Detailed Description

The following description is merely exemplary in nature and is not intended to limit the present disclosure, application, or uses. It should be understood that throughout the drawings, corresponding reference numerals indicate like or corresponding parts and features.

As shown in fig. 1 and fig. 2, the high-efficiency flushing door of the embodiment of the present invention includes a flushing tank 8 and a regulating tank 1, wherein the flushing tank 8 is adjacent to the regulating tank 1, one side of the flushing tank 8 is disposed in the regulating tank 1, the flushing tank 8 is higher than the regulating tank 1, a flushing door 5 is disposed at the bottom of the tank wall between the flushing tank 8 and the regulating tank 1, a communication hole is disposed in the middle of the tank wall between the flushing tank 8 and the regulating tank 1, and a solenoid valve 9 is disposed on the communication hole; a closed cover plate is arranged at the top of the washing tank 8, and a vacuum device is arranged on the cover plate; the other side of the regulation and storage tank 1 is provided with a water collecting pit 10, and a drain pipe 3 is arranged in the water collecting pit 10.

Wherein, a closed cover plate is arranged at the top of the flushing tank 8 and used for preventing external air from entering the flushing tank 8. When the vacuum flushing device works, water in the regulating storage tank 1 flows into the flushing tank 8 through the flushing door 5 and the electromagnetic valve 9, and when the flushing tank 8 is vacuumized through the vacuum device, the water in the regulating storage tank 1 flows into the flushing tank 8 under the action of atmospheric pressure, so that the water quantity in the flushing tank 8 is further increased; when the adjustable storage tank 1 needs to be washed, rainwater in the adjustable storage tank is drained, then air in the washing tank 8 is reduced through the vacuum device, the washing door 5 is opened again, rainwater at a high liquid level in the washing tank 8 is flushed out, and the sediment at the bottom of the adjustable storage tank 1 is washed completely.

In the efficient flushing door of the above embodiment, preferably, the vacuum device comprises a vacuum pump 7 and a vacuum valve 6, the vacuum pump 7 is used for sucking air above the flushing pool 8 to form vacuum; the vacuum valve 6 is connected to the top surface of the washing tank 8, and the vacuum valve 6 is used for allowing external air to enter the top of the washing tank 8.

The vacuum valve 6 controls the external air to enter the top of the washing tank 8, so that the top of the washing tank 8 is communicated with the atmosphere, and the air pressure is reduced.

Preferably, when in use, the installation height of the electromagnetic valve 9 is slightly lower than the normal washing liquid level of the washing pool 8. In order to ensure that the electromagnetic valve 9 can normally operate, the liquid level in the storage tank 1 needs to be higher than the height of the electromagnetic valve 9. When the flushing reservoir 8 is evacuated, the flow of water from the reservoir 1 enters the flushing reservoir 8, and the solenoid valve 9 is used to prevent the flow of water from the flushing reservoir 8 to the reservoir 1.

Preferably, when the number of the galleries 2 is more than two, the galleries 2 are arranged longitudinally. Each corridor 2 is of the same width and operates simultaneously.

Preferably, a water pump 4 is further arranged in the sump 10. The water pump 4 is used for discharging the mixed liquid after washing, and the water pump 4 and the drain pipe 3 both flow out of the storage tank 1.

The working process of the efficient flushing door of the embodiment is as follows: before washing, open washing door 5 through hydraulic pressure mechanism, make in the regulation pond 1 rainwater enter into washing tank 8 through its hole, open solenoid valve 9 simultaneously with this, also make in the regulation pond 1 rainwater enter into washing tank 8 through solenoid valve 9, when the liquid level height of washing tank 8 and the normal liquid level height that washes of regulation pond 1 are equal, close gate-type rinse-system. Then the vacuum valve 6 on the top plate of the washing tank 8 is closed, the communication between the washing tank 8 and the outside air is cut off, and the vacuum pump 7 is started to vacuumize the top of the washing tank 8. At this time, rainwater in the regulating reservoir 1 enters the flushing reservoir 8 through the electromagnetic valve 9 under the action of atmospheric pressure, so that the liquid level of the flushing reservoir 8 is further improved, the liquid level height of the flushing reservoir 8 is H, the liquid level height of the regulating reservoir 1 is H1, the liquid level height H of the flushing reservoir 8 is H2 higher than the liquid level height H1 of the regulating reservoir 1, the numerical value of H2 is equal to the vacuum degree, and the vacuum degree can be improved by 6-7 m. After the electromagnetic valve 9 and the vacuum pump 7 are closed, the rainwater in the storage tank 1 is discharged through the drain pipe 3. And finally, opening the door type flushing system, instantly releasing the stored water in the flushing tank 8 by the flushing door 5, enabling the water sprayed out of the bottom of the flushing door 5 to have high speed, forming strong mat-rolled jet flow, flushing and flowing the sediment at the bottom of the tank into a water collecting pit 10 at the tail end of the regulating and storing tank 1 by the wave formed by the jet flow, discharging the sediment through the water pump 4, and storing the water again.
