Description

Technical Field

[0002] Shield excavation waste is the soil excavated from the ground by the shield machine during shield tunneling. During tunneling, the shield machine cuts through the soil and discharges the waste through the soil chamber and screw conveyor. However, when the shield machine excavates into the aquifer, the soil and water mix to form a slurry due to the large amount of water in the soil. This slurry is difficult to transport due to its high water content and does not meet environmental standards. Therefore, the resulting slurry needs to be treated to reduce its water content for subsequent transportation.

[0003] For the dehydration treatment of slag slurry, the existing authorization announcement number CN219486667U proposes a dehydration device for slag processing, which includes a device shell and a dehydration area opened in the device shell. The device uses an extrusion method to process the slag slurry, and uses an extrusion method to extrude the slag slurry one by one and form mud blocks for easy transportation.

Since it is necessary to stop and wait when unloading and loading the slag slurry, it is impossible to achieve continuous processing of the slag slurry, and the working efficiency is low. To address the above problems, we provide a filter press mechanism for shield slag processing. Utility Model Content
