Kev ceev faj rau masonry ntawm rotary kiln
Kev ceev faj rau masonry ntawm rotary kiln
Kev khiav hauj lwm tus nqi ntawm lub teb kiln (cement kiln) muaj kev sib raug zoo nrog rau qhov zoo ntawm refractory cib masonry. Nws yuav tsum tau ua tib zoo tsim nyob rau hauv nruj raws li cov kev cai ntawm refractory cib masonry. Cov kev cai tshwj xeeb yog raws li hauv qab no:
1. Lub cellar daim tawv nqaij sib txuas nrog lub cib hauv ob sab phlu yuav tsum tau muab ntxuav ua ntej kev tsim kho, tshwj xeeb tshaj yog qhov chaw uas cov square ntoo muab tso rau yuav tsum tiaj tus li sai tau.
2. Tighten lub cib nyob rau hauv kab rov tav thiab ntsug cov lus qhia nrog ib tug ntsia hlau thiab square ntoo; Tom qab txiav txim siab qhov yuav tsum tau hloov, siv cov ntsia hlau thiab square ntoo kom nruj rau qhov seem.
3. Thaum tshem cov cib qub los ntawm lub trench, xyuam xim rau kev tiv thaiv lub cib hauv ob sab phlu kom tsis txhob zawv zawg ntawm cov cib seem. Tom qab kev tsis lees paub, lub phaj me me yog welded rau lub tog raj kheej kom tiv thaiv lub cib hauv ob sab phlu los ntawm zawv zawg.
4. Ua ntej lub refractory bricks yog tsim, lub plhaub ntawm lub revolving cellar yuav tsum tau kom huv si thiab ua tib zoo tshuaj xyuas kom huv si cellar.
5. Thaum lub tsev, txawm li cas los xij txoj kev ntawm masonry yog saws, lub masonry yuav tsum tau ua nruj me ntsis raws li lub hauv paus, thiab nws yog nruj me ntsis txwv tsis pub tsim tsis tau nteg kab. Npaj cov kab ua ntej tso cov cib refractory: lub hauv paus kab ntawm lub cellar yuav tsum tau muab tso rau raws li ib ncig ntawm 1.5m, thiab txhua kab yuav tsum parallel mus rau lub axis ntawm cellar; cov kab siv ncig yuav tsum muab tso rau txhua 10m, thiab cov kab ncig yuav tsum zoo ib yam. Yuav tsum ua tib yam rau ib leeg thiab perpendicular mus rau axis ntawm lub cellar.
6. Cov txheej txheem tseem ceeb ntawm kev cib hauv lub cellar yog: lub cib hauv ob sab phlu yog ze rau ntawm lub cellar plhaub, cov cib thiab cov cib yuav tsum nruj, cov pob qij txha yuav tsum ncaj, kev sib tshuam yuav tsum yog qhov tseeb, cov cib yuav tsum tau muab xauv kom ruaj, nyob rau hauv ib qho chaw zoo, tsis sagging, thiab tsis ntog. Nyob rau hauv luv luv, nws yog tsim nyog los xyuas kom meej tias cov refractory bricks thiab cellar lub cev muaj ib tug txhim khu kev qha concentricity thaum lub sij hawm cellar ua hauj lwm, thiab cov kev nyuaj siab ntawm bricks yuav tsum tau muab sib npaug zos rau tag nrho cov cellar hauv ob sab phlu thiab ntawm txhua lub cib.
7. Bricklaying txoj kev yog muab faib ua ob pawg: nplhaib masonry thiab staggered masonry. Cov cellars tshiab thiab lub tog raj kheej tau tswj tau zoo thiab qhov deformation tsis loj. Lub nplhaib masonry feem ntau yog siv; Lub tog raj kheej deformation yog qhov hnyav dua thiab cov cib siv tsis zoo. Nyob rau hauv lub cellar, staggered masonry txoj kev yuav siv tau nyob rau hauv lub siab alumina cib thiab cov av nplaum cib.
8. Thaum lub nplhaib-txheej, lub nplhaib-rau-lub ntiaj teb sib txawv yog tso cai rau 2 hli ib ‘meter’, thiab qhov ntev ntawm ib qho kev tsim kho tau tso cai rau 8 hli. Thaum staggered, qhov ntsug sib txawv ntawm ib lub ‘meter’ raug tso cai yog 2 hli, tab sis qhov siab tshaj plaws tso cai ntev ntawm tag nrho lub nplhaib yog 10 hli.
9. Lub cib kawg ntawm txhua lub voj voog (tshwj tsis yog lub voj voog kawg) raug thawb los ntawm ib sab ntawm lub cib hauv ob sab phlu (nyob rau hauv cov kev taw qhia ntawm lub axis ntawm lub revolving cellar) kom tiav tag nrho lub voj voog ntawm masonry, thiab xyuam xim rau kev kho qhov chaw. cib hom kom deb li deb tau tsis txhob siv nws. Qhuav-ntev steel daim hlau feem ntau yog 1-1.2 hli, thiab qhov dav ntawm cov hlau phaj yuav tsum yog li 10 hli me dua qhov dav ntawm lub cib.
10. Tom qab cov cib refractory tau tsim, tag nrho cov hauv ob sab phlu cib yuav tsum tau muab ntxuav thiab fastened comprehensively. Nws tsis pom zoo kom hloov lub cellar tom qab fastening tiav. Nws yuav tsum tau ignited nyob rau hauv lub sij hawm thiab ci raws li lub ziab cellar nkhaus.
