Description

Technical Field

[0001] The utility model relates to the technical field of annular furnaces, in particular to a rotation limiting device for the bottom of annular furnaces. Background Art

[0002] When the annular furnace rotates at the bottom, centrifugal force will be generated due to inertia. In order to prevent the bottom from deviating from the set trajectory when rotating, the bottom of the furnace is limited to overcome the centrifugal force of the bottom of the furnace. In the prior art, most annular furnaces currently use hydraulic mechanisms and pneumatic mechanisms to meet the limiting requirements. However, the installation of hydraulic mechanisms requires the addition of hydraulic stations, and the installation of pneumatic mechanisms requires the addition of compressed air sources. These equipments also need to be regularly repaired and maintained, which increases investment costs and operating costs, and is not conducive to actual production. To this end, we propose a rotation limiting device for the bottom of an annular furnace. Utility Model Content
