Description

Technical Field

[0001] The utility model relates to the technical field of water-based paint processing, in particular to a device that is beneficial to vacuum suction of water-based paint. Background Art

[0002] Water-based paints use water as a solvent or dispersion medium. They are a relatively new type of coating on the market and include three types: water-soluble paints, water-reducible paints, and water-dispersible paints (latex paints). Water-based paints use water-soluble resins as their film-forming agents. Post-emulsification emulsions are coatings formulated with a film-forming agent. Solvent-based resins are dissolved in an organic solvent, then dispersed in water with the help of an emulsifier through vigorous mechanical agitation to form an emulsion. This resulting paint can be diluted with water during application. An emulsion is a dispersion of small particles formed by the polymerization of unsaturated vinyl monomers under specific temperature conditions in the presence of an emulsifier and mechanical agitation. After stirring, a layer of bubbles forms on the surface of the emulsion. If these bubbles are not extracted, they can enter the next process, affecting quality. Therefore, we have developed a device that facilitates vacuum aspiration of water-based paints. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] like Figure 1-4 As shown, this embodiment provides a device that is conducive to vacuum suction of water-based paint, including a storage tank 1, a collection tank 3, a suction mechanism 4 and a hanging sensor 5.

[0027] The storage tank 1 is constructed of stainless steel, with a feed pipe 101 at the top and a discharge port 103 at the bottom. Both the feed pipe 101 and the discharge port 103 are equipped with valves. Multiple support legs 102 are located on the outside of the bottom to securely support the tank. A motor-driven agitator 2 is located inside the tank 1, stirring the material horizontally. The agitator 2 can be implemented using a variety of conventional agitation components. A spiral agitator blade is most commonly used, but a rotating shaft-driven disc can also be used.

[0028] The collecting tank 3 has two sides with chutes 31, in which a slider 32 is slidably provided. A restoring spring 34 is installed between the bottom of the slider 32 and the chute 31. The outside of the slider 32 is fixedly connected to a filter screen 33. The adsorbed foam is filtered and collected by the filter screen 33.

[0029] The suction mechanism 4 includes a main sleeve 42, a secondary sleeve 43, a vacuum pump 44, a suction nozzle 45, and a suction pipe 441; the main sleeve 42 is fixed to the outside of the top of the storage tank 1, the secondary sleeve 43 is telescopically sleeved on one end of the main sleeve 42, and the other end of the secondary sleeve 43 extends into the storage tank 1; the vacuum pump 44 is fixed on the secondary sleeve 43, and the outlet of the suction nozzle 45 is connected to the vacuum pump 44; one end of the suction pipe 441 is connected to the outlet of the vacuum pump 44, and the other end is connected to the collection tank 3.

[0030] The suspended sensing component 5 is suspended on the top wall of the storage tank 1.
