Description

Technical Field

[0001] The utility model relates to the technical field of water-based aluminum-silver paste production, and more specifically, to a high-speed disperser for water-based aluminum-silver paste production. Background Art

[0002] Aluminum powder pigment has excellent gloss and hue and is one of the important metallic pigments. Due to the requirements for environmental protection, aluminum powder used in water-based systems, namely water-based aluminum paste, has been extensively studied. Water-based aluminum paste has unique environmentally friendly functions and can be widely used in water-based coatings and water-based inks. Water-based aluminum paste not only makes the film-forming material have the advantages of acid resistance, alkali resistance, and high temperature resistance, but also can be comparable to oily aluminum paste in terms of metallic gloss and hiding power. In the production process of water-based aluminum paste, a high-speed disperser is used to disperse and stir the water-based aluminum paste.

[0003] After searching, the utility model patent with Chinese patent number CN202321594775.7 discloses a high-speed disperser for the production of water-based aluminum-silver paste, including a bottom plate and two mounting support plates, the two mounting support plates are fixedly connected to the top surface of the bottom plate, a dispersion tank is fixedly installed between the upper parts of the two mounting support plates, and a hollow rotating rod is rotatably connected to the center of the inner top surface of the dispersion tank. When in use, the water-based aluminum-silver paste is stirred by the first stirring paddle and the second stirring paddle respectively, so that convection is generated inside the dispersion tank. At the same time, through the cooperation of the resistance ring and the sliding column, when the first stirring paddle and the second stirring paddle rotate, the sliding column slides on the wavy bottom surface of the resistance ring, thereby driving the first stirring paddle and the second stirring paddle to rotate and move downward at the same time, which can expand the stirring range of the first stirring paddle and the second stirring paddle, so that the water-based aluminum-silver paste is dispersed more fully.

[0004] Since the dispersion tank is internally connected with structures such as a resistance ring, when the structures connected with the first stirring blade and the second stirring blade fail, it is not convenient to remove the structures connected with the first stirring blade and the second stirring blade. In addition, aqueous aluminum silver will adhere to the inner wall of the dispersion tank and the outer wall of the resistance ring, which is not convenient for cleaning. When cleaning, the internal structure needs to be removed for cleaning. Since the structures connected with the first stirring blade and the second stirring blade have a certain weight, it is not convenient for people to extract the corresponding structures from the interior of the dispersion tank. Sometimes, it is necessary to use external equipment such as a crane to lift the structures connected with the first stirring blade and the second stirring blade from the interior of the dispersion tank, which makes it difficult to clean.
