Description

The coating spray liquid dispersion prevention cover for airless spray guns

The present invention relates to a device for preventing scattering of coating liquid for an airless spray gun, and more particularly, to an airless spray gun that applies pressure to the coating liquid in a sealed container when painting the exterior wall of a building so that the coating liquid is sprayed in the form of a mist through a nozzle. It relates to a device for preventing scattering of coating liquid for airless spray guns, which suppresses dripping of the coating liquid inside the shatterproof cover that prevents scattering of the coating liquid during painting and enables rapid drying.

In general, the exterior wall of an apartment is painted with paint to protect it from corrosion and foreign substances, and the paint for painting is exposed to rain and wind and various pollutants and gradually peels off or discolors over time. get old

Therefore, these paints for painting are repainted every 5 to 7 years, and especially for repainting of high-rise buildings, the worker moves the airless spray gun left and right to spray paint while relying on the rope hanging from the roof to perform the painting work. will perform

In addition, a method using an airless spray gun is generally used among various methods of painting the inner and outer walls of a building, which is a paint construction for construction and finishing.

In addition, in the airless spray gun that sprays the coating liquid, an air control valve and an injection liquid control valve are installed on the rear side, and a handle is usually installed on the front side. The liquid is sprayed onto the exterior or wall surface of the hull shell plate or block through the injection nozzle by air pressure.

At this time, the spray liquid is sprayed while spreading in a sectoral shape, and the spray liquid is scattered as soon as it comes into contact with the painted surface and spreads in the opposite direction to scatter, so that the spray liquid not only comes into contact with the operator's body but also scatters to the outside. It contaminates the surrounding air and adversely affects the respiratory system.

In particular, when painting is done in a state of being exposed to the air, severe pollution is caused and fatal obstacles to the surrounding environment are caused, and it has a great effect on the inhalation of toxic particles by workers and pollution around the workplace. .

In order to improve the scattering prevention-related problems for such an airless spray gun, various types of prior art are known in the prior art.

As an example, in Korea Patent Publication No. 10-2007-0045163 (published on May 2, 2007), “In airless spray painting or spray spray painting, air pressure is used to form a high-pressure air layer block on the edge of spray paint, and the space between them By securing a rotating airflow zone in the low-pressure air layer in the

As described above, in Laid-Open Patent Publication No. 10-2007-0045163, a vortex-type low-pressure air layer rotating airflow block is formed around the edge of the spray paint, and the scattering paint particles flying into the atmosphere are applied to the wall or an object on the painting surface by the air rotational force. As a device to prevent paint scattering by the high-pressure air layer, it seals the outside of the low-pressure air layer block with a high-pressure air layer block to block the residual paint particles that are not seated, as well as spraying by the inflow of wind in the air. It aims to provide a structure of a step that can suppress the scattering of paint,

When generating a vortex inside the shatterproof cover, there is a problem in that it is difficult for the existing spraying liquids to be uniformly sprayed inside the scattering prevention cover due to the vortex wind. In addition, there is a problem that an unnecessary component must be added to the work by configuring a separate air line supply on the outside of the shatterproof cover. There is a problem in that it flows into the inside of the vortex and loses the main function of the vortex.

In addition, in Korean Patent Laid-Open Publication No. 10-2011-2161397, an air curtain is formed by air spraying around the outer periphery of the spraying area of the spray gun where the paint is sprayed by attaching to the painting spray gun during the painting operation, so that the paint is applied by the air curtain. It aims to provide an air curtain spray module for preventing paint scattering that can prevent scattering and increase the adsorption rate of paint.

There is a problem in that a separate air injection nozzle needs to be installed on the outer surface of the spray gun, and when the spray angle is adjusted in the longitudinal direction of the spray gun, the user has to arbitrarily adjust and use it.

In addition, in Korean Patent No. 10-2161397, when painting the exterior wall of a building using a spray gun, it is to provide a scattering dust prevention paint spray painting device that can prevent scattering dust made of paint from scattering to the surroundings. purpose, and

In addition, in Korea Utility Model Publication No. 20-0460970, not only the removal and collection of foreign substances is mechanized, but also the removal and collection of foreign substances can be performed at the same time in a single operation, which greatly shortens the time required to improve work efficiency and improve work efficiency.
