Embodiment 1

[0021] Such as figure 2 The agitating device of the high-performance stirring tank of the present invention as shown comprises a stirring paddle, and the agitating paddle is divided into an upper paddle 3 and a bottom paddle 7, and the upper paddle 3 and the bottom paddle 7 are arranged on the top and the bottom of the stirring shaft 2 respectively. An upper steel plate cylinder 4 is arranged on the outer circle of the outer circle, and an annular baffle 5 is arranged below the upper steel plate cylinder 4. The upper steel plate cylinder 3 is connected with the side wall of the stirring tank 1 with a support plate 6, and the outer surface of the bottom paddle 7 A circle of lower steel plate cylinders 8 is arranged in a circle, and the support plates of the lower steel plate cylinders 8 are fixed on the groove bottom plate 9; 1.02-1.1 times the diameter, the height of the upper steel plate cylinder 4 is equal to the diameter of the upper layer paddle 3, the upper layer paddle ...

Embodiment 2

[0024] The lower steel plate cylinder in Example 1 is in the shape of a conical tube, in the shape of a trumpet mouth, with an opening that is small at the top and large at the bottom, and the extension line of the opening at the lower end points to the bottom corner of the groove. Others are with embodiment 1.

Abstract

The invention relates to an agitating device, in particular to an agitating device of a high-performance agitating tank. The agitating device comprises an agitating paddle, wherein the agitating paddle is divided into an upper-layer paddle and a bottom-layer paddle; the outer circle of the upper-layer paddle is provided with a circle of upper-layer steel plate cylinder; a ring baffle is arranged below the upper-layer steel plate cylinder; the upper-layer steel plate cylinder is connected with the side wall of the agitating tank through a support plate; the outer circle of the bottom-layer paddle is provided with a circle of lower-layer steel plate cylinder; and the lower-layer steel plate cylinder is fixed on a bottom plate of the tank through the support plate. The invention has the following advantages: the agitating effect is better, the flow rate is accelerated, the scouring force is greatly increased, and the agitating strength is enhanced; compared with a common paddle, the energy is saved by about 40-60%; the effect on eliminating precipitates and scabs is obvious; and a common vertical baffle is canceled, so that energy consumption is reduced, and shear on liquid flows is reduced, thereby being beneficial to the growth of crystal grains in a seed precipitation tank.

Description

technical field [0001] The invention relates to a stirring device, in particular to a stirring device of a high-performance stirring tank, which is suitable for mixing and stirring slurry in various stirring tanks in the alumina industry, especially for mixing and stirring slurry that requires high uniformity. It has high mixing uniformity, low energy consumption and low shear, and is specially designed for scab formation at the bottom of the tank, which can effectively inhibit the formation of scab formation. Background technique [0002] At present, in the production process of alumina hydrometallurgy, such as figure 1 All kinds of stirring tanks adopt central drive paddle stirring device. When working, the central shaft drives the stirring paddle to rotate, and the blade of the stirring paddle forms an included angle with the horizontal rotating surface. When the blade rotates horizontally, it produces two component forces on the liquid flow in the horizontal circumfer...
