Description

Technical Field

[0001] This utility model relates to the field of fertilizer processing technology, and in particular to a fertilizer storage device. Background Technology

[0002] Fertilizers, as the cornerstone of agricultural production, play a crucial role in nourishing crops and improving soil quality. They encompass ammonium phosphate fertilizers, water-soluble fertilizers rich in macronutrients, micronutrient fertilizers tailored to specific crop needs, and bio-fertilizers and organic fertilizers derived from biotechnology and organic matter. Furthermore, with technological advancements, emerging products such as multi-dimensional field energy concentrated organic fertilizers have also appeared, providing more options for agricultural production. Depending on the application scenario, fertilizers can be categorized into fertilizers suitable for field crops, household fertilizers for home gardening, garden fertilizers specifically designed for landscaping, efficient and convenient chemical fertilizers, and greening fertilizers for urban landscaping, offering diverse forms and flexible applications.

[0003] In practice, fertilizer storage is a crucial step in ensuring product quality. Traditionally, finished fertilizers are often stored directly in storage tanks, but this simple method presents numerous hidden dangers. Due to their reactive chemical properties, fertilizers readily absorb moisture from the surrounding environment, leading to frequent deliquescence and clumping. This not only increases the difficulty of discharging but can also affect fertilization efficiency due to reduced material flowability. More seriously, under long-term sealed storage conditions, the increased internal humidity of the fertilizer provides a breeding ground for microorganisms, accelerating the mold growth process and severely damaging its quality and efficacy, ultimately impacting crop growth and yield. Utility Model Content

[0004] This utility model discloses a fertilizer storage device that solves the problem that existing fertilizers easily absorb moisture during storage, leading to clumping and mold growth, which affects the quality and efficacy of the fertilizer.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A fertilizer storage device includes a vertically arranged cylinder. An inlet pipe and an outlet pipe are connected to the top and bottom of the cylinder, respectively. A cover plate is hinged to the inlet pipe. An electrically controlled valve is installed inside the cylinder to block the outlet pipe. A first stirring shaft, coaxial with and vertically aligned with the cylinder, is rotatably connected inside the cylinder. Several second stirring shafts, each surrounding and parallel to the first stirring shaft, are also rotatably connected inside the cylinder. Several stirring paddles are fixed to the surfaces of both the first and second stirring shafts. A horizontal first gear is fixed to the top surface of the first stirring shaft, and second gears meshing with the first gear are fixed to the top surfaces of the several second stirring shafts. A motor for driving the first stirring shaft to rotate around its own axis is provided at the top of the cylinder. A dehumidification mechanism for removing moisture from the cylinder is also provided on the cylinder.

[0007] Compared with the prior art, the present invention has the following beneficial effects:

[0008] After opening the cover and pouring the finished fertilizer into the cylinder through the feed pipe, close the cover. At this point, due to the cover and the electrically controlled valve, the cylinder forms a sealed structure, effectively preventing external moisture from entering the cylinder through the feed and discharge pipes. Subsequently, start the motor. The motor's output drives the first stirring shaft to rotate around its own axis, which in turn drives several second stirring shafts to rotate around their own axes in the opposite direction to the first stirring shaft via the first and second gears. This causes the fertilizer in the cylinder to form multiple mixed flows, effectively ensuring good fluidity of the fertilizer in the cylinder and preventing it from clumping. At the same time, a dehumidification mechanism is also provided to remove moisture from the cylinder. Combined with the stirring action of the first and several second stirring shafts, the moisture in the fertilizer can be fully removed, ensuring the dryness of the fertilizer during storage and thus avoiding the possibility of mold growth.

[0013] The specific content of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0014] like Figure 1 and Figure 2 As shown, this utility model provides a fertilizer storage device, including a vertically arranged cylinder 1. The top and bottom ends of the cylinder 1 are respectively connected to an inlet pipe 2 and an outlet pipe 3. A cover plate 21 is hinged to the inlet pipe 2. An electrically controlled valve 31 is provided inside the cylinder 1 to block the outlet pipe 3. A first stirring shaft 4, coaxial with and vertical to the cylinder 1, is rotatably connected inside the cylinder 1. Several second stirring shafts 43, which surround the first stirring shaft 4 and are parallel to the first stirring shaft 4, are also rotatably connected inside the cylinder 1. Several stirring paddles 41 are fixed on the surfaces of the first stirring shaft 4 and the second stirring shaft 43. A horizontal first gear 44 is fixed on the top surface of the first stirring shaft 4. A second gear 45 that meshes with the first gear 44 is fixed on the top surface of the several second stirring shafts 43. A motor 42 is provided at the top of the cylinder 1 to drive the first stirring shaft 4 to rotate around its own axis. A dehumidification mechanism is also provided on the cylinder 1 to remove moisture from the cylinder 1. Furthermore, the second stirring shaft 43 is preferably set to four, so that the fertilizer product in the cylinder 1 can be stirred more thoroughly.

[0015] like Figure 1 and Figure 2As shown, the dehumidification mechanism includes a dehumidification box 5 fixed to the bottom of the cylinder 1. The bottom ends of the first stirring shaft 4 and several second stirring shafts 43 all penetrate the cylinder 1 and extend into the dehumidification box 5. The bottom ends of the first stirring shaft 4 and several second stirring shafts 43 are all open and connected to the dehumidification box 5. Several holes are opened on the surface of the first stirring shaft 4 and several second stirring shafts 43. Several ventilation holes 51 are opened at the bottom of the dehumidification box 5. A horizontal activated carbon adsorption plate 52 is provided inside the dehumidification box 5. A support frame 53 located above the activated carbon adsorption plate 52 is fixed inside the dehumidification box 5. A suction fan 531 is provided on the support frame 53. An electric heating mesh plate 54 located above the suction fan 531 and horizontally fixed inside the dehumidification box 5 is also fixed inside the dehumidification box 5. The suction fan 531 and the electric heating mesh plate 54 are activated. The suction fan 531 draws outside air into the dehumidification box 5 through the ventilation hole 51. The activated carbon adsorption plate 52 adsorbs the moisture in the air, reducing the humidity of the drawn-in air. The dehumidified air is heated to a suitable temperature by the electric heating mesh plate 54, and then evenly transported into the interior of the cylinder 1 through the holes on the surface of the first stirring shaft 4 and several second stirring shafts 43. In this way, the fertilizer product can be stirred by the first stirring shaft 4 and several second stirring shafts 43, and the moisture in the fertilizer can be fully removed, effectively ensuring the dryness of the fertilizer during storage and thus avoiding the possibility of mold.

[0016] like Figure 1 and Figure 2 As shown, horizontal slide rails 521 are fixed on the inner walls of both sides of the dehumidification box 5, and the two slide rails 521 are slidably connected to the two sides of the activated carbon adsorption plate 52 respectively; a door 55 is hinged to the surface of the dehumidification box 5. The slide rails 521 allow the operator to install and remove the activated carbon adsorption plate 52; the door 55 allows the operator to easily open the dehumidification box 5, thereby enabling the inspection and maintenance of the suction fan 531 and the electric heating mesh plate 54 inside the dehumidification box 5, as well as the replacement of the activated carbon adsorption plate 52.

[0017] like Figure 1 , Figure 2 and Figure 3 As shown, the dehumidification mechanism also includes an exhaust pipe 6 connected to the top of the cylinder 1. An exhaust fan 61 is installed inside the exhaust pipe 6, and a dust filter 62 is installed at the end of the exhaust pipe 6 away from the cylinder 1. The dust filter 62 is detachably connected to the exhaust pipe 6 by bolts 63. Hot air drawn into the cylinder 1 is discharged through the exhaust pipe 6. The exhaust fan 61 accelerates the circulation of hot air, thereby accelerating the removal of internal moisture and improving dehumidification efficiency. The dust filter 62 prevents dust and other fine particles in the air from entering the exhaust fan 61, ensuring its continuous and stable operation and extending its service life. The bolts 63 facilitate the removal and cleaning of the dust filter 62 by personnel.

[0018] like Figure 2As shown, several stirring blades 41 on each second stirring shaft 43 are alternately arranged with the corresponding stirring blades 41 on the first stirring shaft 4, which can prevent the stirring blades 41 on the second stirring shaft 43 and the first stirring shaft 4 from interfering with each other, and also facilitates the cross-flow of fertilizer in the cylinder 1.

[0019] like Figure 1 As shown, the cylinder 1 is equipped with a control panel 11, and the electrically controlled valve 31, motor 42, suction fan 531, electric heating mesh plate 54, and exhaust fan 61 are all electrically connected to the control panel 11. The control panel 11 facilitates the use and adjustment of the entire device by the operator.

[0020] like Figure 1 As shown, an observation window 12 is provided on the surface of the cylinder 1; a handle 22 is fixed on the cover plate 21. The observation window 12 allows staff to easily observe the storage status of fertilizer inside the cylinder 1 in real time; the handle 22 allows staff to easily open or close the cover plate 21.

[0021] like Figure 1 As shown, several support legs 7 are fixed to the bottom of the cylinder 1. The support legs 7 can fix and support the entire device.

[0022] In use, open the cover plate 21 using handle 22, pour the finished fertilizer into the cylinder 1 through the feed pipe 2, and then close the cover plate 21. At this time, due to the setting of the cover plate 21 and the electric control valve 31, the cylinder 1 forms a sealed structure, effectively preventing external moisture from entering the cylinder 1 through the feed pipe 2 and the discharge pipe 3. Subsequently, start the motor 42. The output end of the motor 42 drives the first stirring shaft 4 to rotate around its own axis, which in turn drives several second stirring shafts 43 to rotate around their own axes in the opposite direction to the first stirring shaft 4 through the first gear 44 and the second gear 45. This causes the fertilizer in the cylinder 1 to form multiple mixed flows, effectively ensuring the good fluidity of the fertilizer in the cylinder 1, so that the fertilizer does not... It is prone to clumping; then, the suction fan 531 and the electric heating mesh plate 54 are turned on. The suction fan 531 draws the outside air into the dehumidification box 5 through the ventilation hole 51. The activated carbon adsorption plate 52 can adsorb the moisture in the air, reducing the humidity of the drawn-in air. The dehumidified air is heated to an appropriate temperature under the action of the electric heating mesh plate 54. Finally, it is evenly transported into the interior of the cylinder 1 through the holes on the surface of the first stirring shaft 4 and several second stirring shafts 43. In this way, the fertilizer product can be stirred by the first stirring shaft 4 and several second stirring shafts 43, and the moisture in the fertilizer can be fully removed, effectively ensuring the dryness of the fertilizer during storage, thereby avoiding the possibility of mold.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
