Description

Technical Field

[0001] This utility model specifically relates to a fermentation device for garden waste, belonging to the field of waste fermentation technology. Background Technology

[0002] Garden waste mainly includes fallen leaves and pruned branches. With the continuous expansion of urban green areas, its output is increasing day by day. Static composting and fermentation of garden waste is a common and economical way of resource utilization. Through the decomposition of microorganisms, garden waste can be transformed into humus-rich organic fertilizer, which not only reduces the amount of waste, but also replenishes soil fertility and promotes plant growth, which is in line with the concept of circular economy and green development.

[0003] However, during the static stacking of traditional garden waste, the waste is in a relatively closed state, making it difficult for external air to effectively penetrate into the pile. This poor air circulation directly limits the activity of aerobic microorganisms. Aerobic microorganisms need sufficient oxygen to participate in respiration when decomposing organic matter. Insufficient oxygen supply will significantly reduce their metabolic rate, leading to a slow fermentation process. Furthermore, when oxygen is scarce inside the pile, the metabolic pathways of microorganisms change, making them prone to anaerobic fermentation, releasing irritating and foul-smelling gases such as hydrogen sulfide and ammonia, which pollute the surrounding environment.

[0004] To address the above problems, this application proposes a fermentation device for garden waste. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a garden waste fermentation device. This device spreads crushed garden waste on the ground, with concrete walls on both sides effectively preventing overflow. Leachate is discharged through a ground trough, a guide trough, and an outlet pipe, avoiding interference with fermentation. Simultaneously, an air intake fan draws air into the compost pile to supply oxygen to aerobic microorganisms, accelerating the decomposition of organic matter. This breaks through the ventilation bottleneck of traditional static composting and integrates ventilation and leachate collection. The steel cover design facilitates the passage of operating vehicles, thus solving the problems mentioned in the background art.

[0006] A garden waste fermentation device includes: a composting mechanism comprising multiple ground troughs for collecting leachate from waste, each ground trough having a guide channel on one side and a set of ventilation pipes in each trough, the ventilation pipes having multiple sets of air outlets on their surface, a steel cover plate installed above the ground troughs, the steel cover plate having multiple sets of through holes on its surface, and a set of concrete walls on both sides above the ground, each concrete wall having an air intake fan on one side, the air intake fan blowing air into the waste piled on the ground through the air outlets to provide oxygen for microorganisms to accelerate the decomposition of organic matter; and a humidification mechanism comprising a fixed frame installed on the concrete wall, a threaded rod installed inside the fixed frame, a linkage rod threadedly connected to the top of the threaded rod and capable of sliding along the inner side of the fixed frame, and a spray head with an adjustable spray angle installed above the linkage rod.

[0007] As a preferred embodiment, an air duct groove is provided on one side of the ground, and an air guide pipe is provided inside the air duct groove. A duct groove cover plate is installed above the air duct groove.

[0008] In a preferred embodiment, one end of the multiple sets of ventilation pipes is connected to a common air guide pipe, and the air intake fan is connected to the air guide pipe through a transmission pipe.

[0009] In a preferred embodiment, the guide channel is connected to the interior of the ground channel, and an outlet pipe is installed on one side of the guide channel.

[0010] In a preferred embodiment, a No. 1 motor is installed on one side of the fixed frame, and the output shaft of the No. 1 motor is connected to the threaded rod.

[0011] In a preferred embodiment, a rotating groove is provided above the linkage rod, and the nozzle is located in the rotating groove. A second motor is installed on one side of the linkage rod, and the output shaft of the second motor is connected to one side of the nozzle. The other side of the nozzle is rotatably connected to the linkage rod through a rotating shaft.

[0012] In a preferred embodiment, a controller is installed on the lower side of one side of the fixed frame, and the controller is electrically connected to motor No. 1 and motor No. 2.

[0013] Beneficial effects:

[0014] 1. By designing a composting mechanism, crushed garden waste is evenly spread on the ground. Concrete walls are set on both sides of the ground to effectively block the waste and prevent it from sliding to the designated location. The leachate seeping from the waste flows into the ground trough and is discharged in an orderly manner to the designated storage point through the diversion channel and outlet pipe, avoiding the interference of liquid accumulation on the fermentation environment. During the stacking process, the air intake fan draws in outside air, which passes through the air outlet on the surface of the air pipe and then through the through holes on the surface of the steel cover plate into the pile, allowing oxygen to permeate into the compost waste. This design breaks through the air circulation bottleneck of traditional static composting, provides sufficient oxygen source for aerobic microorganisms, significantly accelerates the decomposition process of organic matter, and can collect leachate to the diversion channel while providing comprehensive ventilation. The covering design of the steel cover plate also facilitates the passage of operating vehicles.

[0015] 2. By designing a humidification mechanism, the linkage rod can slide laterally along the inner side of the fixed frame under the rotation of the threaded screw, thereby realizing flexible adjustment of the spray position of the nozzles to cover different areas of the waste pile. At the same time, the second motor drives the nozzles to tilt and rotate, thereby adjusting the spray angle. When the waste is relatively dry, the nozzles are aimed at the dry areas to spray water and humidify, avoiding localized dryness that may affect microbial activity and ensuring a stable and efficient fermentation process. In dry weather, the first and second motors can be started at regular intervals, and the spray position can be continuously adjusted during the spraying process to achieve scanning spraying and cover the pile area.

[0027] Please see Figures 1-5 As shown, a No. 1 motor 23 is installed on one side of the fixed frame 21, and the output shaft of the No. 1 motor 23 is connected to the threaded rod 22.

[0028] Please see Figure 1 and Figure 4 As shown, a rotating groove 27 is provided above the linkage rod 24, and the nozzle 25 is located in the rotating groove 27.

[0030] In practical use, the working principle of this utility model is as follows:

[0031] When the garden waste fermentation device is working, the crushed garden waste is first piled on the ground. Concrete walls 11 are set on both sides of the ground to effectively block the waste and prevent it from sliding to the designated location. The liquid in the waste flows into the ground trough 16 through the through hole 14, and then flows into the guide trough 12 through the ground trough 16. It can then be discharged to the storage point through the outlet pipe 111, realizing liquid separation. During the stacking process, the air intake fan 15 can draw in the outside air into the air guide pipe 110, and then the air guide pipe 110 distributes it to each ventilation pipe 18. The air is blown into the waste pile through the through hole 14 through the air outlet 19 on the surface of the ventilation pipe 18, providing sufficient oxygen for the microorganisms to decompose organic matter and accelerating the fermentation process. In addition, the design of the steel cover plate 13 covering the ground trough 16 allows for ventilation while facilitating the passage of operating vehicles.

[0032] When staff detect insufficient humidity in the waste using detection equipment such as a humidity detector, they activate motor 23 via controller 28 to rotate the threaded screw, causing linkage rod 24 to slide laterally along the inner side of fixed frame 21, adjusting the spray position of nozzle 25. Simultaneously, motor 26 rotates nozzle 25, adjusting its pitch angle to align it with the dry area. An external water inlet pipe is then connected to nozzle 25, allowing water to be sprayed from the nozzles to humidify the waste in the dry area. In relatively dry weather, controller 28 can control motors 23 and 26 to start at set times and continuously adjust the spray position during spraying, achieving scanning spraying to cover the stacked area and ensure a stable and efficient fermentation process.
