Description

A new type of two-way flow inclined plate sedimentation tank

Technical field

The utility model relates to an inclined plate sedimentation tank.

Background technique

At present, the main sedimentation tanks include advection sedimentation tanks and inclined plate (inclined tube) sedimentation tanks. The advection sedimentation tank is a traditional design process, which is generally used in large and medium-sized water purification plants. It has the advantages of low cost, convenient operation and management, and strong adaptability to raw water, but it occupies a large area and difficult to operate and manage sludge. The sedimentation devices placed in the inclined plate (inclined tube) sedimentation tank are mainly the same direction flow inclined plate (inclined tube) with different spacing, and the upward flow inclined plate (inclined tube). Compared with the traditional advection sedimentation tank, this kind of sedimentation tank has the characteristics of high sedimentation efficiency and small footprint, but its adaptability to water quality is worse than that of the advection sedimentation tank. The mud discharge effect of the commonly used perforated mud discharge pipe is unstable. When the turbidity of the raw water is high, the mud discharge effect is poor; it is troublesome to maintain and manage when installing mechanical sludge discharge equipment, the moisture content of the sludge discharge is high, and the water consumption of the water plant increases.

Contents of the invention

The purpose of this utility model is to provide a new type of two-way inclined plate sedimentation tank to increase the effective sedimentation of the sedimentation tank in order to overcome the fact that the existing two sedimentation tanks cannot meet the requirements of small footprint, strong adaptability to water quality, and good mud discharge effect at the same time. area, improve sedimentation efficiency, smooth mud discharge, reduce land occupation, and reduce civil construction investment.

The technical solution adopted by the utility model for achieving the above purpose is: a two-way flow inclined plate settling device is set in the sedimentation tank, and the device is a multi-layer folding inclined plate unit closely connected with two Orientation slide type mud deflector unit.

The multi-layer foldable slant plate unit is a single foldable slant plate, which is assembled according to the same central axis and the same distance in the vertical direction.

The distance between the double-layer folding inclined plates is 20-150mm.

The slide type mud deflector unit is formed by combining a single mud deflector with a certain angle with the horizontal direction.

Water distribution flower walls are set at the inlet and outlet ends of the sedimentation tank.

The bottom of the two-way inclined plate settling device is provided with a gravity mud discharge bucket.

The gravity mud discharge hopper is connected to the main mud discharge pipe, and an electric mud discharge valve is installed on the main mud discharge pipe.

Compared with similar products, the utility model has remarkable features: a new type of two-way flow inclined plate (composed of a multi-layer folding inclined plate unit module and two inclined slide type mud guide unit modules) is arranged in the sedimentation tank, and the water outlet It is divided into two independent areas with sedimentation, the flow direction of water outlet and mud discharge are different, and water outlet and mud discharge do not interfere with each other; the effective sedimentation area of the sedimentation tank is increased, the sedimentation efficiency is improved, the land occupation is reduced, and the civil construction investment is reduced; the water outlet and mud discharge process are independent , the mud discharge time increases, the water content of the sediment increases, and the water consumption of the plant area is reduced; the water inlet and outlet areas of the sedimentation tank are equipped with perforated flower walls corresponding to the two-way flow inclined plate sedimentation device, and the triangular area at the bottom of the inclined plate of the multi-layer folding inclined plate unit and the slide type mud deflector unit are not connected to water. The bottom of the sedimentation tank adopts a gravity mud discharge bucket. According to the hydraulic characteristics, multiple buckets share a single mud discharge pipe to discharge evenly without clogging. Each main pipe is equipped with an electric mud discharge valve, which can be quickly opened to discharge mud, realizing remote and on-site control of mud discharge, smooth mud discharge, and simple maintenance.

Detailed ways:

The new two-way flow inclined plate sedimentation tank as shown in Figure 1, the two-way flow inclined plate sedimentation device is set in the pool, as shown in Figure 3, the two sides of the multi-layer folded inclined plate unit 1 are closely connected with a wall different from the inclined direction of the folded inclined plate Slide type mud deflector unit 2. The multi-layer folding sloping plate unit is composed of single folded sloping plates in the vertical direction according to the same central axis and the same spacing to form a multi-layer folding sloping plate unit. The slide type mud deflector is composed of a single piece of mud deflector according to a certain inclined direction. The bottom of the sedimentation tank with two-way swash plate is equipped with a gravity mud discharge bucket 3, and the gravity mud discharge bucket is connected to a row of mud main pipes, and an electric mud discharge valve 5 is installed on each mud discharge main pipe 4; the water inflow and outflow of the sedimentation tank The water distribution flower wall 6 shown in Figure 2 is set at the end.

When working, the water flow enters the folding sloping plate of the two-way flow sloping plate sedimentation device through the water distribution wall, and the mud-water separation is completed in the sloping plate, and the sediment slides down through the inclined slide type mud guide plate to the bottom gravity mud discharge bucket, and then through the electric mud discharge The valve is quickly opened to discharge mud, and the outlet water flows out evenly through the other side of the spray wall.
