Description

It has no cross-resistance with other commonly used fungicides, and has a longer lasting effect than conventional fungicides, and is highly effective. Selective, safe for crops, humans, animals and beneficial organisms, and basically no pollution to the environment.

There are several problems in the implementation of a certain technology related to the existing method for recovering ammonium chloride, a by-product in the production process of acetostrobin:

1. Add 50g of ammonium chloride by-product, crude ammonium chloride (containing 40g of ammonium chloride), 100g of water and 25g of toluene into a 500ml four-neck bottle, stir and heat up to 70°C for 1 hour, then let it stand for 30 minutes to stratify. Collect the organic phase. The organic phase is simply distilled to 95°C. The solvent is evaporated and 0.64g of the intermediate 2-(2-methylphenoxymethyl)phenyl oxalate methyl ester (content 78%) is recovered. The recovered solvent It can be used continuously. During the distillation process, the temperature and pressure will rise inside the container. When the temperature rises, the water vapor is separated through the distiller. However, during the separation process, there will be residual water droplets at the entrance of the distiller. , generally use a conventional distiller to distill or open the container for wiping, but these methods cannot avoid that after the distillation, water droplets will adhere to the inner wall and even flow back into the liquid, affecting the purity of the liquid and even affecting the subsequent processes of the liquid. Preparation, resulting in problems with the preparation results, making it difficult to ensure quality.

2. After the water phase is filtered and impurities removed at 60°C, the filtrate is cooled and crystallized to 2°C, and 16.6g of high-purity ammonium chloride is obtained by centrifugation. During the filtration process, the filtration effect of the filter gradually decreases after long-term repeated filtration. , usually by replacing the filter or cleaning the filter, but these methods require manual operation to clean them, which consumes a lot of time and money, wasting manpower and maintenance costs.

To sum up, when processing raw materials in the present invention, the raw materials are first poured into the device body 1, heated and distilled through the heating unit 5, and distilled through the distillation unit 2 during the distillation process. After the distillation is completed, the distillation unit 2 Small water droplets are easy to form on the inner wall of the end. At this time, the small water droplets gradually increase. The water droplets are introduced into the water storage tray 301 through the water guide rod 302. After the water in the water storage tray 301 is collected, there are still water droplets remaining on the inner wall. This At this time, due to the increase in water droplets inside the water storage tray 301, the water storage tray 301 gradually moves downward due to gravity, which in turn drives the sliding block 304 to move upward, thereby causing the connecting soft belt 305 to move, thereby driving the reverse bevel gear 306 to rotate, thereby causing the reverse bevel gear 306 to rotate. The bevel teeth 306 drive the rotating gear 307 to rotate, thereby causing the wiping plate 308 to wipe the water droplets on the inner wall clean, and the excess water will fall into the water storage tray 301.

In the present invention, when the distillation process is about to end, the distilled and dehydrated raw materials are introduced into the bottom filter unit 6 through the diversion unit 4 for filtration. At this time, due to the gradual reduction in the amount of water during the distillation process, the liquid at the top of the diversion unit 4 The page gradually lowers, and then drives the buoyancy block 404 to drop, and the buoyancy block 404 drops to wave the guide vertical plate 403, so that the buoyancy block 404 moves downward with the cooperation of the sliding disk 405 and the guide slide 406, thereby causing the side tilt The guide plate 401 tilts, and the liquid is poured inside the bottom filter unit 6. When the liquid is poured, it is reset by the action of the guide spring 407.

In the present invention, when the filter unit 6 is ready to filter, the filter screen 602 filters the filter residue, and the filtrate flows into the liquid storage bin 8 below. At this time, a large amount of filter residue remains on the top of the filter screen 602. When the top surface of the filter residue touches the filter residue sensor 607 , the translation motor 606 starts to move, and the translation screw 608 moves, thereby driving the bottom cleaning telescopic plate 605 to move. The cleaning telescopic plate 605 expands and contracts according to the width of the filter screen 602 during the translation process, and all the filter residue is cleaned to the lower platen. 603 on the top surface, after a certain amount of filter residue accumulates on the top surface of the lower pressure plate 603, the lower pressure plate 603 is pressed down with the assistance of the lower pressure block 611, and the lower pressure plate 603 tilts to collect and recover the filter residue, and the process steps are completed.
