Problems solved by technology
[0003] 1. The insertion depth of the feed material cannot be adjusted, which affects the recovery rate of the flotation column for minerals
[0004] 2. The feeder component does not support online maintenance
It can be seen that the existing feeder assembly cannot support online maintenance
In addition, the distributor and distribution pipe of the existing feeder assembly are all inside the flotation column, occupying the internal area of the flotation column, affecting the rise of the foam in the lower part of the flotation column, and ultimately affecting the recovery rate of the flotation column for minerals
[0005] 3. The pulp outlet speed of the feeder assembly cannot be adjusted
In the case of a small amount of pulp, the injection speed of the pulp is very slow, so that the pulp and foam are continuously mineralized, which affects the recovery rate of the flotation column for minerals

Embodiment Construction
[0029] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0030] Such as Figure 1 to Figure 4 As shown, the feeding device for the flotation column of the present invention includes a bracket 2 positioned outside the column body 1 and a total feed pipe 801, a buffer tank 802, more than one distribution pipe 803, and a distribution pipe 803 connected to each distribution pipe 803. The pressure slurry distributor 12 at the outlet end, the inlet end of the buffer tank 802 communicates with the main feed pipe 801, and the outlet end of the buffer tank 802 communicates with more than one distribution pipe 803 respectively; the buffer tank 802 is connected to the bracket through a lifting assembly 2, that is, through the lifting assembly, the buffer box 802 and its total feed pipe 801, distribution pipe 803 and other components can be lifted and lowered, and the insertion depth of the feed can be...

The invention discloses a flotation column and a charging device for the same. The charging device comprises a bracket, a main charging pipe, a buffer box, more than one distributing pipe and a pressure ore pulp distributor, wherein the bracket is arranged at the outer part of a column body, the pressure ore pulp distributor is connected to outlet ends of the distributing pipes, an inlet end of the buffer box is communication with the main charging pipe, an outlet end of the buffer box is communicated with the more than one distributing pipes respectively, and the buffer box is connected on the bracket through a lifting assembly. The flotation column comprises the column body and the charging device. The charging device has the advantages of simple and compact structure, low cost, stability and reliability in operation, low operation cost, convenience for maintenance, simplicity in operation, good floatation effect, wide application range and the like.
Description
technical field [0001] The invention mainly relates to the field of mineral flotation equipment, in particular to a feeding device for a flotation column and the flotation column. Background technique [0002] As the key equipment of mineral flotation, flotation column has been widely used. However, the structure of the existing flotation column has the following deficiencies: [0003] 1. The insertion depth of the feed material cannot be adjusted, which affects the recovery rate of the flotation column for minerals. [0004] 2. The feeder assembly does not support online maintenance. The feeder assembly of the existing flotation column is fixedly installed below the slurry level in the flotation column. When maintenance is required, the slurry in the flotation column needs to be released until the feeder assembly exposes the slurry level before maintenance can be performed. It can be seen that the existing feeder assembly cannot support online maintenance. In addition, ...
