[0038] The enzyme preparation catalytic weathered coal preparation humic acid system provided by the present disclosure can promote the biological catalytic reaction of enzyme preparation and weathered coal through the classification screening of the screening device, the efficient mixing of the stirring device, and the consistency and accuracy of product packaging ensured by the packaging device. The enzyme preparation catalytic weathered coal preparation humic acid system provided by the present disclosure uses environmentally friendly enzyme catalysis technology, reduces the use of chemical reagents, reduces environmental pollution, and realizes stable output of high-quality products.

[0039] For ease of understanding, the specific structure and working principle of the enzyme preparation catalytic weathered coal preparation humic acid system of the present disclosure will be described in detail below with reference to Figures 1 to 7

[0040] As Figures 1 to 7 ​As shown, the present disclosure relates to an enzyme preparation catalytic weathered coal preparation humic acid system, comprising: a storage device 1, the storage device 1 is configured to store weathered coal; a screening device 2, the screening device 2 is connected with the storage device 1 through a first conveying belt 5, one end of the first conveying belt 5 is connected with a first discharge port 6 of the storage device 1, and the other end is connected with a first feeding port 7 of the screening device 2, weathered coal is output from the first discharge port 6 of the storage device 1, and is conveyed from one end to the other end of the first conveying belt 5 and enters the screening device 2; a stirring device 3, the stirring device 3 is connected with the screening device 2 through a second conveying belt 8, and the stirring device 3 is configured to mix weathered coal and enzyme preparation; a packaging device 4, the packaging device 4 is configured to package the mixture of weathered coal and enzyme preparation.

[0041] Specifically, the present disclosure relates to an enzyme preparation catalytic weathered coal preparation humic acid system, wherein weathered coal is a metamorphic form of coal that has been subjected to physical, chemical and biological effects of air, water and microorganisms in the natural environment for a long time, characterized by a decrease in carbon content, an increase in volatile matter, a decrease in hardness and a decrease in calorific value. In this process, the organic matter in the coal undergoes oxidation reaction with oxygen, increasing the number of oxygen-containing functional groups, while the moisture dissolves part of the minerals and accelerates the degradation of organic matter; and the microorganisms in the soil decompose the complex organic compounds in the coal to generate simpler and more beneficial substances to the soil, such as humic acid and fulvic acid. Therefore, weathered coal is rich in humic acid and becomes an important agricultural soil conditioner for improving soil structure, increasing water retention capacity and promoting plant growth.

[0042] Referring to Figures 1 to 3 The enzyme preparation catalytic weathered coal preparation humic acid system of the present disclosure comprises a storage device 1, which is configured to store weathered coal raw materials to be processed. The storage device is of large capacity structure, thereby ensuring continuous supply of weathered coal. The internal structure design of the storage device 1 is crucial to ensure smooth flow of materials, especially when dealing with materials like weathered coal that are prone to caking or forming arching phenomenon (i.e. materials accumulate in an arch shape without flowing). Therefore, the bottom of the storage device 1 is designed in a conical or wedge shape, thereby helping the materials to naturally slide to the outlet, reducing the opportunity for the materials to stagnate on the corners or side walls, and promoting uniform flow.

[0043] As Figure 1As shown, the screening device 2 is closely connected with the storage device 1 through the first conveying belt 5, specifically, one end of the first conveying belt 5 is connected with the first discharge port 6 of the storage device 1, and the other end is connected with the first feeding port 7 of the screening device 2, and the first conveying belt 5 ensures that the weathered coal can be smoothly and continuously output from the storage device 1 and efficiently conveyed into the screening device 2 for screening. The weathered coal is output from the first discharge port 6 of the storage device 1 to one end of the first conveying belt 5, and gradually moves to the other end of the first conveying belt 5 with the movement of the first conveying belt 5. In order to ensure the stability and integrity of the weathered coal during transportation, the width and speed of the first conveying belt 5 can be set according to actual needs, which are not limited here. The weathered coal enters the first feeding port 7 of the screening device 2 through the first conveying belt 5, and in order to further improve the smoothness of the material flow, a guide plate can be installed around the feeding port to help the weathered coal evenly distribute and smoothly enter the inside of the screening device 2. The screening device 2 is internally provided with multiple screen layers of different specifications for classifying the weathered coal according to particle size. Through vibration or rotation, the screening device 2 can effectively separate out fine particles meeting the requirements, while discharging larger or non-standard materials, ensuring that only the qualified materials after screening continue to enter the next process.

[0044] As shown in Figure 3 After screening by the screening device 2, the weathered coal meeting the requirements directly enters the stirring device 3. The stirring device 3 is connected with the screening device 2 through the second conveying belt 8, and through the stirring of the stirring device 3, the weathered coal is uniformly mixed with the enzyme preparation. The stirring device 3 is internally provided with a stirring mechanism, which not only can generate strong shear force to ensure that each piece of weathered coal can fully contact with the enzyme preparation, but also promotes the circulation flow of the material in the container to prevent local accumulation. During the whole stirring process, the dynamic mixing of the weathered coal and the enzyme preparation not only disperses the two components rapidly, but also with the rotation of the stirring mechanism, the enzyme preparation gradually penetrates into the small gaps between the weathered coal particles, starts the biological catalytic reaction, and lays a solid foundation for the efficient preparation of humic acid. The enzyme preparation in the present disclosure contains 30% of aerobic bacteria, 40% of facultative bacteria, and 30% of anaerobic bacteria. After the weathered coal is catalyzed by the enzyme preparation, it becomes high-activity humic acid with many functional groups, not only the proportion of free acid in the humic acid is higher, and the water-soluble phytate or hydrophilic complex is more, but also the growth environment of soil microorganisms is rapidly improved, the total amount of microorganisms is greatly improved, and the continuous cropping obstacles and soil-borne diseases can be effectively controlled.

[0045] As shown in Figure 3As shown, the packaging device 4 is the terminal equipment in the enzyme preparation catalytic weathered coal humic acid system, which is configured to package the treated weathered coal and enzyme preparation mixture. The packaging device 4 not only ensures the proper packaging of the product, but also improves the automation level and overall efficiency of the production process. At the same time, the packaging device 4 uses high-performance packaging materials, such as moisture-proof and oxidation-resistant composite films or bags, to protect the stability and activity of the humic acid product during storage and transportation. In addition, the device integrates automatic sealing and label printing functions inside, ensuring that each package is well sealed and attached with detailed product information and batch identification for traceability management. During the entire packaging process, the system realizes highly automated operation through PLC (Programmable Logic Controller), reducing manual intervention, reducing pollution risk, and improving work efficiency.

[0046] As Figures 2 to 3 shown, in one embodiment of the present disclosure, the enzyme preparation catalytic weathered coal humic acid system further comprises a dosing device 9, which is configured to add enzyme preparation to the stirring device 3.

[0047] Specifically, the dosing device 9 is used to add enzyme preparation to the stirring device 3, and the dosing device 9 is also provided with a metering mechanism, which can ensure that the enzyme preparation is added to the weathered coal at a predetermined flow rate and proportion, thereby maintaining the consistency of the reaction conditions and the stability of the product quality. In order to adapt to different production process requirements, the dosing device 9 supports multiple dosing methods, such as direct spraying, etc., to ensure uniform dispersion of the enzyme preparation in the entire material.

[0048] In one embodiment of the present disclosure, a first crushing unit is provided in the storage device 1, which is configured to crush the weathered coal in the storage device 1.

[0049] The storage device 1 is equipped with a first crushing unit, which is designed to crush the weathered coal within the storage device 1 to ensure the efficiency of subsequent processing steps. Specifically, the storage device 1 has a wide-diameter feed hopper at its bottom, directly connected to the inlet of the first crushing unit, allowing large pieces of weathered coal to smoothly enter the crushing area. Below the feed hopper is a pre-crushing zone equipped with robust toothed plates or coarse crushing hammers to initially crush the large pieces of weathered coal, preparing them for subsequent fine crushing. The core component of the storage device 1 is the main crushing chamber, located below the feed hopper, which contains various types of crushing components, such as hammer mills or roller crushers. These components are flexibly selected according to the hardness of the weathered coal and the required particle size, applying impact or extrusion force to the material through high-speed rotating hammers or relatively rotating rollers, crushing it into fine particles that meet the requirements. To further optimize the crushing effect, a vibration device is also installed inside the storage device 1. Periodic vibration helps the material to be evenly distributed within the crushing chamber and accelerates the sieving process of fine particles, preventing blockage. The first crushing unit, by breaking larger pieces of weathered coal into finer, more uniform particles, not only improves the efficiency of subsequent processes such as screening and mixing but also promotes full contact and reaction between the enzyme preparation and the weathered coal.

[0050] like Figures 4 to 5 As shown, in one embodiment of this disclosure, a sieve plate is provided inside the screening device 2, which divides the screening device 2 into a first inner cavity 21 and a second inner cavity 22. The first inner cavity 21 is located below the second inner cavity 22. The particle size of the weathered coal particles in the second inner cavity 22 is larger than that of the weathered coal particles in the first inner cavity 21. The first feed inlet 7 of the screening device 2 is connected to the second inner cavity 22.

[0051] Specifically, the screening device 2 is equipped with a screen plate that divides the entire device into two inner cavities: a lower first inner cavity 21 and an upper second inner cavity 22. This arrangement ensures that weathered coal particles are effectively separated according to their size, with the particles in the second inner cavity 22 being larger than those in the first inner cavity 21. The first feed inlet 7 of the screening device 2 is directly connected to the second inner cavity 22. When weathered coal enters the screening device 2 from the storage device 1 via the conveyor belt, the material first falls into the second inner cavity 22, where larger particles are temporarily retained, while smaller particles pass through the screen plate and fall smoothly into the first inner cavity 21. The screen plate is designed to accommodate different particle sizes and typically uses a metal mesh or perforated plate with specific apertures. The aperture size can be selected according to actual needs and is not limited here.

[0052] In order to further optimize the screening performance, the screen plate is also equipped with a vibrating device, which helps the material to be evenly distributed and accelerates the screening process of small particles through periodic vibration. During the entire screening process, the qualified small particle weathered coal collected in the first inner cavity 21 will be directly transported to the next process, and the large particle material retained in the second inner cavity 22 can be discharged for regrinding or other processing. This upper and lower layered screening arrangement not only improves the accuracy of material screening, but also significantly improves the processing capacity and production efficiency of the entire system, providing high-quality raw material guarantee for subsequent mixing and other steps.

[0053] As shown in Figures 3 to 5 In one embodiment of the present disclosure, the second discharge port 10 of the screening device 2 is in communication with the first inner cavity 21, the third discharge port 11 of the screening device 2 is in communication with the second inner cavity 22, and the second discharge port 10 is connected to the second conveying belt 8.

[0054] The screening device 2 is equipped with multiple discharge ports: the second discharge port 10 is in communication with the first inner cavity 21 for discharging small particle weathered coal after screening; and the third discharge port 11 is in communication with the second inner cavity 22 for discharging larger particle material.

[0055] Specifically, when the weathered coal enters the screening device 2 from the storage device 1 through the conveying belt, the material first enters the second inner cavity 22, where the larger particle weathered coal is temporarily intercepted, and the smaller particles fall smoothly into the first inner cavity 21 through the screen plate. The qualified small particle weathered coal in the first inner cavity 21 is discharged through the second discharge port 10 and directly connected to the second conveying belt 8, ensuring that these materials can be smoothly transported to the next process. At the same time, the large particle material retained in the second inner cavity 22 is discharged through the third discharge port 11 for further processing.

[0056] The multiple discharge port arrangement of the screening device 2 not only simplifies the operation process of material diversion, but also improves the flexibility and adaptability of the system, which can flexibly adjust the material flow direction according to different production needs, ensuring that weathered coal of different particle sizes is effectively separated and processed, and providing a solid guarantee for the continuous operation of the entire humic acid preparation system and product quality.

[0057] As shown in Figures 3 to 5 In one embodiment of the present disclosure, the enzyme preparation catalyzed weathered coal preparation humic acid system further comprises a second grinding unit 12, the second grinding unit 12 is in communication with the third discharge port 11, the second grinding unit 12 is configured to grind the weathered coal output by the third discharge port 11, and the fourth discharge port 13 of the second grinding unit 12 is connected to the first conveying belt 5.

[0058] Specifically, in the enzyme preparation catalytic weathered coal humic acid preparation system of the present disclosure, a second crushing unit 12 is also included, which is directly connected to the third discharge port 11 of the screening device 2. The second crushing unit 12 is used to process large particles of weathered coal discharged from the third discharge port 11, ensuring that these large particles of weathered coal can be further crushed to meet the particle size requirements of subsequent processes. After preliminary screening, the large particles of weathered coal remaining in the second inner cavity 22 enter the second crushing unit 12 through the third discharge port 11 and are efficiently broken into smaller and more uniform particles. The second crushing unit 12 is provided with crushing equipment such as a hammer crusher or a roller crusher, and can flexibly adjust the crushing intensity according to specific needs, ensuring that the output material has consistent particle size and is suitable for subsequent processing.

[0059] The second crushing unit 12 not only improves the overall uniformity of the material, but also significantly optimizes the efficiency and product quality of the entire system. In addition, considering dust control and environmental protection, a dust collection system or a closed structure will be installed inside the second crushing unit 12 to prevent dust generated during the crushing process from escaping and reduce the impact on the environment.

[0060] After crushing, the weathered coal is discharged through the fourth discharge port 13 of the second crushing unit 12 and directly connected to the first conveying belt 5, so that the crushed weathered coal can quickly and stably return to the front end of the system and re-enter the screening device 2 for further screening. The second crushing unit 12 ensures that any material that does not meet the particle size standard can be effectively processed twice, thereby improving the quality stability and production efficiency of the final product.

[0061] As shown in FIG. 1, Figures 2 to 3 In one embodiment of the present disclosure, a pulping device 14 is provided between the screening device 2 and the stirring device 3, which is configured to process weathered coal into coal slurry.

[0062] Specifically, a pulping device 14 is also provided between the screening device 2 and the stirring device 3, which is configured to process the screened weathered coal into uniform and fine coal slurry. Not only does it further optimize the physical properties of the material, but it also significantly improves the efficiency and quality of the subsequent enzyme preparation catalytic reaction. The pulping device 14 introduces an appropriate amount of water or other liquid medium, combined with efficient stirring and grinding mechanisms, to ensure that weathered coal particles are fully dispersed and form a stable suspension, making it easier for organic components in weathered coal to contact with enzyme preparations and promoting efficient conversion of humic acid.

[0063] Small particles of weathered coal discharged from the first inner cavity 21 of the screening device 2 enter the slurry preparation device 14 via a conveyor belt. Inside the slurry preparation device 14, they are mixed with a pre-proportioned liquid and, after vigorous stirring and grinding, transformed into a highly fluid coal slurry. The slurry, after preparation, is directly transported through a transmission pipeline to the stirring device 3 for uniform mixing with the enzyme preparation. By processing weathered coal into a coal slurry, the slurry preparation device 14 significantly improves the uniformity and reactivity of the material, enhancing the overall system's processing capacity and product quality.

[0064] In one embodiment of this disclosure, the stirring device 3 is provided with a stirring assembly inside, which is configured to mix weathered coal and enzyme preparation; a temperature sensor is provided at the edge of the stirring device 3, which is configured to detect the temperature inside the stirring device 3.

[0065] Specifically, the mixing device 3 is equipped with a mixing assembly for efficiently mixing weathered coal and enzyme preparations, ensuring that the two can fully contact and react. The mixing assembly typically includes various types of impellers or propellers. These designs not only generate strong shear forces, ensuring that each piece of weathered coal is uniformly mixed with the enzyme preparation, but also promote the circulation of materials within the container, preventing localized accumulation. To optimize the mixing effect, the mixing device 3 is also equipped with an adjustable-speed motor and an intelligent control system, which can dynamically adjust the mixing speed and time according to actual needs to ensure the optimal mixing ratio.

[0066] Furthermore, to control and monitor reaction conditions, a temperature sensor is installed at the edge of the stirring device 3. This sensor is configured to detect temperature changes within the stirring device 3 in real time, thereby maintaining optimal enzyme activity. Connected to a temperature control system, the temperature sensor provides immediate feedback, helping to automatically adjust the heating or cooling devices to maintain an ideal temperature environment conducive to the enzyme's catalytic reaction. This not only ensures the stability and consistency of the reaction process but also effectively avoids product quality variations caused by temperature fluctuations.

[0067] like Figure 6 As shown, in one embodiment of this disclosure, the packaging device 4 is provided with a weight sensor 15, which is configured to detect the weight of the mixture each time it is packaged.

[0068] Specifically, after the processed weathered coal and enzyme mixture enter the packaging device 4, the weight sensor 15 continuously measures the material during the filling process. Based on the real-time measurement data, the packaging device 4 can automatically adjust the filling amount to ensure that the weight of the mixture in each bag is consistent. This not only avoids quality problems caused by weight differences but also reduces material waste and improves production efficiency. In addition, the data from the weight sensor 15 can also be used to generate detailed production reports, facilitating quality traceability and management.

[0069] As Figure 7 shown, in one embodiment of the present disclosure, the packaging device 4 is provided with a control system 16 configured to control the opening and closing of the packaging device 4, as well as the action parameters of the packaging action.

[0070] Specifically, the control system 16 achieves comprehensive monitoring and automated management of the packaging process by integrating various sensors and actuators. When the treated weathered coal and enzyme preparation mixture is ready for packaging, the control system 16 will start the packaging device 4 according to the pre-set program and monitor the data of the weight sensor 15 in real time during the material filling process to ensure that the weight of the material in each packaging bag is consistent and meets the requirements. Once the specified weight is reached, the control system 16 will immediately stop filling and trigger the sealing mechanism to ensure good sealing.

[0071] In addition, the control system 16 can also flexibly adjust the action parameters of the packaging action according to different packaging specifications. For example, when handling different sizes or types of packaging bags, it can automatically change the sealing temperature, time, and cutting position to ensure the quality and appearance consistency of each packaging bag. For products that need to be labeled, the control system 16 can also coordinate the work of the label printer to ensure that the label content is accurately attached to each package with detailed product information and batch identification for traceability management.

[0072] In order to further improve the safety and reliability of the operation, the control system 16 is equipped with fault detection and alarm functions. Once an abnormal situation such as overweight, underweight or equipment failure is found, the system will immediately issue an alarm and suspend operation to correct the problem in time and prevent defective products from entering the market. At the same time, the control system 16 supports remote monitoring and data recording, and management personnel can check the status of the packaging process at any time through the central control system 16 for data analysis and production scheduling to ensure the continuity and stability of production.

[0073] The enzyme preparation catalytic weathered coal preparation humic acid system provided by the present disclosure can ensure the consistency and accuracy of product packaging through the classification screening of the screening device, efficient mixing of the stirring device, and promotion of the biological catalytic reaction of the enzyme preparation and weathered coal. The enzyme preparation catalytic weathered coal preparation humic acid system provided by the present disclosure uses environmentally friendly enzyme catalysis technology, reduces the use of chemical reagents, reduces environmental pollution, and realizes stable output of high-quality products.
