Description

Technical Field

[0001] This utility model relates to the field of biological waste composting technology, specifically a closed-loop energy control device for biological waste composting. Background Technology

[0002] The fully closed-loop energy control device for biological waste composting is an environmentally friendly equipment that efficiently converts organic waste into fertilizer and recovers energy in a closed environment by automatically regulating temperature, humidity and ventilation.

[0003] In existing technologies, common biological waste composting devices typically employ a single-shaft, centrally located stirring structure, supplemented by bottom aeration for oxygen supply. However, this structural feature limits the stirring range, easily creating dead zones at the edges and bottom corners of the reaction chamber. This prevents the material in these areas from fully contacting fresh air. Furthermore, single bottom ventilation is prone to short-circuiting or uneven distribution when passing through the viscous and dense compost layer, failing to provide uniform and sufficient oxygen to the entire compost, especially in the aforementioned dead zones. These deficiencies collectively lead to localized oxygen deficiency in the compost material, triggering anaerobic fermentation and producing malodorous substances such as hydrogen sulfide and ammonia. This not only reduces composting efficiency and product quality but also causes serious secondary environmental pollution. Utility Model Content

[0004] The purpose of this invention is to provide a closed-loop energy control device for composting biological waste, which solves the problem of anaerobic odor in some areas caused by uneven fermentation.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a closed-loop energy control device for composting biological waste, comprising a reaction structure. The reaction structure has an inner wall of a reaction chamber. A first motor is located above the inner wall of the reaction chamber. The first motor is connected to a first drive shaft extending into the reaction chamber. A first drive blade is provided on the first drive shaft. A first gear is fixedly provided at the bottom of the first drive shaft. A second gear is meshed with each side of the first gear. A second drive shaft is connected to the bottom of each second gear. Two fixed connecting plates are provided on the inner wall of the reaction chamber. The second drive shaft passes through the fixed connecting plates, and a second drive blade is arranged in a circumferential array on the shaft section between the two fixed connecting plates.

[0006] Furthermore, a temperature-controlled water pipe is spirally wound around the outer wall of the inner wall of the reaction chamber, and both the inlet and outlet ends of the temperature-controlled water pipe extend to the outside of the reaction chamber.

[0007] Furthermore, the bottom of the inner wall of the reaction chamber is a conical structure. An auxiliary shaftless spiral is provided at the bottom opening of the conical structure. The shaftless spiral is housed in a spiral fixing cylinder. One end of the spiral is connected to a third drive shaft, which is connected to a second motor. A discharge pipe is connected to the side wall of the spiral fixing cylinder. A water pump is connected to the outer part of the temperature-controlled water pipe, and a water tank is connected to the other side of the temperature-controlled water pipe.

[0008] Furthermore, it also includes a blower, the blower's outlet duct extending into the interior of the reaction chamber's inner wall, the blower's inlet duct connected to a return branch pipe, the return branch pipe being connected to the exhaust pipe at the top of the reaction chamber, and another duct connected above the blower's duct, with a regulating valve in the middle of the duct, the regulating valve controlling the exhaust gas portion above to enter the blower-controlled inlet duct.

[0009] Furthermore, an exhaust structure is connected to one side of the reaction structure. The exhaust structure is equipped with an exhaust pipe, which is connected in sequence to a filter pipe and a filter box. The filter box has multiple parallel filter layers inside, and an exhaust pipe is provided at its tail end. An exhaust support column is provided at the bottom of the exhaust structure.

[0010] Furthermore, the outer side of the spirally coiled temperature-controlled water pipe is covered with an insulating outer wall, and the top of the reaction structure is also provided with a feed pipe, and the bottom is provided with a support column.

[0011] This utility model has the following beneficial effects: (1) This utility model uses a first motor set above the inner wall of the reaction chamber to drive the first drive shaft and the first drive fan blade to perform central stirring. At the same time, the first gear at the bottom of the shaft meshes with the second gears on both sides to synchronously drive the two second drive shafts and the second drive fan blades on them to rotate. The second drive shaft is stably supported by a fixed connecting plate. This structure constitutes a collaborative stirring mode with one shaft driving multiple shafts, which expands the mechanical stirring range, eliminates the stirring dead angles at the edge and bottom of the reaction chamber, and makes the material fully and evenly contact oxygen, thereby avoiding anaerobic fermentation and odor caused by local hypoxia.

[0012] (2) This utility model uses a spiral coiled temperature control water pipe on the outer side of the inner wall of the reaction chamber and connects it to the water tank through a water pump to form a circulation loop. At the same time, the outer side of the coil is covered with an insulation outer wall. This structure realizes active and precise temperature control of the composting reaction process. It can not only remove excess heat in time to prevent microbial inactivation, but also supplement heat at low temperatures to maintain efficient fermentation. It also uses the insulation layer to minimize heat loss, significantly reducing the system's operating energy consumption and ensuring that the composting process is always in the optimal temperature range.

[0013] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0017] Please see Figures 1-4As shown, this utility model is a closed-loop energy control device for composting biological waste, including a reaction structure 1. The reaction structure 1 is provided with an inner wall 101 of the reaction chamber. A first motor 102 is provided above the inner wall 101 of the reaction chamber. The first motor 102 is connected to a first drive shaft 103 that extends into the interior of the reaction chamber. A first drive fan blade 104 is provided on the first drive shaft 103. A first gear 105 is fixedly provided at the bottom of the first drive shaft 103. A second gear 106 is meshed with each side of the first gear 105. A second drive shaft 107 is connected to the bottom of each second gear 106. Two fixed connecting plates 109 are provided on the inner wall 101 of the reaction chamber. The second drive shaft 107 passes through the fixed connecting plate 109, and the second drive fan blades 108 are arranged in a circular array on the shaft section between the two fixed connecting plates 109. A temperature-controlled water pipe 110 is spirally wound around the outer wall of the inner wall 101 of the reaction chamber, and the inlet and outlet of the temperature-controlled water pipe 110 extend to the outside of the reaction chamber. The outer side of the spirally coiled temperature-controlled water pipe 110 is covered with an insulating outer wall 112; The reaction structure 1 is also provided with a feed pipe 111 at the top and a support column 113 at the bottom; Please refer to Figure 1 As shown, biological waste first enters the space formed by the inner wall 101 of the reaction chamber through the feed pipe 111. Then, the first motor 102 starts and drives the first drive shaft 103 and the first drive fan blades 104 set on it to rotate, thereby stirring the central area of ​​the material. At the same time, the first gear 105 at the bottom of the first drive shaft 103 drives the second gears 106 meshing with it on both sides to rotate, thereby driving the two second drive shafts 107 to rotate synchronously. While the second drive shafts 107 are stably supported by passing through the fixed connecting plate 109, they drive the second drive fan blades 108 in a circular array on the shaft section between them to stir the material in the edge area of ​​the reaction chamber. During this process, the temperature-controlled water pipe 110 spirally coiled around the outside of the inner wall 101 of the reaction chamber heats or cools the reaction chamber through the medium circulating inside it, while the heat-insulating outer wall 112 covering it effectively reduces heat loss. The entire reaction structure 1 is stably supported by the support column 113 at the bottom. Please see Figure 2 , Figure 4 As shown, the bottom of the inner wall 101 of the reaction chamber is a conical structure, and an auxiliary structure 3 with a shaftless spiral 301 is provided at the bottom opening of the conical structure. The shaftless spiral 301 is housed in the spiral fixing cylinder 302, and one end of it is connected to the third drive shaft 305, which is connected to the second motor 304. A discharge pipe 303 is connected to the side wall of the spiral fixed cylinder 302; The temperature-controlled water pipe 110 extends to the outer part and is connected to a water pump 306; the other side of the temperature-controlled water pipe 110 is connected to a water tank 307. It also includes a blower 308, whose outlet duct extends into the interior of the reaction chamber inner wall 101; The blower 308 has a return branch pipe connected to its air inlet pipe, which is connected to the exhaust pipe 21 at the top of the reaction chamber. Above the pipe connected to the blower 308 is another pipe, and in the middle of the pipe is a regulating valve 309. The regulating valve 309 controls the exhaust gas from the upper part to enter the intake pipe controlled by the blower 308. Among them, water pump 306 is a water pumping structure, please refer to the patent number "CN103410742A Compound Water Pump" for details; Once composting is complete, the second motor 304 starts, driving the third drive shaft 305 to rotate the shaftless screw 301 inside the screw fixed cylinder 302, pushing the finished fertilizer collected at the bottom of the cone upwards and finally discharging it through the discharge pipe 303, achieving closed, continuous, and unblocked discharge. At the same time, the water pump 306 drives the medium to circulate between the water tank 307 and the spirally wound temperature-controlled water pipe 110, thereby actively heating or cooling the reaction chamber to maintain the optimal fermentation temperature. The blower 308 continuously delivers air into the reaction chamber, while the regulating valve 309 located on its air inlet pipe precisely controls the amount of exhaust gas returning from the exhaust pipe 21, mixing it with fresh air before it re-enters the reaction chamber. Please see Figure 2 , Figure 3 As shown, one side of the reaction structure 1 is connected to the exhaust structure 2. The exhaust structure 2 is provided with an exhaust pipe 21. The exhaust pipe 21 is connected in sequence to the filter pipe 22 and the filter box 23. The filter box 23 is provided with multiple parallel filter layers 24 inside, and its tail is provided with an exhaust pipe 25. The bottom of the exhaust structure 2 is provided with an exhaust support column 26; The high-temperature, humid waste gas generated by the composting reaction, containing odorous substances and suspended particles, is first discharged from the exhaust pipe 21 at the top of the reaction chamber. Then, the waste gas passes through the filter pipe 22 and enters the filter box 23. Inside the filter box 23, the waste gas is forced to pass through multiple parallel filter layers 24. These layers remove harmful components and particulate matter from the waste gas step by step through adsorption, absorption, or biodegradation. Finally, the thoroughly purified gas is discharged into the atmosphere from the exhaust pipe 25 at the tail of the filter box 23. The entire exhaust structure 2 is stably supported by the exhaust support column 26 at its bottom.

[0018] In operation, the operator first feeds the biological waste into the device through the feed pipe 111, then starts the system. The first motor 102 drives the first drive shaft 103 and its first drive fan blade 104 to rotate. At the same time, the first gear 105 at the bottom of the shaft drives the second gears 106 on both sides, causing the two second drive shafts 107 to rotate synchronously in opposite directions under the support of the fixed connecting plate 109. This drives the second drive fan blades 108 to stir the material throughout the entire area, completely eliminating dead zones. Meanwhile, the blower 308 pumps air into the reaction chamber, and the regulating valve 309 on its air intake pipe regulates the amount of exhaust gas returning from the exhaust pipe 21, achieving energy saving and humidity control. The heat generated by composting is managed by the temperature-controlled water pipe 110 spirally wound around the inner wall 101 of the reaction chamber. The water pump 306 drives the fluid to circulate from the water tank 307, and the outer heat-insulating wall 112 reduces heat loss. The fermentation exhaust gas enters the filter box 23 through the filter pipe 22 and passes through the internal multi-layer filter layer 24. After purification, the exhaust is discharged through the exhaust pipe 25. After composting is completed, the second motor 304 drives the third drive shaft 305 to drive the shaftless screw 301 to rotate inside the screw fixed cylinder 302, pushing the finished fertilizer out from the bottom of the conical bin through the discharge pipe 303. The entire device is stably supported by the support column 113 and the exhaust support column 26.
