TECHNICAL FIELD
[0001] The present application relates to the technical field of fertilizer processing, in particular to a granular compound organic fertilizer processing equipment and process. BACKGROUND
[0002] The granular compound organic fertilizer is a high-efficiency fertilizer made of organic matter, microorganisms, inorganic nutrients and other raw materials through scientific proportioning and granulation process. Its processing and handling process mainly includes raw material pretreatment and proportioning, fermentation, crushing and screening, mixing and conditioning, granulation, drying and cooling, screening and coating, and packaging and warehousing.
[0003] Mixing is the core link of fertilizer processing, which directly affects the uniformity of finished product nutrients, fermentation efficiency and product quality. The mixing link aims to fully homogenize various raw materials (livestock and poultry manure, straw, humic acid, microbial agents and fertilizer raw materials, etc.), ensure nutrient uniformity, fermentation synergy and process stability. The core problem in the mixing process is often the non-standard mixing uniformity.
[0004] The general mixing device mainly includes a mixing tank and a stirring paddle arranged in the tank, which is used for stirring and mixing different materials conveyed into the tank. Because the types of mixed materials are different, their particle sizes are different. In the raw material pretreatment process, the material size is difficult to unify after crushing. If the particle size is too large, it will directly affect the uniformity of mixing. If the particle size is too small, it will sink or float to the bottom or the upper layer of the material, and it is difficult to fully mix with other materials. SUMMARY
[0005] The purpose of the present application is to provide a granular compound organic fertilizer processing equipment and process to solve the problems raised in the background.
[0006] In order to solve the above technical problems, the present application provides the following technical scheme: a granular compound organic fertilizer processing equipment and process, comprising a mixing tank, a main shaft is rotatably arranged in the mixing tank, a support plate is fixed to the upper end of the main shaft, friction force sensing blocks are installed at both ends of the support plate, connecting shafts are fixed to the sides of the friction force sensing blocks, movable sleeves are arranged outside the friction force sensing blocks and the connecting shafts, connecting plates are fixed to the ends of the movable sleeves, stirring wheels are installed at the other ends of the connecting plates, the stirring wheels are hollow structures, a plurality of limiting holes are arranged at the bottoms of the stirring wheels, mounting plates are fixed inside the stirring wheels, and power modules are arranged on the mounting plates.
[0007] According to the above technical scheme, the diameters of the limiting holes are smaller than the maximum diameters allowed for material mixing. The mounting plate divides the space inside the stirring wheel into a counterweight area on the upper side and a sorting area on the lower side. The counterweight area is a closed space, and the power module as a whole serves as the initial counterweight of the counterweight area. The sorting area is in communication with the outside of the stirring wheel through the limiting holes.
[0008] According to the above technical solution, the inner surface of the movable sleeve is covered with an adsorption layer, and the connecting shaft is set as an electromagnetic block. When the connecting shaft is energized, the movable sleeve is fixedly connected to the connecting shaft, and the stirring wheel remains stationary in its current position. When the connecting shaft is de-energized, the movable sleeve, the friction sensing block, and the connecting shaft rotate in coordination. During the mixing process, the stirring wheel is affected by its own rotation speed and the material flow resistance, causing the movable sleeve to rotate. The friction sensing block is used to determine the rotation amplitude based on the detected friction force, thereby evaluating the mixing state of the material.
[0009] According to the above technical solution, the power module includes a steering box 1, which is vertically connected and has a pump body connected to its upper end. The input end of the pump body corresponds to the steering box 1. The mounting plate has a through hole in cooperation with the steering box 1. The output end of the pump body is connected to a steering box 2. The steering box 2 has an outlet 1 facing the main shaft. The outlet 1 is connected to at least one output pipe. The other end of the output pipe is inclined downward. The stirring wheel has a window in cooperation with the output pipe.
[0010] According to the above technical solution, the steering box 2 has an outlet 2 on the other side of the outlet 1. The outlet 2 is connected to the counterweight area. A rotating shaft is installed inside the steering box 2. One end of the rotating shaft that extends out of the steering box 2 is connected to a driver 1. A valve block 1 is fixed on the rotating shaft. The cross-section of the valve block 1 is a non-circular structure.
[0011] According to the above technical solution, the surface of valve block one includes a plane and an arc surface. When valve block one is rotated to the plane facing upward, outlet one and outlet two are both in a closed state. When valve block one is rotated to the plane facing outlet one and pump body, outlet one is connected to the interior of steering box two, and outlet two is closed. When valve block one is rotated to the plane facing outlet two and pump body, outlet two is connected to the interior of steering box two, and outlet one is closed.
[0012] According to the above technical solution, a valve block 2 is installed at the bottom of the steering box 1, and a cylinder 1 is connected to one side of the valve block 2. The cylinder 1 is installed on the mounting plate, and a mass sensing module is installed on the mounting plate.
[0013] According to the above technical solution, the valve block two has a Z-shaped channel inside, which includes a low-position channel and a high-position channel. The valve block two has lateral openings on both sides relative to the low-position channel.
[0014] According to the above technical solution, the main shaft is connected to a pulley set, and the pulley set is connected to a second driver.
[0015] According to the above technical solution, a second cylinder is fixed on the surface of the mixing tank, and a drive shaft is hinged to the drive end of the second cylinder. The drive shaft is rotatably mounted on the surface of the mixing tank, and a valve is connected to the bottom of the drive shaft. The mixing tank is equipped with a discharge port in cooperation with the valve.
[0016] According to the above technical solution, a feeding mechanism is provided around the mixing tank. The feeding mechanism includes a support frame, on which several rollers are rotatably mounted. A conveyor belt covers the rollers. A hopper is mounted on one side of the conveyor belt, and the other side of the conveyor belt corresponds to the top of the mixing tank. One of the rollers is connected to a driver.
[0017] Compared with existing technologies, the beneficial effects achieved by this invention are as follows: This invention, through the sorting zone and limiting holes set inside the stirring wheel, continuously and dynamically sorts materials during the mixing process. Materials of suitable volume pass freely, while excessively large materials are isolated outside the stirring wheel and subjected to targeted secondary crushing by the pressure of the stirring wheel and the tank wall. This effectively avoids over-crushing of suitable materials, ensuring the uniformity of particle size in the final product, and fundamentally improving mixing uniformity and product quality.
[0018] Equipped with a power module, a highly efficient internal material conveying system is formed. It actively pumps qualified small particles separated from the mixing wheel to the inner perimeter of the mixing tank, while materials from the perimeter (including larger particles to be crushed) automatically replenish the inner perimeter, forming a circulation. This accelerates the spatial separation of particles of different sizes, ensuring that larger particles are more efficiently conveyed to the crushing area (between the mixing wheel and the tank wall) for processing, greatly improving overall mixing and sorting efficiency. The power module provides four operating modes, enabling a single device to perform multiple functions: Mode 1 (Pure Counterweight): Provides basic mixing function. Mode 2 (Sorting and Conveying): Realizes the core sorting and material conveying functions. Mode 3 (Dynamic Counterweight): Small particles can be temporarily injected into the counterweight area, dynamically increasing the inertia and compressive force of the mixing wheel to meet the crushing requirements of materials with different hardness or lumps. Mode 4 (Cleanup and Reset): Emptys the temporarily stored material in the counterweight area, restoring the initial counterweight to prepare for the next batch of production or different process requirements.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0033] Please see Figures 1-11The present invention provides a technical solution: a granular compound organic fertilizer processing equipment, including a mixing tank 1, a main shaft 2 rotatably arranged inside the mixing tank 1, a support plate 3 fixed at the upper end of the main shaft 2, friction sensing blocks 31 installed at both ends of the support plate 3, a connecting shaft 32 fixed on the side of the friction sensing blocks 31, a movable sleeve 33 sleeved outside the friction sensing blocks 31 and the connecting shaft 32, a connecting plate 34 fixed at the end of the movable sleeve 33, a stirring wheel 4 installed at the other end of the connecting plate 34, the stirring wheel 4 is set as a hollow structure, several limiting holes 41 are provided at the bottom of the stirring wheel 4, an installation plate 42 is fixed inside the stirring wheel 4, and a power module is provided on the installation plate 42.
[0034] It should be added that: such as Figure 2 , Figure 3 As shown, the diameter of the limiting hole 41 is smaller than the maximum diameter allowed for material mixing. The mounting plate 42 divides the space inside the stirring wheel 4 into an upper counterweight zone 43 and a lower sorting zone 44. The counterweight zone 43 is a closed space, with the entire power module serving as the initial counterweight. The sorting zone 44 is connected to the outside of the stirring wheel 4 through the limiting hole 41. The stirring wheel 4 is close to the bottom of the mixing tank 1 and forms a certain angle with the side wall of the mixing tank 1. When the stirring wheel 4 is stirring, particles of suitable size can pass smoothly through the limiting hole 41 into the sorting zone 44 while being mixed, and return to the mixing tank 1 through the limiting hole 41 on the other side of the stirring wheel 4. Materials that are too large are intercepted on the outside of the stirring wheel 4, and during the stirring process, they are squeezed by the surface of the stirring wheel 4 and the inner wall of the mixing tank 1, producing an additional crushing effect, thereby obtaining materials of ideal size. While performing secondary processing on materials that are too large, secondary crushing of materials of suitable size is avoided, resulting in materials that are too small, thus ensuring the uniformity of material mixing.
[0035] In one embodiment, such as Figure 4 As shown, the inner surface of the movable sleeve 33 is covered with an absorbent layer, and the connecting shaft 32 is configured as an electromagnetic block. When the connecting shaft 32 is energized, the movable sleeve 33 is fixedly connected to the connecting shaft 32, and the stirring wheel 4 remains stationary. When the connecting shaft 32 is de-energized, the movable sleeve 33, the friction sensing block 31, and the connecting shaft 32 rotate in coordination. During the mixing process, the stirring wheel 4 is affected by its own rotation speed and the resistance to material flow, causing the movable sleeve 33 to rotate. The friction sensing block 31 is used to determine the rotation amplitude based on the detected friction force, thereby evaluating the mixing state of the material. In actual operation, the relative position of the stirring wheel 4 and the main shaft 2 can be adjusted by increasing or decreasing the instantaneous rotation speed, using inertia, thereby adjusting the angle between the stirring wheel 4 and the inner wall of the mixing tank 1.
[0036] like Figure 5As shown, the power module includes a steering box 5, which is vertically connected and has a pump body 6 connected to its upper end. The input end of the pump body 6 corresponds to the steering box 5. The mounting plate 42 has a through hole 421 that cooperates with the steering box 5. The output end of the pump body 6 is connected to a steering box 7. The steering box 7 has an outlet 71 on the side facing the main shaft 2. The outlet 71 is connected to at least one output pipe 72. The other end of the output pipe 72 is inclined downward. The stirring wheel 4 has a window 45 that cooperates with the output pipe 72.
[0037] In actual operation, the inclined output pipe 72 can prevent material from entering in reverse. When the pump body 6 starts, it can extract the material in the sorting zone 44. The material is transferred to the output pipe 72 through the outlet 71 of the diverting box 2 7, and then transported to the inner area of the mixing tank 1 through the window 45. The material that was originally in the inner area of the mixing tank 1 will automatically flow to the outer area to replenish it, thereby achieving the effect of mixing materials of appropriate size while transferring them to the inner area of the mixing tank 1. Large-volume materials will gradually transfer to the outer area of the mixing tank 1 and be crushed again by the stirring wheel 4, further improving the quality of material mixing.
[0038] Furthermore, such as Figure 6 , Figure 7 As shown, the steering box 2 7 has an outlet 2 73 on the other side of the outlet 1 71. The outlet 2 73 is connected to the counterweight area 43. The steering box 2 7 is equipped with a rotating shaft 74. One end of the rotating shaft 74 that extends out of the steering box 2 7 is connected to a driver 1 75. A valve block 1 76 is fixed on the rotating shaft 74. The cross-section of the valve block 1 76 is a non-circular structure.
[0039] In actual operation, the actuator 75 is used to control the rotation of valve block 76 within steering box 7 via shaft 74. The surface of valve block 76 includes a flat surface 761 and an arc surface 762. When valve block 76 rotates to the position where flat surface 761 faces upwards, outlet 71 and outlet 73 are both closed. When valve block 76 rotates to the position where flat surface 761 faces outlet 71 and pump body 6, outlet 71 is connected to the interior of steering box 7, and outlet 73 is closed. When valve block 76 rotates to the position where flat surface 761 faces outlet 73 and pump body 6, outlet 73 is connected to the interior of steering box 7, and outlet 71 is closed.
[0040] Furthermore, such as Figure 6 As shown, a valve block 51 is installed at the bottom of the steering box 5. A cylinder 52 is connected to one side of the valve block 51. The cylinder 52 is mounted on the mounting plate 42, and a mass sensing module is installed on the mounting plate 42.
[0041] Preferred, such as Figure 8 , Figure 9As shown, the valve block 2 51 has a Z-shaped channel 511 inside. The Z-shaped channel 511 includes a low channel 512 and a high channel 513. The valve block 2 51 has lateral openings 514 on both sides relative to the low channel 512.
[0042] In actual operation, when the Z-shaped channel 511 is completely inside the steering box 5, the low channel 512 corresponds to the through hole 421, and the high channel 513 corresponds to the inside of the steering box 5. When the cylinder 52 starts and pushes the valve block 51, the low channel 512 is pushed out of the area of the steering box 5. At this time, the lower end of the low channel 512 is closed, the side opening 514 communicates with the outside, and the high channel 513 still corresponds to the inside of the steering box 5.
[0043] The following are supplementary explanations based on the above structure: The power module includes the following modes: Mode 1: Pump body 6 is in the off state, and the power module only acts as a counterweight component. Mode 2: Output pipe 72 is connected to steering box 2 7, and steering box 1 5 is connected to sorting area 44. In this mode, the power module is used to transfer materials of suitable size to the inner area of mixing tank 1. Mode 3: Steering box 2 7 is connected to counterweight area 43, and steering box 1 5 is connected to sorting area 44. In this mode, the power module is used to transfer materials in sorting area 44 to counterweight area 43, increasing the overall counterweight of counterweight area 43. This can be used to improve the inertia of stirring wheel 4 or the extrusion pressure between it and mixing tank 1. The mass sensing module is used to detect the transfer amount. Mode 4: Output pipe 72 is connected to steering box 2 7, and steering box 1 5 is connected to counterweight area 43. In this mode, the power module is used to transfer accumulated materials in counterweight area 43 to the inner area of mixing tank 1.
[0044] Optional, such as Figure 10 As shown, the main shaft 2 is connected to a pulley set 21, and the pulley set 21 is connected to a driver 22.
[0045] A cylinder 11 is fixed on the surface of the mixing tank 1. A drive shaft 12 is hinged to the drive end of the cylinder 11. The drive shaft 12 is rotatably mounted on the surface of the mixing tank 1. A valve 13 is connected to the bottom of the drive shaft 12. The mixing tank 1 is equipped with a discharge port in cooperation with the valve 13.
[0046] In actual operation, the second driver 22 is used to drive the main shaft 2 to rotate via the pulley group 21. The second cylinder 11 controls the rotation of the drive shaft 12 through its telescopic movement, thereby controlling the valve 13 to disengage or close the discharge port.
[0047] like Figure 11 As shown, a feeding mechanism 8 is provided around the mixing tank 1. The feeding mechanism 8 includes a support 81, on which several rollers 82 are rotatably mounted. A conveyor belt 83 covers the rollers 82. A hopper 84 is mounted on one side of the conveyor belt 83, and the other side of the conveyor belt 83 corresponds to the top of the mixing tank 1. One of the rollers 82 is connected to a driver 85.
[0048] In actual operation, the material is fed from the hopper 84 onto the conveyor belt 83. The driver 85 controls the rotation of the roller 82 to drive the conveyor belt 83 to move, thereby realizing the feeding of the material.
[0049] The specific processing technology is as follows:
[0050] Step 1: Automatic feeding and premixing. Start driver 3 85 to continuously or batch feed raw materials into mixing tank 1 through hopper 84. Start driver 2 22 to perform preliminary mixing.
[0051] Step 2: Sorting and core mixing. Switch the power module to the output pipe 72, which is connected to the steering box 2 7, and the steering box 1, which is connected to the sorting zone 44. Start the pump body 6 to continuously pump the qualified small particles in the sorting zone 44 of the stirring wheel 4 back to the inner wall of the mixing tank 1. Monitor the data of the friction sensor block in real time. If the feedback resistance continues to increase, it indicates that the material is viscous or there are many large particles. The "instant acceleration-fallback" operation can be performed to increase the angle between the stirring wheel 4 and the tank wall by using inertia, thereby enhancing the shearing and crushing force on large particles. If abnormal resistance is detected due to excessively large or hard clumps, the material in the sorting zone can be pumped into the counterweight zone 43 for a short time to increase the counterweight of the stirring wheel 4, thereby increasing its inertia and crushing ability on clumps. After the resistance returns to normal, switch back to the initial state.
[0052] Step 3: Fine mixing and homogenization. In the middle and later stages of mixing, the connecting shaft 32 is briefly de-energized at regular intervals, allowing the movable sleeve 33 to rotate freely within a certain angle. This allows the stirring wheel 4 to continuously fine-tune its angle under the action of material resistance, forming a changing flow field, breaking the mixing dead zone, and achieving more thorough fine mixing. The mass sensing module monitors the amount of material transferred in the counterweight zone 43 in real time, and the friction force sensing block continuously evaluates the rheological characteristics of the overall mixture.
[0053] Step 4: Discharge. When the mixing uniformity reaches the preset standard, stop the driver 22 and pump 6, empty the material temporarily stored in the counterweight zone 43 into the inner circumference of the mixing tank 1, and ensure that the counterweight zone 43 restores its initial counterweight to prepare for the next batch. Start cylinder 2 11 and open valve 13. The fertilizer that is mixed evenly and has qualified particle size is discharged under the action of gravity.

A granular compound organic fertilizer processing technology, applicable to the granular compound organic fertilizer processing equipment described in claim 9, characterized in that, The specific process is as follows: Step 1: Automatic feeding and premixing. Start driver 3 (85) to continuously or batch feed raw materials into mixing tank (1) through hopper (84), and start driver 2 (22) for preliminary mixing; Step 2: Sorting and core mixing. Switch the power module to the output pipe (72) and connect it to the steering box 2 (7). (5) The steering box 1 is connected to the sorting area (44). Start the pump body (6) and continuously pump the qualified small particles in the sorting area (44) of the stirring wheel (4) back to the inner perimeter of the mixing tank (1). Monitor the data of the friction sensing block in real time. If the feedback resistance continues to increase, it indicates that the material is viscous or there are many large particles. The "instant acceleration-fallback" operation can be performed to increase the angle between the stirring wheel (4) and the tank wall by using inertia, thereby enhancing the shearing and crushing force on large particles. If an abnormal resistance is detected due to an excessively large or hard agglomerate, the material in the sorting area can be pumped into the counterweight area (43) for a short time to increase the counterweight of the stirring wheel (4) and enhance its inertia and crushing ability on the agglomerate. After the resistance returns to normal, switch back to the initial state. Step 3: Fine mixing and homogenization. In the middle and late stages of mixing, the connecting shaft (32) is briefly de-energized at regular intervals, allowing the movable sleeve (33) to rotate freely within a certain angle. This allows the stirring wheel (4) to continuously fine-tune its angle under the action of material resistance, forming a changing flow field, breaking the mixing dead zone, and achieving more thorough fine mixing. The mass sensing module monitors the amount of material transferred in the counterweight zone (43) in real time, and the friction sensing block continuously evaluates the rheological characteristics of the overall mixture. Step 4: Discharge. When the mixing uniformity reaches the preset standard, stop the second driver (22) and the pump (6), empty the material temporarily stored in the counterweight area (43) into the inner circumference of the mixing tank (1), ensure that the counterweight area (43) is restored to its initial counterweight, and prepare for the next batch. Start the second cylinder (11), open the valve (13), and the fertilizer that is mixed evenly and has qualified particle size is discharged under the action of gravity.
