Description

Technical Field

[0001] The invention relates to a self-cleaning solid-liquid separation integrated toilet and application thereof, belonging to the technical field of environmental protection and energy saving. Background Art

[0002] In the market, the existing "waterless toilets" generally refer to toilets without water tanks. The working principle of this waterless toilet is to make full use of the water pressure of the city tap water and apply the principles of fluid mechanics to intelligently identify the amount of stool in the toilet pit, and then reasonably use the corresponding amount of water to flush, so that the flushing water volume and flushing kinetic energy are cleverly matched, and the water saving effect can reach more than 50%, so it is not really waterless. This "waterless toilet" should be called a "water-saving toilet", but it also consumes a lot of water.

[0003] In some rural and remote areas, there are still a large number of open-air toilets, the so-called "pits" or "dry toilets". These open-air toilets have no advantages other than being simple and convenient to build: they pollute the soil, pollute groundwater, are difficult to dispose of waste, and provide a very bad toilet experience... If these toilets are to be upgraded, the infrastructure may not be available. To build a normal water toilet, it is necessary to lay water pipes and sewer pipes, which requires a lot of funds. In addition, in remote areas, water shortages also exist, and "water-saving toilets" are still difficult to promote.

[0004] In the early days of space flight, the duration was short, and astronauts had to bring enough disposable feces collection bags. In space, the collection bag adopts the "bag-wrapping method" to deal with feces. The collection bag has an elastic band at the mouth, which is opened when in use to fix it to the open end of the toilet. A series of small holes are opened at the bottom of the inner wall of the toilet liner. When in use, air is pumped through the exhaust pipe connected to the outer cylinder to form a certain negative pressure. When the collection bag is removed after use, the bag holes are automatically tightened. The collection bag containing waste is placed in the outer packaging bag and then put into a specific waste bin.

[0005] In Manned Spacecraft Technology (Qi Faren, National Defense Industry Press, 1999), Figure 5-15 on P134 is a "Schematic diagram of the internal structure of the space shuttle combined toilet", which adopts a two-way receiver structure. One is for air, urine and flushing water; the other is for air flow and solid waste. Many aspects of the latter are specially designed for space microgravity, and the structure used is extremely complex and not suitable for ground use. For example: (a) The solid-state receiver adopts an "ellipsoidal shape" structure, which is complex to manufacture and process and has a very high cost. (b) The lower center part adopts a "motor-driven thrower" mechanism, and the thrower adopts a series of "hinged" blades that expand outward to cut solid waste and deposit it into the "sandwich" of the inner wall of the toilet. The structure of the "sandwich" is complex; the thrower adopts a "hinged method" to connect the turntable with the blades, which is complicated to manufacture; the hinged blades in the figure use a nearly "parallelogram" and hinged needle knife with "end hooks", which is not conducive to cutting and discharging solid waste with a certain viscosity at a lower motor ground speed; the edge of the turntable is straight. If the turntable does not rotate and liquid waste reaches the edge, the liquid waste will flow inward toward the motor shaft.

[0006] In the "environmentally friendly waterless toilet" (CN107802200A), a "liquid buffer tank" and a "solid treatment cylinder" receiver structure are used, and a motor rotating cutting and crushing device is installed inside. This structure lacks an odor removal device. The patent states that "a one-way valve or a one-way valve can effectively prevent the occurrence of the reverse odor phenomenon." This can only prevent "reverse odor" but cannot achieve "no odor." (b) The cavity structure shape is relatively complex, there are too many inner and outer jackets of the same cross-section, and the number of cavities is relatively large (such as 3, 4, 13, 14, 15, 16, etc.). The cavity wall has cylindrical, conical, and irregular curved shapes. (c) The solid treatment cylinder adopts a drying and heating method with an electric heating wire wrapped around the outer side. The thermal inertia is large, and the heat capacity of the cylinder wall needs to absorb a large amount of heat first. The solid waste is only heated by heat conduction. After all, the solid waste in contact with the inner wall of the cylinder occupies a very small area ratio, and the heating and drying efficiency of the solid waste is low. (d) A "vertical connecting plate" is provided between the outer separation cylinder and the inner separation disc, which has a complex structure, is difficult to weld, and has high cost. (e) Not only is there a motor cutting device, but also a "solid discharge pump". The cost of the "solid discharge pump" accounts for a large proportion, and its inlet and outlet interfaces require a certain amount of space and interface design, which further increases the complexity and cost. (f) Temperature sensors and humidity sensors are used to control the start and stop of the "heating device" and "crushing motor" through the measured temperature, humidity values ​​and corresponding "preset thresholds". The control is complex and the reliability is poor. When the ambient temperature changes, the "preset threshold" needs to be set again, which is inconvenient. (g) It is only suitable for seat toilets, not for squatting positions. (h) The toilet can only dry and process waste, and a "storage for solid waste and liquid waste" needs to be set up outside. (i) It is difficult to disassemble and assemble, and the maintenance cost is high.

[0007] The "waterless toilet" (CN104127151B) uses a urine treatment system, a feces crushing part and a drying part. The defects of this waterless toilet are as follows: (a) By "evaporating the liquid in urine and feces at high temperature", because the water content in urine accounts for the majority, this method will consume a lot of heat and electricity. (b) The crushing and conveying devices are too complicated, difficult to manufacture and high in cost. For example, the "crushing chamber" includes "crushing cavity, wheel axle, motor"; the "conveyor" includes "conveyor cavity, first turbine, second turbine, second transmission shaft, third transmission shaft and transmission motor". (c) The "infrared sensor and data processor" are used to sense the distance between the human body and the toilet, which is only suitable for high-end seat toilets and is costly. (d) The "negative ion sodium hypochlorite generator" is used for sterilization, and the liquid needs to be added regularly. On the one hand, the waste generated has the result of chemical addition; on the other hand, there are many maintenance steps and the maintenance cost is high. (e) In terms of drive, "drive motor" and "drying motor" are used. Because the motor cost accounts for a considerable proportion of the manufacturing cost, adding a motor increases the cost. (f) Too many gears and turbines are used. Their processing is complex, with high precision requirements and great difficulty. In addition, their large number increases the cost significantly. For example, there are “drive gear 15”, “rack 17”, “second gear 28”, “first gear 29”, “drying gear 27”, “crushing gear 38”, “defecation gear 40”, “first turbine 18”, “second turbine 19”, “synchronous pulley 22”, etc., which must also have corresponding shafts and matching connections.

[0008] The "Solid Waste Rapid Decomposition Treatment Device" (CN1974967A) uses the "vacuum, microwave" drying treatment method to process solid waste into sterile and odorless "dry slices". The analysis is as follows. (a) The "vacuum" method requires additional vacuum equipment, which requires a large investment; additional processing time is required to pump air to form a vacuum chamber, and the processing time is delayed. (b) There are too many microwave magnetrons and processing chambers. For example, at least three chambers have multiple sets of magnetrons and lamps. (c) There are also too many pumps and motors, such as "solid-liquid separation 2", "spiral 7", "sewage 8", "water 12", "motor 36", "vacuum 22", etc., which are costly. (d) The structure is complex, disassembly and assembly are inconvenient, and the cleaning and maintenance costs are high.

[0009] In the "waterless toilet" (CN201414748Y), "hot air blower, dehumidifier and synchronous heater" are used to achieve "pure solid waste treatment", which is analyzed as follows. (a) This utility model only has a "feces bowl" and no "liquid waste outlet and storage", so it requires toilet users to only "defecate" but not "defecate", which is unrealistic because the system cannot dry urine after entering the "feces bowl". (b) For the solid waste that "protrudes" in the "feces bowl", a horizontally moving "vertical sheet scraper" is used to "scrape it flat", which requires an additional motor drive, has a complex structure and high cost. (c) There are also many electrical appliances, such as "hot air blower 8", "dehumidifier 11", "exhaust fan 15", "large exhaust fan 18", "small exhaust fan 19", "heater 12", "electric scraper 20", etc., and the large number of components will inevitably lead to high costs. (d) There are many interfaces between the electric drive air duct and the outside world, with 2-3. Summary of the invention

[0031] Compared with the prior art, the present invention has the following beneficial effects:

[0032] (1) The self-cleaning solid-liquid separation integrated toilet provided by the present invention is composed of a storage processor, a liquid storage device, a solid storage device, a cleaning device and a shell. The toilet has an ingenious structural design. The storage processor includes a storage extrusion device and a heating device. The toilet is convenient for solid-liquid separation in excrement, can achieve relatively fast drying and molding of solid waste, regularly produce solid and liquid organic fertilizers, and has a self-cleaning function, realizing an integrated design of toilet functions. At the same time, it uses the pneumatic heat principle to achieve no odor, and the toilet user has a good experience. The toilet has a simple structure, low cost, high efficiency, low cost of construction or renovation, low power consumption, and low water consumption.

[0033] (2) The storage processor of the present invention is preferably designed to be a "Y"-shaped groove structure. The bottom of the "Y"-shaped groove can receive solid waste and liquid waste simultaneously or separately. The received liquid waste enters the liquid storage container through the gap at the bottom of the "Y"-shaped groove and the guide plate at the bottom of the "Y". The heating device arranged on the outside of the fixed plate and the rotating plate can dry the stored solids. After the surface of the solid waste is partially dehydrated, the solid waste is clamped into sheets by rotating the "Y"-shaped groove rotating plate and enters the solid storage container to complete a cycle. The toilet of the present invention facilitates the separation of solid and liquid in excrement, regularly produces solid and liquid organic fertilizers, and realizes the integrated design of toilet functions.

[0034] (3) In the storage and extrusion device of the present invention, only the rotating plate can rotate, and the movable parts are reduced to a minimum, which is more simple. In addition, the fixed plate of the Y"-shaped groove and the back of the rotating plate are both provided with an electric heating film or an electric heating sheet, and a heat insulation layer is attached behind the electric heating film or the electric heating sheet, which has small thermal inertia, is lighter and thinner, and maximizes the baking area, improves the drying efficiency, and reduces the baking time.

[0035] (4) The present invention preferably provides cylindrical arc-shaped cover plates above and below the rotating plate of the storage and extrusion device. When the rotating plate rotates, the upper part of the clamped solids is closed and the opening of the lower solid storage container is opened to receive the solids. The odor of the dried solids is greatly reduced. The odor source is sealed by the upper double covers and the upper cover is closed after reaching the solid storage container, which is well isolated and controlled, and the odor is well controlled.

[0036] (5) The exhaust efficiency of the fan of the present invention is high. The exhaust port is deep in the vicinity of the seal of the liquid waste and solid waste processor. The odor source is controlled, the exhaust volume does not need to be large, the exhaust fan power is very small, and the exhaust efficiency is high. In addition, it is preferred to set a vertical plate on the upper part of the fixed plate and the rotating plate of the storage extrusion device. The vertical plate increases the distance between the user's buttocks and the receiver, which provides a good user experience. A spray pipe is arranged in the upper corner of the vertical plate. A push rod is arranged at the lower position of a vertical plate. The push rod and the opening of the upper cover can be designed to be farther apart. The structure is compact and multi-functional.

[0037] (6) The present invention is provided with a self-cleaning device, which can be used to clean the toilet after one or more uses, using very little water, thus achieving an absolute "environmentally friendly toilet".

[0038] (7) The toilet of the present invention can be designed and constructed underground, or the support and placement space structure can be constructed on the ground. The cost of construction or renovation is low, and it is easy to maintain and promote. In addition, the toilet of the present invention has a wide range of applications and can be used in rural and remote areas, outer space, cities, parks, and scenic spots. Moreover, the toilet can be connected to squatting equipment and seating equipment on the outside for use. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments:

[0043] like Figure 1 The figure shows the schematic diagram of the structure of the self-cleaning solid-liquid separation integrated toilet of the present invention. It can be seen from the figure that the solid-liquid separation integrated toilet of the present invention includes a storage processor, a liquid reservoir 23, a solid reservoir 18, a cleaning device, an exhaust device and a shell 30, wherein the storage processor, the liquid reservoir 23, the solid reservoir 18 and the cleaning device, the exhaust device are arranged inside the shell 30, and a side door 22 is provided on the shell 30 to facilitate the installation and removal of each component.

Each component can be designed under the ground or on the ground. For example, a support and retrieval space structure can be built on the ground, wherein the storage processor is relatively fixed to the ground, and the solid reservoir 22 and the liquid reservoir 23 are movable, so as to conveniently collect, take out, and put in. The self-cleaning solid-liquid separation integrated anti-fouling toilet of the present invention is a squatting device, and can also include a seat device connected to the processor for people to use the toilet. An upper cover 9 is provided on the top of the processor storage container, which is located at the upper part of the processor storage opening and cooperates with the shell 30 to form a closed structure.

[0044] like Figure 1As shown, the receiving and squeezing device of the present invention comprises a fixed plate 1, a rotating plate 2, and a blocking device, wherein the width of the rotating plate 2 is greater than the width of the fixed plate 1, and preferably the width of the rotating plate 2 is 1.1-1.20 times the width of the fixed plate 1. The wide plate of the Y-shaped groove structure naturally forms a guide plate to allow the incoming liquid to enter the liquid receiving groove 24.

[0045] The bottom of the fixed plate 1 contacts the side wall of the rotating plate 2 to form an open structure for receiving excrement. In an optional embodiment of the present invention, the fixed plate 1 and the rotating plate 2 form a Y-shaped structure, and a gap is formed at the contact part of the fixed plate 1 and the rotating plate 2, so that the liquid in the excrement enters the liquid collecting tank 27 through the gap, preventing the toilet user from being splashed and facilitating the discharge of liquid. In an optional embodiment of the present invention, a sawtooth is provided at the bottom of the fixed plate, and the liquid in the excrement enters the liquid collecting tank 24 through the multiple tooth gaps formed by the sawtooth tooth top and the rotating plate. Alternatively, end plates are respectively provided at both ends of the fixed plate 1 and the rotating plate 2, and a through hole connected to a liquid guide tube is provided on the end plate, and the liquid in the excrement is introduced into the liquid collecting tank 24 by the liquid guide tube. The through hole can be a circular hole or a triangular hole. In addition, two methods can be used at the same time: a small gap is formed at the contact part of the fixed plate 1 and the rotating plate 2 to introduce the liquid into the liquid collecting tank, and the liquid is introduced into the liquid collecting tank through the through hole on the end plate, thereby reducing the contact area between the liquid and the solid wall and the air, thereby reducing the source of liquid odor.

[0046] like Figure 3 The figure shows the schematic diagram of the structure of the plugging device of the present invention, wherein Figure 3 a is a diagram of the support rod structure. Figure 3 b is a diagram of the support plate structure. The rotating plate 2 is connected to the plugging device, which includes a plugging cover 17 and a support structure. The plugging cover 17 is a curved surface structure that matches the shape and edge of the storage container opening. In an optional embodiment of the present invention, the curved surface structure of the plugging cover 17 is a part of the cylindrical side wall. The plugging cover 17 is connected to the rotating plate 2 through support structures respectively arranged at both ends. The support structure is a support rod 18 or a support plate 21, such as Figure 3 A shows a diagram of the support rod 18. Figure 3 b shows a diagram of the sector-shaped support plate 21.

[0047] Before the receiving and squeezing device squeezes the solids in the excrement, the plugging cover 17 in the blocking device is located at the upper part of the opening of the solid storage 22 to seal the solid storage 22. After squeezing, the plugging cover 17 moves away from the upper opening of the solid storage 22 along with the rotating plate 2, and the sheet-like objects after squeezing and drying are pushed into the solid storage 22. A spring piece 19 is also provided at the opening of the solid storage 22. The spring piece 19 can be designed as a cantilever elastic steel wire with a certain strength, which is used to evenly distribute the solid waste entering the solid storage in the solid storage.

[0048] In an optional embodiment of the present invention, the heating device is an electric heating film 4 or an electric heating sheet 4, and the heating temperature of the heating device is 200℃~400℃. It is fixed on the surface of the fixed plate 1 and the rotating plate 2 where no solid extrusion is performed, and an insulation layer 5 is arranged outside the electric heating film 4 or the electric heating sheet 4. The insulation layer can be a skeleton insulation layer, and the insulation layer is fixed to the plate by screws, and the screws are embedded in but not through the wall. This design has small thermal inertia, is lighter and thinner, maximizes the baking area, improves the drying efficiency, and reduces the baking time.

The cover 10 is a curved structure, one side of which is connected to one end of the second vertical plate 33, and the other side is connected to the rotating plate 2 through the support rod 7. The cover 10 is used to block the opening of the storage extrusion transposition during solid extrusion. The two vertical plates are respectively located on the two long sides of the opening of the upper end surface of the shell. In an optional embodiment of the present invention, the two vertical plates are perpendicular to the mounting surface. In addition, a rotating shaft 3 is provided on the support rod 7, and the rotating plate 2 can rotate around the rotating shaft 3.

[0051] The cleaning device includes a water tank 20, a water pump 21, a water pipe 12, a valve 14 and a spray pipe 8. The water pump 21 is arranged inside the water tank 20. One end of the water pipe 12 is connected to the water pump 21 and the other end is connected to the spray pipe 8. When the valve is opened and the power is turned on, the water pump 21 works to send the water in the water tank 20 into the spray pipe 8 through the water pipe 12, and the spray pipe 8 cleans the inner wall surface of the storage and extrusion device. The spray pipe 8 is introduced into the cavity formed by the two vertical plates and the fixed plate 1 and the rotating plate 2 through the water pipe 12. The valve 14 is a solenoid valve, which is arranged on the water pipe. Its opening and closing control is synchronized with the water pump. The valve 14 is fixed to the housing 30 through the fixing rod 15.

[0052] like Figure 2The figure shows a schematic diagram of the liquid collecting tank structure of the present invention. It can be seen from the figure that the liquid collecting tank 24 of the present invention is arranged below the rotating plate 2 to receive liquid in the excrement, and the liquid storage tank 23 is arranged below the liquid collecting tank 24. The liquid collecting tank 24 includes a liquid collecting vertical plate 34, a liquid collecting side plate 38, a front blocking plate 35 and a rear blocking plate 36.

This structural design is more conducive to receiving and drawing out liquid.

The odor source is controlled, the exhaust volume does not need to be large, the exhaust fan power is very small, and the exhaust efficiency is high.

[0054] In an optional embodiment of the present invention, the solid storage container 18 and the liquid storage container 23 are preferably both transparent cavity structures, which are easy to observe and help control maintenance time.

[0055] The self-cleaning solid-liquid separation integrated toilet of the present invention has the following characteristics:

[0056] (1) Only one of the two plates of the "Y"-shaped groove rotates, and the number of moving parts is reduced to a minimum, which is simpler. The "Y"-shaped groove has a novel and unique structure, and the two plates are convenient for squeezing solids in excrement.

[0057] (2) The back of the two plates of the "Y"-shaped groove are both attached with heating film or heating plate, and then an insulation layer is attached behind the heating film or heating plate, which has small thermal inertia and is lighter and thinner.

[0058] (3) Storage volume: The clamping thickness of the storage clamping device can be achieved by changing the position of the shaft. The thickness of the clamping structure can be adjusted, and different design thicknesses can achieve changes in the peak solid content received at one time.

[0059] (4) High deliquescence efficiency of solid waste. After the "Y"-shaped groove receives the solid waste, it is clamped by turning the relevant handle rod, and both side plates are heated, which maximizes the baking area, improves the drying efficiency, and reduces the baking time.

[0060] (5) The two plates of the "Y"-shaped groove are in contact at the bottom, and there is no need to drill holes for drainage. The trace amount of liquid that seeps through the small gap is collected by the liquid collection tank installed at the bottom of the long plate tip and enters the liquid reservoir through the small hole at the bottom. The contact area between the liquid and the solid wall and the air is reduced, thereby reducing the source of liquid odor.

[0061] (6) Triangular holes can be provided at the bottom of the two end plates of the two plates of the "Y"-shaped groove, and the outer sides are respectively introduced into the liquid storage device through round pipes, which further reduces the source of liquid odor.

[0062] (7) The rotating plates in the two plates of the "Y"-shaped groove are provided with cylindrical arc-shaped cover plates above and below. When the rotating plates rotate to clamp the cake, the upper part of the clamped solids is closed and the opening of the lower solid storage container is opened to store the solid excrement.

[0063] (8) The odor is greatly reduced after the solid is squeezed and dried; the odor source is sealed by the upper double cover, and the upper cover is closed after entering the solid storage container, which is well isolated and controlled.

[0064] (9) The fan has high exhaust efficiency. The exhaust port is located near the seal of the liquid waste and solid waste processor, the odor source is controlled, the exhaust volume does not need to be large, the exhaust fan power is small, and the exhaust efficiency is high.

[0065] (10) A vertical plate is arranged on the upper part of the two plates of the "Y"-shaped groove. The vertical plate increases the distance between the buttocks of the toilet user and the storage position, thereby preventing the buttocks from being splashed; a rectangular spray pipe is arranged in the upper corner of the vertical plate; a push rod is arranged at the lower part of a vertical plate. The vertical plate allows the push rod and the opening of the upper cover to be designed to be farther apart, resulting in a compact structure and realizing multiple functions.

[0066] (11) After the upper part of the two transfer plates of the "Y"-shaped groove makes room for the driving rod, the edges are locked together to seal the solid odor to the greatest extent possible in the upper part of the extrusion space.

[0067] (12) The air intake of the exhaust duct is close to the odor source (liquid collection tank and baking cover) and is better controlled.

[0068] (13) Low construction or renovation cost and low maintenance cost.

[0069] (14) Ergonomic design, easy to maintain and promote.

[0070] The present invention first determines whether it is indoor or outdoor (such as dry toilet transformation) according to the geographical environment, and determines whether to use squatting or seat toilets; if squatting is selected, the upper part of the Y-shaped opening shell can be coupled with the foot surface; if a seat toilet is selected, the upper part needs to be coupled with a conventional seat toilet. After determining whether the toilet is installed on the upper part or the lower part of the ground, and completing the basic engineering of the location, quantity and positioning facilities of other toilets, the following implementation steps of the present invention are carried out.

[0071] (1) Press Figure 1 The Y-shaped slot, shaft and surrounding components are connected as shown, and the components in the storage processor are to be installed.

[0072] (2) Place the liquid reservoir, solid reservoir, and water tank into place through the side door.

[0073] (3) Put a V-shaped wax pad paper of appropriate size into the Y-shaped groove. After the person uses the toilet, the storage and extrusion device and the heating device work simultaneously. After a certain period of extrusion and baking, the push rod is pushed down along the surface of the fixed plate. After the two are reset, a cycle is completed.

[0074] (4) When the liquid storage tank and the solid storage tank are filled to a certain level separately or simultaneously, the fertilizer can be drawn out and cleaned out.

[0075] (5) During regular maintenance, simply start the flushing pump and clean the Y-groove with a small amount of water.

[0076] According to the control method of the present invention, within one use cycle, it is only necessary to close the corner of the rotating plate driving rod, start the electric switch, and bake the clamped solids. At the same time, the micro-exhaust is started, and the "time relay" controls a certain period of time until the solid cake reaches a certain degree of dehydration. The electric switch delay control completes a cycle. Push the cake pushing rod to allow the dried solid flakes to enter the solid storage device. Different solid flakes are basically evenly distributed in the solid storage device under the plucking of the spring. After the liquid storage device and the solid storage device collect a certain amount at the same time or separately, the storage can be moved to the required place, which is very convenient. After a certain period of time, it enters the necessary and simple maintenance link.

[0077] The self-cleaning solid-liquid separation integrated toilet of the present invention can be used in toilets in rural and remote areas, space toilets, urban toilets, park toilets or scenic spot toilets, etc.

[0078] The above description is only the best specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
