Description

Technical Field

[0001] This invention relates to the field of organic fertilizer technology, specifically to a method for preparing organic fertilizer for high humic acid flue gas. Background Technology

[0002] Currently, the organic fertilizers used for tobacco on the market are mainly ordinary organic fertilizers. Tobacco leaves have a relatively high demand for humic acid during their growth process. Humic acid can improve the oiliness and nicotine content of tobacco leaves, and also improve the aroma of tobacco leaves to a certain extent. However, existing organic fertilizers do not have this function.

[0003] When organic fertilizers are used, tobacco plants may experience slow growth due to insufficient decomposition, failing to meet the growth requirements of tobacco leaves.

[0004] After organic fertilizer has decomposed, it needs to be dried and then screened. The drying process is inefficient. After drying, the organic fertilizer needs to be screened to remove the humus that has not been fermented and decomposed. Existing screening equipment is very troublesome to discharge and it is not easy to pour out and remove the screened impurities.

[0005] Based on the above description, this application proposes a method for preparing organic fertilizer for high humic acid flue gas. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a method for preparing high-humic acid organic fertilizer for tobacco, which solves the problem that existing organic fertilizers cannot adequately meet the growth needs of tobacco cultivation.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a method for preparing high-humic acid organic fertilizer for tobacco, comprising the following steps:

[0008] Select 60-70 parts of fermented and decomposed agricultural waste and 10-15 parts of peat and wood ash in equal proportions, mix them together, then crush them. After crushing, use a drying and screening device to screen them. Then add 30-40 parts of humic acid and homogenize them thoroughly. After inspection and packaging, high humic acid organic fertilizer for tobacco is obtained.

[0009] Preferably, the agricultural waste fermentation and composting material is prepared in the following manner:

[0010] Oil cake, sheep manure, cow manure, peat, and straw powder are selected as raw materials and thoroughly mixed. After mixing, water is added until the moisture content is maintained at 80%-90%. Then, a compound fermentation agent of 2% of the total solid mass is added. Fermentation is carried out in an environment of 50-60 degrees Celsius for 10-15 days. After fermentation, the material is crushed using a crushing device to a particle size of 20-30 mesh. After crushing, the material is sieved using a drying and screening device to obtain fermented and decomposed agricultural waste.

[0011] Preferably, the compound fermentation agent is one or more of Bacillus subtilis, Bacillus licheniformis and Trichoderma viride in equal proportions.

[0012] Preferably, a drying and screening device for high-humic acid smoke organic fertilizer, wherein the organic fertilizer is the high-humic acid smoke organic fertilizer described above, and the drying and screening device is the screening and drying device for high-humic acid smoke organic fertilizer described above, comprising:

[0013] A drying oven, wherein a door panel is hinged to one side of the drying oven, and the bottom of the door panel is connected to one side of the drying oven via a drive mechanism, and a heat dissipation mechanism is provided at the bottom of the drying oven;

[0014] A screening and holding mechanism is located in the middle of the drying oven;

[0015] A turning mechanism is provided inside the drying chamber and above the screening and holding mechanism.

[0016] Preferably, the drive mechanism includes an inner shaft, an outer shaft, a sector worm gear, a worm, a worm wheel assembly, a motor coil, and a wire body. The inner shaft is rotatably connected to the outer shaft. The inner shaft is connected to the worm wheel assembly, and the outer shaft is connected to the sector worm gear. The worm wheel assembly has an arc-shaped groove. A lever is fixed to the bottom of the sector worm gear, and the lever rotates within the arc-shaped groove. The top of the inner shaft is connected to the wire coil, and the wire body is wound on the wire coil. The wire coil is rotatably positioned inside the door panel. The worm gear meshes between the worm wheel assembly and the sector worm gear. The worm gear is rotatably connected to the bottom of the drying chamber. The worm gear is fixed to the drive end of the motor, and the motor is fixed to the bottom of the drying chamber.

[0017] Preferably, the screening and holding mechanism includes a shell, limiting rods, a coarse screen, a non-woven fabric mesh, and a vibrating motor. The coarse screen and the non-woven fabric mesh are respectively disposed on the upper and lower parts of the inner side of the shell. One side of the shell is connected to the production line. Both sides of the shell are provided with zigzag grooves. One end of the zigzag groove is horizontal, and the other end forms an angle of 15-30 degrees with the horizontal downward side. The horizontal downward side of the zigzag groove is located on the side of the shell away from the production line. There are two sets of limiting rods, with two rods in each set, which are respectively installed on the side wall of the drying chamber. Each set of limiting rods slides in the zigzag groove. The line connecting each set of limiting rods is horizontal, and the distance between each set of limiting rods is less than or equal to the distance of the horizontal section of the zigzag groove. A vibrating motor is provided at the end of the shell.

[0018] Preferably, the heat dissipation mechanism includes a heat dissipation box disposed at the bottom of the drying oven, a heating tube being fixed to the bottom of the heat dissipation box by a mounting base, and fan pipes for air intake being provided at both ends of the heat dissipation box.

[0019] Preferably, the flipping mechanism includes multiple flipping screens, each flipping screen having a vertical rod rotatably connected to one side of its two ends. Each vertical rod is fixed to a horizontal rod, and multiple sliders are mounted on the horizontal rod. An electric telescopic rod is fixed to the middle of the horizontal rod, and a support rod is fixed to the top of each electric telescopic rod. The support rods are installed on both sides of the top of the drying chamber. Multiple limiting grooves are provided on the upper part of both sides of the inner wall of the drying chamber, and the sliders slide within these limiting grooves. Limiting posts are slidably mounted on both sides of the support rods, and the bottom ends of these limiting posts are fixed to the horizontal rod.

[0020] Working Principle: Fermented agricultural waste is placed on a moving mesh plate, heated by heating elements, and blown into the cooling box by a fan. The hot air passes through the non-woven fabric mesh and coarse screen, then enters the rotating mesh plate, drying the fermented agricultural waste. After drying, a vibrating motor vibrates to screen the fermented agricultural waste, separating out undecomposed solids. The motor drives a worm gear and a sector wheel to open the outer shaft and the door panel. As the motor continues to rotate, the worm wheel drives a reel to wind the yarn, pulling the shell. A zigzag groove on the shell, controlled by a limiting rod, enters the horizontal downward section of the zigzag groove. This causes the shell to pull the non-woven fabric mesh and coarse screen out of the drying box. At this point, the coarse screen tilts, and the vibrating motor shakes the raw material off the screen. The fermented and decomposed agricultural waste filtered through the non-woven mesh is poured out to a location closer to the drying chamber, while the undecomposed solids on the coarse screen are poured out to a location further away. This process of using different equipment for collection achieves both drying and screening of the fermented and decomposed agricultural waste, improving its quality. During drying, an electric telescopic rod lifts the flipping screen via a crossbar. The flipping screen rotates due to weight imbalance, causing the fermented and decomposed agricultural waste to scatter onto the coarse screen, thus achieving a turning process. This facilitates drying while simultaneously achieving partial screening, mixing and spreading the raw materials. The drying and screening equipment can directly dry and screen the fermented and decomposed agricultural waste, which is more efficient than natural sun-drying and removes undecomposed solids, improving fertilizer quality.

[0021] This invention provides a method for preparing organic fertilizer for high-humic acid flue gas. It has the following beneficial effects:

[0022] 1. This invention utilizes the full composting and fermentation of oil cake, sheep manure, cow manure, peat moss, and straw powder, combined with humic acid, peat moss, and wood ash to create a compound formula. The addition of humic acid increases its content, meeting the tobacco's demand for humic acid with stable results. This results in a tobacco organic fertilizer with a humic acid content exceeding 30%. It better satisfies the tobacco's nutrient absorption and utilization needs, promotes plant growth, and improves the quality of tobacco leaves.

[0023] 2. This invention involves placing fermented agricultural waste on a movable mesh plate, heating it with heating elements, and blowing air into the heat dissipation box via a fan. The hot air passes through a non-woven fabric mesh and a coarse screen, then enters the rotating mesh plate, thus drying the fermented agricultural waste. After drying, a vibrating motor vibrates to screen the fermented agricultural waste, separating out any unfermented solids. The motor drives a worm gear and a sector wheel to open the outer shaft and the door panel. As the motor continues to rotate, the worm wheel drives a reel to wind yarn through its inner shaft, pulling the shell. When the limiting rod enters the horizontal downward part of the zigzag groove on the shell, the shell causes the non-woven fabric mesh and coarse screen to extend out of the drying box. At this point, the coarse screen tilts, and the vibrating motor shakes the raw material off the screen. The fermented and decomposed agricultural waste filtered through the non-woven mesh is poured out to a location closer to the drying chamber, while the undecomposed solids on the coarse screen are poured out to a location further away. This process of using different equipment for collection achieves both drying and screening of the fermented and decomposed agricultural waste, improving its quality. During drying, an electric telescopic rod lifts the flipping screen via a crossbar. The flipping screen rotates due to weight imbalance, causing the fermented and decomposed agricultural waste to scatter onto the coarse screen, thus achieving a turning process. This facilitates drying while simultaneously achieving partial screening, mixing and spreading the raw materials. The drying and screening equipment can directly dry and screen the fermented and decomposed agricultural waste, which is more efficient than natural sun-drying and removes undecomposed solids, improving fertilizer quality.
