用于地质钻探设施的振动筛选机
摘要：
本发明涉及一种石油和天然气钻探设施(10)，该设施具有：钻架(11)，该钻架具有在预定高度设置有出口的钟形接口管(14)；具有进料器(23；101)和角度可调节振动架(25；111)的筛选机(15；140)；位于所述进料器(23；101)和所述振动架(25；111)之间的溢流堰(24；100)，该溢流堰(24；100)具有低于钟形接口管的出口的预定高度并且就在筛架邻近溢流堰(24；100)的部分之上的高度，以及钟形接口管(14)和进料器(23；101)之间的向下倾斜的导管(22)。本发明还涉及一种振动筛选机(15；140)和进料器(23；101)联合装置，其包括位于振动筛选机(15；140)上的角度可调节的振动架(25；111)、在进料器(23；101)与振动架(25；111)之间并且就在筛架(25；111)邻近溢流堰(24；100)的部分之上的高度处的溢流堰和挠性密封件(24；100)。
摘要（英）：

An oil and gas drilling installation having a drill rig with a bell nipple having an outlet at a predetermined elevation, a screening machine having a feeder and an angularly adjustable vibratory frame, a weir positioned between the feeder and the vibratory frame, the weir having an elevation which is lower than the predetermined elevation of the outlet of the bell nipple but immediately above the portion of the screen frame adjacent to the weir, and a downwardly inclined conduit between the bell nipple conduit and the feeder. A vibratory screening machine and feeder combination including an angularly adjustable vibratory frame on the vibratory screening machine, and a weir and flexible seal between the feeder and the vibratory frame at an elevation which is immediately above the portion of the vibratory frame which is adjacent to the weir.
