に係わるものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a moisture measuring device for powder or granular material and a method for measuring moisture in powder or granular material using the device. In particular, the present invention relates to a moisture measuring device for powder and granular material being transported by a conveying device and a method for measuring the moisture content of powder and granular material using the device.
［従来技術１
非接触近赤外線水分計を用いて粉粒体の保有する水分を
測定することは従来から知られている。[Prior Art 1] It has been known for a long time to measure the moisture content of powder particles using a non-contact near-infrared moisture meter.
このような水分計は一般に、測定視野となる粉粒体の最
上表面における水分を測定するものである。Such a moisture meter generally measures moisture on the uppermost surface of a powder or granular material, which is the measurement field of view.

置も提案されている。However, the moisture value on the uppermost surface of the granular material changes significantly over time, and there is a large error between the measured value and the actual average moisture value of the granular material. In particular, when this powder or granular material is transported over a relatively long distance or for a long time by a conveyance means such as a belt compare, the moisture content is measured using a non-contact near-infrared moisture meter installed near the outlet end of the conveyance means. A large error occurs between this value and the actual average-moisture value possessed by the powder or granular material. Therefore, in order to obtain a moisture value close to the actual average moisture value, the non-contact near-infrared moisture meter is placed at the position where the average moisture value of the powder or granules on the conveyor is exposed. A moisture measuring device has also been proposed that is equipped with a scraping plate to measure the moisture content.

落下し、作業環境が汚染されるといった問題がある。[Problems to be Solved by the Invention] In the moisture measuring device having the above structure, the scraper plate is provided almost perpendicularly to the conveying direction of the powder and granules, and for example, when conveying the powder and granules on a conveyor belt. It is a fixed type whose height can be adjusted manually depending on the Mf4 or its bulk. Therefore, due to variations in the weight, bulk, etc. of the powder and granular material loaded, the distance (level) between the top surface and the non-contact near-infrared moisture meter varies, making it difficult to perform follow-up measurements, and the actual measured value and actual moisture content may vary. There is still some error in the values. Furthermore, since the plate of the scraper is fixed, there is a problem in that when a large amount of powder is loaded, powder and granules fall over the belt, contaminating the working environment.

Incidentally, in the figure, a dashed line indicates a signal circuit. In the figure, 1 is a detector (note) that continuously detects the bulk level or weight of the powder or granular material 3 loaded on the conveyor bell 1-2 and being transferred in the direction of the arrow, and sends a detection signal to the controller 4. : In FIG. 1, the case where the detector is a bulky level detector is illustrated. In the case of weight detection, this is only used in place of a belt scale, so it is not shown. 5 is a moisture measuring unit supported by a support arm (not shown), which straddles the middle of the conveyor belt 2 in a tunnel shape, is surrounded by a cover 7 reinforced by a framework 6, and inside the conveyor belt 2, a level adjustment pedestal 8 is provided along the running direction at approximately the center. As shown in the enlarged plan view of FIG. 3, for example, finned rollers 9.9 are attached to the level adjustment pedestal 8 at its front end and rear end in the direction in which the conveyor belt 2 runs. The level adjustment base 8 itself can move up and down while maintaining its horizontal state by rotating along guide columns 1o, 1o vertically fixed to the framework 8. Reference numeral 11 denotes a leveling tool for smoothing the surface of the powder or granule material 3 on the conveyor belt 2, and 12 is arranged behind the leveling tool 11 for measuring the moisture content M of the powder or granule material 3 leveled by the leveling tool 11. These non-contact near-infrared moisture meters are fixedly mounted on a level adjustment base 8 facing downward. For example, as shown in the enlarged perspective view of FIG.
The tip part 1ffa is oriented so as to face the running direction of the conveyor belt 2, and has a bow-like shape with surfaces 11b and 11C that scrape through the powder and granular material 3 to expose the inside, and a leveling bottom surface 11d. It consists of a pentagonal prism. In addition, the non-contact near-infrared moisture meter 12 has a function of transmitting the moisture on the exposed surface of the powder material 3, which is within its optical field of view and has been leveled by +2 by the leveling tool 11, to the controller 4 as an electric signal. .

A wire 14 that is vertically movable is connected to the cover 7 by penetrating it. Based on the detection signal from the detector 1, the controller 4 instructs the power cylinder 13 to move the rod 13a forward and backward, controls the vertical movement of the level adjustment table 88, and also controls the movement of the level adjustment table 88 from the non-contact near-infrared moisture meter 12. It has a function of calculating the moisture content of the powder or granular material 3 based on the electrical signal and instructing a moisture display device (not shown) to display the measured value.

に引き上げられる。Next, a method for measuring the moisture content of powder or granular material using the moisture measuring device of the present invention will be described. A conveyance device, for example, a conveyor belt 2 is a drive drum (
(not shown), the vehicle is driven in the direction of the arrow at a constant or variable speed. The bulkiness level (or weight) of the loaded and moving powder or granular material 3 per unit distance of the conveyor belt 2 is detected by the detector 1 and transmitted as a detection signal to the controller 4, and the controller 4 detects this. Based on this, the power cylinder 13 is commanded to move the rod forward and backward. For example, when the loading level of the powder or granular material 3 is bulky, the rod of the power cylinder 13 is moved back in response to a command from the controller 4, and the level adjustment pedestal 8 is pulled up to a certain level position by the wire 14.

ルトオーバーの問題も解消される。As a result, the leveling level of the leveling shell 11 also increases, and the leveling level of the leveling shell 11 increases, and the leveling level of the leveling shell 11 increases, and the leveling level (on the surface 1 lb, 11C, on the leveling bottom surface 11d,
The resistance to the transfer of the powder 3 is reduced, the inside of the powder is exposed, and the exposed surface is smoothed. In other words, falling of the powder or granule 3 from the conveyor belt 2 due to the collision between the powder or granule 3 being transferred and the leveling tool 11 can be avoided to the maximum extent possible, and moisture on the exposed fresh internal surface can be removed without contact. Continuously measured using a near-infrared moisture meter. The measured value is then transmitted as an electrical signal to the controller 4, where it is calculated and commanded to continuously display the moisture value on a display device (not shown). Conversely, for example, if the loading level of the powder or granular material 3 is low as detected by the detector 1,
In response to a command from the controller 4, the rod of the power cylinder 13 moves forward, and the level adjustment pedestal 8 is lowered to a fixed level position by the wire 14. As a result, the leveling level of the leveling tool 11 is also lowered, and the leveling level of the leveling tool 11 is reduced by
, 11c, the leveling bottom surface 11d reduces the resistance to the transfer of the powder or granule material 3 while exposing the inside of the powder or granule material, and does not scratch the surface thereof. The moisture content on the leveled surface is continuously measured using a non-contact near-infrared moisture meter. The measured value is then transmitted as an electrical signal to the controller 4, where it is calculated and commanded to continuously display the moisture value on a display device (not shown). As described above, the level adjustment pedestal 8 moves up and down in response to changes in the bulk or weight of the powder or granular material 3 transferred by the conveyor belt 2, and therefore, the leveling tool 11 fixed thereto is moved. Although the contact near-infrared moisture meter 12 moves up and down at the same time, the level difference between the leveling bottom surface 11d of the leveling tool 11 and the non-contact near-infrared moisture meter 12 is constant, so that the powder grains leveled by the leveling bottom surface 11d remain constant. Non-contact near-infrared moisture meter 1 on exposed surface of body 3
Since the optical viewing distance with respect to 2 is always constant, the moisture measurement results are even more accurate. In addition, as described above, since the leveling tool 11 moves up and down in response to variations in the bulk of the powder or granular material 3 to be transferred or the amount of M, belt overflow of the powder or granular material 3 during the leveling operation is prevented. The problem will also be resolved.

The present invention provides a moisture measuring device for IC powder and a method for using the same, and has great industrial utility value.
