Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of chemical equipment, especially to a water-based passivation solution storage tank with combined proportioning structure. BACKGROUND

[0002] Traditional passivation solution storage tanks are usually single tank body structures, and when configuring passivation solution, various components need to be added to the tank body in proportion manually. With the increasing strictness of environmental protection regulations, the use of water-based passivation solution is paid more and more attention. Water-based passivation solution has the advantages of low toxicity and low pollution compared with traditional chemical passivation solution. However, the components of water-based passivation solution are more complex, and the requirements for storage and proportioning are higher.

[0003] Any paint using water as a solvent or dispersion medium can be called water-based paint. Water-soluble paint uses water-soluble resin as a film-forming material, with polyvinyl alcohol and its various modified materials as representatives. In addition, there are water-soluble alkyd resin, water-soluble epoxy resin, and inorganic polymer water-based resin. Water-based paint includes water-soluble paint, water-dilutable paint, and water-dispersible paint. Water-soluble paint uses water-soluble resin as a film-forming material, with polyvinyl alcohol and its various modified materials as representatives. In addition, there are water-soluble alkyd resin, water-soluble epoxy resin, and inorganic polymer water-based resin. The storage tank has a liquid level display function. A transparent display window is provided on the side of the storage tank body. However, due to the viscosity of water-based paint, the liquid level position is difficult to display through the display window.

[0004] The existing patent (publication number: CN216917178U) is a storage tank with liquid level display function for colored water-based paint. By setting an indicating float in the storage tank body, it can float at the liquid level position using its own buoyancy, and the sliding part is used to indicate the remaining amount of water-based paint in the storage tank body, avoiding unclear display of the remaining amount due to the characteristics of water-based paint.

The existing water-based passivation solution storage tank is usually directly delivered into the main tank during proportioning. However, the liquid flow rate and impact force of different raw materials are different, which can cause splashing, resulting in local high concentration or incomplete mixing during subsequent mixing. Moreover, it is not convenient to fully mix different raw materials, leading to stratification or local component enrichment on the liquid surface.
