Description

Technical Field

[0001] This invention belongs to the field of carbon source preparation technology, specifically to a device for continuously preparing carbon sources using kitchen waste. Background Technology

[0002] With the acceleration of urbanization, the demand for food waste treatment is constantly increasing. In order to reduce the pollution of food waste to the environment and improve the reuse of food waste, existing methods use food waste to prepare carbon sources, which can realize the resource utilization of food waste and save waste treatment costs.

[0003] When using a fermentation tank to ferment pre-treated kitchen waste to prepare a carbon source, the pre-treated kitchen waste is first poured into the feed hopper of the fermentation tank, then enters the tank. Simultaneously, microorganisms are added, and the stirring components are activated to thoroughly mix the microorganisms and kitchen waste for fermentation. During fermentation, the microorganisms decompose the organic matter in the kitchen waste, producing large amounts of carbon dioxide and methane gases. The accumulation of these gases increases the pressure inside the fermentation tank. After microorganisms and kitchen waste are processed, the exhaust pipe installed on it is used to periodically ventilate and remove the gas accumulated in the fermentation tank to ensure the safety of the fermentation tank. However, during the venting process, due to the high pressure inside the fermentation tank, the fermented material inside can easily splash onto the vent outlet of the exhaust pipe. As a result, after long-term use, the vent outlet can become blocked, affecting the venting of the fermentation tank and causing excessive internal pressure, which poses a certain safety hazard. Therefore, the fermentation tank needs to be shut down after a period of use, and the exhaust pipe needs to be cleaned by maintenance personnel, which increases the cost of producing carbon sources from kitchen waste. Utility Model Content

[0004] To address the problems of existing fermentation tanks being prone to clogging of the exhaust pipe during long-term use, leading to safety accidents and high costs associated with preparing carbon sources from kitchen waste, this invention provides a device for the continuous preparation of carbon sources from kitchen waste.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] This utility model proposes a device for continuously producing carbon sources from kitchen waste, including a fermentation component, an exhaust pipe on the fermentation component, and a cleaning section on the exhaust pipe;

[0007] An annular block is provided inside the exhaust pipe, and a push rod is movably installed in the annular block along its radial direction. A reset member is sleeved on the push rod, and one end of the reset member is connected to the push rod. An exhaust hole is provided on the exhaust pipe corresponding to the position of the push rod.

[0008] The cleaning unit includes a hollow slide barrel, the bottom of which passes through the annular block. An outer scraper frame is connected to the hollow slide barrel, and the bottom of the outer scraper frame is fitted onto the exhaust pipe.

[0009] A telescopic component is installed inside the hollow slide barrel. One end of the telescopic component is fixed to the exhaust pipe, and the other end of the telescopic component is connected to the top of the hollow slide barrel. The telescopic component allows the outer scraper frame to slide along the exhaust pipe, and the bottom of the hollow slide barrel pushes the top rod into the exhaust hole for sealing.

[0010] Preferably, the inner end face of the push rod is set as an inclined surface, and the bottom end of the hollow slide is provided with a trapezoidal platform. When the hollow slide pushes the push rod, the outer wall of the trapezoidal platform fits against the inclined surface.

[0011] Preferably, a roller is rotatably mounted on the inclined surface of the top rod.

[0012] Preferably, the bottom of the trapezoidal platform is provided with an inner scraper frame, and the outer wall of the inner scraper frame is in contact with the inner wall of the exhaust pipe.

[0013] Preferably, the telescopic component is an electric telescopic rod.

[0014] Preferably, the reset element is a spring.

[0015] Preferably, a reinforcing rod is provided at the connection between the telescopic component and the hollow slide.

[0016] Preferably, the fermentation assembly includes a fermentation tank with a discharge pipe, a tank cover connected to the top of the fermentation tank, a feed inlet on the tank cover, a feed hopper installed on the feed inlet, and a protective part installed on the feed hopper; a stirring drive is installed on the side of the tank cover located at the feed inlet, a stirring part is connected to the stirring drive, and the stirring part is installed inside the fermentation tank;

[0017] The tank lid is provided with an exhaust port on the side of the stirring drive, and the exhaust pipe is installed on the exhaust port.

[0018] Preferably, the protective part includes a protective cover, on which a round shaft is provided, and a protrusion is provided on the feed hopper at its port position, the protrusion being rotatably connected to the round shaft.

[0019] Preferably, the protective cover is provided with a handle block.

[0020] Compared with the prior art, the present invention has the following beneficial technical effects:

[0021] This invention proposes a device for continuously producing carbon sources from kitchen waste. The device uses a telescopic component in the cleaning section to move a hollow slide bucket downwards within a circular block in the exhaust pipe. This pushes a push rod outwards, inserting it into several exhaust holes on the exhaust pipe to block them and seal the exhaust pipe. Simultaneously, a reset component extends. When exhaust is needed, the telescopic component moves the hollow slide bucket upwards within the circular block in the exhaust pipe. Under the action of the reset component, one end of the push rod returns to its original position and slides out of the exhaust hole, thus venting the gas in the fermentation tank. If some fermented material splashes into the exhaust holes during venting, the push rod can push the splashed fermented material out of the inner wall of the exhaust hole when the exhaust holes are closed next time, cleaning it out. This avoids clogging of the exhaust holes, improves the venting effect and efficiency, and reduces potential safety hazards.

[0022] Furthermore, in this device, a trapezoidal platform is provided at the bottom end of the hollow slide barrel through the inclined surface of the inner end of the top surface, which allows the hollow slide barrel to stably push the push rod as it slides downward in the air outlet, thus ensuring the stability of the device's operation.

[0023] Furthermore, rollers are rotatably mounted on the inclined surface of this device. The rollers reduce the friction between the inclined surface of the push rod and the bottom end face of the hollow slide, making the hollow slide push the push rod more smoothly and improving the service life of both.

[0024] Furthermore, a reinforcing rod is provided at the connection between the telescopic component and the hollow slide in this device. The reinforcing rod strengthens the connection between the telescopic component and the hollow slide, making the connection between the telescopic component, the hollow slide, and the outer scraper frame more secure and stable, and less prone to damage.

[0025] Furthermore, the feed hopper in this device is equipped with a protective part, which includes a protective cover. The protective cover seals the top port of the feed hopper to prevent external impurities from entering the feed hopper and thus avoid affecting its later use. Attached Figure Description

[0037] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0038] See Figures 1-5 This invention proposes a device for continuously generating carbon sources from kitchen waste, comprising a fermentation assembly, which includes a fermentation tank 1 and a tank cover 4. A discharge pipe 6 is provided on the outer surface of the fermentation tank 1. The tank cover 4 is located at the top port of the fermentation tank 1, and a feed inlet is provided on the top end face of the tank cover 4. A feed hopper 7 is connected to the feed inlet, meaning the feed hopper 7 communicates with the interior of the fermentation tank 1 through the feed inlet. A stirring drive is installed on the top end face of the tank cover 4, located on the side of the feed inlet. The output shaft of the stirring drive extends into the fermentation tank 1, and a stirring device is connected to the output shaft of the stirring drive. The mixing unit is installed inside the fermentation tank 1. The mixing unit stirs the kitchen waste in the fermentation tank 1 to accelerate the fermentation of the kitchen waste in the fermentation tank 1. An exhaust port is provided on the top end face of the tank cover 4, located on the side of the mixing drive component. An exhaust pipe 5 is installed on the exhaust port. A cleaning unit 2 is installed on the top of the exhaust pipe 5 to clean the exhaust pipe 5 and prevent the exhaust pipe 5 from becoming blocked. A protective unit 3 is provided on one side of the feed hopper 7 at its port position to prevent external debris from entering the fermentation tank 1 from the feed hopper 7 and affecting the fermentation of the kitchen waste in the fermentation tank 1.

[0039] The cleaning section 2 includes a circular ring block 21 and a hollow slide 25. One side of the circular ring block 21 is fixedly connected to the top end face of the interior of the exhaust pipe 5, and the circular ring block 21 and the exhaust pipe 5 are concentrically arranged. Several push rods 22 are connected radially through the inner wall of the circular ring block 21. Exhaust holes are provided on the outer wall of the exhaust pipe 5 corresponding to the positions of the push rods 22. A reset element, which is a spring 23, is sleeved on the outer surface of one end of the push rod 22. One end of the spring 23 is fixed to the outer surface of the push rod 22 opposite to the circular ring block 21, and the other end of the spring 23 is fixed to the outer surface of the circular ring block 21. Sliding holes 24 are symmetrically opened on the top end face of the exhaust pipe 5. The bottom of the hollow slide 25 extends into the interior of the exhaust pipe 5, and the sliding hole 24 is an arc-shaped hole with the arc openings of the two arc-shaped holes facing each other and the ends of the two arc-shaped holes spaced a certain distance apart. A circle can be drawn along the outer edge of the two arc-shaped holes, with the diameter of the circle being smaller than the diameter of the annular block 21. The hollow slide 25 is slidably connected to the sliding hole 24, so that the bottom of the hollow slide 25 passes through the annular block 21. A telescopic component 26 is fixedly connected to the top end face of the exhaust pipe 5. The telescopic component 26 is an electric telescopic rod, and the telescopic head end of the telescopic component 26 is fixedly connected to the top end face inside the hollow slide 25. This is used in the fermentation tank 1 to ferment pre-treated kitchen waste to prepare a carbon source. During processing, pre-treated kitchen waste is first poured into the feed hopper 7 and then into the fermentation tank 1. Simultaneously, microorganisms are added to the fermentation tank 1. Then, the stirring mechanism on the tank lid 4 is activated to mix the microorganisms and kitchen waste inside the fermentation tank 1 evenly, ensuring thorough mixing and fermentation. During fermentation, the telescopic component 26 is activated, causing the hollow sliding bucket 25 to slide downwards through the sliding hole 24. One end of the bucket abuts against the inner ends of several push rods 22 on the ring block 21, pushing it outwards to a certain position, stretching the spring 23. One end of the push rod 22 is then inserted into the corresponding exhaust hole on the exhaust pipe 5. The vent hole is blocked, thus sealing the vent pipe 5. When venting is needed, the hollow slide 25 is moved upward by the telescopic component 26. Under the reset action of the spring 23, the end of the push rod 22 located at the vent hole slides out of the vent hole to vent the gas in the fermenter 1. If some fermented material splashes into the vent hole on the vent pipe 5 during venting, the push rod 22 will push the splashed fermented material out of the vent hole when the vent hole is closed next time, cleaning the vent hole and preventing the vent hole on the vent pipe 5 from becoming blocked. This improves the venting effect and efficiency of the fermenter 1 and reduces the safety hazards caused by untimely venting of the fermenter 1.

[0040] Reference Figures 2-4As shown, the inner end face of the top rod 22 is set as an inclined surface, and a trapezoidal platform is provided at the bottom end of the hollow slide barrel 25 near the top rod 22. By combining the inclined surface of the top rod 22 and the trapezoidal platform of the hollow slide barrel 25, when the telescopic member 26 pulls the hollow slide barrel 25 downward, the trapezoidal platform can be quickly inserted between several top rods 22, and the trapezoidal platform contacts the inclined surface, facilitating the compression and pushing of the top rods 22. Multiple reinforcing rods 29 are fixedly connected to the outer surface of the telescopic member 26's telescopic head, and one side of the reinforcing rod 29 is fixedly connected to the inner wall of the hollow slide barrel 25. By setting the reinforcing rods 29, the connection area between the telescopic head of the telescopic member 26 and the hollow slide barrel 25 can be increased, making the connection more secure and stable, and less prone to damage. Multiple rollers 210 are rotatably connected to the inclined surface of the push rod 22. The rollers 210 are arranged side by side and are in rolling contact with the surface of the trapezoidal platform on the hollow slide barrel 25. By setting the rollers 210, the contact friction between the inclined surface of the push rod 22 and the outer surface of the trapezoidal platform on the hollow slide barrel 25 can be reduced, making the push rod 22 more smoothly when the hollow slide barrel 25 squeezes and pushes it, thus improving the service life of both.

[0041] Reference Figures 2-4 As shown, an inner scraper frame 27 is fixedly connected to the bottom end face of the trapezoidal platform on the hollow slide bucket 25. The outer wall of the inner scraper frame 27 at its bottom is in contact with the inner wall of the hollow slide bucket 25. By setting the inner scraper frame 27 and the outer scraper frame 28, the outer surface of the hollow slide bucket 25 is fixedly connected to the outer surface of the exhaust pipe 5. When the hollow slide bucket 25 slides down to a certain position in the inner wall of the sliding hole 24, it can drive the inner scraper frame 27 to scrape away from one end of the fermentation tank 1 in the inner wall of the exhaust pipe 5, thus pushing the inner scraper frame 27 away from the fermentation tank 1. The fermented material adhering to the inner wall of the exhaust pipe 5 is scraped off and cleaned, preventing the fermented material from accumulating and clogging the inner wall of the exhaust pipe 5 and affecting the exhaust of the exhaust pipe 5. At the same time, it will also drive the outer scraper frame 28 to slide on the outer surface of the exhaust pipe 5, scraping off and cleaning the fermented material pushed out of the exhaust hole by the top rod 22, improving the cleaning efficiency of the top rod 22, and preventing the fermented material from being stuck outside the exhaust hole when the top rod 22 retracts, which would cause blockage. This improves the exhaust effect and efficiency of the exhaust hole on the exhaust pipe 5.

[0042] Reference Figure 5 As shown, the protective part 3 includes a protective cover 33. The outer surface of the feed hopper 7 is symmetrically and fixedly connected to the port of the feed hopper 7. A round shaft 32 is rotatably connected between the two protrusions 31. The outer surface of the round shaft 32 is connected to one end of the protective cover 33. When it is not necessary to fill the feed hopper 7, the protective cover 33 can be manually rotated on the protrusion 31 through the round shaft 32 at a certain angle, and then one side of the protective cover 33 is placed on the top of the feed hopper 7 to block the feed port of the feed hopper 7, so as to prevent external debris from entering the feed hopper 7 and falling into the fermentation tank 1, which would affect the later use.

[0043] Reference Figure 5 As shown, bearings 34 are fixedly connected to the outer surface of the protrusions 31 on the round shaft 32. The outer ring of the bearing 34 is fixedly connected to the inner wall of the bearing mounting hole provided on the protrusion 31. By setting the bearings 34, the rotational wear between the round shaft 32 and the protrusions 31 is reduced, the service life of the round shaft 32 is improved, and the protective cover 33 rotates more smoothly, making it easier to open and close the protective cover 33. A handle block 35 is fixedly connected to the top end face of the protective cover 33. The longitudinal section of the handle block 35 is U-shaped. By setting the handle block 35, it is convenient to open or close the protective cover 33.

[0044] Preferably, in this embodiment, the stirring part includes a rotating shaft, the top end of which is connected to the output shaft of the stirring drive. Multiple stirring blades are connected to the rotating shaft. The stirring drive drives the rotating shaft to rotate, thereby causing the stirring blades to rotate in the fermentation tank 1 and stirring the kitchen waste in the fermentation tank 1. The stirring drive is a drive motor.

[0045] Working principle: By setting up a cleaning section 2, when using the fermentation tank 1 to ferment pre-treated kitchen waste to prepare carbon sources, the pre-treated kitchen waste is first poured into the feed hopper 7 and enters the fermentation tank 1. At the same time, microorganisms are added to the fermentation tank 1. Then, the stirring component on the tank lid 4 is activated to mix the microorganisms and kitchen waste inside the fermentation tank 1 evenly, so that the microorganisms and kitchen waste in the fermentation tank 1 can be fully mixed and fermented. During fermentation, the telescopic component 26 can be activated to drive the hollow sliding bucket 25 to slide downward in the sliding hole 24, so that one end abuts against the... The inclined surface of the push rod 22 installed on the annular block 21 is used to push the push rod 22 outward to a certain position, causing the spring 23 installed on the push rod 22 to be stretched open. One end of the push rod 22 is inserted into the corresponding exhaust hole on the exhaust pipe 5 to seal the exhaust hole and achieve the closure of the exhaust pipe 5. When exhaust is required, the telescopic component 26 works to drive the hollow slide 25 to move upward. Under the action of the spring 23, the push rod 22 is driven to return to its original position and slide out of the exhaust hole, opening the exhaust hole and exhausting the gas in the fermenter 1. If exhaust is required, some fermented material When the material splashes into the vent hole on the vent pipe 5, after venting is complete, the hollow slide barrel 25 is driven to slide downward in the slide hole 24 by the telescopic component 26. Then, when the vent hole is blocked by the push rod 22, the push rod 22 pushes out the fermented material splashed into the vent hole, thus cleaning the vent hole and preventing blockage of the vent hole on the vent pipe 5. This improves the venting effect and efficiency and reduces potential safety hazards. As the hollow slide barrel 25 slides downward in the inner wall of the slide hole 24, the inner scraper frame 27 scrapes and pushes the material towards one end of the fermentation tank 1 in the inner wall of the vent pipe 5. The outer scraper frame 28 scrapes off the fermented material adhering to the inner wall of the exhaust pipe 5, thus cleaning the inner wall of the exhaust pipe 5 and preventing the fermented material from accumulating in the inner wall of the exhaust pipe 5, causing blockage and affecting the exhaust of the exhaust pipe 5. At the same time, the outer scraper frame 28 slides upward on the outer surface of the exhaust pipe 5, removing the fermented material pushed out of the exhaust hole by the top rod 22 from the outer surface of the exhaust pipe 5, improving the cleaning efficiency of the top rod 22, and preventing the fermented material from being stuck outside the exhaust hole when the top rod 22 retracts, thus preventing blockage. This improves the exhaust effect and efficiency of the exhaust hole on the exhaust pipe 5.

[0046] When it is not necessary to fill the feed hopper 7, the protective cover 33 can be rotated on the protrusion 31 by manually holding the handle block 35 and rotating through the round shaft 32, so that one end of the protective cover 33 covers the top port of the feed hopper 7, sealing its inlet and preventing external debris, dust and other objects from entering the feed hopper 7 and falling into the fermentation tank 1, which would affect its later use.
