Inclined plate sedimentation device and sedimentation tank

Abstract

The invention relates to the technical field of water treatment, in particular to an inclined plate sedimentation device and a sedimentation tank constructed thereby. The inclined plate sedimentation device comprises a plurality of inclined plate sedimentation units arranged in parallel; each inclined plate sedimentation unit comprises a mud sliding plate, an inlet water baffle and an outlet water baffle; the inlet water baffle and the outlet water baffle extend in the normal direction from a mud sliding surface and are encircled with the mud sliding surface to form a mud sliding channel; a mud discharge port of the mud sliding channel is positioned in a settlement channel at the side part of the inclined plate sedimentation device or at the bottom of the inclined plate sedimentation device; a gap among the inlet water baffle, the outlet water baffle and the adjacent mud sliding plate forms a water through channel; a mudguard vertically extending downwards from the lower end is arranged at the lower end of the mud sliding plate positioned at the mud discharge port in the settlement channel. The inclined plate sedimentation device is low in material consumption and convenient to manufacture, and the water purifying effect is effectively improved.

Description

technical field [0001] The invention relates to a water treatment device, in particular to an inclined plate settling device and a settling tank constructed with the inclined plate settling device. Background technique [0002] The patent document with the publication number CN103495292A discloses a horizontal split-flow inclined plate purification device and a settling tank with the purification device. The purification device includes multiple sets of sedimentation units. The sedimentation unit is composed of a deflector, a first baffle, a second baffle and a plurality of obliquely arranged wing plates; the wing plates are arranged along the water flow direction, and the first baffle and the second baffle are The second baffle is arranged on the front and rear sides of the deflector; the inlet end of the wing plate is connected to the first baffle plate, and the outlet end is connected to the second baffle plate, and the wing plate is divided into sedimentation units along...

AI Technical Summary

Problems solved by technology

[0003] The sloping plate purification device has a complex structure, which is inconvenient to manufacture and assemble, resulting in high manufacturing costs; the sediment deposited on the second wing plate is easily taken out of the device by the water flow from the water outlet of the device, resulting in an increase in the turbidity of the water flow , which reduces the purification effect of the water flow; the sediment that slides into the channel from the first wing part is easily moved horizontally and taken away by the water flow below, which leads to a further increase in the turbidity of the water flow and further reduces the purification effect of the water flow; because each sediment A large number of flaps are set in the unit, resulting in the occupation of the water passing area of ​​the flow channel
