Description

Technical Field

[0001] This utility model relates to the field of sludge solidification technology, specifically to a sludge solidification pretreatment device. Background Technology

[0002] In industrial and agricultural production processes, such as at the bottom of fishponds and lakes, a large amount of silt is generated and accumulated. If this silt is processed, filtered, and solidified, it can be transformed from waste into treasure. The reprocessed and solidified silt can not only be used for planting grass and flowers, but also for building roadbeds and slopes. However, when transporting the silt, a large amount of water is retained in it. Therefore, the drying process of the silt requires a long time to dry the internal moisture, which increases the energy consumption of the entire device and is not conducive to energy conservation and environmental protection.

[0003] In view of this, there is an urgent need to design a sludge solidification pretreatment device. The sludge is fed into the dewatering pretreatment device, a solidifying agent is added, and centrifugal force is used to initially remove the water from the sludge. The drive cover drives the centrifuge cylinder to rotate, and the rotating guard drives the outer cylinder of the centrifuge to rotate, ensuring smooth dewatering and discharge of the sludge.
