Description

Technical Field

[0001] This utility model relates to the field of aerobic composting technology, and in particular to a sequencing batch non-powered aerobic fermentation device. Background Technology

[0002] Agricultural waste mainly refers to organic, easily degradable waste such as livestock and poultry manure, crop straw, vegetable scraps, and kitchen waste generated during agricultural production. After harmless treatment, it can be converted into organic fertilizer. Currently, the main treatment method for agricultural waste is aerobic composting. For example, many agricultural planting areas collect waste such as melon vines and vegetable scraps from the field, crush and sieve them, add microbial agents, and mix them with livestock and poultry manure to establish windrow fermentation piles. After aerobic fermentation and secondary aging, biological humus is formed, which is then returned to the field in conjunction with the agricultural season to achieve recycling.

[0003] Currently, most aerobic composting equipment uses large, sealed containers. Agricultural waste is loaded into these containers and left to mature for a period of time before being discharged in a unified manner. For users who generate less agricultural waste and have a smaller demand for organic fertilizer, it is difficult to flexibly achieve small-scale feeding and discharging. Utility Model Content

[0044] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0045] The following is combined Figures 1-5 The sequential batch aerobic fermentation device with non-powered ventilation provided by the present invention will be described in detail through specific embodiments and application scenarios.

[0046] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this embodiment provides a sequencing batch aerobic fermentation device with non-powered ventilation, including: a composting bin 1, a fermentation trolley 2, a non-powered ventilation component 3, and an odor treatment component 4.

[0047] The compost bin 1 includes a base plate 11, a bin body 12, and a bin cover 13; the bin body 12 surrounds the base plate 11, and the bin cover 13 covers the bin body 12.

[0048] The housing 12 includes a main body 121, a first opening and closing door 122, and a second opening and closing door 123.

[0049] The main body 121 has a first opening and a second opening at its two ends respectively. The first opening is provided with a first opening and closing door 122, which is used to open or close the first opening. The second opening is provided with a second opening and closing door 123, which is used to open or close the second opening.

[0050] A slide rail 14 is provided along the length of the base plate 11. Multiple fermentation carts 2 are provided, and multiple fermentation carts 2 are arranged sequentially along the length of the slide rail 14 and can move along the slide rail 14.

[0051] The first opening is the entrance to multiple fermentation carts 2, and the second opening is the exit to multiple fermentation carts 2.

[0052] The non-powered ventilation component 3 is installed in the compost bin 1, and the non-powered ventilation component 3 and the odor treatment component 4 are connected.

[0053] Understandably, the sequencing batch aerobic fermentation device provided by this invention is used to treat agricultural waste, which can be biodegradable organic waste rich in microorganisms, such as livestock and poultry manure, crop straw, vegetable scraps, and kitchen waste. In the composting device, the agricultural waste will be decomposed by beneficial microorganisms, transforming it into useful biogas and fertilizer. During fermentation, a certain temperature and humidity supply is required, and the agricultural waste to be fermented needs to be kept warm to ensure effective fermentation.

[0054] In this embodiment, the compost bin 1 has a base plate 11, a body 12, and a lid 13 forming a sealed space that promotes the natural fermentation of biological waste. Specifically, the base plate 11, body 12, and lid 13 are all made of insulation board, which enhances the insulation performance of the compost bin 1, increases the internal temperature of the compost bin 1, accelerates the decomposition of organic matter by microorganisms, and thus speeds up the composting process.

[0055] The fermentation cart 2 can hold a certain volume of agricultural waste. A fermentation cart 2 filled with agricultural waste enters the compost bin 1 through the first opening / closing door 122. Then, a second fermentation cart 2 arrives at the first opening / closing door 122. The first fermentation cart 2 moves one cart length towards the second opening / closing door 123, and the second fermentation cart 2 enters the compost bin 1 through the first opening / closing door 122. Then, a third fermentation cart 2 arrives at the first opening / closing door 122, and the above process is repeated until the last fermentation cart 2 enters the compost bin 1. The fermentation cart 2 closest to the second opening / closing door 123 leaves the compost bin 1 through the second opening / closing door 123. The remaining fermentation carts 2 sequentially move one cart length towards the direction closest to the second opening / closing door 123, creating an empty space in the compost bin 1 near the first opening / closing door 122. Another fermentation cart 2 enters the compost bin 1 through the first opening / closing door 122 to fill the empty space.

[0056] In this embodiment, the capacity of the fermentation cart 2 is smaller than that of the entire compost bin 1. If the fermentation carts 2 enter the compost bin 1 at different times, the maturation time within the compost bin 1 will also differ. The first fermentation cart 2 to enter the compost bin 1 is positioned closest to the second opening / closing door 123, allowing it to exit the compost bin 1 first through the second opening / closing door 123. Therefore, for household needs where daily agricultural waste and fertilizer requirements are relatively low, agricultural waste can be composted in batches and at different times using the fermentation cart 2 as a unit. This flexibly achieves measured feeding and discharging, meeting the needs of household users.

[0057] External air enters the compost bin 1 through the non-powered ventilation component 3, which then exhausts the heat generated during fermentation. The suction force provided by the non-powered ventilation component 3 accelerates the entry of external air into the compost bin 1, enhances gas exchange between the inside and outside of the compost bin 1, and ensures timely replenishment of oxygen, preventing oxygen deficiency inside the compost bin 1 and accelerating the degradation and maturation of organic matter.

[0058] Because the gas inside compost bin 1 exchanges frequently with the outside gas, the organic matter degradation and maturation process will produce odors, and direct emission will pollute the environment.

[0059] Furthermore, this embodiment also includes an odor treatment component 4, which is located in the air outlet duct 32. The odor treatment component 4 eliminates the odor generated in the compost bin 1 before it is discharged, thereby achieving the deodorization effect and preventing the gas discharged from the compost bin 1 from polluting the environment.

[0060] In practical applications, the agricultural waste in this embodiment is first processed by crushing one or more raw materials to below 5cm, adjusting the moisture content to 60%, and mixing them evenly. The mixed agricultural waste is then loaded into a fermentation cart 2, and the cart is sent into the composting bin 1 through the first opening and closing door 122. The agricultural waste is loaded into the fermentation cart 2 in sequence according to the amount generated, and the cart is moved on the slide rail 14 towards the direction of the second opening and closing door 123 so that the order in which multiple carts are installed is arranged on the slide rail 14. The agricultural waste is allowed to ferment naturally in the composting bin 1. Once the organic matter has degraded and matured, the second opening and closing door 123 is opened, and the fermentation cart 2 closest to the second opening and closing door 123 is moved out of the composting bin 1. The remaining multiple fermentation carts 2 are moved one cart length towards the second opening and closing door 123. The empty fermentation cart 2 is used to carry newly generated agricultural waste and to carry out a new round of fermentation cycle.

[0061] The sequential batch aerobic fermentation device provided by this utility model, by setting up multiple fermentation carts 2 and a slide rail 14 inside the composting bin 1, allows the multiple fermentation carts 2 to be arranged sequentially on the slide rail 14 and move along the slide rail 14. A first opening and closing door 122 is set on the composting bin 1 as the entrance of the fermentation carts 2, and a second opening and closing door 123 is set as the exit of the fermentation carts 2. This allows the fermentation carts 2 carrying agricultural waste to enter the composting bin 1 sequentially through the second opening and closing door 123 at different times and leave the composting bin 1 sequentially at different times. This realizes the time-based and quantity-based start of composting of agricultural waste and the time-based and quantity-based acquisition of the generated organic fertilizer, achieving flexible composting treatment to meet the composting needs of households.

[0062] like Figure 5 As shown, the fermentation cart 2 in this embodiment includes a cart body 21 and rollers 22.

[0063] The trolley body 21 is a square trough, which is used to carry agricultural waste. The rollers 22 are rotatably located at the bottom of the support plate.

[0064] Understandably, the roller 22 can move along the slide rail 14 to limit the movement path of the fermentation cart 2, ensuring that the fermentation cart 2 can move along the length of the box 12 inside the composting box 1 without deviating or tilting.

[0065] The square trough can hold a certain volume of agricultural waste. Since the volume of the square trough in each fermentation cart 2 is equal, the fermentation days of each fermentation cart 2 can be calculated, and the mature organic fertilizer can be removed from the composting bin 1 at the appropriate time.

[0066] like Figure 5 As shown, the square trough in this embodiment has a grid plate on its side and a support plate on its bottom.

[0067] The load-bearing plate is a solid plate.

[0068] Understandably, since agricultural waste carried in the square tank of the fermentation cart 2 will generate leachate during fermentation, the pores of the grid plate allow the leachate to pass through the pores and drip onto the bottom plate 11. The supporting plate is a solid plate, which can prevent agricultural waste from slipping and ensure the effective separation of solid and liquid agricultural waste.

[0069] The sequencing batch non-powered aerobic fermentation device of this embodiment also includes: a first driving component.

[0070] Multiple first driving components are provided, each first driving component is provided on each trolley body 21, and the first driving component is connected to the roller 22 for transmission.

[0071] Understandably, in an alternative embodiment, each trolley body 21 is provided with a first drive member for driving the roller 22 to rotate.

[0072] This embodiment also includes a controller, which is electrically connected to each of the first driving components. The controller can control the moving speed and moving distance of each fermentation cart 2 according to the required moving distance of each fermentation cart 2, thereby achieving flexible control over the movement of each fermentation cart 2.

[0073] Specifically, the first driving component can be a motor.

[0074] The sequencing batch non-powered aerobic fermentation device of this embodiment also includes: a chain, a sprocket, and a second drive component.

[0075] The second drive unit is installed in the compost bin 1. The second drive unit is connected to the sprocket drive. The chain is wound around the sprocket and connected to multiple trolley bodies 21.

[0076] Understandably, the second drive unit is used to drive the rotation of the sprocket, which in turn drives the chain to move, thereby driving the movement of multiple trolley bodies 21.

[0077] Specifically, the second driving component can be a motor.

[0078] Furthermore, the non-powered ventilation assembly 3 of this embodiment includes an air inlet pipe 31, an air outlet pipe 32, a ventilation pipe, and a non-powered ventilator 33. The air inlet pipe 31 is located on the lower side of the housing 12, the air outlet pipe 32 is located on the housing cover 13, the non-powered ventilator 33 is installed at the top of the air outlet pipe 32, the ventilation pipe is located inside the housing 12, and the ventilation pipe and the air outlet pipe 32 are connected.

[0079] Air entering the composting bin 1 through the air inlet duct 31 is discharged into the interior of the composting bin 1 through the ventilation duct. The heat generated during fermentation enters the air outlet duct 32 through the ventilation duct and is discharged to the outside under the suction of the non-powered fan.

[0080] The non-powered blower utilizes natural wind speeds to drive the turbine rotation and promote air convection inside and outside the compost bin 1. It accelerates and transforms any parallel airflow into a vertical upward flow, improving ventilation within the compost bin 1. In other words, the non-powered blower creates suction, accelerating the entry of external air into the compost bin 1, enhancing gas exchange, and ensuring timely oxygen replenishment. This prevents oxygen deficiency inside the compost bin 1 and accelerates the degradation and maturation of organic matter.

[0081] Specifically, a non-powered fan can be a wind cap.

[0082] In this embodiment, there are multiple air inlet pipes 31, air outlet pipes 32, ventilation pipes, and non-powered ventilators 33.

[0083] Multiple air inlet ducts 31 are spaced apart along the length of the housing 12, and multiple non-powered ventilators 33 are correspondingly installed with multiple air outlet ducts 32. Each ventilator is connected to its corresponding air outlet duct 32.

[0084] Multiple air inlet pipes 31 can be arranged in an array along the length of the container 12. Multiple air inlet pipes 31 can simultaneously draw in more external air, which helps to enhance the disturbance of internal and external air, increase the oxygen inside the composting container 1, and help to accelerate the degradation and maturation of organic matter.

[0085] At the same time, multiple ventilation pipes, multiple air outlet pipes 32 and multiple non-powered ventilators 33 can also accelerate the disturbance of internal and external air, making the aerodynamic field inside the composting bin 1 more active, strengthening the exchange of internal and external air, and promoting the rapid degradation and fermentation of organic matter.

[0086] The odor treatment component 4 in this embodiment includes an air inlet pipe, a collection tower, and an exhaust pipe.

[0087] The air inlet pipe and the exhaust pipe are connected to the air outlet pipe 32 and the collection tower, respectively, and the collection tower is filled with packing material.

[0088] Understandably, the collection tower can collect the odors produced during fermentation to purify the air discharged into the surrounding environment through the exhaust duct 32. The collection tower is equipped with packing material that can adsorb the odors. Specifically, the adsorption tower can be equipped with multi-stage biochar filter media, and multi-stage adsorption ensures complete adsorption of the odors.

[0089] like Figure 1 As shown, the sequencing batch aerobic fermentation device without power ventilation in this embodiment also includes: a storage tank, a spray pipe, and a spray head.

[0090] The liquid storage tank is located on the outside of the composting tank 1, and the nozzle is located on the top of the composting tank 1. The spray pipe is connected to the liquid storage tank and the nozzle respectively.

[0091] Understandably, during the fermentation of agricultural waste, a suitable moisture content is more conducive to the growth, reproduction, and metabolism of microorganisms, thereby accelerating the decomposition of organic matter and improving the composting maturity.

[0092] The storage tank is used to store the spray solution injected into agricultural waste. The spray solution is sprayed into the agricultural waste through the spray pipe from the nozzle.

[0093] Optionally, multiple nozzles can be set, with the nozzles spaced apart along the length of the container 12, to ensure uniform spraying within the composting container 1 during spraying and to ensure consistent moisture content within the composting container 1.

[0094] In this embodiment, the base plate 11 is inclined relative to the horizontal plane. The sequencing batch aerobic fermentation device also includes a collection pipe and a collection box. The collection pipe is located at the lowest point of the base plate 11 and is connected to the collection box.

[0095] Understandably, leachate is produced during composting. Leachate contains high concentrations of organic matter, ammonia nitrogen, and heavy metals. If it is not collected and seeps directly into the soil, it will cause soil pollution and also pollute groundwater.

[0096] In this embodiment, the leachate produced during fermentation falls onto the bottom plate 11. Because the bottom plate 11 is sloped, the leachate on it flows down the slope towards the collection pipe at a lower elevation. Finally, the leachate flows into the collection tank through the collection pipe, completing the collection of the leachate.

[0097] The sequencing batch non-powered aerobic fermentation device in this embodiment also includes a liquid pump and a delivery pipe.

[0098] The delivery pipe is connected to the collection tank and the storage tank respectively, and the liquid pump is installed on the delivery pipe.

[0099] Understandably, since the leachate in the collection tank can be transported to the storage tank through a delivery pipe, and then sprayed again onto the agricultural waste during the fermentation process via nozzles, the leachate is reused. Re-spraying the leachate into the compost material increases its moisture content, providing a suitable environment for microbial growth and reproduction, thereby accelerating the decomposition of organic matter and promoting compost maturation. Furthermore, the nitrogen, phosphorus, and potassium nutrients contained in the leachate can be returned to the compost material through re-spraying, preventing nutrient loss and improving the compost's fertilizer efficiency.

[0100] The sequencing batch aerobic fermentation device without power ventilation in this embodiment also includes a temperature sensor and a display.

[0101] The temperature sensor is located in compost bin 1, and the temperature sensor and the display are electrically connected.

[0102] Understandably, the optimal temperature during composting is 55℃~60℃. Within this temperature range, there is a rich variety, large quantity, and high activity of microorganisms, which can ensure a high rate of organic matter degradation. At the same time, it can also kill parasites, pathogens, and harmful bacteria in agricultural waste, thus achieving harmless composting.

[0103] A temperature sensor is used to monitor the temperature changes of the compost material in compost bin 1 in real time and display the data on a monitor. Users can intuitively read the temperature of the compost material in compost bin 1 from the monitor and take appropriate measures to bring the temperature back to the suitable range when the temperature is too low or too high, so as to achieve reasonable temperature control of the compost material.

[0104] The sequencing batch non-powered aerobic fermentation device in this embodiment also includes a fixed frame.

[0105] A fixed frame is installed around the outside of compost bin 1.

[0106] Understandably, the fixed frame is used to fix the base plate 11, the box body 12 and the box cover 13, making the connection between the base plate 11, the box body 12 and the box cover 13 more stable and reliable.

[0107] Specifically, the fixed frame includes connecting pipes, elbows, and fasteners. The connecting pipes form a three-dimensional frame structure, the elbows are used to connect the bent parts, and the fasteners are used to connect and fix the connecting pipes and elbows.

[0108] The sequencing batch non-powered aerobic fermentation device in this embodiment also includes: a heat insulation film.

[0109] The insulation film is rolled around the bottom of one side of the fixed frame. When the insulation film is stretched, it covers the outside of the fixed frame, thus covering the compost bin 1 inside.

[0110] When the insulation film is rolled up, it is stored at the bottom of the fixed frame.

[0111] Understandably, in order to ensure that the temperature inside the compost bin 1 is maintained at 55℃~60℃ during winter or periods of low temperature, this embodiment is equipped with an insulation film for heat preservation during the fermentation process.

[0112] When the temperature is high, the insulation film is rolled up and stored at the bottom of the fixed frame. When the temperature is low, the insulation film is stretched and covers the entire compost bin 1. With the support of the fixed frame, the insulation film insulates the compost bin 1.

[0113] Specifically, the insulation film can be a polyethylene insulation film.

[0114] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
