Description

Technical Field

[0001] The utility model relates to the technical field of sintering machine blowing equipment, in particular to a sintering machine material surface blowing device. Background Art

[0002] To reduce the coke ratio and smelting costs of blast furnace ironmaking, blast furnaces often require high strength and high reducibility for sintered ore. During the sintering process, sintered ore is generally required to have high strength, high yield, low return rate, and low fuel consumption. High-strength and high-reducibility sintered ore consumes less coke during blast furnace smelting, thereby reducing CO2 emissions. To improve the overall performance of sintered ore, gas fuel injection technology is currently widely used in sintering operations. This technology injects gas fuel (coal gas) onto the sintering material on the sintering trolley through an injection device, causing it to burn and provide heat within the sintering material layer, thereby reducing the amount of solid carbon used in sintering and CO2 emissions. However, the injected gas contains certain impurities such as tar and dust, which are viscous. Due to the small injection holes, the holes can easily become clogged. Subsequent cleaning requires workers to use a cleaning brush to clean each injection hole one by one, which is very tedious and significantly increases the workload. Utility Model Content

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0015] like Figure 1-2 As shown, the sintering machine material surface blowing device described in this embodiment includes a sintering trolley 1 and a blowing hood 2 arranged outside the sintering trolley 1, a blowing pipeline is provided on the outside of the blowing hood 2, and the blowing pipeline extends into the blowing hood 2. A diverter box 3 is provided at one end of the blowing pipeline located in the blowing hood 2, and the diverter box 3 is located above the sintering trolley 1. A plurality of detachable blowing heads 4 are provided at the bottom of the diverter box 3, and a multi-faceted hollow ball 5 is placed in the blowing head 4.

[0016] The blowing head 4 is a cylindrical structure with an open upper end. The open end of the blowing head 4 is connected to the air hole at the bottom of the diversion box 3. The lower end of the blowing head 4 is uniformly provided with blowing holes 4a along the circumference, and the multi-faceted hollow ball 5 is placed in the cavity inside the blowing head 4.

[0017] The spray holes 4 a located on the side wall of the spray head 4 are arranged tilted downward. The tilted spray holes 4 a can effectively prevent the dust in the spray cover 2 from entering the interior of the spray head 4 .

[0018] An internal thread is provided in the air hole at the bottom of the diverter box 3 , and an external thread is provided on the side wall of the upper end of the blowing head 4 , and the blowing head 4 is threadedly connected to the air hole.

[0019] Preferably, the multifaceted hollow sphere 5 is made of metal.

[0020] The spray pipeline includes a spray main pipe 6 located outside the spray hood 2, and a number of spray branch pipes 7 extending into the spray hood 2 are evenly distributed on the spray main pipe 6. A diversion box 3 is provided at one end of each spray branch pipe 7 located inside the spray hood 2, and the spray branch pipe 7 is connected to the top of the diversion box 3.

[0021] The working principle of the present utility model is as follows: the injection main pipe 6 is connected to the gas tank, and the gas fuel enters each injection branch pipe 7 along the injection main pipe 6 and transports the gas fuel to the diversion box 3. The gas fuel will first pass through the multifaceted hollow ball 5. Since the multifaceted hollow ball is a spherical structure with a hollow surface, the contact surface of the multifaceted hollow ball 5 will absorb impurities in the gas fuel, and the gas fuel will flow through the holes on the multifaceted hollow ball 5 and finally be blown out at the injection hole 4a on the injection head 4. The blown gas fuel is sprayed onto the sintered ore on the sintering trolley 1. When the injection head 4 needs to be cleaned, it is only necessary to unscrew the injection head 4 and take out the multifaceted hollow ball 5 inside it for cleaning. The multifaceted hollow ball 5 can effectively block impurities in the gas fuel and prevent impurities from clogging the air holes on the injection head 4.
