Abstract

The utility model relates to a roller device which is mainly used for the continuous mixing of a plurality of low-intensity granule matching materials. The utility model solves the problems of continuous type material mixing equipment that the breaking of low-intensity granule materials is large, the mixing of the low-intensity granule materials is nonuniform when output is large, the structure of the equipment is complex, etc. A column-shaped hollow cavity is composed of two cylinder bodies in a coaxial way, the diameters of the two cylinder bodies are different in size, the cross section of the column-shaped hollow cavity is a circular ring, one pair to random pairs of helical blades with opposite angles of lead are axially arranged in the column-shaped hollow cavity to form continuous V-shaped helical blades, and the circumferential direction of the circular ring column-shaped hollow cavity is provided with two to thirty strips of V-shaped helical blades which are in the same shape and are parallel to each other. After the materials enter the roller device, the materials are divided into small material quantity by two to thirty separate flow passages which are composed of the V-shaped helical blades and mixed, and the mixing rate is high.

Description

Drum apparatus with V-type helical blade

The utility model relates to a kind of multiple powdery of low-intensity, particle cooperation material drum apparatus of mixing continuously that is used for.

In order to make multiple different powdery or particle cooperate material under continuous state, evenly to mix, just must adopt the continous way mixer, in the prior art there be the continuous mixer primary structure:

(1) mixing screw.By static cylindrical shell be in that rotating shaft in it is provided with related type or paddle type blade constitutes, be divided into vertical and horizontal (horizontal single shaft and twin shaft etc. in addition) according to the location means of rotating shaft.This structure is when mixing of materials, and material is under the effect of helical axis, and based on whole rectilinear motion, so the blending of different material boudary portion is more remarkable, but the mutual blending of the particle between the different material centre is very difficult.Combined amount in unit interval is big more, and evenly mixing is difficult more, and this mixer generally is not suitable for, and granule strength is low not to allow to make in mixing the mixing of materials of particle destruction to use again.

(2) high speed rotating disk type mixer.Central authorities are provided with plectane and the support plate of doing rotation at a high speed in casing, and material is imposed strong centrifugal force, and the state that it will make material can be in single particle mixes, so mix comparatively desirable.But because in mixing, the mechanical force that particulate material is subjected to is bigger, so be not suitable for the mixing of low-intensity particulate material.

(3) continuous V-Mixer (as accompanying drawing 1).Material is axial flow in machine, and in flowing blending effect is fully arranged, and little and cylindrical shell V-type bending mixes comparatively desirable more for a long time when combined amount.The external force that material particles is subjected in the work is little, is fit to the mixing of low-intensity particulate material.But because this device structure complexity, thereby the manufacturing process trouble, cost height, and the bending of cylindrical shell V-type can not be more so mix when output is big in the unit interval badly, uses less at present.

At the problems referred to above, the purpose of this utility model is to provide the multiple granule materials of a kind of suitable low-intensity to mix continuously, and produces the drum apparatus with V-type helical blade great, simple and compact for structure, easy to manufacture, that cost is low in the unit interval.

The scheme that solves above-mentioned task is to adopt following structure: this drum apparatus by inner barrel, outer cylinder body, rise helical blade, fall helical blade and form.The axial inner surface of the axial external surface of inner barrel and outer cylinder body is 360 ° the taper or the rectangle surfaces of revolution, and inner barrel places outer cylinder body interior and coaxial, it is the cylindrical cavity of annulus that two cylindrical shells constitute section, be provided with vertically within it by 1 to arbitrarily to have an opposite helical lift angle each other adjacent rise helical blade and fall helical blade constitute continuous V-type helical blade, the both sides of V-type helical blade width are respectively with interior, outside the outer cylinder body, the inwall card closes, the summit of V-type helical blade two sides angle is respectively on two buses of inner barrel outer wall, the circumferencial direction of annulus cylindrical cavity, be provided with the V-type helical blade that 2 to 30 strips are identical and be parallel to each other, the V-type helical blade with in, the card place of closing of outer cylinder body adopts all or part of fixedly connected.

The runner that cooperates material to constitute each other to the V-type flight that infeeds by the circumferencial direction setting when multiple powdery or particle from the importer of cylinder, cylinder is so that helical blade produces the direction rotation of downslide effect to material, cooperate material just in the runner that the V-type helical blade constitutes each other, constantly carry out before and after, up and down, do axial flow in the inside and outside blending, the material that mixes flows out from outlet continuously.Because at circumferencial direction, be provided with 2 to 30 V-type helical blades,, make the cooperation material that infeeds be divided into 2 to 30 parts like this so constituted 2 to 30 separate V-type helical flow paths, carry out the blending of small powder amount, and the external force that material is subjected in the mixed process is very little.This drum apparatus also can be used for moist powdered, granule materials are carried out drying when feeding hot gas.According to different instructions for uses, device can adopt metal, nonmetal or metal and the manufacturing of nonmetal complex solid material.

Drum apparatus with V-type helical blade of the present invention, simple and compact for structure, easy to manufacture, cost is low.Be fit to low-intensity powdery or multiple granule materials and mix continuously, realize the small powder amount mixing of independent multithread road, mixing efficiency can improve nearly one times.In addition, this device also can be used for the drying to moist powdered or granule materials.
