Lub tshuab yog tsim los ntawm lub hauv paus, ib pawg kis tau tus mob thiab lub tog raj kheej sib xyaw, lub hauv paus yog siv los kho cov pab pawg kis tau tus mob, cov pab pawg kis tau tsav lub tog raj kheej sib xyaw kom tig, cov ntawv sib xyaw yog muab nrog ntau qhov sib xyaw ua ntej thiab ib qho Feem ntau ntawm thawj cov khoom sib xyaw, ib sab ntawm thawj cov khoom sib xyaw yog npaj nyob ib ncig ntawm cov phab ntsa sab hauv ntawm lub tog raj kheej sib tov, thiab cov kev taw qhia kev sib hloov ntawm cov khoom sib tov thib ob, thiab cov naj npawb ntawm kev sib hloov tsis zoo ib yam. Cov qauv siv hluav taws xob ua kom muaj ntau yam ntawm cov ntaub ntawv nyoos los swb rau ntawm thawj daim ntawv sib xyaw thiab daim ntawv sib xyaw thib ob kom tsis txhob rhuav tshem cov nplej ntawm cov khoom siv raw thaum sib tov, thiab tsim cov vortex me me los yob cov ntaub ntawv thiab sib npaug ntawm cov khoom sib xyaw los ntawm noj kom zoo dua ntawm qhov sib txawv ntawm kev sib hloov ntawm ob daim ntawv sib xyaw thiab qhov sib txawv ntawm cov kev sib hloov.
Cov khoom sib xyaw ua ke yog cov khoom sib xyaw ntau dua, cov khoom sib xyaw ua ke raws li txoj cai ua haujlwm, tuaj yeem muab faib ua ob pawg: nws tus kheej poob thiab yuam hom.
(1) Tus kheej ntog pob zeb tov khoom yog tsim rau kev sib xyaw cov pob zeb yas.
(2) Qhov sib xyaw ua ke ntawm cov khoom sib xyaw ua ke muaj zog dua li ntawm qhov sib tov nws tus kheej, thiab cov pob zeb qhuav qhuav thiab lub teeb sib xyaw ua ke sib xyaw ncaj qha. Noj cov khoom sib tov yuam ua piv txwv, lub hauv paus ntsiab lus thiab kev txhim kho ntawm lub tov khoom raug nthuav tawm.
Qhov tseem ceeb ntawm kev sib xyaw ua ke
Kunset av tov khoom yog lub tshuab tshwj xeeb rau kev npaj pob zeb los ntawm kev sib xyaw ua vaj tse sib xyaw ua ke raws li kev sib xyaw ntawm cov cement, xuab zeb, gravel (tag nrho) thiab dej. Lub koom haum feem ntau ntseeg hais tias lub luag haujlwm tseem ceeb ntawm lub pob zeb sib tov yog: ua kom cov khoom sib xyaw ua ke sib npaug, kom nws sib xyaw ua ke, rhuav tshem cov cement "bunching" phenomenon thiab ua kom cov cement nyob rau saum npoo ntawm tag nrho cov ntaub qhwv, npaj txhij. rau kev sib tov tag nrho: txuas ntxiv do los txhawb cov cement hais thiab nws cov coarse aggregate tag nrho ua ke los tsim cov cement zoo tagnrho thaum cov dej ntau dhau los encapsulate cov coarse aggregate, Nws tsis yog conducive rau adhesion ntawm cement hmoov, thiab sib tov. ntawm lub tov khoom tuaj yeem faib cov nyhuv adhesion ntawm cov yeeb yaj kiab dej phem, thiaj li ua tiav lub hom phiaj ntawm homogenization ntawm cov cement sib tov.
2, lub hauv paus ntsiab lus thiab kev faib tawm ntawm cov pob zeb sib tov
Tus kheej ntog tov khoom thawj zaug tshwm sim nyob rau hauv thaum ntxov 20th caug xyoo, lub earliest nruas pob zeb tov khoom yog tsav los ntawm lub cav cav 50 xyoo tom qab, txawv discharge txoj kev rau cov yam ntxwv ntawm lub tov khoom thiab txawv kev pub mis ntawm lub tov khoom tau tawm los ntawm tus kheej-deb. tov khoom yog hais txog cov hniav sib tov tsau rau ntawm phab ntsa sab hauv ntawm lub tog raj kheej sib tov, thaum sib tov lub tog raj kheej kab rov tav, cov hniav sib tov yuav do cov sib tov nyob rau hauv qhov yooj yim ib feem nyob rau hauv qhov kev txiav txim ntawm nws tus kheej qhov hnyav, kom lub cyclic kev ua si mus txog qhov tshwm sim. ntawm symmetrical mix. Qhov kev teeb tsa ntawm tus kheej-poob qhob tov khoom yog qhov yooj yim, thiab nws feem ntau yog raws li kev sib xyaw ntawm cov yas pob zeb.
Lub pob zeb sib xyaw ua ke yog ua raws li kev sib hloov ntawm qhov sib xyaw ua ke hauv txoj haujlwm kab rov tav ntawm lub nruas sib xyaw thiab kev sib txuas ntawm caj npab, uas ua rau muaj kev txav txav xws li extrusion, shear, cuam tshuam thiab ncig axial dawb poob ntawm cov khoom sib xyaw.
Tom qab bulking los ntawm thaum ntxov 1950s, kev loj hlob sai thiab nce qib pib tshwm sim yog lub disc yuam kev sib tov. Tom qab xyoo 1870, nrog rau qhov tshwm sim ntawm cov kev sib sau tshiab, muaj ib hom tshiab ntawm kev quab yuam sib tov, uas pom tau hais tias lub tov khoom nrog ob qho tib si rau nws tus kheej poob thiab yuam kev. Cov hniav sib xyaw muaj cov yam ntxwv ntawm kev ceev me me, hnav tsis kam thiab tsis muaj zog noj. Cov hniav sib xyaw yog tam sim no nyob rau hauv lub nruas sib tov thiab koom nrog kev sib tov. Cov cement nyob rau hauv lub nruas sib tov ua ib homogeneous cement sib tov nrog ntxhib thiab nplua aggregates nyob rau hauv lub stirring ntawm cov hniav sib tov. Kev sib xyaw ua ke txuas ntxiv yog nruab nrog cov khoom sib xyaw ua ke, thiab txhua yam ntawm cov khoom siv txuas ntxiv mus thiab xa mus rau lub tov khoom raws li qhov sib piv, thiab cov av sib xyaw tsis tu ncua tawm ntawm qhov paug tawm. Lub sijhawm sib xyaw ntawm cov khoom sib tov yog luv luv, cov khoom tsim tau siab, thiab nws txoj kev loj hlob yog qhov muag pom.
Nrog rau kev loj hlob ntawm cov khoom vaj khoom tsev thiab kev tsim kho tshuab, tau muaj ntau yam tshiab ntawm cov pob zeb sib tov. Xws li chav cua sov tov khoom, supercritical ceev tov khoom, acoustic tov khoom. Lub pob zeb pob zeb tov khoom tsis sib xyaw cov hniav thiab cov pob zeb sib xyaw nrog cov sib xyaw ua ke thiab lwm yam.
3 Tov khoom siv kev ceev faj txog kev nyab xeeb
Tus neeg tsav tsheb ntawm lub pob zeb sib tov yuav tsum paub txog kev ua haujlwm thiab kev ua haujlwm ntawm cov tshuab ua haujlwm, thiab yuav tsum hnav cov khoom tiv thaiv kev ua haujlwm raws li cov cai thaum ua haujlwm. Ua ntej ua hauj lwm, xyuas seb qhov kis tau tus mob clutch thiab nres yog hloov tau thiab txhim khu kev qha, seb puas yog lub thoob nce toj hlau hlua tawg, cov khoom siv sib xyaw, rub thiab lwm qhov chaw sib kis ntawm kev tiv thaiv tsis zoo, lub cev muaj zog hauv av yog qhov zoo, paub meej tias qhov yuam kev ua ntej ua haujlwm. , yog tias muaj kev txhaum tsis tuaj yeem txuas ntxiv mus yuav tsum tau txiav tawm tam sim ntawm lub hwj chim. Tshem cov pob zeb ntawm lub nruas sib tov thiab tom qab ntawd kho nws. Lub pob zeb sib tov yuav tsum siv ob theem kev tiv thaiv. Tus neeg tsav tsheb tsis raug tso cai tawm ntawm qhov chaw ua haujlwm thaum lub sijhawm ua haujlwm tshuab. Nws yog txwv tsis pub siv hlau, spade lossis lwm yam khoom los txuas rau hauv lub tog raj kheej sib xyaw thaum lub tshuab tov ua haujlwm. Tsis muaj leej twg raug tso cai hla los yog nyob hauv qab lub hopper thaum nws tsa. Yog tias tsim nyog los kho hauv qab lub thoob, nres lub tsheb thiab txiav tawm lub zog hluav taws xob, thiab siv cov ntawv txuas kev ruaj ntseg los yog cushion tus neeg pw tsaug zog ua ntej nqa tawm. Nws yog nruj me ntsis txwv tsis pub muab tus neeg teb xov tooj lub taub hau tso rau hauv lub hopper thiab lub thav duab los xyuas qhov xwm txheej pub mis thaum lub sijhawm pub mis. Nco ntsoov saib xyuas seb qhov chaw ntawm lub pob zeb sib tov ua haujlwm li cas. Yog tias tsim nyog nkag mus rau hauv lub tog raj kheej sib xyaw rau kev ntxuav, lub zog hluav taws xob yuav tsum raug txiav, lub fuse yuav tsum raug tshem tawm, thiab lub thawv hloov yuav tsum tau muab xauv, lossis tus neeg yuav tsum tau saib xyuas nws.
