Plaub Yam Khoom Siv rau Electrostatic Spray Systems

Feem ntau cov hmoov txheej Cov tshuab hluav taws xob hluav taws xob muaj xws li plaub yam khoom siv yooj yim - cov khoom noj hopper, electrostatic hmoov txau phom, hluav taws xob hluav taws xob, thiab cov hmoov rov qab. Kev sib tham ntawm txhua daim, nws cov kev sib cuam tshuam nrog lwm cov khoom, thiab ntau yam qauv muaj yog tsim nyog kom nkag siab txog kev ua haujlwm ntawm cov txheej txheem no.

Cov hmoov yog nkag mus rau rab phom txau los ntawm cov hmoov feeder unit. Feem ntau cov hmoov uas khaws cia rau hauv chav tsev no yog fluidized los yog lub ntiajteb txawj nqus-fed rau lub twj tso kua mis rau kev thauj mus rau rab phom (s) (Daim duab 5-9). Cov txheej txheem pub noj tshiab tshiab tuaj yeem tso cov hmoov ncaj qha los ntawm lub thawv cia.

Lub twj tso kua mis feem ntau ua haujlwm raws li lub venturi, qhov twg compressed los yog yuam airflow dhau los ntawm lub twj tso kua mis, tsim ib tug siphoning nyhuv thiab nqus cov hmoov los ntawm lub feed hopper rau hauv cov hmoov hoses los yog feed tubes, raws li qhia nyob rau hauv daim duab 5-10. Cua yog generally siv los cais cov hmoov nplej kom yooj yim thauj thiab them peev xwm. Volume thiab nrawm ntawm cov hmoov ntws tuaj yeem hloov kho.

Feem ntau, cov khoom siv feeder siv huab cua, kev co, lossis cov neeg kho tshuab stirrers los pab "sib cais" cov hmoov loj. Qhov kev txiav txim no ua rau muaj kev thauj mus los yooj yim dua ntawm cov hmoov, thaum pab tswj cov ntim thiab qhov nrawm ntawm cov hmoov ntws mus rau cov phom tsuag. Kev ywj pheej tswj cov hmoov thiab cov huab cua ntim pab kom ua tiav qhov kev xav tau ntawm cov txheej txheej txheej. Cov hmoov feeder muaj peev xwm muab cov khoom txaus rau ib lossis ntau dua electrostatic tsuag phom sevral ko taw deb. Powder feeders muaj nyob rau hauv ntau qhov sib txawv, nrog rau kev xaiv nyob ntawm daim ntawv thov, tus naj npawb ntawm cov phom yuav tsum tau muab, thiab ntim cov hmoov yuav tsum tau txau rau lub sijhawm teev tseg. Generally tsim los ntawm cov ntawv hlau, lub feeder unit tuaj yeem mounted nyob ib sab, los yog txawm ua ib qho kev sib koom ua keral ib feem ntawm, rov qab unit.

Feeder units, uas siv fluidizing cua los pab txhawb nqa cov khoom siv hmoov rau lub tswv yim tshuaj tsuag. Compressed, los yog yuam, cua yog nkag mus rau ib tug huab cua plenum noobrally nyob rau hauv qab ntawm lub feeder unit. Nruab nrab ntawm huab cua plenum thiab lub cev tseem ceeb ntawm chav tsev feeder yog ib daim nyias nyias, feem ntau yog ua los ntawm cov khoom siv yas sib xyaw. Compressed cua kis tau los ntawm nws mus rau hauv lub ntsiab lub cev ntawm lub feeder unit, qhov twg hmoov cov ntaub ntawv khaws cia. Kev ua kom dej ntws tawm ntawm huab cua ua rau nqa cov khoom siv hmoov nce siab, tsim kom muaj kev ntxhov siab, lossis ua kom muaj dej, lub xeev (Daim duab 5-2). Nrog rau qhov ua kua dej no, nws muaj peev xwm tswj tau cov metering ntawm hmoov siphoned los ntawm lub feeder chav tsev los ntawm kev txuas, los yog submerged, venturi-style twj tso kua mis (saib daim duab 5-9).

Thaum lub ntiajteb txawj nqus feed-type feed units yog siv, lub lag luam muaj ib tug conical los yog funnel-shaped unit nyob rau hauv uas hmoov cov ntaub ntawv khaws cia. Cov twj tso kua mis txuas nrog rau hom feeder no feem ntau yog ntawm lub twj tso kua mis venturi. Qee zaum, kev vibration lossis mechanical stirrers yog siv los txhim kho cov hmoov siphoning los ntawm cov nyhuv venturi uas tsim los ntawm cov twj tso kua mis. Hmoov yog lub ntiajteb txawj nqus pub rau cov twj tso kua mis, thiab cov kua dej ntawm cov hmoov tsis tsim nyog. Ib zaug ntxiv, saib daim duab 5-9. Cov hmoov kuj tseem tuaj yeem xa ncaj qha los ntawm cov thawv hmoov lossis cov thawv uas siv ob lub raj zoo siphon, uas muab cov kua dej txaus hauv zos kom tso cai rau kev xa khoom zoo ib yam.

Sieving cov cuab yeej siv qee zaum ua ke nrog cov khoom noj khoom haus los tshuaj xyuas cov av, pawg hmoov, thiab lwm yam khib nyiab, thiab ua kom cov hmoov ua ntej txau. Cov sieves no tuaj yeem txuas ncaj qha mus rau lossis siab dua chav pub khoom noj kom yooj yim dua ntawm cov hmoov nplej nyob rau hauv lub voj kaw ntawm cov hmoov xa tuaj, tshuaj tsuag, thiab rov qab los (Daim duab 5-1 1).
