The invention discloses a vertical lime kiln and belongs to the technical field of lime production. The vertical lime kiln comprises a furnace, a main grate, side grates and a blast pipeline, wherein an ash discharging hopper is arranged on the lower portion of the furnace, an ash discharging bin is arranged under the ash discharging hopper, an ash discharging inlet of the ash discharging bin is connected with the ash discharging hopper, a lime transport device is installed below an ash discharging outlet, the main grate is in a quadrangular prism structure and fixed under the furnace, the side grates are fixed around the main grate, an ash discharging channel leading to four directions is formed between the main grate and the side grates respectively, an ash discharging trolley assembly is arranged below each ash discharging channel in each direction, a guide rail is arranged under each ash discharging trolley, and a trolley plate of each ash discharging trolley assembly is fixedly connected with a crankshaft connecting rod seal cover assembly which is connected with a motor speed reduction assembly. The vertical lime kiln mainly solves the technical problem that large lime blocks are prone to blocking ash discharging channels.
Description
technical field [0001] The invention belongs to lime production equipment, in particular to a vertical lime kiln. Background technique [0002] The lime kiln includes a hearth, ash unloading hopper, ventilation equipment and a grate. A side grate is fixed at the outlet of the hearth. The traditional lime kiln grate is a conical truncated structure welded by several steel pipes. The grate Located in the lower part of the furnace, a narrow annular lime channel is formed between the furnace chamber and the bottom of the grate. This structure can pass through smaller and more uniform lime blocks; however, the lime is calcined in the furnace. There are often large lime blocks sintered into one body in the furnace, and the large lime blocks are stuck at the annular ash outlet channel, which blocks the falling of the upper lime, which leads to different calcining times of lime in different areas of the furnace, so the lime produced is not uniformly calcined. Lime quality is diffic...
