Description

Technical Field

[0001] The invention relates to the technical field of fertilizer production, in particular to a production process of an organic trace element chelated effervescent fertilizer. Background Art

[0002] Chelated fertilizer is a fertilizer that chelates various elements together through a unique production method. Chelates are chemically called complexes, which are composed of a large ligand connected to a central metal atom to form a ring structure. Chelating agents (or ligands) can chelate with metal ions. This effect enables chelating agents to selectively capture certain metal ions in plant cells and release them in appropriate amounts when necessary, thereby promoting the absorption of nutrients by crops. Chelated trace element fertilizers are better than inorganic trace element fertilizers. They are not easily fixed in the soil, are easily soluble in water, and do not dissociate. They can be well absorbed and utilized by plants. They can also be mixed with other solid or liquid fertilizers for application without chemical reactions, and without reducing the fertilizer efficiency of any fertilizer.

[0003] Effervescent fertilizer is a highly efficient and environmentally friendly fertilizer, mainly composed of starch, protein, carbonate, nitrogen, phosphorus and potassium. Its working principle is to release heat and gas through acid-base reaction, and use the rupture of carbon dioxide bubbles to accelerate the disintegration of fertilizer to achieve the purpose of loosening the soil. Effervescent fertilizer quickly decomposes in water to produce bubbles, which can penetrate into the soil, improve soil aeration and water retention, increase the oxygen content in the soil, and promote the growth and reproduction of microorganisms.

[0004] Combining effervescent fertilizer with chelated fertilizer can further improve the absorption and utilization rate of chelated fertilizer.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0027] According to the following Figure 1-Figure 16 The present invention describes a production process of an organic trace element chelated effervescent fertilizer provided by an embodiment of the present invention.

[0028] Embodiment 1, this embodiment refers to Figure 1-Figure 9 .

[0029] like Figure 1 The embodiment of the present invention provides a production process of an organic trace element chelated effervescent fertilizer, comprising the following steps: S1: selecting an organic trace element compound, dissolving the organic trace element compound in an appropriate amount of water to form a uniform solution, and adding a chelating agent to the formed solution to complete chelation of the organic trace element solution; S2 dries and crushes the crystals formed after chelation to form raw material powder 1; S3: uniformly mixing the raw material powder 1, the powdered effervescent fertilizer raw material, the powdered solid organic acid, the powdered alkali source and the surfactant in proportion to form a granulation raw material; S4 uses an extrusion granulation method to prepare granular effervescent fertilizer from the granulation raw materials.

[0030] Preferably, the chelating agent here is a high-purity organic acid substance, such as acetic acid, internal acid, etc.

[0031] Effervescent agents use organic acids (such as citric acid, tartaric acid, etc.) and carbonates (such as sodium carbonate, sodium bicarbonate, etc.). Organic acids provide an acidic environment and react with carbonates to produce carbon dioxide gas, thereby achieving the effervescent effect.

[0032] The above process requires the use of a mixing reactor, a drying device, a crushing device, a powder mixing device and a granulating device. The mixing reactor is used for chelating the organic trace element solution, the drying device is used for drying the crystals formed after chelation in S2, the crushing device is used for crushing the dried crystals in S2, the powder mixing device is used for mixing the raw material powder, powdered effervescent fertilizer raw material, powdered solid organic acid, powdered alkali source and surfactant; the granulating device is used for granulating the granulation raw material.

[0033] Combination Figure 2 and Figure 3 As shown, the powder mixing equipment includes a U-shaped bracket 1, a mixing tank 3 and a transposition shaft 5. The mixing tank 3 serves as a mixing place for raw material powder 1, powdered effervescent fertilizer raw material, powdered solid organic acid, powdered alkali source and surfactant, and includes a single tank 31, a tail box 33 and a rotating shaft 35.

[0034] At least two single tanks 31 are provided, and an angle is formed between the two single tanks 31. The tail box 33 is provided at one end of the single tank 31 forming the angle. One end of the rotating shaft 35 is rotatably mounted on the U-shaped bracket 1 through a bearing, and the other end of the rotating shaft 35 is fixed to the outer side of the single tank 31 for driving the single tank 31 to rotate. The rotation of the single tank 31 can make the material in the single tank 31 enter the tail box 33, and can also make the material in the tail box 33 enter the single tank 31. When the single tank 31 rotates to the upper side, the material in the single tank 31 enters the tail box 33. When the tail box 33 rotates to the upper side, the material in the tail box 33 is separated and enters the single tank 31. The material is repeatedly separated to achieve the purpose of uniform mixing.

[0035] In this embodiment, two single tanks 31 are provided, and the two single tanks 31 form a V-shaped structure. Figure 2 and Figure 3 .

[0036] The V-shaped mixing device in the prior art only relies on the above-mentioned rotation to achieve mixing, but in fact the path of the material in the single tank 31 entering the tail box 33 remains unchanged. Figure 4Most of the materials in the single tank 31 on the left will fall to the left side of the tail box 33, and a small part will fall to the right side of the tail box 33. Similarly, most of the materials in the single tank 31 on the right will fall to the right side of the tail box 33, and a small part will fall to the left side of the tail box 33. As a result, after the tail box 33 rotates to the top, the materials on the left side will still return to the single tank 31 on the left, and the materials on the right side will still return to the single tank 31 on the right, reducing the mixing efficiency.

[0037] For this purpose, the embodiment of the present invention also provides a transposition axis 5, referring to Figure 3 and Figure 5 The transposition shaft 5 is located at the angle formed by the two single tanks 31, and the transposition shaft 5 is inserted into the tail box 33. Transposition blades 51 are provided on both sides of the part of the transposition shaft 5 located in the tail box 33. The transposition blades 51 and the inner wall of the tail box 33 form a chamber, and the chamber is used to receive the material from the single tank 31. The rotation of the transposition shaft 5 can adjust the relative position of the chamber and the single tank 31 to force the change of the material discharge direction in the chamber.

[0038] by Figure 3 and Figure 4 Taking the state shown in FIG. 1 as an example, the transposition blade 51 is perpendicular to the connecting line of the single tank 31. At this time, two chambers are formed on both sides of the transposition blade 51 (such as Figure 6 As shown in the state, the left chamber is used to receive most of the materials falling from the left single tank 31, and the right chamber is used to receive most of the materials falling from the right single tank 31. As the rotating shaft 35 rotates, the tail box 33 gradually rotates to the top, and the transposition shaft 5 also rotates at this time, so that the transposition blade 51 is parallel to the connecting line of the two single tanks 31 (as shown in the state shown in the state). Figure 7 As shown in the state, part of the materials in the two chambers are opposite to the single tank 31 on the left, and the other part is opposite to the single tank 31 on the right, so that the materials in each chamber can be evenly divided into the two single tanks 31, thereby achieving the purpose of forcibly changing the direction of the materials in the chamber being discharged into the single tank 31, improving the mixing uniformity and improving the mixing efficiency.

[0039] Combination Figure 2 and Figure 3 As shown, in order to achieve the purpose of rotating the transposition shaft 5 when the tail box 33 gradually rotates to the upper side, a transposition drive assembly 4 is also provided. The transposition drive assembly 4 includes a first gear ring 42, an L-shaped bracket 46, a traveling gear 44 and a long shaft 47.

[0040] Specifically, a fixed inner cylinder 43 is provided in the first gear ring 42 through spokes, and the fixed inner cylinder 43 is fixed to the U-shaped bracket 1 through the side frame 12, so that the first gear ring 42 is in a fixed state. In addition, the first gear ring 42 is located on one side of the mixing tank 3 and is coaxial with the rotating shaft 35. The first gear ring 42 is rotatably connected to the rotating shaft 35 through a bearing or the first gear ring 42 and the rotating shaft 35 are clearance-matched. In short, the first gear ring 42 does not rotate with the rotating shaft 35.

[0041] One end of the L-shaped bracket 46 is fixed to the rotating shaft 35, the upper end of the transposition shaft 5 is rotatably mounted on the upper end of the L-shaped bracket 46 through a bearing, the traveling gear 1 44 is rotatably mounted on the L-shaped bracket 46 through a bearing, and the traveling gear 1 44 is meshed with the first gear ring 42, the long shaft 47 is rotatably mounted on the L-shaped bracket 46 through a bearing, an active bevel wheel 48 is mounted on the end of the long shaft 47 close to the transposition shaft 5, a driven bevel wheel 49 meshed with the active bevel wheel 48 is provided on the upper end of the transposition shaft 5, and a belt transmission structure 45 is provided between the end of the long shaft 47 away from the transposition shaft 5 and the traveling gear 1 44.

[0042] In the present embodiment, when the rotating shaft 35 rotates, it can drive the single tank 31 and the tail box 33 to rotate. At the same time, the L-shaped bracket 46 rotates accordingly. During the rotation, the traveling gear 44 travels on the first gear ring 42, so that the traveling gear 44 can rotate by itself. During its rotation, it can drive the long shaft 47 to rotate through the belt transmission structure 45. During the rotation of the long shaft 47, the driven umbrella wheel 49 can be driven to rotate through the active umbrella wheel 48. When the driven umbrella wheel 49 rotates, the transposition shaft 5 rotates.

[0043] Preferably, the first toothed ring 42 is substantially an incomplete toothed ring, referring to Figure 3 and Figure 8 , Figure 8 (a) Figure 3 The left side view of the first gear ring 42 in the state shown has no teeth on the upper and lower sides and has teeth on both horizontal sides. Figure 8 In the (a) state, the single tank 31 is located at the top, the tail box 33 is located at the bottom, and all the materials are located in the tail box 33. As the single tank 31 gradually rotates downward, the running gear 44 first passes through the toothless part above. At this time, the transposition shaft 5 does not rotate, and the transposition blade 51 maintains Figure 6 In the state shown in FIG. 1 , when the running gear 1 44 passes through the toothed portion on the right side, as shown in FIG. Figure 8 (b), at this time, the transposition shaft 5 rotates, and the transposition blade 51 is Figure 6 The state shown is formed Figure 7 The state shown in FIG. 1 is shown in FIG. 1 , and then the traveling gear 1 44 passes through the toothless portion below, as shown in FIG. Figure 8 (c), and at this time, the single tank 31 rotates downward, the tail box 33 rotates upward, and the transposition blade 51 maintains Figure 7 In the state shown, the material in the chamber can be dispersed into the two single tanks 31, and as the single tanks 31 gradually rotate upward, the running gear 44 passes through the toothed portion on the left side, as shown in FIG. Figure 8 (d), at this time, the transposed blade 51 rotates again to form Figure 6 In the state shown, the two side chambers receive the materials in the two single tanks 31 respectively.

[0044] Preferably, a second outer cover 11 is further provided outside the first gear ring 42 to shield the traveling gear 1 44 .

[0045] like Fig. 9 In order to realize the rotation of the rotating shaft 35, a mixing main drive component 9 is also provided here. The mixing main drive component 9 is installed on one side of the U-shaped bracket 1 and is used to drive the rotating shaft 35 to rotate. It includes a servo motor and a reducer. The servo motor drives the rotating shaft 35 to rotate after being reduced in speed.

[0046] In addition, a control panel 2 is provided on the outer surface of the U-shaped bracket 1 for controlling the operation of the servo motor.

[0047] When in use (working), the servo motor drives the rotating shaft 35 to rotate. When the rotating shaft 35 rotates, the tail box 33 and the single tank 31 can rotate synchronously with the rotating shaft 35, so that the materials in the tail box 33 can gradually enter the single tank 31. At the same time, the rotating shaft 35 can drive the L-shaped bracket 46 to rotate accordingly. During the rotation, the walking gear 44 walks on the first gear ring 42. When it reaches the toothed part, the walking gear 44 can rotate by itself. During its rotation, it can drive the long shaft 47 to rotate through the belt transmission structure 45. During the rotation of the long shaft 47, the driven umbrella wheel 49 can be driven to rotate through the active umbrella wheel 48. When the driven umbrella wheel 49 rotates, the transposition shaft 5 rotates. The rotation of the transposition shaft 5 can drive the transposition blade 51 to rotate. When the transposition blade 51 rotates, the materials in each chamber in the tail box 33 can be dispersed into each single tank 31, thereby improving the uniformity of mixing and preventing the materials from moving back and forth in the tail box 33 and the single tank 31 along an unchanged path.

[0048] Embodiment 2, this embodiment refers to Figure 10-Figure 16 .

[0049] like Figure 10-12 As shown, the difference between this embodiment and the first embodiment is that there are three single tanks 31 here, and the three single tanks 31 form an umbrella structure. Compared with the two single tanks 31 in the first embodiment, the three single tanks 31 can divide the material in the tail box 33 into more portions, thereby improving the mixing efficiency.

[0050] However, in fact, when three single tanks 31 are provided, the three single tanks 31 are not on the same plane as the two single tanks 31 in the first embodiment. Fig.13 For better understanding, Fig.13 This is the entire flow chart of the rotation of three single tanks 31 in this embodiment. Fig.13 (b)- Fig.13 During the process (f), the materials in the tail box 33 gradually enter the single tank 31. In this process, it can be seen from the figure that in fact, most of the materials will enter the single tank 31 at the bottom, that is, they will enter Fig.13(c) In the bottom single tank 31-1, this results in different amounts of material entering each single tank 31, affecting the mixing, so here the three single tanks 31 are designed to be able to revolve along the tail box 33, so that the three single tanks 31 alternately become the bottom single tank 31, thereby ensuring that the amount of material in each single tank 31 is the same.

[0051] Specifically, refer to Fig.12 and Fig.14 As shown, the single tank 31 in this embodiment includes an outer tank 313, and the three outer tanks 313 are an integrated structure. The lower ends of the three outer tanks 313 are provided with an extension tube 1 314, and the upper end of the tail box 33 is provided with an extension tube 2 331. The extension tube 1 314 is rotatably installed in the extension tube 2 331; the rotating shaft 35 is provided with a revolution drive component 6 for driving the outer tank 313 to revolve around the center of the tail box 33.

[0052] Combination Fig.14 and Fig.16 As shown, preferably, at least two groups of limiting rings 1 315 are arranged on the outer wall of the extension tube 1 314, and a limiting ring 2 332 is arranged on the inner wall of the extension tube 2 331, and the space between the two groups of limiting rings 1 315 forms a limiting groove, and the limiting ring 2 332 is located in the limiting groove to limit the outer tank 313 from falling off from the tail box 33. Furthermore, a bearing is arranged between the limiting ring 1 315 and the tail box 33.

[0053] Reference Fig.12 and Fig.15 As shown, the revolution driving assembly 6 includes an outer ring gear 61 , a first gear 62 and a rack 64 .

[0054] Specifically, the outer gear ring 61 is fixed to the outside of the circumference of the extension tube 314, the first gear 62 is rotatably installed on the rotating shaft 35 through the central axis, and the first gear 62 is meshed with the outer gear ring 61, and the other side of the first gear 62 is meshed with the second gear 63, and the rack 64 is fixed to the U-shaped bracket 1 through the side frame 66, and a coaxial traveling bevel wheel 68 is fixed above the second gear 63, and the traveling bevel wheel 68 is meshed with the rack 64.

[0055] Preferably, a first outer cover 10 is further provided outside the rack 64 to shield the traveling bevel wheel 68 , the first gear 62 and the second gear 63 .

[0056] In this embodiment, when the single tank 31 and the tail box 33 rotate with the rotating shaft 35, the rotating shaft 35 can also drive the walking umbrella wheel 68 to move on the gear track 64, so that the walking umbrella wheel 68 can rotate, and its rotation can drive the second gear 63 to rotate, and then achieve the purpose of the first gear 62 driving the outer ring gear 61 to rotate, and when the outer ring gear 61 rotates, the single tank 31 can revolve.

[0057] In order to improve the mixing efficiency of the materials in the single tank 31, the single tank 31 here also includes an inner tank 312, which is rotatably mounted in the outer tank 313. A head 311 is fixedly arranged at the upper end of the inner tank 312, and an outer cylinder 41 is fixedly arranged below one end of the L-shaped bracket 46 close to the transposition shaft 5. The outer cylinder 41 revolves with the single tank 31, and a main driving umbrella wheel 8 is installed on the outer cylinder 41. A self-rotating umbrella wheel 7 capable of meshing with the main driving umbrella wheel 8 is fixedly arranged on the outer circumference of the inner tank 312. When the inner tank 312 revolves, the self-rotating umbrella wheel 7 can move on the main driving umbrella wheel 8, so that the self-rotating umbrella wheel 7 can rotate, and its rotation can drive the inner tank 312 to rotate, so that the inner tank 312 can also rotate when it revolves along the center of the circle of the tail box 33. When the inner tank 312 rotates, the materials inside it can be forced to be mixed, thereby improving the mixing efficiency. Compared with the method of assembling the stirring shaft in the single tank 31 in the prior art, this method of rotating the single tank 31 can prevent the materials from sticking to the stirring shaft.

[0058] Preferably, a sealing cover 32 is installed at the upper end of the single tank 31, and a butterfly valve 34 is provided at the lower end of the tail box 33. By controlling the opening and closing of the butterfly valve 34, the discharge or non-discharge of the powder mixing equipment can be achieved.

[0059] It should be noted that the transposition blades 51 in this embodiment are arranged in three groups, and the first tooth ring 42 is arranged to be fully toothed, so that the transposition blades 51 are continuously transposed, so that the same chamber can receive materials in different single tanks 31, and when the chamber feeds materials to the single tank 31, it can feed materials to different single tanks 31, thereby further improving the mixing efficiency.

[0060] When in use (working), the servo motor drives the rotating shaft 35 to rotate. When the rotating shaft 35 rotates, the tail box 33 and the single tank 31 can rotate synchronously with the rotating shaft 35, so that the materials in the tail box 33 can gradually enter the single tank 31. At the same time, the rotating shaft 35 can drive the L-shaped bracket 46 to rotate accordingly. During the rotation, the walking gear 44 walks on the first gear ring 42, so that the walking gear 44 can rotate by itself. During its rotation, the long shaft 47 can be driven to rotate through the belt transmission structure 45. During the rotation of the long shaft 47, the driven umbrella wheel 49 can be driven to rotate through the active umbrella wheel 48. When the driven umbrella wheel 49 rotates, the transposition shaft 5 rotates. The rotation of the transposition shaft 5 can drive the transposition blade 51 to rotate. When the transposition blade 51 rotates, the position of the chamber can be adjusted, so that the materials in the chamber can be dispersed into each single tank 31. At the same time, when the single tank 31 and the tail box 33 rotate with the rotating shaft 35, the rotating shaft 35 can also drive the walking umbrella wheel 68 to move on the rack 64 When the outer gear ring 61 rotates, the single tank 31 can be made to revolve, and the single tank 31 can continuously change its position when revolving, so as to ensure that the amount of materials entering each single tank 31 from the tail box 33 is the same, and to ensure that the materials in each single tank 31 can be evenly distributed in each chamber in the tail box 33. In addition, when the single tank 31 revolves, the self-rotating umbrella wheel 7 can walk on the main driving umbrella wheel 8, so that the self-rotating umbrella wheel 7 can rotate, and its rotation can drive the inner tank 312 to rotate, so that the inner tank 312 can also rotate when it revolves along the center of the tail box 33, and the materials inside the inner tank 312 can be forced to mix when it rotates, thereby improving the mixing efficiency. Compared with the method of assembling the stirring shaft in the single tank 31 in the prior art, this method of rotating the single tank 31 can prevent the materials from sticking to the stirring shaft.
