FLUITECO Grit washer – CDL

Vertical pyrolysis centrifuges are a suitable technological solution to complete the separation process performed by receiver centrifuges. Centrifugal separators, with very high rotational speeds, can reach a centrifugal force of up to 10,000 grams. This very high centrifugal force is a key element that allows the separators to remove solid particles that have not been successfully trapped in previous separation steps. In addition, the achievable performance levels depend on many factors: structural (type and design of the disc, internal volume, surfaces and discharge devices) and operational (flow rate, product characteristics, amount and type of solid content, temperature).

 

The product enters the upper part of the separator through the feed tube for clarification and is then subjected to centrifugal force and is forced to pass through hundreds of internal disks. The combined operation of the centrifugal force combined with the internal disks leads to the separation of solid particles that deposit on the drum wall and are then automatically and intermittently discharged. Fluids rise to the top of the drum and are continuously discharged through free outlets or centrifugal pumps.

Description

The CDL sand washer is for washing and separating the fine sand in the sewage at the same time. The screw is usually attached directly to the motor flange branch. The bottom of the funnel is equipped with a sand washing system that injects clean water in a reciprocating stream to remove organic matter from the sand for reuse in the cement/concrete industry.

The main work of the device:

The effluent enters the funnel through the inlet spectrum and the rotational motion of the central stirrer keeps it in motion and facilitates the deposition of sand while maintaining it. The suspension of organic matter leads down the funnel, and clean water flows in the opposite direction to wash away the sand and facilitate the floating of the organic matter. Organic matter is then discharged at regular intervals through a dedicated exhaust duct. The constant rotational motion of the water mass allows the sand to pass from the hopper to the drain screw, which carries it to the drain path.
