Kaituhi: Smartweigh– Taumaha Upoko Maha

Ko te pauna maha-upoko (Te Ngaronga-i-te-Taumaha) he momo taputapu pauna tātari tauanga. Ko te kaupapa matua, ka whakamahia te pauna maha-upoko mō te tukanga pauna tonu hihiri, ka taea te kawe i ngā rauemi mata me whāngai tonu. Ko te pauna me te mahi tātari tauanga, ā, kei reira te rere katoa o ngā rauemi mata me te whakaatu i ngā mōhiohio rere katoa. Ko te tikanga, he pūnaha pauna raraunga pumau, e whakamahi ana i te hangarau pauna o te tauine peke raraunga pumau, ā, e whakamahi ana i te pūoko pauna hei pauna i te peke. Heoi, i roto i te papa whakahaere o te pauna maha-upoko, me tatau te taumaha kupenga i ngaro i ia wā o te tauine peke kia whiwhi ai i te rere katoa o ngā rauemi mata.

Ko te Pikitia 1 he tirohanga mahere o te kaupapa o te pauna maha-upoko. He whakaahuatanga poto o te pauna maha-upoko, te kaupapa hoahoa, te ine me te whakamahinga o ngā tawhā matua o te mahi me tōna take whakamahinga. Pikitia 1. Ko te mahere matua o te pauna maha-upoko. Ko te Pikitia 1 he hoahoa kauwhata o te hanganga o te pauna maha-upoko. Ko te tukunga, ina tae ki te taumata rauemi mōrahi, ka kati te takirere tukunga, ā, ka tautokona te pūwero pauna e te pauna maha-upoko. Kia tika ai te pauna, ka honoa ngā taha o runga me raro o te pūwero pauna kia rite ki te awa ngohengohe, ki te tomokanga me te putanga rānei, kia kore ai e whakamahia te taumaha kupenga o mua me muri, o ngā mīhini me ngā taputapu maui me te matau me ngā rauemi mata ki runga i te pūwero pauna.

Ko te taha matau o te Pikitia 1 he tirohanga mahere o te tukanga katoa o te whāngai tonu. He pūnaha huringa tō te tukanga katoa o te whāngai tonu (e toru ngā huringa e whakaaturia ana i te pikitia). E rua ngā huringa o ia pūnaha huringa: ina takoto kau te ipu pauna, ka whakatuwheratia te takirere tuku hei tuku i te rauemi, ā, ka piki haere tonu te taumaha kupenga o te rauemi mata i roto i te ipu pauna. Ina tae ki te taumata rauemi mōrahi i te t1, ka kati te takirere tuku. Ka tīmata noa te kawe tīwiri ki te riringi i te rauemi, kātahi ka tīmata te mahi a te pauna maha-upoko; i muri i tētahi wā, i te heke haere tonu o te taumaha kupenga o te rauemi mata i roto i te ipu pauna, ā, ka tae ki te taumata rauemi iti rawa i te t2, ka whakatuwheratia anō te takirere tuku, ā, ko te wā mai i te t1 ki te t2 ko te mahi Whakahau i te wā huringa whāngai; I muri i tētahi wā, ina piki haere tonu te taumaha kupenga o te rauemi mata i roto i te pūwero pauna, ā, ka eke anō ki te taumata mōrahi o te rauemi i te wā t3, ka kati te takirere tuku, ā, ko te wā mai i te t2 ki te t3 te wā huringa mō te tuku anō, me ērā atu. I te wā huringa o te whāngai kaha, ka aroturukitia te ōwehenga tere o te kawe tīwiri i runga i te tere rere inamata hei whakatutuki i tētahi whāngai pumau; i te wā huringa tango anō, ka mau tonu te ōwehenga tere o te kawe tīwiri i te ōwehenga tere i mua tata i te tīmatanga o te wā huringa. Hurihia te whāngai ki te tikanga aroturuki rere rōrahi pumau.

Nā te mea ka whakauruhia e te pauna maha-upoko te pauna hihiri me te pauna raraunga pumau, ā, ka whakauruhia hoki te whāngai kua whakakorea me te whāngai tonu, he ngāwari te hiri i te hanganga, ā, he pai mō te pauna i ngā rauemi mata tino pai pērā i te raima, te paura raima tere, te waro kua paura, te kai, te rongoā, me ētahi atu. Mā te whakahaere taumaha me te whakaranu, ka taea te whakatutuki i te tino tika me te rārangi pauna. 2. Te hiranga o te kaupapa hoahoa o ngā tawhā matua o te mahi a te pauna maha-upoko I te wā e hoahoa ana i te kaupapa o te pauna maha-upoko, me whai whakaaro ki ngā tawhā matua o te mahi pērā i te auau o te tukunga, te nui o te tukunga anō, te kaha o te hopa pauna, me te tere o te tukunga anō, ki te kore e kore e mahi tika te pauna maha-upoko i te mahi. I hokona e tetahi kaihoko he pauna maha-upoko mai i te kaihanga mō te tiaki taputapu i te papaanga mō te tātari āhuatanga. E toru noa iho ngā pūoko pauna 100kg i hokona. I muri i te whakamahinga, i kitea he kore pumau te pūwāhi kore, ā, i ētahi wā kāore te rere katoa e whakaatu i ngā mōhiohio me ētahi atu hapa noa.

I muri i te tono a te kaihanga i tētahi ki te wāhi mahi, ka kitea e rātou ko te waikawa boric te rauemi mata o te kiritaki, ko te kiato whanaunga ko 1510kg/m3, ko te rere katoa mōrahi ko 36kg/h anake, ā, ko te rere katoa noa ko 21~24kg/h. He iti rawa te rere katoa, ka whakamahia e te hopper e toru ngā pūwāhi tautoko pūoko pauna 100kg, ā, he nui rawa te kaha o te hopper tātari. Ka taea te whai i ngā ture wheako mahi tino taunakitia i raro nei "Ina nui te nui o te pungarehu, ka tīpakohia te auau tuku anō kia 15 ki te 20 ngā wā/h" Hei kawe, ko te taumaha kupenga o ia tuku anō he 36/15~36/20, arā, 1.9kg~2.4kg. Ko te taumaha kupenga o ngā rauemi mata e mau ana i ia pūoko pauna he iti iho i te 1 kg, ā, ko te whānuitanga ine tika he tata ki te 0.5~1%.

Ko te tikanga, ko te whānuitanga ine tika o te pūoko pauna me 10~30% neke atu rānei, kia tika ai te pauna. E ai ki te taumaha o te rauemi mata o te 2.4kg me te taumaha kupenga o te hopper me ngā taputapu whāngai (pērā i te kawe tīwiri), ko te taumaha katoa he tata ki te 10kg. Mena ka whakamahia ngā pūtau kawenga e toru, ka taea te whiriwhiri i te whānuitanga ine o ia pūtau kawenga mai i te 5kg~10kg. Arā, ka nui ake te whānuitanga ine o te pūoko 100kg i tonoa tuatahitia ki te 10-20 ngā wā, ka iti ake te pono o te pauna maha-upoko, ā, ka iti ake te tika o te pauna.

E whakaatu ana tēnei take me tutuki hoki te hoahoa o te pauna maha-upoko ki te paerewa hoahoa, ā, me whakatau ngā tawhā matua o ngā taputapu mīhini me te whakahaere o te pauna maha-upoko i muri i te tatau. 3. Te tatau i te hoahoa o ngā tawhā matua o te whakahaere o te pauna maha-upoko 3.1 Te tatau i te auau tukunga Kei te whakaahua 1 ngā taipitopito o te mahi a te pauna maha-upoko. Kei roto i ia pūnaha huringa te tukanga katoa o te tukunga, nō reira he aha te auau tukunga tika? Mō te pauna maha-upoko, ko te nui ake o te ōwehenga noho huringa o te whāngai kaha i roto i ia pūnaha huringa (te wā noho = te huringa o te whāngai kaha / te huringa tukunga anō), ko te pai ake, ko te tikanga me neke ake i te 10:1. Nā te mea he nui ake te tika o te wā huringa o te whāngai kaha i te wā huringa o te tango anō. Ko te nui ake o te noho huringa o te whāngai kaha, ko te teitei ake o te tika whānui o te pauna maha-upoko.

Ko te auau o te pūnaha tohanga toto mō ia wā kotahi o te pauna maha-upoko ka whakaatuhia whānuitia hei auau o te pūnaha tohanga toto mō ia hāora ina nui ake te nui o te pungarehu, arā, ngā wā/hāora. Nā te mea e hangai ana te whakaritenga ki te nui ake o te whāngai pungarehu mō ia hāora, ko te whāngai pungarehu mō ia wā kotahi (hei tauira, mō ia hēkona) he pūmau wā. Ko te iti ake o te auau o te pūnaha tohanga toto, ko te nui ake o te nui o te rauemi e tukuna ana i ia wā, ko te nui ake o te kaha me te taumaha kupenga o te hopara pauna, ā, ko te iti ake o te tika o te whakahekenga taumaha me te tatau mā te whakamahi i te pūoko pauna maha-whānui; ko te nui ake o te auau o te pūnaha tohanga toto, Ko te iti ake o te nui o ia tukunga toto, ko te iti ake o te kaha me te taumaha kupenga o te hopara pauna, ā, ko te teitei ake o te tika o te whakahekenga taumaha me te tatau mā te whakamahi i te pūoko pauna me te whānuitanga ine iti.

Heoi, he tino teitei rawa te auau o te pūnaha tohanga, he maha ngā wā ka tīmata, ka mutu hoki ngā taputapu mīhini whāngai, ā, he maha ngā wā ka huri te papa whakahaere o te pauna maha-upoko i waenga i te wā huringa o te whāngai kaha me te wā huringa o te whāngai anō, kāore i te tino pai. Ko ngā auau tukunga anō e tino taunakitia ana kei te Ripanga 1, engari ko te mea tino nui me te tino taunakitia ko ngā auau tukunga e toru kei waenganui. Hei tikanga o te wheako mahi, he tino pai te nuinga o ngā pūmanawa pūnaha whāngai taumaha-ngaro mō ngā rauemi paura me ngā rauemi kirikiri he iti te rere. ngā wā/haora.

Ina iti iho te nui o te whāngai pungarehu i te nui o te whāngai pungarehu, ka whakaitihia te auau o te whāngai anō, kia nui ake ai te tere noho o te whāngai kaha, he pai ake tēnei hei whakapai ake i te tika. Hei tikanga o te wheako mahi, ko ētahi tono he tino iti te tere rere katoa o te whāngai, ahakoa he iti rawa te kaha o te hopper, ka taea tonu te penapena rauemi mata mō te haora kotahi, neke atu rānei, ā, ko te wā mō te whāngai anō neke atu i te 1 haora. Ko te tauira e whai ake nei: Ko te rere katoa o te whāngai nui ake ko te 2kg/h. Ko te ōwehenga o te puranga rauemi mata ko te 803kg/m3. Ko te rere katoa o te whāngai nui ake ko te 2/803=0.0025m3/h. Mena he 0.01m3 te kaha o te peihana (tata ki te 25b250m×25b250m×Te rahi o te peihana poraka pēnei i te 25b250m), he rawaka te whakamahinga o ngā rauemi mata mō te 2h~3h, ā, kei raro iho i te 10kg te nui o ia whāngai, nō reira kāore he take mō te whāngai aunoa, ka taea te kī ko te whāngai ā-ringa he ture whakaputa me te hanga, engari he iti ake te rere katoa.

3.2 Kua tīpakohia e te tātai mō te tatau i te rōrahi o te tukunga anō te auau o te tukunga anō, kātahi ka taea te tatau i te rōrahi o te tukunga anō me te rōrahi katoa o te whāngai. E ai ki te tātari āhuatanga o te pauna maha-upoko: ko te tere rere katoa o te whāngai nui ake ko 275kg/h, ko te mātotoru papatipu o te rauemi mata ko 485kg/m3, ā, ko te tere rere katoa o te whāngai rōrahi nui ake ko 270/480=0.561m3/h. Ko te auau o te rauemi ka tīpakohia ko te 15 ngā wā/h. Ko te tikanga tatau mō te rōrahi o te tukunga anō koia tēnei: ​​ko te rōrahi o te tukunga anō = te nui o te pungarehu (kg/h)÷Kōmato (kg/m3)÷Auau tukunga anō (auau tukunga anō/h) I tēnei tauira, te rōrahi tukunga anō = 270÷480÷15=0.0375m33.3 Te tatau i te kaha o te peke taumaha Ko te kaha o te peke taumaha i roto i te kaupapa hoahoa ka nui ake i te rōrahi tukunga anō kua tatauhia. Nā te mea he mea tika kia whakaarohia kāore e taea te karo i te peke taumaha ina tīmata te tukunga anō. Kei reira anō ētahi "Rauemi mata toenga" ā, he wāhi rokiroki kei runga o te peke kāore pea e kī "wāhi wātea", ki te 20% ia, ka wehea te rōrahi tukunga anō ki te 0.6, ā, ka taea te whiwhi i te kaha o te peke e hiahiatia ana, ā, me kanapa te kaha o te peke taumaha whakamutunga e ai ki te kaha o te peke kua oti te whakatau. Tikanga tatau mō te rōrahi tuku anō: te taumaha i te kaha o te peihana = te rōrahi tuku anō ÷ Ko k: k te taupū kaha tatau o te peihana, ka taea te 0.4~0.7, ā, e tino taunakihia ana te 0.6.

I tēnei tauira, te Pūmanawa o te Hopu Pauna = 0.0375÷0.6=0.0625m3 Mena he whakatakotoranga te pūmanawa o te silo hanga pēnei i te 0.6m3, 0.2m3, 1.b2503, me ētahi atu, me kanapa tae atu ki te 0.08m3, ā, ko te pūmanawa o te hopu pauna me 0.08m3. 3.4 Ka tatauhia anō te tere tukunga nā te mea he pūmanawa maha-upoko te pauna. I roto i te huringa tukunga anō, ka tīpakohia te whāngai tikanga pūmau-pūmau iti-te tika, nō reira ka tohua kia tere ake te tere tukunga anō o te whāngai wiri (i te nuinga o te wā, me whakahaere i roto i te 5s~20s). Tikanga tatau mō te tere tukunga anō: tere tukunga anō = [rōrahi tukunga anō (m3)÷Te wā tukunga anō (s)×60(s/min)]+[Te rere katoa o te whāngai rōrahi nui ake (m3/h)÷60 (min/h)] I roto i te tātai 2, e rua ngā tūemi o te tere tukunga anō.
