Description

Technical Field

[0001] This utility model relates to the field of flotation cell technology, and in particular to flotation cells. Background Technology

[0002] A flotation cell is a container used in flotation equipment to carry out the flotation process. Flotation machines are widely used in mineral flotation and pulp and paper flotation. In mineral flotation, when the flotation cell is working, as the impeller rotates, the slurry in the cell is drawn from the sides through the bottom of the cell to the space between the impeller blades. Simultaneously, low-pressure air supplied by a blower enters the cell through the hollow shaft and the air distributor of the impeller. After the slurry and air are thoroughly mixed between the blades, they are pushed upwards from the upper periphery of the impeller and then, after being stabilized and directed by the stator, enter the entire cell. Bubbles rise to the foam stabilization zone, undergo an enrichment process, and then overflow from the overflow weir into the foam tank. Some slurry flows to the lower part of the impeller, where it is agitated again by the impeller and remixed to form mineralized bubbles. The remaining slurry flows to the next cell until it finally becomes tailings.

[0003] Flotation cells and flotation columns are two core pieces of equipment for mineral separation. Flotation cells achieve pulp aeration and bubble dispersion through mechanical stirring, which is suitable for separating coarse minerals. However, they have the following problems: poor bubble uniformity: a single air source or fixed nozzles result in a wide distribution of bubble size in the pulp, and large bubbles reduce mineralization efficiency; lag in control: manual adjustment of the air intake cannot respond in real time to changes in ore properties; energy waste: constant air pressure supply leads to redundant energy consumption when processing low-grade ores; complex maintenance: traditional aeration equipment is prone to clogging and requires frequent shutdowns for cleaning. Flotation columns achieve efficient recovery of fine minerals through countercurrent mineralization, but have low processing capacity and high energy consumption. Utility Model Content

[0004] To address the problems of crude control and poor responsiveness in traditional aeration devices, this invention provides a flotation cell, the technical solution of which is as follows:

[0005] A flotation cell includes a cell body and an aeration structure. A through slot and a slot are respectively provided on the left and right sides inside the cell body. A bottom baffle and a top baffle are respectively provided at the bottom and top of the through slot.

[0006] The inflation structure includes a connecting pipe, a movable cover, an inflation pipe, and an inflation pump. The connecting pipe is located at the bottom of the tank, the movable cover is located at the bottom of the outer surface of the connecting pipe, the inflation pipe is located at the bottom of the movable cover, and the inflation pump is located at the end of the inflation pipe away from the movable cover.

[0007] The change in the length of the aeration pipe, the limitation of the porous medium, and the impeller stirring make the bubbles fine and controllable, which improves the flotation recovery rate of both oxide and sulfide ores. The lower aeration allows large mineral particles to come into contact with the bubbles, improving their floatability.

[0008] Preferably, a fixing hole is provided on the right side of the outer surface of the groove, and the fixing hole extends into the groove.

[0009] Preferably, the bottom of the through groove has an opening that communicates with the connecting pipe, and the inside of the opening is filled with a screen.

[0010] Preferably, the bottom of the outer surface of the connecting pipe and the inner side of the movable cover are provided with interlocking threads, and a porous medium is provided between the movable cover and the connecting pipe.

[0011] Preferably, the inflation tube is 45mm long and is connected to the interior of the through groove through a movable cover, a connecting tube, and an opening.

[0012] Preferably, the bottom baffle is fixedly installed, and a space is reserved between the bottom baffle and the bottom of the through groove and the bottom of the top baffle.

[0013] Preferably, the top baffle is movable, and the front and back sides of the inner wall of the through groove are provided with mounting holes that are adapted to the size of the top baffle.

[0014] Preferably, a lifting block is provided at the top of the top baffle.

[0015] By changing the length of the air inlet tube extending into the movable cover, the airflow at the bottom is altered, thereby changing the size of the bubbles. The combination of porous media, air inlet tube, movable cover, and air pump simulates the effect of a flotation column foaming machine, achieving micro-bubbles during bottom air inlet and optimizing the flotation effect. Beneficial effects

[0016] The beneficial effects of adopting the technical solution of this utility model are as follows:

[0017] 1. In this flotation cell, the change in the length of the air inlet pipe, the restriction of the porous medium, and the impeller stirring make the bubbles fine and controllable, which improves the flotation recovery rate of both oxide and sulfide ores. The lower air inlet allows large mineral particles to come into contact with the bubbles, improving their floatability.

[0018] 2. This flotation cell changes the size of the bubbles by altering the length of the airflow at the bottom through the extension of the air inlet pipe into the movable cover. The combination of porous media, air inlet pipe, movable cover, and air pump simulates the effect of a flotation column foaming machine, thereby achieving micro-bubbles during lower air inlet and optimizing the flotation effect.
