After nearly two years of technological breakthroughs, Hubei Hongfeng Environmental Protection Equipment Technology Co., Ltd. has independently developed the LWD-D series horizontal spiral discharge sedimentation centrifuge. It has applied for 2 national invention patents and obtained 6 utility model patents. Extensive testing has been conducted in fields such as petrochemicals, pharmaceuticals, food, mining, metallurgy, and environmental protection (industrial wastewater, municipal sludge, aquaculture wastewater). Through repeated testing, the product not only exceeds the world's best levels in speed and separation factors but also adds a crushing and drying function, increasing the solid content rate by 15%, reaching internationally advanced levels.

Design Showcase

· A glass viewing window is added on the side for easy observation of internal gauge readings.
· Nitrogen gas springs support the upper protection opening, facilitating equipment debugging and maintenance.

Motor Protection and Noise Reduction

· Both left and right motor protection panels can be flipped open for easy installation and maintenance.

Control Cabinet

Integrated Shell Opening and Closing

· Mushroom-shaped sealing strips are installed on the shell flange for effective sealing.

Product Features

1. The casing adopts a pull-rod device, making it easy to open and close for convenient maintenance. Equipped with an internal cleaning device, it ensures the cleanliness of the process chamber, especially suitable for handling multiple products to avoid cross-contamination of different materials.
2. During operation, the machine exhibits no significant first or second-order resonance within the designed speed range. The vibration intensity at the bearing seat is controlled between 2mm/s and 4mm/s, avoiding additional fatigue damage to components caused by high-frequency vibration and beat vibration.
3. The spiral uses a BD baffle squeezing structure, making the clear liquid clearer and the discharged solids drier. An accelerated wear-resistant strip is designed inside the spiral core tube to accelerate the material while preventing wear on the inner wall of the spiral core tube material bin.
4. The lubrication system uses forced circulation of thin oil, allowing higher speeds, larger separation factors, and better separation effects.
5. The operating system adopts an HMI human-machine interface, enabling various operations of the centrifuge through the interface and real-time monitoring of its working status. It provides protection against overload, short circuit, and phase loss in the circuit and frequency converter. It has a comprehensive monitoring and alarm system that monitors operating parameters such as centrifuge speed, bearing temperature, and overall vibration in real time, and alarms and shuts down when parameters are abnormal, ensuring the safety of personnel and equipment.
6. A specially designed damping device eliminates resonance caused by liquid ring stall during startup and shutdown. The centrifuge main bearing protection device provides protection for the main rotating body in case of main bearing failure.
7. Currently, all industries using centrifuges involve intensive manual operation, poor safety protection, and are time-consuming, labor-intensive, and costly. The LWD-D series addresses these issues, aiming to achieve unmanned workshops and realize the ideal goal of high-yield, efficient, and safe production.

Comparison of Product Appearance Before and After Design

First-Generation Product (Three-Leg Type)

Pain points before design: high equipment vibration, multiple safety hazards, failure to meet environmental standards, labor-intensive, non-compact appearance, and subject to national bans.

Pre-Design Product

Second-Generation Product (Flat Plate Four-Leg Type, Manual Loading and Unloading)

Pain points before design: small processing capacity, labor-intensive (requiring multiple people per machine), low speed, poor separation effect.
