Description

Technical Field

[0001] This utility model relates to the field of hydrocyclone technology, and in particular to a double-layer hydrocyclone. Background Technology

[0002] Early hydrocyclones had simple structures, mostly using a single swirling chamber and a single conical body for fluid separation. This resulted in insufficient acceleration space and poor separation quality. With the development of industrial technology and fluid mechanics, the fluid swirling process became more precise, leading to the development of multi-stage hydrocyclones. However, the stacking of stages at the bottom layer easily causes blockage, resulting in low efficiency. Currently, a type of double-layer hydrocyclone suffers from insufficient acceleration space, poor separation quality, and easy blockage during fluid separation. Therefore, these technical problems need to be solved. Utility Model Content

[0024] Working principle: In the use of this utility model, the fluid to be separated is first propelled tangentially into the cyclone chamber shell 1 through the feed channel 2 connected to the pressurized feed pipe, generating a high-speed cyclone field. At this time, the fluid with higher density moves outward and the fluid with lower density moves inward along the axis. As the fluid reaches the upper conical shell 5, the middle conical shell 6, and the lower conical shell 7, it is accelerated, forming a negative pressure external vortex flow field, causing the denser substances in the fluid to be discharged from the sand discharge nozzle 8. At the same time, an internal vortex flow field is formed inside, causing the less dense substances to move upward and exit through the overflow straight pipe 4. If the lower sand discharge nozzle 8 becomes blocked during the fluid separation process, the motor 18 is started to drive the worm gear 17 to rotate. As the worm gear 17 rotates, it drives the turbine 16 to rotate, causing the shaft 15 to rotate. As the shaft 15 rotates, it drives the gear 14 to rotate synchronously, causing the cylindrical rack 12 to move upward and lift the conical unblocking block 11 towards the sand discharge nozzle 8 to disperse the blockage. At the same time, the motor 18 is intermittently reversed to make the conical unblocking block 11 move up and down to accelerate the unblocking. After the unblocking is completed, the conical unblocking block 11 is reset and the power is turned off.
