Description

Technical Field

[0001] The utility model relates to the technical field of gas stirring, in particular to a gas stirring machine for graphite. Background Art

[0002] Gas mixers introduce gas (such as air, nitrogen, etc.) into liquid or slurry and use the flow of gas to achieve material stirring and mixing. This stirring method is suitable for situations where it is necessary to avoid sparks, static electricity accumulation or potential explosion risks that may be caused by the use of traditional electric stirrers.

[0003] Since graphite needs to be sprayed for cooling during the forging process, graphite will precipitate and agglomerate when it accumulates at the bottom of the cabin for a long time. Manual stirring is required each time it is used, which greatly affects production efficiency.

[0004] The existing gas mixer cannot set the exhaust nozzle angle during operation, resulting in the graphite precipitation and agglomeration position not being exposed to gas. In addition, during the graphite precipitation and agglomeration process, it will adhere to the stirring blade, making it difficult to start the stirring blade. In addition, the traditional gas stirring component is in a set position in the stirring chamber, and as the material capacity increases, the amount of gas generated does not reach the stirring process. Therefore, the position of the gas stirring component cannot be adjusted according to the change in the capacity of the graphite in the stirring chamber. Utility Model Content

[0015] Beneficial effect: The utility model discloses a gas mixer for graphite. The utility model independently controls the rotation of the outer shaft and the inner shaft through the rotation of the first motor and the second motor, so that the inner tube rotates along the outer shaft and the outer tube rotates along the inner tube, thereby stirring the graphite that can be precipitated by stirring, and transmits the connected gas to the nozzle through the inner shaft, the cylinder and the inner tube through the air inlet to disperse the agglomerated graphite. According to the agglomeration position of the graphite in the stirring chamber, the rotation of the outer tube is driven by the inner shaft to control the angle of the nozzle. During the rotation of the outer tube, the diameter of the through hole will change, so that the air pressure of the nozzle will fluctuate, thereby realizing air pressure flow within different ranges in the stirring chamber. The increase in graphite capacity makes stirring difficult, and then the outer shaft is moved in the stirring chamber by moving the cylinder to adjust the height at which the inner tube can rotate along the outer shaft.

DETAILED DESCRIPTION

The connected gas is transmitted to the nozzle through the inner shaft, the cylinder and the inner tube through the air inlet to disperse the agglomerated graphite. According to the agglomeration position of the graphite in the stirring chamber, the rotation of the outer tube is driven by the inner shaft to control the angle of the nozzle. The scheme is described in detail through specific embodiments below.
