Abstract

The utility model belongs to the environmental protection equipment and specifically is a device discharging the supernatant water of clarified sewage. The present decanter consists of a buoy, an expansion pipe, a drainage pipe and an electromagnetic valve and is characterized in that the electromagnetic valve is positioned on the drainage pipe outside a sewage tank and the buoy is connected with a scum isolation box by a pipeline. The drainage scum isolation box with a water inlet at the lower part has a weir inside. The mouth of the weir is higher than the water surface. The utility model has a simple structure, a convenient maintenance and a long serve life, needs no power and disturbs no sediment during water discharging.

Description

Hydrophone is strained in unpowered external control

" technical field "

The utility model belongs to environmental protection equipment, the device that the sewage supernatant after particularly will clarifying is discharged.

" technical background "

Strain hydrophone and be a kind of supernatant in the cesspool is drained and the device of the water-bed precipitating sludge of not disturbance.The hydrophone of straining of introducing Australian technology preparation is to adopt driven by motor cantilevered draining weir, thereby from top to down is discharged the clear water on top layer, though this kind equipment stable water outlet, the heavy mud that is difficult for the disturbance bottom, but mechanical driving part Chang Yushui contact is out of order easily, the maintenance trouble, power consumption is big, the equipment price height; The another kind of hydrophone (99245559.6) of straining adopts floating drum directly to connect delivery port, be provided with air inlet magnetic valve and exhaust solenoid valve between draining weir and drainpipe, what rely on is that the floating drum deadweight that pours into water sinks to draining, though this hydrophone power consumption of straining reduces, but electrical equipment moisture-sensitive, maintenance difficult, and when aeration, have part mud and enter in the draining weir.

" summary of the invention "

Technical problem to be solved in the utility model provides a kind of unpowered external control and strains hydrophone, and its apparatus structure is simple, and is easy to maintenance, and draining does not need power, and mud, long service life are hanged down in not disturbance.

Solving the scheme that technical problem of the present utility model adopts is: existing by straining on the hydrophone basis that floating drum, drainpipe, telescoping tube and magnetic valve are formed, magnetic valve is loaded on the outer drainpipe of cesspool, the water district that on floating drum, connects the scum silica frost shielded box with pipeline, the water inlet of scum silica frost shielded box is in the underwater and the draining weir wherein is housed, and the draining crest of weir is higher than the water surface.

When aeration, although low mud rises in the cesspool, because the draining crest of weir is higher than the water surface, mud can only enter the water inlet of scum silica frost shielded box, by draining weir retaining outside the water district, treat that aeration finishes after, mud can arrive at the bottom of the pond again in natural sedimentation, and the floating scum silica frost of the water surface is blocked in outside the scum silica frost shielded box.When draining, open external magnetic valve, in floating drum, produce negative pressure, the non-surperficial upper strata clear water of Chi Shui is subjected to siphonage, and clear water enters from water inlet, climbs over the draining crest of weir again, flow into floating drum, flow out through telescoping tube, the water surface scum silica frost is but blocked by the outer wall of scum silica frost shielded box; During closed electromagnetic valve, draining stops, and it is contour with the pond water water surface that the water level at draining crest of weir place recovers, and can carry out the circulation of next aeration again.

" description of drawings "

Fig. 1 is a structural representation of the present utility model.

Each label is represented successively among the figure: floating drum 1, drainpipe 2, telescoping tube 3, magnetic valve 4, pipeline 5, scum silica frost shielded box 6, water district 7, water inlet 8, draining weir 9, the water surface 10, buoyancy adjustment mouth 11, cesspool 12.

" specific embodiment "

Referring to accompanying drawing, this device is the improvement of being made up of floating drum 1, drainpipe 2, telescoping tube 3 and magnetic valve 4 existing of straining hydrophone (99245559.6).Originally the magnetic valve 4 of straining hydrophone is loaded on the drainpipe 2 outside the cesspool 12, the bottom of floating drum 1 is connected in 7 belows, water district of scum silica frost shielded box 6 with pipeline 5, the water inlet 8 of scum silica frost shielded box 6 is positioned under the water surface, and open wide downwards, the bed mud precipitation that is suspended in is wherein fallen, draining weir 9 is housed in the scum silica frost shielded box 6, its crest of weir is higher than the water surface 10～20mm, therefore when normal aeration, bed mud can not crossed crest of weir and enter in the drainpipe.Be provided with buoyancy adjustment mouth 11 at the top of floating drum 1, the water surface 10 and the distance of crest of weir can be adjusted to optimum value, both helped steady draining, again not disturbance bed mud.The shape of the floating drum 1 of this device is fabricated to cylinder, being shaped as the circular arc cylinder and being surrounded on the outside of floating drum 1 of scum silica frost shielded box 6, it is circular-arc that its draining crest of weir also should be mutually, has long length, therefore elementary stream speed is very little, water body and bed mud are not almost had disturbance, and so in addition layout can reduce materials and floor space under maximum volume.

Claims

1, hydrophone is strained in a kind of unpowered external control, form by floating drum, drainpipe, telescoping tube and magnetic valve, it is characterized in that magnetic valve is loaded on the outer drainpipe of cesspool, the water district that on floating drum, connects the scum silica frost shielded box with pipeline, the water inlet of scum silica frost shielded box is in the underwater and the draining weir wherein is housed, and the draining crest of weir is higher than the water surface.

2, strain hydrophone by the described unpowered external control of claim 1, it is characterized in that the draining crest of weir is higher than the water surface 10～20mm, is provided with the buoyancy adjustment mouth at the top of floating drum.

3, strain hydrophone by the described unpowered external control of claim 1, it is characterized in that the cylinder that is shaped as of floating drum, being shaped as the circular arc cylinder and being surrounded on the floating drum outside of scum silica frost shielded box.
