Description

Technical Field

[0001] The present application relates to the field of filter press equipment, and in particular to a split concentrating plate-and-frame filter press and a lake reservoir sludge dewatering process. Background Art

[0002] As vital components of natural water systems, lakes and reservoirs play a crucial role in regulating water levels, draining floodwaters, providing water resources, and maintaining ecological balance. However, over time, lakes and reservoirs accumulate sediment, reducing their storage capacity and degrading water quality. To improve water quality and restore the ecological environment, desilting and remediation efforts are necessary.

[0003] At present, filter presses are often used in the sludge treatment process during the dredging and remediation of lakes and reservoirs. Plate and frame filter presses are intermittent filtration equipment for separating solids and liquids in suspensions.

[0004] The existing filter press is an advanced separation machine integrating mechanical, electrical, and hydraulic functions. It consists of a frame, filter plates, and a plate-pulling trolley. The frame supports several filter plates, and the plate-pulling trolley is mounted on the frame and drives the filter plates to slide along the frame. During use, the filter plates separate the suspended liquid into solids and liquids, leaving the filtered solids between the two filter plates. The solids then condense into a mud cake. When filtration is complete, the plate-pulling trolley moves to the filter plates, driving them to slide within the frame, separating the two adjacent filter plates. This allows the mud cake between the two plates to fall under the action of gravity, completing the unloading of the filter press.

[0005] The above-mentioned existing technical solutions have the following defects: in actual use, since pressure is applied to the mud cake during the filtration process, the mud cake is tightly adhered to part of the filter press plate, so manual tools are required to assist in unloading the material next to the filter press, resulting in low mud cake unloading efficiency of the filter press.
