Sewage treatment pipeline type crushing grille

Sewage treatment pipeline type crushing grille

Basic structure:

The pipeline type crushing grid is mainly composed of a driving device, a driving shaft, a driven shaft, a cutting blade group, a seal, a machine body, etc. The driving device drives the driving shaft to rotate, and at the same time, the driving shaft drives the driven shaft to rotate through precision gears, causing the blades fixed on the two shafts to rotate in reverse, thereby biting, squeezing, cutting and crushing solid objects into small particles.

Control system:

1. Configure PLC with LCD Chinese display and reserved MODBUS communication interface for remote control;

2. The blocking current, number of reversals, and reversal time can all be freely set;

3. Equipped with motor leakage, overload, overheating, short circuit, and phase loss protection;

4. The equipment operating status, motor load current, and fault status can all be displayed in real-time and queried historically.

Civil structure

The crushing type grille has a compact structure, small volume, light weight, and small footprint, while traditional mechanical grilles have a large volume and require a large channel to be reserved for installation. The crushed grille can greatly reduce the construction quality of pump stations, decrease land use, and lower civil engineering costs.

Easy installation and suitability

The crushing type grille comes with a fixed frame, which can be installed by simply placing it into a pre installed frame (customized according to the size of the channel), suitable for various sizes of channels. However, traditional mechanical grilles have a large volume and are difficult to install, requiring large lifting equipment for lifting and installation.

usage

The crushing type grille motor has low power, energy saving, balanced operation, and low noise. It also comes with a PLC system, forming a complete operation system that can provide switches, operation indicators, and fault alarm interfaces for remote control systems. Monitoring administrators only need to observe the overall operation of the equipment in the remote control room. Although traditional mechanical grilles can also use programmable controllers to control the movement of the rake bucket, they cannot provide specific operation feedback to the remote control system.

The pipeline pulverization type grating machine is suitable for sewage treatment applications with relatively low flow rates. The pipeline pulverizer is installed in a flange style on the pipeline to transport solid substances in the medium. Suspended solids and slender fibers are crushed into small particles. In sewage treatment, it is mainly used in sludge digestion tanks, reducing the amount of sludge in the digestion cycle, accelerating the digestion speed, and reducing the sludge circulation time. The pipeline crusher is suitable for the vast majority of existing direct discharge equipment or pipeline applications, and does not require additional pipeline or channel system modifications.

The pulverization type grid cleaning machine is suitable for water treatment systems such as sewage treatment and rainwater pump stations, which pulverizes solid substances in sewage into particles. It is a new type of cleaning equipment that solves the harm of solid particles to environmental protection equipment and is an ideal substitute for traditional grid cleaning machines. Traditional grid cleaning machines are mostly semi underground, using ordinary grid cleaning machines to intercept and salvage suspended and floating solids in sewage. After the garbage is salvaged, it needs to be transported through spiral conveying equipment or manual cleaning, which will cause secondary pollution to the surrounding environment.

Advantages:

1. Integrated design, compact equipment, flexible structure and installation options, suitable for channel selection of various sizes;

2. Adopting low-speed operation, low power consumption, minimal wear, and utilizing the principle of differential operation of cutting blades, the tearing effect of garbage is enhanced;

3. Special blade structure design, with strong self-cleaning ability, no entanglement or accumulation of debris, ensuring efficient cutting ability and service life;

4. A reasonable transmission structure makes it easy to replace cutting blades, simple to maintain, and reduces maintenance costs;

5. Equipped with a reliable protection system, it can effectively protect the equipment from damage when overloaded;

6. Imported motor reducers have improved the reliability of equipment use,

7. Specially customized mechanical sealing system that can work for long periods of time in harsh sewage environments.
