Description

TECHNICAL FIELD

[0002] It is known that the heavy medium ore dressing suspension circulating purification energy-saving equipment is a key device in the heavy medium ore dressing process, which is composed of a medium removal screen, a magnetic separator and a thickener. The product and the suspension are separated through the medium removal screen, the magnetic separator recovers the magnetic weight, and the thickener thickens the dilute suspension, realizing the recycling and purification of the suspension, maintaining the stability of the suspension, meeting the requirements of the ore dressing process, reducing energy consumption and improving resource utilization efficiency.

[0003] When the heavy medium ore dressing suspension circulating purification energy-saving equipment is used, it first enters the medium removal mechanism. Most of the qualified suspensions are separated out through the screening and water washing of the medium removal screen and directly enter the circulating system. The weight and fine coal slurry adhered to the product are washed down to form a dilute suspension. The dilute suspension enters the subsequent treatment process. If it is a magnetic suspension, it will first pass through the magnetic selection mechanism to recover the magnetic weight by magnetic force. The recovered high-density suspension can be directly returned to the separation operation circulating system or used as supplementary medium in the high-density medium barrel. If the dilute suspension contains more coal slurry and other impurities, it may first pass through the thickening mechanism for concentration to remove part of the water and impurities. For some special magnetic suspensions, a pre-magnetizer and a demagnetizer are also needed to ensure the stability of the weight in the suspension, so that the entire circulating purification system can operate efficiently and stably, and finally realize the recycling and energy-saving of the suspension in the heavy medium ore dressing process.

[0004] However, in the prior art, the medium removal mechanism of some heavy medium ore dressing suspension circulating purification energy-saving equipment has the problem of excessive vibration during operation. When the vibration amplitude far exceeds the normal range, not only will the efficiency and accuracy of medium removal be reduced, affecting the recycling effect of the suspension, but also will cause additional impact and wear on other parts of the equipment, greatly shorten the service life of the equipment, increase the maintenance cost and downtime of the equipment, and thus adversely affect the continuity and stability of the entire ore dressing production.
