Description

Technical Field

[0001] This utility model relates to the field of thickener technology, and in particular to a mineral processing thickener with a defoaming device. Background Technology

[0002] A thickener is a solid-liquid separation device based on the principle of gravity sedimentation. It typically consists of a shallow cylindrical tank with a conical bottom, used to precipitate and concentrate solid particles in a suspension and separate clear water. Its core function is to achieve solid-liquid stratification through sedimentation, increase the underflow concentration, and recover clear water. It is widely applicable for treating thick industrial slurries, such as coal, metal ore dressing water, metallurgical wastewater, and chemical slurries.

[0003] Compared with existing technologies, traditional thickeners generate a large amount of foam during operation due to reagent residues, gas entrainment, and mechanical aeration. Existing defoaming methods include spray defoaming and the addition of chemical defoamers. Spray defoaming relies on a large amount of flushing water, leading to overflow turbidity and increased water treatment costs. Chemical defoamers require large amounts of reagents, which may interfere with subsequent processes and pollute the environment. These problems result in a loss of effective settling area in the thickener, frequent overflow turbidity, and seriously affect the recycling rate and underflow concentration. Therefore, we propose a mineral processing thickener with a defoaming device to solve the above problems. Utility Model Content

[0027] The defoaming mechanism includes a mounting plate 610 and a servo motor 620. The output end of the servo motor 620 is equipped with a drive rod 630, and multiple blades 640 are fixed on the outer side of the drive rod 630. The material is agitated by the drive mechanism and the stirring mechanism. During the process, the generated foam floats on the water surface. The foam on the horizontal surface is guided to the defoaming mechanism by the flow guiding mechanism. The defoaming mechanism performs a circulating defoaming operation on the foam in the material. Defoaming is performed mechanically, which does not require a large amount of rinsing water, thus reducing the cost of defoaming operation. At the same time, it avoids the pollution to the environment caused by the use of defoaming agents, prevents the loss of the thickener's settling area, ensures the utilization rate of recycled water and the underflow concentration, and improves the efficiency and quality of defoaming operation.

[0028] Specifically, the installation mechanism includes a support plate 210, which is fixed to the outside of the pool body 100 by bolts. A walking platform 220 is fixed to the top of the support plate 210, and an installation platform 230 is fixed to one side of the walking platform 220. A guardrail 231 is fixed to the top edge of the installation platform 230, and a control component 240 is fixed to the outside of the installation platform 230. With the installation mechanism, the user can walk to the installation platform 230 via the walking platform 220 and control the operation of the thickener via the control component 240.

[0029] Specifically, the agitation mechanism includes a mounting beam 410, which is fixed to the outside of the mounting sleeve 340 by bolts. A connecting bracket 420 is fixed to the bottom of the mounting beam 410, and a rake frame 430 is fixed to the bottom of the connecting bracket 420. By providing the agitation mechanism, the rotation of the mounting sleeve 340 drives the mounting beam 410 to rotate, and the mounting beam 410 drives the rake frame 430 to rotate through the connecting bracket 420. The rake frame 430 agitates the material to assist in the sedimentation process.

[0030] Specifically, the flow guiding mechanism includes a mounting slide rod 510, which is fixed to the side wall of the mounting sleeve 340. A sliding seat 520 is slidably connected to the outer side of the mounting slide rod 510. A floating box 530 is fixed to one side of the sliding seat 520. A rotating bracket 540 is fixed to the side wall of the sliding seat 520. A drive motor 550 is bolted to one side of the rotating bracket 540. A drive shaft B551 is provided at the output end of the drive motor 550. A material feeding roller 560 is fixed to the outer side of the drive shaft B551. By providing the flow guiding mechanism, during the defoaming operation, the material feeding roller 560 guides the material on the horizontal surface and directs the foam-containing material to the position of the defoaming mechanism, facilitating the defoaming mechanism to quickly defoam the material and improving the efficiency of the defoaming operation.

[0031] Working Principle: During operation, the user walks onto the mounting platform 230 via the walking platform 220 and controls the thickener's operation via the control component 240. The geared motor 320 drives the drive shaft A330 to rotate, which in turn drives the mounting sleeve 340 to rotate. The rotation of the mounting sleeve 340 then drives the mounting beam 410 to rotate. The mounting beam 410, via the connecting bracket 420, drives the rake frame 430 to rotate, agitating the material and assisting in sedimentation. During this process, the generated foam floats on the surface, and the flotation box 530 floats on the material inside the thickener, causing the feeding roller 560 to float on the material. The drive motor 550 then drives the drive shaft B551 to rotate, causing the drive shaft B551 to rotate... The rotating material feeding roller 560 guides the material on the horizontal surface and directs the foam-containing material to the defoaming mechanism. The servo motor 620 drives the drive rod 630 to rotate, which in turn drives multiple blades 640 to rotate. The blades 640 defoam the foam. The inclined blades 640 can transport the material downward and squeeze the defoamed material downward, making it easier for new material to quickly enter the defoaming area. This mechanical method eliminates the need for large amounts of rinsing water, reducing the cost of defoaming operations. At the same time, it avoids the environmental pollution caused by the use of defoaming agents and prevents the loss of the thickener's settling area. After the sedimentation operation is completed, the sediment is discharged from the drain pipe 110 through the control valve 120.
