Description

Technical Field

[0001] The present invention relates to the technical field of bio-agriculture, and particularly relates to a powder solid-state biological fermentation device. Background Art

[0002] At present, with the booming development of bio-agriculture, the powder solid-state biological fermentation technology plays a key role in the production of products such as bio-fertilizers and bio-pesticides by virtue of its unique advantages. In terms of bio-fertilizers, through fermentation, organic materials are converted into high-efficiency fertilizers rich in various nutrient elements and beneficial microorganisms, which can effectively improve the soil structure, enhance soil fertility, provide continuous nutrient support for crop growth, and contribute to the development of green and sustainable agriculture. In the preparation of bio-pesticides, this technology can promote the microbial metabolism to generate substances with insecticidal and bactericidal activities. These bio-based pesticides are more environmentally friendly than traditional chemical pesticides, are not easily residual, can accurately prevent and control pests and diseases, and can also reduce the negative impact on the ecosystem. As the core carrier of the above technology, the powder solid-state biological fermentation device can create a stable and suitable fermentation environment for microorganisms, strictly control key parameters such as temperature and humidity, ensure the efficient growth and metabolism of microorganisms, and thus improve the quality and yield of bio-fertilizers and bio-pesticides.

[0003] During the fermentation process using a powder solid-state biological fermentation device, the materials are prone to adhering to the inner wall of the tank. Especially for some fermentation liquids with high viscosity or materials containing solid particles, as the fermentation progresses, the adhered materials will accumulate more and more, which will not only affect the effective volume of the fermentation tank, but may also cause problems such as excessive growth of microorganisms at the wall-hanging place and accumulation of metabolites, thereby affecting the fermentation quality, and increasing the difficulty and frequency of cleaning. On the other hand, the stirring mechanism of the fermentation device usually can only stir the fermentation liquid within a certain range, and it is easy to form a stirring dead angle near the tank wall. At these dead angles, the flow rate of the materials is slow, the mixing is uneven, resulting in inconsistent growth environments for microorganisms, and affecting the stability of fermentation and the product quality. Summary of the Invention

[0004] The purpose of the present invention is to provide a powder solid-state biological fermentation device to solve the problem that the inner wall of the existing biological fermentation device is prone to adhering materials, which will not only affect the effective volume of the fermentation tank, but may also cause excessive growth of microorganisms at the wall-hanging place and accumulation of metabolites.

[0005] To achieve the above object, the present invention adopts the following technology: a powder solid-state biological fermentation device, including a tank body, the top of the tank body is detachably connected with a tank cover through bolt fasteners, symmetrically arranged on the top of the tank cover are a feed inlet and an exhaust pipe communicating with the inside of the tank body, and the bottom of the tank body is provided with a discharge port communicating with its inside. A stirring mechanism for improving the mixing effect of materials and removing attachments is arranged on the tank cover, and a self-rotation mechanism for the self-rotation of the tank body is arranged on the tank body;

[0006] The tank body rotates in a direction opposite to the stirring direction of the stirring mechanism through the self-rotation mechanism, cooperating with the stirring mechanism to improve the material mixing effect and strengthen the cleaning effect of the attachments on the inner wall of the tank body.

[0007] As a further description of the above technical solution: the stirring mechanism includes a motor group fixed on the top of the tank cover, the output end of the motor group is provided with a stirring shaft located inside the tank body, and blades are arranged on the stirring shaft.

[0008] As a further description of the above technical solution: the stirring mechanism further includes a scraping component arranged on the blades;

[0009] The scraping component includes a connecting frame connected to the blade, and a scraping plate abutted against the inner wall of the tank body is arranged on the connecting frame.

[0010] As a further description of the above technical solution: sliding rails are arranged on the blades, and sliding grooves matched with the sliding rails are formed on the connecting frame, and locking bolts are arranged on the connecting frame.

[0011] As a further description of the above technical solution: the scraping plate is detachably connected to the connecting frame through a connecting shaft, a spring is sleeved on the connecting shaft, and a locking nut abutted against the connecting frame is arranged at one end of the connecting shaft through a threaded end.

[0012] As a further description of the above technical solution: a number of conical teeth are arranged on the blades at equal intervals along their length directions.

[0013] As a further description of the above technical solution: the self-rotation mechanism includes a bracket, a connecting rod connected to the bottom of the tank body is arranged on the bracket through a fixing plate, and a driving component for driving the connecting rod to rotate is arranged on the fixing plate.

[0014] As a further description of the above technical solution: the driving component includes a driving motor arranged at the bottom of the fixing plate, a transmission belt is arranged on the output end of the driving motor through a pulley, and a transmission wheel matched with the transmission belt is arranged on the connecting rod.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0016] When the tank body rotates on its own axis and the scraper is fixed on the stirring mechanism, the movement track of the scraper relative to the tank wall is more complex, ensuring that the scraper can cover every corner of the inner wall of the tank body, strengthening the cleaning effect. The rotation direction of the tank body is opposite to that of the stirring mechanism, causing the relative speed between the scraper and the tank wall to be superimposed, increasing the wiping force. When scraping stubborn dirt on the tank wall, it can more effectively peel the dirt from the tank wall, ensuring the cleanliness of the tank wall;

[0017] During the production process of fermented feed, the raw materials may agglomerate. The taper teeth can break up these agglomerates during the stirring process, increasing the contact area between microorganisms and the material, and improving the fermentation efficiency.

[0027] 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. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. 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.

[0028] Referring to Figures 1-7 , a powder solid-state biological fermentation device provided in this embodiment includes a tank body 1. The top of the tank body 1 is detachably connected with a tank cover 2 through bolt fasteners. Symmetrically arranged on the top of the tank cover 2 are a feed inlet 3 and an exhaust pipe 5 that are connected to the inside of the tank body 1, and the bottom of the tank body 1 is provided with a discharge port 4 that is connected to its inside. A stirring mechanism 6 for improving the mixing effect of materials and removing attachments is arranged on the tank cover 2. A self-rotation mechanism 7 for the self-rotation of the tank body 1 is arranged on the tank body 1. The tank body 1 rotates in a direction opposite to the stirring direction of the stirring mechanism 6 through the self-rotation mechanism 7, cooperating with the stirring mechanism 6 to improve the material mixing effect and strengthen the cleaning effect of the attachments on the inner wall of the tank body 1.

[0029] In the present invention, the raw materials for fermentation enter the inside of the tank body 1 through the feed inlet 3 on the tank cover 2. The stirring mechanism 6 stirs the materials. The eddy current and shear force generated by the rotation of the stirring mechanism 6 can effectively mix the microorganisms, nutrients, and other components in the fermentation tank, ensuring that the microorganisms can evenly contact the nutrient solution, thereby improving the fermentation efficiency. During the stirring process of the stirring mechanism 6, the tank body 1 rotates in a direction opposite to the stirring direction of the stirring mechanism 6 through the self-rotation mechanism 7. On the one hand, it can improve the cleaning effect. On the other hand, the two-way rotation can make the large-particle materials tumble in the tank body 1. At the same time, the stirring mechanism 6 can break up the agglomerated small particles and make them better distributed between the large particles, greatly improving the mixing uniformity of the materials. The exhaust pipe 5 on the tank body 1 is used for exhausting gas, and exhausts and relieves pressure in time when the pressure in the tank body 1 is too high. The fermented materials can be discharged through the discharge port 4.

[0030] Specifically, as shown in Figure 2 , Figure 3 and Figure 5 , the stirring mechanism 6 includes a motor group 61 fixed on the top of the tank cover 2. The output end of the motor group 61 is provided with a stirring shaft 62 located inside the tank body 1, and a blade 63 is arranged on the stirring shaft 62. A number of taper teeth 631 are evenly arranged along the length direction of the blade 63.

[0031] Among them, when the stirring mechanism 6 mixes materials, the motor set 61 at the top of the tank lid 2 starts and drives the blades 63 to rotate through the stirring shaft 62. The eddy current and shear force generated by the rotating blades 63 effectively mix the microorganisms, nutrients, and other components in the tank body 1, ensuring that the microorganisms can evenly contact the nutrient solution, thereby improving the fermentation efficiency. During the biological fermentation process, especially in the fermentation containing granular materials, the materials are easily formed into aggregates. The conical teeth 631 on the blades 63 can effectively break these aggregates, make the materials more evenly dispersed, increase the contact area between the microorganisms and the materials, and improve the fermentation efficiency.

[0032] Specifically, as Figures 2-4 shown, the stirring mechanism 6 further includes a scraping component 64 arranged on the blade 63. The scraping component 64 includes a connecting frame 641 connected to the blade 63. A scraping plate 642 abutted against the inner wall of the tank body 1 is arranged on the connecting frame 641. A slide rail 632 is arranged on the blade 63, and a sliding groove 643 matched with the slide rail 632 is opened on the connecting frame 641. A locking bolt 644 is arranged on the connecting frame 641. The scraping plate 642 is detachably connected to the connecting frame 641 through a connecting shaft 645. A spring 646 is sleeved on the connecting shaft 645, and a locking nut 648 abutted against the connecting frame 641 is arranged at one end of the connecting shaft 645 through a threaded end 647.

[0033] Among them, the scraping plate 642 on the connecting frame 641 abuts against the inner wall of the tank body 1. When the motor set 61 drives the stirring shaft 62 to rotate, the scraping plate 642 rotates along with the blade 63, so that the scraping plate 642 scrapes off the materials attached to the inner wall of the tank body 1, avoiding the attached materials from affecting the effective volume of the tank body 1, and at the same time avoiding problems such as excessive growth of microorganisms at the wall-hanging part and accumulation of metabolites. The scraping plate 642 can realize elastic movement with the connecting frame 641 through the spring 646 on the connecting shaft 645. The elastic action of the spring 646 can make the scraping plate 642 always closely fit the inner wall of the tank body 1. Whether the tank wall surface is flat or has slight deformation, it can effectively scrape off the attached materials, avoid the scaling and residue of materials on the tank wall, and reduce the hidden danger of microorganism breeding. When the locking bolt 644 on the connecting frame 641 is loosened, the connecting frame 641 can move along the length direction of the blade 63 under the action of the sliding groove 643 and the slide rail 632. According to the attachment situation of the materials on the tank wall and the cleaning requirements, the distance between the scraping plate 642 and the tank wall can be flexibly adjusted. For stubborn stains or relatively thick material attachment layers, the distance can be reduced to make the scraping plate 642 more closely fit the tank wall and enhance the scraping effect. For areas where the tank wall is relatively clean or only needs light cleaning, the distance can be appropriately increased to avoid the scraping plate 642 from over-scratching the tank wall and reducing the wear of the scraping plate and energy consumption.

[0034] Specifically, as Figure 1 、 Figure 6 and Figure 7As shown in the figure, the rotation mechanism 7 includes a bracket 71. On the bracket 71, a connecting rod 73 connected to the bottom of the tank body 1 is provided through a fixing plate 72. On the fixing plate 72, a driving component 74 for driving the connecting rod 73 to rotate is provided. The driving component 74 includes a driving motor 741 provided at the bottom of the fixing plate 72. A transmission belt 743 is provided on the output end of the driving motor 741 through a pulley 742, and a transmission wheel 731 matched with the transmission belt 743 is provided on the connecting rod 73.

[0035] Among them, the fixing plate 72 is provided with bearings so that the connecting rod 73 and the output shaft of the driving motor 741 can penetrate through the fixing plate 72 and rotate. When the driving motor 741 is started, the transmission belt 743 is driven to rotate by the pulley 742 on its output end. The transmission belt 743 drives the connecting rod 73 to rotate through the transmission wheel 731, and then the connecting rod 73 drives the tank body 1 to rotate on the bracket 71. When the tank body 1 rotates self - sufficiently and the scraper 642 is fixed on the stirring mechanism 6, the movement track of the scraper 642 relative to the tank wall is more complex, ensuring that the scraper 642 can cover every corner of the inner wall of the tank body 1, strengthening the cleaning effect. The self - rotation direction of the tank body 1 is opposite to that of the stirring mechanism 6, making the relative speed between the scraper 642 and the tank wall superimposed, increasing the wiping force. When scraping stubborn dirt on the tank wall, the dirt can be more effectively peeled off from the tank wall, ensuring the cleaning degree of the tank wall.

[0036] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes, should be covered within the protection scope of the present invention.
