Sludge collecting device for sludge solidification treatment and sludge solidification treatment method

Abstract

The invention discloses a sludge collecting device for sludge solidification treatment, and relates to the technical field of sludge solidification treatment. The sludge collecting device comprises a sludge pumping box, an inner storage cavity is formed in the sludge pumping box, an extrusion mechanism is arranged in the inner storage cavity, a sludge pumping mechanism is arranged at one side of the sludge pumping box, and a first electric telescopic rod is installed at one side of the inner wall of the sludge pumping box; and a pushing plate is installed at the output end of the first electric telescopic rod, a lower through hole is formed in the bottom of the sludge pumping box, two water filtering plates are embedded in the lower through hole, and a sealing mechanism is arranged at the side, away from the first electric telescopic rod, of the inner wall of the sludge pumping box. Thesludge collecting device has the effect that the pumping mechanism is used for pumping sludge located on a riverbed into the conveying box, an extrusion plate is used for conducting preliminary extrusion on the sludge, the water content in the sludge can be effectively reduced, water can be drained through the water filtering plate, and preliminary drying in the later period is facilitated.

Description

technical field [0001] The invention relates to the technical field of sludge solidification treatment, in particular to a sludge collection device for sludge solidification treatment and a sludge solidification treatment method. Background technique [0002] Silt is deposited in still water or slow flowing water environment, formed by physical, chemical and biochemical actions, unconsolidated soft fine-grained or very fine-grained soil, which belongs to modern recent sediments, and the composition of silt can be silty according to its particle size Or clay, fine sandy or very fine sandy very few, the clay minerals of coastal silt are mainly illite and montmorillonite, freshwater silt is mainly illite and kaolinite, and the silt in the riverbed is too Most of the time, sludge needs to be treated to avoid floods caused by river bed elevation. Sludge treatment is the process of treating, solidifying, dehydrating, stabilizing, drying or incinerating sludge. At present, when sol...

[0002] Silt is deposited in still water or slow flowing water environment, formed by physical, chemical and biochemical actions, unconsolidated soft fine-grained or very fine-grained soil, which belongs to modern recent sediments, and the composition of silt can be silty according to its particle size Or clay, fine sandy or very fine sandy very few, the clay minerals of coastal silt are mainly illite and montmorillonite, freshwater silt is mainly illite and kaolinite, and the silt in the riverbed is too Most of the time, sludge needs to be treated to avoid floods caused by river bed elevation. Sludge treatment is the process of treating, solidifying, dehydrating, stabilizing, drying or incinerating sludge. At present, when solidifying sludge Generally, the drying method is used, but it takes a long time to solidify the sludge by using the drying method, which greatly reduces the speed of sludge treatment and is inconvenient to use. At present, after the sludge is extracted from the river bed, it is only a simple process. Filtering water, there will still be more water in the sludge, which is inconvenient for subsequent sludge solidification treatment
