Description

Technical Field

[0001] This utility model relates to the field of thickener technology, and in particular to a high-efficiency centrifugal sedimentation device for thickeners. Background Technology

[0002] A thickener is a solid-liquid separation device based on gravity settling. It is typically a shallow cylindrical tank with a conical bottom, constructed using concrete, wood, or welded metal plates as structural materials. It can concentrate mineral slurry with a solids content of 10%–20% into an underflow slurry with a solids content of 45%–55% through gravity settling. The thickened underflow slurry is discharged from the underflow outlet at the bottom of the thickener by the action of a rake that operates at a slow speed (1 / 3–1 / 5 r / min) installed inside the thickener. Before the material enters the thickener, it needs to be pre-treated using a centrifugal settling device to obtain a higher concentration of mineral material.

[0003] Existing settling devices cannot effectively limit the movement of the equipment when separating mineral materials, which causes the equipment to shift and shake, leading to equipment damage. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a high-efficiency centrifugal sedimentation device for thickeners.

[0005] This utility model is achieved using the following technical solution: a high-efficiency centrifugal sedimentation device for a thickener, comprising an upper cylinder, a connecting plate at the bottom of the upper cylinder, a lower cylinder at the bottom of the connecting plate, a downflow port at the bottom of the lower cylinder, a connecting plate at the bottom of the downflow port, an annular tube at the top of the upper cylinder, an inlet pipe at the left end of the upper cylinder, an insertion pipe inside the upper cylinder, a rotating barrel on the surface of the insertion pipe, a connecting block on the surface of the rotating barrel, a high-pressure nozzle at the bottom of the connecting block, a water pump at the top of the annular tube, a motor at the front end of the water pump, a water inlet connecting pipe at the top of the water pump, and a limit block on the surface of the upper cylinder.

[0006] As a further improvement to the above solution, the bottom end of the upper cylinder is fixedly connected to the top end of the connecting plate, the bottom end of the connecting plate is fixedly connected to the top end of the lower cylinder, the top end of the lower outlet is fixedly connected to the bottom end of the lower cylinder, and the top end of the connecting plate is fixedly connected to the bottom end of the lower outlet.

[0007] Through the above technical solution, the upper cylinder, as the main upper structure of the entire device, provides a stable installation space and support frame for internal parts such as insertion tubes and rotating drums. The connecting plate firmly connects the upper cylinder and the lower cylinder, ensuring the integrity of the upper and lower cylinder structures. This prevents the upper and lower parts from separating or shaking during the operation of the entire device. The lower cylinder works in conjunction with the upper cylinder to extend the flow path of the material in the device, which is conducive to the continuous centrifugal sedimentation process of the material and improves the sedimentation effect. The connecting plate further stabilizes the structure of the lower outlet and prevents the lower outlet from deforming or being damaged due to pressure or other external forces during the material outflow process.

[0008] As a further improvement to the above solution, the top end of the upper cylinder is fixedly connected to the bottom end of the annular tube, the right end of the feed tube is fixedly connected to the left end of the upper cylinder, and the top end of the insertion tube is fixedly connected to the top end of the inner cavity of the upper cylinder.

[0009] Through the above technical solution, the annular pipe serves as a water distribution channel, which evenly distributes the water pumped from the water supply pump to the relevant parts inside the device, ensuring that the places inside the device that need water can receive a stable water supply. The feed pipe provides a dedicated channel for the material to enter the upper cylinder, ensuring that the material can enter the device for centrifugal sedimentation treatment according to the designed process. The insertion pipe provides rotational support for the rotating barrel, enabling the rotating barrel to rotate stably around the insertion pipe, thereby realizing the function of centrifugal sedimentation.

[0010] As a further improvement to the above solution, the inner wall of the rotating barrel is connected to the surface of the insertion tube in a transmission manner, four connecting blocks are provided, one end of the four connecting blocks that is close to each other is fixedly connected to the surface of the rotating barrel, and several high-pressure nozzles are provided, the top of the several high-pressure nozzles is fixedly connected to the bottom of the four connecting blocks.

[0011] Through the above technical solution, the rotating drum generates centrifugal force by its own rotation, which promotes the separation of solids and liquids in the material. It is one of the core components for realizing the centrifugal sedimentation function. The connecting block, as the connecting component between the high-pressure nozzle and the rotating drum, securely installs the high-pressure nozzle below the rotating drum, ensuring that the nozzle can work normally during the rotation of the rotating drum. The high-pressure nozzle sprays high-pressure water, which can clean the inside of the device and prevent material residue from clogging the device. At the same time, the impact of the high-pressure water may also help the material sedimentation process.

[0012] As a further improvement to the above solution, the bottom end of the water supply pump is fixedly connected to the top end of the annular pipe, the rear end of the motor is fixedly connected to the front end of the water supply pump, and the bottom end of the water inlet connection pipe is fixedly connected to the top end of the water supply pump.

[0013] Through the above technical solution, the water supply pump provides power for the water supply, draws water from the external water source through the water inlet connection pipe, and then distributes it to relevant parts inside the device through the ring pipe. It is a key component to ensure the normal operation of the water supply system inside the device. The water inlet connection pipe, as the connecting pipe between the external water source and the water supply pump, introduces the external water source into the water supply pump and is the starting part of the entire water supply system.

[0014] As a further improvement to the above solution, four limiting blocks are provided, and the ends of the four limiting blocks that are close to each other are fixedly connected to the surface of the upper cylinder.

[0015] Through the above technical solution, the limiting block limits the upper cylinder from the outside, enhances the stability of the upper cylinder, and prevents the upper cylinder from unnecessary displacement or shaking due to the movement of internal parts or external interference during the operation of the device.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This invention utilizes a rotating drum connected to the surface of the insertion tube in the device. When material enters the upper cylinder from the feed pipe, the rotation of the rotating drum helps to centrifuge the material. This centrifugal action can accelerate the separation of solids and liquids in the material, making the sedimentation process faster. Compared with traditional thickeners that rely solely on gravity sedimentation, this greatly improves sedimentation efficiency.

[0018] The annular pipe is supplied with water by a water pump driven by a motor. Water enters the annular pipe through the inlet connection pipe and is then sprayed out through several high-pressure nozzles at the bottom of the connecting block. The high-pressure nozzles can clean the inside of the device, prevent material residue, ensure the normal operation of the device, and also help to extend the service life of the device.

[0019] This invention features fixed connections between components such as the upper cylinder, connecting plate, and lower cylinder. For example, the bottom of the upper cylinder is fixedly connected to the top of the connecting plate. This fixed connection method ensures the stability of the entire device structure. Simultaneously, four limiting blocks are provided on the surface of the upper cylinder, which further enhances the overall stability of the device, reduces shaking during operation, and thus ensures the stable execution of the centrifugal sedimentation process.

[0029] The bottom end of the upper cylinder 1 is fixedly connected to the top end of the connecting plate 15, the bottom end of the connecting plate 15 is fixedly connected to the top end of the lower cylinder 2, the top end of the lower outlet 3 is fixedly connected to the bottom end of the lower cylinder 2, and the top end of the connecting plate 4 is fixedly connected to the bottom end of the lower outlet 3.

[0030] The top end of the upper cylinder 1 is fixedly connected to the bottom end of the annular tube 5, the right end of the feed tube 6 is fixedly connected to the left end of the upper cylinder 1, and the top end of the insertion tube 7 is fixedly connected to the top end of the inner part of the upper cylinder 1.

[0031] The inner wall of the rotating barrel 8 is connected to the surface of the insertion tube 7. Four connecting blocks 9 are provided, and the ends of the four connecting blocks 9 that are close to each other are fixedly connected to the surface of the rotating barrel 8. Several high-pressure nozzles 10 are provided, and the top of the several high-pressure nozzles 10 is fixedly connected to the bottom of the four connecting blocks 9.

[0032] The bottom end of the water pump 11 is fixedly connected to the top end of the annular pipe 5, the rear end of the motor 12 is fixedly connected to the front end of the water pump 11, and the bottom end of the inlet connection pipe 13 is fixedly connected to the top end of the water pump 11.

[0033] Four limit blocks 14 are provided, and the ends of the four limit blocks 14 that are close to each other are fixedly connected to the surface of the upper cylinder 1.

[0034] The implementation principle of the high-efficiency centrifugal sedimentation device for a thickener in this embodiment is as follows: Material enters the upper cylinder 1 through the feed pipe 6. The rotating drum 8 is connected to the insertion pipe 7 via a transmission mechanism. The motor 12 drives the relevant components to rotate, causing the rotating drum 8 to rotate. The rotation of the rotating drum 8 generates centrifugal force. Under the action of centrifugal force, the solid portion of the material gathers towards the inner wall of the rotating drum 8 and moves downwards, while the liquid portion moves relatively towards the central area, achieving preliminary solid-liquid separation. The liquid after preliminary separation can be discharged through the outlet 3 at the bottom of the lower cylinder 2, while the solid portion continues to settle downwards under the combined action of gravity and centrifugal force, eventually settling further at the bottom of the device. When cleaning the device is required, the motor 12 drives the water pump 11, and water enters the annular pipe 5 through the inlet connection pipe 13, and then is sprayed out through the high-pressure nozzle 10 at the bottom of the connecting block 9. The water sprayed from the high-pressure nozzle 10 can rinse the inside of the device, including the rotating drum 8 and the inner wall of the upper cylinder 1, washing away any residual material, which is then discharged from the device through the outlet 3.
