Description

Technical Field

[0001] The invention belongs to the technical field of pesticide processing, and in particular relates to a cyhalofop-butyl aqueous emulsion preparation device and a preparation method thereof. Background Art

[0002] Chemical herbicides are important products used to control agricultural weeds. Since chemical weed control has the advantages of high efficiency, rapidity and economy, and some varieties also have the advantage of promoting crop growth, it is an advanced technology that is indispensable for greatly improving labor productivity and realizing agricultural modernization, and has become an important guarantee for high and stable agricultural production. Therefore, herbicides are of great significance for the development of agricultural, forestry and animal husbandry production and ensuring high agricultural yields and harvests. In recent years, the herbicide cyhalofop-butyl has received more and more attention due to its high efficiency and safety. Cyhalofop-butyl is a highly efficient and selective systemic stem and leaf treatment herbicide, which is mainly used for the control of annual and perennial grass weeds.

[0003] In the process of preparing the cyhalofop-butyl aqueous emulsion, it is necessary to first prepare the water phase and the oil phase by a stirring device respectively, then pour the water phase into a magnetic stirrer, slowly add the oil phase into the water phase under the stirring condition of the magnetic stirrer, mix the two phases evenly into a crude emulsion, pour the crude emulsion into an emulsion high shear emulsifier, and then shear the cyhalofop-butyl aqueous emulsion by a high shear emulsifier. In the existing production equipment, the water phase and the oil phase are stirred by a stirrer respectively, and the two stirrers are connected to the magnetic stirrer by a pipeline respectively. After the water phase and the oil phase are stirred and prepared, the channel between the water phase and the magnetic stirrer is opened first, and then the channel between the oil phase and the magnetic stirrer is opened. Once the sequence is wrong, the product will be directly scrapped. In production, the opening of each channel is usually opened by the operator starting the button, and an unskilled operator or an operator who is careless may mistakenly open the sequence of opening the channel, making the product scrapped. Summary of the invention

[0004] In view of the deficiencies in the prior art, the object of the present invention is to provide a device for preparing a cyhalofop-butyl emulsion in water and a method for preparing the same, so as to solve the technical problem that the order of adding the water phase and the oil phase may be wrong during the preparation of the cyhalofop-butyl emulsion in water mentioned in the background body above.

[0005] In order to achieve the above-mentioned invention object, the technical solution adopted by the present invention includes:

[0006] A cyhalofop-butyl aqueous emulsion preparation device comprises a high shear emulsifier, a raw material mixer and a magnetic mixer;

[0007] The raw material mixer comprises a body, a partition plate, a stirring mechanism, a water phase feeding component, an oil phase feeding component, a driving mechanism and a transmission mechanism;

[0008] The partition plate divides the body into two parts that are not connected to each other, and are connected to the magnetic stirrer through the water phase discharge assembly and the oil phase discharge assembly respectively. The stirring mechanism is arranged on the body and can stir the two parts separated by the partition plate.

[0009] The driving mechanism can be raised and lowered on the body and connected to the water-phase discharge assembly, and the lifting of the driving mechanism can drive the water-phase discharge assembly to open; the transmission mechanism can be rotatably disposed on the body and connected to the oil-phase discharge assembly, and the descent of the driving mechanism can drive the transmission mechanism to rotate unidirectionally, and the rotation of the transmission mechanism can drive the oil-phase discharge assembly to open and close.

[0010] Furthermore, the driving mechanism includes a driving member and a rack; the driving member is arranged on the machine body and connected to the rack, and the rack is slidably connected to the machine body in a liftable manner. Specifically, the driving member is arranged on the base of the machine body, and the rack is slidably connected to the outer wall of the mixing barrel of the machine body.

[0011] Furthermore, the water phase discharge assembly includes a water phase discharge pipe, a water phase closing plate and a water phase connecting rod; one end of the water phase discharge pipe is connected to the fuselage, and the other end is connected to the magnetic stirrer; the water phase closing plate can be raised and lowered and slidably connected in the water phase discharge pipe, and is connected to the driving mechanism through the water phase connecting rod.

[0012] Furthermore, the oil phase discharge assembly includes an oil phase discharge pipe and an oil phase sealing plate; one end of the oil phase discharge pipe is connected to the machine body, and the other end is connected to the magnetic stirrer; the oil phase sealing plate is slidably connected to the oil phase discharge pipe and connected to the transmission mechanism. Preferably, the water phase discharge pipe and the oil phase discharge pipe are respectively arranged obliquely downward, and the diameter of the oil phase discharge pipe is smaller than that of the water phase discharge pipe.

[0013] Further, the transmission mechanism includes a transmission gear ring, a driven component, a connecting component and a limiting component; the transmission gear ring, the driven component and the limiting component are rotatably connected to the body, the transmission gear ring is meshed with the rack, the inner wall of the transmission gear ring is circumferentially provided with ratchets, and the lifting and lowering of the rack can drive the transmission gear ring to rotate; the driven component is coaxially arranged in the transmission gear ring, and the rotation of the transmission gear ring can drive the driven component to rotate forward in one direction through the ratchets, and the forward rotation of the driven component can drive the oil phase sealing plate to lift and lower through the connecting component; the limiting component abuts against the driven component and can limit the reverse rotation of the driven component. It should be understood that the rack is always meshed with the transmission gear ring.

[0014] Furthermore, the driven assembly includes a turntable, a driven coupling, a driven pawl, a driven torsion spring, a connecting shaft and a ratchet; the turntable is rotatably connected to the body and is coaxially located inside the transmission gear ring; the driven coupling is eccentrically arranged on the turntable, the driven pawl is rotatably arranged on the driven coupling and is connected to the turntable through the driven torsion spring, and the rotation of the ratchet can drive the turntable to rotate unidirectionally through the pawl; the connecting shaft is coaxially fixed on the turntable and is connected to the oil phase sealing plate through the connecting assembly; the ratchet is coaxially fixed on the connecting shaft, and the limiting assembly can limit the reversal of the ratchet. This structure can make the connecting shaft rotate unidirectionally, and the limiting assembly limits the reversal of the ratchet, that is, limits the reversal of the connecting shaft, so that when the connecting assembly lifts the oil phase sealing plate to the highest point, the gravity of the oil phase sealing plate itself is prevented from driving the connecting shaft to rotate in the opposite direction.

[0015] Further, the connection assembly includes a connection plate and a driven plate; the connection plate is fixedly connected to the connection shaft, one end of the driven plate is hinged to the connection plate, and the other end is hinged to the oil phase sealing plate. It should be understood that the connection shaft, the connection plate, the driven plate and the oil phase sealing plate can be approximately regarded as a crank slider mechanism.

[0016] Further, the limiting assembly includes a limiting coupling, a limiting pawl and a limiting torsion spring; the limiting coupling is fixedly mounted on the body, the limiting pawl is rotatably mounted on the limiting coupling and connected to the body via the torsion spring, and the limiting pawl can limit the reverse rotation of the ratchet wheel. Specifically, the limiting coupling is located outside the transmission gear ring.

[0017] Furthermore, the oil phase sealing plate is a telescopic plate, and when the oil phase sealing plate is at the highest point of the stroke, it can give the connecting shaft a tendency to reverse. Specifically, when the oil phase sealing plate is at the highest point, the angle between the connecting plate and the driven plate is an acute angle, and the hinge point is far away from the rack. This arrangement can prevent the gravity of the oil phase sealing plate from driving the ratchet wheel to rotate forward and causing the oil phase sealing plate to fall accidentally.

[0018] A method for preparing cyhalofop-butyl emulsion in water mainly comprises the following steps:

[0019] S1, respectively putting the raw materials for preparing the water phase and the raw materials for preparing the oil phase into the raw material mixer;

[0020] S2, start the stirring mechanism;

[0021] S3, starting the driving mechanism to lift the driving mechanism to the top, thereby opening the water phase discharge assembly, and starting the magnetic stirrer after the water phase has finished flowing out;

[0022] S4, starting the driving mechanism to make it descend to the lowest end, thereby opening the oil phase unloading component;

[0023] S5, after the oil phase is discharged, the driving mechanism is started to complete the lifting again, so that the water phase discharge component and the oil phase discharge component are both closed;

[0024] S6. Send the crude emulsion stirred by the magnetic stirrer into a high shear emulsifier for shearing.

[0025] Compared with the prior art, the advantages of the present invention include:

[0026] In the present application, the preparation of the oil phase and the water phase is concentrated in the same equipment. Through two lifting and lowering operations of the same driving mechanism, the water phase flows into the magnetic stirrer first and the oil phase flows into the magnetic stirrer later. By operating the same mechanism and the same button, the possibility of incorrect order of adding the water phase and the oil phase that may occur when operating multiple buttons is reduced.

[0039] The embodiment of the present invention is intended to introduce and illustrate the structural composition of the cyhalofop-butyl emulsion in water preparation device and the coordination relationship between the various components. Unless otherwise specified, the size, material and manufacturing process of each component in the cyhalofop-butyl emulsion in water preparation device in the embodiment of the present invention can be selected according to the specific situation and are not specifically limited or described herein.

[0040] Further, in order to make the public have a better understanding of the present invention, some specific details are described in detail in the following detailed description of the present invention. For those skilled in the art, the present invention can be fully understood without the description of these details.

[0041] Please also read Figure 1-Figure 4 This embodiment provides a cyhalofop-butyl aqueous emulsion preparation device, including a high shear emulsifier, a raw material mixer 1 and a magnetic mixer 10;

[0042] The raw material mixer 1 comprises a body 11, a partition plate 12, a stirring mechanism 13, a water phase feeding assembly 2, an oil phase feeding assembly 3, a driving mechanism 4 and a transmission mechanism 5;

[0043] The partition plate 12 separates the body 11 into two parts that are not connected to each other, and are connected to the magnetic stirrer through the water phase discharge component 2 and the oil phase discharge component 3 respectively. The stirring mechanism 13 is arranged on the body 11, and can stir the two parts separated by the partition plate 12; specifically, the body 11 is divided into a base and a stirring barrel, and the partition plate 12 separates the stirring barrel into two parts that are isolated from each other in the upper and lower parts, that is, the side surfaces of the partition plate 12 are in contact with the inner wall of the stirring barrel, and the interior of the stirring barrel is divided into a water phase area and an oil phase area that are not connected to each other. In this embodiment, the oil phase area is in the upper part and the water phase area is in the lower part. The water phase area is connected to the magnetic stirrer 10 through the water phase discharge component 2, and the oil phase area is connected to the magnetic stirrer 10 through the oil phase discharge component 3; the stirring barrel is provided with feeding pipes or feeding ports corresponding to the water phase area and the oil phase area, respectively, and preferably, the feeding pipes or feeding ports can be switched.

[0044] The driving mechanism 4 is rotatably disposed on the body 11 and connected to the water-phase material discharge assembly 2. The lifting of the driving mechanism 4 can drive the water-phase material discharge assembly 2 to open; that is, the lifting of the driving mechanism 4 can open the water-phase material discharge assembly 2, and the lowering of the driving mechanism 4 can close the water-phase material discharge assembly 2. The transmission mechanism 5 is rotatably disposed on the body 11 and connected to the oil-phase material discharge assembly 3. The lowering of the driving mechanism 4 can drive the transmission mechanism 5 to rotate unidirectionally, and the rotation of the transmission mechanism 5 can drive the oil-phase material discharge assembly 3 to open and close.

[0045] The descent of the driving mechanism 4 drives the transmission mechanism 5 to rotate in one direction, that is, the driving mechanism 4 can only drive the transmission mechanism 5 to rotate and then open and close the oil-phase material discharge component 3 when it descends. Specifically, the two ascents and descents of the driving mechanism 4 constitute one cycle. When the driving mechanism 4 descends for the first time, the oil-phase material discharge component 3 is opened through the transmission mechanism 5, and when the driving mechanism 4 descends for the second time, the oil-phase material discharge component 3 is closed through the transmission mechanism 5. It should be understood that when the driving mechanism 4 descends to the lowest point and remains stationary, the oil-phase material discharge component 3 can remain open or closed.

[0046] Specifically, in the initial state, the water phase feeding component 2 and the oil phase feeding component 3 are both in the closed state. When the water phase and the oil phase are prepared, the driving mechanism 4 is started to lift the driving mechanism 4. During this process, the water phase feeding component 2 is opened and the oil phase feeding component 3 remains closed; after the water phase flows out, the driving mechanism 4 is started to lower the driving mechanism 4. During this process, the water phase feeding component 2 is closed and the oil phase feeding component 3 is opened; after the oil phase flows out, the driving mechanism 4 is started to complete another lifting and lowering. During this lowering process, the oil phase feeding component 3 and the water phase feeding component 2 are both closed.

[0047] It is worth mentioning that the stirring mechanism 13 includes a motor, a stirring rod and a stirring blade, etc. The stirring rod is preferably placed through the partition plate 12 in the water phase area and the oil phase area, and is leak-proof and isolated with leak-proof pads, rubber pads, etc., so that the liquid in the oil phase area will not leak into the water phase area.

[0048] In the present application, the preparation of the oil phase and the water phase is concentrated in the same device. By raising and lowering the same driving mechanism 4 twice, the water phase flows into the magnetic stirrer 10 first and the oil phase flows into the magnetic stirrer 10 later. By operating the same mechanism and the same button, the possibility of an error in the order of adding the water phase and the oil phase that may occur when operating multiple buttons is reduced.

[0049] In other embodiments, the driving mechanism 4 includes a driving member 41 and a rack 42; the driving member 41 is provided on the body 11 and connected to the rack 42, and the rack 42 is slidably connected to the body 11 so as to be able to be raised and lowered. It should be understood that the driving member 41 is a part that can drive the rack 42 to be raised and lowered, and can preferably be a cylinder, a linear motor, etc. Specifically, the driving member 41 is provided on the base of the body 11, and the rack 42 is slidably connected to the outer wall of the mixing barrel of the body 11.

[0050] In other embodiments, the water phase discharge assembly 2 includes a water phase discharge pipe 21, a water phase sealing plate 22 and a water phase connecting rod 23; one end of the water phase discharge pipe 21 is connected to the body 11, and the other end is connected to the magnetic stirrer 10; the water phase sealing plate 22 is slidably connected to the water phase discharge pipe 21 and is connected to the driving mechanism 4 through the water phase connecting rod 23. Specifically, the water phase connecting rod 23 is connected to the rack 42, and the top of the water phase connecting pipe is provided with an opening that can just pass through the water phase sealing plate 22, and the water phase sealing plate 22 is always located in the opening.

[0051] In other schemes, the oil phase discharge assembly 3 includes an oil phase discharge pipe 31 and an oil phase sealing plate 32; one end of the oil phase discharge pipe 31 is connected to the fuselage 11, and the other end is connected to the magnetic stirrer 10, and the oil phase sealing plate 32 can be raised and lowered and slidably connected to the oil phase discharge pipe 31, and is connected to the transmission mechanism 5.

[0052] Specifically, the top of the oil-phase connecting pipe is provided with an opening corresponding to the oil-phase connecting plate 81, and the oil-phase sealing plate 32 is always located in the opening. Preferably, the water-phase discharge pipe 21 and the oil-phase discharge pipe 31 are respectively arranged obliquely downward, and the diameter of the oil-phase discharge pipe 31 is smaller than that of the water-phase discharge pipe 21.

[0053] In other schemes, the transmission mechanism 5 includes a transmission gear ring 6, a driven component 7, a connecting component 8 and a limiting component 9; the transmission gear ring 6, the driven component 7 and the limiting component 9 are respectively rotatably connected to the body 11, the transmission gear ring 6 is meshed with the rack 42, the inner wall of the transmission gear ring 6 is circumferentially provided with ratchets, and the lifting and lowering of the rack 42 can drive the transmission gear ring 6 to rotate; the driven component 7 is coaxially arranged in the transmission gear ring 6, and the rotation of the transmission gear ring 6 can drive the driven component 7 to rotate forward in one direction through the ratchets, and the forward rotation of the driven component 7 can drive the oil phase sealing plate to rise and fall through the connecting component 8; specifically, the lifting of the rack 42 drives the transmission gear ring 6 to reverse, and the reverse rotation of the transmission gear ring 6 does not drive the driven component 7 to rotate as a whole; the descent of the rack 42 drives the transmission gear ring 6 to rotate forward, and the reverse rotation of the transmission gear ring 6 drives the driven component 7 to rotate forward as a whole, and the oil phase sealing plate 32 is lifted and lowered through the connecting component 8. The limiting component 9 abuts against the driven component 7 and can limit the reverse rotation of the driven component 7.

[0054] Specifically, the forward rotation of the driven component 7 drives the limiting component 9 to rotate and move away from the driven component 7. When the driven component 7 has a reverse rotation tendency, the limiting component 9 can resist the transmission component to limit its reverse rotation. The transmission gear ring 6, the driven component 7 and the limiting component 9 are respectively rotatably connected to the outer wall of the mixing barrel of the machine body 11. It should be understood that the rack 42 is always engaged with the transmission gear ring 6.

[0055] In other embodiments, the driven assembly 7 includes a rotating disk 71, a driven coupling shaft 72, a driven pawl 73, a driven torsion spring 74, a connecting shaft 75 and a ratchet 76; the rotating disk 71 is rotatably connected to the body 11 and is coaxially located inside the transmission gear ring 6; the driven coupling shaft 72 is eccentrically arranged on the rotating disk 71, and the driven pawl 73 is rotatably arranged on the driven coupling shaft 72 and connected to the rotating disk 71 through the driven torsion spring 74. The rotation of the ratchet can be unidirectionally driven by the pawl. Drives the turntable 71 to rotate; specifically, when the rack 42 is lifted and drives the transmission gear ring 6 to rotate in the opposite direction, the ratchet teeth of the transmission gear ring 6 repeatedly drives the driven pawl 73 to rotate around the axis of the driven connecting shaft 72 and away from the ratchet teeth; when the rack 42 descends and drives the transmission gear to rotate forward, the angle between the driven connecting shaft 72 and the driven pawl 73 remains stationary, and the ratchet teeth of the transmission gear ring 6 abut and drive the pawl to rotate around the axis of the turntable 71, that is, drives the turntable 71 to rotate together.

[0056] The connecting shaft 75 is coaxially fixed on the rotating disk 71 and connected to the oil phase sealing plate 32 through the connecting component 8; the ratchet 76 is coaxially fixed on the connecting shaft 75, and the limiting component 9 can limit the reverse rotation of the ratchet 76.

[0057] This structure enables the connecting shaft 75 to rotate in one direction, and the limiting component 9 limits the ratchet 76 from reversing, that is, limits the connecting shaft 75 from reversing, so that when the connecting component 8 lifts the oil phase sealing plate 32 to the highest point, the gravity of the oil phase sealing plate 32 itself is prevented from driving the connecting shaft 75 to rotate in the opposite direction.

[0058] In other embodiments, the connecting assembly 8 includes a connecting plate 81 and a driven plate 82; the connecting plate 81 is fixedly connected to the connecting shaft 75, and one end of the driven plate 82 is hinged to the connecting plate 81, and the other end is hinged to the oil phase sealing plate. It should be understood that the connecting shaft 75, the connecting plate 81, the driven plate 82 and the oil phase sealing plate 32 can be approximately regarded as a crank slider mechanism.

[0059] In other embodiments, the limiting assembly 9 includes a limiting coupling 91, a limiting pawl 92 and a limiting torsion spring 93; the limiting coupling 91 is fixedly mounted on the body 11, the limiting pawl 92 is rotatably mounted on the limiting coupling 91 and connected to the body 11 via the torsion spring, and the limiting pawl 92 can limit the reverse rotation of the ratchet wheel 76. Specifically, the limiting coupling 91 is located outside the transmission gear ring 6.

[0060] In other embodiments, the oil phase sealing plate 32 is a telescopic plate, and the oil phase sealing plate 32 can give the connecting shaft 75 a tendency to reverse when it is at the highest point of the stroke. Specifically, when the oil phase sealing plate 32 is at the highest point, the angle between the connecting plate 81 and the driven plate 82 is an acute angle, and the hinge point is far away from the rack 42. This arrangement can prevent the oil phase sealing plate 32 from accidentally falling due to the weight of the oil phase sealing plate 32 driving the ratchet 76 to rotate forward.

[0061] The bottom of the telescopic plate is slidably connected to the oil phase discharge pipe 31 and can close the oil phase discharge pipe 31. The top of the telescopic plate is hinged to the driven plate 82. Each time the rack 42 descends, it will drive the rotation 180°. During the second lifting and descending of the rack 42 to the lowest point, the driven plate 82 drives the top telescopic part of the oil phase sealing plate 32 to descend, and before the angle between the connecting plate 81 and the driven plate 82 is 180°, the bottom of the oil phase sealing plate 32 abuts against the inner bottom of the oil phase discharge pipe 31. As the rack 42 continues to descend and the connecting shaft 75 continues to rotate, the top of the oil phase sealing plate 32 slides toward the bottom, so that the oil phase sealing plate 32 as a whole squeezes the oil phase discharge pipe 31, so that the sealing effect is better. At the lowest point of this process when the rack 42 descends, the driven plate 82 drives the top of the oil phase sealing plate 32 to extend slightly, and there is an obtuse angle between the connecting plate 81 and the driven plate 82, and the hinge point is close to the rack 42.

[0062] This embodiment also provides a method for preparing cyhalofop-butyl emulsion in water, which mainly comprises the following steps:

[0063] S1, respectively putting the raw materials for preparing the water phase and the raw materials for preparing the oil phase into a raw material mixer 1;

[0064] S2, start the stirring mechanism 13;

[0065] S3, starting the driving mechanism 4 to lift the driving mechanism 4 to the top, thereby opening the water phase feeding assembly 2, and starting the magnetic stirrer 10 after the water phase has finished flowing out;

[0066] S4, starting the driving mechanism 4 to make it descend to the lowest end, thereby opening the oil phase feeding assembly 3;

[0067] S5, after the oil phase is discharged, the driving mechanism 4 is started to complete the lifting again, so that the water phase discharge component 2 and the oil phase discharge component 3 are both closed;

[0068] S6, sending the crude emulsion stirred by the magnetic stirrer 10 into a high shear emulsifier for shearing.

[0069] Compared with the prior art, the present application can reduce the possibility of errors in the order of adding the water phase and the oil phase that may occur when operating multiple buttons.

It cannot be determined that the specific implementation of the present invention is limited to these descriptions.
