Kev Taw Qhia rau Cov Khoom Siv Tsis Zoo / Pellet thiab Kev Txhim Kho (Buhler Fumsun CPM pellet zeb)

1. Cov khoom pellet yog khoov thiab nthuav tawm ntau qhov tawg ntawm ib sab
Qhov tshwm sim no feem ntau tshwm sim thaum cov khoom tawm ntawm lub nplhaib tuag. Thaum txiav txoj hauj lwm raug kho nyob deb ntawm qhov chaw ntawm lub nplhaib tuag thiab cov hniav yog blunt, cov khoom tawg los yog torn los ntawm cov cuab yeej txiav thaum nyem tawm ntawm lub qhov tuag, tsis yog raug txiav tawm. Lub sijhawm no, qee qhov khoom khoov ntawm ib sab thiab sab nraud nthuav tawm ntau qhov tawg.

Txoj kev txhim kho:
• Ua kom lub zog compression ntawm lub nplhaib tuag ntawm cov khoom noj, uas yog, nce qhov sib piv ntawm lub nplhaib tuag, yog li ua kom qhov ntom thiab hardness tus nqi ntawm cov khoom pellet;
• Txiav cov khoom noj kom zoo dua. Raws li ntev raws li molasses los yog rog ntxiv, qhov kev faib ua feem ntawm molasses lossis rog yuav tsum tau txhim kho thiab cov nyiaj ntxiv yuav tsum raug tswj kom ua kom cov khoom ntim ntawm cov khoom pellet thiab tiv thaiv kom tsis txhob pub khoom noj;
•Kho qhov kev ncua deb ntawm cov hniav txiav thiab qhov chaw ntawm lub nplhaib tuag los yog hloov nws nrog ib tug sharper txiav hniav;
•Txais cov nplaum hom granulation additives los txhim kho lub zog sib txuas ntawm cov khoom.

2. Kab rov tav tawg hla tag nrho cov khoom siv
Zoo ib yam li qhov tshwm sim hauv scenario 1, cov kab nrib pleb tshwm sim ntawm ntu ntu ntawm cov khoom, tab sis cov khoom tsis khoov. Qhov teeb meem no yuav tshwm sim thaum pelletizing fluffy pub uas muaj ntau ntawm fiber ntau. Vim tias muaj cov fibers ntev dua li qhov pore loj, thaum cov khoom siv extruded, qhov nthuav dav ntawm fibers ua rau cov kab nrib pleb hauv qhov hla ntawm cov khoom siv particle, uas ua rau cov tawv nqaij zoo li cov khoom noj.

Txoj kev txhim kho:
• Ua kom lub zog compression ntawm lub nplhaib tuag ntawm cov khoom noj, uas yog, nce qhov compression piv ntawm lub nplhaib tuag;
• Tswj lub fineness ntawm fiber ntau crushing, kom ntseeg tau tias qhov siab tshaj plaws ntev tsis pub tshaj ib feem peb ntawm cov particle loj;
• Ua kom ntau lawm kom txo tau qhov ceev ntawm pub dhau lub qhov tuag thiab nce compactness;
• Txuas lub sij hawm tempering los ntawm kev siv ntau txheej los yog lub thawv txias txias;
•Thaum cov hmoov av noo ntau dhau los yog muaj urea, nws tseem tuaj yeem tsim cov tawv ntoo zoo li pub zaub. Ntxiv noo noo thiab urea cov ntsiab lus yuav tsum tau tswj.

3. Cov kab nrib pleb tshwm sim hauv cov ntaub ntawv pellet
Cov mis pub mis muaj fluffy thiab me ntsis elastic procurement, uas yuav nqus dej thiab nthuav thaum kho los ntawm txias. Tom qab tau compressed thiab granulated los ntawm lub nplhaib tuag, nws yuav caij nplooj ntoos hlav sib nrug vim cov nyhuv ntawm dej thiab elasticity ntawm raw khoom nws tus kheej, uas ua rau cov kab nrib pleb.

Cov kev txhim kho yog:
• Hloov cov qauv, tab sis ua li ntawd yuav txo tau tus nqi ntawm cov khoom siv raw;
• Siv cov saturated qhuav qhuav;
•Txo cov peev txheej ntau lawm lossis ua kom qhov ntev ntawm lub qhov tuag kom ua tiav lub sijhawm khaws cia ntawm cov khoom noj hauv qhov tuag;
•Ntxiv cov nplaum kuj tuaj yeem pab txo qhov tshwm sim ntawm cov kab nrib pleb.
 
4. Radiative tawg ntawm cov ntaub ntawv pellet los ntawm ib qho chaw taw tes
Qhov zoo li no qhia tau hais tias cov khoom siv pellet muaj cov ntaub ntawv loj pellet, uas nyuaj rau kev nqus dej noo thiab cua sov hauv cov dej vapor thaum lub sij hawm quenching thiab tempering, thiab tsis yooj yim softened li lwm cov ntaub ntawv raw. Txawm li cas los xij, thaum lub sij hawm txias, qhov sib txawv softening theem ua rau qhov sib txawv ntawm qhov shrinkage, ua rau tsim cov radial tawg thiab nce pulverization tus nqi.
 
Cov kev txhim kho yog:
Tswj thiab txhim kho lub fineness thiab uniformity ntawm raw cov ntaub ntawv, kom tag nrho cov raw cov ntaub ntawv yuav tsum tau tag nrho thiab uniformly softened thaum tempering.

5. Qhov saum npoo ntawm cov khoom pellet tsis sib xws
Qhov tshwm sim saum toj no yog tias cov hmoov yog nplua nuj nyob rau hauv cov ntaub ntawv loj, uas tsis tuaj yeem ua kom muag muag thaum lub sij hawm tempering. Thaum dhau los ntawm qhov tuag ntawm lub granulator, nws tsis tuaj yeem ua ke zoo nrog lwm cov khoom siv raw, ua rau cov khoom tsis sib xws. Lwm qhov ua tau yog tias cov khoom siv hluav taws xob quenched thiab tempered yog tov nrog cov npuas npuas, uas tsim cov npuas npuas thaum lub sij hawm nias cov khoom noj rau hauv cov khoom. Nyob rau lub sijhawm thaum cov khoom raug nyem tawm ntawm lub nplhaib tuag, cov kev hloov hauv siab ua rau cov npuas tawg thiab ua rau qhov tsis sib xws ntawm cov khoom. Ib qho khoom noj uas muaj fiber ntau tuaj yeem ntsib qhov xwm txheej no.

Txoj kev txhim kho:
Tswj kom zoo ntawm cov hmoov pub, kom tag nrho cov ntaub ntawv raw tuaj yeem ua kom softened thaum txias; Rau cov ntaub ntawv raw nrog ntau npaum li cas ntawm fiber ntau, raws li lawv nquag ua npuas npuas, tsis txhob ntxiv ntau cov pa rau cov mis no.

6. Cov hwj txwv zoo li cov khoom siv pellet
Yog tias chav ntau dhau lawm, cov pa ntau dhau yuav muab khaws cia rau hauv fibers lossis hmoov. Thaum cov khoom raug extruded los ntawm lub nplhaib tuag, qhov kev hloov ceev ceev yuav ua rau cov khoom tawg thiab protrude los ntawm qhov chaw ntawm cov protein los yog cov khoom siv raw khoom, tsim prickly whiskers. Tshwj xeeb tshaj yog nyob rau hauv zus tau tej cov hmoov txhuv nplej siab thiab siab fiber cov ntsiab lus pub, ntau chav yog siv, qhov teeb meem loj dua.

Txoj kev txhim kho yog nyob rau hauv zoo tempering.
•Pub nrog cov hmoov txhuv nplej siab siab thiab cov ntsiab lus fiber ntau yuav tsum siv cov cua tsis tshua muaj siab (0.1-0.2Mpa) kom tso dej tawm thiab cua sov hauv chav rau kev nqus;
• Yog hais tias lub zog siab dhau lawm los yog cov kav xa dej hauv qab lub siab txo lub valve yog luv dhau los ntawm tus tswj hwm, uas feem ntau yuav tsum siab dua 4.5m, cov chav yuav tsis tso nws cov dej noo thiab cua sov zoo heev. Yog li ntawd, qee qhov chaw khaws cia rau hauv cov khoom noj khoom haus tom qab txias, uas tuaj yeem ua rau lub ntsej muag zoo li cov nyhuv particle hais saum toj no thaum lub sij hawm granulation. Nyob rau hauv luv luv, tshwj xeeb mloog yuav tsum tau them rau lub siab tswj ntawm lub chav thiab lub installation txoj hauj lwm ntawm lub siab txo valve yuav tsum raug.

7. Cov khoom ib leeg lossis cov khoom uas tsis sib xws ntawm cov tib neeg, feem ntau hu ua "cov ntaub ntawv paj".
Nws yog qhov tshwm sim hauv kev tsim cov khoom noj hauv dej, feem ntau yog cov xim ntawm tus kheej cov khoom extruded los ntawm lub nplhaib tuag ua tsaus lossis sib zog dua li lwm cov khoom ib txwm muaj, lossis cov xim saum npoo ntawm cov khoom tsis sib xws, yog li cuam tshuam rau cov tsos zoo ntawm tag nrho. batch ntawm pub.
• Cov khoom siv raw rau cov dej pub mis yog qhov sib xyaw ua ke, nrog ntau hom khoom siv raw, thiab qee cov khoom xyaw ntxiv rau me me, ua rau muaj kev sib xyaw tsis zoo;
• Cov dej noo tsis sib haum ntawm cov khoom siv raw siv rau granulation los yog sib tov tsis sib xws thaum ntxiv dej rau lub tov khoom;
• Cov khoom siv rov ua dua tshiab nrog granulation;
•Kev tsis sib haum xeeb ntawm cov phab ntsa sab hauv ntawm lub nplhaib tuag aperture;
• Kev hnav ntau dhau ntawm lub nplhaib tuag los yog lub siab rau cov menyuam, kev tso tawm tsis sib xws ntawm qhov me me.
