Description
Technical field
The present invention relates to a kind of stirring and apparatus for distributing, the stirring and the uniform distribution of material in be specially adapted to ferment tank body or the container.
Background technology
Be used widely at industrial circle fermentation tank body or tun at present, after material drops into tank body or container, owing to the material density reason can produce natural layering, in general be respectively from top to bottom: scum layer, supernatant layer, active layer and sediment layer.Research shows that the more vigorous zone of microbial activities often concentrates on active layer after the layering, and microorganism lacks or the movable situation of unsuitable growth of microorganism and other each layer meetings occur.Simultaneously, material layering also causes conducting heat uneven, makes that the interior temperature of tank body or container is inconsistent, and then influences engineering effort.Based on above situation, the most of mode that adds stirring that adopts of existing fermentation tank or container, most common form is to install and fix the formula mixer, fact proved that adding mixer has played certain effect in engineering, but existing alr mode still has following problem:
At first, fix owing to add the blade position of mixer, thereby make stirring scope and highly fixing; For the relatively poor material of flowability; Stirrer paddle only works to the material of its peripheral certain space, causes the stirring dead angle at tank body or container bottom periphery easily, also is unfavorable for cloth; Secondly; When material liquid surface remains unchanged for a long time; The scum layer of the superiors is easy to generate the crust phenomenon, and fixedly the blade of mixer can't carry out effective broken shell owing under material liquid surface at this moment; When material liquid surface changed, phenomenons such as large tracts of land material wall built-up appearred in fermentation tank or container inner wall easily.
Summary of the invention
Main purpose of the present invention: a kind of brand-new stirring and distributing mode are provided; When material ferments in fermentation tank or container or is temporary; When adopting autocontrol blade frequency conversion mixer that stirrer paddle is rotated in a plane, also can move up and down along shaft, thereby realize the solid of material is stirred and uniform distribution through adjustment rotating speed control blade; Can guarantee jar even mass-and heat-transfer of interior material, improve the efficient of fermentation installation.
The present invention accomplishes by following technical scheme:
The present invention is a blade autocontrol frequency conversion mixer, comprises that variable-frequency motor (1), shaft (2), autocontrol stirrer paddle (3) three parts constitute.Wherein variable-frequency motor (1) is the state of fixed connection with shaft (2), is suit relative fixed state between shaft (2) and the autocontrol stirrer paddle (3).This mixer is installed in the fermentation tank body (4), and mixed material (5) is stirred, and autocontrol stirrer paddle (3) can move up and down along shaft (2) vertical direction along with variable-frequency motor (1) change in rotational speed.
Said shaft (2) is the oblong steel straight-bar for cross section, and its lower end and tank base are suit relative fixed state.
Said autocontrol stirrer paddle (3) adopts the high rigidity light material to process, and guarantees that it can effectively stir and can pass through shaft (2) change in rotational speed and in tank body, freely realize change in location material.
The centre bore of said autocontrol stirrer paddle (3) intermediate sleeve is ellipticity, and descends centre bore (7) and last centre bore (6) to be unidimensional ellipticity and concentric, but with respect to last centre bore (6) a low-angle twisting is arranged, and sleeve inner slightly is the inside spin shape.
Be the suit stationary state between said autocontrol stirrer paddle (3) and the shaft (2); For guaranteeing that shaft (2) can drive the rotation of autocontrol stirrer paddle (3) blade, must guarantee the minor face of the long limit of shaft (2) oval cross section greater than the oval centre bore of autocontrol stirrer paddle (3).
Said variable-frequency motor (1) is with shaft (2) and is fixedly connected, variable-frequency motor (1) rotate synchronously with shaft (2) and slewing rate consistent.Be the suit stationary state between shaft (2) and the autocontrol stirrer paddle (3), when variable-frequency motor (1) started, shaft (2) rotated in advance, drove autocontrol stirrer paddle (3) rotation subsequently and finally reached the speed unanimity.
Compare with existing alr mode, characteristics of the present invention are:
A) the autocontrol blade can be realized the three-dimensional on a large scale stirring of vertical space, especially can stir the top layer of material, has effectively avoided the crust problem on material top layer.
B) adjusting through variable-frequency motor realizes moving up and down of blade, has broken lamination, and active layer is expanded in the whole material.Impel microorganism fully to contact, strengthen the decomposition rate of material with material.
C) simultaneously, owing to can stir material on a large scale, can effectively promote newly to advance the even distribution of material.
Generally speaking, the present invention is simple in structure, and is easy to process, reliable working performance, and improved efficiency is obvious, can use at various fermentation tanks and receptacle.Simultaneously, the scope of application of the present invention is not limited to the biogas industry, also can in other industry, have in tank body or the container of mushy stage compound to use, and economic results in society are obvious,

The specific embodiment
As shown in Figure 1, said variable-frequency motor (1) can be regulated agitator shaft speed through variable-frequency motor when operation, and shaft drives autocontrol stirrer paddle (3), finally to reach the purpose of regulating blade position.
When shaft (2) stops or rotating speed when slow; Autocontrol stirrer paddle (3) is owing to receive gravity, buoyancy and shaft to give three power effects of less tangential force of blade sleeve; Three power stack back gravity accounts for leading; So autocontrol stirrer paddle (3) will move down along shaft (2), finally rest on the bottom of shaft (2);
When shaft (2) when rotating speed is very fast; Autocontrol stirrer paddle (3) still receives gravity, buoyancy and shaft to give three power effects of tangential force of blade sleeve; This moment, the junction of shaft and blade sleeve inner was an inclined-plane, on this inclined-plane because the blade sleeve is a female thread structure; The tangential force that sleeve is received can be decomposed into two power: horizontal direction and vertical direction, and the former lets autocontrol stirrer paddle (3) planar rotate; And if the latter then can make autocontrol stirrer paddle (3) rise along the axle vertical direction when enough big; When the latter and buoyancy when equaling gravity, the state that autocontrol stirrer paddle (3) hovers over a certain height in the tank body then possibly appear, be static relatively with shaft (2).
Through above two states, thus realize autocontrol stirrer paddle (3) in fermentation tank body (4) move up and down or static relatively, and everything all is the speed governing realization through variable-frequency motor.
