An excreta management system 100 according to an embodiment of the present invention is described below with reference to fig. 1 to 14.

The excreta management system 100 according to the embodiment of the present invention, as shown in fig. 3, 8 and 9, comprises: a toilet 4, a fecal treatment system 2, a reversing device 5 and a urine treatment system 3. The fecal management system 2 and the urine management system 3 are both disposed of in the fecal management system 103.

Wherein, as shown in fig. 9 and fig. 10, the toilet bowl 4 is provided with a stool outlet 4110 and a urine outlet 4120, when a person normally uses the toilet, the produced urine flows out from the urine outlet 4120, and the produced stool is discharged from the stool outlet 4110. The toilet stool 4 can separate urine and excrement without additionally installing a solid-liquid separation mechanism, has low cost and low after-sale maintenance rate, and is particularly convenient for subsequent excrement treatment.

As shown in fig. 8, the fecal treatment system 2 includes a plurality of fecal reactors 21, the inlets 212 of the plurality of fecal reactors 21 are connected to the fecal outlet 4110 through a multi-way tube 6, and a stirring shaft 22 is disposed in each fecal reactor 21 and is rotatable relative to the fecal reactor 21. Diverter device 5 is connected to manifold 6 to control communication of fecal outlet 4110 with inlet 212 of at least one of the plurality of fecal reactors 21.

Thus, one toilet bowl 4 can handle a plurality of treatment devices 103, and the amount of excrement to be treated can be increased. The direction changing device 5 is provided so that the feces outlet 4110 of the toilet bowl 4 is alternately connected to the plurality of feces reactors 21. Taking the two fecal reactors 21 of fig. 8 as an example, when the left fecal reactor 21a is full, the toilet 4 can be switched to connect to the right fecal reactor 21b, and the full left fecal reactor 21a remains blocked and no more receives new fecal material. During the period when the left fecal reactor 21a is blocked, the feces produced in the toilet 4 are discharged into the right fecal reactor 21 b. During this period, the left fecal reactor 21a continues to degrade under the influence of the internal reactants, which ensures that the fecal treatment time in the left fecal reactor 21a is not less than the lock-out period of the fecal reactor 21. Through the reasonable setting of two excrement reactors 21 rotation time, can guarantee that excrement and urine processing time is greater than the shortest required time in excrement and urine reactor 21 to guarantee that every excrement and urine reactor 21 all reaches good treatment to excrement and urine, the degradation completion rate is high.

Referring to fig. 9 and 7, the urine treatment system 3 includes a urine pretreatment tank 31 and a photochemical reactor 32 connected in series, and the urine pretreatment tank 31 is connected to a urine outlet 4120.

When the urine pretreatment device is used, the primary treatment agent is added into the urine pretreatment tank 31, and the discharged urine is purified into primary treatment liquid after being reacted by the primary treatment agent. For convenience of understanding, the liquid name after each stage of treatment of urine is analogized by the first stage treatment liquid, and if the treatment agent is added in the corresponding stage treatment, the name of the treatment agent corresponds to the treatment stage. For example, in photochemical reactor 32, the treatment agent is added as a secondary treatment agent, and the liquid produced after the purification in photochemical reactor 32 is a secondary treatment liquid.

Here, the type of the primary treatment agent is not particularly limited, and for example, the primary treatment agent may include a microbial agent that grows and proliferates using urine as a nutrient solution and converts ammonia nitrogen in urine into nitrate or nitrite that is easily absorbed by algae while eliminating the odor of urine. For another example, the primary treatment agent may include an adsorbent, which can absorb urea and other substances in urine to prevent the urine from producing an irritating odor. The adsorbent may be charcoal, and the adsorbent may also be activated carbon, molecular sieve, etc., and is not particularly limited herein.

The secondary treatment agent can be underwater plants such as algae, namely algae seeds are added into the photochemical reactor 32 for algae cultivation, and redundant algae can be discharged or reused after several growth cycles, for example, livestock and poultry feed is produced by using the algae, or the algae is processed into organic fertilizer and the like. The type of algae is not particularly limited, and examples of the algae include green algae, golden algae, diatom, blue algae, red algae, etc. of freshwater algae, and chlorella, scenedesmus obliquus, spirulina, etc. with high protein content.

Through the metabolism of algae, the oxygen-enriched components can be effectively reduced, and the requirement of national regulation on discharged water quality is met. For example, under photosynthesis, algae culture can absorb nitrogen, phosphorus, zinc, copper and other heavy metal elements in the primary treatment liquid, greatly reduce the Chemical Oxygen Demand (COD for short, Chemical Oxygen Demand for English) in urine, and eliminate the peculiar smell in the liquid. The first-stage treatment liquid is converted into a second-stage treatment liquid under the action of the photochemical reactor 32, and the second-stage treatment liquid can be reused or directly discharged.

According to the excrement disposal system 100 of the embodiment of the present invention, the toilet 4 having the excrement outlet 4110 and the urine outlet 4120 is provided, so that the produced excrement and urine can be separated and disposed, and the system is low in cost and low in maintenance rate. By providing the reversing device 5, the toilet bowl 4 can be connected to the plurality of fecal reactors 21 in a replaceable manner, and the amount of excrement to be treated can be increased. And the excrement reactor 21 can be kept in a sealed state after being filled, the treatment time is sufficient, and the excrement treatment completion rate is improved. By arranging the urine pretreatment tank 31 and the photochemical reactor 32, the COD of the discharged urine can be greatly reduced, and the generated liquid can be directly discharged or recycled, so that the environmental protection aims of low energy consumption, no pollution and high cleanliness are fulfilled.

In some embodiments, as shown in fig. 1-4, the excreta management system 100 further comprises a housing 101 and a reaction chamber 102 disposed under the housing 101, a urinal 410 is disposed in the housing 101, the fecal treatment system 2 and the urine pre-treatment tank 31 are disposed in the reaction chamber 102, and the photochemical reactor 32 is disposed on the roof 1012 or the outer wall 1011 of the housing 101. With such an integrated design, the excreta management system 100 can be transported and installed as a single product after being assembled, and is highly adaptable to the installation site during installation.

It can be understood that in special geographical environments such as mountains and canyons, the transportation of vehicles is difficult, the arrangement of the common toilet is time-consuming and labor-consuming, and the treatment of excrement in the later period is troublesome. In the embodiment of the present invention, the excrement disposal system 100 is designed to be an integrated structure, and the excrement disposal system 100 can be directly placed after being transported to a placement site for use, which is convenient to use and has strong practicability.

In addition, the treatment device 103 (the fecal treatment system 2 and the urine treatment system 3) is integrated on the lower part of the fecal treatment system 100 or the house body 101, the connecting pipeline in the system is short, and the later-stage inspection is convenient and easy to solve if the problems of leakage, pipe burst, pipe blockage and the like occur. For example, as shown in fig. 1 and fig. 9, the photochemical reactor 32 is disposed on the outer wall 1011 of the housing 101, the urine pretreatment tank 31 is connected to the photochemical reactor 32 through the conduit 35, and the conduit 35 extends directly upward from the reaction chamber 102 to connect to the photochemical reactor 32, and the conduit therebetween is short and clear in path.

Specifically, as shown in fig. 1 and 9, a door 1013 is provided on the house 101, and the door 1013 is used to open or close the house 101. In fig. 9, since the reaction chamber 102 is disposed below the chamber body 101, the chamber body 101 is higher than the floor, the door 1013 extends downward to the reaction chamber 102, and the excreta management system 100 is further provided with a step 1014, and the step 1014 connects the floor of the chamber body 101 to the door opening.

In some embodiments, as shown in fig. 12-14, the toilet bowl 4 includes a body 41, an upper surface of the body 41 is recessed downward to form a bowl 410, a bowl 411 and a urinal 412 are provided in the bowl 410, which are separated by a partition 42, a stool outlet 4110 is provided on a bottom wall of the bowl 411, and a urine outlet 4120 is provided on a bottom wall of the urinal 412.

Wherein, the urine collecting tank 412 is arranged at the front side of the urine collecting tank 411, when people normally go to the toilet, the urine is discharged to the front of the clapboard 42 to be collected in the urine collecting tank 412, and then flows out from the urine outlet 4120. The generated excrement is discharged to the partition plate 42, collected in the excrement collecting tank 411, and then discharged from the excrement outlet 4110.

In fig. 2-4, the toilet 4 is a toilet bowl, and a backrest 46 is provided at the rear side of the toilet 4, and a flush tank (not shown) may be provided in the backrest 46. The toilet bowl 4 further includes a cover 45, and the cover 45 is provided on the body 41 to open or close the bowl 410, thereby ensuring freshness and tastelessness in the room.

Advantageously, as shown in fig. 14, the bottom wall 4121 of the urine collection tank 412 is formed into a curved surface that is concave downward, and the urine outlet 4120 is provided at the lowest point of the bottom wall 4121 of the urine collection tank 412.

Alternatively, as shown in fig. 13 and 14, the urine outlet 4120 may be provided in a plurality of rows and columns to improve the appearance of the toilet 4, and the plurality of urine outlets 4120 may increase the urine outflow speed to prevent the urine from being accumulated in the urinal 410 to degrade the appearance. In fig. 13, the plurality of urine outlets 4120 are formed in two rows in the front-rear direction and four rows in the left-right direction.

Advantageously, as shown in fig. 14, the area of the stool outlet 4110 is equal to or greater than half the inlet area of the sump 411. The stool outlet 4110 is designed to be large, so that the discharged stool can be prevented from adhering to the side wall of the toilet bowl 411 as much as possible, the cleanliness of the toilet bowl 4 is maintained, and the use impression is improved.

Preferably, as shown in fig. 14, the faeces outlet 4110 extends completely through the bottom wall of the bowl 411, i.e. in the product of fig. 14 the bottom wall portion of the bowl 411 is removed from the toilet bowl 4. Further preferably, the collection bowl 411 is formed in a straight barrel structure, and an area of the stool outlet 4110 is equal to an inlet area of the collection bowl 411.

In some embodiments, as shown in fig. 4, the toilet bowl 4 further comprises a urine collection pot 43, the urine collection pot 43 being disposed below the urine collection basin 412 and communicating with the urine outlet 4120. Thus, urine generated by people going to the toilet flows into the urine collection pot 43 through the urine collection pool 412, and the urine collection pot 43 has a certain capacity and plays a role in temporary storage. And the urine flows into the urine collection pot 43 quickly, so that the diffusion of the pungent smell of the urine can be avoided.

In the example of fig. 2 and 4, the toilet 4 is a toilet bowl, the toilet 4 includes a toilet peripheral plate 47 extending downward along the outer periphery of the body 41, the toilet peripheral plate 47 is attached to the floor of the room 101, and the toilet peripheral plate 47 is provided to ensure the appearance of the toilet 4. The urine collection pot 43 is arranged in the outer surrounding plate 47 of the toilet bowl and is closed, so that the odor of the remaining urine can be prevented from diffusing.

Specifically, as shown in fig. 4, the urine collection pot 43 includes: a funnel 431 and a pot body 432, the funnel 431 is open at the top, the funnel 431 extends upwards and outwards from the top of the pot body 432, and the opening of the funnel 431 is arranged towards the urine outlet 4120. Thus, the urine collecting pot 43 has a simple structure, and can completely contain urine discharged from the urine collecting pool 412, thereby avoiding leakage of urine and facilitating cleaning.

Preferably, as shown in fig. 14, the cross-sectional area of the side wall of the urine collection basin 412 is reduced downward, that is, the urine collection basin 412 is formed in a downwardly contracted funnel shape, and the urine outlet 4120 is located at the lowermost end of the bottom wall 4121 of the urine collection basin 412, so that the urine discharged from the urine outlet 4120 is not easily discharged outwardly along the bottom wall 4121 of the urine collection basin 412.

Specifically, as shown in fig. 4, the area of the bottom wall 4121 of the urine collection basin 412 is smaller than or equal to the open area of the funnel 431, so that when the urine collection basin 412 is installed, the lowest end of the urine collection basin 412 can extend into the open port of the funnel 431, thereby further preventing the leakage of urine.

More specifically, as shown in fig. 4, a urine collection jug 43 is connected to the urine disposal system 3 by a urine pipe 44.

When the fecal treatment system 2 is in operation, the fecal reactor 21 contains a reagent. The reactant can be directly fed from the urinal 411 and enters the excrement reactor 21 through the multi-way pipe 6, and the operation is simple and convenient. The reactant may include microbial agents known in the art, and after the microorganisms grow and propagate in the fecal reactor 21, the microorganisms can degrade organic substances in the feces, so that the feces are decomposed and converted into organic fertilizers. Meanwhile, the growth of microbial thallus consumes the nutrients needed by pathogenic microorganisms in the excrement, inhibits the growth of the pathogenic microorganisms, and can kill pathogenic bacteria, worm eggs and the like in the excrement by decomposing, fermenting and generating heat. In addition, the odor substances generated by the excrement can be adsorbed, degraded and converted due to the generation of the microbial agent.

The fecal reactor 21 is designed as a closed cylinder due to stirring by the stirring shaft 22 inside the fecal reactor 21. Here, the fecal treatment system 2 treats only the feces produced in the toilet, and the moisture content in the feces is small.

Optionally, sawdust and bran can be included in the reaction agent, and the microbial agent is mixed into the sawdust and the bran. Sawdust and bran can be uniformly mixed into excrement by the rotation of the stirring shaft 22, so that the microbial agent is uniformly mixed, and the effect of quickly degrading the excrement is achieved. The addition of the sawdust and the bran and the rotation of the stirring shaft 22 can avoid partial excrement from caking and being incapable of degrading, and meanwhile, the sawdust and the bran can absorb liquid and odor to adsorb degradation products into clusters, and finally the degradation products can be rolled into spherical and ellipsoidal small blocks. Therefore, the fertilizer generated after the degradation is finished is very convenient to transport, and the cleaning and maintenance of a later system are facilitated.

In some embodiments, the stirring shafts 22 of the plurality of fecal reactors 21 are coaxially arranged and connected in series, i.e., the plurality of fecal reactors 21 are connected in series. Like this, only need drive one of them (mixing) shaft 22 and just can drive a plurality of (mixing) shafts 22 and rotate simultaneously, simplified system architecture, greatly reduced system cost makes the product fault rate reduce by a wide margin, does benefit to and reduces after-sale maintenance rate.

Of course, the present invention is not limited thereto, and a plurality of fecal reactors 21 may be coaxially arranged and connected in series such that each stirring shaft 22 is fixed and only one of the fecal reactors 21 is driven to simultaneously rotate the plurality of fecal reactors 21.

In some embodiments, as shown in fig. 3, the fecal management system 2 further comprises a driver 25, the driver 25 is connected to the agitation shafts 22 of the plurality of fecal reactors 21 to drive the agitation shafts 22 to rotate. Compared with the scheme of driving the excrement reactor 21 to rotate, the driving stirring shaft 22 has simpler and more labor-saving rotating structure and low energy consumption.

Specifically, as shown in fig. 3 and 8, the driver 25 is a motor 251, and the motor 251 is connected to the stirring shaft 22 through a reduction transmission device 26, so as to reduce the speed of the stirring shaft 22 and achieve the effects of reducing speed and increasing torque.

Alternatively, as shown in fig. 3 and 8, the reduction gear 26 includes a speed reducer 261, and the speed reducer 261 is connected between the motor 251 and the stirring shaft 22.

Alternatively, as shown in fig. 3 and 8, reduction drive 26 may include a belt drive assembly 262, belt drive assembly 262 being connected between motor 251 and agitator shaft 22. The belt driving assembly 262 includes a large driving wheel 2621, a small driving wheel 2622, and a conveying belt 2623. The belt transmission assembly 262 is used for speed reduction, the structure is simple, the transmission is stable, the belt transmission assembly 262 can buffer and absorb vibration due to the characteristic of belt transmission, the belt transmission assembly 262 is low in manufacturing cost, does not need lubrication and is easy to maintain.

In the example of fig. 3, the reduction gear 26 includes a speed reducer 261 and a belt transmission assembly 262, the speed reducer 261 is connected to a motor shaft, a small transmission wheel 2622 is connected to the speed reducer 261, a large transmission wheel 2621 is coaxially connected to the stirring shaft 22, and a conveyor belt 2623 is respectively engaged with the large transmission wheel 2621 and the small transmission wheel 2622 to achieve the effect of further speed reduction, and the connection of the conveyor belt 2623 can play the role of protecting the motor 251 when the motor 251 is started or the rotation of the stirring shaft 22 is over-negative.

Alternatively, the conveying belts 2623 are V-belts, and a plurality of conveying belts 2623 are connected between the large driving wheel 2621 and the small driving wheel 2622, so that the transmission torque is large and the belt is not easy to slip.

Of course, the embodiment of the present invention is not limited thereto, and the fecal treatment system 2 may not be provided with the driver 25, for example, when the fecal treatment system 100 is installed near a river, a waterwheel may be provided on the river, and the stirring shaft 22 of the fecal reactor 21 may extend out of the toilet and be connected to the waterwheel, and the rotation of the waterwheel can drive the stirring shaft 22 to rotate.

When driver 25 is provided, driver 25 is also not limited to motor 251, for example, driver 25 may be an engine including a cylinder and piston assembly, which operates to rotate a crankshaft of the piston assembly. The crankshaft can be connected with the stirring shaft 22 through a reduction transmission device, so as to drive the stirring shaft 22 to rotate. The structure and operation of the engine are well known in the art and will not be described herein.

In some embodiments, as shown in fig. 7 and 8, the cross section of the inner cavity of the fecal reactor 21 is circular, which facilitates the rotational mixing of the materials in the fecal reactor 21 when the stirring shaft 22 rotates, and prevents the accumulation of undegraded fecal material in the inner corners of the fecal reactor 21 due to excessive amounts of the material.

Specifically, as shown in fig. 8, the fecal reactor 21 is a cylindrical barrel, the outer diameters of the fecal reactors 21 are equal, the fecal reactors 21 are coaxially arranged, and the stirring shaft 22 and the fecal reactor 21 are also coaxially arranged.

Advantageously, as shown in fig. 8, the stirring shafts 22 in the plurality of fecal reactors 21 are integrally formed, and two adjacent fecal reactors 21 share the same end, or said fecal treatment system 2 is provided with a hollow cylinder 210, the rotatable stirring shaft 22 is provided in the cylinder 210, the cylinder 210 is provided with an insert plate 215, the insert plate 215 partitions the cylinder 210 into the plurality of fecal reactors 21, and the stirring shaft 22 passes through the insert plate 215.

In the example shown in fig. 8, the fecal reactor 21 is provided on an end surface in the shaft hole 211, the system further comprises a felt 233 and an end plate 234, the felt 233 being provided around the shaft hole 211 to improve the tightness of the fecal reactor 21, the end plate 234 being used to fix the felt 233 on the end surface of the fecal reactor 21.

Further, as shown in fig. 5, 6 and 8, supporting seats 231 are provided at both ends of the plurality of fecal reactors 21, and both ends of the stirring shaft 22 are rotatably supported on the two supporting seats 231 after extending out of the plurality of fecal reactors 21. Alternatively, two support bases 231 are fixedly attached to the end face of the fecal reactor 21 at the outermost end among the plurality of fecal reactors 21, as shown in fig. 8, and the support bases 231 are integrally formed with the end portions of the respective fecal reactors 21.

Advantageously, as shown in fig. 8, bearings 232 are provided between the stirring shaft 22 and the respective support seats 231.

Here, a plurality of fecal reactors 21 may be arranged in pairs, the inlets 212 of two fecal reactors 21 of the same pair of fecal reactors 21 being arranged adjacent to each other of the respective fecal reactors 21. Thus, the same pair of excrement reactors 21 can be arranged below the same toilet bowl 4, one toilet bowl 4 corresponds to two excrement reactors 21, the excrement treatment capacity of the toilet bowl 4 is large, the connecting pipeline between the toilet bowl 4 and the excrement reactors 21 is shortest, and the system structure is simplest and reliable. The two fecal reactors 21 can also be used alternately, which can ensure that new fecal is not discharged from the closed fecal reactor 21 during the closing period, and ensure that the material degradation in the closed fecal reactor 21 is more complete.

Advantageously, the mixing shafts 22 of the same pair of faecal reactors 21 are coaxially connected, the mixing shafts 22 of the pair of faecal reactors 21 being driven by the same driver 25, the assembly is easy.

Of course, as shown in fig. 7, two fecal reactors 21 may be provided in one fecal treatment system 2, one fecal reactor 4 for each of the two fecal reactors 21, the inlets 212 of the two fecal reactors 21 being provided adjacent to each other at the top of the respective fecal reactor 21. This arrangement allows for the simplest installation of one faecal management system 2 and one toilet 4 when the system is produced.

Specifically, as shown in fig. 8, each stirring shaft 22 is provided with a stirring blade 221, the stirring blade 221 extends spirally around the stirring shaft 22, the spiral stirring blade 221 is labor-saving in rotation, and the impact resistance is also strong.

Specifically, when the excrement is discharged into the excrement reactor 21, the content of the material in the excrement reactor 21 is changed, and thus the impact force applied to the stirring blades 221 during the stirring process is also changed. Because the stirring blades 221 are spiral, the resistance of the streamline shape is small when the stirring blades 221 rotate, and when the stirring blades 221 enter the manure pile and leave the manure pile in the stirring process, the resistance change on the stirring blades 221 is relatively small, and the load impact is small.

Because the load impact on the stirring blade 221 is small, the impact of the stirring blade 22 on the driver 25 is also small, the vibration of the fecal treatment system 2 is small, and the service life is long.

Advantageously, as shown in fig. 8, the stirring vanes 221 in two adjacent fecal reactors 21 have opposite helical directions, so that the material in fecal reactor 21 can be driven to move away from inlet 212 by controlling the rotation direction of stirring shaft 22, thereby making the distribution of the material more uniform in fecal reactor 21.

Specifically, since the inlets 212 are located adjacent to each other on the paired fecal reactors 21, the fecal matter falling from the inlets 212 is concentrated near the inlets 212, and the space utilization of the rest of the fecal reactor 21 is reduced.

When the stirring vanes 221 rotate, the stirred material receives not only the stirring force in the radial section but also the driving force in the axial direction of the stirring shaft 22. Here, the radial cross section refers to a cross section perpendicular to the central axis of the stirring shaft 22. Taking the example of fig. 8 as an example, under the agitation by the agitating blade 221, the material moves not only in the up-down direction, the front-back direction, but also in the left-right direction.

Because the rotation directions of the stirring blades 221 in the excrement reactors 21 are the same, the spiral directions of two adjacent stirring blades 221 are opposite, and the driving forces of the two adjacent stirring blades 221 to the materials are opposite. Then, the rotation direction of the stirring shaft 22 can be controlled to make the driving direction of the stirring shaft 22 to the materials in the same pair of the fecal reactors 21 opposite.

In this way, the material in each fecal reactor 21 can be pushed towards the rest of the fecal reactor 21 by the inlet 212, so that the material is evenly distributed in the fecal reactor 21, thereby the fecal reactor 21 has high space utilization and strong fecal treatment capacity.

Taking the example of the system in fig. 8 comprising two fecal reactors 21, the two fecal reactors 21 being a left fecal reactor 21a and a right fecal reactor 21b, respectively, the inlets 212 of the two fecal reactors 21 are located adjacent to each other, respectively. The inlet 212 of the left fecal reactor 21a is located at the right end of the top wall of the left fecal reactor 21a and the inlet 212 of the right fecal reactor 21b is located at the left end of the top wall of the right fecal reactor 21 b.

When the excrements are discharged into the left excrement reactor 21a, the excrements are pushed leftward by the stirring vanes 221 of the left excrement reactor 21a, so that the materials can be distributed throughout the left excrement reactor 21 a. When the excrements are discharged into the right excrements reactor 21b, the excrements are pushed to the right by the stirring vanes 221 of the right excrements reactor 21b, so that the materials can be distributed throughout the right excrements reactor 21 b.

Here, the spiral direction of the stirring blade 221 and the rotation direction of the stirring shaft 22 in each fecal reactor 21 can be specifically designed according to the actual situation, and is not particularly limited herein.

In some embodiments, as shown in fig. 7 and 8, each stirring shaft 22 is provided with a large-diameter stirring blade 2211 and a small-diameter stirring blade 2212, and the volume swept by the small-diameter stirring blade 2212 is smaller than the volume swept by the large-diameter stirring blade 2211, so that the material mixing degree can be increased when the stirring shaft 22 rotates.

Specifically, the area of the fecal reactor 21 far from the stirring shaft 22 is agitated and mixed by the action of the large-diameter stirring blade 2211, the area of the fecal reactor 21 near the stirring shaft 22 is agitated and mixed by the action of the small-diameter stirring blade 2212, and the area between the large-diameter stirring blade 2211 and the small-diameter stirring blade 2212 is agitated and mixed by the action of the large-diameter stirring blade 2211 and the small-diameter stirring blade 2212. The arrangement of the large-diameter stirring blade 2211 and the small-diameter stirring blade 2212 enables the flow direction of fluid formed in the inner space of the excrement reactor 21 to be mixed, so that the materials and the microbial inoculum can be better mixed, and the degradation speed is accelerated.

Specifically, as shown in fig. 8, large-diameter stirring blade 2211 and small-diameter stirring blade 2212 each extend spirally around stirring shaft 22, and the spiral directions of large-diameter stirring blade 2211 and small-diameter stirring blade 2212 are opposite. In this way, the driving force directions of the large-diameter stirring blade 2211 and the small-diameter stirring blade 2212 to the material are opposite in the axial direction, and the mixing is more sufficient.

Taking the example of the feces discharged into the left feces reactor 21a in fig. 8, the feces are pushed leftward by the large-diameter stirring blade 2211 of the left feces reactor 21a, so that the material can be distributed in the whole left feces reactor 21a, and at the same time, the material is pushed rightward by the small-diameter stirring blade 2212. Thus, the problem that the materials are totally accumulated on the left side of the left excrement reactor 21a by the large-diameter stirring blades 2211 is avoided, and the distribution of the materials is more uniform. And the materials are stirred back and forth left and right in the left excrement reactor 21a, and the mixing is violent, so that the reaction can be accelerated.

Alternatively, in the paired fecal reactors 21, the large diameter stirring vanes 2211 in the two fecal reactors 21 are opposite in spiral direction, and the small diameter stirring vanes 2212 in the two fecal reactors 21 are also opposite in spiral direction.

Specifically, as shown in fig. 8, a connection column 222 is provided on the stirring shaft 22 of each fecal reactor 21, and a stirring blade 221 is provided on the connection column 222. Optionally, connecting post 222 extends radially outward of agitator shaft 22.

More specifically, the connecting columns 222 are plural, the connecting columns 222 are distributed at intervals along the axial direction of the stirring shaft 22, the stirring blades 221 are plural, and the stirring blades 221 are respectively arranged on the connecting columns 222.

In the example of fig. 8, the stirring shafts 22 include a large-diameter stirring shaft 22 and a small-diameter stirring shaft 22, the large-diameter stirring shafts 22 are disposed on the connecting posts 222 in a one-to-one correspondence, and the small-diameter stirring shafts 22 are also disposed on the connecting posts 222 in a one-to-one correspondence.

Of course, in the embodiment of the present invention, the shape of the stirring vane 221 is not limited to a spiral shape, for example, the stirring vane 221 may be formed as an arc plate, and when there are a plurality of stirring vanes 221, the distribution manner of the plurality of stirring vanes 221 is also not limited.

In one embodiment, as shown in fig. 5 and 6, a material opening 213 is provided below the fecal reactor 21 for communicating the interior, and a material discharge plate 27 for opening or closing the material opening 213 is further provided on the fecal reactor 21, so that when degradation of the fecal in the fecal reactor 21 is completed, the material discharge plate 27 can be opened to take out the degradation product from the material opening 213.

Wherein, establish material mouth 213 in the below of excrement and urine reactor 21, degradation product can roll to material mouth 213 department under the rotation of stirring leaf 221 automatically, need not to take broom, rake to sweep out, and the maintenance of excrement and urine processing system 2 is very convenient, and cleaner of system is lighter when clearing out the degradation product, also more sanitary. At this time, the material tank can be directly placed at the material port 213, and the degradation product can be automatically received.

Alternatively, as shown in fig. 5 and 6, the opposite sides of the spout 213 of the fecal reactor 21 are provided with chutes 214, and the opposite sides of the effusion plate 27 are slidably disposed within the chutes 214. That is to say, the discharging plate 27 is formed as a sliding door, the discharging plate 27 can be arranged on the fecal reactor 21 in a drawing and inserting manner, the opening and closing are convenient, and the discharging plate 27 is not easy to open automatically after being inserted, so that the sealing performance of the fecal reactor 21 during the use period is ensured, and the reliability of the system operation is ensured.

Advantageously, the upper end of chute 214 is open, so that the blanking plate 27 can be removed from above, and the material opening 213 can be closed by the gravity of the blanking plate 27 itself, when the blanking plate 27 is slid down into the chute 214.

Advantageously, the spill plate 27 is provided with a handle 271, and the spill plate 27 can be lifted by a cleaning person to remove the spill plate 27. Alternatively, the handle 271 is formed by bending a portion of the blanking panel 27, which is very easy to manufacture.

In some embodiments, as shown in fig. 7-11, the reversing device 5 includes a reversing plate 51 rotatably disposed in the multi-way tube 6, so that the reversing device 5 has a simple structure, is easy to assemble, has low cost, and is convenient to reverse.

Specifically, as shown in fig. 11, the thickness of the reversing plate 51 gradually decreases in a direction from the rotary shaft end to the free end of the reversing plate 51. The rotating shaft end of the reversing plate 51 refers to the end of the reversing plate 51 where the rotating shaft 510 is arranged, and the free end of the reversing plate 51 refers to the end of the reversing plate 51 away from the rotating shaft 510. As shown in fig. 11, the rotation shaft 510 is provided at the lower end of the reversing plate 51, and the thickness of the reversing plate 51 is gradually reduced in the direction from bottom to top.

The thickness of the reversing plate 51 arranged at the rotating shaft end is larger, so that the structural strength of the reversing plate 51 at the rotating shaft end is enhanced, and the problem that the reversing plate 51 is broken at the rotating shaft end is avoided as much as possible, so that the reversing failure is avoided. The thickness of the commutator plate 51 is gradually reduced from the end of the rotor to the free end, which is beneficial to reducing the mass and further reducing the required torque force.

Advantageously, as shown in fig. 11, the surface of the reversing plate 51 at the free end is an arc surface S1, so that the free end of the reversing plate 51 can abut against the wall of the multi-way tube 6 after reversing, and the wall can form a tangent plane of the arc surface S1, which is tightly adhered, so that excrement is not easy to flow out from the gap between the two, and the reversing reliability is improved.

In some embodiments, as shown in fig. 8, there are two fecal reactors 21 for one toilet 4. The direction changing device 5 alternately connects the feces outlet 4110 of the toilet 4 to the two feces reactors 21.

The multi-way pipe 6 is a three-way pipe 61, the three-way pipe 61 comprises a first pipe 611 and two second pipes 612, the first pipe 611 is connected with the toilet bowl 4, and the two second pipes 612 are respectively connected with the inlets 212 of the two fecal reactors 21.

Specifically, as shown in fig. 10 and 8, the rotating shaft 510 of the reversing plate 51 is disposed adjacent to the pipe connection of the two second pipes 612, and the rotating shaft end of the reversing plate 51 is spaced apart from the pipe connection of the two second pipes 612, so that smooth rotation of the reversing plate 51 can be ensured, and excrement can be prevented from flowing between the reversing plate 51 and the pipe connection of the two second pipes 612 due to the blocking effect of the rotating shaft end of the reversing plate 51.

More specifically, as shown in fig. 8 and 10, the first pipeline 611 includes a vertical section 6111 and an expansion section 6112 connected to the upper end of the vertical section 6111, the cross section of the vertical section 6111 is rectangular, the lower end of the vertical section 6111 is connected to the two second pipelines 612, the reversing plate 51 is disposed in the vertical section 6111, and the cross sectional area of the expansion section 6112 gradually increases from bottom to top.

Thus, the reversing plate 51 is formed into a rectangular plate, the structure is simple, the reversing plate 51 is easy to be attached to the pipe wall, and excrement flowing out from a gap between the reversing plate 51 and the pipe wall is reduced. The expansion section 6112 can be conveniently connected with the toilet stool 4, and the excrement is discharged without leakage.

In some embodiments, as shown in fig. 11 and 4, the reversing device 5 further comprises an operating handle 52, and the operating handle 52 is connected with the rotating shaft 510 of the reversing plate 51, so that the reversing can be manually performed, and the reversing cost is low.

Here, the operation handle 52 can be flexibly provided. For example, in the example of fig. 3, the toilet bowl 4 is a toilet bowl, the toilet bowl is located high, the rotating shaft 510 of the reversing plate 51 can extend out of the toilet bowl from the rear side, and the operating handle 52 is provided at the rear side of the toilet bowl. As shown in FIG. 4, the shaft 510 of the direction changing plate 51 can extend beyond the outer wall 1011 of the housing 101, and the operation handle 52 is disposed at the rear side of the housing 101, so that the direction can be changed from the outside of the excreta management system 100.

In other embodiments, the reversing device 5 further comprises a driving member (not shown) connected to the rotating shaft 510 of the reversing plate 51. For example, the driving member is a driving motor, and the reversing can be realized by controlling the forward and reverse rotation of the driving motor, and preferably, the driving member is a stepping motor.

Specifically, the reversing device 5 further comprises a reversing switch (not shown) electrically connected with the driving member to control the driving member to operate, that is, the reversing device 5 is reversed after the reversing switch is manually triggered.

Of course, the embodiment of the present invention is not limited thereto, for example, the reversing device 5 further includes a controller electrically connected to the driving member to control the driving member to operate periodically. That is, the controller is electrically connected to the driving member to control the driving member to operate every predetermined time, so that the reversing device 5 reverses every predetermined time. This further improves the automation and intelligence of the excrement disposal system 100.

Of course, the predetermined time can be set specifically according to actual conditions, and the predetermined time of each commutation interval can be equal or unequal. For example, when one fecal reactor 21 of the two fecal reactors 21 is large in capacity and the other fecal reactor 21 is small in capacity, the controller may set two predetermined times, wherein the predetermined time is long for the large volume fecal reactor 21 and short for the small volume fecal reactor 21.

Of course, in the embodiment of the present invention, the structure of the reversing device 5 is not limited to the reversing plate 51 rotatably provided in the multi-way pipe 6.

For example, one toilet bowl 4 corresponds to a plurality of fecal reactors 21, and the multi-way tube 6 includes a first tube 611 and a plurality of second tubes 612, the plurality of second tubes 612 being connected to the inlets 212 of the plurality of fecal reactors 21, respectively. The reversing plate 51 is movably provided in the multi-way tube 6, and the reversing plate 51 is provided at a connection of the plurality of second tubes 612 with the first tube 611. The reversing plate 51 is provided with a through opening, when the toilet bowl 4 is required to be connected with one excrement reactor 21, the through opening moves to the second pipeline 612 corresponding to the excrement reactor 21, and the rest second pipelines 612 are closed. When the toilet 4 is required to be connected with another fecal reactor 21, the direction changing plate 51 is moved to the second pipe 612 corresponding to another fecal reactor 21, and the original second pipe 612 is also closed.

For another example, the reversing device 5 may also adopt a structure of a reversing valve disclosed in the prior art, or a structure of a valve body of the reversing valve. For example, the reversing device 5 may be a ball valve spool rotatably disposed within the tee 61. Three communicated pipelines are arranged on the valve core of the ball valve, two pipelines into which the valve core can rotate are respectively communicated with the first pipeline 611 and the second pipeline 612, and the other pipeline is closed.

By arranging the reversing device 5, a plurality of fecal reactors 21 are arranged corresponding to one toilet 4.

In some embodiments, at least a portion of the housing of the photochemical reactor 32 is a light-transmitting member, so that sunlight can directly irradiate the photochemical reactor 32, and algae in the photochemical reactor 32 can be photosynthetic to complete metabolism after receiving the sunlight. The purification is completed by solar energy, and the pollution-free and low energy consumption of the photochemical reactor 32 can be realized.

In other embodiments, light pipes may be disposed within photochemical reactor 32 so that light may be directly used to promote the growth of algae within photochemical reactor 32. Optionally, the tube is an LED lamp.

Of course, the housing of the photochemical reactor 32 may be a light-transmitting member, and a lamp may be disposed in the photochemical reactor 32, so that the algae growth is promoted by the sunlight in sunny days, and the algae growth is promoted by the light in night or rainy days. In this way, the purification of the liquid in photochemical reactor 32 can be effectively accomplished under any circumstances.

In some embodiments, as shown in fig. 9, the urine treatment system 3 further comprises a water pump 33 for pumping the primary treatment liquid in the urine pretreatment tank 31 into the photochemical reactor 32, so that the liquid flow transportation can be completed through an electric control operation, and the automation degree is high.

Specifically, as shown in fig. 9, the urine treatment system 3 further comprises a detector 34 for detecting the liquid level in the urine pretreatment tank 31, and the detector 34 is electrically connected with the water pump 33, so that when the detector 34 detects that the liquid level in the urine pretreatment tank 31 reaches a predetermined liquid level, the primary treatment liquid is pumped out, manual observation is not needed, and the automation degree of the system is improved.

Of course, the control manner of the water pump 33 in the embodiment of the present invention is not limited to this, for example, the water pump 33 may be provided with a control member, and the control member controls the water pump 33 to pump water periodically, that is, the control member controls the water pump 33 to pump water at set time intervals. Of course, the setting time can be specifically set according to actual conditions. The setting time of the interval of each water pumping of the water pump 33 may be equal or different, or the setting time is different in different time periods, and the setting time is equal in the same time period.

For example, in summer, people have more toileting times and large urine volume, in winter, people have less toileting times and small urine volume, water can be pumped every 6 hours from 7 months to 10 months, and water can be pumped every 10 hours from 12 months to 4 months in the coming year.

In some embodiments, the urine treatment system 3 further comprises an ecological wetland (not shown), and the input end of the ecological wetland is connected with the photochemical reactor 32, so that the COD of the urine can be further reduced through the absorption of the ecological wetland.

In one specific example, the ecological wetland may comprise: the wetland tank, filler, vegetation and water distribution piece, the filler is distributed in the wetland tank, the vegetation is planted on the filler, the filler forms the attachment medium for vegetation growth, and the water distribution piece is connected between the photochemical reactor 32 and the wetland tank to add secondary treatment liquid into the wetland tank. The secondary treatment liquid is irrigated on the vegetation, and not only is nutrient substances in the liquid absorbed by leaves, stems and root systems of the vegetation, but also the secondary treatment liquid flows downwards and is filtered by the filler, and when the secondary treatment liquid flows to the bottom of the wetland tank, impurities in the secondary treatment liquid can be filtered out.

The inventor experiments show that after the photochemical reactor 32 acts statistically, the COD of the secondary treatment liquid can be lower than 200mg/L, and after the secondary treatment liquid is absorbed by the ecological wetland, the COD of the secondary treatment liquid can be lower than 50 mg/L.

Alternatively, the packing may comprise sand, dirt, or the like. Optionally, the bottom of the wetland tank can be provided with a leak hole, the leak hole is far away from the water distribution piece in the horizontal direction, the two treated liquids entering the wetland tank are further purified into a three-stage treated liquid after vegetation absorption and sand filtration, and the three-stage treated liquid can flow out from the leak hole.

That is to say, the water distribution piece forms the input end of the ecological wetland, and the leak hole forms the output end of the ecological wetland.

In particular, the ecological wetland is suitable to be provided on the roof of a toilet, i.e. on the roof 1012 of the house body 101. Therefore, the ecological wetland and the toilet are integrated, so that the environment is beautified, the body and the mind are pleased, and the treated product of urine can be treated nearby.

Further, the urine treatment system 3 further comprises a fish tank (not shown) connected to the output end of the ecological wetland or directly connected to the photochemical reactor 32. Thus, if the fish tank is arranged in or near the toilet, the ornamental landscape can be provided, and the joyful body and mind can be achieved.

In the urine treatment system 3, the liquid is in a circulating treatment state all the time after being generated, the fish tank is integrated in the urine treatment system 3, and water in the fish tank circularly flows along with the liquid, so that the energy consumption of the fish tank is reduced. In addition, the third-stage treatment liquid discharged from the ecological wetland or the second-stage treatment liquid discharged from the photochemical reactor 32 provides a nutrient source for aquatic organisms in the fish tank, and the metabolism of the aquatic organisms in the fish tank can further consume nutrient components in the third-stage treatment liquid, so that the dual purposes of waste treatment and feeding are achieved.

The liquid purified by the fish tank is a four-stage treatment liquid which can be directly discharged or can be stored in a water storage tank of a toilet, and when the toilet needs to be flushed, water in the water storage tank can be directly used for flushing.

Of course, the embodiment of the invention is not limited to this, for example, the three-stage treatment liquid after being purified by the ecological wetland can be directly discharged or stored in the water storage tank of the toilet.

Assuming that the family includes four members, one toilet 4 is expected to require two fecal reactors 21 in terms of the amount of feces produced by four persons in a month, i.e., the fecal treatment system 2 is provided with a left fecal reactor 21a and a right fecal reactor 21 b. A toilet bowl 4 is arranged in the excrement treatment system 100, a three-way pipe 61 is arranged below the toilet bowl 4, and an excrement outlet 4110 is connected with the two excrement reactors 21 through the three-way pipe 61. Sawdust and microbial agent are put in the excrement reactor 21 in advance, and excrement enters the excrement reactor 21 to be degraded.

Depending on the type of microbial inoculum selected and the capacity of the fecal reactor 21, it is expected that a single fecal reactor 21 will require fifteen days of oxygen consumption time. Under the reversing action of the reversing device 5, the two fecal reactors 21 are rotated every fifteen days. When the left excrement reactor 21a is in use, the right excrement reactor 21b is sealed and degraded, after fifteen days of degradation, the material port 213 of the right excrement reactor 21b can be opened, and the material is automatically swept out under the rotation of the stirring shaft 22. At this time, a material tank is placed under the material port 213, and the degraded fertilizer automatically falls into the material tank. Then the material port 213 is closed, the direction is changed by the reversing device 5, the left fecal reactor 21a which is originally used is sealed and degraded, and the right fecal reactor 21b which is just emptied is connected with the toilet stool 4.

Urine generated by the toilet stool 4 flows into the urine pretreatment tank 31 through the urine collection pool 412 and the urine collection pot 43, and the adsorbent in the urine pretreatment tank 31 absorbs urea and other components in the urine to eliminate urine odor. When the detector 34 detects that the liquid amount in the urine pretreatment tank 31 reaches a preset value, the water pump 33 is driven to operate, the water pump 33 pumps the primary treatment liquid into the photochemical reactor 32, and the liquid is converted into the secondary treatment liquid through the absorption of algae in the reactor. And then, conveying the secondary treatment liquid into an ecological wetland on the roof of the toilet, performing three-stage purification on the ecological wetland, conveying the generated three-stage treatment liquid into the fish tank, and performing secondary purification on the three-stage treatment liquid through biological metabolism in the fish tank. The purified four-stage treatment liquid can be conveyed into a water storage tank of a toilet for flushing the toilet and the like.
