Anti-blocking inclined plate sedimentation basin

Abstract

The invention provides an anti-blocking inclined plate sedimentation basin. After the inclined plate sedimentation basin is operated for a period of time, mud is seriously deposited between an inclined pipe and the inclined plates to cause blocking, even the inclined pipe and the inclined plate are crushed. The anti-blocking inclined plate sedimentation basin comprises a sedimentation basin body (1); the sedimentation basin body is connected with one group of the inclined plates (3) through connecting ribs (2) which are transversely and vertically crossed; a water collecting groove (4) is arranged above the sedimentation basin body and a water outlet pipe (5) is mounted at the tail end of the water collecting groove; sedimentation mud buckets (6) and mud discharging pipes (7) are mounted below the sedimentation basin body; the inclined plates are formed by three sections; the included angle between the inclined plate at the upper section and the horizontal plane is 45-50 degrees; the included angle between the inclined plate at the middle section and the horizontal plane is 50-60 degrees; and the included angle between the inclined plate at the lower section and the horizontal plane is 60-70 degrees. The anti-blocking inclined plate sedimentation basin disclosed by the invention is used for the fields of water treatment, chemical engineering or wet-method metallurgy and the like.

Description

technical field [0001] The invention relates to a chemical equipment, in particular to an anti-blocking inclined plate sedimentation tank. Background technique [0002] A sedimentation tank is a structure that uses sedimentation to remove suspended solids in water. Sedimentation tanks are widely used in wastewater treatment. It has many types, which can be divided into three types: advection type, vertical flow type and radial flow type according to the direction of water flow in the pool. The advection sedimentation tank consists of three parts: the inlet and outlet, the water flow part and the sludge bucket. The advection sedimentation tank has simple structure, good sedimentation effect, stable working performance and wide use, but it occupies a large area. The plane of the vertical flow sedimentation tank is circular or square. The waste water is discharged into the pool from top to bottom through the water inlet pipe in the center of the sedimentation tank, and ...

AI Technical Summary

Problems solved by technology

However, in practical applications, after the inclined plate sedimentation tank and the inclined plate sedimentation tank with small spacing have been operated 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 mud accumulation between the inclined pipe and the inclined plate. With clogging, 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
