Description

Technical Field

[0001] The present invention relates to the technical field of ecological public toilets, specifically a microbial treatment system for a sewerless ecological public toilet. Background Art

[0002] Currently, the most widely used ecological public toilets are those that use microbial strains to decompose feces. They utilize their growth and reproduction activities to biodegrade the available macromolecular organic compounds in feces and convert them into microbial biomass, competitively inhibiting and killing pathogenic microorganisms in feces, adsorbing, degrading, and converting the odor substances generated in feces, achieving the harmless and resourceful treatment of feces. They can achieve the function of zero emissions and cause no pollution to the environment at all.

[0003] For example, an ecological toilet proposed in the prior art degrades the organic matter in feces and urine, including: a toilet main body; an energy collection part that collects solar energy and the chemical energy contained in organic matter; a liquid recovery part that collects rainwater and urine; and a degradation part that degrades organic matter. Among them, the energy collection part has a solar energy conversion unit, a microbial battery, and an electric energy storage unit respectively connected to the solar energy conversion unit and the microbial battery, which are provided on the toilet main body. The waste liquid recovery part has a rainwater collection unit connected to the toilet main body, and a recovery and regeneration unit that recovers urine and processes it to obtain reclaimed water. The degradation part has a baffle anaerobic pond that receives feces and urine and performs anaerobic degradation, and a microbial electrolysis unit with electrodes located in the baffle anaerobic pond for electrochemically degrading feces and urine. On the one hand, the present invention can utilize the green energy in nature as the energy source for the electrical appliances in the toilet.

[0004] Another example is a zero-emission ecological toilet proposed in the prior art, which is simple in structure, pollution-free, and water-free. It includes a frame, a housing, and a toilet bowl. A trough with a built-in microbial bed is installed on the frame and communicates with the outlet of the toilet bowl. The trough is equipped with a stirrer composed of a stirring shaft and stirring claws. The stirring shaft driven by power is provided with more than three groups of T-shaped stirring claws distributed staggeredly along the radial direction of the stirring shaft. The angle between the stirring rod at the front end of the T-shaped stirring claw and the axis of the stirring shaft is within the range of 5° to 50°. The stirring claws stir the feces and microbial strains for full fermentation and decomposition. A heating device for volatilizing liquid is also installed at the bottom of the trough. The fecal contaminants are biochemically treated by microorganisms, so that the fecal contaminants and microorganisms form a mutually dependent ecological chain. They are decomposed into water and odorless gas, and a small amount of fully fermented and mature organic fertilizer remains, which serves as the nutrient for the microorganisms to maintain their survival, and the water is volatilized through the heating device.

[0005] However, in the prior art, including the above-disclosed technologies, when in use, feces fall into the collection tank through the defecator. First, it is easy for feces to adhere to the defecator and is not easy to clean. Second, fresh feces have not been decomposed by microorganisms, so the odor inevitably escapes from the holes of the defecator. There are also technologies that propose to set up a deodorization device above the defecator, but the odor will still pass through the user and be smelled during the process of being absorbed and treated by the deodorization device. Especially after the previous user has finished using, the cover plate closes the defecator, and there is still an odor inside the defecator when the feces inside the defecator are transported backward. When the next user uses it, the odor accumulated in the defecator gushes out, resulting in a very poor experience for the user. Therefore, it is necessary to improve and optimize the structure of the microbial treatment system for the sewerless ecological public toilet. Summary of the Invention

[0019] (III) Beneficial effects

[0020] The present invention provides a microbial treatment system for a sewerless ecological public toilet, which has the following beneficial effects:

[0021] 1. Compared with the prior art, in this sewerless ecological public toilet microbial treatment system, the fecal collector and the feeding pipe are connected through a connecting pipe. The connecting pipe is arranged in a shape that is smaller at the top and larger at the bottom. Feces directly fall into the feeding pipe and will not adhere to the side wall of the fecal collector or the connecting pipe, reducing the cleaning and maintenance work. After defecation, the motor drives the rotating shaft and the auger blades to rotate, pushing the feces towards the solid-liquid separator.

[0022] 2. Compared with the prior art, in this sewerless ecological public toilet microbial treatment system, after the upper cover plate of the fecal collector is opened and for a period of time after it is closed, the air in the fecal chamber is continuously extracted by the fan, deodorized and filtered through the deodorizing box, and then discharged into the high altitude through the exhaust pipe, which can prevent the odor from entering the interior of the public toilet body along the fecal collector and affecting the users. At the same time, fresh air is inhaled along the second air pipe to keep the internal air fresh.

[0023] 3. Compared with the prior art, in this sewerless ecological public toilet microbial treatment system, the urine after solid-liquid separation flows into the water storage tank after being treated in the urine treatment tank to form flushing water. The booster pump pumps and pressurizes the water from the water storage tank, and then flushes the inner side wall of the feeding pipe and the auger blades through the water pipe and the third joint. The flushing water enters the solid-liquid separator again for separation for recycling. After the feeding pipe and the auger blades are flushed, the odor residue is reduced.

The urine in the urine treatment tank is treated to form flushing water, which overflows into the water storage tank and can be used to flush the feeding pipe 10. During installation, the equipment box 2 is located underground and the top of the equipment box 2 is flush with the ground;

[0035] As Figure 1 shown in the figure, in order to facilitate the use of electricity inside the public toilet body 1, a charging structure for charging the battery pack is provided on the top of the public toilet body 1. The charging structure includes multiple groups of photovoltaic panels 4. The multiple groups of photovoltaic panels 4 are fixedly connected to the upper wall of the public toilet body 1 in a rectangular array in sequence. The multiple groups of photovoltaic panels 4 are electrically connected to the battery pack through a charging protection circuit. By setting the multiple groups of photovoltaic panels 4, the battery pack can be charged, saving the expenditure on mains electricity to a certain extent;

[0036] As Figure 2 、 Figure 7 shown in the figure, in order to be able to close the toilet bowl 6 after use, a toilet bowl 6 is provided on the inner lower wall of the public toilet body 1. On the inner lower wall of the public toilet body 1 and on both the front and rear sides of the toilet bowl 6, a group of pedals 8 are slidably connected through connecting seats 22. The toilet bowl 6 penetrates through the lower wall of the public toilet body 1 and extends below the public toilet body 1.

The extending ends of the two groups of cylinders 30 are respectively fixedly connected to the left and right sides of the toilet bowl 6. The cylinders 30 are controlled to act through a switch structure. When the extending shafts of the two groups of cylinders 30 extend, they can drive the two groups of covers 7 to move away from each other to open the defecation cavity. After defecation, the extending shafts of the two groups of cylinders 30 retract, which can drive the two groups of covers 7 to move closer to each other, so as to play a role in closing the defecation cavity after the two groups of covers 7 are closed;

[0037] As Figure 5As shown in the figure, in order to ensure that the cover plate 7 can only be opened when someone is using it, a switch structure for controlling the operation of the closing drive structure is provided between the pedal 8 and the connecting seat 22. The switch structure includes a sliding seat 23, a sliding rod 24, a first spring 25, a trigger switch 26, a trigger head 28, and a second spring 29.

One end of the sliding rod 24 away from the pedal 8 is slidably connected to the inner wall of the sliding seat 23. The first spring 25 is sleeved on the outer wall of the sliding rod 24 and is located between the upper end of the sliding seat 23 and the inner upper wall of the pedal 8. The trigger head 28 is slidably connected to the inner upper wall of the pedal 8 through a limit sleeve 27 and is vertically opposite to the trigger switch 26. The second spring 29 is arranged on the inner wall of the limit sleeve 27 and is located between the trigger head 28 and the inner upper wall of the pedal 8. When someone is using it, both feet step on a group of pedals 8 respectively. The pedals 8 are stepped on and move downward, driving the trigger head 28 to abut against the trigger switch 26, thereby triggering the control of the cylinder 30. After use, the user leaves the pedal 8, and the pedal 8 is driven by the elasticity of the first spring 25 to move upward and reset. The trigger head 28 leaves the trigger switch 26, and the cylinder 30 resets;

[0038] As Figure 7 shown in the figure, in order to improve the closing effect, a sealing structure for maintaining the seal is provided between the opposite ends of the two groups of cover plates 7 and between the cover plate 7 and the opposite side of the toilet 6. The sealing structure includes a docking groove 32, a docking head 33, and two groups of telescopic rubber sleeves 34. The two groups of telescopic rubber sleeves 34 are respectively fixedly connected to the outer walls of the ends of the two groups of cover plates 7 extending outside the toilet 6. The opposite ends of the two groups of telescopic rubber sleeves 34 are respectively fixedly connected to the left and right sides of the toilet 6. The docking groove 32 and the docking head 33 are respectively arranged on the opposite sides of the two groups of cover plates 7. The outer wall of the docking head 33 is adapted to the inner wall of the docking groove 32 in size. When the two groups of cylinders 30 drive the two groups of cover plates 7 to close, the docking head 33 is inserted into the inner wall of the docking groove 32, improving the sealing effect between the two groups of cover plates 7;

[0039] As Figure 3 shown in the figure, in order to prevent feces from sticking, a connecting pipe 9 is fixedly connected to the lower end of the toilet 6, and a feeding pipe 10 is fixedly connected to the lower end of the connecting pipe 9. A feces discharge cavity for communicating the toilet 6 and the feeding pipe 10 is arranged inside the connecting pipe 9. The feces discharge cavity is in a shape with a smaller upper part and a larger lower part. The feces discharge cavity is arranged with a smaller upper part and a larger lower part, which can effectively prevent feces from sticking to the side wall of the feces discharge cavity;

[0040] As Figure 3 、 Figure 4As shown in the figure, in order to convey feces to the subsequent process, one end of the feeding pipe 10 far away from the connecting pipe 9 penetrates through the side wall of the equipment box 2 and extends into the equipment box 2. One end of the feeding pipe 10 extending into the equipment box 2 is connected to the solid-liquid separation device. A screw blade 12 is rotatably connected inside the feeding pipe 10 through a rotating shaft 11. The screw blade 12 is composed of a metal skeleton 1201 and a rubber coating layer 1202. The metal skeleton 1201 is fixedly connected to the outer wall of the rotating shaft 11 in a spiral shape. The rubber coating layer 1202 is coated on the outer wall of the metal skeleton 1201. One side of the rubber coating layer 1202 far away from the center of the rotating shaft 11 is slidably connected to the inner side wall of the feeding pipe 10. A rotating drive structure for driving the rotating shaft 11 is provided at one end of the feeding pipe 10 far away from the equipment box 2. The rotating drive structure is a motor 13. The motor 13 is fixedly connected to one end of the feeding pipe 10 far away from the equipment box 2 through a fixing seat. One end of the rotating shaft 11 far away from the equipment box 2 sequentially penetrates through one end of the feeding pipe 10 far away from the equipment box 2 and the right wall of the fixing seat and extends into the fixing seat. One end of the rotating shaft 11 extending into the fixing seat is fixedly connected to the end of the protruding shaft of the motor 13 through a coupling. After the motor 13 is started, the screw blade 12 can be driven to rotate through the rotating shaft 11, and then the feces can be pushed towards the solid-liquid separation device through the screw blade 12. The screw blade 12 is slidably connected to the inner side wall of the feeding pipe 10 through the rubber coating layer 1202, so that less residue remains on the inner side wall of the feeding pipe 10;

[0041] As Figure 2 shown, in order to maintain the air quality inside the defecation chamber, a fresh air ventilation structure for keeping the air inside the connecting pipe 9 fresh by means of a fan is provided between the public toilet body 1 and the connecting pipe 9. The fresh air ventilation structure includes a first joint 14, a second joint 16, a first air pipe 15, a second air pipe 17 and an exhaust pipe 5. The first joint 14 and the second joint 16 are respectively fixedly connected to the left and right side walls of the connecting pipe 9. The first joint 14 is close to the lower end of the connecting pipe 9, and the second joint 16 is close to the upper end of the connecting pipe 9. The exhaust pipe 5 is fixedly connected to the rear wall of the public toilet body 1. The upper end of the exhaust pipe 5 extends above the public toilet body 1. The first air pipe 15 and the second air pipe 17 are respectively fixedly connected to one end of the first joint 14 far away from the connecting pipe 9 and one end of the second joint 16 far away from the connecting pipe 9. One end of the first air pipe 15 far away from the first joint 14 is fixedly connected to the inlet end of the fan through a deodorizing box. The lower end of the exhaust pipe 5 is fixedly connected to the outlet end of the fan. The second air pipe 17 extends to the rear side of the public toilet body 1. The fan sucks air from the defecation chamber along the first air pipe 15, and after being deodorized by the deodorizing box, it is sent into the high altitude through the exhaust pipe 5. During the process of the fan sucking air from the defecation chamber, air is simultaneously sucked from the upper end, the lower end of the defecation chamber and the second air pipe 16, forming an air flow entering the defecation chamber from the inside of the public toilet body 1, which can prevent the odor inside the defecation chamber from spreading into the public toilet body 1;

[0042] As Figure 2As shown in the figure, in order to flush the inside of the feeding pipe 10, a flushing structure for pumping water from the water storage tank to flush the inside of the feeding pipe 10 is provided between the feeding pipe 10 and the water storage tank. The flushing structure includes a booster pump 21, a solenoid valve 19, and a third joint 18. The third joint 18 is fixedly connected to the upper wall of the feeding pipe 10 and is located near the end of the feeding pipe 10 away from the equipment box 2. The booster pump 21 is fixedly connected to the lower wall of the public toilet body 1. The booster pump 21 and the third joint 18 are connected through a water pipe 20. The solenoid valve 19 is fixedly connected to the outer wall of the water pipe 20. One end of the booster pump 21 away from the solenoid valve 19 is communicated with the water storage tank through a pipeline. The flushing water formed after being treated by the urine treatment tank enters the water storage tank, is pressurized after being pumped by the booster pump 21, and flushes the inside of the feeding pipe 10 and the auger blade 12 along the water pipe 20 and the third joint 18. The wastewater generated after flushing enters the solid-liquid separation device again for separation.

[0043] Working principle: After defecation, it is sent into the solid-liquid separator through the feeding pipe 10 for solid-liquid separation. After separation, the solid enters the microbial fermentation tank, and the liquid enters the urine treatment tank. The urine in the urine treatment tank is treated to form flushing water, which overflows into the water storage tank and can be used to flush the feeding pipe 10. Multiple groups of photovoltaic panels 4 are electrically connected to the battery pack through a charging protection circuit. By setting multiple groups of photovoltaic panels 4, the battery pack can be charged, saving the expenditure on commercial power to a certain extent. The cylinder 30 controls its action through a switch structure. When the extending shafts of the two cylinders 30 extend, they can drive the two cover plates 7 to move away from each other to open the defecation cavity. After defecation, the extending shafts of the two cylinders 30 retract, driving the two cover plates 7 to move closer to each other, so as to close the defecation cavity after the two cover plates 7 are closed. When the two cylinders 30 drive the two cover plates 7 to close, the docking head 33 is inserted into the inner side wall of the docking groove 32, improving the sealing effect between the two cover plates 7. When someone uses it, each foot steps on a pedal 8. When the pedal 8 is stepped on and moves downward, it drives the trigger head 28 to press against the trigger switch 26, thereby triggering the control of the cylinder 30. After use, the user leaves the pedal 8, and the pedal 8 moves upward and resets under the elastic force of the first spring 25. The trigger head 28 leaves the trigger switch 26, and the cylinder 30 resets. A defecation cavity for connecting the defecator 6 and the feeding pipe 10 is arranged inside the connecting pipe 9. The defecation cavity is arranged with a smaller upper part and a larger lower part, which can effectively prevent feces from adhering to the side wall of the defecation cavity. After the motor 13 is started, it can drive the auger blade 12 to rotate through the rotating shaft 11, and then push the feces towards the solid-liquid separation device through the auger blade 12. The auger blade 12 is slidably connected to the inner side wall of the feeding pipe 10 through a rubber coating layer 1202, so that less residue remains on the inner side wall of the feeding pipe 10. The fan sucks air from the defecation cavity along the first air pipe 15, and after being deodorized by the deodorization box, it is sent into the high altitude through the exhaust pipe 5. During the process of the fan sucking air from the defecation cavity, it simultaneously sucks air from the upper end, lower end and the second air pipe 16 of the defecation cavity, forming an air flow entering the defecation cavity from inside the public toilet body 1, which can prevent the odor inside the defecation cavity from spreading into the public toilet body 1. The flushing water formed after being treated in the urine treatment tank enters the water storage tank, is pressurized after being pumped by the booster pump 21, and flushes the inside of the feeding pipe 10 and the auger blade 12 along the water pipe 20 and the third joint 18. The wastewater generated after flushing enters the solid-liquid separation device for separation again.

[0044] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
