Abstract

The utility model relates to a recovering and purifying device for spraying paint, which is composed of a recycle chamber, an air conduct, an air extractor, a liquid box, a water tank, etc. The recycle chamber is a five surfaces sealed operating room with a working table at the bottom to place waiting painted component and a driving device to make the recycle chamber rotating, the top of the recycle chamber is provided with a spraying pipe, and the sprayed liquid absorbs paint mist. The gas in the recycle chamber is exhausted through the air conduct, and the air conduct is provided with a liquid spraying pipe and a water spraying pipe to spray two layers of oil curtain and water screen and further absorb oil mist. In this way, the environment of the paint working field is largely improved, meanwhile, the used liquor can recycle the paint to reuse in order to largely save paint resource.

Description

Recovering and purifying device for spraying paint

The utility model relates to recovery technology and the device that sprays paint.

In the work of spraying paint, destatic spray paint outside, all can there be a large amount of paint fogs the work-yard, the aerial paint fog of this disperse, not only lost a large amount of paint resources, the paint utilization rate is reduced greatly, simultaneously also serious pollution working environment worsens workman's operating condition, so need the reclaiming clean device.Chinese patent 88208932.3 utility model patents, name is called " oil wash formula coating cloud clean room ", discloses a kind of paint mist purifying means.The mist of oil that this patent mainly utilizes oil pouring plate absorption to float is with near the mist of oil the minimizing place of working.But can not reclaim paint utilizes again.

The purpose of this utility model is that a kind of can the recovery of design flies when spraying paint mist of oil that escapes and the reclaiming clean device that sprays paint of getting rid of pernicious gas.

Reclaiming clean device of the present utility model is made up of several parts such as reclaiming chamber, ventilation shaft, air exhauster, liquor box, water tank, said recovery chamber is the operating room of First Five-Year Plan face closure, be provided with workbench in the bottom, place workpiece to be sprayed paint thereon, workbench can be driven by transmission mechanism and do gyration.Be provided with sparge pipe with holes at recovery top, chamber along three sidewalls, can spray the solution that can dissolve paint in the sparge pipe, the solution that is sprayed flows down along three sidewalls, flow to after paint fog is absorbed and reclaims the bottom, chamber, and the outage stream liquid feeding tank by the bottom recycles.Have a ventilating opening on a sidewall that reclaims the chamber, this ventilating opening and ventilation shaft join.The ventilation shaft other end links to each other with air exhauster, and air exhauster is extracted out by ventilation shaft reclaiming indoor gas.Air inlet one end of ventilation shaft is provided with a sparge pipe at the pipeline top, and this sparge pipe sprays solution downwards and becomes a liquid curtain, will absorb and outage by the bottom advances liquid feeding tank and recycles by the remaining mist of oil in the gas of ventilation shaft.For further removing the mist of oil in the gas, establish a sparge pipe at the port of export top of ventilation shaft, the ejection current form a cascade, and this cascade can be taken away the mist of oil of small amount of residual in the gas, flows into water tank by osculum and recycles.For avoiding liquid in the ventilation shaft, water to mix, can establish a baffle plate in the centre.Outage links to each other with liquid case and water tank respectively with osculum.

Adopt reclaiming clean device of the present utility model to adsorb the absorption of a recovery and a cascade through second aqueous because of the gas of band mist of oil, so can remove a large amount of showy mist of oils, recycle because of solution system simultaneously, when the paint content in the solution is higher, can reclaim use, save a large amount of paint resources.Extract out by air exhauster because of the gas in the operating room again,, improved working environment greatly so air can not polluted by paint aerosol and pernicious gas near the work-yard.

Illustrate that accompanying drawing is as follows:

Fig. 1 is the utility model reclaiming clean device schematic diagram.

Fig. 2 is sparge pipe of the present utility model (15, a 16) structural representation.

The course of work and the embodiment of accompanying drawings the utility model reclaiming clean device are as follows: the recovery chamber (1) of reclaiming clean device, by sidewall (2,3), rear wall (4), top board (5), base plate (6) is formed, and is provided with workbench (7) in the bottom of reclaiming chamber (1), and has axle (8) to drive its revolution by transmission mechanism (9).On workbench (7), can place workpiece to be sprayed paint (10).Along two sidewalls (2,3) and rear wall (4) sparge pipe (11) is set at the top of reclaiming chamber (1), sparge pipe (11) has spray hole (12), can spray solution, and solution can be solvent or diluent, has outage (13) on base plate (6).On a sidewall that reclaims the chamber, have ventilating opening, this ventilating opening and ventilation shaft (14) join, roof at ventilation shaft (14) is provided with sparge pipe (15) and sparge pipe (16), and this two pipe can spray two-layer liquid curtain (structure of pipe is seen Fig. 2), with the mist of oil in the adsorbed gas.Be provided with baffle plate (17) and outage (18) in the bottom of ventilation shaft (14), osculum (19).Liquid case (20) has drain pipe (21) to link to each other with sparge pipe (11,15), and oil return pipe (22) is continuous with outage (13,18), in liquid case bottom tapping valve (23) is arranged.Water tank (24) has outlet pipe (25) to link to each other with sparge pipe (16), and return pipe (26) links to each other with osculum (19).Be provided with Draw off valve (27) at water tank bottom.

Reclaiming clean device of the present utility model use is as follows: workpiece to be sprayed paint (10) is placed on the workbench (7), and workbench (7) can turn round, and makes workpiece can spray paint all around.When the solution of sparge pipe (11) ejection when the sidewall that reclaims the chamber flows down, will float aerial mist of oil absorption dissolving and band down, flow to liquid case (20) by outage (13) and recycle.The gas that reclaims in the chamber (1) is discharged through ventilation shaft (14).Entrance point at ventilation shaft (14) has a sparge pipe (15), so this Guan Weiyi has the bend pipe (see figure 2) of seam can spray the liquid curtain, gas by the liquid curtain after its with mist of oil be adsorbed dissolving again.The port of export at ventilation shaft has a sparge pipe (16), and the structure of this pipe is the same with sparge pipe (15), can spray cascade, the further mist of oil in the adsorbed gas, and mist of oil significantly reduces in the gas of discharge so can make.
