Description

Technical Field

[0001] The utility model relates to the field of stirring equipment, in particular to a stirring device. Background Art

[0002] As we all know, paint is a chemical mixture coating that can be firmly covered on the surface of an object for protection, decoration, marking and other special purposes. The book "Coating Technology", which is relatively authoritative in the Chinese coating industry, defines it as follows: "Coating is a material that can be applied to the surface of an object using different construction processes to form a solid film that is firmly adhered, has a certain strength and is continuous. The film formed in this way is generally called a coating film, also known as a paint film or coating." Paints are generally composed of four parts: film-forming substances, fillers (pigment fillers), solvents, and additives. The ingredients sometimes change slightly according to performance requirements. According to the classification of modern chemical products, paints belong to fine chemical products. Modern coatings are gradually becoming a type of multifunctional engineering materials and an important industry in the chemical industry. Paint dispersers are one of the components of paint production equipment and are efficient equipment for stirring, dispersing and dissolving paints. When dispersing paint, paint dispersers use a stirring device to stir the materials to mix, dissolve, disperse and refine them. It is found in the use of existing paint dispersers that the stirring devices of paint dispersers on the market can generally only rotate in one direction, so the dispersion of paint is very slow, which reduces work efficiency and leads to poor practicality.

[0003] Therefore, in view of the shortcomings of the prior art, it is necessary to design a stirring device to solve the above problems. Utility Model Content
