But; The shortcoming that all known method and apparatus have is; Fluctuation from its bulk density of slurry of cyclone is very big; Make to be difficult to produce the bale packing materials (bale) that has only very little deviation of weight, only if, in a bale packing materials, all can not revise any deviation usually because suppress a bundle material down.
Summary of the invention
Therefore, the present invention is based upon on the basis of the method and apparatus that said type is provided, and wherein, its weight of pressure-formed bale packing materials can be easily and regulated accurately and control.
Realize this task through a kind of like this method, wherein before press, slurry is weighed, when reaching predetermined weight, then interrupt slurry being provided to press at the slurry feed.
This method is special to propose a kind of equipment in order to implement, and has the device to press supply slurry, according to the present invention, it is characterized in that with weighting apparatus be arranged on feed arrangement near.
In the present invention, weighting apparatus is arranged between the press that moves the slurry that provides continuously from cyclone and the batch processing process, when therefore reaching predetermined weight when circulating for suitable compacting, can interrupt the feeding of slurry.Different with methods known in the art and equipment; Method and apparatus according to the invention can be set the slurry weight to the accurate feeding of press accurately; Therefore can avoid occurring the follow-up or deferred reaction taked about the bulk density of any variation of slurry, and then avoid the bale packing materials final weight undesirable large deviation to occur.
In preferred embodiment according to the method for the invention, in the batch processing process, slurry is weighed.This means, the slurry of specified quantitative is weighed, until reaching the weight that needs; At this moment, interrupt slurry being provided, the slurry quantity after weighing is fed into press to weighting apparatus; Then, carry out again to press supply slurry, and begin new weighing process.
In another preferred embodiment of the present invention, the feed flow that slurry is wadded a quilt with cotton is divided into several strands of partial flows, is preferably two strands, wherein, can at least two strands of slurry wadding streams be provided to press, can measure the weight of these feed flows.Embodiments of the invention have utilized the advantage that two strands of slurry feed flows are provided from two side direction press, make in less compacting circulation, to make bale packing materials.
Another progress of the present invention also provides the slurry wadding feed flow of part, and the feed flow quality according to weighing provides by this way, that is, two strands of feed flows have essentially identical quality.In this embodiment of the present invention, control by this way slurry stream is divided into two strands of feed flows, that is, two strands of feed flows have essentially identical quality.In the aforementioned embodiment; Measure the weight of per share feed flow; The slurry wadding also can be provided like this, that is, the final weight of bale packing materials is an entirely accurate; But the embodiment with feed flow of two bursts of basic identical quality has guaranteed under each situation, the slurry of two bursts of basic identical amounts of compacting in the compacting circulation of both sides.
In situation known in the art, can continuous slurry stream be divided at least two strands.Yet in the present invention, can slurry stream be divided at least two strands of feed flows through the weight according to feed flow and make improvements, the quality that makes two strands of feed flows have is basic identical.This means, be not arbitrarily or uncontrolled feeding is divided into the feed flow more than one to slurry, but the situation that can be immediately feed flow be departed from ideal weight is corrected.
In preferred embodiment according to the method for the invention, utilize weighing chamber (weighingchamber) to weigh to feed flow, wherein, when the total weight of the slurry in the weighing chamber reaches predetermined total weight, with the filling mouth sealing of each weighing chamber.In this embodiment of the invention, guaranteed that pressure-formed slurry total weight is consistent with predetermined weight in each corresponding compacting circulation, and irrelevant with independent slurry weight at each weighing chamber.Present embodiment also makes it follow a kind of method, wherein, like this slurry stream is divided into two strands of feed flows, makes that the slurry weight in weighing chamber is basic identical, because like this rectangular distribution of feed flow can be provided subsequently.
Yet, optional, also can claim the weight of feed flow at weighing chamber, and when the slurry weight of each weighing chamber reaches predetermined value, close the filling mouth of weighing chamber.In this case,, promptly close each weighing chamber, need not to guarantee correctly separately feed flow like this, but still possibly realize the accurate total weight of bale packing materials in case the slurry weight of each weighing chamber reaches predetermined weight.
Because the weight that exists various factors to cause to measure can not be accurately consistent with the actual weight of slurry; One embodiment of the present of invention can provide weighs to the finished product bale packing materials; And if the weight of last bale packing materials departs from the weight sum of each feeding thing, then the weight measurement of weight measurement in the weighing chamber or the slurry feeding that provides to weighing chamber can be repaired.Like this, the actual weight of bale packing materials is compared with the weight of each feed flow, thereby the feed flow of can control survey correcting and/or flow to press is corrected.
In order to implement to be used for the slurry wadding is pressed into the method for bale packing materials faster, another improvement of the present invention can be wadded a quilt with cotton to slurry before being divided into two strands of feed flows and carry out pre-compacted will starch wadding at least.Through pre-compacted, can more highdensity feeding slurry be offered press, thereby only need still less compacting circulation just can reach the final mass of bale packing materials.
In the device in accordance with the invention, weighting apparatus can be installed in the skewed slot, through skewed slot, slurry is offered press.And, the skewed slot that is divided at least two chute section can be provided and the weighting apparatus that can be installed in each chute section is provided according to equipment of the present invention.As previously mentioned, this embodiment provides a kind of method, accurately measures the weight of the slurry feed flow in each chute section, so that can accuracy control the slurry feeding be divided into an above feed flow, and it is provided to press.
Description of drawings
Below, with reference to description of drawings a preferred embodiment of the present invention.
Fig. 1 illustrates the schematic cross sectional view according to equipment of the present invention;
Fig. 2 is the schematic cross sectional view at the top of this equipment; With

The specific embodiment
Fig. 1 can be by summary for comprising following part to the equipment shown in Fig. 3: feeding skewed slot 1; Feeding dried slurry wadding through this skewed slot, is depassing unit or pre-compressing device 2 then, distributing device 3; Two chute section 4; Two 5, two of weighting apparatuss have the preparatory filled chamber 6 of pusher 7 and have pressing die 34 and the compacting chamber 8 of compacting drift 9.At pre-compressing device 2 shown in the section-drawing of Fig. 2, comprise two on-cycle rotating bands 10, it forms nip region 11, and this nip region narrows to form wedge shape basically downwards in the embodiment shown.
Ventilative rotating band 10 is around five rollers and in the present embodiment on the slidingsurface of the perforated plate 12 on the suction box 13.Because rotating band 10 is ventilative, the gas that during pre-compacted, extrudes can be discharged by suction box 13 through rotating band 10.At the sense of motion of rotating band 10, top roller 14 is a draw roll, is suction box 13 and two press rollers 15 then.Driven roller 17 is positioned at the minimum flex point of rotating band 10, and dancer rools 16 is positioned at a side opposite with suction box 13.The structure of two structures of this that faces with each other is essentially identical.
The slurry wadding that comes out from airer gets into feeding skewed slot 1 from the top, get into the wedge pressure compact space 11 between two rotating bands 10 then, and guiding slurry wadding is carried out preliminary pre-compacted.Rotating band 10 is that the weight of slurry has improved the pre-compacted rate with the advantage that the vertical layout that compresses space 11 has.For example, compressing ratio can be 1: 20.When slurry net that existence compresses, it launches once more a little, and still, the pre-compacted rate that continues is equivalent to 1: 4 ratio.
Pass through the constant pressure in the preset range by unshowned hydraulic actuating cylinder; Keep the gap length between the driven roller 17, still, the framework on for example the rotating band 10 on right side or its are located at is supported on the top of pivot bearings; Therefore shown in double-head arrow 18, the lower end can swing.The rotating band on right side or firm being fixed on the machine frame of its framework.Hydraulic actuating cylinder acts on two rotating bands 10 or two frameworks.Because pivot bearings or the constant pressure that applies, can be by this way, by the upwards swing or the space is broadened absorb the heterogeneity of slurry feeding of the rotating band 10 on right side, prevent gambling plug and damage like this to machine.
Below pre-compressing device 2, feeding skewed slot 1 is divided into two chute section 4, causes that the slurry pad is divided into two nets.Be provided with the for example cutter sweep of cutter 19 shapes, it can rotate an angle, for example 10 degree.This makes and can change the pulp ratio that falls into left side and right side chute section 4.
Slurry separately falls into dashpot 20 then, and it can be closed by the butterfly valve of installing with the mode that can rotate 21 in the bottom.Be weighting apparatus 5 below butterfly valve 21, it can as shown in Figure 3ly be constructed.Weighting apparatus 5 shown in the present embodiment has the weighing chamber 22 that comprises four walls 23 and 24, and wall is being that the shape orientation of truncated pyramidal inclines towards each other basically, so the cross-sectional plane of weighing chamber 22 becomes big from the top to the bottom.Open at the top of weighing chamber 22, butterfly valve 21 sides mounted thereto.In the lower end, weighing chamber 22 has two other butterfly valves 25, and is as shown in Figure 1.Pressure medium cylinder 26 is set, opens and closes butterfly valve, and link to each other with valve 25 through lever 27.One of them wall 23 has two observation windows 28 and breather pipe 29.
Weighing chamber 22 hangs from machine frame 30 at three points, in the weight of 3 load cells of locating, 31 measurement weighing chambers and institute's inclusion, i.e. slurry amount in the weighing chamber of any moment.
Below the butterfly valve 25 at each weighting apparatus 5 place, have preparatory filled chamber 6, material to be compressed is falling into preparatory filled chamber after discharging from weighing chamber 22.Slide-valve 32 is installed in preparatory filled chamber 6 tops, when preparatory filled chamber 6 is full of, closes slide-valve.Material in the filled chamber 6 inwardly is transported to compacting chamber 8 symmetrically in advance; And further compressed down the auxiliary of pusher 1, as known in the art, then; Compacting drift 9 is pressed into slurry in the pressing die 34 at last, and it is pressed into final volume.Above pressing die 34, be another slide-valve 33, it can be used for occlusion pressure molding 34.
This operation of equipment is in proper order: for example under about 70 degrees centigrade temperature, the slurry wadding that for example contains 88% dry leaves the cooling cyclone with AIR MIXTURES.The slurry wadding falls in the feeding skewed slot 1, and this skewed slot is full of for 50-70% during operation.The dead weight amount of slurry wadding causes that the slurry wadding quickens to be fed in the pre-compressing device 2 of below.Here, except that between the band of gas 10 slurry is carried out exhaust at two, and the loose pad of compacted formation.The volume that leaves the slurry net of pre-compressing device 2 then be approximately original slurry flco long-pending 1/4th.At distributing device 3, the slurry net is separated.Measurement according to weighing chamber 22 realizes optimized separately ratio, that is, set and the frequent separately ratio of correcting, and comprises the slurry of basic identical amount to guarantee two weighing chambers 22.
Then, the slurry net that can be divided into independent sheet falls into suitable dashpot 20, if butterfly valve 21 is opened then got into weighing chamber 22 then.In case reach the preset slurry weight in the weighing chamber 22, butterfly valve 21 cuts out, half slurry net that the result forms subsequently is collected in the dashpot 20.Simultaneously or after a while, open the bottom butterfly valve 25 of weighing chamber 5, slurry falls into following preparatory filled chamber 6.In case weighing chamber 22 is emptied completely, bottom butterfly valve 25 cuts out, and crown valve 21 is opened, and slurry can enter weighing chamber 22 from dashpot 20 once more like this.Air in that this process is removed is overflowed through breather pipe 29.Crown valve 21 still stays open now, in weighing chamber 22, reaches the filling weight that needs.
In this process, close the slide-valve 32 that is positioned at each preparatory filled chamber 6 top, the pushers 7 in the preparatory filled chamber 6 that therefore present all sidepieces are all closed can be shifted slurry in the compacting chamber 8 of pressing die 34 tops onto.Position before pusher 7 remains on then forms the sidewall of suppressing chamber 8, suppresses drift 9 simultaneously slurry is compressed to final volume in pressing die 34.Turn back to the top position when suppressing drift 9, pusher 7 moves once more backward.Then, weighing chamber 22 is discharged into preparatory filled chamber 6 once more with inclusion wherein, suppresses circulation again, and pusher 7 promotes these inclusion to compacting chamber 8, suppresses drift 9 last compacting slurry material in pressing die 34 then.For example, after per two compacting circulations, promptly obtain bale packing materials.Compacting drift 9 is pressed onto on the bale packing materials.After about 2 seconds, pressing die 34 moves down.After amounting to about four seconds, the compacting drift slowly moves up, in case compacting drift 9 is given way, slide-valve 33 just is pushed forward.As a result, filled chamber 6 can be filled once more in advance.
Discharge bale packing materials then.Subsequently, the bale packing materials tapping equipment turns back to its reference position, and pressing die 34 moves up once more, prepares compacting circulation next time, and slide-valve 33 is withdrawn once more.
Like this, the premoulding device 2 in this equipment can continuous handling, in the batch operation program, can carry out weighing and being pressed into bale packing materials at last of slurry simultaneously.
