Description

Technical Field

[0001] This invention relates to the field of fertilizer fermentation technology, and in particular to a fermentation apparatus for producing organic water-soluble fertilizer. Background Technology

[0002] Currently, fertilizers play a crucial role in agricultural production. Organic water-soluble fertilizer is a water-soluble, multi-element compound fertilizer that is more easily absorbed by crops. It dissolves rapidly in water and has a relatively high absorption and utilization rate. More importantly, it allows for integrated water and fertilizer management, enabling its application in facility agriculture such as sprinkler and drip irrigation, thus saving water. The production process of organic water-soluble fertilizer requires a certain amount of fermenting agent for fermentation, composting, and powdering. Existing fermentation devices add water to the raw materials and then store and stir them in a tank. After stirring is complete, stirring is stopped, allowing the thoroughly stirred organic water-soluble fertilizer to undergo static fermentation within the tank.

[0003] Through long-term practice, the applicant found that organic water-soluble fertilizers often suffer from poor fermentation quality during the fermentation process. Summary of the Invention

[0005] This application provides a fermentation device for producing organic water-soluble fertilizer, which adopts the following technical solution:

[0006] A fermentation apparatus for producing organic water-soluble fertilizer includes a tank having an upper stirring zone and a lower fermentation zone; a movable separating mechanism including a driving component and a separating component, the separating component being movably disposed between the upper stirring zone and the lower fermentation zone, the separating component being used to separate or connect the upper stirring zone and the lower fermentation zone under the action of the driving component; a stirring mechanism installed on the top of the tank for stirring the organic water-soluble fertilizer in the upper stirring zone; a heat exchange and oxygen supply mechanism including a heat exchange component and an oxygen supply component, the heat exchange component being partially located at the center of the lower fermentation zone, the oxygen supply component being installed on the heat exchange component; and a switching on / off mechanism. Installed between a heat exchange component and an oxygen supply component, wherein the heat exchange component is used to cool or heat the organic water-soluble fertilizer in the lower fermentation zone; the switching mechanism has a switchable first state and a second state. During the operation of the heat exchange component, the switching mechanism automatically switches to the first state to connect the oxygen supply component with the lower fermentation zone, thereby allowing the oxygen supply component to introduce oxygen into the organic water-soluble fertilizer in the lower fermentation zone; after the heat exchange component stops operating, the switching mechanism automatically switches to the second state to disconnect the oxygen supply component from the lower fermentation zone, thereby allowing the oxygen supply component to stop introducing oxygen into the organic water-soluble fertilizer in the lower fermentation zone.

[0007] Preferably, the partition assembly includes a guide tube and a bendable component. The guide tube is symmetrically arranged on both outer walls of the tank. From top to bottom, the guide tube includes a vertical pipe section and an arc-shaped pipe section connected sequentially. The end of the arc-shaped pipe section away from the vertical pipe section slopes downwards and communicates with the interior of the tank. The bendable component is slidably disposed within the guide tube. The bendable component includes a limiting membrane sleeve and round rods. Multiple round rods are arranged in parallel, with adjacent round rods rolling against each other. The limiting membrane sleeve seals over the periphery of the multiple round rods, so that the shape of the bendable component matches the internal space of the guide tube and allows it to slide normally within the guide tube. The driving assembly is connected to the bendable component and is used to drive the bendable component to slide within the guide tube.

[0008] Preferably, two guide side grooves are respectively formed on the two opposite inner side walls of the tank. Each guide side groove extends downward at an angle and its top end is connected to the lower opening of the arc-shaped pipe section. The lowest ends of the two guide side grooves on the same inner side wall of the tank are connected and form a V-shape. In the tank, the area above the two guide side grooves in the V-shape is configured as the upper stirring area, and the area below the two guide side grooves in the V-shape is configured as the lower fermentation area.

[0009] Preferably, the limiting membrane sleeve is configured to be made of silicone. When the two sets of bendable parts slide from the guide tube to the lowest end of the guide side groove under the action of the drive assembly, the limiting membrane sleeves on the two sets of bendable parts fit tightly together to seal and separate the upper stirring area and the lower fermentation area.

One end of the transmission pipe is connected to the pump outlet of the water pump, and the other end passes through the lower fermentation area of ​​the tank body and is connected to the second water storage tank. The section of the transmission pipe located in the lower fermentation area is undulating.

[0012] Preferably, the oxygen supply assembly includes a blower and an air supply pipe, the air supply pipe being connected to the blower outlet end of the blower; the transmission pipe has an independent main channel and a secondary channel along its extension direction, the main channel being connected to the pump outlet end of the water pump, the secondary channel being connected to the air supply pipe, and the transmission pipe having a plurality of air outlet holes spaced apart and connected to the secondary channels.

[0013] Preferably, the switching mechanism includes a squeezing component and a blocking component. The squeezing component is disposed inside the transmission pipe and located between the main channel and the secondary channel. The blocking component is slidably disposed inside the secondary channel. In its natural state, the blocking component seals and blocks the vent. When the water pump is started to allow water to flow in the main channel, the squeezing component applies a thrust to the blocking component under water pressure, causing the blocking component to move to a position that allows the vent to connect with the secondary channel. At this time, the switching mechanism is in its first state. When the water pump is turned off to allow no water to flow in the main channel, the squeezing component automatically resets, and the blocking component also automatically resets to the position that seals and blocks the vent.

[0014] Preferably, the extrusion assembly includes an extrusion plate, a torsion spring, an elastic airbag, a limiting frame, and a guide frame. The elastic airbag is in an inflated state and includes a rigid bladder, a first elastic bladder, and a second elastic bladder. The first elastic bladder is connected to the upper end of the rigid bladder, and the second elastic bladder is connected to one side of the rigid bladder. The elasticity of the first elastic bladder is less than that of the second elastic bladder. An opening is formed through the inner wall of the transmission tube between the main channel and the secondary channel. An elastic sealing film is sealed over the opening. When the first elastic bladder bulges upward, it pushes up the elastic sealing film, creating a raised portion of the elastic sealing film within the main channel. The second elastic bladder extends along the secondary channel... The channel extends in a convex direction; the extrusion plate is hinged to the inner wall of the main channel near the secondary channel via a torsion spring, and in its natural state, the extrusion plate is inclined toward the direction of water flow path under the action of the torsion spring, and the extrusion plate abuts against the elastic sealing membrane; the limiting frame is installed in the secondary channel, and the rigid bladder is connected to the limiting frame; the guide frame is installed on the limiting frame and located on the outer periphery of the second elastic bladder, so that the second elastic bladder expands along the length direction of the secondary channel when it expands; when the water pump is started to make water flow in the main channel, the extrusion plate is subjected to water pressure and tilts downward to press the first elastic bladder, so that the first elastic bladder contracts while driving the second elastic bladder to expand along the extension direction of the secondary channel.

[0015] Preferably, the shielding assembly includes a positioning plate, a spring, a sliding post, and a guide block. The sliding post is slidably disposed within the secondary channel along its extension direction and located on one side of the second elastic bladder. The guide block is disposed on the surface of the sliding post. The sliding post is sealed at both ends and hollow internally. An airflow inlet is provided through the side of the sliding post to allow airflow from the secondary channel to enter the interior of the sliding post. An airflow outlet is provided through the lower wall of the sliding post, and the airflow outlet is radially aligned with the air outlet when the sliding post moves along the length of the secondary channel. A guide groove is parallel to the inner wall of the secondary channel near the main channel, and the guide block is slidably inserted into the guide groove. The positioning plate is fixed within the secondary channel at a position where the sliding post is away from the second elastic bladder. The spring connects the positioning plate and the end of the positioning post, and the spring always pushes the sliding post to a position where the airflow outlet is misaligned with the air outlet. When the water pump is started to allow water flow in the main channel, the second elastic bladder expands along the extension direction of the secondary channel and pushes the sliding post to a position where the airflow outlet is radially aligned with the air outlet.

[0016] The present invention has the following advantages and beneficial effects:

[0017] This invention achieves intelligent control of temperature and oxygen supply during the fermentation of organic water-soluble fertilizer through the combined action of a heat exchange component, an oxygen supply component, and a switching mechanism. First, the heat exchange component utilizes a first and second water storage tank, a water pump, and a transmission pipe to circulate cold or hot water in the lower fermentation zone, effectively regulating the temperature. Simultaneously, the transmission pipe employs a dual-channel structure with a main channel for water flow and a secondary channel for airflow. The switching mechanism automatically opens or closes the oxygen supply channel based on the water flow status, enabling the oxygen supply and heat exchange processes to work in synergy and preventing mutual interference. Especially during fermentation, suitable temperature and sufficient oxygen supply promote the activity of aerobic microorganisms, accelerate the degradation of organic matter, and improve fermentation efficiency, while simultaneously reducing the formation of anaerobic environments and decreasing the production of odors and undesirable metabolic products. Therefore, this design not only improves fermentation efficiency but also makes the fermentation process more controllable, contributing to improved quality of the final product.

[0028] In the field of agricultural production, fertilizers play a crucial role in related technologies. Organic water-soluble fertilizers, as a type of multi-component fertilizer that can dissolve in water, are gradually being widely used due to their rapid dissolution and high crop absorption and utilization rates.

[0029] Compared to traditional fertilizers, organic water-soluble fertilizers can effectively achieve integrated water and fertilizer management and are suitable for modern agricultural facilities such as sprinkler and drip irrigation. While improving crop nutrient absorption efficiency, they also achieve water conservation and increased efficiency. In the production process of organic water-soluble fertilizers, the addition of a fermentation agent is a key step. It promotes the decomposition and transformation of organic matter, enabling the fertilizer to reach the ideal degree of composting and further processing it into soluble powder or liquid products.

[0030] However, in the existing technology, the common fermentation device mainly adopts the method of mixing water and raw materials, placing them in a tank and stirring, then stopping the stirring and allowing them to ferment statically. Although this method is simple to operate, in the long-term practice, the applicant found that this process has significant quality problems in actual application, mainly manifested in low fermentation quality, making it difficult to guarantee the final quality of organic water-soluble fertilizer.

[0031] In-depth analysis revealed that the core issue lies in inadequate temperature control and insufficient oxygen supply during fermentation, which negatively impacts microbial activity and reduces fermentation efficiency. Microorganisms are extremely sensitive to environmental temperature during fermentation; excessively high or low temperatures inhibit their growth and metabolism, interfering with the decomposition of organic matter and consequently affecting the fertilizer's maturity. Furthermore, existing fermentation equipment also suffers from insufficient oxygen supply. Uneven oxygen distribution can create anaerobic environments in certain areas, hindering the growth and function of aerobic microorganisms, resulting in uneven fermentation and inconsistent fertilizer quality. Therefore, the deficiencies in temperature control and uniform oxygen supply in existing technologies directly affect the fermentation quality of organic water-soluble fertilizers. Effectively controlling temperature and optimizing oxygen supply during fermentation to ensure a suitable growth environment for microorganisms is a crucial problem that current technology needs to address.

[0032] In view of this, some embodiments of this application provide a fermentation apparatus for producing organic water-soluble fertilizer.

[0033] Please see Figures 1-5 In some embodiments, a fermentation device for producing organic water-soluble fertilizer includes a tank 100, a movable partition mechanism 200, a stirring mechanism 300, a heat exchange and oxygen supply mechanism 400, and a switching mechanism 500. The various components work together to achieve stirring, fermentation, and environmental control of the organic water-soluble fertilizer, thereby improving fermentation efficiency and quality.

[0034] For example, the tank 100 has an upper stirring zone 110 and a lower fermentation zone. Further, the movable partition mechanism 200 includes a drive assembly 210 and a partition assembly 220. The partition assembly 220 is movably disposed between the upper stirring zone 110 and the lower fermentation zone 120. The partition assembly 220 is used to separate or connect the upper stirring zone 110 and the lower fermentation zone 120 under the action of the drive assembly 210.

[0035] For example, the stirring mechanism 300 is installed on the top of the tank 100 and is used to stir the organic water-soluble fertilizer in the upper stirring zone 110. The stirring mechanism 300 is typically implemented by a motor combined with a stirring rod and stirring blades. In some other embodiments, the stirring mechanism 300 may also be implemented by a vibrating motor combined with a vibrating mixing rod.

[0036] For example, the heat exchange and oxygen supply mechanism 400 includes a heat exchange component 410 and an oxygen supply component 420. The heat exchange component 410 is partially located at the center of the lower fermentation zone 120, and the oxygen supply component 420 is mounted on the heat exchange component 410. Furthermore, a switching mechanism 500 is installed between the heat exchange component 410 and the oxygen supply component 420. The heat exchange component 410 is used to cool or heat the organic water-soluble fertilizer in the lower fermentation zone 120. Furthermore, the switching mechanism 500 has a switchable first state and a second state. During the operation of the heat exchange component 410, the switching mechanism 500 automatically switches to the first state to connect the oxygen supply component 420 with the lower fermentation zone 120, thereby allowing the oxygen supply component 420 to introduce oxygen into the organic water-soluble fertilizer in the lower fermentation zone 120. After the heat exchange component 410 stops operating, the switching mechanism 500 automatically switches to the second state to disconnect the oxygen supply component 420 from the lower fermentation zone 120, thereby stopping the oxygen supply component 420 from introducing oxygen into the organic water-soluble fertilizer in the lower fermentation zone 120.

[0037] Specifically, the tank 100 is internally divided into an upper stirring zone 110 and a lower fermentation zone 120, with the connection and isolation between the two zones controlled by the partition component 220 of the movable partition mechanism 200. In practical application, firstly, the drive component 210 drives the partition component 220 to the isolation state, thereby forming relatively independent upper stirring zone 110 and lower fermentation zone 120. Subsequently, raw materials and water are added to the upper stirring zone 110, and the stirring mechanism 300, located at the top of the tank 100, is activated. This mechanism can fully mix the organic water-soluble fertilizer in the upper stirring zone 110, ensuring that water and organic matter are evenly dispersed to form a mixture suitable for fermentation. After stirring is completed, the drive component 210 actuates again, causing the partition component 220 to move to the open state, allowing the stirred organic water-soluble fertilizer to fall naturally into the lower fermentation zone 120 and begin static fermentation. During fermentation, the heat exchange and oxygen supply mechanism 400 plays a crucial role. The heat exchange component 410 is partially located at the center of the lower fermentation zone 120. This location effectively regulates the temperature environment within the lower fermentation zone 120, preventing excessively high or low temperatures from negatively impacting microbial activity. When the temperature in the lower fermentation zone 120 exceeds a preset threshold, cold water is introduced into the heat exchange component 410. This cold water exchanges heat with the organic water-soluble fertilizer within the lower fermentation zone 120, causing the temperature to decrease. Conversely, when the temperature is too low, hot water is introduced to raise the temperature of the lower fermentation zone 120, ensuring a suitable growth environment for the microorganisms. Simultaneously, the operation of the heat exchange component 410 triggers a switching mechanism 500. This switching mechanism automatically switches to a first state during the operation of the heat exchange component 410, connecting the oxygen supply component 420 to the lower fermentation zone 120 and delivering oxygen to the central part of the lower fermentation zone 120. Because the central area of ​​the organic water-soluble fertilizer is prone to forming an anaerobic zone with insufficient oxygen supply during fermentation, this oxygen supply method can effectively improve the uniform distribution of oxygen in the lower fermentation zone 120, avoiding uneven fermentation caused by local hypoxia. When the heat exchange component 410 stops operating, the switching mechanism 500 will automatically switch to the second state, disconnecting the oxygen supply component 420 and stopping the oxygen supply operation, so as to control the timing of oxygen supply and avoid unnecessary energy consumption and the impact of excessive oxygen on certain microorganisms.

[0038] Through the combination of the above structures, the device can achieve automated temperature control and precise oxygen supply during fermentation, ensuring that microorganisms are always in an optimal growth environment, thereby improving the fermentation efficiency and quality of organic water-soluble fertilizer. Furthermore, the introduction of the movable partition mechanism 200 allows the stirring and fermentation processes to be carried out continuously within the same tank 100, reducing the additional equipment and energy consumption required for material transfer. It also avoids the contamination risks caused by multiple transfers in traditional processes, thus optimizing the production process and improving the overall utilization efficiency of the equipment to a certain extent.

[0039] In some implementations, combined with Figure 2 , Figure 3 The partition assembly 220 includes a guide pipe 221 and a bendable component 222. A set of guide pipes 221 are symmetrically arranged on both outer walls of the tank 100. From top to bottom, the guide pipe 221 includes a vertical pipe section 2211 and an arc-shaped pipe section 2212 connected sequentially. The end of the arc-shaped pipe section 2212 away from the vertical pipe section 2211 is inclined downwards and communicates with the interior of the tank 100. Furthermore, the bendable component 222 is slidably disposed within the guide pipe 221. 22 includes a limiting membrane sleeve 2221 and round rods 2222. Multiple round rods 2222 are arranged in parallel and are rolled together between adjacent round rods 2222. The limiting membrane sleeve 2221 seals and covers the periphery of the multiple round rods 2222 so that the shape of the bendable part 222 is adapted to the internal space of the guide tube 221 and slides normally in the guide tube 221. The driving assembly 210 is connected to the bendable part 222 and is used to drive the bendable part 222 to slide in the guide tube 221.

[0040] For example, two guide side grooves 130 are respectively provided on the two opposite inner side walls of the tank 100. Each guide side groove 130 extends downward at an angle and its top end is connected to the lower pipe opening of the arc-shaped pipe section 2212. Furthermore, the lowest ends of the two guide side grooves 130 located on the same inner side wall of the tank 100 are connected and form a V-shape. Furthermore, in the tank 100, the area above the two V-shaped guide side grooves 130 is configured as an upper stirring area 110, and the area below the two V-shaped guide side grooves 130 is configured as a lower fermentation area 120.

[0041] For example, the limiting membrane sleeve 2221 is configured to be made of silicone. When the two sets of bendable parts 222 slide from the guide tube 221 to the lowest end of the guide side groove 130 under the action of the drive assembly 210, the limiting membrane sleeve 2221 on the two sets of bendable parts 222 tightly abuts to seal and separate the upper stirring area 110 and the lower fermentation area 120.

[0042] Based on this, the partition assembly 220 mainly includes a guide tube 221 and a bendable component 222. The guide tubes 221 are symmetrically arranged on both outer walls of the tank 100. Each guide tube 221 consists of a vertical tube segment 2211 and an arc-shaped tube segment 2212. The distal end of the arc-shaped tube segment 2212 slopes downward and communicates with the interior of the tank 100. This structural design allows the bendable component 222 to move smoothly along the path of the guide tube 221 and eventually enter the interior of the tank 100. The bendable component 222 consists of multiple round rods 2222 arranged in parallel and sealed inside the limiting membrane sleeve 2221. Adjacent round rods 2222 are combined in a rolling fit manner, allowing it to bend as the movement path changes.

[0043] Meanwhile, the drive assembly 210 is connected to the bendable component 222, enabling the bendable component 222 to slide along the guide pipe 221. When the bendable component 222 moves vertically downward, it will move sequentially along the vertical pipe section 2211 and the arc-shaped pipe section 2212, and finally enter the tank 100. A guide side groove 130, V-shaped in shape, is provided on the inner wall of the tank 100. Each guide side groove 130 extends downward at an angle, its top end connecting to the outlet of the arc-shaped pipe section 2212. Two guide side grooves 130 located on the same side wall connect at their lowest points, thus forming a V-shaped structure. After entering the tank 100, the bendable component 222 will slide further along the guide side groove 130 and gradually converge towards the bottom of the V-shape until the two sets of bendable components 222 abut against each other at the junction of the bottom of the V-shape. Since the limiting membrane sleeve 2221 is made of silicone, it has a certain degree of flexibility and elasticity. Therefore, when the two sets of bendable parts 222 abut against each other at the bottom of the V-shape, the limiting membrane sleeve 2221 can fit tightly together, thereby playing a sealing role to a certain extent. This allows the upper stirring area 110 and the lower fermentation area 120 to form relatively independent spaces, so as to avoid interference with the fermentation environment during the stirring process.

[0044] On the other hand, when it is necessary to connect the upper stirring zone 110 with the lower fermentation zone 120, the drive assembly 210 can be restarted, causing the flexible component 222 to slide upwards from the V-shaped bottom along the guide side groove 130, and return to the vertical pipe section 2211 through the arc-shaped pipe section 2212, finally exiting the tank 100. In this way, the movement of the flexible component 222 allows for flexible isolation and connection operations between the upper stirring zone 110 and the lower fermentation zone 120, helping to improve the overall operating efficiency of the fermentation device. Compared to traditional mechanical valve structures, this design, due to the combination of the flexible component 222 and the limiting membrane sleeve 2221, results in a more uniform sealing effect, while avoiding the problems of jamming or poor sealing that may occur with rigid structures. Furthermore, since the bendable component 222 is composed of multiple round rods 2222 and is covered by the limiting membrane sleeve 2221, its movement is smoother and it can adapt to the curved shape of the guide pipe 221 and the guide side groove 130, which helps to improve the service life and stability of the partition component 220 without occupying too much space. Therefore, the design of this partition component 220 can not only effectively separate the upper stirring area 110 from the lower fermentation area 120, but also make the connection process more stable, reduce energy consumption, and improve the overall automation level of the device.

[0045] In some implementations, combined with Figure 2 , Figure 3The drive assembly 210 includes a multi-stage cylinder 211, a top plate 212, and connecting rods 213. The multi-stage cylinder 211 is mounted on the top of the tank 100 and arranged vertically, allowing its piston rod to extend and retract vertically. The top of the piston rod of the multi-stage cylinder 211 is connected to the top plate 212, which is placed horizontally and vertically fixed to the piston rod at its center. This design enhances the overall stability to a certain extent and avoids the problem of displacement caused by single-point force. The connecting rods 213 are installed at both ends of the top plate 212 and arranged vertically. The lower end of each connecting rod 213 is connected to the middle of the top of the corresponding bendable component 222. This symmetrical connection helps to ensure the synchronicity and balance of the bendable component 222 during movement. When the piston rod of the multi-stage cylinder 211 extends upward, the top plate 212 moves upward accordingly, and through the connecting rod 213, it drives the flexible part 222 to slide upward along the guide pipe 221, thereby gradually exiting the tank 100 and finally returning to the vertical pipe section 2211, realizing the connection between the upper stirring area 110 and the lower fermentation area 120; when the piston rod of the multi-stage cylinder 211 retracts downward, the top plate 212 moves downward, and the connecting rod 213 drives the flexible part 222 to move downward, so that it enters the tank 100 along the guide pipe 221 until it abuts the bottom of the V-shaped guide side groove 130, thereby completing the separation between the upper stirring area 110 and the lower fermentation area 120. This embodiment uses a multi-stage cylinder 211 with a graded telescopic design to make the movement of the bendable part 222 more stable, avoiding the impact or jamming problems that may be caused by excessively fast movement. At the same time, the setting of the connecting rod 213 enables the power of the cylinder to be evenly transmitted to the bendable part 222, improving the reliability and coordination of the driving process, and thus optimizing the operating efficiency of the entire fermentation device.

[0046] In some implementations, combined with Figure 1 , Figure 2 The heat exchange assembly 410 includes a first water storage tank 411, a water pump 412, a transmission pipe 413, and a second water storage tank 414. The first water storage tank 411 and the second water storage tank 414 are respectively located on both sides of the tank body 100 to form a stable hot water circulation system. The water pump 412 is installed on the outer wall of the first water storage tank 411, and the pump inlet of the water pump 412 is connected to the interior of the first water storage tank 411 through a pipe. One end of the transmission pipe 413 is connected to the pump outlet of the water pump 412, so that the water pump 412 can drive water to flow along the transmission pipe 413 after starting. The other end of the transmission pipe 413 passes through the lower fermentation zone 120 of the tank body 100 and is connected to the second water storage tank 414, forming a complete fluid passage. For example, the section of the transmission pipe 413 located in the lower fermentation zone 120 is undulating.

[0047] With this setup, during the heat exchange process, if it is necessary to lower the temperature of the lower fermentation zone 120, cold water is added to the first water storage tank 411. After the water pump 412 is started, the cold water is transported to the transmission pipe 413. As it flows through the lower fermentation zone 120, it exchanges heat with the surrounding organic water-soluble fertilizer, absorbing some of its heat, thus gradually lowering the temperature of the lower fermentation zone 120. Conversely, if it is necessary to raise the temperature, hot water can be poured into the first water storage tank 411 to achieve the same heating effect. It is worth noting that the section of the transmission pipe 413 within the lower fermentation zone 120 is undulating, meaning that this section is not laid in a straight line but adopts a wavy structure. This design increases the contact area between the heat exchange pipe and the organic water-soluble fertilizer, improving heat exchange efficiency. In addition, the wavy structure can also slow down the water flow rate to a certain extent, increasing the residence time of cold or hot water in the transmission pipe 413, thereby further improving the heat exchange effect. The heat exchange component 410 in this embodiment, through a reasonable water circulation design, makes temperature regulation more stable and improves heat exchange efficiency, making the temperature of the lower fermentation zone 120 easier to control, thereby providing a more suitable environment for the fermentation of organic water-soluble fertilizer.

[0048] In some implementations, combined with Figure 1 , Figure 2 The oxygen supply assembly 420 includes a blower 421 and an air supply pipe 422, with the air supply pipe 422 connected to the blower port of the blower 421. For example, an installation compartment is provided at the upper opening of the first water storage tank 411, where the blower 421 is installed. The air supply pipe 422 passes through the inner wall of the installation compartment in a sealed manner and connects to the secondary channel 4132 within the first water storage tank 411. This ensures that the airflow generated by the blower 421 can directly act on the secondary channel through the air supply pipe 422, without interfering with the water delivery through the transmission pipe 413.

[0049] The transmission pipe 413 has an independent main channel 4131 and a secondary channel 4132 along its extension direction. The main channel 4131 is connected to the pump outlet of the water pump 412, and the secondary channel 4132 is connected to the air supply pipe 422. The transmission pipe 413 has multiple air outlets 4133 that are connected to the secondary channel 4132 at intervals.

[0050] For example, such as Figure 2 , Figure 4 as well as Figure 5 Multiple switching mechanisms 500 are provided at intervals along the section of the transmission pipe 413 located in the lower fermentation zone 120, with each switching mechanism 500 corresponding to one vent 4133. It is worth noting that the switching mechanisms 500 are all located in the straight section of the transmission pipe 413, rather than the curved section.

[0051] Based on this, in the construction of the oxygen supply path, the transmission pipe 413 is divided into two independent channels along its extension direction: the main channel 4131 and the secondary channel 4132. The main channel 4131 is primarily used to transmit the hot water flow between the first water storage tank 411 and the second water storage tank 414, while the secondary channel 4132 serves as an air delivery channel, connected to the air duct 422 of the blower 421. Since the transmission pipe 413's pipe structure penetrates the lower fermentation zone 120, the secondary channel 4132 has multiple air outlets 4133 spaced apart along its extension direction, allowing the air delivered by the blower 421 to enter the lower fermentation zone 120 evenly through these outlets 4133, thereby optimizing the oxygen distribution within the lower fermentation zone 120.

[0052] For example, the vent 4133 is located on the lower end face of the transmission pipe 413, which can effectively prevent organic water-soluble fertilizer from entering the interior of the transmission pipe 413.

[0053] Through this structural design, this embodiment can simultaneously supply oxygen during heat exchange, achieving synergistic optimization of heat exchange and oxygen supply. When the activity of microorganisms is affected by temperature changes during fermentation, the heat exchange component 410 can dynamically adjust the temperature, while the oxygen supply component 420 ensures a continuous supply of oxygen. Especially for localized anaerobic areas that are prone to form in the fermentation material, the spaced-out vents 4133 allow oxygen to enter from different locations, improving the problem of uneven oxygen distribution. In addition, the pneumatic conveying system of the oxygen supply component 420 will not interfere with the hot water flow. Even when the water pump 412 is operating to deliver cold or hot water, the blower 421 can still work independently, continuously supplying oxygen to the lower fermentation zone 120. This design not only improves the efficiency of heat exchange and oxygen supply but also reduces the possibility of interference in the internal piping of the system, making the overall structure more compact and reasonable. It is suitable for application scenarios with high requirements for temperature and oxygen environment during the fermentation of organic water-soluble fertilizers.

[0054] In some implementations, combined with Figure 2 , Figure 4 as well as Figure 5 The switching mechanism 500 includes a squeezing component 600 and a blocking component 700. The squeezing component 600 is disposed in the transmission pipe 413 and located between the main channel 4131 and the secondary channel 4132. The blocking component 700 is slidably disposed in the secondary channel 4132, and in its natural state, the blocking component 700 seals and blocks the air outlet 4133.

[0055] For example, when the water pump 412 is started to allow water to flow in the main channel 4131, the squeezing assembly 600 applies a thrust to the blocking assembly 700 under water pressure, causing the blocking assembly 700 to move to a position where the vent 4133 is connected to the secondary channel 4132. At this time, the switching mechanism 500 is in the first state. Further, when the water pump 412 is turned off to allow no water to flow in the main channel 4131, the squeezing assembly 600 automatically resets, and the blocking assembly 700 also automatically resets to a position that seals and blocks the vent 4133.

[0056] Based on this, the extrusion assembly 600 is located inside the transmission pipe 413, specifically between the main channel 4131 and the secondary channel 4132. Its main function is to respond to changes in water pressure within the main channel 4131 by applying a thrust to the shielding assembly 700, causing the oxygen supply channel to open or close at appropriate times. The shielding assembly 700 is slidably installed within the secondary channel 4132, and in its natural state, i.e., without external force, the shielding assembly 700 maintains its default position, sealing the air outlet 4133 to prevent air from entering the lower fermentation zone 120, and also preventing organic water-soluble fertilizer in the lower fermentation zone 120 from entering the secondary channel 4132.

[0057] When the water pump 412 starts, water begins to flow in the main channel 4131. The water flow exerts pressure on the extrusion assembly 600, causing it to move towards the secondary channel 4132. This, in turn, pushes the shielding assembly 700, exposing the air outlet 4133 and connecting the secondary channel 4132 to the outside. At this time, the air delivered by the blower 421 can smoothly enter the secondary channel 4132 through the air duct 422 and diffuse evenly to the lower fermentation zone 120 through the air outlet 4133, providing oxygen supply for the fermentation material. At this time, the switching mechanism 500 is in the first state, i.e., the oxygen supply passage is open.

[0058] When water pump 412 is turned off, the water flow in the main channel 4131 stops, and the water pressure drops accordingly. The squeezing assembly 600 automatically resets due to the loss of pressure. Simultaneously, the blocking assembly 700 returns to its original position under its own elastic force or gravity, resealing the air outlet 4133, thus disconnecting the oxygen supply channel from the outside and preventing air delivered by blower 421 from entering the lower fermentation zone 120. At this time, the switching mechanism 500 is in its second state, i.e., the oxygen supply channel is closed.

[0059] Through the above structural design, this embodiment automatically starts oxygen supply when the water pump 412 is working and automatically shuts off oxygen supply when the water pump 412 stops, without the need for additional control system intervention. This achieves an intelligent oxygen supply method based on adaptive fluid pressure regulation. This oxygen supply mode can simultaneously supply oxygen when heat exchange demand is high, optimizing the growth environment of microorganisms, improving fermentation efficiency, and avoiding unnecessary air waste when oxygen supply is not needed. In addition, since both the extrusion component 600 and the shielding component 700 are installed inside the transmission pipe 413, the entire mechanism is compact, occupies little space, and will not have a significant impact on the overall layout of the equipment, making it suitable for various fermentation process requirements.

[0060] In some implementations, combined with Figure 2 , Figure 4 as well as Figure 5 The extrusion assembly 600 includes an extrusion plate 610, a torsion spring 620, an elastic airbag 630, a limiting frame 640, and a guide frame 650. The elastic airbag 630 is in an inflated state and includes a rigid bladder 631, a first elastic bladder 632, and a second elastic bladder 633. The first elastic bladder 632 is connected to the upper end of the rigid bladder 631, and the second elastic bladder 633 is connected to one side of the rigid bladder 631. The elasticity of the first elastic bladder 632 is less than that of the second elastic bladder 633. An opening is formed through the inner wall of the transmission pipe 413 between the main channel 4131 and the secondary channel 4132. An elastic sealing film 800 is sealed and covered on the opening. When the first elastic bladder 632 bulges upward, it pushes up the elastic sealing film 800 so that the elastic sealing film 800 forms a raised part in the main channel 4131. The second elastic bladder 633 protrudes along the extension direction of the secondary channel 4132.

[0061] For example, the extrusion plate 610 is hinged to the inner wall of the main channel 4131 near the secondary channel 4132 via a torsion spring 620. Under the action of the torsion spring 620, the extrusion plate 610 is tilted towards the direction of the water flow path in its natural state, and abuts against the elastic sealing membrane 800. Further, a limiting frame 640 is disposed within the secondary channel 4132, and the rigid bladder 631 is connected to the limiting frame 640. A guide frame 650 is disposed on the limiting frame 640 and located on the outer periphery of the second elastic bladder 633, so that the second elastic bladder 633 expands along the length direction of the secondary channel 4132 when it expands. For example, when the water pump 412 is started to allow water to flow in the main channel 4131, the extrusion plate 610 is subjected to water pressure and tilts downwards to press the first elastic bladder 632, causing the first elastic bladder 632 to contract while simultaneously driving the second elastic bladder 633 to expand along the extension direction of the secondary channel 4132.

[0062] In some implementations, combined with Figure 2 , Figure 4 as well as Figure 5 The shielding assembly 700 includes a positioning plate 710, a spring 720, a sliding post 730, and a guide block 740. The sliding post 730 is slidably disposed within the sub-channel 4132 along the extension direction of the sub-channel 4132 and located on one side of the second elastic capsule 633. The guide block 740 is disposed on the surface of the sliding post 730. The two ends of the sliding post 730 are sealed and the interior is hollow. An airflow inlet 731 is provided through the side of the sliding post 730 so that the airflow in the sub-channel 4132 enters the interior of the sliding post 730 through the airflow inlet 731. An airflow outlet 732 is provided through the lower wall of the sliding post 730. The airflow outlet 732 can be radially aligned with the air outlet 4133 when the sliding post 730 moves along the length direction of the sub-channel 4132.

[0063] For example, a guide groove 4134 is provided parallel to the inner wall of the secondary channel 4132 near the main channel 4131, and a guide block 740 is slidably inserted into the guide groove 4134. Further, a positioning plate 710 is fixed within the secondary channel 4132 at a position where the sliding column 730 is away from the second elastic bladder 633. A spring 720 is connected between the positioning plate 710 and the end of the positioning column, and the spring 720 always pushes the sliding column 730 to a position where the air outlet 732 is misaligned with the air outlet 4133. Furthermore, when the water pump 412 is started to allow water to flow in the main channel 4131, the second elastic bladder 633 expands along the extension direction of the secondary channel 4132 and pushes the sliding column 730 to a position where the air outlet 732 is radially aligned with the air outlet 4133.

[0064] Based on this, firstly, when the water pump 412 starts, the water flow in the main channel 4131 pushes the extrusion plate 610 to tilt, causing the extrusion plate 610 to deflect downwards around the hinge point and apply pressure to the elastic sealing membrane 800, causing it to press down and thus causing the first elastic bladder 632 to contract. Since the first elastic bladder 632 is connected to the second elastic bladder 633, and the rigid bladder 631 is in a stable state and will not deform, when the first elastic bladder 632 is compressed, the gas inside it is forced to flow to the second elastic bladder 633, causing the second elastic bladder 633 to expand along the length of the secondary channel 4132. Due to the presence of the limiting frame 640 and the guide frame 650, the expansion direction of the second elastic capsule 633 is restricted, allowing it to extend only along the secondary channel 4132. This avoids uneven expansion or abnormal deformation, thus reliably pushing the sliding column 730 in the shielding assembly 700 to move along the secondary channel 4132, aligning the air outlet 732 with the air outlet 4133, and opening the oxygen supply channel. At this time, the airflow delivered by the blower 421 can enter the secondary channel 4132 along the air duct 422, and sequentially pass through the air inlet 731, the inner cavity of the sliding column 730, the air outlet 732, and the air outlet 4133, finally entering the lower fermentation zone 120. This ensures sufficient oxygen supply to the organic water-soluble fertilizer, helps promote the activity of aerobic microorganisms, improves fermentation efficiency, and reduces the possibility of anaerobic environment formation.

[0065] On the other hand, when the water pump 412 stops working, the water flow in the main channel 4131 disappears, and the extrusion plate 610 loses the water flow driving force, gradually returning to its original tilted state under the action of the torsion spring 620. At the same time, due to the force of the spring 720 on one end of the sliding column 730, the sliding column 730 moves back in the initial direction, causing the air outlet 732 to be misaligned with the air outlet 4133, cutting off the connection between the secondary channel 4132 and the lower fermentation zone 120, stopping the oxygen supply process. Then, the sliding column 730 pushes the second elastic bladder 633 to compress, at which point the first elastic bladder 632 re-expands, lifting the elastic sealing membrane 800, causing the extrusion plate 610 to return to its initial tilted state under the dual pushing action of the first elastic bladder 632 and the torsion spring 620. This design allows the oxygen supply process and the water flow heat exchange process to be linked, avoiding the problem of water flow and air supply occurring simultaneously or interfering with each other, and improving the stability and adaptability of the system operation.

[0066] It is important to note that in the above structure, the elasticity of the first elastic bladder 632 is less than that of the second elastic bladder 633. This design helps to prioritize the compression of the first elastic bladder 632 when the water flow starts, making the airflow regulation more precise, and also improving the reset effect when the water flow stops. Furthermore, the sliding column 730 is sealed at both ends and has an internal cavity, and has an airflow inlet 731 on its side, so that gas can smoothly enter the interior of the secondary channel 4132, and the opening and closing of the airflow channel can be controlled by precise position adjustment. In addition, the guide block 740 of the sliding column 730 cooperates with the guide groove 4134 on the inner wall of the secondary channel 4132 to ensure that the sliding column 730 can slide in the set direction, avoiding problems such as tilting, jamming or positional deviation, thereby improving the reliability of the switching mechanism 500.

[0067] For example, the width of the secondary channel 4132 is greater than the maximum thickness of the elastic airbag 630. Simultaneously, the width of the secondary channel 4132 is also greater than the outer diameter of the sliding column 730 and the width of the positioning plate 710. This ensures that when air flows within the secondary channel 4132, the elastic airbag 630, sliding column 730, and positioning plate 710 are less likely to completely obstruct the airflow, allowing air to flow normally within the secondary channel 4132. Furthermore, the end of the secondary channel 4132 furthest from the air duct 422 is sealed, meaning the secondary channel 4132 does not penetrate the entire transmission pipe 413. This allows the air flowing in the secondary channel 4132 to flow only from the air outlet 4133 into the lower fermentation zone 120.

[0068] In summary, this embodiment achieves automatic control of the oxygen supply process during water flow heat exchange, enabling automatic oxygen replenishment in the fermentation environment of organic water-soluble fertilizer when heat exchange demand is high. This improves fermentation uniformity, enhances the activity of aerobic microorganisms, and reduces the adverse effects of anaerobic environments. Simultaneously, the adaptive adjustment capability of the oxygen supply component 420 and the water flow heat exchange process avoids unnecessary gas waste and improves energy utilization. The compact design of this embodiment, with its small footprint, is applicable to different types of fermentation equipment and has high practical value in real-world applications.

The airflow outlet (732) can be radially aligned with the air outlet (4133) when the sliding column (730) moves along the length direction of the sub-channel (4132). The secondary channel (4132) has a guide groove (4134) parallel to the inner wall of the main channel (4131), and the guide block (740) is slidably inserted into the guide groove (4134); The positioning plate (710) is fixed in the sub-channel (4132) at a position opposite to the second elastic capsule (633) of the sliding column (730). The spring (720) is connected between the end of the positioning plate (710) and the positioning column, and the spring (720) always has the function of pushing the sliding column (730) to a position where the air outlet (732) and the air outlet (4133) are misaligned. When the water pump (412) is started to make water flow in the main channel (4131), the second elastic bladder (633) expands along the extension direction of the secondary channel (4132) and pushes the sliding column (730) to move to a position where the air outlet (732) is radially aligned with the air outlet (4133).
