Embodiment Construction

[0020] The present invention will be further explained below in conjunction with the accompanying drawings.

[0021] Such as Figure 1 to Figure 5 As shown, a multi-frequency ultrasonic action flotation bubble enhanced mineralization device, its main body is a cuboid pulp tank 1, the bottom of the pulp tank 1 is provided with a supporting plate 1-1, and the supporting plate 1-1 is provided with There is a sealing rubber plate 1-2, the material of the sealing rubber plate 1-2 is styrene-butadiene rubber, and the supporting plate 1-1 and the bottom edge 1-3 of the pulp tank body 1 are fixed and sealed by bolts 1-4. The geometric center of the support plate 1-1 is provided with an array of through holes with a diameter less than or equal to 1mm, which are used to feed flotation air bubbles, so that the air bubbles escaping from the needle of the air bubble generator can be evenly distributed.

[0022] On the opposite sides of the slurry tank body 1, three sets of ultrasonic exci...

Abstract

The invention discloses a multi-frequency ultrasonic action flotation bubble strengthening mineralization device, which includes a pulp tank body, a through hole for passing through the flotation bubbles is located at the bottom of the pulp tank body, on the opposite side of the pulp tank body, from A plurality of ultrasonic excitation mechanisms are arranged at relative intervals from top to bottom. The ultrasonic excitation diffusion plates of the two ultrasonic excitation mechanisms at the same horizontal height are arranged facing each other, and the ultrasonic excitation frequencies are the same. From the bottom of the slurry tank upwards, the ultrasonic excitation frequency of the ultrasonic excitation mechanism increases sequentially, and the distance between the ultrasonic excitation diffusion plates that are arranged facing each other decreases sequentially. The invention adopts a multi-frequency ultrasonic excitation mechanism to perform multi-level ultrasonic treatment on the flotation bubbles, which can realize the effect of ultrasonic effects of different frequencies on the flotation bubbles during the rising process as the pressure changes, which is conducive to strengthening the flotation bubbles Collision‑adhesion effects with mineral particles in the slurry.

Description

technical field [0001] The invention relates to a column flotation mineralization device. Background technique [0002] Column flotation technology is currently the main advanced separation technology for mineral extraction and is widely used in the field of mineral processing. The key to column flotation technology is that the mineral particles in the slurry can effectively adhere to the flotation bubbles to complete the mineralization process. Therefore, intensifying the mineralization process is an extremely important method to improve the mineral separation characteristics in the optimization of the column flotation technology route, which can effectively improve the utilization rate of mineral resources, and the method of improving the mineral separation characteristics through the mineralization process has received much attention. attention at home and abroad. In the existing column flotation technology, a large amount of flotation chemical reagents will remain in th...
