Description

Material mixing equipment

Technical field

The utility model is related to material mixing equipment technical field, more particularly to a kind of material mixing equipment.

Background technology

Currently, the type of container fixed mixing apparatus is relatively more, have helical-ribbon type mixing apparatus, plough coulter type mixing apparatus, Instantaneous weight loss particle mixing apparatus, planet conical mixing device.Wherein, horizontal mixing apparatus has horizontal ribbon mixing apparatus and plough Knife mixing apparatus etc., conical mixing device are divided into single-screw shaft cone-type mixer, double-spiral conical mixer, three by spiral number Three kinds of cone and screw mixer.

Conical twin-screw mixer is divided into as two kinds of symmetrical double worm mixer and asymmetric double mixing screw, it is symmetrical and Asymmetric spiral is all to make spiral while (being referred to as " rotation ") dynamic around the shaft rotation of oneself in mixing apparatus cylinder, goes back ring Around the central shaft of conical shell, and planetary motion is done again in cone near wall by means of the revolution of pivoted arm and (is referred to as " public Turn ").Conical twin-screw mixer whole equipment makes material generate compound motion in cone by the public affairs of spiral, rotation, to Reach mixed uniformly purpose.The direction of spiral rotation is so that it is positive direction that material is moved from cone base to cone top.It should Kind conical double ribbon rotation equipment mixing intensity is more violent, but plays the role of destroying surface layer to part powder material.

Taper three-screw mixer is that symmetrical double worm mixer adds a helical axis, entity spiral at medial axis position It is distributed in middle and lower part position.Intermediate conveyor screw to the level of double helix bottom, is then completed material lifting to cylinder by double helix The mixing of upper materials.The identical branch respectively of rotation direction of symmetrical two spirals turns to phase on the both sides of cylinder and with intermediate conveyor screw Instead, but three spirals are that material is carried from cone base to cone top.Taper three-screw mixer mixture homogeneity is not so good as Double worm mixer applies in general to the big equipment of mixing volume.

In addition, cone screw mixer also has, one is helical axis equipment.Along conical shell inner wall busbar branch one Helical axis, stirring theory and Gong, the structure of rotation are substantially identical with conical double ribbon rotation.

Above several conical mixing devices are verified by long-term use experience, conical twin-screw mixer mixing efficiency and The uniformity is all higher than three spirals, but three spirals just have certain advantage than double helix in big conical vessel, mainly The helical axis of symmetrical double helix is cantilever position and is to couple firmly between pivoted arm, is easy in the big material revolution of hybrid density Spiral fracture occurs, pivoted arm is also easy to happen the failures such as oil leak, and cone-type spiral axis mixing machine also has such general character, but compared to cone Shape double helix and the more low energy consumption of the required power of three spirals are also less, are also dropped to the surface damage degree of some special materials It is minimum.Also some materials can be easy agglomerate when being mixed, caking needs broken but cone-shaped device that cannot complete again.Closely In the past few years the type of material is intended to plus various, and density and material performance and hybrid technique are increasingly sophisticated, and there is an urgent need to a kind of energy The type of the cone screw mixer of compatible above several features and function occurs.
