Two-stage-stirring high-speed mixing device for coating production

Abstract

The invention discloses a two-stage-stirring high-speed mixing device for coating production. The two-stage-stirring high-speed mixing device for the coating production comprises a stirring barrel, wherein a power mechanism is arranged at the top end of the stirring barrel; a stirring shaft of which the bottom stretches into the stirring barrel is in transmission connection with the transmission end of the power mechanism; a premixing mechanism separable from the stirring shaft is arranged at the upper end of the stirring shaft; a mixing transition mechanism is arranged below the premixing mechanism; the mixing transition mechanism is fixedly connected to the stirring shaft; the stirring shaft consists of an upper stirring part and a lower stirring part; the upper stirring part comprises at least one row of inclined stirrers; the lower stirring part is a spiral stirrer. The high-speed mixing stirrer is simple in structure and low in manufacturing cost, and achieves a synchronous premixing purpose; furthermore, in a rotary discharging mode, a material is more uniformly discharged, an radiation angle is more comprehensive, and the existence of a stirring dead corner is avoided; moreover, through adoption of the structure, the mixing time can be greatly shortened and the stirring efficiency is improved.

Description

technical field [0001] The invention relates to a high-speed mixing device for two-stage stirring paint production. Background technique [0002] Coating is a kind of material, which can be coated on the surface of objects by different construction techniques to form a continuous solid film with firm adhesion, certain strength, and coating belongs to fine chemical products. Modern coatings are gradually becoming a class of multi- Functional engineering materials are an important industry in the chemical industry and have been widely used in various industries. [0003] Coating production steps mainly include raw material pre-dispersion - grinding and dispersing - coating adjustment - filtration and packaging, etc., and the uniformity of coating mixing is the fundamental guarantee of coating quality. Most of the existing technologies are distributed according to the above steps, according to each Step down the processing time of coating can prolong, and the pre-dispersion mi...

Problems solved by technology

[0003] Coating production steps mainly include raw material pre-dispersion - grinding and dispersing - coating adjustment - filtering and packaging, etc., and the uniformity of coating mixing is the fundamental guarantee of coating quality. Most of the existing technologies are distributed according to the above steps, according to each Step down the processing time of coating can prolong, and the pre-dispersion mixing in the prior art is inhomogeneous, and its mixing and dispersing effect is poor; And because the paint is viscous, part of the paint will stick to the inner wall of the grinding and dispersing machine during the stirring process, resulting in waste of paint; again, the general stirring equipment mainly uses the high-speed stirring of the stirring shaft to complete, but the paint is in the production process. There are several kinds of raw materials, the quality of paint production is mainly reflected in the uniformity of raw material mixing, and the existing mixing and mixing equipment can not achieve the purpose of mixing several kinds of raw materials at the same time, but use one by one to add. Mixing, which will cause the mixing of raw materials to fail to achieve synchronization
