Description

Technical Field

[0001] This invention relates to the field of prefabricated rural ecological public health technology, specifically to a prefabricated rural ecological public health device and its working method. Background Technology

[0002] Ecological toilets are a type of environmentally friendly toilet. They refer to toilets that do not pollute the environment, make full use of various resources, and emphasize the self-purification of pollutants and the recycling of resources. Currently, the most widely used ecological toilets are those that decompose feces using microbial strains, thereby achieving the harmless and resource-based treatment of feces.

[0003] Referring to Chinese patent (patent number: CN202211130404.3, patent name: a self-circulating water flushing mobile biological toilet), it includes an installation base plate and a fecal device, wherein the fecal device is fixedly connected to the upper surface of the installation base plate, and the bottom of the installation base plate is provided with a fecal crushing mechanism, a sewage pressure filtration mechanism and a fecal treatment mechanism.

[0004] Because the treatment tank is in a sealed state, feces and sewage are stored in the treatment tank for a long time. As a result, the organic matter in the feces and sewage undergoes anaerobic digestion to produce biogas. The above-mentioned device is difficult to collect the biogas in the treatment tank, which leads to excessive gas pressure inside the treatment tank and is prone to explosion, resulting in poor performance.

[0005] To this end, we propose a prefabricated rural ecological public health device and its working method. Summary of the Invention

[0006] The purpose of this invention is to provide a prefabricated rural ecological public health device and its working method, which has the advantage of collecting biogas inside the treatment box and solves the problems in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a prefabricated rural ecological public health device and its working method, comprising a treatment box, a base movably connected to the inner wall of the treatment box, a connecting pipe for discharging feces and sewage into the treatment box through and fixedly connected to the top of the treatment box, a collection box for collecting biogas fixedly connected to one side of the top of the treatment box, a cylindrical shell movably connected to the side of the treatment box near the collection box, an air inlet pipe movably connected to the outer contour of the cylindrical shell near the top side through to the inner wall and fixedly connected, an end of the air inlet pipe away from the cylindrical shell movably connected to the inner wall of the collection box and fixedly connected, a piston plate movably connected to the inner wall of the cylindrical shell for reciprocating movement according to changes in the internal air pressure of the treatment box, and a screw fixedly connected to the bottom of the piston plate, a stirring mechanism for stirring the feces at the bottom of the base, and a separation mechanism for separating the feces and sewage inside the treatment box.

[0008] Preferably, the stirring mechanism includes a sleeve rod that passes through and is rotatably connected to the base, and a spiral blade for stirring the feces is fixedly connected to the outer contour of the sleeve rod. A rotating rod passes through and is movably connected to the inner wall of the sleeve rod, and the end of the rotating rod away from the cylindrical shell passes through the processing box and is rotatably connected. The end of the screw away from the piston plate passes through the inner wall of the rotating rod and is movably connected. A threaded sleeve is fixedly connected to the top of the rotating rod, and the threaded sleeve is screwed to the screw. A fixing block is fixedly connected to the bottom of the base, and a moving mechanism for pushing the base to move up and down and reciprocate is provided on the fixing block.

[0009] Preferably, the moving mechanism includes a groove on one side of a fixed block, and a rotating rod passing through the inner wall of the groove and rotatably connected thereto. A worm gear for axial reciprocating movement is movably connected to the rotating rod on the inner wall of the groove. A worm wheel is rotatably connected to the end of the inner wall of the groove away from the worm gear via a pin. A connecting rod is coaxially fixed to the worm wheel. A support rod is rotatably connected to the end of the connecting rod away from the worm wheel via a pin. A connecting seat is fixedly connected to the bottom of the processing box near the support rod, and the end of the support rod away from the connecting rod is rotatably connected to the connecting seat via a pin.

[0010] Preferably, the treatment box is provided with a filtration mechanism to prevent the mixing of feces and sewage at the bottom. The filtration mechanism includes rectangular frames fixedly connected to corresponding positions on the four sides of the inner wall of the treatment box. The inner walls of the four rectangular frames are movably connected to first sliders. The bottom of each first slider is rotatably connected to an adjusting rod via a pin. A filter screen for filtering feces is provided between every two adjusting rods. A rectangular sleeve that pushes the adjusting rod to expand and contract is movably connected to the outer contour of the rotating rod near the sleeve rod end. The ends of the four adjusting rods away from the first sliders are rotatably connected to the rectangular sleeves at corresponding positions via pins.

[0011] Preferably, a liquid storage tank is fixedly connected to one side of the treatment tank. The top of the liquid storage tank extends through to the inner wall and is fixedly connected to an inlet pipe for collecting wastewater from inside the treatment tank into the liquid storage tank. The end of the inlet pipe away from the liquid storage tank extends through to the inner wall of the treatment tank, and a drain pipe is fixedly connected to one side of the liquid storage tank for discharging wastewater from inside the liquid storage tank.

[0012] Preferably, the separation mechanism includes a U-shaped frame fixedly connected to the inner wall of the processing tank at a position corresponding to the inlet pipe, and a sealing plate movably connected to the inner wall of the U-shaped frame to seal the inlet pipe. A connecting block is provided on the sealing plate, and a second slider is movably connected to the inner wall of a rectangular frame near the connecting block. The top of the second slider is rotatably connected to a push rod that pushes the sealing plate to seal and release the seal on the inlet pipe via a pin, and the end of the push rod away from the second slider is rotatably connected to the push rod via a pin. A spring is fixedly connected to the second slider on the opposite surface of the rectangular frame on the side away from the first slider to support the second slider.

[0013] Preferably, the collection box is equipped with a biogas internal combustion engine for burning biogas to generate electricity. A concentration detector for detecting biogas concentration is fixedly connected to the inner wall of the collection box, and the concentration detector is connected to the biogas internal combustion engine. The processing box is equipped with a battery for storing the electrical energy generated by the biogas internal combustion engine, and the battery is electrically connected to the biogas internal combustion engine.

[0014] Preferably, a method for operating a prefabricated rural ecological public health device includes the following steps:

[0015] S1. Collect biogas: Collect biogas inside the treatment box into the collection box through the air inlet pipe;

[0016] S2. Stirring operation: The feces on the base are stirred by the spiral blades;

[0017] S3, Lifting Operation: As the worm gear drives the connecting rod to rotate, the fixed block, supported by the support rod, pushes the base to move upward in the vertical direction closer to the cylindrical shell.

[0018] S4. Filtration operation: The first slider is pushed outward by the adjustment rod under the action of the rectangular sleeve, and the adjustment rod is equipped with a filter screen to filter the feces.

[0019] S5. Separation Operation: The clearer sewage at the top of the rectangular frame can be drawn into the storage tank through the inlet pipe, further realizing the separation of sewage and feces.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] 1. As the manure inside the treatment tank ferments with microorganisms in the sewage for an extended period, a large amount of biogas is produced, causing the internal pressure of the treatment tank to continuously increase. Under this pressure, the piston plate drives the screw to move towards the intake pipe. When the piston plate reaches the top of the intake pipe, the intake pipe connects to the cylindrical shell and the treatment tank. The biogas inside the treatment tank is then collected into the collection tank through the intake pipe. The input end of the biogas internal combustion engine is connected to the collection tank, sending the biogas stored in the collection tank to the generator set through the input end. The biogas then enters the internal combustion engine and undergoes regulation, metering, and... Preheating: When the biogas concentration inside the collection box reaches a certain level, the concentration detector can start the biogas internal combustion engine. The internal combustion engine mixes the biogas with air and burns it to generate power, which drives the generator to produce electricity. The electricity is stored in the battery installed on the treatment box and electrically connected to the biogas internal combustion engine. The battery is also connected to the lighting appliances in the ecological toilet, thus powering the lighting appliances in the ecological toilet, further improving the comprehensive utilization efficiency of biogas and increasing its economic value.

[0022] Second, as the piston plate drives the screw to move closer to the air intake pipe, the threaded sleeve on the rotating rod, which is screwed to the screw, enables the rotating rod to rotate on a fixed axis. Through the sleeve rod and helical blades on the base, with the sleeve rod axially connected to the rotating rod, the sleeve rod can rotate synchronously with the rotating rod, causing the helical blades to stir the manure on the base. This accelerates the reaction between the manure and microorganisms, thus speeding up biogas production and further pushing the piston plate and screw closer to the air intake pipe.

[0023] The worm gear mounted on the rotating rod rotates synchronously with the rotating rod on a fixed axis. A worm wheel mounted on the fixed block meshes with the worm gear, causing the worm gear to rotate on the fixed block on a fixed axis. A connecting rod mounted on the worm wheel and a connecting seat mounted on the treatment box allow the support rod to rotate rotatably with the connecting rod and the connecting seat. As the worm wheel drives the connecting rod to rotate, the fixed block, supported by the support rod, pushes the base upwards towards the vertical direction close to the cylindrical shell. The sleeve rod moves synchronously with the base to facilitate the subsequent separation and discharge of feces and sewage.

[0024] Fourth, as the adjusting rod pushes the first slider to move outward, the second slider on the rectangular frame, and the spring on the second slider, cause the first slider to move and contact the second slider, pushing it towards the connecting block. The spring is then compressed. Through the connecting block on the sealing plate, and the push rod rotatably connected to the connecting block and the second slider, the push rod, under the action of the second slider, pushes the sealing plate to move vertically away from the rectangular frame. When the sealing plate disengages from the inlet pipe, the sealing plate releases the seal on the inlet pipe, allowing the inlet pipe to draw sewage from the top of the rectangular frame into the storage tank, further separating sewage and feces. At the same time, the drain pipe transports the water inside the storage tank to the biological filter, where microorganisms attached to the packing material biodegrade organic matter, nitrogen, and phosphorus in the sewage. Simultaneously, the physical filtration of the packing material removes suspended solids, improving the quality of the effluent.

[0025] The combined use of the above structures solves the problem that the device has difficulty collecting biogas in the treatment box, which leads to excessive gas pressure inside the treatment box and is prone to explosion. Attached Figure Description

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Example 1:

[0038] Please see Figures 1 to 9 This invention provides a technical solution: a prefabricated rural ecological public health device and its working method, including a treatment box 1, a base 2 movably connected to the inner wall of the treatment box 1, a connecting pipe 3 that discharges feces and sewage into the treatment box 1 through and fixedly connected to the top of the treatment box 1, a collection box 5 for collecting biogas fixedly connected to one side of the top of the treatment box 1, a cylindrical shell 4 that is movably connected to the side of the treatment box 1 near the collection box 5, an air inlet pipe 6 that is movably connected to the outer contour of the cylindrical shell 4 near the top to the inner wall, the end of the air inlet pipe 6 away from the cylindrical shell 4 that is movably connected to the inner wall of the collection box 5, a piston plate 7 that moves up and down according to the change of air pressure inside the treatment box 1, and a screw 8 fixedly connected to the bottom of the piston plate 7, a stirring mechanism for stirring the feces at the bottom on the base 2, and a separation mechanism for separating the feces and sewage inside the treatment box 1 on the treatment box 1.

[0039] The aforementioned structure is installed at the bottom of the external prefabricated wooden ecological toilet. The connection methods for the prefabricated wooden ecological toilet include: At the connection between the single-sloping beam and the column: a tenon is cut at the upper end of the wooden column, one end of the single-sloping beam is inserted into the tenon, and fixed with bolts to form a rigid connection; at the connection between the double-sloping beam and the column: two adjacent tenons are cut at the upper end of the wooden column, both ends of the double-sloping beam are inserted into the tenons, and fixed with bolts to form a rigid connection; at the connection between the wooden frame column and the foundation pile: a tenon is cut at the lower end of the wooden column, and the wooden frame column is then connected to the foundation pile. The columns are inserted into the tenons of the pre-driven wooden foundation piles and secured with bolts to form a rigid connection. At the apex of the wooden roof, the six diagonal beams are bolted together at one end to form a hexagonal structure. At the edge of the wooden roof, the main and secondary diagonal beams are screwed or bolted together at one end to form a triangular structure. The roof of the eco-toilet is a wooden structure, consisting of wooden roof panels, fixing strips, waterproof membrane, planks, rafters, and aluminum-magnesium-manganese alloy. The roof structure consists of roof panels, with the wooden roof panels made of multi-layer plywood or particleboard, fixed roof strips made of timber strips or timber tubing, waterproof membrane made of asphalt or polymer membrane, wood planks made of multi-layer plywood, rafters made of timber strips, and aluminum-magnesium-manganese metal roof panels made of colored aluminum-magnesium-manganese metal sheets. The wooden roof panels are connected to the toilet frame beams, the fixed roof strips are connected to the wooden roof panels, the waterproof membrane is laid on the fixed roof strips, the wood planks are laid on the waterproof membrane, the rafters are connected to the wood planks, and the aluminum-magnesium-manganese metal roof panels are connected to the rafters. The roof structure consists of wooden roof panels, fixed roof strips, wood planks, and... The rafters are connected by screws, and the aluminum-magnesium-manganese metal roof panels are connected by self-tapping screws. The above-mentioned prefabricated ecological toilet uses a prefabricated wooden frame and aluminum alloy decorative panels, which can be quickly installed and disassembled, saving material and labor costs. At the same time, it has good heat insulation, sound insulation, fire resistance and corrosion resistance. The toilet also uses a rainwater harvesting system to collect rainwater from the roof and walls into an underground storage tank. After simple treatment, it is used for flushing, irrigation and landscaping, realizing the recycling of rainwater and reducing dependence on and pollution of groundwater resources.

[0040] In use, the base 2 and connecting pipe 3 on the treatment box 1 are connected to the output end of the ecological toilet, allowing feces and sewage to fall onto the base 2 inside the treatment box 1 through the connecting pipe 3. The cylindrical shell 4 on the treatment box 1 is connected to the treatment box 1. The collection box 5 and air inlet pipe 6 on the treatment box 1 connect the cylindrical shell 4 and the collection box 5. The piston plate 7 and screw 8 on the cylindrical shell 4 cause the feces inside the treatment box 1 to ferment with microorganisms in the sewage for a long time, producing a large amount of biogas. This causes the air pressure inside the treatment box 1 to increase continuously. Under the air pressure inside the treatment box 1, the piston plate 7 drives the screw 8 to move towards the air inlet pipe 6. When the piston plate 7 moves to the top of the air inlet pipe 6, the air inlet pipe 6 is connected to the cylindrical shell 4 and the treatment box 1, and the biogas inside the treatment box 1 is collected into the collection box 5 through the air inlet pipe 6.

[0041] Example 2:

[0042] Building upon Example 1, the following is a further step:

[0043] The mixing mechanism includes a sleeve rod 12 that passes through and is rotatably connected to the base 2, and a spiral blade 121 for mixing feces is fixedly connected to the outer contour of the sleeve rod 12. A rotating rod 13 passes through and is movably connected to the inner wall of the sleeve rod 12, and the end of the rotating rod 13 away from the cylindrical shell 4 passes through the processing box 1 and is rotatably connected. The end of the screw 8 away from the piston plate 7 passes through the inner wall of the rotating rod 13 and is movably connected. A threaded sleeve 14 is fixedly connected to the top of the rotating rod 13 and is screwed to the screw 8. A fixing block 15 is fixedly connected to the bottom of the base 2, and a moving mechanism for pushing the base 2 to move up and down and back and forth is provided on the fixing block 15.

[0044] During use, as the piston plate 7 drives the screw 8 to move closer to the air intake pipe 6, the threaded sleeve 14 on the rotating rod 13, which is screwed to the screw 8, allows the threaded sleeve 14 to drive the rotating rod 13 to rotate on a fixed axis. Through the sleeve rod 12 and the spiral blade 121 on the base 2, with the sleeve rod 12 axially connected to the rotating rod 13, the sleeve rod 12 can rotate synchronously with the rotating rod 13 to drive the spiral blade 121 to rotate on a fixed axis. This allows the spiral blade 121 to stir the manure on the base 2, accelerating the reaction speed between the manure and microorganisms, thereby accelerating the generation of biogas, and further pushing the piston plate 7 and the screw 8 closer to the air intake pipe 6.

[0045] Example 3:

[0046] Building upon Example 2, the following is a further step:

[0047] The moving mechanism includes a groove 151 on one side of a fixed block 15, and a rotating rod 13 passes through the inner wall of the groove 151 and is rotatably connected. A worm gear 16 for axial reciprocating movement is movably connected to the rotating rod 13 on the inner wall of the groove 151. A worm wheel 17 is rotatably connected to the end of the inner wall of the groove 151 away from the worm gear 16 via a pin. A connecting rod 18 is coaxially fixed to the worm wheel 17. A support rod 19 is rotatably connected to the end of the connecting rod 18 away from the worm wheel 17 via a pin. A connecting seat 20 is fixedly connected to the bottom of the processing box 1 on the side near the support rod 19, and the end of the support rod 19 away from the connecting rod 18 is rotatably connected to the connecting seat 20 via a pin.

[0048] In use, the worm gear 16 on the rotating rod 13 rotates synchronously with the rotating rod 13. The worm wheel 17 on the fixed block 15 meshes with the worm gear 16, so the worm gear 16 drives the worm wheel 17 to rotate synchronously on the fixed block 15. The connecting rod 18 on the worm wheel 17 and the connecting seat 20 on the treatment box 1 allow the support rod 19 to rotate rotatably with the connecting rod 18 and the connecting seat 20. As the worm wheel 17 drives the connecting rod 18 to rotate, the fixed block 15, supported by the support rod 19, pushes the base 2 to rise and move vertically towards the cylindrical shell 4. The sleeve rod 12 moves synchronously with the base 2 to facilitate the subsequent separation and discharge of feces and sewage.

[0049] When the base 2 moves in a vertical direction closer to the cylindrical housing 4, the internal air pressure of the processing box 1 near the cylindrical housing 4 becomes positive, so that the base 2 can further push the piston plate 7 and the screw 8 to move closer to the air intake pipe 6.

[0050] Example 4:

[0051] Building upon Example 3, the following is a further step:

[0052] The treatment box 1 is equipped with a filtration mechanism to prevent the mixing of feces and sewage at the bottom. The filtration mechanism includes rectangular frames 21 fixedly connected to corresponding positions on the four sides of the inner wall of the treatment box 1. The inner walls of the four rectangular frames 21 are movably connected to the first sliders 22. The bottom of each first slider 22 is rotatably connected to an adjusting rod 23 via a pin. A filter screen for filtering feces is provided between every two adjusting rods 23. A rectangular sleeve 24 that pushes the adjusting rod 23 to expand and contract is movably connected to the outer contour of the rotating rod 13 near the sleeve rod 12. The ends of the four adjusting rods 23 away from the first sliders 22 are rotatably connected to the rectangular sleeves 24 at corresponding positions via pins.

[0053] In use, the rectangular frame 21 on the processing box 1 and the first slider 22 on the rectangular frame 21 limit the movement of the first slider 22. The rectangular sleeve 24 on the rotating rod 13 moves the sleeve 12 closer to the cylindrical shell 4 along with the base 2, so that the sleeve 12 contacts the rectangular sleeve 24 and pushes the rectangular sleeve 24 to move synchronously. The adjusting rod 23 on the rectangular sleeve 24 rotates and connects the rectangular sleeve 24 and the first slider 22. Under the action of the rectangular sleeve 24, the adjusting rod 23 pushes the first slider 22 to move outward. The adjusting rod 23 is equipped with a filter screen to filter the feces. At this time, the feces are located at the bottom end of the rectangular frame 21 and the sewage is located at the top end of the rectangular frame 21 to prevent the feces and sewage at the bottom from mixing.

[0054] Example 5:

[0055] Building upon Example 4, the following is a further step:

[0056] A liquid storage tank 25 is fixedly connected to one side of the treatment tank 1. The top of the liquid storage tank 25 extends through to the inner wall and is fixedly connected to an inlet pipe 27 that collects the sewage inside the treatment tank 1 into the liquid storage tank 25. The end of the inlet pipe 27 away from the liquid storage tank 25 extends through to the inner wall of the treatment tank 1. A drain pipe 26 that discharges the sewage inside the liquid storage tank 25 is fixedly connected to one side of the liquid storage tank 25.

[0057] The separation mechanism includes a U-shaped frame 28 fixedly connected to the inner wall of the processing tank 1 at a position corresponding to the liquid inlet pipe 27, and a sealing plate 29 for sealing the liquid inlet pipe 27 is movably connected to the inner wall of the U-shaped frame 28. A connecting block 30 is provided on the sealing plate 29. A second slider 32 is movably connected to the inner wall of the rectangular frame 21 near the connecting block 30. A push rod 31 for pushing the sealing plate 29 to seal and release the seal of the liquid inlet pipe 27 is rotatably connected to the top of the second slider 32 via a pin. The end of the push rod 31 away from the second slider 32 is rotatably connected to the push rod 31 via a pin. A spring 33 for supporting the second slider 32 is fixedly connected to the opposite surface of the rectangular frame 21 on the side of the second slider 32 away from the first slider 22.

[0058] In use, the liquid storage tank 25 is provided on the processing box 1, and the drain pipe 26 is provided on the liquid storage tank 25, so the drain pipe 26 is connected to the liquid storage tank 25. The liquid inlet pipe 27 is provided on the liquid storage tank 25, so the processing box 1 and the liquid storage tank 25 are connected. The U-shaped frame 28 is provided on the processing box 1, and the sealing plate 29 is provided on the U-shaped frame 28, so that the movement of the sealing plate 29 is limited by the U-shaped frame 28, and the initial position of the sealing plate 29 seals the liquid inlet pipe 27.

[0059] As the adjusting rod 23 pushes the first slider 22 outward, the second slider 32 on the rectangular frame 21, and the spring 33 on the second slider 32, cause the first slider 22 to move into contact with the second slider 32 and push it towards the connecting block 30. The spring 33 is then compressed. Through the connecting block 30 on the sealing plate 29, and the push rod 31 rotatably connected to the connecting block 30 and the second slider 32, the push rod 31, under the action of the second slider 32, pushes the sealing plate 29 away from the rectangular frame 21. The rectangular frame 21 moves vertically. When the sealing plate 29 disengages from the inlet pipe 27, the sealing plate 29 releases the seal on the inlet pipe 27, allowing the inlet pipe 27 to draw sewage from the top of the rectangular frame 21 into the storage tank 25, further separating sewage and feces. At the same time, the drain pipe 26 transports the water inside the storage tank 25 to the biological filter, where the microorganisms attached to the packing material biodegrade organic matter, nitrogen, and phosphorus in the sewage. Simultaneously, the physical filtration of the packing material removes suspended solids, improving the quality of the effluent.

[0060] As the sewage flows out of the treatment tank 1, the air pressure inside the treatment tank 1 decreases. As a result, the piston plate 7 drives the screw 8 to move towards the rotating rod 13 to reset. The above structure moves synchronously under the action of the screw 8. Under the action of the rectangular sleeve 24, the adjusting rod 23 pulls the first slider 22 to retract inward, and the first slider 22 disengages from the second slider 32. Under the action of the spring force of the spring 33, the second slider 32 moves away from the connecting block 30 to reset. Then, the push rod 31 pulls the sealing plate 29 towards the rectangular frame 21, so that the sealing plate 29 can seal the liquid inlet pipe 27.

[0061] Example 6:

[0062] Building upon Example 5, the following is a further step:

[0063] The collection box 5 is equipped with a biogas internal combustion engine 10 that burns biogas to generate electricity. A concentration detector 9 for detecting biogas concentration is fixedly connected to the inner wall of the collection box 5, and the concentration detector 9 is connected to the biogas internal combustion engine 10. The processing box 1 is equipped with a storage battery 11 for storing the electrical energy generated by the biogas internal combustion engine 10, and the storage battery 11 is electrically connected to the biogas internal combustion engine 10.

[0064] In operation, the concentration detector 9 installed on the collection box 5 and the biogas internal combustion engine 10 are connected by signal, and the input terminal of the biogas internal combustion engine 10 is connected to the collection box 5. The biogas stored in the collection box 5 is sent to the generator set through the input terminal. The biogas enters the internal combustion engine and undergoes regulation, metering, and preheating. When the biogas concentration inside the collection box 5 reaches a certain level, the concentration detector 9 can start the biogas internal combustion engine 10, allowing the biogas internal combustion engine 10 to mix the biogas with air before processing. Combustion generates power, which drives the generator to rotate and produce electrical energy. This energy is then transmitted through a storage battery 11 installed on the processing box 1, and the storage battery 11 is electrically connected to the biogas internal combustion engine 10. This allows the biogas internal combustion engine 10 to store the electrical energy in the storage battery 11. The storage battery 11 is also connected to the lighting appliances in the ecological toilet, thereby powering the lighting appliances in the ecological toilet. This further improves the comprehensive utilization efficiency of biogas and increases the economic value of biogas. The biogas internal combustion engine 10 is an existing device, so it will not be described in detail here.

[0065] The main components of this device include a processing tank 1, a collection tank 5, a cylindrical shell 4, and a storage tank 25. The collection tank 5 and the storage tank 25 are bolted to the processing tank 1 for easy disassembly and replacement. The cylindrical shell 4 is connected to the processing tank 1 via a flange to ensure sealing and stability. A piston plate 7 and a screw 8 are installed between the processing tank 1 and the cylindrical shell 4 to buffer changes in internal gas pressure and prevent biogas leakage and explosion. A worm gear 16 and a worm wheel 17 are installed between the base 2 and the fixing block 15. The worm gear 16 is connected to the rotating rod 13 via a keyway to achieve synchronous rotation and torque transmission, which buffers the lifting and lowering movement of the base 2, reduces noise and vibration, and improves operational stability.

[0067] S1. Collect biogas: Collect the biogas inside the processing box 1 into the collection box 5 through the air inlet pipe 6;

[0068] S2, Stirring operation: The feces on the base 2 are stirred by the spiral blades 121;

[0069] S3, Lifting Operation: As the worm gear 17 drives the connecting rod 18 to rotate, the fixing block 15, under the support of the support rod 19, pushes the base 2 to move upward in the vertical direction closer to the cylindrical shell 4.

[0070] S4. Filtration operation: The first slider 22 is pushed outward by the adjusting rod 23 under the action of the rectangular sleeve 24, and a filter screen is provided on the adjusting rod 23 to filter the feces.

[0071] S5. Separation operation: The clearer sewage at the top of the rectangular frame 21 can be drawn into the storage tank 25 through the inlet pipe 27, which further realizes the separation of sewage and feces.

[0072] Furthermore, the existing device can collect biogas from the treatment tank, making it convenient to use and superior to traditional products.

[0073] The standard parts used in this embodiment can be purchased directly from the market, while the non-standard structural parts described in the specification and drawings can be processed directly based on existing technical knowledge without any doubt. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.

[0074] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
