Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of feed processing equipment, in particular to a fermentation feed solid-state fermentation premixing and scattering device. BACKGROUND

[0002] As a green and efficient feed for livestock and poultry, fermentation feed needs to accurately mix multiple solid raw materials such as corn powder, soybean meal and bran according to a specific formula during production to ensure uniformity to support subsequent inoculation of fermentation agents and fermentation process. The uniformity of premixing directly determines the quality stability and production efficiency of the final product. Currently, ordinary horizontal or vertical mixers are generally used in the premixing process of fermentation feed. However, such devices have significant defects in actual operation: the feeding process highly depends on manual operation or simple lifting devices, and cannot realize automatic process and accurate proportioning control of multiple raw materials, resulting in deviation of feeding proportion and further causing fluctuations in product quality and inconsistency between batches; the mixing structure is mostly designed with basic paddles or augers, which have limited mixing capacity when facing feed raw materials that are prone to clumping and have high adsorption, and there are obvious material retention areas in the tank, which leads to insufficient scattering and affects the fermentation efficiency; the addition of liquid components such as fermentation agents or water is usually through manual spraying or fixed pipeline injection, which lacks uniform atomization mechanism and is prone to form local over-wet areas and induce material clumping; at the same time, residual materials are easily attached to the inner wall of the mixing tank, which not only increases raw material loss but also complicates cleaning and maintenance, further interfering with the mixing accuracy and hygiene standards of subsequent batches.

Meanwhile, in the description of the application, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0023] The conventional existing fermentation feed premixing equipment is difficult to realize the automation of multiple raw materials, accurate proportioning and feeding during the feeding process, which is easy to cause formula error. The mixing effect of the stirring device is limited, there are mixing dead angles, the material is not fully scattered, which leads to poor premixing uniformity. The liquid additive is difficult to be evenly atomized and distributed, which is easy to cause local over-wetting and caking. The material is easy to stick to the inner wall of the mixing tank, which causes waste of raw materials and inconvenience of cleaning.

[0024] Please refer to Figures 1 to 6To address this, the present application proposes a fermentation feed solid-state fermentation premix scattering device, which includes a support box body 1 with an open upper surface, a mixing tank body 2 arranged inside the support box body 1, a stirring and scattering member 3 arranged inside the mixing tank body 2 for mixing and scattering operation, support rods 11 arranged around the upper surface of the support box body 1, a support frame 12 erected on the support rods 11, a weighing sensor 13 arranged around the upper surface of the support frame 12, a weighing member 4 arranged on the weighing sensor 13 and corresponding to the feed inlet of the mixing tank body 2, a support frame 5 arranged behind the support box body 1, a feeding member 6 arranged on the support frame 5 for feeding the weighing member 4, and a batching mechanism 7 arranged behind the support frame 5 to realize automatic batching, accurate weighing and efficient mixing and scattering of fermentation feed raw materials, thereby overcoming the shortcomings of the prior art.

[0025] The support box body 1 is connected to a discharge hopper 10 arranged for discharging the mixed fermentation feed.

[0032] Weighing member: arranged on the weighing sensor, it is used to receive raw materials from the feeding member and cooperate with the weighing sensor to realize accurate weighing of raw materials. The discharge port of the weighing member is arranged corresponding to the feed inlet of the mixing tank body, ensuring that the weighed material can be accurately fed into the mixing tank body.

[0033] Support frame: arranged behind the support box body, it is used to support the feeding member and the batching mechanism to form a complete feeding and batching system.

[0034] The feeding device is arranged on the support frame and used to deliver the raw materials in the ingredient mechanism to the weighing device, so as to realize automatic feeding of the raw materials.

[0035] The ingredient mechanism is arranged at the rear of the support frame and used to store different kinds of fermented feed raw materials and to preliminarily distribute the materials according to a preset formula.

[0036] The device of the embodiment comprises a support box with an open upper surface. The support box can be composed of metal plates welded together, and the open upper surface facilitates installation, maintenance and material observation of the internal components.

[0037] The mixing tank is arranged inside the support box. The mixing tank can have a cylindrical or U-shaped groove structure, and is usually made of stainless steel to ensure hygiene and corrosion resistance when in contact with the fermented feed raw materials. The mixing tank is fixed inside the support box by welding or bolt connection.

[0038] The mixing tank is provided with a stirring and dispersing device for realizing mixing and dispersing operation. The stirring and dispersing device can be composed of a central shaft and a plurality of stirring blades fixed thereon. The central shaft is driven to rotate by external power, and the blades are used to turn and mix the materials in the tank.

[0039] The support rods are arranged around the upper surface of the support box. The support rods can be made of square steel or round steel and are vertically fixed at the edges of the support box by welding or bolt connection.

[0040] A support frame is arranged on the support rods. The support frame can be composed of profiled steel and have a rectangular or square structure to provide stable support for the weighing system above.

[0041] The weighing sensors are arranged around the upper surface of the support frame. The weighing sensors can be pressure sensors or tension sensors and are fixed at corresponding positions of the support frame by bolts to sense the weight change of the weighing device above.

[0042] The weighing device is arranged on the weighing sensors and corresponds to the feeding port of the mixing tank. The weighing device can be a hopper structure, and the bottom of the hopper is provided with a manually or electrically controlled gate for feeding the materials into the mixing tank after weighing is completed.

[0043] The support frame is arranged at the rear of the support box. The support frame can be built of steel structure, and the height and structure design meet the installation requirements of the feeding device and the ingredient mechanism.

[0044] The feeding device is arranged on the support frame and used to deliver the raw materials in the ingredient mechanism to the weighing device, so as to realize automatic feeding of the raw materials.

[0045] The support frame rear is provided with a batching mechanism. The batching mechanism can be composed of multiple independent hoppers, each hopper bottom is provided with a manually or electrically controlled discharge port for storing different kinds of fermented feed raw materials and distributing materials according to the formula requirements.

[0046] The fermentation feed solid-state fermentation premixing and dispersing equipment provided in the application realizes automatic batching, accurate weighing and efficient feeding of fermented feed raw materials by integrating the batching mechanism, the feeding member, the weighing member and the mixing tank, effectively avoids the formula error problem caused by traditional manual feeding and simple elevator. At the same time, the stirring and dispersing member arranged in the mixing tank can fully mix and effectively disperse the solid raw materials, improve the uniformity of premixing, and lay a foundation for the subsequent fermentation process.

[0047] In some embodiments of the application described above, a fermentation feed solid-state fermentation premixing and dispersing equipment is provided, which includes a stirring and dispersing member for mixing and dispersing, a weighing member and a feeding member for feeding, and is provided with a batching mechanism. However, in actual operation, if the batching mechanism fails to effectively organize and store multiple fermented feed raw materials, it may lead to low efficiency of the batching process, confusion of raw materials or inaccurate batching, which is difficult to meet the demand of accurate proportioning of multiple raw materials for solid-state fermentation.

[0048] Please continue to refer to Figures 1 to 4 As shown in the figure, for this purpose, the application further provides that the batching mechanism 7 comprises a support platform 71, a support column 72 is arranged behind the support frame 5, the support platform 71 is arranged on the support column 72, and a batching bin 73 is embedded on the support platform 71, and a plurality of batching grooves 74 for placing different fermented feed raw materials are arranged at equal intervals in the batching bin 73.

[0049] Specifically, the support platform of the batching mechanism is a flat or frame structure that provides the structural foundation for the entire batching system. It is typically made of high-strength materials such as stainless steel or carbon steel to ensure that it can withstand the weight of the batching bin and its internal raw materials, and maintain stability over a long period of use. Its design should take into account load-bearing, corrosion resistance, and integration with the overall equipment. The support columns are vertical structural components used to elevate the support platform to a predetermined height. These support columns are usually composed of metal profiles such as square tubes or round tubes, which are firmly fixed to the back of the support frame through welding, bolting, or other means. The height of the support column should be designed to match the working height of the feeding component to ensure smooth transfer of raw materials from the batching bin to the feeding component. The support platform is stably arranged on the top of the support column, forming a high-level working area that facilitates subsequent raw material feeding and conveying. The batching bin is the main container for storing multiple fermented feed raw materials. The batching bin is usually designed in an integrated manner, and its material should have good corrosion resistance and easy cleaning to adapt to the characteristics of fermented feed raw materials. The batching bin is installed in the "embedded" manner on the support platform, which means that the bottom or part of the structure of the batching bin is embedded or fixed in the opening or frame of the support platform, thereby increasing the overall stability and structural compactness, and effectively preventing the displacement of the batching bin during use. The batching tank is a sub-container inside the batching bin used to separate and store different types of fermented feed raw materials. These batching tanks are arranged equidistantly along the length or width of the batching bin, ensuring that each type of raw material has an independent storage space, avoiding mixing between different raw materials. The design of the batching tank should facilitate the filling and removal of raw materials, and the capacity or number of batching tanks can be adjusted according to actual needs. The equidistant arrangement helps to standardize the design and operation of subsequent automated material removal or conveying mechanisms.

[0050] Through the above technical solution, the batching mechanism is specifically designed to include a support platform, support columns, a batching bin, and equidistantly arranged batching tanks inside the batching bin. This structure allows different types of fermented feed raw materials to be orderly packed and stored in separate batching tanks, effectively preventing confusion and cross-contamination between raw materials. The support platform and support columns provide stable support for the batching bin, ensuring the stability and reliability of the entire batching mechanism. The embedding of the batching bin and the equidistant arrangement of the batching tanks not only optimize space utilization, but more importantly, provide standardized interfaces and convenient conditions for subsequent automated batching and feeding operations, significantly improving the accuracy and efficiency of multi-component fermented feed raw material batching, thereby ensuring the quality of fermented feed and the smooth progress of the production process.

[0051] In some embodiments of the present application, a batching tank for placing different fermented feed raw materials and a feeding member for realizing the feeding of the weighing member are proposed. However, in actual operation, how to ensure that multiple fermented feed raw materials can be efficiently and accurately conveyed from the respective batching tanks to the weighing member to meet the batching accuracy and efficiency requirements of the premixing and scattering is a problem to be solved.

[0052] To this end, the feeding member 6 specifically includes a feeding conveyor belt 61. The feeding member 6 includes the feeding conveyor belt 61, and the support frame 5 is provided with L-shaped support plates 62 at both left and right ends. A plurality of feeding conveyor belts 61 corresponding to the batching tanks 74 are arranged at equal distances between the L-shaped support plates 62 at both left and right ends, and the discharge outlets of the batching tanks 74 are arranged corresponding to the feeding inlets of the feeding conveyor belts 61.

[0053] The support frame is provided with L-shaped support plates at both left and right ends, which provide a stable mounting basis for the feeding conveyor belt. The material of the L-shaped support plates is usually high-strength metal, such as stainless steel or carbon steel, to ensure structural stability and durability, and effectively disperse the weight of the feeding conveyor belt and the materials carried thereby. A plurality of feeding conveyor belts corresponding to the batching tanks are arranged at equal distances between the L-shaped support plates at both left and right ends. This multi-channel design aims to realize parallel or sequential conveying of multiple fermented feed raw materials in different batching tanks, avoiding cross contamination between different raw materials, and facilitating system integration and control. The width and length of each feeding conveyor belt can be customized according to the size of the corresponding batching tank and the required conveying amount, and the conveyor belt body can be made of PVC, PU, or rubber, etc. to adapt to the characteristics of different fermented feed raw materials, such as viscosity, particle size, etc. Meanwhile, the discharge outlets of the batching tanks are arranged corresponding to the feeding inlets of the feeding conveyor belts, which directly interfaces to minimize material spillage and waste during transfer, ensuring batching accuracy, simplifying equipment structure, and reducing maintenance difficulty. A deflector or buffer structure can be further arranged at the feeding inlet to ensure smooth entry of the material into the conveyor belt.

[0054] By the above technical solution, the feeding member is specifically implemented as a plurality of feeding conveyors, which are accurately corresponding to the discharge openings of the ingredient tanks, effectively solving the problem of efficient and accurate conveying of various fermented feed raw materials from the ingredient tanks to the weighing member. Each ingredient tank is equipped with an independent feeding conveyor, ensuring the independence of different raw materials during conveying, avoiding cross contamination, and thus ensuring the accuracy of the ingredients. At the same time, this multi-channel parallel or sequential conveying design significantly improves the conveying efficiency of the materials and shortens the ingredient time. In combination with the plurality of ingredient tanks of the ingredient mechanism, the feeding system can realize the automatic, accurate and efficient conveying of various fermented feed raw materials, providing reliable material guarantee for subsequent weighing and mixing and scattering operations, thereby improving the automation level and production efficiency of the entire fermented feed solid-state fermentation premixing and scattering equipment.

[0055] In some embodiments of the present application described above, it is proposed to convey the fermented feed raw materials in different ingredient tanks to the weighing member for weighing through a plurality of feeding conveyors. However, in actual operation, due to the gaps between the feeding conveyors and between the conveyors and the weighing member, material may be spilled during conveying, causing material loss and environmental pollution; at the same time, there is a risk of cross contamination between different materials, affecting the accuracy of the ingredients and the quality of the feed; in addition, after the material is unloaded from the conveyor, it may not be accurately and centrally fed into the weighing member, affecting the weighing efficiency and accuracy.

[0056] Please continue to refer to Figures 1 to 3 As shown, the present application further proposes that fixed blocks 63 are arranged on the middle part of the upper surface of the support plates at the left and right ends of the plurality of feeding conveyors 61, fixed rods 64 are arranged between the fixed blocks 63 at the left and right ends, and separation protection plates 65 are arranged at the left and right ends of the fixed rods 64. An inclined guide chute 66 corresponding to the weighing member 4 is arranged at the discharge opening of the plurality of feeding conveyors 61.

[0057] Specifically, the fixed block is a structural member for fixing and supporting other components, which functions to provide a stable connection point to ensure the secure installation of the fixed rod and the partition guard plate. The fixed block can be fixed in the middle of the upper surface of the support plate by welding, bolting, or other methods, and can be made of high-strength metal such as stainless steel or carbon steel to withstand the corresponding load and vibration. The fixed rod, as a rod-shaped structure connecting two fixed blocks, functions as a mounting base for the partition guard plate and provides stability to the overall structure. The fixed rod can be a solid or hollow rod connected to the fixed blocks by bolting or welding, and its length should match the width and spacing of the upper conveying belt to ensure that the partition guard plate can effectively cover it. The partition guard plate is a plate-shaped structure arranged on the fixed rod to separate the materials between different upper conveying belts, which functions to prevent the materials transported by different ingredient tanks from being confused or spilled onto adjacent conveying belt areas during the conveying process, ensuring the purity of the materials and the accuracy of the ingredients. The partition guard plate can be made of metal plates, high-molecular material plates, etc., and can be fixed on the fixed rod by buckling, bolting, or welding, etc. Its height should be sufficient to effectively block the material splashing and not affect the normal operation of the conveying belt. The inclined guide hopper is a funnel-shaped or channel-shaped structure with a certain inclination angle, arranged at the discharge port, which functions to concentrate and guide the materials discharged from the upper conveying belt to the inlet of the weighing member, reducing material spillage and improving feeding efficiency and weighing accuracy. The inclined guide hopper is usually made of metal plates (such as stainless steel) by welding or bending, and its inclination angle and outlet size need to be optimized according to the flowability of the material, the discharge speed of the conveying belt, and the size of the inlet of the weighing member. The surface can be polished or coated with anti-sticking material to ensure smooth sliding of the material.

[0058] By the above technical solution, the fixed block, fixed rod and partition guard plate are arranged between multiple upper conveying belts, effectively forming a physical isolation, thereby avoiding the spillage and cross-contamination of different fermented feed raw materials during the conveying process, ensuring the accuracy of the ingredients and the quality of the feed. At the same time, the inclined guide hopper corresponding to the weighing member is arranged at the discharge port of the multiple upper conveying belts, which can accurately and centrally guide the materials discharged from the conveying belt to the inlet of the weighing member, greatly reducing the loss of materials during the transfer process, improving the feeding efficiency and weighing accuracy, and ensuring the smoothness and reliability of the entire premixing and scattering process.

[0059] In some embodiments of the present application, a fermented feed solid-state fermentation premixing and scattering device is provided, wherein a weighing member is arranged on the weighing sensor for weighing the fermented feed raw materials. However, after weighing, how to accurately and controllably put the weighed materials into the mixing tank to avoid material spillage and ensure the feeding accuracy is a key link to realize automatic ingredient mixing.

[0060] Please continue to see Figures 1 to 3As shown, for this, the application further puts forward the specific structure of the weighing member, the weighing member 4 includes a fixed frame 41, the weighing sensor 13 is provided with the fixed frame 41, the lower surface of the fixed frame 41 is connected with a lower hopper 42, and the lower hopper 42 is correspondingly arranged with the feed inlet of the mixing tank body 2, the lower hopper 42 is provided with a U-shaped support rod 43, the middle part of the crossbar of the U-shaped support rod 43 is embedded with a multi-section telescopic cylinder 44, and the telescopic rod end of the multi-section telescopic cylinder 44 is provided with a openable and closable plate 45 for opening and closing the lower hopper 42.

[0061] Specifically, the fixed frame is the main structure of the weighing member, which provides a stable support and mounting base for the entire weighing and discharging assembly. It is usually made of metal profiles (such as square steel, channel steel) welded or bolted, with sufficient strength and rigidity to withstand the weight of the material and the dynamic load of the subsequent discharging mechanism. The fixed frame is stably arranged on the weighing sensor, ensuring that the weighing sensor can accurately perceive the weight of all components and materials on it.

[0062] The lower hopper is a funnel-shaped or conical structure, which mainly functions to collect and guide the weighed material from below the fixed frame to the feed inlet of the mixing tank body. Its large-up-small structure design helps prevent material from scattering during the falling process, ensuring that the material can be concentrated and smoothly enter the mixing tank body. The outlet of the lower hopper precisely corresponds to the feed inlet of the mixing tank body to minimize material loss during transfer.

[0063] The U-shaped support rod is arranged at a suitable position of the lower hopper, which provides a stable mounting point and support structure for the multi-section telescopic cylinder. The U-shaped design of the support rod can effectively fix the cylinder and allow the telescopic rod of the cylinder to move linearly below the lower hopper, thereby driving the openable and closable plate.

[0064] The multi-section telescopic cylinder is a pneumatic actuator with multiple telescopic rods, characterized by achieving a longer stroke in a smaller installation space. Here, it is embedded in the middle part of the crossbar of the U-shaped support rod and driven by air pressure to perform reciprocating motion. The telescopic action of the cylinder is the key power source for opening and closing the lower hopper, and the stroke length is sufficient to ensure that the openable and closable plate can completely open or close the outlet of the lower hopper.

[0065] The openable and closable plate is a movable plate structure that functions as an outlet valve of the lower hopper to control the discharge of material. When the telescopic rod of the multi-section telescopic cylinder extends, the openable and closable plate is driven to the closed position to prevent material from falling; when the telescopic rod retracts, the openable and closable plate is driven to the open position to allow material to enter the mixing tank body from the lower hopper. The openable and closable plate is usually made of wear-resistant and corrosion-resistant materials to adapt to the characteristics of fermented feed raw materials.

[0066] By the above technical solution, the weighing member is specifically designed as a structure comprising a fixed frame, a lower hopper, a U-shaped support rod, a multi-section telescopic cylinder, and an openable and closable plate. The fixed frame is arranged on the weighing sensor, ensuring the stability and accuracy of the weighing process. The lower hopper connected to the lower surface of the fixed frame can effectively collect and guide the weighed material and accurately correspond to the feed inlet of the mixing tank body, thereby avoiding the spillage and waste of the material during feeding. More importantly, by arranging the U-shaped support rod on the lower hopper and embedding the multi-section telescopic cylinder, and driving the openable and closable plate by the telescopic rod end, the accurate control of the lower hopper outlet is realized. When feeding is needed, the multi-section telescopic cylinder drives the openable and closable plate to open, and the material smoothly enters the mixing tank body; after the feeding is completed, the openable and closable plate is closed, effectively cutting off the material flow. This design makes the feeding process of the weighed material highly controllable and automated, significantly improves the accuracy and efficiency of feeding, reduces manual intervention, and ensures the accuracy of the fermented feed formula, thereby providing a stable material basis for subsequent mixing and scattering operations.

[0067] In the fermentation feed solid-state fermentation pre-mixing and scattering device, the stirring and scattering member in the mixing tank body is the key to realize uniform mixing and effective scattering of the material. However, the fermentation feed raw material usually has certain viscosity and agglomeration. If the structure of the stirring and scattering member is not reasonably designed, it may cause uneven mixing and incomplete scattering of the material, and even dead angles or caking phenomenon, thereby affecting the fermentation effect and product quality.

[0068] Please continue to read Figures 1 to 6 As shown in the figure, for this purpose, the present application further proposes a stirring and scattering member 3, which comprises a driving motor 32, a rotating shaft 33, and a plurality of scattering rods 34. The support box body 1 is provided with support blocks 31 on the upper surface of the left and right ends, one of which is provided with the driving motor 32, the output end of the driving motor 32 is connected with the rotating shaft 33, the rotating shaft 33 is horizontally arranged, and its two ends are rotatably supported on the side wall of the mixing tank body 2 through bearings. A plurality of groups of stirring rods 35 are arranged on the rotating shaft 33 along the axial direction at equal distances, each group of stirring rods 35 comprises two rod bodies extending radially and arranged in parallel upward and downward. The ends of each group of stirring rods 35 are jointly connected to an arc-shaped stirring rod 36, and a plurality of connecting rods 37 are arranged at equal distances inside the same arc-shaped stirring rod 36 and connected between the upper and lower two stirring rods 35, and a plurality of scattering rods 34 are vertically arranged on each connecting rod 37.

[0069] Specifically, the drive motor is the core component that provides power output for the entire stirring and dispersing system. It usually adopts an alternating current motor or a direct current motor, which converts high-speed rotating electrical energy into low-speed high-torque mechanical energy through a reduction mechanism to drive the rotating shaft to rotate, thereby driving the stirring and dispersing member to mix and disperse the material in the mixing tank. The power and speed of the drive motor can be selected and adjusted according to the viscosity of the fermented feed, the yield requirement and the mixing and dispersing effect.

[0070] The rotating shaft is a transmission component connecting the drive motor and the stirring and dispersing member, which is horizontally arranged inside the mixing tank and is supported by bearings to ensure smooth rotation. The material of the rotating shaft is usually high-strength stainless steel to resist the corrosiveness of fermented feed and withstand the torque and impact force during stirring. The design length and diameter of the rotating shaft need to match the size of the mixing tank and the layout of the stirring and dispersing member to ensure the stirring coverage and intensity.

[0071] The plurality of dispersing rods are the key components that directly act on the fermented feed material to achieve its breaking and dispersing. These dispersing rods are usually rod-shaped or blade-shaped, which exert shearing, impact and friction force on the material through high-speed rotation or reciprocating motion, thereby effectively breaking the material clumps, refining the particles and uniformly distributing them. The material of the dispersing rods can be alloy steel or composite material that is wear-resistant and corrosion-resistant, and the number, length, cross-sectional shape and arrangement of the dispersing rods can be optimized according to the characteristics of the material and the dispersing requirements.

[0072] The support block is a structural member for fixing the drive motor and supporting the rotating shaft. They are usually made of high-strength metal materials and firmly installed on the left and right ends of the upper surface of the support box. The design of the support block needs to have sufficient rigidity and stability to withstand the vibration generated by the drive motor in operation and the reaction force received by the rotating shaft during stirring, ensuring the stable operation of the entire stirring and dispersing system.

[0073] The plurality of stirring rods are structures connecting the rotating shaft and the arc-shaped stirring rod and the connecting rod, which are arranged equidistantly along the axial direction of the rotating shaft to form multiple stirring units. Each group of stirring rods consists of two rod bodies that extend radially and are arranged in parallel vertically. This structure design helps to fully turn and mix the material in the radial direction. The length and spacing of the stirring rods need to be reasonably configured according to the diameter of the mixing tank and the filling height of the material to ensure that the stirring covers the entire material layer.

[0074] The arc-shaped stirring rod connects the end of each group of stirring rods to form an arc-shaped structure around the rotating shaft. Its curvature is designed to match the curvature of the inner wall of the mixing tank, which helps to scrape the material from the tank wall and push it to the center during stirring, reducing the adhesion and accumulation of the material on the tank wall, and enhancing the overall circulation of the material. The arrangement of the arc-shaped stirring rod also provides support and connection points for the connecting rod and the dispersing rod.

[0075] The plurality of connecting rods are located inside the arc-shaped stirring rod and are connected equidistantly between the upper and lower stirring rods. These connecting rods serve as a framework, further enhancing the overall structural strength of the stirring and dispersing member, and providing a vertical mounting base for the dispersing rod. Through the arrangement of the connecting rods, the dispersing rod can maintain a stable position and posture during stirring, thereby achieving effective dispersing of the material.

[0076] The dispersing rod is vertically arranged on each connecting rod. This vertical arrangement allows the dispersing rod to cut, impact, and rub the material in a direction perpendicular to the flow direction of the material when the rotating shaft rotates. This multi-point and multi-directional dispersing action can more effectively break up the clumps in the fermented feed, improving the uniformity and dispersibility of the material and avoiding the formation of dead corners or adhesion of the material during stirring.

[0077] Through the above technical solutions, the driving motor provides stable and reliable power for the stirring and dispersing member, driving the rotating shaft to rotate horizontally. The plurality of stirring rods arranged equidistantly along the axis of the rotating shaft, each consisting of two radially extending and vertically parallel rod bodies, can fully flip and mix the material in the mixing tank. The arc-shaped stirring rod connected to the end of each stirring rod has an arc that matches the inner wall of the mixing tank, which helps to scrape the material off the tank wall and push it towards the center, effectively reducing material adhesion and dead corners. More importantly, the plurality of connecting rods located inside the arc-shaped stirring rod and connected between the upper and lower stirring rods, and the plurality of dispersing rods vertically arranged on each connecting rod, can produce multi-point and multi-directional shearing, impact, and rubbing action on the fermented feed material when the rotating shaft rotates. This ingenious structural design not only allows the material to be fully flipped macroscopically, but also effectively broken and dispersed at the micro level during mixing, thereby completely solving the technical problems of fermented feed with high viscosity and easy agglomeration, leading to uneven mixing and incomplete dispersing, and significantly improving the mixing uniformity and dispersing effect of fermented feed, providing a better raw material basis for the subsequent fermentation process.

[0078] In some embodiments of the present application, a device including a mixing tank and a stirring and dispersing member for achieving mixing and dispersing operation is proposed. However, in the actual process of solid-state fermentation of fermented feed, due to the viscosity of the material or the influence of the internal structure of the mixing tank, part of the material may adhere to the inner wall of the mixing tank, resulting in uneven mixing, material residue, and thus affecting the fermentation effect and the cleaning efficiency of the equipment. This material adhesion problem not only causes waste of raw materials, but also increases the difficulty of subsequent cleaning and maintenance, reducing the overall operating efficiency of the equipment.

[0079] Please continue to refer to Figure 5 and Figure 6As shown, in this regard, the application further proposes that a connecting plate 38 be horizontally arranged at the upper end position between every two adjacent arc-shaped stirring rods 36, with a scraper telescopic cylinder 39 vertically embedded in the middle of the connecting plate 38, the telescopic rod of the scraper telescopic cylinder 39 extending downward, and the end thereof being connected with an arc-shaped rubber scraper 30 that is adapted to the curvature of the inner wall of the mixing tank 2.

[0080] The connecting plate serves as the mounting base of the scraper telescopic cylinder, which is horizontally arranged between adjacent arc-shaped stirring rods, ensuring that the scraper telescopic cylinder can be stably mounted and perform telescopic movement in the vertical direction. The connecting plate is usually made of a metal material with sufficient strength and rigidity, such as a stainless steel plate, which is firmly fixed to the arc-shaped stirring rod through welding or bolt connection, etc., to withstand the reaction force generated during the operation of the scraper telescopic cylinder.

[0081] The scraper telescopic cylinder is an actuator that drives the telescopic rod to perform linear reciprocating motion through compressed air. Its main function is to provide power to enable the arc-shaped rubber scraper to periodically contact and scrape the inner wall of the mixing tank. The cylinder can be a single-acting or double-acting cylinder, and its stroke length and thrust are precisely selected and configured according to the height of the mixing tank and the force required for scraping, to ensure that the scraper can cover the effective area of the inner wall of the mixing tank and effectively remove the attached materials. The installation method of the cylinder should ensure its stability in the vertical direction to avoid shaking during operation.

[0082] The telescopic rod is the core component of the scraper telescopic cylinder, responsible for transmitting the linear motion of the cylinder to the arc-shaped rubber scraper. It is usually made of high-strength metal material, with the surface being precisely machined and hardened to improve its wear resistance and corrosion resistance, ensuring good performance and precision in long-term use.

[0083] The arc-shaped rubber scraper is the component that directly contacts the inner wall of the mixing tank, and the key to its design is that its curvature is adapted to the curvature of the inner wall of the mixing tank. The selection of rubber material is crucial, which needs to have excellent wear resistance, corrosion resistance (to adapt to the acid and alkali environment of fermented feed) and good elasticity, so as to effectively remove materials during scraping without damaging the tank. The scraper is firmly connected to the end of the telescopic rod through bolting or bonding, etc., to ensure stable and reliable scraping operation under the drive of the telescopic cylinder.

[0084] Through the technical scheme, when the stirring and dispersing piece is used for mixing and dispersing, the scraper telescopic cylinder can periodically drive the arc-shaped rubber scraper to extend downward, so that the arc-shaped rubber scraper is tightly attached to and scraped against the inner wall of the mixing tank. This effectively solves the problem of material adhering to the tank wall during mixing, ensuring that the material inside the mixing tank can be fully turned over and mixed, avoiding the residue and caking of local material. At the same time, the scraper design enables the inner wall of the mixing tank to be effectively cleaned after the mixing operation is completed, significantly reducing the labor intensity and time of manual cleaning, and improving the cleaning efficiency and turnover rate of the equipment. Overall, the scraper structure cooperates with the stirring and dispersing piece to not only improve the uniformity and thoroughness of the fermentation feed premixing, but also optimize the operation and maintenance experience of the equipment, thereby ensuring the quality and production efficiency of the fermentation feed.

[0085] In some embodiments of the present application, a device for solid-state fermentation premixing and dispersing of fermentation feed is provided, which uses a stirring and dispersing piece to mechanically mix and disperse the material. However, in the preparation process of fermentation feed, it is often necessary to add liquid ingredients (such as water, microbial liquid, nutrient liquid, etc.) to adjust the moisture of the material, activate the microorganisms, or supplement nutrients. If only relying on traditional mechanical stirring, the liquid ingredients may be difficult to uniformly penetrate and distribute into the solid material, resulting in uneven mixing, local over-wetting or over-drying, and thus affecting the fermentation effect and product quality.

[0086] Please continue to refer to Figure 5 and Figure 6 As shown, the present application further provides that the rotating shaft 33 is a hollow shaft, and a water outlet pipe (not shown) is embedded inside the rotating shaft 33. A plurality of atomizing spray heads 8 are connected to the water outlet pipe at equal intervals along the length direction of the water outlet pipe, and the spray nozzles of the atomizing spray heads 8 face the inside of the mixing tank 2. One end of the water outlet pipe is connected to a water inlet pipe 81 that penetrates through the rotating shaft 33 through a rotary joint.

[0087] Specifically, the rotating shaft is designed as a hollow structure, and a through channel is formed inside the rotating shaft. This design enables the rotating shaft to accommodate other internal components, such as a pipe for conveying liquid, while performing the stirring and dispersing function, thereby realizing multifunctional integration. The material of the hollow shaft is usually selected from high-strength, corrosion-resistant metals to ensure its stability and service life in high-speed rotation and material contact environment.

[0088] Inside the hollow rotating shaft, a water outlet pipe is embedded. The water outlet pipe is used to transport externally supplied liquid additives to the inside of the mixing tank. The material of the water outlet pipe can be selected from stainless steel or corrosion-resistant plastic to adapt to the properties of different liquid additives and ensure the cleanliness of the transportation process. The embedding method can use a fixed bracket or a seal to ensure the relative stability of the water outlet pipe during rotation of the rotating shaft.

[0089] The water outlet pipe is uniformly distributed and connected with multiple atomizing spray heads along its axial direction. The atomizing spray heads convert the delivered liquid additives into fine mist particles to increase the surface area of the liquid and improve its dispersion and penetration in the solid material. The atomizing spray heads can use pressure nozzles, centrifugal nozzles, or ultrasonic nozzles, etc., and their spray angles and flow rates can be selected and adjusted according to actual needs to ensure that the spray range covers the entire interior of the mixing tank, achieving uniform distribution of the liquid additives.

[0090] The spray nozzles of the atomizing spray heads are precisely oriented towards the material inside the mixing tank. This design ensures that the sprayed liquid mist directly acts on the solid fermentation feedstock being mixed, avoiding liquid spraying onto the tank wall or other non-target areas, thereby maximizing the utilization efficiency and mixing uniformity of the liquid additives.

[0091] One end of the water outlet pipe is connected to the water inlet pipe passing through the rotating shaft through a rotary joint. The rotary joint is a specially designed sealing device that allows liquid or gas to be continuously and leak-free transported from a fixed pipe (water inlet pipe) to a rotating component (water outlet pipe), maintaining the flow passage unobstructed even when the rotating shaft is rotating at high speed. The water inlet pipe is responsible for continuously delivering external liquid additives to the rotary joint.

[0092] Through the above technical solutions, the liquid additive spraying function is integrated into the rotating shaft of the stirring and dispersing device, realizing real-time, uniform, and fine addition of liquid components during the solid fermentation feed premixing and dispersing process. When the driving motor rotates the rotating shaft, the stirring and dispersing device mechanically mixes the material while the liquid additives are delivered to the atomizing spray heads through the water inlet pipe, rotary joint, and water outlet pipe, and are uniformly sprayed in fine mist onto the material inside the mixing tank. This internal spraying method avoids the problems of uneven liquid distribution, local accumulation, or splashing that may occur with traditional external spraying. The atomizing spray heads atomize the liquid into fine particles, greatly increasing the contact area between the liquid and the solid material, promoting rapid penetration and uniform adsorption of the liquid, thereby effectively adjusting the moisture of the material, activating the fermentation bacteria, and ensuring balanced distribution of nutritional components. This not only significantly improves the mixing uniformity and fermentation efficiency of the fermented feed, but also helps to improve the quality and stability of the final product.

[0093] Although the above-mentioned fermentation feed solid-state fermentation premixing and dispersing device provides a complete physical structure, including a batching mechanism for batching, a weighing member for weighing and feeding, and a stirring and dispersing member for mixing and dispersing, in order to achieve accurate material batching, efficient feeding operation, and uniform and stable mixing process, a large amount of monitoring and manual adjustment by an operator is still required. This manual operation not only is inefficient, prone to errors, and difficult to ensure consistency of different batches of products, but also significantly increases the complexity of operation when dealing with multiple raw materials and liquid additives, thereby affecting the overall production quality and efficiency of the fermentation feed.

[0094] To this end, the present application further provides that the device further comprises a control system electrically connected with each weighing sensor, the driving device of each feeding conveyor belt, the driving motor, the multi-section telescopic cylinder, the scraper telescopic cylinder, and the liquid flow control valve connected to the water inlet pipe, for realizing automatic batching, weighing, feeding, mixing and dispersing, and automatic control of liquid additive spraying according to the formula.

[0095] Specifically, the control system is the core of the device automation operation, which can adopt the form of industrial programmable logic controller (PLC), distributed control system (DCS) or industrial computer (IPC) etc. The system is responsible for receiving data from various sensors, and sending control instructions to the actuator according to the preset program and formula, to coordinate the collaborative work of each component of the device. Its internal usually contains data acquisition module, processing module, storage module and communication module, which can monitor the device state in real time, analyze data, and adjust the control strategy according to the feedback information. The control system establishes connection with each weighing sensor through electrical signal, and obtains the electrical signal output by the weighing sensor in real time. These signals are converted into accurate weight data after processing. Through the monitoring of these weight data, the control system can accurately judge the weight of the current material, so as to realize the accurate control of the batching and feeding process, and ensure that the addition amount of each raw material meets the preset formula requirements. At the same time, the control system is electrically connected with the driving device (such as motor driver) of each feeding conveyor belt, which can accurately control the start, stop and running speed of each feeding conveyor belt. By controlling the running state of the conveyor belt, the accurate conveying of raw materials in different batching tanks can be realized, and the specified amount of raw materials can be sent to the weighing part at the specified time. In addition, the control system is electrically connected with the driving motor of the stirring and scattering part, which can control the start-stop, speed and running time of the driving motor. Through the accurate control of the driving motor, the effective management of the mixing and scattering process can be realized, and the material can be fully and uniformly mixed in the mixing tank body to achieve the ideal scattering effect. In order to realize accurate feeding and cleaning, the control system is also electrically connected with multiple telescopic cylinders, which can control the extension and retraction of the cylinder to accurately control the opening and closing of the opening and closing plate of the lower hopper, realize the accurate control of the material feeding process, and avoid material overflow or feeding delay. Similarly, the control system is electrically connected with the scraper telescopic cylinder, which can control the extension and retraction of the cylinder to drive the arc-shaped rubber scraper to scrape and clean the inner wall of the mixing tank, effectively prevent the material from adhering, keep the inner wall of the mixing tank clean, and reduce cross contamination. For the spraying of liquid additives, the control system is electrically connected with the liquid flow control valve connected to the water inlet pipe, which can accurately control the opening of the liquid flow control valve to adjust the flow of liquid additives. Through the accurate control of the liquid flow, the on-demand and accurate spraying of liquid additives can be realized, which can ensure the sufficient mixing of liquid additives and solid raw materials, and improve the utilization rate and mixing uniformity of additives. Automation control means that the device can automatically complete the whole production process from raw material selection, accurate weighing, orderly feeding, efficient mixing and scattering to accurate spraying of liquid additives according to the preset production formula without human intervention or with only a small amount of human monitoring. This includes sequence control, time control, quantity control, state monitoring and exception handling of each link.

[0096] By the above technical scheme, the key sensors and actuators such as each weighing sensor, driving device of each feeding conveyor belt, driving motor, multi-section telescopic cylinder, scraper telescopic cylinder, and liquid flow control valve connected to the water inlet pipe in the device are integrated and managed. The control system can monitor the material weight in real time, control material conveying, adjust stirring intensity, accurately control feeding and cleaning action, and accurately spray liquid additives. This integrated automatic control enables the entire fermentation feed premixing and scattering process to strictly follow the preset formula, realizing automatic batching, accurate weighing, orderly feeding, efficient mixing and scattering of raw materials, and accurate spraying of liquid additives. This significantly improves the accuracy and consistency of batching, effectively avoids errors and labor intensity caused by manual operation, ensures the uniformity and efficiency of the mixing process, and greatly improves the production quality and overall production efficiency of the fermentation feed, providing a stable and reliable premixing basis for the subsequent fermentation process.

[0097] The above technical scheme will be further described through a more specific example as follows: In a fermentation feed production workshop, a batch of high-quality fermentation feed needs to be produced according to a specific formula. Traditional manual batching and simple stirring methods have problems such as inaccurate batching, uneven mixing, uneven distribution of liquid additives, and tank sticking. This device realizes automation and efficiency of the fermentation feed premixing and scattering process through integrated design.

[0098] Firstly, the user inputs the preset fermentation feed formula through the control system. The formula includes the accurate proportions of multiple solid raw materials such as corn meal, soybean meal, and bran. The support platform of the batching mechanism is embedded with multiple batching bins, and each batching bin is equipped with batching slots for placing different fermentation feed raw materials at equal intervals. For example, one batching slot is for corn meal, another is for soybean meal, and the third is for bran. When the system starts, the feeding part starts working. The feeding part includes multiple feeding conveyors corresponding to the batching slots, and the discharge port of the batching slot corresponds to the feeding port of the feeding conveyor. The middle part of the upper surface of the left and right end support plates of each feeding conveyor is provided with a fixed block, and a fixed rod is arranged between the fixed blocks, and the left and right ends of the fixed rod are provided with a separation guard plate to ensure that different raw materials do not mix during conveying.

[0099] When the control system issues an instruction, the corresponding batching tank is opened, and the raw materials are transported to the weighing member through the feeding conveyor. The weighing member includes a fixed frame arranged on the weighing sensor around the upper surface of the support frame. The lower surface of the fixed frame is connected with a lower hopper, and the lower hopper is arranged corresponding to the feed inlet of the mixing tank body. The discharge outlets of the plurality of feeding conveyors are provided with inclined guide hoppers corresponding to the weighing member, which accurately guide the conveyed raw materials into the lower hopper. The weighing sensor monitors the weight of the raw materials in the lower hopper in real time. When the weight set by the formula is reached, the control system stops the operation of the corresponding feeding conveyor, ensuring the accurate amount of each raw material. This automatic and sensor-controlled batching method avoids the errors that may occur in traditional manual batching, ensuring the accuracy of formula execution.

[0100] After all the solid raw materials are weighed, a U-shaped support rod is arranged on the lower hopper of the weighing member, and a plurality of telescopic cylinders are embedded in the middle of the crossbar. The end of the telescopic rod of the telescopic cylinder is provided with an openable and closable plate for opening and closing the lower hopper. The control system drives the telescopic cylinder to extend, and the openable and closable plate opens, so that the accurately weighed solid raw materials are poured into the mixing tank body arranged in the support box.

[0101] After the solid raw materials enter the mixing tank body, the stirring and dispersing member starts to work. The stirring and dispersing member includes a driving motor, a rotating shaft and a plurality of dispersing rods. The support box is provided with support blocks at the left and right ends of the upper surface, and one of the support blocks is provided with a driving motor. The output end of the driving motor is connected with a horizontally arranged rotating shaft, and the two ends of the rotating shaft are rotatably supported on the side wall of the mixing tank body through bearings. A plurality of groups of stirring rods are arranged on the rotating shaft at equal distances along the axial direction of the rotating shaft, and each group of stirring rods includes two rod bodies extending radially and arranged horizontally. The ends of each group of stirring rods are jointly connected with an arc-shaped stirring rod, and a plurality of connecting rods are arranged at equal distances on the inner side of the same arc-shaped stirring rod and connected between the upper and lower two stirring rods, and a plurality of dispersing rods are vertically arranged on each connecting rod. The driving motor drives the rotating shaft to rotate at high speed, and the plurality of groups of stirring rods, arc-shaped stirring rods and dispersing rods perform multi-dimensional and high-intensity stirring and dispersing of the materials in the mixing tank body. This complex stirring structure can effectively break up the possible clumps in the feed raw materials, ensure the materials to be fully mixed, and avoid the problems of mixing dead angle and insufficient dispersing in traditional stirring devices.

[0102] During the mixing process, in order to prevent the materials from adhering to the inner wall of the mixing tank body, a connecting plate is horizontally arranged at the upper end position between every two adjacent arc-shaped stirring rods. The middle part of the connecting plate is vertically embedded with a scraper telescopic cylinder, the telescopic rod of the scraper telescopic cylinder is extended downward, and the end of the telescopic rod is connected with an arc-shaped rubber scraper matched with the curvature of the inner wall of the mixing tank body. The scraper telescopic cylinder periodically drives the arc-shaped rubber scraper to scrape the inner wall of the mixing tank body, scrapes off the adhered materials and re-rolls them into the mixing area, avoids waste of materials and difficulty in cleaning, and ensures the accuracy of each mixing.

[0103] When the solid raw materials are mixed to a certain extent, liquid fermentation inoculum or moisture needs to be added. The rotating shaft is a hollow shaft, and a water outlet pipe is embedded in the inside of the hollow shaft. A plurality of atomizing spray heads are connected to the water outlet pipe at equal intervals along the length direction of the water outlet pipe, and the spray nozzles of the atomizing spray heads face the inside of the mixing tank. One end of the water outlet pipe is connected with a water inlet pipe penetrating through the rotating shaft through a rotary joint. The control system accurately controls the flow of the liquid additive through the liquid flow control valve connected to the water inlet pipe. The liquid additive is finally sprayed in the form of fine mist from the plurality of atomizing spray heads through the water inlet pipe and the water outlet pipe, and is uniformly distributed in the solid material in the mixing tank. This atomizing spray method avoids the problem of local over-wetting and clumping caused by traditional manual spraying or simple pipeline injection, ensures the uniform distribution of the liquid additive, and is beneficial to the subsequent fermentation process.

[0104] The entire fermentation feed solid-state fermentation premixing and dispersing equipment is uniformly managed by the control system. The control system is electrically connected with each weighing sensor, the driving device of each feeding conveyor belt, the driving motor, the plurality of telescopic cylinders, the scraper telescopic cylinder, and the liquid flow control valve connected to the water inlet pipe. Through the control system, the equipment can realize automatic control of formula automatic batching, weighing, feeding, mixing and dispersing, and liquid additive spraying. This highly integrated automation solution significantly improves the efficiency, accuracy and product quality consistency of the fermentation feed premixing process, and solves many deficiencies of traditional equipment in automation, mixing uniformity, liquid addition and cleaning and maintenance.

[0105] The above only describes the embodiments of the present application and does not limit the protection scope of the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
