Wophatikiza fetereza, wotchedwanso mankhwala fetereza, ndi fetereza munali zakudya ziwiri kapena zitatu za zakudya mbewu, monga nayitrogeni, phosphorous ndi potaziyamu, apanga ndi zimachitikira mankhwala kapena kusakaniza njira;feteleza pawiri akhoza kukhala powdery kapena granular.Manyowa ophatikizika amakhala ndi zinthu zambiri zogwira ntchito, zosavuta kusungunuka m'madzi, zimawola mwachangu, ndipo zimakhala zosavuta kumera ndi mizu.Choncho, amatchedwa "feteleza wachangu".Ntchito yake ndikukwaniritsa kufunika kokwanira komanso kuchuluka kwa zakudya zosiyanasiyana m'malo osiyanasiyana opanga.
Mzere wapachaka wopangira matani 50,000 a feteleza apawiri ndi kuphatikiza zida zapamwamba.Ndalama zopangira ndi zopanda ntchito.Mzere wopangira feteleza wophatikiza ukhoza kugwiritsidwa ntchito popangira zinthu zosiyanasiyana zopangira.Pomaliza, feteleza wophatikizika wokhala ndi milingo yosiyanasiyana ndi ma formula akhoza kukonzedwa molingana ndi zosowa zenizeni, kubweretsanso michere yomwe imafunikira ku mbewu, ndikuthetsa kusagwirizana pakati pa kufunikira kwa mbewu ndi nthaka.
Composite Feteleza Kupanga Line zimagwiritsa ntchito kupanga feteleza pawiri a njira zosiyanasiyana monga nayitrogeni potaziyamu, phosphorous potaziyamu perphosphate, potaziyamu kolorayidi, granular sulfate, sulfuric acid, ammonium nitrate ndi zina zosiyanasiyana.
Monga katswiri wopanga zida zopangira feteleza, timapereka makasitomala ndi zida zopangira komanso njira yabwino kwambiri pazosowa zosiyanasiyana zopanga monga matani 10,000 pachaka mpaka matani 200,000 pachaka.Zida zonse ndizophatikiza, zololera komanso zasayansi, zogwira ntchito mokhazikika, zopulumutsa mphamvu zamagetsi, mtengo wotsika wokonza komanso ntchito yabwino.Ndilo chisankho chabwino kwambiri kwa opanga feteleza wosakanikirana (wosakaniza wosakaniza).
Mzere wopangira feteleza wophatikiza ukhoza kupanga feteleza wapamwamba, wapakatikati komanso wochepera kuchokera ku mbewu zosiyanasiyana.Nthawi zambiri, feteleza wambiri amakhala ndi michere iwiri kapena itatu (nayitrogeni, phosphorous, potaziyamu).Lili ndi makhalidwe okhudzana ndi zakudya zowonjezera komanso zotsatira zochepa.Feteleza wophatikizana amathandiza kwambiri kuti umuna ukhale wokwanira.Iwo akhoza kusintha umuna Mwachangu, komanso kulimbikitsa khola ndi mkulu zokolola za mbewu.
Kugwiritsa ntchito mzere wopangira feteleza wambiri:
1. Njira yopanga sulfure-baged urea.
2. Njira zosiyanasiyana zopangira feteleza wa organic ndi organic pawiri.
3. Njira ya feteleza wa asidi.
4. Njira ya fetereza yaufa yama mafakitale.
5. Njira yayikulu yopangira urea.
6. Njira yopanga feteleza wa masanjidwewo a mbande.
Zopangira zopangira feteleza organic:
Zida zopangira feteleza zopangira feteleza ndi urea, ammonium chloride, ammonium sulfate, madzi ammonia, ammonium phosphate, diammonium phosphate, potaziyamu chloride, potaziyamu sulfate, kuphatikiza dongo ndi zodzaza zina.
1) feteleza wa nayitrogeni: ammonium chloride, ammonium sulfate, ammonium thio, urea, calcium nitrate, etc.
2) Potaziyamu feteleza: potaziyamu sulphate, udzu ndi phulusa, etc.
3) Phosphorus feteleza: calcium perphosphate, heavy calcium perphosphate, calcium magnesium ndi phosphorous fetereza, phosphate ore ufa, etc.
Mzere wopangira feteleza wophatikizika wa rotary drum granulation umagwiritsidwa ntchito makamaka popanga feteleza wophatikiza kwambiri.Round litayamba granulation angagwiritsidwe ntchito kupanga mkulu- ndi otsika ndende pawiri feteleza luso, pamodzi ndi pawiri feteleza anti-congested luso, mkulu nayitrogeni pawiri kupanga feteleza luso, etc.
Mzere wopangira feteleza wa fakitale yathu uli ndi izi:
Zopangira zimagwiritsidwa ntchito kwambiri: feteleza wapawiri amatha kupangidwa motsatira njira zosiyanasiyana komanso kuchuluka kwa feteleza wapawiri, komanso ndi oyenera kupanga feteleza wa organic ndi inorganic pawiri.
Mtengo wocheperako wozungulira komanso zokolola za biobacterium ndizokwera: njira yatsopanoyi imatha kukwaniritsa kuchuluka kozungulira kopitilira 90% mpaka 95%, ndipo ukadaulo wowumitsa mpweya wocheperako ungapangitse mabakiteriya ang'onoang'ono kuti apulumuke kuposa 90%.Chomalizidwacho chimakhala chokongola komanso kukula kwake, 90% yomwe ndi tinthu tating'onoting'ono ta 2 mpaka 4mm.
Njira yogwirira ntchito ndi yosinthika: njira yopangira feteleza pawiri ikhoza kusinthidwa molingana ndi zida zenizeni, chilinganizo ndi malo, kapena njira yosinthira makonda ikhoza kupangidwa malinga ndi zosowa zenizeni za makasitomala.
Kuchuluka kwa michere ya zinthu zomalizidwa kumakhala kokhazikika: kudzera mu kuyeza kwazinthu zosakaniza, kuyeza kolondola kwa zolimba zosiyanasiyana, zamadzimadzi ndi zida zina zopangira, pafupifupi kusunga bata ndi mphamvu ya michere iliyonse panthawi yonseyi.
The ndondomeko otaya gulu gulu kupanga fetereza mzere akhoza kugawidwa mu: zosakaniza zopangira, kusakaniza, kuphwanya tinatake tozungulira, granulation, kuwunika koyamba, tinthu kuyanika, tinthu kuzirala, kuwunika yachiwiri, anamaliza ❖ kuyanika tinthu, ndi kachulukidwe ma CD omalizidwa mankhwala.
1. Zopangira:
Malinga ndi kufunikira kwa msika komanso zotsatira zakutsimikiza kwa nthaka, urea, ammonium nitrate, ammonium chloride, ammonium thiophosphate, ammonium phosphate, diammonium phosphate, heavy calcium, potaziyamu chloride (potaziyamu sulfate) ndi zopangira zina zimagawidwa mosiyanasiyana.Zowonjezera, kufufuza zinthu, ndi zina zotero zimagwiritsidwa ntchito ngati zowonjezera mu gawo linalake kudzera mumiyeso ya lamba.Malinga ndi chiŵerengero cha formula, zosakaniza zonse zopangira zimatuluka mofanana kuchokera ku malamba kupita ku zosakaniza, njira yotchedwa premixes.Zimatsimikizira kulondola kwa kapangidwe kake ndikukwaniritsa zosakaniza zokhazikika.
2. Sakanizani:
Zopangira zokonzekera zimasakanizidwa bwino ndikugwedezeka mofanana, ndikuyika maziko a feteleza apamwamba komanso apamwamba kwambiri a granular.Chosakaniza chopingasa kapena chosakaniza cha disk chingagwiritsidwe ntchito posakaniza yunifolomu ndi kusonkhezera.
3. Gwirani:
Ziphuphu zomwe zili muzinthuzo zimaphwanyidwa pambuyo posakaniza mofanana, zomwe zimakhala zosavuta kuti zitheke kukonzanso granulation, makamaka pogwiritsa ntchito chophwanya unyolo.
4. Granulation:
Zinthuzo zitatha kusakanikirana bwino ndi kuphwanyidwa zimatumizidwa ku makina opangira granulation kudzera pa conveyor lamba, yomwe ndi gawo lalikulu la mzere wopanga feteleza.Kusankha granulator ndikofunikira kwambiri.Fakitale yathu imapanga disk granulator, ng'oma granulator, roller extruder kapena pawiri feteleza granulator.
5. Kuwunika:
The particles ndi sieved, ndi osayenera particles ndi kubwerera kumtunda kusanganikirana ndi oyambitsa kugwirizana kwa reprocessing.Kawirikawiri, makina a sieve amagwiritsidwa ntchito.
6. Kuyika:
Izi zimagwiritsa ntchito makina ojambulira odziwikiratu.Makinawa amapangidwa ndi makina oyeza okhawo, makina otumizira, makina osindikizira, ndi zina zambiri. Muthanso kukonza ma hopper malinga ndi zomwe makasitomala amafuna.Itha kuzindikira kuchuluka kwa zinthu zambiri monga feteleza wachilengedwe ndi feteleza wapawiri, ndipo imagwiritsidwa ntchito kwambiri m'mafakitale opangira chakudya komanso mizere yopanga mafakitale.
