[0001] Spray gun for vessel [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spraying apparatus, and more particularly, to a spraying apparatus for a ship capable of preventing scattering of paint and reducing waste of paint.

Sprayers are often used in shipyards where ships are built. For example, the spraying apparatus is used to coat the surface of a ship or to coat a coating containing a specific component so that various seaweeds and shellfish do not adhere to the surface of the ship.

However, the paint used in the drying process of the ship contains a considerable amount of harmful substances to human and living organisms. However, since the conventional spray apparatus for spraying a paint widely spreads, a considerable amount of paint splashes into the air and contaminates the surrounding air. In addition, a conventional spray apparatus for a ship has a problem in that a considerable amount of paint is scattered into the air as described above, causing waste of the paint.

Therefore, it is urgently required to develop a new type spray device capable of solving or minimizing the above problems.

On the other hand, Patent Document 1 is a prior art related to a spraying apparatus. Patent Document 1 discloses a spray gun suitable for using a water-soluble paint containing zinc. However, Patent Document 1 does not disclose any structure or method that can prevent the water-soluble paint from scattering to the surroundings.

1 to 3, a marine spray apparatus according to an embodiment of the present invention will be described.

The marine spray apparatus 100 according to the present embodiment may include a first nozzle 110 and a second nozzle 120. In addition, the marine spray apparatus 100 may further include a paint supply unit 150 and an air supply unit 160, and may optionally include an operation unit 170 for controlling spraying of paint and air.

The first nozzle 110 may be mounted in front of the marine spray device 100. In other words, the first nozzle 110 may be located at the center of the injection port 102 as shown in FIG. At least one first nozzle hole 112 may be formed in the first nozzle 110. Here, the first nozzle hole 112 may have a cross-sectional shape that gradually decreases or increases abruptly toward the front along the longitudinal direction of the first nozzle 110. However, the cross-sectional shape of the first nozzle hole 112 is not limited to the above-described shape, and may be changed to other shapes. The first nozzle 110 may be connected to the paint supply unit 150. Therefore, the paint can be sprayed through the first nozzle hole 112 of the first nozzle 110. [ Here, the spraying of the paint through the first nozzle 110 can be controlled by the operating portion 170.

The second nozzle 120 may be mounted in front of the marine sprayer 100 in the same manner as the first nozzle 110. In other words, the second nozzle 120 is disposed in parallel with the first nozzle 110, and may surround the first nozzle 110 as shown in FIG. A plurality of second nozzle holes 122 may be formed in the second nozzle 120. In other words, the plurality of second nozzle holes 122 can be arranged around the first nozzle hole 112 in a circular shape. Here, the second nozzle hole 122 may have a cross-sectional shape gradually decreasing or suddenly expanding toward the front along the longitudinal direction of the second nozzle 120. However, the cross-sectional shape of the second nozzle hole 122 is not limited to the above-described shape, and may be changed to other shapes. The second nozzle 120 may be connected to the air supply unit 160. Therefore, air can be injected through the second nozzle hole 122 of the second nozzle 120. [ Here, the injection of air through the second nozzle 120 can be controlled by the operation unit 170. [

The paint supply unit 150 may be connected to the paint storage tank and the first nozzle 110. Accordingly, the paint stored in the paint storage tank can be supplied to the first nozzle 110 through the paint supply part 150.
