Specific embodiment

The present invention will be further described with reference to the accompanying drawing.

As shown in Figs 1-4, the blender of the utility model, including agitating shaft 1 and stirring blade 2, edge on the agitating shaft 1 At least two rows of stirring blades 2 are axially provided with, position is staggered in the circumferential for each row's stirring blade 2, and looks up and stir from axis Stirring blade 2 all on axis 1 is mixed to be uniformly distributed circumferentially.

When the blender is applied to the horizontal mixer that solid-liquid mixes, 1 lateral arrangement of agitating shaft, part on blender Expose liquid level, in blender rotary course, stirring blade 2 can generate interaction with liquid level when rotating into liquid level, All stirring blades 2 are uniformly distributed circumferentially, that is to say, that and all stirring blades 2 are respectively positioned on the different angle in circumferential direction, Therefore, different from the case where having multiple paddle slap liquid levels simultaneously in the prior art, while an only stirring blade 2 Liquid level is flopped, the spray of generation and suffered resistance all can substantially reduce, while the time interval for flopping liquid level reduces.Instantaneous resistance Power reduces, and the frequency that resistance generates increases, and the stability of blender operation can be improved with this, and extend driving mechanism uses the longevity Life.Other than the utilization of this situation, the case where a certain angle will receive biggish transient drag is turned to all for stirring blade 2 It can use.

Every row's stirring blade 2 can set up multiple stirring blades 2 separately as in the prior art in the circumferential, can also every row only One row's stirring blade 2 is set, and runs the inner end portion overlapping of the stirring blade 2 of adjacent row.Stirring blade 2 can be using straight Paddle structure, curved impeller structure, oblique paddle structure, vane structure etc., must since solid-to-liquid ratio is great for solid-liquid mixing Radial be stirred need be increased, wherein the radial mixed of straight paddle structure and curved impeller structure is most strong, and most preferably selects curved leaf The bending direction of structure, stirring blade 2 is consistent with the steering of agitating shaft 1, can pick up and be sunken to bottom solid material, be raised It is sufficiently mixed with liquid, while interaction force of curved impeller structure while with very strong radial stirring capacity, with liquid level It is smaller, it is possible to reduce to enter the resistance during liquid, and reduce the spray.

In contrast the resistance of its suffered liquid is just very strong, to reduce the interaction force of stirring blade 2 and liquid and adding The ability of strong hybrid solid is uniformly provided with material spilling hole 21 on stirring blade 2, makes stirring blade 2 during rotating down, portion Liquid separation body is flowed through by material spilling hole 21, and then reduces the interaction force of itself and stirring blade 2, and reduces the rotation of stirring blade 2 The spray generated when liquid level out, while during rotation raises solid material to stirring blade 2 upwards, solid material is gradually from leakage Expect that hole 21 leaks out, more uniformly is scattered in liquid, to strengthen compounding effect.The size of material spilling hole 21 is by solid material Size and its form depending on, while guaranteeing that it is enough to raise enough solid materials, solid material can be preferably from material leakage Hole 21 gradually leaks out.

But the blade construction that radial direction stirring capacity is strong, axis mixed are axial mixed in order to balance with regard to relatively weak It closes and is mixed with radial, stirring ribbon 3 is provided on the agitating shaft 1,2 inner end of stirring blade is connected on agitating shaft 1, stirs The two sides for mixing the outer end of blade 2 are connected on stirring ribbon 3, at this point, the inner end of practical adjacent stirring blade 2 is to partly overlap 's.Stirring ribbon 3 has very strong axial backmixing ability, and is arranged such and will not conflict with 2 phase of stirring blade, to make to stir It mixes device and has both very strong axially and radially mixed.If one section of ribbon, which is only arranged, will cause side heap of the solid material to container Product, therefore, the stirring ribbon 3 include the first ribbon section 31 and the second ribbon section 32, the first ribbon section 31 and the second spiral shell The hand of spiral with section 32 on the contrary, can improve the uniformity of mixing by the effect of this two sections of ribbons to a greater extent.
