Multi-bin rotary kiln

Abstract

The invention provides a multi-chamber rotary kiln, which includes a rotary drum, a heating device and an air induction device. A partition extending along the axial direction of the rotary drum is arranged inside the rotary drum, and the partition divides the rotary kiln. The inner space of the cylinder is divided into two or more disconnected chambers, each chamber is equipped with a lifting plate on the inner wall of the rotary cylinder, the heating device is installed at one end of the rotary cylinder, and the air induction device Installed at the other end of the rotary cylinder, the heating device heats the materials in each chamber, and the air induction device cooperates with the heating device to dry the materials. In the present invention, the internal space of the rotary drum is divided into multiple chambers, and each chamber operates independently, so that the utilization rate of the internal space of the rotary drum can be improved, and each chamber raises the material separately, the depth of the material becomes shallower, and the material The landing space becomes smaller, so that the drying efficiency is greatly improved and the damage rate of materials is reduced while the external dimensions of the rotary kiln remain unchanged.

Description

technical field [0001] The present invention generally relates to a rotary kiln, and in particular, relates to a multi-chamber rotary kiln for improving drying efficiency. Background technique [0002] At present, in the field of calcium carbide production, there is a process of drying semi-coke. In the existing semi-coke drying process, a rotary kiln is usually used to rotate and raise materials for drying. However, the interior of the existing rotary kiln is a cylindrical space. Because it needs to be lifted, the material cannot be filled too much, and the thickness of the material is too large, which makes the bottom material difficult to dry. efficiency needs. In addition, during the lifting process, due to the large falling space of the material, it is easy to cause damage to the material, and the damage rate is high. Finally, when the rotary kiln rotates, the eccentricity is large, which requires large support and power, which objectively increases the cost. Theref...

However, the interior of the existing rotary kiln is a cylindrical space. Because it needs to be lifted, the material cannot be filled too much, and the thickness of the material is too large, which makes the bottom material difficult to dry. efficiency needs

In addition, during the lifting process, due to the large space for the material to fall, it is easy to cause damage to the material, and the damage rate is high

Finally, when the rotary kiln rotates, the eccentricity is large, which requires large support and power, which objectively increases the cost
