Product details
WL-650 horizontal spiral discharge settling centrifuge
Working principle
The purpose of separation is to separate solid substances in the mixed fluid with a specific gravity greater than that of the liquid phase fluid from the liquid phase fluid.When the mixed liquid enters the inner cavity of the high-speed rotating drum through the feeding port, the solid substances with higher specific gravity in the mixed liquid quickly settle to the inner wall of the drum under the action of centrifugal force, and are discharged from the drum body through the solid phase outlet by the spiral pusher; At the same time, the liquid phase with a smaller specific gravity forms an inner liquid ring under the action of centrifugal force, and is discharged from the outside of the drum through the liquid overflow port. The drum and the screw pusher operate at high speed simultaneously, and due to the certain speed difference between the two, the solid substances settled on the drum wall are continuously pushed by the screw pusher to the outlet for discharge, and the entire separation process continues.

Structural characteristics
1. Large aspect ratio and high rotational speed. A drum cone structure with multiple angles;
2. The feeding spiral adopts special wear-resistant measures, which can be sprayed with hard alloy protective layer or embedded with hard alloy wear-resistant sheet;
3. Effectively avoiding the phenomenon of resonance zone in high-speed rotation of dual rotors
Within the designed speed range, there is no obvious first-order or second-order resonance zone phenomenon during the operation of the whole machine, and the full vibration intensity of the bearing seat is controlled between 2mm/s and 4mm/s. Avoiding additional fatigue damage to various components of the equipment caused by high-frequency vibration.
4. Differential selection
Choose planetary gears or hydraulic differentials with heavy loads and high transmission ratios;
5. Selection of host bearings
Select products from international top brands such as SKF from Sweden and NSK from Japan.
6. Main bearing lubrication system
A、 Thin oil lubrication
B、 grease
7. Constant temperature inspection
All precision machined components of the entire machine are inspected under constant temperature conditions to ensure that the actual machining quality meets the design accuracy requirements.
8. 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, the following time of the material entering the centrifuge is shortened, the turbulence of the vortex is reduced, the effective separation time of the material inside the centrifuge is extended, and the separation efficiency is improved. This achieves a 15% -25% increase in processing capacity while reducing the required separation speed by 10% -12%. At the same time, it can increase the working pressure inside the centrifuge and inhibit the production of liquid foam.
9. A microcomputer control system that can automatically adjust differential speed and torque with changes in material concentration and flow rate;
10. The horizontal spiral sedimentation centrifuge with BD board can concentrate, dehydrate and separate difficult to separate materials from various ratios of primary sedimentation and activated sludge.
