Overflow sloping plate device of center transmission thickener

Abstract

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 plurality of sloping plates inserted into the sloping plate support in a radiation mode. The overflow grooves are connected with a tank body embedded steel plate I through the groove steel, and tooth-shaped grooves are formed in the upper portions of two sides of each overflow groove. The sloping plate support is a welding piece firmly welded on a tank body embedded steel plate II. According to the device, the length of the overflow grooves is increased, the overflow quantity is increased, the overflow and underflow concentration is obviously improved, and the concentration efficiency is improved. The productivity is improved, a driving motor is stable in current, and the raising frequency is reduced.

Description

technical field [0001] The invention relates to an overflow weir of a concentrator, more precisely relates to an overflow weir of a central drive concentrator. Background technique [0002] There are two main inspection indicators for thickeners, one is overflow water quality, and the other is underflow concentration and processing capacity. The overflow weir is an important part of the thickener, which not only controls the height of the water surface in the thickener, but also has a direct impact on the uniform water flow in the thickener and the water quality of the overflow water. The overflow weirs of large thickeners are usually of reinforced concrete structure, and the height difference of the circumference of the overflow weirs varies greatly. When the circumference of the overflow weir is uneven, the overflow water will overflow out of the pool along a certain angle of the circumference, and no overflow water will flow out from other angles. The angle with overflow...
