AI Technical Summary
Traditional spiral sand separators have high maintenance costs, mainly because large-diameter sand and gravel rub against the spiral blades and need to pass through the spiral conveying channel throughout the process, resulting in severe wear and frequent maintenance.
A spiral sand-water separator is designed, which uses a V-shaped inclined filter screen to separate small-diameter sand and gravel. The separator is divided into a first and a second spiral separator, which are used to transport sand and gravel of different diameters respectively. The second spiral separator can be replaced independently to reduce wear.
The optimized design of the separator reduces the transportation path of large-diameter sand and gravel, lowers the maintenance frequency, reduces maintenance costs, and improves the convenience of maintenance.

Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to sand water treatment field, especially a kind of helical sand water separator. BACKGROUND
[0002] The working principle of helical sand water separator is mainly based on physical separation technology, especially using the principle of gravity settling and spiral conveying. When the sand-water mixture enters the water tank from the water inlet pipe, the particles with higher specific gravity in the mixture (such as sand particles) will sink and deposit at the bottom of the spiral groove due to their own weight. Under the push of the spiral, it continues to move up a distance after leaving the liquid surface, and finally the sand particles fall into other conveying devices at the discharge port relying on their own weight, while the supernatant continuously flows out from the drain pipe, thereby achieving the purpose of sand and water separation.
[0003] The traditional helical sand water separator has a group of discharge ports, which are located at the bottom of the spiral conveying mechanism. All sand and gravel need to pass through the entire spiral conveying channel to be discharged from the discharge port. Large-diameter sand and gravel have more friction with the spiral blades, and the entire spiral blade needs to be replaced after a period of operation, which is high in maintenance cost. SUMMARY
