Beneficiation thickener with defoaming device

Abstract

The invention relates to the technical field of defoaming of thickeners, and discloses a mineral separation thickener with a defoaming device, the mineral separation thickener comprises a thickener body, the top of the thickener body is fixedly provided with a cross beam, the upper side of the cross beam is fixedly provided with a motor, and an output shaft of the motor penetrates through the cross beam and is fixedly provided with a rotating shaft; the bottom end of the rotating shaft extends into the discharging hopper and is fixedly provided with stirring blades and a bubble gathering assembly, the bubble gathering assembly comprises a water outlet pipe, an annular water outlet pipe is fixedly installed at the top of the inner wall of the thickener body, and a spray head is arranged on the side, away from the thickener body, of the water outlet pipe; and the defoaming assembly comprises a transverse rod, defoaming rods and defoaming teeth, the transverse rod is fixedly installed on the outer side of the rotating shaft and located on the upper side of the liquid level, the multiple sets of defoaming rods are fixedly installed on the bottom side of the transverse rod, and the defoaming teeth are arranged on the defoaming rods. Bubbles on the upper portion of the liquid level can be comprehensively eliminated, and the problem that bubbles still exist in a local area due to traditional spraying defoaming is solved.

Description

Technical field: [0001] The invention relates to the technical field of thickener defoaming, in particular to a thickener for ore dressing with a defoaming device. Background technique: [0002] The thickener is a kind of thickening and clarifying equipment that works continuously. It is mainly used for the dehydration of fine and tailings slurry in wet beneficiation. It uses the gravity sedimentation of particles as the working principle to realize material separation. There is a lot of foam on the surface, because solid particles will attach to the air bubbles, which will slow down the sedimentation speed of the particles and greatly reduce the efficiency of the thickener. Therefore, it is necessary to install a defoaming device on the top of the thickener to remove the air bubbles. [0003] Most of the existing thickeners use the spray method to eliminate the bubbles on the liquid surface. During the spraying process, the water droplets will break the larger bubbles, but ...

Problems solved by technology

[0002] The thickener is a kind of thickening and clarifying equipment that works continuously. It is mainly used for the dehydration of fine and tailings slurry in wet beneficiation. It uses the gravity sedimentation of particles as the working principle to realize material separation. There will be a lot of foam on the surface, because the solid particles will attach to the air bubbles, which will slow down the settling speed of the particles and greatly reduce the efficiency of the thickener. Therefore, it is necessary to install a defoaming device on the top of the thickener to remove the air bubbles.

[0003] Most of the existing thickeners use the spray method to eliminate the bubbles on the liquid surface. During the spraying process, the water droplets will break the larger bubbles, but because the small water droplets hit the liquid surface under the action of gravity, many small bubbles will be formed. This makes the bubbles still exist in the local area above the liquid surface. At the same time, there are a lot of bubbles at the edge of the existing thickener during use.
