Description

Technical Field

[0001] This invention relates to the field of formulation equipment technology, and more specifically to a forced shear dispersion component based on a compound of oxadiazon and dicyananthraquinone. Background Technology

[0002] In the process of compounding azoxystrobin and dicyandioxanone, the two active ingredients have vastly different solubilities, requiring them to be processed into powder form through crushing or milling before being dissolved in an organic solvent to participate in the compounding in liquid form. However, due to the difference in density between the dispersed solid particles and water, they settle under gravity, resulting in a thinner upper layer (a transparent layer) and a thicker lower layer (particle aggregation) in the pre-mixed solvent.

[0003] To solve the above problems, referring to the resin processing raw material mixing tank disclosed in patent publication number CN114272816B, which is easy to clean, the mixing tank utilizes the interaction between the rotating gear ring and the rotating gear to make the stirring shaft and the mixing tank body move in opposite directions, thereby increasing the mixing effect of the raw materials. However, when applied to the compounding of oxadiazon and dicyananthraquinone, the difference in solubility between the two leads to stratification and agglomeration during stirring and mixing, resulting in poor compounding effect and affecting the quality of the final product. Therefore, this invention proposes a solution. Summary of the Invention

[0004] The technical problem to be solved by the present invention is that when oxamyl and dicyananthraquinone are compounded, due to the difference in solubility between oxamyl and dicyananthraquinone, stratification and agglomeration are likely to occur during the stirring and mixing process. Therefore, a forced shear dispersion component based on the compounding of oxamyl and dicyananthraquinone is provided to solve the above-mentioned technical problem.

[0005] The present invention provides the following device: a forced shear dispersion component based on a combination of oxadiazon and dicyananthraquinone, comprising a floating initial mixing component and a confluence final mixing component nested together, wherein the floating initial mixing component is floatingly disposed at the upper part of the inner side of the confluence final mixing component via rotation fulcrums on both sides. The floating primary mixing assembly includes a primary mixing tank with a tapered cylindrical shape that is wider at the top and narrower at the bottom, and a scraping assembly installed in the primary mixing chamber inside the primary mixing tank. The scraping assembly includes a grinding wheel and a side scraper that are attached to the bottom of the primary mixing tank. The bottom of the grinding wheel has a straight strip-shaped seepage hole and the outer periphery of the bottom is in line with the inner bottom of the primary mixing tank. The side scraper is tangentially in line with the inner wall of the primary mixing tank. The final mixing assembly includes a final mixing tank connected to the bottom of the primary mixing tank. A cover plate is installed at the upper end of the final mixing tank. When the primary mixing tank rotates around the pivot point, the outer edge of the upper end contacts the inner top of the cover plate. Both sides of the cover plate extend through the primary mixing tank into the interior of the final mixing tank and are equipped with drainage components for vertical convection of the mixture.

[0006] Furthermore, the drainage assembly includes a rotating rod that extends through the cover plate into the interior of the final mixing tank. The outside of the rotating rod is provided with a downward-pressing impeller and an upward-pushing impeller at intervals from top to bottom. The downward-pressing impeller and the upward-pushing impeller are arranged symmetrically in opposite directions, and the downward-pressing impeller and the upward-pushing impeller rotate in opposite directions.

[0007] Furthermore, a sedimentation tank is provided at the bottom of the final mixing tank, and a discharge port is provided in the middle of the sedimentation tank corresponding to the final mixing tank.

[0008] Furthermore, a continuously curved baffle is installed in the middle of the sedimentation tank corresponding to the final mixing tank. An arc-shaped groove is provided at the upper end of the baffle for guiding the rotation of the primary mixing tank, and the mixing areas on both sides of the baffle of the final mixing tank have the same volume.

[0009] Furthermore, the rotation fulcrum includes a rotating shaft fixedly installed on both sides of the primary mixing tank. One end of the rotating shaft is rotatably connected to the final mixing tank, and the other end of the rotating shaft is rotatably connected to the final mixing tank and extends to the outside to be connected to the swing motor. The primary mixing tank has a swing hole corresponding to the swing gap of the rotating rod.

[0010] Furthermore, the upper end of the grinding wheel has a conical cylindrical structure, and the grinding wheel is inclinedly mounted with a stirring blade through the conical cylindrical structure. The stirring blade is connected to the side scraper, and the inclination directions of the stirring blade and the side scraper are set at 180° to each other.

[0011] Furthermore, a rotary drive device is embedded in the inner bottom of the grinding wheel to drive the grinding wheel to rotate actively.

[0012] Furthermore, the bottom of the primary mixing tank is provided with uniformly distributed sinkholes that are connected to the mixing area of ​​the final mixing tank. A support column is installed in the middle of the sinkhole corresponding to the primary mixing tank, and the support column is connected to the output end of the rotary drive device.

[0013] Furthermore, a flexible conical tube is sealed to the upper end of the primary mixing tank corresponding to the primary mixing chamber. The upper end of the flexible conical tube is connected to the top of the inner cover plate, and a feed pipe is installed on the upper end of the cover plate corresponding to the flexible conical tube.

[0014] Compared with the prior art, the present invention has the following advantages and beneficial effects: 1. The mixing stage of the raw material liquid is divided into two parts by using a floating primary mixing component and a confluence final mixing component. The first dispersion stage utilizes the oscillating and rotating motion of the primary mixing tank and the internal swirling mixing motion to form the initial agitation and dispersion of the mixed liquid. Specifically, the cross-distribution of the stirring blades and side scrapers allows the liquid in the middle of the primary mixing tank to be separated from the outer periphery by the central dispersion action of the stirring blades. Then, the side scrapers complete the further turbulence and wall scraping of the separated liquid. During this process, the oscillating motor intermittently reverses forward and reverses, causing the primary mixing tank to oscillate, which, combined with the initial agitation and dispersion action, achieves the initial mixing of the mixed liquid.

[0015] 2. The second dispersion stage utilizes the drainage component in the confluence final mixing assembly to complete the secondary agitation and dispersion of the mixed liquid. Specifically, the mixed liquid entering the final mixing tank is subjected to the combined action of the downward pressure impeller and the upward push impeller. The inclined blades of the upward push impeller generate an upward axial force on the mixed liquid, thereby lifting the bottom mixed liquid upward, while the inclined blades of the downward pressure impeller generate a downward axial force on the mixed liquid, thereby pressing the upper mixed liquid downward, thus achieving efficient mixing.

[0018] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this invention are only used to explain this invention and are not intended to limit this invention.

[0019] Example 1: A forced shear dispersion component based on a combination of oxamyl and dicyananthraquinone, comprising a floating initial mixing component and a confluence final mixing component nested together, wherein the floating initial mixing component is floatingly positioned at the upper part of the inner side of the confluence final mixing component via rotation fulcrums on both sides. The floating primary mixing assembly includes a primary mixing tank 7 with a tapered cylindrical shape that is wider at the top and narrower at the bottom, and a scraping assembly installed in the primary mixing chamber 9 inside the primary mixing tank 7. The scraping assembly includes a grinding wheel 10 that fits against the bottom of the primary mixing tank 7 and a side scraper 16. The bottom of the grinding wheel 10 has a straight-shaped seepage hole 20 and the outer periphery of the bottom matches the inner bottom of the primary mixing tank 7. The side scraper 16 matches the inner wall of the primary mixing tank 7 tangentially. A rotary drive device is embedded in the inner bottom of the grinding wheel 10 to drive the grinding wheel 10 to rotate actively. The rotary drive device is preferably a rotary motor, which is not shown in the figure. The upper end of the grinding wheel 10 has a conical cylindrical structure. The grinding wheel 10 is inclinedly mounted with a stirring blade 15 through the conical cylindrical structure. The stirring blade 15 is connected to the side scraper 16, and the inclination directions of the stirring blade 15 and the side scraper 16 are set at 180° to each other.

[0020] Reference Figure 2 , Figure 4 - Figure 6 The mixing mechanism of the floating primary mixing component is as follows: In the initial state, the premixed liquid of oxadiazon and dicyandioxonine enters the primary mixing chamber 9 of the primary mixing tank 7. The rotary drive device embedded in the bottom of the grinding wheel 10 is activated, driving the grinding wheel 10 to rotate actively around the support column 21. Since the upper end of the grinding wheel 10 has a conical cylindrical structure, and the agitator 15 is installed obliquely through the conical cylindrical structure, when the agitator 15 rotates with the grinding wheel 10, its oblique surface generates a pushing force along the conical surface outward and upward on the liquid in the middle of the primary mixing chamber 9, causing the liquid in the middle to tilt and rise to the outer periphery. The side scraper 16, which is connected to the stirring blade 15 and is inclined at 180° to each other, performs tangential scraping and secondary turbulence on the liquid material that rises to the inner wall of the primary mixing tank 7, preventing the liquid material from adhering to the wall surface and breaking its circumferential laminar flow state; during this process, the outer periphery of the bottom of the grinding wheel 10 matches the inner bottom of the primary mixing tank 7, and the strip-shaped seepage hole 20 opened at the bottom allows the liquid material close to the bottom to periodically pass through the seepage hole 20 under the action of rotational shearing, forming a local high-pressure jet, which strengthens the hoisting and stripping of the bottom deposited particles; Meanwhile, the swing motor 3 drives the primary mixing tank 7 to swing intermittently in both directions around the pivot point via the rotating shaft. During the swing, the outer edge of the upper end of the primary mixing tank 7 intermittently contacts the inner top of the cover plate 2, generating periodic extrusion vibration. This vibration is transmitted through the tank wall to the liquid in the primary mixing chamber 9, further realizing the shearing and dispersion of the mixed liquid. Subsequently, the mixed liquid in the primary mixing chamber 9, after preliminary shearing and dispersion, seeps downward into the mixing area of ​​the final mixing tank 1 through the sinkholes 17 evenly distributed at the bottom of the primary mixing tank 7 under the combined action of the swing centrifugal force and gravity.

[0021] The final mixing assembly includes a final mixing tank 1 connected to the bottom of the primary mixing tank 7. A cover plate 2 is installed on the upper end of the final mixing tank 1. When the primary mixing tank 7 rotates around the pivot point, the outer edge of the upper end contacts the inner top of the cover plate 2. Both sides of the cover plate 2 extend through the primary mixing tank 7 into the interior of the final mixing tank 1 and are equipped with drainage components for vertical convection of the mixture.

[0022] The drainage assembly includes a rotating rod 6 that extends through the cover plate 2 into the interior of the final mixing tank 1. The outside of the rotating rod 6 is provided with a downward pressing impeller 11 and an upward pushing impeller 12 at intervals from top to bottom. The downward pressing impeller 11 and the upward pushing impeller 12 are arranged symmetrically in opposite directions, and the rotation directions of the downward pressing impeller 11 and the upward pushing impeller 12 are opposite. Reference Figure 3 , Figure 7 and Figure 8 The mixing mechanism of the final mixing assembly is as follows: the mixed liquid entering the final mixing tank 1 is vertically convectively dispersed under the action of the discharge assembly. When the upward impeller 12 rotates, its blades exert an upward axial thrust on the surrounding liquid, continuously lifting the liquid at the bottom of the final mixing tank 1. When the downward impeller 11 rotates, its blades exert a downward axial pressure on the surrounding liquid, continuously pressing the liquid in the upper part of the final mixing tank 1 downward. Two opposing axial flows converge and collide in the middle region of the final mixing tank 1, forming a strong turbulent shear layer. This forces particles of different densities and sizes to exchange and homogenize in the vertical direction. At the same time, the radial centrifugal force generated by the rotation of the downward impeller 11 and the upward impeller 12 throws the liquid towards the inner wall of the final mixing tank 1, further enhancing the mixing effect.

[0023] Additional explanation: The parameters of the two sets of drainage components are set as follows: the rotation speed of the rotating rod 6 on one side is intermittently alternating and set to be greater than that of the rotating rod 6 on the other side. The explanation for this is that during the vertical convection dispersion process, the mixed liquid in the two mixing sub-regions can present the effect of "overall unidirectional flow", that is, to achieve the overall "liquid exchange" effect, and further enhance the purpose of mixing and dispersion.

[0024] The bottom of the final mixing tank 1 is provided with a sedimentation tank 13, and the final mixing tank 1 is provided with a discharge port 14 in the middle of the sedimentation tank 13. The mixed liquid first completes the initial aggregation through the sedimentation tank 13, and after all the mixing is completed, it is discharged in a timed and quantitative manner through the discharge port 14 which is equipped with a pipeline valve.

[0025] Basic principle: The floating initial mixing component and the confluence final mixing component used in this invention divide the mixing stage of the raw material liquid into two parts. The first dispersion stage utilizes the swinging and rotating motion of the initial mixing tank 7 and the internal swirling mixing motion to form the initial agitation and dispersion of the mixed liquid. Specifically, the cross-distribution of the stirring blades 15 and the side scrapers 16 allows the liquid in the middle of the initial mixing tank 7 to be separated from the outer periphery by the central dispersion action of the stirring blades 15. Then, the side scrapers 16 complete the further turbulence and wall scraping of the separated liquid. During this process, the swing motor 3 intermittently reverses forward and reverses, causing the initial mixing tank 7 to swing, which, combined with the initial agitation and dispersion action, achieves the initial mixing of the mixed liquid. The second dispersion stage utilizes the drainage component in the confluence final mixing assembly to complete the secondary agitation and dispersion of the mixed liquid. Specifically, the mixed liquid entering the final mixing tank 1 is subjected to the combined action of the downward pressure impeller 11 and the upward push impeller 12. The inclined blades of the upward push impeller 12 generate an upward axial force on the mixed liquid, thereby lifting the bottom mixed liquid upward. Meanwhile, the inclined blades of the downward pressure impeller generate a downward axial force on the mixed liquid, thereby pressing the upper mixed liquid downward, thus achieving efficient mixing.

[0026] Example 2: Refer to Figure 3 and Figure 7 This embodiment is based on the first embodiment and further optimizes the structure of the final mixing component. It includes a continuously curved baffle 18 installed in the middle of the sedimentation tank 13 corresponding to the final mixing tank 1, preferably a flat "S" shape. The upper end of the baffle 18 is provided with an arc-shaped groove for the rotation guidance of the primary mixing tank 7, and the mixing area on both sides of the baffle 18 corresponding to the final mixing tank 1 has the same volume. It should be noted that the purpose of the baffle 18 is to divide the inner cavity of the final mixing tank 1 into two mixing sub-regions of equal volume. Each sub-region is equipped with a downward impeller 11 and an upward impeller 12 of the drainage assembly. When the mixed liquid moves under the above-mentioned vertical convection, its axial flow is blocked and guided by the baffle 18. The continuous curved shape of the baffle 18 forces the liquid to generate a wall adhesion effect and flow direction deflection when it flows over its surface, transforming the original single axial up-and-down convection into a three-dimensional composite flow that simultaneously includes axial, radial and circumferential components. When the liquid impacts the curved surface of the baffle 18, it generates a large number of vortices of different sizes. These vortices move with the mainstream and superimpose with each other, thereby increasing the contact area and collision frequency of the components inside the mixed liquid.

[0027] The pivot point includes a pivot shaft fixedly installed on both sides of the primary mixing tank 7. One end of the pivot shaft is rotatably connected to the final mixing tank 1, and the other end of the pivot shaft is rotatably connected to the final mixing tank 1 and extends to the outside to be connected to the swing motor 3. The primary mixing tank 7 is provided with a swing hole 19 corresponding to the swing gap of the rotating rod 6. The radial dimension of the swing hole 19 is larger than the outer diameter of the rotating rod 6, so as to provide sufficient clearance space for the primary mixing tank 7 to swing around the pivot point and ensure that the primary mixing tank 7 and the rotating rod 6 do not have mechanical interference during the swing process. Reference Figure 2 - Figure 4 As shown, the purpose of setting the pivot point is to: output intermittent forward and reverse torque through the swing motor 3, and transmit it to the primary mixing tank 7 through the rotating shaft, so that it swings back and forth around the axis of the rotating shaft at the upper part of the inner side of the final mixing tank 1. The swing angle range is limited by the contact limit between the outer edge of the upper end of the primary mixing tank 7 and the top of the inner cover plate 2. The upper end of the primary mixing tank 7 is sealed with a flexible cone tube 8 corresponding to the primary mixing chamber 9. The upper end of the flexible cone tube 8 is connected to the top of the cover plate 2. The upper end of the cover plate 2 is equipped with a feed pipe 4 corresponding to the flexible cone tube 8. The flexible cone tube 8, made of flexible material, plays a role in sealing and connecting, ensuring that it can adapt to the swing deformation of the primary mixing tank 7. The bottom of the primary mixing tank 7 is provided with uniformly distributed sinkholes 17 that are connected to the mixing area of ​​the final mixing tank 1. A support column 21 is installed in the middle of the sinkholes 17 in the primary mixing tank 7. The support column 21 is connected to the output end of the rotary drive device. During the rotation of the grinding wheel 10, its bottom is connected to the support column 21, and the support column 21 provides a permeation gap between the bottom of the grinding wheel 10 and the bottom of the primary mixing tank 7, ensuring effective connection between the primary and secondary mixing.

[0028] Example 3: The difference from Example 1 is that the grinding wheel 10 abuts against the support column 21, and the seepage hole 20 is a spiral strip extending through the grinding wheel 10. In a static state, a spiral strip-shaped channel (seepage hole 20) exists between the outer side of the grinding wheel 10 and the inner wall of the primary mixing tank 7. At this time, the grinding wheel 10 does not have an active rotation function; it rotates due to the swirling effect of the spiral strip-shaped seepage hole 20 as the mixed liquid is injected. During this process, the mixing mechanism of the floating primary mixing component has the same effect as in Example 1, achieving the initial mixing effect of the mixed liquid.

[0029] Example 4: Refer to Figure 1 - Figure 7 As shown, this embodiment combines the technical content of Embodiment 1 and Embodiment 2 to form the following mixing method: Step 1: First, the oxadiazon technical powder and dicyananthraquinone technical powder are mixed with an organic solvent in a predetermined ratio in an external premixing tank to form a premixed liquid. Step 2: The premixed liquid is continuously fed into the primary mixing chamber 9 of the primary mixing tank 7 through the feed pipe 4 and the flexible cone pipe 8. The rotary drive device is started to drive the grinding wheel 10 to rotate at the first speed. The stirring blade 15 applies an outward and upward inclined pushing force to the liquid in the middle of the primary mixing chamber 9. The side scraper 16 performs tangential scraping and stirring of the liquid near the inner wall of the primary mixing tank 7. At the same time, the oscillating motor 3 is started, and the primary mixing tank 7 is driven to oscillate back and forth intermittently around the rotation fulcrum at the first oscillation frequency through the rotating shaft. The outer edge of the upper end of the primary mixing tank 7 intermittently contacts the inner top of the cover plate 2 to generate vibration, which applies periodic disturbance to the liquid in the primary mixing chamber 9 and continues to carry out the first dispersion stage. Step 3: After the first dispersion stage is completed, the mixed liquid is discharged through the sinkholes 17 evenly distributed at the bottom of the primary mixing tank 7 and enters the mixing area of ​​the final mixing tank 1 under the combined action of centrifugal force and gravity. Step 4: Start the drainage assembly. The rotating rod 6 drives the downward impeller 11 and the upward impeller 12 to rotate synchronously in opposite directions. The downward impeller 11 applies downward axial pressure to the liquid in the upper part of the final mixing tank 1, and the upward impeller 12 applies upward axial thrust to the liquid in the lower part of the final mixing tank 1. The two opposing axial flows converge in the middle of the final mixing tank 1 to generate turbulent shear. At the same time, they are guided by the continuous curved baffle 18 to generate three-dimensional composite flow, which performs the second dispersion stage of the mixed liquid. Step 5: After the second dispersion stage is completed, the mixed liquid is discharged from the outlet 14 to complete the collection.

[0030] In summary, the floating initial mixing component and the confluence final mixing component used in this invention divide the mixing stage of the raw material liquid into two parts. In the initial mixing stage: the initial mixing tank 7 utilizes its own oscillating and rotating motion and internal swirling mixing motion to achieve initial agitation and dispersion of the mixed liquid. Specifically, the mixing blades 15 and side scrapers 16 are arranged in a cross pattern, allowing the liquid in the middle of the initial mixing tank 7 to separate upwards and outwards under the central dispersion effect of the mixing blades 15. Then, the side scrapers 16 complete the further turbulence and wall scraping of the separated liquid. During this process, the oscillating motor 3 intermittently reverses direction, causing the initial mixing tank 7 to oscillate and generate periodic squeezing vibrations, which, combined with the initial agitation and dispersion motion, achieve the initial mixing of the mixed liquid. In the final mixing stage: the drainage component in the confluence final mixing assembly completes the secondary agitation and dispersion of the mixed liquid. Specifically, the mixed liquid entering the final mixing tank 1 is subjected to the combined action of the downward pressure impeller 11 and the upward push impeller 12. The inclined surface of the blades of the upward push impeller 12 generates an upward axial force on the mixed liquid, thereby lifting the bottom mixed liquid. The inclined surface of the blades of the downward pressure impeller generates a downward axial force on the mixed liquid, thereby pressing the upper mixed liquid down. Combined with the radial centrifugal force generated by the rotation of the downward pressure impeller 11 and the upward push impeller 12, a three-dimensional composite mixing effect of the liquid is achieved. This method utilizes the synergistic effect of the oscillating dispersion shearing mechanism of the floating initial mixing component and the vertical convection impact dispersion mechanism of the confluence final mixing component to address the stratification and agglomeration problems caused by the solubility difference in the compounding process of oxamyl and dicyananthraquinone. It achieves a multi-dimensional forced shear dispersion effect of shearing and three-dimensional composite turbulent mixing, thereby improving the dispersion efficiency in the compounding process.
