AI Technical Summary
The presence of numerous air bubbles in the concentrate slurry after flotation leads to low settling efficiency of the thickener, accelerated equipment wear and tear, equipment failure, and impacts product quality and production costs.
Design a degassing tank for a thickener, comprising a tank body, a flow disturbance device, and a flow guide plate. The flow disturbance device breaks up bubbles, and the flow guide plate guides the slurry flow, extending the bubble rise time and achieving preliminary gas-solid separation.
Reduce the amount of air bubbles entering the thickener, improve sedimentation efficiency, avoid overflow turbidity and insufficient underflow concentration, and reduce equipment wear and maintenance costs.

Abstract
Claims
1. A deaeration tank of a thickener, characterized by, It includes a tank, a flow-dispersing device disposed in the tank, and at least one guide plate. A feed pipe is disposed above the tank, and the outlet of the feed pipe is located above the tank. A discharge port is opened on the tank, and the discharge port is connected to a discharge pipe.
2. A deaeration tank for a thickener as claimed in claim 1, wherein, The trough is a rectangular structure, and there are at least two guide plates. The guide plates are arranged alternately along the length of the trough, with the guide plate closer to the feed pipe being higher than the guide plate farther from the feed pipe. The turbulence device is located directly below the outlet of the feed pipe.
3. A deaeration tank for a thickener as claimed in claim 2, wherein, A gap exists between the bottom of one of the guide plates near the feed pipe and the bottom wall of the tank, so that the slurry flows in an S-shaped trajectory within the tank.
4. A deaeration tank for a thickener according to claim 2 or 3, characterised in that, The side of the guide plate is connected to the inner wall of the tank via a height adjustment assembly.
5. A deaeration tank for a thickener as defined in claim 1, characterized in that The turbulence-disrupting device includes a rotating shaft, a turbulence-disrupting propeller mounted on the rotating shaft, and a motor for driving the rotating shaft to rotate. The rotating shaft is rotatably connected to the bottom of the tank, and the motor is installed at the bottom of the tank.
6. A deaeration tank for a thickener according to claim 5, wherein Several of the aforementioned turbulence propellers are arranged alternately along the axial direction of the rotating shaft.
7. A deaeration tank for a thickener as claimed in claim 5 wherein, The side wall of the tank is also provided with a fixed baffle plate, which is perpendicular to the side wall of the tank and is located outside the rotation radius of the baffle propeller.
8. A deaeration tank for a thickener as defined in claim 1, characterized in that A flow meter and a flow control valve are connected to the feed pipe. The flow control valve is used to adjust the flow rate of the slurry entering the tank through the feed pipe.
9. A deaeration tank for a thickener as claimed in claim 8, wherein, The number of feed pipes is three, and the three feed pipes are respectively connected to the flotation concentrate slurry pipe, the thickener underflow pipe and the filter overflow pipe.
10. A deaeration tank for a thickener as claimed in claim 1, wherein, The tank is equipped with level gauges on both the upper and lower sides of its sidewalls.
