Description

Technical Field

[0001] The utility model relates to the technical field of thick material layer sintering, in particular to a novel trapezoidal material distribution device with adjustable material distribution thickness for a sintering machine. Background Art

[0002] With the development of sintering technology, thick bed sintering technology has become a key technology to effectively improve the quality of sintered ore and reduce the cost of sintering production. The application of thick bed sintering process mainly benefits from the in-depth understanding of the "sintering bed automatic heat storage principle" and "low temperature sintering theory". The thick bed low temperature sintering process has excellent sintering effect.

[0003] In the process of pursuing thick material layers, it should be noted that the thickness of the material layer should match the particle size of the raw materials and process parameters. The thickness of the material layer should not be increased blindly. Under cost pressure, most sintering machines are increasing the use of economic defective materials, resulting in increased production instability. It is necessary to stabilize the production process by adjusting the material thickness. The trapezoidal material distribution devices currently used are all fixed material thickness and do not have the ability to adjust the material thickness in real time. For this reason, we propose a new type of trapezoidal material distribution device with adjustable material thickness for sintering machines to solve the above problems. Utility Model Content

[0004] The utility model aims to provide a novel trapezoidal material distribution device with adjustable material distribution thickness for a sintering machine, so as to solve the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] In a further embodiment, the upper surface of the wing-shaped flat material plate is connected to an electric push rod via a pin shaft, the top end of the electric push rod is hinged to a first U-shaped plate via a pin shaft, and the bottom end of the first U-shaped plate is connected to the upper surfaces of the two baffle plates.

[0008] In a further embodiment, the scraper assembly includes a second U-shaped plate fixedly connected to the upper surfaces of the two baffle plates, the upper surface of the second U-shaped plate is provided with a threaded hole, the inner wall of the threaded hole is threadedly connected to a threaded rod, and the bottom end of the threaded rod is rotatably connected to a push plate.

[0009] In a further embodiment, two stabilizing grooves are provided on the inner side surface of the second U-shaped plate, and the inner wall of each stabilizing groove is slidably connected with a stabilizing block, and the ends of the two stabilizing blocks close to each other are respectively connected to the front and back sides of the push plate.

[0010] In a further embodiment, the top end of the threaded rod is fixedly connected to a handle, and the outer surface of the handle is covered with an anti-slip cover.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] Through the transformation of the material distribution device, this device can greatly improve the material distribution thickness of the sintering machine and increase the sintering uniformity under the premise of low investment cost by implementing "trapezoidal material distribution", so as to achieve the purpose of improving the quality of sintered ore and reducing sintering cost. At the same time, an adjustable material distribution thickness device is added. When an abnormal situation occurs and the material distribution thickness needs to be reduced, the thickness can be reduced immediately to avoid the situation where the surface unevenness caused by the trapezoidal material distribution cannot be scraped to the material surface due to the reduction of the material distribution thickness, which causes the increase of the return ore.
