Description

Technical Field

[0001] The utility model relates to the technical field of cement production, in particular to a calcining line preheater decomposition furnace structure which can prevent blockage. Background Art

[0002] Materials are easily accumulated in a 2.1-meter-wide section at the gooseneck top of the preheater decomposition furnace in the first-line firing process, resulting in increased wind resistance and poor ventilation, which increases the speed of the high-temperature fan by 20rpm and the power consumption of the clinker unit by 0.3KWh / t. Materials frequently collapse in the five-stage cyclone, restricting the output of the rotary kiln and causing a process accident in which the cone of the five-stage cylinder and the discharge pipe are blocked.

[0003] The existing referenceable Chinese utility model patent has a publication number of CN219735981U, which discloses an anti-scaling preheater decomposition furnace, and relates to the technical field of decomposition furnaces. The utility model includes a furnace body, a top cover, and a mounting plate. The interior of the furnace body is a cavity structure. The top cover is embedded in the upper surface of the furnace body, and the mounting plate is embedded in the upper surface of the top cover. The upper surface of the mounting plate is embedded with a constriction, which is connected to the interior of the furnace body. The mounting plate and the top cover are movably connected. Microcrystalline plates are embedded in the circumferential side surfaces of the interior of the furnace body, and mounting rods are embedded in the circumferential sides of the upper surface of the mounting plate. One end of the mounting rod penetrates the upper surface of the mounting plate, and one end of the mounting rod is snap-fitted with the top cover. The utility model reduces wall crusting by removing the original castable and adding a microcrystalline plate, which effectively reduces wind resistance and ensures the overall smooth operation of the system.

[0004] Based on the search of the above patents and combined with the equipment in the prior art, it was found that the gooseneck top of the preheater decomposition furnace in the firing line is 2.1 meters wide, and the original decomposition furnace gooseneck is an arc-shaped structure, which makes it easy for subsequent materials to accumulate, resulting in increased wind resistance and poor ventilation. Material collapses frequently in the five-stage cyclone, restricting the output of the rotary kiln and causing process accidents such as blockage of the five-stage cylinder cone and the discharge pipe. When materials accumulate on the gooseneck, it is easy to cause the gooseneck to collapse, resulting in the subsequent inability to continue to use. The existence of these problems has affected the use of the device. Utility Model Content
