Description

Technical Field

[0001] This utility model relates to the technical field of agricultural waste resource utilization equipment, and in particular to a modular ceramic composting box. Background Technology

[0002] Organic composting is a biochemical process that utilizes microorganisms widely found in nature to controllably promote the conversion of degradable organic matter in solid waste into stable humus. During organic composting, the compost bin is a closed or semi-closed environment where humidity, oxygen, and temperature are controlled to promote the reproduction and growth of microorganisms, thereby accelerating the decomposition of organic waste.

[0003] However, in practical use, traditional compost bins are mostly one-piece designs with non-adjustable volume, making it impossible to flexibly increase or decrease capacity according to household waste generation or planting needs, limiting their use in small apartments or on balconies. Initial composting materials, the vermicomposting area, and mature organic fertilizer are often stored together, easily leading to uncomposted materials contaminating the mature soil and disrupting the vermicomposting environment, thus reducing decomposition efficiency. Some compost bins are made of plastic, which is prone to aging and damage from long-term contact with organic materials, and its poor breathability leads to oxygen deficiency and decay. Inadequate drainage design prevents excess water from draining in time, easily breeding odors and bacteria. The non-adjustable base results in poor stability when placed on uneven ground. Therefore, there is an urgent need for a modular, clearly zoned, durable, and functionally adaptable composting device. To solve these problems, we propose a modular ceramic compost bin. Utility Model Content

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0030] like Figure 1-5As shown, this utility model embodiment provides a modular ceramic compost bin, including: a module assembly 1, the module assembly 1 including: a module one 11 with a module two 12 disposed on its side, a module two 12 with a module three 13 disposed on its side, the module one 11, the module two 12 and the module three 13 being fixedly connected by corner brackets 15, a movable cover plate 17 being inserted into the module three 13, and a cover body 14 being rotatably disposed on the top of the module one 11, the module two 12 and the module three 13; threaded bases 16 are respectively disposed on the module one 11, the module two 12 and the module three 13. The bottom four corners of module two 12 and module three 13; a connecting component 2 is provided on module component 1, the connecting component 2 including: a drain outlet 21 opened on module one 11; an earthworm island 23 disposed inside module two 12; a sliding groove 25 opened on the side wall connecting module one 11 and module two 12; a partition 251 is slidably connected to the sliding groove 25 via a sliding rail 252, the partition 251 is provided in three pieces, each corresponding to a different height, and a partition 251 of fixed height is provided between module two 12 and module three 13. Optionally, a filter screen is provided inside the drain outlet 21. Optionally, a circular groove 231 is provided on the top surface of the bottom plate of module two 12, the circular groove 231 and the bottom of the earthworm island 23 are inserted into it.

[0031] Modules 11, 12, and 13 in Module Component 1 are made entirely of ceramic, featuring high temperature resistance (-20℃~80℃), corrosion resistance (resistant to organic acids and microbial erosion), and moderate air and water permeability (ceramic porosity 8%~12%, promoting an aerobic environment for composting). Their surfaces are glazed, with smooth, easy-to-clean outer walls and anti-slip textures on the inner walls. This device uses three modules as the basic unit (expandable to more modules), each module measuring 45cm×45cm×45cm (length×width×height). Modules are connected by interlocking snap-fit ​​structures on the side walls. The number of modules can be increased or decreased as needed (e.g., 1-2 modules for small-scale home use, expanding to 4-5 modules for large-scale planting). Taking this device as an example, the three modules are, in order, the composting area, the vermicompost area, and the mature soil area, separated by detachable partitions. Specific functions and structures are as follows:

[0032] Composting area: Used for the initial composting of organic waste (kitchen waste, fallen leaves, etc.). A 15mm diameter drain outlet is provided at the bottom corner, with a built-in 304 stainless steel filter screen (0.5mm pore size) to prevent the loss of solid materials and drain excess seepage; two 10mm diameter ventilation holes are provided on the side wall 5cm from the bottom to promote air circulation.

[0033] Vermicomposting zone: Used for further decomposition of pre-composted materials by earthworms. The partition 251 separating it from the composting zone is adjustable: three sets of grooves 25 (corresponding to heights of 5cm, 10cm, and 15cm respectively) are provided on both sides of the partition. The height is fixed by inserting the partition 251 into the grooves 25, allowing for easy control of the connection between the two zones based on the amount of material. Combined with the breathability of the ceramic material, this provides a suitable living environment for earthworms. To address the problem of waterlogging in the vermicomposting zone during the rainy season or excessive watering, leading to earthworm death due to oxygen deprivation, a removable earthworm island 23 is added inside the vermicomposting zone. The island is hollow and filled with dry coconut coir (water-retaining but not waterlogged), providing earthworms with a moist but not waterlogged emergency habitat. Its conical side forms a 5cm gap with the sidewall of the vermicomposting zone, allowing earthworms to freely move between the material and the earthworm island 23 under normal conditions without interfering with their decomposition activities.

[0034] Mature Soil Zone: Used to store mature organic fertilizer decomposed by earthworms. The partition 251 between the earthworm soil zone and the earthworm soil zone is at a fixed height (10cm) to prevent incompletely decomposed materials from entering; a movable cover 17 (made of the same material as the box body) is provided on the side. The movable cover 17 is inserted into module three 13. When the user needs to take soil, the movable cover 17 is pulled upward to expose space so that the mature soil can roll down for easy soil removal.

[0035] Assembly: The user selects 3 modules according to the needs and connects them into a whole through the corner bracket 15; adjust the threaded base 16 to be stable, and insert the partition 251 between the composting area, the vermicompost area and the mature soil area into the corresponding slots (the partition 251 between the composting area and the vermicompost area is initially set to a height of 10cm).

[0036] Usage: Add kitchen waste, fallen leaves, etc. to the composting area and spray a small amount of water to keep it moist (humidity 60%-70%); after the material has initially decomposed (about 2 weeks), lower the partition 251 between the composting area and the vermicomposting area to 5cm to allow the material to enter the vermicomposting area; put earthworms into the vermicomposting area (10 earthworms per 10L of material), close the cover, and maintain air circulation through the ventilation holes; after about 4 weeks, the material decomposed by the earthworms will enter the mature soil area through the 10cm high partition, and the organic fertilizer can be taken out by opening the movable cover 17 of the mature soil area.

[0037] Alternatively, the cover 14 may be equipped with a cross-shaped positioning frame 24. Depending on the load-bearing requirements or the material of the cover 14, a cross or grid-shaped reinforcing positioning frame (made of galvanized flat iron strip, 20mm wide) may be embedded in the middle of the top of the cover. The iron strip is fixed to the cover 14, and the load-bearing capacity is ≥15kg (for temporary placement of tools or a small amount of materials).

[0038] Alternatively, the earthworm island 23 is an irregular column with multiple channels. The earthworm island 23 is made of the same ceramic material as the box body, which ensures that earthworms can pass through while maintaining internal dryness.

[0039] Alternatively, the top of the earthworm island 23 is higher than that of module 2 12. The bottom center of the earthworm soil area is circular, and the top is 3cm higher than the highest storage surface of the earthworm soil area, forming a "dry refuge" independent of the wet material.

[0040] Alternatively, the threaded base 16 may be equipped with a rubber anti-slip pad at its bottom. The rubber anti-slip pad at the bottom of the support legs allows for adaptation to uneven ground, while also raising the bottom of the housing to enhance ventilation and drainage.

[0041] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
