Description

Technical Field

[0001] This utility model belongs to the field of bio-organic fertilizer production technology, and in particular, it is a high-efficiency fermentation device for bio-organic fertilizer production. Background Technology

[0002] Bio-organic fertilizer, as a new type of environmentally friendly and nutrient-rich fertilizer, plays an increasingly important role in the sustainable development of modern agriculture. The core step in its production process is fermentation, typically carried out in specialized fermentation tanks. As key equipment for the high-temperature composting, harmless treatment, and stabilization transformation of organic materials under the action of microorganisms, the performance of the fermentation tank directly determines the product quality, production efficiency, and operating costs of the organic fertilizer. A typical fermentation tank mainly includes a tank body, a stirring device, a feeding and discharging system, and a temperature and humidity control system. Mechanical stirring promotes material mixing, heat and mass transfer, and oxygen supply to ensure uniform and efficient fermentation.

[0003] However, in actual production, existing bio-organic fertilizer fermentation devices generally suffer from serious technical defects such as easy material sticking to the walls, uneven mixing, and poor crushing effect. These defects not only stem from the limitations of the equipment structure design but also trigger a series of chain-like negative consequences, seriously affecting the continuity, safety, and product quality of production. First, the problem of severe material sticking to the walls is mainly due to the physicochemical properties of organic raw materials. Raw materials used to produce bio-organic fertilizer, such as livestock and poultry manure, kitchen waste, and straw powder, generally have high moisture content (often exceeding 60%) and are rich in colloidal proteins and polysaccharides. Under high-temperature (50-70℃) fermentation conditions, they easily form highly adhesive wet clumps. Existing fermentation tanks often use vertically arranged paddles or spiral belt structures, which generate relatively small shear forces near the inner wall of the tank during rotation, failing to effectively peel off the adhered material. Over time, these adhered substances accumulate and thicken, forming a dense "wall-hanging layer." If this problem is not solved, it will have multiple serious consequences: On the one hand, the wall-mounted layer occupies a large amount of effective volume, resulting in a reduction in the amount of material fed at one time, which reduces equipment utilization and production efficiency; on the other hand, because the material in this layer is separated from the main mixing zone, it cannot get sufficient oxygen and heat transfer, and anaerobic bacteria inside multiply in large numbers, producing malodorous gases and harmful substances such as hydrogen sulfide and ammonia. This not only pollutes the workshop environment, but may also cause this part of the material to rot and deteriorate, eventually mixing into the finished product, seriously affecting the quality stability of organic fertilizer. Utility Model Content

[0004] The purpose of this invention is to provide a high-efficiency fermentation device for the production of bio-organic fertilizer, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency fermentation device for the production of bio-organic fertilizer, comprising:

[0006] Fermentation tank, used for the fermentation reaction of bio-organic fertilizer;

[0007] The stirring shaft is rotatably installed inside the fermenter.

[0008] A material shovel disturbance body is longitudinally arranged in a fermentation tank. The outer wall of the material shovel disturbance body is in sliding frictional contact with the inner wall of the fermentation tank. The material shovel disturbance body includes a sharp material shovel end, a material shovel arc-shaped slope integrally connected to the sharp material shovel end, a discharge transition end integrally connected to the material shovel arc-shaped slope, and a contact friction curved surface that is in contact with the inner wall of the fermentation tank. The end of the contact friction curved surface that is away from the sharp material shovel end extends and is integrally connected with the discharge transition end.

[0009] The material scraper is connected to the stirring shaft, which drives the material scraper to rotate inside the fermentation tank. This causes the sharp scraper tip to scrape off the organic fertilizer adhering to the inner wall of the fermentation tank, and the organic fertilizer located on the side of the fermentation tank to slide smoothly along the arc-shaped trajectory of the material scraper's arc-shaped slope, and be crushed by the material turning and crushing component on the material scraper's arc-shaped slope.

[0010] In this preferred embodiment, both the upper and lower ends of the stirring shaft are fitted with fixing rings, and each fixing ring is fixedly connected to the stirring shaft by a locking bolt.

[0011] In this preferred embodiment, support rods are welded to both the upper and lower ends of the outer wall of the unloading transition end, and the ends of the two support rods away from the unloading transition end are respectively welded to one side of the outer wall of the two fixing collars.

[0012] In a preferred embodiment, multiple sets of first shearing components are equidistantly arranged on one side of the unloading transition end and on the outer wall of the material scraping disturbance body. Each set of first shearing components includes a first horizontal blade in the middle position, a first downward tilting blade above the first horizontal blade, and a first upward tilting blade below the first horizontal blade. One end of the first horizontal blade, the first downward tilting blade, and the first upward tilting blade are all fixed to the outer wall of the material scraping disturbance body, and the other end is all fixed to the outer wall of the stirring shaft.

[0013] In this preferred embodiment, the first cutting head ends of the first horizontal blade, the first downward-sloping blade, and the first upward-sloping blade are all close to one side of the shovel-shaped curved slope, so as to shear the clumps of organic fertilizer from the front.

[0014] In this preferred embodiment, a connecting rod is welded to the side of each of the two fixed collars facing away from the support rod, and a scraping strip is welded between the ends of the two connecting rods away from the fixed collars. Both sides of the scraping strip have sharp, double-headed scraping ends for scraping off organic fertilizer adhering to the inner wall of the fermentation tank.

[0015] In a preferred embodiment, multiple sets of second shearing components are equidistantly arranged between the connecting rod and the stirring shaft. Each set of second shearing components includes a second horizontal blade at the middle position, a second downward-sloping blade above the second horizontal blade, and a second upward-sloping blade below the second horizontal blade. One end of the second horizontal blade, the second downward-sloping blade, and the second upward-sloping blade is fixed to the outer wall of the stirring shaft, and the other end is fixed to the inner wall of the shovel bar.

[0016] In this preferred embodiment, the second cutting head ends of the second horizontal blade, the second downward-sloping blade, and the second upward-sloping blade have opposite cutting directions to the first cutting head end, so that the second cutting head end can cut the clumps of organic fertilizer that are smoothly tracing the arc-shaped slope of the shovel.

[0017] In a preferred embodiment, at least three second sealed bearings are longitudinally and equidistantly embedded in the inner wall of the shovel-shaped arc slope. The inner rings of the upper and lower second sealed bearings are interference-fitted with first connecting shafts, and the inner rings of the middle second sealed bearing are interference-fitted with second connecting shafts. The material turning and crushing assembly includes stirring blades installed on the outer walls of the free ends of the two first connecting shafts and a material turning plate installed on the outer walls of the free ends of the second connecting shafts.

[0018] In a preferred embodiment, the top surface of the fermenter is fitted with a tank lid by screws, a mounting bracket is installed at the middle of the top surface of the tank lid, a servo motor is installed on the top surface of the mounting bracket, and the top end of the stirring shaft extends upward through the tank lid into the mounting bracket and is fixedly connected to the output shaft of the servo motor.

[0019] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0020] This high-efficiency fermentation device for bio-organic fertilizer production utilizes a material scraper that rotates longitudinally within the fermentation tank, synchronized with the stirring shaft. Its outer wall is designed with a sliding friction surface that closely adheres to the inner wall of the tank. This allows the device to continuously and forcefully scrape away the wet, sticky organic fertilizer adhering to the fermentation tank's inner wall during operation. The sharp scraper tip at the front of the material scraper cuts into the adhesive layer like a plow, effectively breaking the adhesion between the material and the metal wall, preventing the formation of a thick, heat-insulating layer that hinders mass transfer. The scraped-off material and side deposits then slide backward along the smooth curved surface of the integrated, arc-shaped slope behind it, creating a directional flow. This collaborative design of "active wall cleaning + flow guiding and shaping" not only solves the problems of reduced effective volume, local overheating or fermentation stagnation caused by material sticking to the wall in traditional fermentation equipment, but also guides the material with poor flowability in the side wall area into the main stirring zone, realizing material circulation and renewal throughout the entire tank. Compared with existing technologies, it significantly improves the uniformity of fermentation reaction and heat exchange efficiency, and avoids production interruptions and safety hazards caused by manual shutdown for cleaning.

[0021] By integrating multi-stage shearing and independently driven material-tumbling and crushing components into the material-shoveling disturbance body, the agglomerated material sliding down the curved slope of the shovel is efficiently crushed and thoroughly mixed during its descent. Specifically, the first horizontal blade, the first downward-sloping blade, and the first upward-sloping blade in the first shearing component are arranged in a three-dimensional staggered pattern and rotate at high speed with the main shaft. The first blade tip facing the material can perform face-to-face shearing on the sliding material flow, quickly breaking up large clumps. At the same time, the second shearing component between the shovel bar and the stirring shaft forms a cross-shearing network with the second blade tips in opposite directions, further refining the material. The dual shearing structure significantly improves crushing efficiency and uniformity. More importantly, the second sealed bearing embedded in the curved slope of the shovel supports the first and second connecting shafts, and the built-in drive motor independently drives the stirring blades and the tipping plate to rotate at high speed, realizing the composite function of "dynamic tipping + active crushing": the tipping plate throws the material high up, exposing it fully to the air to increase oxygenation, while it falls into the high-speed rotating stirring blades and is thoroughly crushed. This multi-dimensional, multi-stage crushing and mixing process results in highly uniform particle size of organic fertilizer materials, allowing for more thorough contact between microorganisms and nutrients. Compared to existing technologies that rely solely on simple stirring paddles, this process significantly accelerates the composting process and improves the quality stability and fertilizer release consistency of the final product.

[0031] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0032] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0033] This embodiment provides, for example Figures 1 to 6 The high-efficiency fermentation device for producing bio-organic fertilizer shown includes:

[0034] Fermentation tank 1 is used for the fermentation reaction of bio-organic fertilizer;

[0035] The stirring shaft 8 is rotatably installed inside the fermenter 1;

[0036] The material scraping disturbance body 10 is longitudinally arranged in the fermentation tank 1. The outer wall of the material scraping disturbance body 10 is in sliding friction contact with the inner wall of the fermentation tank 1. The material scraping disturbance body 10 includes a sharp material scraping end 11, a material scraping arc-shaped slope 12 integrally connected to the sharp material scraping end 11, a discharge transition end 19 integrally connected to the material scraping arc-shaped slope 12, and a contact friction curved surface 20 that is in contact with the inner wall of the fermentation tank 1. The end of the contact friction curved surface 20 away from the sharp material scraping end 11 extends and is integrally connected with the discharge transition end 19.

[0037] The material scraper 10 is connected to the stirring shaft 8. The stirring shaft 8 drives the material scraper 10 to rotate in the inner cavity of the fermentation tank 1, so that the sharp scraper end 11 scrapes away the organic fertilizer that is attached to the inner wall of the fermentation tank 1. This causes the organic fertilizer and the organic fertilizer located on the side of the inner cavity of the fermentation tank 1 to slide smoothly along the arc trajectory of the material scraper arc slope 12 and be crushed by the material turning and crushing component on the material scraper arc slope 12.

[0038] In this embodiment, both the upper and lower ends of the stirring shaft 8 are fitted with fixing collars 15, and each fixing collar 15 is fixedly connected to the stirring shaft 8 by a locking bolt 16.

[0039] In this embodiment, support rods 17 are welded to both the upper and lower ends of the outer wall of the unloading transition end 19. The ends of the two support rods 17 away from the unloading transition end 19 are respectively welded to one side of the outer wall of the two fixing collars 15. The support rods 17 firmly weld the unloading transition end 19 to the fixing collars 15, effectively enhancing the structural strength and stability of the entire shovel disturbance body 10 under high-speed rotation and material impact, preventing deformation or breakage.

[0040] In this embodiment, multiple sets of first shearing components are equidistantly arranged on one side of the unloading transition end 19 and on the outer wall of the material scraping disturbance body 10. Each set of first shearing components includes a first horizontal blade 26 in the middle position, a first downward blade 27 above the first horizontal blade 26, and a first upward blade 28 below the first horizontal blade 26. One end of the first horizontal blade 26, the first downward blade 27, and the first upward blade 28 are all fixed to the outer wall of the material scraping disturbance body 10, and the other end is all fixed to the outer wall of the stirring shaft 8.

[0041] In this embodiment, the first cutting head 32 of the first horizontal blade 26, the first downward-sloping blade 27, and the first upward-sloping blade 28 are all close to one side of the shovel-shaped curved slope 12, so as to shear the clumps of organic fertilizer from the front.

[0042] In this embodiment, connecting rods 14 are welded to the side of the two fixing collars 15 facing away from the support rod 17. A scraper strip 13 is welded between the ends of the two connecting rods 14 away from the fixing collars 15. Both sides of the scraper strip 13 have double-headed sharp scraper ends 18 for scraping off the organic fertilizer attached to the inner wall of the fermentation tank 1.

[0043] In this embodiment, multiple sets of second shearing components are equidistantly arranged between the connecting rod 14 and the stirring shaft 8. Each set of second shearing components includes a second horizontal blade 29 at the middle position, a second downward-tilting blade 30 above the second horizontal blade 29, and a second upward-tilting blade 31 below the second horizontal blade 29. One end of the second horizontal blade 29, the second downward-tilting blade 30, and the second upward-tilting blade 31 is fixed to the outer wall of the stirring shaft 8, and the other end is fixed to the inner wall of the shovel bar 13.

[0044] In this embodiment, the second cutting head end 33 of the second horizontal blade 29, the second downward-sloping blade 30, and the second upward-sloping blade 31 has the opposite cutting direction to the first cutting head end 32, so that the second cutting head end 33 can cut the clumps of organic fertilizer that are smoothly along the trajectory of the shovel-shaped slope 12.

[0045] In this embodiment, at least three second sealed bearings 21 are longitudinally and equidistantly embedded in the inner wall of the shovel-shaped arc slope 12. The inner rings of the upper and lower second sealed bearings 21 are interference-fitted with the first connecting shafts 24, and the inner rings of the middle second sealed bearing 21 are interference-fitted with the second connecting shafts 25. The material turning and crushing assembly includes stirring blades 22 installed on the outer walls of the free ends of the two first connecting shafts 24 and a turning plate 23 installed on the outer walls of the free ends of the second connecting shafts 25. After the sharp shovel end 11 removes and scrapes off the organic fertilizer, this part of the fertilizer and the organic fertilizer already in the cavity of the fermentation tank 1 are allowed to slide smoothly along the trajectory of the shovel-shaped arc slope 12. If the smooth fertilizer first encounters the turning plate 23, it can be turned up and down by the turning plate 23. When turning up and down, the fertilizer is thrown onto the two stirring blades 22, and crushed by the stirring blades 22. The part of the fertilizer that first comes into contact with the stirring blades 22 is crushed first, and then fully mixed by the stirring and turning by the turning plate 23.

[0046] In this embodiment, a lid 2 is screwed onto the top surface of the fermenter 1. A mounting bracket 3 is installed in the middle of the top surface of the lid 2. A servo motor 4 is installed on the top surface of the mounting bracket 3. The top end of the stirring shaft 8 extends upward through the lid 2 into the mounting bracket 3 and is fixedly connected to the output shaft of the servo motor 4. A feed pipe 5 is connected through the top surface of the lid 2 on one side of the mounting bracket 3. Multiple support feet 6 are fixed in a circular array on the bottom surface of the fermenter 1. A discharge pipe 7 is connected through the bottom surface of the fermenter 1. The bottom end of the stirring shaft 8 is connected to the inner bottom wall of the fermenter 1 through a first sealed bearing 9.

[0047] In this embodiment, at least three drive motors (as shown in the attached figure) are installed at equal intervals on the inner wall of the material-shoveling arc-shaped slope 12 and behind it. Figure 6Two drive motors A are provided, each driving one of the two first couplings 24; while one drive motor B is provided, driving one second coupling 25. The output ends of the three drive motors are connected to the two first couplings 24 and one second coupling 25 respectively, thereby driving the stirring blade 22 and the tilting plate 23 to rotate. In addition, there is a battery in the sealed inner cavity of the material scraping disturbance body 10 to power the three drive motors. At the same time, the inner cavity of the material scraping disturbance body 10 also has a wireless receiving module and a wireless control switch to control the opening and closing of the drive motors. The wireless receiving module is used to receive wireless signal control commands from the PLC in the external workshop power distribution cabinet.

[0048] Working principle

[0049] This high-efficiency fermentation device for producing bio-organic fertilizer involves opening the feed pipe 5 at the top of tank cover 2 and feeding the prepared organic fertilizer raw materials (such as livestock and poultry manure, straw, and microbial inoculants) into the inner cavity of fermentation tank 1. After feeding is complete, the cover of feed pipe 5 is closed. An external power supply is then connected to power the servo motor 4. Simultaneously, the battery inside the material shovel agitator 10 is pre-charged to power the built-in drive motor. The wireless receiver module is in standby mode and can receive wireless control commands from the PLC (Programmable Logic Controller) in the workshop power distribution cabinet.

[0050] The servo motor 4 is started, and its output shaft is connected to the top of the stirring shaft 8 via a coupling, driving the entire stirring shaft 8 to rotate within the fermentation tank 1. The stirring shaft 8 forms a rotational support with the bottom wall of the fermentation tank 1 via the first sealed bearing 9 at the bottom, ensuring smooth operation and good sealing. As the stirring shaft 8 rotates, the material scraping agitator 10, which is rigidly connected to it, rotates synchronously. The sharp scraping end 11 at the front end of the material scraping agitator 10, like a plow, scrapes against the inner wall of the fermentation tank 1, forcefully removing the wet, sticky organic fertilizer adhering to the tank wall. The scraped material, as well as the material that was originally close to the tank wall, slides smoothly backward along the smooth curved surface of the scraping arc slope 12 under the combined action of centrifugal force and gravity, forming an orderly material flow trajectory and avoiding dead corners where material accumulates.

[0051] The first shearing assembly (including the first horizontal blade 26, the first downward-tilting blade 27, and the first upward-tilting blade 28) located outside the unloading transition end 19 rotates at high speed with the main shaft. Their first cutter heads 32 face the direction of material sliding, cutting off large pieces or caking materials that may be sliding down the shovel-shaped slope 12 like scissors, thus achieving preliminary crushing.

[0052] The material, after initial shearing, continues to flow downwards into the area comprised of the turning and crushing components. At this point, three independent drive motors activate, driving the two first connecting shafts 24 and the second connecting shaft 25 to rotate. The stirring blades 22 mounted on the first connecting shafts 24 rotate rapidly, cutting and breaking up the flowing material. The turning plates 23 mounted on the second connecting shafts 25 act like paddles, throwing the material upwards or outwards. This design achieves a dual effect of "throwing before crushing" or "crushing before throwing": if the material first encounters the turning plates 23, it is thrown high into the air and then falls into the high-speed rotating stirring blades 22 for thorough crushing; if the material first encounters the stirring blades 22, it is crushed first and then stirred and tossed by the turning plates 23, ensuring thorough and uniform mixing of new and old, dry and wet materials, greatly improving the uniformity and efficiency of fermentation.

[0053] Meanwhile, the second shearing assembly (including the second horizontal blade 29, the second downward-tilting blade 30, and the second upward-tilting blade 31) located between the shovel bar 13 and the stirring shaft 8 also rotates under the drive of the main shaft. The shearing direction of its second cutter head 33 is opposite to that of the first cutter head 32, forming a cross-shearing network to further process the material flow sliding down the arc-shaped slope 12 of the shovel. It is particularly good at processing material bundles with a specific orientation generated by the first-stage shearing, ensuring thorough crushing without any omissions.

[0054] The connecting rod 14 and the scraper bar 13, which are welded to the fixed collar 15, rotate with the main shaft. The sharp ends 18 of the double-headed scrapers on both sides can scrape off the tank wall attached to the middle height range of the fermentation tank 1. In conjunction with the main scraper disturbing body 10, they can achieve material cleaning.

[0055] The entire fermentation process is centrally monitored by the workshop's PLC system. The PLC sends commands wirelessly to the wireless receiving module inside the material-shoveling agitator 10. Based on the received commands, the wireless control switch controls the start / stop, speed, and forward / reverse rotation of the three drive motors, thereby precisely adjusting the working state of the stirring blades 22 and the turning plate 23 to meet the needs of different fermentation stages (such as vigorous stirring in the initial stage, moderate turning in the middle stage, and low-speed mixing in the later stage). The spindle's servo motor 4 also has its speed controlled by the PLC, achieving intelligent management of the overall stirring intensity.

[0056] When fermentation reaches the predetermined time, the PLC issues a stop command. The drive motors in servo motor 4 and the material scraper 10 all stop working. The discharge pipe 7 valve at the bottom of fermentation tank 1 is opened to discharge the material.
