摘要： The invention concerns a lower sealing valve assembly for a shaft furnace charging installation. It comprises a lower sealing valve housing (1) with a lower outlet (7) through which charge material can freely drop onto a distribution device. The housing has at least one upper inlet (4, 6) for communicating with an outlet of a hopper arranged above the housing. Each inlet has an associated valve seat (12, 14) that is arranged inside the lower sealing valve housing and turned towards the interior of the housing (1). A shutter (40) is operatively connected to an actuation mechanism (46, 50) for moving the shutter into and out of sealing contact with the valve seat. The valve actuation mechanism comprises a turn-slide cylindric joint (50) having a typically vertical joint axis (51) for swiveling the shutter (40) in a plane perpendicular to the joint axis (51) inside the lower sealing valve housing and for translating the shutter (40) up and down along the joint axis (51). According to the invention, the cylindric joint comprises a shaft (52) that is axially fixed and rotatably in a hollow sleeve (54), which in turn is axially slideable in an outer shell (56) that is fixed to the housing. Further according to the invention, the mechanism comprises: a first hydraulic cylinder (72), which is connected on one side to the shell (56) and on the other side to the hollow sleeve (54) to impart axial translation to the sleeve and therewith to the shaft along the joint axis (51); and: a second hydraulic cylinder (74), which is hinged on one side to the sleeve and on the other side to the shaft, to impart rotation to the shaft (52) and about the joint axis (51).

摘要： The invention concerns a charging installation for a shaft furnace, in particular for a blast furnace, and especially the lower sealing valve assembly thereof. The installation comprises at least two hoppers (22, 24) acting as lock hoppers for intermediate storage of charge material to be charged into the furnace. The lower sealing valve includes a lower sealing valve housing (100) arranged below the hoppers. The lower sealing valve housing (100) has at least two inlets (104, 106) respectively communicating with one of the hoppers and an outlet (107) for passing charge material into the furnace. Each inlet has a respective associated valve seat (112, 114) providing gas-tight sealing of the hoppers downstream. The lower sealing valve assembly further includes a sealing valve mechanism (140, 146, 150) for sealing the inlets, more specifically for closing the seats in technically gas-tight manner. According to the invention, the sealing valve mechanism (140, 146, 150) comprises a one-sided shutter (140) having a single sealing face (142) that cooperates with both of the at least two valve seats (112, 114), by virtue of the sealing valve mechanism being configured to bring the sealing face (142) of the one-sided shutter (140) into sealing contact in turn with each of the at least two valve seats (112, 114) for sealing the associated inlet (104, 106).

摘要： The invention relates to a device for immobilising the chute on the ends of journals in an apparatus for loading a shaft furnace, comprising a pivotable chute (1) for distributing material, the chute being connected to support journals (2) by means of tabs (11) which are inserted into recesses (21) arranged on the journals and which are immobilised thereon by means of pins (3) comprising an eccentric nipple (31) at the end thereof which is inserted in a lug of the chute in order to keep the lug immobilised at the bottom of the recess thereof, and locking means (4) for rotationally locking the chute. Each chute comprises, at the outer end thereof opposite the nipple, means (32) for rotational adjustment and for clamping in order to be able to press the nipple onto the lug of the chute using sufficient force by means of rotating the pin, and the locking means comprising an indexing plate (41) which is rotatably connected to the end of the pin (3), the plate (41) further comprising teeth (416) which are arranged so as to engage in the corresponding teeth (421) of a lock (42) which is rigidly connected to the journal in such a way that said lock can render the pin unable to rotate in a plurality of circumferential positions of said pin.
