Description

[Detailed description of the invention] (Industrial application field) The invention relates to a simple painting booth for spray painting, etc. More specifically, the invention is a simple painting booth for spray painting, etc., and more specifically, it allows excess paint mist to flow down from a flow plate and is air-filled. This invention relates to a simple wet-type painting booth that transfers paint mist to an aqueous phase and removes it by passing it through water that has been atomized or dropped by suction.

(Prior art) In general, a wet type simple painting booth is constructed by applying water onto a flow plate and allowing it to flow down, receiving the flowing water in a water tank below the plate, and sucking air using a fan etc. to create a mist due to the bench lily effect. This mechanism removes excess paint mist by atomizing it into water or droplets, and passing the oversprayed paint mist during painting through the atomized or droplet water. be.

In a simple wet painting booth, it is necessary to remove paint components that float or become cloudy in the water in the aquarium. For this reason, in the past, for example, a circulation channel was formed to collect the water in the aquarium and then return it to the aquarium, and a pump was used to circulate the water.At this time, a strainer installed in the circulation channel was used to remove paint components contained in the water. A commonly used method is to remove .

(Problem that the invention aims to solve) However, in the conventional method, some of the paint components taken into the aquarium that float on water remain on the water surface of the aquarium for a long time, and it is difficult to collect them outside the aquarium. It is often difficult to do so, and paint components may dry and adhere to the walls of the circulation channel, which may obstruct the circulation of water.

The present invention aims to solve the above-mentioned problems and provide a simple wet-type painting booth that can effectively remove paint components floating in water in an aquarium without causing paint components to adhere to waterways. It is something to do.

(Means for solving the problem) The simple wet painting booth of the present invention has a water tank installed in the paint booth to receive water flowing down from the flow plate, and a water tank formed on the front side of the water tank to receive water flowing down from the water tank. a drain channel through which water flows through; a strainer detachably attached to the drain channel to allow overflow water from the water tank to pass through; a water injection pipe for injecting water into the rear side of the water tank; and a center of the water tank. A riser pipe that is piped above the water tank and has a plurality of injection ports facing toward the front side of the water tank, and a circulation pump system that collects water from the drainage channel and returns it to the water injection pipe and the riser pipe. It is something.

The strainer used in the present invention may be, for example, a conventionally used paint strainer. An example of a simple strainer is one in which a wire mesh, preferably 5 to 50 meshes, is stretched over a rectangular frame.

(Function) In the painting booth of the present invention, recovered water flowing out from the water tank by operation of the circulation pump is returned to the water supply pipe and the water supply tank to the flow plate at the rear of the water tank. Therefore, in the water tank, a water flow is formed that flows from the rear of the tank to the front side of the tank, thereby discharging paint components and foreign matter that are turbid or suspended in the water to the outside of the tank. Moreover, in the present invention, the riser pipe is arranged above the center of the aquarium, with each of its injection ports facing the front side of the aquarium,
In addition to the flow of the aquarium water, the force of the water jetted from the riser pipe causes paint components and the like floating on the aquarium water surface to be sent to the front side of the aquarium and discharged out of the aquarium.
Therefore, according to the present invention, paint components and foreign substances floating on the water surface of the aquarium can be effectively flushed out of the aquarium without leaving them in the aquarium.

In addition, the paint booth of this invention is equipped with a strainer in the drainage channel on the front side of the water tank, and the overflow water from the water tank passes directly through the strainer, making it possible to remove paint components and foreign objects floating in the water. . Furthermore, by installing the strainer at the height of the periphery of the aquarium, that is, at a position lower than the water level in the aquarium, and adjusting the amount of water circulation so that the water level in the drain channel is maintained above the strainer, the strainer can float on the water. It is possible to prevent paint components etc. from drying and sticking to the strainer. Furthermore, in the painting booth of the present invention, the strainer is detachably attached, making it easy to replace and clean the strainer.

(Example) Embodiments of the present invention will be described below with reference to the drawings.

As shown in FIGS. 1 and 2, the simple wet painting booth of the embodiment includes a flow plate 1, a rectangular water tank 2, and a painting work floor 10 in front of the water tank 2. In addition to the water supply tank 11, a fan 12 is installed above the flow plate 1, and a demister 1 is installed below the fan 12.
3 and a collision plate 14. Therefore, as shown in FIG. 1, when worker A stands on the floor 10 and spray-paints the object 15 in front of the flow plate 1, the water overflowing from the tank 11 is caused to flow down onto a flow plate 1, and a fan 12 is rotated at the same time to suck air, and the water flowing down from the plate 1 to a water tank 2 is atomized or dropped by a bench lily effect. Then, most of the oversprayed paint mist 16 is taken into the atomized or dropletized water and transferred into the water tank 1.

In the painting booth of the embodiment, the height of the front side edge 18 of the water tank 2 is designed to be lower than that of the other edges,
In addition, a drainage channel 3 is formed on the front side of the water tank 2 so as to be adjacent to the tank 2, and the water in the water tank 2 overflows from the front side edge 18, flows into the drainage channel 3, and is discharged from the outlet 19. It's starting to leak out. moreover,
In this painting booth, strainers 4, 4 each having a structure in which a 20-mesh wire mesh is attached to a frame are placed in the drainage channel 3 at a position lower than the top surface of the front side edge 18 (Fig. 1).
It is installed horizontally and removably, so that overflow water from the water tank 2 can directly pass through.

In addition, in the painting booth of the example, the water injection pipe 5 is piped to the rear side of the water tank 2 along the longitudinal direction of the tank 2,
The outflow ports 6 of the pipes 5 are formed almost regularly toward the front side of the water tank 2, and the riser pipes 7 are arranged above the center of the water tank 2 along the longitudinal direction of the tank 2. The injection ports 8 of 7 are provided almost regularly toward the front side of the aquarium. Furthermore, in this paint booth,
A water pipe 23 is provided to send water to the water supply tank 11 (FIG. 1).

In addition, in the painting booth of the embodiment, as shown in FIG.
and a circulation waterway connected via valves 20, etc., water in the drainage channel 3 is recovered by operation of the pump 9, and filtered with high precision by a filter 24.
Thereafter, it is returned to the water injection pipe 5, riser pipe 7, and water supply pipe 23 again.

By operating the pump 9, water is circulated, and in the water tank 2, a water flow 21 is formed from each outlet 6 of the water injection pipe 5 toward the front side of the tank, and paint components that become turbid or suspended in the water are removed. etc., overflow from the edge 18 of the water tank 2 and are discharged together with the water. Furthermore, in the painting booth of the embodiment, water is ejected from each injection port 8 of the riser pipe 7, and waves 22 spreading toward the front of the water tank are formed on the water surface L.
(Fig. 1, Fig. 2). Then, due to the force of this wave 22 in addition to the water flow 21,
Paint components and foreign matter floating on the water surface L are sent out to the front side of the water tank 2 without remaining in the water tank and are discharged onto the strainer 4. At this time, in the embodiment, since the position of the strainer 4 is below the water level L of the aquarium water, the drainage channel 3 is adjusted by adjusting the amount of circulating water.
The water level can be maintained above the strainer 4. Therefore, even after long-term operation, there was no problem of floating paint components drying and sticking to the strainer 4, clogging its mesh, and obstructing water flow. Moreover, the problem of sticking of paint components did not occur in the above-mentioned circulation waterway. Furthermore, by removing and replacing the strainer 4 after an appropriate period of time, the overcapacity of the strainer 4 could always be maintained at a good level.

(Effects of the invention) As explained above, the simple wet painting booth of the invention uses the force of the jet water in addition to the water flow formed inside the aquarium to send floating matter on the surface of the aquarium out of the aquarium. By having a structure in which the flowed water is directly passed through a removable strainer, paint components and foreign matter floating on the water surface of the aquarium can be removed without causing problems such as remaining in the tank or drying out.
Strainers can be removed very effectively, and the strainer is easy to replace and clean.
