Technical Field

[0001] The utility model relates to the technical field of water-based industrial paint, in particular to a filtering device for water-based industrial paint. Background Art

[0002] Water-based industrial paint mainly uses water as a diluent and does not require curing agents, thinners or some solvents. It is a new type of environmentally friendly anti-rust and anti-corrosion coating that is different from oil-based industrial paint. The application range of water-based industrial paint is extremely wide. It can be seen everywhere in bridges, steel structures, ships, electromechanical, steel, etc. It is energy-saving and environmentally friendly, and will not cause harm and pollution to the human body and the environment. Therefore, it is deeply welcomed by users. It is the future development direction of the coating industry and an alternative to oil-based paint. In order to ensure the film-forming effect of the paint film, the water-based industrial paint needs to be fully stirred to make its water-emulsion blend and filter it. For this reason, we propose a filtering device for water-based industrial paint.

[0003] A filtering device for water-based industrial paint is disclosed in Chinese patent CN202020890465.X. The filtering device for water-based industrial paint plays a buffering role through a buffer bin to prevent the filtrate from entering the suction pump body, thereby improving the safety of operation. However, the filtering device for water-based industrial paint only uses one layer of filter plate to filter the water-based industrial paint, which is prone to insufficient filtration.

[0014] Optionally, a feed inlet is provided on one side of the top of the water-based industrial paint filter bin, and the feed inlet is funnel-shaped.
