the chemical storage unit 43, and a spraying chemical solution supply pipe 43-4 for supplying a part of the chemical solution for surface treatment contained in the chemical storage unit 43 to the spray nozzle 43-3.

Since the liquid chemical storage unit 43 is a closed structure, the internal pressure increases as the heat of vapor inside increases, and as a result, the boiling point of the chemical liquid for surface treatment stored therein rises and the vaporization efficiency decreases.

Therefore, the spray nozzle 43-3 and the spray solution supply pipe 43-4 are additionally installed in the chemical storage unit 43 to spray the chemical solution for surface treatment into the chemical storage unit 43. By doing so, the boiling point of the water-soluble wastewater is induced not to rise through the cooling effect, thereby increasing the amount of evaporation.

In addition, a chemical storage information display means (not shown) is installed on one side of the chemical storage unit 43 to display the storage amount of the chemical solution for the surface treatment device stored in the chemical storage unit 43 .

The chemical storage information display means (not shown) is provided in a single pipe structure including a transparent portion through which the water level can be checked from the outside over a certain area, and is connected to the side of the chemical storage unit 42 to form a communication structure, so that it has the same water level as the storage level of the chemical liquid for surface treatment stored in the chemical storage unit 43, but is not limited thereto.

Therefore, the liquid chemical storage information display means (not shown) may be implemented in a manner in which numerical data on the storage level and storage amount of the chemical liquid for surface treatment stored and stored in the chemical liquid storage space of the chemical liquid storage unit 43 is stored and stored through a separate sensing module such as a separate water level sensing module or a volume sensing module, and provides the corresponding data information to the operator through a separate output module.

Through this, the operator can immediately and efficiently supply and manage the chemical solution for the surface treatment apparatus by checking the information and information on the storage level and storage amount of the chemical solution for surface treatment stored in the chemical storage space of the chemical storage unit 42 provided by the chemical storage information display unit (not shown).

At this time, the hose body 54 is formed of a flexible material so that the operator can freely move within a certain radius while holding the flame spraying part 50 during surface treatment.

On the other hand, the other end of the hose body 52 is formed in a form capable of gripping the handle member 54 .

Preferably, one end of the handle member 54 is coupled, and the first medium gas supply line 61 and the vaporized chemical liquid supply line 63 are installed therethrough.

In addition, the dual burner 56 is coupled to the other end of the handle member 54 and connected to the first medium gas supply line 61 and the vaporized chemical liquid supply line 63.

In addition, an ignition button 58 protruding outward is formed on one side of the handle member 54 to operate an ignition unit (not shown) supplying ignition sparks to the dual burner 56.

On the other hand, the double burner 56 includes an internal flame burner unit 56-2 supplied with the chemical solution for surface treatment in a vaporized state mixed with combustion gas and medium gas to a first collecting space 56-3 provided therein, and the second collecting space 56-5 by accommodating the internal flame burner unit 56-2 in a second collecting space 56-5 provided therein and surrounding the outside of the internal flame burner unit 56-2. An external flame burner 56-4 to which combustion gas and medium gas are supplied is provided to spray the external flame in a form surrounding the internal flame and the internal flame.

At this time, the double burner 56 is disposed at equal intervals under the first collecting space 56-3 and the lower part of the second collecting space 56-5, and is formed in a corrugated plate shape, and may further include a spray path forming plate 56-6 facing each other to form an open spray path.

More specifically, the spray path forming grooves formed in the vertical direction along the wrinkles formed on the spray path forming plate 56-6 correspond to each other to form the open spray path between the spray path forming plates 56-6, thereby guiding the inner flame and the outer flame to be sprayed with straightness.

The other end is formed in a tubular shape and coupled to the double burner 56 so that the double burner 56 can rotate at the front end of the handle member 54.

When the dual burner 56 is fixedly coupled to the front end of the handle member 54, the inner flame sprayed from the dual burner 56 and the outer flame sprayed from the dual burner 56 according to the movement of the operator holding the handle member 54. Since the spray angles change, uniform surface treatment ability cannot be secured.

Therefore, the rotating part 55 is rotatably installed at the front end of the handle member 54 in a state in which it is fixedly coupled to the double burner 56, so that the double burner 56 maintains its posture by its own weight even when the handle member 54 moves vertically or left and right, and can spray the inner flame and the outer flame having straightness forward, and furthermore, during surface treatment, fatigue applied to the operator's wrist depending on the size and fixing position of the material can alleviate

At this time, a weight may be additionally provided on one side of the double burner 56 to give a center of gravity to the lower part of the double burner 56 .

In addition, a portion of the front end of the handle member 54 is cut to facilitate insertion and coupling of the pivoting part 55, and in addition, a fixing cap 54-2 is coupled to the front end of the handle member 54 to prevent the pivoting part 55 from being separated from the handle member 54.

Here, the fixing cap 54-2 has a screw thread formed on the inner circumferential surface of the handle member 54 and is fastened with a screw thread formed on the outer circumferential surface of the handle member 54, so that it can be easily fixedly coupled to the handle member 54.
