Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of ore dressing equipment, in particular to a ladder-shaped flotation cell tank bottom. BACKGROUND

[0002] The tank bottom of the flotation cell is the main load-bearing component of the flotation cell, and the self-weight of the equipment and the weight of the treated ore pulp are all applied to the tank bottom of the flotation cell. In recent years, the flotation cell has developed rapidly in size, and the load to be borne by the tank bottom of the flotation cell has increased sharply.

[0003] However, the tank bottom of the existing flotation cell still has some drawbacks. The tank bottom of the traditional flotation cell is flat, and the bottom support is a grid support composed of rectangular steel plates. In order to adapt to the large-scale development of the flotation cell, the grid support is increased in height and density to improve its carrying capacity. The increase in height of the grid can effectively improve the strength of the tank bottom of the flotation cell, but it is limited by the transportation height and the installation height, and the increase in density of the grid has no economic effect on improving its carrying capacity. Therefore, we propose a ladder-shaped flotation cell tank bottom. SUMMARY

[0004] In order to overcome the shortcomings of the prior art, the present application provides a ladder-shaped flotation cell tank bottom, which changes the structure of the traditional flotation cell tank bottom and provides multiple rectangular plates along the direction of the ore pulp flow of the flotation cell.
