Description

Technical Field

[0001] The present invention relates to the technical field of vacuum toilets, and particularly relates to a waterless vacuum toilet collection system. Background Art

[0002] The water supply and discharge of toilets have troubled people for many years. Especially in areas without urban pipe networks, as well as on mobile vehicles such as cars, ships, etc., the filling of clean water and the discharge of sewage are troublesome headaches; and existing vacuum toilets use water as the pushing medium, which is not easy to separate from dirt after flushing and discharging, and cannot be recycled. This not only increases the discharge volume, but also causes harm to the environment.

[0003] Currently, there are mainly three methods for waterless toilet technology: plastic bag type, foam plugging type, and biodegradable type. They all have a common problem, that is, the experience is poor, and they give people impressions of being unsafe, unhygienic, and having odors. They are relatively low-end products.

[0004] As the best product among water-saving toilets, vacuum toilets still require 0.5 liters of water for flushing and discharging during a single use. This means that each discharge needs to increase 0.5 liters of sewage (the total amount of sewage after a single flushing and discharging is more than twice the average value of an adult's one-time urination and defecation, which is 0.5 liters). This not only increases the burden of transporting clean water and sewage, but also increases the volume of the water tank. These problems are particularly important for mobile vehicles such as cars and ships. Therefore, there is an urgent need in the market for a toilet that neither uses water, has a good experience, is hygienic and safe. Summary of the Invention

[0032] To make the objectives, technical solutions and advantages of the present invention clearer, the following will describe the technical solutions of the present invention in detail. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other implementation manners obtained by those of ordinary skill in the art without creative efforts belong to the scope protected by the present invention.

[0033] The present invention provides a waterless vacuum toilet system, as Figures 1 - 4As shown in the figure, the anhydrous vacuum toilet system includes a housing 1 and a gas cylinder shell type vacuum sewage discharging device 2, wherein: an accommodation chamber 103 and a separation chamber are arranged inside the housing 1, a pushing medium is contained in the accommodation chamber 103, the gas cylinder shell type vacuum sewage discharging device 2 is arranged on the housing 1, a sewage discharging body 3 and the separation chamber are both connected to the gas cylinder shell type vacuum sewage discharging device 2, a conveying pipeline is connected to the accommodation chamber 103 in a communicating way, the conveying pipeline includes a conveying front pipe 41, a conveying middle pipe 42 and a conveying pipe 4 which are connected in sequence, the conveying pipe 4 is connected to the sewage discharging body 3, a part of the conveying middle pipe 42 is located inside the gas cylinder shell type vacuum sewage discharging device 2, and an electromagnetic water valve 19 is arranged thereon.

The gas cylinder shell type vacuum sewage discharging device 2 adopts an existing device, and the sewage discharging body 3 is a toilet, a squatting pan, etc.; the separation chamber is used for separating the pushing medium in the sewage, the separation chamber is communicated with the accommodation chamber 103, and the separated pushing medium can flow back to the accommodation chamber 103.

[0034] When flushing and discharging the sewage, the pushing medium in the accommodation chamber 103 enters the sewage discharging body 3 and flushes and discharges the sewage, and then enters the separation chamber under the action of the gas cylinder shell type vacuum sewage discharging device 2. In this process, the gas cylinder shell type vacuum sewage discharging device 2 generates a high-speed air flow, and the feces are broken into powder in the jet pipe of the gas cylinder shell type vacuum sewage discharging device 2 and mixed with urine and air to form a gas-liquid mixture; then the gas-liquid mixture enters the separation chamber for separation, and the separated pushing medium flows back to the accommodation chamber 103.

[0035] The present invention can realize anhydrous sewage discharging through the pushing medium, which is safe and hygienic. On the basis of ensuring the flushing and discharging effect, the gas cylinder shell type vacuum sewage discharging device 2 can effectively save the consumption of the pushing medium. The separation chamber can effectively separate the pushing medium to realize recycling; as a whole, it not only has a compact structure, a small volume and is convenient for installation, but also has the function of energy conservation and emission reduction.

[0036] As an optional implementation manner, the density of the pushing medium is less than the density of water.

[0037] The pushing medium is set as white oil, and the white oil adopts 1-3 grade cosmetic white oil. Its technical parameters and technical effects are as follows:

[0038] 1. Low density, about 0.8g / cm3 , facilitating separation;

[0039] 2. Colorless, odorless, non-toxic, harmless to the human body, and hygienic and safe to use;

[0040] 3. Non-flammable, with a flash point of 130°C and unable to be ignited at room temperature;

[0041] 4. Low pour point, -10°C, and can work in low-temperature environments;

[0042] 5. Insecticidal and bactericidal, and general organisms cannot survive;

[0043] 6. Low viscosity, close to that of water, the inner surfaces of the toilet and pipeline are smooth and non-sticky, facilitating cleaning;

[0044] 7. Low cost and easy to obtain;

[0045] 8. Compared with water, white oil is easier to purify and separate, and the purification and separation cost is low;

[0046] 9. During the storage of urine, due to the isolation of the oil layer on the upper layer all the time, there is neither odor nor the spread of bacteria can be inhibited.

[0047] As an optional implementation manner, as Figure 1 shown, the separation chamber includes a gas-liquid separation chamber 101 and an oil-water separation chamber 102.

[0048] The liquid inlet 110 of the gas-liquid separation chamber 101 is communicated with the gas cylinder shell type vacuum sewage discharge device 2. The gas-liquid separation chamber 101 is used to separate the waste gas in the sewage; the liquid discharge port of the gas-liquid separation chamber 101 is communicated with the oil-water separation chamber 102. The oil-water separation chamber 102 is used to separate the pushing medium in the sewage. An overflow port 109 is arranged at the upper side position of the oil-water separation chamber 102, and the oil-water separation chamber 102 is communicated with the accommodation chamber 103 through the overflow port 109.

[0049] As an optional implementation manner, as Figure 1 shown, a partition is vertically arranged inside the housing 1. The partition divides the internal cavity of the housing 1 into the separation chamber and the accommodation chamber 103. A liquid collecting plate 104 is arranged in the separation chamber. The liquid collecting plate 104 is located above the partition and divides the separation chamber into a gas-liquid separation chamber 101 and an oil-water separation chamber 102 which are hierarchically arranged from top to bottom.

[0050] An exhaust pipe 106 is communicatedly arranged at the top of the gas-liquid separation chamber 101. An upper cover plate 107 is arranged on the housing 1 above the gas-liquid separation chamber 101. The upper cover plate 107 is hinged to the housing 1 through a hinge. The upper cover plate 107 is made of stainless steel. The internal cleaning and maintenance of the separation chamber are facilitated through the openable upper cover plate 107.

[0051] The liquid collecting plate 104 is inclined, the drain port is arranged at the lowest position of the liquid collecting plate 104, and the drain port is located below the liquid inlet 110 of the gas-liquid separation chamber 101. The inclined liquid collecting plate 104 mainly guides most of the gas to the exhaust pipe 106 to reduce the pressure on the drain port and concentrate the separated liquid to the drain port.

[0052] A narrow slit is provided between the lowest position of the liquid collecting plate 104 and the inner wall of the housing 1, and the narrow slit forms the drain port. When the liquid level in the oil-water separation chamber 102 is low, the liquid separated from the gas-liquid flows down along the deflector plate 7 below the drain port to reduce the liquid level disturbance caused by splashing; when the liquid level in the oil-water separation chamber 102 is high and close to the upper limit, the liquid level disturbance caused by the instantaneous air pressure increase can be reduced; preferably, the cross-sectional area of the narrow slit drain port is one-tenth of the liquid level area of the oil-water separation chamber 102. When the liquid level of the narrow slit drops by one unit due to the instantaneous pressure, the liquid level of the oil-water separation chamber 102 only drops by one-tenth of a unit, which can greatly reduce the liquid level fluctuation. This setting method is particularly important when the sewage is close to the upper limit.

[0053] A sewage discharge pipe 105 is connected to the bottom of the side wall of the oil-water separation chamber 102, and a manual sewage discharge butterfly valve 13 is provided at the sewage discharge port of the sewage discharge pipe 105. When urine and feces need to be discharged, it is controlled to open and close manually.

[0054] As an optional implementation manner, as Figures 1 - 3 shown, a gas combing curtain 6 is arranged in the gas-liquid separation chamber 101, and the gas cylinder shell type vacuum sewage discharge device 2 is connected to the liquid inlet 110 of the gas-liquid separation chamber 101 through a sewage conveying pipeline 20; the gas combing curtain 6 is arranged in the gas-liquid separation chamber 101 and is located between the liquid inlet 110 and the exhaust pipe 106.

[0055] The gas combing curtain 6 is composed of a group of silica gel strips. During flushing and discharging, the gas-liquid mixture discharged from the gas cylinder shell type vacuum sewage discharge device 2 enters the gas-liquid separation chamber 101. Under the action of the gas combing curtain 6, the air is discharged upward through the exhaust pipe 106, and the sewage flows along the liquid collecting plate 104 to the drain port and enters the oil-water separation chamber 102.

[0056] As an optional implementation manner, a deflector plate 7 is arranged in the oil-water separation chamber 102. The deflector plate 7 is inclined and is located below the drain port. The deflector plate 7 is an inclined wall plate inside the housing 1. When the liquid level is low, the inclined deflector plate 7 can make the sewage flowing out of the drain port descend slowly, effectively reducing the disturbance to the liquid level caused by splashing.

[0057] A wave blocking plate 8 is arranged in the oil-water separation chamber 102. The wave blocking plate 8 is vertically and rotatably arranged in the oil-water separation chamber 102 and can float on the sewage liquid surface. The wave blocking plate 8 includes a wave blocking part and a connecting part. One end of the connecting part is rotatably arranged in the oil-water separation chamber 102, and the other end of the connecting part is connected to the wave blocking part. The wave blocking part is arranged as a plate body, which is made of plastic material and has a hollow structure. The plate body includes section plates that are rotatably connected in sequence and can adapt to liquid surfaces of different heights. The material density of the wave blocking plate 8 is slightly less than the density of oil, so that most of it can be immersed in oil. On the one hand, when the urine reaches the limit position, the oil liquid can be squeezed to the accommodation chamber 103 through the overflow port 109 to the maximum extent. On the other hand, when the urine is drained, the loss of oil liquid can be minimized as much as possible. The connecting part is made of a thin, light and soft cloth material. When the liquid level is low, the wave blocking plate 8 naturally hangs down to form a curtain wall, which can prevent the influence of air flow on the oil-water separation chamber 102 and keep the liquid surface stable. When the liquid level is high, the wave blocking plate 8 floats up, which can reduce the liquid surface disturbance caused by the movement of the carrier (this effect is mainly for mobile carriers such as vehicles and ships).

[0058] As an optional implementation manner, the anhydrous vacuum toilet system includes a liquid level sensing device 9. The liquid level sensing device 9 includes a liquid level sensing component 91 and an alarm component 92. The alarm component 92 is electrically connected to the liquid level sensing component 91. The liquid level sensing component 91 is arranged in the oil-water separation chamber 102 and below the overflow port 109. During the continuous use of the toilet, the liquid surface in the oil-water separation chamber 102 will gradually rise, and the oil layer floats on the urine. When the liquid surface of the oil layer reaches the overflow port 109, the oil will continuously overflow, and the urine liquid surface continues to rise. When the urine reaches the position of the liquid level sensing component 91 below the overflow port 109, the liquid level sensing component 91 will be triggered. The liquid level sensing component 91 senses the liquid level signal and transmits it to the alarm component 92, and the alarm component 92 is turned on to remind the user that the dirt is full and needs to be cleaned in time.

[0059] Preferably, the liquid level sensing device 9 uses a low voltage below 24V. The alarm component 92 is arranged as an alarm lamp, and the liquid level sensing component 91 is arranged as a liquid level sensing electrode. The liquid level sensing electrode is mainly used to utilize the characteristics that white oil is non-conductive while urine is conductive. The liquid level sensing electrode is arranged at a position 10 mm below the overflow port 109.

[0060] As an optional implementation manner, a filter 11 is arranged in the accommodation chamber 103. The filter 11 includes a filter body and filter cotton.

[0061] The filter body is in the shape of a strainer and is located below the overflow port 109. The bottom wall is provided with leakage holes. The bottom wall of the filter body is inclined downward in a direction away from the overflow port 109, and the inclination angle is 10°, so that the oil liquid overflowing from the overflow port 109 of the oil-water separation chamber 102 is more evenly dispersed and filtered.

[0062] The filter body is provided with a handle, and the handle passes through the housing 1; a top cover 108 is provided above the filter 11 on the housing 1. The top cover 108 is hinged to the housing 1 through a hinge. By opening the top cover 108 and pulling the handle, the filter 11 can be taken out to replace the filter cotton.

[0063] The filter cotton is arranged inside the filter body. The filter cotton adopts a double-layer structure of special filter cotton for fish tanks, and the filter cotton needs to be replaced every time the oil-water separation chamber 102 is emptied.

[0064] As an optional implementation manner, a disinfection device 12 is arranged in the accommodation chamber 103. The disinfection device 12 includes a submersible ultraviolet disinfection lamp, which can kill the bacteria remaining in the oil liquid and ensure the safer and more hygienic use of the oil liquid.

[0065] As an optional implementation manner, the waterless vacuum toilet system includes a diaphragm booster pump 5. The diaphragm booster pump 5 is arranged on the pre-conveying pipe 41, and the diaphragm booster pump 5 provides sufficient pressure for the oil liquid flushing and discharging.

[0066] As Figure 4 shown, the waterless vacuum toilet system includes a control box 14. The control box 14 is connected to a 24V power supply 15. The gas cylinder shell type vacuum sewage discharge device 2 is provided with an air pipe 17. An electromagnetic air valve is arranged on the air pipe 17. The gas cylinder shell type vacuum sewage discharge device 2 is connected to an air pump. The air pump provides compressed air for the gas cylinder shell type vacuum sewage discharge device 2. The compressed air provides power for the sewage flushing and discharging. An electromagnetic water valve 19 is arranged on the section of the middle conveying pipe 42 located inside the gas cylinder shell type vacuum sewage discharge device 2. The electromagnetic air valve, the electromagnetic water valve 19 and the diaphragm booster pump 5 are all electrically connected to the control box 14. The control box 14 controls the opening and closing of the electromagnetic air valve, the electromagnetic water valve 19 and the diaphragm booster pump 5. The starting times of the diaphragm booster pump 5 and the electromagnetic water valve 19 are the same.

[0067] The present invention has technical advantages such as energy conservation, emission reduction, low cost, compact structure, small volume and convenient installation as a whole, as follows:

[0068] First, by adopting the oil-water separation closed-loop circulation technology, there is no need to add clean water, which reduces the setting of the water tank and also saves water resources and the labor for transportation.

[0069] Second, separating urine from oil can significantly reduce the sewage discharge volume (by approximately two-thirds), reduce the volume of the sewage tank, as well as the workload of subsequent transportation and treatment;

[0070] Third, taking a small-scale waterless vacuum toilet system as an example, its total equipment volume is 115 liters, among which the sewage storage volume is 22 liters, and it can be continuously used 110 times after being emptied once, and the oil storage volume is 17 liters. Since the pushing medium has been separated through oil-water separation, the actual sewage storage volume of 22 liters (mainly urine and fecal residues) is equivalent to the storage volume of about 100 liters of the existing vacuum toilet sewage tank. In addition, the existing vacuum toilet also has a water tank (whose capacity is generally not less than 60 liters) and vacuum equipment. It can be seen that the present invention has the characteristics of compact structure, small volume and convenient installation compared with the existing vacuum toilet.

[0071] As described above, the above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
