Description

Technical Field

[0001] The utility model relates to the field of sludge dredging, and more specifically, to a sludge processing device for dredging engineering. Background Art

[0002] Desilting is one of the most commonly used engineering measures in water conservancy projects. When desilting, personnel of water conservancy project facilities generally use suction pumps to suck out the silt on the bottom of the water, and then transport the sucked silt to other places for storage by engineering vehicles. However, due to the high water content, high clay content and low strength of the silt obtained by suction, the water in the silt is easily spilled onto the road during transportation, seriously polluting the road environment and affecting the lives of surrounding residents. Therefore, it is necessary to solidify the silt before transportation, so as to facilitate storage, transportation and reuse.

[0003] Existing devices for dehydrating sludge, such as a dredging device for clearing river sludge in Application No. 201711387831.9, can separate the sludge from water in time through a sludge storage tank and a push plate. The hydraulic cylinder pushes the push plate to squeeze the sludge, which can quickly separate the sludge from water. However, the squeezed sludge remains in the sludge storage tank, which is inconvenient to discharge, which affects the subsequent squeezing of sludge. Utility Model Content
