Description

Vertical five-layer helical ribbon impeller reactor with inner barrel

Technical Field

The utility model belongs to the technical field of the reactor, concretely relates to vertical five layers of helical ribbon impeller reactors who possesses the inner tube.

Background

The reactor is a device for realizing the reaction process and is widely applied to industrial departments of chemical industry, oil refining, metallurgy, light industry and the like. Reactors are classified into homogeneous reactors and heterogeneous reactors according to the phase state of the reaction mixture in the reactor. The reaction between solid material and other material occurs mainly in the contact surface of solid material particle surface, so that the equipment has strong shearing, crushing, stirring and mixing functions, and the solid material is crushed to increase surface area and dispersed homogeneously in liquid material for smooth reaction.

The reactors currently used for liquid-solid phase materials are mainly anchor stirred reactors, double helical conical mixers, horizontal ribbon mixers, kneaders (horizontal double-shaft mixers).

The anchor type stirring reactor is provided with a stirrer which is in a shape similar to a ship anchor, can be used for mixing reaction of granular materials and powdery materials, but has poor shearing and crushing functions and is not suitable for high-viscosity materials and reaction of high-viscosity pasty products generated in the reaction process;

the double-helix conical mixer is obliquely provided with a pair of long and short helices along the inner wall of the conical barrel, the helices respectively rotate by taking the helical central line as the axis, and simultaneously, the helices circularly move by taking the central line of the conical barrel as the axis, so that the materials in the conical barrel are mixed, the mixing speed of granular and powdery materials is high, the mixing quality is uniform, but the shearing and crushing functions are poor, and the double-helix conical mixer is not suitable for high-viscosity materials and the reaction of high-viscosity products generated in the reaction process, and is also not suitable for the reaction of solid products generated by the crushing reaction;

the horizontal helical ribbon mixer has one driving shaft with two layers of helical ribbons, one positive helical ribbon and one negative helical ribbon, and the equipment has the inner helical ribbon and the outer helical ribbon driven by the same driving shaft to rotate in the same direction. The mixer has the advantages of high mixing speed, high uniformity, bearing at two ends of the mixer, difficult material entering and low maintenance rate. But is not suitable for the reaction of high-viscosity materials and high-viscosity products generated in the reaction process, and is also not suitable for the reaction of solid products generated by the reaction needing to be crushed;

the kneader is a kind of horizontal mixer, and is a device which uses a pair of impellers (usually Z-shaped) which are matched and rotated to produce strong shearing action, so that the semi-dry or medium-high viscosity material can be uniformly mixed, stirred, mixed, kneaded, broken and dispersed into various chemical products. However, when the reaction produces a medium-high viscosity paste product, the impeller is wrapped by the adhered paste, the adhered paste rotates together with the impeller, the mixing effect of the materials is lost, the mixing of the materials is insufficient, and the reaction of the materials is insufficient.

In summary, the above-mentioned several mixing reaction devices commonly used at present have advantages and disadvantages, and are suitable for mixing reaction conditions of certain materials, not suitable for reaction of paste with medium-high viscosity generated in the reaction process, and not suitable for reaction of solid generated in the reaction process needing to be crushed, so that it is necessary to develop a mixing reactor with high shearing property, high mixing property, high crushing property, and stronger adaptability.
