Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for measuring the moisture content of materials that allows the moisture content of materials to be measured easily and quickly.

Conventionally, the moisture content in materials has been measured using various methods, but each company uses its own method.Generally, the materials are suspended in a test hook, and after certain conditions, the materials are measured. The previous method used a primitive method of taking out the sample and quickly measuring it to determine the moisture content. i2, which was a problem because it was dependent on external conditions and measurement errors were likely to occur. For example, when taking out materials, the temperature and humidity inside the box may change, the material taken out may change due to the outside temperature and humidity, or even if the air inside the box is forcibly circulated to °C, the temperature inside the box may change. There were temples of the gods where it was impossible to make the temperature and humidity completely uniform, and variations in temperature depending on the location were unavoidable.

Therefore, the inventors did not take the sample outside,
Moreover, as a result of testing countless divine methods to quickly determine the moisture content in materials, we finally arrived at the present invention. That is, the characteristics of the present invention are that an arm that can be moved, stopped, and lowered is provided in a hook that can be humidified and dried, and that a food hanging tool VF is attached to the arm while the arm is suspended. The object of the present invention is to provide a method for measuring humidification and dry moisture content by lowering the suspension, releasing the sagging of the suspension described in 61j, and then measuring it with a scale.

Next, we will explain an embodiment of the apparatus for carrying out the present invention with reference to FIGS. 1 to 3, and then describe the structure of the present invention.

The material (omitted) is a material hanging tool (3) V"CS-, and the material hanging tool (3) is normally hung from the arm (4). , anti-slip tool (
16) prevents it from moving back and forth. This arm (4) is attached to the mandrel (5) using the mandrel (5) as a fulcrum so that it can be lowered at least to the position where the hanging tool is suspended, and a spring +61 is attached to it to return it to its original position after descending at t1. . In this example, there are two arms (4) on the left and right sides, but there may be four arms (4) and eight arms (8 arms) as appropriate. In order to lower the arm (4), a presser (7) is attached to the par (2).
) are arranged in parallel, and the presser foot (7) is connected to the handle (8).
) in the direction of the arrow in Figure 1, the spring (9) will stretch, and the presser (7) will be in the state shown in Figure 2.
presses the arm 14), and at least the hanging position of the hanging tool of the arm (41) is lowered.
1) @ (121) Place the mortar in a recessed manner @ Arm (4)
The hanging state is released from jfl and the hanging tip (15)
floats off the arm and becomes free. At this time, use a weighing device (
1O) displays the vehicle weight of the material hanging tool (3) and the material (omitted).Also, subtract the weight of the material hanging tool. After that, when it is placed on the handle (8), the presser (71) returns to the 11-1 position due to the action of the spring (9), and at the same time, the arm (4)
The ratio returns to 11:1 due to the action of the spring (6). The arm (4) is rotatable, making it easy to carry out the above operations and measure the weight of materials when necessary.
The above devices are attached to the box (1) 71. and
As shown in Figure 3, there is a peephole (step) in front of the window.
) All you have to do is operate the handle (8) attached to the outside. Box (1) is designed in-house for humidification and drying. Check the humidification and dryness conditions! , just measure the amount of material N and find the moisture content in the material when necessary. At this time, by making the arm freely rotatable, it is possible to prevent humidification and dry spots in the material, and also to prevent humidification, dryness, dampness, etc.
Hemostasis can be controlled by each generator of cold and hot air.
It is best to forcefully blow in and circulate the air, or just stop the air blowing and circulation during weighing. The box is in an insulated state G401 to prevent dew condensation from occurring in high temperature and high humidity conditions, allowing stable measurement over a long period of time. Any weighing device may be used, but for example, it is effective to use an automatic weight balance (21) with a unit of 0.01 to Q, OO1gr. or! B has a large diameter so that they do not come into contact with each other. Only the data table (Ill) is connected to the inside of the box, so weighing can be done externally, and the arm (4) can be lowered manually or mechanically.The mandrel (5) It is rotated at a constant speed by a motor 07), and can be stopped, for example, right above the data table of a weighing instrument when necessary.

The above are preferred embodiments for carrying out the present invention,
The present invention is not limited to such embodiments, and can be implemented in one-chamber embodiments.

The box according to the present invention may be any suitable box, and is not particularly limited as long as it is equipped with a heating and drying mechanism.

-Also, regarding the lowering mechanism of the arm that can be lowered freely, lfh
6 Artificial or mechanical J-Anything is fine. rotation of the arm,
Stopping may be done either manually or mechanically, and it is more preferable to incorporate an electric circuit into a mechanism that allows stopping at the weighing location when necessary. As for the document hanging tool, it can be removed from the arm in a private room, and of course it can be done mechanically and automatically. As for the weighing device, J-yen scale is fine, but if you value accuracy, it is better to use a more precise large bottle or the like.

The present invention can also be implemented as shown in FIG. In other words, the state in which the material hanging tool (3) is suspended by the arm (4) in Fig. 4 is the same as in Fig. 1, but the arm (4) has descended to the chain line position as shown in Fig. 82. When the hanging tool (
The tip (15) of 3) will be held A2. If this key member is directly connected to a scale outside the box, the weight of the material (omitted) and the material hanging tool will be measured by the scale.
As in the previous embodiment, the weight of the mass can be known from the outside, and the moisture content of the material can be easily determined by n.

In this case, it goes without saying that the key member (24) may be used in the gallery as long as it is made to hang the document hanging tool (3). In order to determine the moisture content in the material, for example, the weight (A-) in an absolutely dry state and the weight (B) in a humidified state may be calculated using the following formula.

-A Moisture content = □ X I OO (%) At this time, by the method of the present invention,
