Abstract

The invention discloses a variable-frequency aeration device for rare earth tail water treatment, which belongs to the technical field of variable-frequency aeration and comprises an aeration tank, apower mechanism, a stirring mechanism and a variable-frequency mechanism, the top of the aeration tank is covered with an upper cover, the power mechanism and the variable-frequency mechanism are connected and mounted on the top surface of the upper cover, and the stirring mechanism is distributed inside the aeration tank. And one end of the power mechanism sleeves the stirring mechanism. According to the variable-frequency aeration device for rare earth tail water treatment, a main pipe of an air pump sleeves a rotating shaft, air extracted by the air pump is fed into the rotating shaft through the main pipe, a stirring shaft rotates around the rotating shaft, and in the rotating process, the connecting position of the two parts is connected through a sealing ring, so that the problem ofpoor sealing performance cannot occur; gas conveyed by the air pump can completely enter the rotating shaft, the main pipe is communicated with an inner cavity of the stirring shaft, an auxiliary pressurizing pipe conveys the gas to the stirring shaft through air holes, finally an aeration disc aerates the gas, the flow speed of the gas conveyed into the stirring mechanism is changed, and frequency conversion is achieved.

Description

technical field [0001] The invention relates to the technical field of frequency conversion aeration, in particular to a frequency conversion aeration device for rare earth tail water treatment. Background technique [0002] The source of rare earth mine tail water is two aspects: on the one hand, it comes from the tail water after clear water washing of rare earth mines. Clean water cleaning is mainly aimed at the fact that the soil in the in-situ leaching stope still contains ammonia nitrogen, which has potential environmental risks. The mine is required to fill in clean water for cleaning, and then use the liquid collection system in the in-situ leaching stope to collect tail water; on the other hand , derived from the seepage fluid produced by leaching under natural rainfall conditions after the mining of rare earth mines. The tail water of rare earth mines contains ammonia nitrogen, sulfate and rare earth ions with low concentration. The rare earth ions in the tail wat...
