Description

Technical Field

[0001] The utility model relates to the technical field of paint recovery, and specifically, to a water-based paint solvent separation and recovery mechanism. Background Art

[0002] Water-based paint is a paint that uses water as a solvent or a dispersion medium. It is a relatively new type of paint in the paint market. Water-based paint includes water-soluble paint, water-dilutable paint, and water-dispersible paint. During the use of water-based paint, some external impurities are likely to fall into the paint. In order to avoid waste of unused paint, a paint recovery device is often used to recycle the paint.

[0003] After investigation, a water-based paint solvent separation and recovery mechanism disclosed in the publication number: CN217409946U. This technology discloses that "it includes a base, the top of the base is fixedly connected with a filter box, the bottom of the filter box is communicated with a discharge pipe, two mounting sleeves are fixedly connected inside the filter box, and filter plates are assembled in both of the two mounting sleeves. The top of the filter box is fixedly connected with a discharge box, and a feeding hopper is fixedly connected to the top of the discharge box. A conduit is installed on the inner side wall of the top of the filter box, and the top port of the conduit is communicated with the discharge box. The bottom end of the conduit is communicated with an annular frame, and a plurality of through holes are opened on the outer side surface of the annular frame. A stirring component is arranged inside the discharge box, so that the water-based paint can be filtered for impurities twice, which effectively improves the purity of the water-based paint. At the same time, the water-based paint can be evenly sprayed onto the filter plate, that is, the water-based paint can be filtered more completely and thoroughly."

[0004] However, the above-mentioned water-based paint solvent separation and recovery mechanism has the following disadvantages:

[0005] 1. Although the recovery mechanism in this patent can filter the water-based paint more completely and thoroughly during use, during filtration, some impurities in the paint will remain on the filter plate in the filter box, which is difficult to clean.

[0006] To solve the above problems, a water-based paint solvent separation and recovery mechanism is proposed in this application. Content of the Utility Model
