この実施例では、スクリュープレス部分１２−１５は、プレス過程生材料が圧縮 されたとき、ゲート弁（仕切り弁）としても役立ぢ、密閉プラグを形成し、３５ で正圧また負圧から大気圧に送出される。材料から絞り出された水はゲートから 弁手段３６を通して大気圧に出される。In this embodiment, the screw press parts 12-15 are arranged so that the raw material is compressed during the pressing process. When closed, it also serves as a gate valve, forming a sealing plug, 35 It is sent from positive pressure or negative pressure to atmospheric pressure. The water squeezed out of the material is passed through the gate. It is vented to atmospheric pressure through valve means 36.
これらの実施例では、本発明を用いるとき、２，３の本質的な利点が得られる。These embodiments provide a few essential advantages when using the present invention.
かくして、材料の得られる乾燥度及び（又は）ユニットの生産性を増大でき、さ らに、組み込まれたスクリュープレスの機能が、さもないと必要な、余分なゲー トフィーダ（複雑で高価な装置である）に取って換わる。In this way, the obtainable dryness of the material and/or the productivity of the unit can be increased and Additionally, the built-in screw press functionality eliminates the extra games that would otherwise be required. It replaces tow feeders (which are complex and expensive equipment).
第３図に示す実施例で特に存在する問題は、材料通路２２がドラムを取り囲む部 分から離れて存在し、その結果、多量の材料が一時的に押し下げられて送りスク リュ一部分８−１０に入れられ、それによって次のスクリューブレス部分２９． ３０に一時的な過荷重を生じさせることである。A problem particularly present in the embodiment shown in FIG. 3 is that the material passage 22 surrounds the drum. as a result of which a large amount of material is temporarily pushed down on the feed screw. screw brace part 8-10, thereby inserting the next screw brace part 29. 30 to cause a temporary overload.
しかし、この問題は、送りスクリュー８−１０用の駆動手段１１に、送りスクリ ューの動作に必要な動力によって制御される可変回転速度を備えるように構成す ることによって、簡単な方法で解決される。However, this problem is caused by the fact that the drive means 11 for the feed screws 8-10 is Configured with variable rotational speed controlled by the power required to operate the This can be solved in a simple way by
通常よりも多量の材料が送りスクリューに落下するとき、必要な動力は増加量に 比例して増大する。同時に、新たな材料がドラムから送りスクリューに供給され る前に遅延時間が当然存在することになる。When a larger amount of material than usual falls onto the feed screw, the power required increases increase proportionately. At the same time, new material is fed from the drum to the feed screw. Naturally, there will be a delay time before this happens.
前述の内容に従って、誘導装置が以下のような機能を果たすことができる。即ち 、送りスクリューに必要な動力が増大するとき、送りスクリューを減速させ、必 要な動力が減少するとき、回転速度を通常の速度に戻すことである。それぞれの 機能に対する必要な遅延時間を動作条件の枠内で変更できる。According to the foregoing, the guidance device can perform the following functions. That is, , when the power required for the feed screw increases, the feed screw is decelerated and When the required power decreases, the rotation speed returns to normal speed. each The required delay time for a function can be changed within the framework of operating conditions.
このような誘導機能は、もちろん、送りスクリュー８−１０の回転速度をプレス 部分２９．３０の動力の対応する要求基準に従って制御するように実施できる。Such an induction function can, of course, press the rotational speed of the feed screws 8-10. It can be implemented to control the power of parts 29, 30 according to corresponding requirements.
