Description

Technical Field

[0001] The present application relates to the technical field of the fermentation preparation of biological fertilizers, and particularly relates to a device and process for the fermentation preparation of biological fertilizers. Background Art

[0002] Biological fertilizers play an extremely important role in agricultural production. They can effectively improve soil quality and promote crop growth. The development of microbial fermentation technology has provided new possibilities for the preparation of biological fertilizers. Through specific culture conditions and the selection of microbial strains, reacting with waste materials (such as straws, animal feces, etc.) can produce a large amount of biological fertilizers in a relatively short time, which not only improves the effectiveness of fertilizers, but also significantly enhances their stability and application scope.

[0003] In order to facilitate the full contact between straws and microorganisms, the straws are often crushed before the reaction. For example, the patent application with the publication number CN116655414A discloses a device for preparing fermented fertilizers from waste straws, which mainly consists of a bottom plate, a crushing box and a fermentation box. A feeding port is provided at the top of the crushing box and is equipped with a two-stage pretreatment mechanism: the upper crushing component initially crushes the straws, and the lower flattening component further flattens the crushed materials through a dividing inclined plate to increase the contact area of the materials and shorten the subsequent fermentation cycle. This device significantly improves the straw decomposition efficiency through combined crushing-flattening pretreatment.

[0004] However, there are still the following problems when using the above prior art to crush straws: the above prior art can perform roller-type crushing treatment on straws. Although it can flatten and crush them, it does not completely destroy the fiber bundle structure of the straws, resulting in the interior of the straws not being fully exposed to the outside, affecting the subsequent contact area between the straws and microorganisms, and thus affecting the preparation rate of biological fertilizers.

[0031] The following further elaborates on the present application in conjunction with the attached drawings Figures 1 to 7 .

[0032] The embodiment of the present application discloses a device and process for the preparation of biological fertilizer by fermentation. During the straw treatment process, the straw can be stripped into multiple structures, thereby completely destroying the fiber bundle structure of the straw, exposing the inside of the straw to the outside, increasing the contact area between the straw and the microbial strains, and thus improving the preparation rate of biological fertilizer

[0033] Embodiment 1: Referring to Figure 1 and Figure 2 , a device for the preparation of biological fertilizer by fermentation includes a processing frame 1 with an upward - opening and U - shaped structure. A conveying mechanism 2 is jointly installed on the two vertical sections of the processing frame 1, and a crushing mechanism 3 is installed inside the processing frame 1. Among them, the crushing mechanism 3 includes: Rotating shafts 31, symmetrically arranged along the depth direction of the processing frame 1, and a rubber belt 32 is jointly installed between the two rotating shafts 31

[0034] Both ends of the rotating shaft 31 are provided with fixed frames 33, and the rotating shaft 31 is installed on the fixed frames 33 through bearings

[0035] There are multiple groups of peeling rods 34 evenly arranged along the width direction of the rubber belt 32. Each group of peeling rods 34 is evenly provided with a plurality of peeling rods 34 along the length direction of the rubber belt 32, and is used for peeling the straw.

[0036] During the movement of the peeling rods 34, the straw can be peeled. And every time it peels once, the straw rotates by a certain angle. Thus, during the process of processing the straw, the peeling rods 34 can peel the straw into multiple strips, and the peeling rods 34 can completely destroy the fiber bundle structure of the straw, making the inside of the straw exposed to the outside, increasing the contact area between the straw and the microbial strains, and thereby improving the preparation rate of the biological fertilizer.

[0037] Refer to Figure 3 and Figure 4 , the conveying mechanism 2 includes: There are two support frames 21, which are respectively installed on the two vertical sections of the processing frame 1. A conveying frame 22 is jointly installed between the two support frames 21.

[0038] At the four corners of the bottom of the conveying frame 22, conveying rollers 23 are installed through bearings. A conveyor belt 24 for conveying the straw is jointly installed between two adjacent conveying rollers 23 along the length direction of the conveying frame 22.

[0039] Two groups of extrusion shafts 25 are symmetrically installed at the bottom of the conveying frame 22 along its width direction, and the extrusion shafts 25 are evenly distributed along the length direction of the conveying frame 22, and are used for extruding and limiting the conveyor belt 24.

[0040] Among them, the peeling rods 34 and the rubber belt 32 are located below any group of conveying rollers 23, and the end of the peeling rods 34 close to the gap between the two conveyor belts 24 coincides exactly with the gap between the two conveyor belts 24, so as to ensure that the peeling rods 34 can peel the straw between the two conveyor belts 24 during the movement process. Specifically, during operation, the conveying roller 23 on the side close to the peeling rods 34 is driven to rotate by an external driving force (such as a motor, not shown in the figure). During the rotation of the conveying roller 23, the conveyor belt 24 is driven to move. At this time, the straw is sequentially placed between the two conveyor belts 24. The moving conveyor belt 24 and the stationary conveyor belt 24 cooperate with each other to drive the straw to intermittently move into the processing frame 1. That is, every time the straw moves a certain distance into the processing frame 1, the moving conveyor belt 24 stops for a while to ensure that the peeling rods 34 can fully peel the straw.

[0041] During the time when the moving conveyor belt 24 stops, the rotating shaft 31 is driven to rotate by an external driving force (such as a motor, not shown in the figure). During the rotation of the rotating shaft 31, the rubber belt 32 is driven to move. During the movement of the rubber belt 32, the peeling rods 34 are driven to move along the depth direction of the processing frame 1. Thus, the peeling rods 34 can peel the straw, making the straw peeled into a strip structure.

[0042] It should be noted that the rubber belt 32 is divided into a stripping part and an empty return part. The stripping part is equipped with a stripping rod 34, while the empty return part is not equipped with a stripping rod 34. Moreover, every time the rotating shaft 31 drives the rubber belt 32 to move a certain distance, the stripping part of the rubber belt 32 is completely facing the straw or the empty return part of the rubber belt 32 is completely facing the straw.

[0043] After the stripping rod 34 strips the straw once, the rotating shaft 31 rotates to drive the stripping part of the rubber belt 32 to leave the straw, and the empty return part of the rubber belt 32 faces the straw. At this time, the moving conveyor belt 24 continues to work and drives the straw to continue moving. Since the empty return part of the rubber belt 32 gives way, the straw will not collide with the stripping rod 34 during the movement. At this time, during the movement of the straw, the moving conveyor belt 24 and the stationary conveyor belt 24 cooperate with each other to drive the straw to rotate synchronously by a certain angle, and then the rotating shaft 31 continues to rotate to drive the stripping part of the rubber belt 32 to move to one side of the straw. During the movement of the rubber belt 32, the stripping rod 34 strips the straw.

[0044] By repeating the above actions, the moving straw can be stripped to make the straw strip-shaped. Therefore, the stripping rod 34 can completely destroy the fiber bundle structure of the straw, exposing the inside of the straw to the outside, increasing the contact area between the straw and the microbial strains, thereby improving the biofertilizer preparation rate.

[0045] The extrusion shaft 25 can exert an extrusion and limit effect on the conveyor belt 24 to ensure the friction between the conveyor belt 24 and the straw, thereby ensuring that the conveyor belt 24 will not easily fall off the conveyor belt 24 during the process of conveying the straw and the straw stripping process.

[0046] Reference Figure 4 In order to further ensure the straw conveying effect, a plurality of rubber strips 241 are evenly arranged on the conveyor belt 24 along its width direction, and the rubber strips 241 on the two conveyor belts 24 are staggered along the width direction of the conveyor belt 24 .

[0047] During specific operation, the conveyor belt 24 adopts an array of staggered rubber strips 241 to form a serrated meshing structure, which generates vertical restraint force and lateral friction force, so that the straw is in closer contact with the conveyor belt 24 when conveying the straw, further reducing the possibility of straw falling when conveying and stripping the straw.

[0048] Reference Figure 5 During the stripping process, the straw strip structure will be broken due to the large rigid pulling force of the stripping rod 34. The feeding belt 12 provided by the present invention can collect and transport the broken straw strip structure. Specifically, the processing frame 1 is provided with rotating shafts 11 symmetrically arranged along its length direction, and the feeding belts 12 are installed between the rotating shafts 11.

[0049] During specific operation, when stripping straw, an external drive (such as a motor, not shown in the figure) drives the rotating shaft 11 to rotate. During the rotation of the rotating shaft 11, the feeding belt 12 is driven to move. During the movement of the feeding belt 12, the broken straw can be collected and conveyed and collected outside the processing frame 1, avoiding the accumulation of straw caused by the broken straw falling to the bottom of the processing frame 1.

[0050] Refer to Figure 5 and Figure 6 , due to the fact that static electricity adsorption and mechanical entanglement occur to the straw fibers under the action of shear force during the stripping process, resulting in the fibers adhering to the surface of the stripping rod 34. The periodic movement of the reciprocating push plate 321 can achieve fiber stripping through the following mechanism. Specifically, a plurality of push plates 321 are uniformly arranged along the width direction of the rubber belt 32 on the side of the rubber belt 32 close to the vertical side wall of the processing frame 1, and the push plates 321 are located between adjacent groups of stripping rods 34 and can reciprocate along the length direction of the stripping rods 34.

[0051] A plurality of linkage rods 322 corresponding one-to-one to the push plates 321 are slidably arranged through the vertical section of the processing frame 1, and one end of the linkage rod 322 located inside the processing frame 1 is installed on the push plate 321. The other ends of the linkage rods 322 located outside the processing frame 1 are jointly installed with a linkage plate 323, and a telescopic spring rod 324 for resetting the linkage plate 323 is jointly installed between the linkage plate 323 and the vertical section of the processing frame 1.

[0052] A linkage straight rod 325 is installed on the rotating shaft 11 close to the rubber belt 32, and the linkage straight rod 325 is installed on the processing frame 1 through a bearing. A linkage connecting rod 326 is installed on the processing frame 1 through a bearing. A traction rope 327 is installed on the linkage connecting rod 326. One end of the traction rope 327 away from the linkage connecting rod 326 is installed on the linkage plate 323. An incomplete gear 328 is installed on the linkage straight rod 325, and a straight gear 329 meshing with the incomplete gear 328 is installed on the linkage connecting rod 326.

[0053] A first cylindrical rod flush with the linkage rod 322 is installed on the vertical section of the processing frame 1 where the linkage connecting rod 326 is installed. A first fixed pulley 13 is installed on the first cylindrical rod. A second cylindrical rod is arranged between the first cylindrical rod and the linkage connecting rod 326, and the second cylindrical rod is installed on the vertical section of the processing frame 1. A second fixed pulley 14 is installed on the second cylindrical rod. One end of the traction rope 327 away from the linkage plate 323 passes through the side of the first fixed pulley 13 away from the processing frame 1 and the side of the second fixed pulley 14 close to the processing frame 1 in sequence and is then installed on the linkage connecting rod 326.

[0054] During specific operation, when the corresponding rotating shaft 11 rotates, it drives the linkage straight rod 325 to rotate. During the rotation of the linkage straight rod 325, it drives the incomplete gear 328 and the spur gear 329 to mesh with each other, further driving the linkage connecting rod 326 to rotate. During the rotation of the linkage connecting rod 326, the traction rope 327 is wound. At this time, the traction rope 327 drives the linkage plate 323 to move away from the processing frame 1 through the cooperation of the first fixed pulley 13 and the second fixed pulley 14. At this time, the telescopic spring rod 324 is stretched. During the movement of the linkage plate 323, it drives the linkage rod 322 to move synchronously. During the movement of the linkage rod 322, it drives the pushing plate 321 to move. At this time, during the movement of the pushing plate 321, the straw fibers wound around the stripping rod 34 can be pushed out from the stripping rod 34 and fall on the feeding belt 12.

[0055] When the teeth on the incomplete gear 328 disengage from the spur gear 329, at this time, the traction rope 327 is no longer constrained by the linkage connecting rod 326. The telescopic spring rod 324 resets and drives the linkage plate 323 to reset. At this time, the linkage plate 323 drives the push rod to reset synchronously through the linkage rod 322, and the traction rope 327 resets synchronously at this time. Then, by repeating the above actions, the pushing plate 321 can be driven to move periodically in a reciprocating manner, achieving the purpose of separating the straw fibers from the stripping rod 34.

[0056] It should be noted that the cooperation of the first fixed pulley 13 and the second fixed pulley 14 can reverse the direction of the traction rope 327 to ensure that during the rotation of the linkage connecting rod 326, the traction rope 327 drives the linkage plate 323 to move away from the processing frame 1.

[0057] Embodiment 2: Looking back Figure 2 , on the basis of Embodiment 1, liquid inlet pipes 15 are installed through both vertical sections of the processing frame 1, and spray pipes 16 are installed on the opposite surfaces of the liquid inlet pipes 15.

[0058] The conveyor belt 24 can drive the stripped straw strips to rotate through its friction force, thereby generating a centrifugal force to spread the straw strips outward, increasing the space between the straw strips and making the internal structure of the straw more exposed. The cooperation of the liquid inlet pipe 15 and the spray pipe 16 precisely sprays the microbial strains into the exposed interior of the straw during the spreading process of the straw strips, ensuring sufficient and effective contact between the microbial strains and the straw strips, thereby significantly improving the reaction rate and efficiency between the straw and the microbial strains and achieving rapid and sufficient preparation of biological fertilizers.

[0059] Finally, the straw sprayed with microbial strains is collected and processed.

[0060] Finally, referring to Figure 7 , the present invention also provides a biological fertilizer fermentation preparation process, and its preparation process includes the following steps: S1: Feeding preparation. Drive the conveying roller 23 near the stripping rod 34 to rotate through an external driving force. During the rotation of the conveying roller 23, the conveyor belt 24 is driven to move. At this time, the straw is sequentially placed between the two conveyor belts 24. The moving conveyor belt 24 and the stationary conveyor belt 24 cooperate with each other to drive the straw to intermittently move into the processing frame 1. That is, whenever the straw moves a certain distance into the processing frame 1, the moving conveyor belt 24 stops for a while.

[0061] S2: Stripping treatment. During the period when the moving conveyor belt 24 stops, drive the rotating shaft 31 to rotate through an external driving force. During the rotation of the rotating shaft 31, the rubber belt 32 is driven to move. During the movement of the rubber belt 32, the stripping rod 34 is driven to move along the depth direction of the processing frame 1. Furthermore, the stripping rod 34 can perform stripping treatment on the straw, so that the straw is stripped into a strip structure.

[0062] S3: Spraying treatment. Spray microbial strains on the stripped straw.

[0063] S4: Collection treatment. Collect and treat the straw sprayed with microbial strains.
