AI Technical Summary
In the magnesium smelting process of the Pijiang process, the free ammonia introduced after the magnesium slag is used in the batching is easily desorbed and volatilized during the raw material crushing process, resulting in excessive ammonia escape from the kiln tail exhaust gas, which poses a great environmental risk. In addition, it requires continuous manual addition of crushed magnesium slag, resulting in a large consumption.
Design an additive device for a preheater decomposition furnace, including an annular base, mounting structure, bearing structure, feeding structure, partition structure, and additive structure. The device uses a motor to drive a rotating plate to directly add ammonia-containing magnesium slag into the decomposition furnace, mixes it with the raw material, and then calcines it into clinker. This avoids ammonia volatilization during the crushing process and reduces labor consumption.
It enables the direct addition of ammonia-containing magnesium slag into the furnace, reducing the risk of ammonia escape, improving efficiency, reducing manpower consumption, and is simple in structure and easy to use.

Description
Technical Field
[0001] This utility model relates to the field of decomposition furnaces, specifically an additive device for a preheater decomposition furnace. Background Technology
[0002] A decomposition furnace is a new type of thermal equipment that simultaneously performs fuel combustion, heat exchange, and decomposition reactions; it comes in various types and forms. The basic principle is as follows: preheated raw materials, a certain amount of fuel, and a suitable amount of hot gas are simultaneously fed into the decomposition furnace. The raw materials are in a suspended or boiling state within the furnace. Below 900°C, the fuel undergoes flameless combustion, while simultaneously completing the heat transfer and calcium carbonate decomposition process at high speed. The combustion time of the fuel and the time required for calcium carbonate decomposition are approximately 2–4 seconds. At this time, the decomposition rate of calcium carbonate in the raw materials can reach 85%–95%, and the preheated temperature of the raw materials is 800–850°C.
[0003] Due to the influence of the magnesium smelting process, magnesium slag is crushed and added. The free ammonia introduced by the magnesium slag in the batching is easily desorbed and volatilized when heated during the raw material crushing process, which can easily lead to excessive ammonia escape in the kiln tail exhaust gas, posing a great environmental risk. Moreover, it is necessary to continuously add crushed magnesium slag, which consumes a lot of manpower. Therefore, in order to solve this problem, it is very necessary to design an addition device for the preheater decomposition furnace. Utility Model Content
