[0006] In order to maintain the shape of the felt layer and fix its position, as a preferred foam tank plug for mineral processing and flotation of the utility model, the felt layer is located between the upper arc plate and the lower arc plate, and the bolts are connected through the upper arc plate, the felt layer and the lower arc plate.

[0007] In order to make the felt layer contact with the pipeline orifice and further achieve a good sealing effect, as a preferred foam tank plug for mineral processing and flotation of the utility model, the widths of the upper arc plate and the felt layer are both greater than the diameter of the pipeline orifice, and the width of the lower arc plate is less than the diameter of the pipeline orifice.

[0008] In order to facilitate the staff to lift the plug to change the opening and closing state of the pipeline, as a preferred foam tank plug for mineral processing and flotation of the utility model, a handle is fixedly provided on the upper end of the lifting rod.

[0009] In order to limit the position of the lifting rod, as a preferred foam tank plug for mineral processing and flotation of the utility model, a limiting piece is fixedly provided in the middle of the lifting rod, and the limiting piece is located above the upper arc plate.

[0010] The beneficial effects of the utility model are as follows: the upper and lower arc plates clamp and fix the felt layer by bolts, and when in use, the arc plug is placed above the pipe orifice, the felt layer is in full contact with the edge of the pipe orifice, and relies on the gravity provided by the counterweight block below to compact the felt and the pipe orifice, and the minerals in the foam are attached to the felt through the filtering effect of the felt layer to achieve a sealing effect, while tightly blocking the foam tank pipe orifice, the plug can also be quickly and effectively switched between closed and open states.
