Description

Technical Field

[0001] The present invention relates to the technical field of toilets, and particularly to a toilet equipped with a classification and collection processing function.

Background Art

[0002] Currently, in large and small cities around the world, basically all waste such as feces and urine excreted by humans is treated by the mode of "cleaning toilet - pipe network collection - sewage treatment plant unified treatment". This mode has problems such as wasting water resources, having a high construction cost of sewage pipe networks, being prone to leakage due to damaged sewage pipe networks, being difficult to treat the remaining sludge, and being difficult to recycle and reuse nitrogen and phosphorus in urine and feces. Therefore, improvement is needed.

[0003] In domestic sewage, about 97% of the total nitrogen, 90% of the total phosphorus, and 60% of the COD come from urine and feces. Since the volume of urine and feces only accounts for about 1% of the domestic sewage volume, separating high - concentration, low - volume urine and feces from wash water and treating them separately can more easily achieve the purposes of reducing treatment costs and recovering resources. This has become one of the research focuses of domestic sewage treatment.

[0004] Regarding separating urine and feces at the source and treating them on - site, conventional general technologies include methods such as dry collection and storage of feces for regular treatment, dry collection and composting of feces for biodegradation, evaporation and crystallization of urine after oxidation stabilization or nitrification, biological treatment of black water (urine, feces, and anal wash water) in a flushing toilet, incineration - type toilet for feces, bio - electrochemical treatment and reuse of black water in a flushing toilet, membrane bioreactor treatment and reuse of black water in a flushing toilet, and nitrogen - gas - protected pyrolysis of feces. However, conventional urine and feces treatment technologies have problems such as insufficient recycling and reuse levels and unstable processes, and further improvement is needed.

[0027] The top plate of the relay box 5-11 can open on both sides along the central axis. After the top plate of the relay box 5-11 opens, an opening with a length and width of 15 cm × 15 cm is exposed at the middle position of the tip of the pyrolysis furnace 5-5. When a person defecates, the feces just fall from the opening. The top plate 5-6 of the pyrolysis furnace is the bottom plate of the relay box 5-11. The top plate 5-6 of the pyrolysis furnace can be completely opened to the upper four sides or completely closed, so that the collection tray 5-9 can pass through.

[0028] The lifting mechanism is used to drive the collection tray 5-9 to move up and down in the pyrolysis furnace 5-5 and the relay box 5-11. The role of the collection tray 5-9 is to receive the feces discharged when a person defecates and can enter the pyrolysis furnace 5-5 as a whole, so as to pyrolyze the received feces.

[0031] The feces pushing mechanism is installed in the relay box 5-11. Specifically, the feces pushing mechanism includes a first electric push rod and a first push plate 5-12. The first electric push rod is fixedly connected to the inner wall of the relay box 5-11. A material passing port is installed between the relay box 5-11 and the second storage box 5-10. The first electric push rod is used to drive the first push plate 5-12 to be slidably fitted with the inner wall of the collection tray 5-9 to push the carbonized feces in the collection tray 5-9 from the material passing port to the second storage box 5-10.

[0032] The tip of the heat recovery box is fixedly connected to the bottom end of the pyrolysis furnace 5-5. The bottom plate 5-7 of the pyrolysis furnace is the top plate of the heat recovery box. In this embodiment, a heating and temperature-raising component is installed on the inner wall of the bottom plate 5-7 of the pyrolysis furnace. The heating and temperature-raising component is used to provide heat for the pyrolysis of feces. The material of the bottom plate 5-7 of the pyrolysis furnace is stainless steel. Further below the bottom plate 5-7 of the pyrolysis furnace, a movable heat-insulating layer that can be opened and closed is installed. When the movable heat-insulating layer is closed, it fits against the outer wall of the bottom plate 5-7 of the pyrolysis furnace. When the movable heat-insulating layer is opened, a part of it is immersed in the liquid heat medium in the heat recovery box, thereby quickly transmitting the heat in the pyrolysis furnace 5-5 to the heat recovery box for recycling and reuse. The liquid heat medium is one or more of water, ethylene glycol, and heat transfer oil.

[0033] The liquid collection device includes a baffle 15, a urine collection pipe 11, a urine evaporation box 8, and an anal washing water discharge pipe 12. The baffle 15 is installed on the toilet body 3, and the baffle 15 divides the toilet bowl in the toilet body 3 into a urinal and a toilet bowl. A urine collection cavity 16 close to the urinal and an anal washing water collection cavity 17 close to the toilet bowl are installed in the baffle 15.

[0034] The urine evaporation box 8 is installed below the heat recovery device 6. The bottom plate of the heat recovery device 6 is the top plate of the urine evaporation box 8. An openable material passage port is installed on the box body of the urine evaporation box 8. The material passage port is used for adding evaporation drying aids to the urine evaporation box 8 and sorting the resource products in the urine evaporation box 8. The heat in the pyrolysis furnace 5-5 is conducted to the liquid heat medium in the heat recovery device 6 through the bottom plate 5-7 of the pyrolysis furnace and the movable heat insulation layer. The bottom plate 5-7 of the pyrolysis furnace adopts single-layer stainless steel to improve the heat conduction efficiency between the pyrolysis furnace 5-5 and the heat recovery device 6. The liquid heat medium dissipates heat to the urine evaporation box 8 through the bottom plate of the heat recovery device 6, thereby promoting the evaporation efficiency of urine in the urine evaporation box 8.

[0035] A first check valve 13 is installed on the urine collection pipe 11, and a second check valve 14 is installed on the anal cleansing water discharge pipe 12. The first check valve 13 and the second check valve 14 are used to prevent odors from flowing back into the toilet body 3 and the room.

[0036] The toilet with a classification collection and treatment function in this embodiment also includes an exhaust pipe 1. The urine evaporation box 8, the relay box 5-11, and the pyrolysis furnace 5-5 all communicate with the first end of the exhaust pipe 1. The exhaust pipe 1 passes through the pipe shaft of the toilet. The second end of the exhaust pipe 1 is installed outdoors (for example, on the roof of a building), and the second end of the exhaust pipe 1 is used for exhaust. The odors in the liquid evaporation box, the relay box 5-11, and the pyrolysis furnace 5-5 are discharged through the exhaust pipe 1. Specifically, the exhaust pipe 1 can adopt a DN50 pipe made of PVC material.

[0037] The toilet cover plate 9 is attached to the top of the toilet body 3. The toilet cover plate 9 is made of plastic, with a length, width, and thickness of 70 cm × 35 cm × 1.5 cm. A storage cavity is installed on the toilet cover plate 9 corresponding to the control panel 2. The control panel 2 is slidably fitted into the storage cavity, and a switch for controlling the opening and closing of the controller and each component (including the lifting mechanism, the first electric push rod, the second electric push rod, the first motor, the water spray pipe, and the cleaning pipe, etc.) is installed on the control panel 2.

[0038] In addition, the telescopic spray pipe adopted by the anal cleaning device 4, the top plate that can be opened on both sides along the central axis on the relay box 5-11, the top plate that can be fully opened or completely closed on the upper four sides of the pyrolysis furnace 5-5 (i.e., the top plate 5-6 of the pyrolysis furnace), and the movable heat preservation layer that can be opened and closed at the bottom end of the pyrolysis furnace 5-5 can be directly purchased from the market or realized by those skilled in the art based on the content described in this application. Moreover, the telescopic spray pipe adopted by the anal cleaning device 4, the top plate that can be opened on both sides along the central axis on the relay box 5-11, the top plate that can be fully opened or completely closed on the upper four sides of the pyrolysis furnace 5-5, and the movable heat preservation layer that can be opened and closed at the bottom end of the pyrolysis furnace 5-5 can all realize electronic control and are respectively signal-connected to the controller, and commands are sent to the controller through the control panel 2 to control the telescopic spray pipe adopted by the anal cleaning device 4, the top plate that can be opened on both sides along the central axis on the relay box 5-11, the top plate that can be fully opened or completely closed on the upper four sides of the pyrolysis furnace 5-5, and the movable heat preservation layer that can be opened and closed at the bottom end of the pyrolysis furnace 5-5 to perform corresponding operations.

[0039] In this embodiment, the control panel 2 adopts a touch screen made of liquid crystal material. The control panel 2 is signal-connected to the controller, and a preset program is set in the controller. The preset program can realize the automatic control of the operations of components such as the anal cleaning device, the feces collection and processor 5, the heat recovery device 6, the dehumidification device 7, the urine evaporation box 8, and the urine cleaning device 10. Moreover, four working control buttons, namely feces treatment preparation, feces treatment start, anal cleaning start, and urine treatment start, are installed on the control panel 2, and it can perform wireless communication connection with a mobile phone. When the control panel 2 is not taken out, operations can be directly realized through the app mini-program on the mobile phone program.

[0040] It is necessary to explain that functions such as the above-mentioned feces treatment preparation, feces treatment startup, anal cleaning startup, urine treatment startup, etc. are realized by a preset program in the controller. However, since the preset program is a program written by those skilled in the art with reference to conventional computer programming knowledge according to the content described in this application, in this embodiment, the preset program will not be further explained.

[0041] Also, the circumferential outer wall of the urine evaporation box 8, the circumferential outer wall of the heat recovery box, the side walls of the relay boxes 5-11, the top plates of the relay boxes 5-11, the top plate of the pyrolysis furnace 5-6, the side walls of the pyrolysis furnace 5-5, the side walls of the first storage box 5-3, the side walls of the second storage box 5-10, and the material feed door 5-4 all adopt heat insulation plates, which can achieve the temperature holding effect by adopting heat insulation plates and avoid waste caused by heat loss.

[0042] In the selectable solution means of this embodiment, more preferably, the heat insulation plate includes two layers of stainless steel plates and a polyurethane foam plastic layer sandwiched between the two layers of stainless steel plates.

[0043] The specific working principle of the toilet with the classification and collection treatment function in this embodiment is as follows: When the user defecates, the top plate of the relay box is opened through the control panel. The feces discharged by the user to the outside of the body fall into the collection tray from the opening opened by the top plate of the relay box 5-11 (shown in Figure 2). After the user discharges the feces to the outside of the body, press the feces treatment start button on the control panel 2, and the collection tray 5-9 descends to the bottom of the pyrolysis furnace 5-5 (shown in Figure 3). The top plate of the relay box 5-11 and the top plate of the pyrolysis furnace are closed simultaneously. Next, the material feeding door 5-4 is opened. Under the combined action of gravity and the thrust of the solid medium storage box push rod, etc., the solid heat medium 5-2 stored in the solid heat medium 5-2 storage box is pushed into the pyrolysis furnace 5-5 (refer to Figure 4). Next, the material feeding door 5-4 is closed, the solid medium storage box push rod contracts back to its original position, and the pyrolysis furnace 5-5 activates the heating and temperature-raising component arranged on the bottom surface of the pyrolysis furnace 5-5. After heating for a certain period, after the feces are fully pyrolyzed, they become carbonized feces (refer to Figure 5). Next, the cover plate of the pyrolysis furnace 5-5 is opened, and the collection tray 5-9 rises under the action of the slide rod. Under the action of gravity, the solid heat medium 5-2 falls from the hole of 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 of the pyrolysis furnace 5-6 is closed. At the same time, the material feeding door 5-4 is opened. Under the action of the second electric push rod, the solid heat medium 5-2 in the pyrolysis furnace 5-5 is pushed into the solid medium storage box by the second push plate 5-8. Then, the material feeding door 5-4 is closed, the push rod of the pyrolysis furnace 5-5 contracts back to its original position. After the collection tray 5-9 rises to the designated position (the designated position is the coaxial part of the axis of the collection tray 5-9 and the first push plate 5-12, refer to Figure 6), under the action of the first electric push rod, the carbonized feces are pushed into the second storage box 5-10 by the first push plate 5-12 (refer to Figure 7). Then, the carbonized feces collection push rod contracts back to its original position (refer to Figure 8), and the lower movable heat preservation layer at the bottom interface of the feces collection and processor 5 is opened. Thereby, the liquid heat medium in the heat recovery device 6 recovers the waste heat in the feces collection and processor 5, and at the same time, the feces treatment process is completed.

[0044] After the defecation user presses the feces treatment device button to perform the feces treatment function, the user can press the anal cleaning start button to clean the user's anus. After the anal cleaning water falls on the surface of the upper cover plate of the feces collection and processor 5, under the action of gravity, it flows into the anal cleaning water collection cavity 17 of the baffle 15 through the second liquid inlet hole 19, and then is injected into the municipal pipe network through the anal cleaning water discharge pipe 12 and sent to the municipal sewage treatment plant for treatment. At the same time, the second check valve 14 on the anal cleaning water discharge pipe 12 enables the anal cleaning water to be discharged in a single direction under the action of gravity, and at the same time, the odor in the pipeline does not flow backward into the toilet.

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

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

[0047] This embodiment adopts the technical solutions of the structure of the above device and its usage method, and can effectively process feces and urine on-site, realize resource utilization, simultaneously generate carbonized feces and urine crystals, and compared with the conventional mode of "washing with a flushing toilet, collecting through a sewage pipe network, and centrally treating at a sewage treatment plant" for handling excrement and urine, it reduces the treatment cost, realizes carbon isolation of organic waste, reduces carbon emissions, realizes the recovery of phosphorus resources in sewage, and at the same time reduces the toilet flushing water, saves water resources, and the economic benefits, ecological benefits, and social benefits are obvious.
