Abstract
The utility model discloses a coating recovery device which comprises a coating exhaust tank, a filter device, a drying device, a reaction tank and a collection tank which are connected with each other in sequence. The coating recovery device is characterized in that the filter device is a ceramic membrane separation device. According to the coating recovery device, coating in the coating exhaust tank is subjected to filtering and drying. Due to the fact that ceramic membrane has the advantages of high filter accuracy and good separation effect and the like in filtering, the filtered coating is high in purity. Then the filtered coating is subjected to solution, oil contamination elimination and leveling in the reaction tank, and pigments in coating slag are separated and wetted and rearranged. Consequently, the coating is recycled, and energy resources are saved, environment pollution is reduced, and the recycled coating is clear, high in purity, good in quality, can be directly used for recoating, and cost is saved.
Description
Technical field
The utility model relates to paint field, particularly a kind of recovering device for coating.
Background technology
In industrial production; most machinery, device all need to carry out spray treatment on its surface; play the protection breathe out to decorate about; spraying coating process generally is that through compressed-air actuated air-flow coating to be atomized into vaporific; and be coated onto under the drive of air-flow on the surface of coated article; to form coating, make body surface become smooth smooth, and painted a kind of application mode.Yet existing industrial coating disperses in the mist in the aerial spraying process large, and the coating loss is large, and utilization rate generally is no more than 50%, and the coating that does not use becomes the lacquer slag and becomes discarded object, and directly discharging had both caused environmental pollution, had caused the wasting of resources.
Coating material waste paint retracting device of the prior art, mainly comprise useless lacquer discharging pond, drying device filter, reaction tank, collecting pit etc., filter wherein mainly is to adopt filter bag to remove by filter the impurity such as silt, but filter bag only is coarse filtration, its filter effect is general, can not effectively remove small molecular weight impurity, coating purity and the quality of reuse are exerted a certain influence.
Summary of the invention
For the problems referred to above, the purpose of this utility model is to provide a kind of good filtration effect, coating to reclaim the high recovering device for coating of purity.
For achieving the above object, the technical scheme that the utility model proposes is: a kind of recovering device for coating, comprise the coating discharging pond, filter, drying device, reaction tank, the collecting pit that connect successively, it is characterized in that: described filter is ceramic membrane separation device.
Preferably, the preferred microfiltration ceramic membrane separator of described ceramic membrane separation device or ultrafiltration ceramic membrane separation device.
Preferably, the ceramic membrane separation aperture in the described microfiltration ceramic membrane separator is 0.01-0.5 μ m.
Preferably, the ceramic membrane separation aperture in the described ultrafiltration ceramic membrane separation device is 20～200nm.
Adopt technique scheme, recovering device for coating described in the utility model, by the coating in the coating discharging pond is filtered, drying, because it is high that ceramic membrane filter has a filtering accuracy, the advantages such as good separating effect, make the coating purity after the filtration high, then carry out dispersion moistening by reaction tank dissolving, degreasing, levelling and with pigment in the coating slag and rearrange, coating is recycled, reached energy savings, reduced environmental pollution, and the coating that reclaims is clean, purity is high, quality is good, can be directly used in again spraying, provides cost savings.
Description of drawings
Fig. 1 is recovering device for coating schematic diagram described in the utility model;
Wherein: 11. coating discharging pond, 12. ceramic membrane separation devices, 13. drying devices, 14. reaction tanks, 15. collecting pits.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
As shown in Figure 1, a kind of recovering device for coating comprises the coating discharging pond 11, ceramic membrane separation device 12, drying device 13, reaction tank 14, the collecting pit 15 that connect successively.Further, ceramic membrane separation device 12 preferred microfiltration ceramic membrane separator or ultrafiltration ceramic membrane separation devices, wherein the ceramic membrane separation aperture in the microfiltration ceramic membrane separator is 0.01-0.5 μ m, and the ceramic membrane separation aperture in the ultrafiltration ceramic membrane separation device is 20～200nm.
During concrete the use, coating in the coating discharging pond filters the impurity such as silt of removing in the coating by ceramic membrane separation device, because it is high that ceramic membrane separation device has a filtering accuracy, the advantages such as good separating effect, coating through ceramic membrane filter enters reaction tank, in reaction tank, drop into ethyl acetate, the organic solvent of ethyl acetate, carry out stirring and dissolving, and put into toluene isocyanide fat dehydrating agent, go out and also remain in moisture in the coating inside, adding the organosilicon oil resistance agent the oil stain decomposition in the useless coating, remove, add again the Siloxane-Oxyalkylene Copolymers levelling agent and carry out levelling, add at last polyamide and polyester pigment wetting dispersing agent and arrange auxiliary agent, useless coating is carried out dispersion moistening and rearrange, realize the recovery of useless painting color, obtain the coating that can reuse, can be directly used in again spraying, through reaction tank outlet, enter collecting pit, pack seal up for safekeeping for subsequent use.
Although specifically show and introduced the utility model in conjunction with preferred embodiment; but the those skilled in the art should be understood that; within not breaking away from the spirit and scope of the present utility model that appended claims limits; in the form and details the utility model is made a variety of changes, be protection domain of the present utility model.
