Description

Technical Field

[0001] The present application relates to the technical field of sintering machines, and in particular to a device for reducing the sintering fuel consumption of a sintering machine trolley. Background Art

[0002] Sintering machine is a kind of equipment used for large-scale smelting and sintering operations, mainly used for the sintering treatment of iron ore powder. Its working principle is to mix, pelletize and granulate the raw materials required for sintering in a mixer, and then transport them to the shuttle distributor through a belt conveyor. Then the raw materials pass through the front and back movement of the shuttle distributor and evenly fall into the head hopper of the sintering machine. The opening size of the movable auxiliary door is adjusted according to the running speed of the sintering machine. With the rotation of the round roller distributor, the material goes down to the nine-roller distributor, and then falls evenly onto the loosener and the trolley with the rotation of the nine rollers. After being leveled by the scraper device, it enters the ignition furnace of the sintering machine for ignition and sintering. The fuel consumption of the sintering machine trolley is high when it is working, and the production efficiency is low. How to effectively reduce the fuel consumption of the sintering machine when it is working has become one of the important research directions in the smelting industry.

[0003] In the relevant technology, there are two main ways to reduce the fuel consumption of the sintering machine car: combustion control and fuel improvement. Combustion control is achieved through reasonable control means, such as adjusting the combustion temperature, oxygen supply and fuel ratio, etc., to reduce the fuel consumption; fuel improvement is achieved by changing the properties and ratio of the fuel, such as the particle size, volatile matter content, ash content, etc. of the fuel, to reduce the fuel consumption.

[0004] However, both of the above two approaches have corresponding defects. The former has high control complexity. Combustion control involves the adjustment and coordination of multiple parameters, and requires advanced automatic control systems and precise sensors, which increases equipment costs and maintenance difficulties. At the same time, stability is difficult to guarantee. During the combustion process, changes in factors such as raw material properties and combustion environment will affect fuel consumption, which requires real-time monitoring and adjustment. In addition, the smoke, gas and other combustion products produced during the combustion process need to be effectively treated and purified, which increases the process and equipment investment for subsequent treatment. During the implementation of the latter, there is a problem of insufficient supply of improved fuel, and additional investment in fuel pretreatment is required, which increases production costs and risks. At the same time, the combustion characteristics of the improved fuel may be unstable due to factors such as raw material sources and seasonal changes, resulting in fluctuations and uncontrollability of combustion. Different fuels differ in combustion characteristics, chemical composition, etc., and the scope of application of fuel improvement is limited, which may not meet all process requirements. Both of the above two approaches have corresponding defects and shortcomings. In the specific real-time process, it is also difficult to ensure the reduction of fuel consumption. Therefore, the present application proposes a device for reducing the sintering fuel consumption of a sintering machine trolley to solve the problem of excessive fuel consumption of a sintering machine.
