本発明は、コーンをもつサイロに貯蔵されている粉粒体
などの貯蔵量測定方法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for measuring the amount of powder or granules stored in a silo with a cone.
従来、内部にコーンをもつ大型サイロ内に貯蔵されてい

多く必要となシ、また測定方法が断続的で測定にかな９
の時間を要するばかシでなく精度を欠くなどの問題点が
ある。Conventionally, the mainstream method for measuring the amount of powder and granules stored in large silos with internal cones has been to use a hanging type to measure the surface level of the stored material. As for the measurement method, as the silo becomes larger, many measurement points are required, and the measurement method is intermittent, making it difficult to measure.
There are problems such as not only is it time consuming, but it also lacks precision.
本発明は、このような実情に鑑みなされたもので、簡単

。The present invention was made in view of the above circumstances, and solves the conventional problems by simple and rational means.
The amount of strain in the steel support that supports the cone is measured using a strain meter, and the total storage amount is determined by correlating this measured value with the storage amount of the calibration curve unique to that silo. The purpose of this invention is to provide a highly accurate storage amount measurement method.

測定値の平均値を求めるようにしたものである。Next, an apparatus for carrying out the measuring method of the present invention will be explained with reference to the drawings. In the figure, the entire weight of the cone (2) provided inside the silo body (11) is supported by a cylindrical steel support (3). One or more strain gauges (4) are provided, and the strain gauges (4) are connected to an analysis device. In addition, Figure 12 shows the cone (2) connected to multiple steel supports (3α
), a strain gauge (4) is attached to each support (3α), and each strain gauge (4) is connected to an analysis device (3α).
This method calculates the average value of the measured values.

は当然である。The characteristic curve diagram shown in Figure 3 is a calibration curve unique to each silo, with strain amount on the vertical axis and storage amount on the horizontal axis. This is a graph showing the correlation between the amount of strain on the support (3) or column (3α) and the storage amount when a set amount of granular material (coal or grain) is introduced into the silo. Naturally, the calibration curve will be different for each.

In addition, the signal from the strain meter (4) is output as an analog value, and a human determines the storage amount using a calibration curve.

The stored amount can be known continuously at all times, and there is no need to measure with a hanging surface level meter each time as in conventional technology. It has an excellent feature of measurable improvement.
