Filed: 1954-06-09
Abstract: 747,542. Charging blast furnaces. INTERLAKE IRON CORPORATION. June 9, 1954 [Aug. 4, 1953], No. 16937/54. Class 51(2) In blast furnace charging apparatus of the double-bell type in which a rotary hopper associated with the small bell is fed by a pair of skips, the charge materials are caused to enter the rotary hopper from each skip in a direction which is generally opposite to the direction of the hopper. Charge material fed into a receiving hopper 30 from the skips 31 running on tracks 32 drops into the rotary small bell hopper 20 with a rotary movement which will normally be opposite the direction of rotation of the hopper with one skip and in the same direction with the other skip. Reversing apparatus Fig. 6 is provided in order to overcome this effect by a reversal of the direction of rotation of the hopper 20 at the end of each skip dumping movement. This apparatus comprises a current supply source 36, a main switch 61, a reversing switch 62, a motor 63 operating the skip hoist, a timer 64, a hopper control switch 65 and a hopper driving motor 66. Closing switch 62 energises the timer, which closes theswitch 65 starting the hopper motor shortly before the skip reaches its discharge point. Movement of the switch 62 to the dotted line position 62A reverses the field of the motors 63 and of the motor 66, again energises the timer to close the switch 65 starting up the hopper motor 66 in a reverse direction. In a modification Fig. 4 in which the small bell hopper is rotated continuously in one direction, the receiving hopper 30 is divided unequally by a partition 80 and the bottom and side walls between the partition 80 and the end wall 81 are sloped downwardly and inwardly to terminate in air opening 85 which is a sector of the circular opening 35.
