Description
Technical Field
The invention belongs to the field of coating production equipment, and particularly relates to a special stirring dispersion machine for coating production.
Background
The dispersion machine, the generalized is a kind of mixer, owing to adopt high speed mixer (like circular saw tooth type agitator) can form stronger turbulent flow in the part, has stronger dispersion emulsification effect to the material usually, so also be called the dispersion machine to this kind of high speed mixer, the dispersion machine mainly divide into over-and-under type dispersion machine and dispersion machine for the cauldron, over-and-under type dispersion machine can divide into hydraulic pressure lift dispersion machine, pneumatic lift dispersion machine, hand lift dispersion machine etc. again according to the lift mode.
The paint consists of resin base material (liquid), pigment and filler (solid), solvent (liquid) and assistant, and the pigment and filler are required to be uniformly dispersed in the resin base material to form liquid paint slurry in production. The production process of the paint refers to a material transfer or conversion process for processing raw materials and semi-finished products into finished colored paint products, wherein the stirring and dispersing process is a process of mixing various raw materials, dispersing various components such as pigments, fillers and the like to the corresponding required fineness through shearing force, and uniformly dispersing the components in the whole medium. Therefore, a key device in paint production is the disperser device.
In recent years, stirring disperser equipment for paint production does not change much in aspects of stirring mode, structure optimization design and the like, and along with the improvement of labor cost, the increase of diversified small-batch production requirements of paint users and the appearance of customized products, the following defects of the existing stirring disperser for paint production become more and more obvious:
1. the shearing and dispersing effect on the coating is poor, and the production efficiency is low. The production time required by qualified products is too long to meet the requirements of customers for small-batch rapid supply, and the time cost and the labor cost are high.
2. When different types of coatings are switched to produce, the cleaning difficulty is high, and the safety is poor. Because the residual paint is manually cleaned in the stirring tank by manpower, the paint cannot be quickly and thoroughly cleaned, and the paint is easy to stick. Therefore, the cleaning efficiency is low, the effective production time is greatly reduced, and the labor cost is high.
The fundamental reason for the above problems is that the design of the working principle of stirring dispersion is not ideal, and the fixing mode of the stirring mechanism in the dispersion machine has defects. Most of the existing dispersion machines adopt a dispersion disc or outer layer spiral stirring design structure, the formed shearing force is limited or the acting shearing area is limited, the shearing force is mainly concentrated in a local area, and the integral three-dimensional circulation effect is lacked or even not existed. The stirring mechanism is fixedly connected to the base in an inseparable mode or adopts a heavy single-arm hydraulic lifting mode, so that the dispersing machine cannot be conveniently lifted to a safe operation space during cleaning. The stirring parts are not thoroughly cleaned, the stirring parts can be adhered to the coating after long-time operation, and the stirring efficiency and the product quality are reduced.
The market needs a new special stirring dispersion machine for paint production, which can overcome the defects.
