Description

Technical Field

[0001] This invention relates to the field of aerobic composting technology, specifically to an aerobic composting device and method for kitchen waste. Background Technology

[0002] Aerobic composting is a process in which aerobic bacteria absorb, oxidize, and decompose waste under well-ventilated and oxygen-sufficient conditions. Through their life activities, aerobic microorganisms oxidize some of the absorbed organic matter into simple inorganic substances, releasing energy needed for their growth and activities. The remaining organic matter is synthesized into new cytoplasm, enabling the microorganisms to continuously grow and reproduce, producing more organisms.

[0003] Existing aerobic composting devices for food waste can only pile the food waste together when composting it, without ventilating and mixing the inside. Current aerobic composting devices can only ventilate the surface of the food waste, making it difficult to react inside the food waste. This results in a long composting cycle and affects the treatment effect of food waste. Summary of the Invention

[0004] The purpose of this invention is to provide an aerobic composting device and method for kitchen waste to solve the problems mentioned in the background art.

[0011] Furthermore, the stirring component includes an extrusion plate, which is fixedly connected to the surface of the rotating frame, and a stirring plate is fixedly connected to the surface of the extrusion plate;

[0012] A connecting plate is provided at the end of the stirring plate away from the extrusion plate, and a scraper is fixedly connected to the end of the connecting plate away from the stirring plate.

[0013] Furthermore, the bottom of the rotating rod is rotatably connected to the top of the filter plate, and four mixing plates are provided, arranged circumferentially around the rotating frame. The end of the scraper away from the mixing plate is in contact with the inner wall of the composting rack.

[0014] Furthermore, the pushing component includes an elastic sheet, which is fixedly connected to the surface of the stirring plate. A force-bearing plate is hinged to the end of the elastic sheet away from the stirring plate. A rectangular frame is sleeved on the end of the force-bearing plate away from the elastic sheet. The end of the rectangular frame is fixedly connected to the surface of the through-hole frame. An inclined plate is rotatably connected to the inner wall of the force-bearing plate. A cleaning plate is hinged to the end of the inclined plate away from the force-bearing plate.

[0015] The surface of the cleaning plate is hinged with a spring piece, and the end of the spring piece away from the cleaning plate is fixedly connected to the surface of the force plate. The surface of the stirring plate is fixedly connected with a positioning rod.

[0016] Furthermore, the end of the movable plate away from the spring extends to the outer end of the through-hole frame, the end of the movable plate away from the spring is fixedly connected to the connecting plate, the end of the cleaning plate away from the inclined plate contacts the surface of the stirring plate, and the end of the positioning rod near the stirring plate contacts the surface of the cleaning plate.

[0017] Furthermore, the ventilation component includes a limiting ring, the top of which is fixedly connected to the bottom of the vertical rod, and an elastic rod is fixedly connected to the top of the limiting ring;

[0018] The top of the elastic rod is fixedly connected to the inner wall of the feed rack, and the bottom of the limiting ring is fixedly connected to a compression ball.

[0019] Furthermore, the surface of the limiting ring contacts the inner wall of the feeding rack, and the extrusion ball is located inside the upper part of the composting rack.

[0020] Furthermore, the water filtration component includes a conical ring, the upper surface of which is fixedly connected to the inner wall of the composting rack, a water storage ring fixedly connected to the bottom of the conical ring, the bottom of which is fixedly connected to the bottom of the inner wall of the composting rack, a one-way valve communicating with the surface of the water storage ring, a lifting plate provided inside the conical ring, a grooved frame fixedly connected to the inner wall of the water storage ring, and a spring rod fixedly connected to the bottom of the inner wall of the grooved frame.

[0021] The top of the elastic rod is fixedly connected to a lifting plate, the top of the lifting plate is fixedly connected to the top of the lifting plate, and the bottom of the synchronizing rod is fixedly connected to the top of the lifting plate.

[0022] Furthermore, the conical ring is located below the filter plate, the end of the one-way valve away from the water storage ring passes through the composting rack and extends to the outer end of the composting rack, the surface of the lifting plate is adapted to the inner wall of the water storage ring, and the surface of the lifting plate is slidably connected to the surface of the grooved frame.

[0023] Furthermore, the composting method of the aerobic composting equipment for kitchen waste includes the following steps:

[0024] S1: The mixing component mixes the kitchen waste, allowing for adequate ventilation inside the composting rack. As the mixing component rotates, the pushing component on its surface moves to clean the surface of the mixing component.

[0025] S2: When the mixing plate rotates, it can mix the kitchen waste inside the composting rack, preventing the kitchen waste from accumulating inside the composting rack and affecting the composting effect;

[0026] S3: When the mixing plate rotates, the force plate will be subjected to force and the elastic sheet will be squeezed and deformed. When the force plate moves, it pushes the cleaning plate to move on the surface of the mixing plate through the inclined plate, and the cleaning plate is used to clean the surface of the mixing plate.

[0027] S4: When the limit ring moves upward, it pushes the sealing plate to separate from the top of the feed rack through the vertical rod, so that the outside gas of the compost rack can enter the interior of the compost rack for ventilation.

[0028] S5: When the inclined frame moves downward, it pushes the lifting plate to move into the water storage ring through the synchronous rod, and squeezes the water in the water storage ring. After being squeezed, the water can be discharged through the one-way valve, so that the water in the kitchen waste can be discharged quickly.

[0029] The present invention has the following beneficial effects:

[0030] This invention involves placing kitchen waste into the composting rack via a feeding rack. A motor is then activated to rotate the mixing component, which agitates the kitchen waste, ensuring adequate ventilation within the composting rack. As the mixing component rotates, a pushing component moves, cleaning the surface of the mixing component and preventing kitchen waste from adhering to the mixing plate and affecting the mixing effect. The rotating component also pushes the ventilation component upwards, allowing it to separate from the top of the feeding rack. This facilitates the placement of kitchen waste into the composting rack and provides ventilation. A water filtration component is located at the bottom of the composting rack to separate moisture from the kitchen waste, further improving the efficiency of aerobic composting.

[0031] When the rotating rod of this invention rotates, it drives the mixing plate to rotate through the rotating frame. When the mixing plate rotates, it can stir the kitchen waste inside the composting rack, preventing the kitchen waste from accumulating inside the composting rack and affecting the composting effect. When the mixing plate stirs the kitchen waste, it can also tumble the kitchen waste, so as to avoid only ventilating the surface of the kitchen waste when ventilating it, so as to carry out the composting reaction inside the kitchen waste.

[0032] When the mixing plate of this invention rotates, the force plate is subjected to force and the elastic sheet is compressed and deformed. When the force plate moves, it pushes the cleaning plate on the surface of the mixing plate through the inclined plate. The cleaning plate cleans the surface of the mixing plate and prevents the food waste from accumulating on the surface of the mixing plate when the mixing plate is mixing. When the force plate is inclined towards the surface of the mixing plate, it will contact the surface of the sliding frame and compress the sliding frame to move on the surface of the through frame. When the sliding frame moves, it compresses the scraper through the connecting plate, so that the scraper can adhere to the inner wall of the composting rack and clean the inner wall of the composting rack, preventing food waste from adhering to the inner wall of the composting rack and affecting the composting effect.

[0033] When the mixing plate of this invention rotates, it can contact the surface of the extrusion ball, and the curvature of the extrusion ball pushes the limiting ring to move upward. When the limiting ring moves upward, it pushes the sealing plate to separate from the top of the feeding rack through the vertical rod, so that the gas outside the composting rack can enter the interior of the composting rack through the feeding rack for ventilation treatment, thereby improving the aerobic composting efficiency of kitchen waste by utilizing the gas flow.

[0034] In this invention, the moisture in kitchen waste enters the interior of the water storage ring through the filter plate for storage. When the rotating frame rotates, the extrusion plate on its surface will press the inclined frame downward. When the inclined frame moves downward, it pushes the lifting plate to move into the interior of the water storage ring through the synchronous rod, and squeezes the moisture in the water storage ring. After being squeezed, the moisture can be discharged through the one-way valve, so that the moisture in the kitchen waste can be discharged quickly. The lifting plate can be pushed upward by the elasticity of the spring rod to reset, so that the lifting plate can repeatedly squeeze the moisture in the water storage ring.

[0035] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

The stirring component 4 stirs the kitchen waste, allowing the kitchen waste inside the composting rack 1 to be fully ventilated. When the stirring component 4 rotates, the pushing component 5 on its surface will start to move, utilizing the pushing component... 5. Clean the surface of the mixing component 4 to prevent kitchen waste from adhering to the surface of the mixing plate 13 and affecting the mixing effect. When the mixing component 4 rotates, it pushes the ventilation component 6 upward, so that the ventilation component 6 can be separated from the top of the feeding rack 2, so that the kitchen waste can be placed into the composting rack 1 through the feeding rack 2, and the interior of the composting rack 1 can be ventilated through the feeding rack 2. A water filter component 7 is set at the bottom of the interior of the composting rack 1.

[0056] The bottom of the rotating rod 10 is rotatably connected to the top of the filter plate 53. Four stirring plates 13 are provided, arranged circumferentially around the rotating frame 11. When the rotating rod 10 rotates, it drives the stirring plates 13 to rotate through the rotating frame 11. When the stirring plates 13 rotate, they can stir the kitchen waste inside the composting rack 1, preventing the kitchen waste from accumulating inside the composting rack 1 and affecting the composting effect. When the stirring plates 13 stir the kitchen waste, they can tumble the kitchen waste, preventing ventilation from only ventilating the surface of the kitchen waste, so that the internal composting reaction of the kitchen waste can take place. The end of the scraper 15 away from the stirring plate 13 contacts the inner wall of the composting rack 1.

[0057] The feeding component 5 includes an elastic sheet 20, which is fixedly connected to the surface of the mixing plate 13. A force plate 24 is hinged to the end of the elastic sheet 20 away from the mixing plate 13. A rectangular frame 29 is sleeved on the end of the force plate 24 away from the elastic sheet 20. The end of the rectangular frame 29 is fixedly connected to the surface of the through-hole frame 26. An inclined plate 21 is rotatably connected to the inner wall of the force plate 24.

[0059] The end of the movable plate 27 away from the spring 31 extends to the outer end of the through-hole bracket 26. The end of the movable plate 27 away from the spring 31 is fixedly connected to the connecting plate 14. When the stirring plate 13 rotates, the force plate 24 will be subjected to force and will compress the elastic sheet 20 to produce deformation. When the force plate 24 moves, it pushes the cleaning plate 22 to move on the surface of the stirring plate 13 through the inclined plate 21. The cleaning plate 22 is used to clean the surface of the stirring plate 13 to prevent the food waste from accumulating on the surface of the stirring plate 13 when the stirring plate 13 is stirring. The force plate 24 moves towards... When the surface of the mixing plate 13 is tilted, it will contact the surface of the sliding frame 30 and squeeze the sliding frame 30 to move on the surface of the through-hole frame 26. When the sliding frame 30 moves, it squeezes the scraper 15 through the connecting plate 28, so that the scraper 15 can adhere to the inner wall of the composting rack 1 to clean the inner wall of the composting rack 1, so as to avoid the food waste from adhering to the inner wall of the composting rack 1 and affecting the composting effect. The end of the cleaning plate 22 away from the inclined plate 21 contacts the surface of the mixing plate 13, and the end of the positioning rod 25 close to the mixing plate 13 contacts the surface of the cleaning plate 22.

[0060] The ventilation component 6 includes a limiting ring 42, the top of which is fixedly connected to the bottom of the vertical rod 41, and an elastic rod 44 is fixedly connected to the top of the limiting ring 42.

[0062] The surface of the limiting ring 42 contacts the inner wall of the feeding rack 2. When the stirring plate 13 of the present invention rotates, it can contact the surface of the extrusion ball 43, and the curvature of the extrusion ball 43 pushes the limiting ring 42 to move upward. When the limiting ring 42 moves upward, it pushes the sealing plate 40 to separate from the top of the feeding rack 2 through the vertical rod 41, so that the gas outside the composting rack 1 can enter the interior of the composting rack 1 through the feeding rack 2 for ventilation treatment.

[0064] The top of the elastic rod 59 is fixedly connected to the lifting plate 58, the top of the lifting plate 58 is fixedly connected to the top of the lifting plate 57, and the bottom of the synchronizing rod 51 is fixedly connected to the top of the lifting plate 57.

[0065] The conical ring 54 is located below the filter plate 53. The end of the one-way valve 56 away from the water storage ring 55 passes through the composting rack 1 and extends to the outer end of the composting rack 1. The water in the kitchen waste of the present invention enters the interior of the water storage ring 55 through the filter plate 53 for storage. When the rotating rack 11 rotates, the extrusion plate 12 on the surface will extrude the inclined rack 52 downward. When the inclined rack 52 moves downward, it pushes the lifting plate 57 to move into the interior of the water storage ring 55 through the synchronizing rod 51 and extrudes the water in the water storage ring 55. After the water is extruded, it can be discharged through the one-way valve 56, so that the water in the kitchen waste can be discharged quickly. The lifting plate 57 can be pushed upward by the elasticity of the elastic rod 59 to reset, so that the lifting plate 57 can reciprocate to extrude the water in the water storage ring 55. The surface of the lifting plate 57 is adapted to the inner wall of the water storage ring 55, and the surface of the lifting plate 57 is slidably connected to the surface of the groove rack 60.

[0066] A composting method for kitchen waste using an aerobic composting device includes the following steps:

[0067] S1: The kitchen waste is stirred by the stirring component 4, so that the kitchen waste inside the composting rack 1 can be fully ventilated. When the stirring component 4 rotates, the pushing component 5 on the surface will start to move, and the pushing component 5 is used to clean the surface of the stirring component 4.

[0068] S2: When the mixing plate 13 rotates, it can mix the kitchen waste inside the composting rack 1, so as to prevent the kitchen waste from accumulating inside the composting rack 1 and affecting the composting effect.

[0069] S3: When the stirring plate 13 rotates, the force plate 24 will be subjected to force and squeeze the elastic sheet 20 to produce deformation. When the force plate 24 moves, it pushes the cleaning plate 22 to move on the surface of the stirring plate 13 through the inclined plate 21, and uses the cleaning plate 22 to clean the surface of the stirring plate 13.

[0070] S4: When the limiting ring 42 moves upward, it pushes the sealing plate 40 to separate from the top of the feeding rack 2 through the vertical rod 41, so that the outside gas of the composting rack 1 can enter the interior of the composting rack 1 through the feeding rack 2 for ventilation.

[0071] S5: When the inclined frame 52 moves downward, it pushes the lifting plate 57 to move into the water storage ring 55 through the synchronous rod 51, and squeezes the water in the water storage ring 55 so that the water can be discharged through the one-way valve 56 after being squeezed, so that the water in the kitchen waste can be discharged quickly.

[0072] In use, after placing kitchen waste into the composting rack 1 through the feeding rack 2, the motor 3 is started to drive the mixing component 4 to rotate. The mixing component 4 mixes the kitchen waste, allowing for sufficient ventilation inside the composting rack 1. As the mixing component 4 rotates, the pushing component 5 on its surface moves, cleaning the surface of the mixing component 4 to prevent kitchen waste from adhering to the mixing plate 13 and affecting the mixing effect. The rotating mixing component 4 pushes the ventilation component 6 upwards, allowing it to separate from the top of the feeding rack 2. This allows the kitchen waste to be placed into the composting rack 1 through the feeding rack 2, and also provides ventilation inside the composting rack 1. A water filter component 7 is installed at the bottom of the composting rack 1. This component separates the water from the food waste, improving the efficiency of aerobic composting. When the rotating rod 10 rotates, it drives the mixing plate 13 to rotate via the rotating frame 11. The mixing plate 13 stirs the food waste inside the composting rack 1, preventing it from accumulating and affecting the composting effect. The mixing plate 13 also tumbles the food waste, preventing ventilation from only affecting the surface and allowing for composting within the waste. When the mixing plate 13 rotates, the force plate 24 is stressed and compresses the elastic sheet 20. As the load-bearing plate 24 moves, it pushes the cleaning plate 22 across the surface of the mixing plate 13 via the inclined plate 21. The cleaning plate 22 cleans the surface of the mixing plate 13, preventing food waste from accumulating on its surface during mixing. When the load-bearing plate 24 tilts towards the surface of the mixing plate 13, it contacts the surface of the sliding frame 30 and compresses the sliding frame 30 as it moves across the surface of the through-hole frame 26. As the sliding frame 30 moves, it compresses the scraper 15 via the connecting plate 28, allowing the scraper 15 to adhere to the inner wall of the composting rack 1 and clean it, preventing food waste from adhering to the inner wall and affecting the composting effect. When the mixing plate 13 rotates, it can contact the surface of the extrusion ball 43. Furthermore, the curvature of the compression ball 43 pushes the limiting ring 42 upward. When the limiting ring 42 moves upward, it pushes the sealing plate 40 to separate from the top of the feeding rack 2 via the vertical rod 41, so that external gas can enter the composting rack 1 through the feeding rack 2 for aeration. The flow of gas improves the aerobic composting efficiency of kitchen waste. The moisture in the kitchen waste enters the water storage ring 55 through the filter plate 53 for storage. When the rotating frame 11 rotates, the compression plate 12 on its surface will squeeze the inclined frame 52 downward. When the inclined frame 52 moves downward, it pushes the lifting plate 57 to move into the water storage ring 55 via the synchronous rod 51, and squeezes the moisture in the water storage ring 55. After being squeezed, the moisture can be discharged through the one-way valve 56.This allows for the rapid drainage of moisture from food waste. The lifting plate 57 can be pushed upwards by the elasticity of the spring rod 59 to reset, enabling the lifting plate 57 to repeatedly squeeze the water in the water storage ring 55.
