Description

Technical Field

[0001] This utility model relates to the field of tank calcining furnace repair technology, specifically the structure of a special hot repair spraying machine for tank calcining furnaces. Background Technology

[0002] A carbon calcining pot furnace is a thermal device that indirectly heats carbon materials within a fixed calcining pot to complete the calcination process. It is a widely used furnace type in the carbon industry. During calcination, the raw material is added to the pot through a top-feeding device and gradually heated by flues located on both sides of the pot as it moves downwards. The heat generated by the combustion of fuel in the flues is indirectly transferred to the raw material through the flue walls. When the temperature of the raw material reaches 350–600℃, a large amount of volatile matter is released. This volatile matter is collected through a volatile matter channel and sent to the flues for combustion. The combustion of volatile matter is a process that occurs in a calcining pot furnace. A calcining furnace is a heat source; after the raw materials undergo a series of physicochemical changes at temperatures above 1200-1300℃, they enter the water jacket for cooling from the bottom of the tank and are finally discharged from the furnace by the discharge device. Tank calcining furnaces are industrial equipment with a large initial investment. For example, the cost of a single 24-tank calcining furnace is around 3 million yuan, and the cost of the commonly used 80-tank calcining furnace is even more expensive. Although its design life is 5-8 years, due to various factors, it is not uncommon for small fire spots the size of beans to appear on the tank walls after only two years of operation, requiring repairs.

[0003] The existing CN211739877U describes a hot-state repair device for burn-through cavities in a carbon tank calcining furnace. This device utilizes a combination of water and air cooling to address the challenges of high-temperature construction within the furnace. It is primarily designed for repairing cavities of various sizes without shutting down the furnace, allowing for same-day material replenishment and production resumption. However, it has shortcomings: the existing equipment suffers from poor spraying effect, inadequate protection, poor storage, and inconvenience. Therefore, a dedicated hot-repair spraying machine for tank calcining furnaces is needed to address these issues. Utility Model Content
