Inverted V-shaped plate sedimentation device

Abstract

The invention discloses an inverted V-shaped plate sedimentation device which is a device for sedimentating and separating solid particles in liquid. The inverted V-shaped plate sedimentation device consists of a water basin, and inverted V-shaped plates, sealing plates, edge beams, ridges, ridge brackets, a sludge discharging pipe, a water inlet pipe, a water outlet pipe and the like which are arranged in the water basin, wherein a plurality of layers of horizontally stacked inverted V-shaped plates are adopted; liquid flows among the inverted V-shaped plates; the solid particles are sedimentated on the surfaces of the inverted V-shaped plates and downwards slide laterally so as to realize solid-liquid separation; the liquid horizontally flows along the longitudinal direction, and the sedimentated solid particles downwards slide transversely and stay in sludge sedimentation channels for sedimentation; the solid particles and the sludge sedimentation channels are not interfered, so that the sedimentation effect is good; water inlet and outlet buffering regions are greatly reduced; the volume utilization efficiency of the basin body is high, and the water basin is small in size; the inverted V-shaped plates are simple in structure; the number of stacking layers can be randomly adjusted, and the inverted V-shaped plates are easily connected with front and back buildings.

Description

technical field [0001] The invention relates to a device for precipitating and separating solid particles in liquid, in particular to an inverted V-shaped plate sedimentation and separation device, which adopts multiple layers of inverted V-shaped plates stacked horizontally, and the liquid flows through the layers of the inverted V-shaped plate , solid particles are deposited on the surface of the inverted V-shaped plate to realize solid-liquid separation, which belongs to the field of solid-liquid separation technology, and is suitable for the precipitation and separation of solid particles with a density greater than liquid in water treatment, chemical engineering and other treatment processes. Background technique [0002] In tap water treatment and sewage treatment projects, the sedimentation method is used to remove impurity particles with a density greater than that of water. In chemical engineering, precipitation is also used to separate particles from liquids. The ...

Problems solved by technology

There are three disadvantages in the inclined tube sedimentation tank. First, the water and the sludge interfere with each other, which affects the sedimentation effect. The water enters the inclined tube from the bottom up, and the sludge slides downward from the inclined tube. The two collide together and partially settle The mud is washed up by the incoming water and then enters the water, which increases the sedimentation load; second, the height of the tank body is large, and it is not easy to connect w
