Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described.It should be noted that, the technical characteristic mentioned in the present invention, not having all can carry out independent assortment under conflicting prerequisite, is not construed as limiting the present invention.
As shown in Figure 1, a kind of agitating device realizing the fermentation of solid waste layer-transferred, comprising: a central shaft 8; One for axially pushing the conveyor screw 7 of material, and being fixed on this central shaft 8 side with one heart, is that axisymmetrical distributes with central shaft.Conveyor screw 7 is tapering type extension from axle head to axle centre position.Conveyor screw 7 is large near feed end side diameter, and the diameter of close stirrer paddle 9 side is little.Central shaft 8 opposite side is fixed with some stirrer paddles 9 around axis body, and stirrer paddle 9 is coaxial with conveyor screw 7.During use, this central shaft 8 is fixed in reactor, and material pushes to stirrer paddle 9 place by conveyor screw 7.Stirrer paddle 9, by stirring material, makes it fully mix and ferment.The material fermented the most at last exports to outside reactor, realizes processing continuously.In present embodiment, in order to reduce the weight of agitating device, central shaft 8 adopts hollow shaft.
Traditional reactor in use, maximum problem is that new and old mixing of materials rate is too high, although inside reactor divides the fermentation maturity degree of material very high, but owing to new material and this partial material being mixed in whipping process, therefore not yet complete the material of sweat at output products without inevitably outputing a part simultaneously.Therefore, in order to solve this technical problem, the laying standard of stirrer paddle 9 is: the propelling movement power not producing centrally axle 8 axis in rotary course.Stirrer paddle 9 only stirs material for circumferential, and new material can not be pushed to marine store region, forms layering fermentation system in reactor.This system can reduce the composite rate of new marine store greatly, effectively controls the solid material time of staying in the reactor, improves the degradation efficiency of outputting material, promotes end product quality.
And in the process, consider well-beaten demand, stirrer paddle 9 cross section is set to assume diamond in shape shape, and rhombus major axis is axially parallel with central shaft 8.And the use of rhombus blade also can increase its rigidity and stability greatly, reduce the risk of blade fracture.
The stirrer paddle of above-mentioned condition has multiple layout type, have employed following manner in present embodiment: stirrer paddle 9 is laid on the different sagittal planes of central shaft 8, and the paddle type that the stirrer paddle 9 in each plane is formed is straight leaf open turbine formula.Specifically, namely so stirrer paddle is divided into some groups, often group is distributed in one with in the plane of central shaft 8 axes normal.Blade all adopts straight leaf, and distributes around the open turbine formula of axle circular array.Stirrer paddle and central shaft angle are 90 °, ensure that material makes filler radially flow in agitating device rear end, have axial stream hardly, significantly reduce axial backmixing ratio, ensure different fermentations time material rotten degree.
Although the blade distribution of straight leaf open turbine formula can greatly reduce axial backmixing, in actual test process, in Different Plane, the quantity of blade is different or arrange the axial Promoting effect that angle difference still can cause great-jump-forward.Therefore, in present embodiment, stirrer paddle 9 quantity on different sagittal plane equal and centrally axle 8 axis direction projection overlap.Namely on different sagittal plane, the stirrer paddle 9 of a certain angle is all on an axial plane of central shaft 8, the blade also equal same design of all the other angles.Thus, in whipping process, the material in reactor on different sagittal plane is all under the driving of stirrer paddle 9, and move in identical migration rule, axial displacement is reduced to minimum.
The spacing of the different sagittal planes that stirrer paddle is arranged can adjust according to the actual requirements, in the present embodiment, for the ease of the regulation and control of operating personnel, equidistant between different sagittal plane.
And based on above-mentioned agitating device, be installed in cylindrical shell 5, just define a kind of reactor realizing the fermentation of solid waste layer-transferred.As shown in Figure 2, the central shaft 8 of agitating device is arranged along the axis of cylindrical shell 5, and cylindrical shell 5 establishes charging aperture 1 near conveyor screw 7 side, is provided with discharging opening 2 near stirrer paddle 9 side.Conveyor screw 7 and stirrer paddle 9 axial length are than 1/5 ~ 1/8.The material that charging aperture 1 falls is carried by conveyor screw 7.Cylindrical shell 5 both sides are sealed by detachable capping 4.Central shaft 8 two ends are supported by support member 6.In present embodiment, support member 6 adopts bearing.Be connected with reducing motor and realize rotating outside the capping 4 that cylindrical shell is stretched out in central shaft 8 side.Central shaft 8 is intermittent rotation, and rotating speed is 3 ~ 7r/min.
Operation principle and the process of reactor of the present invention are as follows:
The solid waste collected enters reactor by charging aperture 1, and material pushes to stirrer paddle 9 place by conveyor screw 7.In stirrer paddle 9 region by temperature control, control ventilation, carry out in-situ fermentation, by the batch (-type) effect of stirrer paddle 9 in sweat, realize the strong stirring of material at circumferencial direction, but axial backmixing effect is more weak, thus realize layer-transferred fermentation, effectively control the time of staying of fermentation materials.
The core difficult problem that solid waste in-situ fermentation exists is that residence time of material is long, material becomes thoroughly decomposed uneven, the main cause causing this problem to produce is that the mixing of materials of the different time of staying is excessive, particularly in dynamic response device, when there is biological respinse, between material, axial backmixing rate is higher, causes the time of staying that accurately cannot control material.At present, on market, existing twin axle reactor arranges two shafts side by side at inside reactor usually.In order to form contrast, by single axle reactor of the present invention and twin axle reactor, by using the modeling of EDEM discrete element, calculating simulation is carried out to its axial backmixing rate.As shown in Figure 3, Figure 4 (what show in Fig. 3 is the situation of two reactor couplings), difform particle represents the material of different batches, shows the mixing of materials state after shaft pushes in figure.Found by simulation, twin axle reactor is while realizing material laminar flow, and axial backmixing rate reaches more than 42%; And single axle reactor is found by simulation, axial backmixing rate is only 17%, is obviously better than twin axle reactor.In effective realization response device, the layer-transferred fermentation of material is particularly applicable to layering fermentation, and Different periods mixing of materials ratio is little, ensures that the same period fully mixes simultaneously, fully contact with medium, microorganism, the time of staying of accurate control each section of material, improve Fermentation efficiency, ensure product quality.Compared to twin axle reactor, it is more than the twice of twin axle reactor that single axle reactor obtains product rotten degree (percentage of seedgermination), can reach more than 50%.
The drawings and the specific embodiments of the present invention all only understand essence of an invention better for those skilled in the art, are not construed as limiting invention protection domain.Any technical scheme belonged within spirit of the present invention all belongs to protection domain.
