Description

Technical Field

[0001] The invention relates to the technical field of thiophanate-methyl, and in particular to a device and method for preparing a high-time wetting type thiophanate-methyl wettable powder. Background Art

[0002] Thiophanate-methyl is a fungicide that appears as a white, odorless solid powder. It is primarily used to control fungal diseases in various crops, such as apples, pears, grapes, strawberries, peaches, and other fruit trees, as well as wheat, rice, sugarcane, and tea. It kills fungi and prevents disease by blocking the growth of fungal cell membranes. Compared to other fungicides, thiophanate-methyl is highly effective, broad-spectrum, low-toxic, and stable. It not only kills pathogens, but also causes minimal damage to crops and poses few environmental risks.

[0003] Since thiophanate-methyl is almost insoluble in water and stable to acids and alkalis, and has poor solubility, thiophanate-methyl is generally prepared as a wettable powder. When preparing thiophanate-methyl wettable powder, it is usually necessary to use a preparation device to mix various excipients with thiophanate-methyl.

[0004] Since a large number of auxiliary materials are required when preparing thiophanate-methyl wettable powder, in order to fully mix thiophanate-methyl with a variety of auxiliary materials and ensure that the auxiliary materials can fully exert their effects, thiophanate-methyl needs to be mixed multiple times when preparing thiophanate-methyl wettable powder.

[0005] However, when the preparation device is actually used, it is found that since the mixing of methyl thiophanate usually requires multiple steps, the ratio of methyl thiophanate mixed is likely to be poor during the process of continuous delivery of methyl thiophanate and addition of auxiliary materials for mixing, and the mixing of methyl thiophanate and various auxiliary materials is not sufficient. After the methyl thiophanate wettable powder is mixed and prepared, the methyl thiophanate wettable powder is likely to have uneven particles or even clumps, which is not conducive to the long-term wetting of the methyl thiophanate wettable powder and is not convenient for the prepared methyl thiophanate wettable powder to fully exert the characteristics of methyl thiophanate when used.

[0006] In summary, there is a need for a device and method for preparing a high-wetting-time thiophanate-methyl wettable powder. Summary of the Invention

[0018] The working method of the high-time wetting type thiophanate-methyl wettable powder preparation device comprises the following steps:

[0019] S1. Adding a flow agent: feeding methyl thiophanate solid powder and a flow agent into a discharge basin through a first feeding pipe and a second feeding pipe in proportion. At this time, a second motor controls the top plate to drive the discharge basin to rotate together. When the discharge basin rotates, the connecting rod and the stirring plate inside the discharge basin stir the methyl thiophanate solid powder and the flow agent, so that the methyl thiophanate solid powder and the flow agent are mixed together;

[0020] S2. Adding a wetting agent: The mixture of thiophanate-methyl solid powder and flow agent is continuously stirred by the inclined stirring plate and gathered in the middle of the lower material basin. The gathered mixture falls into the material guide pipe and then falls onto the inner bottom surface of the first cylinder. At this time, the third feeding pipe feeds the wetting agent into the interior of the first cylinder according to the proportion. Then, the wetting agent contacts and mixes with the mixture.

[0021] S3. Deep stirring: The guide pipe rotates along with the feed basin. The rotating guide pipe drives the mixing rod, the first mixing plate, the second mixing plate, and the support ring to rotate together. The rotating mixing rod, the first mixing plate, and the second mixing plate stir the wetting agent and the mixture, so that the wetting agent is evenly incorporated into the mixture of the methyl thiophanate solid powder and the flow agent. In this way, the mixture of the methyl thiophanate solid powder, the flow agent, and the wetting agent is fully stirred and mixed.

[0022] S4. Adding adsorbent: The spiral blades on the outside of the guide tube rotate with the guide tube, feeding the mixture containing the flow agent and the wetting agent to the top of the feed tube and dropping it into the gap between the feed tube and the first cylinder. At this time, the fourth feed tube feeds the adsorbent into the first cylinder to mix with the mixture. The falling mixture is mixed with the adsorbent. The mixing strips on the outside of the support ring rotate with the support ring and stir and mix the falling mixture and the adsorbent.

[0023] S5. Screening: The mixed thiophanate-methyl wettable powder will fall on the screen. The vibration motor will make the screen vibrate to assist the screen in screening the mixture. The rolling rod rotating on the side of the scraper plate can continuously roll the mixture by rotating to achieve the purpose of crushing and dispersing the mixture, so that the mixture can fully pass through the screen for screening.

[0024] The present invention provides a device and method for preparing a high-wetting-time thiophanate-methyl wettable powder. Compared with the prior art, it has the following advantages:

[0055] Example 3

[0056] like Figure 10As shown, based on the above embodiment, this embodiment further provides the following content:

[0057] In order to facilitate the preparation of a high-time-wetting type thiophanate-methyl wettable powder by the preparation device, the working method includes the following steps:

[0058] S1. Adding a flow agent: feeding methyl thiophanate solid powder and a flow agent into a discharge basin through a first feeding pipe and a second feeding pipe in proportion. At this time, a second motor controls the top plate to drive the discharge basin to rotate together. When the discharge basin rotates, the connecting rod and the stirring plate inside the discharge basin stir the methyl thiophanate solid powder and the flow agent, so that the methyl thiophanate solid powder and the flow agent are mixed together; exemplary flow agents include silicon dioxide, talc, etc., which are selected according to specific circumstances when selecting and mixing;

[0059] S2. Adding a wetting agent: The mixture of thiophanate-methyl solid powder and flow agent is continuously stirred by the inclined stirring plate and gathered in the middle of the lower material basin. The gathered mixture falls into the material guide pipe and then falls onto the inner bottom surface of the first cylinder. At this time, the third feeding pipe feeds the wetting agent into the first cylinder in proportion. Then, the wetting agent contacts and mixes with the mixture. Exemplary wetting agents include sodium lauryl sulfate, sodium dodecylbenzene sulfonate, etc.

[0060] S3, deep stirring: the guide tube rotates with the feed basin, and the rotating guide tube drives the mixing rod, the first mixing plate, the second mixing plate and the support ring to rotate together. The rotating mixing rod, the first mixing plate and the second mixing plate stir the wetting agent and the mixture, so that the wetting agent is evenly incorporated into the mixture of the methyl thiophanate solid powder and the flow agent. In this way, the mixture of the methyl thiophanate solid powder, the flow agent and the wetting agent is fully stirred and mixed, ensuring that the flow agent and the wetting agent can be evenly mixed with the methyl thiophanate solid powder to exert their characteristics in the methyl thiophanate solid powder;

[0061] S4. Adding adsorbent: The spiral blades on the outside of the guide tube will rotate with the guide tube, and send the mixture with the flow agent and the wetting agent to the top of the feed barrel and fall into the gap between the feed barrel and the first barrel. At this time, the fourth feed pipe sends the adsorbent into the first barrel to mix with the mixture. The falling mixture will be mixed with the adsorbent. At the same time, the mixing strips on the outside of the support ring will stir and mix the falling mixture with the adsorbent as they rotate with the support ring. Exemplary adsorbents include activated carbon and bentonite.

[0062] S5. Screening: The mixed thiophanate-methyl wettable powder will fall on the screen, and the vibration motor will make the screen vibrate, assisting the screen to screen the mixture, thereby achieving long-term wetting of the thiophanate-methyl wettable powder. The rolling rod rotating on the side of the scraper plate can continuously roll the mixture by rotating, thereby achieving the purpose of crushing and pressing the mixture, so that the mixture can fully pass through the screen for screening, ensuring that the size of the mixture particles is more uniform, thereby increasing the contact area of ​​the thiophanate-methyl wettable powder prepared by the device on the plant surface, and achieving the purpose of long-term wetting.

[0063] The working principle and use process of the present invention:

[0064] When using:

[0065] First, methyl thiophanate solid powder and flow agent are fed into the lower basin 21 through the first feeding pipe 12 and the second feeding pipe 13 in proportion. At this time, the second motor 24 controls the top plate 23 to drive the lower basin 21 to rotate together. When the lower basin 21 rotates, the connecting rod 25 and the stirring plate 26 inside the lower basin 21 will stir the methyl thiophanate solid powder and the flow agent, so that the methyl thiophanate solid powder and the flow agent are mixed together. At this time, the mixture will gather in the middle of the lower basin 21 under the action of continuous stirring of the inclined stirring plate 26, and the gathered mixture will fall into the guide pipe 32;

[0066] When re-mixing:

[0067] The mixed material that falls into the guide tube 32 will fall onto the inner bottom surface of the first cylinder 11. At this time, the third feeding tube 14 will feed the wetting agent into the first cylinder 11 in proportion. Then, the wetting agent will come into contact with the mixed material. Since the top end of the guide tube 32 is connected to the discharge basin 21, the guide tube 32 will rotate with the discharge basin 21. The rotating guide tube 32 will drive the mixing rod 41, the first mixing plate 42, the second mixing plate 43 and the supporting ring 35 to rotate together. The rotating mixing rod 41 and the first mixing plate 42 and the second mixing plate 43 will stir the wetting agent and the mixed material, so that the wetting agent is evenly mixed into the mixed material.

[0068] During the process of adding lubricant to the mixture, the mixture sent down by the guide pipe 32 will be continuously mixed with the wetting agent sent in by the third feeding pipe 14 in proportion. Then, the spiral blade 33 on the outside of the guide pipe 32 will rotate with the guide pipe 32, and the mixture with the flow agent and the wetting agent will be sent to the top of the feeding barrel 31 and fall into the gap between the feeding barrel 31 and the first cylinder 11. At this time, the fourth feeding pipe 15 will send the adsorbent into the first cylinder 11 to mix with the mixture. The falling mixture will be mixed with the adsorbent. At the same time, the mixing strips 44 on the outside of the support ring 35 will stir and mix the falling mixture and the adsorbent under the action of following the rotation of the support ring 35, so that they are evenly mixed and fed into the discharge pipe 16.

[0069] After adding the materials:

[0070] After adding the mixed adsorbent, the mixture at this time, i.e., methyl thiophanate wettable powder, will pass from the first preparation tube 1 through the discharge pipe 16 into the second preparation tube 6. At this time, the first motor 51 drives the driving rod 52 to rotate, and the beating rod 53 outside the driving rod 52 will break up the mixture falling from the discharge pipe 16, so that the mixture can fall more evenly on the screen 82. Then, the driving rod 52 drives the pressing plate 71 and the scraping plate 72 to rotate, and the inclined pressing plate 71 can press down and push the mixture to assist the mixture to pass through the screen 82. When the screen 82 sieves the mixture, the vibration motor can be pressed below the sieve plate 81 to vibrate the screen 82 to assist the screen 82 in sieving the mixture.

[0071] During the sieving process:

[0072] The scraper plate 72 will scrape up the mixture that has not passed through the screen 82 and push the mixture to slide on the screen 82 and the sieve plate 81. At this time, the rolling rod 74 rotating on the side of the scraper plate 72 can continuously roll the mixture by rotating to achieve the purpose of crushing and crushing the mixture, so that the mixture can fully pass through the screen 82 for screening, ensuring that the size of the mixture particles is more uniform, thereby increasing the contact area of ​​the plant surface with the methyl thiophanate wettable powder prepared by the device and achieving the purpose of long-term wetting;

[0073] During the sieving process:

[0074] The air supply device 91 in the upper air mechanism 9 dries the air through the dehumidification device 92 and then sends it into the second cylinder 61 through the upper air pipe 93 and the air outlet box 94. The dry air entering the second cylinder 61 will pass through the screen 82 and come into contact with the mixture screened on the screen 82, which can assist the mixture to flow through the screen and at the same time ensure the dryness of the mixture, so as to ensure the quality of the methyl thiophanate wettable powder prepared by the preparation device. Then, the air entering the second cylinder 61 will be discharged from the second cylinder 61 through the air outlet 63, and the sieved methyl thiophanate wettable powder can be discharged from the device through the discharge port 62 for packaging.
