Embodiment 1

[0048] like figure 1 As shown, a sintered belt cooler cooling experimental system includes a cooling chamber for cooling sintered ore, an air supply device for supplying air to the cooling chamber, the cooling chamber and the air supply device are connected, and the air supply device delivers the air flow to the cooling chamber. The sinter is cooled. There is a detection device on one side of the air supply device. The detection device is used to detect the pressure or temperature in the air supply device and the cooling room. The setting of the detection device can monitor the situation in the cooling room in real time, and the detection results are based on the actual working conditions. The detection accuracy higher. The detection device is a three-dimensional detection frame 3, which includes an X fixing rod 301 fixed on one side of the air supply device. The X fixing rod 301 is slidably connected with a horizontal sliding block 304, and the horizontal sliding block 304 i...

Embodiment 2

[0060] like Figure 4 , Figure 5 , Image 6 and Figure 7 As shown, it is basically the same as Embodiment 1, in order to ensure the cooling effect of the cooling chamber and to conduct a better observation of the sintered ore in the cooling chamber. In this implementation, the cooling chamber includes a cooling chamber frame 4 and a cooling chamber wall plate 5 arranged in the cooling chamber frame 4. Specifically, the cooling chamber frame 4 includes an inner corner plate 403, an outer corner plate 401, and an inner and outer connecting plate is passed between the inner and outer corner plates. 405 connection, and a cooling chamber wall plate 5 is arranged between the inner and outer corner plates. The inner and outer connecting plates 405 connect the inner and outer corner plates, so that a gap is formed between the inner and outer corner plates to facilitate the insertion of the cooling chamber wall plate 5 . In order to ensure the service life of the inner and outer ...

Embodiment 3

[0063] Basically the same as in Example 2, considering the research on the performance of the heated sinter, in order to save the experimental cost and realize the multi-functional utilization of the system, in this embodiment also includes a heating device for heating the sinter, the material outlet of the heating device is connected with the The material inlet of the cooling chamber is corresponding. When it is necessary to conduct research on the hot sinter, the heating device can be used to heat the sinter, and the heated sinter enters the cooling chamber for related research. The hot state experiment and the cold state experiment research can be realized at the same time, which reduces the construction cost of the experimental device. Specifically, the heating device in this implementation is a resistance furnace 1, and the resistance furnace 1 is fixedly connected with the resistance furnace base 2. The resistance furnace base 2 is used to fix and raise the height of the...

Abstract

The invention discloses a sintering belt cooler cooling experiment system and a using method thereof, and belongs to the field of belt cooler cooling. Therefore, problems of large error and low precision of an empirical numerical analysis result adopted in the cooling process of the existing belt cooler are solved. The invention provides a cooling experiment system of a sintering belt cooler, thesystem comprises a cooling chamber for cooling sinter and an air supply device for supplying air to the cooling chamber, and the cooling chamber is connected with the air supply device; a detection device is arranged on one side of the air supply device and used for detecting the pressure or temperature in the air supply device and the cooling chamber. Real-time detection is carried out through the detection device, the detection result and a numerical simulation calculation result commonly used in the cooling process of the sintering belt cooler are mutually proved, the reliability of an experiment and the calculation result in the cooling process of the sintering belt cooler is improved, and the situation that a certain difference exists between an empirical value and an actual working condition when numerical simulation calculation is adopted and the result is inaccurate is avoided. And the using method of the system is simple and convenient to operate and low in overall experimentcost.

Description

technical field [0001] The invention belongs to the technical field of belt cooler cooling, and more particularly relates to a sintered belt cooler cooling experiment system and a method for using the same. Background technique [0002] Sintering is one of the important processes before the blast furnace ore material enters the furnace for smelting. There are mainly two process methods: block sintering and pellet sintering. The raw materials required for ironmaking, such as concentrate powder, blast furnace dust, sulfuric acid slag, etc., cannot be directly added to the blast furnace. Therefore, these raw materials are generally mixed into a certain amount of fuel and solution, and they are heated to 1300~ At 1500°C, the final powder is sintered into a block. Sintering cooling is an important part of the sintering process. The cooling quality directly affects the drum strength, particle size distribution, power generation efficiency and equipment operation of sintered ore. ...
