Abstract
The utility model provides a novel agitation shaft which can make a core shaft bear an even force, work stably and promote a balanced agitation and save the labour input and the energy. The utility model is mainly used at an agitation processing equipment installed at a fermentation and drying device. The utility model has such a technical scheme as follows: A novel agitation shaft comprises a core shaft and a plurality of agitation blades extending along the axial radial direction. The utility model is characterized by that a plurality of agitation blades in turn present a helix distribution around the surface of the core shaft with a plurality of knockout heads equipped at the tail of the agitation blade. A raised edge equipped with a winged slot may be equipped at the core shaft.
Description
Technical field
The utility model relates to the fermentation dried device in the fertilizer deep processing equipment, a kind of stir shaft in the particularly fermentation dried device.
Background technology
Along with constantly pushing ahead of livestock-raising industrialization, come into one's own just day by day about the environmental protection of livestock-raising field and the problem of the dirty processing of excrement aspect.Through the suitability for industrialized production flow process, processing and fabricating goes out high-quality fertilizer with feces of livestock and poultry, has both met the industry policy of country, helps environment protection again, so relevant processing units such as fermentation dried device are constantly introduced to the market.Yet in fermentation dried operation, adjustment has comparatively strict requirement to moisture content, and the equipment that has adopts the electricity oven dry, and this obviously consumes energy excessive and uneconomical.The self-heating effect that makes full use of sun power and fermentation is taken away steam and removed stink is not only environmental protection but also economic selection, and still, this need stir adequately and uniformly to giving birth to the muck material.Existing fermentation dried device also can't satisfy this requirement, because stir shaft wherein designs rationally inadequately, stirring wing on the stir shaft is simultaneously with respect to distributing with radial vertically, it only is the setting of staggering in a kind of interval, make to stir inhomogeneously, and mandrel is stressed also inhomogeneous, causes work not steady, noise is big, can't fully reach the technique effect of lowering energy-saving.
The utility model content
At the above-mentioned defective that exists in the prior art, the utility model provides a kind of can make that mandrel is stressed comparatively evenly, stable working and helping stirs and the novel stir shaft of lowering energy-saving.
The technical solution of the utility model is as follows:
A kind of novel stir shaft comprises mandrel and along the radially-protruding a plurality of stirring wings of mandrel, it is characterized in that: described a plurality of stirring wings distribute twist around the surface of described mandrel successively.
The tail end of described a plurality of stirring wings is provided with material thrasher.
Described material thrasher can be that bolt is connected and/or bearing pin connects, welds or riveted joint with the tail end of described stirring wing.
Described material thrasher can be plate shaped, sharp cone distal, knife-edge or hook rake shape.
The axis plane projection of described material thrasher is continuous distribution vertically.
The surface of described mandrel is provided with the convex edge, and described convex edge is around the winding stair distribution twist of the surface of described mandrel, and the coupling end of described stirring wing is connected by bolt with described convex edge.
Described convex edge is provided with wing inserting groove, and the coupling end of this wing inserting groove and described stirring wing is suitable.
Described convex edge and described mandrel are one or are welded as a whole.
Technique effect of the present utility model is as follows:
Because the utility model has adopted the helix structure design, and a plurality of stirring wings on the mandrel are distributed twist around the surface of mandrel, taken into account stirring wing like this and distributed with radial vertically, can make mandrel stressed comparatively even; This helix structure helps the rotation of stir shaft, can reduce the rotational resistance of self; When stir shaft rotated, the spiral that a plurality of stirring wings form distributed and makes that stirring to raw material is in continuously, stable and state normally, thereby the stir shaft stable working, and noise is less, stirred and the technique effect of lowering energy-saving thereby reach.
Because the utility model is provided with material thrasher at the tail end of stirring wing, and material thrasher possesses the selection of multiple pattern, this just is adapted to plurality of raw materials is carried out stir process, because different types of feces of livestock and poultry has different humidity, different density and different viscositys.For the inhomogeneous situation that exists in the homogeneous raw material, the mode that can take material thrasher to be used in combination is solved fully, and being removably connected of material thrasher and stirring wing tail end can be satisfied this application demand especially easily.The projection of each material thrasher on axis plane is the setting of continuous distribution state vertically, can enlarge the stirring scope to greatest extent, especially true for the moving type stirrer, like this when stir shaft rotates, material thrasher can be stirred to each some position in the groove pond substantially, eliminates the dead angle.
Convex edge of the present utility model and wing inserting groove thereof are designed to assembling condition very easily are provided, and wing inserting groove helps to improve the force-bearing situation of joint bolt.The integrated design of convex edge and mandrel can keep the intensity of mandrel.
According to same principle and functional effect, the utility model can also be used for the stir process equipment of vinasse, sugared slag etc.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Mark lists as follows among the figure:
1-mandrel 2-stirring wing 3-material thrasher 4-convex edge
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in the figure, stir shaft is made up of mandrel 1, stirring wing 2, material thrasher 3 and convex edge 4.Convex edge 4 is welded on the mandrel 1, convex edge 4 is along the circumferential surface winding stair distribution twist of mandrel 1, convex edge 4 is connected by bolted with the coupling end of stirring wing 2, load onto a stirring wing 2 on each convex edge 4 like this, and stirring wing 2 extends radially out along mandrel 1, see the shape that a plurality of exactly stirring wings 2 distribute twist around the surface of mandrel 1 successively on the whole.
Mandrel 1 is solid, circular among the figure, and in reality was made, mandrel 1 can also be hollow, hexagon.
Convex edge 3 is provided with the through hole that is used to connect among the figure, can also offer wing inserting groove on this basis.So not only help assembling and positioning, and force-bearing situation, the particularly joint bolt suffered shearing force when stir shaft work that can very improve joint bolt effectively can be born by the groove edge of wing inserting groove.
The above only is a preferred implementation of the present utility model.Should be understood that; for a person skilled in the art, based on the same principle of invention of the utility model, can also make some modification and improvement; and the technical program is in the application in other similar fields, but these all fall into protection domain of the present utility model.
