The large-volume floating tank has the benefits that through two stages of foam pushing plates in the liquid level measuring cylinder, ore pulp entering the liquid level measuring cylinder is enabled to be free from foam and can also not fluctuate to affect the measurement accuracy; a flushing water pipe can prevent the blockage of the narrow position of the measuring cylinder due to pulp adhesion; the ore discharge valve adopts the way of coating a rubber layer outside a conical structure, so that the sealing property between the ore discharge valve and the ore discharge outlet can be ensured; the large-volume floating tank solves the problem that the large-volume floating tank cannot be accurately controlled.
Description
Technical field
the utility model relates to preparation equipment field, specifically a kind of large volume flotation cell.
Background technology
In flotation mineral process, in order to guarantee certain concentrate grade and metal recovery rate, the thickness of froth bed must be strict controlled in certain scope, also just mean and will carry out accurate Detection & Controling to mineral pulp level.Liquid level in current large-scale flotation cell is controlled and is mainly contained two kinds of modes, and the one, the aperture of manual change's drawhole ore discharge valve, to keep the height of liquid level.Because the method will judge according to artificial experience, accuracy is poor, can not carry out adjusting accurately and timely, causes liquid level unstable, cannot guarantee the thickness of froth bed.The 2nd, automatic control, liquid level detection device is mainly ultrasonic wave float-ball type and guided wave radar formula, because ore pulp is easily bonded on metal surface and guide rod, cause the mistake of the unsteady slow and radar wave of ball float to measure, in addition the ore discharge valve of existing flotation cell itself does not meet linear characteristic, make liquid fluctuating larger, the precision that impact detects.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of large volume flotation cell that is provided with liquid-level auto-control device.
The utility model solves its technical problem by the following technical solutions.
A large volume flotation cell, is provided with level gauging cylinder in described flotation cell, in described level gauging cylinder, be provided with pressure-type liquidometer; Described flotation cell below is provided with gape, and described gape is provided with ore discharge valve; Described pressure-type liquidometer connects the input of controller, the output connection valve door holder of described controller; Described valve positioner connects air lock; Described air lock connects pneumatic actuator, and the piston rod end of described pneumatic actuator connects ore discharge valve by connecting rod.
Described level gauging cylinder below is provided with strip shape gob, and described strip shape gob top is provided with I level and pushes away bubble plate.
In described level gauging cylinder, pressure-type liquidometer below is provided with II level and pushes away bubble plate.
In described level gauging cylinder, be provided with wash tub pipe.
