Description

Technical Field

[0001] The utility model relates to the technical field of vertical kilns, in particular to a sealing feeding structure for vertical kiln production. Background Art

[0002] Vertical kiln refers to thermal equipment that continuously calcines clinker with upper loading and lower discharging. It consists of kiln body, loading and discharging device and ventilation equipment. It is widely used to calcine various refractory raw materials and lime. Its advantages are low infrastructure investment, small footprint, high calcination efficiency, low fuel consumption and easy mechanization and automation. Vertical kiln has a long history of application in refractory industry. The ancient natural ventilation vertical kiln is shaped like a bottle, commonly known as bottle kiln, which is the predecessor of modern vertical kiln. In the 1960s, the structure and operation of vertical kiln were significantly improved. The calcination of dolomite magnesia vertical kiln uses vaporization cooling wall instead of refractory brick lining to solve the problem of sticking kiln. The material sealing device is adopted, and the discharge can be kept windless, which creates conditions for realizing the automation of the operation of the whole kiln system. The utilization coefficient is also greatly improved, but the current vertical kiln charging structure does not have the function of sealed charging, which leads to the easy loss of heat during the charging process, affecting the use, and does not have the function of dust removal, which leads to the dust generated during the charging process flying around and affecting the surrounding environment. For this reason, we propose a sealed charging structure for vertical kiln production. Utility Model Content
