Description

one

This invention relates to the field of moisture measurement of bulk materials.

A device for determining the moisture content of materials by hydrostatic weighing of dry and wet bulk material is known.

However, the measured sample of the bulk material is manually changed and each time and the measurement is washed out with the previous sample.

To reduce the analysis time and increase the accuracy of measurement of humidity in the proposed moisture meter, the vessel with the test substance is equipped with a movable bottom connected by means of a shaft-lever gear with an engine, and the water tank in the upper part has an overflow channel.

The moisture meter consists of a bunker / ra 1, an autosampler 2, an automatic porpion dispenser 3, an internal vessel 4 for weighing sand in water, a vessel suspension 5 to the weighing mechanism, a lid-bottom 6 secured at the hinge 7. The lid is closed with the help of a spring 8 and can automatically open, with the help of a reversing electric motor 9, to the axis of which a screw 10 with a nut 11 is attached.

The ha ha 12 has a fork at its end, which rests on the finger of a lever 13 pivotally attached to the middle of the lid, and is held in a raised position at an acute angle to the lid by means of a spring 14. The vessel 4 can hang in a free state when it is raised. Restricting stops are attached to limit the buildup of the vessel when the lid is opened on the inside of the external vessel against the hanging vessel. The moisture meter works as follows.

The sample of the material under study from the bunker 1 according to a specific program is taken by the automatic sampler 2, then it goes into the automatic portioning dispenser 3, where the weight portion is tested.

The spent weighing portion is conveyed to vessel 4 for weighing sand in water. Cover 6 is closed at this time. After weighing the weight portion in water, the arrow of the weight measuring mechanism deflects in proportion to the moisture content and gives a moisture reading.

After weighing, the lid 6 opens automatically with the help of the electric motor 9, the screw 10 rotates, the nut 11 moves down with the thrust 12. The thrust fork presses the thumb of the lever 13. The lever turns the lid, it opens and sand is poured out. The accumulated sand in the outer tank is cleaned periodically once a shift. The bottom 15 of the outer vessel is made

film set. Water is first drained and then the bottom is removed with sand for cleaning. In the upper part, the vessel has a drain pipe 16, through which as it is filled with sand, excess water can drain.
