For making compost operation serialization, in the time of with above-mentioned stirring, material is transferred the function of certain orientation, rather need.Therefore, the rotary type stirring rake that can stir and transfer simultaneously is to accuse necessity, US Patent specification the 4th, the invention of 410, No. 348 grades is to be directed to this, this invention, along having with zig-zag (zigzag) track of material transfer direction approximate right angle direction and parallel direction two direction compositions, moving and have the whipping appts (equipment) that material is transferred to the rotary type stirring rake formula of roughly same direction function to stir, move according to this, with the handover of all material stirring it.
That is with first figure and second figure with such compost operation instructions it.1 expression also has according to the direction of arrow 2 partly, and material function and the agitator that stirs the rotary type stirring rake formula of function are transferred in short range (being called material miles of relative movement).3 nearby initial points 4 begin to move this agitator 1 from the compost exit, along with the compost transfer direction of arrow 2 rectangular direction roughly, that is expression walk crosswise the arrow 5 and 5 that direction moves ', the zig-zag track of the arrow 6 and 6 that moves with expression parallel direction that is the short range of stringer direction ' constituted as shown in the figure moves, arrive material inlet place 7 terminal point 8 nearby, all material will be as hereinafter described the samely, complying with the transfer movement of following agitator to stir, composting material, J → discharge, I → J, H → I ... move successively as the B → C, A → B, only transfer distance with material, according to the direction of arrow 2, full dose is transferred and is finished.
So, with compost transfer direction reverse direction, carrying out stirring paddle stirrer 1 successively and walking crosswise the material stirring transfer movement that direction moves based on rotary type.Stir transfer movement with this,,, be discharged to discharger 14 successively from compost exit 3 while transfer it with what all material in the fermenter 11 stirred.
Reach home 8, agitator 1 stops to stir, and is located at the door leaf 10 of partition 9 certainly, and moving to the path 12(that separates with wall 9 and fermenter 11 does not have material) direction of answer arrow 13 reaches initial point 4 again.
For example carry out once every day, for example raw material is dropped into A again, each day A → B → C → ... I → J ground, through 10 days, when moving, fermentation was being carried out, and is discharged from thereafter.The agitator of this rotary type stirring rake formula, as second figure, shown in the 3rd figure, be to dangle at vehicle body 21(fuselage) rotary type stirring rake 22 constituted, according to fermenter 11 in the backward directions of stringer direction arrow marks 15, i.e. the direction of arrow 2 is with material impact, move it, vehicle body 21 hangs on the scaffolding 20 that can move according to fermenter stringer direction, and can move according to the transverse direction of fermenter 11.
In the existent method, usually fermenter 11 all materials are generally stirred the stirring operation repeatedly that carries out mobile composting material with one time on the one frequency so at present.Therefore, a part of composting material in the fermenter 11 because of one time on the one stirring, and is subjected to stirring repeatedly.
The frequency of this degree, the stirring operation repeatedly that is carried out, when organic composition many raw material or initial stage, fermentation ardent fast prosperous during, very effective.Otherwise, during fermentation decomposition rates such as few raw material of organic substance or latter stage of ripening are slowly, shown in the 4th figure dotted line, when not reaching enough leavening temperatures, because of being subjected to stirring repeatedly, material temperature descends, sometimes can not obtain enough fermentations on the contrary, this is the place of problem.
The present invention is intended to solve present existing methods the problems referred to above, lowers the frequency that stirs repeatedly, for fermentation, provides the fermenter method of operation and the whipping device (device) thereof that are fit to the fermentating property frequency.
The present invention is for addressing the above problem, mobile agitator (stirring apparatus) in the fermenter (fermenter) of piling up composting material (compostabk matter) is provided, stir composting material and composting material is transferred to the compost exit from the place, feed(raw material)inlet on one side, carry out the fermenter method of operation of composting on one side, in this method, with the composting material travel direction abreast, from aforementioned inlet to aforementioned exit, field in the aforementioned fermenter is divided into n unit field (n is 2 above integers), in this n unit field, the base feed that all carrying out successively entering the mouth is certainly discharged first operation of compost and is spreaded all over aforementioned fermenter full width on one side from outlet, the aforementioned agitator that moves around, in the whole fields of aforementioned fermenter stirring composting material and with second operation of it handover on one side.The present invention aims to provide as fermenter method of operation and this method of feature to implement the directly device of use.
The 1st figure is the always plane explanatory view of existing method embodiment of expression, the 2nd figure is its oblique drawing (heterotropia), the 3rd figure is the side-view (sideelevation) of its stirring rake formula mixing part, the 4th figure is the fermentation appearance comparison diagram (ゲ ラ Off) of always existing (existing at present) embodiment and embodiment of the present invention, the 5th figure is the partition description figure in field in the embodiment of the present invention fermenter, the 6th figure is the plane explanatory view of the compost of field discharge from childhood operation on the embodiment of the present invention, the 7th figure is illustrated in the full field plane explanatory view of stirring operation repeatedly, the 8th figure is the partition description figure in field in other embodiment fermenters, the 9th figure is the plane explanatory view of this embodiment, the 10th figure is the cross section front elevation (cross section) of the 9th figure, the 11st figure is the sectional view (sectional view) of the 9th figure XI-XI, the 12nd figure is the sectional view of the 11st figure XII-XII, and the 13rd figure is an embodiment (embodiment) of rotary type stirring rake shape.
Now be illustrated in down with the embodiment of drawing the present invention.
Represented same of fermenter 11 and agitator and the 2nd figure and the 3rd figure.
As described in the 5th figure, with the travel direction (arrow 2) of composting material abreast, as long as from the place, feed(raw material)inlet 7 be divided into to compost exit 3 n the field 31.32.33.(of unit at this figure n=3. but n is the integer more than 2).
Once stir the richochet distance that is the each material miles of relative movement that are produced with agitator 1 again constituent parts field 31.32.33 is divided into little field A1, B1, C1, D1 etc.
Above-mentioned unit field 31,32,33 and little field A1, B1 ... Deng, be not with things such as partitions with it actual separating, but the field of dividing in the running operation.
About these fields, just like following, from the operation of (A) to (E), each operation every time of defined for example every other day, carry out successively.
Initial state, A1, A2, A3 are empty, other little field is composting material abrim then.
(A) first day, 31 li in first unit field, base feed was given in the ingress 7 the little field A1 and the little field D1 in comfortable exit 3, and compost is discharged.
(B) second day, 32 li in second unit field, base feed was given at the little field A2 of ingress 7 and is positioned at the little field D2 in exit 3 freely shown in the 6th figure, and compost is discharged.
(C) if the occasion of n＞3 in next unit field, exercise successively and (B) same operation every the time of defined (this example is one).In the time of n=2, (B) and (C) just unnecessary.
(D) n day (this example is the 3rd), 33 li in n (this example is the 3rd) unit field, 7 the little field A3 base feed from the ingress, 3 little field D3 discharges compost from the exit.
(E) (D) after the operation, shown in the 7th figure, spread all over the mobile agitator 1 in fermenter 11 full widths ground on one side, 3 move from the exit on one side, in whole fields of fermenter, stir compost and mobile to ingress 7.
After the operation of (A) to (E) is over as mentioned above, return to initial state (as long as A1, A2, A3 are empty) again, repeat above operation, 11 the running of fermenting.
The present embodiment, because of turn round according to such method of operation so, the stirring repeatedly that fermenter 11 is all, carried out once in per 3 days, the composting material in each little field can not be stirred in three days yet in fermenter 11, and is stagnating, during this period, shown in the 4th figure solid line, can reach suitable leavening temperature, also can guarantee completely between yeast phase, can carry out the high fermentation running of efficient, but the residence time is 0 at A3, at A2, D1 is one, and at A1, D2 is 2.
Like this, because of feed rate, discharge and all reduce event, raw material feed device and compost discharger 14 also can reduce its capacity.
It more than is the explanation of being done based on one time on the 3rd stirring frequency (being n=3).But work as n=2 or when being integer more than 4, every n day once stirs, and can guarantee fermentation time suitable and enough on the fermentation procedure.
Moreover above-mentioned embodiment is 3 the little field D1 in the exit just, and D2 or D3. agitator 1 be according to the right angle orientation of composting material travel direction, the only explanation of doing by the output of defined for a time.But decide output when very big, at little field D1, among D2 and the D3, agitator 1 also can repeatedly carry out the composting material travel direction and move it discharge with the direction at its right angle.
The 8th～12 figure represents other embodiment.
As the fermenter of above-mentioned mode, particularly work as fixed time very long the time, it is described for example to resemble the 8th figure, the limit b of the compost travel direction of arrow 2 is shorter, and longer with the limit a at its right angle, forms minor face b, the rectangle state of long limit a.
For example, suppose that it is that Y. fermentation number of days is N day for X. length that a daily crude capacity supply with to be gone up required width, stirring frequency is every n day one time, and then a and b be as following formula,
a＝nx
b＝NY/n
In the equipment of at present existing (always), its degree is roughly
X=10m, N=10 day, Y=3m is so the event of n=1 day becomes a=10m, b=30m.
As mentioned above, stirring frequency is decided to be one time on the 4th then because of
X=10m, N=10 day, Y=3m is so the event of n=4 day becomes
a＝40m，b＝7.5m
B becomes less than a, and length-breadth ratio is to accuse to reverse.
For such fermenter 11,, always existing shown in the 2nd figure as the 1st figure, in the both sides of fermenter, along the travel direction (arrow 2) of composting material, when laying mobile steel rail (rail) scaffolding 20, (span) is very long because of span, and weight is to accuse to become big.
Therefore, for the fermenter 11 of b＜a in this wise, as the 9th figure, the 10th figure is described, the travelling scaffold 20 of agitator 1 for can according to rectangular length direction move around (promptly with the rectangular direction of composting material travel direction shown in the arrow 2) be striding fermenter 11 minor faces length and by being equipped with, in order to move around, be on travelling scaffold 20, to set one by the rotary type stirring rake 22 of vehicle body 21 pillars along the travel direction of composting material.
The embodiment (embodiment) of the 8th figure to the 10 figure, expression n=4 every 4 days be with whole fields of fermenter 11 stir repeatedly, whole fields of fermenter 11 are divided into 31 again, 32,33, unit fields such as 34, in each unit field, be divided into A1 again, B1 ... C4, D4 ... etc. little field.Rotary type scaffolding 22 is to be moved, and only becomes at n at 4 o'clock from 3, roughly same with above-mentioned example.But the travel direction of travelling scaffold 20 and relative therewith rotary type stirring rake 22 then is different, and the moving of arrow 2 directions undertaken it by rotary type stirring rake 22 the moving relative with travelling scaffold 20.And rectangular moving of direction therewith then undertaken it by travelling scaffold 20 moving.Illustrate in greater detail it.In the 9th figure, 40 is the fermentation field that expression has oblong plan shape, is constituted with symbol 42～45 represented limits by 4.The outside on the limit 42,43 in fermentation field 40 is provided with mobile rail, as guide rail (guidewa_y), and the timed interval of mobile rail 46,47 roughly equates.Travelling scaffold 20 is across between these two the mobile rail 46,47 and be laid on the mobile rail 46,47, moreover agitator 1 is located on the travelling scaffold 20, can along travelling scaffold 20 transverse directions move freely.
Rely on agitator 1 and travelling scaffold 20 moving, agitator 1 moves along the sawtooth track shown in the arrow from initial point S T to terminal, spreads all over the composting material that whole fields in fermentation field 40 will piled up and stirs it.Then, return to initial point S again by the outside on limit, fermentation field 44.
Certainly, in the present embodiment, the motion track of agitator 1 is not limited to the track shown in the 9th figure.Because moving of agitator 1 shown in the 9th figure, the whole composting materials in the fermentation field 40, the avris of mobile certainly rail 47 are shifted to the avris of mobile rail 46.Now with the 11st figure this thing is illustrated in greater detail in following.
Among the 11st figure, the composting material in the fermentation field 40, the height of accumulation is higher than the rotary type stirring rake 22 that is provided in agitator 1.
The turning direction of rotary type stirring rake, shown in arrow, when stirring, the composting material of mobile rail 47 avris is to leap on the rotary type stirring rake 22 and be transferred to the avris of mobile rail 46.
By porous plate (perforated plate) 52 airway 53(air duct) below air is sent into or is extracted out and use inlet mouth (diffuser) to replace porous plate also effective of mediating from fermentation field 40 as air supply means.Moreover, among the 11st figure, omitted air and sent into the blower (blower) of extracting usefulness out.
The rotary type stirring rake is relying on vehicle body 21 to hang down from agitator 1, turns round by motor 55.The surface of revolution of rotary type stirring rake 22 (being plane of rotation) that is with 20 one-tenth parastates of travelling scaffold, so disobey the turning direction of rotary type stirring rake 22, composting material is the avris that is transplanted on another rail from the avris of a mobile rail.One side of portable foot rest 20 move on two mobile rail, but this holding power that moves rail can increase and decrease along with the weight of portable foot rest 20.
The 12nd figure is the sectional view (sectional view) of the 11st figure XII-XII.Rotary type stirring rake 22 is located at the both sides of vehicle body 21, agitator 1 is about travelling scaffold 20, no matter move to that direction, all can be according to the side of rotary type stirring rake 22, stir accumulation horizon, among the 12nd figure, the driving that 56 expressions are moved on travelling scaffold 20 agitator 1 stops, but the motor that drives rotary type stirring rake 22 then is omitted.
The 13rd figure is the stringer 58(beam of a rotary type stirring rake 22 in the suitable embodiment (embodiment) of rotary type stirring rake 22) install according to angle same from rotating shaft 57, be radial, and mix plate 59A, the be fixed head both sides of stringer of 59B.According to the rotary type stirring rake of this shape, no matter take the sort of revolution (rotation) direction (just change or reverse) all can be engaged in suitable stirring and handover.
Comply with the occasion that the agitator track shown in the 9th figure turns round, because of the composting material in the fermentation field 40 from the limit 43 avris be shifted at leisure the avris on limit 42 so, raw material is according to the supply method of not representing on figure, be fed in the fermentation field 40 along limit 43, and be subjected to decide fermentative processing composting material be that take out 42 termination from the limit.Therefore on the floor of limit 42 and 46 of mobile rail, 42 is to form one to fall a mouthful 60(and fall mouthful along the limit), below falling mouth 60, as set an endless belt conveyor of on figure, not representing (belt conveyor), then can easily collect compost.
Moreover the present embodiment is in the occasion of batch-type (batch type), and is also applicable.In this occasion, for example in whole fields in fermentation field 40, piling up raw material.With one just changeing one reverse revolve (returning) veer running rotary type stirring rake 22, it is last that composting material only can move the distance that once stirs handover, the result may finish identical fermentative processing in roughly the same field.In such occasion, the shape of the rotary type stirring rake shown in the 13rd figure is very effective.
Moreover, in the 10th figure, slideway (runway) trave lling girder of bridge crane formula (overhead crane) is arranged, as portable hand frame 20, but the height difference of left and right sides rail, a side have half type (semi portal) of pin or both sides all to have the gantry type moving body of pin also can.
When can be provided in composting material according to the present invention and fermenting operation, can guarantee enough fermentation times, simultaneously, the fermenter method of operation that the capacity of raw material feed device and compost discharger can be diminished and the whipping device (device) of fermenter produce effects in practicality greatly.
