Product Description

1, Equipment introduction
1. Working principle
    The sand water separator is used in the grit chamber of the sewage treatment plant to separate the sand water mixture discharged from the grit chamber. The sand water mixed liquid is input into the water tank from the top of one end of the separator. The sand particles with medium and heavy weight in the mixed liquid will be deposited at the bottom of the groove due to gravity. Driven by the screw, the sand particles will rise along the inclined U-shaped groove bottom and continue to move for a certain distance after leaving the liquid level. After the sand particles are fully dehydrated, they will be discharged to the sand bucket through the sand discharge port; The water separated from the sand is discharged from the overflow port and sent to the inlet pool in the plant. The separation efficiency can reach 96% ~ 98%, and particles with particle size ≥ 0.2mm can be separated.
2, Description of main structure and material:
    The machine is composed of organism, integrated reducer driving device, inclined sand discharge tank, wear-resistant nylon lining plate and shaftless screw. Generally, the installation angle of the equipment is optional between 20 ° ~ 30 °.
1. Body:
    The structure is stainless steel welding, equipped with conical groove body, groove body cover, water inlet and overflow port, equipped with spiral groove body, and the section of grid bar is U-shaped. Whole welding assembly to eliminate welding stress. The U-shaped tank body is lined with wear-resistant nylon plate and installed with special pressure block.
2. Main transmission part:
    Including drive motor, reducer and transmission bearing housing. The motor reducer is xled42-0.75kw, which is connected with the transmission bearing housing flange. The transmission bearing shell is a combination of deep groove ball bearing and thrust ball bearing. The transmission main shaft is connected with the screw shaft flange and set with universal connection.
3. Spirochete:
    The spiral body is a shaftless spiral made of stainless steel 304 and made by hot rolling to eliminate internal stress.
    The processing capacity of a single unit is 18 ~ 126m3 / h The baffle V-shaped weir plate flows out to ensure that the sand content in the water is small Shaftless spiral sand discharge to avoid blockage and overload The U-shaped liner is made of high-quality engineering plastics with good wear resistance Low speed operation, low energy consumption and low wear Spiral body material: high strength alloy steel, stainless steel SS304 or SS316L Shell material: stainless steel SS304 or SS316L Optional: cyclone separator for pre separation
