Description

Technical Field

[0001] This invention relates to the field of flupyradifurone compounding technology, and in particular to a high-efficiency flupyradifurone compounding equipment and method. Background Technology

[0002] High-efficiency flupyridine, chemically known as methyl 2-[4-(5-trifluoromethyl-3-chloro-pyridine-2-oxy)phenoxy]propionate, is rapidly absorbed by the leaves of grassy weeds after application and translocated throughout the plant, inhibiting the growth of meristematic tissue and thus killing the weeds. It has a long residual effect and is highly effective against both annual and perennial grassy weeds from emergence to tillering and early heading stages. Under normal use, it is highly safe for various broadleaf crops. It also exhibits excellent weed control under low temperature and drought conditions.

[0003] In existing technologies, high-efficiency flupyridine is usually compounded with other herbicides to form formulations that have multiple herbicidal effects. High-efficiency flupyridine formulations are mainly single-agent emulsifiable concentrates, microemulsions, suspension concentrates, and compound emulsifiable concentrates and suspension concentrates with other pesticides.

[0004] When compounding high-efficiency flupyridine, the high-efficiency flupyridine and the pesticides to be compounded need to be mixed evenly in the oil phase. Then, the aqueous phase, composed of surfactant, stabilizer and water, is poured into the oil phase and rapidly sheared and stirred until it is mixed into an emulsion suspension, which is then ready for compounding and use.

[0005] In existing high-efficiency flupyradifurone formulations, the aqueous phase is usually poured in from above the oil phase for mixing. The contact area between the aqueous and oil phases is only the upper part of the oil phase, making it difficult for the aqueous phase to disperse within the oil phase. As a result, the mixing speed of high-efficiency flupyradifurone formulations is slow and the efficiency is low. Summary of the Invention

[0006] To address the problems mentioned in the background section, this invention provides a highly efficient flupyridine compounding device and method.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A high-efficiency flupyradifurone compounding device includes a fixed outer tank, a rotating inner tank, and a central rotating shaft. The rotating inner tank is coaxially installed inside the fixed outer tank, and the central rotating shaft is installed at the central axis of the rotating inner tank. Multiple stirring rods are installed on the inner peripheral wall of the rotating inner tank and the outer peripheral wall of the central rotating shaft. The central rotating shaft is hollow inside, and the outer peripheral wall of the rotating inner tank has a liquid-distributing ring cavity. The stirring rod includes a stirring main rod, a liquid flow driving wheel, a rotation transmission component, a centrifugal wheel plate, and a spiral conveying component. The stirring main rod has a delivery chamber, a pumping chamber, and a transmission chamber connected in sequence inside. The delivery chamber is connected to the inside of the central rotating shaft or the liquid-distributing ring cavity.

[0009] The stirring rod has a liquid flow window that connects to the transmission chamber and a pumping window that connects to the pumping chamber. The liquid flow drive wheel is installed in the transmission chamber, the centrifugal wheel plate is installed in the pumping chamber, and the screw conveyor is installed in the delivery chamber. The liquid flow drive wheel, the centrifugal wheel plate, and the screw conveyor can rotate coaxially.

[0010] Preferably, the upper end of the rotating inner tank is provided with an open liquid receiving ring groove, and a side liquid inlet pipe is provided above the liquid receiving ring groove. The liquid separating ring cavity is divided into multiple non-communicating chambers by multiple liquid separating plates according to the setting position of the stirring rod. Each chamber is connected to the liquid receiving ring groove through a liquid transfer pipe.

[0011] Preferably, the upper end of the central rotating shaft is open, and a central liquid inlet pipe is installed at the center position of the top plate of the fixed outer tank. The central liquid inlet pipe can guide the external aqueous phase into the interior of the central rotating shaft.

[0012] Preferably, the rotary transmission component includes a fixed fitting component, a fixed column, a return spring, and a fitting rotating plate. The fixed fitting component is installed on the side of the centrifugal wheel plate, and the fitting rotating plate is coaxially installed on the side of the liquid flow driving wheel. The fitting rotating plate is sleeved outside the fixed column. The fitting rotating plate is locked to the fixed column in the rotation direction, but can move horizontally along the fixed column. The two ends of the return spring are respectively connected to the fitting rotating plate and the liquid flow driving wheel.

[0013] Preferably, the centrifugal wheel plate includes an isolation plate and a centrifugal vortex plate. The isolation plate is vertically installed in the transmission cavity, which also isolates the transmission cavity from the pumping cavity.

[0014] Preferably, the centrifugal vortex plate includes a bent main plate, a counterweight, a limiting plate, a movable partition, and a connecting beam. The bent main plate has a cavity inside, which extends from the side of the centrifugal vortex plate toward the center of the partition plate to the outside. The connecting beam is fixed to the upper part of the bent main plate on the centrifugal side toward the center and connects two adjacent bent main plates. The movable partition is inserted into the cavity and can move within the cavity to extend out. After extending out of the cavity, the movable partition cooperates with the connecting beam to independently enclose the center position of the partition plate.

[0015] Preferably, the limiting plate is installed inside the setting cavity, and a connecting spring is installed between the movable partition and the limiting plate. The connecting spring can push the movable partition out of the setting cavity when it is at its normal length. The counterweight is set on the side of the limiting plate away from the movable partition. The counterweight and the movable partition are connected by a pull rope, and the counterweight can move freely inside the setting cavity.

[0016] A highly efficient method for compounding flupyradifurone includes the following steps:

[0017] S1: Mix the high-efficiency flumethrin technical, the other herbicide technicals and solvent to dissolve the high-efficiency flumethrin technical and the other herbicide technicals to obtain a uniform oil phase;

[0018] S2: Mix surfactant, stabilizer and water to obtain a homogeneous aqueous phase;

[0019] S3: Inject the oil phase obtained in S1 into the rotating inner tank, and inject the water phase obtained in S1 into the central rotating shaft and the liquid separation ring cavity.

[0020] S4: Start the motor to drive the central rotating shaft and the rotating inner tank to rotate at a low speed, so that the liquid flow drives the wheel to rotate. When the centrifugal wheel rotates, the central area is opened to allow the liquid phase to flow into the rotating inner tank.

[0021] S5: After adding a predetermined volume of liquid, increase the rotation speed of the central rotating shaft and the rotating inner tank. The rotating transmission components stop rotating under high centrifugal force, and the central area is resealed after the centrifugal wheel stops rotating.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] 1. The rotating inner tank and the central rotating shaft of the present invention can drive the stirring rods installed on their peripheral walls to rotate independently. The stirring rods installed on the inner peripheral wall of the rotating inner tank and the stirring rods installed on the outer peripheral wall of the central rotating shaft can rotate in opposite directions, resulting in better stirring effect and higher efficiency.

[0024] 2. In this invention, the liquid phase added externally is released into the rotating inner tank through multiple stirring rods immersed in the oil phase. The injection points are dispersed, and the release is completed while the stirring rods are rotating and stirring, resulting in more uniform dispersion of the water phase and high stirring efficiency.

[0025] 3. In this invention, the release of the aqueous phase is controlled by adjusting the rotation speed of the stirring rod and using the centrifugal force of the rotating plate. After the centrifugal plate stops rotating, it automatically isolates and seals the infusion chamber. The control method is simple and can be accurately achieved when the stirring rod is rotating at high speed. The equipment is stable and efficient. Attached Figure Description

[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Reference Figure 1-6 A high-efficiency fluopyram compounding device includes a fixed outer tank 1, a rotating inner tank 2, and a central rotating shaft 3. The rotating inner tank 2 is coaxially installed inside the fixed outer tank 1 and can be driven by a motor installed at the bottom to rotate axially within the fixed outer tank 1. The central rotating shaft 3 is installed at the central axis of the rotating inner tank 2 and can be driven to rotate axially within the rotating inner tank 2. Multiple stirring rods 4 are symmetrically installed on the inner circumferential wall of the rotating inner tank 2 and the outer circumferential wall of the central rotating shaft 3. The stirring rods 4 are horizontally arranged and arranged in multiple groups vertically.

[0036] The upper end of the rotating inner tank 2 is provided with an open liquid receiving ring groove 201. A side liquid inlet pipe 11 is provided above the liquid receiving ring groove 201, allowing external aqueous phase to be injected into the liquid receiving ring groove 201 through the side liquid inlet pipe 11. The outer peripheral wall of the rotating inner tank 2 has a liquid distribution ring cavity 202. The liquid distribution ring cavity 202 is divided into multiple non-communicating chambers by multiple liquid distribution plates 21 according to the setting position of the stirring rod 4. Each chamber is connected to the liquid receiving ring groove 201 through a transfer pipe 22. The liquid flowing into the liquid receiving ring groove 201 will flow downward through the transfer pipe 22 into each chamber of the liquid distribution ring cavity 202. The stirring rod 4 installed on the inner peripheral wall of the rotating inner tank 2 is connected to the chamber of the liquid distribution ring cavity 202 at the same height.

[0037] The central rotating shaft 3 is hollow inside. The stirring rod 4, which is installed on the outer peripheral wall of the central rotating shaft 3, is connected to the inside of the central rotating shaft 3. The upper end of the central rotating shaft 3 is open and a driven gear 5 is installed. A side motor is installed on the top plate of the fixed outer tank 1. The side motor can drive the gear meshing with the driven gear 5 to rotate, thereby driving the central rotating shaft 3 to rotate axially. A central liquid inlet pipe 12 is installed at the center of the top plate of the fixed outer tank 1. The central liquid inlet pipe 12 can guide the external aqueous phase into the interior of the central rotating shaft 3.

[0038] When the rotating inner tank 2 and the central rotating shaft 3 rotate axially, the stirring rods 4 installed on the inner peripheral wall of the rotating inner tank 2 and the outer peripheral wall of the central rotating shaft 3 can shear and stir the liquid inside the rotating inner tank 2. During the rotation of the rotating inner tank 2 and the central rotating shaft 3, the water phase flowing into the liquid distribution ring cavity 202 and the interior of the central rotating shaft 3 can enter the interior of the rotating inner tank 2 through the stirring rods 4, and the liquid phase can enter the interior of the rotating inner tank 2 from multiple points through the stirring rods 4 and mix rapidly with the oil phase.

[0039] Specifically, the stirring rod 4 includes a stirring main rod 41, a liquid flow drive wheel 42, a rotary transmission component 43, a centrifugal wheel plate 44, and a spiral conveyor component 45. The stirring main rod 41 has a liquid delivery chamber 401, a pumping chamber 402, and a transmission chamber 403 connected in sequence inside. The liquid delivery chamber 401 is connected to the interior of the central rotating shaft 3 or the liquid distribution ring chamber 202.

[0040] The transmission chamber 403 of the stirring rod 4, located on the inner circumferential wall of the rotating inner tank 2, faces the central rotation axis 3. The liquid flow drive wheel 42 is installed inside the transmission chamber 403 and can rotate axially within it. The stirring rod 4 has a liquid flow window 404 communicating with the transmission chamber 403, which in turn connects to the interior of the rotating inner tank 2. The liquid flow drive wheel 42 has impeller blades on its exterior. When the stirring rod 4 rotates inside the rotating inner tank 2, the liquid inside the tank contacts and pushes the impeller blades, thereby driving the liquid flow drive wheel 42 to rotate axially.

[0041] The rotary transmission component 43 includes a fixed fitting component 431, a fixed column 432, a return spring 433, and a mating rotating plate 434. The centrifugal wheel plate 44 is axially rotatably fixedly installed in the pumping chamber 402. The fixed fitting component 431 is installed on the side of the centrifugal wheel plate 44 facing the liquid flow driving wheel 42. The mating rotating plate 434, which can dock with the fixed fitting component 431, is coaxially installed on the side of the liquid flow driving wheel 42. When the mating rotating plate 434 docks with the fixed fitting component 431, the liquid flow driving wheel 42 can drive the centrifugal wheel plate 44 to rotate axially together when it is driven to rotate by the liquid.

[0042] The rotating plate 434 is sleeved on the outside of the fixed column 432. The rotating plate 434 is locked to the fixed column 432 in the rotation direction, but can move horizontally along the fixed column 432. The two ends of the return spring 433 are respectively connected to the rotating plate 434 and the liquid flow drive wheel 42. Under normal circumstances, the rotating plate 434 is pushed to engage with the fixed fitting part 431. As the rotation speed of the inner tank 2 increases, the rotating plate 434 will be subjected to increasingly larger centrifugal forces. The centrifugal forces on the rotating plate 434 will overcome the elastic force of the return spring 433 and push the rotating plate 434 away from the fixed fitting part 431. When the rotating plate 434 moves and completely disengages from the fixed fitting part 431, the liquid flow drive wheel 42 can no longer drive the centrifugal wheel plate 44 to rotate.

[0043] The centrifugal wheel plate 44 includes an isolation plate 441 and a centrifugal vortex plate 442. The isolation plate 441 is vertically installed in the transmission cavity 403, isolating the transmission cavity 403 from the pumping cavity 402, and can be driven by the fixed fitting 431 to rotate axially. The centrifugal vortex plate 442 is circumferentially symmetrically installed on the side of the isolation plate 441 away from the fixed fitting 431. When the centrifugal wheel plate 44 rotates axially, the liquid flowing into the center of the centrifugal vortex plate 442 will be thrown to the edge by the centrifugal vortex plate 442. The stirring rod 41 has a pumping window 405 communicating with the pumping cavity 402. The liquid phase thrown out by the centrifugal vortex plate 442 and tending to flow towards the periphery of the pumping cavity 402 will flow into the interior of the rotating inner tank 2 through the pumping window 405 and mix rapidly with the oil phase.

[0044] The spiral conveyor 45 is disposed in the infusion chamber 401. The spiral conveyor 45 is coaxially connected to the isolation plate 441. The surface of the spiral conveyor 45 has a spiral curved surface. When the spiral conveyor 45 is axially rotated synchronously by the centrifugal wheel plate 44, the liquid phase flowing into the infusion chamber 401 from the inside of the central rotating shaft 3 or the liquid distribution ring cavity 202 will be continuously pushed by the spiral conveyor 45 to the center position of the centrifugal vortex plate 442.

[0045] The centrifugal vortex plate 442 includes a bent main plate 4421, a counterweight 4422, a limiting plate 4423, a movable partition plate 4424, and a connecting beam 4425. The bent main plate 4421 has a cavity 406 inside, which extends from the side of the centrifugal vortex plate 442 towards the center of the partition plate 441 to the outside. The connecting beam 4425 is fixed to the upper part of the bent main plate 4421 on the centrifugal side and connects two adjacent bent main plates 4421. The movable partition plate 4424 is inserted into the cavity 406. Furthermore, it can move within the setting cavity 406 and extend out from it. After the movable partition 4424 extends out from the setting cavity 406, it cooperates with the connecting beam 4425 to independently enclose the center position of the partition 441. At this time, the liquid phase in the infusion cavity 401 will be blocked by the movable partition 4424 and the connecting beam 4425 after flowing into the pumping cavity 402 and will not be able to flow to the pumping window 405. Similarly, the oil phase that flows back into the pumping cavity 402 from the rotating inner tank 2 through the pumping window 405 will also be blocked and will not be able to flow into the infusion cavity 401.

[0046] The limiting plate 4423 is installed in the setting cavity 406. A connecting spring 4426 is installed between the movable partition 4424 and the limiting plate 4423. The connecting spring 4426 can push the movable partition 4424 out of the setting cavity 406 to block it when it is at its normal length. The counterweight 4422 is located on the side of the limiting plate 4423 away from the movable partition 4424. The counterweight 4422 and the movable partition 4424 are connected by a pull rope. The counterweight 4422 can move freely in the setting cavity 406.

[0047] When the centrifugal wheel plate 44 is stationary, the infusion chamber 401 and the pumping chamber 402 are isolated by the movable partition 4424 extending out of the setting chamber 406. When the centrifugal wheel plate 44 rotates axially, the counterweight 4422, which is closer to the outer edge of the centrifugal vortex plate 442 and is heavier, can pull the partition plate 441 into the setting chamber 406 under the action of centrifugal force. At this time, the infusion chamber 401 and the pumping chamber 402 are connected, and the liquid phase will continuously flow to the pumping chamber 402 and out of the pumping window 405.

[0048] The centrifugal wheel plate 44 of the stirring rod 4 is set close to the central rotating shaft 3. After the liquid phase flows out of the stirring rod 4, it approaches the central rotating shaft 3 and diffuses to the outer edge of the rotating inner tank 2 under the action of centrifugal force of the liquid rotation in the rotating inner tank 2, so that the oil phase and the liquid phase are mixed more evenly and quickly.

[0049] A highly efficient method for compounding flupyradifurone includes the following steps:

[0050] S1: Mix the high-efficiency flumethrin technical, the other herbicide technicals and solvent to dissolve the high-efficiency flumethrin technical and the other herbicide technicals to obtain a uniform oil phase;

[0051] S2: Mix surfactant, stabilizer and water to obtain a homogeneous aqueous phase;

[0052] S3: Inject the oil phase obtained in S1 into the rotating inner tank 2, and inject the water phase obtained in S1 into the central rotating shaft 3 and the liquid separation ring cavity 202.

[0053] S4: Start the motor to drive the central rotating shaft 3 and the rotating inner tank 2 to rotate at a low speed, so that the liquid flow drives the liquid flow wheel 42 to rotate. When the centrifugal wheel plate 44 rotates, it opens the central area and allows the liquid phase to flow into the rotating inner tank 2.

[0054] S5: After the liquid phase is added to a predetermined volume, the rotation speed of the central rotating shaft 3 and the rotating inner tank 2 is increased. The rotating transmission component 43 stops rotating under high centrifugal force. After the centrifugal wheel plate 44 stops rotating, the central area is resealed.
