Description

Technical Field

[0001] The utility model relates to the technical field of detection equipment, in particular to a graphite content measuring instrument. Background Art

[0002] During the preparation of graphite materials, the graphite block materials need to be dried. In the moisture testing stage, a hygrometer is needed to test the humidity in a sealed box. There is a drying box in the sealed box. The graphite block is placed in the drying box for drying, and then the humidity in the sealed box is tested with a hygrometer. When the sealed box is opened, the water vapor in the box will condense into water droplets on the inner wall of the sealed box when it is cold. The next time the graphite block is dried, the water droplets on the inner wall of the sealed box will evaporate again, increasing the humidity in the sealed box and affecting the test data, thereby affecting the moisture detection of graphite drying. In addition, the existing graphite content testing device is difficult to quickly dry the graphite content during the test, which delays the test efficiency.

[0003] In order to solve the deficiencies of the existing technology, people have conducted long-term exploration and proposed various solutions. For example, a Chinese patent document discloses a graphite drying moisture test device [CN202321261418.9], which includes a sealed box, a pressure plate is installed at the opening of the sealed box, a hygrometer is fixedly connected to a position on the left side of the upper surface of the pressure plate, a cylinder is installed at the middle position of the four edges of the upper surface of the pressure plate, the movable end of the cylinder extends into the sealed box and is fixedly connected to a rectangular sleeve, a side of the rectangular sleeve is horizontally provided with an insertion hole, a stud is inserted in the insertion hole, and one end of the stud close to the inner wall of the sealed box is fixedly connected to a wiper, a drying box is fixedly installed on the lower surface of the sealed box, a heating plate is fixedly installed in the drying box, and a plurality of through holes of the same size are evenly opened at the edge of the lower surface of the sealed box, the lower end of the sealed box is fixedly connected to a water tank, and a position on the lower left side of the water tank is threadedly connected to a water outlet valve.

[0004] The above solution solves the problem in the prior art that the humidity in the sealed box of the graphite testing device easily affects the accuracy of the test data to a certain extent.
