The specific embodiment
Below, the form of implementation that present invention will be described in detail with reference to the accompanying.
(form of implementation of the manufacturing method and apparatus of lightweight curing materials)
(the 1st form)
Fig. 1 is the flow chart that the manufacture method of light weight curing materials of the present invention is shown.As the mobile raw material that uses in the present invention,, then do not consider kind especially, but preferably use industrial wastes such as muddy water, earth, pulpous state lime and iron and steel slag if comprise moisture and solid constituent.As use muddy water and earth, then can make light soil.
The cumulative water-oil ratio of this accessory substance is different.Therefore, in the present invention, elder generation in proportion adjusting device 1, measures proportion with mobile raw material supplying, simultaneously, for the match ratio that makes afterwards the curing agent that mixes and lighting agent according to its measurement result becomes desired ratio by carrying out appending or remove and comparing recanalization of moisture.Concrete example for proportion adjusting device 1 will be explained below, and suitable use has the function of dissolving free-flowing material, than the recanalization function and the device of mixed function again.
Carry out the adjusted free-flowing material of proportion and pass out to transfer line by pump installation 2.The 1st pipeline type mixer 4 and the 2nd pipeline type mixer 5 are set on transfer line, and mobile raw material is sequentially by them.These the 1st pipeline type mixers 4 and the 2nd pipeline type mixer 5 satisfy necessary condition of the present invention, have mixed pipe line, be supported on the device for revolving and driving of shaft component in the mixed pipe line, the helical blade that is set up in parallel successively from upstream side and stirring vane, shaft component and be located at least 1 additive supply port at the position corresponding with the stirring vane of shaft component coaxially on the outside of shaft component; Be transplanted on additive supply port rear flank through the fluent material that will supply in the mixed pipe line by the helical blade that is subjected to turning round driving, from the additive supply port additive is supplied to this fluent material, by the stirring vane that is subjected to turning round driving these fluent materials and additive are mixed, then can use both also can use different formations in the identical formation.The preferred concrete example of pipeline type mixer will be explained below, but the inventive method is not limited thereto, and also can use pipeline type mixer in the past.
In the 1st pipeline type mixer 4, by in the process of this pipeline, the curing agent of supplying with from curing agent supply device adds from the additive supply port of rotating shaft component and mixes.In illustrated example, powder body curing agent such as cement (is the raw material of curing agent in this occasion) are supplied to curing agent supply device 6 at any time from silo 6s, mix with the liquid of water etc. and after forming the pulpous state curing agent, it is supplied to the 1st pipeline type mixer 4 by curing agent supply device 6.
The mobile raw material that has added curing agent in the 1st pipeline type mixer 4 then leads to the 2nd pipeline type mixer 5.In the 2nd pipeline type mixer 5,, add also lighting agent such as gaseous mixture infusion, foam beads pellet, the broken shred of foamed resin by in the process of pipeline.
Like this, owing to, make mobile raw material in the handover process, be changed to the lightweight curing materials by at the 1st and the 2nd curing type mixer 4,5.At this moment, in this 1st form of implementation, it is characterized in that: only adopt the original pressure that passes out to the pump of handover pipeline by the mobile raw material after will finishing than recanalization to make it, become very simple and energy-conservation formation by the constituting of the 1st and the 2nd curing type mixer 4,5.In addition, the match ratio of the mobile raw material of the 1st and the 2nd pipeline type mixer 4,5 and curing agent or lighting agent can by measurement send 4 of pump and the 1st pipeline type mixers flow, correspondingly the quantity delivered or the lighting agent quantity delivered of curing agent supply device 6 are adjusted or are controlled and determine therewith.
In illustrated example, banket when dropping into the lightweight curing materials as the back side of the retaining wall W that covers domatic G, it is dropped in the process of the mobile raw material of domatic handover, making it be changed to lightweight curing materials C.
(the 2nd form)
On the other hand, example shown in Figure 2 illustrates system's configuration example of occasion of pipeline type mixer 4 ' (detailed content illustrates in the back as the 5th mixer example) of hopper supply-type.That is, mobile raw material supplying similarly carries out than after the recanalization with example shown in Figure 1 to proportion adjusting device 1, quantitatively tells device by rotary feed appliance R etc. and tells scheduled volume continuously, fall supply to the 1st pipeline type mixer 4 '.
Supply to the 1st pipeline type mixer 4 ' mobile raw material transfer successively by the release function (details illustrates in the back) of this mixer, simultaneously, in this handover process, add to mix curing agent from curing agent supply device 6 ' supply.Illustrated example imagination at any time with powder body curing agent such as cement from silo 6s supply to curing agent supply device 6, curing agent supply device 6 under the state of powder body, continuously ormal weight is supplied to the 1st pipeline type mixer 4 ' occasion.In this occasion, the match ratio of free-flowing material and curing agent can by preestablish rotary feed appliance R and curing agent supply device 6 ' quantity delivered determine.
The 1st pipeline type mixer 4 ' in, the mobile raw material that has added curing agent then supplies to the 2nd pipeline type mixer 5 by force lift 2, same with above-mentioned example, in the process of the pipeline that passes through the 2nd pipeline type mixer 5, add the mixing light agent, be changed to the lightweight curing materials.In this 2nd form, by the force feed flow of force lift 2 quantity delivered with respect to the free-flowing material of the 2nd pipeline type mixer 5 is determined, for this reason, between force lift 2 and the 2nd pipeline type mixer 5, flowmeter 3 is set, adjust or control lighting agent quantity delivered corresponding to its measurement result, can determine the match ratio of the 2nd pipeline type mixer 5.Other, identical with the 1st form basically.
(the 3rd form)
In above-mentioned example, as pipeline type mixer, the mixer that is provided for adding the mixer of curing agent respectively and is used to add the lighting agent, in the present invention, as shown in Figure 3,1 pipeline type mixer 40 (the pipeline type mixer 40 among the figure is suitable with example shown in Figure 11 described later) is provided with a plurality of additive supply ports at the length direction of shaft component with having appropriate intervals, can add curing agent from the supply port of upstream side, also can add the lighting agent from the supply port in downstream.In this occasion, need make to mix portion head, but see on the whole, can be cured the interpolation mixing of agent and lighting agent by 1 pipeline type mixer 40, so, have the advantage that can make system compactization.
(form of distortion)
As from the above-mentioned the 1st and the contrast as can be seen of the 2nd form of implementation, in the occasion of in series using pipeline type mixer, force lift can be configured to suitable position (1 position or a plurality of position) and carry out material and transfer.
In addition, as long as add mixed curing agent and lighting agent in proper order according to this, then also can append one or more pipeline type mixers again, perhaps append one or more additive supply ports at shaft component, add material of the same race or xenogenesis before adding curing agent and lighting agent or thereafter.Specifically, after the interpolation that is cured agent mixes,, then, consider to mix more variations such as bubble as the 2nd lighting agent as the 1st lighting agent mixing coal ash.
(form of implementation of pipeline type mixer)
(the 1st mixer example)
Fig. 4 illustrates the form of implementation that earth grade in an imperial examination 1 fluent material X force feed is supplied to the occasion in the pipeline type mixer 10 by pump etc.Promptly, this pipeline type mixer 10 is coaxial earth's axis bolster member 14 in the inner space of the mixed pipe line 12 with upstream side supply unit 12i and downstream discharge portion 12e, successively a plurality of helical blade 14s and stirring vane 14m is being set devices spaced apart vertically from upstream side on the outer peripheral face of shaft component 14.The base end part of shaft component 14 penetrates into outside the pipe by the S word sigmoid portion of mixed pipe line 12, is connected to device for revolving and driving 15 transferring power such as motor relatively.In addition, shaft component 14 forms hollow form, forming position formation and the inside and outside jet 14a that is communicated with suitable in the way of part with stirring vane, simultaneously, by rotary joint 16 with the cardinal extremity open communication to feeding pipe 17, from this feeding pipe 17 by in the shaft component 14 and jet 14a the 2nd fluent material Y is supplied to the formation part of stirring vane 14m by this order.
The 1st fluent material that has carried out rectification by helical blade 14s is then after the upstream side of jet 14a prepares stirring by the stirring vane 14m that is subjected to turning round driving, with the 2nd fluent material Y interflow from jet 14a weight feed, the 1st fluent material and the 2nd fluent material are mixed by the stirring vane 14m that is subjected to turning round driving in jet position and its downstream, and this stirs the mixture and discharges by discharge portion 12e.
Particularly supply with the occasion of the 1st fluent material X as this example at force feed, in order to bring into play above-mentioned rectified action, the rectifiable amount of the unit interval of suggestion helical blade 14s becomes the quantity delivered of the unit interval that is not less than the 1st fluent material X.The rectifiable amount of this helical blade 14s can be obtained by test, and the quantity delivered of the 1st fluent material X is obtained according to predetermined pump capacity, can get involved flowmeter etc. at the upstream side of this pipeline type mixing arrangement 1 and measure.In addition,, suitably set or the rotating speed of the helical blade 14s that control is produced by device for revolving and driving 15, or suitably design the size shape, pipeline volume etc. of helical blade 14s corresponding to the quantity delivered of the 1st fluent material.
In the pipeline type mixing arrangement 1 that constitutes like this, can will supply in the rectified action that produces by helical blade 14s and mix with the 2nd fluent material Y after the 1st fluent material in the mixed pipe line 12 forms the stable continuous quantitative flow.Therefore, in the present invention, can mix the 1st and the 2nd fluent material X, Y in stable ratio.In utilizing the pipeline type mixer of the present invention of this rectified action, even, also can offset its pulsation, continuous and quantitativeization by helical blade particularly in the occasion of supplying with the 1st fluent material X by interrupted feedwaies such as piston pumps.
The 1st fluent material X desilt soil cement of this 1st mixer example also can be earth classes such as pulpous state coal ash or iron and steel slag outward, the 2nd fluent material Y dewaters outside the mud lime curing agent, also can be the material of mixed processing such as blowing agent, coal ash, foam beads pellet, flowing agent, water-repelling agent to the earth class.
For example, send the earth class of supply, add curing agent etc. as the 2nd fluent material and mix, can make to solidify and handle soil as the 1st fluent material X by pump pressure.As the curing agent of this occasion etc., in this 1st mixer example, be that powder body shape still is that pulpous state is all applicable.But, because powder shape curing materials is along with one supply of calming the anger, so, as this example, the occasion of exhaust apparatus is not set at mixed pipe line 12, become the mixed air pressure that air is blended into mixture and send.In this occasion, the force feed of sending mixture towards discharge portion 12e is pressed in the air fed pressure that applies powder body curing agent on the supply pressure of earth class.On the other hand, in the occasion of adding the pulpous state curing agent, do not become mixed air pressure and send.In this occasion, the force feed that mixture is passed out to discharge portion 12e presses the supply pressure by the earth class to realize.
(the 2nd mixer example)
Though as the 1st example like that mixed pipe line 12 for straight tube, horizontal arrangement, from the occasion of open-ended discharge or not shown but in fact mixed pipe line be straight tube, horizontal arrangement, exist the occasion etc. of discharge portion such in the bottom surface, when part or all of stirring vane 14m downstream is positioned at the downside of the part corresponding with helical blade 14s and stirring vane 14m, since mixture to send resistance little, so, material is difficult for being filled to and helical blade 14s and the corresponding part of stirring vane 14m, and imagination can not be carried out the occasion of mixing in desired ratio.
The part corresponding with helical blade 14s mixed pipe line 12 and stirring vane 14m the 2nd example shown in Figure 5 is straight tube, horizontal arrangement, but make the part bending of stirring vane 14m downstream, the upside ground that discharge portion 12e is positioned at the part corresponding with helical blade 14s and stirring vane 14m constitutes.By adopting this formation, even mixed pipe line 12 is straight tube, horizontal arrangement, the resistance of sending that stirs the mixture also increases, and fluent material is filled to the part of helical blade 14s and stirring vane 14m correspondence, can carry out mixing really and fully.In addition, when existence stir the mixture send resistance the time owing to can carry out the discharge of stable amount, so, be easy to carry out the buret reason.
(the 3rd mixer example)
As shown in Figure 6,, make pipe 2 integral inclinations with becoming upside, also can increase the resistance of sending of mixing, material is full of mixes part by making the downstream though mixed pipe line 12 is a straight tube.In graphic form, bottom in the end of downstream side of mixed pipe line 12 is provided with discharge portion (outlet) 12e, but this discharge portion 12e is owing to the upside that is positioned at the part corresponding with helical blade 14s and stirring vane 14m, so the resistance increase this point of sending of mixture does not change.In addition, example only shown in Figure 6 makes the bending of upstream side bend in the horizontal direction, but also can adopt same formation in other example.
(the 4th mixer example)
Though not shown, even mixed pipe line is a straight tube,, make the mixture overflow, thereby the resistance of sending of mixture is increased by discharge portion 12e being set on its end of downstream side top, material is full of mixes part.
(the 5th mixer example)
On the other hand, Fig. 7 illustrates the form of implementation that is fit to respect to supply with the occasion of the 1st fluent material X in the mixed pipe line 12 with non-force feed state.In the pipeline type mixing arrangement example of the 2nd form of implementation, mixed pipe line 12 is a straight tube-like, on the upper wall of the position corresponding, be communicated with and be formed for falling supply unit (supply port) 12i that supplies with the 1st fluent material X with helical blade 14s formation part, be communicated with hopper 12h with respect to this supply unit by quantitative feed device (being rotary feed appliance among the figure) 12r, this point is different with other example.Other formation is identical with above-mentioned example basically.
In this pipeline type mixing arrangement, the 1st fluent material X that is stored in hopper 12h is told by quantitative feed device 12r, falls by supply unit 12i to supply in the mixed pipe line 12.The 1st fluent material X that supplies with is used as continuous and quantitative stream by the release of helical blade 14s and releases discharge portion 12e side.The 1st fluent material of releasing is after the upstream side of jet 14a prepares stirring by the stirring vane 14m that is subjected to turning round driving, with the 2nd fluent material Y interflow of supplying with from jet 14a metered injection, these the 1st fluent materials and the 2nd fluent material are mixed by the stirring vane 14m that is driven by revolution in position and its downstream of jet 14a, and this stirs the mixture and discharges by discharge portion 12e.
Like this, in the occasion of supplying with the 1st fluent material X by non-force feed state, the released amount of the unit interval of being realized by helical blade 14s is during less than the quantity delivered of the unit interval of the 1st fluent material X, can not reliablely and stablely the 1st fluent material X that supplies be sent to the downstream part of helical blade 14s, can not be full of material in this part, be difficult to mix in stable ratio.Therefore, the released amount of the unit interval of preferably being undertaken by helical blade 14s becomes the quantity delivered of the unit interval that is not less than the 1st fluent material X.Like this, can often be full of material in the downstream of helical blade 14s.In this occasion, the composite material of the released amount of being realized by helical blade 14s positively is discharged from from this mixing arrangement.
(the 6th mixer example)
In addition, in the present invention, as shown in Figure 8, also can supply in the mixed pipe line 12 from the supply port 14d that is arranged at separately on the shaft component 14 for the 1st fluent material X.In this occasion, shaft component 14 is made of bimetallic tube (or also can be 2 and tubulation), makes outlet 14a, the 14d opening of each stream in the shaft component outside, and a side as the 1st fluent material X usefulness, is used the opposing party as the 2nd fluent material Y.In this occasion, for example supply with mixing water and muddy water, earth from upstream side, simultaneously, supply with powder body or pulpous state curing agent from the downstream, handle soil thereby can make the pulpous state curing agent or solidify.
(the thin portion of mixer constitutes)
As described at the item of the example of the 1st mixer like that, send by pump pressure and to supply with the pulpous state material, supply with the occasion of powder body calming the anger, when not having exhaust apparatus, become mixed air pressure and send.In this occasion, because air is easy to produce Volume Changes, so, also imagine the occasion that can not transfer smoothly.In this occasion, like that, the top that is preferably in the powder body supply downstream, position of mixed pipe line 12 is provided with exhaust apparatus shown in the 3rd and the 4th example.In illustrated example, at the predetermined position of mixed pipe line 12 concave space 12s is set, be communicated with exhaust outlet 12d on the top of this concave space 12s, exhaust apparatus is set thus.On the other hand, supply with the occasion of curing agent etc. pressing the pulpous state attitude, do not need exhaust apparatus.
In addition, supply with in the form of the 1st fluent material X at force feed, the rectification that exists helical blade 14s to produce subtracts the gesture effect, for this reason, also imagines the occasion that the impetus weakens, can not discharge smoothly of sending of mixture.Therefore, such as shown in Figure 4 and Figure 5, the downstream that is preferably in the stirring vane 14m of shaft component 14 is provided with and promotes the boosting helical blade 14b that send of mixture towards above-mentioned downstream discharge portion.In the example of Fig. 6～8, the helical blade 14r that is arranged at the stirring vane 14m downstream of shaft component 14 does not have above-mentioned booster action.This is owing to become rightabout with the helical blade 14s of upstream or the transfer direction of boosting helical blade 14b, be used for not making the mixture of releasing successively by stirring vane it to be pushed back, make it successfully drop into outlet by the last ground of the discharge portion 12e of mixed pipe line 12 bottoms.
In addition, in pipeline type mixer of the present invention,, in the shaft component gyratory directions front side of the 2nd material supply port 14a of shaft component cover member 14c is set and also is preferred form as Fig. 3～as shown in Figure 9.This cover member 14c is along with shaft component 14 turns round while pushing the stirring thing open, so the normal supply space (cavity) that forms the 2nd fluent material passes out to this space from supply port 14a with the 2nd fluent material in the 2nd material supply port 14a position.Therefore, can reliably the 2nd fluent material be disperseed to supply in the 1st fluent material smoothly.Fig. 9 (a) illustrates contrastively with (b) and transfers the occasion that there are 90 ° of different states mutually in the angle, and both formations are identical.
Stirring vane 14m of the present invention is as Fig. 9 describes in detail, constitute by the multifunctional vane m2 with stirring action and blending objects handover effect and single functional leaf m1 of only having a stirring action, preferably get involved the form of the alternate configurations of 1 single functional leaf m1 every 1 or 2 multifunctional vane m2 along the hand of spiral that with shaft component 14 is the center.In illustrated example, multifunctional vane m2 is with respect to the platysome that tilts by predetermined angle with the face of axis quadrature, single on the other hand functional leaf m1 become with perpendicular to the parallel platysome of the face of axis.By adopting alternate configurations, can not damage handover and idiocratically improve Combination.
Multifunctional vane m2 perhaps preferably considers to form the impeller shape (curved surface is tabular) of the part that cuts spiral, but in fact clip when configuration axle when forming tabular as shown in the figure like that, difference according to the earth position contacting, the direction that moves of earth changes, mix stirring property and improve more, so more satisfactory.Promptly, as shown in Figure 10, at the A point and the B point that are on the radius of gyration, be created in A point towards the locomotivity P1 of foreign side, at B point produce the inwardly locomotivity P2 of side with the release power P of right angle effect along flat multi-functional leaf surface along gyratory directions, this increases mixing effect.
But supply pressure that pipeline type mixer of the present invention can only be adjusted the 1st fluent material by either party's stirring vane etc. works it.
In addition, the phase intervals that stirring vane 14m of the present invention separates 90 degree or 60 degree along the hand of spiral that with shaft component 14 is the center dispose when a plurality of, can carry out more effective mixing.
In addition, the present inventor learns that according to the research and development result now the combination of the formation of following helical blade 14s and stirring vane 14m and operation condition is very suitable.
(1) number of turns of helical blade: 1～3 (sheet)
(2) pitch of helical blade (SP): 0.4～0.8 position of the diameter of mixing tube
(3) configuration of stirring vane: coiled arrangement
(4) quantity of stirring vane: every pitch (MP) is pressed 4～6 interval, 5～15 pitches
The rotating speed of the shaft component when (5) moving: 150～200/ π d (rpm)
Wherein, d is the diameter of helical blade and stirring vane.
(6) the material flow velocity v:10～50m/min in the mixed pipe line
(supply port of shaft component is formed a plurality of examples)
On the other hand, in pipeline type mixing arrangement of the present invention, feedway more than 3 is set, constitutes by the material more than 2 kinds or 3 kinds being supplied in the mixed pipe line than the more path of above-mentioned example at 1 pipeline type mixing arrangement.
Specifically, as Figure 11 and as shown in Figure 12, will the position corresponding obtain longlyer, a plurality of supply ports are set at the position corresponding with the stirring vane 14m of shaft component 14 with separating predetermined space with stirring vane 14m.Example shown in Figure 11 is with the above-mentioned the 2nd routine modification, and example shown in Figure 12 is appended the supply port 14a of 1 shaft component with the above-mentioned the 3rd routine modification, and basic comprising as described above.But in these examples 40,50, the end of downstream side of shaft component 14 connects and exports to outside the mixed pipe line 12, and simultaneously, the 2nd material supply port 14a in the shaft component 14 and the part between the 2nd material supply port 14a are cut off by not shown obstruction component.Like this, add the material Y1 that mixes in front as supplying with from the upstream-side-end of shaft component 14, then it supplies in the mixed pipe line 12 from upstream side supply port 14a, is mixed with the 1st fluent material X by the stirring vane 14m that is positioned between upstream side and downstream supply port 14a, 14a.In addition, as supplying with from the end of downstream side of shaft component 14 with adding the material Y2 that mixes afterwards, then it supplies in the mixed pipe line 12 from downstream supply port 14a, by the stirring vane 14m and the 1st fluent material X mixing that has mixed material Y1 in the downstream that is positioned at downstream supply port 14a.
In this occasion, can be identical from the 2nd material supply port 14a material Y1 that supplies with and the material Y2 that supplies with from the downstream supply port, also can be different.In addition, also can further increase the supply port number of shaft component 14,, shaft component 14 be formed double-deck above multilayer pipe structure, form the feed path (not shown) of fluent material by the gap in the pipeline and between pipeline in this occasion.
(examples of a plurality of pipeline type mixers of connecting)
Pipeline type mixer of the present invention is as the part setting of material transfer pipeline, thereby in the material course of conveying, can carry out adding mixing of material (the 2nd fluent material) with other, adding material is a kind of occasion or the occasion of supplying with multiple interpolation material by shared pipeline etc., though also can 1 pipeline type mixer only be set at 1 strip transmission line, but in the occasion of add mixing multiple or of the same race interpolation material stage by stage etc., also can be directly or by other device and pipeline a plurality of pipeline type mixing arrangements of connecting indirectly, in each pipeline type mixing arrangement, add the mixing of appending of material successively.
This particular instantiation is for Figure 13～Figure 15.Example shown in Figure 13 is by the connect mixer 10,10 of above-mentioned the 1st example of carrier pipe T, and relative the 1st fluent material X mixes the 2nd, the 3rd fluent material Y1, Y2 successively.In addition, example shown in Figure 14 has the upstream side mixer 10A of the discharge portion 12e of lower opening in the upstream side configuration, the downstream mixer 10B of the supply port 12i of opening above the downstream configuration has, directly connect the downward outlet 12e of upstream side mixer 10A and the upwards supply port 12i of downstream mixer 10B, two mixer 10A, 10B is integrated.The occasion that has a plurality of mixing portion so also is contained in pipeline mixer of the present invention.In this example shown in Figure 14, handover source and the position relation of transferring the destination corresponding to material, can adopt the mixer 10B with relative the opposing party of mixer 10A of a side is that center steering disposes arbitrarily angledly with the connecting portion, also can form and carry out the U word configuration that turning back of material transferred for example as shown in Figure 15.
In these concrete examples, can certainly use above-mentioned other pipeline type mixer (not shown).
, the manufacture method of above-mentioned lightweight curing materials is to use this series connection form, but the series connection form of pipeline mixer of the present invention is not limited to the manufacture method of above-mentioned lightweight curing materials.For example also can be used for supplying with the lighting materials at the 1st pipeline type mixer 4 on the contrary with the manufacture method of above-mentioned lightweight curing materials, in the form of the 2nd pipeline type mixer 5 mixed curing agents.
