Definitions

  • the present invention relates to an arrangement in spray painting booths, in which supplied ventilating air is extracted to a subsequent drop collector through a horizontal slot.
  • the slot is located at the bottom of the booth along and below one or more vertical or inclined internal walls sprinkled with water.
  • the slot is formed between a lower edge of the internal wall which curves toward the booth, and a substantially vertical flange attached to a substantially horizontal plate disposed above a liquid tank underlying the internal wall.
  • a primary object of the present invention is to eliminate the above-mentioned disadvantage by mixing a greater percentage of the water with the paintor dust-laden air. This is achieved essentially by providing an extension on the horizontal plate in front of the extraction slot.
  • the improved technical effect is mainly due to the fact that the water which flows past the slot and down onto the splash plate is dispersed by impingement, as it drops on the same. In this manner, a number of droplets of water will be carried away into the slot orifice, and at the same time, the lower part of the slot becomes wet and assists in increasing the intake of water through the slot.
  • the spray painting booth is provided with an internal upstanding side wall 11 curving inwardly of the both at its lower end and overlying a substantially horizontal plate 12 disposed in spaced relation above a tank of liquid 5 which underlies the wall.
  • a slot 1 is 3,390,400 Patented June 25, 1968 "ice formed between a depending lip 2 at the lower terminus of the Wall 11 and a substantially vertical flange 4, which is attached to the plate 12.
  • the plate 12 extends inwardly of the booth and forms a splash plate 3 in front of the slot 1. Ventilating air passes through the slot 2 laden with paint particles which bind to water droplets passing over the lip 2. Thereafter, the heavier agglomerate of paint and water mix is extracted, whence the clean air, after passing by the baffles 13, is discharged through an opening 7.
  • the plate 12 is provided with a baflle 6, extending down into the liquid tank 5, and having an upward extension 611 joining the plate 12 to define a trough.
  • the upstanding side Wall 11 is sprinkled with water from a tank 9, to which water is supplied automatically through a nozzle 8, as by a control valve 16 and a water-level responsive control means 17. Water runs over the top edge 10 of the tank 9 and down along the side wall 11 to the slot orifice 1. As shown in the drawing, the water level in the tank 5 is controlled by a float 15 connected to a level control means 19 operable to actuate a dump valve 18.
  • the substantially vertical flange 4 is provided with an adjustment means to permit variation in the slot opening.
  • the adjustment means may comprise brackets 4a, one being connected to the plate 12 and the other being connected to the splash plate 3, between which is sandwiched the flange 4.
  • the flange may be slotted as at 40 so as to permit in-plane displacement thereof simply by loosening and tightening a bolt and nut 4b.
  • Apparatus for removing paint particles and the like from ventilating air comprising a spray paint booth, said spray paint booth having an upstanding side wall and means for sprinkling water over the top of and down along the inwardly-facing surface of said side wall, said upstanding side wall curving inwardly of the booth at its lower end and terminating in a depending lip, a substantially horizontal plate underlying said side wall, an upstanding substantially vertical flange connected to said horizontal plate and vertically spaced from said lip to form a slot therebetween dimensioned to increase the velocity of the ventilating air as it is discharged through the slot, said increase being effective to eject and atomize Water flowing toward the slot, and a splash plate projecting inwardly of the booth from said flange and slot so that water, running down said side wall passes over said lip and impinges upon said splash plate.
  • Apparatus in accordance with claim 1 including adjustment means connecting said flange to said horizontal plate, said adjustment means adapted to permit said flange to be displaced towards and away from said lip to effect variations in slot opening.
  • Apparatus in accordance with claim 1 including a liquid tank underlying said horizontal plate and a baffle, depending from said horizontal plate, and extending into said liquid tank.
  • Apparatus according to claim 1 including a liquid tank underlying said horizontal plate, the liquid level in said tank being spaced below said horizontal plate, said splash plate being vertically spaced above said liquid level, and wherein further said vertical flange is laterally spaced from said lip outwardly of said booth to insure impingement of the water passing over the lip upon said splash plate inwardly of said flange.
