Description

Technical Field

[0001] The utility model relates to the technical field of graphite drying, in particular to a graphite drying kiln. Background Art

[0002] In graphite production, two methods are usually used to obtain high-purity graphite, namely high-temperature purification method and mixed acid purification method. Since the high-temperature purification method consumes a lot of energy, the mixed acid purification method is more commonly used. However, the high-purity graphite obtained by the mixed acid purification method is a wet material and must be dried before it can be stored and used. Usually, a kang, drying kiln or other drying device is used for drying.

[0003] For example, a Chinese patent with publication number CN207763386U discloses a graphite drying kiln, including a kiln body, a kiln car, tracks, a material tray and a stirring device. A plurality of tracks are provided at the bottom of the kiln body, and a plurality of kiln cars are arranged in the kiln body through the tracks. The kiln car includes a plurality of columns and cross plates. The columns are vertically arranged on the kiln car, and the cross plates are laterally connected to the columns. A groove is provided on the cross plate. Both sides of the bottom of the material tray are provided with protrusions. The protrusions match the grooves so that the material tray is arranged on the cross plate. The stirring device includes a pillar, a pillar seat, a first linear motor, a slider, a second linear motor and a steel rake. The first linear motor is arranged between every two kiln cars, and the pillar seat is arranged on the slide seat of the first linear motor. The pillar is arranged on the pillar seat, and a plurality of sliders are provided on the pillar. Second linear motors are respectively provided on both sides of the slider, and a steel rake is provided at the bottom of the slide seat of the second linear motor. The utility model is convenient for loading and unloading graphite, and the graphite can be stirred evenly by the steel rake, thereby improving the graphite drying efficiency.

[0004] The technical solution recorded in this scheme is to drive the pillar to move longitudinally along the gap between the two kiln cars through the first linear motor, and then set the steel rake in the graphite powder on each material tray by moving the slider on the pillar, and then drive the steel rake to move along the lateral direction of the two kiln cars respectively through the second linear motor, so that the steel rake can finally stir the graphite powder on all material trays of the two kiln cars. However, in this scheme, the pungent gas generated during the drying process is directly discharged into the air without treatment, which is not conducive to environmental protection. At the same time, in this scheme, the hot air is inside the kiln, causing the trays on which the materials are placed to carry heat after being dried by the drying kiln. If the materials need to be taken out in time after drying, improper operation may easily cause scalding to the workers. Utility Model Content

[0005] The utility model aims to provide a graphite drying kiln to solve the problems in the above-mentioned background technology that the tray carrying materials in the drying kiln carries heat during the material taking process and easily causes burns to personnel, and the pungent gas generated during the drying process is directly discharged without being treated.
