Abstract

Disclosed is a co-flowing direction inclined plate precipitator which is characterized in that an inclined plate 1 is shaped like a bended plate; the wetted cross section is V-shaped; a water collecting device 2 is a perforated pipe which is in correspondence with the horizontal projection of the water flowing direction which is between the water collecting device and the inclined plate; the sludge-water separating condition is improved after the co-flowing direction inclined plate precipitator is used, improving the sedimentation effect; meanwhile, the utility model has convenient installation, low cost, stable and reliable running. The utility model is applicable to the potential-digging revamping of the new sedimentation tank and the old tanks.

Description

A kind of same flow oblique board sedimentation device

The utility model belongs to a kind of filler in the water supply and drainage structure (or equipment).

At present both at home and abroad the same flow oblique board sedimentation utensil that adopts in the precipitation structures (or equipment) of water purification, sewage treatment plant has the deposition efficiency advantages of higher, but also exist collecting system make difficulty, cost high, turn over the muddy problem such as effluent quality that influences easily.

The purpose of this utility model is exactly that a kind of novel same flow oblique board sedimentation device will be provided, and with further raising deposition efficiency, reduces cost of manufacture.

The utility model is by bias plate, collector pipe, form with three parts such as framework.Main points of the present utility model are: swash plate is a flap-like, and the cross-section of river is a V-arrangement, captation for be located at the bottom and with the bias plate in the corresponding to perforation collector pipe of floor projection of water (flow) direction.

The utility model compared with prior art, it has the deposition efficiency height, captation is simple for production, effluent quality good, reliable, characteristics such as cost is low.

Below in conjunction with drawings and Examples the utility model is further described:

Fig. 1 is the flat sectional drawing of same flow oblique board sedimentation device.

Fig. 2 is the 1-1 profile of Fig. 1.

Fig. 3 is the 2-2 side view of Fig. 1.

As seen from the figure, the same flow oblique board sedimentation device is made up of bias plate 1, collector pipe 2, framework 3.Bias plate 1 is to be formed by the skewed setting of the parallel flap of multilayer, and tiltedly length direction divides the inclination angle different two sections, bias plate epimere and horizontal plane angle α ₁=35～55 degree, the hypomere inclination alpha ₂=55～65 degree, the knuckle β of flap=70～120 degree, flanging width A=50～200 millimeters, flap beam overall B=500～2000 millimeters, the oblique long epimere of bias plate is L ₁=1000～2000 millimeters, hypomere L ₂=100～300 millimeters, bifoldable plate spacing C=15～80 millimeters.Collector pipe 2 is many perforated pipes, is located at the bottom of each drift angle of flap respectively, all establishes gully-hole between two swash plates, single or double layout, and its caliber and aperture are determined according to flow.Framework 3 is the outer gimbal supports that form same flow oblique board sedimentation device assembly with fixing bias plate and collector pipe.Source water enters sedimentation basin through adding after alum mixes cohesion, the V-arrangement settling zone that enters between the bias plate suitable for reading from the same flow oblique board sedimentation device, oblique from top to bottom slowly mobile, aggressiveness particle in the water is by being precipitated to the bottom surface, accumulate to when a certain amount of and then slide to bias plate base angle, slide to bias plate hypomere again along the slope, base angle and discharge settling vessel along bias plate face.The clear water of post precipitation is then drawn by the perforation collector pipe.Because the distance with the clear water collector pipe, is drawn back in the effect of flap, precipitation body refuse to the separation of the base angle of V-shaped groove, having avoided body refuse to rise influences effluent quality, has improved the efficient of mud-water separation greatly.

Claims

1. a same flow oblique board sedimentation device of mainly being made up of bias plate 1, collector pipe 2, framework 3 etc. is characterized in that said bias plate is to be formed by the skewed setting of the parallel flap of multilayer, and tiltedly length direction divides the inclination angle different two sections.

2. according to the described same flow oblique board sedimentation device of claim [1], it is characterized in that: collector pipe (2) is many perforation collector pipes, is located at the bottom of bias plate 1 each corner angle staff respectively, and the collector pipe center line is consistent with the floor projection line of water (flow) direction in the bias plate.
