Background

In the field of liquid or sewage collection technology, the collection of liquid or sewage by vacuum technology is a conventional technology, and although domestic technology has been relatively short in accumulation time, the technological development in recent years has been rapidly advanced, and a special aspect in the field is the working mechanism and method of aeration, water collection and drainage of a vacuum sewer valve and a pressure difference driven controller in a vacuum well, wherein the following application scenes are included: domestic sewage (such as black water represented by waste water sources such as urinals, toilets, and grey water represented by waste water sources such as kitchens, changing and bathing) from buildings (such as rural flats, cottages, buildings, cement houses, villas, and urban residential buildings, tall buildings, etc.) is transported to a remote sewage tank or vacuum collection transport piping system by means of pipes based on the principle of vacuum or negative pressure airflow transport force that draws air in at one end and discharges air at the other end.

The typical technical scheme for realizing the application scene is to adopt a temporary sewage storage tank, wherein the sewage storage tank is provided with an inlet connected with a sewage port of a building, a sewage suction inlet connected with a vacuum sewage conveying pipeline, and a vacuum sewage valve connecting the sewage suction inlet and the vacuum sewage conveying pipeline, the vacuum sewage valve is provided with a control system or a device, the basic operation process is that when the sewage level in the storage tank reaches a first preset value, a controller applies vacuum force to the vacuum sewage valve to suck and empty the sewage until the sewage level in the sewage tank falls to another preset value, the control system closes the vacuum sewage valve, and the technical scheme is defined as a vacuum sewage continuous collection, temporary storage and periodic conveying system, namely a vacuum well system.

Due to the technical development and the increased awareness of the functions and needs, vacuum wells have been provided with pneumatic controllers which are not actively ventilated, as in US invention patent No. US3998736, which uses a vacuum well, which is technically characterized in that the vacuum blowoff valve and the pneumatic controller are separate equipment chambers outside the sewage chamber of the vacuum well, and both use a sealed well cover to ensure that the equipment chamber and the sewage chamber are not affected by surface sewage, especially heavy rain. However, with the development of the technology, the vacuum well is completely converted into an active ventilation scheme through the initial non-ventilation technical mode; as is well known, the vacuum well is internally divided into an equipment cavity and a sewage cavity by a sealing clapboard, a pneumatic controller and a vacuum blowoff valve are both arranged in the equipment cavity, the ventilation function is the main function of the pneumatic controller and the vacuum blowoff valve in the vacuum well, and a large amount of air is needed for reliable operation, and the known ventilation schemes of the pneumatic controller and the vacuum blowoff valve for the vacuum well have the following three types:

1. the most representative technical scheme is a sewage cavity ventilation type vacuum well:

US patent nos. US469173 and US5570715 provide a new vacuum well sewage chamber aeration, sump-pumped method, i.e. an aeration line arranged near the building, integrated with a gravity sewage collection line for collecting the sewage of the building into the vacuum well by gravity flow, and above the ground, although the vacuum well sewage chamber (or sewage tank, sewage chamber) aeration, sump-pumped method omits ground aeration facilities near the vacuum well, but has many problems, such as high cost and poor functionality; according to the scheme, an extra pipeline is needed to communicate the sewage cavity with the vacuum blowoff valve and the controller thereof, and under certain conditions, sewage can also enter the controller and the vacuum blowoff valve, so that products are damaged and need to be maintained; more seriously, the air from the sewage chamber below in the vacuum well is often humid and sometimes damp and hot, so that condensation occurs in the ventilation lines, which in turn affects the use of valves and controls.

EP0990743a2 patent document teaches to avoid the ingress of sewage into the upper chamber by providing a vent port in the vacuum well between the sewage chamber and the equipment chamber in a sealed partition in which a float level valve is mounted, typically to allow air flow in the upper and lower chambers, and to close the vent when the sewage reaches above a high level. The technical scheme solves the problems in the prior art to a certain extent, but as is well known, sewage contains a large amount of impurities, the impurities in the sewage enter the floating ball assembly, so that a floating ball and a rubber sealing ring can be corroded, and the impurities in the sewage adhere to the vicinity of a plug matching surface to cause the fault of the on-off function of the floating ball liquid level valve, so that the function is invalid; and because this embodiment of the solution avoids the expense required to customize the well lid, a non-sealed (with vent holes and piping) conventional well lid is used, and ground water can enter the upper chamber and contaminate the controller. More seriously, this solution, although provided with a general vent filter, has the inlet of the filter directed upwards, which further causes the collection and entry of the condensed water into the circuit.

2. The other technical scheme is that the equipment cavity ventilation type vacuum well comprises:

specifically, the technical proposal for ventilating the vacuum well equipment cavity is known as representative technical proposal, namely European Union patent EP0519523A2 and U.S. Pat. No. US5570715, which provides a new vacuum well pneumatic controller and a method for ventilating the vicinity of the vacuum well cover; near ventilation pipe ventilation formula technical scheme main characteristic of vacuum well is sealed well lid, near well lid configuration ventilation pipeline, and this ventilation pipeline entry is located subaerial, has a distance with ground, can avoid sewage to get into, and the ventilation pipeline export is located vacuum well equipment chamber, through a trachea and pneumatic controller air inlet switch-on, rather than directly with ventilation pipeline export and vacuum well equipment chamber UNICOM.

3. The last technical scheme is that the well cover ventilation type vacuum well comprises:

the technical scheme of the well cover ventilation type is that the traditional non-sealed well cover is adopted for ventilation, and the problems are very typical, such as the problem of surface water accumulation, particularly the problem of breakdown of a pneumatic controller and the breakdown of vacuum well equipment caused by the fact that sewage enters a vacuum well equipment cavity in flood and heavy rain days; however, the vacuum well is used for collecting waste water generated by resident schedule domestic water, mainly comes from kitchen and bathroom domestic sewage, and if the kitchen and bathroom domestic sewage cannot be drained in time, the unavailable vacuum well can seriously affect the convenience of the schedule life of residents; however, the domestic situation is particularly unattractive overall, since the technology development is short.

The vacuum well for ventilating the inside of the equipment cavity is usually provided with a ventilation pipeline near a building, and the arrangement mode has certain limitations, for example, the ventilation pipeline near the building affects municipal aesthetics and building aesthetics, and an owner does not have to make construction or construction positions limited, for example, the distance is too long, the lifting bend is too much, so that the air circulation resistance is large, and the ventilation effect of the vacuum well is reduced; high place configuration vacuum well, for example on the hillock, and the building is in low-lying department, if with ventilation pipe configuration near the building, then because the quantity that promotes is bent huge, the cost is high, and the ventilation pipe of low-lying department leads to the flood to get into ventilation pipe owing to receiving the stormy rain season, for example plum rain season, and then influences the ventilation effect of vacuum well, leads to the long-term work of vacuum well and life reduces moreover, and power consumption is huge.

The communication mode inside the pneumatic controller 2 is: the middle parts of the first cavity 201, the second cavity 202 and the third cavity 203 are communicated, the third cavity 203 and the fourth cavity 204 are communicated through a needle valve 217 capable of adjusting flow, the fourth cavity 204 is communicated with the middle part of the fifth cavity 205, an air flow passage 218 is communicated with an air inlet 211 and an air interface of the vacuum blow-down valve 3 (the air flow passage 218 is communicated with an outer end), the air flow passage 218 is communicated with the first cavity 201 and the fifth cavity 205 (the air flow passage 218 is communicated with an inner end), a pneumatic control interface A213 of the vacuum blow-down valve is communicated with the second cavity 202, a vacuum inlet A215 is communicated with the third cavity 203, and a liquid level sensor interface A214 is communicated with the sixth cavity 206.

when the liquid level in the sewage chamber 11 rises, the air pressure above the liquid level in the liquid level circulation pipeline 41 is increased, so that the pressures at the liquid level sensor interface B42 and the liquid level sensor interface A214 are increased, and according to the working principle of the pneumatic controller 2, when the liquid level sensor interface A214 is in a high-pressure state, the actuating mechanism 22 and the control mechanism 23 both move, so that the pneumatic control interface A213 of the vacuum blowoff valve is communicated with the vacuum inlet and outlet, and the vacuum blowoff valve is formed in the pneumatic control interface A213.

(2) The pneumatic control interface A213 of the vacuum blowoff valve is communicated with the pneumatic control interface B312 of the vacuum blowoff valve:

after vacuum is formed in the vacuum blow-off valve pneumatic control interface A213, vacuum is also formed at the vacuum blow-off valve pneumatic control interface B312, and the vacuum blow-off valve 3 is opened to blow off when vacuum is formed in the vacuum blow-off valve pneumatic control interface B312 according to the working principle of the vacuum blow-off valve 3.

(3) Vacuum inlet and outlet a215 and vacuum inlet and outlet B313 communicate:

since the vacuum blowoff valve 3 is connected to the downstream vacuum pump station 03, the vacuum inlet/outlet B313 is always in a vacuum state, and therefore the vacuum inlet/outlet a215 connected thereto is also always in a vacuum state.

(4) The vacuum blowoff valve air interface a212 is in communication with the vacuum blowoff valve air interface B311:

when the vacuum blowoff valve 3 is in a working state, air above the blowoff membrane 32 needs to be discharged, and at the moment, the air is discharged into the vacuum blowoff valve air interface A212 through the vacuum blowoff valve air interface B311; when the vacuum blowoff valve 3 is in a non-working state, air needs to be supplemented above the blowoff membrane 32, and at the moment, air is introduced into the vacuum blowoff valve air interface B311 through the vacuum blowoff valve air interface a 212.

(5) The condensate inlet 54 communicates with the condensate outlet 216:

in the process of introducing air into the air flow passage 218 through the air inlet 211, the air passes through the filter block 219 for removing dust and filtering the air, removing impurities in the air, intercepting condensed water in the air, and finally discharging the condensed water from the condensed water outlet 216, wherein the discharged condensed water flows into the water collecting chamber 53 along the water collecting pipeline 51.

(6) The drain connector 57 is communicated with one end of the vacuum blowoff valve 3 deviated to the water inlet connector 314:

when the liquid level in the sewage cavity 11 begins to descend, the liquid level in the sewage suction pipeline 62 connected with the water inlet interface 314 also begins to descend, and the air pressure is reduced, so that the sewage in the water collecting cavity 53 is sucked into the sewage cavity, the working requirements of each device in the equipment cavity on the dry environment are effectively guaranteed, and the working efficiency and the service life of the equipment are greatly improved.
