Figure 5 is a detailed view of the filter portion of the model spray booth according to the present invention, Figure 5 (a) is a plan view and a side view of the paper filter (221, 321) to prevent rapid contamination of the dust filter (222,322), Figure 5 (b ) Is a plan view and a side view of the dust filters 222 and 322 which filter out only dust of the paint, and FIG. 5 (c) is a plan view and a side view of the compressed active filters 223 and 323 for self-purifying organic gas.

Figure 6 is an embodiment of a spray booth for a model according to the present invention, when explaining the implementation method of the model spray booth of the present invention configured as described above are as follows.

First, the door 12 coupled to the front opening of the case 10 by the magnet 12a is opened, and the model 70 is mounted on the lower filter part 20 inside the model spray booth. Can be used to support the flat pedestal 71 according to the shape of.

After mounting the model 70 therein, the plug 53 of the cable 52 connected to the control box 50 at the rear of the case 10 is connected to a power supply (not shown), and the switch 51 When turned ON, the light bulb 16 inside the case 10 connected to the cable 52a is turned on, and the pair of auxiliary exhaust fan 41 and the main exhaust fan 42 connected to another cable 52b are turned on. Is rotated in one direction.

After the switch 51 is turned on as described above, the painting work of the model 70 is performed by using the airbrush 80 connected to an external spray supply device (not shown).

At this time, the air flow inside the model spray booth is a gas or liquid paint sprayed from the air brush 80 as shown in the plan view of Figure 7 (a) and side cross-sectional view of Figure 7 (b) and the lower part of the case 10 and By passing through the lower filter unit 20 and the rear filter unit 30 provided on the rear side, various dusts and organic solvents due to painting are removed to be discharged to the atmosphere.

The inlet flow rate flowing into the opening of the case 10 in the state in which the door 12 of the case 10 is separated is 0.6 to 0.7 m / sec since the work is performed indoors without any influence from the outside. By providing a margin of about 20% more than 0.4m / sec of the technology (see Labor Notification 90-45), the exhaust performance is improved by collecting and discharging pollutant from the booth entrance.

In addition, the total exhaust air volume of the model spray booth discharged to the outside according to the operation of the auxiliary exhaust fan 41 and the main exhaust fan 42 is 5.5m ³ / min, the total exhaust air pressure acting in the booth is 47 mmAq, the pressure loss of 10 mmAq (at the duct flow rate 12 m / sec) from the dynamic pressure, the pressure of 20 mmAq applied to the lower and rear filter parts, and the 15 mmAq pressure loss from the discharge flexible hose 44 of Φ 100 x 5 m Since the applied wind pressure is 45 mmAq, the wind pressure of 47 mmAq of the main exhaust fan 42 is set in consideration of the combined wind pressure to which the pressure loss is applied.

Therefore, it is possible to reduce the vortex phenomena at the time of painting the model 70 by arranging the air volume and the wind pressure, thereby bringing an effect of improving the quality of the painted surface, and can also prevent paint consumption due to excessive exhaust.

The air volume control guide plate 45 is exhausted through the second filter layer 32 and discharged to the auxiliary exhaust fan 41, and exhausted through the first filter layer 22 under the case 10. It prevents backflow due to the collision and adjusts the amount of exhaust discharged from each of the first and second filter layers 22 and 23 to help guide the main exhaust fan 42 to facilitate the flow of the exhaust.

When the spraying operation of the model 70 is completed, the detached door 12 is attached to the front of the opened case 10, and the auxiliary exhaust fan 41 and the main exhaust fan 42 are operated for a predetermined time. Various dust and organic solvents remaining inside the booth are discharged.

Looking at the first and second filter layers 22 and 23 through which various dusts and organic solvents pass during the spraying operation, the paper filters 221 and 321 remove 90% or more of the paint dust sprayed or blown with the consumable filter. This is a consumable filter that performs a primary function of minimizing dust discharged to the atmosphere with extension of replacement cycles of the dust filters 222 and 322, and the dust filters 222 and 322 are 10% of which are not removed from the paper filters 221 and 321. The filter performs a secondary function of completely removing the dust discharged to the final atmosphere by removing the paint dust, the pressing active filter (223, 323) is not removed by the paper filter (221, 321) and dust filter (222, 322) It is a filter that performs the odor removal function of absorbing and removing organic solvents (Voc).

8 is an electrical circuit diagram of the spray booth for the model according to the present invention, the power supplied through the plug 53 is the auxiliary exhaust fan 41 and the main exhaust fan 42 in accordance with the ON / OFF control of the switch 51 And supplying power to the bulb 16 to control its operation.

While the invention has been shown and described with respect to particular embodiments, it will be apparent to those skilled in the art that various modifications and variations can be made without departing from the spirit and scope of the invention as set forth in the appended claims. Anyone can grow up easily.

As described above, the present invention is a forced exhaust type spray booth for preventing indoor pollution due to painting in the room and a user's comfortable environment, and a filter composed of a paper filter, a dust filter, and a crimping active filter on the lower and rear sides of the booth. It is equipped with the air to remove various dust and organic solvents due to painting and discharge it to the atmosphere to prevent air pollution, and the simultaneous exhaust system of the lower and rear to prevent backwind due to dust and dust of paint that is heavier than air have.
