Abstract

(57) [Summary] [Purpose] To provide a coating mist treatment device that reduces the load on the filter installed in the exhaust duct of the coating booth, facilitates maintenance, and does not discharge the paint into the surrounding atmosphere. To do. [Structure] The coating mist is washed away and stored in a settling tank, and the paint retained in the settling tank is solidified by a pressing machine and discharged.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a treatment device for discharging coating mist generated in a coating booth in an automobile coating factory.

[0002]

[Prior art]

 Conventionally, in a car repair shop or the like, a car is installed in a closed paint booth to perform the painting work. In such a coating booth, in order to ventilate the inside of the booth, a vertical pumping type is used in which outside air is supplied from the top of the coating booth and discharged from the lower pit. In this case, the coating mist floating in the air in the booth is sucked into the exhaust duct through the pit by the suction force on the pit side, and is filtered and removed by the filter installed in the middle of the exhaust duct to clean the mist. Only the converted air is released to the outside.

[0003]

[Problems to be solved by the device]

 As described above, conventionally, the coating mist is filtered by the filter to prevent the mist from being discharged to the outside and contaminating the surrounding air. However, such a structure has a problem that the filter in the duct is clogged at an early stage, and therefore frequent maintenance is required.

The present invention solves such conventional problems, reduces the load on the filter installed in the exhaust duct of the coating booth, facilitates maintenance, and discharges the coating material into the surrounding atmosphere. The aim is to provide a coating mist treatment device that does not have such a problem.

[0005]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention proposes a settling layer for storing a coating mist, a wash-out pit inclined so as to wash away the coating mist that has fallen in a coating booth and collect it in the settling layer, and a coating material in the settling layer. It is characterized by comprising a press that separates and solidifies the water.

[0006]

[Action]

 The coating mist in the coating booth stays in the sedimentation layer and is almost completely solidified by the press machine before being discharged, so the load on the exhaust filter can be greatly reduced.

[0007]

【Example】

 In the figure, (1) is a coating booth, and a suction space (3) partitioned by a ceiling filter (2) is formed in the ceiling portion of the coating booth (1). Reference numeral (4) is a suction duct for introducing outside air into the suction space (3), and the suction fan (5) provided in the middle of the suction duct (4) introduces the outside air into the suction space (3). Is introduced. (6) is a suction filter provided in the middle of the suction duct (4) on the upstream side of the suction fan (5).

On the floor of the coating booth (1), groove-like washout pits (7) and (7) are formed on both sides parallel to the flow direction of the outside air sucked by the suction duct (4). ing. A precipitation layer (9) is formed along the wall surface of the wash-out pits (7) (7) opposite to the suction duct (4). This settling layer (9) communicates with the wash-out pits (7) and (7), and the bottom thereof is lower than that of the wash-out pit (7). Further, the wash-out pit (7) has an inclined bottom (10) which is lowered toward the sedimentation layer (9), and a wash-out nozzle (11) for jetting water toward the bottom (10). ) (11) is installed at the required location along the longitudinal direction. (13) (13) is a grating that covers the washout pit (7), and (14) is a grating that covers the precipitation layer (9). Further, a suction pipe (19) of a filter press (18) installed outside the coating booth (1) is exposed to the bottom of the settling layer (9) through the suction pipe (19). The coating mist in the settling layer (9) is sucked out to the filter press (18).

Reference numeral (15) is an exhaust duct communicating with the settling layer (9). An exhaust fan (16) is provided in the middle of the exhaust duct (15), and a downstream side of the exhaust fan (16) is provided. An exhaust filter (17) is installed in.

In the above, the outside air introduced into the suction space (3) by the suction duct (4) is supplied to the booth (1) after removing small dusts such as dust by the ceiling filter (6). . Then, the coating mist generated in this booth (1) passes through the gratings (13) and (13) by the suction force on the side of the exhaust duct (15) and falls into the washing pit (7). In the wash-out pit (7), water ejected from the wash-out nozzle (11) collects in the sediment layer (9) by the inclined bottom (10) of the wash-out pit (7). . The mixture of water and paint collected in the settling layer (9) is sucked into the filter press (18) by the suction pipe (19), and the paint separated from water in the filter press (18) solidifies. It is collected and discarded. Then, on the exhaust duct (15) side, the remaining coating mist that is not sucked to the filter press (18) side in the settling layer (9) is sucked, but most of it is on the filter press (18) side. Since it is sucked, the paint mist that goes out to the exhaust duct (15) side is greatly reduced, the load on the exhaust filter (17) can be greatly reduced, and it is also effective as a pollution control measure to the neighborhood. .

[0011]

[Effect of device]

 As described above, in the present invention, most of the coating mist generated in the coating booth is solidified and discharged by the press, so the load on the filter in the exhaust duct can be significantly reduced, and maintenance such as filter replacement can be significantly reduced. The effect is that it can be simplified. In addition, since it is solidified and discarded in this way, it is also effective as a pollution control measure for the neighborhood.
