[0002] Sewage treatment is one of the important links in environmental protection and resource utilization. As an important equipment in sewage pretreatment, the basic principle of hydrocyclone desander is to use hydrocyclone to quickly settle and separate solid particles in sewage. However, the existing hydrocyclone desander has the following problems when treating high-concentration sewage, fine particles and long-term operation:

[0003] Low treatment efficiency: For high-concentration sewage or fine particles, the existing hydrocyclone desander has limited treatment efficiency and is difficult to completely remove solid particles, which affects subsequent treatment links.

[0004] Poor treatment effect: The existing hydraulic cyclone desander has a simple structure. During the cyclone treatment of water, fine sand and gravel are easily mixed into the middle beam water flow and discharged, resulting in poor purity of the treated water.

[0005] Low water outlet efficiency: The purified water is discharged from the center end pipe through the cyclonic motion of the water, and sand, gravel, soil, etc. and most of the water are discharged through the tail port. Most of the water escapes and cannot be discharged from the clean liquid port, resulting in less clean water volume.
