1.1中文摘要
目前,國內用于玉米粉碎的主要機型是臥式錘片粉碎機。該機型盡管優點較多,但其缺點也比較突出,這就是能量消耗大、生產率不高的問題。為解決這些問題,多年來,在設計上也采取了不少改進措施,如加大篩板包角、設計水滴形粉碎室、設計偏心粉碎室、加強輔助吸風等,這些措施雖也有一定效果,但受臥式錘片粉碎機整體結構的限制,難以有明顯的成效。另外,還有齒爪式粉碎機、立式粉碎機、水滴型粉碎機,齒爪式粉碎機其結構緊湊,體積小,可靠性高,但能耗大,對粉碎多種物料的適應性差;立式粉碎機生產率高,能耗低,無需吸風,換篩方便,有效地干擾或破壞了粉碎室內的氣物環流層,避免了重復無效的過度粉碎,但結構復雜,價格昂貴,顆粒大小的分級困難,不適合于普通的場合;水滴型粉碎機粉碎室呈水滴型,粉碎效率高,能耗小,但結構復雜,體積大,制造加工難,工藝復雜;揉搓式粉碎機采用動定齒盤,依靠動定齒盤之間的相對的高速運動,使被粉碎物受齒盤揉搓、沖擊,剪切,摩擦及物料彼此間沖擊等綜合作用,來粉碎物料。
關鍵詞:動定齒盤、篩片、揉搓、剪切、粉碎
1.2 Summary
Currently, the domestic used for the main model that the corn smash is the lie type hammer slice smash the machine. That model though the advantage is more, its weakness is also more outstanding, this is the energy to consume big, not high problem of rate of production.In order to resolve these problems, many in the last years, also adopted not a few improvement measure on the design, wrap the Cape and design the drop of water form to smash the room and design to lack of impartiality to smash the room and strengthen to lend support to absorb the breeze such as the enlargement plank etc., although these measures also have the certain result, is smash by the lie type hammer slice the machine is whole structural of restrict, and is hard to have obvious result.Moreover, still have the claw type to smash the machine, sign type to smash the machine, the drop of water type to smash the machine, the claw type smashes the machine its structure tightly packed, the physical volume is small, but can consume greatly, the credibility is high, to smash the adaptability of various material to differ;The sign type smashes the machine rate of production high, can consume low, did not need to absorb the breeze, change the convenience, availably interference or broke to第4頁
smash the indoor spirit thing circulation layer, avoid repetition invalid smash excessively, but the structure complications, the price is expensive, the ratings of the grain size is difficult, is not suitable for in common of situation;The drop of water type smashes the machine to smash the room to present the drop of water type, smashing the efficiency high, can consume small, but the structure is complicated, the physical volume is big, the manufacturing process difficult, craft complications;The roll type smashes the machine adoption to move certainly dish of , depend on move settle oppositebetween dish of of high speed sport, make to be smash the thing is pound at by the dish, shearing to slice, rub and material each other pound at etc. comprehensive function, smash the material.
