Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a paint booth that collects paint mist using water or a collection liquid (hereinafter simply referred to as liquid).

In general, the paint mist suction airflow sucks the liquid at the surface of the liquid into the swirl chamber, and the water film formed in the swirl chamber and the paint mist collected by water droplets are used in the paint booth. Unlike conventional methods, there is no need to circulate water using a pump, so there is no clogging of nozzles, piping, etc., and it has the advantage of high collection efficiency.

However, as shown in FIG. 1, the paint sludge collected by the liquid returns from the swirl chamber together with the liquid to the front of the liquid tank 3 via the collecting tray 1 at the rear via the return pipe 2. During this time, there was a lot of paint sludge adhering to the swirl chamber, saucer, and return pipe, floating of paint sludge to the rear of the swirl chamber, and precipitation, which was difficult to clean due to its structure and required a great deal of time and effort.

Among these devices, there is a device that has a sludge tank section 4 on the back of the booth and a cleaning lid 5 to remove paint sludge that has floated or settled at the rear of the swirl chamber, but this is uneconomical in terms of installation space and equipment costs. . In addition, for cleaning the swirl chamber, there is a type in which the front plate 6 is opened, but this method hardly solves the difficulty of cleaning.

In view of the above-mentioned circumstances, the present invention aims to simplify cleaning, which has been a problem, in order to take full advantage of the advantages of this type of bath, which has good collection efficiency and does not require pumps or piping. .

That is, the present invention enables the mist collection device section of a paint booth that uses liquid to collect paint mist to be separated from the main body.

Hereinafter, the present invention will be explained with reference to drawings of embodiments.

In FIGS. 2 and 3, the main body 10 is the front plate 11.
The processing room 12 is divided into a processing room 12 and a painting room 13.
A fan 14 for sucking mist is provided in communication with the.

Further, a water tank 15 is formed at the bottom of the booth body 10. The mist collection device 16 has a continuous text surface 17 separated from the front plate 11, a saucer 18 with the lower part of the text 17 bent backwards, a spiral plate 19 formed in an arc shape to enclose the saucer 18, An inclined plate 20 that extends continuously from the lower end of the spiral plate 19 into the front liquid, and a frame 21 that fixes these.
and supporting legs 22 and the like. In addition, a return pipe 23 for returning the liquid and sludge accumulated in the saucer 18 to the water tank is provided as appropriate depending on the frontage of the painting room. Further, the legs 22 are configured to have a spherical tip so as to make point contact in order to facilitate pulling out. 24 indicates an eliminator.

Next, to explain this effect, first, when the paint mist sprayed into the painting chamber 13 is sucked into the fan 14, it is affected by the high-speed airflow generated in the gap between the inclined plate 20 at the water surface A part and the lower end opening of the saucer 18. The liquid thus sucked forms a liquid film on the inner surface of the swirl plate 19 of the swirl chamber C, and the paint mist collides with this liquid film and is collected.

Further, the paint mist is collected by contacting or colliding with the countless droplets generated by the liquid scattering from the end of the spiral plate 19 and breaking when it hits the vertical surface 17 and the eliminator 24. Next, the liquid that has been sucked and collected the paint mist is returned from the saucer 18 to the front of the water tank through the return pipe 23, and the liquid that has gone around to the rear of the spiral plate 19 is
It is returned to the lower water tank 15 as it is. However, in this case, due to long-term use, paint sludge adheres to the swirl plate 19, elevation 17, eliminator 24, return pipe 23, etc., and sludge accumulates in the water tank, making it impossible to obtain the desired performance. need to be cleaned. For this reason, in the present invention, the mist collecting device portion fixed to the frame 21 is pulled out from the booth body 10 so that cleaning can be performed in a wide area. As mentioned above, in the present invention, the mist collection device part, which is an important part in a painting booth, was not previously configured to be separated from the main body, but it is integrated with a frame and can be separated from the main body. It is now extremely easy to clean not only the collection device, but also the inside of the processing room and water tank, especially the rear part, and it can be done in a short time and cleanly, and the biggest problem with conventional booths of this type has been solved. Ta.

Incidentally, this spiral plate can be freely opened/closed or removed for easier cleaning.
