Mushure mekunge mugadziri atuma mumwe munhu kunzvimbo iyi, vakaona kuti zvinhu zvakagadzirwa nemutengi iboric acid, huwandu hwehuwandu i1510kg/m3, huwandu hwepamusoro hwehuwandu hwehuwandu i36kg/h chete, uye huwandu hwehuwandu hwehuwandu hwehuwandu i21~24kg/h. Kuyerera kwehuwandu hudiki zvekuti hopper inoshandisa nzvimbo nhatu dzekutsigira sensor yehuremu hwe100kg, uye kugona kwehopper yekuongorora kwakakura. Munhu anogona kutevedzera mitemo yeruzivo rwebasa inokurudzirwa pazasi "Kana huwandu hwedota hwakura, huwandu hwekuburitsazve hunosarudza se15 kusvika 20 kanomwe paawa"Kuti zviendeswe mberi, huremu hwese hwekubvisazve humwe hunenge 36/15~36/20, kureva, 1.9kg~2.4kg. Huremu hwese hwezvinhu zvakagadzirwa zvinotakurwa ne sensor yega yega yehuremu hunenge huri pasi pe1 kg, uye chiyero chinonzwisisika chingangoita 0.5~1%.

Kazhinji, chiyero chinonzwisisika chesensor yekuyera chinofanira kunge chiri pakati pe10~30% kana kupfuura, kuitira kuti huremu hwacho huve hwakarurama. Zvichienderana nehuremu hwezvinhu zvekugadzira zve2.4kg pamwe nehuremu hwese hwehopper nemidziyo yekudyisa (senge screw conveyor), huremu hwese hunenge 10kg. Kana ma load cell matatu akashandiswa, chiyero chekuyera chesero rega rega rekutakura zvinhu chinogona kusarudzwa kubva pa5kg~ 10kg. Kureva kuti, chiyero chekuyera chesensor yekutanga ye100kg chinova chikuru ka10-20, zvichikonzera kusavimbika kwemuchina wekuyera wemitsetse yakawanda uye kusanyatsojeka kwehuremu.

Nyaya iyi inoratidza kuti dhizaini yemuchina wehuremu hwemisoro yakawanda inofanirawo kutevedzera mwero wedhizaini, uye maparamita makuru emidziyo yemuchina uye mashandiro emuchina wehuremu hwemisoro yakawanda anofanira kusarudzwa mushure mekuverenga. 3. Kuverenga dhizaini yedhizaini yezvikamu zvikuru zvekushanda kwemuchina wehuremu hwemisoro yakawanda 3.1 Kuverenga kwehuwandu hwekubuda kwemvura Mufananidzo 1 unotsanangura mashandiro emuchina wehuremu hwemisoro yakawanda. Sisitimu yega yega yekutenderera inosanganisira maitiro ese ekubuda kwemvura, saka chii chakakodzera kubudiswa kwemvura? Kune muchina wehuremu hwemisoro yakawanda, chiyero chekuvapo kwemuchina wehuremu hwemhepo chakakura muhurongwa hwega hwega hwekutenderera (nguva yekugara = kutenderera kwemuchina wehuremu hwesimba / kutenderera kwekuburitsazve), zviri nani, kazhinji inofanira kudarika 10:1. Izvi zvinodaro nekuti kunyatsojeka kwenguva yekutenderera kwemuchina wehuremu hwesimba kunopfuura nguva yekutenderera yekuburitsazve. Kugara kwemuchina wehuremu hwemhepo kwakakura, kunyatsojeka kwemuchina wehuremu hwemisoro yakawanda kwakakwira.

Kuwanda kwehurongwa hweropa panguva imwe neimwe yemuchina wekuyedza une misoro yakawanda kunowanzo tsanangurwa sehuwandu hwehurongwa hweropa paawa kana huwandu hwedota hwakakura, kureva kuti, nguva/awa. Nekuti chinodiwa chinobva pahuwandu hwakawanda hwekudya kwedota paawa, kudya kwedota panguva imwe neimwe (semuenzaniso, pasekondi) inguva inoenderana. Kuwanda kwekufamba kwehurongwa hweropa paawa imwe neimwe, huwandu hwakawanda hwezvinhu zvinoburitswa nguva imwe neimwe, huwandu hwakawanda hwehuremu hwehopper yekuyera, uye kuderera kwekururama kwekurasikirwa nehuremu nekuverenga uchishandisa sensor yekuyera ine nzvimbo diki yekuyera.

Zvisinei, kuwanda kwemafambiro emuchina wekutenderera kwakakwira zvakanyanya, michina yekudyisa inotanga uye inomira kakawanda, uye bhodhi rekudzora remuchina wehuremu hwemahedhi akawanda rinowanzo chinja pakati penguva yekutenderera kwemuchina wekudya wesimba nenguva yekutenderera yekudyisazve, izvo zvisina kunaka zvakanyanya. Mafambiro ekudzoreredza anokurudzirwa zvikuru anoratidzwa muTafura 1, asi anonyanya kukosha uye anokurudzirwa zvikuru ndiwo mafrequency matatu ari pakati. Semutemo wechiitiko chebasa, akawanda esoftware yekudzikisa uremu akakodzera zvinhu zvine hupfu uye zvinhu zvisina kunyorova zvakanaka. nguva/awa.

Kana huwandu hwemadota hwakaderera pane huwandu hwakawanda hwemadota, huwandu hwemadota anodyiswazve hunoderedzwa, zvekuti huwandu hwemadota anodyiswazve hunowedzera, izvo zvinobatsira zvikuru pakuvandudza kunyatsorongeka. Semutemo weruzivo rwebasa, mamwe mashandisirwo ane huwandu hwakaderera hwemadota anodyiswa, kunyangwe huwandu hwemahopper huri hudiki, anogona kuchengetedza zvinhu zvisina kugadzirwa kweawa imwe chete kana kupfuura, uye nguva yekudyazve inodarika awa imwe. Muenzaniso unotevera: Kuyerera kwese kwemuchina mukuru wekudya i2kg/h. Chiyero chemurwi wezvinhu zvisina kugadzirwa i803kg/m3. Kuyerera kwese kwemuchina mukuru wekudyara i2/803=0.0025m3/h. Kana kugona kwehopper kuri 0.01m3 (zvinenge zvakaenzana ne25b250m×25b250m×Saizi yecube hopper yakaita se25b250m), kushandiswa kwakakwana kwezvinhu zvisina kubikwa kwemaawa maviri kusvika matatu, uye huwandu hwese hwekudyisa huri pasi pe10kg, saka hapana chikonzero chekudyisa otomatiki, kudya nemaoko kunogona kutorwa semitemo yekugadzira nekugadzira, asi kuyerera kwayo kwakadzika zvishoma.

3.2 Fomura yekuverenga huwandu hwekuburitsazve yakasarudza frequency yekuburitsazve, uye ipapo vhoriyamu yekuburitsazve uye huwandu hwese hwechinodyisa zvinogona kuverengerwa. Zvichienderana nekuongorora kwakaitwa nemuchina wekuyeresa une misoro yakawanda: huwandu hwese hwekuyerera kwechinodyisa chikuru i275kg/h, huwandu hwakawanda hwezvinhu zvakagadziriswa i485kg/m3, uye huwandu hwese hwekuyerera kwechinodyisa chikuru i270/480=0.561m3/h. Kuwanda kwezvinhu kunosarudzwa ka15/h. Nzira yekuverenga huwandu hwekubudazve kwemvura ndeye: huwandu hwekubudazve kwemvura = huwandu hukuru hwedota (kg/h)÷Kuwanda (kg/m3)÷Kubudazve kwemvura (kubudazve kwemvura / h) Mumuenzaniso uyu, vhoriyamu yekubudazve kwemvura = 270÷480÷15=0.0375m33.3 Kuverengwa kwehuwandu hwehopper yekuyera Kugona kwehopper yekuyera muchirongwa chekugadzira pasina mubvunzo kuchapfuura huwandu hwakaverengerwa hwekubudazve kwemvura. Izvi zvinodaro nekuti zvakakosha kufunga kuti hopper yekuyera haidzivisiki kana yatanga kuburitsazve mvura. Kunewo "zvinhu zvakasara" uye pamusoro pehopper pane nzvimbo yekuchengetera isingakwanise kuva "nzvimbo yakasununguka" yakazara, kana imwe neimwe iine 20%, ipapo vhoriyamu yekubudazve kwemvura inokamurwa ne 0.6, uye huwandu hunodiwa hwehopper hunogona kuwanikwa, uye huwandu hwekupedzisira hwehopper yekuyera hunofanira kunge hwakapenya zvichienderana nehuwandu hwehopper yakapedzwa. Nzira yekuverenga yekuburitsa vhoriyamu zvakare: kuyera kugona kwehopper = vhoriyamu zvakare÷Apo k: k ndiyo indekisi yehuwandu hwakaverengerwa hwehopper, inogona kuva 0.4 ~ 0.7, uye 0.6 inokurudzirwa zvikuru.

Mumuenzaniso uyu, Weigh Hopper Capacity = 0.0375÷0.6=0.0625m3 Kana kugona kwechimiro chesilo kune zvakatsanangurwa zvakaita se0.6m3, 0.2m3, 1.b2503, nezvimwewo, chinofanira kupenya kusvika ku0.08m3, uye kugona kwehopper yekuyera kunofanira kuva 0.08m3. 3.4 Kuyerera kwemvura kunoverengerwa zvakare nekuda kwehuremu hwemahedhi akawanda. Munguva yekudzorazve simba, nzira yekudyisa ine simba rakaderera inosarudzwa, saka kumhanya kwekudyisa simba kwemudyisa unodyisa kunotsanangurwa kuti kunokurumidza (kazhinji, kunofanirwa kushanda mukati memasekonzi mashanu ~ 20). Nzira yekuverenga yekubudazve kwemvura: chiyero chekubudazve kwemvura = [huwandu hwekubudazve kwemvura (m3)÷Nguva yekubudazve kwemvura (s)×60(s/min)]+[Kuyerera kwese kwekudyara kwemvura yakakura (m3/h)÷60 (min/h)] Mufomura 2, chiyero chekubudazve kwemvura zvakare chine zvinhu zviviri.
