20.500.12556/DKUM-16761 ODPRAVA MAŠENJA V CIKLONU MEŠALCA MOČNIH KRMIL Elimination of stopping in cyclone mixer of strong feedings V diplomskem delu je raziskan problem mašenja ciklona mlina za mletje zrnja proizvajalca opreme za močno krmo 'Strojno ključavničarstvo Emilijan Rudolf', ki je namenjen mešanju močne krme na kmetiji. Ugotovljeno je bilo vsakokratno mašenje ciklona nad mešalcem, ko se je mešalec napolnil z mletim zrnjem do višine ciklona. Zaradi te napake je moral delavec opazovati dogajanje v mešalcu in ročno vključiti mešalo, da se je zmleto zrnje enakomerno porazdelilo po mešalcu. Z dograditvijo kapacitivnega senzorja na ciklon pri vhodu v mešalec se je napaka odpravila, povečali sta se produktivnost in zanesljivost mešanja. Nameščeni kapacitivni senzor tako zazna višino mlete mase in sproži mešalo, ki enakomerno razporedi maso po mešalcu, kadar nivo zmletega zrnja doseže kritično točko. Porabljeni čas za opazovanje mešalca lahko sedaj delavec porabi za nasipavanje zrnja v zaboj za mletje zrnja. Preizkus učinkovitosti naprave je bila narejen z mletjem različnih vrst žit (koruza, pšenica, ječmen) in soje. Merili smo čas od pričetka mletja zrnja do prve zamašitve, oziroma, ko je senzor zaznal zamašitev, in čas do maksimalne kapacitete mešalca. Pri merjenju smo ugotovili, da se najhitreje zamaši mleta koruza (18 min in 54 s), najkasneje pa soja (26 min in 34 s). In a diploma work a problem of stopping of cyclone for mill grinding of grains of strong fodder on farm produced by »Strojno ključavničarstvo Emilijan Rudolf« was researched. Frequently stopping of cyclone in the mixer was found, when the mixer was filled to the level of cyclone. Subsequently a worker had to watch on the mixer in case of stopping and engage the mixed by hand so that ground grains were distributed evenly round the mixer. A fault was remedied with adding of capacity sensor on cyclone at entrance in the mixer, which increased productivity and reliability of mixing. The installed capacity sensor sets off paddle, which sorts mass according to mixer evenly, when the level of ground grains achieves critical point. A farmer can now use his time for loading up of grains to trunk for grinding of grains instead of watching the mixer. A test of efficiency of device was made with grinding of different kinds of grains (maize, wheat, barley and soybean). A time from beginning of grinding of grains to first blockage as well as the time to maximum capacity of mixer was measured. It was found at that the maize sealed the first (18 min and 54 sec) and soybean the last (26 min and 34 sec). mešalec močnih krmil kapacitivni senzor mlin za mletje zrnja mixer of strong feedings stuffs capacity sensor mill for grinding of grains true true false Slovenski jezik Angleški jezik Diplomsko delo 2010-11-17 20:23:02 2010-11-30 14:38:49 2022-04-11 03:38:29 2023-12-21 03:16:09 2010 0 Maribor 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 URN:SI:UM:DK:NHDJMQ2B Fakulteta za kmetijstvo in biosistemske vede 0 0 0
