Description

Technical Field

[0001] This invention relates to the field of pesticide preparation technology, and in particular to a seed treatment suspension containing difenoconazole and its preparation apparatus. Background Technology

[0002] Seed treatment suspensions are liquid formulations that use water as the dispersion medium and refine the active ingredients and adjuvants through wet grinding. Due to their safety for seeds, good film-forming properties, long-lasting efficacy, and environmental friendliness, they have become one of the important pesticide formulations for the control of modern seed-borne and soil-borne diseases. Difenoconazole, as a highly efficient and broad-spectrum triazole fungicide, is widely used in the field of seed treatment and has excellent control effects on a variety of fungal diseases. In the preparation process of seed treatment suspensions, in order to obtain a highly dispersed, uniform, and stable suspension system of active ingredients such as difenoconazole and various adjuvants in water, it is usually necessary to use high-shear emulsification equipment to subject them to strong shearing, impact, and turbulence, thereby achieving rapid mixing, refinement, and homogenization of materials.

[0003] Existing high-shear emulsification preparation devices achieve material shearing and emulsification through the high-speed rotation of the rotor in the emulsification head and the precise coordination with the stator. However, the shearing coverage area is relatively small. Therefore, it is necessary to use an internal stirring mechanism in the processing tank to drive the material inside the tank to the emulsification head to achieve the best shearing and mixing effect. However, the stirring mechanism cannot ensure that all the material inside the tank flows to the optimal coverage area of ​​the emulsification head, resulting in differences in the shearing effect of the material inside the tank and reducing the overall shearing and emulsification effect of the material. Summary of the Invention

[0004] This invention discloses a preparation apparatus aimed at solving the technical problem that in existing high-shear emulsification devices, the shear coverage area of ​​the emulsification head is small, and a stirring mechanism is needed to transport the material in the tank to the emulsification head to achieve the best effect. However, stirring cannot ensure that all the material enters the optimal coverage area of ​​the emulsification head, resulting in inconsistent shear effects in different parts of the material and reducing the overall emulsification uniformity.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A seed treatment suspension of difenoconazole comprises the following components in weight percentage: 2%–8% difenoconazole, 2%–10% wetting and dispersing agent, 1%–6% film-forming agent, 0.2%–2% thickener, 2%–5% antifreeze agent, 0.5%–3% colorant, 0.2%–0.5% defoamer, 0.2%–0.5% preservative, with the balance being water; and the seed treatment suspension has a suspension rate ≥90% and a particle size D90 ≤5μm.

[0007] The wetting and dispersing agent is a mixture of fatty alcohol polyoxyethylene ether and sodium dodecylbenzene sulfonate, wherein the weight ratio of fatty alcohol polyoxyethylene ether to sodium dodecylbenzene sulfonate is 1:0.5 to 1:2; the film-forming agent is a mixture of polyvinyl alcohol and chitosan, wherein the weight ratio of polyvinyl alcohol to chitosan is 1:0.3 to 1:1; the thickener is xanthan gum; and the antifreeze agent is ethylene glycol.

[0008] The colorant is basic rose extract or carmine, the defoamer is an organosilicon defoamer, and the preservative is sodium benzoate.

[0009] It should be noted that the chitosan is pre-dissolved in a dilute acid aqueous solution, such as an acetic acid aqueous solution with a mass fraction of 0.5% to 2%, before use, and then mixed with other components; or, a pH adjuster is added during the preparation of the seed treatment suspension to make the pH of the system 4.0 to 6.0, so as to ensure that the chitosan is fully dissolved and can play a film-forming role.

The material is separated by the lifting sleeve frame and the separating ring frame, resulting in a bottom-up flow of material, thereby ensuring that the material circulates into the central frame and improves the material shearing effect.

[0057] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0058] Example 1:

[0059] A seed treatment suspension of difenoconazole is composed of the following components in weight percentage: 2% difenoconazole, 2% wetting and dispersing agent, 1% film-forming agent, 0.2% thickener, 2% antifreeze agent, 0.5% colorant, 0.2% defoamer, 0.2% preservative, and the balance being water; and the seed treatment suspension has a suspension rate ≥90% and a particle size D90 ≤5μm.

[0060] Specifically, the wetting and dispersing agent is a mixture of fatty alcohol polyoxyethylene ether and sodium dodecylbenzene sulfonate, wherein the weight ratio of fatty alcohol polyoxyethylene ether to sodium dodecylbenzene sulfonate is 1:0.5; the film-forming agent is a mixture of polyvinyl alcohol and chitosan, wherein the weight ratio of polyvinyl alcohol to chitosan is 1:0.3; the thickener is xanthan gum; and the antifreeze agent is ethylene glycol.

[0061] It should be noted that the colorant is alkaline rose extract, the defoamer is an organosilicone defoamer, and the preservative is sodium benzoate.

[0062] Reference Figures 1-10 A preparation apparatus, used in the above-described seed treatment suspension containing difenoconazole, comprising:

[0063] Processing tank 1;

[0064] The quick docking mechanism 5 is set in the reserved hole opened on the top of the processing tank 1. The quick docking mechanism 5 includes a docking ring frame 501, and the docking ring frame 501 is fixedly connected to the reserved hole.

[0065] Two mounting rods 10 are fixedly connected to the inner side wall of the treatment tank 1 near the bottom.

[0066] A central shearing mechanism 9 is disposed on two mounting inner rods 10. The central shearing mechanism 9 includes a central frame 901, and the central frame 901 is fixedly connected to the opposite side of the two mounting inner rods 10.

[0067] The feeding nozzle 2 is fixedly connected to the feeding hole on the processing tank 1, and the feeding nozzle 2 is connected to the flip cover 3 by a hinge;

[0068] Base 6 is located at the bottom of processing tank 1;

[0069] The discharge pipe 7 is fixedly connected to the discharge hole at the bottom of the processing tank 1, and the outer wall of the discharge pipe 7 is connected to the pipe valve 8 through a flange.

[0070] In specific application scenarios, during the shearing and emulsification process, the central frame 901 separates the optimal shearing area from other spaces inside the processing tank 1. After the emulsifying head 14 efficiently shears the interior of the central frame 901, the adjusting lifting cylinder 904 drives the drain pressure plate 902 to press down. When the adapter ring plate 903 separates from the adapter sealing hole, the material inside the central frame 901 is squeezed out. When the drain pressure plate 902 moves below the emulsifying head 14, the hydraulic cylinder 915 drives the sealing plate 918 to seal the central hole of the drain pressure plate 902. The drain pressure plate 902 then... Most of the material in frame 901 is discharged. When the drainage pressure plate 902 contacts the pressing ring 20, the hydraulic cylinder 913 drives the limiting cutting plate 914 to separate from the feeding gate 905. The feeding gate 905 deflects under the gravity of the material above, and the material above gradually fills the drainage pressure plate 902 and the sealing plate 918, completing one replacement of the material shearing in the central frame 901. The material is separated by the lifting sleeve frame 12 and the separating ring frame 13, so that the material presents a bottom-up flow, thereby making the material circulate into the central frame 901 and improving the material shearing effect.

The outer side wall of the hanger rod 909 has a shaft groove. A sleeve 910 is sleeved on the shaft groove. The outer side wall of the sleeve 910 has auxiliary rotating blades 908 distributed in a ring.

[0076] Two mounting blocks 916 are symmetrically distributed in the annular groove opened on the top of the drainage pressure plate 902. Hydraulic cylinders 915 are fixedly connected to the opposite side of the two mounting blocks 916. Sealing plates 918 are fixedly connected to the output ends of the two hydraulic cylinders 915. The two closed sealing plates 918 match the center hole of the drainage pressure plate 902.

[0077] Reference Figures 4-6 In a preferred embodiment, the central shearing mechanism 9 further includes:

[0078] Two feed doors 905 are connected by hinges to the door openings at the top of the center frame 901;

[0079] Two sealing sleeves 911 are set on the top inner wall of the center frame 901 near the feed door 905. The feed door 905 is located inside the sealing sleeve 911 and is fixedly connected to the bottom of the sealing sleeve 912 at equal distances. The ends of multiple return springs 912 are fixedly connected to the same integrated rod 917. The integrated rod 917 is fixedly connected to the top inner wall of the center frame 901 inside the sealing sleeve 911.

[0080] Limiting block 906 is fixedly connected to the center frame 901 above the feed gate 905.

[0081] Two hydraulic cylinders 913 are fixedly connected to the inner wall of the center frame 901 away from the sealing sleeve 911. The output ends of the two hydraulic cylinders 913 are fixedly connected to a limiting cutting plate 914. The limiting cutting plate 914 is in contact with the bottom of the feed gate 905. The upper surface of the limiting cutting plate 914 is a slope.

[0082] Reference Figure 2 , Figure 3 and Figure 6In a preferred embodiment, the top of the drainage pressure plate 902 has two sliding holes, and the interior of each sliding hole is slidably connected to a sliding outer cylinder 18. The bottom inner wall of the center frame 901 located below the two sliding outer cylinders 18 is fixedly connected to a fixed sliding rod 19. The sliding outer cylinder 18 is slidably connected to the outside of the fixed sliding rod 19. The outer wall of the sliding outer cylinder 18 near the bottom is fixedly connected to a pressing ring 20. The top of the fixed sliding rod 19 has a groove extending to the bottom. The top inner wall of the sliding outer cylinder 18 is fixedly connected to a supporting spring rod 21. The bottom of the supporting spring rod 21 is fixedly connected to the bottom of the groove. The top of the center frame 901 at the edge is fixedly connected to a separating ring frame 13. The outer wall of the separating ring frame 13 is fixedly connected to an outer connecting ring 11. The top of the outer connecting ring 11 is fixedly connected to two adjusting cylinders. The output ends of the two adjusting cylinders are fixedly connected to adjusting ring rods 16. A lifting sleeve 12 is fixedly connected to the adjusting ring rod 16. The lifting sleeve 12 is sleeved on the separating ring frame 13.

[0083] Specifically, before material shearing and emulsification, the height of the lifting frame 12 is adjusted according to the total amount of material added. The adjusting cylinder is activated to drive the lifting frame 12 to slide on the separating ring frame 13. This method allows the material below the center frame 901 to push the material above when the material is discharged downwards, so that the material at the top crosses the top of the lifting frame 12 and enters the area above the center frame 901, realizing the position change of the material.

[0084] It should be noted that after the drainage pressure plate 902 contacts the pressing ring 20, the drainage pressure plate 902 drives the pressing ring 20 to press down synchronously, and the support spring rod 21 is gradually compressed. When the drainage pressure plate 902 moves to the bottom, during the reset process, the support spring rod 21 drives the sliding outer cylinder 18 to reset. The sliding outer cylinder 18 pushes the upper feed gate 905 downward. The support spring rod 21 and the reset spring 912 cooperate to realize the effective reset of the feed gate 905.

[0085] Reference Figure 2 , Figure 7 , Figure 8 , Figure 9 and Figure 10 In a preferred embodiment, the quick docking mechanism 5 further includes:

[0086] Multiple fine-tuning rails 502 are set in the mounting holes opened at the top of the docking ring frame 501. Each fine-tuning rail 502 has a fine-tuning slider 507 slidably connected inside. The top of the fine-tuning slider 507 is fixedly connected to the upper lifting frame 504. The top of the upper lifting frame 504 is fixedly connected to the positioning cylinder 503.

[0088] The lower pressure ring 513 has two connecting sliders 511 fixedly connected to its outer side wall, and two connecting grooves 508 are opened on the inner side wall of the mating ring frame 501. The connecting sliders 511 are slidably connected in the adjacent connecting grooves 508.

[0089] Multiple shock-absorbing spring rods 509 are fixedly connected to the bottom of the lower pressure ring 513;

[0090] The support ring 512 is fixedly connected to the inner wall of the docking ring frame 501 located below the pressure ring 513. The top of the support ring 512 has an annular groove, and the bottom inner wall of the annular groove is provided with pressure sensors 514 arranged in a ring.

[0091] Specifically, during the installation of the emulsifying head 14, the fixed plate 23 is aligned with the docking ring frame 501 and pressed in. After the fixed plate 23 contacts the lower pressure ring 513, the fine-tuning cylinder 505 is adjusted to move the fine-tuning slider 507, causing the positioning plate 506 to move above the fixed plate 23. The positioning cylinder 503 is then activated to drive the positioning plate 506 to press down on the fixed plate 23. As the fixed plate 23 descends, the shock-absorbing spring rod 509 is continuously compressed. The compressed shock-absorbing spring rod 509 weakens the vibration during the operation of the drive motor 4, reducing the interference caused by vibration. At the same time, the pressure sensor 514 monitors the pressure above in real time. After the positioning cylinder 503 drives the positioning plate 506 to press the lower pressure plate to the designated position, the operation stops. In the current state, the fixed plate 23 is stably clamped and will not be damaged due to excessive compression.

[0092] It should be noted that when different emulsifying heads 14 need to be replaced, the quick-connect mechanism 5 can be used to quickly replace the emulsifying head 14, which is convenient and efficient.

[0095] Multiple fine-tuning cylinders 505 are fixedly connected to the top of each fine-tuning rail 502, and the output end of the fine-tuning cylinder 505 is fixedly connected to one side of the adjacent fine-tuning slider 507.

[0100] Multiple support rods 15 are fixedly connected to the bottom of the fixed plate 23;

[0101] The emulsifying head 14 is fixedly connected to the bottom of multiple support rods 15. The emulsifying head 14 consists of a rotor and a stator. The rotor is fixedly connected to the bottom end of the central shaft 17, and the rotor and stator are precisely matched.

[0102] Method for preparing the above-described suspending agent using the preparation apparatus

[0103] Weigh each component according to the above weight percentages, add water to treatment tank 1, and then add wetting and dispersing agent, pre-dissolved film-forming agent (a mixture of polyvinyl alcohol and chitosan), antifreeze, colorant, defoamer, and preservative in sequence. After initial mixing, add difenoconazole technical grade, cover with flip-top 3, start drive motor 4, and emulsify the material through emulsifying head 14 fixed by quick docking mechanism 5. At the same time, the central shearing mechanism 9 operates as follows: lifting cylinder 904 drives drainage pressure plate 902 to move up and down periodically, and with the opening and closing of feed door 905, the material in treatment tank 1 continuously circulates into central frame 901 to receive full shearing from emulsifying head 14. Shearing treatment is carried out for 45 minutes, and samples are taken for testing until the suspension rate is ≥90% and the particle size D90≤5μm. Finally, pipe valve 8 is opened, and the finished suspension is discharged through discharge pipe 7.

[0104] Working principle of the device

[0105] Working Principle: During use, before material shearing and emulsification, the height of the lifting frame 12 is adjusted according to the total amount of material added. The adjusting cylinder is activated, causing the lifting frame 12 to slide on the separating ring frame 13, thus adjusting the separation height. Then, material is added into the processing tank 1 through the feeding nozzle 2. After material addition, the drive motor 4 is activated, driving the central shaft 17 to rotate, thereby causing the rotor to rotate at high speed. The rotor and stator cooperate to begin material shearing and emulsification. During the shearing and emulsification process, the central frame 901 separates the optimal shearing area from other spaces inside the processing tank 1. After the emulsifying head 14 efficiently shears the interior of the central frame 901, the adjusting lifting cylinder 904 drives the drain pressure plate 902 to press down. When the adapter ring plate 903 separates from the adapter sealing hole, the interior of the central frame 901... The material in the middle is squeezed out. When the drain plate 902 moves to below the emulsifying head 14, the hydraulic cylinder 915 drives the sealing plate 918 to seal the center hole of the drain plate 902. The drain plate 902 then discharges most of the material in the center frame 901. When the drain plate 902 contacts the pressing ring 20, the hydraulic cylinder 913 drives the limiting cutting plate 914 to separate from the feed gate 905. The feed gate 905 deflects under the gravity of the material above, and the material above gradually fills the drain plate 902 and the sealing plate 918, completing one replacement of the material shearing in the center frame 901. The material is separated by the lifting sleeve frame 12 and the separating ring frame 13, so that the material presents a bottom-up flow, so that the material circulates into the center frame 901. After the material circulates for a period of time, the shearing and emulsification operation ends.
