Overflow sloping plate device of center transmission thickener

The invention discloses an overflow sloping plate device of a center transmission thickener. The device solves the problem that the circumference altitude difference of an overflow weir of the existing large thickening tank is large. The device is characterized by comprising a concrete tank body, a water outlet, an ore feeding tube, a plurality of groups of overflow grooves, groove steel, a plurality of groups of sloping plate devices and a sloping plate support. The ore feeding tube is fixedly welded with the sloping plate support, the upper portion of the ore feeding tube is higher than the overflow grooves, and the lower portion of the ore feeding tube is lower than the sloping plates. The plurality of groups of overflow grooves are evenly distributed along the ore feeding tube, one end of each overflow groove is connected with the ore feeding tube, and the other end of the overflow groove is connected with a reserved water outlet of the concrete tank body. Each group of sloping plate devices comprise a pl
