Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention, when the bulk, granular, or powdered bulk material is charged into the container as the charging target, such as charging the material to be stored in the hopper or charging the raw material to the melting furnace, The present invention relates to a drum type disperser for widely and uniformly dispersing and charging.

[0002]

[Prior art]

 For example, as shown in FIGS. 6 and 7, when the throwing target B is thrown into the hopper 2 from the belt conveyor 1, the dropping target B has a limited drop position and is unevenly accumulated in the hopper 2. The volume efficiency of the hopper 2 is poor. Therefore, as shown in FIGS. 8 and 9, the drum type disperser 3 is used to throw the object B into the center of the hopper 2.

[0003]

[Problems to be solved by the device]

 However, in the conventional drum type disperser 3, since the drum having a smooth surface is rotated at a constant speed, if the object B to be charged has the same characteristics, the front-rear direction is approximately in the central part in a certain range. Further, the drum is loaded in the width direction of the drum in the left-right direction, and is piled up in a pile with the dropping position at the center as the apex. Therefore, when throwing the throwing target B into the hopper 2, the deviation in the position of the apex of the deposit is corrected, but the volumetric efficiency is not improved to the left. In addition, when a raw material is charged into a melting furnace or the like as an object to be charged, it is difficult to adjust the air volume at the tuyere because the material is not deposited flat.

The present invention solves such a problem in throwing an object to be thrown into a container such as a hopper, which can be thrown in a wide range in the front-rear direction and the left-right direction, and can improve volumetric efficiency. An object of the present invention is to provide a drum type dispersing machine that can be used.

[0005]

[Means for Solving the Problems]

 SUMMARY OF THE INVENTION In order to solve the above problems, the present invention provides a drum type disperser for throwing loose material supplied from a conveyor into a container, a drum provided with diffusion blades for diffusing and discharging the loose material in the left and right directions, and the rotation of this drum. And a variable speed control means for changing the speed. By using an inverter unit and a sequencer for controlling the rotation speed of the motor for driving the drum as the variable speed control means, the rotation speed of the drum can be easily controlled according to the conditions.

[0006]

[Action]

 When the rotation speed of the drum is low, the input object is discharged near the drum, and when the rotation speed is high, it is discharged farther forward from the drum. Therefore, if the rotation speed of the drum is periodically changed within a predetermined range by the variable speed control means, the object to be charged is charged so as to be widely and uniformly dispersed in the front-rear direction. Further, the object to be charged is discharged by the diffusion blade so as to be diffused in the left-right direction of the drum. Therefore, the object to be thrown is thrown into a wide range in the front-rear direction and the left-right direction and is uniformly deposited.

【Example】

 FIG. 1 is a block diagram showing the construction of a drum type dispersing machine according to an embodiment of the present invention, FIG. 2 is a front view showing the mounting state of the diffusion blades of the drum, and FIG. 3 is showing the mounting state of the diffusion blades of the drum. A side view, FIG. 4 is a side view illustrating a loading state, and FIG. 5 is a front view illustrating a loading state.

Here, the drum type disperser 3 is used to uniformly disperse and throw in the object B to be thrown into the hopper 2 from the belt conveyor 1 in a wide range. It is installed immediately below the head pulley 4. In this drum type disperser 3, diffusion blades 7 for diffusing and discharging the input object B in the left-right direction are provided on the outer peripheral surface of the drum 6 which is rotated by the driving motor 5, with respect to the axis X of the drum 6. It is installed in the direction of inclination.

The drum type disperser 3 is provided with an inverter unit 8 and a sequencer 9 for controlling the rotational speed of the motor 5 for driving the drum, as variable speed control means for varying the rotational speed of the drum 6. . The sequencer 9 is equipped with an input unit 10 and a memory 11, and is required for control such as the properties of the object B to be charged, the range of the object to be charged, the magnitude and cycle of change in the rotation speed of the drum 6 for evenly charging the object. Various data are input in advance from the input unit 10 and stored in the memory 11.

When performing the loading operation, the loading target B is discharged near the drum 6 when the rotation speed of the drum 6 is low, and further forward from the drum 6 when the rotation speed is high. Therefore, the sequencer 9 outputs a control signal to the inverter unit 8 based on the data and the control program stored in advance in the memory 11, and the inverter unit 8 controls the rotation speed of the drum driving motor 5. . Therefore, the rotation speed of the drum 6 periodically changes within a predetermined range, and the charging target B is charged so as to be widely and uniformly dispersed in the front-rear direction. Further, the throwing object B is discharged by the diffusion blade 7 so as to be diffused in the left-right direction of the drum 6. Therefore, the throwing object B can be thrown into a wide range in the front-back direction and the left-right direction, and can be uniformly deposited.

When the amount and properties of the supplied object B to be supplied change due to load fluctuations of the belt conveyor 1 and other front-stage equipment, a detector 12 is provided in the front-stage equipment and the detection signal is provided. It is also possible to perform control in response to load fluctuations of the preceding stage equipment by sending to the sequencer 9.

[Effect of device]

 As described above, by using the drum-type disperser of the present invention, when an object to be charged is charged into a container, it can be charged in a wide range in the front-rear direction and the left-right direction and uniformly deposited. Therefore, it is possible to improve the volumetric efficiency when feeding it into the hopper, and when feeding the raw material into the melting furnace, it is deposited flatly, so it is easy to adjust the air volume at the tuyere, etc., and stable operation is possible. Become.
