Technical description of the drum mechanical grille
In the process of treating urban sewage and industrial wastewater, the rotary drum mechanical grille plays a crucial role in the mechanical pretreatment stage by effectively separating and removing floating and settleable materials. With its excellent mechanical performance, stable operation, and relatively low maintenance cost, it has become an essential component in many treatment facilities. Today, Yixing Chengcheng provides an in-depth overview of the technical features and specifications of the drum mechanical grille.
**Technical Features of the Drum Mechanical Grille:**
First, the drum mechanical grille is widely applicable. Its grid spacing can range from 0.6mm to 5mm, making it suitable for various types of wastewater. It can handle a maximum flow rate of up to 6624 m³/hour, which makes it ideal for large-scale applications.
Second, it uses advanced technology that ensures no secondary pollution. The system integrates filtration, transmission, and pressing functions, allowing the discharged material to have a solid content of 40-50%, which is efficient and environmentally friendly.
Third, the operating cost is relatively low. The entire system consumes minimal power, making it energy-efficient and cost-effective for long-term use.
Fourth, it is highly resistant to corrosion and has a long service life. The drum mechanical grille is constructed entirely from stainless steel (304 grade), ensuring durability even under harsh conditions.
**Technical Parameters of the Drum Mechanical Grille:**
- Single design flow: 815 L/s
- Drum diameter: 1800 mm
- Gap size: 5 mm
- Motor power: N = 3 kW
- Protection level: IP55
- Insulation class: Class F
- Operating system: 24 hours per day, continuous operation
**Main Structure of the Drum Mechanical Grille:**
The drum mechanical grille consists of several key components, including the grating drum assembly, screw shaft, conveying press tube, mounting bracket, flushing device, and electric control box. These parts work together to ensure smooth and efficient operation.
