Due to its low toxicity and high efficiency, it is often used in the production of pesticide formulations. However, during the synthesis, refinement, and formulation of pyriproxyfen, strict filtration is required to remove by-products, impurities, and unreacted substances, thereby improving the purity and stability of the product.

[0003] In the prior art, a continuous circulation filtration system for pyriproxyfen was proposed in the Chinese patent document with the publication number CN206916036U.

The pyriproxyfen synthesis kettle is connected to the circulation pump through pipeline A, and the circulation pump is connected to the plate and frame filter through pipeline B. Although this technology has a simple structure, closed operation, safety, and environmental protection, and forms a reflux circulation pipeline through pipeline A, pipeline B, and pipeline C for circulation filtration to ensure the impurity removal rate and improve the product quality, it is the same as the traditional method in that: the traditional filtration system generally adopts a static sedimentation method during filtration, which not only causes uneven liquid flow, makes it difficult for larger impurities to be fully broken and dissolved, not only reduces the dissolution efficiency of soluble impurities, but also easily clogs the filter screen, affecting the overall filtration effect.

A flow disturbance component is arranged inside the sedimentation box 2, and the flow disturbance component is used to crush large impurities in the pyriproxyfen solution, so that it helps to dissolve the soluble components in some impurities faster, improve the dissolution efficiency, and also improve the filtration efficiency, and prevent impurities from clogging the filter screen. A slag cleaning component is arranged at the bottom of the sedimentation box 2, and the slag cleaning component is used to remove sedimentary impurities at the bottom of the sedimentation box 2, so as to avoid impurities remaining in the sedimentation box 2 and reduce secondary pollution. The flow disturbance component and the slag cleaning component are used in conjunction with each other, so that the filtration system can operate continuously without frequent shutdowns for cleaning due to impurity accumulation; By setting the spoiler component and the slag cleaning component, which are used in cooperation with each other, large particulate impurities can be fully broken before filtration, the dissolution efficiency of soluble impurities can be improved, the clogging of the filter screen can be reduced at the same time, and the precipitated impurities can be automatically cleaned after filtration to prevent the accumulation of sediments, achieving the advantages of continuous operation, high-efficiency filtration, and low maintenance costs. It overcomes the defects of traditional filtration systems in terms of dissolution efficiency, impurity treatment, and automatic slag cleaning. As a result, the filtration system can operate continuously without frequent shutdowns for cleaning due to impurity accumulation. At the same time, due to the synchronous operation of the spoiler component and the slag cleaning component, impurities are always in a cycle of being dispersed, broken, settled, and cleaned throughout the filtration process and will not accumulate inside the system, thus achieving a continuous and stable filtration effect.

[0024] As Figures 1 to 8 shown, the spoiler component includes a filter cylinder 13 fixedly connected to the middle part inside the sedimentation tank 2. A rotating column 16 is rotatably connected to the middle part inside the filter cylinder 13. A plurality of wave plates 17 and a plurality of stirring columns 18 are fixedly connected to the outside of the rotating column 16 at equal intervals in a ring shape. The outer shape of the wave plate 17 is wavy. The position of the stirring column 18 is between two adjacent wave plates 17. The length of the wave plate 17 is longer than the length of the stirring column 18. A plurality of impact columns 15 are fixedly connected to the inner wall of the filter cylinder 13 at equal intervals in a ring shape. A plurality of sieve holes 14 are formed in the inner wall of the filter cylinder 13. The input end of the liquid inlet pipe 8 penetrates through the side wall of the sedimentation tank 2 and is connected to the top of one end of the filter cylinder 13. The end of the filter cylinder 13 connected to the liquid inlet pipe 8 is fixedly connected to one side inside the sedimentation tank 2. One end of the filter cylinder 13 away from the liquid inlet pipe 8 is rotatably connected to a turntable 12. The other side of the turntable 12 is rotatably connected to one side inside the sedimentation tank 2. One end of the rotating column 16 penetrates through one end of the filter cylinder 13 and is fixedly connected to one side of the turntable 12. The diameter of the turntable 12 is larger than the diameter of the filter cylinder 13; By setting the spoiler component, the wave plates 17 and the stirring columns 18 can disturb the liquid in multiple directions, so that large particulate impurities are fully broken during the high-speed flow and impact process. At the same time, it promotes the rapid dissolution of soluble impurities, improves the pretreatment efficiency before filtration. At the same time, by providing sieve holes 14 on the inner wall of the filter cylinder 13 and driving the wave plates 17 and the stirring columns 18 to rotate through the rotating column 16, the liquid is continuously stirred, so that the impurities are dispersed and broken before entering the filter screen, thereby reducing the risk of large particulate impurities directly clogging the filter screen, and further extending the service life of the filter screen. At the same time, by setting the multi-point spoiler structure formed by the filter cylinder 13, the wave plates 17, the stirring columns 18, and the impact columns 15, a complex flow path of the liquid is formed inside the filter cylinder 13, ensuring the uniform distribution of impurities in the liquid, and further improving the filtration uniformity and stability. When in use, first, pyriproxyfen during preparation is input into the top inside the filter cylinder 13 through the liquid inlet pipe 8. At this time, the liquid fills to the water level as Figure 5 shown, and at the same time as Figure 4As shown, the turntable 12 drives the rotating column 16 to rotate along the M2 direction. At this time, multiple corrugated plates 17 and multiple stirring columns 18 will rotate synchronously. At the same time, when the corrugated plates 17 rotate, the corrugated plates 17 will cause turbulent flow inside the filter cylinder 13, prompting the corrugated plates 17 to continuously stir the impurities contained in the liquid, causing the large impurities to continuously impact on multiple impact columns 15, thereby promoting the fragmentation of the large impurities, so as to promote the rapid dissolution of the soluble impurities contained in the impurities, thereby improving the pre-treatment efficiency before filtration, and at the same time promoting the improvement of the purity of pyriproxyfen. At the same time, through the multiple stirring columns 18 provided, when the rotating column 16 rotates, the stirring columns 18 form multi-point turbulent flow, making the liquid form a complex flow path inside the filter cylinder 13, ensuring the uniform distribution of impurities in the liquid, and at the same time ensuring that the small particle impurities after fragmentation can quickly pass through multiple sieve holes 14 and deposit at the bottom of the sedimentation tank 2, and at the same time avoiding the problem of multiple small impurities depositing in a pile.

[0025] As Figures 2 to 9 shown, the slag cleaning assembly includes multiple impurity accumulation plates 21 fixedly connected to the inner bottom of the sedimentation tank 2. Between the multiple impurity accumulation plates 21, there are material placement grooves 22 provided pairwise. The positions of the multiple material placement grooves 22 are located at the bottom of the filter cylinder 13. The top and bottom of one side of the turntable 12 are respectively fixedly connected with scraping plates 19. The top of the scraping plate 19 is fixedly connected with multiple scraping claws 20 at equal distances. The specifications and dimensions of the scraping claws 20 are adapted to the specifications and dimensions of the material placement grooves 22. The outer shape of the impurity accumulation plate 21 is semicircular. When the turntable 12 rotates to one side of the impurity accumulation plate 21, the scraping claws 20 on one side of the scraping plate 19 just snap into the material placement grooves 22. Both ends of the multiple impurity accumulation plates 21 are respectively fixedly connected with straight plates 25. Both sides inside the sedimentation tank 2 are respectively fixedly connected with backing plates 29. The position of the straight plate 25 is located on the top of the backing plate 29. An outlet 28 is opened on one side inside the sedimentation tank 2. One of the two backing plates 29 is located inside the outlet 28. A rotating shaft 23 is rotatably connected at the outlet 28 inside the sedimentation tank 2. One side of the sedimentation tank 2 is fixedly connected with a discharge cylinder 26. The top of the discharge cylinder 26 is rotatably connected with a cover plate 27 through a shaft. One side of the top of the discharge cylinder 26 is communicated with the outlet 28 inside the sedimentation tank 2. Multiple dialing plates 24 are fixedly connected to the outside of the rotating shaft 23 at equal distances in a ring shape. The positions of the multiple dialing plates 24 correspond to the positions of the multiple material placement grooves 22, and the specifications and dimensions of the dialing plates 24 are adapted to the specifications and dimensions of the material placement grooves 22. When the dialing plates 24 rotate to the top of the straight plates 25, the bottoms of the multiple dialing plates 24 are respectively snapped into the spaces between the multiple straight plates 25 pairwise; By means of the provided slag cleaning assembly, the structural design of the accumulation plate 21 and the feeding trough 22, the deposited impurities are collected at a specific position and automatically scraped off by the scraper 19 and the scraper claw 20, thereby reducing the accumulation of impurities, improving the cleanliness of the equipment and reducing the risk of secondary pollution. At the same time, the scraper claw 20 cooperates with the feeding trough 22 to scrape the impurities at the bottom of the sedimentation box 2 to the top of the straight plate 25, and automatically pushes the impurities from the discharge port 28 to the inside of the discharge barrel 26 by rotating the toggle plate 24 and the rotating shaft 23. This can promote the automatic discharge of impurities, realize the continuous cleaning of impurities at the bottom of the sedimentation box 2, thereby reducing manual maintenance and improving the operation efficiency of the equipment. At the same time, by means of the cooperation of the semicircular accumulation plate 21, the feeding trough 22 and the toggle plate 24, it is ensured that the deposited impurities can smoothly enter the slag discharge port, and are thoroughly removed by the toggle action of the rotating shaft 23, thereby realizing efficient slag discharge, reducing impurity residues and improving the overall stability of the filtration system. When the broken impurities are deposited at the bottom of the sedimentation box 2, multiple impurities such as Figure 5 As shown, it will be deposited on the top of multiple debris accumulation plates 21. At this time, when the turntable 12 moves along the Figure 4 When the scraper 19 rotates in the direction M1 as shown, the two scrapers 19 will rotate accordingly. When the multiple scraper claws 20 on one side of the scraper 19 rotate to one side of the debris accumulation plate 21, the scraper claws 20 will be stuck in the material storage groove 22. The scraper 19 and the scraper claws 20 will scrape away the impurities deposited on the top of the debris accumulation plate 21 along the direction M1 and scrape to the top of the straight plate 25. At this time, the rotating shaft 23 will move along the direction as shown in FIG. Figure 4 When the rotating shaft 23 rotates, the plurality of toggle plates 24 rotate accordingly, and the impurities remaining on the top of the plurality of straight plates 25 are removed. Figure 5 As shown, the impurities are scraped into the discharge barrel 26 and discharged through the discharge barrel 26, so that the impurities can be automatically discharged, thereby realizing the continuous cleaning of the impurities at the bottom of the sedimentation box 2, thereby reducing manual maintenance and improving the operation efficiency of the equipment. It should be noted that the position of the liquid outlet pipe 7 is as shown in FIG. Figure 5 As shown, it is located in the middle of the liquid water level, which can ensure the output of pyriproxyfen after filtration, facilitate the precipitation of impurities, and also facilitate the rotation of the scraper 19.

[0026] like Figures 1 to 5 As shown, a motor 3 is fixedly connected to one side of the sedimentation box 2, and the output end of the motor 3 penetrates the side wall of the sedimentation box 2 and is fixedly connected to one side of the turntable 12. The end of the rotating column 16 away from the turntable 12 penetrates the side wall of the sedimentation box 2 and is fixedly connected to the driving wheel 4. The end of the rotating shaft 23 penetrates the side wall of the sedimentation box 2 and is fixedly connected to the driven wheel 6. The outside of the driving wheel 4 is connected to the outside of the driven wheel 6 through a belt 5. Through the provided motor 3, driving wheel 4, and driven wheel 6, during normal operation, the motor 3 starts and drives the turntable 12 and the rotating column 16 to rotate. At this time, by setting the rotating column 16 to be fixedly connected to the driving wheel 4, the driving wheel 4 will drive the driven wheel 6 to rotate through the belt 5. At the same time, the rotating shaft 23 will rotate synchronously, achieving a linkage drive mechanism, realizing synchronous flow disturbance and slag cleaning, improving the filtration efficiency, reducing maintenance requirements, and optimizing system stability. The motor 3 drives the turntable 12 and the rotating column 16 to rotate, thereby agitating the liquid inside the sedimentation tank 2, enabling the impurities to be fully turbulently flowed, dispersed, and broken before filtration. The rotating column 16 is fixedly connected to the driving wheel 4, and the driving wheel 4 drives the driven wheel 6 to rotate through the belt 5. The driven wheel 6 then drives the rotating shaft 23 to rotate, enabling the slag cleaning assembly to operate synchronously to clean the deposited impurities. At the same time, it also reduces energy consumption and improves efficiency. This structure uses a single motor 3 to achieve the linkage of multiple components through belt 5 transmission, avoiding multiple independent drive devices and improving the energy efficiency of the system.

[0027] As Figures 1 to 5 shown, a feeding port 9 is provided at the top of the sedimentation tank 2. Inside the top of the sedimentation tank 2, a fixed column 10 is fixedly connected. The bottom end of the fixed column 10 is fixedly connected to a material spreading plate 11, and the outer shape of the material spreading plate 11 is in an inverted U shape. By setting the feeding port 9 and the material spreading plate 11, during daily use, a flocculant can also be added through the feeding port 9 to promote the flocculation of the impurities floating on the liquid surface inside the sedimentation tank 2, thereby accelerating the aggregation of the impurities and improving the sedimentation efficiency. At the same time, with the inverted U-shaped material spreading plate 11, the flocculant put into the feeding port 9 is first evenly dispersed through the material spreading plate 11. This not only avoids the influence of the local high concentration caused by the concentrated feeding of the flocculant on the flocculation effect but also enables the flocculant to fully play its role inside the entire sedimentation tank 2, improving the mixing uniformity.

[0028] The working principle of the present invention: During use, first, the pyriproxyfen during preparation is input through the liquid inlet pipe 8 to the top inside the filter cylinder 13. At this time, the liquid fills to the water level as Figure 5 shown, and at the same time as Figure 4As shown, at this time, the starter motor 3 drives the turntable 12 to rotate, and the turntable 12 drives the rotating column 16 to rotate along the M2 direction. At this time, the multiple wave plates 17 and the multiple stirring columns 18 will rotate synchronously. At the same time, when the wave plate 17 rotates, the wave plate 17 will disturb the flow inside the filter cartridge 13, so that the wave plate 17 continuously stirs the impurities contained in the liquid, and causes the large impurities to continuously impact the multiple impact columns 15, thereby causing the large impurities to be broken, thereby causing the soluble impurities contained in the impurities to be quickly dissolved. At the same time, through the multiple stirring columns 18, when the rotating column 16 rotates, the stirring column 18 forms a multi-point disturbance flow, so that the liquid forms a complex flow path in the filter cartridge 13, ensuring that the impurities in the liquid are evenly distributed, and at the same time ensuring that the broken small particle impurities can quickly pass through the multiple sieve holes 14 and deposit at the bottom of the sedimentation box 2; When the crushed impurities are subsequently deposited at the bottom of the sedimentation tank 2, a plurality of impurities such as Figure 5 As shown, it will be deposited on the top of multiple debris accumulation plates 21. At this time, when the turntable 12 moves along the Figure 4 When the scraper 19 rotates in the direction M1 as shown, the two scrapers 19 will rotate accordingly. When the multiple scraper claws 20 on one side of the scraper 19 rotate to one side of the debris accumulation plate 21, the scraper claws 20 will be stuck in the material storage trough 22, and the scraper 19 and the scraper claws 20 will scrape away the impurities deposited on the top of the debris accumulation plate 21 along the direction M1, and scrape to the top of the straight plate 25 at the same time. At this time, since the rotating column 16 is fixedly connected to the driving wheel 4, the driving wheel 4 drives the driven wheel 6 to rotate through the belt 5, and the driven wheel 6 drives the rotating shaft 23 to rotate, and the rotating shaft 23 will rotate along the direction as shown in FIG. Figure 4 When the rotating shaft 23 rotates, the plurality of toggle plates 24 rotate accordingly, and the impurities remaining on the top of the plurality of straight plates 25 are removed. Figure 5 As shown, the filtered pyriproxyfen is scraped into the discharge tube 26 and discharged through the discharge tube 26, while the filtered pyriproxyfen is output through the liquid outlet pipe 7.
