Abstract

The utility model relates to a water collection tank of a primary sedimentation pool and a secondary sedimentation pool for water treatment, in particular to an anti-floating device of the water collection tank; a separator is arranged between the sedimentation pool and the water collection tank; brackets are fixed on both surfaces of the separator; a buoy is hinged with a bracket; the bracket on the other surface can be hinged with a flap door used for closing a water outlet tank; the lower end of the flap door is movably connected with the buoy through a connecting rod. When water flows in the sedimentation pool, the water collection tank is provided with a water outlet; the flap door is controlled to be open and close through the buoy, so as to reduce the buoyancy on the water collection tank applied by the water in the pool and reduce the acting force on the support separator of the water collection tank applied by the water in pool; meanwhile, the structural requirement of the separator is reduced; the civil construction cost is reduced, and the water quality of the effluent water is greatly improved.

Description

The water leg anti-floating system

One, technical field

The utility model relates to the water leg of water treatment with primary sedimentation pond and secondary sedimentation tank, particularly water leg anti-floating system.

Two, background technology

At present, the water treatment field structures that have water leg commonly used, as circle or rectangle primary sedimentation pond and secondary sedimentation tank, water leg is installed on the sedimentation basin brace summer, and the water in the pond enters in the water leg by overflow.

Pond water could flow in the water leg after must reaching the water leg flood level, during the water inlet of empty pond, pond, at the bottom of water level reaches water leg and rise to gradually that water leg bears huge buoyancy in the process of flood level; During pond water emptying, the pool inner water position descends rapidly, but the water in the water leg can not descend simultaneously, and water leg bears huge hydraulic pressure.

Higher to the water leg requirement of strength when manufacturing and designing like this, and higher to sedimentation basin supporting construction requirement of strength, connect and want reliable, the time regular meeting phenomenons such as water leg come-up, torsional deformation take place.Be generally and be convenient to Inlet and outlet water, perforate at interval at the bottom of water leg, but at the bottom of the pond, easily form spring one by one, a large amount of suspensions are gone out from the hole with current, influence effluent quality.

Three, summary of the invention

The purpose of this utility model is at above-mentioned the problems of the prior art, and a kind of anti-floating system that can regulate the water leg water level according to SEA LEVEL VARIATION inside and outside the water leg automatically is provided.

In order to reach described purpose, the invention provides a kind of partition that between sedimentation basin and water leg, has, be fixed with support at partition two faces, there are a floating drum and a support hinged, the another side support is hinged with the flap valve that can seal effluent trough, the lower end of flap valve links to each other with floating drum (1), flexibly connects by connecting rod.

Beneficial effect is, in the pond during Inlet and outlet water, water leg has a delivery port, open and close by floating drum control flap valve, can effectively reduce Chi Shui to water leg buoyancy, reduce water leg is supported the active force that cuts off, reduce the structural requirement that cuts off, reduce the civil engineering construction cost, also significantly improved effluent quality.

Four, description of drawings

Fig. 1 is the utility model water leg anti-floating system structural representation.

Among the figure: 1. floating drum, 2. connecting rod, 3. flap valve, 4. seal

Five, the specific embodiment

Below in conjunction with accompanying drawing, the utility model specific embodiment is described in further detail:

Between primary sedimentation pond or secondary sedimentation tank and water leg, a partition is arranged among Fig. 1, be fixed with support at partition two faces, there are a floating drum (1) and a support hinged, floating drum (1) can rotate around support, the another side support is hinged with the flap valve that can seal effluent trough, the lower end of flap valve links to each other with floating drum (1), flexibly connects by connecting rod.

When intaking in the pond, under the deadweight effect of floating drum (1), by connecting rod (2) flap valve (3) is opened effluent trough, make the effluent trough water inlet, when the pool inner water position arrives certain altitude, floating drum moves on the floating drum under the water buoyancy, drives flap valve by connecting rod and progressively closes effluent trough, up to the complete closed effluent trough of flap valve, when intaking in the pond, effluent trough is in into water state, can effectively reduce water leg buoyancy to supporting the active force that cuts off.

When need blow-down pit water, along with the decline of pool inner water position, the floating drum loss of buoyance is opened flap valve under the deadweight effect, and the interior water of effluent trough can be discharged, and reduces the active force to cutting off.

Reduce the structural requirement that cuts off, reduced the civil engineering construction cost, also significantly improved effluent quality.
