Description

A multi-purpose mixer with multi-shaft variable pitch

technical field

The utility model relates to a mixer, in particular to a multi-purpose mixer with multiple shafts and variable distances.

Background technique

Generally, the mixers used in the industrial field have a single-shaft stirring structure. The blades of this single-shaft stirring structure can only rotate in one direction during work. The speed of the outer ring of the stirring blade is high, and the speed of the inner ring is low. It is easy to make circular motion in one direction along the blades, and the distance between the blades of each layer is fixed, so it can only meet the basic stirring effect. In some places that require high stirring quality, fast stirring speed and high output Occasionally, its stirring and mixing effect is difficult to meet the requirements, and further improvement is needed.

The mixer is mainly used to stir and mix various materials to make the materials evenly mixed. When the mixing arm and mixing blade of the mixer come into contact with the mixture, it will cause wear. The existing stirring arms are generally made of Q235A, 45 steel, 40Cr, cast steel and other materials. Q235A is cheap but has poor wear resistance. 45 steel and 40Cr have good mechanical properties and are easy to process, but expensive. The production process of cast steel Simple, suitable for mass production, low manufacturing cost, but easy to break; the existing mixing blades are generally made of A3 steel plate, manganese steel plate, Hardox steel plate, high chromium cast iron, polymer plastic, spraying materials and surfacing materials and other materials , A3 steel plate is cheap but poor wear resistance, manganese steel plate, Hardox steel plate, high chromium cast iron, polymer plastic and other materials have good mechanical properties, easy processing, but expensive. Although the wear of mixing blades and stirring arms is inevitable, cannot be eradicated, and can only be improved, how to develop a wear-resistant and low-cost mixing blade and stirring arm for the use function of the mixer, and improve the performance of the mixing blade and stirring arm The service life and the reduction of production cost are the problems to be solved in the mixing industry.
