The kitchen waste conveying structure is arranged between the oil-water separation device and the fermentation device 2 and is used to guide the kitchen waste separated by the oil-water separation device into the fermentation cavity of the fermentation device 2, and then the kitchen waste is degraded by microbial mixing to convert the kitchen waste into useful fertilizer or energy. Through this integrated design, the new kitchen waste treatment device can achieve efficient treatment of kitchen waste, improve the treatment efficiency, optimize the degradation conditions of microbial mixing, and thus realize a more environmentally friendly and sustainable garbage treatment method.

[0034] With such a design, the new kitchen waste treatment device can have the function of oil-water separation, effectively separating the oil and water in the kitchen waste.

[0039] Through this optimized layout design, the new kitchen waste treatment device not only improves the treatment efficiency but also simplifies the operation process, making the device more suitable for use in various environments and further promoting the environmental protection and sustainable development of kitchen waste treatment.

[0040] As Figures 1 to 12 shown, the fermentation device 2 of the present embodiment includes a fermentation tank 22, and the fermentation cavity 21 is located in the fermentation tank 22. The fermentation cavity is a space for carrying microbial mixtures and degrading kitchen waste. The fermentation cavity is located inside the fermentation tank. This design allows the fermentation process to be carried out in a controlled environment, which is conducive to maintaining appropriate temperature and humidity, thereby improving degradation efficiency.

[0041] Preferably, the fermentation tank 22 of the present embodiment is mechanically connected to the oil-water separation tank 11. The fermentation tank and the oil-water separation tank are fixed by bolts, buckles, hinges or other mechanical connectors. This design facilitates the disassembly and maintenance of the equipment, and also provides sufficient connection strength and sealing performance. The mechanical connection design makes the assembly and disassembly of the equipment simpler, which is convenient for daily maintenance and cleaning.

[0042] Preferably, in other embodiments, the fermentation tank 22 and the oil-water separation tank 11 are integrally formed. This design simplifies the manufacturing process of the equipment, enhances the stability and sealing performance of the structure, reduces potential leakage points at the connection, improves the reliability of the equipment, and ensures the compact structure of the equipment, which is convenient for installation and movement.

[0043] As Figures 1 to 12 shown, the fermentation device 2 of the present embodiment is mechanically connected to the oil-water separation device 1. The mechanical connection assembly includes a hinged member 10, which allows the oil-water separation device 1 to be flipped open on the fermentation device 2.

[0044] Preferably, the hinged member allows the oil-water separation device to rotate relative to the fermentation device 2, thereby achieving the opening and closing of the equipment. This design facilitates the cleaning, maintenance and inspection of the equipment by the user.

[0045] Through the hinged member, the user can easily flip open the oil-water separation device from the fermentation device 2, which makes it easier for the user to maintain and clean the oil-water separation device and the fermentation device 2. It is convenient to check and replace the internal filter or other components.

[0046] Preferably, the flip-open design reduces the number of components that need to be disassembled during maintenance, thereby simplifying the maintenance process. The user can perform necessary maintenance and cleaning without disassembling the entire equipment, which reduces the maintenance time.

[0047] As Figures 1 to 12As shown, the oil-water separation tank 11 of the present embodiment comprises a kitchen waste conveying part 111 and an oil-water guiding part 112, the kitchen waste separation chamber 13 is located in the kitchen waste conveying part 111, the oil-water separation tank 11 is provided with a kitchen waste output port 113, and the kitchen waste conveying structure 3 comprises conveying components 31 arranged in the kitchen waste conveying part 111, which can convey the kitchen waste in the kitchen waste separation chamber 13 to the kitchen waste output port 113.

[0048] The oil-water separation structure 14 comprises a filter assembly 141 arranged between the kitchen waste conveying part 111 and the oil-water guiding part 112, which can guide the oil-water in the kitchen waste conveying part 111 into the oil-water guiding part 112.

[0049] Specifically, the oil-water separation tank comprises a kitchen waste conveying part, which is provided with a kitchen waste separation chamber for temporarily storing kitchen waste and separating oil and water from the kitchen waste, and an oil-water guiding part for receiving the separated oil and water from the kitchen waste.

[0050] Specifically, conveying components are arranged in the kitchen waste conveying part, which can convey the kitchen waste in the kitchen waste separation chamber to the kitchen waste output port of the oil-water separation tank. The conveying components can be screw conveyors, conveyor belts or other mechanical conveying devices.

[0051] Preferably, a filter assembly is arranged between the kitchen waste conveying part and the oil-water guiding part, which can guide the oil-water in the kitchen waste conveying part into the oil-water guiding part and block the kitchen waste from entering the oil-water guiding part, thereby separating the oil and water.

[0052] Preferably, the filter assembly can comprise filter screens, sieve plates and other filter materials.

[0053] Operation process: The kitchen waste is first put into the kitchen waste separation chamber, and then pushed to the kitchen waste output port by the conveying components.

[0054] During the conveying process or the standing process of the kitchen waste, the filter assembly filters the kitchen waste and oil-water, and guides the oil-water to the oil-water guiding part, while the solid kitchen waste continues to be conveyed to the subsequent processing link.

[0055] By adopting the design of the synergistic effect of the conveying components and the filter assembly, the effective separation of oil and water in the kitchen waste can be achieved, the processing efficiency is improved, the design of the conveying components and the filter assembly makes the operation and maintenance more convenient, reduces the need for manual intervention, and enables the kitchen waste treatment equipment to realize automation.

[0056] Through this design, the new food waste treatment equipment not only improves the treatment efficiency, but also simplifies the operation process, making the equipment more suitable for use in various environments, and further promoting the environmental protection and sustainable development of food waste treatment.

[0057] Preferably, the fermentation device 2 of this embodiment is further provided with a food waste input port 23 corresponding to the food waste output port 113. The food waste input port 23 is the top inlet of the fermentation device 2, and the food waste output port 113 is the outlet of the oil-water separation device.

[0058] like Figures 1 to 12 As shown, the conveying component 31 of this embodiment includes a conveying screw 311 and a first driving assembly 312 , and the first driving assembly 312 is transmission-connected to the conveying screw 311 .

[0059] Preferably, the conveying component includes a conveying screw for transporting, lifting or compressing the food waste. In this application, the conveying screw is particularly suitable for sticky food waste because its spiral design can effectively push the waste to move along the axial direction of the screw.

[0060] Specifically, the first drive assembly is connected to the conveying screw and is responsible for providing power to rotate the conveying screw. The drive assembly can be an electric motor, which is connected to the conveying screw through a mechanical transmission device such as a belt, chain or gear.

[0061] Specifically, when the first drive component is started, it transmits power to the conveying screw, causing the conveying screw to start rotating. As the conveying screw rotates, the food waste in the food waste separation chamber is captured by the spiral blades and pushed forward, and finally transported to the food waste output port. The conveying screw can provide continuous and uniform material flow, which is crucial to maintaining the stability of the entire processing process.

[0062] like Figures 1 to 12 As shown, the oil-water separation box 11 of this embodiment is provided with a first door component, which includes a first door 115 and a second drive component 116. The second drive component 116 can drive the first door 115 to block or keep the first door 115 away from the food waste outlet 113.

[0063] Specifically, the oil-water separation box is provided with a first box door, which is a movable door component used to block or open the kitchen waste output port. The design of the first box door can be sliding, hinged or other mechanical structures to adapt to different operational requirements.

[0064] Specifically, the first door component also includes a second drive assembly, which is a power source for driving the first door to open or close, the second drive assembly can be an electric motor, pneumatic cylinder or hydraulic cylinder, connected to the first door through mechanical connection (such as connecting rod, gear or chain, etc.).

[0065] When it is necessary to prevent kitchen waste from spilling out of the output port or to maintain the sealing of the device, the second drive assembly will drive the first door to move to the blocking position, thereby closing the kitchen output port.

[0066] When it is necessary to transport kitchen waste to the next processing stage, the second drive assembly will move the first door away from the kitchen output port, thereby opening the output port and allowing kitchen waste to pass through.

[0067] Through the control of the second drive assembly, the opening and closing of the first door can be automated, reducing the need for manual operation and improving operational efficiency.

[0068] As Figures 1 to 12 shown, the oil-water separation tank 11 of the present embodiment is also provided with a door cleaning component, which includes a clean water output nozzle 117 and a second water supply assembly, the second water supply assembly is in communication with the clean water output nozzle 117, and the second water supply assembly can provide water to be sprayed out of the clean water output nozzle 117 to clean the surface of the first door 115.

[0069] Preferably, the door cleaning component includes one or more clean water output nozzles, which are located at appropriate positions of the oil-water separation tank 11 for spraying clean water to clean the surface of the door, the design of the nozzles can be fixed or adjustable to adapt to different sizes and shapes of the door.

[0070] Specifically, the door cleaning component also includes a second water supply assembly, which is a water supply system responsible for providing cleaning water, the second water supply assembly can include a water pump, a water tank, a pipeline system, etc., to ensure that clean water can be delivered to the clean water output nozzle.

[0071] When it is necessary to clean the first door, the second water supply assembly will start to deliver clean water to the clean water output nozzle through the pipeline, and the nozzle will then spray clean water to the surface of the first door to wash away residual kitchen waste and oil stains, etc. The cleaning operation can be automated through a pre-set program or sensor trigger; it can also be manual, started by the operator as needed.

[0072] The box door cleaning component ensures regular cleaning of the first box door surface, reduces the breeding of bacteria and odors, improves the hygiene standard of the equipment, the automatic cleaning system reduces the need for manual cleaning, saves labor costs, and improves cleaning efficiency. Regular cleaning and maintenance help to extend the service life of the equipment, reduce equipment failures caused by dirt accumulation, and effectively prevent the hardening of dried kitchen waste remaining on the first box door, which can hinder the closing of the first box door or cause the first box door to fail to seal the kitchen waste outlet 113.

[0073] As shown in Figures 1 to 12 , the second water supply assembly of the embodiment outputs hot water, which is convenient for cleaning oil stains on the surface of the first box door 115 and kitchen waste adhered to the surface of the first box door 115.

[0074] Preferably, the second water supply assembly not only includes a water pump, a water tank, and a pipeline system, but also integrates a heating device, which can be an electric heater, a steam heater, or other effective heating methods, for heating water to an appropriate temperature.

[0075] Specifically, the second water supply assembly can heat water to a specific temperature and then deliver it to the clean water output nozzle through the pipeline system. When the first box door needs to be cleaned, the heated hot water will be sprayed onto the surface of the first box door through the clean water output nozzle. The hot water can effectively dissolve oil stains and loosen adhered kitchen waste, thereby more thoroughly cleaning the first box door. The use of hot water can significantly improve the cleaning effect, especially when dealing with oil stains and strongly adhered kitchen waste, hot water can more quickly dissolve and remove these dirt.

[0076] The hot water cleaning system can reduce cleaning time and the amount of cleaning agent used, reduce cleaning costs and environmental impact, and effectively kill surface bacteria and microorganisms, further improving the hygiene standard of the equipment and meeting the strict requirements of the food processing and catering industry.

[0077] As shown in Figures 1 to 12 , the oil and water guide part 112 of the embodiment is located at the bottom of the kitchen waste conveying part 111. The filter assembly 141 includes a partition plate arranged between the kitchen waste conveying part 111 and the oil and water guide part 112 and a plurality of filter holes arranged on the partition plate. The oil and water in the kitchen waste conveying part 111 can flow into the oil and water guide part 112 through the filter holes.

[0078] Specifically, the oil and water guide part is located at the bottom of the kitchen waste conveying part and is a special area for collecting and separating oil and water. The part is designed with a separation device for collecting oil and water, which can be an oil-water separator or other effective separation equipment.

[0079] The kitchen waste conveying part is located above the oil-water guiding part, and is used for conveying the kitchen waste to a specific treatment area. The kitchen waste conveying part is provided with a conveying component 31 to reliably convey the kitchen waste.

[0080] Specifically, the filter assembly includes a partition plate arranged between the kitchen waste conveying part and the oil-water guiding part. The partition plate is mainly used for separating the kitchen waste and the liquid. The partition plate is provided with a plurality of filter holes. The size and distribution of the filter holes are accurately designed to allow the oil and water to pass through while blocking the larger solid kitchen waste. Through the filter holes, the liquid part such as oil and water can flow into the oil-water guiding part below, and the solid part remains in the kitchen waste conveying part.

[0081] During the kitchen waste conveying process, the solid waste moves in the conveying part, and the mixed liquid part such as oil and water flows into the oil-water guiding part through the filter holes on the partition plate.

[0082] Preferably, the liquid flowing into the oil-water guiding part is further separated into oil and water by sedimentation, gravity separation or other separation methods. The oil floats on the upper layer, and the water sinks on the lower layer, which facilitates subsequent treatment and discharge.

[0083] By arranging the filter assembly between the kitchen waste conveying part and the oil-water guiding part, solid-liquid separation is achieved, and the efficiency of oil-water separation is improved.

[0084] The design of the filter holes can effectively prevent larger solid particles from entering the oil-water guiding part, reduce the possibility of system blockage, and improve the stability and reliability of the equipment.

[0085] Through preliminary filtration and separation, the complexity and workload of subsequent treatment steps are reduced, and the operation efficiency of the entire system is improved.

[0086] As shown in Figures 1 to 12 The partition plate, the oil-water guiding part 112 and the kitchen waste conveying part 111 of the embodiment are integrally formed. Preferably, the integrally formed structure is usually made of corrosion-resistant and wear-resistant materials such as stainless steel, high-strength plastic or other materials suitable for food processing environment. The partition plate, the oil-water guiding part and the kitchen waste conveying part are integrated into one whole to ensure the consistency and strength of the structure.

[0087] The integrally formed structure reduces the joints and connection points, improves the sealing performance and durability of the structure, and simplifies the manufacturing and installation process.

[0088] In some embodiments, the separation plate, the oil-water guide 112, and the kitchen waste conveying part 111 are mechanically connected, and the mechanical connection structure is connected by bolts, welding, buckling, or other mechanical connection methods. The mechanical connection structure firmly connects the separation plate, the oil-water guide, and the kitchen waste conveying part together, provides certain flexibility, can quickly repair the damaged part of the oil-water separation tank, does not need to be replaced as a whole, is convenient to disassemble and maintain, and can also ensure the stability of the structure.

[0089] As shown in Figures 1 to 12 The oil-water guide 112 of the present embodiment includes an oil-water conveying tank located at the bottom of the kitchen waste conveying part 111. One end of the oil-water conveying tank is provided with a recovery assembly 119. The bottom of the oil-water conveying tank is provided with a certain slope. The oil-water in the oil-water conveying tank can flow to the recovery assembly 119 through the slope of the bottom of the oil-water conveying tank and the self-weight of the oil-water. The recovery assembly 119 collects and processes the oil-water.

[0090] Preferably, the oil-water guide includes an oil-water conveying tank located at the bottom of the kitchen waste conveying part. The tank is designed to collect the oil-water mixture flowing from the kitchen waste conveying part through the filter hole. The bottom of the oil-water conveying tank is designed with a certain slope. The slope design enables the oil-water to flow from high to low, i.e., in the direction of the recovery assembly, relying on its own gravity.

[0091] Preferably, the recovery assembly is located at one end of the oil-water conveying tank. Its structure is designed to effectively collect and process the oil-water flowing thereto. The oil-water naturally flows to the recovery assembly in the oil-water conveying tank through the slope of the bottom. The recovery assembly is responsible for separating and collecting the oil-water.

[0092] The slope design of the bottom of the oil-water conveying tank enables the oil-water to flow naturally without the need for additional power equipment, saving energy and reducing maintenance costs. The design of the recovery assembly ensures that the oil-water can be effectively separated and collected, improving the efficiency of oil-water separation.

[0093] Through the slope of the bottom of the oil-water conveying tank and the design of the recovery assembly, the efficiency of oil-water separation is significantly improved, and the oil-water can be separated and collected more quickly.

[0094] The compact design of the oil-water conveying tank and the recovery assembly saves equipment space, making the entire oil-water separation system more compact and easy to integrate into existing kitchen or food processing environments.

[0095] Preferably, the recovery assembly includes an oil-water separation valve. The oil-water separation valve can discharge the oil-water in the oil-water conveying tank to an oil-water collection tank in a kitchen waste treatment device or an external oil-water collection tank for collection. The appropriate design can be selected according to actual needs.

[0096] As Figures 1 to 12 shown, the oil-water separation tank 11 of the present embodiment is also provided with an oil-water separation tank cleaning component capable of cleaning the inside thereof, which comprises a plurality of water spray holes 1111 arranged at intervals on the inner side wall of the oil-water separation tank 11 and a first water body providing assembly 1112 in communication with the plurality of water spray holes 1111, the first water body providing assembly 1112 being capable of providing water body to be sprayed out of the water spray holes 1111 to clean the inner side wall of the oil-water separation tank 11.

[0097] Specifically, the oil-water separation tank is provided with a cleaning component specially used for cleaning to ensure that the inner wall and internal structure of the oil-water separation tank remain clean and avoid the accumulation of oil stains and the generation of odors.

[0098] The cleaning component comprises a plurality of water spray holes arranged at intervals on the inner side wall of the oil-water separation tank 11, and a first water body providing assembly in communication with the plurality of water spray holes, responsible for providing water body to the water spray holes, which can be a water pump or other water supply device, capable of ensuring sufficient water pressure and water volume.

[0099] When the oil-water separation tank 11 needs to be cleaned, the first water body providing assembly is started to provide water body to the plurality of water spray holes, and the water body is sprayed out of the water spray holes to form a high-pressure water flow to flush the inner side wall of the oil-water separation tank 11 opposite to the water spray holes, and the high-pressure water flow can effectively flush away the oil stains and impurities attached to the inner wall.

[0100] The flushed sewage will flow into the oil-water conveying tank through the filter holes on the partition plate, or be discharged through the specially designed sewage discharge port, to ensure that the oil-water separation tank 11 remains clean.

[0101] By providing the cleaning component, the automatic cleaning of the oil-water separation tank 11 is realized, reducing the workload and difficulty of manual cleaning.

[0102] The design of the plurality of water spray holes and the first water body providing assembly ensures efficient cleaning effect, which can quickly remove oil stains and maintain the clean state of the oil-water separation tank.

[0103] As Figures 1 to 12 shown, the first water body providing assembly 1112 of the present embodiment outputs hot water, which is convenient for cleaning the oil stains on the inner side wall of the oil-water conveying tank and the kitchen waste adhered to the surface of the inner side wall of the oil-water conveying tank.

[0104] Specifically, hot water can more effectively dissolve and remove oil stains, especially for the oil and kitchen waste attached to the inner side wall of the oil-water conveying tank. Hot water has a certain sterilization effect, which can reduce the breeding of bacteria and microorganisms, maintain the hygiene of the oil-water separation tank, and accelerate the decomposition and softening of oil, making the cleaning process more rapid and thorough.

[0105] Specifically, the first water body providing assembly not only provides water body, but also outputs hot water. The first water body providing assembly comprises a heating device, such as an electric heater or other heating system, to ensure that the water body reaches a suitable temperature.

[0106] When the oil-water conveying tank needs to be cleaned, the first water body providing assembly is started to output hot water to the plurality of water spray holes. The hot water is sprayed out through the water spray holes to wash the inner side wall of the oil-water conveying tank. The impact force and temperature of the hot water can effectively remove oil stains and kitchen waste.

[0107] As shown in Figures 1 to 12 The fermentation device 2 of the embodiment further comprises a stirring structure, which can stir the microbial mixture and / or kitchen waste in the fermentation cavity 21. The stirring structure comprises a stirring shaft assembly 24 and a third driving assembly 25, which is in transmission connection with the stirring shaft assembly 24.

[0108] Specifically, the fermentation device 2 comprises a stirring structure designed to stir the microbial mixture and / or kitchen waste in the fermentation cavity to promote uniform mixing and sufficient contact, thereby improving the fermentation efficiency.

[0109] The stirring structure comprises a stirring shaft assembly and a third driving assembly in transmission connection with the stirring shaft assembly to provide power to drive the stirring shaft assembly to rotate.

[0110] During the fermentation process, the third driving assembly is started to drive the stirring shaft assembly to rotate through transmission connection, thereby stirring the microbial mixture and kitchen waste in the fermentation cavity. The stirring structure functions to uniformly mix the microbial mixture and kitchen waste in the fermentation cavity, ensuring sufficient contact between the microorganisms and the kitchen waste and promoting the fermentation reaction.

[0111] The stirring structure can effectively promote the uniform mixing of the microbial mixture and kitchen waste, improve the mass transfer efficiency during the fermentation process, thereby accelerating the fermentation process. Stirring can also prevent the microbial mixture and kitchen waste from precipitating in the fermentation cavity, maintain uniform distribution of substances in the fermentation cavity, and avoid local over-concentration or dilution.

[0112] Preferably, when the kitchen waste is not put in, and the microorganism and the various mixed materials have been put in, the stirring structure starts the stirring cycle mode, first, it rotates forward for a period of time, such as three to five minutes, then it pauses for a period of time, such as fifteen to thirty seconds, then it rotates reversely for a period of time, such as three to five minutes, then it pauses for a period of time, such as fifteen to thirty seconds, then it rotates forward for a period of time, such as three to five minutes, and finally it stops for a period of time, such as twenty minutes to twenty-five minutes, this process is a cycle of the stirring cycle, in this way, the microorganism and the various mixed materials can be mixed better to form the microorganism mixed material, and during the stirring process, the moisture in the microorganism mixed material can be effectively discharged to ensure the activity of the microorganism.

[0113] Preferably, by using this forward and reverse rotation stirring method, the accumulation of too much microorganism mixed material at one end of the fermentation tank can be avoided, and the uniform mixing and uniform distribution of the microorganism mixed material in the fermentation tank can be ensured.

[0114] Preferably, after the microorganism and the mixed material are put into the fermentation tank for a period of time, about twenty-four hours later,

[0115] The kitchen waste can be put into the kitchen waste treatment equipment, and then the kitchen waste after the oil-water separation process enters the fermentation tank, the stirring method is similar to the above-mentioned stirring cycle mode, by using this forward and reverse rotation stirring method, the accumulation of too much microorganism mixed material and kitchen waste at one end of the fermentation tank can be avoided, and the uniform mixing of the microorganism mixed material and the kitchen waste can be ensured, and the degradation effect of the microorganism can be improved.

[0116] Preferably, the stirring structure stops stirring to provide sufficient time for the microorganism mixed material to degrade the kitchen waste, and by using this stirring cycle mode, the kitchen waste and the microorganism mixed material can be stirred in time to discharge moisture, and the environment for the microorganism can always be kept in a suitable humidity environment.

[0117] As shown in the figure, Figures 1 to 12 The stirring shaft assembly 24 of the embodiment includes a main shaft 241 connected in transmission with the third driving assembly 25, and a plurality of first auxiliary shafts 242 spirally distributed along the shaft body of the main shaft 241.

[0118] Preferably, the stirring shaft assembly includes a main shaft connected in transmission with the third driving assembly, which is the main rotating component of the stirring shaft assembly, and a plurality of first auxiliary shafts spirally distributed along the shaft body of the main shaft, the design of the first auxiliary shaft increases the contact area and the stirring effect, so that the stirring is more uniform and efficient.

[0119] Specifically, the third driving assembly is started, and the main shaft is driven to rotate through the transmission connection. The rotation of the main shaft drives the whole stirring shaft assembly to rotate. With the rotation of the main shaft, the first auxiliary shaft distributed spirally along the main shaft also rotates. The design of the first auxiliary shaft enables the stirring blades or stirring arms to more effectively stir the kitchen waste and / or microbial mixture, promoting uniform mixing and sufficient contact.

[0120] Specifically, through the cooperation of the main shaft and the first auxiliary shaft, the stirring shaft assembly can more effectively stir the substances in the fermentation cavity, improving the stirring efficiency and fermentation effect.

[0121] Specifically, the first auxiliary shaft is arranged in this way, which can reduce the pressure of the mixture on the first auxiliary shaft. Compared with the existing design of the first auxiliary shaft with spiral whole blades, the design of the plurality of first auxiliary shafts arranged at intervals can effectively reduce the load of the mixture on the first auxiliary shaft without affecting the conveying and stirring functions of the stirring structure, prolonging the service life of the first auxiliary shaft.

[0122] Preferably, the design of the stirring shaft assembly facilitates disassembly and maintenance, allowing regular inspection and replacement of the first auxiliary shaft to ensure the stirring effect and equipment life.

[0123] As shown in Figures 1 to 12 the first auxiliary shaft 242 of the present embodiment includes a shaft body 2421 and a paddle 2422 arranged on one end of the shaft body 2421. The other end of the shaft body is connected with the main shaft 241, and the paddle 2422 has a certain curvature.

[0124] The first auxiliary shaft includes a shaft body and a paddle arranged on one end of the shaft body. The paddle is used to stir the material in the fermentation cavity. The design of the paddle is usually to maximize the stirring effect, and the paddle body has a certain curvature, which helps to provide greater stirring force and better fluid dynamics.

[0125] Preferably, the other end of the shaft body is connected with the main shaft. This connection can be welding, threaded connection or other types of mechanical connection, which ensures that the first auxiliary shaft is stable during stirring and can withstand the force caused by stirring. Through the paddle on the first auxiliary shaft, the substances in the fermentation cavity can be more effectively stirred, thereby accelerating the fermentation process. The arc-shaped paddle is usually more efficient, which can provide strong stirring action while consuming less energy.

[0126] As shown in Figures 1 to 12As shown, the paddle 2422 of this embodiment is in the shape of a shovel, which is similar to a shovel used in gardening tools, with a wide shovel surface and a certain curvature. This design helps to better push and turn the materials during the stirring process, similar to the action of a shovel digging in the soil, thereby promoting the circulation and mixing of the materials in the fermentation chamber. The wide shovel surface and curvature of the paddle enable it to turn the materials, turning the materials at the bottom to the surface, or pushing the materials on the surface to the bottom, so as to achieve uniform distribution and sufficient contact of the materials.

[0127] like Figures 1 to 12 As shown, two oppositely arranged second sub-shafts 243 are also provided on the main shaft 241 of this embodiment. The two second sub-shafts 243 are located at both ends of the main shaft 241 and close to the inner wall of the fermentation chamber 21. This arrangement helps to directly act on the edge area of ​​the fermentation chamber. These areas are usually dead corners for stirring and are prone to material accumulation.

[0128] Preferably, the second sub-shaft 243 of this embodiment is T-shaped. The T-shaped second sub-shaft 243 has a larger stirring range. The T-shaped second sub-shaft 243 can stir and transport kitchen waste and / or humus fertilizer in the dead corners at both ends of the fermentation box, thereby preventing kitchen waste and / or humus fertilizer from accumulating at both ends of the fermentation box.

[0129] Since a large amount of material usually accumulates at the corners of the inner walls at both ends of the fermentation chamber, the secondary shaft with a paddle body having a certain curvature usually cannot stir the material there. In fact, due to the weight of the material, the paddle blades 2422 on the secondary shaft are damaged. Or, for the design in which the secondary shaft is detachably connected to the main shaft, the secondary shaft is more easily affected by the weight of the material on the main shaft, resulting in positional displacement or detachment of the secondary shaft from the main shaft, affecting the normal operation of the secondary shaft.

[0130] Preferably, the T-shaped secondary shaft is more evenly stressed, reducing the stress concentration caused by single-point stress, thereby reducing the risk of damage to the secondary shaft and making it less prone to damage. With regard to the design in which the second secondary shaft 243 is detachably connected to the main shaft, the secondary shaft is not easily affected by the weight of the material on the main shaft, and position displacement or falling off of the secondary shaft occurs, thereby ensuring the normal operation of the secondary shaft.

[0131] like Figures 1 to 12 As shown, the fermentation box 22 of this embodiment is provided with an air inlet 221 and an exhaust port 222 respectively connected to the fermentation chamber 21. The fermentation device 2 also includes an air filtration system 4 connected to the exhaust port 222. The air filtration system 4 can process the gas discharged from the fermentation chamber 21 to meet the emission requirements.

[0132] Specifically, the fermentation tank is provided with an air inlet communicated with the fermentation cavity for providing fresh air into the fermentation cavity to support the activity of microorganisms and promote the fermentation process. The fermentation tank is also provided with an air outlet for discharging the gas generated in the fermentation process, including carbon dioxide, water vapor and possible volatile organic compounds.

[0133] The fermentation device 2 further comprises an air filtering system connected with the air outlet, which is responsible for treating the gas discharged from the fermentation cavity. The air filtering system can filter and treat the gas discharged from the fermentation cavity to remove harmful substances such as odor, particulate matter, volatile organic compounds, etc. to meet the environmental emission requirements.

[0134] As shown in Figures 1 to 12 The air filtering system 4 of the embodiment comprises a gas disinfection component 41 and a gas filtering component 42 connected in sequence. The gas filtering component 42 comprises a gas filtering box 421 and a gas filtering member 422 arranged in the gas filtering box 421. The gas disinfection component 41 comprises a gas disinfection box 411 and a gas disinfection assembly 412 arranged in the gas disinfection box 411. The air outlet 222 is connected with the gas disinfection assembly 412. The gas filtering box 421 is provided with a gas discharge port 423.

[0135] By arranging the gas disinfection component and the gas filtering component, the air filtering system can provide multiple protection to ensure the safety and cleanliness of the discharged gas. Combined with the disinfection and filtering functions, the system can efficiently treat various harmful gases and microorganisms generated in the fermentation process, improve the environmental performance of the entire fermentation system, and the modular design of the gas disinfection box and the gas filtering box facilitates the maintenance and replacement of components, improving the operation convenience and maintainability of the system.

[0136] As shown in Figures 1 to 12 The gas disinfection box 411 of the embodiment comprises a first disinfection part 4111. The gas disinfection assembly 412 comprises a plurality of UV lamps arranged at intervals in the first disinfection part 4111. The UV lamps can effectively kill bacteria, viruses and other microorganisms in the gas by emitting ultraviolet rays.

[0137] The gas generated in the fermentation process first enters the gas disinfection box through the air outlet. When the gas enters the first disinfection part and passes through the plurality of UV lamps arranged at intervals, the ultraviolet rays can penetrate the cell walls of the microorganisms in the gas, damage their DNA and RNA structures, and thus kill these microorganisms. The pathogenic organisms are effectively eliminated after the gas is treated by the UV lamps, improving the cleanliness of the gas. The disinfected gas will continue to enter the gas filtering component for further treatment.

[0138] Preferably, the UV lamps can directly act on the microorganisms through ultraviolet rays to quickly and efficiently kill bacteria, viruses and other harmful microorganisms in the gas.

[0139] Preferably, the plurality of spaced UV lamps are designed for easy maintenance and replacement, ensuring the continuity and reliability of the disinfection effect, and through the joint action of multiple UV lamps, ensuring that the gas in the gas disinfection tank can be fully exposed to ultraviolet light, achieving the effect of thorough disinfection.

[0140] Preferably, ultraviolet disinfection is a physical treatment method that does not introduce chemical reagents, avoiding secondary pollution and meeting environmental protection requirements.

[0141] As shown in Figures 1 to 12 The gas disinfection tank 411 of the embodiment further includes a second disinfection part 4112, the first disinfection part 4111 and the second disinfection part 4112 are arranged adjacent to each other, and the gas disinfection assembly 412 further includes an ozone disinfection assembly arranged in the second disinfection part 4112.

[0142] Specifically, the second disinfection part is arranged adjacent to the first disinfection part and is another part of the gas disinfection tank, and is internally provided with an ozone disinfection assembly for further disinfection treatment of the gas.

[0143] Specifically, the ozone disinfection assembly is arranged in the second disinfection part and disinfects the gas by generating ozone, which is a strong oxidizing agent capable of destroying the cell wall and cell membrane of microorganisms and killing bacteria, viruses, fungi and spores, etc.

[0144] The gas generated in the fermentation process first enters the gas disinfection tank through the exhaust port, enters the second disinfection part, and is further disinfected by the ozone generated by the ozone disinfection assembly. Ozone can oxidize organic and inorganic pollutants in the gas, kill residual microorganisms, and remove odors.

[0145] Preferably, the gas can first enter the first disinfection part and then flow into the second disinfection part, or first enter the second disinfection part and then flow into the first disinfection part. The appropriate design can be selected according to actual needs.

[0146] Specifically, the gas that has been disinfected by ultraviolet light and ozone has effectively eliminated pathogens, improving the cleanliness of the gas. The disinfected gas will continue to enter the gas filtration part for further treatment.

[0147] As shown in Figures 1 to 12 The gas disinfection assembly 412 of the embodiment further includes a high-temperature disinfection assembly arranged in the second disinfection part 4112, which achieves the effect of high-temperature disinfection by heating the gas. High temperature can denature the proteins of microorganisms, thereby killing bacteria, viruses and other pathogens.

[0148] The gas generated in the fermentation process first enters the gas sterilization tank through the exhaust port. Preferably, in the present embodiment, the gas first enters the first sterilization part, and when passing through the multiple UV lamps arranged at intervals, the ultraviolet rays can penetrate the cell walls of the microorganisms in the gas, destroy the DNA and RNA structures, and thus kill these microorganisms.

[0149] The gas sterilized by the ultraviolet rays continues to enter the second sterilization part, and the gas is heated to a high enough temperature by the high-temperature sterilization assembly to further kill the microorganisms in the gas. After high-temperature sterilization, the gas continues to pass through the ozone sterilization assembly, and ozone can further oxidize and sterilize organic and inorganic pollutants in the gas, kill residual microorganisms, and remove odors.

[0150] The gas sterilized by the ultraviolet rays, high temperature, and ozone has the pathogenic organisms effectively eliminated, and the cleanliness of the gas is improved. The sterilized gas will continue to enter the gas filtration component for further processing.

[0151] The ultraviolet rays, high temperature, and ozone provide comprehensive sterilization effects for different types of microorganisms and pollutants.

[0152] Preferably, the gas can first enter the first sterilization part and then flow into the second sterilization part, or first enter the second sterilization part and then flow into the first sterilization part. The appropriate design can be selected according to actual needs, and the sterilization sequence can also be selected according to actual needs. This will not be described here.

[0153] As shown in Figures 1 to 12 The gas sterilization tank 411 is provided with a partition tank body 4113, which divides the gas sterilization tank 411 into a first sterilization part 4111 and a second sterilization part 4112. The side wall of the partition tank body 4113 is provided with a gas through hole 4114, which communicates with the first sterilization part 4111 and the second sterilization part 4112, respectively.

[0154] Specifically, the partition tank body 4113 is arranged inside the gas sterilization tank and is used to divide the gas sterilization tank into two independent sterilization parts, i.e., the first sterilization part and the second sterilization part. The side wall of the partition tank body is provided with a gas through hole for allowing the gas to flow from the first sterilization part to the second sterilization part.

[0155] The gas generated in the fermentation process first enters the gas sterilization tank through the exhaust port. The gas enters the first sterilization part, and when passing through the multiple UV lamps arranged at intervals, the ultraviolet rays can penetrate the cell walls of the microorganisms in the gas, destroy the DNA and RNA structures, and thus kill these microorganisms. The gas sterilized by the ultraviolet rays enters the second sterilization part through the gas through hole on the side wall of the partition tank body. After the gas enters the second sterilization part, the gas is heated to a high enough temperature by the high-temperature sterilization assembly to further kill the microorganisms in the gas,

[0156] After high-temperature disinfection, the gas continues to pass through the ozone disinfection assembly, and ozone can further oxidize and disinfect organic and inorganic pollutants in the gas, kill residual microorganisms, and remove odors.

[0157] After multiple disinfection processes, pathogens are effectively eliminated, and the cleanliness of the gas is improved. The disinfected gas will continue to enter the gas filtration component for further processing.

[0158] By designing a partitioned box, the gas disinfection box is divided into two independent disinfection parts, so that the gas can be sequentially processed between different disinfection parts, ensuring that the disinfection effect is maximized, and the structure of the gas disinfection box is more compact.

[0159] The triple disinfection mechanism of ultraviolet light, high temperature, and ozone ensures the thoroughness and efficiency of gas disinfection.

[0160] As shown in Figures 1 to 12 The gas disinfection box 411 of the present embodiment is provided with a gas inlet 4115 and a gas outlet 4116, the gas inlet 4115 communicates with the first disinfection part 4111, and the gas outlet 4116 communicates with the second disinfection part 4112, or the gas inlet 4115 communicates with the second disinfection part 4112, and the gas outlet 4116 communicates with the first disinfection part 4111.

[0161] Preferably, the gas disinfection box 411 can have multiple configurations:

[0162] The first configuration: the gas enters the first disinfection part through the gas inlet, the gas enters the first disinfection part, and is disinfected by multiple UV lamps arranged at intervals, the gas disinfected by ultraviolet light passes through the gas through-hole on the side wall of the partitioned box, enters the second disinfection part, and after the gas enters the second disinfection part, the gas is heated to a high enough temperature by the high-temperature disinfection assembly, further killing microorganisms in the gas, after high-temperature disinfection, the gas continues to pass through the ozone disinfection assembly, and ozone can further oxidize and disinfect organic and inorganic pollutants in the gas, kill residual microorganisms, and remove odors, the gas disinfected by multiple disinfection processes is discharged from the gas outlet of the disinfection box.

[0163] The second configuration: the gas enters the second disinfection section through the gas inlet. The gas first enters the second disinfection section and is heated to a sufficiently high temperature by the high-temperature disinfection component to kill the microorganisms in the gas. After high-temperature disinfection, the gas continues to pass through the ozone disinfection component. Ozone can further oxidize and disinfect the organic and inorganic pollutants in the gas, kill the residual microorganisms, and remove odors. The gas that has been dual-sterilized by high temperature and ozone enters the first disinfection section through the gas through-holes on the side wall of the partition box. When the gas enters the first disinfection section and passes through multiple UV lamps set at intervals, the ultraviolet rays can penetrate the cell walls of the microorganisms in the gas and destroy their DNA and RNA structures, further ensuring the cleanliness of the gas. The gas that has undergone multiple disinfection treatments is discharged from the disinfection box from the gas outlet.

[0164] There are also various configurations where the positions of the high-temperature disinfection component and the ozone disinfection component are interchanged, which will not be described here.

[0165] The settings of the gas inlet and gas outlet can be flexibly configured according to actual needs, allowing the gas to pass through which disinfection part first, thereby improving the adaptability of the system.

[0166] like Figures 1 to 12 As shown, the gas filter box 421 of this embodiment includes an outer box 424 and an inner box 425 arranged in the outer box 424, and a heat dissipation gap 426 is provided between the outer box 424 and the inner box 425. The outer box 424 is provided with an air outlet 4241 and an assembly port 4242. One end of the inner box 425 extends to the outside of the assembly port 4242 and is connected to the output end of the gas disinfection component 41.

The inner box is arranged inside the outer box and actually accommodates the part of the gas filter component. One end of the inner box extends to the outside of the air inlet of the outer box and is connected to the output end of the gas disinfection component. The other end of the inner box extends to the inside of the outer box and is arranged corresponding to the air inlet.

[0168] Specifically, the heat dissipation gap is the space between the outer box and the inner box, which is used to dissipate heat and prevent the internal temperature from being too high to affect the filtering effect.

[0169] Specifically, the gas is sterilized by the gas sterilization component, and the sterilized gas enters the gas filter box through one end of the inner box connected to the output end of the gas sterilization component. The gas passes through the activated carbon filter in the inner box, which can adsorb organic matter, odor and other impurities in the gas, further purify the gas, and the filtered gas is discharged through the other end of the inner box and enters the outer box. The gas filtered by the inner box is discharged through the air outlet of the outer box, completing the entire filtering process.

[0170] Specifically, during the gas filtering process, the heat dissipation gap effectively dissipates heat through natural convection or auxiliary heat dissipation, preventing the internal temperature of the inner box from being too high and ensuring the normal operation and long service life of the filter assembly.

[0171] Specifically, the activated carbon filter can effectively adsorb and remove organic matter, odor and other impurities in the gas, significantly improving the cleanliness of the gas. Through the structural design of the outer box and the inner box and the heat dissipation gap between them, the heat dissipation effect of the gas filter box is ensured, preventing overheating from affecting the filtering effect.

[0172] Specifically, one end of the inner box extends to the outside of the air inlet and is connected to the gas sterilization component, ensuring that the sterilized gas directly enters the filter box and improving the overall efficiency of the system.

[0176] When it is necessary to adjust the humidity inside the fermentation box, the heating component is started, and the heating component heats the fermentation box. The temperature rise causes the moisture inside the fermentation box to evaporate, and the evaporated moisture reduces the humidity inside the fermentation box, thereby meeting the preset humidity requirement.

[0177] Preferably, a humidity sensor can be used to monitor the humidity inside the fermentation box in real time, and the working state of the heating component can be adjusted by the control system to ensure that the humidity is maintained within the ideal range.

[0184] Hot air circulation system: heats air by heating elements and circulates hot air into the fermentation tank using a fan, which can quickly heat and uniformly distribute heat to improve heating efficiency.

[0185] Infrared heater: transmits heat to the fermentation tank by infrared radiation, which has penetrating properties and can directly heat the contents in the fermentation tank.

[0186] The appropriate design can be selected according to actual needs.

[0193] Specifically, the second tank door component controls the opening and closing of the second tank door through the fourth driving assembly.

[0194] When the material needs to be discharged, the fourth driving assembly drives the second tank door to move away from the total discharge port, so that the total discharge port is opened and the material can be discharged.

[0195] When the material does not need to be discharged, the fourth driving assembly drives the second tank door to block the total discharge port to prevent the material from being discharged.

The design of the opening at the top of the collection tank simplifies the discharge and collection process of the material, reduces the complex mechanism, and the user only needs to take away the collection tank 271 containing the collected kitchen waste to complete the collection, which has the advantages of simple structure and convenient operation.

[0200] As shown in Figures 1 to 12 The collecting assembly 27 of the embodiment further comprises a guide plate 272 arranged on one side of the fermentation tank 22. The guide plate 272 has a certain slope and can guide the material discharged from the total discharge port 26 to the collecting tank 271. With such a design, the kitchen waste can accurately fall into the collecting tank 271 from the total discharge port 26, ensuring the scattering of the kitchen waste, keeping the working environment clean, and accurately collecting the kitchen waste.

[0208] Preferably, the light can also assist in adjusting the temperature in the fermentation tank. By controlling the light, the humidity in the fermentation tank can be indirectly affected, the stability of the fermentation environment can be maintained, and a suitable fermentation environment can be provided.

[0209] As shown in Figures 1 to 12 The simulated sunlight device of the embodiment comprises a fermentation lamp 61, which has the advantages of simple structure, convenient operation, and low cost.

[0210] As shown in Figures 1 to 12As shown, the fermentation lamp 61 of this embodiment is located outside the fermentation box 22 , and the simulated sunlight device further includes a light-transmitting window 62 provided on the top of the fermentation box 22 , and the light-transmitting window 62 is provided corresponding to the fermentation lamp 61 .
