1.1 Chidule cha fakitale yokonzekera malasha
Malo Okonzera Malasha a Longquan a Taiyuan Coal Gasification Company ndi makina akuluakulu okhala ndi mphamvu ziwiri okhala ndi kapangidwe ka 5.00Mt/a omwe amapanga malasha ophikira ndipo amaganizira kwambiri za kupanga malasha otentha. Dongosolo la matope oundana a malo okonzera malasha ndi 5% ya kuchuluka kwa malasha osaphika ndipo ali ndi mphamvu yokonza ola limodzi ya 56.82t/h.
1.2 Njira yosankhira
Njira yokonzekera malasha pakupanga fakitale yokonzekera malasha ndi iyi: Makala aiwisi atachotsedwa ndi kufufuzidwa (chophimba chochotsera 1mm), 50 ～1mm chimalekanitsidwa ndi chimphepo champhamvu cha zinthu zitatu chochotsa 1mm cholemera, 1 ～0.25mm. Madzi a malasha okhuthala amalekanitsidwa ndi TBS, ndipo madzi a malasha okhuthala a -0.25mm amabwezedwanso mwa kukhuthala ndikufinya ngati chinthu cha malasha chapakati.
2.1 Kulekanitsa ndi kubwezeretsa njira yochotsera utsi wochuluka musanayambe kusintha kwaukadaulo
Njira yolekanitsira ndi kubwezeretsa utsi wochuluka isanayambe kusintha kwaukadaulo kwa Longquan Coal Preparation Plant ndi iyi: kuchuluka kwa mphepo yamkuntho + kulekanitsa TBS + kuchuluka kwa mphepo yamkuntho + arc seeve desliming ndi dedication + centrifuge dedication. Njira yeniyeniyo ikuwonetsedwa pa Chithunzi 1.
Chithunzi 1 Tchati cha kayendetsedwe ka ndondomeko ya kulekanitsa kwa matope osalala asanayambe kusintha kwa ukadaulo
2.2 Pali vuto
Gome 1 likuwonetsa deta yoyesera kutsekereza ya zomwe sefa yokhotakhota imagwiritsa ntchito komanso zinthu zomwe zili pa sikirini pomwe sefa yokhotakhota idagwiritsidwa ntchito kudula ndikugawa kuchuluka kwa TBS concentrate isanachitike kusintha kwaukadaulo. Kuchokera ku kufananiza deta yoyesera kutsekereza, zitha kuwoneka kuti kusiyana pakati pa kuchuluka kwa phulusa la zinthu zomwe zikubwera ndi sefa ndi kochepera 5%, zomwe zikusonyeza kuti kutsekereza bwino kwa sefa ya arc ndikochepa ndipo zotsatira zake zochepetsa phulusa ndizochepa kwambiri.

Malo Okonzera Malasha a Longquan ali ndi phulusa lochuluka, matope akuluakulu a gangue, phulusa lamkati lambiri, zokolola zochepa, komanso zinthu zambiri zapakatikati. Chifukwa chake, popanga zinthu zenizeni, kapangidwe koyambirira ka njira yolekanitsira ndi kubwezeretsa matope a coarse slime kumakhala ndi mavuto awa:
Njira yoyambirira imagwiritsa ntchito chophimba chooneka ngati arc chomwe chimagwira ntchito yochepetsera kutsekeka kwa TBS concentrate. Chifukwa cha matope akuluakulu a gangue m'malasha osaphika komanso kuchuluka kwa matope abwino a phulusa, izi zingayambitse: chophimba chopindika chimakhala ndi matope ambiri a phulusa, zomwe zimapangitsa kuti malasha opindika komanso oyera azikhala ndi phulusa lochuluka; chophimba chopindika chimagwiritsa ntchito chitsulo chosapanga dzimbiri. Chophimba chopindika chili ndi mpata waukulu wa chophimba ndipo n'chosavuta kuvala, zomwe zimapangitsa kuti phulusa lochepa la phulusa litayike ndikutaya malasha oyera. Nthawi yomweyo, chophimbacho chiyenera kusinthidwa pafupipafupi.
3.1 Ndondomeko yosinthira ukadaulo
Pofuna kupititsa patsogolo kuchuluka kwa kubwezeredwa kwa malasha oyera komanso phindu lazachuma, Longquan Coal Preparation Plant pamodzi ndi Anhui Fangyuan Plastic Co., Ltd. kuti asinthe njira yolekanitsira utsi wochuluka. Pambuyo pa chiwonetserochi, idagwiritsa ntchito mwachindunji Anhui Fangyuan Plastic Co., Ltd. kuti ipange mawonekedwe abwino kwambiri, chophimba cha FY-HVS-1500 chokhala ndi mawonekedwe apamwamba chokhala ndi zotsatira zabwino zochotsa utsi chimalowa m'malo mwa chophimba chopindika kuti chidule bwino komanso moyenera zinthu zomwe TBS imadzaza ndikuchiphimba.
3.2 Kapangidwe ndi mfundo yogwirira ntchito ya FY-HVS-1500 laminated high frequency screen.
Chinsalu chotchingira cha Fangyuan FY-HVS-1500 chokhala ndi ma frequency stacked ndi mtundu wa zida zamakanika zomwe zimagwiritsa ntchito kugwedezeka kwa ma frequency pamwamba pa chinsalu ndi mphamvu yokoka ya zinthuzo kuti zigwirizane ndi kukula kwa tinthu ta zinthuzo. Kapangidwe kake kamakhala ndi chogawa, chodyetsera, ndi mafelemu a chinsalu chapamwamba ndi chapansi. , Mota yotchingira ma frequency ambiri, chosungira zinthu pazenera, thanki yosungira zinthu pansi pa chinsalu, chimango ndi nsanja yothandizira. Mfundo yogwirira ntchito ya makina osinkhira ikuwonetsedwa pa Chithunzi 2. Makhalidwe ake akuluakulu ndi zabwino zake ndi izi:

Malo Okonzera Malasha a Longquan adakonza njira yolekanitsira ndi kugawa ma slame coarse slime, ndipo adagwiritsa ntchito ma screen apamwamba komanso ogwira mtima opangidwa ndi laminated high-frequency m'malo mwa ma arc screen kuti asindikize ndikugawa ma coarse slame slime, kuchepetsa kuchuluka kwa ma coarse slame. Phulusa lochuluka ndi matope abwino zimapangitsa kuti phulusa la mankhwala otsiriza a malasha oyera likhale lotsika kuposa phulusa lomwe limafunikira ndi malasha oyera onse. Nthawi yomweyo, vuto la kuthamanga mopanda mphamvu pansi pa sieve limathetsedwa bwino. Mayeso a fakitale yokonzekera malasha adawonetsa kuti phulusa la slage ya malasha pansi pa sieve linawonjezeka kuchoka pa 55% kufika pa 65%, ndipo zokolola za sieve zinawonjezeka ndi pafupifupi 5% poyerekeza ndi sieve ya arc, ndipo phindu lachuma la fakitale yokonzekera malasha linakula kwambiri.
