He aha ngā tikanga pelletizing mō ngā raina whakaputa granulation?

He maha nga mea rereke raina pelletizing ngā hoahoa kei te mākete, engari e rua ngā wāhanga matua o ngā raina whakapūpū katoa: ngā pūnaha whakapūpū matao me ngā pūnaha whakapūpū wera mata-mati. Ko te rerekētanga matua i waenga i ngā mea e rua ko te wā o te tukanga whakapūpū. He painga me he ngoikoretanga tō ia o ēnei pūnaha whakapūpū e rua!

Pūnaha tapahi matao

Kei roto i te pūnaha whakapūkara matao he matao, he rohe whakamatao (hau, wai rānei), he rohe whakamaroke (mēnā he wai te whakamatao) me te rūma whakapūkara. E rua ngā momo matua o ngā pūnaha whakapūkara matao, arā, ngā whakapūkara maramara me ngā whakapūkara rīpene.

a: Ka rere te pūmua rewa o te pūhui kirikiri mai i te taputapu whakaranu mā roto i te mate whitiki, i te mīhini huri rānei hei whakakoi hei kirikiri pūmua o te matotoru kua tohua. Ka whakapakeketia ngā kirikiri, ka whakamataohia i tawhiti i te wā e kawe ana, kātahi ka tapahia hei porowhita porowhita, tapawhā rānei me te mīhini whakakoi kirikiri i roto i te ipu para.

Ko te whakapūkara maramara he tikanga tawhito rawa atu mō te hanga pūkara mō te whānuitanga o ngā momo polymer mai i te nairon ki te pvc. Ngā Painga: He nui te putanga. E ai ki ngā pūrongo he tino pai te tika, me te kaha ki te hanga kirikiri tae atu ki te 1,843.69 kg/h. He tikanga hanga kirikiri matao tēnei, ā, he nui ake te tukunga haruru i te tikanga tapahi kirikiri mai i ngā pūmua rewa. He poto ake te roa o te ora o ngā pūmua tapahi totoka, ā, he raruraru te whakaputanga paura. Mō ētahi pūmua, ka kitea ētahi āhuatanga "mekameka witi".

b: Kua roa te whakamahinga o ngā mīhini whakapūkara ripi e whakamahia ana, tata rite tonu ki te roa o ngā mīhini whakapūkara ripi. Kei roto i tēnei ko te mate, he wāhanga whakamatao (kaukau wai, pupuhi rānei), he wāhanga whakamaroke (mēnā he whakamatao wai) me te maripi tapahi. Ka hangaia ngā ripi mā te tuku i te pūmua rewa mā roto i tētahi kōhao whakapae mā te whakamahi i tētahi mīhini, i tētahi papu taputapu rānei (ka mīhinihia ngā kōhao hou kia tika, ā, ka whakamahanahia kia ōrite te kounga o ngā ripi). Kia tukuna ngā ripi mai i te pokepokea ai, ka whakamataohia mā te pupuhi, mā te wāhi hau/korehau rānei, mā te kaukau wai rānei. Mēnā ka whakamahia te whakamatao wai, ka haere ngā ripi mā roto i tētahi wāhanga whakamaroke me te hauhautanga kaha hei tango i te makuku, kātahi ka tukuna ngā ripi ki te rūma whakapūkara ripi. Ka tapahia tika ngā ripi ki te roa e hiahiatia ana mā te whakamahi i te mahi kutikuti o tētahi takirua maripi pumau me te hurihuri. Ko te diameter o ngā ripi he 3.175 mm te whānui, ā, ko te roa he 3.175 mm, he mārama ngā kokonga.

c: Ko te tikanga tuku iho mō te tuhi rīpene ko te totoro i ngā rīpene mā roto i tētahi wāhanga whakamatao (he kaukau wai te tikanga), ā, i ētahi wā ka hinga, ka kore rānei e ōrite te rahi o ngā rīpene. He mea noa tēnei i roto i ngā pūmua he ngoikore te kaha rewa, pērā i te polypropylene, te polyester me te nairona. Ina hinga tētahi rīpene, ka paraia te rauemi, nō reira me tino aro ngā kaiwhakahaere. Mena ka kore e ōrite te tuhi o ngā rīpene, me tātari ngā pire i raro iho.

Ka taea te whakatutuki i ētahi atu momo hanga rīpene me te kore e tirotirohia e te kaiwhakahaere mā te whakamahi i tētahi kaikawe whāngai kōhao e peia ana e te motuka e tautoko ana, e wehewehe ana hoki i ngā rīpene mai i te mate ki te pelletizer. He ōrite ake te rahi o ngā rīpene e haria ana e tēnei momo kaha hurihuri, kāore e taka, nō reira he iti ake te tūponotanga ka parahia. Ko ētahi o ēnei tikanga ka taea te whakaputa i te 6803.89 kg/h, ki te whakaritea ki te 1814.37 kg/h mō te tikanga totoro, nā te mea he iti noa ngā rīpene ka taea e te kaiwhakahaere te tirotiro.

He iti te utu o ngā raina rīpene, he ngāwari ki te whakahaere, ā, he ngāwari hoki ki te horoi. He painga tēnei mō te whakaranu tae, nā te mea me horoi pai ngā taputapu ina whakawhitihia ngā puranga tae e rua. Heoi, ko te ngoikoretanga o te tikanga rīpene ko te wāhi e hiahiatia ana mō te wāhanga whakamatao, ko te roanga ka whakatauhia e ngā whakaritenga pāmahana o te polymer.

Pūnaha Tapahi Wera Mata Mate

E toru ngā momo matua o ngā pūnaha tapahi wera mata-mate, arā, ko ngā pūhui rehu, ko ngā pūhui wai-pū (mowhiti wai) me ngā pūhui raro i te wai. Ahakoa he rerekē ngā hoahoa o ēnei pūnaha, ko te pūnaha noa he kōhao mate, he rūma tapahi, he maripi porowhita hurihuri motuka, he reo whakamatao, me te tikanga whakamaroke i ngā pūhui (mēnā ka whakamahia te whakamatao wai).

He wāhanga nui te pokepokea kōhao o te pūnaha whakawera o te mata o te mate. Ka whakairihia poutū, whakapae rānei, ā, ka whakamahanahia mā te hinu, te mamaoa, te kātereti, te whakamahana whitiki rānei. Ko te wera hiko te tikanga mō ngā mate iti; heoi, ko ngā mate nunui ka whakamahanahia mā te mamaoa, te hinu rānei. He rerekē ngā rauemi hanga mate, engari ahakoa te rauemi, te reo whakamahana rānei e whakamahia ana, me ōrite te whānui o te kōhao o te mate; me nui te wera hei pupuri i te pāmahana o te pūmua puta noa i te tukanga; ā, me pakari, me maeneene hoki te mata o te mate hurihuri e hurihurihia ana e te maripi whakawera - e hiahiatia ana ēnei katoa hei hanga i te mate ōrite.

I te mea ka whakapūpūhia te pūmua rewa ki roto i te pokepokea ai, ka tapahia e te maripi whakapūpū, e hurihuri ana i te tere tino tiketike, kia rite ki ngā pūmua. I te nuinga o te wā, ka pā te maripi ki te mata o te pokepokea ai, ka tata rawa rānei ki te mata. Kia oti te tapahi i ngā pūmua, ka maka atu i te maripi mā te kaha porotītaha ka haria ki te reo whakamatao. Ka rerekē pea te rahi, te āhua, te rauemi me te whakamau o te maripi. I roto i ētahi pūnaha, ka utaina te maripi ki te puna hei whakarite aunoa i te tawhiti i waenga i te maripi me te mate; i roto i ētahi atu pūnaha, ka whakaritea ā-ringa te tawhiti i waenga i te maripi me te mate. I te mea ko te roa o te ora o te maripi e whakawhirinaki ana ki te tika o te whakaritenga maripi-ki-te-mate, te kaha o te pūmua, me te kaha o te kaiwhakahaere, he mea pai te tapahi i ngā pūmua pūmua i roto i te āhua rewa.

a: E taunakihia ana ngā pūwero rehu mō ngā pūwero e pāngia ana e te wera me te roa o te wā noho, pērā i te PVC, te TPR me te polyethylene hono-whiti. E hiahiatia ana ngā tere whakawero tae atu ki te 4989.52 kg/h kia poto ai te ara rere o te pūwero mai i te mīhini ki te rūma whakawero, kia iti ai hoki te wera e whakamahia ana. I te haerenga o te pūwero mā roto i te mate, ka tapahia e te kaha hurihuri o te mata o te mate hurihuri hei pūwero. Kia tapahia ngā pūwero, ka maka atu i te maripi hurihuri, ka hopukina e te hau e akiakihia ana kia rere i roto i te rūma whakawero motuhake. I te tīmatanga, ka tineia e te rere o te hau te mata o te pūwero, ka haria ki waho o te rūma tapatapahi ki roto i te rohe whakamatao.

He maha ngā whakamahinga o ngā whakamaroke moenga wai hei whakamatao i ngā pire. Ka nekehia ngā pire ki raro i tētahi arawhata ka taea te whakarite, ā, ka pupuhihia te hau e tētahi hau hurihuri mā roto i ngā pire. Mā te whakarite i te piko o te arawhata ka taea te whakaroa, te whakapoto rānei i te wā noho o ngā pire i roto i te whakamaroke. Ko tētahi atu tikanga whakamatao noa ko te tango i ngā pire mai i te rūma tapahi ki roto i tētahi tāke wai, ka tangohia te wai i roto i tētahi whakamaroke moenga wai, i tētahi whakamaroke pūwero rānei.
b: Ngā mīhini whakapūkara wai-pūngao, e tika ana mō te nuinga o ngā pūmua engari ko ērā he iti te matotoru rewa, he matotoru rānei. Ko te tere whakapūkara o ēnei mīhini, e mōhiotia ana ko ngā mīhini whakapūkara mowhiti wai, he 13,607.77 kg/h.

Ka tapahia te pūmua rewa hei kirikiri mai i te kōhao wera mā te maripi hurihuri e hurihuri ana ki te mata o te kirikiri. Ko te āhuatanga motuhake o tēnei pūnaha kirikiri ko te rūma kirikiri wai i hangaia mō te pupuhi wai. Ka rere te wai i roto i te porowhita tae noa ki te putanga mai i te rūma. Kia tapahia ngā kirikiri, ka makahia ki roto i te awa wai hei tinei tuatahi. Ka tukuna te paru wai kirikiri ki roto i te tāke paru kirikiri hei whakamatao anō, kātahi ka whāngaihia ki roto i te whakamaroke porowhita hei tango i te wai.

c: He rite te mīhini whakapūkara raro wai ki te mīhini whakapūkara rehu me te mīhini whakapūkara wai, engari he rere maeneene te wai e rere ana i runga i te mata o te mate, e pā tika ana ki te mata o te mate. He nui noa te rahi o te rūma whakapūkara kia taea ai e te maripi whakapūkara te huri noa i te mata o te mate me te kore e aukati i te rere o te wai. Ka haere te pūmua rewa i roto i te mate, ka tapahia e te maripi hurihuri ngā pire, ā, ka haria ngā pire i waho o te rūma whakapūkara e te wai kua whakamaroketia ki roto i te whakamaroke porowhita. I roto i te whakamaroke, ka tukuna te wai ki roto i te tāke rokiroki, ka whakamataohia, ka hangarua; ka haere ngā pire mā roto i te whakamaroke porowhita hei tango i te wai.

Me whakamahi te mīhini whakapūkara raro wai i te pokepoke waha me te tohatoha wera ōrite me ngā whakaurunga whakamahana wera motuhake. Ka whakamahanahia ngā maripi whakapūkara iti ki te hiko; me whakamahi ngā kōhao whakapūkara nui ki te hinu, ki te mamaoa rānei. Ka whakamahanahia te wai tukatuka ki ngā pāmahana teitei ake, engari kāore i te wera rawa hei pā kino ki te rere noa o ngā pire. Ka whakamahia ngā mīhini whakapūkara raro wai mō te nuinga o ngā pūmua, ā, ka taea e ētahi tauira te whakatutuki i te kaha whakapūkara o te 22,679.62 kglh. Ko te āhua o te rere o te wai i runga i te mata o te kōhao he painga nui ina whakamahia mō te whakapūkara i ngā pūmua matotoru iti, piri rānei, engari mō ētahi pūmua pērā i te nairona me ētahi waitohu polyester, ka taea e tēnei āhuatanga te whakatio i te kōhao. Ko ētahi atu painga ko: te iti o te tukunga haruru nā te mea ka mahia te whakapūkara i roto i te āhua rewa, ā, ka mahi te wai hei ārai haruru; me te iti ake o ngā huringa o ngā maripi whakapūkara ki te whakataurite ki ngā pūnaha tapahi makariri.
