Description

Technical Field

[0001] This utility model relates to the field of organic waste treatment technology, and in particular to a green vermicomposting bin suitable for high organic waste. Background Technology

[0002] With the acceleration of urbanization and the improvement of people's living standards, the output of organic waste is increasing day by day. In real life, this organic waste mainly includes kitchen waste, agricultural waste (such as crop straw, discarded fruits and vegetables, etc.), and landscaping waste. Traditionally, the treatment of this type of waste mainly relies on direct centralized landfill or incineration. However, these two methods not only waste the potential resource value of organic waste, but also cause serious environmental pollution. For example, landfilling produces leachate and the greenhouse gas methane, while incineration releases large amounts of carbon dioxide and other harmful gases.

[0003] In light of the aforementioned problems, composting has become an environmentally friendly and efficient alternative for treating organic waste. Composting is a natural process that decomposes organic matter into stable humus under suitable conditions. This method not only effectively reduces the volume of waste but also transforms it into valuable organic fertilizer, thereby achieving resource recycling.

[0004] However, achieving efficient and rapid composting requires optimal conditions, including suitable temperature, humidity, and ventilation. Traditional, simple composting methods are often inefficient and prone to producing unpleasant odors and breeding grounds for pathogens. Furthermore, most current composting processes are centralized in processing plants, while home or community environments lack adequate composting solutions. Utility Model Content

[0005] The purpose of this invention is to provide a green vermicomposting box suitable for high organic waste, which uses earthworms for small-batch composting to achieve efficient organic waste composting, and is suitable for use in home or community environments.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a green vermicomposting box suitable for high organic waste, comprising a box body, wherein the box body is divided into a composting chamber and a liquid collection chamber located at the upper part by a horizontal partition, the box body is connected to a drain pipe communicating with the lower part of the liquid collection chamber, the drain pipe is provided with a valve, the upper end of the horizontal partition is provided with multiple vertical partitions arranged side by side, the composting chamber is divided into multiple composting chambers by the vertical partitions, the horizontal partition is provided with filter holes at the lower end of each composting chamber, and a filter screen is provided above the filter holes on the horizontal partition;

[0007] The upper end of the housing is provided with an air inlet chamber, and the lower end of the air inlet chamber has multiple air inlets communicating with the interior of the housing. The upper end of the housing is provided with a fan cover communicating with one end of the air inlet chamber. The upper end of the fan cover has a mesh structure, and an electric fan is installed inside the fan cover. An electric heating wire is provided below the electric fan in the air inlet chamber. Ventilation holes are provided on both sides of the housing perpendicular to the vertical partition. An activated carbon filter is provided in each ventilation hole. A water spray pipe is horizontally provided at the top of the housing. The water spray pipe is connected to multiple water spray nozzles. One end of the water spray pipe extends out of the housing and is provided with a solenoid valve.

[0008] By adopting the above technical solution, when using it, waste is added to the composting chamber, and earthworms are added to the composting chamber for composting treatment. During the composting process, the earthworms gradually convert the waste into solid fertilizer and liquid fertilizer. The liquid fertilizer flows through the filter screen and filter holes into the liquid collection chamber for storage.

[0009] During the composting process, the electric fan operates periodically, allowing air to enter the composting chamber from the outside through the air inlet. At the same time, the ventilation holes also facilitate the exchange of air inside and outside the composting chamber, preventing anaerobic fermentation that could lead to odors and composting failure. If the temperature is low during the process, the electric fan and electric heating wire are activated to generate hot air that blows into the composting chamber to increase the internal temperature. If the humidity is too low during the process, the solenoid valve is opened, and water is sprayed through the water spray nozzles to humidify the chamber.

[0010] A further feature of this invention is that: a feeding port is provided at the upper end of the box body, and a feeding cover is hinged to one side of the feeding port; a fertilizer extraction port communicating with the composting chamber is provided on one side of the box body perpendicular to the vertical partition, and a fertilizer extraction cover is hinged to one side of the fertilizer extraction port.

[0011] A further feature of this invention is that the inner edge of the feeding port is provided with a first sealing strip that cooperates with the feeding cover, and the inner edge of the fertilizer extraction port is provided with a second sealing strip that cooperates with the fertilizer extraction cover.

[0012] A further feature of this invention is that each vertical partition has an upward-facing connecting slot on its lower edge, and the upper end of the horizontal partition has multiple connecting strips that correspond one-to-one with the connecting slots.

[0013] A further feature of this invention is that the filter holes are located at one edge of the horizontal partition, and each composting chamber has a filter hole at one end of its lower end.

[0014] A further feature of this invention is that the pore size of the filter screen is 0.5-1mm.

[0015] A further feature of this invention is that the horizontal partition is inclined toward the portion where the filter holes are formed.

[0016] A further feature of this invention is that the side wall of the housing is provided with a temperature and humidity sensor with a probe extending into one of the fertilizer chambers.

[0017] In summary, this utility model has the following beneficial effects:

[0018] Firstly, this utility model uses a small container to compost organic waste. During the process, earthworms decompose the waste into solid fertilizer and liquid fertilizer. At the same time, the waste is automatically classified during the composting process, achieving efficient and rapid composting. It is suitable for use in home or community environments, realizing the recycling of resources.

[0019] Secondly, during the composting process, this utility model can adjust the temperature and humidity of the compost to ensure that earthworms can decompose waste under optimal conditions, effectively improving composting efficiency. At the same time, ventilation is provided to prevent fermentation failure, and activated carbon is used to adsorb the emitted gases to prevent odors from escaping. Attached Figure Description

[0031] Example, refer to Figure 1-6 A green vermicomposting box suitable for high organic waste includes a box body 1. The box body 1 is divided into a composting chamber 12 and a liquid collection chamber 13 by a horizontal partition 11. A drain pipe 14 connected to the lower part of the liquid collection chamber 13 is connected to the box body 1. A valve 15 is installed on the drain pipe 14. A feeding port 16 is opened at the upper end of the box body 1. A feeding cover 17 is hinged to one side of the feeding port 16. A first sealing strip 18 is provided around the inner edge of the feeding port 16 to cooperate with the feeding cover 17. A fertilizer extraction port 19 connected to the composting chamber 12 is opened on the vertical side of the box body 1. A fertilizer extraction cover 110 is hinged to one side of the fertilizer extraction port 19. A second sealing strip 111 is provided around the inner edge of the fertilizer extraction port 19 to cooperate with the fertilizer extraction cover 110. The first sealing strip 18 and the second sealing strip 111 are designed to prevent earthworms from escaping.

[0032] The upper end of the horizontal partition 11 is provided with multiple vertical partitions 2 arranged side by side and perpendicular to the fertilizer inlet 19. Each vertical partition 2 has a connecting slot 21 on its lower edge. The upper end of the horizontal partition 11 is provided with multiple connecting strips 112 corresponding to the connecting slots 21. The composting chamber 12 is divided into multiple composting compartments by the vertical partitions 2. Multiple filter holes 113 are provided at the edge of the horizontal partition 11 away from the fertilizer inlet 19, and the lower end of each composting compartment... The rear end is equipped with filter holes 113. In order to prevent particulate impurities from falling into the liquid collection chamber 13, filter holes 113 are only opened at the rear end, which makes it easier to collect fertilizer and prevents solid fertilizer from getting stuck in the filter holes 113. At the same time, the horizontal baffle 11 is slightly inclined towards the part where the filter holes 113 are opened, so that the filtrate can flow more easily to the filter holes 113 under the action of gravity. A filter screen 3 is set above the filter holes 113 on the horizontal baffle 11. The pore size of the filter screen 3 is 0.5-1mm.

[0033] An air inlet chamber 4 is provided at the upper end of the container 1. Multiple air inlets 41 communicating with the interior of the container 1 are opened at the lower end of the air inlet chamber 4. A fan shroud 5, connected to one end of the air inlet chamber 4, is provided at the upper end of the container 1. The upper end of the fan shroud 5 has a mesh structure, and an electric fan 51 is installed inside the fan shroud 5. An electric heating wire 52 is installed below the electric fan 51 inside the air inlet chamber 4. Two ventilation holes 6 are provided on the rear side of the vertical partition 2 of the container 1 and on the composting cover 110. Each ventilation hole 6 is equipped with an activated carbon filter 61. The ventilation holes 6 increase airflow, and the activated carbon filters 61 are used to adsorb and filter odor gases generated during the composting process. A water spray pipe 7 is horizontally installed at the top of the container 1. The water spray pipe 7 is connected to multiple water spray nozzles 71. One end of the water spray pipe 7 extends out of the container 1 and is equipped with a solenoid valve 72. The outer end of the water spray pipe 7 is connected to tap water. When the humidity is insufficient during the composting process, water is sprayed through the water spray nozzles 71 to increase humidity. A temperature and humidity sensor 8 is installed on the side wall of the container 1, with a probe extending into one of the composting chambers.

[0034] Usage: When using, open the feeding cover 17, add waste through the feeding port 16, and add earthworms in the composting chamber for composting. During the composting process, the earthworms gradually convert the waste into solid fertilizer and liquid fertilizer. The liquid fertilizer flows through the filter screen 3 and filter holes 113 into the liquid collection chamber 13 for storage.

[0035] During the composting process, the electric fan 51 operates periodically, allowing air to enter the composting chamber 12 from the outside through the air inlet 41. At the same time, the ventilation hole 6 also allows the air inside and outside the composting chamber to exchange, preventing anaerobic fermentation from causing odors and composting failure. If the temperature is low during the process, the electric fan 51 and the electric heating wire 52 are turned on to generate hot air to blow into the composting chamber to increase the internal temperature. If the humidity is too low during the process, the solenoid valve 72 is opened, and water is sprayed through the water spray nozzle 71 to humidify.

[0036] After composting is completed, open valve 15 to release the liquid fertilizer in collection chamber 13, open fertilizer outlet 19 to remove vertical partition 2, and take out solid fertilizer from composting chamber one by one.
