Abstract
【解決手段】 ろか静水圧発生手段(3)は、予脱水装置(2)に連結されたスラッジ入口(10)とスラッジ室(20)に連結されたスラッジ出口(17)とを有する複数のスポイト状のピストン・シリンダ・ユニット(14)として作用し、そこにはさらにスラッジ入口(10)とスラッジ出口(17)には交互に作動可能な閉鎖制御弁(12、21)が設けられ、圧板のうち上圧板(22)は固定され、そして予脱水装置(2)およびピストン・シリンダ・ユニット(14)は上圧板(22)の上に設置されることを特徴とするスラッジ及び類似物の脱水装置。
【選択図】図1
Description
この運動の間、複数のピストン・シリンダ・ユニット14はスラッジ室20の容積の1.5倍の量のスラッジを受容する。ユニット14の容積又は下記において更に詳しく説明する実施態様の対応手段の容積が、単に1ストロークでスラッジ室を最適な方法で充填する容積であることが特に重要である。ピストン・シリンダ・ユニット14を完全に充填した後、平滑り弁12は閉じられ、そしてその後、平滑り弁21、24が開かれる。その後、ピストン・シリンダ・ユニット14のピストンは駆動装置15によって前方位置に移動される。これは、ピストン・シリンダ・ユニット14の容積がスラッジ室20の容積より大きいために、スラッジ室20内に静水圧が発生することを意味する。その後、平滑り弁21、24は再度閉じられ、そして平滑り弁12は再度開かれることが好ましく、その後、ピストン14は駆動装置15によって後方位置に移動される。これは、ピストン・シリンダ・ユニット14は再度スラッジで充填されることを意味する。その後、平滑り弁12は再度閉じられ、そして平滑り弁21、24は再度開かれ、そしてピストン・シリンダ・ユニットのピストンは再度前方に移動され、スラッジ室20には約5バールの静水圧が発生する。スラッジ室内に静水圧が発生した後、平滑り弁21と24は再度閉じられ、そして平滑り弁12を再度開くことによってピストン・シリンダ・ユニットは完全に充填され、そして次のサイクルに供せられる。その後、高圧発生装置33を駆動することによって、下圧板23を上圧板22に対して上方に移動し、スラッジ室20の容積は減少する。これにより、例えば約30バールオーダの機械的な脱水圧が発生する。また、この圧力は以前の静水圧より極端に大きい。
