The desander cyclone is different from the ordinary cyclone equipment. It is generally used in coal preparation. It adopts pressureless feeding. It has the characteristics of large capacity, high efficiency and simple process.
When the hydrocyclone is used, the specific gravity of feed and the stability of coal quality should be checked from time to time, and keep close contact with operators. Before coal feeding, the specific gravity of suspension should be adjusted to an appropriate range, and the information should be mastered in the whole process to avoid coal washing with clean water. Coal can be carried only after the feeding pressure is stable, and the set pressure is maintained to ensure the uniformity of feeding.
Check the pipeline patency frequently, observe whether the overflow and discharge of hydrocyclone are within the normal range to ensure that the raw coal does not contain large materials. In the process of checking the liquid level, the amount of new medium added can be reduced and the number of times can be increased. If the density of the separation is too high, the liquid level can be reduced by flow and the density can be adjusted by adding fresh water.
The operators who use the desander cyclone should wear safety equipment when entering the main plant. If the equipment is damaged and needs to be repaired, relevant power transmission procedures should be handled in advance, and relevant personnel should be arranged around for monitoring. When observing the flow rate of the equipment, if it is confirmed that it is not caused by the wear of the equipment, but the abnormal feeding, the relevant department shall be informed to adjust and deal with it to ensure the normal circulation.
For the maintenance of desander hydrocyclone, check the inlet and outlet during operation to ensure that the blockage can be found and solved in time. Regularly check the wear condition of the equipment, and replace the parts that are seriously damaged and may even affect the use to ensure the separation effect. Be careful not to knock on the flange when replacing it.
Staff inspection to avoid foreign matter into the cyclone equipment, to avoid accidental damage.
