Description

Technical Field

[0001] This invention relates to the field of fertilizer and additive mixing equipment, and more specifically to a reaction vessel for dual mixing of fertilizer and additives. Background Technology

[0002] Chemical fertilizers, also known as organic fertilizers, are fertilizers made using chemical or physical methods that contain one or more nutrients needed for crop growth. They are also called inorganic fertilizers and include nitrogen fertilizers, phosphorus fertilizers, potassium fertilizers, micronutrient fertilizers, and compound fertilizers. They share some common characteristics: simple composition and high nutrient content; rapid and potent fertilizer effect; some fertilizers react with acids and alkalis; generally do not contain organic matter and do not improve soil quality or fertilize the soil.

[0003] Fertilizer adjuvants, or simply adjuvants, are non-plant mineral nutrients and non-hormonal auxiliary substances added during fertilizer production. They do not directly provide nutrients to crops, but they can significantly improve the physicochemical properties of fertilizers, increase fertilizer utilization efficiency, and reduce environmental risks.

[0004] Calcium magnesium phosphate (MgMg) fertilizer is one of the most widely used phosphate fertilizers in my country. It is formed by melting phosphate rock and dolomite / serpentine at 1350℃~1500℃, followed by water quenching and rapid cooling. MgMg has high hardness, a smooth, hydrophobic, glassy surface, and no capillaries, making it difficult to adsorb other particles and prone to uneven mixing. Magnesium oxide and dolomite are common additives, both used for pH adjustment; dolomite also helps prevent localized over-alkalinity. In recent years, with technological upgrades in the fertilizer industry, both fertilizers and additives have been upgraded to granular form, which can improve the uniformity of mixing to some extent. However, the amount of magnesium oxide and dolomite added is relatively small, and their density is greater than that of MgMg phosphate. Furthermore, existing mixing devices typically only stir in the center of the device, making it difficult to mix fertilizers and additives evenly. Summary of the Invention

[0005] To address the above shortcomings, the present invention provides a reaction vessel for dual mixing of fertilizers and additives. This reaction vessel can achieve simultaneous stirring at the center and edge, so that the fertilizers and additives are mixed evenly.

[0006] This invention protects a reaction vessel for dual mixing of fertilizer and additives, wherein the fertilizer and the additives are collectively referred to as materials. The reaction vessel includes a vessel body, and a main stirring component capable of stirring is provided at the center of the vessel body. The main stirring component drives a secondary stirring component through a transmission component, so that the secondary stirring component can rotate to stir the materials while simultaneously revolving around the main stirring component to stir the materials. The auxiliary stirring component can also lift the material at the bottom of the vessel to the top of the vessel, thereby achieving vertical mixing of the material.

[0007] Furthermore, the main stirring assembly includes a main shaft and main stirring blades fixed to the side wall of the main shaft; The auxiliary stirring assembly includes a hollow auxiliary shaft and auxiliary stirring blades fixed on the outer wall of the auxiliary shaft. The auxiliary shaft is provided with a lifting shaft, and the outer wall of the lifting shaft is provided with spiral blades for lifting materials.

[0008] Furthermore, the transmission assembly includes a first main gear fixed on the main shaft, a first secondary gear fixed on the secondary shaft, and an internal gear ring fixed on the inner wall of the vessel. The first main gear is located at the center of the internal gear ring, and the first main gear meshes with the internal gear ring through the first secondary gear.

[0009] Furthermore, the transmission assembly includes a second main gear fixed on the main shaft, a second auxiliary gear fixed on the lifting shaft, and a support plate; One end of the bearing plate is rotatably sleeved on the main shaft, and the other end of the bearing plate is rotatably sleeved on the auxiliary shaft. A transmission shaft is also rotatably mounted on the bearing plate, and a transmission gear is fixed at the top of the transmission shaft. The two sides of the transmission gear mesh with the second main gear and the second auxiliary gear, respectively.

[0010] Furthermore, the bottom diameter of the secondary shaft is larger than the top diameter of the secondary shaft, which accelerates the upward flow of the material inside the hollow structure and enhances the mixing effect.

[0011] Furthermore, it also includes an airflow assembly, which is driven by the main stirring assembly to allow airflow to exit from the top of the vessel and enter from the bottom of the vessel, thereby achieving airflow circulation, increasing the disturbance of the material, and enhancing the mixing effect.

[0012] Furthermore, the top of the vessel body is provided with a top through hole, and the bottom of the vessel body is provided with a bottom through hole; The airflow assembly includes blades, pipes, dustproof plates, and exhaust columns; The blades are fixed on the main stirring assembly and positioned above the transmission assembly, allowing the airflow to flow upwards into the top through hole. The pipe is fixed to the outside of the vessel body and connects the top through hole and the bottom through hole; The dustproof plate is rotatably mounted on the main stirring assembly and the auxiliary stirring assembly, and is located below the transmission assembly to block dust generated by the material. The exhaust column covers the bottom through hole and is used to discharge gas.

[0013] Furthermore, the edge of the dustproof plate is provided with a bent portion, and a curved channel is formed between the bent portion and the inner wall of the vessel body to prevent dust from entering; The exhaust column includes a column body and a conical cap disposed at the top of the column body. The side wall of the column body is provided with a side through hole for exhausting air, and the lower edge of the conical cap is lower than the side through hole.

[0014] Furthermore, it also includes a vibration component disposed on the bottom surface of the vessel body, which vibrates as the auxiliary stirring component moves closer to or away from the vessel body to prevent material bridging.

[0015] Furthermore, the vibration assembly includes a housing and a first magnet. The length direction of the housing is arranged along the revolution direction of the auxiliary stirring assembly. A swing arm is provided inside the housing. The midpoint of the swing arm is rotatably arranged on the inner wall of the housing via a rotating shaft. Impact blocks are provided at both ends of the swing arm, and a second magnet is provided inside the impact blocks. The first magnet is fixed to the bottom of the auxiliary stirring assembly. The magnetic force between the first magnet and the second magnet causes the swing arm to swing, which in turn drives the impact block to strike the outer shell and generate vibration.

[0016] Beneficial Effects: This invention, by setting a main stirring component, enables stirring at the center of the vessel, mixing the materials in that central position. By setting a secondary stirring component, firstly, the secondary stirring component can rotate around the axis of the main stirring component, i.e., it revolves. During this revolution, it mixes the materials at the outer periphery of the vessel, working in conjunction with the main stirring component's stirring at the center to ensure thorough mixing of materials at different locations. Secondly, the secondary stirring component can rotate on its own axis, providing a stirring effect. Furthermore, since the secondary stirring component is driven by the main stirring component, a speed difference exists between the two components, resulting in more uniform stirring of materials at different positions and speeds. The secondary stirring component in this invention can also lift materials from the bottom of the vessel to the top, allowing the materials to move vertically, breaking the laminar flow of the materials and ensuring thorough mixing.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. 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 of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0020] refer to Figures 1-14 This invention discloses a reaction vessel for dual mixing of fertilizer and additives, wherein fertilizer and additives are collectively referred to as materials. The reaction vessel includes a vessel body 1, with a feed inlet 13 on its side for adding materials. A main stirring assembly 2 is located at the center of the vessel body 1. The main stirring assembly 2 drives a secondary stirring assembly 4 via a transmission assembly 3, enabling the secondary stirring assembly 4 to rotate and stir the materials while simultaneously revolving around the main stirring assembly 2. Revolving refers to the secondary stirring assembly 4 rotating around the axis of the main stirring assembly 2.

[0021] The auxiliary stirring component 4 can also lift the material at the bottom of the vessel 1 to the top of the vessel 1, achieving vertical mixing of the material. The auxiliary stirring component 4 is also driven by the main stirring component 2 to lift the material. (Reference) Figure 2 The material enters from the bottom of the auxiliary stirring component 4 and exits from the top of the auxiliary stirring component 4, thus achieving vertical mixing of the material.

[0022] This invention, by setting a main stirring component 2, enables stirring at the center of the vessel 1, mixing the materials at that center. By setting a secondary stirring component 4, firstly, the secondary stirring component 4 can rotate around the axis of the main stirring component 2, i.e., it revolves. During this revolution, it can mix the materials at the outer periphery of the vessel 1, working in conjunction with the main stirring component 2 to ensure thorough mixing of materials at different locations. Secondly, the secondary stirring component 4 can rotate on its own axis, providing a stirring effect. Furthermore, since the secondary stirring component 4 is driven by the main stirring component 2, there is a speed difference between the two components, resulting in more uniform mixing of materials at different locations and speeds. The secondary stirring component 4 in this invention can also lift materials from the bottom of the vessel 1 to the top, allowing the materials to move vertically, breaking the laminar flow of the materials and ensuring thorough mixing.

[0023] refer to Figure 3 , Figure 5 , Figure 7 and Figure 14 In one specific embodiment, the main stirring assembly 2 includes a main shaft 22 and main stirring blades 21 fixed to the side wall of the main shaft 22. The angle between the main stirring blades 21 and the horizontal plane is an acute angle, preferably 45°. When the main shaft 22 rotates, the main stirring blades 21 can stir the material simultaneously in the vertical and horizontal directions, thereby improving the stirring effect.

[0024] The auxiliary stirring assembly 4 includes a hollow auxiliary shaft 43 and auxiliary stirring blades 44 fixed to the outer wall of the auxiliary shaft 43. The auxiliary stirring blades 44 are vertically arranged, and the plane in which the auxiliary stirring blades 44 are located is perpendicular to the horizontal plane. The rotation of the auxiliary shaft 43 causes the auxiliary stirring blades 44 to stir the material only in the horizontal direction. A lifting shaft 41 is provided inside the auxiliary shaft 43, and a spiral blade 42 is fixed to the outer wall of the lifting shaft 41 for lifting the material. The rotation of the auxiliary shaft 43 drives the auxiliary stirring blades 44 to stir the material; at the same time, the rotation of the lifting shaft 41 drives the spiral blades 42 to spiral upward and lift the material.

[0025] This embodiment incorporates a secondary stirring assembly 4, where the secondary stirring blade 44 stirs the material horizontally only, and the spiral blade 42 lifts the material vertically. The advantages are: First, the two components do not interfere with each other. The secondary stirring blade 44 only stirs horizontally, and the spiral blade 42 only lifts the material; their actions on the material are in different directions, thus avoiding mutual interference and resulting in higher mixing efficiency. Second, the mixing volume is larger. The secondary shaft 43 is hollow, with the secondary stirring blade 44 positioned on the outer side of the secondary shaft 43 and the spiral blade 42 positioned on the inner side. The effective range of the secondary stirring blade 44 extends from its horizontal outer edge to the outer wall of the secondary shaft 43. The spiral blade 42 operates approximately along the length of the secondary shaft 43. The combined volume of these components on the material is large, ensuring thorough stirring. Furthermore, this large-volume, interference-free stirring significantly improves the uniformity of the material mixing.

[0026] refer to Figure 3 , Figure 8 , Figure 10 and Figure 11 In one specific embodiment, the transmission assembly 3 includes a first main gear 31 fixed on the main shaft 22, a first secondary gear 36 fixed on the secondary shaft 43, and an internal gear ring 37 fixed on the inner wall of the vessel body 1. The first main gear 31 is located at the center of the internal gear ring 37, and the first main gear 31 meshes with the internal gear ring 37 through the first secondary gear 36. The first main gear 31 is sleeved and fixed to the outside of the main shaft 22. An extension frame is fixedly provided at the top of the secondary shaft 43, allowing material moving upward inside the secondary shaft 43 to be discharged through the gap in the extension frame. The first secondary gear 36 is fixedly provided at the top of the extension frame.

[0027] This embodiment uses a combination of a first main gear 31, a first secondary gear 36, and an internal gear ring 37, enabling the first secondary gear 36 to both rotate on its own axis and revolve around a central point. The first function is to achieve different stirring directions. (Reference) Figure 11When the first main gear 31 rotates clockwise, the first auxiliary gear 36 rotates counterclockwise. This means the main shaft 22 and the auxiliary shaft 43 rotate in opposite directions, effectively improving the mixing effect. Additionally, the auxiliary shaft 43 also revolves around the main shaft 22, further enhancing the mixing effect. Secondly, the mixing speeds differ. The first main gear 31 and the first auxiliary gear 36 have different diameters and rotate at different speeds, resulting in different mixing speeds for the materials, further improving the uniformity of the mixing.

[0028] refer to Figure 11 In one specific embodiment, the transmission assembly 3 includes a second main gear 32 fixed on the main shaft 22, a second auxiliary gear 35 fixed on the lifting shaft 41, and a support plate 38. Specifically, a sleeve is fixedly installed at the top of the center of the extension frame, the sleeve passes through the first auxiliary gear 36, and is fixed inside the first auxiliary gear 36. The lifting shaft 41 passes through the inside of the sleeve and is fixedly connected to the second auxiliary gear 35.

[0029] One end of the bearing plate 38 is rotatably sleeved on the main shaft 22, and the other end of the bearing plate 38 is rotatably sleeved on the outside of the sleeve of the auxiliary shaft 43. A transmission shaft 34 is also rotatably mounted on the bearing plate 38. A transmission gear 33 is fixed at the top of the transmission shaft 34. The two sides of the transmission gear 33 mesh with the second main gear 32 and the second auxiliary gear 35, respectively.

[0030] In this embodiment, a support plate 38 is set, which is rotatably connected to the main shaft 22 and the sleeve (i.e., the secondary shaft 43). In this way, the support plate 38 can move with the secondary shaft 43 as it revolves. A transmission gear 33 can be further set on the support plate 38 to transmit the power of the main shaft 22 to the second secondary gear 35, effectively completing the lifting of materials.

[0031] refer to Figure 3 and Figure 14 In one specific embodiment, the bottom diameter of the secondary shaft 43 is larger than the top diameter, causing the material inside the hollow interior to flow upward at an accelerated speed, thus enhancing the mixing effect. In this embodiment, the bottom diameter of the secondary shaft 43 is larger than the top diameter, resulting in accelerated upward flow of the material. Subsequently, the material is discharged from the top of the secondary shaft 43 at a higher speed. That is, the speed at which the material enters the secondary shaft 43 is different from the speed at which it exits, creating a speed difference. Therefore, the material's mixing is enhanced during the lifting process.

[0032] refer to Figure 3 In one specific embodiment, it also includes an airflow component 5, which is driven by the main stirring component 2 to discharge airflow from the top of the vessel body 1 and enter from the bottom of the vessel body 1, thereby realizing airflow circulation, increasing the disturbance of materials, and enhancing the mixing effect.

[0033] In this embodiment, airflow component 5 is used to achieve airflow circulation. The airflow flows from bottom to top, which can effectively agitate the materials. On the one hand, the airflow can stir the materials, avoid dead zones, and ensure thorough and uniform stirring; on the other hand, it prevents materials from bridging at the bottom of the vessel, thus improving the stirring effect.

[0034] refer to Figure 4 , Figure 6 and Figure 7 In one specific embodiment, the top of the vessel body 1 is provided with a top through hole 11, and the bottom of the vessel body 1 is provided with a bottom through hole 12.

[0035] The airflow assembly 5 includes blades 51, a pipe 52, a dustproof plate 53, and an exhaust column 54. The blades 51 are fixed to the main stirring assembly 2 and positioned above the transmission assembly 3, allowing the airflow to flow upwards into the top through-hole 11. The pipe 52 is fixed to the outside of the vessel body 1 and connects the top through-hole 11 and the bottom through-hole 12. The dustproof plate 53 is rotatably mounted on the main stirring assembly 2 and the auxiliary stirring assembly 4, and is positioned below the transmission assembly 3 to block dust generated by the material. The exhaust column 54 covers the bottom through-hole 12 to discharge gas.

[0036] In this embodiment, by setting up pipes 52, the airflow at the top of the vessel 1 can return to the bottom of the vessel 1 via the outside. This method not only achieves airflow circulation and avoids disturbing the material, but also increases the heat dissipation area of ​​the airflow through multiple dispersed pipes 52, cooling the high-temperature airflow before it enters the vessel 1. This prevents the high temperature inside the vessel 1 from damaging the effective components of the material. By setting up dustproof plates 53, dust generated during material mixing can be blocked, preventing dust from affecting the normal operation of the gears.

[0037] refer to Figure 8 and Figure 9 In one specific embodiment, the edge of the dustproof plate 53 is provided with a bent portion 531, and a curved channel is formed between the bent portion 531 and the inner wall of the vessel body 1 to prevent dust from entering. The exhaust column 54 includes a column body 541 and a conical cap 542 disposed at the top of the column body 541. The side wall of the column body 541 is provided with a side through hole for exhaust, and the lower edge of the conical cap 542 is lower than the side through hole.

[0038] refer to Figure 8In this embodiment, by setting a bending section 531, a curved channel is formed between the bending section 531, the side wall of the vessel body 1, and the internal gear ring 37. This effectively prevents dust from entering the transmission component 3, thus avoiding affecting the normal movement of the gears. Of course, depending on the actual situation, multiple bending sections 531 can be set to make the channel more complex. Filter structures such as filter screens or activated carbon particles can also be set in the curved channel to further remove dust. By setting a cone cap 542, it can prevent material from entering the bottom through hole 12 and disperse the airflow, allowing it to flow upwards from more angles, fully disturbing the material and making it more uniform.

[0039] refer to Figure 3 In one specific embodiment, a vibration component 6 is also included. The vibration component 6 is disposed on the bottom surface of the vessel body 1 and vibrates as the auxiliary stirring component 4 approaches or moves away to prevent material bridging.

[0040] This embodiment, by incorporating a vibration component 6, provides intermittent vibration. This serves two purposes: first, it prevents material bridging; second, it alters the upward trajectory of the airflow, causing it to rise disorderly and further increasing material disturbance, thus improving uniformity.

[0041] refer to Figures 12-14 In one specific embodiment, the vibration assembly 6 includes a housing 67 and a first magnet 68. The length of the housing 67 is arranged along the revolution direction of the auxiliary stirring assembly 4, i.e., a C-shape as shown in the figure. A swing arm 61 is provided inside the housing 67. The midpoint of the swing arm 61 is rotatably mounted on the inner wall of the housing 67 via a rotating shaft 62. Impact blocks 64 are respectively provided at both ends of the swing arm 61, and a second magnet 65 is provided inside each impact block 64. The housing 67, swing arm 61, rotating shaft 62, and impact blocks 64 are all made of non-ferromagnetic metal to avoid affecting the first magnet 68 and the second magnet 65.

[0042] The first magnet 68 is fixed to the bottom end of the auxiliary stirring assembly 4. Specifically, a bracket 45 is provided inside the bottom end of the auxiliary shaft 43. The first magnet 68 is provided on the bracket 45, and the volume and type of the first magnet 68 can be selected according to the actual situation.

[0043] The magnetic force between the first magnet 68 and the second magnet 65 causes the swing arm 61 to swing, which in turn causes the impact block 64 to strike the outer shell 67 and generate vibration.

[0044] This embodiment employs a first magnet 68 and a second magnet 65. As the first magnet 68 revolves around the secondary shaft 43, it attracts or repels the second magnet 65. Figure 12For example, the two magnets attract each other. When the secondary shaft 43 moves from right to left, it first attracts the second magnet 65 on the right to move upward, causing the right impact block 64 to impact the outer shell 67 and vibrate. As the secondary shaft 43 moves to the left, it then attracts the second magnet 65 on the left to move upward, causing the left impact block 64 to impact the outer shell 67 and vibrate. This allows the vibration assembly 6 to produce intermittent vibration, preventing material bridging.

[0045] refer to Figure 12 and Figure 13 In one specific embodiment, the inner top surface of the outer casing 67 is provided with an impact plate 66, which is correspondingly arranged with the impact block 64. The outer casing 67 is made of a non-metallic material.

[0046] In this embodiment, the outer casing 67 is made of a non-metallic material for two purposes. First, it avoids attenuating the magnetic force of the first magnet 68 and the second magnet 65, making it easier for them to interact. Second, the first magnet 68 is in motion and can easily generate eddy current heat on the outer casing 67, thus affecting the temperature of the material. The impact plate 66 is provided to increase durability and make the outer casing 67 more robust.

[0047] refer to Figure 12 and Figure 13 In one specific embodiment, a swing plate 63 is further provided inside the outer casing 67, and the swing plate 63 is disposed on both sides of the impact block 64. One end of the swing plate 63 is rotatably mounted on the inner wall of the outer casing 67 by a torsion spring or spring, and the other end is a free end. The elastic force of the torsion spring or spring on the swing plate 63 causes the free end of the swing plate 63 to tilt upward. Right-angled triangular protrusions are provided on both sides of the impact block 64. When the impact block 64 moves upward, the resistance is small, and when the impact block 64 moves downward, it can make the swing plate 63 vibrate.

[0048] In this embodiment, by setting up a swing plate 63, the swing plate 63 can be made to vibrate when the impact block 64 moves downward. Since the swing plate 63 is set on the outer shell 67, the swing plate 63 transmits the vibration to the outer shell 67, and the outer shell 67 further transmits the vibration to the material, preventing the material from bridging.

[0049] The above description discloses only preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention. Therefore, equivalent variations made in accordance with the claims of the present invention are still within the scope of the present invention.
