Model representation
Features:
This product is an improved design based on the use of this type of product at home and abroad. It solves the shortcomings of inconvenient replacement of the liner and non-adjustable axial position of the spiral. Its features are as follows:
1. The separation efficiency can reach 96%~98%, and particles with a particle size of ≥0.2mm can be separated;
2. It adopts shaftless spiral and no bearings in water, making it easy to maintain;
3. Compact structure and light weight;
4. The key product of the new transmission device, the reducer, is an advanced shaft-mounted type that does not require a coupling and is easy to install and align;
5. The liner is quick-installed and easy to replace;
6. The axial position of the spiral is adjustable, making it easy to adjust the safety gap between its tail and the box wall.
Structure and working process:
The spiral sand-water separator consists of a shaftless spiral, a liner, a U-shaped groove, a water tank, a guide plate, an outlet weir and a driving device.The sand-water mixture is input into the water tank from the top of one end of the separator. The heavier ones in the mixed liquid, such as sand, will be deposited at the bottom of the tank. Under the push of the spiral, the sand will be lifted along the inclined bottom of the tank and continue after leaving the liquid surface. After the sand is fully dehydrated, it is discharged to the sand bucket through the sand discharge port, and the water separated from the sand water is discharged from the overflow port and sent to the inlet pool in the factory.
The main technical parameters:
Ordering requirements for spiral sand-water separator:
1. Write the full name according to the model number;
2. Usage environment (indoor, outdoor and other);
3. If a reinforced concrete water tank is used, the engineering design data of the relevant parts should be provided.
