Description

Technical Field

[0001] The utility model relates to the technical field of material discharging docking, in particular to an auxiliary alumina conveying docking device. Background Art

[0002] When the alumina tank truck of the electrolytic aluminum plant arrives at the unloading point, the traditional method is for workers to connect the tank truck unloading pipe with a connecting hose. Due to the large negative pressure in the conveying system, the quick connector needs to be wrapped with wire rope to ensure sealing. The entire work process is high-intensity and extremely unsafe. Against this background, a tank truck discharge port docking device has been derived. However, as the weight of the alumina powder output by the entire tank truck continues to decrease during the discharge process, the body of the tank truck slowly rises, which will generate a strong external force on the equipment. Under this effect, the internal structure of the equipment continues to loosen. The most obvious is that the inner and outer sleeves of the docking device are tilted, and the sleeve mouth is aggravated by wear and leakage, which greatly reduces the service life of the equipment. Users need to frequently replace the sleeve, and the entire disassembly and assembly process is very cumbersome. In view of the above situation, it is necessary to improve the technology to meet the use requirements.
