Description

Technical Field

[0001] The utility model relates to the technical field of mineral processing equipment, in particular to an abnormality detection device for cyclone classification. Background Art

[0002] A cyclone is a widely used centrifugal classification device. During operation, slurry is fed tangentially into the cyclone through a feed pipe at a constant pressure, causing it to rotate at high speed around its axis. Due to varying centrifugal forces, the media and particles of varying density and size in the slurry experience varying speeds, accelerations, and directions of motion within the cyclone. Coarse, heavy particles experience a strong centrifugal force and are flung toward the walls, spiraling down to the bottom. They are then discharged from the grit outlet along with some of the media, becoming the sediment. Fine, light particles experience less centrifugal force and are carried to the center, where they are discharged from the overflow pipe along with the majority of the media, becoming the overflow.

[0003] Cyclone anomalies are primarily caused by changes in factors such as ore properties, feed pressure, slurry concentration, and feed rate, which affect the cyclone's operating efficiency. These factors can disrupt the cyclone's original control balance, affecting the cyclone's classification efficiency and causing changes in the overflow particle size of the slurry discharged from the overflow pipe. Therefore, it is necessary to design a cyclone classification anomaly detection device to promptly determine whether the cyclone's control balance has been disrupted. Utility Model Content

[0018] Furthermore, the driving part includes a motor 6 mounted on the fixed frame 3, a driving disk 61 is provided on the output shaft of the motor 6, an eccentric column 62 is provided on the driving disk 61, a connecting plate 7 is rotatably provided on the eccentric column 62, and a fixed shaft 52 rotatably connected to the connecting plate 7 is provided on one side of the screen bucket 5. The motor 6 drives the driving disk 61 to rotate, and the driving disk 61 drives the eccentric column 62 to move. The eccentric column 62 drives the screen bucket 5 to reciprocate on the guide rail 4 through the connecting plate 7, thereby accelerating the discharge of the slurry inside the screen bucket 5.

[0019] Furthermore, the mounting frame 1 is provided with a guide rod 31 which movably passes through the upper surface of the fixing frame 3 and can play a role in guiding and limiting the fixing frame 3 .

[0021] Furthermore, evenly distributed sieve holes are provided at the bottom and the lower end of the inner side surface of the screen bucket 5 to facilitate the discharge of the ore slurry inside the screen bucket 5.

[0022] The weighing platform 2 and the motor 6 used in the present invention are both commonly used electronic components in the prior art. Their working methods and circuit structures are well-known technologies and will not be described in detail here. The weighing platform 2 is preferably a flat weighing platform.

[0023] When using:

[0024] The slurry overflowing from the cyclone is discharged into the screen bucket 5 through the overflow pipe and discharged through the screen bucket 5. During this process, the motor 6 drives the drive disc 61 to rotate, and the drive disc 61 drives the eccentric column 62 to move. The eccentric column 62 drives the screen bucket 5 to reciprocate on the guide rail 4 through the connecting plate 7, thereby accelerating the discharge of the slurry inside the screen bucket 5.

[0025] When the control balance of the cyclone is destroyed and the concentration of the slurry discharged from the overflow pipe increases, large particles of ore will enter the screen bucket 5, thereby blocking the screen holes and slowing down the discharge rate of the slurry from the screen bucket 5, causing more slurry to remain in the screen bucket 5 in real time. At this time, the weight measured by the weighing platform 2 will exceed the original dynamic change range. Therefore, it can be seen that the original control balance of the cyclone is destroyed.

[0026] The utility model can weigh the ore pulp discharged from the overflow pipe, and judge whether there are large ore particles remaining in the screen bucket 5 according to the dynamic change of the weighing weight, so as to judge whether the control balance of the cyclone is destroyed. The ore pulp discharged from the overflow pipe of the cyclone can be detected in real time, and the operation is simple and easy to use.
