a spraying dust filtering device is communicated with a spraying chamber and comprises an air exhaust fan, a ventilating pipeline and a filtering bin, wherein the air exhaust fan is communicated with the filtering bin through the ventilating pipeline, and paint dust is discharged from the bottom of the spraying chamber through the air exhaust fan, enters the ventilating pipeline and enters the filtering bin for treatment;

the filter bin includes the air intake with air pipe intercommunication, be equipped with two sump of mutually independent in the filter bin, the air intake passes through three way connection and communicates two sump respectively, one of them sump of air intake alternative intercommunication, the bottom in sump is equipped with the delivery port, detachable is equipped with the filter screen directly over the delivery port.

The filter screen slope sets up in the sump, be equipped with the recoil device on the filter screen, the recoil device is including locating shower nozzle on the filter screen, the shower nozzle leads to pipe and draws water from the sump, be equipped with the dust on the lateral wall in sump and collect the passageway, the recoil device is followed the dust strikes on the filter screen in the dust collects the passageway, the storehouse is retrieved in the dust collection passageway intercommunication.

And an organic solvent for dissolving the dust is placed in the recovery bin.

The spraying dust filtering device further comprises a drying bin, a lime adsorption layer and an activated carbon adsorption layer are sequentially fixed in the drying bin, the drying bin is communicated with the two water bins through a pipeline, and a valve is arranged on the pipeline.

The spraying dust filtering device is provided with an air outlet, and the drying bin is communicated with the air outlet.

Compared with the prior art, the utility model discloses at first the dust is by one of them sump of air exhaust fan suction when using, at first through the water in the sump on precipitating the filter screen with the dust, again with in another sump of water suction for the water level reduces below the filter screen, and the dust is just on the filter screen this moment, and the dust that will stay on the filter screen through the shower nozzle of recoil device is recoil to fall into in the dust collection passageway and is retrieved the storehouse by organic solvent and dissolve, thereby can retrieve auxiliary agent wherein. The purpose of recycling is achieved.

Drawings

FIG. 1 is a schematic structural view of the present invention;

fig. 2 is a schematic structural view of the water sump of the present invention.

In the figure: 1. a spray chamber; 2. a water sump; 3. a valve; 4. a recovery bin; 5. a spray head; 6. filtering with a screen; 7. and (7) drying the bin.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that the embodiments or technical features described below can be arbitrarily combined to form a new embodiment without conflict.

As shown in fig. 1-2, the spraying dust filtering device is communicated with the spraying chamber 1 and comprises an air exhaust fan, a ventilating duct and a filtering bin, wherein the air exhaust fan is communicated with the filtering bin through the ventilating duct, and paint dust is discharged from the bottom of the spraying chamber 1 through the air exhaust fan and enters the ventilating duct to enter the filtering bin for treatment;
