Description

A kind of siphonic decant device

Technical field

The utility model is a kind of siphonic decant device, belongs to the wetting system of straining that sewage disposal aerobic sequencing batch formula Activated Sludge Process uses, and belongs to the renovation technique of siphonic decant device.

Background technology

Along with being gradually improved of sequencing batch active sludge, increasing sanitary sewage disposal factory and Industrial Wastewater Treatment engineering adopt this technology, and the key that wetting system is above-mentioned technology operation is simply strained in stable maintenance.Mostly the existing large-scale hydrophone of straining is rotary-type water decanter, the rotary-type hydrophone of straining is owing to the higher large-scale sewage disposal project of the complicated proper operation and management level of cost of investment height, drive mechanism and sequence of control, because middle-size and small-size sewage disposal project funds and level of management are limited, the rotary-type hydrophone of straining makes it be difficult to bear.

The utility model content

The purpose of this utility model is to consider the problems referred to above and provides a kind of cost low, and is reliable, siphonic decant device for ease of maintenaince.The utility model is reasonable in design, and is convenient and practical.

The technical solution of the utility model is: siphonic decant device of the present utility model, include and be in charge of, house steward, transverse tube, the water sucking mouth, overflow port, vapor pipe, exhaust solenoid valve, vertical tube, water shoot, be in charge of, house steward places below the liquid level of sequencing batch activated sludge pond, house steward is the U type, overflow port is positioned at house steward's a wherein top, another top of house steward is connected with vertical tube and is connected with a transverse tube, vertical tube is positioned at more than the liquid level in sequencing batch activated sludge pond, vapor pipe is connected with vertical tube, the end of vapor pipe is equipped with exhaust solenoid valve, water shoot and total pipe coupling, and water shoot passes the body of wall in sequencing batch activated sludge pond, be connected with on the transverse tube and be in charge of, and be in charge of and be provided with the water sucking mouth.

The both sides of above-mentioned transverse tube are connected with some being in charge of respectively.

Above-mentioned some both sides that symmetry is connected transverse tube of being in charge of.

The utility model is owing to adopt the structure that is connected and be provided with exhaust solenoid valve by plurality of conduits, and therefore, the utility model cost of investment is low, and operation is simple; In addition, the utility model only need be operated exhaust solenoid valve and get final product, and is easy to maintenance.The utility model is that a kind of cost is low, and is reliable, siphonic decant device for ease of maintenaince.The utility model is applicable to middle-size and small-size sequencing batch activated sludge art breading project.

Wherein: 1 for being in charge of, and 2 is house steward, and 21 is transverse tube, and 3 is the water sucking mouth, and 4 is overflow port, and 5 is vapor pipe, and 6 is exhaust solenoid valve, and 7 is vertical tube, and 8 is water shoot.

Embodiment

Embodiment:

Structural representation of the present utility model as shown in Figure 1, 2, siphonic decant device of the present utility model, include be in charge of 1, house steward 2, transverse tube 21, water sucking mouth 3, overflow port 4, vapor pipe 5, exhaust solenoid valve 6, vertical tube 7, water shoot 8, be in charge of 1, house steward 2 places below the liquid level of sequencing batch activated sludge pond, house steward 2 is the U type, overflow port 4 is positioned at a wherein top of house steward 2, and when straining hydrophone and break down, water is discharged from overflow port 4.Another top of house steward 2 is connected with vertical tube 7 and is connected with a transverse tube 21, vertical tube 7 is positioned at more than the liquid level in sequencing batch activated sludge pond, vapor pipe 5 is connected with vertical tube 7, the end of vapor pipe 5 is equipped with exhaust solenoid valve 6, water shoot 8 is connected with house steward 2, and water shoot 8 passes the body of wall in sequencing batch activated sludge pond, and water is discharged, be connected with on the transverse tube 21 and be in charge of 1, and be in charge of 1 and be provided with water sucking mouth 3.

The both sides of above-mentioned transverse tube 21 are connected with respectively somely is in charge of 1.In the present embodiment, above-mentioned some both sides that 1 symmetry is connected transverse tube 21 of being in charge of.

In the present embodiment, whole each pipeline of straining hydrophone of the utility model adopts the bonding composition in pvc pipe road.

The concrete operation of the utility model is as follows:

1. in the sequencing batch active sludge technology, water level is constantly to change in the pond, and when a last loop ends, exhaust solenoid valve valve 6 is in opened condition, strains hydrophone and is communicated with atmosphere, and the water level in the pond is in lower-most point A.

2. close exhaust solenoid valve 6, water level in the pond begins to rise, when the water level of straining 3 places, hydrophone water sucking mouth rises to 2 crest of weir following times of house steward, because of waterhead in the U-shaped pipe should be the summation that whole group water sucking mouth 3 place's water levels rise, cause intraductal atmospheric pressure to raise, water sucking mouth 3 place's water levels can not rise above crest of weir, and the water surface to the difference of water sucking mouth 3 place's water levels equals waterhead in the U type pipe in the pond.

3. internal reaction precipitation in pond is finished, and when being in top water-level B in the pond, by liquid level control, opens exhaust solenoid valve 6, and house steward 2 is communicated with atmosphere, and air pressure reduces, and the water level at 3 places, water sucking mouth rises, and supernatant liquor is discharged outside the pond from water shoot 8 by the U-shaped pipe.

4. close exhaust solenoid valve 6, U-shaped pipe and atmosphere cut off, and reduce to house steward's 2 crests of weir when following when water level in the pond, and by syphonic effect, supernatant liquor still can be discharged by the U-shaped pipe.

5. when the water level in the pond reduces as far as possible, control by liquid level, the exhaust solenoid valve 6 of performing fighting, siphon destructive begins to enter next circulation.
