Description

Technical Field

[0001] The invention relates to the technical field of strain reaction, and in particular to a reaction device for composite microbial fertilizer strains. Background Art

[0002] In the production of compound microbial fertilizers, microbial strains (such as nitrogen-fixing bacteria, phosphate-solubilizing bacteria, Bacillus subtilis, etc.) need to achieve proliferation and accumulation of metabolically active substances through the fermentation process. Agitation is one of the core operations in the fermentation process. Its role is far more than simple mixing, but it directly affects bacterial growth, nutrient utilization, mass transfer efficiency and final product performance.

[0003] A variety of auxiliary materials (such as carbon sources, nitrogen sources, inorganic salts, etc.) are often added during the reaction process. These substances have different densities and solubilities and are easily stratified due to gravity. Manual mixing is often performed in existing reaction devices. However, manual mixing is inefficient and insufficient, which can easily lead to uneven temperatures and contamination by foreign bacteria, thereby affecting the stirring effect of the reactants, resulting in slow bacterial growth and insufficient metabolic products. Summary of the invention

[0004] In view of the above-mentioned shortcomings of the prior art, the present invention provides a reaction device for a composite microbial fertilizer strain, which can effectively solve the problem of how to improve the reaction rate in the prior art.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0006] The present invention provides a reaction device for composite microbial fertilizer strains, comprising a reactor, a reactor cover and a driving motor, wherein the reactor cover is installed on the top of the reactor and is used to seal the top of the reactor, the driving motor is installed on the bottom of the reactor, and the output end of the driving motor is transmission-connected with a stirring component, and the stirring component is used to stir the strain mixture in the reactor;

[0007] The stirring assembly includes a separation cylinder fixedly installed on the inner wall of the bottom of the reactor and a transmission shaft fixedly connected to the output end of the driving motor. The transmission shaft is equipped with downward pressure blades and multiple stirring racks from bottom to top. When the downward pressure blades rotate, the mixed liquid is pushed to the bottom of the reactor. The stirring rack has multiple stirring rods. The downward pressure blades and the stirring rack are both located in the separation cylinder. The bottom of the separation cylinder is provided with multiple outflow grooves for the flow of the strain mixture.

[0008] Furthermore, a hydraulic push rod is fixedly connected to the top of the kettle cover, and an output end of the hydraulic push rod passes through the kettle cover and extends into the reactor. The output end of the hydraulic push rod is movably connected to a mixing assembly, which is used to accommodate auxiliary materials such as carbon sources, nitrogen sources, and inorganic salts.

[0009] Further, the mixing assembly includes a lower supporting box vertically and slidably installed in the reaction kettle. The lower supporting box corresponds to the space between the partition cylinder and the reaction kettle. The top of the lower supporting box is rotatably connected to an upper supporting box. The upper supporting box is movably connected to the output end of the hydraulic push rod. The bottom of the upper supporting box is fixedly connected with a plug rod. The plug rod is slidably inserted into the transmission shaft. The upper supporting box is provided with a plurality of slots for pouring auxiliary materials. The bottom of the top plate of the upper supporting box is fixedly connected with a plurality of stirring plates. During the rotation of the upper supporting box, the stirring plates stir the auxiliary materials in the lower supporting box and the upper supporting box. The bottom of the lower supporting box is provided with a plurality of through holes for the auxiliary materials to fall.

[0010] Further, a rotating disk is rotatably connected to the bottom plate of the lower supporting box. The rotating disk is provided with a plurality of through slots. A plurality of baffle plates are rotatably connected to the rotating disk. The bottom of the rotating disk is fixedly connected with a plurality of limiting plates corresponding to the positions of the baffle plates. The limiting plates are used to limit the rotation direction of the baffle plates. The top of the rotating disk is fixedly connected with a plurality of pushing plates in contact with the stirring plates.

[0011] Further, the through slots and the baffle plates are closely and spacedly distributed. The bottom of the lower supporting box is fixedly connected with a plurality of conical cylinders corresponding to the positions of the through holes. The large openings of the conical cylinders face downward to help more mixed liquid enter.

[0012] Further, a sleeve is slidably sleeved on the top of the partition cylinder. A spring is fixedly connected between the partition cylinder and the sleeve.

[0013] Further, a slide bar is fixedly installed on the outer wall of the transmission shaft. Limit blocks for restricting the positions of the stirring frames are installed at both ends of the slide bar. A plurality of the stirring frames are slidably installed on the transmission shaft through the slide bar, and springs are fixedly connected between the stirring frames.

[0014] Further, a rotating seat is rotatably connected to the center of the top of the upper supporting box. Two fixing blocks are symmetrically and fixedly connected to the top of the rotating seat. A clamping block is elastically and slidably connected in the fixing block through a spring. A clamping groove corresponding to the clamping block is provided at the output end of the hydraulic push rod.

[0015] The technical solution provided by the present invention has the following beneficial effects compared with the known public technologies:

[0016] (1) By adopting the cooperation between the stirring assembly and the mixing assembly, the present invention can help mix the auxiliary materials and gradually release the auxiliary materials. When the auxiliary materials are fully mixed and there is a remainder, the auxiliary materials are completely released. At the same time, the stirring assembly and the mixing assembly carry out stirring work simultaneously, so that the auxiliary materials are quickly mixed in the mixed liquid, effectively improving the stirring efficiency;

[0017] (2) By adopting a stirring component, a bottom-up flow of the mixed liquid is formed in the reaction kettle. After the mixed liquid flows to the highest point, it impacts on the stirring blades. By utilizing the rotation of the stirring blades themselves and the impact generated by the fall of the mixed liquid itself, the mixed liquid can be fully diffused, enhancing the stirring effect on the mixed liquid and accelerating the mixing speed.

[0018] (3) By adopting a mixing component, during the mixing process of the mixed liquid, partial release and mixing of the auxiliary materials are carried out synchronously. At the same time, the auxiliary materials are released into the flowing mixed liquid, and when they flow back above the stirring blades along with the mixed liquid, they are fully mixed with the mixed liquid, thereby helping to enhance the stirring effect and improve the mixing efficiency.

Detailed implementation manners

[0032] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0033] The present invention will be further described below with reference to the embodiments.

[0034] Embodiment: Refer to Figures 1 to 11 , a reaction device for a composite microbial fertilizer strain, including a reaction kettle 1, a kettle cover 2 and a drive motor 3. The kettle cover 2 is installed on the top of the reaction kettle 1 to seal the top of the reaction kettle 1. The drive motor 3 is installed at the bottom of the reaction kettle 1. The output end of the drive motor 3 is in transmission connection with a stirring assembly 4, and the stirring assembly 4 is used for stirring the strain mixture in the reaction kettle 1;

[0035] This application adopts a stirring assembly 4, which can help the reactants flow and accelerate the mixing speed. The stirring assembly 4 includes a partition cylinder 405 fixedly installed on the inner wall of the bottom of the reaction kettle 1 and a transmission shaft 401 fixedly connected to the output end of the drive motor 3. The transmission shaft 401 is provided with a downward pressing fan blade 402 and a plurality of stirring frames 403 from bottom to top. When the downward pressing fan blade 402 rotates, it pushes the mixture towards the bottom of the reaction kettle 1. The stirring frame 403 has a plurality of stirring rods. The downward pressing fan blade 402 and the stirring frame 403 are both located in the partition cylinder 405. The bottom of the partition cylinder 405 is provided with a plurality of outflow grooves 407 for the strain mixture to flow through.

[0036] During the process of mixing the mixed solution of the mixed strains, the operation of the driving motor 3 will drive the downward pressing fan blade 402 and the stirring frame 403 to rotate together. During the rotation of the downward pressing fan blade 402, through the pushing action of the inclined plane, the mixed solution is pushed to the bottom of the reaction kettle 1, and flows through the outflow groove 407 at the bottom of the partition cylinder 405 to the position between the reaction kettle 1 and the partition cylinder 405. Then, this part of the mixed solution moves upward and flows back into the partition cylinder 405. When the mixed solution flows back into the partition cylinder 405, the rotating stirring frame 403 will help stir the flowing-back mixed solution. In this way, the mixed solution will flow upward and downward, and when the mixed solution falls from above, it will also be stirred by the stirring frame 403, so that the mixed solution can impact on the stirring frame 403 at a certain speed under the action of gravity. The rotating stirring frame 403 will generate a certain impact on the mixed solution and at the same time help the mixed solution to splash in the reverse direction of rotation to increase the mixing degree, which can help improve the stirring efficiency, prevent the mixed solution from accumulating at the bottom of the reaction kettle 1, and utilize the flow of the mixed solution itself to help stir the mixed solution, thereby improving the stirring efficiency. The top of the kettle cover 2 is fixedly connected with a hydraulic push rod 6. The output end of the hydraulic push rod 6 passes through the kettle cover 2 and extends into the reaction kettle 1. The output end of the hydraulic push rod 6 is movably connected with a mixing component 5, and the mixing component 5 is used to accommodate auxiliary materials such as carbon source, nitrogen source, and inorganic salts.

[0037] Specifically, the mixing component 5 includes a lower supporting box 501 vertically and slidably installed in the reaction kettle 1. The lower supporting box 501 corresponds to the interval between the partition cylinder 405 and the reaction kettle 1. The top of the lower supporting box 501 is rotatably connected with an upper supporting box 502. The upper supporting box 502 is movably connected to the output end of the hydraulic push rod 6. The bottom of the upper supporting box 502 is fixedly connected with an insertion rod 503. The insertion rod 503 is slidably inserted into the transmission shaft 401. A plurality of slots for pouring auxiliary materials are opened on the upper supporting box 502. The bottom of the top plate of the upper supporting box 502 is fixedly connected with a plurality of stirring plates 504. During the rotation of the upper supporting box 502, the stirring plates 504 stir the auxiliary materials in the lower supporting box 501 and the upper supporting box 502. A plurality of through holes 505 for the auxiliary materials to fall are opened at the bottom of the lower supporting box 501.

[0038] Before stirring, auxiliary materials such as carbon source, nitrogen source, inorganic salt, etc. can be placed between the lower support box 501 and the upper support box 502, and then the kettle cover 2 is buckled on the reactor 1 to make the reactor 1 airtight. During the rotation of the transmission shaft 401, the upper support box 502 on the top of the lower support box 501 rotates together. Since the lower support box 501 can only slide vertically in the reactor 1, the rotation of the upper support box 502 cannot drive the lower support box 501 to rotate. In this process, the stirring plate 504 on the upper support box 502 performs a circular motion relative to the lower support box 501, and stirs the various auxiliary materials in the lower support box 501 and the upper support box 502. This part of the auxiliary materials is continuously stirred in the lower support box 501 and the upper support box 502 during the rotation of the upper support box 502. 02, and in this process, part of the auxiliary materials will fall down from the through hole 505. Since the position of the lower support box 501 is just above the gap between the separation cylinder 405 and the reactor 1, the auxiliary materials that fall down will directly fall into the stirred mixed liquid. In the process of the mixed liquid flowing from bottom to top, part of the auxiliary materials will flow back to the separation cylinder 405, and will be fully mixed under the stirring action of the stirring frame 403 and the downward pressure fan blade 402. The auxiliary materials are mixed in the mixed liquid in advance and in a small amount and quickly, avoiding the problem of auxiliary materials being easy to agglomerate due to pouring a large amount of auxiliary materials at one time. At the same time, the advance mixing of the auxiliary materials can reduce the time required for mixing in the mixed liquid, and the auxiliary materials released in small amounts can also be fully mixed in the flowing mixed liquid, helping to improve the mixing efficiency.

[0039] Specifically, a rotating disk 506 is rotatably connected to the bottom plate of the lower supporting box 501, and a plurality of through grooves 507 are opened on the rotating disk 506. A plurality of baffles 509 are rotatably connected to the rotating disk 506. A plurality of limit plates 514 are fixedly connected to the bottom of the rotating disk 506 corresponding to the position of the baffle 509. The limit plates 514 are used to limit the rotation direction of the baffle 509. A plurality of push plates 508 in contact with the stirring plate 504 are fixedly connected to the top of the rotating disk 506. The through grooves 507 and the baffles 509 are closely spaced. A plurality of conical cylinders 510 are fixedly connected to the bottom of the lower supporting box 501 corresponding to the position of the through hole 505. The large pipe openings of the conical cylinders 510 are distributed downward to help more mixed liquids enter.

[0040] During the rotation of the upper supporting box 502, through the contact between the stirring plate 504 and the pushing plate 508, it can help push the rotating disk 506 fixedly connected to the pushing plate 508 to rotate. During this process, the through groove 507 formed on the rotating disk 506 will continuously pass above the through hole 505. Only when the through groove 507 is above the through hole 505, the auxiliary materials can fall from the through hole 505 into the mixed liquid. When the through groove 507 is not above the through hole 505, the auxiliary materials will be continuously stirred under the rotation of the stirring plate 504, thereby helping to mix various auxiliary materials so that all kinds of auxiliary materials can be mixed to a certain extent before falling onto the mixed liquid, helping the mixed liquid to quickly blend various auxiliary materials.

[0041] Specifically, a sleeve 406 is slidably sleeved on the top of the partition cylinder 405. A spring is fixedly connected between the partition cylinder 405 and the sleeve 406. A slide bar 404 is fixedly installed on the outer wall of the transmission shaft 401, and limit blocks for restricting the position of the stirring frame 403 are installed at both ends of the slide bar 404. A plurality of the stirring frames 403 are slidably installed on the transmission shaft 401 through the slide bar 404, and springs are fixedly connected between the stirring frames 403.

[0042] After the upper supporting box 502 rotates for a certain period of time, the auxiliary materials are mixed in the lower supporting box 501 and the upper supporting box 502. The hydraulic push rod 6 at the top of the kettle lid 2 is activated to push the entire mixing assembly 5 downward. At this time, the downward-moving upper supporting box 502 will drive the lower supporting box 501 to move together. After the upper supporting box 502 moves down to a certain depth, it will press the sleeve 406 and the stirring frame 403, causing the sleeve 406 to move downward, and multiple groups of stirring frames 403 to approach each other. At the same time, during this process, the upper supporting box 502 continues to rotate, and the mixed liquid pushed by the downward pressing fan blade 402 is flowing from bottom to top at this time and enters the lower supporting box 501 and the upper supporting box 502 through the conical cylinder 510 below the through hole 505. During the process of the flowing mixed liquid from wide to narrow, the flowing pressure is increased, and during the flowing process, the remaining auxiliary materials in the lower supporting box 501 and the upper supporting box 502 are quickly carried above the sleeve 406 and flow back into the partition cylinder 405. At this time, multiple groups of stirring frames 403 are arranged more closely due to the compression of the upper supporting box 502. When the mixed liquid carrying more auxiliary materials flows from above to multiple groups of stirring frames 403, it will be fully stirred and mixed in the more closely arranged stirring frames 403. At the same time, the upper supporting box 502 between the partition cylinder 405 and the reaction kettle 1 continues to rotate, and the stirring plate 504 will also stir the mixed liquid, and at this time the stirring work is more concentrated, effectively improving the mixing efficiency.

[0043] During the above process, the baffle 509 opens upward under the action of hydraulic pressure, so there is almost no obstruction above the through hole 505, and the mixed liquid can quickly and fully pass through the conical cylinder 510 and pass through the lower supporting box 501 and the upper supporting box 502.

[0044] It should be noted that the lower supporting box 501 and the upper supporting box 502 cannot be separated. When the lower supporting box 501 resets upward, the upper supporting box 502 will reset together. Since the non-separable rotation mode between the lower supporting box 501 and the upper supporting box 502 belongs to the prior art, it is not shown in the drawings.

[0045] In summary of the above process, that is, first help mix the auxiliary materials and release the auxiliary materials little by little, so that the mixed liquid can simply mix multiple types of auxiliary materials. After the auxiliary materials are released to a certain extent, the mixing work of the auxiliary materials is also completed. At this time, move the lower supporting box 501 and the upper supporting box 502 downward to quickly fuse the auxiliary materials in the mixed liquid, and cooperate with the more compact multi-group stirring frames 403 and the stirring plates 504 to stir together, and cooperate with the upward flow of the mixed liquid from bottom to top to make the mixed liquid fully mixed, thereby improving the mixing efficiency.

[0046] Specifically, a rotating seat 511 is rotatably connected to the center of the top of the upper supporting box 502. Two fixing blocks 512 are symmetrically and fixedly connected to the top of the rotating seat 511. A clamping block 513 is elastically slidably connected in the fixing block 512 through a spring. A clamping groove corresponding to the clamping block 513 is opened at the output end of the hydraulic push rod 6.

[0047] When the kettle lid 2 is opened, the output end of the hydraulic push rod 6 will be disengaged from the two clamping blocks 513. When the kettle lid 2 is closed, the output end of the hydraulic push rod 6 is buckled between the two clamping blocks 513. Due to the rotational connection between the rotating seat 511 and the upper supporting box 502, the rotation of the upper supporting box 502 will not be transmitted to the hydraulic push rod 6, which is convenient for taking out the strain mixed liquid in the reaction kettle 1.

[0048] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements will not make the essence of the corresponding technical solutions deviate from the protection scope of the technical solutions of the embodiments of the present invention.
