It will be apparent that the described embodiments are only some, but not all, embodiments of the invention. All other embodiments, based on the examples herein, which are within the scope of the invention as defined by the claims, will be within the scope of the invention as defined by the claims.

The terms first, second and the like in the description and in the claims, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged, as appropriate, such that embodiments of the present application may be implemented in sequences other than those illustrated or described herein, and that the objects identified by "first," "second," etc. are generally of a type, and are not limited to the number of objects, such as the first object may be one or more. Furthermore, in the description and claims, "and/or" means at least one of the connected objects, and the character "/", generally means that the associated object is an "or" relationship.

In the related art, in the field of agricultural production, the effect of the fertilizer is important, and the organic water-soluble fertilizer is used as a water-soluble multi-element compound fertilizer, and is gradually widely applied due to the characteristics of rapid dissolution and high crop absorption and utilization rate.

Compared with the traditional fertilizer, the organic water-soluble fertilizer can effectively realize the integration of the water and the fertilizer, is suitable for modern agricultural facilities such as spray and drip irrigation, and achieves the purposes of saving water and improving efficiency while improving the nutrient absorption efficiency of crops. In the production process of the organic water-soluble fertilizer, the addition of the fermenting agent is a key link, and the fermenting agent promotes the decomposition and conversion of organic matters, so that the fertilizer reaches the ideal decomposition degree and is further processed into soluble powdery or liquid products.

However, in the prior art, a common fermentation device mainly adopts a mode of mixing water and raw materials, then placing the mixed water and raw materials in a tank body for stirring, and then stopping stirring and performing standing fermentation, and although the mode is simple and convenient to operate, in a long-time practical process, the applicant finds that the process has a significant quality problem in practical application, and the quality of the fermentation is mainly low, so that the final quality of the organic water-soluble fertilizer is difficult to ensure.

Through intensive analysis, the core of the problem is found that the temperature regulation in the fermentation process is poor and the oxygen supply is insufficient, so that the microbial activity is influenced, and the fermentation efficiency is reduced. The microorganism is extremely sensitive to the ambient temperature in the fermentation process, and the too high or too low temperature can inhibit the growth and metabolism of the microorganism, so that the decomposition process of the organic matters is disturbed, and the decomposition degree of the fertilizer is further influenced. In addition, the existing fermentation device has the defect of insufficient oxygen supply, and partial areas can form anaerobic environment due to uneven oxygen distribution, so that the growth and the action of aerobic microorganisms are affected, the fermentation is uneven, and the quality of the final fertilizer is uneven. Therefore, the defects of the prior art in the aspects of temperature control and uniform oxygen supply directly affect the fermentation quality of the organic water-soluble fertilizer, so how to effectively regulate and control the temperature and optimize the oxygen supply in the fermentation process, so that microorganisms are always in a proper growth environment, and the method is an important problem to be solved in the prior art.

In view of this, some embodiments of the present application provide a fermentation apparatus for producing an organic water-soluble fertilizer.

Referring to fig. 1 to 5, in some embodiments, a fermentation device for producing an organic water-soluble fertilizer includes a tank 100, a movable separation mechanism 200, a stirring mechanism 300, a heat exchange and oxygen supply mechanism 400, and a switching on/off mechanism 500, and all the components cooperate with each other, so that stirring, fermentation and environmental regulation of the organic water-soluble fertilizer are realized, and fermentation efficiency and quality are improved.

Illustratively, the tank 100 has an upper agitation area 110 and a lower fermentation area. Further, the movable partition mechanism 200 includes a driving component 210 and a partition component 220, the partition component 220 is movably disposed between the upper stirring area 110 and the lower fermentation area 120, and the partition component 220 is used for partitioning or communicating the upper stirring area 110 and the lower fermentation area 120 under the action of the driving component 210.

Illustratively, a stirring mechanism 300 is mounted on top of the tank 100 and is used to stir the organic water-soluble fertilizer within the upper stirring zone 110. Stirring mechanism 300 is typically implemented as a motor in combination with a stirring rod and stirring blade. In some other embodiments, the stirring mechanism 300 may also be implemented for a vibrating motor in combination with a vibrating stirring rod.

Illustratively, the heat exchange and oxygen supply mechanism 400 includes a heat exchange assembly 410 and an oxygen supply assembly 420, the heat exchange assembly 410 being partially located at the center of the lower fermentation region 120, the oxygen supply assembly 420 being mounted on the heat exchange assembly 410. Further, the switching on-off mechanism 500 is installed between the heat exchange assembly 410 and the oxygen supply assembly 420, the heat exchange assembly 410 is used for cooling or heating the organic water-soluble fertilizer in the lower fermentation area 120, further, the switching on-off mechanism 500 has a switchable first state and a switchable second state, in the operation process of the heat exchange assembly 410, the switching on-off mechanism 500 is automatically switched to the first state so as to enable the oxygen supply assembly 420 to be communicated with the lower fermentation area 120, and therefore oxygen is introduced into the organic water-soluble fertilizer in the lower fermentation area 120 by the oxygen supply assembly 420, after the heat exchange assembly 410 stops operating, the switching on-off mechanism 500 is automatically switched to the second state so as to disconnect the oxygen supply assembly 420 from the lower fermentation area 120, and further, the oxygen supply assembly 420 stops introducing oxygen into the organic water-soluble fertilizer in the lower fermentation area 120.

Specifically, the interior of the tank 100 is divided into an upper agitation area 110 and a lower fermentation area 120, and communication and isolation of both are controlled by moving the partition member 220 of the partition mechanism 200. In practical application, first, the driving assembly 210 drives the partition assembly 220 to be in a partition state, so as to form the relatively independent upper stirring area 110 and lower fermentation area 120. Subsequently, the raw materials and water are added to the upper stirring zone 110, and the stirring mechanism 300 is started, and the stirring mechanism is positioned at the top of the tank body 100, so that the organic water-soluble fertilizer in the upper stirring zone 110 can be fully mixed, and the water and the organic matters are uniformly dispersed to form a mixture suitable for fermentation. When the stirring is completed, the driving assembly 210 is again operated to move the partition assembly 220 to the opened state, so that the stirred organic water-soluble fertilizer naturally falls down to the lower fermentation area 120 and starts to stand still for fermentation. In the fermentation process, the heat exchange and oxygen supply mechanism 400 plays a key role, wherein the heat exchange component 410 is partially arranged at the center of the lower fermentation area 120, and the position can effectively adjust the temperature environment in the lower fermentation area 120, so that the influence of the local too high or too low temperature on the microbial activity is avoided. When the temperature of the lower fermentation area 120 is detected to be higher than the preset threshold value, cold water is introduced into the heat exchange assembly 410 and exchanges heat with the organic water-soluble fertilizer in the lower fermentation area 120 to promote the temperature to be reduced, otherwise, when the temperature is too low, hot water is introduced to conduct heat exchange to promote the temperature of the lower fermentation area 120, so that microorganisms are always in a proper growth environment. Meanwhile, the operation of the heat exchange assembly 410 triggers the switching on/off mechanism 500, and the switching on/off mechanism 500 can be automatically switched to the first state when the heat exchange assembly 410 is operated, so that the oxygen supply assembly 420 is communicated with the lower fermentation area 120, and oxygen is conveyed to the middle position of the lower fermentation area 120. Because the middle area of the organic water-soluble fertilizer is easier to form an anaerobic area with insufficient oxygen supply in the fermentation process, the oxygen supply mode can effectively promote the uniform distribution of oxygen in the lower fermentation area 120 and avoid the uneven fermentation phenomenon caused by partial oxygen deficiency. When the heat exchange assembly 410 stops operating, the switching on/off mechanism 500 will automatically switch to the second state to disconnect the oxygen supply assembly 420 and stop the oxygen supply operation, so as to control the timing of oxygen supply and avoid unnecessary energy consumption and the influence of excessive oxygen on certain microorganisms.

Through the cooperation of above-mentioned structure, the device can realize automatic control by temperature change and accurate oxygen suppliment in fermentation process, makes the microorganism be in better growing environment all the time to promote organic water-soluble fertile fermentation efficiency and quality. In addition, the introduction of the movable separation mechanism 200 enables the stirring and fermentation processes to be continuously carried out in the same tank body 100, reduces the consumption of additional equipment and energy required by material transfer, and simultaneously avoids the pollution risk caused by multiple transfer in the traditional process, thereby optimizing the production flow to a certain extent and improving the comprehensive utilization efficiency of the equipment.

In some embodiments, referring to fig. 2 and 3, the partition assembly 220 includes a guide through pipe 221 and a bendable piece 222, the guide through pipe 221 is symmetrically provided with a group on two outer walls of the tank body 100, the guide through pipe 221 includes a vertical pipe segment 2211 and an arc pipe segment 2212 which are sequentially communicated from top to bottom, one end of the arc pipe segment 2212 far away from the vertical pipe segment 2211 is inclined downward and is communicated with the interior of the tank body 100, further, the bendable piece 222 is slidably disposed in the guide channel, the bendable piece 222 includes a limiting film sleeve 2221 and round rods 2222, the round rods 2222 are arranged in parallel, adjacent round rods 2222 are in rolling fit, the limiting film sleeve 2221 is sealed and wrapped on the peripheries of the round rods 2222, so that the shape of the bendable piece 222 is matched with the interior space of the guide through pipe 221 and normally slides in the guide through pipe 221, and the driving assembly 210 is connected with the bendable piece 222 and is used for driving the bendable piece 222 to slide in the guide through pipe 221.

Illustratively, two guide side grooves 130 are respectively formed on two opposite inner side walls of the tank body 100, the single guide side groove 130 extends obliquely downwards and the topmost end of the guide side groove is communicated with the lower pipe orifice of the arc pipe segment 2212, further, the lowest ends of the two guide side grooves 130 on the same inner side wall of the tank body 100 are communicated and form a V shape, further, in the tank body 100, the upper area of the two guide side grooves 130 positioned in the V shape is configured as an upper stirring area 110, and the lower area of the two guide side grooves 130 positioned in the V shape is configured as a lower fermentation area 120.

Illustratively, the stop film cover 2221 is configured to be made of silicone, and when the two sets of flexible members 222 slide from the guide tube 221 to the lowest end of the guide side groove 130 under the action of the driving assembly 210, the stop film cover 2221 on the two sets of flexible members 222 tightly abuts to seal the upper stirring zone 110 and the lower fermentation zone 120 from each other.

On this basis, the partition assembly 220 mainly includes guide through pipes 221 and bendable members 222, wherein the guide through pipes 221 are symmetrically disposed on two outer walls of the tank body 100, each guide through pipe 221 is composed of a vertical pipe segment 2211 and an arc pipe segment 2212, the distal end of the arc pipe segment 2212 is inclined downward and is communicated with the interior of the tank body 100, and the bendable members 222 can smoothly move along the path of the guide through pipes 221 and finally enter the interior of the tank body 100 through the structural design. The bendable piece 222 is formed by arranging a plurality of round rods 2222 in parallel and then sealing and coating the round rods 2222 in the limiting membrane sleeve 2221, and the adjacent round rods 2222 are combined in a rolling and attaching mode, so that the round rods can be bent along with the change of a moving path.

Meanwhile, the driving assembly 210 is connected to the bendable member 222, and is capable of driving the bendable member 222 to slide along the guiding tube 221, and when the bendable member 222 moves vertically downward, it will sequentially move along the directions of the vertical tube segment 2211 and the arc tube segment 2212, and finally enter the tank 100. The inner wall of the can body 100 is provided with guide side grooves 130 in a V shape, a single guide side groove 130 extends obliquely downward, the topmost end is communicated with the outlet of the arc-shaped pipe segment 2212, and two guide side grooves 130 on the same side wall are communicated with each other at the lowest end, so that a V-shaped structure is formed. After entering the can body 100, the bendable members 222 further slide along the guiding side grooves 130 and gradually converge toward the V-shaped bottom until the two groups of bendable members 222 abut at the junction of the V-shaped bottom. Because limiting membrane cover 2221 is made of silica gel, has certain flexibility and elasticity, consequently when two sets of piece 222 that can buckle in V-arrangement bottom looks butt, can closely laminate between the limiting membrane cover 2221 to play sealed effect to a certain extent, make last stirring region 110 and lower fermentation region 120 form independent space relatively, in order to avoid the interference to the fermentation environment in the stirring process.

On the other hand, when it is desired to communicate the upper stirring zone 110 with the lower fermentation zone 120, the driving assembly 210 may be activated again, so that the bendable members 222 sequentially slide upward from the V-shaped bottom along the guide side grooves 130, and return to the vertical tube segment 2211 through the arc tube segment 2212, and finally exit the interior of the tank 100. In this way, the flexible partition and communication operation between the upper stirring zone 110 and the lower fermentation zone 120 can be flexibly performed by the movement of the flexible piece 222, which helps to improve the operation efficiency of the whole fermentation device. Compared with the traditional mechanical valve structure, the design adopts the combination of the bendable piece 222 and the limiting membrane sleeve 2221, so that the sealing effect is more uniform, and meanwhile, the problems of blockage or poor sealing possibly caused by a rigid structure are avoided. In addition, since the bendable piece 222 is composed of a plurality of round rods 2222, and the limiting membrane sleeve 2221 is coated outside, the limiting membrane sleeve is smoother in the moving process, and can adapt to the curve shapes of the guiding through pipe 221 and the guiding side groove 130, the service life and the stability of the partition assembly 220 can be improved, and excessive space is not occupied. Therefore, the design of the partition assembly 220 not only can effectively separate the upper stirring area 110 from the lower fermentation area 120, but also can enable the communication process to be more stable, reduce energy consumption and improve the overall automation level of the device.

In some embodiments, referring to fig. 2 and 3, the driving assembly 210 includes a multi-stage cylinder 211, a top plate 212, and a connecting rod 213, wherein the multi-stage cylinder 211 is installed at the top of the can 100 and is disposed in a vertical direction such that a piston rod thereof can extend and retract in an up-down direction. The top end of a piston rod of the multistage cylinder 211 is connected with the top plate 212, the top plate 212 is horizontally arranged and is vertically and fixedly connected with the piston rod at the center, so that the overall stability is enhanced to a certain extent, and the problem of deflection caused by single-point stress is avoided. The connecting rods 213 are mounted at both ends of the top plate 212 and are arranged in a vertical direction, and the lower end of each connecting rod 213 is connected to the middle of the top end of the corresponding bendable member 222, and this symmetrical connection manner helps to ensure the synchronism and balance of the bendable member 222 during movement. When the piston rod of the multistage cylinder 211 is contracted downwards, the top plate 212 moves downwards, the connecting rod 213 drives the bendable piece 222 to move downwards along the guide through pipe 221 to enter the tank body 100 until the bendable piece 222 is abutted to the bottom of the V-shaped guide side groove 130, and therefore the separation of the upper stirring area 110 and the lower fermentation area 120 is completed. According to the embodiment, through the hierarchical telescopic design of the multistage air cylinder 211, the movement of the bendable piece 222 is more stable, the problem of impact or clamping stagnation possibly caused by too fast movement is avoided, meanwhile, the power of the air cylinder can be uniformly transmitted to the bendable piece 222 through the arrangement of the connecting rod 213, the reliability and coordination of a driving process are improved, and the operation efficiency of the whole fermentation device is optimized.

The water pump 412 is installed on the outer wall of the first water storage tank 411, and the pumping-in end of the water pump 412 is communicated with the inside of the first water storage tank 411 through a pipe body, and one end of the transmission pipe 413 is communicated with the pumping-out end of the water pump 412, so that the water pump 412 can drive water flow along the transmission pipe 413 after being started. The other end of the transfer pipe 413 is communicated with the second water storage tank 414 after passing through the lower fermentation region 120 of the tank body 100, forming a complete fluid path. Illustratively, the portion of the transfer tube 413 located within the lower fermentation zone 120 is in the form of a wave.

In this way, if the temperature of the lower fermentation area 120 needs to be reduced in the heat exchange process, cold water is added into the first water storage tank 411, after the water pump 412 is started, the cold water is conveyed to the conveying pipe 413, and exchanges heat with surrounding organic water-soluble fertilizer when flowing through the lower fermentation area 120, absorbs part of heat of the cold water to gradually reduce the temperature of the lower fermentation area 120, and conversely, if the temperature needs to be increased, hot water can be filled into the first water storage tank 411 to realize temperature increase in the same way. It is worth noting that the pipe section of the transmission pipe 413 in the lower fermentation area 120 is in a wavy shape, i.e. the pipe section is not laid in a straight line, but adopts a wavy structure, so that the contact area between the heat exchange pipe and the organic water-soluble fertilizer can be increased, and the heat exchange efficiency can be improved. In addition, the wave-like structure can delay the water flow speed to a certain extent, so that the residence time of cold water or hot water in the transmission pipe 413 is increased, and the heat exchange effect is further improved. The heat exchange assembly 410 of this embodiment is designed through reasonable water circulation, so that the temperature adjustment is more stable, and meanwhile, the heat exchange efficiency is improved, so that the temperature of the lower fermentation area 120 is easier to control, and a more suitable environment is provided for the fermentation of the organic water-soluble fertilizer.

In some embodiments, referring to fig. 1 and 2, the oxygen supply assembly 420 includes a blower 421 and an air delivery pipe 422, where the air delivery pipe 422 is connected to a blower port of the blower 421. Illustratively, a mounting compartment is disposed at the opening of the upper end of the first water storage tank 411, the blower 421 is mounted in the mounting compartment, and the air-conveying pipe 422 is communicated with the secondary channel 4132 in the first water storage tank 411 after penetrating through the inner wall of the mounting compartment in a sealing manner, so that the wind power generated by the blower 421 can directly act on the secondary channel through the air-conveying pipe 422 and does not interfere with the conveying of the water by the conveying pipe 413.

The transmission pipe 413 is provided with a main channel 4131 and a secondary channel 4132 which are mutually independent along the self extending direction, the main channel 4131 is communicated with the pump outlet of the water pump 412, the secondary channel 4132 is communicated with the air transmission pipe 422, and the transmission pipe 413 is provided with a plurality of air outlet holes 4133 which are communicated with the secondary channel 4132 at intervals.

As illustrated in fig. 2,4 and 5, the on-off switching assembly 500 is provided with a plurality of on-off switching assemblies 500, one on-off switching assembly 500 corresponding to each of the air outlet holes 4133, along the pipe section portion of the transfer pipe 413 located in the lower fermentation area 120. It should be noted that the on-off switching assemblies 500 are all disposed on the linear pipe section of the transmission pipe 413, rather than the curved pipe section.

On the basis of this, in the construction of the oxygen supply path, the transfer tube 413 is divided into two mutually independent passages, namely a main passage 4131 and a sub-passage 4132, in the direction of its own extension. The main channel 4131 is mainly used for transferring heat exchange water flow between the first water storage tank 411 and the second water storage tank 414, and the sub channel 4132 is used as an air conveying channel and is communicated with the air conveying pipe 422 of the blower 421. Since the pipe structure of the transfer pipe 413 penetrates the lower fermentation region 120, the sub-passage 4132 is provided with a plurality of air outlet holes 4133 communicating with the sub-passage 4132 at intervals along the extending direction thereof, so that the air supplied from the blower 421 can uniformly enter the lower fermentation region 120 through the air outlet holes 4133, thereby optimizing the distribution of oxygen in the lower fermentation region 120.

Illustratively, the air outlet 4133 is disposed at the lower end surface of the transmission tube 413, so as to effectively prevent the organic water-soluble fertilizer from entering the transmission tube 413.

Through this kind of structural design, this embodiment can carry out the oxygen suppliment in step in the heat transfer process, realizes the collaborative optimization of heat transfer and oxygen suppliment. When the activity of the microorganism is affected by the temperature change during the fermentation process, the heat exchange component 410 can dynamically adjust the temperature, and the oxygen supply component 420 can ensure the continuous supply of oxygen, especially for the local anaerobic area easily formed in the fermentation material, the air outlet holes 4133 distributed at intervals can enable the oxygen to enter from different positions, so as to solve the problem of unbalanced oxygen distribution. In addition, the wind power delivery system of the oxygen supply assembly 420 does not interfere with the heat exchange water flow, and the blower 421 can independently operate to continuously supply oxygen to the lower fermentation area 120 even when the water pump 412 is operated to deliver cold water or hot water. The design not only improves the efficiency of heat exchange and oxygen supply, but also reduces the possibility of interference of the internal pipelines of the system, so that the whole structure is more compact and reasonable, and the device is suitable for application scenes with higher requirements on temperature and oxygen environment in the fermentation process of the organic water-soluble fertilizer.

In some embodiments, referring to fig. 2, 4 and 5, the switching on/off mechanism 500 includes a pressing assembly 600 and a shielding assembly 700, where the pressing assembly 600 is disposed in the transmission pipe 413 and between the main channel 4131 and the sub channel 4132, the shielding assembly 700 is slidably disposed in the sub channel 4132, and the shielding assembly 700 seals and shields the air outlet hole 4133 in a natural state.

Illustratively, when the water pump 412 is activated to allow water to flow within the primary channel 4131, the squeeze assembly 600 applies a pushing force to the shutter assembly 700 under the force of water pressure to move the shutter assembly 700 to a position where the vent holes 4133 are in communication with the secondary channel 4132, and the switching mechanism 500 is in the first state, further, when the water pump 412 is turned off to allow no water to flow within the primary channel 4131, the squeeze assembly 600 automatically resets, and the shutter assembly 700 also automatically resets to a position where the vent holes 4133 are sealed and blocked.

On this basis, the extrusion assembly 600 is disposed inside the transmission pipe 413, specifically between the main channel 4131 and the auxiliary channel 4132, and mainly acts to apply a pushing force to the shielding assembly 700 in response to the pressure change of the water flow in the main channel 4131, so that the oxygen supply channel is opened or closed at an appropriate time. The shielding assembly 700 is slidably mounted in the secondary channel 4132, and in a natural state, i.e., when no external force is applied, the shielding assembly 700 maintains a default position, so that the air outlet 4133 is sealed and shielded, preventing air from entering the lower fermentation area 120, and preventing organic water-soluble fertilizer in the lower fermentation area 120 from entering the secondary channel 4132.

When the water pump 412 is started, water flows in the main channel 4131, and a certain pressure is generated on the extrusion assembly 600 by the water flow, so that the extrusion assembly 600 moves towards the auxiliary channel 4132, and the shielding assembly 700 is pushed, so that the air outlet holes 4133 are exposed, the auxiliary channel 4132 is communicated with the outside, at this time, air conveyed by the air blower 421 can smoothly enter the auxiliary channel 4132 through the air conveying pipe 422 and uniformly spread to the lower fermentation area 120 through the air outlet holes 4133, and oxygen is supplied to the fermentation material. At this time, the switching on/off mechanism 500 is in the first state, i.e., the oxygen supply passage is opened.

When the water pump 412 is turned off, the water flow in the main passage 4131 is stopped, the water pressure is reduced, and the squeeze assembly 600 is automatically reset by losing the pressure. At the same time, the shielding assembly 700 returns to the original position under the action of self elastic force or gravity to seal and shield the air outlet 4133 again, so that the oxygen supply channel is disconnected from the outside, and the air conveyed by the blower 421 cannot enter the lower fermentation area 120. At this time, the switching on/off mechanism 500 is in the second state, i.e., the oxygen supply passage is closed.

Through the above structural design, this embodiment automatically opens the oxygen suppliment when water pump 412 works, and the oxygen suppliment is closed automatically after water pump 412 stops, need not extra control system to intervene, has realized an intelligent oxygen suppliment mode based on fluid pressure self-adaptation regulation. The oxygen supply mode can synchronously supply oxygen under the condition of high heat exchange requirement, optimize the growth environment of microorganisms, promote the fermentation efficiency and avoid unnecessary waste of air when oxygen supply is not needed. In addition, because the extrusion assembly 600 and the shielding assembly 700 are both arranged inside the transmission pipe 413, the whole mechanism is compact in structure and small in occupied space, the whole layout of the equipment is not greatly influenced, and the device is suitable for various fermentation process requirements.

In some embodiments, referring to fig. 2, 4 and 5, the pressing assembly 600 includes a pressing plate 610, a torsion spring 620, an elastic air bag 630, a limiting frame 640 and a guide frame 650, where the elastic air bag 630 is in an inflated state, and includes a hard air bag body 631, a first elastic air bag body 632 and a second elastic air bag body 633, the first elastic air bag body 632 is communicated with the upper end of the hard air bag body 631, the second elastic air bag body 633 is communicated with one side of the hard air bag body 631, the elasticity of the first elastic air bag body 632 is smaller than that of the second elastic air bag body 633, an opening is formed in the inner wall of the transmission tube 413 between the main channel 4131 and the auxiliary channel 4132 in a penetrating manner, the opening is covered with an elastic sealing film 800 in a sealing manner, the first elastic air bag body 632 is inflated upward, and then the elastic sealing film 800 is jacked up, so that the elastic sealing film 800 forms a raised portion in the main channel 4131, and the second elastic air bag body 633 is raised along the extending direction of the auxiliary channel 4132.

The extruding plate 610 is hinged on the inner wall of the main channel 4131 near the sub channel 4132 by a torsion spring 620, the extruding plate 610 is inclined towards the direction of the water flow path when in a natural state under the action of the torsion spring 620, and the extruding plate 610 is abutted against the elastic sealing film 800, further, a limiting frame 640 is arranged in the sub channel 4132, the hard capsule 631 is connected to the limiting frame 640, and a guide frame 650 is arranged on the limiting frame 640 and is positioned on the periphery of the second elastic capsule 633, so that the second elastic capsule 633 expands along the length direction of the sub channel 4132 when expanding. Illustratively, when the water pump 412 is activated to allow water to flow within the primary passageway 4131, the squeeze plate 610 is hydraulically biased downwardly against the first resilient bladder 632 to collapse the first resilient bladder 632 and simultaneously urge the second resilient bladder 633 to expand in the direction of extension of the secondary passageway 4132.

In some embodiments, referring to fig. 2,4 and 5, the shielding assembly 700 includes a positioning plate 710, a spring 720, a sliding column 730 and a guide block 740, wherein the sliding column 730 is slidably disposed in the auxiliary channel 4132 along the extending direction of the auxiliary channel 4132 and is located at one side of the second elastic bag body 633, the guide block 740 is disposed on the surface of the sliding column 730, two ends of the sliding column 730 are sealed and are arranged in a hollow manner, the side surface of the sliding column 730 is provided with an air inlet 731 in a penetrating manner, so that air in the auxiliary channel 4132 enters the sliding column 730 through the air inlet 731, the lower wall of the sliding column 730 is provided with an air outlet 732 in a penetrating manner, and the air outlet 732 can be radially opposite to the air outlet 4133 when the sliding column 730 moves along the length direction of the auxiliary channel 4132.

The auxiliary channel 4132 is provided with guide grooves 4134 in parallel on an inner wall thereof, which is close to the main channel 4131, and the guide block 740 is slidably inserted into the guide grooves 4134, and further, the positioning plate 710 is fixedly arranged in the auxiliary channel 4132 at a position of the sliding column 730, which is away from the second elastic bag 633, the spring 720 is connected between the positioning plate 710 and an end portion of the positioning column, and the spring 720 always has a position of pushing the sliding column 730 to stagger the air outlet 732 and the air outlet 4133. Further, when the water pump 412 is activated to allow water to flow in the main channel 4131, the second elastic bladder 633 expands along the extending direction of the sub channel 4132 and pushes the sliding column 730 to move to a position where the air outlet 732 is radially opposite to the air outlet 4133.

On this basis, first, when the water pump 412 is started, the water flow in the main channel 4131 pushes the squeeze plate 610 to incline, so that the squeeze plate 610 deflects downward around the hinge point, and applies pressure to the elastic sealing membrane 800 to press it downward, thereby contracting the first elastic bladder 632. Since the first elastic balloon 632 communicates with the second elastic balloon 633 and the hard balloon 631 is in a stable state without deformation, when the first elastic balloon 632 is compressed, the gas inside thereof is forced to flow toward the second elastic balloon 633 so that the second elastic balloon 633 expands in the length direction of the sub-channel 4132. Because of the existence of the limiting frame 640 and the guide frame 650, the expansion direction of the second elastic bag body 633 is limited, and the second elastic bag body can only extend along the direction of the secondary channel 4132, so that the situation of uneven expansion or abnormal deformation is avoided, and the sliding column 730 in the shielding assembly 700 can be reliably pushed to move along the secondary channel 4132, so that the air flow outlet 732 is opposite to the air outlet hole 4133, and the oxygen supply channel is opened. At this time, the air flow conveyed by the blower 421 may enter the sub-channel 4132 along the air conveying pipe 422, and sequentially pass through the air flow inlet 731, the inner cavity of the sliding column 730, the air flow outlet 732 and the air outlet 4133, and finally enter the lower fermentation area 120, so that the organic water-soluble fertilizer is fully supplied with oxygen, which is helpful for promoting the activity of aerobic microorganisms, improving the fermentation efficiency, and reducing the possibility of forming anaerobic environment.

On the other hand, when the water pump 412 stops operating, the water flow in the main passage 4131 disappears, the pressing plate 610 loses the water flow pushing force, and gradually returns to the original inclined state by the torsion spring 620. Meanwhile, since one end of the sliding column 730 is biased by the spring 720, the sliding column 730 moves back toward the initial direction, so that the air outlet 732 is staggered from the air outlet 4133, the connection between the sub-channel 4132 and the lower fermentation area 120 is cut off, the oxygen supply process is stopped, and then the sliding column 730 pushes the second elastic bag body 633 to compress, and at this time, the first elastic bag body 632 re-expands to jack up the elastic sealing film 800, so that the extrusion plate 610 is re-reset to the initial inclined state under the dual pushing action of the first elastic bag body 632 and the torsion spring 620. The design mode can keep linkage between the oxygen supply process and the water flow heat exchange process, so that the problem that water flow and air supply are carried out simultaneously or are mutually interfered is avoided, and the stability and the adaptability of the system operation are improved.

It should be noted that, in the above structure, the elasticity of the first elastic bag body 632 is smaller than that of the second elastic bag body 633, and this design helps to compress the first elastic bag body 632 preferentially when the water flow starts, so that the air flow is regulated more accurately, and the resetting effect is better when the water flow stops running. Further, both ends of the sliding column 730 are sealed and the inside is a cavity, and a gas flow inlet 731 is provided at the side so that gas can smoothly enter the inside of the sub-channel 4132, and the opening and closing of the gas flow channel is controlled by precise position adjustment. In addition, the guide block 740 of the sliding column 730 is matched with the guide groove 4134 on the inner wall of the sub-channel 4132, so that the sliding column 730 can slide along the set direction, and the problems of inclination, clamping stagnation or position deviation are avoided, thereby improving the reliability of the switching on-off mechanism 500.

Illustratively, the width of the secondary channel 4132 is greater than the maximum thickness of the resilient bladder 630, and at the same time, 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, such that the resilient bladder 630, the sliding column 730 and the positioning plate 710 are not easily completely shielded from the flow of air within the secondary channel 4132 when the air flows, so that the air can normally flow within the secondary channel 4132. Further, the end of the secondary channel 4132 remote from the air delivery pipe 422 is sealed, i.e. the secondary channel 4132 does not extend through the entire delivery pipe 413, so that the air flowing in the secondary channel 4132 can only flow from the air outlet 4133 into the lower fermentation area 120.

In a comprehensive view, the embodiment realizes the automatic control of the oxygen supply process in the water flow heat exchange process, so that the fermentation environment of the organic water-soluble fertilizer can automatically supplement oxygen when the heat exchange requirement is high, the uniformity of fermentation is improved, the activity of aerobic microorganisms is enhanced, and the adverse effect of the anaerobic environment is reduced. Meanwhile, the oxygen supply assembly 420 and the water flow heat exchange process have self-adaptive adjustment capability, so that unnecessary gas waste is avoided, and the energy utilization rate is improved. The design structure of the embodiment is compact, the occupied space is small, the device can be suitable for fermentation equipment of different types, and the device has high practical value in practical application.

The foregoing is merely illustrative embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily think about variations or substitutions within the technical scope of the present invention, and the invention should be covered.
