Description

Technical Field

[0001] The invention relates to the technical field of stirring and mixing, and in particular to a preparation device and method for a compound acaricide composition containing fenbutatin. Background Art

[0002] When preparing a compound acaricide composition containing fenbutatin, the components need to be added gradually in the order required by the formula, usually adding the matrix or solvent first, and then adding the active ingredients and other additives one by one, and then stirring and mixing.

[0003] Existing acaricidal composition preparation devices usually adopt a single stirring method, that is, stirring by a stirring rod. However, in actual operation, if the components are not fully dispersed during the stirring process, especially when the components with higher density sink, the dispersion treatment is not carried out in time, stratification or precipitation may occur, especially for components with different densities or limited solubility, which may cause the pH value of the solution to be different at different depths of the stirring barrel. The stratification or precipitation phenomenon will lead to a decrease in the quality of the final product and affect the acaricidal effect. For example, stratification will lead to too high or too low concentrations of certain components, and the acaricidal effect will be weakened in some areas after spraying, affecting the overall prevention and control effect.

[0004] In order to avoid the above problems, the present invention provides a device and method for preparing a compound acaricide composition containing fenbutatin. Summary of the invention

[0005] In order to overcome the disadvantages of a single stirring method, which may cause stratification or precipitation, the present invention provides a preparation device and method for a composite acaricide composition containing fenbutatin.

[0006] A preparation device of a compound acaricide composition containing fenbutatin comprises a stirring barrel, wherein the stirring barrel is fixedly connected with cylinders symmetrically distributed along the stirring barrel, a connecting frame is fixedly connected between the telescopic ends of the symmetrically distributed cylinders, the connecting frame is fixedly connected with a bracket, a stirring frame is rotatably connected in the middle of the connecting frame, a paddle of the stirring frame is arranged at the lower part, the bracket is spline-connected with a first sliding rod, the first sliding rod is movably connected with the stirring frame, two upper and lower pH sensors are fixedly connected to one side of the first sliding rod close to the paddle, one of the pH sensors is located outside the paddle of the stirring frame, and the other pH sensor is located inside the paddle of the stirring frame, the bracket is provided with a stirring component for driving the stirring frame to rotate, and the bracket is provided with a switching component for switching the two upper and lower pH sensors.

[0007] Furthermore, the stirring assembly includes a motor, the motor is fixedly connected to the bracket, the output shaft of the motor and the side of the stirring frame away from the blades are both fixedly connected with gears, and the two gears are meshed with each other.

[0008] Furthermore, the switching assembly includes fixed blocks symmetrically distributed along the bracket, the fixed blocks are fixedly connected to the bracket, the second sliding rod moves downward to contact the top of the mixing barrel, the fixed block is rotatably connected to a rocker rod, and one end of the rocker rod close to the first sliding rod is movably connected to the first sliding rod through a movable groove.

[0009] Furthermore, the switching assembly also includes a second sliding rod, the second sliding rod is slidably connected to the connecting frame, and the second sliding rod is movably connected to an end of the swing rod away from the first sliding rod.

[0010] Furthermore, the switching assembly also includes a fixing rod, which is fixedly connected to the mixing barrel and contacts the top of the second sliding rod.

[0011] Furthermore, it also includes a rotating ring, which is rotatably connected to one end of the first sliding rod close to the pH sensor, and a baffle is slidably connected to one side of the stirring frame close to the pH sensor along the up and down directions, and the baffle is fixedly connected to a cleaning block for cleaning the pH sensor, and the cleaning block is fixedly connected to the rotating ring.

[0012] Furthermore, it also includes heating plates evenly distributed circumferentially, and the heating plates are fixedly connected to the inner wall of the mixing barrel.

[0013] Furthermore, an observation plate is included, which is fixed to the mixing barrel and is used to visually observe the internal mixing conditions.

[0014] Furthermore, the observation plate is marked with scale lines evenly distributed longitudinally for measuring the amount of material added.

[0015] A method for preparing a compound acaricide composition containing fenbutatin comprises the following steps: S1, adding fenbutatin as a matrix solvent into the stirring barrel, and then adding active ingredients and other additives one by one; S2, starting the cylinder and the motor, so that the stirring frame continuously moves up and down and continuously stirs; S3, when the pH sensor moves to the layered area with high density, the pH sensor sends an electrical signal, the control module receives the electrical signal, and controls the telescopic rod of the cylinder to pause, so that the stirring frame stays in the layered area with high density for centralized stirring; S4, turning off the cylinder and the motor.

[0016] Beneficial effects: The present invention realizes the effect of continuous up-and-down movement and continuous stirring of the stirring frame by starting the cylinder and the motor, thereby ensuring that the mixed liquid can be fully mixed at all levels and improving the uniformity of the mixed liquid.

[0017] When stratification occurs, the pH sensor sends an electrical signal, the control module receives the electrical signal, and controls the telescopic rod of the cylinder to pause, so that the stirring frame stays in the stratified area with higher density for centralized stirring. By automatically detecting the stratified area and performing targeted stirring, the stratification phenomenon can be quickly eliminated and the mixing effect can be improved.

[0018] The present invention drives the first sliding rod to slide relative to the stirring frame by swinging the swing rod, so that the pH sensors on the upper and lower sides are automatically switched, ensuring that the paddles of the stirring frame always contact the mixed liquid in the denser area before the pH sensor in different moving directions, so as to ensure that the paddles of the stirring frame are located in the denser stratified area instead of outside the area, thereby ensuring the effect of eliminating the stratification phenomenon.

[0019] The cleaning block of the present invention can move up and down synchronously with the pH sensor. When the stirring frame rotates, the stirring frame drives the cleaning block to rotate through the baffle, thereby ensuring that during the stirring process, the cleaning block can always clean the two pH sensors at the same time, avoiding contamination or covering of the pH sensor surface, resulting in inaccurate measurement, and the silicone material can provide a certain friction force, which is helpful to remove attachments without causing damage to the pH sensor.

[0020] When preparing the compound acaricide composition containing fenbutatin, appropriate heating can improve the solubility of each component, accelerate the mixing process, reduce viscosity and improve stirring efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Embodiment 1: A preparation device for a composite acaricide composition containing fenbutatin, combined with the attached Figure 1 To Attachment Figure 3 , including a mixing barrel 101, the mixing barrel 101 is fixedly connected to cylinders 102 symmetrically distributed along the mixing barrel 101, a connecting frame 103 is fixedly connected between the telescopic ends of the symmetrically distributed cylinders 102, a bracket 104 is fixedly connected to the top of the connecting frame 103, a motor 105 is fixedly connected to the right part of the bracket 104, a stirring frame 107 is rotatably connected to the middle of the connecting frame 103, a paddle of the stirring frame 107 is arranged at the bottom, and a gear 106 is fixedly connected to the output shaft of the motor 105 and the upper part of the stirring frame 107, and the two gears 106 are meshed with each other The bracket 104 is spline-connected with a first sliding rod 108 along the up and down directions. The first sliding rod 108 is movably connected to the stirring frame 107, so that the first sliding rod 108 can slide on the stirring frame 107, and the stirring frame 107 can rotate on the first sliding rod 108. Two upper and lower pH sensors 109 are fixedly connected to one side of the first sliding rod 108 close to the paddle. When one of the pH sensors 109 is located outside the paddle of the stirring frame 107, the other pH sensor 109 is located inside the paddle of the stirring frame 107.

[0032] Combined with Figure 4 and attached Figure 5, and also includes a fixed block 201 symmetrically distributed along the front and back of the bracket 104, the fixed block 201 is fixedly connected to the bracket 104, the connecting frame 103 is slidably connected to the second sliding rod 202 along the up and down direction, the second sliding rod 202 moves downward and contacts the top of the mixing barrel 101, and the side of the mixing barrel 101 close to the second sliding rod 202 is fixedly connected to the fixed rod 203, the upper part of the fixed rod 203 contacts the top of the second sliding rod 202, the fixed block 201 is rotatably connected to the swing rod 204, the end of the swing rod 204 close to the first sliding rod 108 is movably connected to the first sliding rod 108 through a movable groove, and the end of the swing rod 204 away from the first sliding rod 108 is movably connected to the second sliding rod 202.

[0033] First, fenbutatin is added into the stirring barrel 101 as a matrix solvent, and then active ingredients and other additives are added one by one. Next, the cylinder 102 and the motor 105 are started, and the telescopic rod of the cylinder 102 slowly reciprocates and retracts, thereby driving the connecting frame 103, the bracket 104, the motor 105, the gear 106, the stirring frame 107, the first sliding rod 108, the pH sensor 109, the fixed block 201, the second sliding rod 202 and the swing rod 204 to move up and down as a whole. At the same time, the output shaft of the motor 105 drives the stirring frame 107 to rotate through the gear 106, so that the stirring frame 107 can continuously move up and down and continuously stir, ensuring that the mixed liquid can be fully mixed at all levels and improving the uniformity of the mixed liquid.

[0034] In the above process, the pH sensor 109 monitors the pH value of the mixed liquid in real time. If stratification occurs, when the pH sensor 109 moves to a stratified area with higher density, the pH sensor 109 sends an electrical signal, the control module receives the electrical signal, and controls the telescopic rod of the cylinder 102 to pause, so that the stirring frame 107 stays in the stratified area with higher density for centralized stirring. By automatically detecting the stratified area and performing targeted stirring, the stratification phenomenon can be quickly eliminated and the mixing effect can be improved.

[0035] In the above process, when the stirring frame 107 moves from top to bottom, the upper pH sensor 109 is exposed outside the blades of the stirring frame 107. During the downward movement, when the upper pH sensor 109 moves downward to the boundary of the stratification zone with higher density, the cylinder 102 pauses. At this time, the blades of the stirring frame 107 are located below the boundary of the stratification zone with higher density, which ensures that the blades of the stirring frame 107 are located in the stratification zone with higher density.

[0036] When the second sliding rod 202 moves downward until it contacts the top of the mixing barrel 101, the second sliding rod 202 stops moving downward, while the connecting frame 103, the bracket 104 and other components continue to move downward, that is, the second sliding rod 202 slides relative to the connecting frame 103, so that the swing rod 204 swings around the fixed block 201, and the left part of the swing rod 204 swings downward to push the first sliding rod 108 to slide downward relative to the mixing frame 107, thereby switching the pH sensors 109 on the upper and lower sides.

[0037] After the switch, when the stirring rack 107 moves from bottom to top, the lower pH sensor 109 is exposed outside the paddles of the stirring rack 107. During the upward movement, when the lower pH sensor 109 moves upward to the boundary of the stratified area with higher density, the cylinder 102 pauses. At this time, the paddles of the stirring rack 107 are located above the boundary of the stratified area with higher density, and the paddles of the stirring rack 107 are also ensured to be located in the stratified area with higher density. In this way, it is ensured that under different moving directions, the paddles of the stirring rack 107 always contact the mixed liquid in the denser area before the pH sensor 109, so as to ensure that the paddles of the stirring rack 107 are located in the stratified area with higher density, rather than outside the area, thereby ensuring the effect of eliminating the stratification phenomenon.

[0038] When the second sliding rod 202 moves upward until it contacts the upper part of the fixed rod 203, the second sliding rod 202 stops moving upward, while the connecting frame 103, the bracket 104 and other components continue to move upward, that is, the second sliding rod 202 slides relative to the connecting frame 103, so that the swing rod 204 swings in the opposite direction around the fixed block 201, and the left part of the swing rod 204 swings upward to push the first sliding rod 108 to slide upward relative to the stirring frame 107, thereby switching the pH sensors 109 on the upper and lower sides again.

[0039] Embodiment 2: Based on embodiment 1, Figure 6 and attached Figure 7 , and also includes a rotating ring 301, which is rotatably connected to the bottom end of the first sliding rod 108, and the lower part of the stirring frame 107 is slidably connected to a baffle 302 along the up and down directions. A cleaning block 303 for cleaning the pH sensor 109 is fixedly connected to the side of the baffle 302 close to the rotating ring 301, and the cleaning block 303 is set to be made of rubber, and the cleaning block 303 is fixedly connected to the rotating ring 301.

[0040] When the first sliding rod 108 drives the pH sensor 109 to move upward or downward relative to the stirring frame 107, the first sliding rod 108 drives the rotating ring 301 to move upward or downward synchronously, thereby driving the cleaning block 303 to move upward or downward synchronously, and then driving the baffle 302 to move upward or downward synchronously along the stirring frame 107. In this way, the cleaning block 303 can move up and down synchronously with the pH sensor 109. When the stirring frame 107 rotates, the stirring frame 107 drives the cleaning block 303 to rotate through the baffle 302, ensuring that during the stirring process, the cleaning block 303 can always clean the two pH sensors 109 at the same time, avoiding the surface of the pH sensor 109 from being contaminated or covered, resulting in inaccurate measurement, and the rubber material can provide a certain friction, which is helpful to remove attachments and will not cause damage to the pH sensor 109.

[0041] Combined with Figure 8 , and also includes a heating plate 401 evenly distributed in the circumferential direction, the heating plate 401 is fixed to the inner wall of the stirring barrel 101. When preparing the compound acaricide composition containing fenbutatin, moderate heating can improve the solubility of each component, accelerate the mixing process, reduce the viscosity, and improve the stirring efficiency.

[0042] Combined with Figure 8 , and also includes an observation plate 501, which is fixed to the mixing barrel 101 and is used to visually observe the internal mixing situation. The observation plate 501 is marked with longitudinally evenly distributed scale lines 502 for measuring the amount of material added.

[0043] The above is a detailed introduction to the present application. Specific examples are used in this article to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method of the present application and its core idea. At the same time, for general technical personnel in this field, according to the idea of ​​the present application, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
