[0002] Tailings dewatering is an important part of mining production, which involves removing water from tailings to facilitate storage, transportation and further processing of tailings. Traditional tailings dewatering equipment usually includes screening dewatering, filtration dewatering and centrifugal dewatering. However, these devices have the following problems in practical applications:

[0003] Firstly, traditional equipment can only perform single-stage dehydration, resulting in low dehydration efficiency and high moisture content in tailings. Secondly, due to the direct impact and friction of tailings, the vulnerable parts of traditional dehydration equipment wear out quickly and need to be replaced frequently, which increases maintenance costs. In addition, many traditional dehydration equipment require manual operation and have a low degree of automation, which not only increases labor intensity but also affects the stability and continuity of the dehydration process. Finally, the structural design of some dehydration equipment is not reasonable, resulting in uneven distribution of tailings during the dehydration process, affecting the dehydration effect. For this reason, we provide a multi-stage tailings vibration dehydration device. Utility Model Content
