Example one
Referring to fig. 1-2, an intermittent air pressure emptying device provided in the embodiment of the present disclosure is used for the water storage tank 4 to empty water in the water storage tank 4, and includes: a housing 1, an evacuation assembly 11, and a gas delivery assembly 2.
Before describing the first embodiment of the present specification in detail, it should be additionally noted that, according to the research of the new people, the water storage tank has a large volume, 6m3、12m3、20m3、50m3When the water storage tank with the large volume is drained by avoiding the pump drainage mode and is drained by directly filling compressed air, the tank body structure of the whole water storage tank needs to be a sealed chamber, but the water storage tank needs to be provided with an access hole in consideration of later maintenance and flushing, so that the whole air tightness is ensured, the water storage tank is very difficult, and the drainage effect is very poor. Meanwhile, the large-volume water storage tank needs to be emptied by air pressure, and the tank body structure needs to have certain strength and can bear certain pressure, so that the existing water storage tank is very high in manufacturing cost. Therefore, even if the water storage tank is filled with compressed air by itself and drained by using an air pressure emptying mode, the technical defects of poor drainage effect and high manufacturing cost exist.
Based on this, the utility model discloses the novelty provides above-mentioned intermittent type formula atmospheric pressure emptying devices, specifically is: the housing 1 is provided with a hollow structure 12 for carrying or storing water. The gas delivery assembly 2 is respectively communicated with the hollow structure 12 and the outside atmosphere; the emptying assembly 11 is arranged on the shell 1 and communicated with the water storage tank 4, and an on-off switch 41 is arranged at the communication part of the emptying assembly 11 and the water storage tank 4. In the actual operation process, the domestic sewage in the unit area firstly enters the water storage tank 4, when the water in the water storage tank 4 needs to be discharged, that is, when water enters the housing 1, the on-off switch 41 is in an open state, the hollow structure 12 is communicated with the outside atmosphere through the gas delivery assembly 2, the air pressure in the hollow structure 12 is communicated with the external atmospheric pressure, the water in the water storage tank 4 can enter the hollow structure 12 through the emptying component 11 without resistance, when it is desired to continue to drain the water in the housing 1 downstream, i.e., to drain the water from the housing 1, air is introduced into the hollow structure 12 through the gas delivery module 2, since the entire hollow structure 12 is in a sealed state at this time, the air pressure is created by the air introduced into the hollow structure 12 by the air delivery module 2, and under the action of this air pressure, the water is drained from the hollow structure 12 through the emptying assembly 11. After a part of water in the hollow structure 12 is discharged to form a residual accommodating space, the process is continuously repeated at the moment, namely the on-off switch 41 is turned on, the hollow structure 12 is communicated with the external atmosphere through the gas conveying assembly again, water in the water storage tank enters the hollow structure through the emptying assembly, and an intermittent air pressure discharge mode is formed in a circulating mode, so that the technical defects that the water storage tank is drained in an air pressure emptying mode in the prior art are replaced, the water storage tank is poor in sealing performance due to the fact that the volume of the water storage tank is large, the drainage effect is poor, and the manufacturing cost is high are overcome, and the technical effects of simplicity in operation and low cost are achieved.
Specifically, the gas delivery assembly 2 in the embodiments of the present description may include an inlet pipe 21 and an outlet pipe 22. Wherein, the air inlet pipe 21 comprises an air input end 211 communicated with an external air source and an air output end 212 for outputting air, which can be understood as two ends of the air inlet pipe 21, the air output end 212 is arranged in the hollow structure 12, the air inlet pipe 21 is provided with an air inlet valve 23 near the air input end 211, and the air inlet valve 23 is arranged in the outer area of the shell 1. One end of the outlet pipe 22 is connected to the hollow structure 12 and the other end is connected to the outside atmosphere, it is understood that the end of the outlet pipe 22 connected to the hollow structure 12 is disposed on the housing of the housing 1, the other end connected to the outside atmosphere is disposed in the outer region of the housing 1, and the outlet pipe 22 is provided with an outlet valve 24.

In the embodiment of the present invention, the ventilation pipe 3 is transversely distributed in the bottom area of the hollow structure 12, and the "transverse distribution" is only relative to the plane of the bottom of the hollow structure 12, and similarly, it can be understood by those skilled in the art that the slight upward or downward inclination of the ventilation pipe 3 relative to the bottom of the hollow structure 12 during the actual operation will not affect the stirring effect, and it should not be considered that the ventilation pipe 3 is not transversely distributed relative to the bottom area of the hollow structure 12, and the protection scope of the present invention is not limited thereto.
Meanwhile, in order to prevent the vent holes 31 from being clogged with contaminants, it is preferable that the vent holes 31 be opened toward the bottom of the hollow structure 12.
As an embodiment, the evacuation assembly 11 in the embodiment of the present specification may include an inlet pipe 112 and an outlet pipe 113. That is, in this embodiment, the emptying assembly 11 can simultaneously realize water inlet and water outlet, wherein one end of the water inlet pipe 112 is communicated with the hollow structure 12, and the other end is communicated with the water outlet 42 of the water storage tank 4 through the on-off switch 41; one end of the water outlet pipe 113 is disposed at the bottom of the hollow structure 12 and communicates with the hollow structure 12, and the other end is disposed in the outer region of the housing 1.
