Embodiment Construction
[0020] An embodiment of the present invention will be described below using the drawings.
[0021] Figure 1 is a sectional view seen from the side of the spray booth. Water tank 1 provided in the lower part is divided into front water tank 1A and rear water tank 1B. The central part is provided with a paint mist treatment chamber 3, and the upper part is provided with an exhaust fan 4. A bucket 5 is provided above the processing chamber 3 , and a flow plate 6 hangs down below the bucket 5 . Considering the convenience of manufacture and maintenance of the water flow plate 6 , the water flow plate 6 is composed of an upper water flow plate 6A and a lower water flow plate 6B.
[0022] The lower end of the lower water flow plate 6B is provided with a suction port 7, which is formed to allow the suction air flow of the aforementioned exhaust fan 4 to flow in at a suitable flow rate. The paint mist treatment chamber 3 becomes the passage of the suction airflow of the exhaust fan...

The object of the present invention is to improve the collecting efficiency of paint mist applied by showering, more water being used to circulate in a front water-flow board and a showering nozzle. But an inner wall extending from a sucking port of a lower part of the water-flow board to a showering portion is easily adhered by the paint so as to cause problems in cleaning. In addition, the noises caused by water flow and collision gives an unpleasant impression to worker, and brings adverse effect to the environment. This invention intends to solve these problems. The solution of the present invention is to provide a gutter which receives the showering liquid which was injected for processing the interior for collecting paint mist, where a portion of the showering liquid flows back to a tank, and the remainder overflows along a longitudinal direction of the gutter to make the flow downwards along the vertical aspect of a liquid flow-board. The inside of the liquid-flow board consists of a two-level top and bottom configuration. On a front of the top level is provided with a first level liquid-flow board. On a rear lower part is provided with a second level liquid-flow board. Between the first and second water-flow boards are formed with incoming air sucking passages for sucking air flow to flow through. The bottom of the second level liquid-flow board is constructed in such a manner to merge into a lower part of the liquid flow.
Description
technical field [0001] The invention relates to a spray booth, which can collect and recycle the paint spray that does not stick to the object to be coated during spraying, and especially relates to a water-washing spray booth. The chamber uses exhaust fans to attract paint spray and airflow at the same time, and then uses spray water to collect and process paint spray to discharge clean air. Background technique [0002] Common water-washing spray booth is shown in Figure 4, and its bottom is provided with water tank 45, utilizes exhaust fan 41 to suck in the airflow that contains paint mist in front of the spray booth, when passing through paint mist treatment chamber 43, spray out from nozzle 44 The water washing spray will make the paint mist and water fall to the lower water tank for collection, and the water sucked up by the water pump (not shown) will be supplied to the aforementioned nozzle 44, and at the same time, it will be supplied to the bucket that overflows th...
