Centrifugal separator Structure diagram:
Horizontal screw centrifuge working principle:
The purpose of separation is to separate the solids in the mixed fluid whose specific gravity is greater than that of the liquid phase fluid from the liquid phase fluid.
When the mixed liquid has a feed port and enters the inner cavity of the high-speed rotating drum, the solids with large proportion in the mixed liquid will rapidly settle to the inner wall of the drum under the action of centrifugal force, and will be discharged from the drum body by the screw feeder from the solid phase outlet; At the same time, the liquid phase with smaller specific gravity forms an inner liquid ring under the action of centrifugal force, which is discharged from the drum through the liquid overflow port. The rotary drum and the screw feeder run at high speed at the same time. Due to a certain speed difference between the two, the solid objects settled on the drum wall are continuously pushed by the screw feeder to the liquid outlet for discharge, and the whole separation process continues.
Recumbent snail Centrifuge Structural features:
1. Large length diameter ratio, high speed. Drum cone structure with multiple angles;
2. The feeding screw adopts special anti-wear measures, which can be sprayed with a hard alloy protective layer or inlaid with a hard alloy wear plate;
3. Effectively avoid the phenomenon of double rotor high-speed rotation resonance zone. Within the design speed range, there is no obvious first and second order resonance zone phenomenon when the whole machine is running. The full vibration intensity of the bearing pedestal is controlled between 2mm/s and 4mm/s. The additional fatigue damage of equipment components caused by high-frequency vibration is avoided.
4、 differential mechanism Select the planetary gear or hydraulic differential with heavy load and large transmission ratio;
5. The bearings of the main engine shall be selected from the products of origin of world-class brands such as Sweden SKF and Japan NSK.
6. Main bearing lubrication system: A. Thin oil lubrication; B. Grease lubrication
7. Constant temperature inspection: the inspection of all finishing parts of the whole machine is carried out under constant temperature conditions to ensure that the actual processing quality meets the design accuracy requirements.
8. The GSRL high-speed feeding device, by adjusting the internal design of the spiral core tube, without reducing the centrifugal acceleration of the original separation solution, shortens the speed following time when the materials enter the centrifuge, reduces the turbulence of the swirling flow, prolongs the effective separation time of the materials in the centrifuge, improves the separation efficiency, and realizes that the processing capacity increases by 15%~25% while the speed required for separation decreases by 10%~12%. At the same time, it can increase the working pressure inside the centrifuge and inhibit the production of liquid foam.
9. The differential speed and torque can be automatically adjusted with the change of material concentration and flow;
10. Horizontal type with BD plate Spiral sedimentation centrifuge It can be used to concentrate and dewater the primary sedimentation and activated sludge of different proportions and separate the materials that are difficult to separate.
