Sloping-plate sedimentation equipment

Abstract

The invention relates to sloping-plate sedimentation equipment. After a sloping-plate sedimentation tank and a sloping-plate sedimentation tank with a small interval run for a certain period of time or when water quality and water amount change in a sedimentation process applied to water treatment, sedimentation efficiency and the water quality of drained water fall remarkably, severe sludge accumulation and blockage between a sloping pipe and a sloping plate are led and even the sloping pipe and the sloping plate are crushed by pressure. The equipment comprises a sedimentation tank (1), wherein a group of Y-shaped sloping plates (6) are connected to the sedimentation tank; the sloping plates are connected with one another through connecting ribs (7); the included angle between each sloping plate and the horizontal plane is 60 degrees; a water collecting groove (3) is formed on the sedimentation tank; a water outlet pipe (4) is arranged at the tail end of the water collecting groove; and a sludge discharge pipe (2) and a sedimentation sludge bucket (5) are arranged below the sedimentation tank. The product is used in the field of water treatment and chemical industry.

Description

technical field [0001] The invention relates to a settling equipment with large spacing slanting plates applied to the water treatment process. Background technique [0002] At present, the sedimentation process forms used in water treatment mainly include advection tanks, small-space inclined plates, and inclined tube sedimentation tanks. Among them, the inclined plate with small spacing and the inclined tube sedimentation tank fully embody the advantages of the shallow tank, and the sedimentation efficiency is very high, but the smaller the distance between the inclined plates, the higher the sedimentation efficiency. However, in this year's practical application, after the inclined plate sedimentation tank and the inclined plate sedimentation tank with small spacing have been in operation for a period of time, or when the water quality and quantity change, the sedimentation efficiency and effluent water quality will drop significantly, resulting in serious problems betwee...

AI Technical Summary

Problems solved by technology

However, in this year's practical application, after the inclined plate sedimentation tank and the inclined plate sedimentation tank with small spacing have been in operation for a period of time, or when the water quality and quantity change, the sedimentation efficiency and effluent water quality will drop significantly, resulting in serious problems between the inclined tube and the inclined plate. Mud accumulation and blockage, even collapsed inclined pipes and inclined plates

Therefore, many water plants use advection pools that occupy a large area and have low efficiency, but are quite stable in operation.

The main reason for the above problems is that for the inclined tube sedimentation tank, its hexagonal structure is not conducive to mud discharge.

For inclined plate sedimentation tanks, since the smaller the spacing, the higher the sedimentation efficiency, it is often used in inclined plate sedimentation tanks with smaller spacing, but when the spacing of the inclined plates is reduced, the mud discharge will not be smooth, which will lead to Mud and blockage
