Description
Technical field
The utility model relates to technical field of sewage, specifically a kind of anti-clogging aerated grit chamber.
Background technique
A large amount of inorganic sand, existing sediment outflow side can be deposited by running for a long time, in the sand catcher of aerated grit chamber
Method passes through transporter Sand pump (submersible sewage pump or self priming pump) sediment outflow mostly.Since aerated grit chamber is all made of intermittent sediment outflow,
It is longer when aerated grit chamber sediment outflow interval time, or when upland water sand content sharply increases, sand catcher can be deposited largely
Inorganic sand causes the suction sand mouth of Sand pump to be buried and can not be contacted with water by inorganic sand, causes sand suction pipe to block, Sand pump can not
It works normally.When the inorganic sand of sand catcher is deposited to certain compaction rate, with the mobile sand suction pipe of transporter Sand pump by
To horizontal resistance be gradually increased, cause sand suction pump to deform with sand suction pipe interface, in addition occur sand suction pipe bending fall off.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, provides and a kind of sink to aerated grit chamber sand catcher
Sand is disturbed to improve the anti-clogging aerated grit chamber of aerated grit chamber sediment outflow stability.
In order to achieve the above object, the utility model provides a kind of anti-clogging aerated grit chamber, including aerated grit chamber
Ontology, the immersible pump which is set and the hydrodynamic cleaning pipe laid along the sand catcher of the aerated grit chamber
Road, in which:
The end of hydrodynamic cleaning pipe is arranged in the immersible pump；
The hydrodynamic cleaning pipe is stainless steel straight tube pipeline, which is laid with three column along its axial direction and rinses
Hole, wherein straight line where first row flushing hole line is located at the top of the radial section of the hydrodynamic cleaning pipe, secondary series flushing hole
Line where straight line be located at the hydrodynamic cleaning pipe radial section upper left side, the line place straight line position of third column flushing hole
In the upper right side of the radial section with hydrodynamic cleaning pipe.
Preferably, the immersible pump is low discharge low lift immersible pump.
Preferably, the first row flushing hole, secondary series flushing hole and the flushing hole of third column are opened respectively with equal mode for cloth
It is located in the axial direction of hydrodynamic cleaning pipe.
Preferably, the first row flushing hole line and the plane a where this two straight lines of hydrodynamic cleaning tube axis line

Degree is 45 °.
Immersible pump is arranged in pond end in this anti-clogging aerated grit chamber, and connect with hydrodynamic cleaning pipeline.In transporter
It before Sand pump sediment outflow, opens immersible pump and boosts to water, so that pressure water is vertical, oblique by the aperture on hydrodynamic cleaning pipeline
To ejection, the water flow of high speed injection disturbs the closely knit inorganic sand for being deposited on bottom of pond, plays stirring action, so that sand water is mixed
It closes, increases the moisture content of inorganic sand.Sand suction pipe road uses stainless steel pipes, to effectively prevent inner wall of the pipe heavy corrosion,
A possibility that increasing the resistance of ducting, and then increasing line clogging.Immersible pump uses low discharge low lift immersible pump.
The beneficial effects of the utility model are:
1, the utility model carries out hydrodynamic cleaning by the inorganic sand of deposition to sand catcher, plays the role of hydraulic mixing, makes
Sand mouth must be inhaled not buried by closely knit inorganic sand, sand suction pump can work normally, and while hydrodynamic cleaning, it is aqueous to increase inorganic sand
Rate, it is effective to prevent sand suction pipe and the generation of sand suction pump clogging；
2, the utility model carries out hydrodynamic cleaning by the inorganic sand of deposition to sand catcher, increases inorganic water-containing rate,
The horizontal resistance being subject to when sand suction pipe is mobile during sediment outflow is reduced, ensure that the stability of sand suction pump and sand suction pipe operation；
3, the utility model improves the reliability of aerated grit chamber sediment outflow, also substantially increases aerated grit chamber and subsequent
Handle the stability of structures continuous operation.
