Description

Technical Field

[0001] This utility model relates to the field of hydrocyclone technology, specifically a hydrocyclone with a spliced ​​inner liner. Background Technology

[0002] A hydrocyclone is a device that uses centrifugal force to separate materials. When the two-phase mixture to be separated enters the hydrocyclone tangentially from its periphery under a certain pressure, it generates intense three-dimensional elliptical strong rotating shear turbulence. Due to the size difference between coarse and fine particles, they are subjected to different magnitudes of centrifugal force, centripetal buoyancy, and fluid drag. Under centrifugal sedimentation, most of the coarse particles are discharged through the underflow port of the hydrocyclone, while most of the fine particles are discharged through the overflow pipe, thus achieving the purpose of separation and classification. It is widely used in mining, chemical, environmental protection, energy and other fields.

[0003] The hydrocyclone contains an inner liner, the material of which directly affects its wear resistance, corrosion resistance, service life, and separation efficiency. This is especially true when processing high-hardness, high-concentration, or corrosive media. A common practice is to connect the inner liners sequentially, but the liner has flat openings at both the top and bottom, resulting in large gaps at the joints. Therefore, we propose a hydrocyclone with a spliced ​​inner liner to address these issues. Utility Model Content

[0004] The purpose of this invention is to provide a hydrocyclone with a spliced ​​inner liner to solve the problems mentioned in the background art.

[0006] As a further technical solution of this utility model, the feed box, upper cone, lower cone and sand settling nozzle are connected in sequence by a sealing ring, and an inner liner is provided inside the feed box, upper cone, lower cone and sand settling nozzle.

[0008] As a further technical solution of this utility model, a feed port is installed on the right side of the feed box, an overflow port is installed on the top of the feed box, a sand settling port is provided at the bottom of the sand settling nozzle, and a connecting lug is installed on the outer side of the upper cone.

[0009] As a further technical solution of this utility model, the outer side of the liner is provided with a rubber layer, the inner side of the liner is provided with a ceramic layer, and the inner side of the liner is provided with a collision protection net.

[0010] As a further technical solution of this utility model, the anti-collision net covers the inside of the liner and contacts the ceramic layer, and the outside of the liner is covered with a rubber layer.

[0011] As a further technical solution of this utility model, there are snap-fit ​​blocks around the front end of the feed port, the front end of the feed port is covered with a filter screen, and snap-fit ​​grooves are opened around the filter screen.

[0012] As a further technical solution of this utility model, the snap-fit ​​grooves opened around the filter screen are snapped into the snap-fit ​​blocks around the front end of the feed port, and the snap-fit ​​blocks rotate inside the feed port to fix the filter screen inside the feed port.
