Technical Field

[0001] This utility model relates to a container-type toilet, specifically, to a water circulation treatment system for an integrated ecological toilet using container modules. Background Technology

[0002] Current traditional portable toilets have many drawbacks: 1. Dependent on municipal pipe network: It needs to be connected to the drainage pipe and cannot be used independently in areas without infrastructure.

[0003] 2. Frequent removal and high cost: Sewage and waste need to be frequently removed by vacuum trucks, resulting in strong odor and high operation and maintenance costs.

[0004] 3. Requires a water supply network: Traditional flush toilets require a water supply network.

[0005] 4. Poor deployment flexibility: Fixed buildings or simple sheds are difficult to deploy and relocate quickly.

[0006] 5. No resource utilization: Fecal waste is regarded as waste, not a resource.

[0007] Existing environmentally friendly toilets (such as dry composting toilets and microbial degradation toilets) often have problems such as limited processing capacity, high requirements for operating environment, and high degree of professionalism in post-maintenance. These problems limit the use and dissemination of environmentally friendly toilets. Summary of the Invention

[0008] The purpose of this invention is to provide a water recycling system for an integrated ecological toilet using a container module, in order to solve the problems mentioned in the background art.

[0009] To achieve the above objectives, this utility model provides a water circulation treatment system for an integrated ecological toilet using a container module. The system includes a container, the interior of which is divided into three chambers by two partitions: a working chamber and toilets located on either side. A vacuum rear-discharge toilet is installed in the toilet. The working chamber contains a solid-liquid separation unit, an integrated water treatment unit, a high-temperature aerobic fermentation unit, a disinfection unit, and a recycled clean water tank. The discharge port of the vacuum rear-discharge toilet is connected to the solid-liquid separation unit via a pipe. The liquid separated in the solid-liquid separation unit is transported to the integrated water treatment unit via a pipe. The sediment separated in the solid-liquid separation unit is transported to the high-temperature aerobic fermentation unit via a pipe. The high-temperature aerobic fermentation unit ferments the sediment and transports the resulting liquid to the integrated water treatment unit. The integrated water treatment unit treats the liquid and transports the treated liquid to the disinfection unit. The disinfection unit disinfects the treated liquid and then transports it to the recycled clean water tank. The recycled clean water tank is connected to the inlet pipe of the vacuum rear-discharge toilet via a pipe.

[0010] As a further improvement to this technical solution, a negative pressure collection unit is installed in the bathroom to absorb the gas in the bathroom, and floor drains are installed at the bottom of both the working room and the bathroom.

[0011] As a further improvement to this technical solution, the high-temperature aerobic fermentation unit includes a fermentation tank, which is used to ferment the precipitate. An electric heating device is installed on the fermentation tank to heat the precipitate inside the fermentation tank.

[0012] As a further improvement to this technical solution, a collection tank is provided on the lower side of the fermentation tank, and the collection tank and the fermentation tank are connected by a communicating vessel.

[0013] As a further improvement to this technical solution, the fermenter is fixed to the outside of a mounting frame, the bottom of which is in contact with the ground, and the collection tank is located on the upper side of the bottom of the mounting frame.

[0014] As a further improvement to this technical solution, the communicating vessel includes an inclined tube, an upper connecting pipe fixed on the side wall of the inclined tube, the upper connecting pipe being connected to the bottom pipe of the fermentation tank, and the lower end of the inclined tube being connected to the top of the collection tank.

[0015] The upper end of the inclined tube is sealed by a sealing plate, and an electric push rod is fixedly installed on the sealing plate. One end of the piston rod on the electric push rod passes through the sealing plate and is fixedly installed with a piston can. The piston can slides in contact with the inner wall of the inclined tube, and several rubber sealing rings are installed on the outer wall of the piston can. When the piston can moves, it seals the connection between the upper connecting pipe and the inclined tube.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. In the integrated ecological toilet water circulation system of this container module, the sediment and liquid are separated by a solid-liquid separation unit. Then, the liquid is treated by an integrated water treatment unit, a disinfection unit, and a recycled clean water tank, turning the liquid into usable greywater. This reduces the device's dependence on external water sources, improves its normal use in areas without water supply, and enhances its applicability in different environments. At the same time, the sediment is fermented by a high-temperature aerobic fermentation unit and collected, allowing the sediment to be utilized and achieving energy recycling.

[0017] 2. In the integrated ecological toilet water circulation system of this container module, the flow between the fermentation tank and the collection tank is controlled by a connecting device. This allows the fermentation tank to effectively ferment the sediment, and the sediment is collected in the collection tank after fermentation, thus separating fermentation and collection. When the collection tank is full, the piston tank pushes the remaining sediment inside the inclined tube into the collection tank, eliminating the problem of sediment leakage during disassembly and achieving a clean replacement of the collection tank.

Example

[0022] Please see Figures 1-5 As shown, this embodiment provides a water recycling system for an integrated ecological toilet using a container module, including a container 1. The container 1 adopts standard container dimensions, which is convenient for transportation and hoisting by truck, ship, or train. The interior of the container 1 is divided into three chambers by two partitions. The three chambers are a working chamber and a toilet located on both sides. Doors connecting to the outside are installed on the side walls of both the toilet and the working chamber. Users enter the toilet through the toilet door, and staff enter the interior of the working chamber through the working chamber door.

[0023] A vacuum rear-exit toilet 2 and a negative pressure collection unit 3 are installed in the bathroom. The negative pressure collection unit 3 absorbs the gas in the bathroom. The negative pressure collection unit 3 is mainly composed of a negative pressure fan and an exhaust pipe. The negative pressure fan absorbs the gas in the bathroom, so that the gas in the bathroom can be quickly renewed. The absorbed gas is introduced into the working chamber. A spray tower and an activated carbon adsorption box are installed in the working chamber. The spray tower and activated carbon adsorption box filter the gas to ensure that the discharged gas is odorless. Floor drains 11 are installed at the bottom of both the working chamber and the bathroom. The floor drains 11 can collect liquids on the ground in the bathroom and the working chamber.

[0024] The working chamber is equipped with a solid-liquid separation unit 4, an integrated water treatment unit 5, a high-temperature aerobic fermentation unit 6, a disinfection unit 7, and a recycled clean water tank 8. The discharge port of the vacuum rear-discharge toilet 2 is connected to the solid-liquid separation unit 4 through a pipe. The solid-liquid separation unit 4 can be a small screw extrusion solid-liquid separator, which has the advantages of small size and easy installation. The liquid separated in the solid-liquid separation unit 4 is transferred to the integrated water treatment unit 5 through a pipe. The integrated water treatment unit 5 performs integrated treatment on the liquid and then sends the treated liquid to the disinfection unit 7. The disinfection unit 7 disinfects the treated liquid and then sends it to the recycled clean water tank 8. The recycled clean water tank 8 is connected to the inlet pipe of the vacuum rear-discharge toilet 2 through a pipe. A submersible pump is installed in the recycled clean water tank 8, which pumps liquid into the vacuum rear-discharge toilet 2.

[0025] The integrated water treatment unit 5 consists of an equalization tank, an MBR (membrane bioreactor), and a disinfection filter tank. The disinfection unit 7 uses a sodium hypochlorite generator to disinfect the liquid transmitted from the integrated water treatment unit 5, bringing the liquid to a usable level for recycled water and ensuring the hygiene and safety of the recycled water.

[0026] The precipitate separated in the solid-liquid separation unit 4 is transported through pipelines to the high-temperature aerobic fermentation unit 6, where the precipitate is fermented and the liquid produced during fermentation is transported to the integrated water treatment unit 5.

[0027] By separating the precipitate and liquid using the solid-liquid separation unit 4, and then treating the liquid with the help of the integrated water treatment unit 5, disinfection unit 7, and recycled clean water tank 8, the liquid is treated into usable greywater, reducing the device's dependence on external water sources, improving its normal use in areas without water supply, and enhancing its applicability in different environments. At the same time, the precipitate is fermented by the high-temperature aerobic fermentation unit 6 and collected, allowing the precipitate to be utilized and achieving energy recycling.

[0028] The high-temperature aerobic fermentation unit 6 includes a fermentation tank 61. The precipitate in the solid-liquid separation unit 4 enters the interior of the fermentation tank 61 through the top of the fermentation tank 61. The fermentation tank 61 is used to ferment the precipitate. An electric heating device 12 is installed on the fermentation tank 61 to heat the precipitate inside the fermentation tank 61. An agitator is installed inside the fermentation tank 61. The agitator includes a rotating stirring rod installed in the fermentation tank 61 and a drive motor installed on one side of the fermentation tank 61. The drive motor drives the stirring rod to rotate, and the rotating stirring rod stirs the precipitate. The precipitate inside the fermentation tank 61 is heated by the electric heating device 12 to keep the internal temperature of the fermentation tank 61 at 60℃-70℃. The agitator is then used to stir the precipitate. Microorganisms rapidly degrade organic matter and kill pathogens at 60℃-70℃, ultimately producing an odorless and hygienic organic fertilizer base.

[0029] A collection tank 62 is installed on the lower side of the fermentation tank 61. A fixing frame 64 is fixed to the outside of the fermentation tank 61, with the bottom of the fixing frame 64 in contact with the ground. The fixing frame 64 supports the position of the fermentation tank 61, ensuring the stability of the fermentation tank 61 during use. The collection tank 62 is located on the upper side of the bottom of the fixing frame 64. The collection tank 62 collects the sediment after fermentation. The collection tank 62 and the fermentation tank 61 are connected by a communicating vessel 63. The communicating vessel 63 includes an inclined tube 631. A vertically upward connecting pipe 632 is fixed to the side wall of the inclined tube 631. The upper connecting pipe 632 is connected to the bottom pipe of the fermentation tank 61. The lower end of the inclined tube 631 is connected to the top of the collection tank 62. The upper end of 1 is sealed by a sealing plate 634, and an electric push rod 635 is fixedly installed on the sealing plate 634. One end of the piston rod on the electric push rod 635 passes through the sealing plate 634 and is fixedly installed with a piston can 633. The piston can 633 and the inner wall of the inclined tube 631 are in sliding contact, and several rubber sealing rings are installed on the outer wall of the piston can 633. The rubber sealing rings can improve the tightness of the contact between the piston can 633 and the inclined tube 631. When the piston can 633 moves to the position where the inclined tube 631 and the upper connecting pipe 632 are connected, it can seal the position where the inclined tube 631 and the upper connecting pipe 632 are connected. When the piston can 633 moves, it seals the position where the upper connecting pipe 632 and the inclined tube 631 are connected.

[0030] The communication device 63 controls the flow between the fermentation tank 61 and the collection tank 62, allowing the fermentation tank 61 to effectively ferment the sediment. After fermentation, the sediment is collected in the collection tank 62, achieving separation of fermentation and collection. When the collection tank 62 is full, the piston tank 633 pushes the sediment remaining inside the inclined tube 631 into the collection tank 62, eliminating the problem of sediment leakage during disassembly and achieving a clean replacement of the collection tank 62.

[0031] When fermentation tank 61 needs to ferment the sediment, piston tank 633 is pushed by the piston rod of electric push rod 635, causing piston tank 633 to seal the connection between inclined tube 631 and upper connecting pipe 632. At this time, the sediment in fermentation tank 61 cannot enter collection tank 62 through communicating vessel 63, thus ensuring the normal fermentation of sediment in fermentation tank 61. At the same time, when collection tank 62 is full of sediment, the worker needs to disassemble the connection between collection tank 62 and inclined tube 631. At this time, piston tank 633 continues to move to the lower end of inclined tube 631, so that piston tank 633 pushes all the remaining sediment in inclined tube 631 into collection tank 62. When collection tank 62 is replaced, no sediment will fall out, ensuring the cleanliness of the worker when replacing collection tank 62.

[0032] Meanwhile, a power distribution box 9 is installed inside the workshop. The power distribution box 9 is equipped with several circuit switches, which control the power supply of all electrical appliances inside the device. At the same time, solar photovoltaic panels are installed on the top of the container 1 to collect electricity, achieve energy self-sufficiency, and extend the off-grid usage time.

[0033] This device can be transported and hoisted by truck, ship, or train, and can be quickly deployed to infrastructure construction camps, emergency medical care for disaster relief, temporary or semi-permanent sites for the cultural and tourism industry, supplements to urban public toilets, and military and field operation camps, without the need for civil engineering.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
