Description

Technical Field

[0001] This invention relates to the field of herbicide preparation technology, specifically to an apparatus and method for preparing diuron wettable powder with high suspension rate. Background Technology

[0002] Diuron is a urea-substituted herbicide with systemic and some contact action. After absorption by plant roots or leaves, it inhibits photosynthesis, causing chlorosis and discoloration of leaf tips and edges. At low doses, diuron can selectively control weeds through position and time differences. At high doses, it becomes a non-selective herbicide. It is mainly used to control annual grass weeds in crops such as cotton, soybeans, tomatoes, tobacco, strawberries, grapes, orchards, and rubber plantations. To improve the herbicidal effect and environmental protection, diuron is generally prepared as a wettable powder suspension. This formulation offers advantages such as good absorption by crops, uniform mixing and dispersion with water in any proportion, minimal impact from water quality, ease of use, and low environmental pollution.

[0003] In preparing diuron wettable powder suspensions, to improve the suspension rate, the current common practice is to add diuron wettable powder, thickener, dispersant, and water into a grinder for grinding and mixing. However, this method of preparing diuron wettable powder suspensions solely through grinding has the following problems:

[0004] The preparation method is simple. Although the diuron wettable powder suspension can be directly mixed and exported after preparation, the prepared diuron wettable powder suspension is prone to large suspension rate errors, making it difficult to achieve a consistently high suspension rate and reducing the quality of the diuron wettable powder suspension.

[0005] In summary, there is a need for a stable apparatus for preparing diuron wettable powder suspension with a high suspension rate. Summary of the Invention

[0021] A method for preparing diuron wettable powder with high suspension rate, the preparation method comprising the following steps:

[0022] S1, Mixing and grinding;

[0023] Add diuron wettable powder into the grinder, add thickener, dispersant and water into the grinder, and mix and grind to obtain diuron wettable powder suspension;

[0024] The grinder introduces diuron wettable powder suspension into the first and second test chambers respectively, and the diuron wettable powder suspension is then introduced into the test bottle in a uniformly mixed state.

[0025] The transmittance of standard diuron wettable powder suspension in a uniformly mixed state is P01-P02, and the complete settling time is t0.

[0026] S2, Suspension rate detection;

[0027] S2.1 Settlement detection;

[0028] Illuminate the test bottle with a lamp strip to obtain the complete settling time t1 of the diuron wettable powder suspension. Compare the settling time t1 with t0 and adjust the amount of thickener added to ensure a high suspension rate.

[0029] If t1 > t0, reduce the amount of thickener added;

[0030] If t1 < t0, increase the amount of thickener added;

[0031] S2.2, Clumping detection;

[0032] After the diuron wettable powder suspension in the test bottle has completely settled, shake the test bottle to ensure that the diuron wettable powder suspension is evenly distributed inside the test bottle.

[0033] The test bottle was illuminated by a light strip, and the transmittance P31 (upper part), P32 (middle part), and P33 (lower part) of the test bottle were obtained. The transmittances P31, P32, and P33 were then compared.

[0034] No, they are all within the range of P01-P02;

[0035] Yes, reduce the amount of dispersant added;

[0036] No, increase the amount of dispersant added.

[0037] Furthermore, in step S2.1, light passes through the test bottle and the diuron wettable powder suspension and is projected onto the first, second, and third photosensitive sensors. The light transmittance P11 at the top, P12 at the middle, and P13 at the bottom of the test bottle are obtained respectively. After time t1, the light transmittance inside the test bottle tends to stabilize, and the light transmittance P21 at the top, P22 at the middle, and P23 at the bottom of the test bottle are obtained respectively. Then, t1 is the time for the diuron wettable powder suspension to completely settle.

[0038] Furthermore, in step S2.2, the temperature of the first limiting plate and the second limiting plate inside the first testing box is adjusted to 0±0.1℃, and the temperature of the first limiting plate and the second limiting plate inside the second testing box is adjusted to 54±2℃, so that the diuron wettable powder suspension in the test bottle inside the first testing box and the diuron wettable powder suspension in the test bottle inside the second testing box are completely settled.

[0039] This invention provides an apparatus and method for preparing diuron wettable powder with high suspension rate. Compared with the prior art, it has the following advantages:

[0040] 1. By introducing the well-ground and mixed diuron wettable powder suspension into the test bottle, and then using the receiving component and the light transmission component to detect the settling speed of the diuron wettable powder suspension, the viscosity of the diuron wettable powder suspension can be determined. The amount of thickener added is then adjusted to ensure the viscosity of the diuron wettable powder suspension, so that the mixed diuron wettable powder suspension has a higher suspension rate.

[0041] 2. After the diuron wettable powder suspension has completely settled, the second drive component controls the shaking of the diuron wettable powder suspension inside the test bottle to achieve a mixed state. Then, the light transmittance of the diuron wettable powder suspension is detected by the receiving component and the light transmitting component, thereby determining the degree of agglomeration of the diuron wettable powder suspension. The amount of dispersant added is then adjusted to ensure the dispersion of the diuron wettable powder suspension, so that the mixed diuron wettable powder suspension has a higher suspension rate.

[0042] 3. During the precipitation of diuron wettable powder suspension, the first and second limiting plates inside the first detection chamber cool the diuron wettable powder suspension to simulate the precipitation and agglomeration of diuron wettable powder suspension in a low-temperature environment. The first and second limiting plates inside the second detection chamber heat the diuron wettable powder suspension to simulate the precipitation and agglomeration of diuron wettable powder suspension in a high-temperature environment. This allows for the detection and adjustment of diuron wettable powder suspension to maintain a high suspension rate under both low-temperature and high-temperature environments.

Detailed Implementation

[0053] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are described clearly and completely. 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.

[0054] Example 1

[0055] To address the technical problems in the background section, the following apparatus and method for preparing diuron wettable powder with high suspension rate are provided:

[0056] Combination Figures 1-8As shown, the high suspension rate preparation device for diuron wettable powder provided by the present invention includes a grinder 1. A first reagent tank 11 and a second reagent tank 12 are provided on the top surface of the grinder 1. A first control valve 111 is connected between the first reagent tank 11 and the grinder 1. A second control valve 121 is connected between the second reagent tank 12 and the grinder 1. A discharge pipe 13 is connected to the side wall of the grinder 1. A third control valve 2 is connected to the end of the discharge pipe 13 away from the grinder 1. A first conduit 21 is connected to one side of the third control valve 2 and a second conduit 22 is connected to the other side. A first detection box 3 is connected to one end of the first conduit 21 and a second detection box 4 is connected to one end of the second conduit 22. The first detection box 3 and the second detection box 4 have the same structure and both are provided with a detection mechanism 6. A door 31 is provided on one side of the first detection box 3. A touch screen 311 is fixed on the outer wall of the door 31.

[0057] The detection mechanism 6 includes a receiving component 61, a light-transmitting component 62, and a second driving component 64. One side of the receiving component 61 is rotatably connected to the inner wall of the first detection box 3. The second driving component 64 is disposed on the bottom surface inside the first detection box 3. The light-transmitting component 62 is disposed inside the receiving component 61, and a test bottle 5 is disposed inside the light-transmitting component 62. The light emitted by the light-transmitting component 62 passes through the test bottle 5 and is projected onto the receiving component 61 to detect the light transmittance of the suspension in the test bottle 5. The receiving component 61 is driven to rotate by the second driving component 64 to make the suspension in the test bottle 5 shake evenly. One end of the first conduit 21 passes through the inside of the first detection box 3 and is connected to an inlet hose 211. One end of the inlet hose 211 is connected to the inside of the receiving component 61.

[0058] The receiving component 61 includes a back plate 611, a top plate 612, and a bottom plate 613. One side of the back plate 611 is rotatably connected to the inner wall of the first detection box 3. The top plate 612 is vertically fixed to the top surface of the back plate 611, and the bottom plate 613 is vertically fixed to the bottom surface. The light-transmitting component 62 is fixed to the top surface of the bottom plate 613, and the bottom surface of the bottom plate 613 is fixed with an arc-shaped toothed plate 6131. ​​The second driving component 64 includes a second motor 641 and a third gear 642. The second motor 641 is fixed to the bottom surface inside the first detection box 3, and the rotating end of the second motor 641 is connected to the third gear 642. The third gear 642 is meshed with the bottom surface of the arc-shaped toothed plate 6131.

[0059] By introducing the well-ground and mixed diuron wettable powder suspension into the test bottle 5, and then using the receiving component 61 and the light-transmitting component 62 to detect the settling speed of the diuron wettable powder suspension, the viscosity of the diuron wettable powder suspension can be determined. The amount of thickener added is then adjusted to ensure the viscosity of the diuron wettable powder suspension, so that the mixed diuron wettable powder suspension has a higher suspension rate.

[0060] After the diuron wettable powder suspension has completely settled, the second drive component 64 controls the shaking of the diuron wettable powder suspension inside the test bottle 5 to mix it. Then, the light transmittance of the diuron wettable powder suspension is detected by the receiving component 61 and the light transmitting component 62 to determine the degree of agglomeration of the diuron wettable powder suspension. The amount of dispersant added is then adjusted to ensure the dispersion of the diuron wettable powder suspension, so that the mixed diuron wettable powder suspension has a higher suspension rate.

[0061] Because after the diuron wettable powder suspension settles, some components will descend, resulting in increased light transmittance at the top and decreased light transmittance at the bottom;

[0062] Even when the diuron wettable powder suspension is shaken and settled without clumping, the light transmittance is not affected, and thus the suspension rate is not affected, so it can still meet the usage requirements.

[0063] In the case of clumping, after shaking and settling the diuron wettable powder suspension, the clumps gather together, causing some areas to have increased light transmittance and some areas to have decreased light transmittance, and the distribution is uneven. Therefore, the distribution of light transmittance can be used to determine whether there is clumping.

[0064] Therefore, by thoroughly shaking the mixture and testing the transmittance, the clumping situation can be determined. Then, by increasing or decreasing the dispersant, clumping can be avoided and the dispersion can be guaranteed, thereby ensuring that the diuron wettable powder suspension has a high suspension rate.

[0065] In this embodiment, the light-transmitting component 62 includes a first limiting plate 621, a light strip 622, and a second limiting plate 623. The first limiting plate 621 and the second limiting plate 623 are both arc structures and are mirror images of each other. There are two gaps between the first limiting plate 621 and the second limiting plate 623. The light strip 622 is fixed inside the gap on the side away from the back plate 611.

[0066] The back plate 611 has a first photosensitive sensor 6111, a second photosensitive sensor 6112, and a third photosensitive sensor 6113 fixedly in a vertical direction from top to bottom. The light from the light strip 622 passes through the gap between the first limiting plate 621 and the second limiting plate 623 and is projected onto the first photosensitive sensor 6111, the second photosensitive sensor 6112, and the third photosensitive sensor 6113.

[0067] By passing the light emitted by the light strip 622 through the test bottle 5 and illuminating the first photosensitive sensor 6111, the second photosensitive sensor 6112, and the third photosensitive sensor 6113, the light transmittance of the upper, middle, and lower parts of the test bottle 5 can be obtained, thereby improving the accuracy of light transmittance detection for diuron wettable powder suspension.

[0068] In this embodiment, the top of the test bottle 5 is connected to a bottle tube 51, the outer wall of the bottle tube 51 is fitted with a toothed ring 512, the bottom of the test bottle 5 is fixed with a base 52, and the detection mechanism 6 also includes a first driving component 63, which is disposed inside the top plate 612.

[0069] The first drive assembly 63 includes a first gear 631, a second gear 632, and a first motor 633. The first gear 631 and the second gear 632 are rotatably connected to the bottom surface of the top plate 612. The first motor 633 is disposed on the top surface of the top plate 612. The rotating bottom end of the first motor 633 is connected to the second gear 632. The gear ring 512 is meshed between the first gear 631 and the second gear 632.

[0070] When the test bottle 5 is shaken using the second drive component 64, the first drive component 63 drives the test bottle 5 to rotate, which facilitates the mixing of diuron wettable powder suspension at multiple angles, thereby improving the efficiency and completeness of adjusting the diuron wettable powder suspension to a mixed state.

[0071] Example 2

[0072] like Figures 2-7 As shown, based on the above embodiments, this embodiment further provides the following:

[0073] Because there may be clumping after the diuron wettable powder suspension settles, it is necessary to shake the diuron wettable powder suspension in the test bottle 5 thoroughly. However, even if the test bottle 5 is shaken along the arc direction by only using the second drive component 64, there may still be uneven shaking. To solve the above problem, the following structure is adopted.

[0074] The toothed ring 512 is slidably sleeved on the outer wall of the bottle tube 51, and the outer wall of the bottle tube 51 is fixed with a limiting block 511. A slot is provided on the inner side of the toothed ring 512, and the slot is used to slide and engage the limiting block 511.

[0075] The limiting block 511 restricts the rotation direction of the toothed ring 512, so that the bottle tube 51 and the toothed ring 512 rotate together. The toothed ring 512 can slide relative to the bottle tube 51 in the vertical direction, so that the bottle 5 can move in the vertical direction.

[0076] In this embodiment, the bottom surface of the base 52 is provided with an annular groove 521, and a protrusion 522 is fixed inside the groove 521. The protrusion 522 has an arc-shaped structure. A support column 6132 is fixed on the top surface of the base plate 613. A ball bearing 6133 is embedded in the top surface of the support column 6132. The top end of the support column 6132 is slidably connected to the inside of the groove 521. The base 52 has a rising state and a falling state by rotating on the support column 6132.

[0077] In the rising state: the ball 6133 rolls and fits against the bottom surface of the protrusion 522;

[0078] In the descending state: the ball bearing 6133 rolls and adheres to the top surface of the groove 521;

[0079] When the test bottle 5 is rotated to adjust the diuron wettable powder suspension to a mixed state, the ball bearing 6133 rolls and switches on the groove 521 and the protrusion 522, causing the base 52 to drive the test bottle 5 to shake up and down. This can be coordinated with the flipping and shaking of the receiving component 61, further improving the efficiency and completeness of adjusting the diuron wettable powder suspension to a mixed state.

[0080] In this embodiment, a second insertion tube 6121 is connected through the top plate 612. The top end of the second insertion tube 6121 is connected to an inlet hose 211, and the bottom end is slidably inserted into the bottle tube 51. A first insertion tube 513 is connected to the bottom surface of the test bottle 5. The bottom end of the first insertion tube 513 passes through the base 52 and the bottom plate 613 and is connected to a drain hose 53. One end of the drain hose 53 is connected through to the outside of the first detection box 3.

[0081] The second insertion tube 6121, the first insertion tube 513, the inlet hose 211, and the outlet hose 53 not only form a flow channel for the flow detection of diuron wettable powder suspension, but also ensure the stability of the test bottle 5 when it shakes up and down by the fact that the second insertion tube 6121 slides inside the bottle tube 51 and the first insertion tube 513 slides inside the base plate 613. The use of flexible inlet hose 211 and outlet hose 53 ensures the flexibility when the test bottle 5 is shaken.

[0082] Example 3

[0083] like Figures 1-8 As shown, based on the above embodiments, this embodiment further provides the following:

[0084] Because diuron wettable powder suspension will precipitate after storage, and the temperature in the storage environment will have a certain impact on the precipitation, it is also necessary to ensure that diuron wettable powder suspension can still have a high suspension rate when shaken and used under different storage environment temperatures. To solve the above problems, the following structure is adopted.

[0085] The first limiting plate 621 and the second limiting plate 623 inside the first detection box 3 are both equipped with refrigeration components, and the first limiting plate 621 and the second limiting plate 623 inside the second detection box 4 are both equipped with heating components.

[0086] During the precipitation of diuron wettable powder suspension, the first limiting plate 621 and the second limiting plate 623 inside the first detection chamber 3 cool the diuron wettable powder suspension to simulate the precipitation and agglomeration of diuron wettable powder suspension in a low-temperature environment. The first limiting plate 621 and the second limiting plate 623 inside the second detection chamber 4 heat the diuron wettable powder suspension to simulate the precipitation and agglomeration of diuron wettable powder suspension in a high-temperature environment. This allows for the detection and adjustment of diuron wettable powder suspension that can maintain a high suspension rate under both low-temperature and high-temperature environments.

[0087] Example 4

[0088] like Figures 1-8 As shown, based on the above embodiments, this embodiment further provides the following:

[0089] A method for preparing diuron wettable powder with high suspension rate, the preparation method comprising the following steps:

[0090] S1, Mixing and grinding;

[0091] Add diuron wettable powder into the grinder 1, add thickener, dispersant and water into the grinder 1, and mix and grind to obtain diuron wettable powder suspension;

[0092] The above steps are as follows: the first control valve 111 and the second control valve 121, which are electrically connected, are controlled by the touch screen 311. The first control valve 111 is opened to add the thickener in the first medicine tank 11 into the grinder 1. The second control valve 121 is opened to add the dispersant in the second medicine tank 12 into the grinder 1.

[0093] The grinder 1 introduces diuron wettable powder suspension into the first test chamber 3 and the second test chamber 4 respectively, and the diuron wettable powder suspension is then introduced into the test bottle 5 in a uniformly mixed state.

[0094] The specific steps are as follows: the touch screen 311 controls the third control valve 2 to open, and introduces the ground and mixed diuron wettable powder suspension in the grinder 1 into the first conduit 21 and the second conduit 22, and then into the first detection box 3 and the second detection box 4 respectively.

[0095] In the first test chamber 3 and the second test chamber 4, the diuron wettable powder suspension enters the test bottle 5 through the inlet hose 211 and the first insertion tube 513, until the diuron wettable powder suspension is filled to the bottom of the bottle tube 51. At this time, the diuron wettable powder suspension is in a uniformly mixed state.

[0096] The transmittance of standard diuron wettable powder suspension in a uniformly mixed state is P01-P02, and the complete settling time is t0.

[0097] S2, Suspension rate detection;

[0098] S2.1 Settlement detection;

[0099] The test bottle 5 was irradiated with lamp strip 622 to obtain the complete settling time t1 of diuron wettable powder suspension. The settling time t1 and t0 were compared, and the amount of thickener added was adjusted to ensure a high suspension rate.

[0100] The specific steps are as follows: light passes through the test bottle 5 and the diuron wettable powder suspension and is projected onto the first photosensitive sensor 6111, the second photosensitive sensor 6112 and the third photosensitive sensor 6113. The light transmittance P11 of the upper part, P12 of the middle part and P13 of the lower part of the test bottle 5 are obtained respectively. After time t1, the light transmittance inside the test bottle 5 tends to stabilize, and the light transmittance P21 of the upper part, P22 of the middle part and P23 of the lower part of the test bottle 5 are obtained respectively. Then t1 is the time for the diuron wettable powder suspension to completely settle.

[0101] If t1 > t0, the touch screen 311 controls the reduction of the opening time of the first control valve 111 and the reduction of the amount of thickener added to the first medicine tank 11;

[0102] If t1 < t0, the touch screen 311 controls the opening time of the first control valve 111 to increase the amount of thickener added to the first medicine tank 11;

[0103] S2.2, Clumping detection;

[0104] The cooling components inside the first limiting plate 621 and the second limiting plate 623 inside the first testing box 3 use cold water pipes, and the temperature of the first limiting plate 621 and the second limiting plate 623 inside the first testing box 3 is adjusted to 0℃. The heating components inside the first limiting plate 621 and the second limiting plate 623 inside the second testing box 4 use hot water pipes.

[0105] The temperature of the first limiting plate 621 and the second limiting plate 623 inside the second test box 4 is adjusted to 54°C, and then the diuron wettable powder suspension in the test bottle 5 inside the first test box 3 and the diuron wettable powder suspension in the test bottle 5 inside the second test box 4 are completely settled.

[0106] After the diuron wettable powder suspension in test bottle 5 has completely settled, shake test bottle 5 to make the diuron wettable powder suspension evenly distributed inside test bottle 5.

[0107] The specific steps described above are as follows: The second motor 641 drives the third gear 642 to rotate reciprocally. The third gear 642 meshes with the arc-shaped toothed plate 6131 on the bottom surface of the base plate 613, causing the back plate 611 to rotate inside the first detection box 3. The test bottle 5 swings back and forth. At the same time, the first motor 633 drives the second gear 632 to rotate, which, in conjunction with the first gear 631, drives the toothed ring 512 to rotate. Under the restriction of the limit block 511, the toothed ring 512 drives the bottle tube 51 to rotate, causing the test bottle 5 to drive the base 52 to rotate on the support column 6132. As the base 52 rotates, the ball bearings 6133 on the support column 6132 roll against the slide groove 521 or the protrusion 522 and repeatedly switch rolling, causing the base 52 to drive the test bottle 5 to swing up and down.

[0108] The light strip 622 illuminates the test bottle 5, and the light transmittance P31 of the upper part, P32 of the middle part and P33 of the lower part of the test bottle 5 are obtained respectively. The light transmittance P31, P32 and P33 are compared to see if they are all within the range of P01-P02.

[0109] Yes, the touch screen 311 controls the reduction of the opening time of the second control valve 121, thereby reducing the amount of dispersant added to the second reagent tank 12;

[0110] No, the touch screen 311 controls the opening time of the second control valve 121 and increases the amount of dispersant added to the second medicine tank 12.
