Description

Technical Field

[0001] The utility model belongs to the technical field of ore dressing and mining equipment, and in particular relates to an air volume control device for an air-filled flotation machine. Background Art

[0002] Flotation machine is a kind of mineral processing equipment that mechanically stirs the slurry to make the useful minerals in the slurry rise with the bubbles. The flotation machine has the characteristics of low energy consumption, small footprint, easy maintenance and high mineral processing efficiency. At present, most mineral processing companies use aerated flotation machines for roughing and fine operations in the flotation process. However, since the aeration of the flotation machine is entirely adjusted manually, the gas volume will fluctuate, thereby affecting the thickness of the foam layer and the mineral processing effect, which not only wastes labor costs but also has low work efficiency. Utility Model Content

[0003] In view of the shortcomings of the prior art, the purpose of the utility model is to design an air volume control device for an aerated flotation machine to solve the problem mentioned in the background technology that the flotation machine inflation is manually adjusted, resulting in fluctuating air volume, affecting the thickness of the foam layer and thus affecting the mineral processing effect.

[0004] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an air volume control device for an inflatable flotation machine, comprising a main body, a box, an air inlet pipe, a control valve, a bubble detector and a PLC controller, wherein the main body is arranged in the box, an air inlet pipe is arranged on the upper part of the main body, a control valve is arranged on the air inlet pipe, the air inlet pipe after passing through the control valve is immersed in the box, a bubble detector is arranged in the box, the bubble detector is connected to the PLC controller via a connecting line, and the PLC controller is also connected to the control valve via a connecting line.

[0005] There are multiple main bodies, each of which is provided with a corresponding box and an air inlet pipe, each air inlet pipe is provided with a control valve, each box is provided with a bubble detector, and the control valve and the bubble detector are connected to a PLC controller together.

[0006] The control valve is connected to the PLC controller in parallel; the bubble detector is connected to the PLC controller in parallel.

[0007] The beneficial effects of the utility model are as follows: the device has a simple structure, greatly reduces the change of flotation effect caused by manual adjustment, which leads to the phenomenon of deterioration of flotation effect, and improves the working efficiency of the flotation machine; at the same time, the device is automatically controlled and does not require human operation, which saves labor costs and indirectly increases benefits for the enterprise.
