は、抽出コンベヤ−の抽出量−により行なわれていた。One example of a silo that has the function of storing and discharging solid materials such as coal is the Atlas System silo. As shown in FIGS. 1 and 2, the silo consists of a silo body (shell) 1 and an extraction conveyor 2. It is composed of a delivery conveyor 3 and a sweep device (the sweep device referred to in the present invention is a general term for a sweep packet (4), a bull ring (5), and a drive device 116), and a drive device 6 rotates the bull ring 5. As a result, the sieve packet 4 automatically comes into contact with the stored coal 7 in the silo, scrapes the stored coal 7, carries it to the top of the extraction conveyor 2, and drops it into the conveyor. Since a discharge conveyor 3 is installed at the tip of the extraction conveyor 2 via a hopper 8, the coal 7 on the extraction conveyor 2 is discharged outside the silo through the discharge conveyor 3. The conventional control method for discharging coal from a silo having such a mechanism was based on the extraction amount of the extraction conveyor.

する。That is, the amount of coal loaded in the extraction conveyor case is detected, and the speed of the sweep bucket chain is adjusted and the onloff control of the sweep drive device is performed in accordance with the detection signal. However, in the above control method, since the amount of coal dispensed is controlled by the loading volume in the extraction conveyor nurse, the dispensed weight varies greatly depending on the apparent specific gravity of the coal.

ない場合における石炭払い出しは困難であった。In particular, the difference between lump coal and pulverized coal is so large that it becomes noticeable. With this kind of control, the amount of coal extracted becomes unstable9 or the sweep device repeats short-term intermittent operation, which can damage the sweep and icing motor and cause harm to other equipment (especially the conveyor). Give shadow. Additionally, in this control method, the sweep device operates for a certain period of time (usually about 40 seconds) as soon as a signal indicating the "extraction conveyor flow rate" is output, and after that time the sweep device stops, which is a repeated operation. , the time the sweep device operates is arbitrarily set depending on the sweep bucket chain speed and the capacity of the multiple (usually four) extraction conveyors. However, if this setting time is too long, the extraction amount becomes unstable as described above, such as excessive extraction. Furthermore, it has been difficult to increase the set time because it may overload the delivery conveyor or the like and cause trouble. Furthermore, when the remaining amount of coal in the silo is extremely small, the above-mentioned control causes a defect in which the extracted amount is reduced, so it is difficult to discharge the coal even when the coal storage lid is small, such as less than tfloOr/h.

イロ払い出し方法である。The present inventors solved the above problem, and also studied a method for discharging coal in a silo continuously and in a stable state,
A method of detecting the weight of coal on the dispensing conveyor by installing a Merrick detector (for details, refer to the Measurement Engineering Glossary (published by Ohmsha Shoten), etc.) on the dispensing conveyor, and controlling the dispensing of coal according to the detection signal. This discovery led to the present invention. That is, the present invention provides a method for extracting coal from a silo, such as the Atlas system, which has two or more extraction conveyors, a dispensing conveyor communicating therewith, and a sweep device, and a mechanism for transferring coal via the extraction conveyors to the dispensing conveyor by operation of the sweep device. When discharging coal, a Merrick detector is installed at at least one location on the discharging conveyor, the detector detects the weight of coal on the coal discharging conveyor, and the operating status of the sheave device is determined according to the detection signal. This is a coal silo discharging method characterized by controlling the number of operating extraction conveyors.

フンベヤ−。The method of the present invention is preferably used for the known Assilus system silo as described above, but what is particularly important in the control method of the present invention is that a Merrick detector is installed on the dispensing conveyor, The method is to detect the coal weight of the coal, and control the operating status of the sweep device and the number of operating extraction conveyors in accordance with the detection signal. The me and s quantities of the Merrick detector at this time may be appropriately selected from known ones depending on the type and amount of coal to be handled, and the installation location and location of the Merrick detector and extraction funnel.
スイープ装置の制御用電気配線等は上記要件を満たすも

す際にも有効である。According to the control method of the present invention, since the amount of coal discharged is constant, coal from silos with different amounts of coal can be mixed on the belt conveyor, and the number of bunkers can also be reduced. It is also effective when discharging not only coal but also grain.

ある。Hereinafter, the effects of the payout method of the present invention will be explained with reference to the drawings. FIG. 3 shows the control flow before the present invention. According to the seven seas, the amount of stored coal in the d1 silo is determined by the flow rate (bulk) detector 9 installed on the extraction conveyor 2.
It was controlled by the amount of coal. That is, the amount of coal in the extraction conveyor 2 is detected by the detector 9, and the detected signal is sent to the control device 10, and the sweep device 6 is controlled to turn on and off based on the difference from the coal extraction setting. At this time, the timer 11 for controlling the startup time of the sweep device [6]
-a (usually about 40 seconds) to keep the volume of the extraction conveyor 2 constant. In contrast, the present invention control 70- is shown in FIG. 4, but in addition to the conventional control method, in the present invention control method, a Merrick detector 13 is further installed on the dispensing φ dispensing conveyor 3, and the dispensing The weight of coal on the conveyor 3 is detected, and the difference between the weight based on the detection signal and the set value of the stone discharge weight is controlled by the control device 1o, and the sweep device 6 is operated by the control signal. Alternatively, the signal was sent to the operating extraction conveyor number control device 12 to also control the number of operating extraction conveyors 2. On this occasion,
By arbitrarily setting the timer 11-b for controlling the operation status of the sweep device 6 to be extended (for example, 5 minutes), the amount of coal discharged can be kept constant even when the amount of stored coal is small, and the extraction Since the number of operating conveyors 2 can be controlled at the same time, coal can be disbursed continuously and stably.
It becomes possible to take out. In addition, it is also possible to exclude the flow rate (volume) detector 9 and the control timer 11-a in FIG. 4.
