Purpose:

CF type rotary solid-liquid separator (also known as rotary grid decontamination machine) is an advanced water treatment solid-liquid separation equipment, mainly used at the inlet of urban sewage treatment plants, residential sewage pretreatment devices, municipal rainwater/sewage pump stations, water plants, and power plant cooling water. This equipment is also widely used in water treatment projects in various industries such as textile, printing, food, aquatic products, papermaking, brewing, slaughtering, leather making, etc. It is an ideal solid-liquid separation equipment in the water treatment industry.

Structure and working principle

The equipment adopts a rotary type, consisting of a special shaped plow shaped rake tooth arranged in a certain assembly sequence on the horizontal axis to form a rake tooth chain. According to the water flow rate, it is assembled into different gaps and installed at the entrance of the pump station or water treatment system. When the driving device drives the rake tooth chain to move from bottom to top, the debris in the water is picked up by the rake tooth chain, and the liquid flows through the grid gap. After the equipment rotates to the upper vertex, the rake tooth chain changes its running direction and moves from top to bottom. The material falls off from the rake tooth by its own weight. When the target tooth rotates from the back to the bottom of the equipment, it starts to run continuously in a loop, continuously cleaning debris from the water and achieving solid-liquid separation. The purpose.

Main features

1. The driving device is directly driven by a cycloidal pinwheel or helical gear type reduction motor, which has the characteristics of low noise, compact structure, and smooth operation;

2. The rack is an integral frame structure with strong rigidity, easy installation, and low daily maintenance workload;

3. There are two specifications for the target teeth, with a coarse grid target tooth pitch of t=150mm and a fine grid target tooth pitch of t=100mm;

4. The equipment is easy to operate and can be directly controlled locally/remotely for operation;

5. To prevent accidental overload, mechanical shear pins and overcurrent dual protection are installed to ensure safe and reliable operation of the equipment;

6. When the width of the equipment is ≥ 1500mm, parallel connection will be adopted to ensure the overall strength of the equipment.
