Description

Technical Field

[0001] The invention relates to the technical field of sedimentation tanks, in particular to a multi-stage sedimentation tank for chalcopyrite beneficiation. Background Art

[0002] Sedimentation tank is a kind of structure that uses sedimentation to remove suspended matter in water. It is a device for purifying water. It uses the natural sedimentation or coagulation sedimentation of water to remove suspended matter in water. Sedimentation tanks are divided into horizontal sedimentation tanks and vertical sedimentation tanks according to the direction of water flow. The sedimentation effect is determined by the flow rate of water in the sedimentation tank and the residence time of water in the tank.

[0003] During the sedimentation process in the sedimentation tank, some scrapers are used to collect the sludge deposited at the bottom of the tank, and then the sludge is pumped out through the sewage pumping device. This treatment method has certain defects. When the scraper rotates in the water, it will inevitably stir the sludge and water deposited at the bottom, which is not conducive to the deposition of sludge and slows down the deposition speed of sludge. At the same time, when the sludge pump is sucking sludge, there is no equipment to isolate the sludge and water, which leads to a large amount of water being sucked away during the sewage suction process, which increases the sewage discharge time, that is, increases the sedimentation cost.

[0016] Beneficial effects of the present invention:

[0017] (1) The multi-stage sedimentation tank for chalcopyrite beneficiation described in the present invention adopts an isolation and drainage mechanism. When drainage is required, the telescopic rod is started, and one end of the telescopic rod is extended to drive the connecting block to move downward, thereby driving the movable plate to move downward, thereby driving the collecting pipe, the movable plate, the movable groove, the first spring and the first protrusion to move downward synchronously. Since the upper part of the track plate is a slope structure, the first protrusion moves to the left and compresses the first spring when it moves downward along the surface of the track plate, and at the same time drives the movable plate and the movable groove to move to the left, the movable groove and the collecting pipe gradually disengage, and the movable plate and the collecting pipe gradually cooperate and seal. When the first protrusion moves to the vertical position of the track plate, the movable plate and the collecting pipe are completely sealed. At this time, the water and mud under the movable plate are squeezed, and the lower drainage part is isolated from the upper sedimentation part, ensuring that the drainage work will not affect the sedimentation of the upper sewage, thereby improving the sedimentation efficiency.

[0018] (2) The multi-stage sedimentation tank for chalcopyrite beneficiation described in the present invention adopts an extrusion mechanism. The water and sludge under the movable plate are squeezed, and the water flows out of the filter plate into the return pipe and flows back into the sedimentation shell. When the first protrusion moves and contacts and squeezes the second protrusion, the second protrusion is squeezed and moved to the right, thereby driving the first connecting rod, the second connecting rod and the third connecting rod to move to the right, and squeezing the second spring at the same time. The third connecting rod moves to the right and drives the sealing plate to move to the right. The sealing plate and the sludge bin gradually break away from the sealing fit. The sealing plate moves to the right and squeezes the third spring. The third spring squeezes the pressure switch. When the first protrusion moves and contacts the top of the second protrusion, the telescopic rod stops extending. At this time, the pressure received by the pressure switch reaches the switch opening pressure, and the external sewage suction device starts to work to suck away the sludge from the sewage suction port. Before starting the sewage discharge device, most of the water is squeezed out first, which reduces the workload of the sewage discharge device, reduces the working time of the sewage discharge device, and reduces the sedimentation cost.

Mud and flocs settle and fall, and fall into the collection port 515 and the sludge bin 516 through the trapezoidal groove 53, as shown in FIG.

Since the upper part of the track plate 59 is a slope structure, the first protrusion 58 moves to the left along the surface of the track plate 59 and compresses the first spring 57, while driving the movable plate 55 and the movable groove 56 to move to the left. The movable groove 56 gradually disengages from the collecting pipe 54, and the movable plate 55 and the collecting pipe 54 gradually cooperate and seal. When the first protrusion 58 moves to the vertical position of the track plate 59, the movable plate 55 and the collecting pipe 54 are completely cooperated and sealed. At this time, the water and mud under the movable plate 52 are squeezed, and the water flows out from the filter plate 518 into the reflux pipe 519 and flows back into the sedimentation Inside the housing 51, when the first protrusion 58 moves and contacts and squeezes the second protrusion 512, the second protrusion 512 is squeezed and moved to the right, thereby driving the first connecting rod 510, the second connecting rod 513 and the third connecting rod 514 to move to the right, and squeezing the second spring 511 at the same time.

After the sewage discharge is completed, the movable plate 52 moves upward, thereby driving the collecting pipe 54, the movable plate 55, the movable groove 56, the first spring 57 and the first protrusion 58 to move upward synchronously, the first protrusion 58 moves and gradually disengages from the extrusion of the second protrusion 512, and the second protrusion 512 is reset under the tension of the second spring 511, and the sealing plate 521, the second connecting rod 513 and the third connecting rod 514 are reset under the tension of the third spring 522. The pressure received by the pressure switch 526 fails to reach the switch opening pressure, and the external sewage suction device stops working. When the first protrusion 58 moves upward along the slope structure of the upper part of the track plate 59, the movable plate 55, the movable groove 56 and the first protrusion 58 move to the right under the tension of the first spring 57, and the movable groove 56 gradually cooperates with the collecting pipe 54 to dredge.

When sewage discharge is required, the telescopic rod 42 is started, one end of the telescopic rod 42 is extended, and the connecting block 43 is driven to move downward, thereby driving the movable plate 52 to move downward. When the first protrusion 58 moves and contacts the vertex of the second protrusion 512, the telescopic rod 42 stops extending; after sewage discharge is completed, the telescopic rod 42 is started again, one end of the telescopic rod 42 is shortened, and the connecting block 43 is driven to move upward, thereby driving the movable plate 52 to move upward. When the movable groove 56 gradually cooperates with the collection pipe 54 to clear, one end of the telescopic rod 42 stops shortening.
