Description

Technical Field

[0001] The utility model relates to the technical field of garden waste treatment, in particular to a device for continuously composting garden waste without turning the pile. Background Art

[0002] Garden waste, primarily composed of biomass containing lignocellulosic materials, is an excellent compost material. Composting garden waste to create compost products and fertilize the soil is an effective means of treating and reusing garden waste as a resource. Due to the varying sources of garden waste, from large-scale enterprises to small-scale households, the total amount of garden waste varies. Furthermore, simply piling garden waste does not effectively form good compost. Therefore, composting equipment is particularly important for the composting of garden waste resources.

[0003] Currently, devices for composting have been published, such as a full-process, modular, multifunctional composting device and its operating method (CN202311680603.6), a sludge fermentation device for sludge composting (CN202311590539.2), an aerobic composting bin (CN202311270509.3), a landscaping organic waste composting device (CN202322618455.7), and a double-bin composting bin (CN202330465126.6). Composting bins have made significant progress and improvements in terms of their functionality, but some problems still exist, including:

[0004] 1. Complex compost bins introduce mechanical components and require a power system, which increases costs and is not easy to promote on a large scale in courtyard gardens;

[0005] 2. Composting devices are mainly box-type, and the mainstream compost bin products currently on the market are also like this. The compost bins composed of different panels cannot withstand the pressure after the compost is compacted, resulting in the compost bins expanding and cracking, which leads to the termination of composting.

[0006] 3. Most compost bins use batch fermentation mode and cannot achieve continuous operation;

[0007] 4. The composting box is large, and turning the compost consumes a lot of manpower and is not easy to operate. Utility Model Content

[0040] As follows, embodiments are further described with reference to the accompanying drawings.

[0041] like Figures 1 to 7 As shown, as a preferred embodiment 1, a device for continuous composting of garden waste without turning the pile includes a wastewater recovery tray 7, wherein a plurality of compost bucket modules 1 are stacked within the wastewater recovery tray 7. The compost bucket modules 1 are sequentially connected in a vertical direction via a socket connection mechanism 4, and the compost bucket modules 1 are interconnected. Each compost bucket module 1 includes a hollow internal skeleton 2 and an external baffle 3 that is detachably connected to the external portion of the internal skeleton 2. The top of the top compost bucket module 1 is detachably provided with a rainproof cover 5. Depending on the specific composting situation, the compost bucket modules 1 can be appropriately increased or decreased to adjust the volume or capacity of the pile. Even during the composting process, modules can be added as needed to continuously add materials for composting.

[0042] As a preferred embodiment 3, the internal skeleton 2 includes an upper fixing ring 201 and a lower fixing ring 202 of the same size. The upper fixing ring 201 is coaxially arranged directly above the lower fixing ring 202, and a plurality of support columns 203 are provided between the upper fixing ring 201 and the lower fixing ring 202. The upper fixing ring 201 is supported and fixed with the lower fixing ring 202 via the support columns 203. The hollow structure is ensured to facilitate unloading after the external baffle 3 is removed.

[0043] The support columns 203 are arranged at equal intervals around the axis, and the circular ring formed by the support columns 203 is concentric and coaxial with the lower fixing ring 202. The support columns 203 are all arranged vertically, and the diameter of the support columns 203 is smaller than the width of the lower fixing ring 202. The outer side of the support columns 203 cooperates with the upper fixing ring 201 and the lower fixing ring 202 to form a baffle groove 204. The external baffle 3 is embedded in the baffle groove 204 and cooperates with the upper fixing ring 201 and the lower fixing ring 202 to form a blocking structure. This ensures the installation and removal of the external baffle 3 and the blocking effect during fermentation.

[0044] As a preferred embodiment 4, the external baffle 3 includes a flexible baffle 301, which is embedded in the baffle groove 204 on the outer side of the support column 203 to form an annular structure, and the two ends of the flexible baffle 301 are locked and closed by a locking mechanism 302.

[0045] The locking mechanism 302 can use either a magnetic lock or Velcro.

[0046] As a preferred embodiment 5, the sleeve connection mechanism 4 is a hollow structure, and a horizontally arranged ventilation adjustment tube 8 is detachably embedded in the hollow structure of the sleeve connection mechanism 4. The ventilation volume is adjusted according to the needs of the composting. The more tubes inserted, the greater the ventilation volume, while the lower the number, the less ventilation can be achieved. This allows for flexible adjustment of the ventilation of the compost pile according to the composting conditions. The tubes are inserted as needed, and are only inserted when ventilation is required and bottom discharge is required.

[0047] As a preferred embodiment 6, the sleeve connection mechanism 4 includes an outer frame 401 and an inner frame 402. Both the outer frame 401 and the inner frame 402 are annular structures. The outer frame 401 is coaxially fixed to the bottom of the lower fixing ring 202, and the inner frame 402 is coaxially fixed to the top of the upper fixing ring 201. The outer frame 401 of adjacent compost bucket modules 1 is sleeved on the outside of the inner frame 402, and the bottom of the outer frame 401 just supports the top of the upper fixing ring 201 of the lower compost bucket module 1, and the top of the inner frame 402 just connects with the bottom of the lower fixing ring 202 of the upper compost bucket module 1. This ensures the stability of adjacent compost bucket modules 1 after installation, facilitates installation, and facilitates real-time adjustment according to composting conditions.

[0048] Both the inner frame 402 and the outer frame 401 are provided with equally spaced hollow holes 403, with the hollow holes 403 of the inner frame 402 corresponding to the hollow holes 403 of the outer frame 401. During installation, the corresponding hollow holes 403 are aligned and connected. The ventilation regulating tube 8 is inserted horizontally through the hollow holes 403 and extends through the sleeve connecting mechanism 4. This facilitates pipe insertion, not only to replenish gas for fermentation, but also to support the fiber fermentation mass above. By securing the upper fiber fermentation mass with an appropriate number of ventilation regulating tubes 8, the upper fiber fermentation mass can be isolated and supported. The flexible baffle 301 of the current bucket can be opened to release and remove the compost material in that layer. The flexible baffle 301 is then reinstalled, the ventilation regulating tube 8 is withdrawn, and the compost material falls, ultimately forming a continuous composting process with compost material entering from above and exiting from below, eliminating the need for turning the pile. Compost can also be obtained in different layers according to the composting conditions.

[0049] The ventilation regulating tube 8 is open at one end and tapered at the other, with a plurality of ventilation holes 801 evenly distributed on the sidewall. This facilitates insertion of the ventilation regulating tube 8. The ventilation holes 801 are used to introduce external air to control the fermentation state. The tube body itself can serve as a partition to separate the materials on the upper and lower sides of the hollow hole 403.

[0050] As a preferred embodiment 7, the wastewater recovery tray 7 includes a bottom plate 701, and a vertically arranged water baffle 702 is coaxially and concentrically provided on the periphery of the bottom plate 701. The water baffle 702 is provided with a drainage hole 703 that can be blocked. The inner frame 402 is provided in the middle position of the bottom plate 701, and the outer frame 401 of the compost barrel module 1 at the bottom forms a socket-limiting fit. The fermentation wastewater generated during the composting process is collected in the bottom wastewater recovery tray 7, and the wastewater is recycled. Because the inner frame 402 is provided, the bottom of the fermentation system is connected to the wastewater recovery tray 7, and the wastewater is returned to the composting system to supplement the nitrogen source and microbial resources of the compost body. It can also be applied to the soil as fertilizer. If there is no need to recover the fermentation wastewater, it can be omitted.

[0051] As a preferred embodiment 8, the top of the compost bucket module 1 is removably provided with a rain cover 5. A recess 501 is provided in the center of the bottom of the rain cover 5, and the inner frame 402 of the top compost bucket module 1 is completely recessed within the recess 501. The presence of the rain cover 5 allows the composting process to be conducted outdoors in a garden, eliminating the need for separate rainproof structures or shelters. The presence of the rain cover 5 also reduces the volatilization and diffusion of odors during the composting process, protecting the environment.

[0052] The working principle of this utility model:

[0053] 1. The utility model adopts a cylindrical design, which can better bear the pressure of the pile compared to the rectangular box type, and solves the problem that the rectangular box is prone to cracking due to the compaction of the pile;

[0054] 2. The present invention adopts a small compost bucket module 1 combined with a sleeve connection mechanism 4, which can adjust the height and capacity according to the composting needs and is also convenient for disassembly of the compost bucket. At the same time, the external baffle 3 of the compost bucket module 1 is easy to disassemble. After disassembly, the compost can be released through the hollow structure of the internal skeleton 2 exposed after disassembly, which is labor-saving and easy to operate, and solves the problem of high labor and physical strength consumption in compost turning;

[0055] 3. The utility model realizes continuous composting operation without turning over, with continuous feeding from the upper part and continuous discharging from the bottom. By inserting an appropriate amount of ventilation regulating tube 8, the fiber fermentation mass on the upper layer is separated from the fiber fermentation mass on the lower layer, thereby ensuring that the fermentation mass on the upper layer continues to ferment while the fermentation mass on the lower layer is taken out, which is convenient for operation and saves manpower.

[0056] 4. The utility model can adjust the ventilation degree of the pile body according to the required composting conditions by using the ventilation regulating pipe 8, thereby adjusting the compost fermentation process;

[0057] 5. The present invention also designs a wastewater recovery tray 7, which can backfill the wastewater into the pile to supplement the nitrogen source and active microbial resources required for the fermentation of the pile; at the same time, it prevents the wastewater from being directly discharged into the soil and polluting the environment.
