1. Dab tsi yog Lub Tsheb Thauj Khoom Thauj Khoom?
Lub tsheb thauj khoom loj loj - technically hu ua pneumatic bulk khoom thauj tsheb - yog lub tsheb tshwj xeeb kev lag luam tsim los rau kev thauj cov khoom qhuav, pulverized hauv ntau. Cov ntaub ntawv no feem ntau suav nrog:
Portland cement
Fly tshauv (los ntawm cov chaw tsim hluav taws xob hluav taws xob hluav taws xob)
Txiv qaub hmoov
Mineral hmoov (xws li barite, bentonite)
Cov hmoov tshuaj (piv txwv li, calcium carbonate)
Cov khoom lag luam (piv txwv li, hmoov nplej, hmoov txhuv nplej siab)
Qhov loj me ntawm cov ntaub ntawv no feem ntau tsawg dua lossis sib npaug li 0.1 hli. Lub tanker tau dav siv hauv kev tsim kho, hluav taws xob tsim hluav taws xob, kev ua tshuaj lom neeg, kev ua liaj ua teb, thiab metallurgical industries, tsim ib qho tseem ceeb txuas hauv kev lag luam niaj hnub no.
Txoj Cai Kev Ua Haujlwm Core: Fluidization
Lub engineering zais cia tom qab cov hmoov tanker yog rooted nyob rau hauv lub cev tshwm sim ntawm fluidization.
Thaum compressed cua yog txhaj los ntawm hauv qab ntawm lub tank mus rau hauv ib lub txaj ntawm hmoov hais, thiab cov huab cua tshaj tawm tshaj ib tug tej yam pib - hu ua qhov tsawg tshaj plaws fluidization tshaj tawm (kwv yees li 0.015 m / s rau cement) - lub zog rub los ntawm cov huab cua counterbalances downward particles. Hauv qhov no:
Cov hmoov txaj nthuav dav hauv ntim.
Cov khoom ua randomly suspended thiab heev mobile.
Cov khoom coj tus cwj pwm zoo li cov kua dej - nws tuaj yeem ntws los ntawm qhov siab dua mus rau qhov siab qis, tuav lub kab rov tav sab sauv, thiab txawm tias "spurt" tawm ntawm qhov qhib txiav mus rau sab ntawm lub nkoj.
Hmoov tankers siv lub hauv paus ntsiab lus no kom tso tawm lawv cov khoom thauj kom zoo thiab ua tiav los ntawm cov kav dej, tsis tas yuav siv cov tshuab conveyors lossis kev tuav tuav.
Dab tsi yog qhov feem ntau ua rau txo qis tus nqi tso tawm hauv cov hmoov ntim ntau, thiab lawv tuaj yeem kuaj tau li cas?
Feem ntau ua rau yog compressor efficiency poob thiab fluidizing ntaub thaiv, accounting rau ntau tshaj 70% ntawm cov neeg mob. Compressor hnav lossis lim lim kom txo cov cua xa tawm - yog tias lub tank siab tshaj 12 feeb (ib txwm yog 6-8), lub compressor xav tau kev tshuaj xyuas. Fluidizing npuag clogged nrog cov hmoov zoo tiv thaiv tsis sib xws aeration; tshuaj xyuas cov ntaub nto rau caking los yog kua muag tom qab unloading. Kev txwv cov kav dej los ntawm cov khoom tsim los yog kinked hoses tuaj yeem ua rau muaj teeb meem, qhia los ntawm qhov sib txawv siab tshaj 0.05 MPa ntawm lub qhov hluav taws xob tank thiab silo. Kev saib xyuas tsis tu ncua - roj hloov txhua 200 teev thiab hloov ntaub txhua 6–12 lub hlis - tiv thaiv cov teeb meem kev ua haujlwm feem ntau.
Summary of Bulk Powder Tanker
Lub tsheb thauj khoom loj loj yog lub tsheb thauj khoom tshwj xeeb pneumatic uas siv cov cua compressed kom fluidize cov ntaub ntawv qhuav xws li cov cement thiab ya tshauv, ua kom muaj txiaj ntsig zoo, plua plav- tso tawm dawb los ntawm cov kav dej. Nws cov txiaj ntsig tseem ceeb ntawm kev thauj mus los hauv hnab ntim khoom suav nrog kev ua haujlwm qis thiab cov nqi ntim khoom, cov khoom siv tsawg tsawg (<0.5%), and superior moisture protection. Regular maintenance of the air compressor and fluidizing fabric is essential to maintain optimal discharge performance and extend service life.
