CN201445934U - Diffusion mechanism of colloidal particles in silica colloidal solution - Google Patents

Abstract

The utility model discloses a diffusion mechanism of colloidal particles in a silica colloidal solution. A sheet material which is provided with a shaft sleeve above an axial direction is cut off a plurality of gaps along the circumferential side to form a plurality of blades, and the tail ends of adjacent blades are respectively twisted from the bases of the blades to the upward side and the downward side to form paddles and constitute paddle faces in different angles with longitudinal sections. The paddle faces form higher edges and lower edges, and the parts from the higher edges to the lower edges are extended outwards. Two areas with a diffusion function made at the upward side and the downward side are obtained, and at the same time the paddle faces are cut into the slope and use the higher edges as cutting faces to play a cutting role for the colloidal particles and generate a throwing role for the colloidal solutions and the colloidal particles to rotate the colloidal solutions and the colloidal particles to flow to a wall. The bases of the blades form negative pressure on the axial direction to cause the colloidal solutions and the colloidal particles of the upper part and the lower part to flow to the upper area with the diffusion function and the lower area with the diffusion function from the upper direction and the lower direction, and therefore the diffusion mechanism has a better diffusion effect and is beneficial for preparing a uniform and stable nano-silica colloidal solution.

Description

The diffusion mechanism of colloidal solid in a kind of dioxide/silica gel liquid solution

Technical field

The utility model belongs to a kind of diffusion mechanism, relates to the dispersion of colloidal solid in a kind of dioxide/silica gel liquid solution, more specifically, is the structural improvement of diffusion vane of this mechanism, with diffusion and the effect of improving colloidal solid.

Background technology

The aerosil nanometer grade powder has been applied to the gelatinizing agent as lead-acid accumulator.Because in transportation and storage process, this powder is assembled easily and formed bulky grain or become block, when being equipped to colloidal electrolyte, can't form homogeneous, stable status, need it is added and carry out processing in the entry, so that it fully spreads.

Usually, producer is that particle or block silica nanometer level powder carry out stirring at a high speed the employing diffusion mechanism to becoming, shearing makes it be reduced to nano level fine particle.At present, because its diffusion blade of this class diffusion mechanism oar faces that adopt a single angular distribution, thereby its shear efficiency is low, peptizaiton is little, the operating time is also longer, is difficult to reach producer's expected effect. more

The utility model content

The purpose of this utility model is to overcome above-mentioned deficiency and diffusion mechanism that colloidal solid in a kind of dioxide/silica gel liquid solution is provided, this mechanism improves the structure of diffuser vane, make it possess the blade that two groups of different levels are arranged, and to the turnover of two groups of blades The liquid flow pathConstruct, thereby improved the efficient of diffusion mechanism shearing and the effect of dispersion.

The purpose of this utility model is realized by following scheme:

The diffusion mechanism of colloidal solid in a kind of dioxide/silica gel liquid solution, be formed with the circular sheet material of axle sleeve by axial top, form several blades along its circumferential edge along cutting several breach, its main feature is, form blade from the base portion direction distortion up and down of blade respectively by the end of adjacent blades, described blade and having constituted becomes different angles with vertical section Oar Face, exist thus The oar faceFormed than high rim with than low edge, and stretched out to being rendered as than low edge than high rim.

Like this, on upper and lower direction, have one group that make progress, be interspersed OarLeaf, and one group downward, be interspersed OarLeaf, and each group OarIn the leaf each OarLeaf The oar faceConstitute different angles with vertical section, The oar faceFrom stretching out to presenting than low edge than high rim, therefore, can upwards form two zones at upper and lower during diffusion with diffusion, simultaneously, The oar face withAn inclined-plane incision, with The oar faceHigher edge is during as shear surface; not only can play the effect of shearing to colloidal solid on every side; simultaneously; colloidal solution and colloidal solid on every side also produced the effect of dishing out; make its turn and flow to chamber wall; and on blade base is axial, formed negative pressure; make the colloidal solution of upper and lower part and colloidal solid respectively constantly from upper and lower to flowing to upper and lower peptizaiton zone; thereby can obtain better diffusion effect, help making homogeneous, stabilized nano dioxide/silica gel liquid solution.

In the such scheme, identical, the described blade size of described breach size is also identical.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is carried out concrete detailed description:

With reference to Fig. 1, Fig. 2 and Fig. 3, this diffusion mechanism, above it is axial, form axle sleeve 12 by circular sheet material 1, circular sheet material 1 cuts ten equal-sized breach 15 equably along its circumferential edge edge, and form ten blades 13 that size is identical, the end of adjacent blades 13 is respectively from the direction distortion up and down of the base portion 14 of blade, forms one group of upwards distortion OarLeaf 13a and one group of distortion downwards OarLeaf 13b, OarLeaf 13a and OarLeaf 13b replaces mutually, and makes OarBetween the leaf 13a or OarStagger mutually between the leaf 13b, make upper and lower therefrom OarThe leaf group OarLeaf all is evenly distributed, OarLeaf 13a and OarThe lateral surface of leaf 13b is the inclined-plane, can be used as oar face 13c, the outermost edges of the projection of oar face 13c on blade base 14 horizontal planes becomes different angles with the longitudinal section, and be rendered as orderly variation gradually, formed than high rim (or dark edge) 13d with than low edge (or more shallow edge) 13e at oar face 13c thus, and stretch out to being rendered as than high rim 13d, by than the shear surface of high rim (or dark edge) 13d as diffusion mechanism than the line of low edge 13e.

Like this, when diffusion mechanism is rotated by axle sleeve 12 drivings by the rotating shaft of high-speed electric expreess locomotive, on OarUnder the Ye Zuhe OarYe Zuhui to forming upper and lower diffusion zone, and shears colloidal solid by the shear surface that constitutes than high rim (or dark edge) 13d at the upper and lower of blade base 14, simultaneously, by The oar face13c is and obliquely makes circular motion, colloidal solution and colloidal solid are thrown to chamber wall, and blade base axial formed negative pressure up and down, make the colloidal solution of upper and lower part and colloidal solid respectively constantly from upper and lower to flowing to upper and lower peptizaiton regional center for further shearing and disperseing.
