る。As a silo for storing powder and granular materials, JP-A-58-1702
Those disclosed in Publication No. 1 and the like are publicly known. As shown in FIG. 3, this type of silo is equipped with a container having an upright cylindrical side page l, and a disk column 2 for carrying out is erected at the center of the container. The lower end of the disk column 2 serves as an outlet 3. A screw conveyor device 4 is horizontally suspended between the disk column 2 and the side wall 1 from above the container 1, and is capable of vertical movement and horizontal rotation.

In order to do this, the screw conveyor device 4 is reversed and the material is sent from the outer peripheral side to the disk column 2 side, and is carried out through the inside of the disk column 2, the outlet 3, the screw conveyor 11, and the conveyor 12. 13 is the upper surface of the powder material.

たままで、払出されない。If the powder or granular material stored in the silo is sticky, it will solidify, so when discharging the powder or granular material that is not in contact with the screw of the screw conveyor device 4, it remains fixed to the silo. That is, between the inner wall la of the silo 1 and the screw of the screw conveyor device 4, there are 20 to 30
Although there is a gap of cm, the powder remains stuck to the inner wall 1a and is not discharged.

る。As the discharging progresses, the lower surface of the granular material 13 descends, so that the undischarged granular material stands at a height of several meters with a thickness of 20 to 30 cm. In this state, it is conceivable that it will collapse due to some kind of vibration and fall onto the screw conveyor device 4. When this happens, recovery is difficult.
本発明の目的は、サイロの内壁に固着した粉粒体を払出
しできるようにすることにある。An object of the present invention is to enable powder and granular material stuck to the inner wall of a silo to be discharged.

する。[Means for Solving the 8 Problems] The present invention provides a method for attaching a vertical shaft to the screw conveyor device near the inner surface of the silo side wall on the rear side in the turning direction when the screw conveyor device is operated for discharging. It is characterized by a propeller that rotates at the center.

半径方向に移動可能に設置している。An embodiment of the present invention will be described below with reference to FIGS. 2 and 3. A disintegrating device is installed at the rear end of the screw conveyor device 4 for discharging powder and granular material, near the side Mla. The disintegration device is one in which a large number of propellers n are provided on a vertical shaft n rotated by a motor 21. When viewed from the axial direction, multiple propeller units are installed around the circumference, and when viewed from the radial direction, they are installed at different heights. The propeller n is capable of cutting off the remaining part that is not delivered by the screw conveyor 45 and is stuck to the side Wtla. The disintegration device (a) is installed on the frame 4a of the screw conveyor device 4 so as to be movable in the radial direction of the siloe.

位置調整を容易に行うことができるものである。According to such a configuration, a separate disintegration device is included! Since the installation position can be adjusted toward (2), the propeller part can be installed in the vicinity of a position where it does not hit the side wall 1a, so it is possible to reduce the remaining L notch 7:30 that is fixed to the side wall 1a. Since each disintegrating device is small, the position of each disintegrating device can be easily adjusted when assembling the silo.

ヤ装置４力ｔＩＢ回した後に払出される。The disintegration device is the screw conveyor device 4 during dispensing work.
It is installed at the rear end in the turning direction. For this reason, the powder and granules collapsed by the rotation of the propeller bar are discharged after being rotated by the screw conveyor 4 times tIB.

ので、払出されないで側！！ｌａに固着している粉粒体
の高さをより低くでき、スクリューコンベヤ装置４への
崩壊をより少くできるものである。For this reason, since it is only necessary to disintegrate the remaining material that has not been discharged by the screw conveyor 4, the disintegration device can disintegrate the propeller bar near the upper surface 13 of the powder as shown in Fig. 2. , it is possible to reduce the power of the motor 21. Since it is possible to prevent dust from near the upper surface 13 of the powder and granules, the height of the powder and granules that are stuck to the side !!la without being ejected can be reduced. It can be made lower, and collapse into the screw conveyor device 4 can be reduced.

て邪魔にならないものである。On the other hand, during powder loading operation, the screw conveyor device 4 rotates in the opposite direction. Therefore, the disintegration device is located at the front end in the rotating direction, and even if the propeller n is installed near the top surface of the powder and granules, it will not interfere with the powder and granules being stacked. .
本発明によれば、スクリューコンベヤ装置で払出されな

ものである。According to the present invention, it is possible to reduce the height of the powder that remains on the inner wall of the silo without being discharged by the screw conveyor device.
This can prevent accidents such as the screw conveyor device being buried.
