Combined type solid-liquid separation device

Abstract

The invention discloses a combined type solid-liquid separation device, which comprises a slurry feed valve, a stander, an eccentric vibration residue filter, a storage sedimentation bin, a vertical screw conveyer, a reducing screw squeezing machine and a control system, wherein the wall of the storage sedimentation bin is provided with a clear solution discharge valve and a suspension discharge valve, the clear solution discharge valve is positioned above the suspension discharge valve, the stander is positioned on the lateral surface of the storage sedimentation bin, the eccentric vibrationresidue filter is slantwise arranged on the stander, the slurry feed valve is communicated with the eccentric vibration residue filter, the eccentric vibration residue filter is communicated with thestorage sedimentation bin, the vertical screw conveyer is positioned in the center of the storage sedimentation bin, and the discharge end of the vertical screw conveyer faces to the bottom end of the storage sedimentation bin; and the reducing screw squeezing machine is slantwise arranged below the storage sedimentation bin transversely and is communicated with the bottom end of the storage sedimentation bin. The combined type solid-liquid separation device has the advantages of reasonable structure, stable equipment operation and good solid-liquid separation effect, and can quickly separateand treat various slurries containing residues with different specific gravities, different shapes and different sizes.

Description

technical field [0001] The invention relates to a solid-liquid separation device, in particular to a composite solid-liquid separation device suitable for solid-liquid separation containing many impurities with different specific gravity, different shapes and different sizes, mainly used for dredging rivers and lakes by twisting suction The mud that comes out is subjected to an initial rapid solid-liquid separation. Background technique [0002] The applicant disclosed a solid-liquid separation tower in Chinese patent application 200810215084.5 "Sinking Composite Solid-liquid Separation Tower", which includes a storage bin, a mud feed valve, a clear liquid discharge valve, a suspension discharge valve, Vertical conveyors, drive bridges, variable diameter screw presses, bases and control systems. The solid-liquid separation tower achieves rapid and ideal solid-liquid separation of the initial fluid mud through natural sedimentation of mud, sediment transported by a vertical ...

Problems solved by technology

However, due to the extremely complex composition of the mud, although its basic ingredients are water and mud, it is mixed with various objects of different specific gravity, different shapes, different sizes and materials, such as rotten wood, tree roots, iron rods, iron wires, plastic sheets or Plastic bags, nylon ropes and other miscellaneous residues have different sedimentation speeds, and they will be at different liquid levels and levels, so they will block or even block the corresponding equipment at different liquid and slag discharge ports. And then cause the destruction and paralysis of the whole separation system

For example, although a long iron rod will settle to the bottom of the separation tower and be drawn into the variable-diameter screw squeezer, once the iron rod is too long, it will be stuck in the variable-diameter screw squeezer; If the roots soaked in water will float in the thin mud, they will be discharged from the sinking and squeezing compound solid-liquid separation tower through the suspension discharge valve, and will be sucked into the subsequent configuration of the decanter centrifuge, which will cause the decanter centrifuge to be stuck and Immediately there will be a strong eccentric vibration, which will eventually lead to equipment damage; the lightest wood chips, branches, river grass, etc. will cause the blockage of the clearing liquid valve, or get stuck in the gate valve, resulting in poor operation of the entire separation equipment
