Description

A solution impurity filtration device for pesticide production Technical Field

[0001] This utility model relates to the field of pesticide production technology, specifically to a solution impurity filtration device for pesticide production. Background Technology

[0002] In pesticide production, solution filtration is a crucial step in ensuring product quality. Traditional processes often use cylindrical filter screens for preliminary filtration of pesticide solutions, utilizing their physical interception properties to separate solid impurities. While this type of filtration device is widely used due to its simple structure and low cost, it has gradually revealed significant shortcomings in actual production.

[0003] After prolonged use, existing cylindrical filters are prone to clogging due to suspended solids, colloids, and crystals in the solution adhering to their surface. This leads to a significant decrease in filtration efficiency and can cause deformation or damage due to frequent disassembly and reassembly. Furthermore, the angled area between the filter and the inner wall of the filtration device often creates cleaning dead zones, making it difficult to thoroughly remove residual impurities through conventional manual washing. This can easily lead to cross-contamination and affect subsequent production processes. Summary of the Invention

[0004] The purpose of this invention is to provide a solution impurity filtration device for pesticide production, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a solution impurity filtration device for pesticide production, comprising a filter screen and a base plate. A support rod is fixedly installed at the top of the base plate, and a first bracket is rotatably connected to the middle of the support rod. A baffle is fixedly connected to one side of the first bracket. A second bracket is fixedly connected to the upper end of the support rod, and one side of the second bracket is fixedly connected to the filter screen. A third bracket is slidably connected to the upper end of the support rod, and a cleaning plate is fixedly connected to one side of the lower end of the third bracket. A return spring is sleeved on the outer wall of the support rod, and the upper end of the return spring is fixedly connected to the third bracket, while the other end of the return spring is fixedly connected to the second bracket. A transmission rod is fixedly connected to the middle of the lower end of the third bracket, and a transmission plate is fixedly connected to the lower end of the transmission rod. The transmission plate has two extrusion grooves. A guide rod is fixedly connected to the lower end of the second bracket. Two filter plates are provided at the lower end of the filter screen, and an extrusion shaft is fixedly connected to one side of each filter plate. The extrusion shaft is slidably connected to the guide rod and to the extrusion groove.

[0006] Preferably, rubber pads are fixedly connected to both sides of the transmission plate, and the rubber pads correspond to the baffles.

[0007] Preferably, the filter screen has a cylindrical structure design, and the filter plate has a semi-circular structure design.

[0008] Preferably, the baffle has an L-shaped structure design, and the corners of the baffle are chamfered.

[0009] Preferably, the extrusion groove is shaped like an inverted V and the two ends of the extrusion groove are arc-shaped.

[0010] Compared with existing technologies, the advantages of this invention are: when the filter screen becomes clogged, simply pressing the first bracket drives the cleaning plate to scrape downwards along the inner wall of the filter screen. Simultaneously, the linkage mechanism drives the filter plate to move, using the edge of the filter screen to centrally scrape away the impurities deposited on the upper part of the filter plate. This structure allows for rapid, periodic cleaning during production, significantly improving the equipment's operational capacity. It also features a simple structure and is easy to maintain.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please refer to Figures 1-3. This utility model provides the following technical solutions:

[0017] Example 1: A solution impurity filtration device for pesticide production includes a filter screen 1 and a base plate 2. A support rod 3 is fixedly installed at the top of the base plate 2. A first bracket 4 is rotatably connected to the middle of the support rod 3. A baffle 5 is fixedly connected to one side of the first bracket 4. A second bracket 6 is fixedly connected to the upper end of the support rod 3. One side of the second bracket 6 is fixedly connected to the filter screen 1. A third bracket 7 is slidably connected to the upper end of the support rod 3. A cleaning plate 8 is fixedly connected to one side of the lower end of the third bracket 7. A return spring 9 is sleeved on the outer wall of the support rod 3. The upper end of the return spring 9 is fixedly connected to the third bracket 7, and the other end of the return spring 9 is fixedly connected to the second bracket 6. A transmission rod 10 is fixedly connected to the middle of the lower end of the third bracket 7. A transmission plate 11 is fixedly connected to the lower end of the transmission rod 10. The transmission plate 11 has two extrusion grooves 12. A guide rod 13 is fixedly connected to the lower end of the second bracket 6. Two filter plates 14 are provided at the lower end of the filter screen 1. An extrusion shaft 15 is fixedly connected to one side of each filter plate 14. The extrusion shaft 15 is slidably connected to the guide rod 13 and the extrusion groove 12.

[0018] In use, when the filter screen 1 becomes clogged and needs cleaning, the first bracket 4 rotates around the support rod 3. The first bracket 4 then drives the second bracket 6 to rotate via the transmission rod 10. The second bracket 6 then drives the filter screen 1 to rotate. When the transmission plate 11 is in contact with the baffle 5, the third bracket 7 is pressed down. The third bracket 7 compresses the return spring 9. At the same time, the third bracket 7 drives the cleaning plate to move downward. The moving cleaning plate cleans the inner wall of the filter screen 1. Simultaneously, the three brackets drive the transmission plate 11 to move downward via the transmission rod 10. The moving transmission plate 11 compresses the compression shaft 15 through the compression groove 12. The pressing extrusion shafts 15 move away from each other along the guide rod 13. The moving extrusion shafts 15 then drive the filter plates 14 to move away from each other. At this time, the impurities on the upper end of the filter plate 14 are scraped off by the filter screen 1. At the same time, the pressing cleaning plate scrapes off the impurities on the inner wall of the filter screen 1, effectively cleaning the filter screen 1 and the filter plate 14. After cleaning, the reset spring 9 drives the third bracket 7 to reset. The third bracket 7 drives the cleaning plate and the transmission rod 10 to reset. The transmission rod 10 drives the transmission plate 11 to reset. The reset transmission plate 11 then squeezes the extrusion shafts 15 through the extrusion groove 12. The squeezed extrusion shafts 15 then drive the filter plates 14 to reset.

[0019] Example 2: This example differs from Example 1 in that the technical solution includes: rubber pads are fixedly connected to both sides of the transmission plate 11, the rubber pads correspond to the baffle 5, the filter screen 1 has a cylindrical structure design, the filter plate 14 has a semi-circular structure design, the baffle 5 has an L-shaped structure design, the corners of the baffle 5 are chamfered, the extrusion groove 12 is opened in an inverted V shape, and the two ends of the extrusion groove 12 are arc-shaped.

[0020] During use, the transmission plate 11 is protected by rubber pads to prevent wear and tear from long-term use. At the same time, the filter plate 14 can filter and support impurities, the filter screen 1 can limit the overall impurities, and the extrusion groove 12 with an inverted V-shape can effectively carry out transmission.

[0021] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
