A kind of dustless paint spraying room
Technical field the utility model relates to a kind of paint spray booth, especially a kind of dustless paint spraying room.
Background technology is last procedure of furniture processing in the japanning operation of furniture processing, also is the critical process that influences the furniture quality.General paint spray booth is common job shop now, and its part is provided with air exhauster, and the paint spray booth that has then is provided with the coating cloud that water curtain flies upward in order to filtration before air exhauster.This paint spray booth has very big drawback, coating cloud is irregular to be flown away, on furniture, be uneven distribution, have influence on coating quality, and most of paint still can be along with air be discharged, contaminated environment, the more important thing is that the dust in the paint spray booth can be deposited in furniture surface with paint, form the sand point, rework rate height, poor product quality.As a kind of improvement, utility model patent ZL00227521.x " furniture paint spray booth " discloses a kind of furniture paint spray booth, as shown in Figure 1, workplace 01 is connected with air intake passage 51 and air blast 52, this design that air blast 52 is preposition has formed certain normal pressure in workplace 01, make coating cloud sedimentation quickly, and can not fly upward everywhere, make spraying more even.And the air that enters workplace 01 is through purifying, for painting process provides a comparatively clean dustless environment.But because the air that process purifies is directly to enter workplace 01, there is the trend that is flowed by air inlet 02 diffusion in its air-flow instability, rather than the trend of formation perpendicular flow from top to bottom, makes coating cloud be uneven distribution, thereby influences product quality.
The summary of the invention the purpose of this utility model provides air-flow cleaning interior between a kind of spraying and is the dustless paint spraying room of vertical steady flow from top to bottom.
For addressing the above problem, the utility model comprises between spraying, pond and air exhaust passage, ground between spraying is located in described pond, pond one end is provided with the air exhaust passage that is partially immersed in the water, be provided with the depositing dust cascade in the described air exhaust passage, top, described dope room is provided with a static pressure wind storehouse of bringing wind system into; This bottom, static pressure wind storehouse is provided with separated air distribution plate between static pressure wind storehouse and spraying.Purify air enter the paint spraying room after, earlier in static pressure wind storehouse, after even the pressure, passes through the air distribution plate rectification again, thereby make the air-flow that enters between spraying very even, and wind direction is vertically downward.
Air inlet system of the present utility model can comprise air intake passage, air blast, air cleaner; Described air intake passage is connected on the static pressure wind storehouse, and its air outlet is located at static pressure wind storehouse center of top, after described air blast is located at the air intake passage inlet; Described air cleaner is located at the air intake passage porch, is made up of the primarily efficient filter wool and the inner wet curtain filter course of front end.Because the air outlet of air inlet system is located at static pressure wind storehouse center of top, make air-flow in static pressure wind storehouse by air outlet to around the trend of diffusion, its distribution is more even.
Can be provided with screen pack on the air distribution plate of the present utility model, this screen pack and air distribution plate be connected to plug-in.Because air distribution plate is provided with screen pack, make that the air that enters workplace is clean more, the plug-in design of screen pack makes that its replacing is convenient.
Static pressure wind of the present utility model storehouse can be a rectangle.Because static pressure wind storehouse is designed to rectangle, make the even pressure better effects if in static pressure wind storehouse.
As a kind of improvement of the present utility model, be coated with the grid of standing on the described pond for the user.Basin bottom is the inclined-plane that is tilted to discharge outlet, and the discharge outlet in described pond is communicated with water inlet by water circulation system, is provided with water purification installation in this water circulation system.
In sum, the utility model makes coating cloud vertically move downward under the promotion of static pressure wind storehouse air outlet air-flow for painting process provides a highly dustless environment simultaneously, and coating cloud is evenly distributed, and has saved paint when guaranteeing product quality; Secondly, the utility model has further reduced coating cloud because the possibility that the disturbance of air-flow is discharged from air exhaust passage has been protected environment.
Description of drawings is described in further detail the utility model below in conjunction with the drawings and specific embodiments:
Fig. 1 is the structural representation of existing patented technology;
Fig. 2 is a structural representation of the present utility model.
The specific embodiment as shown in Figure 1, the utility model comprises between spraying 1, pond 2 and air exhaust passage 21,1 ground between spraying is located in described pond 2, pond 2 one ends are provided with the air exhaust passage 21 that is partially immersed in the water, be provided with the depositing dust cascade in the described air exhaust passage 21,1 top, described dope room is provided with a static pressure wind storehouse 3 of bringing wind system 5 into; 3 ones are provided with 1 separated air distribution plate 4 between static pressure wind storehouse 3 and spraying at the bottom of this static pressure wind storehouse.Described air inlet system comprises air intake passage 51, air blast 52, air cleaner 53; Described air intake passage 51 is connected on the static pressure wind storehouse 3, and its air outlet 54 is located at static pressure wind storehouse 3 center of top, after described air blast 52 is located at air intake passage 51 inlets; Described air cleaner 53 is located at air intake passage 51 porch, is made up of the primarily efficient filter wool 531 and the inner wet curtain filter course 532 of front end.
Be coated with the grid 22 of standing between spraying on the pond 2 on 1 ground for the user, 2 bottoms, pond are the inclined-plane that is tilted to discharge outlet 23, the discharge outlet 23 in described pond 2 is communicated with water inlet 24 by water circulation system 6, is provided with water purification installation 7 in this water circulation system 6.
The utility model is in when work, and extraneous air filters the laggard static pressure wind storehouse 3 of going into through air inlet system 5 is preliminary, and even pressure the in static pressure wind storehouse 3 filtered and rectifications by air distribution plate 4 again, enters between spraying 1 with vertically downward direction.Air-flow is carried the coating cloud by shower nozzle ejection in top between pistol or spraying secretly, drops on furniture surface vertically downward, and remaining coating cloud falls into pond, ground 2.Water in the pond 2 is recycling by water circulation system 6.Air is discharged by air exhaust passage 21, and coating cloud is wherein stopped by water curtain and being detained, and falls into pond 2.
