摘要： PURPOSE:To improve the efficiency by fixing blades cut in pieces in the peripheral direction to a rotary shaft, and partially convering the outer periphery of the blades with a covering member in an apparatus for excafating and collecting coal or the like. CONSTITUTION:When a rotary shaft 30 is rotated in the direction of an arrow C1, a flat blade 35a fixed to a fixing member 32a is also rotated in the same direction, whereby the outer peripheral portions of the end surfaces 37a, 35a cut into the cargo to be excavated. The excavated cargo is conveyed in the direction of an arrow D1 by the downstream surface 38a of the blade 35a in the direction of the arrow C1. The other similar blades 35b are also operated. In this arrangement, the transport efficiency can be increased to the maximum by suitably setting the angles formed with the blades 35a, 35b,... and the axis of a shaft 30. The outer peripheral portions of the blades 35a, 35b,... are coated with carbide tool. Thus, the efficiency can be improved.

摘要： PURPOSE:To detect azimuths in many directions by a simple single constitution, by detecting such a state that the substrate fixed to a detection rod presses a detection element by a spring force. CONSTITUTION:When the leading end part of the detection rod 2 provided to a detection 1 contacts with an obstacle, the detection rod 2 and the substrate 6 fixed to the base end part of said rod 2 generate angular displacement along a direction wherein the obstacle presses the leading end part of the detection rod 2. At this time, the substrate 6 is supported by a spring means (compression spring) 39 and energized to the side of the detection element 19 arranged on the side opposite to the detection rod 2 by a spring and, therefore, the substrate 6 displaced by spring force presses the detection element 19 in the angular displacement direction. The detection element 19 detects a pressing position and pressing quantity to detect the azimuth and contact degree of the obstacle contacted with the detection rod 2. This angular displacement operation is possible in an arbitrary direction and, therefore, the arbitrary azimuth based on the angular displacement operation f the detection rod 2 can be detected by the single detector 1.

摘要： PURPOSE:To improve the tapping capacity of a blast furnace by surely extracting and detecting only the oscillation arising from the fall of raw materials by a bell opening operation and exactly knowing the completion of raw material discharge. CONSTITUTION:A device for throwing charge into the blast furnace is constituted of a small bell 1 and large bell 2 for throwing the raw materials into the blast furnace and a movable armor 8 for bringing the raw materials falling from the large bell 2 into collision against each other to control the raw material distribution in the radial direction in the furnace. Oscillation detectors 111, 112 which respectively detect the oscillations generated during the discharge and collision of the raw materials in the bell 2 and the movable armor 8 among the same are provided. A furnace top sequence control device 12 which determines the completion of the raw material discharge from the time difference between the outputs of the respective oscillation detectors 111, 112 is provided.

摘要： PURPOSE:To throw charge in an intended distribution state into a blast furnace by determining the deviation between the actual opening speed and set opening speed of a bell positioned in the lowermost stage, calculating the correction opening speed therefrom and correcting the next set opening speed with said speed. CONSTITUTION:The opening time TSi and opening degree PSi of a large bell 2 for an optional number of batches are optionally set and are inputted to an input board 14 for setting and are stored into a furnace top sequence control device 12. The values (TSi, PSi) area successively drawn out in conformity with the batch progression of the furnace top sequence and are calculated and converted to the speed set value VSi of the large bell=PSi/TSi. On the other hand, the control device 12 determines the correction opening speed DELTAVi by the prescribed equation in conformity with the batch progression of the furnace top sequence and corrects the speed set value VSi of the large bell by using the same. The large bell 2 operate in accordance with the control set value (VSi+DELTAVi) and stops finally at the set open position PSi by receiving the limination by the collation and calculation with the pulse signal of a pulse transmitter 13.

摘要： PURPOSE:To obtain a coal-water slurry which can be prepd. by the on-line method at low cost with high accuracy, by stimulating the viscosity of a slurry contained in a wet mill based on the data detected with respect to the driving current or driving power of the wet mill and controlling the amt. of the water to be fed in accordance with the viscosity. CONSTITUTION:Coal is fed from a coal hopper 1 through a metering feeder 2 into a cylindrical wet mill 3. Separately, water is fed from a water tank 11 trough a feed pump 10 into the cylindrical wet mill 3. The cylindrical wet mill 3 is driven by means of a mill driving motor 6 through a mill driving gear 4 and a reducer 5. The coal is mixed with water within the mill 3. The mixture is pulverized and is discharged in the form of a slurry. The discharged slurry is filtered with a filter 12 to remove foreign matter and is stored in a tank 13. In the above process, the electrical input of a mill driving motor is detected with a current detector 7. The value of the electrical input is input into the feed water controller 9. The amt. of water to be fed with a feed pump 10 is controlled with an output controlling signal from the feed water controller 9, thereby obtaining a slurry having a constant viscosity.

摘要： PURPOSE:To improve operating efficiency of a belt conveyor system by controlling the belt conveyors constituting the system one by one through the tracking of loads. CONSTITUTION:With a belt conveyor A started, the start timing for a belt conveyor C is set according to the ''and'' condition between such a condition that a time t1 (the difference between the time t0 required for a load to travel on the belt conveyor A and an allowance time alpha0) has passed since the starting of the belt conveyor A and such a signal that the presence of the load on the belt conveyor A is detected by a current sensor. For stopping the belt conveyors in proper order from the upstream side, the unevenness in the braking torque and inertia of each of the belt conveyors is absorbed and the conveyors on the downstream side are stopped mechanically with slight time lags from the stopping of those on the upstream side.

摘要： PURPOSE:To reduce the cost of equipment and operating cost, by separating dust forming portions into a plurality of groups, and by collecting dust while alternating in order every group. CONSTITUTION:Covers 3 are provided with cover bodies 5 surrounding each upper portion and both sides of conveyors at the going-in side and the going-out side in the mutual connecting portions 4 of conveyors 1a, 1b, and dust in the bodies 5 is suction removed to a dust collector 9 through a wind pipe 6a for collecting dust and a dust collecting blower 8 revolution driven by means of a driving motor 7. The dust forming portions 2a-2c of the conveyors 1a, 1b are separated into three groups by setting one location to one group, and dampers 20 each opening and shutting operated by means of piston cylinder mechanisms 19 are mounted into wind pipes 6a-6c for collecting dust in order to collect dust by successively alternating the separated dust forming portions 2a-2c every group.
