Fine sand recovery device

summary:

The fine sand recovery device is mainly suitable for large-diameter pile foundations, non excavation construction, and anti-seepage wall projects (such as sand making slurry, pile driving slurry, and mine tailings slurry) that adopt mud wall fixation and cyclic drilling technology in modern foundation engineering construction. By thoroughly purifying the mud, it is beneficial to control the performance indicators of the mud, reduce drilling accidents, and improve the quality of drilling.

Principle:

The equipment consists of components such as a motor, wear-resistant pump, mortar concentrator, linear dewatering screen cleaning tank, and reaction box. Mud water flows into the cleaning tank and is sent to the concentrator through a wear-resistant pump. The concentrator separates sewage and sand, and the sand is sent to the dewatering screen through the nozzle. After dewatering, it is sent to the conveyor belt. The sewage returns to the reaction tank and is diverted into the cleaning tank, with the excess part leaking out.

Features and advantages:

1. This fine sand recovery device can effectively reduce the loss of fine sand, keeping it within 5-10%. Effectively solved the problem of high fineness modulus of finished sand and low stone powder content in manual material processing systems.

2. Dehydration screens, sieve plates, and nozzles are newly developed synthetic plastics that have a wear life 5-6 times longer than steel plates and are less prone to clogging.

3. The fine sand recovery system can recover up to 90% of the fine particulate materials in the total emissions, which has unparalleled technological and economic advantages compared to other equipment.

4. The fine particles are fully recovered, reducing the workload of the sedimentation tank and lowering the cleaning cost of the sedimentation tank;

5. The fine sand recycling system reduces the natural stacking time of fine materials and can be directly transported to supply the market.

6. It can be designed, modified, and applied to more fields according to different user requirements.
