摘要： PURPOSE:To eliminate influence of weather and control dust pollution, by transporting water-crushed slag, after heating and drying in a hopper, to a pier and loading a ship by means of a pneumatic conveyor using compressed air. CONSTITUTION:Water-crushed slag 2 produced in an iron-works is transported by a truck 1 and put in a hopper 3 through a charging device 4 and dehydrated under heat treatment using steam piping 7 arranged in the hopper 3. Air with high water content is discharged from a ventilating port 5 equipped with a filter 6 for arresting dust. The dehydrated slag 2 is discharged through a gate 10 and dumped on a tank wagon 11 for transporting to a pier. The slag 2 is then pneumatically conveyed into a hold aboard a ship through a valve 13 by means of compressed air fed from a valve 12.

摘要： PURPOSE: To provide a method of easily and quickly grasping the shape of a hold required for the automatic operation of a continuous unloader at initial manual operation. CONSTITUTION: When the load of goods is carried by the manual operation of a continuous unloader, the tip position of a dig-out part 11 from a base point on a quay is computed from the position of a travel frame 2, the swivel angle and the elevation angle of a boom 4, the swivel angle of a bucket elevator 5, the expansion quantity of a dig-out part 11 and the like and the tip position of the dig-out part 11 is corrected from the relative position of a ship S with respect to the continuous unloader. The closest position of the tip position of the dig-out part 11 to the wall of a hold 20 within a divided zone at the time of diging operation of one layer is adopted as the maximum reach position to seek a plane shape in the hold by connecting the maximum reach position in the lateral direction at the time of diging operation of every layer. It is repeated at every time of cutting-in and the maximum reach position of a vertically continuous zone is connected in the direction of a depth to seek a profile shape inside the hold. The three-dimensional shape inside the hold is computed from both shapes.

摘要： PURPOSE:To improve the kneading performance and kneading treatment capacity of a kneading machine by specifying the ratio of the cylindrical inside diameter of an exciting and kneading machine to the diameter of a compacting medium, the filling rate of the compacting medium and the speed of rotations in an exciting motor. CONSTITUTION:The ratio of the cylindrical inside diameter of an exciting and kneading machine to the diameter of a compacting medium is regulated to >=15, and the filling rate of the compacting medium in the exciting and kneading machining is regulated to 13 to 50%. Then, a pulverized sintering raw material is fed to the above exciting and kneading machine and is kneaded. At this time, for executing the kneading under the operating condition of 3 to 10g vibrating acceleration in the kneading machine, the speed of rotations in an exciting motor of the exciting machine, e.g. in a vibro motor is controlled. At the time of kneading the pulverized sintering raw material under the above-mentioned conditions, the moisture content in the kneaded material is made uniform, and its pelletizing properties in the following pelletizing stage is remarkably improved. Moreover, by the compacting effect, the ball strength of the kneaded material is improved, and furthermore, the effects of accelerating the circulating speed of a rod and the transferring speed of the raw material, improvement in treating capacity or the like can be obtd.

摘要： PROBLEM TO BE SOLVED: To automatically move a drilling part between hatches, and to automatically insert the drilling part into the hatcheds by controlling the drive of a traveling frame, a turning boom and a bucket elevator based on the movement command to move the drilling part between the hatches of a ship. SOLUTION: Because a hatch H1 at which a drilling part 25 is first carried out is preset, a column member 22 of a bucket elevator 20 is located at a hatch opening of the hatch H1, the target position where the drilling part 25 is parallel to a sea-side opening part of the hatch opening is preset based on the ship type data and the relative position data, and the movement route to move the drilling part 25 from the present position to the target position in the shortest distance without bringing the drilling part into contact with a hull is calculated. The movement commands to a traveling control device 51, a turning tower control device 52, a turning boom control device 53, an elevator turning control device 54, and a tilt link part control device 56 are generated based thereon, and transmitted to the respective control devices. The drilling part 25 is thus started to move to the designated hatch H1.

摘要： PROBLEM TO BE SOLVED: To control excavated depth into an optimum one when using a continuos unloader which unloads cargo from a hold. SOLUTION: This unloader has a revolving boom which is mounted, in such a way as to be able to revolve up and down, on a revolving tower provided on a traveling frame in such a way as to freely revolve, and a revolvable bucket elevator is hung from the end of the revolving boom, and an excavating part whereby a bucket is turned is mounted at the lower end of the bucket elevator via a tilting link part. In this case, leading ultrasonic distance sensors 44a-44c and following ultrasonic distance sensors 45a-45a are placed, respectively, at positions leading and following the excavating part 25, and are used to detect the surface configuration of a subject to be excavated, and the depth excavated by the excavating part 25 is controlled according to the values detected by the sensors to perform a fixed amount of excavation.
