Description

Flotation column distributor

Technical Field

The utility model relates to a flotation column distributor for mineral separation, and belongs to the technical field of mineral separation machinery.

Background

The main function of the flotation column distributor for mineral separation is to uniformly distribute and throw the ore pulp from the concentration distribution box as raw material into the interior of the concentration flotation column for flotation. The existing flotation column distributor is generally of a total division type, ore pulp serving as raw materials flows into an ore feeding branch pipe through a main ore feeding pipe, and the ore pulp is distributed to all directions of a fine flotation column through the ore feeding branch pipe. The existing flotation column distributor mainly has the following two defects: firstly, it is difficult to uniformly distribute the ore pulp on the premise of uniform concentration. Secondly, the problem of short ore pulp mineralization time commonly exists in the ore pulp distribution process, and the ore pulp is in contact with air and is insufficiently mixed, so that the flotation efficiency is reduced. For example, chinese utility model publication No. CN202933789U discloses a "flotation column feed system" comprising a feed pipe and a plurality of slurry outflow pipes; the ore feeding pipe is transversely inserted into the column body of the flotation column and is fixed with the column body through a flange; the ore pulp outflow pipes are arranged on the pipe wall of the ore feeding pipe. The ore pulp flows in the closed pipeline and is split, and the ore pulp is in contact with air and is insufficiently mixed.

Disclosure of Invention

The utility model aims to solve the technical problems of providing a flotation column distributor, which firstly, uniformly distributes ore pulp on the premise of uniform concentration; and secondly, the ore pulp can be fully contacted with air in the process of being distributed.

The technical scheme of the utility model is as follows:

the flotation column distributor comprises a cylinder body with ports at the upper end and the lower end, wherein an upper flange is arranged at the upper port, a lower flange is arranged at the lower port, and a bottom plate for closing the lower port is connected with the lower flange through a connecting bolt; the side wall of the cylinder is fixedly connected with a plurality of distributing pipes communicated with the inner cavity of the cylinder; the distribution pipes are circumferentially and uniformly distributed around the cylinder body and have equal heights.

Preferably, the upper end of the cylinder is provided with a feeding pipe with radial dimension smaller than that of the cylinder; the upper flange is arranged at the upper port of the feeding pipe.

The utility model has the positive effects that:

the first, the utility model give the ore pipe and float the pillar distributor flange to communicate fixedly through the bolt, the bottom of the cylinder forms a bottom sealed distributor with bottom plate through the fixing bolt. The ore pulp from the ore feeding pipeline enters the bottom of the distributor from the upper flange of the distributor and the cylinder body, and overflows into the distributing pipe after the ore pulp fills the bottom. The flotation column distributor does not need external power, can realize the equal output of each stock pulp flow and ensure the uniform and consistent concentration of each stock pulp, ensures the working stability of the inside of the entering flotation column, can improve the recovery rate of the flotation column, is beneficial to capturing the bubble minerals, fully exerts the equipment efficiency, improves the equipment operation technical index and meets the production requirement.

Secondly, by adopting the utility model, the ore pulp is more fully stirred, contacted with air and mixed more fully and thoroughly after falling and impacting with the distributor, rising and overflowing the liquid level before entering the distributing pipe. And the subsequent flotation efficiency is improved more favorably.

Detailed Description

The utility model is further described below with reference to the drawings and examples.

As shown in fig. 1 and 2, an embodiment of the flotation column distributor according to the utility model comprises a cylindrical body 3 provided with ports at both the upper and lower ends, wherein the upper port is provided with an upper flange 1 and the lower port is provided with a lower flange 6. The lower flange 6 is connected with a bottom plate 5 for closing the lower port through a connecting bolt 7.

A plurality of (six in this embodiment) distributing pipes 4 communicated with the inner cavity of the cylinder 3 are fixedly connected to the side wall of the cylinder 3. The distribution pipes 4 are circumferentially distributed around the outer side of the cylinder body 3 and have the same height. Each distribution pipe 4 is provided with an ore discharge opening which is inclined downwards.

Further, in order to facilitate the fitting and the abutting joint with the ore feeding pipeline, the upper end of the cylinder body 3 is provided with a feeding pipe 2 with a radial dimension smaller than that of the cylinder body 3. The upper port of the feed pipe 2 is provided with an upper flange 1.

The bottom plate 5 and the lower flange 6 are detachably connected through connecting bolts 7. After the distributor is used for a period of time, the bottom plate 5 is convenient to detach, and cleaning and maintenance are carried out on the inner wall of the cylinder 3 and the root of the distributing pipe 4.

In use, the feeder duct is connected to the dispenser of this embodiment via the upper flange 1. The ore pulp from the ore feeding pipeline sequentially enters the bottom of the cylinder body 3 through the upper flange 1 and the feeding pipe 2. After filling the bottom, the slurry overflows into a distribution pipe 4.

The amount of pulp flowing into the flotation column distributor is controlled by an electrically operated valve on the beneficiation box, the pulp enters the bottom of the cylinder 3 serving as the distributor box, and the liquid level in the distributor box is gradually increased along with the entering of the pulp. When the liquid level reaches the root of the distributing pipe 4, the ore pulp overflows into the flotation column through the distributing pipe 4. Because the height of each distributing pipe 4 is consistent, the pressure of each distributing pipe 4 is equal under the condition of a certain liquid level of the distributor, thereby realizing the equal output of each strand of ore pulp flow, ensuring the uniform and consistent concentration of each strand of ore pulp and meeting the production requirement.
