Description

[Technical field]

[0001] The present invention relates to the technical field of toilets, and more particularly to a toilet with classification, collection and processing functions. [Background technology]

[0002] At present, all large and small cities around the world basically use the "flush toilet - pipe network collection - unified treatment at sewage treatment plant" model to treat waste such as feces, urine and other human waste. However, this model has problems such as wasting water resources, high construction costs for sewage pipe networks, the tendency of sewage pipe networks to be damaged and leaking, difficulty in treating the remaining sludge, and difficulty in recycling and reusing the nitrogen and phosphorus in sewage and feces as resources, which need to be improved.

[0003] In domestic wastewater, approximately 97% of the total nitrogen, 90% of the total phosphorus, and 60% of the COD come from feces and urine, and the volume of feces and urine accounts for only about 1% of the volume of domestic wastewater. Therefore, if the high-concentration, low-volume feces and urine and wash water are separated and treated separately, it will be easier to reduce treatment costs and recover resources, and this has become one of the research focuses of domestic wastewater treatment.

[0004] Conventional technologies for separating feces and urine at the source and treating them on-site include dry collection, storage and periodic treatment of feces, dry collection and compost biodegradation of feces, oxidative stabilization of urine or evaporation crystallization after nitrification, biological treatment of black water from flushing toilets (feces and urine and anal wash water), feces incineration toilets, bioelectrochemical treatment and reuse of black water from flushing toilets, membrane bioreactor treatment and reuse of black water from flushing toilets, and nitrogen gas protected pyrolysis of feces. However, conventional feces and urine treatment technologies have problems such as insufficient resource recycling and reuse and unstable processes, and further improvement is required.

[0042] In the alternative solution of this embodiment, more preferably, the heat insulating board includes two layers of stainless steel board and a polyurethane foam plastic layer sandwiched between the two layers of stainless steel board.

[0043] The specific working principle of the toilet with classification, collection and processing function in this embodiment is as follows: When the user defecates, the top plate of the relay box is opened via the control panel, and the feces discharged by the user from the body falls into the collection tray through the opening opened by the top plate of the relay box 5-11 (see FIG. 2). After the user discharges the feces from the body, the user presses the feces processing start button on the control panel 2, and the collection tray 5-9 descends to the bottom of the pyrolysis furnace 5-5 (see FIG. 3). The top plate of the relay box 5-11 and the top plate 5-6 of the pyrolysis furnace close at the same time, and then the material feed door 5-4 opens, and the material is removed by gravity and solidification. Under the combined action of the thrust of the solid medium storage box push rod, etc., the solid heat medium 5-2 stored in the solid heat medium storage box is pushed into the pyrolysis furnace 5-5 (see Figure 4), then the material feed door 5-4 is closed, the solid medium storage box push rod is contracted back, and the pyrolysis furnace 5-5 starts the heating and heating parts located at the bottom of the pyrolysis furnace 5-5, and after heating for a certain period of time, the feces is fully pyrolyzed and becomes carbonized feces (see Figure 5), then the cover plate of the pyrolysis furnace 5-5 is opened, and the collection tray 5-9 is inserted into the slurries. Under the action of the second electric push rod, it rises, and under the action of gravity, the solid thermal medium 5-2 falls from the hole in the collection tray 5-9 into the pyrolysis furnace 5-5. After the collection tray 5-9 leaves the pyrolysis furnace 5-5, the top plate 5-6 of the pyrolysis furnace closes and opens the material feed door 5-4 at the same time. Under the action of the second electric push rod, the solid thermal medium 5-2 in the pyrolysis furnace 5-5 is pushed into the solid medium storage box by the second push plate 5-8, and then the material feed door 5-4 closes, the push rod of the pyrolysis furnace 5-5 shrinks back, and the collection tray 5-9 rises to the designated position. (The designated position is the coaxial position between the axis of the collecting tray 5-9 and the first pushing plate 5-12, see FIG. 6). Under the action of the first electric pushing rod, the carbonized feces is pushed by the first pushing plate 5-12 into the second storage box 5-10 (see FIG. 7), after which the carbonized feces collecting pushing rod contracts back (see FIG. 8), and the lower movable heat-insulating layer at the bottom interface of the feces collecting and processor 5 opens, so that the liquid heat medium in the heat recovery device 6 recovers the residual heat in the feces collecting and processor 5, and at the same time, the feces processing process is completed.

[0044] After the user defecates by pressing the stool processing device button to perform the stool processing function, he or she can press the anal cleansing start button to clean the user's anus. The anal cleansing water falls onto the surface of the upper cover plate of the stool collecting and processing device 5, and then flows into the anal cleansing water collecting cavity 17 of the baffle 15 through the second liquid inlet 19 under the action of gravity, and then flows into the municipal drainage network through the anal cleansing water discharge pipe 12, and is sent to the municipal sewage treatment plant for treatment. At the same time, the second check valve 14 on the anal cleansing water discharge pipe 12 allows the anal cleansing water to be discharged in one direction under the action of gravity, and at the same time, the odor in the pipe does not flow backwards into the toilet bowl.

[0045] After the defecation user discharges urine from the body, the urine treatment start button is pressed, and the urine cleaning device 10 sprays anal cleansing water to clean the urine. Under the action of gravity, the mixture of urine and cleansing water passes through the first liquid inlet 18 and flows into the urine collection cavity 16, and then passes through the urine collection tube 11 and is injected into the urine evaporation box 8 for evaporation treatment. The first check valve 13 on the urine collection tube 11 can prevent odorous overflow during the urine collection and evaporation process.

[0046] The start and end of the evaporation process in the urine evaporation box 8 is controlled by a sensor installed in the dehumidifier 7. When the gas humidity in the urine evaporation box 8 is higher than the saturated vapor pressure, the dehumidifier 7 is started to evaporate the urine and the anal wash water entering the device. During the evaporation process, the heat recovery device 6 heats the urine evaporation box 8 through the liquid heat medium and the thermal conduction effect of its bottom plate. When the gas humidity in the urine evaporation box 8 is lower than the saturated vapor pressure, the dehumidifier 7 stops working.

[0047] In this embodiment, by adopting the above-mentioned technical solutions of the device structure and its usage, feces and urine can be effectively treated on-site, and resource utilization can be realized. Carbonized feces and urine crystals are simultaneously produced. Compared with the traditional urinary and fecal matter treatment mode of "flushing with a flushing toilet, collecting in a sewage pipe network, and treating centrally at a sewage treatment plant", this embodiment reduces treatment costs, realizes carbon sequestration of organic waste, reduces carbon emissions, and realizes the recovery of phosphorus resources in wastewater. At the same time, the amount of toilet flushing water is reduced, and water resources are saved. The economic, ecological and social benefits are obvious.
