The LWS-650 × 2300 spiral discharge settling centrifuge

The LWS-650 × 2300 spiral discharge settling centrifuge differential manufacturer horizontal spiral discharge settling centrifuge (hereinafter referred to as the centrifuge) can be used in the process of sludge dewatering and sludge concentration dewatering in sewage treatment to dewater or concentrate the flocculated sludge.

The fixed end main bearing adopts deep groove ball bearings. It can simultaneously carry loads in both radial and axial directions. The spiral bearing adopts a combination of NG type roller bearing and thrust bearing, which respectively bear the radial and axial loads of the spiral. When the solid content in the suspension to be processed is high, it is time to demonstrate the horizontal spiral centrifuge, which can complete various processing tasks through clarification, concentration, separation, and cleaning. The high-speed rotating drum generates centrifugal force to intercept solid particles in the suspension inside the drum, and automatically discharges them outside the machine under the action of force; At the same time, under the action of centrifugal force, the liquid in the suspension is thrown out through the filtering medium and the small holes of the drum, thus achieving the purpose of liquid-solid separation and filtration. The horizontal spiral centrifuge consists of a frame, hood, main bearings, screws, drum, safety protection system, differential, control system, and transmission system..

The main bearings and spiral bearings of the centrifuge are lubricated with grease. Lubricate with regular grease. The main bearing needs to be refilled every 24 hours, while the spiral bearing can be refilled every 3 months. If long-lasting grease is used, the main bearing can be refilled every 1500 hours. Solid liquid separation is an essential step in the industrial treatment of manure in large-scale dairy farms. The commonly used solid-liquid separation methods include sedimentation, mechanical separation, evaporation tank separation, flocculation separation, and dehydration separation, among which mechanical separation is the most effective separation method; The most commonly used mechanical separation equipment includes screening equipment (inclined plate screen, vibrating screen), centrifugal separation equipment, and pressure filtration equipment (belt, spiral extrusion). The significance of solid-liquid separation lies in two aspects: firstly, reducing the pollutant content in feces through pretreatment, and lowering the pressure and cost of subsequent treatment processes; Secondly, it is necessary to prevent large solids or debris from entering the subsequent processing stages, causing equipment blockage or damage.

Strict real-time display monitoring and alarm of the operating status of the bearings can be carried out. If any abnormal situation occurs, timely alarm and correction of deviations during operation can be made to prevent bearing failures in the centrifuge, ensure safe, stable and reliable operation of the centrifuge, and extend the service life of the host bearings. The main bearing of a horizontal screw centrifuge generally has a fault free operation time of more than 2 years.
