Description

Technical Field

[0001] This application relates to the technical field of fertilizer production, and more particularly to a fermentation apparatus for the production and processing of water-soluble fertilizers. Background Technology

[0002] Water-soluble fertilizers are multi-element compound fertilizers that can be completely dissolved in water. They have advantages such as high nutrient content, good solubility, and high absorption and utilization rate, and are widely used in modern agricultural irrigation systems such as drip irrigation and sprinkler irrigation.

[0003] Currently, the fermentation equipment widely used in the production and processing of water-soluble fertilizers mainly consists of a fermentation tank, a stirring mechanism, and an aeration mechanism. The stirring mechanism typically includes a stirring motor and a stirring shaft, which drives the impeller to rotate, thereby achieving the mixing and dispersion of materials and improving the mass transfer efficiency within the reaction system. The aeration mechanism provides the necessary dissolved oxygen for aerobic fermentation by introducing air or oxygen into the tank.

[0004] However, in actual operation, existing fermentation devices still have significant shortcomings. On the one hand, due to the limited stirring range of the stirring mechanism, the stirring shaft can only drive the blades to operate on a fixed trajectory, making it difficult to effectively disturb the material near the inner wall of the tank. This leads to localized material deposition and scaling near the bottom and wall, severely affecting the uniformity of fermentation. On the other hand, the aeration mechanism is mostly fixedly installed at the bottom of the fermenter. Over long-term operation, the aeration holes are easily blocked by deposited material, obstructing the oxygen supply channel and thus affecting the dissolved oxygen input efficiency, ultimately reducing fermentation quality and production efficiency. Summary of the Invention

[0010] In one embodiment of this application, the stirring assembly includes a connecting pipe, an air intake transmission component, an auger, an auxiliary blade, a stirring paddle, and a cutter.

The auger and the stirring paddle are both mounted on the air intake transmission component. The auxiliary blade is mounted on the inner wall of the fermentation assembly. The cutter is mounted on the stirring paddle, and the cutter and the auxiliary blade are offset from each other.

[0011] In one embodiment of this application, the air intake transmission component includes a hollow rod, a mounting ring, a sliding rod, a spring, a mounting rod, a sealing plug, and a top rod. The hollow rod is connected to the connecting pipe. The mounting ring is installed inside the hollow rod. The sliding rod is slidably disposed on the mounting ring.

The spring is sleeved on the outside of the mounting rod, and both ends of the spring abut against the sealing plug and the mounting ring, respectively. The top rod is disposed on the fermentation assembly, located below the sealing plug, and engages with the sealing plug.

[0012] In one embodiment of this application, the lifting assembly includes a cylinder and a mounting plate, wherein the cylinder is mounted on the fermentation assembly, the mounting plate is mounted on the extended end of the cylinder, and the driven gear is rotatably disposed at the bottom end of the mounting plate.

[0020] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0021] The following description, in conjunction with the accompanying drawings, describes a fermentation apparatus for the production and processing of water-soluble fertilizers according to an embodiment of this application.

[0022] like Figures 1-8 As shown in the figure, a fermentation device for the production and processing of water-soluble fertilizer according to an embodiment of this application may include a support 1, and a fermentation component 2, a stirring and aeration mechanism 3 and a reflux mechanism 4 installed on the support 1.

[0023] The mixing and aeration mechanism 3 includes a drive component 31, an aeration component 32, a mixing component 33, and a lifting component 34.

[0024] It should be noted that the stirring and aeration mechanism 3 described in the above embodiments is used to stir and mix the materials in the fermentation tank 21 and to aerate and supply oxygen.

[0025] The drive assembly 31 and the lifting assembly 34 are respectively installed on the fermentation assembly 2, the aeration assembly 32 is installed on the support 1, and the stirring assembly 33 is rotatably installed inside the fermentation assembly 2, with the top of the stirring assembly 33 passing through the fermentation assembly 2 and being connected to the drive assembly 31 for transmission.

[0026] Understandably, the drive component 31 drives the stirring component 33 to rotate inside the fermentation tank 21, thereby mixing the materials. At the same time, the aeration component 32 introduces air into the stirring component 33, and the air enters the fermentation tank 21 through the stirring component 33, thereby achieving aeration and oxygen supply.

[0027] Specifically, such as Figure 3 and Figure 4 As shown, the drive assembly 31 includes a geared motor 311, a drive gear 312, and a driven gear 313.

[0028] Among them, the geared motor 311 is installed on the fermentation component 2, the drive gear 312 is rotatably installed on the fermentation component 2, the drive gear 312 is connected to the output end of the geared motor 311, and the driven gear 313 is rotatably installed on the lifting component 34, and the driven gear 313 meshes with the drive gear 312.

[0029] It should be noted that the height of the driving gear 312 described in the above embodiment is greater than that of the driven gear 31, so that when the lifting component 34 drives the driven gear 313 and the stirring component 33 to rise, the driving gear 312 can also complete the stable transmission of the driven gear 313.

[0030] Understandably, the geared motor 311 drives the drive gear 312 to rotate, and the drive gear 312 drives the driven gear 313 to rotate through meshing, and the driven gear 313 drives the stirring assembly 33 to rotate.

[0031] Specifically, such as Figure 4 As shown, the aeration assembly 32 includes an air pump 321 and a rotary joint 322.

[0032] Among them, the air pump 321 is installed on the fermentation component 2, and the air outlet of the air pump 321 is connected to the stirring component 33 through the rotary joint 322.

[0033] Understandably, the air pump 321 delivers external air into the mixing assembly 33 via the rotary joint 322. The rotary joint 322 ensures that the air passage remains unobstructed during the rotation of the mixing assembly 33.

[0034] Specifically, such as Figure 4 and Figure 5 As shown, the stirring assembly 33 includes a connecting pipe 331, an air intake transmission component 332, an auger 333, an auxiliary blade 334, a stirring paddle 335, and a cutter 336.

[0035] The connecting pipe 331 is connected to the driven gear 313. The air intake transmission component 332 is located inside the fermentation component 2. The air intake transmission component 332 passes through the fermentation component 2 and is connected to the connecting pipe 331. The auger 333 and the stirring paddle 335 are both installed on the air intake transmission component 332. The auxiliary blade 334 is installed on the inner wall of the fermentation component 2. The cutter 336 is installed on the stirring paddle 335, and the cutter 336 and the auxiliary blade 334 are staggered.

[0036] It should be noted that during the rotation process, the stirring paddle 335 completes the stirring of the accumulated fertilizer. Under the action of the stirring paddle 335, a portion of the fertilizer is crushed by the staggered auxiliary blades 334 and cutters 336. Another portion of the fertilizer is pushed to the auger 333. Subsequently, the auger 333 generates an upward pushing force when rotating, and when it is pushed to the top, it scatters in all directions. The auxiliary blades 334 and cutters 336 crush this portion of fertilizer. This not only promotes the exchange of materials between the upper and lower layers and avoids bottom sedimentation, but also improves the crushing efficiency.

[0037] Understandably, the driven gear 313 drives the air intake transmission component 332 to rotate via the connecting pipe 331. The air intake transmission component 332 then drives the auger 333 and the stirring paddle 335 to rotate, thus mixing and lifting the material. Simultaneously, the staggered cutter 336 and auxiliary blade 334, during their relative motion, can shear and break up clumps of fertilizer, thereby preventing incomplete fermentation due to fertilizer clumping.

[0038] Specifically, such as Figure 5 and Figure 6 As shown, the intake transmission component 332 includes a hollow rod 3321, a mounting ring 3322, a slide rod 3323, a spring 3324, a mounting rod 3325, a sealing plug 3326, and a push rod 3327.

[0039] The hollow rod 3321 is connected to the connecting pipe 331. The mounting ring 3322 is installed inside the hollow rod 3321. The sliding rod 3323 is slidably mounted on the mounting ring 3322. The two ends of the mounting rod 3325 are connected to the sliding rod 3323 and the sealing plug 3326 respectively. The bottom end of the hollow rod 3321 has a through hole for the sealing plug 3326 to engage. The spring 3324 is sleeved on the outside of the mounting rod 3325. The two ends of the spring 3324 abut against the sealing plug 3326 and the mounting ring 3322 respectively. The top rod 3327 is mounted on the fermentation component 2. The top rod 3327 is located below the sealing plug 3326 and cooperates with the sealing plug 3326.

[0040] Understandably, the lifting assembly 34 causes the air intake transmission component 332 to descend, and then the sealing plug 3326 in the hollow rod 3321 is pushed upward by the top rod 3327. The mounting rod 3325 and the spring 3324 move upward, while the sliding rod 3323 slides in the mounting ring 3322, causing the sealing plug 3326 to disengage from the through hole at the bottom of the hollow rod 3321. At this time, the gas that enters the hollow rod 3321 through the air pump 321 and the rotary joint 322 is discharged through the through hole, thereby supplying oxygen during the fermentation process. When fermentation is completed, the lifting assembly 34 causes the air intake transmission component 332 to rise. Under the action of the spring 3324, the sealing plug 3326 moves downward and blocks the through hole at the bottom of the hollow rod 3321, preventing fertilizer from entering the hollow rod 3321 and effectively preventing the aeration holes from becoming blocked, which would prevent oxygen from being supplied.

[0041] Specifically, such as Figure 4 As shown, the lifting assembly 34 includes a cylinder 341 and a mounting plate 342.

[0042] The cylinder 341 is mounted on the fermentation component 2, the mounting plate 342 is mounted on the extended end of the cylinder 341, and the driven gear 313 is rotatably mounted on the bottom end of the mounting plate 342.

[0043] Understandably, the cylinder 341 drives the driven gear 313 and the stirring assembly 33 to rise and fall through the mounting plate 342, thereby adjusting the position of the stirring assembly 33 in the fermentation tank 21 and effectively preventing the aeration holes from being blocked, which would prevent oxygen from being supplied.

[0044] The reflux mechanism 4 includes a reflux component 41 and a defoaming component 42.

[0045] It should be noted that the reflux mechanism 4 described in the above embodiments is used to circulate the fermentation liquid back to avoid waste of the fermentation liquid.

[0046] The reflux component 41 is connected to the fermentation component 2, and the defoaming component 42 is installed on the reflux component 41, with the stirring end of the defoaming component 42 extending into the interior of the reflux component 41.

[0047] Specifically, such as Figure 7 and Figure 8 As shown, the reflux assembly 41 includes a reflux frame 411, a reflux pipe 412, a liquid storage tank 413, a drain pipe 414, and a cone plate 415.

[0048] It should be noted that the liquid storage tank 413 described in the above embodiment is equipped with a liquid pump (not shown in the figure), and the liquid outlet of the liquid pump is connected to the drain pipe 414, so that the fermentation liquid entering the liquid storage tank 413 is discharged back into the fermentation component 2.

[0049] It should be noted that the cone mesh plate 415 described in the above embodiment is equipped with several cone-shaped protrusions, thereby achieving the puncture treatment of the foam that has not been eliminated by the defoaming component 42.

[0050] The reflux frame 411 is connected to the fermentation component 2, the liquid storage tank 413 is installed on the support 1, the reflux frame 411 is connected to the liquid storage tank 413 through the reflux pipe 412, the liquid storage tank 413 is connected to the fermentation component 2 through the drain pipe 414, and the cone mesh plate 415 is installed inside the reflux frame 411.

[0051] Understandably, the defoaming component 42 eliminates foam in the fermentation tank 21. A portion of the fermentation liquid adhering to the defoaming component 42 is thrown into the reflux frame 411 by centrifugal force, then flows through the reflux pipe 412 into the storage tank 413, and finally returns to the fermentation tank 21 via the drain pipe 414, forming a circulating reflux. The cone mesh plate 415 can further break down and eliminate any remaining unbroken foam adhering to the defoaming component 42.

[0052] Specifically, such as Figure 7 and Figure 8 As shown, the defoaming component 42 includes a mounting bracket 421, a servo motor 422, and blades 423.

[0053] The mounting bracket 421 is mounted on the return frame 411 via the return frame 411, the blade 423 is rotatably mounted on the return frame 411, and the output end of the servo motor 422 passes through the return frame 411 and is connected to the blade 423 for transmission.

[0054] Understandably, the servo motor 422 drives the blades 423 to rotate at high speed within the reflux frame 411, breaking up and eliminating the foam generated during the reflux process, thus preventing foam accumulation from affecting the fermentation effect.

[0055] The above-described implementation method can simultaneously break up clumps of fertilizer during the mixing process, effectively eliminating material agglomerates and maintaining the homogeneity of the system. At the same time, the optimized arrangement of the aeration mechanism can prevent sediment from clogging the aeration holes, ensuring a continuous and stable input of dissolved oxygen, thereby significantly improving fermentation efficiency and product quality.

[0056] In one embodiment of this application, such as Figure 2 As shown, the fermentation component 2 includes a fermentation tank 21, a baffle 22, a feeding pipe 23, and a discharge pipe 24.

[0057] The fermentation tank 21 is mounted on the support 1, the baffle 22 is mounted on the fermentation tank 21, the feeding pipe 23 is connected to the fermentation tank 21 and is located on one side of the baffle 22, and the discharge pipe 24 is connected to the bottom of the fermentation tank 21 and passes through the support 1.

[0058] Understandably, the material is fed into the fermentation tank 21 through the feeding pipe 23, and the baffle 22 can prevent the material from splashing; thus avoiding the material from affecting the stirring and aeration mechanism 3 during the feeding process. After fermentation is completed, the finished product is discharged through the discharge pipe 24.

[0059] Furthermore, such as Figure 2 As shown, the baffle 22 is arranged in an arc shape, and the arc surface of the baffle 22 faces the feeding pipe 23.

[0060] It should be noted that the arc-shaped baffle 22 can prevent materials from splashing onto the mixing and aeration mechanism 3 and the return mechanism 4 during the material feeding process, thereby protecting the mixing and aeration mechanism 3 and the return mechanism 4 and extending their service life.

[0061] Furthermore, such as Figure 3 and Figure 4 As shown, the fermentation device for the production and processing of water-soluble fertilizer also includes a controller (not shown in the figure). The controller is electrically connected to the geared motor 311, the air pump 321, the cylinder 341 and the servo motor 422 respectively, and is used to control the coordinated operation of each component.

[0062] Understandably, the controller can set the speed of the geared motor 311, the air supply of the air pump 321, the extension and retraction stroke of the cylinder 341, and the speed of the servo motor 422 to achieve automated control of the fermentation process.

[0063] Furthermore, multiple sets of cutters 336 are arranged at intervals along the extension direction of the agitator 335, and the blades of the cutters 336 face the same direction as the rotation direction of the agitator 335.

[0064] Understandably, multiple sets of cutters 336 can increase the shearing frequency and shearing area of ​​clumped fertilizer, thereby improving the crushing effect.

[0065] Specifically, the auxiliary blades 334 are installed at different heights on the inner wall of the fermentation tank 21, and each auxiliary blade 334 is evenly distributed along the circumference of the fermentation tank 21.

[0066] It is understandable that the auxiliary blades 334 at different heights can cooperate with the cutters 336 at different heights to break up the clumps of material at different depths within the fermentation unit 2.

[0067] Furthermore, the sealing plug 3326 is configured in a frustum-shaped structure, with the top end being larger than the bottom end.

[0068] Understandably, the frustoconical sealing plug 3326 can better form a sealing fit with the through hole at the bottom of the hollow rod 3321, thereby improving the sealing effect.

[0069] Specifically, the outer surface of the sealing plug 3326 is covered with a rubber sealing layer.

[0070] Understandably, the rubber sealing layer can improve the sealing performance between the sealing plug 3326 and the through hole, preventing material from flowing back into the hollow rod 3321 in a non-venting state.

[0071] Furthermore, the blade 423 is turbine-type, and the rotation center of the blade 423 coincides with the central axis of the return frame 411.

[0072] Understandably, the turbine blades 423 can generate strong shearing force when rotating at high speed, which can quickly break up the foam and improve the defoaming efficiency.

[0073] Specifically, the fermentation device for water-soluble fertilizer production and processing provided in this application can be used for aerobic fermentation operations in the production process of water-soluble fertilizer. In actual operation, the relevant personnel first put the material to be fermented into the fermentation tank 21 through the feeding pipe 23. The baffle 22 prevents the material from scattering to the starting reduction motor 311. The reduction motor 311 is started, and the reduction motor 311 drives the driven gear 313 to rotate through the driving gear 312. The driven gear 313 drives the hollow rod 3321 and the auger 333 and stirring paddle 335 installed on it to rotate through the connecting pipe 331, so as to fully stir and mix the material. During the stirring process, the cutter 336 installed on the stirring paddle 335 and the auxiliary blade 334 fixed on the inner wall of the fermentation tank 21 are staggered to cut and break up the clumps of fertilizer, maintaining the homogeneity of the fermentation system.

[0074] Simultaneously, the air pump 321 is activated, and external air enters the hollow rod 3321 through the rotary joint 322. The air descends along the hollow rod 3321 to the bottom, and under the action of the lifting component 34, it drives the air intake transmission component 332 to descend. Subsequently, the sealing plug 3326 in the hollow rod 3321 is pushed open upward by the top rod 3327, the mounting rod 3325 and the spring 3324 move upward, and the sliding rod 3323 slides in the mounting ring 3322, causing the sealing plug 3326 to disengage from the through hole at the bottom of the hollow rod 3321. At this time, the gas that enters the hollow rod 3321 through the air pump 321 and the rotary joint 322 is discharged through the through hole, thereby achieving the supply of oxygen during the fermentation process.

[0075] During fermentation, the defoaming component 42 eliminates the foam in the fermentation tank 21. The fermentation liquid adhering to the defoaming component 42 is thrown into the reflux frame 411 by centrifugal force, and then enters the storage tank 413 through the reflux pipe 412. It then flows back into the fermentation tank 21 through the drain pipe 414, forming a circulation. At the same time, some foam that is not broken by the high-speed rotating blades 423 is pushed into the reflux frame 411 and comes into contact with the cone mesh plate 415, thereby improving the efficiency of foam breaking. After fermentation, the lifting component 34 drives the air intake transmission component 332 to rise. Under the action of the spring 3324, the sealing plug 3326 moves downward and blocks the through hole at the bottom of the hollow rod 3321, preventing fertilizer from entering the hollow rod 3321. This effectively prevents the aeration holes from being blocked and causing oxygen supply to fail. The fermented product is then discharged through the discharge pipe 24. Through the above process, efficient stirring, uniform aeration, circulation and defoaming are integrated into the fermentation process of water-soluble fertilizers, which significantly improves fermentation efficiency and product quality.

[0076] In summary, the fermentation device for water-soluble fertilizer production and processing according to the embodiments of this application can simultaneously crush agglomerated fertilizer during the stirring process, effectively eliminate material agglomerates, and maintain the homogeneity of the system. At the same time, through the optimized arrangement of the aeration mechanism, it can prevent sediment from clogging the aeration holes, ensure the continuous and stable input of dissolved oxygen, thereby significantly improving fermentation efficiency and product quality.
