Description

Technical Field

[0001] This utility model relates to the field of pesticide production equipment technology, specifically a high-speed homogenization mixing device for rice paddy herbicides. Background Technology

[0002] In the production and preparation of herbicides for paddy fields, it is usually necessary to fully mix and homogenize various active ingredients, solvents, emulsifiers and various adjuvants to ensure that the active ingredients in the final product are evenly distributed and the efficacy is stable and reliable. As a key link in the production of herbicides, the performance of the equipment used in the mixing process directly affects the quality of the product and the smooth progress of subsequent processing.

[0003] Currently, most conventional mixing equipment used in pesticide production is a single-shaft stirring structure equipped with a single type of agitator. When dealing with complex systems such as herbicides, which typically contain solid suspended particles, high-viscosity liquids, and multiple components with large density differences, this type of equipment often fails to achieve ideal mixing results. The flow field generated by the single stirring method is relatively fixed, which easily forms a mixing dead zone in the tank. This results in the material deposited at the bottom of the tank not being able to effectively participate in the circulation, leading to unstable product quality between batches. In addition, existing equipment generally lacks efficient circulation homogenization methods. For systems that require high dispersion and emulsification, it is difficult to achieve the required micro-mixing uniformity in a short time by simply relying on mechanical stirring, which not only prolongs the production cycle but also increases energy consumption. Utility Model Content

[0004] The purpose of this invention is to provide a high-speed homogenizing and mixing device for rice paddy herbicides, which has the advantages of high mixing efficiency, good homogenization effect, and no mixing dead zones, thus solving the problems in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A high-speed homogenizing and mixing device for rice paddy herbicides includes a support plate, a mixing tank fixed to the upper part of the support plate, a top plate fixed to the upper part of the mixing tank, support legs fixed to the four corner edges of the lower part of the support plate, a first drive mechanism disposed on the upper part of the top plate, a first rotating column rotatably mounted on the top plate via bearings, a second drive mechanism fixed to the lower part of the support plate, a second rotating column rotatably mounted on the lower part of the support plate via bearings, and two liquid extraction mechanisms disposed on the outer peripheral wall of the mixing tank.

[0007] The upper end of the second rotating column passes through the bottom of the mixing tank and is rotatably supported at the bottom of the mixing tank by a sealed bearing, and the upper end of the second rotating column extends into the interior of the mixing tank; a stirring mechanism is provided on the outer peripheral wall of the second rotating column, and a second toothed ring is fixedly connected to the lower part of the outer peripheral wall of the second rotating column; a second driving mechanism is used to drive the second toothed ring.

[0008] The mixing tank is equipped with a liquid outlet mechanism at the lower end and a liquid inlet mechanism at the upper end.

[0009] A first toothed ring is fixedly connected to the upper part of the outer peripheral wall of the first rotating column. A first driving mechanism is used to drive the first toothed ring. The lower end of the first rotating column passes through the mixing tank and extends into the mixing tank. Multiple stirring blocks are fixedly connected to the lower part of the outer peripheral wall of the first rotating column.

[0010] Preferably, the first drive mechanism includes a first fixed base fixed to the upper end of the top plate, a first motor fixed to the first fixed base, and a first gear fixed to the lower end of the output shaft of the first motor, wherein the first gear and the first gear ring mesh with each other.

[0011] It is worth noting that by using the meshing transmission method of the first motor, the first gear, and the first gear ring to drive the first rotating column to rotate, a stable and strong rotational power can be provided to the stirring blocks. The external gear drive structure not only avoids direct contact between the motor and corrosive materials or gases in the mixing tank, effectively extending the service life of the drive components, but also facilitates daily maintenance and repair. The meshing of the first gear and the first gear ring can ensure the stability of the first rotating column when rotating at high speed, thereby driving multiple stirring blocks in the lower part to form an efficient shear flow field in the upper space of the mixing tank, realizing the initial crushing and dispersion of large particles or high-density components, creating favorable conditions for subsequent deep homogenization and mixing.

[0012] Preferably, the stirring mechanism includes a first fixed disk fixed to the upper part of the outer peripheral wall of the second rotating column and a plurality of fan blades fixed to the upper end of the first fixed disk, the plurality of fan blades being circumferentially distributed.

[0013] It is worth noting that the multiple fan blades distributed in a circular pattern on the upper part of the first fixed plate constitute the core radial flow stirring unit of the equipment. When the second rotating column is driven to rotate, these fan blades will generate a strong radial thrust, forcing the material to move at high speed from the center to the tank wall. After impacting the tank wall, it forms an up-and-down circulating tumbling effect, which can quickly eliminate the material concentration gradient in the upper part of the mixing tank and prevent the occurrence of stratification. It is particularly suitable for scenarios that require rapid mixing of multiple liquid raw materials and additives.

[0014] Preferably, the stirring mechanism further includes a second fixed plate fixed to the middle of the outer peripheral wall of the second rotating column, a first groove extending through the upper end of the second fixed plate, a plurality of columns fixed to the upper end of the first fixed plate, a third fixed plate fixed to the upper end of the plurality of columns, and a second groove extending through the upper end of the third fixed plate.

[0015] It is worth noting that the second and third fixed discs are connected by multiple columns to form a stable cage-like structure. Furthermore, the first and second grooves on the disc surfaces constitute a unique labyrinthine channel. When materials are forced to pass through these grooves during mixing, the sudden change in the flow cross-section generates strong turbulence, shearing, and compression, thereby achieving micro-refinement and homogenization of the materials. This structure is equivalent to integrating a multi-stage dynamic mixing unit within the tank, greatly increasing the probability of collision and dispersion of high-viscosity or herbicide materials containing suspended particles during flow, effectively solving the problem of uneven micro-mixing that easily occurs in conventional mixing equipment.

[0016] Preferably, the stirring mechanism further includes a scraper fixed to the lower part of the outer peripheral wall of the second rotating column, with the lower end of the scraper in contact with the bottom surface of the inner wall of the mixing tank.

[0017] It is worth noting that the scraper is directly attached to the bottom of the inner wall of the mixing tank and rotates synchronously with the second rotating column. This structure has a dual key function: First, it can continuously scrape off undissolved raw materials, fillers, or high-density particles deposited at the bottom of the tank, forcing them to re-participate in the circulation and mixing, completely eliminating the mixing dead zone and preventing formulation inaccuracies caused by sedimentation. Second, in the subsequent discharge process, the rotating scraper can guide the material to converge at the liquid outlet, achieving near-zero residue discharge, which not only improves the raw material utilization rate but also greatly simplifies the cleaning process between batches and avoids cross-contamination between different batches of products.

[0018] Preferably, the liquid discharge mechanism includes a liquid discharge pipe that is fixedly connected to the lower end of the mixing tank and a sixth valve body disposed on the liquid discharge pipe. The lower end of the liquid discharge pipe passes through the lower end of the support plate and extends to the bottom of the support plate. The liquid inlet mechanism includes two liquid inlet pipes that are fixedly connected to the upper end of the mixing tank and a fifth valve body disposed on the liquid inlet pipe. The upper end of the liquid inlet pipe passes through the upper end of the top plate and extends to the top of the top plate.

[0019] It is worth noting that placing the inlet pipe at the top of the mixing tank and extending it above the top plate facilitates connection to upstream metering or feeding equipment, enabling gravity or pressure feeding and simplifying the process. Meanwhile, the outlet pipe extends from the bottom of the tank to below the support plate, making full use of the liquid level difference or cooperating with downstream filling equipment to achieve smooth and rapid discharge. The design of the fifth and sixth valve bodies allows operators to precisely control the timing and flow rate of raw material injection, as well as control the output of the finished product after mixing, enhancing the flexibility and controllability of the process operation and ensuring that the entire batch production process is carried out in an orderly and accurate manner.

[0020] Preferably, the second drive mechanism includes a second fixed base fixed to the lower end of the support plate, a second motor fixed to the second fixed base, and a second gear fixed to the upper end of the output shaft of the second motor, wherein the second gear and the second gear ring mesh with each other.

[0021] It is worth noting that the second drive mechanism is installed at the lower end of the support plate, and the second rotating column is driven by the meshing of the second gear and the second gear ring. This layout utilizes the space under the support plate, making the overall structure of the equipment more compact. The design of the first drive mechanism and the independent drive mechanism allows the first and second rotating columns to run at different speeds and directions. It can flexibly adjust the mixing process parameters according to the characteristics of different materials in the herbicide formulation (such as viscosity and solubility). The design of two independent drive sources at the top and bottom also means that even if one drive system is under maintenance, the other mixing system can still maintain basic mixing functions, improving the reliability of equipment operation.

[0022] Preferably, the liquid extraction mechanism includes a first fixing block fixed to the outer peripheral wall of the mixing tank, a first fixing pipe disposed on the inner wall of the first fixing block, a first valve body disposed on the first fixing pipe, a second fixing block fixed to the outer peripheral wall of the mixing tank, a second fixing pipe fixed to the inner wall of the second fixing block, a second valve body disposed on the second fixing pipe, a pump body disposed outside the support plate, a liquid extraction pipe disposed at the liquid extraction end of the pump body, and a third valve body disposed on the liquid extraction pipe. The liquid extraction end of the liquid extraction pipe is connected to the liquid outlet end of the second fixing pipe. The liquid outlet end of the pump body is connected to the liquid inlet end of the first fixing pipe through a pipe. The liquid outlet end of the first fixing pipe passes through the outer peripheral wall of the mixing tank and extends to the inner wall of the mixing tank.

[0023] It is worth noting that the material at the bottom of the mixing tank is drawn out through the second fixed pipe by the pump body and then sprayed back into the tank at high speed through the first fixed pipe. This process forces all the material to repeatedly pass through the pump body and be subjected to strong mechanical shearing and hydraulic impact in the pump chamber. Combined with the original mechanical stirring inside the tank, this "internal and external" mixing method achieves multiple and high-intensity treatment of the material, which can quickly break down agglomerated particles and make the emulsion or suspension system extremely stable. The independently set valves on each pipeline (first, second, and third valves) allow the operator to precisely control the start and stop of the circulation loop and the flow rate, or isolate specific pipelines for cleaning, making the operation extremely flexible.

[0024] Preferably, the liquid extraction mechanism further includes a liquid storage tank disposed below the support plate, a third fixed pipe that is fixedly connected to the upper end of the liquid storage tank, and a fourth valve body disposed on the third fixed pipe, wherein the upper end of the third fixed pipe is interconnected with the interior of the liquid extraction pipe.

[0025] It is worth noting that the introduction of a storage tank and a third fixed pipe into the liquid extraction mechanism gives the equipment the ability to add and make minor adjustments online. When certain liquid additives (such as surfactants and defoamers) need to be added during the mixing process, the material can be directly added to the storage tank, the fourth valve body can be opened, and the pump body's suction force can be used to accurately and evenly draw it into the main circulation pipeline, and then quickly disperse it throughout the mixing tank with the circulation flow. This avoids the safety risks and air mixing caused by opening the lid to add material. In addition, this design can also be used to pre-feed some bottom material before mixing, or to use circulating cleaning fluid to clean the pipeline and tank online after discharge, which significantly expands the equipment's process adaptability and functionality.

[0026] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0027] 1. This utility model sets up an independent first drive mechanism and a second drive mechanism to drive the first rotating column and its stirring block, and the second rotating column and its stirring mechanism to rotate, respectively. This dual-shaft drive design allows the upper stirring block and the lower fan blades, fixed plate and other components to run at different speeds and directions, creating a composite flow field in the mixing tank. The upper stirring block is responsible for high-speed shearing and crushing of the large particles of material, while the lower fan blades generate a strong radial flow, forcing the material to form a large circulation of up and down in the tank, effectively eliminating the problems of single flow field and low mixing efficiency that are common in conventional single-shaft mixing equipment.

[0028] 2. By setting a second fixed plate with a first groove, a third fixed plate with a second groove, and a column connecting the two on the second rotating column, a cage-like labyrinth channel that rotates with the shaft is formed. When the material is carried by the circulating flow driven by the fan blades and forced to repeatedly pass through these grooves, the rapid change in the flow cross section will generate strong turbulence, shearing and extrusion. This structure increases the mixing strength at the micro level on the basis of mechanical stirring, which can refine and uniformly disperse components such as raw material particles and emulsifiers, significantly improve the micro-homogenization effect on systems containing solid suspended particles or high viscosity, and solve the problem of poor micro-mixing uniformity.

[0029] 3. By installing scrapers at the lower part of the second rotating column that adhere to the bottom surface of the mixing tank, dynamic cleaning of the tank bottom is achieved. During the mixing process, the scrapers rotate continuously, forcibly scraping up denser or incompletely dissolved materials deposited at the bottom and pushing them back into the main circulation flow field. This fundamentally eliminates mixing dead zones and material settling at the bottom, ensuring consistency of product formulation within and between batches. Simultaneously, during the discharge stage, the rotating scrapers guide the material towards the liquid outlet, achieving efficient and low-residue emptying, which improves raw material utilization and facilitates subsequent cleaning.

[0030] 4. By setting up a liquid extraction mechanism including a pump body, a first fixed pipe, a second fixed pipe, and multiple valves, a forced external circulation homogenization loop is constructed. This loop can extract the material from the tank, subject it to high-intensity mechanical shearing and hydraulic impact by the pump body, and then spray it back into the tank at high speed. This "internal and external combined" treatment method greatly enhances the dispersion and emulsification effect of the material, and is especially suitable for herbicide products that require a highly stable suspension system or emulsion. At the same time, the independent setting of each valve allows operators to flexibly control the start and stop of the circulation and the flow rate according to process requirements, making operation convenient and controllable.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] To address the problems of conventional single-shaft mixing equipment in handling complex multi-component systems, such as mixing dead zones, severe material sedimentation at the bottom of the tank, and a lack of efficient circulation homogenization methods, resulting in poor micro-mixing uniformity, long production cycles, and high energy consumption, the following technical solution is proposed. Please refer to [link / reference]. Figures 1-6 ;

[0040] A high-speed homogenizing and mixing device for rice paddy herbicides includes a support plate 1, a mixing tank 2 fixed to the upper end of the support plate 1, a top plate 3 fixed to the upper end of the mixing tank 2, support legs 4 fixed to the four corner edges of the lower end of the support plate 1, a first drive mechanism 5 disposed on the upper end of the top plate 3, a first rotating column 6 rotatably mounted on the top plate 3 via bearings, a second drive mechanism 9 fixed to the lower end of the support plate 1, a second rotating column 8 rotatably mounted on the lower end of the support plate 1 via bearings, and two liquid extraction mechanisms 7 disposed on the outer peripheral wall of the mixing tank 2.

[0041] The upper end of the second rotating column 8 passes through the bottom of the mixing tank 2 and is rotatably supported at the bottom of the mixing tank 2 by a sealed bearing, and the upper end of the second rotating column 8 extends into the interior of the mixing tank 2; a stirring mechanism is provided on the outer peripheral wall of the second rotating column 8, and a second toothed ring 809 is fixedly connected to the lower part of the outer peripheral wall of the second rotating column 8; the second driving mechanism 9 is used to drive the second toothed ring 809.

[0042] The mixing tank 2 is equipped with a liquid outlet mechanism at the lower end and a liquid inlet mechanism at the upper end;

[0043] A first toothed ring 601 is fixedly connected to the upper part of the outer peripheral wall of the first rotating column 6. The first driving mechanism 5 is used to drive the first toothed ring 601. The lower end of the first rotating column 6 passes through the mixing tank 2 and extends into the mixing tank 2. A plurality of stirring blocks 602 are fixedly connected to the lower part of the outer peripheral wall of the first rotating column 6.

[0044] In this embodiment, specifically: the first driving mechanism 5 includes a first fixed base 501 fixed to the upper end of the top plate 3, a first motor 502 fixed to the first fixed base 501, and a first gear 503 fixed to the lower end of the output shaft of the first motor 502. The first gear 503 and the first gear ring 601 mesh with each other.

[0046] In this embodiment, specifically: the stirring mechanism further includes a second fixed plate 803 fixed to the middle of the outer peripheral wall of the second rotating column 8, a first groove 804 penetrating and opened at the upper end of the second fixed plate 803, a plurality of columns 806 fixed to the upper end of the first fixed plate 801, a third fixed plate 807 fixed to the upper end of the plurality of columns 806, and a second groove 808 penetrating and opened at the upper end of the third fixed plate 807.

[0047] In this embodiment, specifically: the stirring mechanism also includes a scraper 805 fixed to the lower part of the outer peripheral wall of the second rotating column 8, and the lower end of the scraper 805 is in contact with the bottom surface of the inner wall of the mixing tank 2.

[0048] In this embodiment, specifically: the liquid outlet mechanism includes a liquid outlet pipe 12 that is fixedly connected to the lower end of the mixing tank 2 and a sixth valve body 13 disposed on the liquid outlet pipe 12. The lower end of the liquid outlet pipe 12 passes through the lower end of the support plate 1 and extends to the lower part of the support plate 1. The liquid inlet mechanism includes two liquid inlet pipes 10 that are fixedly connected to the upper end of the mixing tank 2 and a fifth valve body 11 disposed on the liquid inlet pipe 10. The upper end of the liquid inlet pipe 10 passes through the upper end of the top plate 3 and extends to the upper part of the top plate 3.

[0049] In this embodiment, specifically: the second drive mechanism 9 includes a second fixed base 901 fixed to the lower end of the support plate 1, a second motor 902 fixed to the second fixed base 901, and a second gear 903 fixed to the upper end of the output shaft of the second motor 902. The second gear 903 and the second gear ring 809 mesh with each other.

[0050] In this embodiment, specifically: the liquid extraction mechanism 7 includes a first fixing block 701 fixed to the outer peripheral wall of the mixing tank 2, a first fixing pipe 702 disposed on the inner wall of the first fixing block 701, a first valve body 703 disposed on the first fixing pipe 702, a second fixing block 704 fixed to the outer peripheral wall of the mixing tank 2, a second fixing pipe 705 fixed to the inner wall of the second fixing block 704, a second valve body 706 disposed on the second fixing pipe 705, a pump body 707 disposed outside the support plate 1, a liquid extraction pipe 708 disposed at the liquid extraction end of the pump body 707, and a third valve body 709 disposed on the liquid extraction pipe 708. The liquid extraction end of the liquid extraction pipe 708 is connected to the liquid outlet end of the second fixing pipe 705. The liquid outlet end of the pump body 707 is connected to the liquid inlet end of the first fixing pipe 702 through a pipe. The liquid outlet end of the first fixing pipe 702 passes through the outer peripheral wall of the mixing tank 2 and extends to the inner wall of the mixing tank 2.

[0051] In this embodiment, specifically: the liquid extraction mechanism 7 also includes a liquid storage tank 710 disposed below the support plate 1, a third fixed pipe 711 that is fixedly connected to the upper end of the liquid storage tank 710, and a fourth valve body 712 disposed on the third fixed pipe 711. The upper end of the third fixed pipe 711 is interconnected with the interior of the liquid extraction pipe 708.

[0052] It should be noted that the stirring block 602 at the lower end of the first rotating column 6 is located in the upper region of the inner cavity of the mixing tank 2, while the fan blade 802 and the fixed plate on the second rotating column 8 are located in the middle and lower regions. The two do not overlap in height, ensuring that there is no motion interference when they operate independently.

[0053] Working principle: First, the operator injects various liquid active ingredients, solvents, emulsifiers, and adjuvants required for rice paddy herbicides into the mixing tank 2 according to the formula ratio through the inlet pipe 10 and its fifth valve body 11. After the injection is completed, the fifth valve body 11 is closed. The equipment is started, and the first motor 502 of the first drive mechanism 5 starts to work. Its output shaft drives the first gear 503 to rotate. The first gear 503 drives the first rotating column 6 to rotate at high speed on the top plate 3 through meshing with the first gear ring 601. This drives the multiple stirring blocks 602 at the lower end of the first rotating column 6 to perform high-speed shearing motion in the upper space of the mixing tank 2, generating a strong shearing and dispersing effect on the input materials, breaking up any possible agglomerates or large droplets, and promoting the initial fusion of the components.

[0054] At the same time, the second motor 902 of the second drive mechanism 9 also starts to work, and its output shaft drives the second gear 903 to rotate. The second gear 903 drives the second rotating column 8 to rotate on the support plate 1 through meshing with the second gear ring 809. The rotation of the second rotating column 8 drives the overall operation of the stirring mechanism fixed to it: First, the multiple blades 802 on the first fixed plate 801 generate strong radial thrust, forcing the material to move at high speed from the center of the mixing tank 2 to the tank wall, and forming an up-and-down circulating turbulent flow after impacting the tank wall; Second, the second fixed plate 803 and the third fixed plate 807, which rotate synchronously with the second rotating column 8, and the cage structure formed by the column 806 connecting the two, force the flowing material to repeatedly pass through the first tank 804 and the second tank 808. The rapid change in the flow cross section causes the material to generate strong turbulence, shearing and extrusion, achieving micro-level refinement and homogenization; At the same time, the scraper 805 fixed to the lower part of the second rotating column 8 rotates against the bottom surface of the inner wall of the mixing tank 2, continuously scraping off the material deposited at the bottom of the tank, forcing it to re-participate in the mixing cycle, and completely eliminating the mixing dead zone;

[0055] To further improve the homogenization effect, the operator can turn on the liquid extraction mechanism 7, open the second valve body 706 and the first valve body 703, and start the pump body 707. The material in the mixing tank 2 is extracted through the second fixed pipe 705, flows through the liquid extraction pipe 708 and enters the pump body 707. After being subjected to strong mechanical shearing and hydraulic impact in the pump chamber, it is then sprayed back into the mixing tank 2 at high speed through the pipe and the first fixed pipe 702, forming a forced external circulation. If liquid additives need to be added during the circulation process, the additives can be added to the storage tank 710, the fourth valve body 712 can be opened, and the suction force of the pump body 707 can be used to draw it into the circulation pipeline through the third fixed pipe 711 and evenly disperse it into the mixing tank 2. After the circulation is completed, the pump body 707 and each valve body can be turned off.

[0056] After mixing is complete, the sixth valve 13 on the outlet pipe 12 is opened, and the finished product in the mixing tank 2 is smoothly discharged to the downstream equipment through the outlet pipe 12 under the guidance of the scraper 805, achieving low-residue discharge. Throughout the entire operation, the independently driven dual-shaft stirring system and the external circulating homogenization system work together to achieve efficient and highly uniform mixing of the herbicide materials for paddy fields.
