Coal txiv tsawb screenscreen thiab fastening txoj kev screen nto yog qhov tseem ceeb ntawm qhov screen. Cov kev cai yooj yim rau lub vijtsam saum npoo yog: lub zog txaus, thaj tsam zoo tshaj plaws (qhov piv ntawm tag nrho cheeb tsam ntawm lub vijtsam mus rau tag nrho cov cheeb tsam ntawm lub vijtsam), lub vijtsam tsis yooj yim rau ntsaws, thiab lub sijhawm kom tau raws li lub vijtsam hauv kev txav ntawm cov khoom siv ntau dua. Cov kev xav tau yav dhau los cuam tshuam rau kev ntseeg siab thiab kev pabcuam lub neej ntawm qhov screen, thiab peb qhov kev xav tau tom kawg yog cuam tshuam nrog kev ua haujlwm ntawm lub vijtsam. Feem ntau siv cov tshuaj ntsuam saum npoo ntawm lub phaj, tshuaj ntsuam mesh, slit screen phaj thiab mesh silk ntaub plaub. Thawj ob feem ntau yog siv hauv kev faib tawm thiab tshuaj ntsuam xyuas; Ob lub tom kawg yog siv rau hauv lub cev qhuav dej, desliming thiab desliming media. Kev xaiv kom raug ntawm qhov screen nto, tuaj yeem txhim kho qhov kev tshuaj ntsuam xyuas thiab kev ntseeg tau ntawm kev ua haujlwm, thiaj li ua si lub peev xwm ntawm lub vijtsam. Txhawm rau kom ntseeg tau qhov kev ntseeg tau ntawm kev ua haujlwm ntawm qhov screen saum npoo, txoj kev kho qhov screen saum npoo kuj muaj kev cuam tshuam zoo, uas yog tshwj xeeb tshaj yog nyob rau ntawm qhov screen nto ua los ntawm cov hlau hlau lossis hlau strips. Vim tias yog lub vijtsam ruaj khov ntau dua: sieve vibration, screen mesh yuav tsim kev co hauv zos, kom tag nrho cov deflection ntawm lub vijtsam xaim ntau lawm chaw ua haujlwm, hnyav ua rau tawg ntawm lub vijtsam xaim. Feem ntau cov hlau hlau tsuas tuaj yeem tiv taus 1 ~ 2 lab lub sijhawm ntawm kev rov kho dua, piv txwv tias qhov zaus ntawm kev khoov deformation ntawm steel hlau yog sib npaug rau qhov zaus ntawm kev vibration ntawm lub npov npo vim kev ruaj khov, cov hlau xaim ntev npaum li kev ua haujlwm 2000min, tuaj yeem ncav cuag qhov qaug zog. Bar screen nto Ib qhov chaw bar yog tsim los ntawm shafts los yog tuav nyob rau hauv parallel thiab nruj nrog ib leeg. Qhov loj ntawm qhov screen yog txiav txim siab los ntawm qhov dav ntawm qhov sib txawv ntawm cov tuav. Bar cov ntxaij vab tshaus feem ntau yog sib sau ua ke ntawm qhov chaw ua haujlwm los ntawm cov khoom siv hauv zos, yog li cov duab ntawm lub bar yuav txawv. Lub bar npo saum npoo rau kev tshuaj xyuas cov ntaub ntawv ntau yog qee zaum tsim los ntawm cov kab hlau welded uas hloov tau manganese steel daim hlau raug teeb tsa los tiv thaiv hnav.coal txiv tsawb screensmuaj qee zaum muab cov ntxaij vab tshaus uas muaj cov kab hlau ntxig rau ntawm kev txhawb nqa tshwj xeeb. Cov kabmob muaj ib lub raj hlau thiab lub tes tsho npog ua los ntawm cov roj hmab tshwj xeeb. Flange qhov kev txhawb nqa rau ntawm ntug ntawm qhov screen ncej. Nyob rau sab ntawm lub bracket yog ob kab ntawm lub qhov, thiab cov hlau tuav uas ua rau lub vijtsam yog ntxig rau hauv cov qhov no.
Thib ob, phaj npo npo npo phaj yog cov khoom siv tshuaj ntsuam xyuas, feem ntau yog siv hauv kev tshuaj xyuas cov khoom loj. Raws li kev paub dhau los ntawm cov neeg siv khoom siv dav dav, lub sieve phaj yuav tsum tau siv rau kev faib tawm ntawm qhov loj ntawm ntau tshaj 25mm, kom lub neej ntawm lub vijtsam nto ntev dua thiab kev tshuaj ntsuam xyuas tsis cuam tshuam. Qhov qhib tus nqi ntawm qhov screen yog feem ntau txog 40%. Cov khoom siv ntawm sieve phaj feem ntau yog A3 thiab 16Mn, 16MnCr steel phaj, steel phaj thickness feem ntau yog siv 6 hli, raws li kev ua haujlwm sib txawv tuaj yeem ua kom tuab lossis nyias. Kev ua ntawm sieve phaj tuaj yeem ua tiav los ntawm drilling lossis xuas nrig ntaus. Feem ntau siv cov duab ntawm lub sieve yog puag ncig, thiab qee zaum nws kuj yog duab plaub. Thaum siv cov duab plaub, sab ntev yuav tsum ua raws li cov kev taw qhia ntawm cov khoom txav, thiab cov txheej txheem ua tsuas yog xuas nrig ntaus. Txhawm rau kom tsis txhob muaj qhov thaiv ntawm lub vijtsam, lub vijtsam tuaj yeem ua tiav rau hauv lub khob loj hauv qab, kom lub vijtsam maj mam nthuav tawm ntawm qhov nkag mus rau qhov hluav taws xob ntawm cov khoom, uas yog qhov zoo rau cov khoom siv los ntawm kev tshuaj ntsuam. Rau perforated sieve daim hlau, cov txheej txheem no nthuav dav tuaj yeem tshwm sim. Raws li ib txwm muaj, xuas nrig ntaus yog yooj yim dua li drilling, yog li thaum muaj xwm txheej, xuas nrig ntaus yuav tsum tau siv. Circular sieves yuav luag ib txwm nyob rau hauv ib lub pob zeb diamond zoo li yuav ua rau lub sieve phaj muaj zog txaus thiab qhib kom ntau li ntau tau.
Peb, qhov zoo tshaj plaws ntawm Coal banana screen woven screen mesh yog qhov qhib tus nqi loj, mus txog 70% ntawm tag nrho cov cheeb tsam ntawm lub vijtsam, tab sis piv nrog lub vijtsam phaj, qhov ceev ceev tsis zoo, kev pab cuam lub neej luv luv, yog li nws feem ntau tsuas yog siv hauv kev faib tawm ntawm qhov loj me me. Nws feem ntau yog siv rau hauv kev npaj cov nroj tsuag rau thee tshauv qib nrog particle loj tsawg dua 13 hli. Cov khoom siv feem ntau ntawm kev tshuaj ntsuam yog cov pa roj carbon tsawg, nws tsuas yog haum rau hnav cov khoom siv tsawg. A0 steel yog siv nyob rau hauv ntau lub hoobkas hauv peb lub teb chaws, thiab qee zaum txhuas hlau sieve. Cov pa roj carbon siab lossis hlau alloy tuaj yeem siv tau yog tias cov khoom siv hnav ntau dua. Lub vijtsam ua los ntawm cov hlau tsis muaj steel thiab 65M steel hlau, txawm hais tias tus nqi siab dua, tab sis kev pabcuam lub neej tuaj yeem txuas ntxiv ob peb zaug, yog li nws muaj txiaj ntsig zoo hauv kev lag luam. Feem ntau ntawm cov mesh qhov yog square, feem ntau woven. Qhov tsis zoo ntawm woven npo yog tias qhov saum npoo tsis du, cuam tshuam cov txheeb ze txav ntawm cov khoom ntawm qhov screen, qhov tuab ntawm lub sieve, qhov teeb meem tseem ceeb dua. Txhawm rau kov yeej qhov tsis txaus no, siv lub corrugated screen hlau. Txhawm rau txo qhov kev sib txuas ntawm qhov screen protrusion, lub vijtsam tuaj yeem flattened ntawm no, txhawm rau txo qhov tsis kam ntawm cov khoom raws li qhov screen nto, tab sis kuj tseem txuas ntxiv lub neej ntawm lub vijtsam. Kev siv cov splint tshwj xeeb ntawm ob sab ntawm lub vijtsam thav duab los ntawm kev sib tw rub kom nruj, thiab tom qab ntawd siv bolts los kho qhov splint ntawm lub npov npo. Txhawm rau ua kom cov khoom siv tshuaj ntsuam tuaj yeem sib npaug ntawm qhov screen, feem ntau cov plaub hau sieve rau hauv ib lub koov. Lub vijtsam nro tuaj yeem txhim kho nws lub neej kev pabcuam, yog li kev ua haujlwm yuav tsum tau ua tib zoo saib xyuas nws qhov nruj.
Plaub, tsis yog -hlau npo npo
Rubber screen muaj qhov zoo ntawm kev hnav tsis kam, lub teeb yuag thiab tsis tshua muaj suab nrov, thiab tau ua tiav cov txiaj ntsig zoo hauv kev siv tswv yim. Cov roj hmab npo saum npoo tuaj yeem tsim ncaj qha los ntawm roj hmab. Lub vijtsam tuaj yeem yog square, puag ncig lossis sewn, lossis nws tuaj yeem muaj lub plawv ua los ntawm steel bar, thiab steel bar yog coated nrog roj hmab. Rubber screen nto nws tus kheej- ntxuav cov nyhuv yog qhov zoo tshaj plaws, cov teb chaws txawv teb chaws muaj qhov qhib siab dua ntawm cov khoom, rau cov ntaub ntawv noo noo ntau dua, yuav tsum yog lub ntsej muag zoo tagnrho, tab sis tam sim no cov khoom lag luam hauv tsev muaj qhov qhib qhov teeb meem, thiab lub sieve yog ntau tshaj 13 hli.
(2) amino ester thiab polyurethane kua nplaum npo phaj ammonia thiab polyurethane yog cov tshiab siab -zoo hnav- cov ntaub ntawv resistant, haum rau kev tsim cov tshuaj ntsuam saum npoo. Nyob rau sab nraud ntawm steel sieve phaj npog nrog ammonia Taforga hom 2 npo saum npoo thiab ntxiv dag zog nrog steel hlau txheej Tafortai hom ammonia npo saum npoo, tau nrov hauv kev tsim khoom, muaj kev hnav zoo, tsis tshua muaj suab nrov, tuaj yeem khaws cia hauv huab cua qhib, thiab lwm yam.
