Intelligent screening device for dredging bottom mud

Abstract

The invention discloses an intelligent screening device for dredging bottom mud. The intelligent screening device comprises a controller (1), a water conveying pipe (2), a flow dividing and mixing layer (3), a muddy water adjusting tank (5), an inductor (6) and a multi-layer screening assembly. The controller is electrically connected with an inductor arranged in the muddy water adjusting tank, one end of the water conveying pipe is externally connected with a water source, the other end is connected to the flow dividing and mixing layer, water is conveyed into the flow dividing and mixing layer, and a flow speed control valve on the water conveying pipe is connected with the controller; the flow dividing and mixing layer is arranged above the muddy water adjusting tank, and a plurality offlow dividing gaps (31) are formed in the flow dividing and mixing layer at intervals, so that muddy water flows into the muddy water adjusting tank through the flow dividing gaps; a muddy water adjusting tank water outlet (51) is formed in the muddy water adjusting tank, a water inlet of the multi-layer screening assembly is connected below the muddy water adjusting tank water outlet, and the water outlet of the multi-layer screening assembly is connected to a sedimentation tank. Impurities with different sizes can be separated, and the concentration of bottom mud is adjusted, so that the concentration of muddy water entering the sedimentation tank is automatically controlled.

Description

technical field [0001] The invention relates to sludge treatment equipment for environmental engineering, in particular to an intelligent screening device for dredging bottom sludge. Background technique [0002] River sediment is one of the important factors affecting the river environment, and the treatment and disposal of river sediment has always been a difficult problem in river management. Usually, treatment plants are set up along the river or near the river for the treatment of river sediment , but due to the different hydrological conditions in various places, it is difficult to set up treatment plants nearby for small rivers, and the cost is high. deal with. For this kind of sediment, due to the complex surrounding environment of each river channel, the types and sizes of impurities that may be contained are different, and the concentration of the sediment is also inconsistent, so the treatment is difficult. Contents of the invention [0003] The object of the ...
